一种资源指示方法及装置
相关申请的交叉引用
本申请要求在2021年05月10日提交中国专利局、申请号为202110506625.5、申请名称为“一种资源指示方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种资源指示方法及装置。
背景技术
在新空口(new radio，NR)系统等通信系统中，终端设备通过随机接入过程与网络设备建立连接。以四步随机接入过程为例，一般涉及到以下过程：终端设备发送前导码(preamble)；网络设备发送随机接入响应(random access response，RAR)消息；终端设备发送消息3；网络设备发送竞争解决消息。
在随机接入过程中，网络设备可以通过资源指示值(resource indication value,RIV)向终端设备指示需要发送或接收的消息的资源的起始资源块(resource block，RB)和包括的RB数。例如，可以通过RIV指示消息3对应的资源的起始RB和包括的RB数。而RIV的具体取值，是根据网络设备为终端设备配置的初始(initial)上行(uplink，UL)带宽部分(bandwidth part，BWP)确定的。
然而，NR系统等通信系统中，除了支持传统(legacy)终端设备以外，还支持比传统终端设备的能力低的终端设备，即低能力(reduced capability，REDCAP)终端设备。REDCAP终端设备主要特征是终端能力的降低或受限，例如，带宽能力受限，相比于传统终端设备，最大信道带宽将降低至20MHz。对于REDCAP终端设备，上行信道带宽可能会被网络设备限制在其带宽能力之内，例如网络设备只给REDCAP终端设备配置20MHz的初始上行BWP。
由于在随机接入过程中，网络设备无法通过终端设备发送的消息识别终端设备的类型，因此网络设备会认为终端设备的类型为传统终端设备，从而按照传统终端设备的初始上行BWP确定RIV。对于REDCAP终端设备来说，其初始上行BWP的带宽大小和传统终端设备的带宽大小不同，起始位置也可能不同，因此REDCAP终端设备根据RIV确定的起始RB和RB数，与网络设备通过RIV实际指示的起始RB和RB数不同，导致随机接入失败。
综上所述，终端设备如何根据RIV确定网络设备实际起始RB和RB数，是一个亟待解决的问题。
发明内容
本申请提供一种资源指示方法及装置，用以对齐终端设备和网络设备对RIV的理解，准确获得RIV指示的资源。
第一方面，本申请提供一种资源指示方法，该方法适用于第一类型终端设备和第二类型终端设备在网络中共存的场景。该方法的执行主体为终端设备或终端设备中的芯片或一个模块，这里以终端设备为执行主体为例进行描述。该方法包括：终端设备获取来自网络设备的资源指示值，资源指示值与M、S、和L关联，其中M是第一带宽包含的资源块数，S用于确定第一传输资源的起始资源块的索引，L是第一传输资源的资源块长度；根据资源指示值和解析方式，确定S和/或资源块长度L；解析方式用于从资源指示值解析出S和/或L；根据S和/或L在第一传输资源中进行传输；其中，L的最大值为第一阈值；或，L的最大值与M有关，且L的最大值不超过N，N是终端设备支持的最大信道带宽对应的资源块个数；或，L的最大值不超过N，且解析方式与M有关；其中，终端设备是第一类型终端设备，第一带宽是第二类型终端设备工作的信道带宽，第二类型终端设备支持的最大信道带宽大于第一类型终端设备支持的最大信道带宽。
通过本申请实施例提供的方法，网络设备可以不区分终端设备的类型，统一按照相同的方法确定用于指示资源的起始RB和RB数的资源指示值。对于终端设备，获取到资源指示值时，可以通过预设的解析方式确定S和/或资源块长度L，从而根据S和/或资源块长度L确定资源指示值对应的第一传输资源。其中，在L的最大值为第一阈值，或L的最大值与M有关时，通过限制资源分配的RB数L的最大值，可以简化资源分配的复杂度。在不限制L的最大值时，L的最大值不超过N，此时可以存在多种解析方式，且解析方式与M有关，这样可以提高资源分配的灵活性，可以保证终端设备能够一次就可以获得足够的资源，从而完成数据传输，降低数据时延。
在一种可能的实现方式中，第一传输资源的起始资源块的索引为S；或者，第一传输资源的起始资源块的索引为S1，S1根据S和第一偏移参数确定。在确定网络设备为其分配的资源的起始资源块的索引时，考虑第一带宽和第二带宽的起始RB在频率上是否对齐的情况，在对齐的情况下，第一传输资源的起始资源块的索引为S；在不对齐的情况下，第一传输资源的起始资源块的索引为S1，使得本申请方案能够适用于所有的场景。
在一种可能的实现方式中，第一阈值根据M和N中的至少一项确定。
在一种可能的实现方式中，L的最大值与M有关，包括：M属于第一数值范围时，L的最大值等于Lmax1；或者，M属于第二数值范围时，L的最大值等于Lmax2；其中，Lmax2小于Lmax1。通过建立L的最大值与M的对应关系，简化终端设备的实现，降低终端设备的复杂度，避免无法根据由M确定的资源指示值，获取到该资源指示值指示的L的情况。
在一种可能的实现方式中，解析方式与M有关，包括：M属于第一数值范围，按照第一解析方式确定S和/或L；M属于第二数值范围，按照第二解析方式确定S和/或L；其中，第一解析方式和第二解析方式是不同的解析方式。解析方式与M有关，可以实现在M属于不同数值范围时，按照不种解析方式解析资源指示值，这样可以提高资源分配的灵活性。
在一种可能的实现方式中，M属于第一数值范围，包括：M大于或等于第一参数的值；或者，M属于第二数值范围，包括：M小于第一参数的值。第一参数可以根据N确定，例如第一参数可以是2N-2，或是2N，或是2N-1等。
在一种可能的实现方式中，第一解析方式包括：S、M和资源指示值满足第一关系，L、M和资源指示值满足第二关系；和/或，第二解析方式包括：若L小于或等于第二阈值，S、 M和资源指示值满足第一关系，L、M和资源指示值满足第二关系；若L大于第二阈值，S、M和资源指示值满足第三关系，L、M和资源指示值满足第四关系。
在一种可能的实现方式中，资源指示值承载于随机接入响应消息或下行控制信息。此时，资源指示值可以用于指示承载消息3的资源，从而使得第一类型终端设备能够成功完成随机接入过程。
在一种可能的实现方式中，根据S和/或L在第一传输资源中进行传输，包括：通过第一传输资源向网络设备发送随机接入过程中的消息3；或者，通过第一传输资源向网络设备发送物理上行共享信道；或者，通过第一传输资源接收来自网络设备的物理下行共享信道。
在一种可能的实现方式中，终端设备还可以获取M，第一带宽的起始资源块的索引，第二带宽的起始资源块的索引和N中的至少一项，其中第二带宽是第一类型终端设备工作的信道带宽。

在一种可能的实现方式中，该通信装置包括：处理器，该处理器被配置为支持该通信装置执行以上所示方法中终端设备的相应功能。该通信装置还可以包括存储器，该存储可以与处理器耦合，其保存该通信装置必要的程序指令和数据。可选地，该通信装置还包括接口电路，该接口电路用于支持该通信装置与网络设备等设备之间的通信。

为了实现终端设备与网络设备之间的数据传输，终端设备需要初始接入(initial access)网络设备，并通过随机接入过程建立与网络设备的无线连接。以NR系统为例，如图2所示，为一种终端设备初始接入过程的流程示意图，具体可以包括以下步骤。
步骤一：终端设备获取网络设备广播的同步信号块/同步信号广播信道块(synchronous signal/physical broadcast channel block，SS/PBCH block，SSB)。
其中，SSB可以包括主同步信号(primary synchronisation signal，PSS)、辅同步信号(secondary synchronisation signal，SSS)和物理广播信道(physical broadcast channel，PBCH)中至少一项。如图3所示，在时域上，1个SSB占用4个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号(symbol)，记为符号0～符号3，在频域上，1个SSB占用20个资源块(resource block，RB)(一个RB包括12个子载波)，也就是240个子载波，子载波编号为0～239。PSS位于符号0的中间的127个子载波上，SSS位于符号2的中间的127个子载波上。为了保护PSS和SSS，分别有各自的保护子载波。保护子载波不用于承载信号，在PSS和SSS两侧分别留有子载波作为保护子载波，如图3中的SSS两 侧的空白区域就是保护子载波。PBCH占用符号1和符号3的全部子载波，以及占用符号2的全部子载波中除了SSS所占用的子载波之外的剩余的子载波中的一部分子载波(即剩余的子载波中除了保护子载波之外的子载波)。为了描述方便，后面的描述中，将OFDM符号简称为符号。
步骤二：终端设备从SSB中的PBCH中获取主系统信息块(master information block，MIB)。
终端设备根据MIB确定公共搜索空间(common search space，CSS)，以及确定控制资源集合(control resource set，CORESET)#0。NR系统中，CORESET#0的带宽即为初始下行带宽部分(bandwidth part，BWP)的带宽。
步骤三：终端设备从CORESET#0和CSS中盲检测系统信息无线网络临时标识(system information radio network temporary indicator，SI-RNTI)加扰的下行控制信息(downlink control information，DCI)。
步骤四：终端设备根据DCI的指示，获取系统信息，例如系统信息块1(system information block 1，SIB1)。
终端设备从SIB1中可以获得上行初始BWP的配置信息，以及随机接入资源的配置信息、寻呼资源的配置信息等。上行BWP的频率范围由SIB指定，带宽不超过传统终端设备的带宽能力。在FDD系统中，由于上下行传输工作在不同的频段，上行初始BWP和下行初始BWP在不同的频段；在TDD系统中，上下行BWP的中心频点对齐，带宽可以不一致。除了上下行初始BWP资源外，SIB1中还指示了用于终端设备进行随机接入的物理随机接入信道(physical random access channel，PRACH)等资源。
终端设备可以通过SIB1指示的PRACH资源进行随机接入过程。示例性地，如图4所示，为现有的一种随机接入过程示意图。
S401，终端设备通过PRACH向网络设备发送前导码(preamble)。
其中，前导码也可以称为随机接入过程的消息1。
示例性地，前导码可以是一个序列，其作用是通知网络设备有一个随机接入请求，并使得网络设备能估计终端设备与网络设备之间的传输时延，以便网络设备校准该终端设备的上行定时(uplink timing)，并将校准信息通过定时提前(timing advance，TA)指令告知终端设备。
S402，网络设备向终端设备发送随机接入响应(random access response，RAR)。
RAR也称为消息2，RAR中可包含接收到的前导码的标识，定时提前(timing advance,TA)，上行授权(uplink grant，UL grant)和临时小区无线网络临时标识(temporary cell radio network temporary identifier，TC-RNTI)。其中，TA用于终端设备进行上行定时调整，以保证上行同步。UL grant可以指示用于传输消息3的物理上行共享信道(physical uplink shared channel，PUSCH)的资源位置。
S403，终端设备通过消息2指示的资源位置向网络设备发送消息3。
S404，网络设备接收消息3，并向接入成功的终端设备发送冲突解决(contention resolution)消息。
冲突解决消息也可以称为消息4。用于调度消息4的下行控制信息(downlink control information，DCI)用RAR中携带的TC-RNTI加扰，网络设备可以通过消息4对终端设备进行RRC配置。
在NR协议中，PUSCH资源分配类型1(type1)和物理下行共享信道(physical downlink shared channel，PDSCH)资源分配type1的资源分配原则如下：
1)为终端设备分配连续的资源块(resource block，RB)，分配的资源块数在终端设备工作的带宽部分(bandwidth part，BWP)的总RB数的范围内；
2)通过RIV指示资源的起始RB的索引和资源块长度(即连续分配的RB数)，RIV取值的确定方式如下：
如果满足
Figure PCTCN2022091779-appb-000001
则
Figure PCTCN2022091779-appb-000002
如果
Figure PCTCN2022091779-appb-000003
则
Figure PCTCN2022091779-appb-000004
其中，
Figure PCTCN2022091779-appb-000005
是终端设备工作的BWP的总RB数，RB start是起始RB的索引，L RBs是资源块长度，
Figure PCTCN2022091779-appb-000006
是向下取值运算。
从以上公式可以看出，RIV的取值和总RB数、起始RB的索引以及资源块长度相关。目前，在REDCAP终端设备和传统终端设备共存的场景下，如果网络设备无法识别终端设备的类型，默认该终端设备为传统终端设备，因此向该终端设备发送的RIV的取值，是根据传统终端设备工作的BWP的总RB数确定的，这样会导致REDCAP终端设备无法根据RIV确定网络设备实际指示的起始RB和RB数。
举例来说，以上述随机接入过程为例，假如没有为REDCAP终端设备分配专属的PRACH机会(PRACH occasion，RO)且没有为REDCAP终端设备分配专属的前导码，那么网络设备无法通过前导码区分终端设备的类型。网络设备为传统终端设备和REDCAP终端设备分别配置的BWP可以如图5或图6所示。图5中，以传统终端设备工作的BWP的起始RB与REDCAP终端设备工作的BWP的起始RB在频率上对齐为例；图6中，以传统终端设备工作的BWP的起始RB与REDCAP终端设备工作的BWP的起始RB在频率上不对齐为例。图5和图6中，传统终端设备工作的BWP的总RB数大于REDCAP终端设备工作的BWP的总RB数。
结合上面的描述，由于网络设备无法区分终端设备的类型，网络设备发送的消息3中的UL grant包括的RIV，是按照传统终端设备工作的BWP的总RB数确定的。如果发起随机接入的终端设备为REDCAP终端设备，由于REDCAP终端设备工作的BWP的总RB数与传统终端设备工作的BWP的总RB数不相同，REDCAP终端设备无法准确根据UL grant中的RIV确定用于传输消息3的资源位置。例如，如图5所示，网络设备通过RIV指示的资源位置为位置1，但是终端设备根据RIV确定的资源位置可能位于位置2。示例地，若是网络设备无法通过前导码(或随机接入时机)区分终端设备的类型，则RedCap UE接收的RAR的资源分配，RedCap UE发送的消息3的资源分配，RedCap UE接收的消息4中的一项或多项是按照传统终端设备的RIV值指示的；若网络设备在连接态的终端设备能力上报才区分终端设备的类型，则RedCap UE接收的RAR的资源分配，RedCap UE发送的消息3的资源分配，RedCap UE接收的消息4，RedCap UE发送的物理上行共享信道的资源分配，RedCap UE接收的物理下行共享信道的资源分配中的一项或多项是按照传统终端设备的RIV值指示的。
为此，本申请提供一种方法，用于对齐终端设备和网络设备对RIV的理解，使得终端设备能够准确的确定RIV指示的资源。本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的 限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请中，以网络设备与终端设备之间交互为例进行说明，网络设备执行的操作也可以由网络设备内部的芯片或模块执行，终端设备执行的操作也可以由终端设备内部的芯片或模块执行。如图7所示，为本申请实施例提供的一种资源指示方法流程示意图。该方法包括：
S701：网络设备根据M、S、和L确定资源指示值。
其中，M，N，和L都是整数；M是第一带宽包含的资源块数，也可以理解为第一带宽包含的资源块总数，第一带宽是第二类型终端设备工作的信道带宽；S用于确定第一传输资源的起始资源块的索引，具体可以用于确定第一传输资源的起始资源块在第二带宽中的索引，S可以是指第一传输资源的起始资源块在第一带宽中的索引。第二带宽是第一类型终端设备工作的信道带宽。由于第一带宽的起始资源块和第二带宽的起始资源块的位置可能不同，因此第一传输资源的起始资源块在第一带宽中的索引和第一传输资源的起始资源块在第二带宽中的索引可能相同，也可能不同。
L是第一传输资源的资源块长度，即第一传输资源包括的资源块数量，第一传输资源是网络设备为终端设备分配的资源。
本申请实施例中，网络设备在确定资源指示值时，不管是对于第一类型终端设备还是第二类型终端设备，都使用相同的RIV编号规则，即都按照M个RB确定RIV。
S702：网络设备向终端设备发送资源指示值。
网络设备具体如何发送资源指示值，可能存在多种实现方式。一种可能的实现方式中，网络设备通过下行控制信息向终端设备发送资源指示值；另一种可能的实现方式中，当本申请实施例应用于随机接入过程中时，网络设备可以通过资源指示值向终端设备指示用于承载随机接入过程中的消息3的资源，在该实现方式中，网络设备可以通过随机接入响应消息发送资源指示值。
S703：终端设备获取来自网络设备的资源指示值。
本申请实施例中，终端设备还可以获取M，第一带宽的起始资源块的索引，第二带宽的起始资源块的索引和N中的至少一项，N是第一类型终端设备支持的最大信道带宽对应的资源块个数，N是第一类型终端设备支持的最大信道带宽对应的资源块总数或者，N是第一类型终端设备工作的信道带宽对应的资源块个数，也可以理解为N是第一类型终端设备工作的信道带宽对应的资源块总数，且第一类型终端设备工作的信道带宽不超过第一类型终端设备支持的最大信道带宽，M和N均为大于0的整数，M大于N。第一类型终端设备工作的信道带宽为第一类型终端设备工作的初始上行带宽部分，或初始下行带宽部分，或上行带宽部分，或下行带宽部分。网络设备可以通过系统信息广播M和N，相应的，终端设备可以通过系统信息获取M和N，例如，系统信息可以是MIB，或是SIB1，或是SIB1中的字段，或是调度承载SIB1的PDSCH的DCI，或是调度承载SIB1的PDSCH的DCI中的字段。
本申请实施例中，第二类型终端设备支持的最大信道带宽大于第一类型终端设备支持的最大信道带宽，例如第二类型终端设备支持的最大信道带宽为100MHz，第一类型终端设备支持的最大信道带宽为20MHz，或为10MHz，或为5MHz。
S704：终端设备根据资源指示值和解析方式确定S和/或L，并根据S和/或L在第一 传输资源中进行传输。
其中，解析方式用于从资源指示值解析出S和/或L，解析方式可以是公式，或是表格，或是函数等，具体实现方式将在后面进行详细描述。终端设备根据资源指示值和解析方式确定S和/或L，并根据S和/或L在第一传输资源中进行传输，传输可以是发送或接收，即：终端设备根据资源指示值和解析方式确定S和/或L，并根据S和/或L在第一传输资源中发送物理上行共享信道，或者，终端设备根据资源指示值和解析方式确定S和/或L，并根据S和/或L在第一传输资源中接收物理下行共享信道。
本申请实施例中，网络设备具体如何确定资源指示值，相应的，终端设备如何根据资源指示值确定S和/或L，可能存在多种实现方式，下面分别进行描述。
需要说明的是，本申请实施例可以适用于以下两种情况，情况一，终端设备工作的信道带宽(以下均称为第二带宽)的起始资源块与第二类型终端设备工作的信道带宽(以下均称为第一带宽)的起始资源块在频率上对齐；情况二，第二带宽的起始资源块与第一带宽的起始资源块在频率上不对齐。情况一和情况二的区别，主要在于第一传输资源的起始资源块的索引的确定方式，其它方面可相互参考。
实现方式一：
在实现方式一中，L的最大值为第一阈值，也就是说，网络设备分配给终端设备的第一传输资源包括的资源块的数量L的最大值为第一阈值，第一阈值可以小于N。其中，第一阈值可以是网络设备配置的，第一阈值还可以根据其他方式确定，例如第一阈值可以根据M和N中的至少一项确定。举例来说，第一阈值等于N/2；或者第一阈值等于M/2；或者第一阈值等于M/4+N/4。
再举例来说，第一阈值可以等于
Figure PCTCN2022091779-appb-000007
第一阈值还可以等于
Figure PCTCN2022091779-appb-000008
是或者
Figure PCTCN2022091779-appb-000009
以上只是示例，第一阈值还可以通过其他方式确定，在此不再赘述。
实现方式一中，网络设备默认终端设备的类型为第二类型，此时网络设备可以根据第二类型终端设备工作的信道带宽确定资源指示值。举例来说，网络设备为终端设备分配的第一传输资源的起始资源块的索引为ST，第一传输资源的资源长度为L时，网络设备可以通过以下方式确定资源指示值RIV：
RIV＝M(L-1)+ST          (1)
相应的，对于终端设备为第一类型终端设备时，终端设备可以按照第一解析方式确定S和/或L。本申请实施例中，第一解析方式可以包括第一关系和第二关系，其中S、M和资源指示值满足第一关系，L、M和资源指示值满足第二关系。
第一关系和第二关系的具体形式，本申请实施例并不限定，举例来说，当网络设备根据公式(1)确定资源指示值时，S可以根据M和资源指示值RIV确定，此时第一关系可以为如下形式：
S＝MOD(RIV，M)      (2)
其中，MOD表示取余运算。
当网络设备根据公式(1)确定资源指示值时，L也可以根据M和资源指示值RIV确定，此时第二关系可以为如下形式：
Figure PCTCN2022091779-appb-000010
本申请实施例中，第一解析方式包括的第一关系和第二关系，可以为协议预先约定的，也可以为网络设备指示给终端设备的。通过上面提供的第一关系和第二关系，在资源指示 值是根据第二类型终端设备工作的信道带宽包括的资源块数量M确定的情况下，使得第一类型终端设备依然能够根据该资源指示值确定网络设备为其分配的资源的起始资源块的索引以及资源块长度，实现在第一类型终端设备与第二类型终端设备共存的情况下，网络设备按照相同的方法向不同类型终端设备进行资源指示，降低网络设备资源指示的复杂度。
本申请实施例中，终端设备根据资源指示值确定L之后，可以将L作为第一传输资源的资源长度。终端设备根据资源指示值确定S之后，可以确定第一传输资源的起始资源块的索引。具体的，在情况一中，由于第一带宽的起始资源块的索引和第二带宽的起始资源块的索引相同，第一传输资源的起始资源块的索引可以等于S；在情况二中，由于第一带宽的起始资源块的索引和第二带宽的起始资源块的索引不相同，第一传输资源的起始资源块的索引可以等于S1，S1根据S和第一偏移参数确定，具体的，S1与S满足线性关系，例如S1可以满足以下公式：
S1＝A*S+P       (4)
其中，P为第一偏移参数，A为第二偏移参数，A和P可以为预定义的。例如，A＝1。
由于在情况二中，第二带宽的起始资源块与第一带宽的起始资源块在频率上不对齐，因此本申请实施例通过第一偏移参数补偿第二带宽的起始资源块与第一带宽的起始资源块在频率上的偏移，使得终端设备能够获得准确的第一传输资源。
本申请实施例中，第一偏移参数可以根据第一带宽的起始资源块的索引和第二带宽的起始资源块的索引确定，例如，如图8所示，第一带宽的起始资源块的索引为ST1，第二带宽的起始资源块的索引为ST2，第一偏移参数P可以满足以下公式：
P＝ST2-ST1(5)
第一偏移参数可以为正数，0或者负数。当第一偏移参数为0，表示第一带宽的起始资源块和第二带宽的起始资源块在频率上对齐。
本申请实施例中，第一偏移参数可以是网络设备通过高层信令指示的，例如高层信令可以为SIB1。另一种实现方式中，第一偏移参数也可以是终端设备根据第一带宽和第二带宽确定的。
示例地，通过实现方式一可知，网络设备可以通过DCI或RAR UL grant携带RIV，DCI或RAR UL grant中的频率域资源分配值字段包括RIV，该RIV对应了物理上行共享信道或物理下行共享信道的起始资源块的索引S和连续分配的资源块的个数L。对于第一类型终端设备，例如RedCap UE，该RIV指示了物理上行共享信道或物理下行共享信道的起始资源块的索引S+S1和连续分配的资源块的个数L，其中，L不超过第一阈值。
通过本申请实施例提供的方法，通过限制资源分配的RB数L的最大值，可以简化资源分配的复杂度。另外，在确定网络设备为其分配的资源的起始资源块的索引时，考虑第一带宽和第二带宽的起始RB在频率上是否对齐的情况，在不同情况下按照不同方式确定起始资源块的索引，使得本申请方案能够适用于所有的场景。通过本申请实施例提供的方法，网络设备可以不区分终端设备的类型，终端设备按照本实施例的方法确定资源分配的起始RB和RB数，有利于传统终端设备与RedCap UE在网络中的共存。
实现方式二：
在实现方式二中，网络设备可以通过公式(1)确定资源指示值RIV，具体可以参考实现方式一中的描述，在此不再赘述。
在实现方式二中，由于需要根据第一带宽包括的资源块数量M确定在第二带宽中为终 端设备分配的第一传输资源对应的资源指示值，因此M的取值大小，会影响由M确定的资源指示值指示的L的最大值。
为了实现对第一类型终端设备和第二类型终端设备都使用相同的RIV编号规则的情况下，简化终端设备的实现，降低终端设备的复杂度，可以建立L的最大值与M的对应关系，避免无法根据由M确定的资源指示值，获取到该资源指示值指示的L的情况。
在实现方式二中，L的最大值可以与M有关，另外L的最大值不超过N。也就是说，在该实现方式中，L的最大值与M存在对应关系。L的最大值与M的对应关系，可以是协议约定的，也可以是网络设备配置的，本申请实施例并不限定。
L的最大值与M的对应关系可能存在多种实现方式，例如可以建立L的最大值与M所属的数值范围的对应关系。举例来说，M属于第一数值范围时，L的最大值等于Lmax1；M属于第二数值范围时，L的最大值等于Lmax2；Lmax2可以小于Lmax1。第一数值范围与第二数值范围可以不存在交集。例如M属于第一数值范围时，表示M大于或等于第一参数的值；M属于第二数值范围时，表示M小于第一参数的值。再例如，M属于第一数值范围时，表示M大于第一参数的值；M属于第二数值范围时，表示M小于或等于第一参数的值。通过M与第一参数的关系可以确定M所属的数值范围是第一数值范围还是第二数值范围，进一步，根据M所属的数值范围来确定L的最大值，也就是说，根据第一带宽包括的资源块数量来确定资源指示值的上限，可以在保证资源指示功能的同时节省信令资源。
第一参数、Lmax1以及Lmax2的取值，可以是网络设备指示的，也可以是协议定义的。例如，第一参数可以根据N确定，例如第一参数可以是2N-2，或是2N，或是2N-1等。
Lmax1可以根据N确定，例如，Lmax1可以等于N。Lmax1还可以等于第一类型终端设备支持的最大信道带宽对应的RB数。
Lmax2可以根据M和N中的至少一项确定，例如，Lmax2等于N/2；或者Lmax2等于M/2；或者Lmax2等于M/4+N/4。再例如，Lmax2可以等于
Figure PCTCN2022091779-appb-000011
第一阈值还可以等于
Figure PCTCN2022091779-appb-000012
是或者
Figure PCTCN2022091779-appb-000013
以上只是示例，第一参数、Lmax1以及Lmax2的取值还可以通过其他方式确定，在此不再赘述。
在实现方式二中，对于终端设备为第一类型终端设备时，终端设备可以按照第一解析方式确定S和/或L。其中，第一解析方式可以包括第一关系和第二关系，第一关系和第二关系的具体形式，可以参考实现方式一中的描述，在此不再赘述。
在实现方式二中，终端设备根据资源指示值确定L之后，可以将L作为第一传输资源的资源长度。终端设备根据资源指示值确定S之后，可以确定第一传输资源的起始资源块的索引。具体的，在情况一中，第一传输资源的起始资源块的索引可以等于S；在情况二中，第一传输资源的起始资源块的索引可以等于S1，S1根据S和第一偏移参数确定，具体可以参考实现方式一中的描述，在此不再赘述。
示例地，通过实现方式二可知，网络设备可以通过DCI或RAR UL grant携带RIV，DCI或RAR UL grant中的频率域资源分配值字段包括RIV，该RIV对应了物理上行共享信道或物理下行共享信道的起始资源块的索引S和连续分配的资源块的个数L。对于第一类型终端设备，例如RedCap UE，该RIV指示了物理上行共享信道或物理下行共享信道的起始资源块的索引S+S1和连续分配的资源块的个数L；若M小于第一参数的值，则L不超过Lmax1；若M大于或等于第一参数的值，则L不超过Lmax2。
通过本申请实施例提供的方法，根据M所属的数值范围确定是否限制资源分配的RB数L的最大值。一方面可以简化资源分配的复杂度，另一方面可以避免M所属的特定的数值范围内时避免资源分配的限制。另外，在确定网络设备为其分配的资源的起始资源块的索引时，考虑第一带宽和第二带宽的起始RB在频率上是否对齐的情况，在不同情况下按照不同方式确定起始资源块的索引，使得本申请方案能够适用于所有的场景。通过本申请实施例提供的方法，网络设备没有区分终端设备的类型，终端设备按照本实施例的方法确定资源分配的起始RB和RB数，有利于传统终端设备与RedCap UE在网络中的共存。
实现方式三：
在实现方式三中，如果M属于第一数值范围，例如M大于或等于第一参数的值，网络设备可以通过公式(1)确定资源指示值RIV，公式(1)具体可以参考实现方式一中的描述，在此不再赘述。
如果M属于第二数值范围，例如M小于第一参数的值，且L小于或等于第二阈值时，网络设备可以通过公式(1)确定资源指示值RIV。这里的L也可以小于第二阈值，不等于第二阈值。
如果M属于第二数值范围，例如M小于第一参数的值，且L大于第二阈值(这里的L也可以等于第二阈值)时，网络设备可以通过以下公式确定资源指示值RIV：
RIV＝M(M-L+1)+(M-1-ST)      (6)
其中，第二阈值可以根据M确定，例如，第二阈值可以等于
Figure PCTCN2022091779-appb-000014
在实现方式三中，可以不限定L的最大值是否与M有关，此时L的取值可以由网络设备根据终端设备需要传输的数据量确定，但L的最大值不超过N。
在实现方式三中，确定S和/或L的解析方式可以与M有关，具体的，如果M属于第一数值范围，按照第一解析方式确定S和/或L；如果M属于第二数值范围，按照第二解析方式确定S和/或L。其中，第一解析方式和第二解析方式是不同的解析方式。
举例来说，如果M属于第一数值范围，例如M大于或等于第一参数的值，终端设备可以按照第一解析方式确定S和/或L。其中，第一解析方式可以包括第一关系和第二关系，当网络设备根据公式(1)确定资源指示值时，S、M和资源指示值可以满足第一关系，此时第一关系可以为如下形式：
S＝MOD(RIV，M)    (7)
其中，MOD表示取余运算。
当网络设备根据公式(1)确定资源指示值时，L、M和资源指示值满足第二关系，此时第二关系可以为如下形式：
Figure PCTCN2022091779-appb-000015
如果M属于第二数值范围，例如M小于第一参数的值，终端设备可以按照第二解析方式确定S和/或L。第二解析方式可以包括第一关系、第二关系、第三关系和第四关系。
其中，当L小于或等于第二阈值时，S、M和资源指示值可以满足第一关系，第一关系可以参考公式(7)中的描述，在此不再赘述；L、M和资源指示值满足第二关系，第二关系可以参考公式(8)中的描述，在此不再赘述。
当L大于第二阈值时，S、M和资源指示值可以满足第三关系，第三关系可以为如下形式：
S＝M-MOD(RIV，M)-1    (9)
当L大于第二阈值时，L、M和资源指示值满足第四关系，第四关系可以为如下形式：
Figure PCTCN2022091779-appb-000016
在实现方式三中，如果M属于第二数值范围，网络设备向终端设备指示S、L、M和资源指示值之间的关系，例如L小于或等于第二阈值时，网络设备可以向终端设备指示S、M和资源指示值满足第一关系，L、M和资源指示值满足第二关系；L大于第二阈值时，网络设备可以向终端设备指示S、M和资源指示值满足第三关系，L、M和资源指示值满足第四关系。
在实现方式三中，如果M属于第二数值范围，网络设备向终端设备指示L的取值范围，例如L小于或等于第二阈值时，网络设备可以向终端设备指示L小于或等于第二阈值，此时终端设备可以确定S、M和资源指示值满足第一关系，L、M和资源指示值满足第二关系；L大于第二阈值时，网络设备可以向终端设备指示L大于第二阈值，此时终端设备可以确定S、M和资源指示值满足第三关系，L、M和资源指示值满足第四关系。
在实现方式三中，网络设备也可以不向终端设备指示S、L、M和资源指示值之间的关系或者L的取值范围。终端设备可以根据第一关系和第三关系分别确定S的两个取值，根据第二关系和第四关系分别确定L的两个取值，并根据S的取值范围和L的取值范围，从中确定出S和L的正确取值。
在实现方式三中，如果M属于第二数值范围，L的最大值等于Lmax2，终端设备可以根据第一解析方式确定L和/或S。在实现方式三中，终端设备根据资源指示值确定L之后，可以将L作为第一传输资源的资源长度。终端设备根据资源指示值确定S之后，可以确定第一传输资源的起始资源块的索引。具体的，在情况一中，第一传输资源的起始资源块的索引可以等于S；在情况二中，第一传输资源的起始资源块的索引可以等于S1，S1根据S和第一偏移参数确定，具体可以参考实现方式一中的描述，在此不再赘述。
举例来说，结合前面的描述，假设第一带宽的子载波间隔和第二带宽的子载波间隔均为15kHz，第一带宽为40MHz，第二带宽为20MHz，假设第一带宽的起始资源块和第二带宽的起始资源块在频率上对齐，即第一偏移值等于0。第一带宽包括的RB数M为216；第二带宽包括的RB数N为106。L和S在不同取值的情况下，网络设备确定出的RIV的取值可以如表1所示：
表1
Figure PCTCN2022091779-appb-000017
Figure PCTCN2022091779-appb-000018
例如，结合表1，当网络设备在第二带宽中分配的资源，在第一带宽中的起始资源块索引S为0，资源长度为105时，RIV的取值为104*216。
假设第一参数的值为2N＝212，此时M大于第一参数的值，那么S、M和资源指示值可以满足第一关系，L、M和资源指示值满足第二关系。假设第一关系可以为公式(7)，第二关系可以为公式(8)，终端设备可以按照公式(7)确定S，按照公式(8)确定L。
例如，假设终端设备获取到的资源指示值RIV等于105*216，那么终端设备确定出的S和L可以为：
S＝MOD(105*216，216)＝0；

再例如，假设终端设备获取到的资源指示值RIV等于4*216+3，那么终端设备确定出的S和L可以为：
S＝MOD(4*216+3，216)＝3；
Figure PCTCN2022091779-appb-000020
根据上面的例子可知，终端设备根据第一关系确定出的S，以及根据第二关系确定出的L，和网络设备实际通过资源指示值指示的S和L均相同，因此通过本申请实施例提供的方法，可以保证网络设备和终端设备对资源指示值的理解一致，第一类型终端设备可以准确根据资源指示值确定网络设备分配的资源。
再举例来说，假设第一参数的值为2N，假设第一带宽的子载波间隔和第二带宽的子载波间隔均为15kHz，第一带宽为25MHz，第二带宽为20MHz，假设第一带宽的起始资源块和第二带宽的起始资源块在频率上对齐，即第一偏移值等于0。第一带宽包括的RB数M为133；第二带宽包括的RB数N为106。L和S在不同取值的情况下，网络设备确定出的RIV的取值可以如表2所示：
表2
Figure PCTCN2022091779-appb-000021
Figure PCTCN2022091779-appb-000022
例如，结合表2，当网络设备在第二带宽中分配的资源，在第一带宽中的起始资源块索引S为0，资源长度为68时，RIV的取值为66*133+132。
结合表2，第一参数的值为2N＝266，此时M小于第一参数的值，假设第二阈值为M/2。
那么L小于或等于第二阈值时，S、M和资源指示值可以满足第一关系，L、M和资源指示值满足第二关系。假设第一关系可以为公式(7)，第二关系可以为公式(8)，终端设备可以按照公式(7)确定S，按照公式(8)确定L。
那么L大于第二阈值时，S、M和资源指示值可以满足第三关系，L、M和资源指示值满足第四关系。假设第三关系可以为公式(9)，第四关系可以为公式(10)，终端设备可以按照公式(9)确定S，按照公式(10)确定L。
例如，假设终端设备获取到的资源指示值RIV等于4*133+3，那么根据第一关系和第二关系，终端设备确定出的S和L可以为：
S＝MOD(4*133+3，133)＝3；
Figure PCTCN2022091779-appb-000023
再例如，假设终端设备获取到的资源指示值RIV等于66*133+132，那么根据第三关系和第四关系，终端设备确定出的S和L可以为：
S＝133-MOD(66*133+132，133)-1＝0；
Figure PCTCN2022091779-appb-000024
根据上面的例子可知，终端设备根据第一关系确定出的S，以及根据第二关系确定出的L，和网络设备实际通过资源指示值指示的S和L均相同，因此通过本申请实施例提供的方法，可以保证网络设备和终端设备对资源指示值的理解一致，第一类型终端设备可以准确根据资源指示值确定网络设备分配的资源。
示例地，通过实现方式三可知，网络设备可以通过DCI或RAR UL grant携带RIV，DCI或RAR UL grant中的频率域资源分配值字段包括RIV，该RIV值对应了物理上行共享信道或物理下行共享信道的起始资源块的索引S和连续分配的资源块的个数L。对于第一类型终端设备，例如RedCap UE，该RIV指示了物理上行共享信道或物理下行共享信道的起始资源块的索引S+S1和连续分配的资源块的个数L。
在本申请实施方式中，对于第二带宽为20MHz，第一带宽大于或等于40MHz时，终端设备只需要按照第一解析方式确定S和/或L，其中，第一带宽可以是40MHz，50MHz，60MHz，70MHz，80MHz，90MHz，和100MHz；或者，对于第二带宽为20MHz在特定 子载波间隔下对应的RB时，第一带宽大于或等于40MHz在特定子载波间隔下对应的RB时，终端设备按照第一解析方式确定S和/或L，其中，第一带宽和第二带宽的子载波间隔的特定子载波间隔相同，第一带宽可以是40MHz，50MHz，60MHz，70MHz，80MHz，90MHz，和100MHz。在本实施方式中，对于第二带宽为20MHz，第一带宽为25MHz或30MHz时，终端设备按照第二解析方式确定S和/或L；或者，对于第二带宽为20MHz在特定子载波间隔下对应的RB时，第一带宽为25MHz或30MHz在特定子载波间隔下对应的RB时，终端设备按照第二解析方式确定S和/或L，其中，第一带宽和第二带宽的子载波间隔的特定子载波间隔相同。
在上述实现方式中，不需要对分配的资源的资源长度L做任何限制，可以保证终端设备能够一次就可以获得足够的资源，从而完成数据传输，降低数据时延。另外，考虑第一带宽和第二带宽的起始RB在频率上是否对齐的情况，在不同情况下按照不同方式确定起始资源块的索引，使得本申请方案能够适用于所有的场景。
本申请实施例中，终端设备可以在第一传输资源中向网络设备发送数据或消息，也可以在第一传输资源中接收来自网络设备发送数据或消息。例如，如果资源指示值通过随机接入过程中的消息2携带，那么终端设备可以通过第一传输资源向网络设备发送随机接入过程中的消息3，相应的，网络设备在所述第一传输资源中接收来自所述终端设备的随机接入过程中的消息3。例如，如果资源指示值通过下行控制信息携带，那么终端设备可以通过第一传输资源向网络设备发送物理上行共享信道，或者，通过第一传输资源接收来自网络设备的物理下行共享信道，相应的，网络设备在所述第一传输资源中接收来自所述终端设备的物理上行共享信道或者物理下行共享信道。
