具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”及“若”可以被解释成为“在……时”或“当……时” 或“响应于确定”。
应当理解，尽管在本公开实施例为了便于理解而编号的方式对步骤进行了说明，但是这些编号并不代表步骤的执行顺序，也并不代表采用顺序编号的步骤必须在一起执行。应当理解，采用顺序编号的多个步骤中的一个或几个步骤可以单独执行以解决相应的技术问题并达到预定的技术方案。即使是在附图中被示例性的列在一起的多个步骤，并不代表这些步骤必须被一起执行；附图只是为了便于理解而示例性的将这些步骤列在了一起。
图1示出的是本公开一个示意性实施例提供的通信系统的框图，如图1所示，该通信系统可以包括：网络侧12和终端13。
网络侧12中包括若干网络侧设备120。网络侧设备120可以是基站，基站是一种部署在接入网中用以为终端提供无线通信功能的装置。该基站既可以是终端13的服务小区的基站，也可以是终端13的服务小区相邻小区的基站。基站可以包括各种形式的宏基站，微基站，中继站，接入点、发送接收点(Transmission Reception Point，TRP)等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，在5G新空口(NR，New Radio)系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能描述，会变化。网络侧设备120也可以是定位管理功能实体(Location Management Function，LMF)。
终端13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile Station，MS)，终端，物联网设备(Internet of Things,IoT),工业物联网设备(Industry Internet of Things,IIoT)等等。为方便描述，上面提到的设备统称为终端。网络侧设备120与终端13之间通过某种空口技术互相通信，例如Uu接口。
当定位用途参考信号在终端的非激活带宽部分(BandWidth Part，BWP)上传输，或者是在与当前使用的激活BWP子载波间隔(SubCarrier Spacing，SCS)不同的激活BWP上传输时，需要为终端配置测量间隔(measurement gap)，以使终端能在该测量间隔中传输并测量定位参考信号。
相关技术中，测量间隔都是基于终端配置的，也即终端在接收到测量间隔后，所有的天线端口都会断开在原本的激活带宽部分上的传输，部分预配置的 天线端口进行定位用途参考信号的传输和测量，另一部分天线端口既不进行定位用途参考信号传输，也不进行其他信号传输。
本公开实施例描述的通信系统以及业务场景是为了更加清楚地说明本公开实施例的技术方案，并不构成对本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着通信系统的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
图2是根据一示例性实施例示出的一种通信方法的流程图。参见图2，该方法包括以下步骤：
在步骤101中，终端确定终端中的第一天线端口和第二天线端口，所述第一天线端口和第二天线端口为不同的天线端口。
在步骤101中，天线端口可以是指终端中逻辑的天线端口(Antenna Port)。
在步骤102中，终端采用所述第一天线端口与第一网络侧设备进行定位用途参考信号传输，同时，终端采用所述第二天线端口与第二网络侧设备进行上下行数据传输。
也即，终端在传输所述定位用途参考信号时，采用所述第二天线端口与第二网络侧设备进行上下行数据传输。
这里，定位用途参考信号可以为前述PRS或SRS。例如终端通过第一天线端口向第一网络侧设备发送SRS，或者终端通过第一天线端口接收第一网络侧设备发送的PRS。
在终端采用所述第一天线端口与第一网络侧设备传输定位用途参考信号的同时，终端采用所述第二天线端口与第二网络侧设备进行上下行数据传输。即终端在测量间隔内传输定位用途参考信号时，没有中断上下行数据传输。
在本公开实施例中，第一网络侧设备和第二网络侧设备，既可以是同一个设备，也可以是不同的设备。
在本公开实施例中，通过先确定出第一天线端口和第二天线端口，然后再采用第一天线端口进行定位用途参考信号传输，同时采用第二天线端口进行上下行数据传输。这样，在传输定位用途参考信号以进行终端定位的过程中，仍然可以采用第二天线端口进行其他数据的传输，无需中断这些数据的传输，提高了吞吐量。
可选地，确定终端中的第一天线端口和第二天线端口，包括：
基于配置信息、协议定义或本地存储，确定出所述终端中的第一天线端口；
将终端中除第一天线端口外的其他天线端口，作为第二天线端口。
这里，配置信息可以是由网络侧设备发送给终端的，这里的网络侧设备包括但不限于定位管理功能实体、以及终端的服务小区中的网络侧设备。
可选地，所述配置信息包括所述第一天线端口的索引，或者，所述配置信息包括通过所述第一天线端口传输过的参考信号或参考信号集合索引。
其中，天线端口的索引(Index)与天线端口对应，在终端和网络侧设备中同时存储有各个天线端口的索引，此时，只需要在配置信息中携带索引即可指示天线端口。
另外，可以通过第一天线端口传输过的参考信号来对第一天线端口进行标识，例如，第一天线端口传输过SRS1，则在配置信息中携带SRS1的索引，即可指示终端哪个是第一天线端口。或者，第一天线端口传输过SRS1、SRS2，此时在配置信息中携带包含SRS1、SRS2的集合的索引，从而指示终端哪个是第一天线端口。这种情况中，各种参考信号集合的索引都是终端和网络侧设备共知的。
其中，“所述配置信息包括通过所述第一天线端口传输过的参考信号或参考信号集合索引”中的参考信号包括但不限于同步信号块(Synchronization Signal Block，SSB)、信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)、PRS、SRS等。
通过上述几种方式，指示第一天线端口的方式简单，传输所需的资源少。
可选地，采用所述第一天线端口与第一网络侧设备进行定位用途参考信号传输，包括：
在测量间隔内，采用所述第一天线端口与所述第一网络侧设备进行所述定位用途参考信号传输。
可选地，该方法还包括：
确定所述测量间隔。
由于终端传输定位用途参考信号需要在测量间隔进行，因此，终端需要先确定出测量间隔的位置。
可选地，确定所述测量间隔，包括：
接收测量间隔配置信息和/或所述定位用途参考信号的时域资源位置；
基于所述测量间隔配置信息和/或所述定位用途参考信号的时域资源位置， 确定所述测量间隔。
其中，所述测量间隔配置信息用于指示每个周期内测量间隔所在的位置。例如，定位用途参考信号的传输是周期性进行地，传输周期为40、80、160毫秒等，测量间隔配置信息可以用于指示在每个周期中哪几个毫秒是用来传输定位用途参考信号的，比如每个周期的开始6毫秒用来传输定位用途参考信号。那么终端在每个周期的这6毫秒中，第一天线端口不能用于进行其它数据传输，只能用于进行定位用途参考信号的传输。
其中，所述定位用途参考信号的时域资源位置用于指示传输所述定位用途参考信号所使用的时间单元。指示定位用途参考信号时域位置的参数包括以下一种或多种的组合：时域周期，起始时隙位置，起始符号位置，占用了几个符号，一个周期内的资源重复次数，每两次重复之间的时间间隔。例如，指示在第几个时隙(slot)的第几个符号(symbol)传输定位用途参考信号，这里的时隙、符号即为前述时间单元。用来发送定位用途参考信号的时间，也就是前面的测量间隔。那么终端只需要在实际传输定位用途参考信号的符号中，使用第一天线端口进行定位用途参考信号的传输，而比如在定位用途参考信号传输的符号所在时隙的其它符号中，则终端可以使用第一天线端口进行其它数据传输。所以相对测量配置信息指示的测量间隔来说，以定位用途参考信号的时域资源位置指示来进行定位用途参考信号的传输，能在不影响定位用途参考信号传输的情况下更有利于其它数据传输。
这里，网络侧设备既可以只通知终端测量间隔在每个周期中的位置，也可以只通知终端测量间隔具体在哪个符号，也可以同时将上述两者一起通知给终端。
这里，测量间隔配置信息和/或所述定位用途参考信号的时域资源位置，可以与前述配置信息一起发送。比如，采用相同的信令或者消息，承载测量间隔配置信息和定位用途参考信号的时域资源位置中的至少一个和该配置信息。
可选地，接收测量间隔配置信息和/或所述定位用途参考信号的时域资源位置，包括：
接收系统消息、无线资源控制(Radio Resource Control，RRC)消息和LTE定位协议(LTE Positioning Protocol，LPP)消息中的至少一个，所述系统消息、RRC消息或者LPP消息携带有所述测量间隔配置信息和/或所述定位用途参考信号的时域资源位置。
这里的系统消息可以是指系统信息块(System Information Block，SIB)，SIB通常由基站广播的。
可选地，所述终端中第一天线端口的数量大于1，不同的所述第一天线端口对应的测量间隔相同或不同。
由于对终端进行定位通常需要多个网络侧设备同时进行，所以通常终端中第一天线端口的数量也大于1，这样才能和几个不同的网络侧设备进行定位用途参考信号的传输。在有多个第一天线端口时，多个第一天线端口的测量间隔可以相同，也可以不同。
可选地，采用所述第二天线端口与所述第二网络侧设备进行上下行数据传输，包括：
采用所述第二天线端口接收所述第二网络侧设备发送的同步信号块、物理下行控制信道(Physical Downlink Control Channel，PDCCH)、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)、非零功率信道状态信息参考信号(Non-Zero Power Channel State Information-Reference Signal，NZP CSI-RS)和/或定位参考信号；
或者，采用所述第二天线端口与所述第二网络侧设备进行上下行数据传输，包括：
采用所述第二天线端口向所述第二网络侧设备发送物理上行控制信道(Physical Uplink Control Channel，PUCCH)、物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、物理随机接入信道(Physical Random Access Channel，PRACH)和/或探测参考信号。
例如，在进行下行传输时，终端可以采用第二天线端口传输PDCCH、PDSCH、NZP CSI-RS、定位参考信号中的一个，也可以同时传输PDCCH、PDSCH、NZP CSI-RS、定位参考信号中的两个或以上。比如，终端中可以同时存在两个及以上第二天线端口，此时，可以分别用来传输上述信号中的两个或以上，当然也可以多个第二天线端口传输相同类型的信号，这些本公开都不做限制。上行传输的情况和下行传输情况类似，这里不做赘述。
可选地，所述第一天线端口使用的带宽部分的子载波间隔与所述第二天线端口使用的带宽部分的子载波间隔不同。
值得说明的是，前述步骤101～步骤102与上述可选步骤可以任意组合。
图3是根据一示例性实施例示出的一种通信方法的流程图。参见图3，该方法包括以下步骤：
在步骤201中，网络侧设备发送配置信息。
示例性地，配置信息用于指示终端中的第一天线端口和第二天线端口。所述第一天线端口和第二天线端口为不同的天线端口，所述终端被配置为采用所述第一天线端口与第一网络侧设备进行定位用途参考信号传输，并在传输所述定位用途参考信号时，采用所述第二天线端口与第二网络侧设备进行上下行数据传输。
在本公开实施例中，通过网络侧设备将配置信息发送给终端，使得终端可以确定出第一天线端口和第二天线端口，然后再采用第一天线端口进行定位用途参考信号传输，同时采用第二天线端口进行上下行数据传输。这样，在传输定位用途参考信号以进行终端定位的过程中，仍然可以采用第二天线端口进行其他数据的传输，无需中断这些数据的传输，提高了吞吐量。
可选地，所述配置信息包括所述第一天线端口的索引，或者，所述配置信息包括通过所述第一天线端口传输过的参考信号或参考信号集合索引。
可选地，该方法还包括：

值得说明的是，前述步骤201与上述可选步骤可以任意组合。
图4是根据一示例性实施例示出的一种通信方法的流程图。参见图4，该方法包括以下步骤：
在步骤301中，网络侧设备发送配置信息。终端接收配置信息。
在该步骤中，网络侧设备可以先确定配置信息，也即确定终端的第一天线端口，网络侧设备确定第一天线端口的方式，可以按照预定规则、或者基于终端的天线端口的信息来执行，本申请对此不做限制。
示例性地，所述配置信息包括所述第一天线端口的索引，或者，所述配置信息包括通过所述第一天线端口传输过的参考信号或参考信号集合索引。
其中，天线端口的索引(Index)与天线端口对应，在终端和网络侧设备中同时存储有各个天线端口的索引，此时，只需要在配置信息中携带索引即可指示天线端口。
另外，可以通过第一天线端口传输过的参考信号来对第一天线端口进行标识，例如，第一天线端口传输过SRS1，则在配置信息中携带SRS1的索引，即可指示终端哪个是第一天线端口。或者，第一天线端口传输过SRS1、SRS2，此时在配置信息中携带包含SRS1、SRS2的集合的索引，从而指示终端哪个是第一天线端口。这种情况中，各种参考信号索引或参考信号集合的索引都是终端和网络侧设备共知的。
其中，参考信号包括但不限于SSB、CSI-RS、PRS、SRS等。
通过上述几种方式，指示第一天线端口的方式简单，传输所需的资源少。
在本公开实施例中，配置信息可以通过系统消息、RRC消息、LPP消息中的至少一个进行传输。
在步骤302中，终端基于配置信息确定出所述终端中的第一天线端口。
当配置信息包括的是第一天线端口的索引时，终端只需要基于该第一天线端口的索引确定出对应的第一天线端口即可。当配置信息包括的是参考信号或参考信号集合索引，终端可以基于各个天线端口历史传输情况，确定出对应的天线端口。这种情况下，终端需要存储有各个天线端口传输参考信号的情况，该情况可以是每个端口传输的参考信号、或者参考信号集合索引。
在本公开实施例中，终端是基于网络侧设备发送的配置信息确定出的第一天线端口。在其他实施例中，终端也可以基于协议定义或本地存储，确定出所述终端中的第一天线端口。
在步骤303中，终端将所述终端中除所述第一天线端口外的其他天线端口，作为所述第二天线端口。
在步骤304中，终端确定所述测量间隔。
在本公开实施例中，步骤304可以包括：
接收测量间隔配置信息和/或所述定位用途参考信号的时域资源位置，所述测量间隔配置信息用于指示每个周期内测量间隔所在的位置，所述定位用途参考信号的时域资源位置用于指示传输所述定位用途参考信号所使用的时间单元；基于所述测量间隔配置信息和/或所述定位用途参考信号的时域资源位置，确定所述测量间隔。
其中，所述测量间隔配置信息用于指示每个周期内测量间隔所在的位置。例如，定位用途参考信号的传输是周期性进行地，传输周期为40、80、160毫秒等，测量间隔配置信息可以用于指示在每个周期中哪几个毫秒是用来传输定位用途参考信号的，比如每个周期的开始6毫秒用来传输定位用途参考信号。那么终端在每个周期的这6毫秒中，第一天线端口不能用于进行其它数据传输，只能用于进行定位用途参考信号的传输。
其中，所述定位用途参考信号的时域资源位置用于指示传输所述定位用途参考信号所使用的时间单元。指示定位用途参考信号时域位置的参数包括以下一种或多种的组合：时域周期，起始时隙位置，起始符号位置，占用了几个符号，一个周期内的资源重复次数，每两次重复之间的时间间隔。例如，指示在第几个时隙(slot)的第几个符号(symbol)传输定位用途参考信号，这里的时隙、符号即为前述时间单元。用来发送定位用途参考信号的时间，也就是前面的测量间隔。那么终端只需要在实际传输定位用途参考信号的符号中，使用第 一天线端口进行定位用途参考信号的传输，而比如在定位用途参考信号传输的符号所在时隙的其它符号中，则终端可以使用第一天线端口进行其它数据传输。所以相对测量配置信息指示的测量间隔来说，以定位用途参考信号的时域资源位置指示来进行定位用途参考信号的传输，能在不影响定位用途参考信号传输的情况下更有利于其它上下行数据传输。
这里，网络侧设备既可以只通知终端测量间隔在每个周期中的位置，也可以只通知终端测量间隔具体在哪个符号，也可以同时将上述两者一起通知给终端。
这里，测量间隔配置信息和/或所述定位用途参考信号的时域资源位置，可以与前述配置信息一起发送。比如，采用相同的信令或者消息，承载测量间隔配置信息和定位用途参考信号的时域资源位置中的至少一个和该配置信息。
示例性地，接收测量间隔配置信息和/或所述定位用途参考信号的时域资源位置，包括：
接收系统消息、RRC消息和LPP协议消息中的至少一个，所述系统消息、RRC消息或者LPP消息携带有所述测量间隔配置信息和/或所述定位用途参考信号的时域资源位置。
这里的系统消息可以是指SIB，SIB通常由基站广播的。
在步骤305中，在测量间隔内，终端采用所述第一天线端口与所述第一网络侧设备进行所述定位用途参考信号传输，同时，采用所述第二天线端口与第二网络侧设备进行上下行数据传输。
示例性地，所述终端中第一天线端口的数量大于1，不同的所述第一天线端口对应的测量间隔相同或不同。
在步骤302中可能确定出多个第二天线端口，在步骤305中可以采用这多个天线端口中的部分或者全部天线端口进行上下行数据的传输，各个第二天线端口可以和相同或不同的网络侧设备进行通信。
在本公开实施例中，步骤305可以包括：
采用所述第二天线端口接收所述第二网络侧设备发送的同步信号块、物理下行控制信道、物理下行共享信道、非零功率信道状态信息参考信号和/或定位参考信号；
或者，采用所述第二天线端口向所述第二网络侧设备发送物理上行控制信道、物理上行共享信道、物理随机接入信道和/或探测参考信号。
第二天线端口可以和第二网络侧设备进行定位参考信号和探测参考信号的传输，其中定位参考信号和探测参考信号除了用于定位外，还可以用作其他用途。
示例性地，所述第一天线端口使用的带宽部分的子载波间隔与所述第二天线端口使用的带宽部分的子载波间隔不同。例如，第一天线端口和第二天线端口都使用激活的带宽部分进行信号传输时，二者的子载波间隔不同，如第二天线端口使用原本的子载波间隔，而该子载波间隔与第一天线端口用来传输定位用途参考信号的子载波间隔不同。当然，第一天线端口还可以使用非激活的带宽部分进行信号传输。
在本公开实施例中，第一网络侧设备和第二网络侧设备，既可以是同一个设备，也可以是不同的设备。当第一网络侧设备和第二网络侧设备为不同设备时，二者既可以是相同小区内的网络设备，例如同一个服务小区内的不同发送接收点(TRP)对应的设备、或者同一个服务小区内不同天线面板对应的设备；也可以是不同小区内的网络侧设备。
第一网络侧设备和步骤301中的网络侧设备既可以同一个设备，也可以是不同的设备。
示例性地，步骤301的网络侧设备可以为定位管理功能实体(通过LPP消息发送配置信息)，或者终端的服务小区内的网络侧设备(如基站，通过系统消息或者RRC消息发送配置信息)。
示例性地，第一网络侧设备可以为终端的服务小区内的网络侧设备，或者终端的服务小区的相邻小区内的网络侧设备。
示例性地，第二网络侧设备可以为终端的服务小区内的网络侧设备，或者终端的服务小区的相邻小区内的网络侧设备。
