具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在无线通信系统中，终端与网络侧设备需要通过传输信道进行通信，而传输信道容易受到多种因素的影响，导致通信系统中的传输信道呈现动态变化的特征。在相关技术中，可以通过信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)实时获取物理下行控制信道的信道质量状况。其中，实施方式包括：网络侧设备通过配置信息发送CSI-RS信号至终端。终端对接收的CSI-RS信号进行测量，并将CSI测量结果上报给网络侧设备。网络侧设备根据终端上报的CSI测量结果确定物理下行控制信道的信道质量状况，并进行相关的调度处理。
在相关的无线通信系统中，包括了三种终端上报CSI测量信息的方式。
一种方式中，终端基于周期性上报CSI测量信息。具体为，网络侧设备通过无线资源控制(Radio Resource Control，RRC)信令为终端配置周期性上报CSI测量信息的时频域资源。终端执行对CSI的周期性测量，同时根据对CSI的测量周期进行周期性上报CSI测量信息，并且该方式通过物理上行控制信道(physical uplink control channel，PUCCH)承载CSI测量信息。
另一种方式中，终端采用半持续上报的方式上报CSI测量信息。该方式下用于上报CSI测量信息的资源可以是PUCCH资源，也可以是物理上行共享信道(physical uplink shared channel，PUSCH)资源。其中，终端基于PUSCH资源上报CSI测量信息，包括：终端基于网络侧的动态信令获取用于上报CSI测量信息的资源。并且终端基于PUSCH资源半持续上报CSI测量信息时，可以通过调度请求(Scheduling Request,SR)CSI无线网络临时标识(Radio Network Tempory Identity，RNTI)SP-CSI-RNTI加扰的下行控制信令(Downlink Control Information，DCI)进行激活或去激活终端使用PUSCH资源上报CSI测量信息。终端基于PUCCH资源上报CSI测量信息，包括：网络侧设备可以通过RRC信令为终端配置半静态上报资源。以及，终端使用PUCCH资源半持续上报CSI测量信息时，通过PUCCH资源上的媒体接入控制层控制单元(mediaaccesscontrol，controlelement,MAC-CE)进行激活或去激活终端使用PUCCH资源半持续上报CSI测量信息。示例性的，若终端接收物理下行共享信道(physical downlink shared channel，PDSCH)对应的混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)确认(Acknowledgement，ACK)的时隙为n，则终端上报CSI在n+3N slot subframe，u+1时隙开始生效。
又一种方式中，终端采用非周期性的方式上报CSI测量信息。在该方式中，通过C-RNTI加扰DCI触发终端上报CSI测量信息，并且基于PUSCH资源进行上报。此时，终端上报CSI测量信息由网络侧设备通过DCI中的format 0_1中的CSI Request字段指示。
而针对于低能力终端Redcap UE包括的三种使用场景，例如工厂传感器，视频监控和可穿戴设备。其中，工厂传感器和视频监控设备部署的位置相对固定，因此在工厂传感器和视频监控设备部署的终端的信道状态变化也相对较小。但是，在无线系统中仍然采用上述三种方式上报CSI测量信息，容易导致不要的CSI上报能耗和/或资源开销。
基于上述实施例中涉及到的问题，本公开提供一种信道状态信息CSI上报方法。图1是根据一示例性实施例示出的一种网络设备与终端的通信系统架构图。本公开提供的信道状态信息CSI上报方法。可以应用于图1所示的通信系统架构图中，如图1所示，在终端基于网络侧设备发送的CSI-RS信号对信道状态进行CSI测量，得到CSI测量信息。将该CSI测量信息与上一次CSI测量进行比较。若本次测量的信道状态与上一次测量的信道状态具有比较大的变化，则将本次CSI测量信息上报给网络侧设备。否则，终端不进行CSI测量信息的上报。进一步节省了上报CSI测量信息使用的上报能耗和/或资源开销。
可以理解的是，图1所示的网络设备与终端的通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括的网络设备数量和终端 数量不做限定。
进一步可以理解的是，本公开实施例的无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信系统时，网络设备还可以是车载设备。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
在本公开实施例中，提供一种信道状态信息CSI上报方法。下述实施例将对信道状态信息CSI上报方法结合附图进行说明。
图2是根据一示例性实施例示出的一种信道状态信息CSI上报方法的流程图，如图2所示，信道状态信息CSI上报方法用于终端中，包括以下步骤。
在步骤S11中，确定第一配置参数。
在本公开实施例中，第一配置参数用于指示第一类型终端进行CSI测量信息上报的参数，第一配置参数可以包括CSI测量信息上报门限值。在另一些实施例中，该第一配置参数除了CSI测量信息上报门限值外，还可以包括以下的任一个参数；
测量上报的数量；
测量对象；
用于上报CSI测量信息的上报资源的获取方式。
示例性的，第一类型终端可以是低能力终端redcap UE，或是stationary redcap UE。当然还终端仅仅是举例说明，并不是本公开的具体限定。
在一些实施例中，第一配置参数中至少包括CSI测量信息上报门限值。
在另一些实施例中，第一配置参数还可以包括测量上报的数量；换言之，配置终端需要进行上报的测量项数量。
在又一些实施例中，第一配置参数还可以包括测量对象(例如，下行测量的物理资源)。
在一些实施例中，第一配置参数还可以包括终端用于上报CSI测量信息的上报资源的获取方式。可以理解的是，网络侧设备可以为终端配置多个不同的上报资源的获取方式。
并且，网络侧设备通过高层RRC信令对终端上报CSI信息的第一参数进行配置。并根据第一类型的终端特性，网络侧设备通过RRC信令采用较为固定的周期性配置方式为终端配置第一配置参数。
在步骤S12中，基于CSI测量信息上报门限值，上报CSI测量信息。在本公开实施例中，终端基于网络侧设备配置的CSI测量信息上报门限值，确定是否上报本次的CSI测量信息。在本公开实施例中，CSI测量信息可以是信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)。下面以本次信道状态的CSI测量信息为第一CSI测量值M(n)，上一次信道状态的CSI测量信息为第二CSI测量值M(n-1)，CSI测量信息上报门限值为M_delta为例进行说明。通过本公开上报CSI测量信息的方法，可以有效减少上报CSI测量信息的资源开销。
在本公开一种实施方式中，若第一CSI测量值与第二CSI测量值之间差值大于CSI测量信息上报门限值，则终端上报CSI测量信息。在一些实施例中，该CSI测量信息上报门限值可以为第一CSI测量值与第二CSI测量值之间差值的绝对值，即|M(n)-M(n-1)|>M_delta，则终端上报CSI测量信息。或者，若第一CSI测量值与第二CSI测量值之间差值等于CSI测量信息上报门限值，则终端上报CSI测量信息。在一些实施例中，该CSI测量信息上报门限值可以为第一CSI测量值与第二CSI测量值之间差值的绝对值，即|M(n)-M(n-1)|＝M_delta，则终端上报CSI测量信息。
在本公开的所有实施例中，该CSI测量信息上报门限值可以为第一CSI测量值与第二CSI测量值之间差值，也可以为第一CSI测量值与第二CSI测量值之间差值的绝对值；在本公开的任一个实施例中，不再赘述。
在本公开一种实施方式中，若第一CSI测量值与第二CSI测量值之间差值小于CSI测量信息上报门限值，则终端上报CSI测量信息。在一些实施例中，该CSI测量信息上报门限值可以为第一CSI测量值与第二CSI测量值之间差值的绝对值，即|M(n)-M(n-1)|＜M_delta，则终端上报CSI测量信息。或者，若第一CSI测量值与第二CSI测量值之间差值等于CSI测量信息上报门限值则终端上报CSI测量信息。在一些实施例中，该CSI测量信息上报门限值可以为第一CSI测量值与第二CSI测量值之间差值的绝对值，即|M(n)-M(n-1)|＝M_delta，则终端上报CSI测量信息。
在本公开实施例中，网络侧设备可以为终端配置至少一个CSI测量信息上报门限值。CSI测量信息上报门限值可以根据终端的类型或者终端包括的不同的业务类型分别配置CSI测量信息上报门限值。示例性的，若一类型的终端对信道质量状况要求较为敏感，例如，stationary安全类传感器，则为该类传感器配置一个相对较小的CSI测量信息上报门限值。若终端为普通的视频监控设备，则为该终端配置一个相对较大的CSI测量信息上报门限值。即，不同的业务类型，可以对应不同的CSI测量信息上报门限值；或，不同的终端类型，可以对应不同的CSI测量信息上报门限值；或，同一个终端中不同的业务对信道质量状况要求不同，根据不同的业务要求为终端配置多个CSI测量信息上报门限值。
在本公开实施例中，当终端触发CSI测量信息上报时，可以通过不同的资源进行上报CSI测量信息。在一些实施例中，终端可以主动执行CSI测量信息上报；在一些实施例中，终端可以根据相关的通讯协议规定执行CSI测量信息上报；在一些实施例中，终端可以根据预设触发时间执行CSI测量信息上报。
本公开实施例提出了一种CSI的上报方法，该实施例可以单独被实施，可以与本公开的任何一个其他的实施例一起被实施例。本公开实施例的CSI的上报方法包括：终端通过PUCCH资源上报CSI测量信息。
一种实施方式为，针对于终端基于第一周期对CSI进行周期性测量的情况，网络侧设备为终端配置周期性上报CSI测量信息的PUCCH资源。终端在物理上行控制信道PUCCH资源基于第二周期进行周期性上报CSI测量信息。其中，第二周期与第一周期具有相同的时域资源起始位置与时隙slot长度，第二周期的PUCCH资源时域位置相对于第一周期的时域资源位置偏移N个slot，作为发送当前CSI测量信息的时域资源位置。并且在本公开实施例中，偏移的N个slot需要基于比较CSI测量信息的时间，上行符号起始时间与slot 对齐时间等因素确定。以及还可以根据终端具有的稳定的信道质量状况，适当扩大第一周期和第二周期，例如将第一周期和第二周期增加至1280个时隙等。可以有效减少终端的能耗。在本公开实施例中，终端在物理上行控制信道PUCCH资源基于第二周期进行周期性上报CSI测量信息时，采用PUCCH资源的format 2上报CSI测量信息。采用PUCCH资源的format 2上报CSI测量信息适用于净载荷较小的CSI测量信息，避免了对PUCCH资源的浪费。
另一种实施方式为，针对于终端对CSI进行非周期性测量的情况。网络侧设备通过RRC信令为终端静态配置用于CSI上报的PUCCH时频域资源。基于第一PUCCH资源上报CSI测量信息，第一PUCCH时域资源位置为：相对于CSI测量所对应的时域资源位置偏移N个时隙，作为发送当前CSI测量信息的时域资源位置。该实施方式与上述实施方式类似，为避免对PUCCH资源的浪费，采用PUCCH资源的format 2上报CSI测量信息。采用PUCCH资源的format 2上报CSI测量信息适用于净载荷较小的CSI测量信息。
示例性的，图3是根据一示例性实施例示出的一种信道状态信息CSI上报方法的上报CSI测量信息与CSI测量的时域资源位置偏移时隙的示意图。如图3所示，若N的取值为2，则上报CSI测量信息与CSI测量的时域资源位置偏移2个时隙。
终端基于第二周期上报CSI测量信息，可以使终端能够及时的上报CSI测量信息，并且在信道质量状态变化不大时，终端不需要进行上报CSI测量信息，可以有效降低CSI上报的射频能耗的开销。
在本公开实施例中，偏移的N个时隙资源位置可以基于预定义信息确定。在一些实施例中，可以通过基站配置的信令或通信协议将N设为固定值；在另一些实施例中，可以基于基站配置的信令动态确定偏移值N。终端基于预定义信息确定N的取值，并在相对于CSI测量的时域资源位置偏移N个时隙上报CSI测量信息。另一方式中，还可以通过RRC信令确定N的取值。此时，N的取值可以是灵活变化的。网络侧设备基于终端的处理能力可以基于偏移时隙集合中选择一个候选偏移时隙作为相对于CSI测量的时域资源位置偏移N个时隙上报CSI测量信息。并通过RRC信令将N的取值配置给终端。如上述，基于PUCCH资源不同的时域资源进行CSI测量和上报CSI测量信息，无需复杂的调度流程。
基于PUCCH资源上报CSI测量信息还包括一种方式，终端可以通过第一上行调度请求(Scheduling Request，SR)SR1请求获取上报CSI测量信息的PUCCH资源。在一些实施例中，其中第一上行调度请求SR1专用于请求获取上报CSI测量信息的资源。
当网络侧设备接收到终端发送的专用SR1信令后，为终端分配用于上报CSI测量信息所需的PUCCH资源。根据上述实施例可知，终端上报CSI信息的第一配置参数是由网络 侧确定的，因此，网络侧设备可以确定此时终端上报CSI测量信息的净载荷的大小。当网络侧设备确定此时终端上报CSI测量信息的净载荷较小时，网络侧设备可以指示终端使用PUCCH format 2进行上报CSI测量信息。当网络侧设备确定此时终端上报CSI测量信息的净载荷较大时，网络侧设备可以指示终端使用新的PUCCH格式进行上报CSI测量信息。并且为新的PUCCH格式分配较多的时频资源。网络侧设备通过DCI指令指示终端使用的PUCCH资源位置及格式。
本公开实施例提出了一种CSI的上报方法，该实施例可以单独被实施，可以与本公开的任何一个其他的实施例一起被实施例。本公开实施例的CSI的上报方法包括：终端通过PUSCH资源上报CSI测量信息。
在一种实施方式中，对于终端当前存在可用的PUSCH资源的情况。终端确定当前存在可用的PUSCH资源，则确定使用当前可用的PUSCH资源进行上报CSI测量信息。本公开为方便描述将当前存在可用的PUSCH资源称为第一PUSCH资源。其中，第一PUSCH资源用于同时传输其他上行数据。在本公开实施例中，为将CSI测量信息与其他上行数据区分，使用第一PUSCH资源的MAC CE承载CSI测量信息。MAC CE通过使用上行共享信道(Uplink Shared Channel，UL-SCH)的逻辑信道标识(logical channel identify，LCID)保留值35。在本公开实施例中，CSI测量信息上报MAC CE为可变字节，并且CSI测量信息上报MAC CE的字节是基于上报CSI测量信息包括的测量项的数量确定的。
在另一种实施方式中，终端可以复用承载缓冲状态报告(Buffer Status Report，BSR)的PUSCH资源进行上报CSI测量信息。示例性的，这一实施方式可以应用于当前不存在可用的PUSCH资源且不存在其他可用上行传输的情况。本公开为方便描述将用承载BSR的PUSCH资源称为第二PUSCH资源。在本公开中，CSI测量信息上报使用UL-SCH的LCID的保留值35。示例性的，图4是根据一示例性实施例示出的一种信道状态信息CSI上报方法的复用承载BSR的PUSCH资源上报CSI测量信息的示意图。如图4所示，终端基于一般调度请求SR向网络侧设备请求配置用于上报CSI测量信息的PUSCH资源。网络侧设备接收到终端发送的请求信息后为终端配置PUSCH资源，终端根据网络侧设备配置的PUSCH资源上报CSI测量信息。可以理解的是，由于网络侧设备为终端分配的传输BSR的PUSCH资源较小。因此该实施方式使用于用来承载CSI测量信息的净载荷较小的情况。
在另一种实施方式中，使用用于传输其他上行数据传输的第一PUSCH资源上报CSI测量信息，将CSI测量信息上传至网络侧设备；或，将CSI测量信息与其他上行传输数据一起上传至网络侧设备。示例性的，这一实施方式可以应用于当前不存在可用PUSCH资 源且存在其他上行传输。图5是根据一示例性实施例示出的一种信道状态信息CSI上报方法的使用其他上行数据传输资源上报CSI测量信息的示意图。如图5所示，此时，终端基于一般调度请求SR申请使用PUSCH资源用于上报CSI测量信息。以其他上行数据为BSR为例，基站基于终端发送的调度请求为终端配置用于传输BSR的PUSCH资源。终端传输的BSR将上报CSI测量信息的信令与其他数据的开销一起上报给网络侧设备。网络侧设备基于CSI测量信息的信令与其他数据的开销为终端配置用于上传其他数据和CSI测量信息的PUSCH资源。终端基于PUSCH资源上报CSI测量信息和其他上行数据。在本公开实施例中，上报CSI测量信息通过PUSCH资源的MAC-CE承载，并且使用使用UL-SCH的LCID的保留值35。该实施方式还可以用于CSI测量信息的净载荷较大且无其他上行数据待传输的情况。
在本公开实施例中，基于PUSCH资源上报CSI测量信息还包括一种方式。终端可以发送第二上行调度请求SR2，第二上行调度请求SR2专用于请求获取上报CSI测量信息的第三PUSCH资源，第三PUSCH资源专用于传输CSI测量信息。其实施方式包括，终端发送SR2请求申请用于上报CSI测量信息的第三PUSCH资源，网络侧基于终端专用的调度请求SR2为终端分配用于上报CSI测量信息的第三PUSCH资源。其中第三PUSCH资源的大小基于网络侧设备为终端配置的第一配置参数确定。
在本公开实施例中，通过配置的多种上报CSI测量信息的方式，增加了上报CSI测量信息的灵活性。并且，本公开中涉及的专用SR1和SR2是重新设计的，可以通过不同的时频域资源位置/序列区分一般SR和专用的SR1和SR2。可以理解的是，本公开中重新设计的专用SR1和SR2不会对其他上行调度请求造成影响。
本公开实施例提出了一种CSI的上报方法，该实施例可以单独被实施，可以与本公开的任何一个其他的实施例一起被实施例。本公开实施例的CSI的上报方法包括：终端通过PUCCH资源和PUSCH资源协同进行上报CSI测量信息。
在一些实施例中，当有可用的PUCCH资源时，采用PUCCH资源上报CSI测量信息；当没有可用的PUCCH资源时，采用PUSCH资源上报CSI测量信息。而如何通过PUCCH资源进行上报，可以参考本公开实施例中的任意一种方式，也可以采用相关技术中的任意一种可行方式。相似的，如何通过PUSCH资源进行上报，可以参考本公开实施例中的任意一种方式，也可以采用相关技术中的任意一种可行方式。
在一些实施例中，可以当有可用的PUCCH资源时，采用PUCCH资源上报CSI测量信息；当没有可用的PUCCH资源时，采用PUSCH资源上报CSI测量信息。而如何通过PUCCH资源进行上报，可以参考本公开实施例中的任意一种方式，也可以采用相关技术 中的任意一种可行方式。相似的，如何通过PUSCH资源进行上报，可以参考本公开实施例中的任意一种方式，也可以采用相关技术中的任意一种可行方式。
基于相同或类似的构思，本公开实施例还提供一种信道状态信息CSI上报方法。
图6是根据一示例性实施例示出的一种信道状态信息CSI上报方法的流程图，如图6所示，信道状态信息CSI上报方法用于终端中，包括以下步骤。
在步骤S21中，确定第一配置参数。
在本公开实施例中，第一配置参数用于指示第一类型终端进行CSI测量信息上报的参数，第一配置参数可以包括CSI测量信息上报门限值。在另一些实施例中，该第一配置参数除了CSI测量信息上报门限值外，还可以包括以下的任一个参数；
测量上报的数量；
测量对象；
用于上报CSI测量信息的上报资源的获取方式。
示例性的，第一类型终端可以是低能力终端redcap UE，或是stationary redcap UE。当然还终端仅仅是举例说明，并不是本公开的具体限定。
在一些实施例中，第一配置参数中至少包括CSI测量信息上报门限值。
在另一些实施例中，第一配置参数还可以包括测量上报的数量；换言之，配置终端需要进行上报的测量项数量。
在又一些实施例中，第一配置参数还可以包括测量对象(例如，下行测量的物理资源)。
在一些实施例中，第一配置参数还可以包括终端用于上报CSI测量信息的上报资源的获取方式。可以理解的是，网络侧设备可以为终端配置多个不同的上报资源的获取方式。
并且，网络侧设备通过高层RRC信令对终端上报CSI信息的第一参数进行配置。并根据第一类型的终端特性，网络侧设备通过RRC信令采用较为固定的周期性配置方式为终端配置第一配置参数。
在本公开实施例中，网络侧设备接收终端上报的CSI测量信息。CSI测量信息是由第一类型终端响应于信道状态的第一CSI测量值与第二CSI测量值之间差值大于CSI测量信息上报门限值，上报的CSI测量信息。或CSI测量信息是由第一类型终端响应于信道状态的第一CSI测量值与第二CSI测量值之间差值等于CSI测量信息上报门限值，上报的CSI测量信息。
在本公开实施例中，终端基于网络侧设备配置的CSI测量信息上报门限值，确定是否 上报本次的CSI测量信息。在本公开实施例中，CSI测量信息可以是信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)。下面以本次信道状态的CSI测量信息为第一CSI测量值M(n)，上一次信道状态的CSI测量信息为第二CSI测量值M(n-1)，CSI测量信息上报门限值为M_delta为例进行说明。通过本公开上报CSI测量信息的方法，可以有效减少上报CSI测量信息的资源开销。
在本公开一种实施方式中，若第一CSI测量值与第二CSI测量值之间差值大于CSI测量信息上报门限值，则终端上报CSI测量信息。在一些实施例中，该CSI测量信息上报门限值可以为第一CSI测量值与第二CSI测量值之间差值的绝对值，即|M(n)-M(n-1)|>M_delta，则终端上报CSI测量信息。或者，若第一CSI测量值与第二CSI测量值之间差值等于CSI测量信息上报门限值，则终端上报CSI测量信息。在一些实施例中，该CSI测量信息上报门限值可以为第一CSI测量值与第二CSI测量值之间差值的绝对值，即|M(n)-M(n-1)|＝M_delta，则终端上报CSI测量信息。
在本公开的所有实施例中，该CSI测量信息上报门限值可以为第一CSI测量值与第二CSI测量值之间差值，也可以为第一CSI测量值与第二CSI测量值之间差值的绝对值；在本公开的任一个实施例中，不再赘述。
在本公开一种实施方式中，若第一CSI测量值与第二CSI测量值之间差值小于CSI测量信息上报门限值，则终端上报CSI测量信息。在一些实施例中，该CSI测量信息上报门限值可以为第一CSI测量值与第二CSI测量值之间差值的绝对值，即|M(n)-M(n-1)|＜M_delta，则终端上报CSI测量信息。或者，若第一CSI测量值与第二CSI测量值之间差值等于CSI测量信息上报门限值则终端上报CSI测量信息。在一些实施例中，该CSI测量信息上报门限值可以为第一CSI测量值与第二CSI测量值之间差值的绝对值，即|M(n)-M(n-1)|＝M_delta，则终端上报CSI测量信息。
在本公开实施例中，网络侧设备可以为终端配置至少一个CSI测量信息上报门限值。CSI测量信息上报门限值可以根据终端的类型或者终端包括的不同的业务类型分别配置CSI测量信息上报门限值。示例性的，若一类型的终端对信道质量状况要求较为敏感，例如，stationary安全类传感器，则为该类传感器配置一个相对较小的CSI测量信息上报门限值。若终端为普通的视频监控设备，则为该终端配置一个相对较大的CSI测量信息上报门限值。即，不同的业务类型，可以对应不同的CSI测量信息上报门限值；或，不同的终端类型，可以对应不同的CSI测量信息上报门限值；或同一个终端中不同的业务对信道质量状况要求不同，根据不同的业务要求为终端配置多个CSI测量信息上报门限值。
在本公开实施例中，当终端触发CSI测量信息上报时，可以通过不同的资源进行上报 CSI测量信息。在一些实施例中，终端可以主动执行CSI测量信息上报；在一些实施例中，终端可以根据相关的通讯协议规定执行CSI测量信息上报；在一些实施例中，终端可以根据预设触发时间执行CSI测量信息上报。
本公开实施例提出了一种CSI的上报方法，该实施例可以单独被实施，可以与本公开的任何一个其他的实施例一起被实施例。本公开实施例的CSI的上报方法包括：网络侧设备通过PUCCH资源接收CSI测量信息。
一种实施方式为，针对于终端基于第一周期对CSI进行周期性测量的情况，网络侧设备为终端配置周期性上报CSI测量信息的PUCCH资源。终端在物理上行控制信道PUCCH资源基于第二周期进行周期性上报CSI测量信息。其中，第二周期与第一周期具有相同的时域资源起始位置与时隙slot长度，第二周期的PUCCH资源时域位置相对于第一周期的时域资源位置偏移N个slot，作为发送当前CSI测量信息的时域资源位置。并且在本公开实施例中，偏移的N个slot需要基于比较CSI测量信息的时间，上行符号起始时间与slot对齐时间等因素确定。以及还可以根据终端具有的稳定的信道质量状况，适当扩大第一周期和第二周期，例如将第一周期和第二周期增加至1280个时隙等。可以有效减少终端的能耗。在本公开实施例中，终端在物理上行控制信道PUCCH资源基于第二周期进行周期性上报CSI测量信息时，采用PUCCH资源的format 2上报CSI测量信息。网络侧设备在PUCCH资源的format 2接收CSI测量信息适用于净载荷较小的CSI测量信息，避免了对PUCCH资源的浪费。
另一种实施方式为，针对于终端对CSI进行非周期性测量的情况。网络侧设备通过RRC信令为终端静态配置用于CSI上报的PUCCH时频域资源。基于第一PUCCH资源上报CSI测量信息，第一PUCCH时域资源位置为：相对于CSI测量所对应的时域资源位置偏移N个时隙，作为接受当前CSI测量信息的时域资源位置。该实施方式与上述实施方式类似，为避免对PUCCH资源的浪费，采用PUCCH资源的format 2上报CSI测量信息。网络侧设备基于PUCCH资源的format 2接收CSI测量信息，该方式适用于净载荷较小的CSI测量信息。
示例性的，图7是根据一示例性实施例示出的一种信道状态信息CSI上报方法的接收CSI测量信息与CSI测量的时域资源位置偏移时隙的示意图。如图7所示，若N的取值为2，则上报CSI测量信息与CSI测量的时域资源位置偏移2个时隙。
网络侧设备基于第二周期接收CSI测量信息，可以及时的接收终端上报的CSI测量信息。
在本公开实施例中，偏移的N个时隙资源位置可以基于预定义信息确定。在一些实施 例中，基站可以通过配置的信令或通信协议将N设为固定值；在另一些实施例中，基站可以基于配置的信令动态确定偏移值N。网络侧设备基于预定义信息确定的N的取值，在相对于CSI测量的时域资源位置偏移N个时隙接收CSI测量信息。另一方式中，网络侧设备还可以通过RRC信令确定N的取值。此时，N的取值可以是灵活变化的。网络侧设备基于终端的处理能力可以基于偏移时隙集合中选择一个候选偏移时隙作为相对于CSI测量的时域资源位置偏移N个时隙上报CSI测量信息。并通过RRC信令将N的取值配置给终端。如上述，基于PUCCH资源不同的时域资源进行CSI测量和接收CSI测量信息。
基于PUCCH资源接收CSI测量信息还包括一种方式，网络侧设备基于终端通过第一上行调度请求(Scheduling Request，SR)SR1请求获取上报CSI测量信息的PUCCH资源。在一些实施例中，网络侧设备为终端配置用于上报CSI测量信息的PUCCH资源。其中第一上行调度请求SR1专用于请求获取上报CSI测量信息的PUCCH资源。
当网络侧设备接收到终端发送的专用SR1信令后，为终端分配用于上报CSI测量信息所需的PUCCH资源。根据上述实施例可知，终端上报CSI信息的第一配置参数是由网络侧确定的，因此，网络侧设备可以确定此时终端上报CSI测量信息的净载荷的大小。当网络侧设备确定此时终端上报CSI测量信息的净载荷较小时，网络侧设备可以指示终端使用PUCCH format 2进行上报CSI测量信息。当网络侧设备确定此时终端上报CSI测量信息的净载荷较大时，网络侧设备可以指示终端使用新的PUCCH格式进行上报CSI测量信息。并且为新的PUCCH格式分配较多的时频资源。网络侧设备通过DCI指令指示终端使用的PUCCH资源位置及格式。
本公开实施例提出了一种CSI的上报方法，该实施例可以单独被实施，可以与本公开的任何一个其他的实施例一起被实施例。本公开实施例的CSI的上报方法包括：终端通过PUSCH资源上报CSI测量信息。
在一种实施方式中，对于终端当前存在可用的PUSCH资源的情况。终端确定当前存在可用的PUSCH资源，则确定使用当前可用的PUSCH资源进行上报CSI测量信息。网络侧设备基于终端当前可用的PUSCH资源进行接收CSI测量信息。本公开为方便描述将中当前存在可用的PUSCH资源称为第一PUSCH资源。其中，第一PUSCH资源用于同时传输其他上行数据。在本公开实施例中，为将CSI测量信息与其他上行数据区分，使用第一PUSCH资源的MAC CE承载CSI测量信息。MAC CE通过使用上行共享信道(Uplink Shared Channel，UL-SCH)的逻辑信道标识(logical channel identify，LCID)保留值35。在本公开实施例中，CSI测量信息上报MAC CE为可变字节，并且CSI测量信息上报MAC CE的字节是基于上报CSI测量信息包括的测量项的数量确定的。
在另一种实施方式中，终端可以复用BSR的PUSCH资源进行上报CSI测量信息，网络侧设备基于BSR的PUSCH资源进行接收CSI测量信息。示例性的，这一实施方式可以应用于当前不存在可用的PUSCH资源且不存在其他可用上行传输的情况。本公开为方便描述将用承载BSR的PUSCH资源称为第二PUSCH资源。在本公开中，CSI测量信息上报使用UL-SCH的LCID的保留值35。示例性的，图8是根据一示例性实施例示出的一种信道状态信息CSI上报方法的复用承载BSR的PUSCH资源接收CSI测量信息的示意图。如图8所示，终端基于一般调度请求SR请求向网络侧设备请求配置用于接收CSI测量信息的PUSCH资源。网络侧设备接收到终端发送的请求信息后为终端配置PUSCH资源，网络侧设备根据为终端配置的PUSCH资源接收CSI测量信息。可以理解的是，由于网络侧设备为终端分配的传输BSR的PUSCH资源较小。因此该实施方式使用于用来承载CSI测量信息的净载荷较小的情况。
在另一种实施方式中，网路侧设备可以基于用于传输其他上行数据传输的第一PUSCH资源接收CSI测量信息，或一起接收CSI测量信息与其他上行传输数据。示例性的，这一实施方式可以应用于当前不存在可用PUSCH资源且存在其他上行传输。图9是根据一示例性实施例示出的一种信道状态信息CSI上报方法的使用其他上行数据传输资源接收CSI测量信息的示意图。如图9所示，此时，终端基于一般调度请求SR申请使用PUSCH资源用于上报CSI测量信息。以其他上行数据为BSR为例，网络侧设备基于终端发送的调度请求为终端配置用于传输BSR的PUSCH资源。终端传输的BSR将上报CSI测量信息的信令与其他数据的开销一起上报给网络侧设备。网络侧设备基于CSI测量信息的信令与其他数据的开销为终端配置用于上传其他数据和CSI测量信息的PUSCH资源。网络侧设备基于PUSCH资源接收CSI测量信息和其他上行数据。在本公开实施例中，上报CSI测量信息通过PUSCH资源的MAC-CE承载，并且使用使用UL-SCH的LCID的保留值35。该实施方式还可以用于CSI测量信息的净载荷较大且无其他上行数据待传输的情况。
在本公开实施例中，基于PUSCH资源接收CSI测量信息还包括一种方式。网络侧设备接收终端发送的第二上行调度请求SR2，第二上行调度请求SR2专用于请求获取上报CSI测量信息的第三PUSCH资源，第三PUSCH资源专用于传输CSI测量信息。其实施方式包括，终端发送SR2请求申请用于上报CSI测量信息的第三PUSCH资源，网络侧基于终端专用的调度请求SR2为终端分配用于上报CSI测量信息的第三PUSCH资源。其中第三PUSCH资源的大小基于网络侧设备为终端配置的第一配置参数确定。
在本公开实施例中，通过配置的多种接收CSI测量信息的方式，增加了接收CSI测量信息的灵活性。并且，本公开中涉及的专用SR1和SR2是重新设计的，可以通过不同的时 频域资源位置/序列区分一般SR和专用的SR1和SR2。可以理解的是，本公开中重新设计的专用SR1和SR2不会对其他上行调度请求造成影响。
本公开实施例提出了一种CSI的上报方法，该实施例可以单独被实施，可以与本公开的任何一个其他的实施例一起被实施例。本公开实施例的CSI的上报方法包括：终端通过PUCCH资源和PUSCH资源协同进行上报CSI测量信息。
在一些实施例中，当有可用的PUCCH资源时，采用PUCCH资源上报CSI测量信息；当没有可用的PUCCH资源时，采用PUSCH资源上报CSI测量信息。而如何通过PUCCH资源进行上报，可以参考本公开实施例中的任意一种方式，也可以采用相关技术中的任意一种可行方式。相似的，如何通过PUSCH资源进行上报，可以参考本公开实施例中的任意一种方式，也可以采用相关技术中的任意一种可行方式。
在一些实施例中，可以当有可用的PUCCH资源时，采用PUCCH资源上报CSI测量信息；当没有可用的PUCCH资源时，采用PUSCH资源上报CSI测量信息。而如何通过PUCCH资源进行上报，可以参考本公开实施例中的任意一种方式，也可以采用相关技术中的任意一种可行方式。相似的，如何通过PUSCH资源进行上报，可以参考本公开实施例中的任意一种方式，也可以采用相关技术中的任意一种可行方式。
