Description

用于随机接入的方法和装置 技术领域
本申请涉及通信领域，并且更具体地，涉及通信领域中的用于随机接入的方法和装置。
背景技术
在无线通信技术中，终端设备通过随机接入过程获得和网络设备的上行同步。在发起随机接入过程中，终端设备需要先根据网络设备广播的随机资源配置信息确定随机接入资源，其中，随机资源配置信息用于指示参考信号与随机接入资源的对应关系；具体地，终端设备检测到某一参考信号，则根据该随机资源配置信息确定随机接入资源，并在确定的随机接入资源上向网络设备发送随机接入前导码(preamble)。其中，网络设备可以通过一个波束发送一个参考信号，每个波束发送的每个参考信号与相应的随机接入资源对应。
目前在新无线(new radio，NR)中，协议规定网络设备最多通过64个发送波束发送64个参考信号，随着网络吞吐量的增加，需要更高的频段，如果采用64个发送波束覆盖所有的频段则存在困难。为了覆盖所有的频段需要增加同步信号/物理广播信道SS/PBCH(以下简称SSB)的数量，这样导致SSB的开销增加，为了避免SSB的开销增加，可以采用一个波束的多个波峰发送一个SSB，这种多峰波束可以覆盖多个方向，从而可以降低SSB的开销。在这种情况下，一个波束的多个波峰发送一个SSB，终端设备接收到SSB时，无法确定是在一个波束的哪个波峰上接收到的SSB，相应地，终端设备也无法确定发送随机接入前导码的资源，从而导致无法发起随机接入，因此，亟需一种确定随机接入资源的方法。

具体实施方式
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th generation,5G)系统或新无线(new radio，NR)等。
本申请实施例中的终端设备可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol， SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network,PLMN)中的终端设备等，本申请实施例对此并不限定。
本申请实施例中的网络设备可以是任意一种具有无线收发功能的设备。该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，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，还可以为第五代(the fifth generation,5G)系统，例如，新空口(new radio,NR)中的gNB或传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，例如基带单元(BBU)或分布式单元(distributed unit,DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit,CU)和分布式单元(distributed unit,DU)。gNB还可以包括有源天线单元(active antenna unit,AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
参见图1，图1是适用于本申请实施例的通信系统的架构图。如图1所示，该无线通信系统中可以包括至少一个网络设备101，网络设备101和一个或多个终端设备(例如图1中所示的终端设备102和终端设备103)进行通信。当网络设备发送信号时，网络设备为发射端，终端设备为接收端。反之，当终端设备发送信号时，终端设备为发射端，网络设备为接收端。
在无线通信系统中，终端设备在与网络设备进行通信之前，先要发起随机接入过程来获得与网络设备的上行同步，图2是随机接入过程示意图200，包括：
S210，网络设备向终端设备发送广播消息，该广播消息中携带资源配置信息，资源配置信息用于指示同步信号/物理广播信道块(synchronization signal/physical broadcast channel，SS/PBCH)与随机接入资源的对应关系。
其中，随机接入资源可以包括时域、频域和码域资源中的一种或多种。
S220，网络设备通过空间扫描方式发送SSB，终端设备检测SSB。
具体地，S220中，网络设备通过一个发送波束发送一个SSB，一个发送波束对应唯一的SSB，即S220中资源配置信息也可以理解为用于指示发送波束与随机接入资源的对应关系，网络设备的一个发送波束对应一个(组)随机接入资源。
S230，终端设备根据检测到的SSB与S210中的资源配置信息，确定随机接入资源。
S240，终端设备在S230确定的随机接入资源上向网络设备发送随机接入前导码(preamble)，也称为消息1，网络设备在随机接入资源上接收终端设备发送的随机接入前导码。
S250，网络设备根据S240的随机接入资源以及S210的资源配置信息确定发送随机接入响应(random access response，RAR)的发送波束。
具体地，S250，包括：网络设备在哪个随机接入资源上接收到随机接入前导码则根据资源配置信息可以确定终端设备是在哪个波束上接收到的SSB，利用该波束发送RAR。
S260，网络设备利用时S250确定的发送波束向终端设备发送RAR，也称为消息2。RAR携带上行授权信息、临时小区无线网络临时标识(temporary cell radio network temporary identifier，T-CRNTI)、时间提前量(timing advance，TA)中的至少一种。
其中，上行授权信息用于指示发送初始上行信息的资源，TA用于终端设备获知上行定时。
S270，终端设备在上行授权信息指示的资源上向基站发送初始上行信息，也称为消息3，初始上行信息携带终端设备竞争解决的标识(UE Contention Resolution Identity)。
S280，基站接收到终端设备的初始上行信息之后，基站进行竞争解决，基站向终端设备发送竞争解决信息，也称为消息4。
在NR中，协议规定在S220中，网络设备最多通过64个发送波束发送64个参考信号，随着网络吞吐量的增加，需要更高的频段，如果采用64个发送波束覆盖所有的频段则存在困难。为了覆盖所有的频段需要增加SSB的数量，这样导致SSB的开销增加，并且发送更多数量的SSB需要占用更多的资源。为了降低SSB的数量，如图3所示，可以采用一个波束的多个波峰发送一个SSB，这种多峰波束可以覆盖多个方向，从而可以降低SSB的开销。在这种情况下，一个波束的多个波峰发送一个SSB，终端设备接收到SSB时，无法确定是在一个波束的哪个波峰上接收到的，相应地，在上述随机接入过程中，在S230中终端设备无法确定发送随机接入前导码的资源，从而导致无法发起随机接入，并且网络设备通过多个波峰发送了SSB但无法确定终端设备是在哪个波峰上接收到了SSB，即使网络设备接收到随机接入前导码，网络设备在S250中也无法确定采用哪个波峰向终端设备发送随机接入响应，因此，会导致随机接入失败。
可以理解的是，本申请实施例中的波峰可以是波束(beam)的一个分量或者子分量，波峰也可以称为窄峰、子波束(sub-beam)、窄波束或者波束分量(beam component)。如图4所示，波峰可以是某一个波束的一个子方向或者某一个波束的L度，如L等5。
下面结合附图描述本申请实施例提供的用于随机接入的方法500，方法500包括：
S510，网络设备向终端设备发送参考信号的分组信息，所述分组信息用于指示参考信号的分组情况。
相应地，终端设备接收网络设备发送的参考信息的分组信息。
可选地，方法500可以不包括S510，网络设备不需要配置参考信号的分组信息，终端设备可以根据协议规定获取参考信号的分组信息，或者参考信号可以不进行分组，所有的参考信号为一组。
可选地，所述分组信息用于指示每组参考信号的数量，例如，默认存在一组参考信号，不需要指示组的数量。
可选地，所述分组信息用于指示参考信号的组的总数量，例如，默认每组参考信号存在一个参考信号，不要指示每组参考信号的数量。
可选地，分组信息用于指示M个参考信号为一组，共N组参考信号，M和N为正整数。
例如，分组信息用于指示4个参考信号为一组，共16组参考信号；又例如，分组信息用于指示64个参加信号为一组，共一组参考信号。
需要说明的是，本申请实施例提到的参考信号可以为SSB，SSB包括主同步信号(primary synchronization signal，PSS)、辅同步信号(secondary synchronization signal，SSS)、物理广播信道(physical broadcast channel，PBCH)，以及为了解调PBCH所需的解调参考信号(demodulation reference signal，DMRS)。PSS和SSS用于终端设备进行下行同步，包括定时同步、帧同步和符号同步；PSS和SSS还用于获取小区标识(ID)以及测量小区信号质量。
S520，网络设备向终端设备发送参考信号。
具体地，S520，包括：网络设备通过广播的方式发送参考信号。
若分组信息用于指示M个参考信号为一组，共N组参考信号，则S520包括，网络设备向终端设备发送M*N个参考信号。可选地，网络设备可以通过M*N个波束发送M*N个参考信号，一个波束对应一个参考信号，并且，网络设备发送M*N个波束每个波束具有多个波峰，这样可以利用一个波束的多个波峰发送SSB，其中，*表示相乘运算。
需要说明的是，S510和S520的顺序不限。
S530，相应地，终端设备检测网络设备发送的参考信号，若终端设备检测到至少一个参考信号，终端设备根据分组信息确定发送随机接入前导码的第一随机接入资源。
在一种可能的实现方式中，S530，包括：所述终端设备根据所述分组信息确定第一检测序列；所述终端设备根据所述第一检测序列确定所述第一随机接入资源。
可选地，若分组信息用于指示M个参考信号为一组，共N组参考信号，第一检测序列的长度与M相关。
下面结合实施例描述如何确定第一检测序列。
具体地：若终端设备检测到至少一个参考信号，终端设备可以根据分组信息和至少一个参考信号的索引得到第一检测序列。具体地，终端设备可以根据分组信息确定总的参考信号数量，可以预设参考信号的索引，例如，若终端设备确定参考信号的数量为M*N，则M*N个参考信号的索引分别为0，1，……，M*N-1。
举例来说，若分组信息指示4个参考信号为一组，共16组参考信号，假设默认64参考信号的索引分别为0，……，63，则若终端设备只接收到一个参考信号的索引为62，则可以确定第一检测序列的为0010；若终端设备接收到两个参考信号的索引分别为56和57，则可以确定第一检测序列的为1100，即此时第一检测序列为量化得到的序列。
可选地，如果用一个bit指示是否检测到一个参考信号，则第一检测序列的长度为M；如果为p个比特指示是否检测到一个参考信号，则第一检测序列的长度为pM，例如p＝2，结合上述例子，若终端设备接收到一个参考信号的索引为62，则可以确定第一检测序列的长度为00001100。
可以理解的是，若终端设备接收到两个或两个以上的参考信号，并且这两个或两个以上的参考信号的索引不是连续的几个索引，则终端设备可以选择参考信号的接收功率(reference signal receiving power，RSRP)较大或者最大的确定第一检测序列，或者终端设备可以任意选择一个确定第一检测序列。结合上述的例子，若终端设备接收到参考信号的索引分别为56、57和62，根据分组信息可知，索引为56和57的参考信号为一个组，但是与索引为62的参考信号不是一个组，这样索引为56和57的参考信号对应的序列为1100，索引为62的参考信号对应的序列为0010，终端设备可以在这两个序列中任意选择一个作为第一检测序列，或者终端设备确定索引为56、57和62的这三个参考信号中RSRP最高的参考信号的索引，例如索引为62的参考信号的RSRP最高，则终端设备可以确定第一检测序列为0010。
可选地，终端设备可以根据RSRP阈值确定是否检测到参考信号，若某一个参考信号的RSRP大于RSRP阈值，则可以确定检测到参考信号，如果某一个参考信号的RSRP小于RSRP阈值，则可以确定没有检测到参考信号。其中，RSRP阈值可以是预设的也可以是网络设备发送给终端设备的。
下面结合两种方式描述如何根据第一检测序列确定第一随机接入资源。
方式一，终端设备根据第一检测序列与第一对应关系确定发送所述随机接入前导码的第一随机接入资源，第一对应关系用于指示至少一个检测序列与至少一个随机接入资源对应，至少一个检测序列包括所述第一检测序列，至少一个随机接入资源包括第一随机接入资源。例如，第一对应关系用于指示至少一个检测序列中每个检测序列与至少一个随机接入资源中每个随机接入资源一一对应。
可选地，终端设备保存有第一对应关系，第一对应关系可以是网络设备发送给终端设备的(例如通过S210中的广播消息发送)或者是协议规定的。第一对应关系如表1所示，表1中n为正整数，例如，n为16。

检测序列1 随机接入资源1
检测序列2 随机接入资源2
检测序列3 随机接入资源3
检测序列4 随机接入资源4
…… ……
检测序列n 随机接入资源n
方式二，终端设备根据第一检测序列与第二对应关系确定网络设备发送所述至少一个参考信号的第一波峰，第二对应关系用于指示至少一个检测序列与至少一个波峰对应，至少一个检测序列包括第一检测序列，至少一个波峰包括第一波峰，例如，第二对应关系用 于指示至少一个检测序列中每个检测序列与至少一个波峰中每个波峰一一对应；终端设备根据第一波峰与第三对应关系确定发送所述第一随机接入前导码的第一随机接入资源，第三对应关系用于指示至少一个波峰与至少一个随机接入资源对应，至少一个随机接入资源包括第一随机接入资源，例如，第三对应关系用于指示至少一个波峰中每个波峰与至少一个随机接入资源中每个随机接入资源一一对应。
可选地，终端设备保存有第二对应关系和第三对应关系。第二对应关系和第三对应关系可以是网络设备发送给终端设备的(例如通过S210中的广播消息发送)，也可以是协议规定的。可选地，第二对应关系和第三对应中的一个是网络设备发送给终端设备的，另外一个可以是协议规定的。第二对应关系如表2所示，第三对应关系如表3所示，表2和表3中m是正整数，例如m为15。

波峰m 随机接入资源m
可选地，前述提到的检测序列与随机接入资源的第一对应关系，或者波峰与随机接入资源的第三对应关系中提到的随机接入资源可以是网络设备配置的随机接入资源也可以是根据波束与随机接入资源之间的对应关系确定的。具体来说，在S210中可以的资源配置信息可以配置第一对应关系或者第三对应关系，或者，在S210中的资源配置信息可以指示波束与随机接入资源的关系并且配置每个波束(每个参考信号)的波峰数目，这样，终端设备可以根据波束与随机接入资源的关系以及每个波束的波峰数目确定每个波峰对应的随机接入资源。举例来说，资源配置信息指示一个随机接入机会(RACH occasion，RO)上总共有64个随机接入前导(随机接入资源可以包括随机接入前导)，共有8个波束，每个波束有4个波峰(这里是举例，每个波束的波峰数据可以不同)，这样，每个波 峰对应2((64/8)/4)个随机接入前导，可以将一个波束的连续的2个随机接入前导分配给一个波峰。
在另一个可能的实现方式中，S530包括：所述终端设备根据所述分组信息确定第一波峰。所述终端设备根据所述第一波峰和第四对应关系确定发送所述随机接入前导码的所述第一随机接入资源。所述第四对应关系用于指示至少一个波峰与至少一个随机接入资源对应，所述至少一个波峰包括所述第一波峰，所述至少一个随机接入资源包括所述第一随机接入资源，例如，第四对应关系可以如表3所示。
下面结合实施例描述如何确定第一波峰。
具体地，终端设备可以根据参考信号的分组信息，利用接收到的一组参考信号的值(未量化的值)以及预设算法确定第一波峰。
下面举例描述：
若参考信号的分组信息用于指示4个参考信号为一组，共16组参考信号，则终端设备可以根据接收到的一组参考信号的值来解算得到第一波峰，终端设备接收到的4次参考信号的值可以表示为：y i＝aDb i+z i。
其中，i＝1,…,4，y i为接收到的一次参考信号的值，若某一次没有接收到参考信号，则该参考信号的值为0，a为1×N的复向量，N为参考信号总的波峰数量，a的第n(n＝1,…,N)列的元素表示第n个波峰方向的信道复增益。D是N×N的波峰基底，D的某一列表示一个窄峰的指向向量，比如某一列可以为离散傅里叶变换(discrete fourier transformation，DFT)向量，b i为一个参考信号的多峰信息，b i为N×1的向量，一个参考信号的多峰信息用于指示该参考信号可以通过哪些波峰发送，例如一个参考信号的多峰信息为(100010011010111) T，其中，0表示在该波峰上没有发送参考信号，1表示在该波峰上发送参考信号，这样，可以通过15个波峰中的8个波峰发送该参考信号。z i为噪声。
在上述的公式中D可以是预设的或者是网络设备配置的，b i也可以是预设的或者网络设备配置的，终端设备接收到一次参考信号就可以确定y i，则终端设备当接收到一组参考信号时，可以根据上述公式确定a，a的N列中，值最大的一列对应的波峰即为第一波峰。需要说明的是，可以配置参考信号的分组信息所指示的M个参考信号为一组中的M，足够使得通过上述算法确定a。可以设置a中的非稀疏的元素的数量可以与M相等，a的非稀疏的元素可以为大于预设值(如预设值为0)。举例来说，上述的N＝15，即a是1×15的复向量，则为了确定a的15个元素，至少需要15个等式(至少需要接收15次参考信号)，但是由于a可能是稀疏矩阵，则可以接收少于15次参考信号，例如4次，即此时M＝4。
本申请实施例中，上述只是举例说明如何解算得到第一波峰，还可以通过其他的方式得到第一波峰，本申请不予限制。在本申请实施例中用于解算得到第一波峰的参数可以是预设的或者是网络设备配置的，本申请不予限制。
S540，终端设备在第一随机接入资源上向网络设备发送所述随机接入前导码。
相应地，网络设备在第一随机接入资源上接收终端设备发送的随机接入前导码。
作为一个可选实施例，方法500还包括：网络设备根据第一随机接入资源确定向终端设备发送随机接入响应的第一波峰，这样，网络设备可以通过第一波峰向终端设备发送随机接入响应。
若分组信息用于确定所述终端设备第一检测序列，第一检测序列用于终端设备确定第 一随机接入资源，网络设备根据第一随机接入资源确定向终端设备发送随机接入响应的第一波峰可以通过以下两种方式中的一种方式实现：
方式一，所述网络设备根据前述的第一对应关系和所述第一随机接入资源确定第一检测序列；网络设备根据第二对应关系和所述第一检测序列确定向所述终端设备发送所述随机接入响应的所述第一波峰；
这样，网络设备可以根据随机接入资源和检测序列的第一对应关系确定终端设备得到的第一检测序列，网络设备再根据检测序列与波峰的对应关系确定的第一波峰，在该第一波峰上终端设备接收到了网络设备发送的参考信号，这样，网络设备可以在该第一波峰上发送随机接入响应，这样，终端设备也能接收网络设备在该第一波峰上发送的随机接入响应，从而可以提高随机接入的成功率。
可选地，第一对应关系和第二对应关系可以是网络设备确定的发送给终端设备(例如通过S210中的广播消息发送)，或者可以是协议规定的，或者第一对应关系和第二对应关系中的一个是网络设备确定的并发送给终端设备，另外一个是协议规定的，本申请实施例不予限制。
方式二，所述网络设备根据所述第三对应关系和所述第一随机接入资源确定向所述终端设备发送所述随机接入响应的所述第一波峰。
这样，网络设备可以根据随机接入资源与波峰的第三对应关系确定终端设备在第一波峰上接收到的参考信号，也可以保证终端设备能够接收到网络设备通过第一波峰上发送随机接入响应，从而可以提高随机接入的成功率。
可选地，第三对应关系可以是网络设备确定的发送给终端设备，或者可以是协议规定的，本申请实施例不予限制。
若分组信息用于确定所述终端设备第一波峰，第一波峰用于终端设备确定第一随机接入资源，则网络设备可以根据前述的第四对应关系以及第一随机接入资源确定第一波峰。
这样，网络设备可以根据随机接入资源与波峰的第四对应关系确定终端设备在第一波峰上接收到的参考信号，也可以保证终端设备能够接收到网络设备通过第一波峰上发送随机接入响应，从而可以提高随机接入的成功率。
可选地，第四对应关系可以是网络设备确定的发送给终端设备，或者可以是协议规定的，本申请实施例不予限制。
下面结合图6描述本申请实施例提到的用于随机接入的方法600，方法600以参考信号为SSB为例描述，不应该造成对本申请实施例的任何限制，方法600包括：
S610，网络设备发送第一对应关系，例如网络设备可以向一个或多个终端设备发送第一对应关系。
相应地，终端设备接收网络设备发送的第一对应关系。
具体地，网络设备可以通过广播/组播等方式向终端设备发送第一对应关系。
S620，网络设备发送SSB的分组信息，该分组信息用于指示M个参考信号为一组，共N组参考信号。
相应地，终端设备接收网络设备发送的SSB的分组信息。
需要说明的是，S610和S620的顺序不作限定，S610和S620可以同时执行也可以分分别执行。并且，网络设备可以在同一个广播消息中向终端设备发送第一对应关系和SSB 的分组信息，也可以在不同的广播消息中向终端设备发送第一对应关系和SSB的分组信息，本申请实施例不予限制。
S630，网络设备发送多个SSB，例如，网络设备向一个或多个终端设备发送多个SSB。
相应地，终端设备检测SSB。
可选地，网络设备可以广播或者组播多个SSB。
S640，若终端设备检测到至少一个SSB，则可以根据S620中的SSB的分组信息确定第一检测序列。
具体地，S640中，终端设备确定第一检测序列的方式参考方法500的描述。
S650，终端设备根据第一检测序列以及S610中的第一对应关系确定第一随机接入资源。
可选地，第一对应关系如表1所示。终端设备可以根据表1确定第一随机随机接入资源。
S660，终端设备在第一随机接入资源上向网络设备发送随机接入前导码(preamble)。
相应地，网络设备在第一随机接入资源上接收到终端设备发送的随机接入前导码。
S670，网络设备根据第一对应关系确定第一检测序列。
S680，网络设备根据第一检测序列以及第二对应关系确定第一波峰。
举例来说，网络设备按照如下矩阵发送四个SSB，该矩阵的每一行表示一个SSB，从上到下四行分别对应SSB1，SSB2，SSB3，SSB4，每一个列表示一个波峰，总共有15列对应15个波峰，第一行存在8个1表示网络设备在这8个波峰上发送SSB1，第二行也存在8个1，表示网络设备在这8个波峰上发送了SSB2，依次类推，矩阵中为0的元素表示在该波峰上没有发送SSB。相应的第二对应关系如表4所示，表4中的检测序列为该矩阵中的某一个列，以表4的第3行为例，若终端设备确定的检测序列为0100，则终端设备可以确定在第二个波峰接收到了网络设备发送的SSB2，则该第一波峰为第二个波峰。相应地，网络设备通过第二个波峰向终端设备发送随机接入响应。
