首先，对本申请实施例中涉及的部分名词进行解释，以便于本领域技术人员理解。
随机接入(Random Access)：随机接入过程是指从终端设备发送随机接入前导码开始尝试接入网络到与网络设备间建立起基本的信令连接之前的过程。随机接入的类型可以划分为两步随机接入和四步随机接入。
对于四步随机接入，整个过程包含4个步骤：随机接入请求消息的传输、随机接入响应(random access response，RAR)消息的传输、消息3(Msg3)的传输和消息4(Msg4)的传输。
步骤一、随机接入请求消息的传输，即终端设备向网络设备发送随机接入请求消息。其中，随机接入请求消息，又可以称之为消息1(Msg1)。
具体地，随机接入请求消息可以包括随机接入前导码(random access preamble，RA preamble)。其中，RA preamble的主要作用可以是向网络设备请求接入，使网络设备能基于RA preamble估计与终端设备之间的传输时延并以此校准上行定时，并通过RAR消息指示给终端设备。
步骤二、RAR消息的传输，网络设备接收到随机接入请求消息，向终端设备发送RAR消息。其中，RAR消息又可以称之为消息2(Msg2)。
步骤三、消息3的传输，终端设备接收到RAR消息，向网络设备发送Msg3。
步骤四、消息4的传输，网络设备接收到Msg3，向终端设备发送消息4。其中，消息4又可以称之为Msg4。
网络设备在冲突解决机制中，在Msg4中携带该用于唯一标识终端设备的标志以指示胜出的终端设备，而其它没有在冲突解决中胜出的终端设备将重新发起随机接入。
与四步随机接入过程相比，两步随机接入过程有助于降低终端设备的接入时延。其中，两步随机接入过程可以包括如下两个步骤：
步骤1、消息A(即MsgA)的传输，
需要说明的是，终端设备向网络设备发送MsgA。其中，MsgA可以包括随机接入请求消息，这里的随机接入请求消息可以是上述4步随机接入过程中的Msg1。
另外，MsgA可以包括Random Access Preamble和PUSCH payload两部分。
步骤2：消息B(即MsgB)的传输。
需要说明的是，网络设备接收MsgA，并向终端设备发送MsgB。其中，MsgB可以包括RAR。
随机接入信道机会(Random Access Channel Occasion或者Physical Random Access Channel Occasion，RO)：在无线通信系统的下行通信中，系统通过同步信号块(Synchronization Signal and PBCH block，SSB)将同步信号和广播信道周期性地发送给终端设备。同时，基站会配置一个物理随机接入信道(Physical random access channel，PRACH)配置周期(configuration period)。在此PRACH配置周期内配置一定数量的RACH传输机会，即RO。
SSB与RO的关联关系可以通过高层参数ssb-per-rach-occasion(N)或者ssb-perRACH-OccasionAndCB-PreamblesPerSSB或者msgA-SSB-PerRACH-OccasionAndCB-PreamblesPerSSB指示，N的取值可以是{1/8,1/4,1/2,1,2,4,8,16}。如果N<1，代表1个SSB可以映射到多个RO中；如果N＝1，代表1个SSB映射到1个RO中；如果N>1，代表1个RO内可以映射多个SSB。对于频域可以配置的RO数目，也就是在一个时域资源上，频域上RO的数目可以取值为{1，2，4，8}，由高层参数msg1-FDM配置。SSB跟RO的映射周期是指至少完整的映射1轮SSB索引(index)所需要的RO周期，从帧0开始，1个映射周期可以是1个PRACH周期，或者是多个PRACH周期，取决于RO时域资源和频域资源的配置情况。
对于第一类随机接入，或者第二类随机接入(且其RO的配置和第一类随机接入的RO配置是分离的)，每个RO上可用的(或者关联的)前导码中，如果1个RO上映射了N个SSB(N>1)，那么可用的前导码的个数可以分成N份，每一个SSB可取的第一个竞争的前导码的index就是(n指的是SSB index)。其中可通过高层参数totalNumberOfRA-Preambles或者msgA-TotalNumberOfRA-Preambles指示。
如果第二类随机接入和第一类随机接入，采用共同的(common)RO配置，如果1个SSB可以映射到多个RO中(N<1)，每个RO上可用的(或者关联的)前导码中，每个SSB可用的(或者关联的)前导码中，可以用于第二类的随机接入的P个前导码从索引Q开始；
如果1个RO上映射了N个SSB(N>＝1)，每个RO上可用的(或者关联的)前导码中，每个SSB可用的(或者关联的)前导码中，可以用于第二类的随机接入的P个前导码从索引开始。其中可通过高层参数totalNumberOfRA-Preambles或者msgA-TotalNumberOfRA-Preambles指示。Q表示用于第一类随机接入的每个RO关联的每个SSB关联的前导码个数，P表示用于第二类随机接入的每个RO关联的每个SSB关联的前导码个数。

需要说明的是，本申请的TRP并不仅限于相干联合传输或者非相干联合传输场景，还可以适用于其他场景，对此不作具体限制。
如图1b所示的终端设备110的结构示意图，该终端设备110包括处理器210、存储器2 20、通信接口230，以及一个或多个程序221，所述一个或多个程序221被存储在所述存储器220中，并且被配置由所述处理器210执行，所述程序221包括用于执行如本申请方法实施例所描述的方法中终端设备侧的设备所执行的操作。
如图1c所示的网络设备120的结构示意图，该网络设备120包括处理器310、存储器320、通信接口330，以及一个或多个程序321，所述一个或多个程序321被存储在所述存储器320中，并且被配置由所述处理器310执行，所述程序321包括用于执行如本申请方法实施例所描述的方法中网络侧的设备所执行的操作。
请参阅图2a，图2a是本申请实施例提供的一种资源配置方法的流程示意图。如图所示，所述资源配置方法包括如下步骤：
步骤201，网络设备向终端设备发送配置信息。
相应地，所述终端设备获取来自所述网络设备的所述配置信息。
其中，所述配置信息用于指示多个传输接收点TRP中至少一个TRP的随机接入资源。
该配置信息可以是为多个TRP中的每个TRP配置的随机接入资源，也可以是仅为多个TRP中的部分TRP配置的随机接入资源，该多个TRP中的其他TRP的随机接入资源则可以通过推理得出。在本申请实施例中，网络设备可以向终端设备配置多个TRP。
需要说明的是，TRP，可以用传输配置指示状态(transmission configuration indication state，TCI state)、信道探测参考信号(Sounding Reference Signal，SRS)资源、SRS资源集或者空域信息(spatial information)等进行表征。也就是说，TCI状态、SRS资源、SRS资源集或者空域信息等也可以看作是TRP的概念。
另外，本申请中的TRP可以与空域信息或空位方向(例如一个或一组波束)关联；或者，TRP可以通过空域信息或空位方向(例如一个或一组波束)表征；或者，TRP可以通过功控参数表征。此外，本申请中的TRP可以是一个功能模块(例如：采用软件功能实现)，也可以通过硬件实现，本申请并不对TRP的实现方式进行具体限制。
在NR系统中，该随机接入资源可以包括公共随机接入配置信息元素(RACH-ConfigCommon information element)和/或RACH-ConfigCommonTwoStepRA和/或RACH-ConfigDedicated和/或RACH-ConfigGeneric和/或RACH-ConfigGenericTwoStepRA。该配置的随机接入资源中包括用于进行随机接入的时域资源、和/或频域资源和/或随机接入前导码，和/或用于配置物理广播同步广播信号块(Synchronization Signal and PBCH block，SSB)与随机接入资源的映射关系。终端设备可以根据SSB与随机接入资源的映射关系，或者也可以根据测量结果中满足条件的SSB确定其对应的随机资源子集。
步骤202，所述终端设备根据所述配置信息进行随机接入。
其中，终端设备在进行随机接入时，会根据配置的随机接入资源向网络发送随机接入请求信息，然后网络在接收到该随机接入请求信息后，向终端设备发送响应信息。至少一个TRP对应的随机接入资源中可以包括为终端设备配置的两步随机接入和/或四步随机接入资源。随机接入过程可分为基于竞争的随机接入过程和基于非竞争的随机接入过程，基于竞争随机接入是指接入资源由终端设备自行随机获取，基于非竞争随机接入是指终端设备的接入资源由基站分配，二者的本质区别在于发起随机接入前终端设备是否收到来自网络分配的专用随机接入资源。
可见，本实例中，网络设备为终端设备配置的随机接入资源中包括为多个TRP中的至少 一个TRP配置的随机接入资源，这样可以使得每个TRP都有对应的随机接入资源，能有效支持每个TRP的TA，提高终端设备的随机接入效率和质量。
在一个可能的实例中，所述多个TRP中每个TRP分别对应一套随机接入资源。
其中，该配置信息中可以包括为每个TRP分别配置一套随机接入资源，即一套随机接入通用配置信息(RACH-ConfigCommon)和/或2步随机接入通用配置信息(RACH-ConfigCommonTwoStepRA)和/或RACH-ConfigDedicated和/或RACH-ConfigGeneric和/或RACH-ConfigGenericTwoStepRA关联于一个TRP，另一套RACH-ConfigCommon和/或RACH-ConfigCommonTwoStepRA)和/或RACH-ConfigDedicated和/或RACH-ConfigGeneric和/或RACH-ConfigGenericTwoStepRA关联另一个TRP。
可见，本实例中，可以在配置信息中为每个TRP分别配置一套随机接入资源，这样可以使得每个TRP都有对应的随机接入资源，能有效支持每个TRP的TA，提高终端设备的随机接入效率和质量。
在一个可能的实例中，所述多个TRP中包括第一TRP和第二TRP，所述配置信息包括：所述第一TRP的第一随机接入资源和/或所述第二TRP的第二随机接入资源。
其中，当仅为第一TRP和第二TRP中的其中一个TRP配置随机接入资源时，另一个TRP的随机接入资源可以通过推理得出。
在一个可能的实例中，所述第一随机接入资源为相应于第一物理小区标识PCI的资源，所述第二随机接入资源为相应于第二PCI的资源，所述第一PCI为服务小区的PCI，所述第二PCI为1个或多个非服务小区中的任意一个非服务小区的PCI。
其中，小区间多传输接收点(inter-cell M-TRP)场景中，可以为每个第二服务小区，即非服务小区，分别配置随机接入资源。服务小区的SSB关联的物理小区标识(Physical Cell Identifier，PCI)和非服务小区的SSB关联的PCI不同，非服务小区的SSB与PCI的关联关系可以是通过SSB-MTC-Additional PCI配置。需要说明的是，PCI可以用于区分不同小区或不同小区的信号，即PCI可以关联小区。因此，本申请可以使得参数关联PCI，以便实现参数关联小区，即实现通过参数来区分不同小区或不同小区的信号。当为两个TRP进行随机接入资源配置，一个TRP的随机接入资源是相应于服务小区的PCI的资源，另一个TRP的随机接入资源可以是相应于非服务小区中的任意一个非服务小区的PCI的资源。
可见，本实例中，两个TRP的随机接入资源分别是相应于服务小区和非服务小区的PCI的资源，可以有效支持每个TRP的TA，提高终端设备的随机接入效率和质量。
在一个可能的实例中，当所述第二PCI为用于物理下行共享信道PDSCH的活跃的传输配置指示TCI状态所关联的非服务小区的PCI，所述第二随机接入资源可用。
其中，所述第二随机接入资源可用是指所述终端设备可以根据为第二TRP配置的随机接入资源进行随机接入。终端设备与网络设备基于波束进行数据传输时，通常为终端设备配置传输服务小区的TCI，即为终端设备进行服务小区的波束配置。
在一个可能的实例中，所述多个TRP对应一套随机接入资源。
其中，该多个TRP对应一套随机接入资源可以是所述多个TRP中的部分TRP对应同一套随机接入资源，其他部分TRP对应另一套随机接入资源。也可以是多个TRP中的每个TRP都对应同一套随机接入资源。
在一个可能的实例中，所述多个TRP对应的一套随机接入资源中包括所述多个TRP中 至少一个TRP在一个随机接入信道机会RO中关联的前导码信息。
其中，当多个TRP都配置的是同一套随机接入资源，对于同一个RO，不同的TRP关联不同的前导码，前导码是终端设备在PRACH中发送的实际内容，由长度为Tcp的循环前缀CP和长度为Tseq的序列Sequence组成。一套随机接入资源包括的前导码信息中包括每个TRP在同一个RO中关联的前导码的数量和/或前导码的索引。
可见，本实例中，多个TRP共享同样的随机接入资源配置时，通过对于同一个RO不同的TRP关联不同的前导码的方式实现每个TRP的随机资源配置，可以有效支持每个TRP的TA，提高终端设备的随机接入效率和质量。
在一个可能的实例中，所述多个TRP对应的一套随机接入资源中包括为所述终端设备配置第一类随机接入，与所述第一类随机接入有关的每个RO关联的每个SSB关联的前导码的数量为X1个，所述X1为整数。
其中，每个SSB可用的(或者关联的)前导码个数可以由高层参数CB-PreamblesPerSSB或者ssb-perRACH-OccasionAndCB-PreamblesPerSSB或者msgA-SSB-PerRACH-OccasionAndCB-PreamblesPerSSB或msgA-CB-PreamblesPerSSB-PerSharedRO指示，根据RO和SSB的映射关系还可以知道每个RO映射的SSB的数量。该X1可以是第一TPR和第二TRP对应的一套随机接入资源中包括的前导码信息指示的，即与第一类随机接入有关的一个RO可用的前导码中，有X1个前导码为该一个RO映射的一个SSB可用的前导码。所述第一类随机接入对应的随机接入类型可以是上述所说的四步随机接入。对于第一类映射关系(即上述所述的SSB与RO的映射关系中N<1的情况)来说，由于是一个SSB对应多个RO，因此所述数量X1可以理解为是一个RO关联的用于竞争接入的前导码的数量，或者一个RO所关联的用于非竞争接入的前导码的数量。对于第二类映射关系(即上述所述的SSB与RO的映射关系中N＝1或N>1的情况)来说，由于是一个RO关联多个SSB，因此若每个SSB关联的前导码数量都为X1，当一个RO关联N个SSB时，一个RO关联的用于竞争接入的前导码的数量，或者一个RO所关联的用于非竞争接入的前导码的数量为N*X1。
在一个可能的实例中，所述至少一个TRP包括第一TRP和第二TRP，所述每个SSB关联的X1个前导码中，前X1-L1个前导码与所述第一TRP关联，后L1个前导码与所述第二TRP关联，所述L1为整数。
其中，本方案中描述的每个SSB指的是每个RO关联的每个SSB。该X1和/或L1和/或X1-L1可以是第一TPR和第二TRP对应的一套随机接入资源中包括前导码信息指示的，即与第一类随机接入有关的一个RO可用的前导码中，有X1个前导码为该一个RO映射的一个SSB可用的前导码，而该X1个前导码中，有L1个前导码与第一TRP有关，有X1-L1个前导码与第二TRP有关。如图2b所示，图2b中的(a)中所示的为SSB与RO的映射关系为第一类映射关系时，一个SSB关联的每个TRP关联的前导码的数量。即此时X1个前导码中，前X1-L1个前导码与第一TRP关联，后L1个前导码与第二TRP关联。图2b中的(b)所示的为SSB与RO的映射关系为第二类映射关系时，一个SSB关联的每个TRP关联的前导码的数量。一个SSB关联的X1个前导码仅为该RO关联的所有前导码中的的一部分，在这一部分中，前X1-L1个前导码与第一TRP关联，后L1个前导码与第二TRP关联。特别地，第n个SSB关联的X1个前导码从索引为(n-1)*X1的前导码开始。例如第1个SSB的X1个前导码就从索引为0的前导码开始，例如第2个SSB的X1个前导码就从索引为X1的前导 码开始。
在一个可能的实例中，所述至少一个TRP包括第一TRP和第二TRP，所述每个SSB关联的X1个前导码中，所述第一TRP关联的前导码的数量为K个，所述第二TRP关联的前导码的数量根据对所述第一TRP关联的前导码的数量推理得到，所述K为整数。该K可以是第一TPR和第二TRP对应的一套随机接入资源中包括的前导码信息指示的，即与第一类随机接入有关的一个RO可用的前导码中，有X1个前导码为该一个RO映射的一个SSB可用的前导码，而该X1个前导码中，有K个前导码与第一TRP有关。
在一个可能的实例中，所述至少一个TRP包括第一TRP和第二TRP，所述每个SSB关联的X1个前导码中，所述第一TRP关联X个前导码，所述第二TRP关联Y个前导码，所述X和/或所述Y为网络配置信息或协议预定义信息，所述X和Y为整数。可以通过协议预定的方式，直接或者间接获得第一TRP和/或第二TRP对应的前导码数量。
在一个可能的实例中，所述至少一个TRP包括第一TRP和第二TRP，所述每个SSB关联的X1个前导码中，所述第一TRP的比例因子为α，所述第二TRP的比例因子为(1-α)，所述比例因子用于指示所述第一TRP关联的前导码数量和/或所述第二TRP关联的前导码数量。也就是说，此时第一TRP关联的前导码的数量为X1*α，第二TRP关联的前导码的数量为X1*(1-α)。网络可以为第一TRP和/或第二TRP配置比例因子，若网络仅为第一TRP配置比例因子，则此时第二TRP关联的前导码的数量为通过推导得出。特别地，当X1*α的值不为整数时，需要对该值进行取整计算，该取整方式可以是向上取整或向下取整或者取该值中的整数部分等方式。当然，网络可以为第一TRP和/或第二TRP配置比例因子。
可见，本实例中，通过对于同一个RO，不同的TRP关联不同的前导码的方式实现每个TRP的随机资源配置，可以有效支持每个TRP的TA，提高终端设备的随机接入效率和质量。
在一个可能的实例中，所述多个TRP对应的一套随机接入资源中还包括为所述终端设备配置第二类随机接入，所述第一类随机接入与所述第二类随机接入分别对应一套物理随机接入信道PRACH配置，所述至少一个TRP在一个RO中关联的前导码信息与所述第一类随机接入关联和/或与所述第二类随机接入关联。
其中，所述第二类随机接入对应的随机接入类型可以是上述所说的两步随机接入。当同时配置了第一类随机接入和第二类随机接入，但第一类随机接入进程和第二类随机接入进程采用分开的物理随机接入信道(Physical Random Access Channel，PRACH)配置，则与所述第二类随机接入有关的每个RO关联的每个SSB关联的前导码的数量为X2个，所述X2为整数。所述至少一个TRP包括第一TRP和第二TRP，所述每个SSB关联的X2个前导码中，前X2-L4个前导码与所述第一TRP关联，后L4个前导码与所述第二TRP关联，所述L4为整数。该X2和/或L4和/或X2-L4可以是第一TPR和第二TRP对应的一套随机接入资源中包括的前导码信息指示的，即与第二类随机接入有关的一个RO可用的前导码中，有X2个前导码为该一个RO映射的一个SSB可用的前导码，而该X2个前导码中，有L4个前导码与第一TRP有关，有X2-L4个前导码与第二TRP有关。可以理解的是，第一类随机接入关联的RO和第二类随机接入关联的RO中每个SSB关联的前导码的配置方式相同，每个SSB关联的TRP的前导码的配置方式也相同。需要说明的是，虽然配置方式相同，但配置的前导码的数量可以不同。
可见，本实例中，通过对于同一个RO，不同的TRP关联不同的前导码的方式实现每个 TRP的随机资源配置，可以有效支持每个TRP的TA，提高终端设备的随机接入效率和质量。
