Description

一种随机接入配置方法及装置
本申请要求在2017年3月24日提交中国专利局、申请号为201710184927.9、申请名称为“一种随机接入配置方法及装置”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
本发明实施例涉及通信技术领域，尤其涉及一种随机接入配置方法及装置。
背景技术
移动业务的发展对无线通信的数据速率和效率要求越来越高。在未来的无线通信***中，波束成型技术用来将传输信号的能量限制在某个波束方向内，从而增加信号和接收的效率。
在基站与终端设备(User Equipment，UE)进行通信之前，UE首先需要接入基站，目前UE一般是通过随机接入来实现接入。请参见图1A，为长期演进(Long Term Evolution，LTE)***中的随机接入(Random access，RA)过程的示意图。在LTE***中，进行随机接入时，UE首先进行下行同步，从物理层广播信道(Physical broadcast channel，PBCH)中获取***帧号等主要***信息，然后再接收其它下行***信息。其中，UE从接收的第二类***信息块(System information block-2，SIB2)中获取随机接入资源信息。
图1B为SIB2的广播周期示意，SIB2的广播周期为T，T可以由基站配置。其中，基站发送的***信息与随机接入资源信息之间的关系如图1C所示。在随机接入资源信息中，指示了UE可以发送随机接入的时间密度、频率、以及序列等资源，如图1D中的资源1、资源2、以及资源3所示。其中，时间密度包括随机接入在每个***帧(System frame number，SFN)中的数量以及位置。然后UE根据随机接入资源信息，生成随机接入前导(preamble)，在随机接入资源信息所指示的时间及频率位置发送该随机接入前导。
在LTE***中，基站使用相同的波束与本基站覆盖范围的内的UE进行信息传输。而在未来的第五代移动通信技术(5G)***中，基站可能会使用多个波束与本基站覆盖范围的内的UE进行信息传输。因此，LTE***的这种单波束的方法不适用于类似于5G***的这种多波束网络。

本发明实施例中，网络设备会生成多个下行信号，每个下行信号都关联随机接入配置信息，不同的下行信号可以承载在不同的下行发送波束中发送，这就实现了多波束的处理，使得本发明实施例提供的技术方案能够适用于类似于5G***的这种多波束网络。
而且本发明实施例中，不同的下行信号关联的随机接入配置信息可能是不同的，那么 对于覆盖较多终端设备的下行信号，为其关联的随机接入配置信息就可以用于指示比较多的随机接入资源，而对于覆盖较少终端设备的下行信号，为其关联的随机接入配置信息就可以用于指示比较少的随机接入资源，从而使得随机接入资源能够得到较为合理的配置，避免资源浪费，提高了资源的利用率。
在一个可能的设计中，随机接入配置信息包括用于指示终端设备进行随机接入的时间配置信息。其中，时间配置信息包括终端设备进行随机接入的结束时间和持续时间中的至少一种，以及终端设备进行随机接入的起始时间。
随机接入配置信息可以指示终端设备进行随机接入的时间配置信息，从而终端设备根据该时间配置信息就能在准确的位置进行随机接入。
在一个可能的设计中，用于指示终端设备进行随机接入的时间配置信息包括：OFDM符号、mini-slot、子帧、以及帧中的至少一种。
给出了时间配置信息的几种形式，在本发明实施例中时间配置信息的形式不限于以上列举的几种。
在一个可能的设计中，下行信号为SS block、SS burst、SS burst set、***信息中的至少一种。
本发明实施例中，下行信号可能有不同的形式，且以上几种只是举例，本发明实施例不限制下行信号的形式。
第二方面，提供一种随机接入配置方法，该方法可以由网络设备执行，网络设备例如为基站。该方法包括：网络设备确定多个下行信号组，不同的下行信号组关联不同的随机接入配置信息。网络设备将多个下行信号组以及多个下行信号组关联的随机接入配置信息发送给终端设备。
在本发明实施例中，基站除了可以为不同的下行信号关联不同的随机接入配置信息之外，还可以将下行信号进行分组，这样，除了可以减少资源浪费之外，还可以使得下行信号更为规范。
在一个可能的设计中，一个下行信号组中包括多个下行信号，同一个下行信号组中的各个下行信号所关联的随机接入配置信息相同。
网络设备为同一个下行信号组包括的各个下行信号关联相同的随机接入配置信息，不同的下行信号组关联不同的随机接入配置信息，实现了对于下行信号的分区管理。
在一个可能的设计中，下行信号组关联的随机接入配置信息包括随机接入配置信息所指示的下行信号分组的随机接入的起始时间、随机接入的持续时间、随机接入的结束时间、随机接入所使用的频域资源、下行信号数量、以及随机接入所使用的序列资源中的至少一种。
随机接入配置信息可用于指示相应的随机接入资源的时域、频域、以及序列等资源，从而终端设备根据接收的随机接入配置信息就能在正确的位置进行随机接入。
在一个可能的设计中，下行信号组关联的随机接入配置信息包括随机接入配置信息所指示的下行信号的时间配置索引。时间配置索引用于终端设备根据时间配置索引确定随机接入资源的开始时间、占用的频域资源、下行信号数量、以及随机接入所使用的序列资源中的至少一种。
终端设备接收下行信号中的随机接入配置信息后，根据时间配置信息中的时间配置索引进行查表，通过查表结果或通过根据查表结果进行计算的方式确定随机接入资源的开始 时间、占用的频域资源、下行信号数量、以及随机接入所使用的序列资源中的至少一种。或者，终端设备除了使用时间配置索引之外，还可以进一步结合下行信号索引和/或下行信号组的索引，通过查表或者根据查表结果计算的方式，得到该下行信号关联的随机接入资源的具***置，也就是确定随机接入资源的开始时间、占用的频域资源、下行信号数量、以及随机接入所使用的序列资源中的至少一种。那么，时间配置信息只需包括时间配置索引就可以使得终端设备确定随机接入资源，有效降低了信令的开销。

或者，下行信号是SS burst set，那么基站将多个下行信号分组指的是将多个SS burst set进行分组，一个下行信号组包括至少一个SS burst set。
或者，下行信号是***信息，那么基站将多个下行信号分组指的是将多个***信息进行分组，一个下行信号组包括至少一个***信息。

在一个可能的设计中，下行信号组关联的随机接入配置信息包括随机接入配置信息所指示的下行信号的时间配置索引。时间配置索引用于终端设备根据时间配置索引确定随机接入资源的开始时间、占用的频域资源、下行信号数量、以及随机接入所使用的序列资源中的至少一种。

具体实施方式
为了使本发明实施例的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施例作进一步地详细描述。
本文中描述的技术方案可用于第五代移动通信技术(5G)***，还可用于下一代移动通信***。
以下，对本发明实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
(1)网络设备，例如包括基站(例如，接入点)，可以是指接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。基站还可协调对空中接口的属性管理。例如，基站可以包括长期演进(Long Term Evolution，LTE)***或演进的LTE***(LTE-Advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括5G***中的下一代节点B(next generation node B，gNB)，本发明实施例并不限定。
(2)终端设备，包括向用户提供语音和/或数据连通性的设备，例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端设备可以经无线接入网(Radio Access Network，RAN)与核心网进行通信，与RAN交换语音和/或数据。 该终端设备可以包括用户设备(User Equipment，UE)、无线终端设备、移动终端设备、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point，AP)、远程终端设备(Remote Terminal)、接入终端设备(Access Terminal)、用户终端设备(User Terminal)、用户代理(User Agent)、或用户装备(User Device)等。例如，可以包括移动电话(或称为“蜂窝”电话)，具有移动终端设备的计算机，便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，智能穿戴式设备等。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)、智能手表、智能头盔、智能眼镜、智能手环、等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(RFID)、传感器、全球定位***(GPS)、激光扫描器等信息传感设备。
(3)波束(beam)，是一种通信资源。波束可以是宽波束，或者窄波束，或者其他类型波束。形成波束的技术可以是波束成形技术或者其他技术手段。波束成形技术可以具体为数字波束成形技术，模拟波束成形技术，混合数字/模拟波束成形技术。不同的波束可以认为是不同的资源。通过不同的波束可以发送相同的信息或者不同的信息。可选的，可以将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或多个天线端口，用于传输数据信道，控制信道和探测信号等，例如，发射波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。可以理解的是，形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。
本发明实施例中，也可以将“波束”称为“传输资源”等。也就是说，本文对于“波束”的名称不作限制，只要表达的是如上的概念即可。
(4)波束对(beam pair link)，波束对的概念建立在波束的概念上。一个波束对通常包括一个发送端的发送波束和一个接收端的接收波束。例如一个波束对可以包括基站的发送波束和UE的接收波束。
(5)本发明实施例中的术语“***”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本发明实施例中也可以将“多个”理解为“至少两个”。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
本发明实施例中，网络设备会生成多个下行信号，每个下行信号都关联随机接入配置信息，不同的下行信号可以承载在不同的下行发送波束中发送，这就实现了多波束的处理，使得本发明实施例提供的技术方案能够适用于类似于5G***的这种多波束网络。
而且本发明实施例中，不同的下行信号关联的随机接入配置信息可能是不同的，那么对于覆盖较多终端设备的下行信号，为其关联的随机接入配置信息就可以用于指示比较多的随机接入资源，而对于覆盖较少终端设备的下行信号，为其关联的随机接入配置信息就可以用于指示比较少的随机接入资源，从而使得随机接入资源能够得到较为合理的配置，避免资源浪费，提高了资源的利用率。
请参见图2，为本发明实施例的一种应用场景。在图2中包括基站和位于该基站的覆 盖范围内的多个终端设备，基站通过多个下行发送波束向位于不同方向的终端设备发送下行同步信息和***信息。
下面结合附图介绍本发明实施例提供的技术方案，在下面的介绍过程中，以将本发明提供的技术方案应用在图2所示的应用场景中为例，且以网络设备是基站为例。
请参见图3，本发明一实施例提供一种随机接入配置方法，该方法的流程描述如下。
S31、基站生成多个下行信号。
在本发明实施例中，信号承载在特定的资源中发送，这些特定的资源可以是前文中提到的“波束”。为了区分不同的波束，在下文中将承载基站发送的下行信号的波束称为基站的下行发送波束或基站的发送波束。相应的，承载基站接收的上行信号的波束就可称为基站的上行接收波束或基站的接收波束。
在一种实施方式中，下行信号是同步块(Synchronization Signal block，SS block)、同步突发(SS burst)、同步突发集(SS burst set)和***信息(System Information，SI)中的至少一种。
其中，多个下行信号中的每个下行信号都关联相应的随机接入配置信息，每个随机接入配置信息都用于指示为终端设备配置的随机接入资源，也就是说，随机接入配置信息用于为终端设备配置随机接入资源。本发明实施例中，随机接入配置信息包括用于指示终端设备进行随机接入的时间配置信息，时间配置信息包括终端设备进行随机接入的结束时间和持续时间中的至少一种，以及终端设备进行随机接入的起始时间。
因为不同的下行发送波束内的终端设备的数量可能会有所不同，例如有些下行发送波束内终端设备的数量大，而有些下行发送波束内终端设备的数量小。可参见图4，下行发送波束1内有2倍数量的终端设备，而下行发送波束2内只有1倍数量的终端设备。对于终端设备的数量多的下行发送波束，同时发起随机接入的终端设备的数量也会较多，反之，终端设备的数量较少的下行发送波束，同时发起随机接入的终端设备的数量也较少。针对这种情况，如果为所有的下行发送波束都关联相同的随机接入配置信息，那么，要么终端设备数量多的下行发送波束关联的随机接入资源不足，要么终端设备数量少的下行发送波束关联的随机接入资源又会剩余，造成资源浪费。
因此在本发明实施例中，多个下行信号所关联的随机接入配置信息是不同的，这里的不同，可以理解为多个下行信号所关联的随机接入配置信息中有部分随机接入配置信息相同而剩余的随机接入配置信息不同，或者也可以理解为多个下行信号所关联的随机接入配置信息均不相同。如果两个随机接入配置信息不同，那么这两个随机接入配置信息所指示的随机接入资源就是不同的。
请参见图5A，下行同步信息和***信息中与随机接入相关的信息主要包括帧编号、波束扫描周期、当前波束索引、以及随机接入配置信息。随机接入配置信息包括随机接入资源所在的时间配置信息、前导格式、频率位置，以及序列、功率信息等。
其中时间配置信息用于指示终端设备进行上行接入，这里的上行接入，包括随机接入、调度请求、波束优化(beam refinement)、或者***信息请求，本文在介绍时主要以随机接入为例。在时间配置信息中，包含随机接入在时间上的密度，例如，每N个帧中有K个子帧用于随机接入，以及随机接入对应的接收信号扫描周期中的至少一种，以及包括随机接入资源的起始时间和结束时间，或随机接入资源的起始时间和持续时间。起始时间或结束时间包括帧、子帧、时隙、小时隙(mini-slot)、以及正交频分复用(Orthogonal Frequency  Division Multiplexing，OFDM)符号的编号中的至少一种。一个帧、子帧、小时隙、或时隙，是由多个OFDM符号构成。例如需要帧、时隙、小时隙、和OFDM符号的编号，那么时间配置信息就可以包括帧、时隙、小时隙、和OFDM符号的编号，也就是说，时间配置信息所包括的内容可根据实际情况确定。持续时间可以用子帧数量、时隙数量、小时隙数量、OFDM符号数量中的至少一种表示。请参见图5B，为与下行信号k关联的随机接入资源和与下行信号j关联的随机接入资源的示意图，这两个随机接入资源的时间配置信息显然是不同的。在图5B中，发送波束k是承载下行信号k的下行发送波束，发送波束j是承载下行信号j的下行发送波束。
接下来介绍随机接入的帧格式，请参见图5C。一个用于随机接入的时频资源区域由N个子帧、时隙、小时隙、或者OFDM符号构成。在相同的时间位置上，可以有多块频域资源区域，各个随机接入时频资源区域在频域上可以相邻，也不相邻，即不同的随机接入时频资源区域中间有空余频域或者其它上行数据传输的频域。各个随机接入时频资源区域所占的频域宽度和/或时间宽度可以相同，也可以不相同。
例如，随机接入时频资源由N个时隙构成，本发明实施例提供三种格式，请参见图5D。其中格式1，每一个时隙由K个随机接入前导和一段保护时间构成。特别地，对于特定的时隙，该时隙内尾部为保护时间，且保护时间的结束时间和时隙的结束时间对齐。相应地，下一个时隙的头部和特定的随机接入前导的头部对齐。格式2中，同一区域内各个时隙的随机接入前导在时间上相邻，只有区域内的最后一个时隙的最后位置设置有保护时间。保护时间用于保护时间上紧挨着随机接入资源区域的其它上行数据或者下行传输数据。特别的，对于格式2，对于该随机接入资源所包含的最后一个时隙，该时隙的尾部为保护时间，且保护时间的结束时间和时隙的结束时间对齐。而对于其他时隙，不存在保护时间，且时隙的结束时间可以不和随机接入前导的结束时间对齐，相应地，这些时隙的头部可以不和特定的随机接入前导的头部对齐。在格式3中，可选地，每个时隙的开始位置有其它上行数据或者下行数据，例如下行控制信道数据或者上行控制信道数据。在格式3中，可选地，每个时隙结尾的位置有其它上行数据或者下行数据，例如上行控制信道数据或者下行控制信道数据，每个时隙结尾的位置的其它数据之前，设置有保护时间。格式3可以与格式1或格式2以任意方式结合。在另外的实施方式中，以上的随机接入时频资源区域由N个子帧、小时隙、或OFDM符号构成。以上K和N可以选任意正整数，终端设备可根据随机接入配置信息查表或者根据公式计算得到。
那么，因为本发明实施例支持多个下行信号所关联的随机接入配置信息不同，网络设备也就可以为不同的下行信号关联不同的随机接入配置信息。在一种实施方式中，网络设备可根据终端设备的数量的情况为不同的下行信号关联不同的随机接入配置信息，对于覆盖的终端设备多的下行信号，可以为其关联指示的数量较多的随机接入资源的随机接入配置信息，而对于覆盖的终端设备少的下行信号，可以为其关联指示的数量较少的随机接入资源的随机接入配置信息。在另外的实施方式中，网络设备可以根据应用场景为不同的下行信号关联不同的随机接入配置信息，例如对于覆盖范围小的下行信号，可以为其关联指示时间长度较短的随机接入资源，而对于覆盖范围大的下行信号，可以为其关联指示时间长度较长的随机接入资源。
例如请参见图5E，承载下行信号k的下行发送波束k内的终端设备数量和承载下行信号的下行发送波束j内的终端设备数量不同，基站分别在两个时间通过下行信号k和下行 信号j发送下行同步信息和***信息，其中，在下行信号k中发送的下行同步信息和***信息，与在下行信号k中发送的下行同步信息和***信息不相同。在图5E中，发送波束k就是承载下行信号k的下行发送波束，下行信号j就是承载下行信号j的下行发送波束。这里的下行同步信息和***信息不相同，可以理解为，至少是下行同步信息和***信息关联的随机接入配置信息不同。例如承载下行信号k的下行发送波束k内的终端设备数量较多，那么在下行信号k中发送的下行同步信息和***信息关联的随机接入配置信息所指示的随机接入资源较多，以便于多个终端设备进行随机接入，而承载下行信号j的下行发送波束j的终端设备数量较多，那么在下行信号j中发送的下行同步信息和***信息关联的随机接入配置信息所指示的随机接入资源较少，以避免资源浪费。通过本发明实施例所提供的技术方案，能够有效提高资源利用率。
在本发明实施例中所述的下行同步信息和***信息，可以由物理层广播信道和/或物理层数据信道发送，或者通过其它下行信道发送。在由多个下行信道发送时，多个下行信道各发送一部分。任意两个用于发送下行同步信息和***信息的下行发送波束k和下行发送波束j与基站的上行接收波束之间的对应规则满足，下行发送波束k承载的下行信号k和下行发送波束j承载的下行信号j各自关联的随机接入资源，在时间上不相交，并且不同的下行信号关联的随机接入资源在时间上的持续长度可以相同，也可以不相同。
S32、基站将多个下行信号以及多个下行信号关联的随机接入配置信息发送给终端设备，则终端设备接收该多个下行信号和多个下行信号关联的随机接入配置信息。
S33、终端设备根据接收的随机接入配置信息所指示的随机接入资源进行随机接入。
其中，与下行信号关联的随机接入配置信息可以承载在所关联的下行信号中发送，或者，与下行信号关联的随机接入配置信息可以单独发送。终端设备接收该多个下行信号和关联的随机接入配置信息后，就可以根据接收的随机接入配置信息的指示，在相应的随机接入资源上生成并发送随机接入前导，则基站就通过上行接收波束接收终端设备发送的随机接入前导。因此在图3中，以终端设备向基站发送随机接入前导来表示终端设备根据接收的随机接入配置信息所指示的随机接入资源进行随机接入。
如果基站的下行发送波束与基站的上行接收波束一一对应，那么，基站在发送下行信号后，在相对应的时间位置用对应的上行接收波束接收来自终端设备的随机接入信号即可。基站根据检测到的随机接入信号所在的随机接入资源，以及随机接入资源与下行信号的关联关系，获取各个终端设备的下行发送波束，并用该下行发送波束来给对应的终端设备发送其它下行信号。
然而，如果基站的下行发送波束和基站的上行接收波束不具备一一对应的关系，例如基站的一个下行发送波束对应基站的多个上行接收波束，基站通过多个上行接收波束分别接收信号，请参见图6A。那么在这种情况下，基站的下行信号对应时间上的多个随机接入资源。基站在不同的上行接收波束中接收终端设备发送的随机接入信号。基站根据检测到的随机接入信号所在的随机接入资源，以及随机接入资源与下行信号的关联关系，获取各个终端设备的下行发送波束，同一个上行接收波束中检测到的不同的随机接入信号，可能对应关联不同的下行信号。无论基站的下行发送波束与基站的上行接收波束之间的对应关系如何，基站的多个下行发送波束可以关联在时间位置上相同的随机接入资源。
请参见图6B，下行信号k所关联的随机接入资源和下行信号j所关联的随机接入资源在时间上有交叠，在频率或者/和序列上相互隔离。此时，同一个下行信号所关联的随机接 入资源会被一个或者多个上行接收波束接收，例如下行信号k所关联的随机接入资源被一个上行接收波束接收，而下行信号j所关联的随机接入资源被多个上行接收波束接收。请参见图6C，下行信号k所关联的随机接入资源和下行信号j所关联的随机接入资源，在时间上不连续。在图6B和图6C中，发送波束k为承载下行信号k的下行发送波束，发送波束j为承载下行信号j的下行发送波束。在其他实施方式中，不同的下行信号所关联的随机接入资源在时间上可以有交叠，并且同一个下行信号关联的随机接入资源在时间上不连续，即图6B和图6C可以结合。
本发明实施例中，同一个下行信号所关联的随机接入资源在时间上是否连续、以及多个下行信号所关联的随机接入资源在时间上是否有交叠等，可以根据基站的下行发送波束和上行接收波束是否完全对应来决定。基站可以将下行发送波束和上行接收波束之间的对应情况通过显式方式或隐式方式通知终端设备，或者终端设备可以根据随机接入资源与下行信号之间的关联关系，推断出基站的下行发送波束和上行接收波束之间的对应关系。在本发明实施例中，基站可以为不同的下行信号关联不同的随机接入配置信息，也就可以根据终端设备的数量的情况为不同的下行发送波束内的终端设备配置不同的随机接入资源，减少资源浪费，提高资源的利用率。
在图3所示的实施例中，各个下行信号是相对独立的，下面介绍另一实施例，在下面的实施例中，基站会将下行信号进行分组，更加方便管理。
请参见图7，本发明一实施例提供一种随机接入配置方法，该方法的流程描述如下。
S71、基站确定多个下行信号组。其中，不同的下行信号组关联不同的随机接入配置信息。
基站生成多个下行信号，且基站将多个下行信号分组，得到多个下行信号组，其中的每个下行信号组中包括至少一个下行信号。
在一种实施方式中，下行信号可以是SS-block，那么基站将多个下行信号分组指的是将多个SS-block进行分组，一个下行信号组包括至少一个SS-block，基站将多个下行信号组看成一个集合。在这种情况下，一个下行信号组也可以视为一个下行同步突发(SS burst)组，一个下行信号组集合可以视为下行同步突发集(SS burst set)。
在另一种实施方式中，下行信号可以是SS-burst，那么基站将多个下行信号分组指的是将多个SS-burst进行分组，一个下行信号组包括至少一个SS-burst。特别地，一个SS-burst也可构成一个下行信号组，且至少有两个下行信号组关联的随机接入配置信息不同。
在另一种实施方式中，下行信号可以是SS burst set，那么基站将多个下行信号分组指的是将多个SS burst set进行分组，一个下行信号组包括至少一个SS burst set。
在另一种实施方式中，下行信号可以是***信息，那么基站将多个下行信号分组指的是将多个***信息进行分组，一个下行信号组包括至少一个***信息。
其中，下行信号组关联的随机接入配置信息包括随机接入配置信息所指示的下行信号的时间配置索引，时间配置索引用于终端设备根据时间配置索引确定随机接入资源的开始时间、占用的频域资源、下行信号数量、以及随机接入所使用的序列资源中的至少一种。具体的，时间配置索引可以包括在时间配置信息中。终端设备接收下行信号中的***信息后，根据时间配置信息中的时间配置索引进行查表，通过查表结果或通过根据查表结果进行计算的方式确定随机接入资源的开始时间、占用的频域资源、下行信号数量、以及随机接入所使用的序列资源中的至少一种。在这种情况下，表里可以包括时间配置索引与随机 接入资源的开始时间、占用的频域资源、下行信号数量、以及随机接入所使用的序列资源中的至少一种因素之间的对应关系。或者，终端设备除了使用时间配置索引之外，还可以进一步结合下行信号索引和/或下行信号组的索引，通过查表或者根据查表结果计算的方式，得到该下行信号关联的随机接入资源的具***置，也就是确定随机接入资源的开始时间、占用的频域资源、下行信号数量、以及随机接入所使用的序列资源中的至少一种。在这种情况下，表里可以包括下行信号索引和/或下行信号组的索引、以及时间配置索引与随机接入资源的开始时间、占用的频域资源、下行信号数量、以及随机接入所使用的序列资源中的至少一种因素之间的对应关系。
或者，下行信号组关联的随机接入配置信息包括随机接入配置信息所指示的下行信号分组的随机接入的起始时间、随机接入的持续时间、随机接入的结束时间、随机接入所使用的频域资源、下行信号数量、以及随机接入所使用的序列资源中的至少一种。
在一种实施方式中，同一个下行信号组中的不同的下行信号发送的下行同步信息和***信息不完全相同，其中，一个下行信号发送的下行同步信息和***信息能够指示该下行信号关联的随机接入资源的起始时间和持续时间，或起始时间和结束时间。那么在这种实施方式中，同一个下行信号组中各个下行信号关联的随机接入配置信息也不完全相同，即，可能同一个下行信号组中不同的下行信号关联的随机接入配置信息不同。下文主要介绍同一个下行信号组中不同的下行信号关联的随机接入配置信息相同的情况。
在另一种实施方式中，同一个下行信号组中各个下行信号关联的随机接入配置信息完全相同，本文主要介绍这种情况。基站可以指定该下行信号组关联的随机接入资源的起始时间、以及其中的每个下行信号关联的随机接入资源的持续时间，或者基站可以指定该下行信号组关联的随机接入资源的结束时间和该下行信号组包括的下行信号的数量，或者基站可以指定该下行信号组关联的随机接入资源的总持续时间和该下行信号组包括的下行信号的数量。从而终端设备可以根据接收的下行信号所在的下行信号组的组索引、以及该下行信号在所在的下行信号组中的信号索引，获取与该下行信号关联的随机接入资源的时间配置信息。
本发明实施例中，基站可以根据下行发送波束内的终端设备的数量对下行信号进行分组，例如包括相同或者近似相同的终端设备数量的下行信号可以分为一组。其中，终端设备数量近似相同，可以理解为终端设备数量位于同一数量范围内。例如可事先将终端设备数量分为多个数量范围，对于终端设备数量位于同一数量范围内的下行信号，就可将其分为一组。
例如基站共生成了K1+K2个下行信号。其中承载下行信号1～下行信号K1的K1个下行发送波束内的终端设备数量都是4个，而承载剩余的K2个下行信号的K2个下行发送波束内的终端设备数量都是2个，那么基站就将下行信号1～下行信号K1分为一组，以及将剩余的K2个下行信号分为一组，请参见图8A。在图8A中将下行信号1～下行信号K1所在的下行信号组表示为第1组，将剩余的K2个下行信号所在的下行信号组表示为第2组，分别发送下行同步信息和***信息。其中的第1组包括K1个下行信号，第2组包括K2个下行信号。因为承载下行信号1～下行信号K1的K1个下行发送波束内的终端设备数量较多，则基站可以为第1组中的每个下行信号关联数量比较多的随机接入资源，例如第1组中每个下行信号关联时间上的2份随机接入资源。而承载剩余的K2个下行信号的K2个下行发送波束内的终端设备数量较少，则基站可以为第2组中的每个下行信号关联数量 比较少的随机接入资源，例如第2组中每个下行信号关联时间上的1份随机接入资源，请参见图8B。
这里的“份”，就表示随机接入资源的数量，在图8B所示的实施方式中，随机接入资源的数量差异可以通过时间来体现，数量多，可以表示为随机接入资源区域对应的时间长。在这种实施方式中，“2”和“1”可以是任意的时间长度，时间粒度可以是OFDM符号、时隙、小时隙、子帧、帧、以及前导格式的时间宽度中的任意一种。其中在本发明实施例中，如果指起始时间或者结束时间，那么这里的“帧”可理解为***帧，如果指持续时间，那么这里的“帧”可理解为无线帧。
在另一种实施方式中，随机接入资源的数量差异可以通过频率/序列资源来体现，数量多，可以表示为频域资源较宽/序列资源较多。在这种实施方式中，“2”和“1”可以是任意的频率/序列资源数量，请参见图8C。继续以如上的将K1个下行信号分为第1组，将K2个下行信号分为第2组为例，第1组中每个下行信号关联频率/序列上的2份随机接入资源，第2组中每个下行信号关联频率/序列上的1份随机接入资源。其中在图8A～图8C中的发送波束均用于承载下行信号。
S72、基站将多个下行信号组以及多个下行信号组关联的随机接入配置信息发送给终端设备，则终端设备接收该多个下行信号组和多个下行信号组关联的随机接入配置信息。
S73、终端设备根据接收的随机接入配置信息所指示的随机接入资源进行随机接入。
其中，与下行信号关联的随机接入配置信息可以承载在所关联的下行信号中发送，或者，与下行信号关联的随机接入配置信息可以单独发送。终端设备接收该多个下行信号和关联的随机接入配置信息后，就可以根据随机接入配置信息的指示，在相应的随机接入资源上生成并发送随机接入前导，则基站就通过上行接收波束接收终端设备发送的随机接入前导。因此在图7中，以终端设备向基站发送随机接入前导来表示终端设备根据接收的随机接入配置信息所指示的随机接入资源进行随机接入。
在本发明实施例中，基站除了可以为不同的下行信号关联不同的随机接入配置信息之外，还可以将下行信号进行分组，这样，除了可以减少资源浪费之外，如果时间配置信息携带的是时间配置索引，则还能降低信令开销。
