具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述。
本发明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，简称为“GSM”)系统、码分多址(Code Division Multiple Access，简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)系统、通用分组无线业务(General Packet Radio Service，简称为“GPRS”)、长期演进(Long Term Evolution，简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex，简称为“FDD”)系统、LTE时分双工(Time Division Duplex，简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System，简称为“UMTS”)、全球互联微波接入(Worldwide Interoperability for Microwave Access，简称为“WiMAX”)通信系统、未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)或未来的5G系统等。
图1示出了本发明实施例应用的无线通信系统100。该无线通信系统100可以包括至少一个网络设备110。网络设备100可以是与终端设备通信的设备。每个网络设备100可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备(例如UE)进行通信。该网络设备100可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备、未来5G网络中的网络侧设备、传输点或者未来演进的PLMN中的网络设备等。
该无线通信系统100还包括位于网络设备110覆盖范围内的多个终端设备120。该终端设备120可以是移动的或固定的。该终端设备120可以指接入终端、用户设备(User Equipment，UE)、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。接入终端可以是蜂窝电话、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PLMN中的终端设备等。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本发明实施例对此不做限定。
可选地，该无线通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本发明实施例不限于此。
无线通信系统100可以采用多波束技术。具体地，对于下行链路，网络设备可以具有多个下行发射波束(DL Tx Beam)，终端设备可以具有多个下行接收波束(DL Rx Beam)；对于上行链路，终端设备可以具有多个上行发射波束(UL Tx Beam)，网络设备可以具有多个上行接收波束(UL Rx Beam)。
为了便于理解，这里假设终端设备具有U1个上行发射波束和D1个下行接收波束，网络设备具有U2个上行接收波束和D2个下行发射波束，其中， U1、U2、D1和D2均为大于1的整数。
在通信过程中，网络设备和终端设备需要分别确定当前用于下行传输的波束和当前用于上行传输的波束，由此造成的信令开销较大，设备负担较重。
具体地，对于用于下行传输的波束的选择，网络设备需要采用所有下行发射波束中的每个下行发射波束向终端设备发送D1个下行上行信号。终端设备可以采用D1个下行接收波束分别测量网络设备采用同一个下行发射波束发送的D1个下行上行信号，得到D1个测量值。这样，终端设备需要进行D1×D2次测量，得到D1×D2个测量值，并根据得到的测量值集合，从所有的下行发射波束和下行接收波束中确定当前采用的下行发射波束和下行接收波束。
类似地，对于用于上行传输的波束的选择，终端设备需要采用所有上行发射波束中的每个上行发射波束向网络设备发送上行信号。网络设备需要采用所有上行接收波束中的每个上行接收波束对终端设备的每个上行发射波束进行一次测量，得到多个测量值，并根据得到的测量值集合，从多个上行发射波束和上行接收波束中确定当前采用的上行发射波束和上行接收波束。
为了降低波束选择造成的信令开销和设备负担，可以确定发射/接收波束对应性是否成立。如果发射/接收波束对应性成立，则可以根据用于上行传输的波束确定用于下行传输的波束，或根据用于下行传输的波束确定用于上行传输的波束。这样，网络设备和终端设备只需要进行一个链路方向上的波束选择，即可得到用于另一个链路方向上的数据传输的波束，从而降低信令开销和设备负担。
可选地，如果以下条件中的至少一个满足，则终端设备处的发射/接收上行波束对应性成立：
1、终端设备能够根据该终端设备对一个或多个DL Rx Beam的测量，确定用于上行传输的UL Tx Beam；
2、终端设备能够基于网络设备的指示，确定用于下行传输的DL Rx Beam，其中，网络设备的指示是基于对于终端设备的一个或多个UL Tx Beam进行测量得到的。
可选地，如果以下条件中的至少一个满足，则网络设备处的发射/接收上行波束对应性成立：
1、网络设备能够根据终端设备对网络设备的一个或多个DL Tx Beam的 测量，确定用于上行传输的UL Rx Beam；
2、网络设备能够基于网络设备对一个或多个UL Rx Beam的测量，确定用于下行传输的DL Tx Beam。
下面将结合具体例子详细描述本发明实施例提供的确定发射/接收波束对应性的技术方案。
图2示出了本发明实施例提供的无线通信方法200。该无线通信方法200可以应用于图1所示的无线通信系统100，但本发明实施例不限于此。

假设终端设备具有U1个上行发射波束和D1个下行接收波束，网络设备具有U2个上行接收波束和D2个下行发射波束，其中，该U1个上行发射波束和D1个下行接收波束之间可以具有某种映射关系，该映射关系可以是一对一映射、一对多映射或多对多映射。例如，该终端设备可以包括U1个波束，该U1个波束中的每个波束既可以作为上行发射波束，也可以作为下行接收波束，此时，D1＝U1并且每个上行发射波束映射到的下行接收波束为该上行发射波束本身，但本发明实施例不限于此。
可选地，该多个上行发射波束的数量可以为终端设备需要测量的上行发射波束的数量，该多个上行发射波束可以为该终端设备的U1个上行发射波束中的部分或全部上行发射波束，本发明实施例对此不做限定。
可选地，终端设备可以采用U1个上行发射波束中的每个上行发射波束向网络设备发送至少一个上行信号。可选地，终端设备采用不同的上行发射波束向网络设备发送的上行信号数量可以相同或不同。为了便于理解，下面以该终端设备可以采用每个上行发射波束向网络设备发送U2个上行信号为例进行描述，但本发明实施例不限于此。
可选地，终端设备采用不同的上行发射波束向网络设备发送的上行信号类型可以相同或不同，并且终端设备采用同一个上行发射波束向网络设备发送的至少一个上行信号可以为相同类型的上行信号或不同类型的上行信号，例如，终端设备可以采用每个上行发射波束向网络设备重复发送至少一次上行信号，但本发明实施例对此不做限定。

这里的波束测量专用上行信号可以是专门用于进行波束测量的上行信号。可选地，该终端设备发送的上行信号也可以包括其它类型的信号，本发明实施例对此不做限定。
在S210中，终端设备向网络设备发送上行信号的配置可以是协议定义的，也可以是终端设备的原有配置，例如是终端设备上次进行波束选择或确定发射/接收波束对应性的过程中采用的配置，也可以是网络设备动态配置的，本发明实施例对此不做限定。
可选地，在S210之前，该方法200还包括：网络设备向终端设备发送配置指示信息，该配置指示信息用于指示该终端设备发送上行信号的配置。此时，该终端设备在接收到网络设备发送的该配置指示信息时，可以根据该配置指示信息，采用多个上行发射波束中的每个上行发射波束向网络设备发送上行信号。
具体地，若该配置指示信息指示了该终端设备发送上行信号所需的所有配置参数，则在S210中，该终端设备可以采用该配置指示信息指示的配置参数发送上行信号。可选地，若该配置指示信息指示了该终端设备发送上行信号所需的部分配置参数，则在S210中，该终端设备还可以根据协议规定或原有配置确定该配置指示信息未指示的配置参数，但本发明实施例不限于此。
可选地，该配置指示信息可以用于指示下列配置参数中的至少一种：上行发射波束的测量次序、上行发射波束的重复测量次数、上行发射波束与上行信号之间的对应关系、上行发射波束与传输资源之间的对应关系。
可选地，该配置指示信息可以用于指示上行发射波束的测量次序，即该终端设备采用该多个上行发射波束发送上行信号的次序。可选地，该配置指示信息也可以用于指示上行发射波束的重复测量次数。具体地，上行发射波束的重复测量次数用于表示该终端设备采用该上行发射波束向网络设备发送的上行信号数量。可选地，该多个上行发射波束中不同的上行发射波束的重复测量次数可以相同或不同，本发明实施例对此不做限定。可选地，该配置指示信息也可以用于指示该多个上行发射波束与多个上行信号之间的对应关系。此时，终端设备可以根据该上行发射波束与上行信号之间的对应关 系，确定采用该多个上行发射波束中每个上行发射波束发送的上行信号的类型。可选地，任意两个不同的上行发射波束可以用于发送相同或不同的上行信号，但本发明实施例不限于此。可选地，该配置指示信息也可以用于指示该多个上行发射波束与传输资源之间的对应关系。此时，终端设备可以根据上行发射波束与传输资源之间的对应关系，确定采用该多个上行发射波束中每个上行发射波束发送上行信号时对应的传输资源，并在该对应的传输资源上采用该每个上行发射波束发送上行信号。可选地，终端设备在采用任意两个不同的上行发射波束发送上行信号时可以占用相同或不同的传输资源，但本发明实施例不限于此。
可选地，该配置指示信息也可以用于指示其它配置参数，本发明实施例对此不做限定。
为了便于理解，下面以终端设备采用每个上行发射波束向网络设备发送U2个上行信号为例进行描述，但本发明实施例不限于此。
S220，网络设备可以采用多个上行接收波束测量该终端设备采用多个上行发射波束中每个上行发射波束发送的上行信号，得到上行测量结果。
该多个上行接收波束的数量可以为网络设备需要测量的上行接收波束的数量。该多个上行接收波束可以为该网络设备的U2个上行接收波束中的部分或全部上行接收信号，本发明实施例对此不做限定。
具体地，对于终端设备采用该多个上行发射波束中的第一上行发射波束发送的U2个上行信号，网络设备可以采用U2个上行接收波束中的每个上行接收波束进行一次测量，得到该第一上行发射波束与该每个上行接收波束构成的上行波束对所对应的测量值。或者，如果该终端设备采用该第一上行发射波束发送的上行信号的个数小于U2，该网络设备可以采用相同数量的上行接收波束对该终端设备采用该第一上行发射波束发送的信号分别进行一次测量，得到由多个上行接收波束与该第一上行发射波束构成的多个上行波束对中每个上行波束对所对应的测量值。
具体地，假设网络设备的第一上行接收波束与终端设备的第一上行发射波束构成第一上行波束对，则第一上行波束对所对应的测量值可以是网络设备通过采用第一上行接收波束对终端设备采用第一上行发射波束发送的上行信号进行测量得到的。这样，通过采用多个上行接收波束对该终端设备采用该第一上行发射波束发送的上行信号进行测量，该网络设备可以得到第一 测量值集合。其中，该第一测量值集合可以包括由该第一上行发射波束与该多个上行接收波束构成的多个上行波束对中每个上行波束对所对应的测量值，该多个上行接收波束可以为该U2个上行接收波束中的部分或全部上行接收波束，本发明实施例对此不做限定。

可选地，该网络设备还可以根据第一上行发射波束构成的多个上行波束对所对应的测量值，得到该多个上行波束对中每个上行波束对的度量值，这样，该网络设备可以得到该第一上行发射波束所对应的第一度量值集合。其中，可选地，某个上行波束对的度量值可以是该上行波束对所对应的测量值的函数。例如，某个上行波束对的度量值可以等于该上行波束对所对应的测量值，或者，某个上行波束对的度量值可以等于该上行波束对的多个测量值的加权平均，该多个测量值可以是该上行波束对的不同测量量所对应的测量值，但本发明实施例不限于此。
可选地，该网络设备还可以根据该第一测量值集合，确定该第一上行发射波束所对应的度量值。这里的第一上行发射波束所对应的度量值可以是该网络设备通过采用多个上行接收波束中的每个上行接收波束测量该终端设备采用该第一上行发射波束发送的上行信号得到的，具体地，该第一上行发射波束所对应的度量值可以是根据该第一上行发射波束与该多个上行接收波束所构成的多个上行波束对中每个上行波束对的度量值得到的。可选地，该第一上行发射波束所对应的度量值可以是由该第一上行发射波束所构成的多个上行波束对中具有最大测量值的上行波束对的度量值，也就是该第一度量值集合中的最大值；或者，该第一上行发射波束所对应的度量值可以是该第一度量值集合中的至少两个度量值的数学平均值或加权平均值，但本发明实施例不限于此。

具体地，该网络设备可以根据该多个上行发射波束中每个上行发射波束所对应的测量值集合，确定该每个上行发射波束所对应的度量值，其中，确定方式可以参照上述对第一上行发射波束的描述，为了简洁，这里不再赘述。

可选地，该第一门限值可以是协议规定的，也可以是该网络设备根据当前网络状态或其它参数确定的，也可以是网络设备与终端设备协商确定的，本发明实施例对此不做限定。
可选地，该至少一个第二上行波束对可以为上述剩余的上行波束对中与该最大度量值之间的差值小于第一门限值的所有或部分上行波束对。作为一个可选实施例，该网络设备可以将该剩余的上行波束对中与该最大度量值之间的差值小于第一门限值的所有上行波束对确定为该至少一个第二上行波束对。作为另一个可选实施例，如果该剩余的上行波束对中与该最大度量值之间的差值小于第一门限值的所有上行波束对的数量大于M2-1，则该网络设备可以将该剩余的上行波束对中对应度量值最高的前M2-1个上行波束对确定为该至少一个第二上行波束对，但本发明实施例不限于此。

应理解，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
下面将结合具体例子，详细描述本发明实施例提供的无线通信方法。在以下例子中，假设终端设备具有4个波束，这4个波束既可以作为上行发射波束，又可以作为下行接收波束。网络设备具有8个波束，这8个波束既可以作为上行接收波束，又可以作为下行发射波束。
示例1
终端设备可以根据网络设备的配置，采用这4个波束发送上行信号。针对终端设备采用上行发射波束i发送的上行信号，网络设备可以采用8个上行接收波束进行接收和测量，得到8个测量值，并且可以将这8个测量值中的最优测量值按照一定的规则映射为度量值Vi，其中，该最优测量值可以对应于最优信道状态，并且该最优测量值的确定可以依赖于测量量，本发明实施例对此不做限定。
i可以依次从1取值到4，这样，网络设备可以得到与该4个上行发射波 束对应的4个度量值{Vi，i＝1,2,3,4}。该网络设备可以从{Vi}中选择两个度量值，例如数值较大的两个度量值，并向终端设备发送指示信息，该指示信息用于指示该网络设备选择的两个度量值。
假设该网络设备选择的两个度量值为V1和V4，其中，V1>V4，则可选地，该指示信息可以包括以下信息：{上行发射波束1的编号UL_Tx_Beam_1，V1}和{上行发射波束4的编号UL_Tx_Beam_4，V4}。或者，该指示信息可以包括以下信息：{UL_Tx_Beam 1，0}和{UL_Tx_Beam 4，Δ14}，其中，Δ14可以表示V4与V1之间的差值或差值的绝对值。或者，该指示信息也可以包括以下信息：{UL_Tx_Beam 1，UL_Tx_Beam 4，Δ14}，这里省略与上行发射波束1所对应的度量值，但本发明实施例不限于此。
此外，网络设备可以采用8个下行发射波束向终端设备发送下行信号。终端设备可以通过对网络设备发送的下行信号的测量，确定用于下行传输的最优波束组合为网络设备的下行发射波束n(记为DL_Tx_Beam n)和终端设备的波束m(即为DL_Rx_Beam m)。终端设备可以通过判断下列两个条件是否同时满足来判断发射/接收波束对应性是否成立：
1、DL_Rx_Beam m映射的UL_Tx_Beam m是否包括在网络设备发送的指示信息中；
2、UL_Tx_Beam m对应的度量值与该指示信息指示的最大度量值之间的差值小于第三门限值。
示例2
网络设备通过采用8个上行接收波束对终端设备采用4个上行发射波束发送的上行信号进行测量，得到上行测量结果。该网络设备可以根据该上行测量结果，从由这8个上行接收波束与4个上行发射波束构成的32个上行波束对中挑选出度量值最高的4个上行波束对，并向终端设备发送指示信息，该指示信息可以包括该4个上行波束对中每个上行波束对的信息。
例如，这4个上行波束对及其对应的度量值可以如下：
[UL_Tx_Beam_1 UL_Rx_Beam_1 V1]；
[UL_Tx_Beam_1 UL_Rx_Beam_5 V2]；
[UL_Tx_Beam_4 UL_Rx_Beam_4 V3]；
[UL_Tx_Beam_4 UL_Rx_Beam_2 V4]；
其中，V1≥V2≥V3≥V4。
终端设备可以通过对网络设备采用8个下行发射波束发送的下行信号进行测量，得到下行测量结果。该终端设备根据下行测量结果，将由DL_Tx_Beam 4和DL_Rx_Beam 4构成的下行波束对确定为目标下行波束对，例如，由DL_Tx_Beam 4和DL_Rx_Beam 4构成的下行波束对的度量值最高，则终端设备可以通过判断以下两个条件是否同时满足来判断UL_Tx_Beam_4与DL_Rx_Beam_4是否满足波束对应性：
1、网络设备向终端设备发送的指示信息中指示了[DL_Tx_Beam 4DL_Rx_Beam 4]映射到的[UL_Tx_Beam_4 UL_Rx_Beam_4]的信息；
2、[UL_Tx_Beam_4 UL_Rx_Beam_4]的度量值与该指示信息指示的最大度量值之间的差值小于某个门限。
示例3
网络设备向终端设备发送的指示信息可以包括4个上行波束对中每个上行波束对的信息。这4个上行波束对及其对应的度量值可以如下：
[UL_Tx_Beam_1 UL_Rx_Beam_1 v_1]；
[UL_Tx_Beam_2 UL_Rx_Beam_1 v_2]；
[UL_Tx_Beam_3 UL_Rx_Beam_4 v_3]；
[UL_Tx_Beam_4 UL_Rx_Beam_4 v_4]；
其中，V1≥V2≥V3≥V4。
终端设备可以通过对网络设备采用8个下行发射波束发送的下行信号进行测量，得到下行测量结果。可选地，如果[DL_Tx_Beam_1DL_Rx_Beam_1]、[DL_Tx_Beam_1 DL_Rx_Beam_2]、[DL_Tx_Beam_4DL_Rx_Beam_3]、[DL_Tx_Beam_4 DL_Rx_Beam_4]的度量值与最大度量值之间的差值均小于某个门限值，则终端设备可以确定网络设备的DL_Tx_Beam_1与UL_Rx_Beam_1以及DL_Tx_Beam_4与UL_Rx_Beam_4满足波束对应性。可选地，如果[DL_Tx_Beam_4 DL_Rx_Beam_3]、[DL_Tx_Beam_4 DL_Rx_Beam_4]的度量值与最大度量值之间的差值大于该门限值，则表明这两个下行波束对所对应的信道质量较差，则终端设备可以确定网络设备的DL_Tx_Beam_4与UL_Rx_Beam_4不满足波束对应性。
