Description

波束管理方法、网络设备和终端
本申请要求在2017年6月16日提交中国专利局、申请号为201710459346.1、发明名称为“波束管理方法、网络设备和终端”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
本发明涉及通信技术领域，尤其涉及MIMO信道波束管理方法、网络设备和终端。
背景技术
鉴于MIMO(Multiple-Input Multiple-Output，多输入多输出)技术对于提高峰值速率与系统频谱利用率的重要作用，LTE(Long Term Evolution，长期演进)/LTE-A(LTE-Advanced，长期演进-技术升级版)等无线接入技术标准都是以MIMO加上OFDM(Orthogonal Frequency Division Multiplexing，正交频分复用)技术为基础构建起来的。MIMO技术的性能增益来自于多天线系统所能获得的空间自由度，因此MIMO技术在标准化发展过程中的一个最重要的演进方向便是维度的扩展。
在LTE Rel-8中，最多可以支持4层的MIMO传输。Rel-9重点对MU-MIMO(Multi-User MIMO，多用户多输入多输出)技术进行了增强，TM(Transmission Mode，传输模式)-8的MU-MIMO传输中最多可以支持4个下行数据层。Rel-10则引入支持8天线端口进一步提高了信道状态信息的空间分辨率，并进一步将SU-MIMO(Single-User MIMO，单用户多输入多输出)的传输能力扩展至最多8个数据层。Rel-13和Rel-14引入了FD-MIMO(Full-Dimension MIMO,全维度多输入多输出)技术支持到32端口，实现全维度以及垂直方向的波束赋形。
为了进一步提升MIMO技术，移动通信系统中引入大规模天线技术。对于基站，全数字化的大规模天线可以有高达128/256/512个天线振子，以及高达128/256/512个收发信机，每个天线振子连接一个收发信机。通过发送高达128/256/512个天线端口的导频信号，使得终端测量信道状态信息并反馈。对于终端，也可以配置高达32/64个天线振子的天线阵列。通过基站和终端两侧的波束赋形，获得巨大的波束赋形增益，以弥补路径损耗带来的信号衰减。尤其是在高频段通信，例如30GHz频点上，路径损耗使得无线信号的覆盖范围极其有限。通过大规模天线技术，可以将无线信号的覆盖范围扩大到可以使用的范围内。
在NR(无线接入，New Radio)系统中，为了获得基站和终端的波束赋形增益，在终 端进行上行传输时需要考虑终端的发送波束赋形。在上行波束管理过程中，基站可以为终端配置一个或多个SRS(Sounding Reference Signal，探测参考信号)资源。终端在每个SRS资源中以一个或多个发送波束(Tx beam)发送SRS信号。
为了获得最优的基站和终端波束赋形增益，在上行传输时，需要对终端的发送波束和基站的接收波束进行波束管理，以获得最优的发送波束和接收波束。在现有的协议和通信系统中，没有网络侧发给终端的波束管理指示信息。如果网络侧可以发送给终端一些发送波束指示信息，则可以更灵活有效地进行终端的发送波束扫描及基站的接收波束扫描。

具体实施方式
为了更有效地进行终端的发送波束扫描及基站的接收波束扫描，本发明实施例中的技术方案的总体思路如下：一种波束管理方法、网络设备和终端，包括：所述网络设备为终端配置SRS资源；所述网络设备向所述终端发送指示信息，其中，所述指示信息用于指示所述终端选择在所述SRS资源上发送SRS使用的发送波束。
为了更好的理解上述技术方案，下面将结合说明书附图以及具体的实施方式对上述技术方案进行详细的说明。
在本发明实施例中，所涉及到的设备包括发送设备(即网络设备)和接收设备(即终端)，发送设备与接入该发送设备的接收设备之间可以进行下行传输和上行接收。
其中，发送设备可以是基站或其他类型传输点设备，接收设备可以是用户设备(或终端)。当然不也限于上述两种设备，比如发送设备也可以是能够实现对其他终端进行配置操作的终端。也可以认为一个发送设备包含多个网络站点。网络节点可以只包括射频(如射频拉远单元(Remote Radio Unit，简称RRU))或者包括基带和射频两部分(如有源天线(Active antenna))。网络节点可以只包括基带(如基带单元(Baseband Unit，简称BBU))；也可以完全不包括任何空口层的数字/射频功能，只负责高层信号处理，把空口层的基带处理都放到有源天线。也存在其他多种网络实现可能。
终端也可称为用户设备(User Equipment，简称UE)，或者可称之为Terminal、移动台(Mobile Station，简称MS)、移动终端(Mobile Terminal)等，该终端可以经无线接入网(Radio Access Network，简称RAN)与一个或多个核心网进行通信，例如，终端可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等，例如，终端还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。本发明实施例中的终端还可以是设备与设备(Device to Device，简称D2D)终端或者机器与机器(Machine to Machine，简称M2M)终端。在本发明的实施例中对网络设备和终端不做具体限定。
在本发明实施例中，所涉及到的网络设备指定的发送波束可以是一个波束，也可以是 多个波束，在本发明的实施例中对其具体几个波束不做限制。例如网络设备通过SRI指示所述网络设备指定的发送波束，该SRI对应的SRS资源配置了多个天线端口，终端之前在该SRS资源上的SRS传输在不同天线端口使用了不同的发送波束，则该SRI指示的发送波束对应于终端之前在该SRS资源上的SRS传输在不同天线端口时使用的多个发送波束。同样地，在本发明实施例中，所涉及到的网络设备指定的发送波束对应的发送波数组可以是一个波束对应的发送波数组，也可以是多个波束对应的发送波数组，在本发明的实施例中对其具体几个波束对应的发送波数组不做限制。例如网络设备通过SRI指示所述网络设备指定的发送波束，该SRI对应的SRS资源配置了多个天线端口，终端之前在该SRS资源上的SRS传输在不同天线端口使用了不同的发送波束，则该SRI指示的发送波束对应的发送波束组对应于终端之前在该SRS资源上的SRS传输在不同天线端口时使用的多个发送波束对应的发送波束组。
参见图1，本发明实施例一提供了一种波束管理方法，应用于网络设备，所述方法包括：
S101，所述网络设备为终端配置SRS资源；
S102，所述网络设备向所述终端发送指示信息，其中，所述指示信息用于指示所述终端选择在所述SRS资源上发送SRS使用的发送波束。
基于上述步骤S102中的指示信息的不同，本实施例的波束管理方法具体可以通过如下方式实现：
方式1，所述指示信息包括用于指示零状态的信息，所述零状态表征所述终端决定自身在所述SRS资源上发送SRS使用的发送波束。例如，包括用于指示对所述终端的用于发送SRS信号的发送波束不进行限制。该指示信息的具体状态例如是表格1-表格6(指示信息的状态为二进制表示)中的000的状态(此处仅为举例但并不仅限于此，具体指示信息状态还可以采用其他数值表示，例如111、00等)。
具体地，即网络设备向终端发送指示信息后，该终端可以在网络设备当前配置的一个或多个SRS资源中使用任意的发送波束发送SRS。例如，网络设备为终端配置了多个SRS资源，终端在不同的SRS资源采用不同的发送波束发送SRS，即进行发送波束扫描(beam sweeping)。对于终端在不同的SRS资源采用不同的发送波束发送SRS，网络设备可以在接收端采用同一个接收波束(Rx beam)进行SRS的接收，从而确定出对应于该网络设备的该接收波束中的最优终端发送波束，实现终端发送波束的扫描。方式2：所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的标识信息。该指 示信息可以采用一个编码状态编码。例如，该指示信息中的一个编码状态表征所述指示信息中包括的指示所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的一个标识信息。
例如表格3中指示信息的一个编码状态1100表征指示信息中基站指定的发送波束为SRI＝5的SRS资源对应的发送波束，终端需使用该发送波束对应的发送波束组中的发送波束在所配置的SRS资源上发送SRS。
或者，所述指示信息中可以包括两部分即第一指示信息和第二指示信息，网络设备可以将所述第一指示信息和第二指示信息同时或者是先后发送给终端，第一指示信息和第二指示信息具体发送的先后关系在此不做限定。第一指示信息可以是表格6中的编码状态0，第二指示信息可以是表格1中的编码状态001-010。具体的，例如，第一指示信息的一个编码状态010表征SRI＝1，第二指示信息的一个编码状态1表征终端使用基站指示的发送波束对应的发送波束组，第一指示信息的一个编码状态010和第二指示信息的一个编码状态1共同表征指示信息中基站指定的发送波束为SRI＝1的SRS资源对应的发送波束，终端需使用该发送波束对应的发送波束组中的发送波束在所配置的SRS资源上发送SRS。
具体地，即网络设备向终端发送指示信息后，该终端在各个SRS资源上使用网络设备指示的发送波束对应的发送波束组发送SRS。网络设备指示的发送波束与终端使用的发送波数组间的映射关系可以是终端自己决定的，或者是网络设备与终端预先约定的，或者是所述网络设备通过信令发送给所述终端的。在网络设备指示的发送波束与终端使用的发送波数组间的映射关系允许存在多种映射关系的情况下，网络设备可以通过信令通知终端采用何种映射关系，或者在指示信息里隐含映射关系指示信息。如表格3中指示信息的状态1000-1010表示映射关系一，状态1011-1111表示映射关系二(映射关系具体未在表格中示出)。
一种映射关系是网络设备指示的发送波束对应一组与该发送波束宽度相近或相同的发送波束。例如网络设备当前为终端配置了N个SRS资源，终端收到指示信息后，根据网络设备指示的发送波束，采用N个与该发送波束宽度相同的发送波束发送SRS，这N个发送波束可以包含或不包含网络设备当前指示的发送波束。一个示例为网络设备指示的发送波束为标号为K的波束，当前为终端配置了4个SRS资源，则终端在4个SRS资源上分别使用第K-1，K，K+1，K+2个波束发送SRS。这种映射关系可用于分级波束扫描。考虑一个终端共有M个发送波束的场景。第一级波束扫描时基站为终端配置了N个SRS资源，则终端将这M个发送波束分成N组，除最后一个波束组有
Figure PCTCN2018086925-appb-000001
个波束外，每组有
Figure PCTCN2018086925-appb-000002
(其中
Figure PCTCN2018086925-appb-000003
表示向上取整)个波束。终端在每个波束组选择一个波 束在一个SRS资源上传输SRS。网络设备收到这些SRS后，向终端发送的指示信息包括SRI＝n(例如表格3中的SRI＝5)，即指示第n个SRS资源对应的波束，并为终端配置了
Figure PCTCN2018086925-appb-000004
个SRS资源。则终端在这

个SRS资源使用第n个SRS资源对应的波束所在波束组的波束发送SRS。这样在M比较大时，相对于为终端配置M个SRS资源进行波束扫描，进行分级波束扫描可以减少所需的SRS资源数，从而节省开销。
另一种映射关系是网络设备指示的发送波束对应一个较窄波束组，终端在终端配置的不同SRS资源采用这个波束组的波束发送SRS。在这种方式下，终端可以通过波束组的波束扫描实现更精细的局部波束扫描。这种映射关系也可以认为是一种分级波束扫描。第一级波束扫描时可以是对较宽波束的扫描。仍以第一级基站为终端配置了N个SRS资源为例。终端在每个波束组选择一个波束在一个SRS资源上传输SRS。网络设备收到这些SRS后，向终端发送的指示信息包括SRI＝n(例如表格3中的SRI＝5)，即指示第n个SRS资源对应的波束，并为终端配置了K个SRS资源。则终端在这K个SRS资源可以使用第n个SRS资源对应的波束对应的一个包含K个方向性更强(更窄)波束组的波束发送SRS。如果对于这些SRS的接收网络设备都采用了相同的接收波束，则通过这种方式，可以实现相对于第一级波束扫描更高精度的发送波束扫描。即所述网络设备可以使用同一个接收波束在所述SRS资源上接收所述SRS。
方式3，所述网络设备与所述终端预先约定所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS，指示信息包括用于指示在所述SRS资源上发送SRS的发送波束的标识信息(例如SRI，具体可参见表格1)。
网络设备向终端发送指示信息后，终端接收到指示信息，终端获得基站指示的发送波束的标识信息，并根据该标识信息，按照预先约定的规则选择各个SRS资源上使用的发送波束。该预先约定的规则即所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息。
该终端在所述SRS资源上使用所述网络设备指示的发送波束对应的发送波数组里的发送波束发送SRS。网络设备可以在接收端采用同一个接收波束(Rx beam)进行SRS的接收，从而确定出对应于该网络设备的该接收波束的最优终端发送波束，实现终端发送波束的扫描。所述同一个接收波束可以是网络设备之前选择的最优接收波束，也可以是网络设备通过其他方式确定的一个接收波束。
对于所述终端使用所述网络设备指示的发送波束与该发送波束对应的发送波束组之间的映射关系，与方式2中的映射关系相同，在此不再赘述。同样，网络设备指示的发送波束与对应的发送波束组的映射关系：由所述终端确定；或者由所述终端与所述网络设备 预先约定；或者由所述终端通过信令从所述网络设备接收。
方式4，所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息。具体可参见表4中的状态10，例如表4中的指示信息的状态10表征终端采用指定的发送波束对应的发送波束组发送SRS，但指示信息中并没有携带SRI信息。
对于网络设备指示的发送波束的标识信息(例如SRI信息)，该指示信息中不携带该标识信息，网络设备指示的发送波束的标识信息(例如SRI信息)可以通过其他的方式由网络设备发送给终端。例如基站单独向终端发送SRI信息用于表征终端使用的发送波束的标识信息。
网络设备中发送模块向终端发送指示信息后，终端接收到指示信息，终端在获得基站指示的发送波束的标识信息，所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息。
对于所述终端使用所述网络设备指示的发送波束与该发送波束对应的发送波束组之间的映射关系，与方式2中的映射关系相同，在此不再赘述。
上述方式1至方式4中，对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用同一个接收波束在所述SRS资源上接收所述SRS。
对于上述方式2至方式4，所述网络设备指示的发送波束与对应的发送波束组的映射关系：由所述终端确定；或者由所述网络设备与所述终端预先约定；或者由所述网络设备通过信令发送给所述终端。
方式5，所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的标识信息。该指示信息可以采用一个编码状态编码。例如，该指示信息中的一个编码状态表征所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的一个标识信息。例如表格3中指示信息的一个编码状态0110表征指示信息中包括基站指定的发送波束为SRI＝5的SRS资源对应的发送波束，终端需使用该发送波束在所配置的SRS资源上发送SRS。
或者，所述指示信息中可以包括两部分即第一指示信息和第二指示信息，网络设备可以将所述第一指示信息和第二指示信息同时或者是先后发送给终端，第一指示信息和第二指示信息具体发送的先后关系在此不做限定。第一指示信息可以是表格6中的编码状态1，第二指示信息可以是表格1中的编码状态001-010。具体的，例如，第一指示信息的一个编码状态010表征SRI＝1，第二指示信息的一个编码状态1表征终端使用基站指示的发送 波束，第一指示信息的一个编码状态010和第二指示信息的一个编码状态1共同表征指示信息中基站指定的发送波束为SRI＝1的SRS资源对应的发送波束，终端需使用该发送波束在所配置的SRS资源上发送SRS。
具体地，网络设备向终端发送指示信息，终端接收到指示信息，在网络设备当前配置的一个或多个SRS资源中使用网络设备指示的发送波束发送SRS。
例如，指示信息中包含网络设备指示的发送波束的标识信息，该标识信息例如是指示信息中的状态中的SRI信息，SRI用于指示终端之前发送SRS使用的SRS资源序号，具体可参见表2，例如表2中的状态001-110。终端确定了该SRI信息后，在网络设备当前配置的所有SRS资源使用该SRI对应的SRS资源使用的发送波束发送SRS。另外，多个编码状态可以表示同一个SRI的值，例如假设指示信息状态为001和010时表示SRI＝0。
指示信息用来指示终端采用何种方式选择发送波束发送SRS，网络设备指示的发送波束的标识信息可以单独发送。例如网络设备向终端额外发送SRI信息用于指示终端使用的发送波束。
对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用不同的接收波束在所述SRS资源上接收所述SRS。如果网络设备对当前配置给终端的多个SRS资源采用不同的接收波束接收，则可以实现网络设备针对网络设备指示的终端发送波束进行接收波束的扫描。
方式6，所述网络设备与所述终端预先约定所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息，所述指示信息用于在所述SRS资源上发送SRS的发送波束的标识信息(例如SRI，具体可参见表格1)。
网络设备向终端发送指示信息后，终端接收到指示信息，终端获得基站指示的发送波束的标识信息，并根据该标识信息，按照预先约定的规则选择各个SRS资源上使用的发送波束。该预先约定的规则即所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息。
对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用不同的接收波束在所述SRS资源上接收所述SRS。如果网络设备对当前配置给终端的多个SRS资源采用不同的接收波束接收，则可以实现网络设备针对网络设备指示的终端发送波束进行接收波束的扫描。
方式7，所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息。具体可参见表4中的状态01或者表5中的状态01，例如表4中的指示信息的状态01表征UE采用指定的发送波束发送SRS，但指示信息中并没有 携带SRI信息。
对于网络设备指示的发送波束的标识信息(例如SRI信息)，该指示信息中不携带该标识信息，网络设备指示的发送波束的标识信息(例如SRI信息)可以通过其他的方式由网络设备发送给终端。例如基站单独向终端发送SRI信息用于表征终端使用的发送波束的标识信息。
终端接收网络设备发送的指示信息后，根据后来获得的SRI信息，选择发送波束发送SRS信号。
对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用不同的接收波束在所述SRS资源上接收所述SRS。如果网络设备对当前配置给终端的多个SRS资源采用不同的接收波束接收，则可以实现网络设备针对网络设备指示的终端发送波束进行接收波束的扫描。
方式8，所述指示信息包括用于指示所述网络设备为所述终端配置的SRS资源进行了分组，所述网络设备对所述终端的用于发送SRS信号的发送波束不进行限制的信息；其中所述指示对所述终端的用于发送SRS信号的发送波束不进行限制的信息，即所述指示信息表征所述终端决定所述终端在所述SRS资源上发送SRS使用的发送波束。所述终端可以使用任意发送波束在所述SRS资源上发送SRS的信息。所述SRS资源的分组信息(即SRS资源如何分组)：由所述终端确定；或者由所述网络设备与所述终端预先约定；或者由所述网络设备通过信令发送给所述终端。
对于SRS资源的分组信息由所述网络设备通过信令发送给所述终端的情况，所述网络设备可以在指示信息中携带SRS资源的分组信息；或者也可以通过其他的与发送指示信息使用的发送信号不同的发送信号将SRS资源的分组信息发送给终端。终端收到这些指示信息的状态后，可以在网络设备当前配置的一个或多个SRS资源中使用任意的发送波束发送SRS。
例如网络设备与终端事先约定SRS资源的分组根据终端之前上报给网络设备的其待扫描的发送波束数和网络设备当前配置的SRS资源数确定。如果网络设备当前配置了M个SRS资源，终端之前上报给网络设备的其待扫描的发送波束数为N个，则第1、2、…、N个SRS资源为一组，第N+1、N+2、…、2N个SRS资源为一组，以此类推。
在所述指示信息包括用于指示所述网络设备为所述终端配置的SRS资源进行了分组时，不管终端是如何获知SRS资源的分组信息(例如前述SRS资源的分组信息由所述终端确定；或者由所述网络设备与所述终端预先约定；或者由所述网络设备通过信令发送给所述终端；或者其他本领域技术人员能够预见的终端获知SRS资源的分组信息的方式)， 终端都可以在相同组别的SRS资源不同资源使用不同的发送波束进行发送，从而进行发送波束的扫描。网络设备对相同组别的SRS资源使用相同的接收波束接收所述SRS，对不同组别的SRS资源使用不同的接收波束接收所述SRS。
则在这种方案下，可以实现网络设备接收波束和终端的发送波束的扫描。另一个实施例是网络设备与终端约定好SRS资源的分组规则，网络设备通过信令通知终端其对终端配置的SRS资源被分成几组。例如通知终端其对终端配置的SRS资源被分成了K组，则根据约定的SRS资源的分组规则，终端认为第1、2、…、M/(第1组，共K组)个SRS资源为一组，第N+1、N+2、…、2M/(第2组，共K组)个SRS资源为一组，以此类推。或者是指示信息的状态中包含当前为终端配置的SRS资源的分组信息。例如指示信息的状态001-010表示SRS资源只有1组，011-100表示SRS资源被分成了2组(未在表格中示出)。
对于上述各种波束管理方法的具体的实现方式，涉及到发送波束的标识信息的部分，具体可以是所述网络设备为所述终端配置的SRS资源的SRS资源指示信息SRI。
参见图2，本发明实施例二提供了一种波束管理方法，应用于终端，所述方法包括：
S201，所述终端接收网络设备发送的指示信息，其中，所述指示信息用于指示所述终端在所述网络设备为所述终端配置的SRS资源上选择用于发送SRS信号的发送波束；
S202，终端根据所述网络发送的指示信息确定在所述SRS资源上使用的发送波束，并使用所述发送波束在所述SRS资源上发送SRS。
基于上述步骤S202中的指示信息的不同，本实施例的波束管理方法具体可以通过如下方式实现：
方式1，所述指示信息包括用于指示零状态的信息，所述零状态表征所述终端决定自身在所述SRS资源上发送SRS使用的发送波束。例如，包括用于指示对所述终端的用于发送SRS信号的发送波束不进行限制。该指示信息的具体状态例如是表格1-表格6(指示信息的状态为二进制表示)中的000的状态(此处仅为举例但并不仅限于此，具体指示信息状态还可以采用其他数值表示，例如111、00等)。
具体地，即终端收到网络设备发送指示信息后，该终端可以在网络设备当前配置的一个或多个SRS资源中使用任意的发送波束发送SRS。
例如，网络设备为终端配置了多个SRS资源，终端在不同的SRS资源采用不同的发送波束发送SRS，即进行发送波束扫描(beam sweeping)。对于终端在不同的SRS资源采用不同的发送波束发送SRS，网络设备可以在接收端采用同一个接收波束(Rx beam)进行SRS的接收，从而确定出对应于该网络设备的该接收波束中的最优终端发送波束，实现 终端发送波束的扫描。
方式2：所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的标识信息。该指示信息可以采用一个编码状态编码。例如，该指示信息中的一个编码状态表征所述指示信息中包括的指示所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的一个标识信息。
例如表格3中指示信息的一个编码状态1100表征指示信息中基站指定的发送波束为SRI＝5的SRS资源对应的发送波束，终端需使用该发送波束对应一个发送波束组中的发送波束在所配置的SRS资源上发送SRS。
或者，所述指示信息中可以包括两部分即第一指示信息和第二指示信息，网络设备可以将所述第一指示信息和第二指示信息同时或者是先后发送给终端，第一指示信息和第二指示信息具体发送的先后关系在此不做限定。第一指示信息可以是表格6中的编码状态0，第二指示信息可以是表格1中的编码状态001-010。具体的，例如，第一指示信息的一个编码状态010表征SRI＝1，第二指示信息的一个编码状态1表征终端使用基站指示的发送波束对应的发送波束组，第一指示信息的一个编码状态010和第二指示信息的一个编码状态1共同表征指示信息中基站指定的发送波束为SRI＝1的SRS资源对应的发送波束，终端需使用该发送波束对应的发送波束组中的发送波束在所配置的SRS资源上发送SRS。具体地，即终端收到网络设备发送指示信息后，该终端在各个SRS资源上使用网络设备指示的发送波束对应的发送波束组发送SRS。例如，所述终端在所述SRS资源上使用所述网络设备指示的发送波束对应的发送波数组里的发送波束发送SRS。
网络设备指示的发送波束与终端使用的发送波数组间的映射关系可以是终端自己决定的，或者是终端与网络设备预先约定的，或者是所述终端通过信令从所述网络设备接收的。在网络设备指示的发送波束与终端使用的发送波数组间的映射关系允许存在多种映射关系的情况下，网络设备可以通过信令通知终端采用何种映射关系，或者在指示信息里隐含映射关系指示信息。如表格3中指示信息的状态1000-1010表示映射关系一，状态1011-1111表示映射关系二(映射关系具体未在表格中示出)。
一种映射关系是网络设备指示的发送波束对应一组与该发送波束宽度相近或相同的发送波束。例如网络设备当前为终端配置了N个SRS资源，终端收到指示信息后，根据网络设备指示的发送波束，采用N个与该发送波束宽度相同的发送波束发送SRS，这N个发送波束可以包含或不包含网络设备当前指示的发送波束。一个示例为网络设备指示的 发送波束为标号为K的波束，当前为终端配置了4个SRS资源，则终端在4个SRS资源上分别使用第K-1，K，K+1，K+2个波束发送SRS。这种映射关系可用于分级波束扫描。考虑一个终端共有M个发送波束的场景。第一级波束扫描时基站为终端配置了N个SRS资源，则终端将这M个发送波束分成N组，除最后一个波束组有
Figure PCTCN2018086925-appb-000006
个波束外，每组有
Figure PCTCN2018086925-appb-000007
(其中
Figure PCTCN2018086925-appb-000008
表示向上取整)个波束。终端在每个波束组选择一个波束在一个SRS资源上传输SRS。网络设备收到这些SRS后，向终端发送的指示信息包括SRI＝n(例如表格3中的SRI＝5)，即指示第n个SRS资源对应的波束，并为终端配置了
Figure PCTCN2018086925-appb-000009
个SRS资源。则终端在这
Figure PCTCN2018086925-appb-000010
个SRS资源使用第n个SRS资源对应的波束所在波束组的波束发送SRS。这样在M比较大时，相对于为终端配置M个SRS资源进行波束扫描，进行分级波束扫描可以减少所需的SRS资源数，从而节省开销。
另一种映射关系是网络设备指示的发送波束对应一个较窄波束组，终端在终端配置的不同SRS资源采用这个波束组的波束发送SRS。在这种方式下，终端可以通过波束组的波束扫描实现更精细的局部波束扫描。这种映射关系也可以认为是一种分级波束扫描。第一级波束扫描时可以是对较宽波束的扫描。仍以第一级基站为终端配置了N个SRS资源为例。终端在每个波束组选择一个波束在一个SRS资源上传输SRS。网络设备收到这些SRS后，向终端发送的指示信息包括SRI＝n(例如表格3中的SRI＝5)，即指示第n个SRS资源对应的波束，并为终端配置了K个SRS资源。则终端在这K个SRS资源可以使用第n个SRS资源对应的波束对应的一个包含K个方向性更强(更窄)波束组的波束发送SRS。如果对于这些SRS的接收网络设备都采用了相同的接收波束，则通过这种方式，可以实现相对于第一级波束扫描更高精度的发送波束扫描。即所述网络设备可以使用同一个接收波束在所述SRS资源上接收所述SRS。
方式3，所述网络设备与所述终端预先约定所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS，指示信息包括用于指示在所述SRS资源上发送SRS的发送波束的标识信息(例如SRI，具体可参见表格1)。
终端收到网络设备发送指示信息后，终端获得基站指示的发送波束的标识信息，并根据该标识信息，按照预先约定的规则选择各个SRS资源上使用的发送波束。该预先约定的规则即所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息。
该终端在所述SRS资源上使用所述网络设备指示的发送波束对应的发送波数组里的发送波束发送SRS。网络设备可以在接收端采用同一个接收波束(Rx beam)进行SRS的 接收，从而确定出对应于该网络设备的该接收波束的最优终端发送波束，实现终端发送波束的扫描。所述同一个接收波束可以是网络设备之前选择的最优接收波束，也可以是网络设备通过其他方式确定的一个接收波束。对于所述终端使用所述网络设备指示的发送波束与该发送波束对应的发送波束组之间的映射关系，与本实施例方式2中的映射关系相同，在此不再赘述。同样，网络设备指示的发送波束与对应的发送波束组的映射关系：由所述终端确定；或者由所述终端与所述网络设备预先约定；或者由所述终端通过信令从所述网络设备接收。
方式4，所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息。具体可参见表4中的状态10，例如表4中的指示信息的状态10表征终端采用指定的发送波束对应的发送波束组发送SRS，但指示信息中并没有携带SRI信息。
对于网络设备指示的发送波束的标识信息(例如SRI信息)，该指示信息中不携带该标识信息，网络设备指示的发送波束的标识信息(例如SRI信息)可以通过其他的方式由网络设备发送给终端。例如基站单独向终端发送SRI信息用于表征终端使用的发送波束的标识信息。
具体地，终端收到网络设备发送指示信息后，当终端再收到基站发送的SRI信息时，所述终端在所述SRS资源上使用所述网络设备指示的发送波束对应的发送波数组里的发送波束发送SRS。
对于所述终端使用所述网络设备指示的发送波束与该发送波束对应的发送波束组之间的映射关系，与本实施例方式2中的映射关系相同，在此不再赘述。同样，网络设备指示的发送波束与对应的发送波束组的映射关系：由所述终端确定；或者由所述终端与所述网络设备预先约定；或者由所述终端通过信令从所述网络设备接收。
对于方式2-方式4，所述终端在所述SRS资源上使用所述网络设备指示的发送波束对应的发送波数组里的发送波束发送SRS。
上述方式1至方式4中，对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用同一个接收波束在所述SRS资源上接收所述SRS。
对于上述方式2至方式4，所述网络设备指示的发送波束与对应的发送波束组的映射关系：由所述终端确定；或者由所述终端与所述网络设备预先约定；或者由所述终端通过信令从所述网络设备接收。
方式5，所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的标识信息。该指示信息 可以采用一个编码状态编码。例如，该指示信息中的一个编码状态表征所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的一个标识信息。例如表格3中指示信息的一个编码状态0110表征指示信息中包括基站指定的发送波束为SRI＝5的SRS资源对应的发送波束，终端需使用该发送波束在所配置的SRS资源上发送SRS。
或者，所述指示信息中可以包括两部分即第一指示信息和第二指示信息，网络设备可以将所述第一指示信息和第二指示信息同时或者是先后发送给终端，第一指示信息和第二指示信息具体发送的先后关系在此不做限定。第一指示信息可以是表格6中的编码状态1，第二指示信息可以是表格1中的编码状态001-010。具体的，例如，第一指示信息的一个编码状态010表征SRI＝1，第二指示信息的一个编码状态1表征终端使用基站指示的发送波束，第一指示信息的一个编码状态010和第二指示信息的一个编码状态1共同表征指示信息中基站指定的发送波束为SRI＝1的SRS资源对应的发送波束，终端需使用该发送波束在所配置的SRS资源上发送SRS。
具体地，终端接收网络设备发送的指示信息，在网络设备当前配置的一个或多个SRS资源中使用网络设备指示的发送波束发送SRS。
例如，指示信息中包含网络设备指示的发送波束的标识信息，该标识信息例如是指示信息中的状态中的SRI信息，SRI用于指示终端之前发送SRS使用的SRS资源序号，具体可参见表2，例如表2中的状态001-110。终端确定了该SRI信息后，在网络设备当前配置的所有SRS资源使用该SRI对应的SRS资源使用的发送波束发送SRS。另外，多个编码状态可以表示同一个SRI的值，例如假设指示信息状态为001和010时表示SRI＝0。
指示信息用来指示终端采用何种方式选择发送波束发送SRS，网络设备指示的发送波束的标识信息可以单独发送。例如网络设备向终端额外发送SRI信息用于指示终端使用的发送波束。
对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用不同的接收波束在所述SRS资源上接收所述SRS。如果网络设备对当前配置给终端的多个SRS资源采用不同的接收波束接收，则可以实现网络设备针对网络设备指示的终端发送波束进行接收波束的扫描。
方式6，所述网络设备与所述终端预先约定所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息，所述指示信息用于在所述SRS资源上发送SRS的发送波束的标识信息(例如SRI，具体可参见表格1)。
终端接收到网络设备发送的指示信息后，终端获得基站指示的发送波束的标识信息， 并根据该标识信息，按照预先约定的规则选择各个SRS资源上使用的发送波束。该预先约定的规则即所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息。
对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用不同的接收波束在所述SRS资源上接收所述SRS。如果网络设备对当前配置给终端的多个SRS资源采用不同的接收波束接收，则可以实现网络设备针对网络设备指示的终端发送波束进行接收波束的扫描。
方式7，所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息。具体可参见表4中的状态01或者表5中的状态01，例如表4中的指示信息的状态01表征UE采用指定的发送波束发送SRS，但指示信息中并没有携带SRI信息。
对于网络设备指示的发送波束的标识信息(例如SRI信息)，该指示信息中不携带该标识信息，网络设备指示的发送波束的标识信息(例如SRI信息)可以通过其他的方式由网络设备发送给终端。例如基站单独向终端发送SRI信息用于表征终端使用的发送波束的标识信息。
终端接收网络设备发送的指示信息后，根据后来获得的SRI信息，选择发送波束发送SRS信号。
对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用不同的接收波束在所述SRS资源上接收所述SRS。如果网络设备对当前配置给终端的多个SRS资源采用不同的接收波束接收，则可以实现网络设备针对网络设备指示的终端发送波束进行接收波束的扫描。
方式8，所述指示信息包括用于指示所述网络设备为所述终端配置的SRS资源进行了分组，所述网络设备对所述终端的用于发送SRS信号的发送波束不进行限制的信息；其中所述指示对所述终端的用于发送SRS信号的发送波束不进行限制的信息，即所述指示信息表征所述终端决定所述终端在所述SRS资源上发送SRS使用的发送波束。所述SRS资源的分组信息(即SRS资源如何分组)：由所述终端确定；或者由所述网络设备与所述终端预先约定；或者由所述网络设备通过信令发送给所述终端。
对于SRS资源的分组信息由所述网络设备通过信令发送给所述终端的情况，所述网络设备可以在指示信息中携带SRS资源的分组信息；或者也可以通过其他的与发送指示信息使用的发送信号不同的发送信号将SRS资源的分组信息发送给终端。终端收到这些指示信息的状态后，可以在网络设备当前配置的一个或多个SRS资源中使用任意的发送波束发 送SRS。
例如网络设备与终端事先约定SRS资源的分组根据终端之前上报给网络设备的其待扫描的发送波束数和网络设备当前配置的SRS资源数确定。如果网络设备当前配置了M个SRS资源，终端之前上报给网络设备的其待扫描的发送波束数为N个，则第1、2、…、N个SRS资源为一组，第N+1、N+2、…、2N个SRS资源为一组，以此类推。
在所述指示信息包括用于指示所述网络设备为所述终端配置的SRS资源进行了分组时，不管终端是如何获知SRS资源的分组信息(例如前述SRS资源的分组信息由所述终端确定；或者由所述网络设备与所述终端预先约定；或者由所述网络设备通过信令发送给所述终端；或者其他本领域技术人员能够预见的终端获知SRS资源的分组信息的方式)，终端都可以在相同组别的SRS资源不同资源使用不同的发送波束进行发送，从而进行发送波束的扫描。网络设备对相同组别的SRS资源使用相同的接收波束接收所述SRS，对不同组别的SRS资源使用不同的接收波束接收所述SRS。
则在这种方案下，可以实现网络设备接收波束和终端的发送波束的扫描。另一个实施例是网络设备与终端约定好SRS资源的分组规则，网络设备通过信令通知终端其对终端配置的SRS资源被分成几组。例如通知终端其对终端配置的SRS资源被分成了K组，则根据约定的SRS资源的分组规则，终端认为第1、2、…、M/(第1组，共K组)个SRS资源为一组，第N+1、N+2、…、2M/(第2组，共K组)个SRS资源为一组，以此类推。或者是指示信息的状态中包含当前为终端配置的SRS资源的分组信息。例如指示信息的状态001-010表示SRS资源只有1组，011-100表示SRS资源被分成了2组(未在表格中示出)。
对于上述各种波束管理方法的具体的实现方式，涉及到发送波束的标识信息的部分，具体可以是所述网络设备为所述终端配置的SRS资源的SRS资源指示信息SRI。
参见图3，本发明实施例三提供了一种网络设备，所述网络设备包括：
配置模块301，用于为终端配置SRS资源；
发送模块302，用于向所述终端发送指示信息，其中，所述指示信息用于指示所述终端选择在所述SRS资源上发送SRS使用的发送波束。
基于上述发送模块发送的指示信息的不同，本实施例的网络设备的具体工作方式可以包括：
方式1，所述指示信息包括用于指示零状态的信息，所述零状态表征所述终端决定自身在所述SRS资源上发送SRS使用的发送波束。例如，包括用于指示对所述终端的用于发送SRS信号的发送波束不进行限制。该指示信息的具体状态例如是表格1-表格6(指示 信息的状态为二进制表示)中的000的状态(此处仅为举例但并不仅限于此，具体指示信息状态还可以采用其他数值表示，例如111、00等)。
具体地，即网络设备中发送模块向终端发送指示信息后，该终端可以在网络设备当前配置的一个或多个SRS资源中使用任意的发送波束发送SRS。例如，网络设备为终端配置了多个SRS资源，终端在不同的SRS资源采用不同的发送波束发送SRS，即进行发送波束扫描(beam sweeping)。对于终端在不同的SRS资源采用不同的发送波束发送SRS，网络设备可以在接收端采用同一个接收波束(Rx beam)进行SRS的接收，从而确定出对应于该网络设备的该接收波束中的最优终端发送波束，实现终端发送波束的扫描。
方式2：所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的标识信息。该指示信息可以采用一个编码状态编码。例如，该指示信息中的一个编码状态表征所述指示信息中包括的指示所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的一个标识信息。例如表格3中指示信息的一个编码状态1100表征指示信息中基站指定的发送波束为SRI＝5的SRS资源对应的发送波束，终端需使用该发送波束对应一个发送波束组中的发送波束在所配置的SRS资源上发送SRS。
或者，所述指示信息中可以包括两部分即第一指示信息和第二指示信息，网络设备可以将所述第一指示信息和第二指示信息同时或者是先后发送给终端，第一指示信息和第二指示信息具体发送的先后关系在此不做限定。第一指示信息可以是表格6中的编码状态0，第二指示信息可以是表格1中的编码状态001-010。具体的，例如，第一指示信息的一个编码状态010表征SRI＝1，第二指示信息的一个编码状态1表征终端使用基站指示的发送波束对应的发送波束组，第一指示信息的一个编码状态010和第二指示信息的一个编码状态1共同表征指示信息中基站指定的发送波束为SRI＝1的SRS资源对应的发送波束，终端需使用该发送波束对应的发送波束组中的发送波束在所配置的SRS资源上发送SRS。具体地，即网络设备中发送模块向终端发送指示信息后，该终端在各个SRS资源上使用网络设备指示的发送波束对应的发送波束组发送SRS。网络设备指示的发送波束与终端使用的发送波数组间的映射关系可以是终端自己决定的，或者是网络设备与终端预先约定的，或者是所述网络设备通过信令发送给所述终端的。在网络设备指示的发送波束与终端使用的发送波数组间的映射关系允许存在多种映射关系的情况下，网络设备可以通过信令通知终端采用何种映射关系，或者在指示信息里隐含映射关系指示信息。如表格3中指示信息的状态1000-1010表示映射关系一，状态1011-1111表示映射关系二(映射关系具体未在表格 中示出)。
一种映射关系是网络设备指示的发送波束对应一组与该发送波束宽度相近或相同的发送波束。例如网络设备当前为终端配置了N个SRS资源，终端收到指示信息后，根据网络设备指示的发送波束，采用N个与该发送波束宽度相同的发送波束发送SRS，这N个发送波束可以包含或不包含网络设备当前指示的发送波束。一个示例为网络设备指示的发送波束为标号为K的波束，当前为终端配置了4个SRS资源，则终端在4个SRS资源上分别使用第K-1，K，K+1，K+2个波束发送SRS。这种映射关系可用于分级波束扫描。考虑一个终端共有M个发送波束的场景。第一级波束扫描时基站为终端配置了N个SRS资源，则终端将这M个发送波束分成N组，除最后一个波束组有
Figure PCTCN2018086925-appb-000011
个波束外，每组有
Figure PCTCN2018086925-appb-000012
(其中
Figure PCTCN2018086925-appb-000013
表示向上取整)个波束。终端在每个波束组选择一个波束在一个SRS资源上传输SRS。网络设备收到这些SRS后，向终端发送的指示信息包括SRI＝n(例如表格3中的SRI＝5)，即指示第n个SRS资源对应的波束，并为终端配置了
Figure PCTCN2018086925-appb-000014
个SRS资源。则终端在这
Figure PCTCN2018086925-appb-000015
个SRS资源使用第n个SRS资源对应的波束所在波束组的波束发送SRS。这样在M比较大时，相对于为终端配置M个SRS资源进行波束扫描，进行分级波束扫描可以减少所需的SRS资源数，从而节省开销。
另一种映射关系是网络设备指示的发送波束对应一个较窄波束组，终端在终端配置的不同SRS资源采用这个波束组的波束发送SRS。在这种方式下，终端可以通过波束组的波束扫描实现更精细的局部波束扫描。这种映射关系也可以认为是一种分级波束扫描。第一级波束扫描时可以是对较宽波束的扫描。仍以第一级基站为终端配置了N个SRS资源为例。终端在每个波束组选择一个波束在一个SRS资源上传输SRS。网络设备收到这些SRS后，向终端发送的指示信息包括SRI＝n(例如表格3中的SRI＝5)，即指示第n个SRS资源对应的波束，并为终端配置了K个SRS资源。则终端在这K个SRS资源可以使用第n个SRS资源对应的波束对应的一个包含K个方向性更强(更窄)波束组的波束发送SRS。如果对于这些SRS的接收网络设备都采用了相同的接收波束，则通过这种方式，可以实现相对于第一级波束扫描更高精度的发送波束扫描。即所述网络设备可以使用同一个接收波束在所述SRS资源上接收所述SRS。方式3，所述网络设备与所述终端预先约定所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS，指示信息包括用于指示在所述SRS资源上发送SRS的发送波束的标识信息(例如SRI，具体可参见表格1)。
网络设备中发送模块向终端发送指示信息后，终端接收到指示信息，终端获得基站指 示的发送波束的标识信息，并根据该标识信息，按照预先约定的规则选择各个SRS资源上使用的发送波束。该预先约定的规则即所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息。
该终端在所述SRS资源上使用所述网络设备指示的发送波束对应的发送波数组里的发送波束发送SRS。网络设备可以在接收端采用同一个接收波束(Rx beam)进行SRS的接收，从而确定出对应于该网络设备的该接收波束的最优终端发送波束，实现终端发送波束的扫描。所述同一个接收波束可以是网络设备之前选择的最优接收波束，也可以是网络设备通过其他方式确定的一个接收波束。
对于所述终端使用所述网络设备指示的发送波束与该发送波束对应的发送波束组之间的映射关系，与方式2中的映射关系相同，在此不再赘述。同样，网络设备指示的发送波束与对应的发送波束组的映射关系：由所述终端确定；或者由所述终端与所述网络设备预先约定；或者由所述终端通过信令从所述网络设备接收。
方式4，所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息。具体可参见表4中的状态10，例如表4中的指示信息的状态10表征终端采用指定的发送波束对应的发送波束组发送SRS，但指示信息中并没有携带SRI信息。
对于网络设备指示的发送波束的标识信息(例如SRI信息)，该指示信息中不携带该标识信息，网络设备指示的发送波束的标识信息(例如SRI信息)可以通过其他的方式由网络设备发送给终端。例如基站单独向终端发送SRI信息用于表征终端使用的发送波束的标识信息。
网络设备中发送模块向终端发送指示信息后，终端接收到指示信息，终端在获得基站指示的发送波束的标识信息，所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息。
对于所述终端使用所述网络设备指示的发送波束与该发送波束对应的发送波束组之间的映射关系，与方式2中的映射关系相同，在此不再赘述。
上述方式1至方式4中，对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用同一个接收波束在所述SRS资源上接收所述SRS。
对于上述方式2至方式4，所述网络设备指示的发送波束与对应的发送波束组的映射关系：由所述终端确定；或者由所述网络设备与所述终端预先约定；或者由所述网络设备通过信令发送给所述终端。
方式5，所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束在所 述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的标识信息。该指示信息可以采用一个编码状态编码。例如，该指示信息中的一个编码状态表征所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的一个标识信息。例如表格3中指示信息的一个编码状态0110表征指示信息中包括基站指定的发送波束为SRI＝5的SRS资源对应的发送波束，终端需使用该发送波束在所配置的SRS资源上发送SRS
或者，所述指示信息中可以包括两部分即第一指示信息和第二指示信息，网络设备可以将所述第一指示信息和第二指示信息同时或者是先后发送给终端，第一指示信息和第二指示信息具体发送的先后关系在此不做限定。第一指示信息可以是表格6中的编码状态1，第二指示信息可以是表格1中的编码状态001-010。具体的，例如，第一指示信息的一个编码状态010表征SRI＝1，第二指示信息的一个编码状态1表征终端使用基站指示的发送波束，第一指示信息的一个编码状态010和第二指示信息的一个编码状态1共同表征指示信息中基站指定的发送波束为SRI＝1的SRS资源对应的发送波束，终端需使用该发送波束在所配置的SRS资源上发送SRS。具体地，网络设备中的发送模块向终端发送指示信息，终端接收到指示信息，在网络设备当前配置的一个或多个SRS资源中使用网络设备指示的发送波束发送SRS。
例如，指示信息中包含网络设备指示的发送波束的标识信息，该标识信息例如是指示信息中的状态中的SRI信息，SRI用于指示终端之前发送SRS使用的SRS资源序号，具体可参见表2，例如表2中的状态001-110。终端确定了该SRI信息后，在网络设备当前配置的所有SRS资源使用该SRI对应的SRS资源使用的发送波束发送SRS。另外，多个编码状态可以表示同一个SRI的值，例如假设指示信息状态为001和010时表示SRI＝0。
指示信息用来指示终端采用何种方式选择发送波束发送SRS，网络设备指示的发送波束的标识信息可以单独发送。例如网络设备向终端额外发送SRI信息用于指示终端使用的发送波束。
对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用不同的接收波束在所述SRS资源上接收所述SRS。如果网络设备对当前配置给终端的多个SRS资源采用不同的接收波束接收，则可以实现网络设备针对网络设备指示的终端发送波束进行接收波束的扫描。
方式6，所述网络设备与所述终端预先约定所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息，所述指示信息用于在所述SRS资源上发送SRS的发送波束的标识信息(例如SRI，具体可参见表格1)。
网络设备中的发送模块向终端发送指示信息后，终端接收到指示信息，终端获得基站指示的发送波束的标识信息，并根据该标识信息，按照预先约定的规则选择各个SRS资源上使用的发送波束。该预先约定的规则即所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息。
对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用不同的接收波束在所述SRS资源上接收所述SRS。如果网络设备对当前配置给终端的多个SRS资源采用不同的接收波束接收，则可以实现网络设备针对网络设备指示的终端发送波束进行接收波束的扫描。
方式7，所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息。具体可参见表4中的状态01或者表5中的状态01，例如表4中的指示信息的状态01表征UE采用指定的发送波束发送SRS，但指示信息中并没有携带SRI信息。
对于网络设备指示的发送波束的标识信息(例如SRI信息)，该指示信息中不携带该标识信息，网络设备指示的发送波束的标识信息(例如SRI信息)可以通过其他的方式由网络设备发送给终端。例如基站单独向终端发送SRI信息用于表征终端使用的发送波束的标识信息。
网络设备中的发送模块向终端发送指示信息后，终端接收网络设备发送的指示信息后，根据后来获得的SRI信息，选择发送波束发送SRS信号。
对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用不同的接收波束在所述SRS资源上接收所述SRS。如果网络设备对当前配置给终端的多个SRS资源采用不同的接收波束接收，则可以实现网络设备针对网络设备指示的终端发送波束进行接收波束的扫描。
方式8，所述指示信息包括用于指示所述网络设备为所述终端配置的SRS资源进行了分组，所述网络设备对所述终端的用于发送SRS信号的发送波束不进行限制的信息；其中所述指示对所述终端的用于发送SRS信号的发送波束不进行限制的信息，即所述指示信息表征所述终端决定所述终端在所述SRS资源上发送SRS使用的发送波束。所述SRS资源的分组信息(即SRS资源如何分组)：由所述终端确定；或者由所述网络设备与所述终端预先约定；或者由所述网络设备通过信令发送给所述终端。
对于SRS资源的分组信息由所述网络设备通过信令发送给所述终端的情况，所述网络设备可以在指示信息中携带SRS资源的分组信息；或者也可以通过其他的与发送指示信息使用的发送信号不同的发送信号将SRS资源的分组信息发送给终端。网络设备中的发送 模块向终端发送指示信息，终端收到这些指示信息的状态后，可以在网络设备当前配置的一个或多个SRS资源中使用任意的发送波束发送SRS。
例如网络设备与终端事先约定SRS资源的分组根据终端之前上报给网络设备的其待扫描的发送波束数和网络设备当前配置的SRS资源数确定。如果网络设备当前配置了M个SRS资源，终端之前上报给网络设备的其待扫描的发送波束数为N个，则第1、2、…、N个SRS资源为一组，第N+1、N+2、…、2N个SRS资源为一组，以此类推。
在所述指示信息包括用于指示所述网络设备为所述终端配置的SRS资源进行了分组时，不管终端是如何获知SRS资源的分组信息(例如前述SRS资源的分组信息由所述终端确定；或者由所述网络设备与所述终端预先约定；或者由所述网络设备通过信令发送给所述终端；或者其他本领域技术人员能够预见的终端获知SRS资源的分组信息的方式)，终端都可以在相同组别的SRS资源不同资源使用不同的发送波束进行发送，从而进行发送波束的扫描。网络设备对相同组别的SRS资源使用相同的接收波束接收所述SRS，对不同组别的SRS资源使用不同的接收波束接收所述SRS。
则在这种方案下，可以实现网络设备接收波束和终端的发送波束的扫描。另一个实施例是网络设备与终端约定好SRS资源的分组规则，网络设备通过信令通知终端其对终端配置的SRS资源被分成几组。例如通知终端其对终端配置的SRS资源被分成了K组，则根据约定的SRS资源的分组规则，终端认为第1、2、…、M/(第1组，共K组)个SRS资源为一组，第N+1、N+2、…、2M/(第2组，共K组)个SRS资源为一组，以此类推。或者是指示信息的状态中包含当前为终端配置的SRS资源的分组信息。例如指示信息的状态001-010表示SRS资源只有1组，011-100表示SRS资源被分成了2组(未在表格中示出)。
对于上述各种波束管理方法的具体的实现方式，涉及到发送波束的标识信息的部分，具体可以是所述网络设备为所述终端配置的SRS资源的SRS资源指示信息SRI。
参见图4，本发明实施例四提供了一种终端，所述终端包括：
接收模块401，用于接收网络设备发送的指示信息，其中，所述指示信息用于指示所述终端在所述网络设备为所述终端配置的SRS资源上选择用于发送SRS信号的发送波束；
发送模块402，用于根据所述网络发送的指示信息确定在所述SRS资源上使用的发送波束，使用所述发送波束在所述SRS资源上发送SRS。
基于上述接收模块401接收到的指示信息的不同，本实施例的终端的工作方式具体可以通过如下方式实现：
方式1，所述指示信息包括用于指示零状态的信息，所述零状态表征所述终端决定自 身在所述SRS资源上发送SRS使用的发送波束。例如，包括用于指示对所述终端的用于发送SRS信号的发送波束不进行限制。该指示信息的具体状态例如是表格1-表格6(指示信息的状态为二进制表示)中的000的状态(此处仅为举例但并不仅限于此，具体指示信息状态还可以采用其他数值表示，例如111、00等)。
具体地，即终端中的接收模块收到网络设备发送指示信息后，该终端中的发送模块可以在网络设备当前配置的一个或多个SRS资源中使用任意的发送波束发送SRS。
例如，网络设备为终端配置了多个SRS资源，终端在不同的SRS资源采用不同的发送波束发送SRS，即进行发送波束扫描(beam sweeping)。对于终端在不同的SRS资源采用不同的发送波束发送SRS，网络设备可以在接收端采用同一个接收波束(Rx beam)进行SRS的接收，从而确定出对应于该网络设备的该接收波束中的最优终端发送波束，实现终端发送波束的扫描。
方式2：所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的标识信息。该指示信息可以采用一个编码状态编码。例如，该指示信息中的一个编码状态表征所述指示信息中包括的指示所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的一个标识信息。例如表格3中指示信息的一个编码状态1100表征指示信息中基站指定的发送波束为SRI＝5的SRS资源对应的发送波束，终端需使用该发送波束对应一个发送波束组中的发送波束在所配置的SRS资源上发送SRS。
或者，所述指示信息中可以包括两部分即第一指示信息和第二指示信息，网络设备可以将所述第一指示信息和第二指示信息同时或者是先后发送给终端，第一指示信息和第二指示信息具体发送的先后关系在此不做限定。第一指示信息可以是表格6中的编码状态0，第二指示信息可以是表格1中的编码状态001-010。具体的，例如，第一指示信息的一个编码状态010表征SRI＝1，第二指示信息的一个编码状态1表征终端使用基站指示的发送波束对应的发送波束组，第一指示信息的一个编码状态010和第二指示信息的一个编码状态1共同表征指示信息中基站指定的发送波束为SRI＝1的SRS资源对应的发送波束，终端需使用该发送波束对应的发送波束组中的发送波束在所配置的SRS资源上发送SRS。具体地，即终端中的接收模块收到网络设备发送指示信息后，该终端在各个SRS资源上使用网络设备指示的发送波束对应的发送波束组发送SRS。例如，所述终端中的发送模块在所述SRS资源上使用所述网络设备指示的发送波束对应的发送波数组里的发送波束发送SRS。
网络设备指示的发送波束与终端使用的发送波数组间的映射关系可以是终端自己决 定的，或者是终端与网络设备预先约定的，或者是所述终端通过信令从所述网络设备接收的。在网络设备指示的发送波束与终端使用的发送波数组间的映射关系允许存在多种映射关系的情况下，网络设备可以通过信令通知终端采用何种映射关系，或者在指示信息里隐含映射关系指示信息。如表格3中指示信息的状态1000-1010表示映射关系一，状态1011-1111表示映射关系二(映射关系具体未在表格中示出)。
一种映射关系是网络设备指示的发送波束对应一组与该发送波束宽度相近或相同的发送波束。例如网络设备当前为终端配置了N个SRS资源，终端收到指示信息后，根据网络设备指示的发送波束，采用N个与该发送波束宽度相同的发送波束发送SRS，这N个发送波束可以包含或不包含网络设备当前指示的发送波束。一个示例为网络设备指示的发送波束为标号为K的波束，当前为终端配置了4个SRS资源，则终端在4个SRS资源上分别使用第K-1，K，K+1，K+2个波束发送SRS。这种映射关系可用于分级波束扫描。考虑一个终端共有M个发送波束的场景。第一级波束扫描时基站为终端配置了N个SRS资源，则终端将这M个发送波束分成N组，除最后一个波束组有

个波束外，每组有
Figure PCTCN2018086925-appb-000017
(其中
Figure PCTCN2018086925-appb-000018
表示向上取整)个波束。终端在每个波束组选择一个波束在一个SRS资源上传输SRS。网络设备收到这些SRS后，向终端发送的指示信息包括SRI＝n(例如表格3中的SRI＝5)，即指示第n个SRS资源对应的波束，并为终端配置了
Figure PCTCN2018086925-appb-000019
个SRS资源。则终端在这
Figure PCTCN2018086925-appb-000020
个SRS资源使用第n个SRS资源对应的波束所在波束组的波束发送SRS。这样在M比较大时，相对于为终端配置M个SRS资源进行波束扫描，进行分级波束扫描可以减少所需的SRS资源数，从而节省开销。
另一种映射关系是网络设备指示的发送波束对应一个较窄波束组，终端在终端配置的不同SRS资源采用这个波束组的波束发送SRS。在这种方式下，终端可以通过波束组的波束扫描实现更精细的局部波束扫描。这种映射关系也可以认为是一种分级波束扫描。第一级波束扫描时可以是对较宽波束的扫描。仍以第一级基站为终端配置了N个SRS资源为例。终端在每个波束组选择一个波束在一个SRS资源上传输SRS。网络设备收到这些SRS后，向终端发送的指示信息包括SRI＝n(例如表格3中的SRI＝5)，即指示第n个SRS资源对应的波束，并为终端配置了K个SRS资源。则终端在这K个SRS资源可以使用第n个SRS资源对应的波束对应的一个包含K个方向性更强(更窄)波束组的波束发送SRS。如果对于这些SRS的接收网络设备都采用了相同的接收波束，则通过这种方式，可以实现相对于第一级波束扫描更高精度的发送波束扫描。即所述网络设备可以使用同一个接收波束在所述SRS资源上接收所述SRS。
方式3，所述网络设备与所述终端预先约定所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS，指示信息包括用于指示在所述SRS资源上发送SRS的发送波束的标识信息(例如SRI，具体可参见表格1)。
终端中的接收模块收到网络设备发送指示信息后，终端获得基站指示的发送波束的标识信息，并根据该标识信息，按照预先约定的规则选择各个SRS资源上使用的发送波束。该预先约定的规则即所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息。
该终端中的发送模块在所述SRS资源上使用所述网络设备指示的发送波束对应的发送波数组里的发送波束发送SRS。网络设备可以在接收端采用同一个接收波束(Rx beam)进行SRS的接收，从而确定出对应于该网络设备的该接收波束的最优终端发送波束，实现终端发送波束的扫描。所述同一个接收波束可以是网络设备之前选择的最优接收波束，也可以是网络设备通过其他方式确定的一个接收波束。
对于所述终端使用所述网络设备指示的发送波束与该发送波束对应的发送波束组之间的映射关系，与本实施例方式2中的映射关系相同，在此不再赘述。同样，网络设备指示的发送波束与对应的发送波束组的映射关系：由所述终端确定；或者由所述终端与所述网络设备预先约定；或者由所述终端通过信令从所述网络设备接收。
方式4，所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束对应的发送波束组中的发送波束在所述SRS资源上发送SRS的信息。具体可参见表4中的状态10，例如表4中的指示信息的状态10表征终端采用指定的发送波束对应的发送波束组发送SRS，但指示信息中并没有携带SRI信息。
对于网络设备指示的发送波束的标识信息(例如SRI信息)，该指示信息中不携带该标识信息，网络设备指示的发送波束的标识信息(例如SRI信息)可以通过其他的方式由网络设备发送给终端。例如基站单独向终端发送SRI信息用于表征终端使用的发送波束的标识信息。
具体地，终端中的接收模块收到网络设备发送指示信息后，当终端再收到基站发送的SRI信息时，所述终端中的发送模块在所述SRS资源上使用所述网络设备指示的发送波束对应的发送波数组里的发送波束发送SRS。
对于所述终端使用所述网络设备指示的发送波束与该发送波束对应的发送波束组之间的映射关系，与本实施例方式2中的映射关系相同，在此不再赘述。同样，网络设备指示的发送波束与对应的发送波束组的映射关系：由所述终端确定；或者由所述终端与所述网络设备预先约定；或者由所述终端通过信令从所述网络设备接收。
对于方式2-方式4，所述终端在所述SRS资源上使用所述网络设备指示的发送波束对应的发送波数组里的发送波束发送SRS。
对于上述方式1至方式4，对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用同一个接收波束在所述SRS资源上接收所述SRS。
对于上述方式2至方式4，所述网络设备指示的发送波束与对应的发送波束组的映射关系：由所述终端确定；或者由所述终端与所述网络设备预先约定；或者由所述终端通过信令从所述网络设备接收。
方式5，所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的标识信息。该指示信息可以采用一个编码状态编码。例如，该指示信息中的一个编码状态表征所述指示信息包括用于指示所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息和所述网络设备指示的发送波束的一个标识信息。例如表格3中指示信息的一个编码状态0110表征指示信息中包括包括基站指定的发送波束为SRI＝5的SRS资源对应的发送波束，终端需使用该发送波束在所配置的SRS资源上发送SRS。
或者，所述指示信息中可以包括两部分即第一指示信息和第二指示信息，网络设备可以将所述第一指示信息和第二指示信息同时或者是先后发送给终端，第一指示信息和第二指示信息具体发送的先后关系在此不做限定。第一指示信息可以是表格6中的编码状态1，第二指示信息可以是表格1中的编码状态001-010。具体的，例如，第一指示信息的一个编码状态010表征SRI＝1，第二指示信息的一个编码状态1表征终端使用基站指示的发送波束，第一指示信息的一个编码状态010和第二指示信息的一个编码状态1共同表征指示信息中基站指定的发送波束为SRI＝1的SRS资源对应的发送波束，终端需使用该发送波束在所配置的SRS资源上发送SRS。
具体地，终端中的接收模块接收网络设备发送的指示信息，在网络设备当前配置的一个或多个SRS资源中使用网络设备指示的发送波束发送SRS。
例如，指示信息中包含网络设备指示的发送波束的标识信息，该标识信息例如是指示信息中的状态中的SRI信息，SRI用于指示终端之前发送SRS使用的SRS资源序号，具体可参见表2，例如表2中的状态001-110。终端确定了该SRI信息后，在网络设备当前配置的所有SRS资源使用该SRI对应的SRS资源使用的发送波束发送SRS。另外，多个编码状态可以表示同一个SRI的值，例如假设指示信息状态为001和010时表示SRI＝0。
指示信息用来指示终端采用何种方式选择发送波束发送SRS，网络设备指示的发送波束的标识信息可以单独发送。例如网络设备向终端额外发送SRI信息用于指示终端使用的 发送波束。
对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用不同的接收波束在所述SRS资源上接收所述SRS。如果网络设备对当前配置给终端的多个SRS资源采用不同的接收波束接收，则可以实现网络设备针对网络设备指示的终端发送波束进行接收波束的扫描。
方式6，所述网络设备与所述终端预先约定所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息，所述指示信息用于在所述SRS资源上发送SRS的发送波束的标识信息(例如SRI，具体可参见表格1)。
终端中的接收模块接收到网络设备发送的指示信息后，终端获得基站指示的发送波束的标识信息，并根据该标识信息，按照预先约定的规则选择各个SRS资源上使用的发送波束。该预先约定的规则即所述终端使用所述网络设备指示的发送波束在所述SRS资源上发送SRS的信息。
对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用不同的接收波束在所述SRS资源上接收所述SRS。如果网络设备对当前配置给终端的多个SRS资源采用不同的接收波束接收，则可以实现网络设备针对网络设备指示的终端发送波束进行接收波束的扫描。

终端中的接收模块接收网络设备发送的指示信息后，根据后来获得的SRI信息，选择发送波束发送SRS信号。
对于所述终端在所述SRS资源上发送的SRS，所述网络设备使用不同的接收波束在所述SRS资源上接收所述SRS。如果网络设备对当前配置给终端的多个SRS资源采用不同的接收波束接收，则可以实现网络设备针对网络设备指示的终端发送波束进行接收波束的扫描。
方式8，所述指示信息包括用于指示所述网络设备为所述终端配置的SRS资源进行了 分组，所述网络设备对所述终端的用于发送SRS信号的发送波束不进行限制的信息；其中所述指示对所述终端的用于发送SRS信号的发送波束不进行限制的信息，即所述指示信息表征所述终端决定所述终端在所述SRS资源上发送SRS使用的发送波束。所述SRS资源的分组信息(即SRS资源如何分组)：由所述终端确定；或者由所述网络设备与所述终端预先约定；或者由所述网络设备通过信令发送给所述终端。
对于SRS资源的分组信息由所述网络设备通过信令发送给所述终端的情况，所述网络设备可以在指示信息中携带SRS资源的分组信息；或者也可以通过其他的与发送指示信息使用的发送信号不同的发送信号将SRS资源的分组信息发送给终端。终端收到这些指示信息的状态后，终端中的发送模块可以在网络设备当前配置的一个或多个SRS资源中使用任意的发送波束发送SRS。
例如网络设备与终端事先约定SRS资源的分组根据终端之前上报给网络设备的其待扫描的发送波束数和网络设备当前配置的SRS资源数确定。如果网络设备当前配置了M个SRS资源，终端之前上报给网络设备的其待扫描的发送波束数为N个，则第1、2、…、N个SRS资源为一组，第N+1、N+2、…、2N个SRS资源为一组，以此类推。
在所述指示信息包括用于指示所述网络设备为所述终端配置的SRS资源进行了分组时，不管终端是如何获知SRS资源的分组信息(例如前述SRS资源的分组信息由所述终端确定；或者由所述网络设备与所述终端预先约定；或者由所述网络设备通过信令发送给所述终端；或者其他本领域技术人员能够预见的终端获知SRS资源的分组信息的方式)，终端都可以在相同组别的SRS资源不同资源使用不同的发送波束进行发送，从而进行发送波束的扫描。网络设备对相同组别的SRS资源使用相同的接收波束接收所述SRS，对不同组别的SRS资源使用不同的接收波束接收所述SRS。
则在这种方案下，可以实现网络设备接收波束和终端的发送波束的扫描。另一个实施例是网络设备与终端约定好SRS资源的分组规则，网络设备通过信令通知终端其对终端配置的SRS资源被分成几组。例如通知终端其对终端配置的SRS资源被分成了K组，则根据约定的SRS资源的分组规则，终端认为第1、2、…、M/(第1组，共K组)个SRS资源为一组，第N+1、N+2、…、2M/(第2组，共K组)个SRS资源为一组，以此类推。或者是指示信息的状态中包含当前为终端配置的SRS资源的分组信息。例如指示信息的状态001-010表示SRS资源只有1组，011-100表示SRS资源被分成了2组(未在表格中示出)。
对于上述各种波束管理方法的具体的实现方式，涉及到发送波束的标识信息的部分，具体可以是所述网络设备为所述终端配置的SRS资源的SRS资源指示信息SRI。

本发明的实施例六提供了一种计算机可读存储介质，其上存储有计算机程序，其特征在于：所述计算机程序被处理器执行时实现如实施例一或实施例二中所述方法的步骤。
