具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并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，尽管在本公开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，在不脱离本公开实施例范围的情况下，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，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。
在一个实施例中，网络设备可以在上行时域资源为终端配置下行子带。若网络设备可以进行全双工通信，终端可以进行半双工通信，终端在该上行时域单元中，可 以在下行子带内进行下行通信，或在下行子带以外的频域资源上进行上行通信；若网络设备和终端都进行可以进行全双工通信，终端在该上行时域单元中，可以在下行子带内进行下行通信，以及在下行子带以外的频域资源上进行上行通信。
在一个实施例中，网络设备可以在下行时域资源为终端配置上行子带。若网络设备可以进行全双工通信，终端可以进行半双工通信，终端在该下行时域单元中，可以在上行子带内进行上行通信，或在上行子带以外的频域资源上进行下行通信；若网络设备和终端都进行可以进行全双工通信，终端在该下行时域单元中，可以在上行子带内进行上行通信，以及在上行子带以外的频域资源上进行下行通信。
但是并非所有终端都具有全双工能力，如果对于没有全双工能力的终端按照前文实施例配置了子带，可能会导致终端在配置了子带的时域资源内的通信操作发生错乱，而且由于终端不能良好地使用子带通信，还会导致频域资源的浪费。
图1是根据本公开的实施例示出的一种能力指示方法的示意流程图。本实施例所示的能力指示方法可以由终端执行，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述终端可以与网络设备通信，所述网络设备包括但不限于4G、5G、6G等通信系统中的网络设备，例如基站、核心网等。
如图1所示，所述能力指示方法可以包括以下步骤：
在步骤S101中，向网络设备发起随机接入，其中，随机接入所用资源用于指示所述终端是否具有全双工能力。
在一个实施例中，终端在需要与网路设备建立通信连接时，可以向网络设备发起随机接入。其中，随机接入可以是四步随机接入，也可以是两步随机接入，具体可以根据需要选择，本公开并不限制。
终端在进行随机接入的过程中，可以通过随机接入所用资源隐式地向网络设备指示终端具有全双工能力，或者不具有全双工能力，其中，全双工也可以称作子带全双工(Subband Full Duplex，SBFD)。
相对应地，网络设备在与终端进行随机接入的过程中，可以根据终端进行随机接入所用资源确定终端具有全双工能力，或者不具有全双工能力，以便后续可以根据终端的能力对终端做出适当的配置和/或调度。
在一个实施例中，网络设备在确定终端不具有全双工能力的情况下，可以不为终端配置子带。
例如在上行时域资源中不为终端配置下行子带；例如在下行时域资源中不为终端配置上行子带。据此，可以避免不具有全双工能力的终端在时域资源中尝试进行全双工通信而导致的问题，以及避免为终端配置子带而造成的频域资源浪费。
在一个实施例中，时域资源包括以下至少之一：时隙(slot)、符号(symbol)，例如符号可以是正交频分复用符号(Orthogonal Frequency Division Multiplexing，OFDM)符号。
在一个实施例中，网络设备在确定终端不具有全双工能力的情况下，即便为终端配置了子带，也不调度终端在子带上进行通信。
在一个实施例中，网络设备在确定终端具有全双工能力的情况下，可以为终端配置子带。在一个实施例中，网络设备在为终端配置子带的情况下，还可以调度终端在子带上进行通信。
例如在上行时域资源中为终端配置下行子带，那么可以调度终端在上行时域资源的下行子带中进行下行通信，还可以调度终端在上行时域资源对应的下行子带以外的频域资源中进行上行通信，从而实现终端在上行时域资源内的全双工通信。
例如在下行时域资源中为终端配置上行子带，那么可以调度终端在下行时域资源的上行子带中进行上行通信，还可以调度终端在下行时域资源对应的上行子带以外的频域资源中进行下行通信，从而实现终端在下行时域资源内的全双工通信。
例如在灵活时域资源中为终端配置上行子带，那么可以调度终端在灵活时域资源的上行子带中进行上行通信，还可以调度终端在灵活时域资源对应的上行子带以外的频域资源中进行下行通信，从而实现终端在灵活时域资源内的全双工通信。
在一个实施例中，网络设备可以先为多个终端(例如同一个小区内的所有终端)配置子带。而后，根据各个终端的随机接入过程确定各个终端是否具有全双工能力。对于具有全双工能力的终端后，再调度具有全双工能力的终端在子带上进行通信，而对于不具有全双工能力的终端，则不调度在子带上进行通信。
例如在下行时域资源中为终端#1、终端#2、终端#3配置了上行子带，终端#1、终端#2、终端#3分别在随机接入过程中，通过随机接入所用资源指示了各自是否具有全双工能力，例如终端#3具有全双工能力，终端#1、终端#2不具有全双工能力。
网络设备可以调度终端#3在下行时域资源的上行子带中进行上行通信，和/或调度终端#3在下行时域资源对应的上行子带以外的频域资源中进行下行通信，从而实 现终端#3在下行时域资源内的全双工通信。基站不调度终端#1或终端#2在下行时域资源的上行子带中进行上行通信，以免终端#1和终端#2在没有全双工能力的情况下，尝试进行全双工通信而出现问题。
可见，根据本公开的实施例，终端可以通过随机接入所用资源向网络设备指示终端是否具有全双工能力，从而使得网络设备可以确定终端是否具有全双工能力，以便网络设备根据终端的能力为终端做出适当的配置、调度。有利于确保具有全双工能力的终端能够及时受到网络设备的调度进行全双工通信，从而提高通信效率，避免不具有全双工能力的终端被网络设备调度进行全双工通信而出现问题。
需要说明的是，本公开实施例中终端是否具有全双工能力，可以是根据终端的能力确定的，例如终端能支持在同一个时域资源的子带内进行第一传输方向的通信，和/或在子带之外的频域资源进行第二传输方向的通信，那么可以确定终端具有全双工能力。其中，第一传输方向和第二传输方向为不同传输方向，例如在第一传输方向为上行时，第二传输方向为下行，或者，在第一传输方向为下行时，第二传输方向为上行。
或者，本公开实施例中终端是否具有全双工能力，可以是由终端根据需要设置的，例如终端虽然具有全双工能力，但是出于某些考虑，例如在需要省电的情况下，或者在终端的业务数据量小，对时延要求不高的场景中，可以不上报终端具有全双工能力，以免网络设备在同一个时域资源中，既在子带内配置终端进行第一传输方向的通信，又在子带之外的频域资源进行第二传输方向的通信，而导致终端短时间内耗电量较大。
另外，具有全双工能力的终端进行随机接入所用的资源，可以与不具有全双工能力的终端进行随机接入所用的资源相同，在这种情况下，网络设备认为终端不具有全双工能力。换言之，具有全双工能力的终端也可以使用与非全双工能力的终端相同的随机接入的资源，用于随机接入网络设备，在该场景下，认为具有全双工能力的终端没有上报其具有全双工能力。
在一个实施例中，所述资源包括以下至少之一：码域资源；随机接入时机。
在一个实施例中，所述码域资源包括前导码(preamble)。
图2是根据本公开的实施例示出的另一种能力指示方法的示意流程图。如图2所示，所述向网络设备发起随机接入，包括：
在步骤S201中，向所述网络设备发送第一索引对应的前导码，也即前导码的索引为第一索引，其中，所述第一索引对应的前导码用于指示所述终端具有全双工能力；或者，向所述网络设备发送第二索引对应的前导码，也即前导码的索引为第二索引，其中，所述第二索引对应的前导码用于指示所述终端不具有全双工能力。
需要说明的是，图2所示实施例可以独立实施，也可以与本公开中至少一个其他实施例结合实施，具体可以根据需要选择，本公开并不限制。另外，具有全双工能力的终端也可以向网络设备发送第二索引对应的前导码，在这种情况下，网络设备可以确定终端不具有全双工能力。也就是说，具有全双工能力的终端可以通过发送第二索引对应的前导码上报其不具有全双工能力，或者不启动全双工功能。
在一个实施例中，终端在进行随机接入过程中，可以向网络设备发送前导码，而前导码可以具有索引(index)，终端可以通过不同索引的前导码，对终端的全双工能力形成区别指示。例如通过第一索引对应的前导码，可以指示终端具有全双工能力，或者启动终端的全双工功能；例如通过第二索引对应的前导码，可以指示终端不具有全双工能力，或者不启动终端的全双工功能。
相对应地，网络设备在接收到终端发送的前导码后，可以确定前导码的索引，进而根据前导码的索引确定终端是否具有全双工能力。例如在确定前导码的索引为第一索引时，可以确定终端具有全双工能力，进而可以在为终端配置的子带内调度终端进行通信；例如在确定前导码的索引为第二索引时，可以确定终端不具有全双工能力，那么可以不在为终端配置的子带内调度终端进行通信。
在一个实施例中，网络设备可以通过广播信令向终端发送公共随机接入信道配置(RACH-ConfigCommon，其中RACH全称为Random Access Channel)，所述广播信令包括但不限于：系统信息块(System Information Block，SIB)，例如SIB1；其他系统信息(Other System Information，OSI)。
其中，公共随机接入信道配置中的配置包括但不限于：随机接入时机(Randomaccess Occasion，RO)、随机接入时机与同步信号块(Synchronization Signal Block，SSB)的映射关系、前导码的总数目等。公共随机接入信道配置中的配置可以适用于多个终端(例如一个小区的所有终端)，包括具有全双工能力的终端和不具有全双工能力的终端。换言之，这多个终端都可以使用公共随机接入信道配置中的配置进行随机接入。
在一个实施例中，所述方法还包括：根据所述网络设备发送的第一指示信息确定所述第一索引的范围。
在一个实施例中，网络设备可以在广播信令中携带第一指示信息，第一指示信息用于指示第一索引的范围，第一索引为具有全双工能力的终端进行随机接入时需要使用的前导码的索引。其中，需要使用的前导码属于公共随机接入信道配置所配置的前导码。例如可以指示起始索引index S和结束索引index E，进而具有全双工能力的终端在进行随机接入时，可以选择index S至index E之间的索引对应的前导码发送至网络设备，用于指示其具有全双工能力的。而不具有全双工能力的终端在进行随机接入时，可以选择index S至index E之外的索引对应的前导码发送至网络设备，用于指示其不具有全双工能力。或者，具有全双工能力的终端在进行随机接入时，也可以选择index S至index E之外的索引对应的前导码发送至网络设备，用于指示其不具有全双工能力，或者不启动其全双工功能。
网络设备在接收到终端发送的前导码后，在确定前导码的索引处于index S至index E之间时，可以确定终端具有全双工能力，在确定前导码的索引处于index S至index E之外时，可以确定终端部具有全双工能力。
例如公共随机接入信道配置所配置的前导码包括56个前导码，索引从0至55，分别为preamble#0至preamble#55。网络设备通过第一指示信息可以指示索引范围0至9对应的前导码为具有全双工能力的终端进行随机接入时需要使用的前导码。
具有全双工能力的终端在进行随机接入时，可以使用preamble#0至preamble#9中任一个preamble，从而网络设备在终端发送的前导码的索引处于0至9之间时，可以确定终端具有全双工能力。而不具有全双工能力的终端在进行随机接入时，可以使用preamble#10-preamble#55中任一个preamble，从而网络设备在终端发送的前导码的索引处于10至55之间时，可以确定终端不具有全双工能力。
在一个实施例中，所述方法还包括：根据所述网络设备发送的第二指示信息具有全双工能力的终端进行随机接入时需要使用的前导码。
在一个实施例中，网络设备可以在广播信令中携带第二指示信息，第二指示信息用于指示具有全双工能力的终端进行随机接入时需要使用的前导码，其中，需要使用的前导码不属于公共随机接入信道配置所配置的前导码。例如公共随机接入信道配置所配置的前导码为preamble#0至preamble#55，网络设备可以通过第二指示信息额 外指示56至63对应的前导码preamble#56-preamble#63，并指示前导码preamble#56-preamble#63供具有全双工的终端发起随机接入使用。
具有全双工能力的终端在进行随机接入时，可以使用preamble#56-preamble#63中任一个preamble，从而网络设备在终端发送的前导码的索引处于56至63之间时，可以确定终端具有全双工能力。而不具有全双工能力的终端在进行随机接入时，可以使用公共随机接入信道配置所配置的前导码，例如使用preamble#0-preamble#55中任一个preamble，从而网络设备在终端发送的前导码的索引处于0至55之间时，可以确定终端不具有全双工能力。或者，具有全双工能力的终端在进行随机接入时，也可以使用公共随机接入信道配置所配置的前导码，例如使用preamble#0-preamble#55中任一个preamble，从而网络设备在终端发送的前导码的索引处于0至55之间时，可以认为终端不具有全双工能力，或者不启动全双工功能。
以上实施例主要是通过随机接入过程中发送的前导码的索引来区分终端是否具有全双工能力，在这种情况下，具有全双工能力的终端和不具有全双工能力的终端，可以在相同的随机接入时机上发起随机接入，也可以在不同的随机接入时机上发起随机接入，具体可以根据需要选择，本公开并不限制。
图3是根据本公开的实施例示出的又一种能力指示方法的示意流程图。如图3所示，所述向网络设备发起随机接入，包括：
在步骤S301中，在第一随机接入时机向所述网络设备发起随机接入，其中，所述第一随机接入时机用于指示所述终端具有全双工能力；或者，在第二随机接入时机向所述网络设备发起随机接入，其中，所述第二随机接入时机用于指示所述终端不具有全双工能力。
需要说明的是，图3所示实施例可以独立实施，也可以与本公开中至少一个其他实施例结合实施，具体可以根据需要选择，本公开并不限制。另外，具有全双工能力的终端也可以在第二随机接入时机向网络设备发起随机接入，在这种情况下，网络设备可以确定终端不具有全双工能力。
在一个实施例中，网络设备通过公共随机接入信道配置，可以为终端配置多个随机接入时机，终端可以在多个随机接入时机中选择随机接入时机向终端发起随机接入，例如可以通过不同的随机接入时机对终端的全双工能力形成区别指示。例如在第一随机接入时机向网络设备发起随机接入时，可以指示终端具有全双工能力；例如在 第二随机接入时机向网络设备发起随机接入时，可以指示终端不具有全双工能力。
相对应地，网络设备与终端进行随机接入时，可以确定终端进行随机接入所使用的随机接入时机，进而根据随机接入时机确定终端是否具有全双工能力。例如在确定终端在第一随机接入时机进行随机接入时，可以确定终端具有全双工能力，进而可以在为终端配置的子带内调度终端进行通信；例如在确定终端在第二随机接入时机进行随机接入时，可以确定终端不具有全双工能力，那么可以不在为终端配置的子带内调度终端进行通信。
在一个实施例中，网络设备可以通过广播信令向终端发送公共随机接入信道配置，所述广播信令包括但不限于：系统信息块，例如SIB1；其他系统信息。
其中，公共随机接入信道配置中的配置包括但不限于：随机接入时机、随机接入时机与同步信号块的映射关系、前导码的总数目等。公共随机接入信道配置中的配置可以适用于所有终端，也即具有全双工能力的终端和不具有全双工能力的终端，都可以使用公共随机接入信道配置中的配置进行随机接入。
在一个实施例中，所述第一随机接入时机为根据公共随机接入信道配置确定的随机接入时机；和/或，所述第二随机接入时机为根据公共随机接入信道配置确定的随机接入时机。
在一个实施例中，所述方法还包括：根据所述网络设备发送的第三指示信息确定具有全双工能力的终端进行随机接入时需要使用的随机接入时机，和/或，不具有全双工能力的终端进行随机接入时需要使用的随机接入时机。
在一个实施例中，网络设备可以在广播信令中携带第三指示信息，第三指示信息用于指示具有全双工能力的终端进行随机接入时需要使用的随机接入时机，和/或，用于指示不具有全双工能力的终端进行随机接入时需要使用的随机接入时机，其中，具有全双工能力的终端进行随机接入时需要使用的随机接入时机和/或不具有全双工能力的终端进行随机接入时需要使用的随机接入时机可以属于公共随机接入信道配置所配置的随机接入时机。例如可以在公共随机接入信道配置所配置的多个随机接入时机RO#1至RO#10中指示RO#1，进而具有全双工能力的终端可以在RO#1上进行随机接入；而不具有全双工能力的终端可以在RO#2至RO#9中任一RO上进行随机接入。
网络设备在与终端进行随机接入时，在确定终端使用的随机接入机会为RO#1时，可以确定终端具有全双工能力，在确定终端使用的随机接入机会为RO#2至RO#9 中任一RO时，可以确定终端不具有全双工能力。
在一个实施例中，所述第二随机接入时机为根据公共随机接入信道配置确定的随机接入时机；和/或，所述第一随机接入时机为根据所述第二随机接入时机和频域偏移确定的随机接入时机。
在一个实施例中，具有全双工能力的终端在根据公共随机接入信道配置确定第二随机接入时机后，可以根据第二随机接入时机和频域偏移(offset)确定的第一随机接入时机，例如在第二随机接入时机的基础上加上频域偏移得到第一随机接入时机。
据此，具有全双工能力的终端进行随机接入时，就可以不使用公共随机接入信道配置所配置的机接入时机了，从而不会占用不具有全双工能力的终端进行随机接入时所能使用的随机接入时机，那么不具有全双工能力的终端在进行随机接入时，能够使用公共随机接入信道配置所配置的任一随机接入时机了。
图4A是根据本公开的实施例示出的一种随机接入时机的示意图。图4B是根据本公开的实施例示出的另一种随机接入时机的示意图。
如图4A所示，例如网络设备通过公共随机接入信道配置中的随机接入信道配置的索引(RACH configuration index)等于27，该配置中随机接入时机可以分布在多个时隙(slot)中，每个时隙中存在一个随机接入时机。
例如终端根据时分双工上下行配置(TDD UL-DL configuration，其中，TDD全称Time Division Duplexing)确定的TDD结构为DDDSUDDDSU。其中，“D”表示DL slot，“S”表示flexible slot，“U”表示UL slot。也即slot#0至slot#2和slot#5至slot#7位下行时隙，slot#3和slot#8为灵活(flexible)时隙，slot#4和slot#9为上行时隙。
据此可以确定只能在slot#4和slot#9进行上行通信，因此只能在slot#4和slot#9发起随机接入，那么只有slot#4和slot#9对应的随机接入时机为有效随机接入时机(Valid RO)，其他时隙对应的随机接入时机为无效随机接入时机(Invalid RO)。
进一步地，如图4B所示，可以将有效随机接入时机作为第二随机接入时机，然后在有效随机接入时机上进行频域偏移，例如频域偏移为Δoffset，从而可以将偏移后得到的随机接入时机作为第一随机接入时机。其中，频域偏移可以是数值，频域偏移的单位包括但不限于资源块(Resource Block，RB)、资源元素(Resource Element，RE)、带宽(Hz、KHz、MHz、GHz等)。
第一随机接入时机可以是具有全双工能力的终端的专属随机接入时机，具有全双工能力的终端可以在第一随机接入时机上向网络设备发起随机接入，网络设备可以确定终端具有全双工能力，或者，具有全双工能力的终端也可以在第二随机接入时机上向网络设备发起随机接入，网络设备可以确定终端不具有全双工能力。而不具有全双工能力的终端则只能在第二随机接入时机上向网络设备发起随机接入，网络设备可以确定终端不具有全双工能力。
在一个实施例中，所述频域偏移基于所述网络设备发送的指示信息确定，和/或，所述频域偏移基于协议约定确定。
在一个实施例中，所述第一随机接入时机为根据第一随机接入信道配置确定的随机接入时机；和/或，所述第二随机接入时机为根据第二随机接入信道配置确定的随机接入时机。
在一个实施例中，网络设备可以通过广播信令广播多个随机接入信道配置，并且可以指示每个随机接入信道配置的适用范围。例如广播第一随机接入信道配置和第二随机接入信道配置，并指示第一随机接入信道配置适用于具有全双工能力的终端，第二随机接入信道配置适用于小区内所有终端(包括具有全双工能力的终端和不具有全双工能力的终端)。
由于第一随机接入信道配置所配置的随机接入时机和第二随机接入信道配置所配置的随机接入时机可以有所不同，因此可以确保第一随机接入时机和第二随机接入时机不同，从而确保可以通过第一随机接入时机和第二随机接入时机来区分终端是否具有全双工能力。
进而具有全双工能力的终端在进行随机接入时，可以使用根据第一随机接入信道配置确定的第一随机接入时机，网络设备根据第一随机接入时机可以进行随机接入的终端具有全双工能力；不具有全双工能力的终端在进行随机接入时，可以使用根据第二随机接入信道配置确定的第二随机接入时机，网络设备根据第二随机接入时机可以进行随机接入的终端不具有全双工能力。
在一个实施例中，所述第一随机接入信道配置为全双工终端专属随机接入信道配置；和/或，所述第二随机接入信道配置为公共随机接入信道配置。
在一个实施例中，在所述第一随机接入时机与所述第二随机接入时机不重合的情况下，所述第一随机接入时机用于指示所述终端具有全双工能力；和/或在所述第一 随机接入时机与所述第二随机接入时机重合的情况下，所述第一随机接入时机用于指示所述终端不具有全双工能力。
在一个实施例中，网络设备通过第一随机接入信道配置可以配置多个第一随机接入时机，通过第二随机接入信道配置可以配置多个第二随机接入时机，多个第一随机接入时机和多个第二随机接入时机之间，可以存在不重合的随机接入时机，也可以存在重合的随机接入时机。那么在终端使用第一随机接入时机进行随机接入时，在第一随机接入时机与第二随机接入时机重合的情况下，网络设备可以确定终端不具有全双工能力，而在第一随机接入时机与第二随机接入时机不重合的情况下，网络设备才确定终端具有全双工能力。
以上实施例主要是通过随机接入过程使用的随机接入时机来区分终端是否具有全双工能力，在这种情况下，具有全双工能力的终端和不具有全双工能力的终端，可以使用具有相同索引的前导码发起随机接入，也使用具有不同索引的前导码发起随机接入，具体可以根据需要选择，本公开并不限制。
图5是根据本公开的实施例示出的一种能力确定方法的示意流程图。本实施例所示的能力确定方法可以由网络设备执行，所述网络设备可以与终端通信，所述网络设备包括但不限于4G基站、5G基站、6G基站等通信系统中的基站，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图5所示，所述能力确定方法可以包括以下步骤：
在步骤S501中，与终端进行随机接入；
在步骤S502中，根据所述终端进行随机接入所用资源确定所述终端是否具有全双工能力。
在一个实施例中，网络设备在终端需要建立通信连接时，可以与终端进行随机接入。其中，随机接入可以是四步随机接入，也可以是两步随机接入，具体可以根据需要选择，本公开并不限制。
终端在进行随机接入的过程中，可以通过随机接入所用资源隐式地向网络设备指示终端具有全双工能力，或者不具有全双工能力，其中，全双工也可以称作子带全双工SBFD。
相对应地，网络设备在与终端进行随机接入的过程中，可以根据终端进行随机接入所用资源确定终端具有全双工能力，或者不具有全双工能力，以便后续可以根据 终端的能力对终端做出适当的配置和/或调度。
在一个实施例中，网络设备在确定终端不具有全双工能力的情况下，可以不为终端配置子带。
例如在上行时域资源中不为终端配置下行子带；例如在下行时域资源中不为终端配置上行子带。据此，可以避免不具有全双工能力的终端在时域资源中尝试进行全双工通信而导致的问题，以及避免为终端配置子带而造成的频域资源浪费。
在一个实施例中，时域资源包括以下至少之一：时隙(slot)、符号(symbol)，例如符号可以是OFDM符号。
在一个实施例中，网络设备在确定终端不具有全双工能力的情况下，即便为终端配置了子带，也不调度终端在子带上进行通信。
在一个实施例中，网络设备在确定终端具有全双工能力的情况下，可以为终端配置子带。在一个实施例中，网络设备在为终端配置子带的情况下，还可以调度终端在子带上进行通信。
例如在上行时域资源中为终端配置下行子带，那么可以调度终端在上行时域资源的下行子带中进行下行通信，还可以调度终端在上行时域资源对应的下行子带以外的频域资源中进行上行通信，从而实现终端在上行时域资源内的全双工通信。
例如在下行时域资源中为终端配置上行子带，那么可以调度终端在下行时域资源的上行子带中进行上行通信，还可以调度终端在下行时域资源对应的上行子带以外的频域资源中进行下行通信，从而实现终端在下行时域资源内的全双工通信。
例如在灵活时域资源中为终端配置上行子带，那么可以调度终端在灵活时域资源的上行子带中进行上行通信，还可以调度终端在灵活时域资源对应的上行子带以外的频域资源中进行下行通信，从而实现终端在灵活时域资源内的全双工通信。
在一个实施例中，网络设备可以先为多个终端(例如同一个小区内的所有终端)配置子带。而后，根据各个终端的随机接入过程确定各个终端是否具有全双工能力。对于具有全双工能力的终端后，再调度具有全双工能力的终端在子带上进行通信，而对于不具有全双工能力的终端，则不调度在子带上进行通信。
例如在下行时域资源中为终端#1、终端#2、终端#3配置了上行子带，终端#1、终端#2、终端#3分别在随机接入过程中，通过随机接入所用资源指示了各自是否具有 全双工能力，例如终端#3具有全双工能力，终端#1、终端#2不具有全双工能力。
网络设备可以调度终端#3在下行时域资源的上行子带中进行上行通信，和/或调度终端#3在下行时域资源对应的上行子带以外的频域资源中进行下行通信，从而实现终端#3在下行时域资源内的全双工通信。基站不调度终端#1或终端#2在下行时域资源的上行子带中进行上行通信，以免终端#1和终端#2在没有全双工能力的情况下，尝试进行全双工通信而出现问题。
可见，根据本公开的实施例，网路设备可以根据终端进行随机接入所用资源确定终端是否具有全双工能力，以便网络设备根据终端的能力为终端做出适当的配置、调度。有利于确保具有全双工能力的终端能够及时受到网络设备的调度进行全双工通信，从而提高通信效率，避免不具有全双工能力的终端被网络设备调度进行全双工通信而出现问题。
需要说明的是，具有全双工能力的终端进行随机接入所用的资源，可以与不具有全双工能力的终端进行随机接入所用的资源相同，在这种情况下，网络设备认为终端不具有全双工能力。换言之，具有全双工能力的终端也可以使用与非全双工能力的终端相同的随机接入的资源，用于随机接入网络设备，在该场景下，认为具有全双工能力的终端没有上报其具有全双工能力。
在一个实施例中，所述资源包括以下至少之一：码域资源；随机接入时机。
在一个实施例中，所述码域资源包括前导码。
在一个实施例中，所述根据所述终端进行随机接入所用资源确定所述终端是否具有全双工能力，包括：在确定所述终端发送第一索引对应的前导码时，确定所述终端具有全双工能力；和/或，在确定所述终端发送第二索引对应的前导码，确定所述终端不具有全双工能力。也就是说，具有全双工能力的终端可以通过发送第二索引对应的前导码上报其不具有全双工能力，或者不启动全双工功能。
在一个实施例中，在随机接入过程中，网络设备可以接收终端发送的前导码，而前导码可以具有索引(index)，网络设备可以根据不同索引的前导码，确定终端的全双工能力。例如在接收到第一索引对应的前导码时，可以确定终端具有全双工能力，或者启动终端的全双工功能，进而可以在为终端配置的子带内调度终端进行通信；例如在接收到第二索引对应的前导码时，可以确定终端不具有全双工能力，或者不启动终端的全双工功能，那么可以不在为终端配置的子带内调度终端进行通信。
在一个实施例中，网络设备可以通过广播信令向终端发送公共随机接入信道配置(RACH-ConfigCommon)，所述广播信令包括但不限于：系统信息块(SIB)，例如SIB1；其他系统信息(OSI)。
其中，公共随机接入信道配置中的配置包括但不限于：随机接入时机(RO)、随机接入时机与同步信号块(SSB)的映射关系、前导码的总数目等。公共随机接入信道配置中的配置可以适用于多个终端(例如一个小区的所有终端)，包括具有全双工能力的终端和不具有全双工能力的终端。换言之，这多个终端都可以使用公共随机接入信道配置中的配置进行随机接入。
在一个实施例中，所述方法还包括：向所述终端发送第一指示信息，其中，所述第一指示信息用于指示所述第一索引的范围。
在一个实施例中，网络设备可以在广播信令中携带第一指示信息，第一指示信息用于指示第一索引的范围，第一索引为具有全双工能力的终端进行随机接入时需要使用的前导码的索引。其中，需要使用的前导码属于公共随机接入信道配置所配置的前导码。例如可以指示起始索引index S和结束索引index E，进而具有全双工能力的终端在进行随机接入时，可以选择index S至index E之间的索引对应的前导码发送至网络设备，用于指示其具有全双工能力的。而不具有全双工能力的终端在进行随机接入时，可以选择index S至index E之外的索引对应的前导码发送至网络设备，用于指示其不具有全双工能力。或者，具有全双工能力的终端在进行随机接入时，也可以选择index S至index E之外的索引对应的前导码发送至网络设备，用于指示其不具有全双工能力，或者不启动其全双工功能。
网络设备在接收到终端发送的前导码后，在确定前导码的索引处于index S至index E之间时，可以确定终端具有全双工能力，在确定前导码的索引处于index S至index E之外时，可以确定终端部具有全双工能力。
例如公共随机接入信道配置所配置的前导码包括56个前导码，索引从0至55，分别为preamble#0至preamble#55。网络设备通过第一指示信息可以指示索引范围0至9对应的前导码为具有全双工能力的终端进行随机接入时需要使用的前导码。
具有全双工能力的终端在进行随机接入时，可以使用preamble#0至preamble#9中任一个preamble，从而网络设备在终端发送的前导码的索引处于0至9之间时，可以确定终端具有全双工能力。而不具有全双工能力的终端在进行随机接入时，可以使 用preamble#10-preamble#55中任一个preamble，从而网络设备在终端发送的前导码的索引处于10至55之间时，可以确定终端不具有全双工能力。
在一个实施例中，所述方法还包括：向所述终端发送第二指示信息，其中，所述第二指示信息用于指示具有全双工能力的终端进行随机接入时需要使用的前导码。
在一个实施例中，网络设备可以在广播信令中携带第二指示信息，第二指示信息用于指示具有全双工能力的终端进行随机接入时需要使用的前导码，其中，需要使用的前导码不属于公共随机接入信道配置所配置的前导码。例如公共随机接入信道配置所配置的前导码为preamble#0至preamble#55，网络设备可以通过第二指示信息额外指示56至63对应的前导码preamble#56-preamble#63，并指示前导码preamble#56-preamble#63供具有全双工的终端发起随机接入使用。
具有全双工能力的终端在进行随机接入时，可以使用preamble#56-preamble#63中任一个preamble，从而网络设备在终端发送的前导码的索引处于56至63之间时，可以确定终端具有全双工能力。而不具有全双工能力的终端在进行随机接入时，可以使用公共随机接入信道配置所配置的前导码，例如使用preamble#0-preamble#55中任一个preamble，从而网络设备在终端发送的前导码的索引处于0至55之间时，可以确定终端不具有全双工能力。或者，具有全双工能力的终端在进行随机接入时，也可以使用公共随机接入信道配置所配置的前导码，例如使用preamble#0-preamble#55中任一个preamble，从而网络设备在终端发送的前导码的索引处于0至55之间时，可以认为终端不具有全双工能力，或者不启动全双工功能。
以上实施例主要是通过随机接入过程中发送的前导码的索引来区分终端是否具有全双工能力，在这种情况下，具有全双工能力的终端和不具有全双工能力的终端，可以在相同的随机接入时机上发起随机接入，也可以在不同的随机接入时机上发起随机接入，具体可以根据需要选择，本公开并不限制。
在一个实施例中，所述根据所述终端进行随机接入所用资源确定所述终端是否具有全双工能力，包括：在确定所述终端在第一随机接入时机发起随机接入时，确定所述终端具有全双工能力；或者，在确定所述终端在第二随机接入时机发起随机接入时，确定所述终端不具有全双工能力。
在一个实施例中，网络设备通过公共随机接入信道配置，可以为终端配置多个随机接入时机，网络设备可以根据终端进行随机接入所使用的随机接入时机对终端的 全双工能力进行区分。例如在确定终端通过第一随机接入时机发起随机接入时，可以确定终端具有全双工能力，进而可以在为终端配置的子带内调度终端进行通信；例如在确定终端通过第二随机接入时机发起随机接入时，可以确定终端不具有全双工能力那么可以不在为终端配置的子带内调度终端进行通信。
在一个实施例中，网络设备可以通过广播信令向终端发送公共随机接入信道配置，所述广播信令包括但不限于：系统信息块，例如SIB1；其他系统信息。
其中，公共随机接入信道配置中的配置包括但不限于：随机接入时机、随机接入时机与同步信号块的映射关系、前导码的总数目等。公共随机接入信道配置中的配置可以适用于所有终端，也即具有全双工能力的终端和不具有全双工能力的终端，都可以使用公共随机接入信道配置中的配置进行随机接入。
在一个实施例中，所述第一随机接入时机为根据公共随机接入信道配置确定的随机接入时机；和/或，所述第二随机接入时机为根据公共随机接入信道配置确定的随机接入时机。
在一个实施例中，所述方法还包括：向所述终端发送第三指示信息，其中，所述第三指示信息用于指示具有全双工能力的终端进行随机接入时需要使用的随机接入时机，和/或，不具有全双工能力的终端进行随机接入时需要使用的随机接入时机。
在一个实施例中，网络设备可以在广播信令中携带第三指示信息，第三指示信息用于指示具有全双工能力的终端进行随机接入时需要使用的随机接入时机，和/或，用于指示不具有全双工能力的终端进行随机接入时需要使用的随机接入时机，其中，具有全双工能力的终端进行随机接入时需要使用的随机接入时机和/或不具有全双工能力的终端进行随机接入时需要使用的随机接入时机可以属于公共随机接入信道配置所配置的随机接入时机。例如可以在公共随机接入信道配置所配置的多个随机接入时机RO#1至RO#10中指示RO#1，进而具有全双工能力的终端可以在RO#1上进行随机接入；而不具有全双工能力的终端可以在RO#2至RO#9中任一RO上进行随机接入。
网络设备在与终端进行随机接入时，在确定终端使用的随机接入机会为RO#1时，可以确定终端具有全双工能力，在确定终端使用的随机接入机会为RO#2至RO#9中任一RO时，可以确定终端不具有全双工能力。
在一个实施例中，所述第二随机接入时机为根据公共随机接入信道配置确定的随机接入时机；和/或，所述第一随机接入时机为根据所述第二随机接入时机和频域偏 移确定的随机接入时机。
在一个实施例中，第一随机接入时机可以是对第二随机接入时机进行频域偏移确定的，例如在第二随机接入时机的基础上加上频域偏移得到第一随机接入时机。在这种情况下，具有全双工能力的终端进行随机接入时，就可以不使用公共随机接入信道配置所配置的机接入时机了，从而不会占用不具有全双工能力的终端进行随机接入时所能使用的随机接入时机，那么不具有全双工能力的终端在进行随机接入时，能够使用公共随机接入信道配置所配置的任一随机接入时机了。
如图4A所示，例如网络设备通过公共随机接入信道配置中的随机接入信道配置的索引(RACH configuration index)等于27，该配置中随机接入时机可以分布在多个时隙(slot)中，每个时隙中存在一个随机接入时机。
例如网络设备通过时分双工上下行配置(TDD UL-DL configuration)指示的TDD结构为DDDSUDDDSU。其中，“D”表示DL slot，“S”表示flexible slot，“U”表示UL slot。也即slot#0至slot#2和slot#5至slot#7位下行时隙，slot#3和slot#8为灵活(flexible)时隙，slot#4和slot#9为上行时隙。
据此可以确定终端只能在slot#4和slot#9进行上行通信，因此只能在slot#4和slot#9发起随机接入，那么只有slot#4和slot#9对应的随机接入时机为有效随机接入时机(Valid RO)，其他时隙对应的随机接入时机为无效随机接入时机(Invalid RO)。
进一步地，如图4B所示，可以将有效随机接入时机作为第二随机接入时机，然后在有效随机接入时机上进行频域偏移，例如频域偏移为Δoffset，从而可以将偏移后得到的随机接入时机作为第一随机接入时机。其中，频域偏移可以是数值，频域偏移的单位包括但不限于资源块(RB)、资源元素(RE)、带宽(Hz、KHz、MHz、GHz等)。
第一随机接入时机可以是具有全双工能力的终端的专属随机接入时机，具有全双工能力的终端可以在第一随机接入时机上向网络设备发起随机接入，网络设备可以确定终端具有全双工能力，或者，具有全双工能力的终端也可以在第二随机接入时机上向网络设备发起随机接入，网络设备可以确定终端不具有全双工能力。而不具有全双工能力的终端则只能在第二随机接入时机上向网络设备发起随机接入，网络设备可以确定终端不具有全双工能力。
在一个实施例中，所述方法还包括：确定所述频域偏移，通过指示信息向所述 终端指示所述频域偏移；和/或，基于协议约定确定所述频域偏移。
在一个实施例中，所述第一随机接入时机为根据第一随机接入信道配置确定的随机接入时机；和/或，所述第二随机接入时机为根据第二随机接入信道配置确定的随机接入时机。
在一个实施例中，网络设备可以通过广播信令广播多个随机接入信道配置，并且可以指示每个随机接入信道配置的适用范围。例如广播第一随机接入信道配置和第二随机接入信道配置，并指示第一随机接入信道配置适用于小区内所有终端(包括具有全双工能力的终端和不具有全双工能力的终端)。
由于第一随机接入信道配置所配置的随机接入时机和第二随机接入信道配置所配置的随机接入时机可以有所不同，因此可以确保第一随机接入时机和第二随机接入时机不同，从而确保可以通过第一随机接入时机和第二随机接入时机来区分终端是否具有全双工能力。
进而具有全双工能力的终端在进行随机接入时，可以使用根据第一随机接入信道配置确定的第一随机接入时机，网络设备根据第一随机接入时机可以进行随机接入的终端具有全双工能力；不具有全双工能力的终端在进行随机接入时，可以使用根据第二随机接入信道配置确定的第二随机接入时机，网络设备根据第二随机接入时机可以进行随机接入的终端不具有全双工能力。
在一个实施例中，所述第一随机接入信道配置为全双工终端专属随机接入信道配置；和/或，所述第二随机接入信道配置为公共随机接入信道配置。
在一个实施例中，所述根据所述终端进行随机接入所用资源确定所述终端是否具有全双工能力，还包括：
在所述第一随机接入时机与所述第二随机接入时机不重合的情况下，确定所述终端具有全双工能力；和/或在所述第一随机接入时机与所述第二随机接入时机重合的情况下，确定所述终端不具有全双工能力。
在一个实施例中，网络设备通过第一随机接入信道配置可以配置多个第一随机接入时机，通过第二随机接入信道配置可以配置多个第二随机接入时机，多个第一随机接入时机和多个第二随机接入时机之间，可以存在不重合的随机接入时机，也可以存在重合的随机接入时机。那么在终端使用第一随机接入时机进行随机接入时，在第一随机接入时机与第二随机接入时机重合的情况下，网络设备可以确定终端不具有全 双工能力，而在第一随机接入时机与第二随机接入时机不重合的情况下，网络设备才确定终端具有全双工能力。
以上实施例主要是通过随机接入过程使用的随机接入时机来区分终端是否具有全双工能力，在这种情况下，具有全双工能力的终端和不具有全双工能力的终端，可以使用具有相同索引的前导码发起随机接入，也使用具有不同索引的前导码发起随机接入，具体可以根据需要选择，本公开并不限制。
图6是根据本公开的实施例示出的一种终端与网络设备的交互示意图。
如图6所示，终端在需要与网络设备建立通信连接时，可以向网络设备发起随机接入，并通过随机接入所用资源隐式指示终端是否具有全双工能力。例如，终端可以通过随机接入所用的前导码、随机接入时机等指示终端是否具有全双工能力。
相对应地，网路设备根据终端进行随机接入所用资源，可以确定终端是否具有全双功能能力，以便可以对终端进行适当的配置、调度。例如在确定终端具有全双工能力的情况下，可以在为终端配置的子带内调度终端进行通信，而在确定终端不具有全双工能力的情况下，则不在为终端配置的子带内调度终端进行通信。
在一个实施例中，终端可以向网络设备发送前导码，其中，前导码的索引用于指示终端是否具有全双工能力。
例如终端可以通过不同索引的前导码，对终端的全双工能力形成区别指示。例如通过第一索引对应的前导码，可以指示终端具有全双工能力，或者启动终端的全双工功能；例如通过第二索引对应的前导码，可以指示终端不具有全双工能力，或者不启动终端的全双工功能。
相对应地，网络设备在接收到终端发送的前导码后，可以确定前导码的索引，进而根据前导码的索引确定终端是否具有全双工能力。例如在确定前导码的索引为第一索引时，可以确定终端具有全双工能力，进而可以在为终端配置的子带内调度终端进行通信；例如在确定前导码的索引为第二索引时，可以确定终端不具有全双工能力，那么可以不在为终端配置的子带内调度终端进行通信。
在一个实施例中，终端可以向终端发起随机接入，其中，随机接入所用的随机接入时机用于指示终端是否具有全双工能力。
例如终端可以通过不同的随机接入时机对终端的全双工能力形成区别指示。例如在第一随机接入时机向网络设备发起随机接入时，可以指示终端具有全双工能力； 例如在第二随机接入时机向网络设备发起随机接入时，可以指示终端不具有全双工能力。
相对应地，网络设备与终端进行随机接入时，可以确定终端进行随机接入所使用的随机接入时机，进而根据随机接入时机确定终端是否具有全双工能力。例如在确定终端在第一随机接入时机进行随机接入时，可以确定终端具有全双工能力，进而可以在为终端配置的子带内调度终端进行通信；例如在确定终端在第二随机接入时机进行随机接入时，可以确定终端不具有全双工能力，那么可以不在为终端配置的子带内调度终端进行通信。
在一个实施例中，第一随机接入时机为根据公共随机接入信道配置确定的随机接入时机；和/或，第二随机接入时机为根据公共随机接入信道配置确定的随机接入时机。
例如，网络设备可以在广播信令中携带第三指示信息，第三指示信息用于指示具有全双工能力的终端进行随机接入时需要使用的随机接入时机，和/或，用于指示不具有全双工能力的终端进行随机接入时需要使用的随机接入时机，其中，具有全双工能力的终端进行随机接入时需要使用的随机接入时机和不具有全双工能力的终端进行随机接入时需要使用的随机接入时机可以都属于公共随机接入信道配置所配置的随机接入时机。
在一个实施例中，第二随机接入时机为根据公共随机接入信道配置确定的随机接入时机；和/或，第一随机接入时机为根据所述第二随机接入时机和频域偏移确定的随机接入时机。
例如，具有全双工能力的终端在根据公共随机接入信道配置确定第二随机接入时机后，可以根据第二随机接入时机和频域偏移(offset)确定的第一随机接入时机，例如在第二随机接入时机的基础上加上频域偏移得到第一随机接入时机。
在一个实施例中，所述第一随机接入时机为根据第一随机接入信道配置确定的随机接入时机；和/或，所述第二随机接入时机为根据第二随机接入信道配置确定的随机接入时机。
例如，网络设备可以通过广播信令广播多个随机接入信道配置，并且可以指示每个随机接入信道配置的适用范围。例如广播第一随机接入信道配置和第二随机接入信道配置，并指示第一随机接入信道配置适用于具有全双工能力的终端，第二随机接 入信道配置适用于小区内所有终端(包括具有全双工能力的终端和不具有全双工能力的终端)。
需要说明的是，本实施例涉及的其他内容请参考前文各个实施例中相关内容的描述，这里不再赘述。
