具体实施方式
在本申请实施例使用的术语仅仅是出于描述特定实施例的目的，而非限制本申请。本申请和权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其它含义。还应当理解，本文中使用的术语“和/或”是指包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本申请实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，此外，所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
TDD系统可以工作在HD模式，即在同一个时刻，相同频域资源仅能用于UL或者DL。为了更加灵活的使用频域资源，并提高资源利用率，TDD系统也可以工作在FD(Full-Duplex，全双工)模式，即在同一个时刻，相同频域资源同时用于UL和DL，也就是，在相同频域资源上同时处理上行数据和下行数据。
TDD系统中，帧结构被分成DL时隙、UL时隙和S时隙，帧结构一旦确定，UE可以按照帧结构进行数据收发，对于采用HD(Half Duplex，半双工)模式的UE，基站设备(如gNB等)根据帧结构调度UE进行发送或接收。对于采用FD模式的UE，基站设备根据帧结构调度UE的发送、接收或同时发送和接收。
综上所述，基站设备可以配置帧结构，将帧结构通知给UE，以使UE获知帧结构，从而正确进行数据收发。从另一个角度，UE获知帧结构后，可以获知可能存在的UE间干扰，从而采用干扰消除技术来减轻干扰，提高通信可靠性。
一个例子中，在TDD系统下，针对以下行传输为主的帧结构，通常DL时隙配置较多，这就造成UL时隙变少，从而导致上行传输速率受限，并增加上行数据的传输时延，导致上行传输的时延变大，不利用上行业务。
本申请的一个例子中，提出一种数据传输方法，通过SBFD时频资源为UE配置灵活的下行频域资源和上行频域资源，可以在上行频域资源传输上行数据，即能够利用下行时隙或者S时隙配置上行频域资源，并通过上行频域资源传输上行数据，从而能够提高上行传输速率，减少上行数据的传输时延。此外，还可以利用上行时隙或者S时隙配置下行频域资源，并通过下行频域资源传输下行数据，从而能够提高下行传输速率，减少下行数据的传输时延。
本申请一个例子中提出一种数据传输方法，该数据传输方法可以应用于基站设备，参见图1A所示，为数据传输方法的流程示意图，该方法可以包括：
步骤111、确定第一用户设备对应的PDSCH时频资源和第二用户设备对应的SBFD时频资源；其中，PDSCH时频资源和SBFD时频资源可以位于同一下行时隙或者特殊时隙，且SBFD时频资源被指示用于上行和/或保护带宽。
一个例子中，SBFD时频资源可以被指示用于上行，或者，SBFD时频资源被指示用于保护带宽，或者，SBFD时频资源被指示用于上行和保护带宽。其中，被指示用于上行的SBFD时频资源可以为上行子带(UL-subband)。

一个例子中，若SBFD时频资源被指示用于上行，则第二用户设备可以通过该SBFD时频资源发送上行数据，基站设备可以通过该SBFD时频资源接收上行数据。若SBFD时频资源被指示用于保护带宽，则第二用户设备不会通过该SBFD时频资源发送上行数据，基站设备也不会接收上行数据。若SBFD时频资源被指示用于上行和保护带宽，则第二用户设备可以在指示用于上行的资源内发送上行数据，基站设备可以通过指示用于上行的资源接收上行数据。

其中，该频域资源分配消息包括第一指示信息和第二指示信息，第一指示信息用于指示目标RBG的索引，第二指示信息用于指示目标RBG中的第一PRB的数量或者目标RBG中的第二PRB的数量，以使第一用户设备基于第一指示信息和第二指示信息确定可用时频资源。比如说，第一用户设备基于PDSCH时频资源、SBFD时频资源、第一指示信息和第二指示信息，确定可用时频资源。
一个例子中，第一指示信息包括频域资源指示参数，频域资源指示参数用于指示SBFD时频资源占用的第一个RBG的索引和/或SBFD时频资源占用的最后一个RBG的索引；其中，目标RBG包括第一个RBG和/或最后一个RBG。
第二指示信息包括第一PRB资源指示参数和/或第二PRB资源指示参数，第一PRB资源指示参数用于指示第一个RBG中的第一PRB的数量N，且N个PRB与未被SBFD时频资源占用的RBG中PRB是相邻的。第二PRB资源指示参数用于指示最后一个RBG中的第一PRB的数量M，且M个PRB与未被所述SBFD时频资源占用的RBG中PRB是相邻的。
由以上技术方案可见，在SBFD时频资源与PDSCH时频资源重叠的情况下，基站设备可以充分利用PDSCH时频资源来调度UE的传输，UE可以获知PDSCH时频资源，SBFD时频资源配置及PDSCH时频资源配置能够有效实施。从整个系统的角度来看，能够增加小区覆盖范围，减少传输延迟，增加上行传输容量。能够支持TDD系统的数据传输，提高资源利用率，提高网络覆盖和网络容量，增加上行传输资源及小区覆盖范围，减少上行传输延迟并增加上行传输容量。

一个例子中，若SBFD时频资源被指示用于下行，则基站设备可以基于SBFD时频资源发送下行数据。若SBFD时频资源被指示用于保护带宽，则基站设备不会基于SBFD时频资源发送下行数据。若SBFD时频资源被指示用于下行和保护带宽，则基站设备可以基于被指示用于下行的资源发送下行数据。
本申请一个例子中提出一种数据传输方法，该数据传输方法可以应用于第一用户设备，第一用户设备为支持SBFD能力的半双工用户设备，参见图2B所示，为数据传输方法的流程示意图，该方法可以包括：
步骤221、确定PUSCH时频资源(即第一用户设备的PUSCH时频资源)和SBFD时频资源，PUSCH时频资源和SBFD时频资源可以位于同一上行时隙或者特殊时隙，且SBFD时频资源被指示用于下行和/或保护带宽。
步骤222、若PUSCH时频资源和SBFD时频资源存在交叠资源，则基于该PUSCH时频资源和该SBFD时频资源确定可用时频资源；其中，该可用时频资源可以是PUSCH时频资源中除交叠资源之外的时频资源。
步骤223、基于可用时频资源发送第一用户设备对应的上行数据。
一个例子中，基于可用时频资源发送第一用户设备对应的上行数据，可以包括：基于可用时频资源的大小确定目标传输块大小，在可用时频资源上发送与目标传输块大小匹配的上行数据。或，在可用时频资源上对第一用户设备对应的上行数据进行速率匹配，并在可用时频资源上发送速率匹配后的上行数据。
一个例子中，在可用时频资源上发送速率匹配后的上行数据，可以包括但不限于：若速率匹配后的上行数据对应的有效码率小于已设定的有效码率阈值，则可以在可用时频资源上发送速率匹配后的上行数据。
一个例子中，若速率匹配后的上行数据对应的有效码率不小于已设定的有效码率阈值，则禁止在可用时频资源上发送速率匹配后的上行数据。
一个例子中，若可用时频资源包括目标RBG，且目标RBG包括未被SBFD时频资源占用的第一PRB和已被SBFD时频资源占用的第二PRB，那么：基站设备向第一用户设备发送频域资源分配消息，由第一用户设备接收该频域资源分配消息。其中，频域资源分配消息包括第一指示信息和第二指示信息，第一指示信息用于指示目标RBG的索引，第二指示信息用于指示目标RBG中的第一PRB的数量或目标RBG中的第二PRB的数量，以使第一用户设备基于第一指示信息和第二指示信息确定可用时频资源。比如说，第一用户设备基于PUSCH时频资源、SBFD时频资源、第一指示信息和第二指示信息，确定可用时频资源。
一个例子中，第一指示信息包括频域资源指示参数，频域资源指示参数用于指示SBFD时频资源占用的第一个RBG的索引和/或SBFD时频资源占用的最后一个RBG的索引；其中，目标RBG包括第一个RBG和/或最后一个RBG。
第二指示信息包括第一PRB资源指示参数和/或第二PRB资源指示参数，第一PRB资源指示参数用于指示第一个RBG中的第一PRB的数量N，且N个PRB与未被SBFD时频资源占用的RBG中PRB是相邻的。第二PRB资源指示参数用于指示最后一个RBG中的第一PRB的数量M，且M个PRB与未被SBFD时频资源占用的RBG中PRB是相邻的。
一个例子中，PUSCH时频资源为动态调度的PUSCH时频资源，或者，PUSCH时频资源为半持续调度的PUSCH时频资源。SBFD时频资源为半静态配置的SBFD时频资源，或者，SBFD时频资源为动态配置的SBFD时频资源。
由以上技术方案可见，在SBFD时频资源与PUSCH时频资源重叠的情况下，基站设备可以充分利用PUSCH时频资源来调度UE的传输，UE可以获知PUSCH时频资源，SBFD时频资源配置及PUSCH时频资源配置能够有效实施。从整个系统的角度来看，能够增加小区覆盖范围，减少传输延迟，增加下行传输容量。能够支持TDD系统的数据传输，提高资源利用率，提高网络覆盖和网络容量，增加下行传输资源及小区覆盖范围，减少下行传输延迟并增加下行传输容量。
以下结合例子，对本申请的上述技术方案进行说明。
在TDD系统下，帧结构按照时隙可以分为UL时隙、DL时隙和S时隙，S时隙中的符号可以被配置成UL符号、DL符号和F(Flexible)符号，F符号可以用于UL、DL或者GP。其中，上行数据可以在UL时隙传输、在S时隙中的UL符号或F符号传输，上行数据无法在DL时隙传输，也无法在S时隙中的DL符号传输。同理，下行数据可以在DL时隙传输、在S时隙中的DL符号或F符号传输，下行数据无法在UL时隙传输，也无法在S时隙中的UL符号传输。其中，PDSCH传输只能在DL时隙和S时隙中的DL符号或者F符号中进行，而在UL时隙和S时隙中的UL符号，则无法进行PDSCH传输。
全双工通信可以通过SBFD的方式来实现，即可以在时频资源(如UL时隙、DL时隙和S时隙)中配置SBFD时频资源，这样，在同一时刻，在该SBFD时频资源上，可以传输与其它时频资源不同方向的数据。比如说，在DL时隙中配置SBFD时频资源，通过SBFD时频资源传输上行数据，使得上行数据在DL时隙传输。又例如，在S时隙的DL符号配置SBFD时频资源，通过SBFD时频资源传输上行数据，使得上行数据在S时隙的DL符号传输。又例如，在UL时隙中配置SBFD时频资源，通过SBFD时频资源传输下行数据，使得下行数据在UL时隙传输。又例如，在S时隙的UL符号配置SBFD时频资源，通过SBFD时频资源传输下行数据，使得下行数据在S时隙的UL符号传输。
一个例子中，SBFD时频资源可以为SBFD时隙对应的时频资源或者SBFD符号对应的时频资源，SBFD符号可以被定义为基站设备和UE可以配置有SBFD子带(sub-band)的符号，在这些SBFD符号的SBFD子带上(称为SBFD时频资源)，基站设备和UE可以进行全双工通信，也就是说，在SBFD时频资源上，可以进行上行传输、下行传输、或者上下行同时传输。其中，SBFD时频资源可以被明确的指示为上行、下行或者Flexible，当SBFD时频资源被指示为Flexible时，可以在SBFD时频资源灵活的调度上行或者下行。如果SBFD时频资源没有明确指示，则意味着是Flexible，可以用于传输上行或者下行数据。其中，SBFD时隙或者SBFD符号的配置可以包括：DL时隙、UL时隙和F时隙中哪些符号用于SBFD的传输，以及实施的周期和起始点等。为了方便描述，在后续实施例中，以SBFD时频资源为SBFD时隙对应的时频资源为例进行说明。
一个例子中，指示为上行的SBFD称为UL-SBFD，即SBFD时频资源用于上行，指示为下行的SBFD称为DL-SBFD，即SBFD时频资源用于下行。为了支持FD通信，SBFD时频资源可以通过半静态配置，如通过RRC(Radio Resource Control，无线资源控制)信令半静态配置，SBFD时频资源也可以通过动态配置，如通过DCI(Downlink Control Information，下行控制信息)动态配置。
SBFD时频资源可以配置在DL符号、F符号和UL符号中，配置有SBFD时频资源的符号称为SBFD符号，其余未配置SBFD时频资源的符号称为普通符号，即非SBFD符号称为普通符号，如UL符号、DL符号、F符号等。SBFD可以配置在某一时隙的部分符号中，即一个时隙的部分符号是SBFD符号，其余是普通符号，使得DL或者UL数据的传输可能跨越普通符号或SBFD符号。
一个例子中，对于不具备SBFD能力的UE来说，会忽略所有SBFD配置，对于具备SBFD能力的UE来说，该类UE又分为两种，一种是支持SBFD能力的半双工UE，即可以在SBFD时频资源上进行发送或者接收，但是在同一时刻，仅能进行发送或者接收，称为HD UE，另一种是支持SBFD能力的全双工UE，即在同一时刻，可以在SBFD时频资源上同时进行发送和接收，称为FD UE。
一个例子中，如果PDSCH时频资源或者PDSCH重复传输的时频资源跨越SBFD符号和普通符号，需要明确PDSCH在UL-SBFD符号上的传输机制，即给出在UL-SBFD符号中调度PDSCH的技术，比如说，根据PDSCH时频资源与SBFD时频资源的重合情况、以及UE的能力(是否支持FD)进行处理，选择合适的传输策略在相应时频资源中进行PDSCH传输，从而使基站设备和UE 能够有明确的传输机制，实现基站设备和UE之间基于SBFD的全双工通信。通过明确基站设备和UE在SBFD时频资源中对PDSCH的传输策略，可以在子带全双工系统中实现有效的PDSCH传输，从而提高通信系统的整体性能。
其中，与PDSCH时频资源重合的SBFD时频资源，可以为被指示用于上行和/或保护带宽，被指示用于上行的SBFD时频资源记为UL-SBFD时频资源，其中，被指示用于上行的UL-SBFD时频资源可以为上行子带(UL-subband)。被指示用于保护带宽的SBFD时频资源记为保护带宽时频资源，为了方便描述，后续以被指示用于上行的SBFD时频资源为例，即UL-SBFD时频资源。后续过程中的UL-SBFD时频资源可以替换为保护带宽时频资源，也可以替换为UL-SBFD时频资源和保护带宽时频资源，其实现原理类似。
一个例子中，PDSCH时频资源中承载的业务数据可以包括普通业务数据和下行公共控制信息，下行公共控制信息可以包括SIB、寻呼消息、2步随机接入过程中的消息B(MSG-B)、4步随机接入过程中的随机接入消息2(MSG2)、4步随机接入过程中的随机接入消息4(MSG4)等。PDSCH时频资源可以是动态调度的PDSCH时频资源，PDSCH时频资源也可以是SPS(Semi Persistent Scheduling，半持续调度)的PDSCH时频资源。PDSCH时频资源用于传输PDSCH初传数据；或者，PDSCH时频资源用于传输基于HARQ反馈的PDSCH重传数据；或者，PDSCH时频资源用于传输PDSCH重复传输数据。
以下结合具体情况对基于SBFD时频资源的数据传输过程进行说明。
第一、动态调度PDSCH时频资源。
动态调度是指通过DCI来实时地调度PDSCH时频资源，也包括基于HARQ重传的PDSCH时频资源，动态调度的PDSCH时频资源用于传输SIB系统消息、Paging寻呼消息、4步随机接入过程(RACH)中的随机接入消息2(MSG2)、4步随机接入过程中的随机接入消息4(MSG4)、2步随机接入过程(RACH)中的消息B(MSG-B)、以及普通的PDSCH数据(即普通业务数据)。
针对用于传输SIB系统消息和Paging寻呼消息的PDSCH时频资源，通过DCI进行动态调度，在initial BWP中进行传输。在UE完成初始接入之前，UE可能还未获得UL-SBFD的配置(如通过RRC信令配置UL-SBFD)，因此，SIB系统消息和Paging寻呼消息按照DCI调度策略进行传输，无需考虑PDSCH时频资源与UL-SBFD时频资源的冲突，而UE根据DCI中的调度信息接收SIB系统消息和Paging寻呼消息，即接收PDSCH时频资源承载的下行数据。
当UE完成初始接入处于connected(连接)状态，由于SIB系统消息的重要性，且需要一次性发送完成，因此，当PDSCH时频资源用于发送SIB系统消息时，如果除UL-SBFD时频资源之外的时频资源不足以发送SIB系统消息，则不发送SIB系统消息。相反，如果除UL-SBFD时频资源之外的时频资源足以发送SIB系统消息，则正常调度SIB系统消息的发送。对于UE来说，UE是通过DCI来确定是否有SIB系统消息的接收，如果在UL-SBFD时频资源中存在任何上行传输，则取消上行传输，接收SIB系统消息。UE不期待在接收SIB系统消息的同时，接收到通过DCI调度的上行传输。
针对用于传输MSG2、MSG4和MSG-B的PDSCH时频资源，均通过DCI进行动态调度，在initial BWP中进行发送。从单个UE来说，当UE在随机接入过程中时，不会存在单个UE同时发送上行数据和接收下行数据的情况，但是从基站设备的角度来说，存在发送一个UE的下行数据的同时，接收另一个UE的上行数据，基于此，若DL-SBFD时频资源足够PDSCH时频资源传输下行数据，则进行正常传输，否则放弃在与UL-SBFD时频资源重合的符号中发送该PDSCH。
针对普通PDSCH传输，即用于传输普通PDSCH数据(即普通业务数据)的PDSCH时频资源，如果在UL-SBFD时频资源上没有某一UE的PUSCH、PUCCH(Physical Uplink Control Channel，物理上行控制信道)和SRS(Sounding Reference Signal，探测参考信号)传输，则可以在UL-SBFD时频资源之外的可用时频资源上动态调度该UE的PDSCH传输，即通过PDSCH时频资源发送该UE的下行数据。否则，如果在UL-SBFD时频资源上有某一UE的PUSCH、PUCCH或SRS传输，则不应在UL-SBFD符号上动态调度该UE的任何PDSCH传输，然而，这时可以在UL-SBFD时频资源之外的可用时频资源上动态调度其它UE的PDSCH传输。
当可以在UL-SBFD时频资源之外的可用时频资源上动态调度PDSCH时，如果该可用时频资源足够PDSCH传输，则正常调度PDSCH；如果该可用时频资源上仅能够传输部分PDSCH，则可以采用如下方案：
方案1：放弃调度PDSCH，等后面的时隙中有足够资源时再进行调度。
方案2：在可用时频资源上发送部分PDSCH数据。在方案2中，根据可用时频资源的大小，计算实际能够发送PDSCH数据的传输块大小(TBS：Transport Block Size)，然后在该可用时频资源上发送部分PDSCH数据，即与传输块大小匹配的PDSCH数据，而剩余的PDSCH数据在后续时隙中发送。
需要注意的是，在确定可用时频资源的过程中，需要保证PDSCH的解调参考信号(Demodulation Reference Signal：DMRS)在该可用时频资源上不与任何UL-SBFD时频资源冲突，否则，放弃发送PDSCH数据。
方案3：在可用时频资源上对PDSCH数据做速率匹配。在方案3中，基站设备根据实际数据大小为PDSCH数据分配时频资源(PDSCH时频资源)，并通过DCI将分配的时频资源告知UE，基站设备在发送PDSCH数据的过程中，根据实际可用的时频资源执行PDSCH速率匹配。其中，为PDSCH数据分配的时频资源可以大于或等于实际可用的时频资源。在为PDSCH数据分配时频资源的过程中，需要保证PDSCH的DMRS的任意资源元素(Resource Element：RE)在该分配的时频资源上不与任何UL-SBFD时频资源冲突，否则，不执行PDSCH数据的速率匹配，在方案1和方案2中进行选择。
如果上述条件满足，即DMRS的任意资源元素不发生冲突，还需要判断PDSCH数据在可用时频资源上执行速率匹配之后的有效码率是否满足业务需求，比如说，可以通过判断有效码率是否低于为该用户设定的有效码率阈值来实现。如果有效码率低于该有效码率阈值，则正常执行速率匹配；否则，表明速率匹配之后可能无法正常解码，放弃执行速率匹配，在方案1和方案2中进行选择。
在实际组网过程中，有效码率阈值可以根据仿真或者实测结果来设定，对于有效码率阈值的具体值不作规定。有效码率的计算方式可以参见如下公式所示：CREffec＝(TBS+CRC bits)/(Available RE*Qm*Layer)。其中，CRC bits包括传输块(TB：Transport Block)整体CRC校验比特和每个码块(CB：code block)的校验比特，Available RE是所有可以用于传输PDSCH数据的RE数量，需要从所有RE中去掉DMRS、PTRS和其它Overhead占用的RE，并从所有RE中去掉所有不能用于PDSCH数据的RE，如UL-SBFD时频资源中的RE，而UL-SBFD时频资源中的RE可以通过SBFD的配置得出，Qm表示PDSCH数据所使用的调制阶数，而Layer表示PDSCH数据所使用的发送层数。
对于动态调度PDSCH时频资源的以上三种方案，基站设备选择哪种方案来传输PDSCH数据无需告知UE，UE可以自行进行判断。在方案1中，为不发送PDSCH数据，此时基站设备无需向UE发送DCI，UE盲检不到DCI，即无需去接收PDSCH数据。在方案2和方案3中，基站设备均会通过DCI来告知UE此PDSCH数据传输的配置，包括时频资源分配等，UE可以判断PDSCH时频资源有没有与UL-SBFD时频资源重合，继而可以判断出当前使用方案2还是方案3，如果没有重合，则说明使用方案2，否则，如果发生重合，则说明使用方案3。
其中，方案1是禁止数据传输的数据传输方案，方案2和方案3是允许数据传输的数据传输方案，即允许数据传输时可以采用方案2或者方案3。
一个例子中，参见图3所示，为动态调度PDSCH时频资源的示意图，时隙0和时隙1为下行时隙(DL时隙)，时隙2和时隙3为S时隙，时隙2和时隙3的符号为F符号，时隙4为上行时隙(UL时隙)。在时隙1、时隙2和时隙3中，配置有UL-SBFD时频资源，UL-SBFD时频资源两边黑色部分为保护带宽。
参见图3所示，基站设备可以确定UE1对应的PDSCH时频资源、UE2对应的PDSCH时频资源、UE3对应的SBFD时频资源，UE1对应的PDSCH时频资源、UE2对应的PDSCH时频资源和UE3对应的SBFD时频资源可以位于同一下行时隙或者特殊时隙，且该SBFD时频资源被指示用于上行，即UL-SBFD时频资源。
在UL-SBFD时频资源中有UE3的PUSCH数据正在发送，即基于UL-SBFD时频资源接收UE3对应的上行数据，UE3为上述第二用户设备，且第二用户设备可以为支持SBFD能力的半双工用户设备，因此，在UL-SBFD时频资源之外，不能再调度UE3的PDSCH数据，然而，此时SBFD符号上可以调度UE1的PDSCH数据和UE2的PDSCH数据。UE1和UE2为上述第一用户设备，且第一用户设备可以为支持SBFD能力的半双工用户设备。
对于UE1，PDSCH时频资源足够发送PDSCH数据，UE1的PDSCH数据正常进行传输。比如说，由于PDSCH时频资源和UL-SBFD时频资源不存在交叠资源，即PDSCH时频资源足够发送PDSCH数据，因此，基站设备可以基于PDSCH时频资源发送UE1对应的下行数据，UE1可以正常接收下行数据。
对于UE2，PDSCH时频资源不足以发送PDSCH数据，从图3分配的资源可以看出，UE2占用了与UL-SBFD时频资源重合的频域资源部分，UE2的PDSCH数据无法正常进行传输。比如说，若PDSCH时频资源和UL-SBFD时频资源存在交叠资源，则采用方案1进行处理，即，基站设备禁止基于PDSCH时频资源发送UE2对应的下行数据(即PDSCH数据)，UE2也不会接收到下行数据。又例如，若PDSCH时频资源和UL-SBFD时频资源存在交叠资源，则采用方案2进行处理，即，基站设备基于PDSCH时频资源和UL-SBFD时频资源确定可用时频资源，该可用时频资源是PDSCH时频资源中除交叠资源之外的时频资源，并基于可用时频资源的大小确定目标传输块大小，在可用时频资源上发送与目标传输块大小匹配的下行数据(UE2对应的下行数据)，UE2可以通过可用时频资源接收下行数据。又例如，若PDSCH时频资源和UL-SBFD时频资源存在交叠资源，则采用方案3进行处理，即，基于PDSCH时频资源和UL-SBFD时频资源确定可用时频资源，该可用时频资源是PDSCH时频资源中除交叠资源之外的时频资源，并在可用时频资源上对UE2对应的下行数据进行速率匹配，并在可用时频资源上发送速率匹配后的下行数据，UE2可以通过可用时频资源接收速率匹配后的下行数据。在方案3中，若速率匹配后的下行数据对应的有效码率小于已设定的有效码率阈值，则可以在可用时频资源上发送速率匹配后的下行数据。若速率匹配后的下行数据对应的有效码率不小于已设定的有效码率阈值，则禁止在可用时频资源上发送速率匹配后的下行数据。
一个例子中，由于当前UE资源分配方案中，所有频域资源所占用的时域资源相同，因此，UE2的PDSCH数据传输可以使用方案3，即采用速率匹配方案。
第二、半持续调度PDSCH时频资源。
半持续调度(SPS)是指利用半静态RRC配置PDSCH时频资源的配置信息(如发送周期等)，然后利用DCI激活并发送资源配置信息。基于半持续调度的PDSCH时频资源仅用于发送普通PDSCH数据(即普通业务数据，即下行数据)，而不用于发送SIB系统消息、Paging寻呼消息和随机接入过程中的消息。
针对普通PDSCH传输，即用于传输普通PDSCH数据(即普通业务数据)的PDSCH时频资源，如果在UL-SBFD时频资源上没有某一UE的PUSCH、PUCCH和SRS传输，则可以在UL-SBFD时频资源之外的可用时频资源上发送该UE的SPS PDSCH传输(即半持续调度PDSCH时频资源)，即通过PDSCH时频资源发送该UE的下行数据。否则，如果在UL-SBFD时频资源上有某一UE的PUSCH、PUCCH或SRS传输，则不应在UL-SBFD符号上发送该UE的任何SPS PDSCH传输，然而，这时可以在UL-SBFD时频资源之外的可用时频资源上调度其它UE的SPS PDSCH传输。
当可以在UL-SBFD时频资源之外的可用时频资源上调度SPS PDSCH传输时，如果该可用时频资源足够PDSCH传输，则正常调度SPS PDSCH；如果该可用时频资源上仅能够传输部分PDSCH，则可以采用如下方案：
方案1：放弃发送本次SPS PDSCH数据。在发送过程中，基站设备和UE均能够判断SPS PDSCH的时频资源是否全部位于UL-SBFD时频资源之外的时频资源上，如果不是，则基站设备放弃发送SPS PDSCH数据，而UE也不在该时频资源内接收SPS PDSCH数据，但是，UE向基站设备返回NACK，后续过程中，基站设备会利用DCI调度该SPS PDSCH数据的重传。
方案2：在可用时频资源上对SPS PDSCH数据做速率匹配。在方案2中，基站设备根据实际数据大小为PDSCH数据分配时频资源(即PDSCH时频资源)，并在SPS激活过程中通过DCI将分配的时频资源告知UE，基站设备在发送PDSCH数据的过程中，根据实际可用时频资源执行SPS PDSCH速率匹配。
其中，为PDSCH数据分配的时频资源可以大于或等于实际可用的时频资源。在SPS PDSCH数据传输过程中，如果SPS PDSCH的DMRS的任意RE在该分配的时频资源上与任何UL-SBFD时频资源冲突，则不能执行SPS PDSCH数据的速率匹配，选择方案1传输SPS PDSCH数据。
如果上述条件满足，即DMRS的任意资源元素不发生冲突，还需要判断SPS PDSCH数据在可用时频资源上执行速率匹配之后的有效码率是否满足业务需求，比如说，可以通过判断有效码率是否低于为该用户设定的有效码率阈值来实现。如果有效码率低于该有效码率阈值，则正常执行 速率匹配；否则，表明速率匹配之后可能无法正常解码，放弃执行速率匹配，选择方案1，即放弃本次SPS传输。有效码率的计算过程可以参考上述例子，此处不再重复赘述。
对于UE来说，UE在可用时频资源上正常接收SPS PDSCH数据(即速率匹配之后的SPS PDSCH数据)，并进行解码，如果不能正确解码，则UE还可以向基站设备返回NACK，基站设备会利用DCI调度该SPS的重传。
对于半持续调度PDSCH时频资源的以上两种方案，基站设备采用哪一种方案需要明确告知UE，以便UE能够进行正确接收。比如说，可以通过在SPS的RRC配置消息中引入一个信令来完成，也可以在SPS配置激活时通过DCI来指示。其中，如果使用RRC消息来指示，可以在SPS-Config中引入spsRmUlSbfd参数，若该参数配置成enabled，则表明使用方案2，如果该参数未配置，则表明使用方案1。在SPS-Config中引入spsRmUlSbfd参数的示例如下：
其中，如果使用DCI来指示，则可以在DCI中额外引入参数pdschRmUlSbfd，pdschRmUlSbfd的大小是1个比特，如果pdschRmUlSbfd配置为1，则表示使用速率匹配方案，即采用方案2，如果pdschRmUlSbfd配置为0，则表示放弃发送PDSCH数据，即采用方案1。UE在接收到SPS激活消息时，从DCI中解码出该参数pdschRmUlSbfd，从而基于pdschRmUlSbfd的取值确定采用哪个方案。
其中，方案1是禁止数据传输的数据传输方案，方案2是允许数据传输的数据传输方案。显然，基站设备可以向UE发送RRC消息，RRC消息包括数据传输方案的指示信息，如spsRmUlSbfd参数，通过该指示信息表示数据传输方案是允许数据传输(即方案2)，或者，数据传输方案是禁止数据传输(即方案1)。或者，基站设备可以向UE发送DCI消息，DCI消息包括数据传输方案的指示信息，如pdschRmUlSbfd参数，通过该指示信息表示数据传输方案是允许数据传输(即方案2)，或者，数据传输方案是禁止数据传输(即方案1)。
一个例子中，半持续调度PDSCH时频资源的示意图，也可以参见图3所示，UE1对应的PDSCH时频资源、UE2对应的PDSCH时频资源和UE3对应的SBFD时频资源可以位于同一下行时隙或者特殊时隙，且该SBFD时频资源被指示用于上行，即UL-SBFD时频资源。基站设备基于UL-SBFD时频资源接收UE3对应的上行数据，在UL-SBFD时频资源之外，不能再调度UE3的PDSCH数据，然而，SBFD符号上可以调度UE1的PDSCH数据和UE2的PDSCH数据。
对于UE1，由于PDSCH时频资源和UL-SBFD时频资源不存在交叠资源，即PDSCH时频资源足够发送PDSCH数据，因此，基站设备可以基于PDSCH时频资源发送UE1对应的下行数据，UE1可以正常接收下行数据。
对于UE2，PDSCH时频资源和UL-SBFD时频资源存在交叠资源，可以采用方案1进行处理，即，基站设备禁止基于PDSCH时频资源发送UE2对应的下行数据，UE2也不会接收到下行数据。或者，可以采用方案2进行处理，即，基于PDSCH时频资源和UL-SBFD时频资源确定可用时频资源，该可用时频资源是PDSCH时频资源中除交叠资源之外的时频资源，并在可用时频资源上对UE2对应的下行数据进行速率匹配，并在可用时频资源上发送速率匹配后的下行数据，UE2可以通过可用时频资源接收速率匹配后的下行数据。
第三、PDSCH重复传输数据。
对于动态调度的PDSCH时频资源和半持续调度的PDSCH时频资源，均可以传输PDSCH初传数据，也可以传输PDSCH重复传输数据。PDSCH重复传输数据包括RRC配置的PDSCH重复传输数据(PDSCH时频资源传输PDSCH重复传输数据)和HARQ重传数据(PDSCH时频资源用于传输基于HARQ反馈的PDSCH重传数据)，RRC配置的PDSCH重复传输数据包括每次PDSCH传输数据，分为时隙间重复传输数据(时隙级)和时隙内重复传输数据(时隙内)。
如果在UL-SBFD时频资源上没有某一UE的PUSCH、PUCCH和SRS传输，则可以在UL-SBFD时频资源之外的可用时频资源上发送该UE的PDSCH重复传输数据，即通过PDSCH时 频资源发送该UE的PDSCH重复传输数据(重复传输的下行数据)。否则，如果在UL-SBFD时频资源上有某一UE的PUSCH、PUCCH或SRS传输，则不应在UL-SBFD符号上发送该UE的任何PDSCH重复传输数据，然而，这时可以在UL-SBFD时频资源之外的可用时频资源上调度其它UE的PDSCH重复传输数据。
针对PDSCH的HARQ重传数据和时隙间重复传输数据。
一个例子中，PDSCH的HARQ重传数据可以通过下行控制信息(DCI)来调度，HARQ重传数据的TBS与PDSCH初传数据相同，无法在重传时重新计算TBS。PDSCH的时隙间重复传输数据的TBS和时频资源在激活时通过DCI来分配，后续所有PDSCH传输数据均按照该TBS和该时频资源进行发送。
当可以在UL-SBFD时频资源之外的可用时频资源上调度时隙间重复传输数据时，如果该可用时频资源足够PDSCH的所有重复传输数据，则正常调度时隙间重复传输数据或者HARQ重传数据。如果在该可用时频资源上仅能够传输某次PDSCH重复传输的部分数据，则可以采用如下方案：
方案1：放弃发送本次时隙间重复传输数据或者HARQ重传数据。
方案2：在可用时频资源上对时隙间重复传输数据或者HARQ重传数据做速率匹配。无论是时隙间重复传输数据还是HARQ重传数据，基站设备均根据实际PDSCH数据的大小为PDSCH数据分配时频资源(即PDSCH时频资源)。在方案2中，基站设备在发送时隙间重复传输数据或者HARQ重传数据的过程中，可以根据实际可用时频资源执行PDSCH速率匹配。
其中，为PDSCH数据分配的时频资源可以大于或等于实际可用的时频资源。在时隙间重复传输数据或者HARQ重传数据的传输过程中，如果PDSCH的DMRS的任意RE在该分配的时频资源上与任何UL-SBFD时频资源冲突，则不能执行PDSCH数据的速率匹配，选择方案1传输PDSCH数据，即放弃本次时隙间重复传输数据或者HARQ重传数据的传输。
如果上述条件满足，即DMRS的任意资源元素不发生冲突，判断PDSCH数据在可用时频资源上执行速率匹配之后的有效码率是否满足业务需求，比如说，通过判断有效码率是否低于为该用户设定的有效码率阈值来实现。如果有效码率低于该有效码率阈值，则正常执行速率匹配；否则，如果有效码率不低于该有效码率阈值，则表明速率匹配之后可能无法正常解码，放弃执行速率匹配，选择方案1，即放弃本次时隙间重复传输数据或者HARQ重传数据的传输。
对于以上两种方案，基站设备采用哪一种方案需要明确告知UE，以便UE能够进行正确接收。比如说，可以通过在RRC配置消息中引入一个信令来完成，也可以在调度时隙间重复传输数据或者HARQ重传的DCI来指示。其中，如果使用RRC消息来指示，可以引入pdschAggregationRmUlSbfd参数，且该参数仅在pdsch-AggregationFactor配置时才会配置。若该参数配置成enabled，则表明使用方案2，如果该参数未配置，则表明使用方案1。如果使用DCI来指示，则可以复用DCI中额外引入参数pdschRmUlSbfd。UE在接收到DCI消息调度时隙间重复传输或者HARQ重传时，可以从DCI中解码出该参数，从而基于该参数的取值确定采用哪个方案。
方案1是禁止数据传输的数据传输方案，方案2是允许数据传输的数据传输方案，即采用方案2传输本次时隙间重复传输数据或HARQ重传数据的传输。
一个例子中，参见图4所示，为时隙间重复传输数据的示意图，UL-SBFD时频资源两边黑色部分为保护带宽。在图4中，PDSCH重复传输被配置了四次，即需要传输4次时隙间重复传输数据。时隙#0用于传输第一次时隙间重复传输数据，时隙#1用于传输第二次时隙间重复传输数据，时隙#2用于传输第三次时隙间重复传输数据，时隙#3用于传输第四次时隙间重复传输数据。
在时隙#0，由于不存在UL-SBFD时频资源，因此，在时隙#0中可以正常传输第一次时隙间重复传输数据。在时隙#1-#3中，由于存在UL-SBFD时频资源，因此，仅在UL-SBFD时频资源之外发送部分时隙间重复传输数据，而剩余的时隙间重复传输数据则丢弃。可以注意到，在时隙#1发送的时隙间重复传输数据比时隙#2和时隙#3更多，这是由于时隙#1中UL-SBFD时频资源只占用后半时隙的时域资源。或者，在时隙#1-#3中，还可以对时隙间重复传输数据进行速率匹配。
一个例子中，参见图4所示，UE(如支持SBFD能力的半双工UE)对应4次时隙间重复传输数据。针对第一次时隙间重复传输数据，基站设备在时隙#0中可以正常传输第一次时隙间重复传输数据。针对第二次时隙间重复传输数据，基站设备在时隙#1中传输第二次时隙间重复传输数据，基站设备基于UL-SBFD时频资源接收另一UE的上行数据，并调度该UE的第二次时隙间重复传输 数据。由于PDSCH时频资源和UL-SBFD时频资源存在交叠资源，因此，可以采用方案1进行处理，即基站设备禁止基于PDSCH时频资源发送第二次时隙间重复传输数据；或者，可以采用方案2进行处理，即基于PDSCH时频资源和UL-SBFD时频资源确定可用时频资源，该可用时频资源是PDSCH时频资源中除交叠资源之外的时频资源，并在可用时频资源上对第二次时隙间重复传输数据进行速率匹配，并在可用时频资源上发送速率匹配后的第二次时隙间重复传输数据，UE通过可用时频资源接收速率匹配后的第二次时隙间重复传输数据。
针对第三次时隙间重复传输数据，基站设备在时隙#2中传输第三次时隙间重复传输数据，针对第四次时隙间重复传输数据，基站设备在时隙#3中传输第四次时隙间重复传输数据，传输过程参见第二次时隙间重复传输数据。
针对PDSCH的时隙内重复传输数据。
对于时隙内重复传输数据，在某一时隙内最大支持两次重复传输数据，两次重复传输数据使用的频域资源大小相同，时域符号数相同，并可以通过DCI将所分配的时频资源以及每次重复传输数据对应的传输配置指示(Transmission Configuration Indicator：TCI)告知UE。时隙内重复传输数据对应三种传输机制，分别为：时分复用方案A(TDMSchemeA)，频分复用方案A(FDMSchemeA)和频分复用方案B(FDMSchemeB)。对于TDMSchemeA，两次重复传输数据所使用的频域资源相同，时域符号数相同，但是时域上的间隔通过高层信令配置。对于FDMSchemeA和FDMSchemeB，两次重复传输数据使用的时域资源相同，频域资源大小相同，但是频域位置并不相同。根据预编码资源块组(Precoding Resource Group：PRG)的配置不同，频域资源的分配方式也不相同。其中，PRG为wideband时，频域资源的前一半分配给第一次重复传输数据(对应TCI状态1)，另一半分配给第二次重复传输数据(对应TCI状态1)。当PRG为2或4时，频域资源中的偶数PRG分配给第一次重复传输数据，奇数PRG分配给第二次重复传输数据。两种频分复用传输机制的区别在于两次传输的RV版本不同。
当可以在UL-SBFD时频资源之外的可用时频资源上调度时隙内重复传输数据时，如果时隙内重复传输数据分配的时频资源不与UL-SBFD时频资源重合，则可以正常调度所有时隙内的时隙内重复传输数据，如果有任意一次时隙内重复传输数据分配的时频资源与UL-SBFD时频资源重合，则可以采用如下方案：
方案1：放弃发送存在重合的时隙内重复传输数据。
方案2：在未重合时频资源上对时隙内重复传输数据执行速率匹配。在发送时隙内重复传输数据的过程中，基站设备根据实际可用时频资源执行PDSCH速率匹配。其中，为PDSCH数据分配的时频资源大于或等于实际可用的时频资源。在时隙内重复传输数据的传输过程中，如果PDSCH的DMRS的任意RE在该分配的时频资源上与任何UL-SBFD时频资源冲突，则不能执行PDSCH数据的速率匹配，选择方案1，即放弃传输时隙内重复传输数据。
如果上述条件满足，即DMRS的任意RE不发生冲突，判断PDSCH数据在可用时频资源上执行速率匹配之后的有效码率是否满足业务需求，如通过判断有效码率是否低于为该用户设定的有效码率阈值来实现。如果有效码率低于该有效码率阈值，则正常执行速率匹配；否则，如果有效码率不低于该有效码率阈值，表明速率匹配之后可能无法正常解码，放弃执行速率匹配，选择方案1。
一个例子中，参见图5A所示，为时隙内重复传输机制TDMSchemeA的示意图，该例子中存在部分重合的情况。在第二次传输过程中，即传输第二次时隙内重复传输数据，PDSCH的整个时域资源与UL-SBFD时频资源重合，故只能采用方案1，放弃传输第二次时隙内重复传输数据。
一个例子中，参见图5B所示，为时隙内频分复用重复传输机制的示意图，且PRG＝wideband，参见图5C所示，为时隙内频分复用重复传输机制的示意图，且PRG＝2、4，该例子中存在部分重合的情况。在第二次传输过程中，即传输第二次时隙内重复传输数据，PDSCH时域资源存在与UL-SBFD时频资源重合的情况，与图5A不同的是，虽然存在重合情况，但是DMRS并未与UL-SBFD时频资源重合，因此，可以在可用时频资源上通过对PDSCH数据执行速率匹配进行传输，即可以采用方案2。
参见图5B和图5C所示，UE(如支持SBFD能力的半双工UE)对应2次时隙内重复传输数据。针对第一次时隙内重复传输数据，基站设备可以正常传输第一次时隙内重复传输数据，UE可以正常接收第一次时隙内重复传输数据。
针对第二次时隙内重复传输数据，由于PDSCH时频资源和UL-SBFD时频资源存在交叠资源，因此，可以采用方案1进行处理，即基站设备禁止基于PDSCH时频资源发送第二次时隙内重复传输数据；或者，可以采用方案2进行处理，即基于PDSCH时频资源和UL-SBFD时频资源确定可用时频资源，该可用时频资源是PDSCH时频资源中除交叠资源之外的时频资源，并在可用时频资源上对第二次时隙内重复传输数据进行速率匹配，并在可用时频资源上发送速率匹配后的第二次时隙内重复传输数据，UE通过可用时频资源接收速率匹配后的第二次时隙内重复传输数据。
对于以上所有时隙内重复传输类型和机制、以及各机制中不同情况，一旦出现PDSCH重复传输数据所占时频资源与UL-SBFD时频资源重合的情况，则需要明确在这种情况下基站设备采用哪种方案，从而UE也要采用相同的方案去接收。为此，可以通过在RRC配置消息中引入一个信令来完成，也可以通过DCI来指示。如果使用RRC消息来指示，可以在配置重复传输参数时额外引入repetitionRmWithUlSbfd参数，该参数是可选参数，且仅当RepetitionSchemeConfig配置时才会配置。如果该参数未配置，则默认选择方案1，即放弃发送PDSCH重复传输数据；相反，如果该参数已配置，则表明选择方案2，即发送PDSCH重复传输数据。如果使用DCI来指示，则复用DCI中参数pdschRmUlSbfd。
方案1是禁止数据传输的数据传输方案，方案2是允许数据传输的数据传输方案。基站设备可以向UE发送RRC消息，RRC消息包括数据传输方案的指示信息，如repetitionRmWithUlSbfd参数，通过该指示信息表示数据传输方案是允许数据传输(即方案2)，或者，数据传输方案是禁止数据传输(即方案1)。或者，基站设备可以向UE发送DCI消息，DCI消息包括数据传输方案的指示信息，如pdschRmUlSbfd参数，通过该指示信息表示数据传输方案是允许数据传输(即方案2)，或者，数据传输方案是禁止数据传输(即方案1)。
第四、PDSCH频域资源分配。
UL-SBFD时频资源是以PRB(Physical Resource Block，物理资源块)为单位，UL-SBFD时频资源的位置有两种：UL-SBFD时频资源位于整个带宽的一端，或者，UL-SBFD时频资源位于整个带宽的中间，参见图2-图4、图5A-图5C所示，以UL-SBFD时频资源位于整个带宽的中间为例进行说明，UL-SBFD时频资源两侧的黑色部分为保护带宽，保护带宽不能用于任何上行或者下行传输。
对于PDSCH频域资源分配(Frequency Domain Resource Allocation：FDRA)，可以采用FDRA类型0(FDRA Type0：FDRAT0)和FDRA类型1(FDRA Type1：FDRAT1)，FDRA类型0支持非连续资源分配，FDRA类型1支持连续资源分配。对于FDRA类型0，资源分配单位为资源块组(Resource Block Group：RBG)，最小RBG为2个PRB，最大RBG为16个PRB。此外，除了BWP中第一个RBG和最后一个RBG之外，其余RBG需要整个RBG为单位进行调度。
当UL-SBFD时频资源仅占用RBG的部分PRB时，若该RBG不能用于传输PDSCH数据，则会导致频带利用率降低。参见图6所示，为PDSCH频域资源分配的示意图，PDSCH频域资源分配可以采用FDRA类型0，RBG大小可以为8个PRB。在RBG#2中，一共有7个PRB被配置成UL-SBFD时频资源，在RBG#14中，一共有2个PRB被配置成UL-SBFD时频资源，这样，RBG#2和RBG#14中共计有7个PRB不能用于PDSCH数据传输，从而降低了频带利用率。
为了提高频带利用率，使某些RBG中未被UL-SBFD时频资源使用的PRB能够传输下行数据，如图6的RBG2中的PRB#0、RBG14中的PRB#2-7，在DCI格式1-1和DCI格式1-2中的频域资源指示参数Frequency domain resource assignment之外，额外引入PRB资源指示参数，如Prb resource assignment。考虑到UL-SBFD时频资源最大仅配置1个，且UL-SBFD时频资源可能会配置在带宽中间位置，两个RBG中存在部分PRB未被UL-SBFD时频资源占用，因此，PRB资源指示参数最大配置成两个，两个PRB资源指示参数称为PRB resource assignment0和PRB resource assignment1。
比如说，若UL-SBFD时频资源配置在带宽上侧或者带宽下侧，PRB资源指示参数仅使用PRB resource assignment0，若UL-SBFD时频资源配置在带宽中间位置，PRB资源指示参数为PRB resource assignment0和PRB resource assignment1。其中，PRB resource assignment0对应于索引低的RBG(即被UL-SBFD时频资源占用的第一个RBG)，该RBG中部分PRB资源用于UL-SBFD时频资源，PRB resource assignment1对应于索引高的RBG(即被UL-SBFD时频资源占用的最后一个RBG)，该RBG中部分PRB资源用于UL-SBFD时频资源。如果UL-SBFD时频资源比较小，仅占用一个 RBG，则默认使用PRB resource assignment0。参见图6所示，PRB resource assignment0对应RGB2，PRB resource assignment1对应RBG14，这两个参数的基本配置相同，参数值可以根据实际调度进行设定。
一个例子中，PRB资源指示参数仅在FDRA被配置成FDRA类型0时生效并使用，若FDRA被高层信令配置成使用DynamicSwitch(动态开关)模式，则根据Frequency domain resource assignment(频域资源分配)中MSB比特的值来判断，MSB比特的值是0时，表明使用FDRA类型0，新参数生效并使用，MSB比特的值是1时，表明使用FDRA类型1，新参数的大小为0比特，表示不使用。
PRB资源指示参数所占用比特数根据FDRA类型和RBG大小来确定。若FDRA类型1被使用，PRB资源指示参数占用0比特，若FDRA类型0被使用，PRB资源指示参数占用的比特数为log2(RBG size)。PRB资源指示参数所占比特大小根据表1确定，表1是PRB资源指示参数所占比特数。例如，针对图6的PRB resource assignment0和PRB resource assignment1的大小均为3。
表1
在未引入PRB资源指示参数之前，除了BWP中第一个RBG和最后一个RBG外，部分PRB可用的RBG不能被用于PDSCH数据传输。在引入PRB资源指示参数后，部分PRB可用的RBG能够用于PDSCH数据传输，该RBG所对应比特值在Frequency domain resource assignment中被设置成1。以图6为例，假如配置使用FDRA类型0，在引入PRB资源指示参数之前，Frequency domain resource assignment的值为110000000000000111，在引入PRB资源指示参数之后，Frequency domain resource assignment的值为111000000000001111，RBG2和RBG14的位置从0变成1，即针对RBG2和RBG14引入PRB资源指示参数。
PRB资源指示参数的值表示该RBG中可用于PDSCH数据的连续PRB个数，并且该RBG中可以使用的PRB与前一个RBG或者后一个RBG中的PRB是相连的。比如说，PRB resource assignment0用于指示被UL-SBFD时频资源占用的第一个RBG中的连续PRB的数量N，且N个PRB与未被UL-SBFD时频资源占用的RBG中PRB是相邻的。PRB resource assignment1用于指示被UL-SBFD时频资源占用的最后一个RBG中的连续PRB的数量M，且M个PRB与未被UL-SBFD时频资源占用的RBG中PRB是相邻的。
以图6为例，针对索引值小的RBG(被UL-SBFD时频资源占用的第一个RBG)，其PRB资源指示参数PRB resource assignment0的值，如N，表示该RBG中索引数小的连续N个PRB被用于PDSCH数据传输；针对索引值大的RBG(被UL-SBFD时频资源占用的最后一个RBG)，其PRB资源指示参数PRB resource assignment1的值，如M，表示该RBG中索引数大的连续M个PRB被用于PDSCH数据传输。N和M均通过表1中的PRB资源指示参数的值来表示。
由于PRB资源指示参数的值是二进制数，因此，PRB使用的个数是PRB资源指示参数的二进制值所对应的十进制值加1，比如说，二进制数000的十进制为0，则表示1个PRB，二进制数001的十进制为1，则表示2个PRB，二进制数111的十进制为7，表示8个PRB，以此类推。例如，以图6为例进行说明，PRB resource assignment0的值可以设置为000，则N＝1，表示RGB2中有1个PRB可用于PDSCH数据传输。PRB resource assignment1的值可以设置为101，则M＝6，表示RBG14中有7个RPB可用于PDSCH数据传输。
从UE的角度来说，UE根据UL-SBFD时频资源的配置、PDSCH时频资源的FDRA类型0的参数配置、以及DCI中具体值来确定RBG中的PRB使用情况。比如说，根据UL-SBFD时频资源的配置，确定该资源占用的首尾RBG的索引。然后，根据DCI中Frequency domain resource assignment的值，判断首尾RBG是否被PDSCH时频资源所占用，即该RBG所对应的值是否为1。然后，根据首尾RBG的值，确定PRB resource assignment0和PRB resource assignment1两个参数是 否被使用，以及这两个参数的值，从而确定该RBG中连续使用的PRB的个数。然后，根据RBG的大小、所占用RBG的数量，以及RBG中连续使用的PRB的个数，计算出PDSCH时频资源总共使用的PRB的数量，即确定PDSCH时频资源的可用时频资源。
综上所述，若PDSCH的可用时频资源包括目标RBG，目标RBG包括未被SBFD时频资源占用的第一PRB和已被SBFD时频资源占用的第二PRB，则基站设备向UE发送频域资源分配消息，由UE接收基站设备发送的该频域资源分配消息。其中，该频域资源分配消息包括频域资源指示参数(如Frequency domain resource assignment)、第一PRB资源指示参数(如PRB resource assignment0)、第二PRB资源指示参数(如PRB resource assignment1)。频域资源指示参数用于指示SBFD时频资源占用的第一个RBG的索引和SBFD时频资源占用的最后一个RBG的索引。第一PRB资源指示参数用于指示被UL-SBFD时频资源占用的第一个RBG中的第一PRB的数量N，且N个PRB与未被UL-SBFD时频资源占用的RBG中PRB是相邻的。第二PRB资源指示参数用于指示被UL-SBFD时频资源占用的最后一个RBG中的第一PRB的数量M，且M个PRB与未被UL-SBFD时频资源占用的RBG中PRB是相邻的。
在此基础上，UE可以基于PDSCH时频资源、SBFD时频资源、第一PRB资源指示参数和第二PRB资源指示参数，确定PDSCH的可用时频资源。
第五、PUSCH频域资源分配。
PDSCH频域资源分配的方法同样可以适用于PUSCH频域资源分配。在PUSCH频域资源分配过程中，与PUSCH时频资源重合的SBFD时频资源，可以为被指示用于下行和/或保护带宽，被指示用于下行的SBFD时频资源记为DL-SBFD时频资源，其中，被指示用于下行的DL-SBFD时频资源可以为下行子带(DL-subband)。被指示用于保护带宽的SBFD时频资源记为保护带宽时频资源，为了方便描述，以被指示用于下行的SBFD时频资源为例，即DL-SBFD时频资源。后续过程中的DL-SBFD时频资源可以替换为保护带宽时频资源，也可以替换为DL-SBFD时频资源和保护带宽时频资源，其实现原理类似。
比如说，PUSCH频域资源的资源分配单位为RBG，RBG是以PRB为单位，最小RBG为2个PRB，最大RBG为16个PRB。此外，除了BWP中第一个RBG和最后一个RBG之外，其余RBG需要整个RBG为单位进行调度。
当DL-SBFD时频资源仅占用RBG的部分PRB时，若该RBG不能用于传输PUSCH数据传输，则导致频带利用率降低。假设RBG#2一共有7个PRB被配置成DL-SBFD时频资源，RBG#14一共有2个PRB被配置成DL-SBFD时频资源，RBG#2和RBG#14中共有7个PRB不能用于PUSCH数据传输，即RBG#2有1个PRB不能用于PUSCH数据传输，RBG#14有6个PRB不能用于PUSCH数据传输。
为了提高频带利用率，使某些RBG中未被DL-SBFD时频资源使用的PRB能够传输上行数据，在DCI格式0-1和DCI格式0-2中的频域资源指示参数Frequency domain resource assignment之外，额外引入PRB资源指示参数，如Prb resource assignment。考虑到DL-SBFD时频资源最大仅配置1个，且DL-SBFD时频资源可能会配置在带宽中间位置，两个RBG中存在部分PRB未被DL-SBFD时频资源占用，则PRB资源指示参数最大配成两个，即PRB resource assignment0和PRB resource assignment1。
比如说，若DL-SBFD时频资源配置在带宽上侧或带宽下侧，PRB资源指示参数仅使用PRB resource assignment0。若DL-SBFD时频资源配置在带宽中间位置，PRB资源指示参数为PRB resource assignment0和PRB resource assignment1。其中，PRB resource assignment0对应于索引低的RBG(即被DL-SBFD时频资源占用的第一个RBG)，该RBG中部分PRB资源用于DL-SBFD时频资源，PRB resource assignment1对应于索引高的RBG(即被DL-SBFD时频资源占用的最后一个RBG)，该RBG中部分PRB资源用于DL-SBFD时频资源。如果DL-SBFD时频资源比较小，仅占用一个RBG，则默认使用PRB resource assignment0。比如说，PRB resource assignment0可以对应RGB2，PRB resource assignment1可以对应RBG14，这两个参数的基本配置相同，参数值根据实际调度进行设定。
一个例子中，PRB资源指示参数仅在FDRA被配置成FDRA类型0时生效并使用，若FDRA被高层信令配置成使用DynamicSwitch(动态开关)模式，则根据Frequency domain resource assignment(频域资源分配)中MSB比特的值来判断，MSB比特的值是0时，表明使用FDRA类型0，新参数生效并使用，MSB比特的值是1时，表明使用FDRA类型1，新参数的大小为0比特，表示不使 用。
PRB资源指示参数所占用比特数根据FDRA类型和RBG大小来确定。若FDRA类型1被使用，PRB资源指示参数占用0比特，若FDRA类型0被使用，PRB资源指示参数占用的比特数为log2(RBG size)。PRB资源指示参数所占比特大小根据表1确定，表1是PRB资源指示参数所占比特数。
在未引入PRB资源指示参数之前，除了BWP中第一个RBG和最后一个RBG外，部分PRB可用的RBG不能被用于PUSCH数据传输。在引入PRB资源指示参数后，部分PRB可用的RBG能够用于PUSCH数据传输，该RBG所对应比特值在Frequency domain resource assignment中被设置成1。比如说，假如配置使用FDRA类型0，在引入PRB资源指示参数之前，Frequency domain resource assignment的值为000111111111110000，在引入PRB资源指示参数之后，Frequency domain resource assignment的值为001111111111111000，RBG2和RBG14的位置从0变成1，即针对RBG2和RBG14引入PRB资源指示参数。
PRB资源指示参数的值表示该RBG中可用于PUSCH数据的连续PRB个数，并且该RBG中可以使用的PRB与前一个RBG或者后一个RBG中的PRB是相连的。比如说，PRB resource assignment0用于指示被DL-SBFD时频资源占用的第一个RBG中的连续PRB的数量N，且N个PRB与未被DL-SBFD时频资源占用的RBG中PRB是相邻的。PRB resource assignment1用于指示被DL-SBFD时频资源占用的最后一个RBG中的连续PRB的数量M，且M个PRB与未被DL-SBFD时频资源占用的RBG中PRB是相邻的。
由于PRB资源指示参数的值是二进制数，因此，PRB使用的个数是PRB资源指示参数的二进制值所对应的十进制值加1，比如说，二进制数000的十进制为0，则用于表示1个PRB，二进制数001的十进制为1，则用于表示2个PRB，二进制数111的十进制为7，则用于表示8个PRB，以此类推。
从UE的角度来说，UE根据DL-SBFD时频资源的配置、PUSCH时频资源的FDRA类型0的参数配置、以及DCI中具体值来确定RBG中的PRB使用情况。比如说，根据DL-SBFD时频资源的配置，确定该资源占用的首尾RBG的索引。然后，根据DCI中Frequency domain resource assignment的值，判断首尾RBG是否被PUSCH时频资源所占用，即该RBG所对应的值是否为1。然后，根据首尾RBG的值，确定PRB resource assignment0和PRB resource assignment1两个参数是否被使用，以及这两个参数的值，从而确定该RBG中连续使用的PRB的个数。然后，根据RBG的大小、所占用RBG的数量，以及RBG中连续使用的PRB的个数，计算出PUSCH时频资源总共使用的PRB的数量，即确定PUSCH时频资源的可用时频资源。
综上所述，若PUSCH的可用时频资源包括目标RBG，目标RBG包括未被SBFD时频资源占用的第一PRB和已被SBFD时频资源占用的第二PRB，则基站设备向UE发送频域资源分配消息，由UE接收基站设备发送的该频域资源分配消息。其中，该频域资源分配消息包括频域资源指示参数(如Frequency domain resource assignment)、第一PRB资源指示参数(如PRB resource assignment0)、第二PRB资源指示参数(如PRB resource assignment1)。频域资源指示参数用于指示SBFD时频资源占用的第一个RBG的索引和SBFD时频资源占用的最后一个RBG的索引。第一PRB资源指示参数用于指示被DL-SBFD时频资源占用的第一个RBG中的第一PRB的数量N，且N个PRB与未被DL-SBFD时频资源占用的RBG中PRB是相邻的。第二PRB资源指示参数用于指示被DL-SBFD时频资源占用的最后一个RBG中的第一PRB的数量M，且M个PRB与未被DL-SBFD时频资源占用的RBG中PRB是相邻的。
在此基础上，UE可以基于PUSCH时频资源、SBFD时频资源、第一PRB资源指示参数和第二PRB资源指示参数，确定PUSCH的可用时频资源。
一个例子中，基站设备可以确定UE对应的PUSCH时频资源和另一UE对应的SBFD时频资源，PUSCH时频资源和SBFD时频资源可以位于同一上行时隙或者特殊时隙，且SBFD时频资源被指示用于下行。若PUSCH时频资源和SBFD时频资源存在交叠资源，则基站设备可以基于该PUSCH时频资源和该SBFD时频资源确定可用时频资源，该可用时频资源可以是PUSCH时频资源中除交叠资源之外的时频资源，并基于该可用时频资源接收UE对应的上行数据。
UE可以确定PUSCH时频资源和SBFD时频资源，若PUSCH时频资源和SBFD时频资源存在交叠资源，则基于该PUSCH时频资源和该SBFD时频资源确定可用时频资源，该可用时频资 源可以是PUSCH时频资源中除交叠资源之外的时频资源，并基于可用时频资源发送本UE对应的上行数据。
若可用时频资源包括目标RBG，且目标RBG包括未被SBFD时频资源占用的PRB和已被SBFD时频资源占用的PRB，则基站设备向UE发送频域资源分配消息，由UE接收该频域资源分配消息，该频域资源分配消息参见上述例子。
由以上技术方案可见，在SBFD时频资源与PDSCH时频资源重叠的情况下，基站设备可以充分利用PDSCH时频资源来调度UE的传输，UE可以获知PDSCH时频资源，SBFD时频资源配置及PDSCH时频资源配置能够有效实施。从整个系统的角度来看，能够增加小区覆盖范围，减少传输延迟，增加上行传输容量。能够支持TDD系统的数据传输，提高资源利用率，提高网络覆盖和网络容量，增加上行传输资源及小区覆盖范围，减少上行传输延迟并增加上行传输容量。可以明确基站设备和UE在PDSCH数据跨越UL-SBFD符号和普通符号时的调度机制，避免基站设备和UE在此情况下产生行为模糊性，保证基站设备和UE在使能SBFD的情况下都能够正常进行PDSCH数据的传输。
在SBFD时频资源与PUSCH时频资源重叠的情况下，基站设备可以充分利用PUSCH时频资源来调度UE的传输，UE可以获知PUSCH时频资源，SBFD时频资源配置及PUSCH时频资源配置能够有效实施。从整个系统的角度来看，能够增加小区覆盖范围，减少传输延迟，增加下行传输容量。能够支持TDD系统的数据传输，提高资源利用率，提高网络覆盖和网络容量，增加下行传输资源及小区覆盖范围，减少下行传输延迟并增加下行传输容量。
