背景技术
在长期演进(Long Term Evolution, LTE ) 系统中, 终端一般通过发送探测参考信号 ( Sounding Reference Signal, SRS ) 来探测上行信道, SRS在时域上复用在上行子帧的最 后一个符号上。 基站可以通过 SRS获得上行信道状态信息, 从而进行上行定时检测、 功率 控制、 上行频域调度和链路自适应等操作。 在 LTE系统中, 终端会以一定的周期持续发送 SRS, SRS的发送参数都是通过高层配置的, SRS的发送参数包括 SRS的循环移位( Cycle Shift, CS )信息、 带宽信息、 跳频参数信息、 周期信息和发送子帧位置信息等。
由上可见, 在 LTE系统中, 周期性发送 SRS需要占用较多的传输资源, 由于先进的 LTE ( LTE- Advanced, LTE-A, ) 系统支持多天线技术, 因此在终端的所有发送端口中, 可 能配置了多个发送 SRS的发送端口 (筒称 SRS端口) 同时向基站发送 SRS, 传输资源的 开销更大。 为了提高发送 SRS时的资源利用率, 减少发送 SRS的资源开销, 现有技术在 LTE-A系统中引入了非周期发送 SRS的方法,这种方法需要由基站动态指示终端发送 SRS , 终端只发送一次 SRS, 而不会周期性的发送, 若终端配置了多个 SRS端口, 则终端会同时 通过所有 SRS端口向基站发送 SRS。 通过上述非周期发送 SRS的方法, 基站可以灵活的 指示终端发送 SRS, 以获得所需要的上行信道状态信息, 从而减少了发送 SRS时的资源开 销。
在 LTE-A系统中, 由于终端可能同时通过多个 SRS端口发送 SRS, 因此如何实现多 个 SRS端口的资源复用是一个重要问题。 终端的多个 SRS端口在发送 SRS时, 可以占用 相同的时域资源, 而通过不同的 CS (属于码域资源)或者传输梳 ( Comb ) (属于频域资源) 进行资源复用, 但是终端如何确定各 SRS端口的 CS信息和 Comb信息, 现有技术并没有 给出具体的技术方案, 导致终端无法准确的向基站发送 SRS。

图 4为本发明实施例二中, SRS发送装置结构示意图。 具体实施方式
下面结合各个附图对本发明实施例技术方案的主要实现原理、 具体实施方式及其对应 能够达到的有益效果进行详细地阐述。
如图 1所示, 为本发明实施例中, SRS发送方法流程图, 其具体处理过程如下: 步骤 11 , 接收基站发送的 SRS配置指示信息, 所述 SRS配置指示信息中包含 CS配置指 示信息以及 Comb配置指示信息;
在 LTE-A系统中, 终端存在多个 SRS端口同时向基站发送 SRS, 此时, 多个 SRS端口占 用相同的时域资源, 通过不同的 CS信息进行码域资源复用或者通过不同的 Comb信息进行 频域资源复用。
为了指示终端对各 SRS端口的 CS信息和 Comb信息进行配置,基站可以在高层信令或者 物理下行控制信道(Physical Downlink Control Channel, PDCCH )信令中携带 SRS配置指 示信息, SRS配置指示信息中携带有 3比特的 CS配置指示信息和 1比特的 Comb配置指示信 息, 终端通过这些配置指示信息来确定各个 SRS端口的 CS信息和 Comb信息。
步骤 12, 根据所述 CS配置指示信息, 确定各 SRS端口的 CS信息, 其中 CS信息为 0~7中 的数值; 其中根据 CS配置指示信息确定各 SRS端口的 CS信息可以但不限于包含下述三种实施 方式, 分别为:
第一种实施方式, 预先设置 SRS端口数量和 CS间距的对应关系, 接收到 SRS配置指示 信息后, 终端根据 SRS配置指示信息中包含的 CS配置指示信息, 确定第一个 SRS端口的 CS 信息, 即将 SRS配置指示信息中包含的 CS配置指示信息作为第一个 SRS端口的 CS信息, 然 后根据 SRS端口的数量, 在 SRS端口数量和 CS间距的对应关系中, 查找相邻 SRS端口间的 CS间距, 再根据第一个 SRS端口的 CS信息以及相邻 SRS端口间的 CS间距, 确定其他 SRS端 口的 CS信息;
例如, 预设 SRS端口数量和 CS间距的对应关系为: 2个 SRS端口对应的 CS间距为 4 , 4 个 SRS端口对应的 CS间距为 2 , 终端接收到的 SRS配置指示信息中包含的 CS配置指示信息 为 0, 则终端将第一个 SRS端口的 CS信息确定为 0, 若 SRS端口的数量为 1个, 则该 SRS端口 的 CS信息即为 0; 若 SRS端口的数量为 2个, 则根据预设的 SRS端口数量和 CS间距的对应关 系可知, 第一个 SRS端口的 CS信息与第二个 SRS端口的 CS信息之间的间距为 4 , 因此第二 个 SRS端口的 CS信息应为 4; 若 SRS端口的数量为 4个, 则根据预设的 SRS端口数量和 CS间 距的对应关系可知, 第一个 SRS端口的 CS信息与第二个 SRS端口的 CS信息之间的间距、 第 二个 SRS端口的 CS信息与第三个 SRS端口的 CS信息之间的间距以及第三个 SRS端口的 CS 信息与第四个 SRS端口的 CS信息之间的间距均为 2 , 因此第二个 SRS端口的 CS信息应为 2 , 第三个 SRS端口的 CS信息应为 4, 第四个 SRS端口的 CS信息应为 6。
第二种实施方式, 接收到 SRS配置指示信息后, 终端根据 SRS配置指示信息中包含的 CS配置指示信息, 确定第一个 SRS端口的 CS信息, 即将 SRS配置指示信息中包含的 CS配置 指示信息作为第一个 SRS端口的 CS信息, 然后通过其他指示信息确定相邻 SRS端口间的 CS 间距, 再根据第一个 SRS端口的 CS信息以及确定出的相邻 CS间距, 确定其他 SRS端口的 CS 信息, 其中基站可以单独为终端设置 CS间距, 此时基站通过 PDCCH信令或者高层信令将 单独为终端设置的 CS间距发送给终端, 此外也可以为小区内的所有终端设置相同的 CS间 距, 此时终端可以通过所属小区的 CS间距配置信息确定相邻 SRS端口间的 CS间距;
例如, 终端接收到的 SRS配置指示信息中包含的 CS配置指示信息为 0, 则终端将第一 个 SRS端口的 CS信息确定为 0 , 终端通过其他指示信息确定出相邻的 SRS端口间的 CS间距 为 2, 且 SRS端口的数量为 2个, 则第二个 SRS端口的 CS信息应为 2。
第三种实施方式, 接收到 SRS配置指示信息后, 终端将 SRS配置指示信息中包含的 CS 配置指示信息确定为各 SRS端口的 CS索引信息,然后根据确定出的 CS索引信息,在 CS索引 信息和各发送端口的 CS信息之间的对应关系中, 查找各 SRS端口的 CS信息。
例如,预先建立 CS索引信息和各发送端口的 CS信息之间的对应关系,该对应关系可以 但不限于如表 1或表 2所示, 其中可以基于在保证嵌套结构的前提下最大化各个 SRS端口间 的 CS间距的原则, 来建立上述对应关系。 若终端接收到的 SRS配置指示信息中包含的 CS配 置指示信息为 4, 且 SRS端口的数量为 4, 建立的上述对应关系如表 1所示, 则终端通过查表 1可知, 第一个 SRS端口 (端口 0) 的 CS信息为 4, 第二个 SRS端口 (端口 1 ) 的 CS信息为 0, 第三个 SRS端口 (端口 2) 的 CS信息为 6, 第四个 SRS端口 (端口 3) 的 CS信息为 2; 若终端 建立的上述对应关系如表 2所示, 则终端通过查表 2可知, 第一个 SRS端口 (端口 0) 的 CS 信息为 4, 第二个 SRS端口 (端口 1 ) 的 CS信息为 0, 第三个 SRS端口 (端口 2) 的 CS信息为 2, , 第四个 SRS端口 (端口 3) 的 CS信息为 6。
Figure imgf000007_0001
表 2 步骤 13 , 根据所述 Comb配置指示信息, 确定各 SRS端口的 Comb信息, 其中 Comb信息 为 0或 1 ;
本发明实施例中终端可以根据接收到的 SRS配置指示信息中包含的 Comb配置指示信 息来确定各 SRS端口的 Comb信息,还可以根据接收到的 SRS配置指示信息中包含的 CS配置 指示信息和 Comb配置指示信息, 来确定各 SRS端口的 Comb信息。
终端根据接收到的 SRS配置指示信息中包含的 Comb配置指示信息, 确定各 SRS端口的 Comb信息的具体过程可以但不限于为下述:
预先设置 SRS端口 Comb配置规则,例如设置所有 SRS端口的 Comb信息均一致,或预设 若千个 SRS端口的 Comb信息与第一个 SRS端口的 Comb信息一致, 其他 SRS端口的 Comb信 息与第一个 SRS端口的 Comb信息不一致(即部分 SRS端口的 Comb信息与第一个 SRS端口的 Comb信息一致, 另一部分 SRS端口的 Comb信息与第一个 SRS端口的 Comb信息不一致), 终 端接收到 SRS配置指示信息后, 根据 SRS配置指示信息中包含的 Comb配置指示信息, 确定 第一个 SRS端口的 Comb信息, 即将 SRS配置指示信息中包含的 Comb配置指示信息,作为第 一个 SRS端口的 Comb信息, 然后根据第一个 SRS端口的 Comb信息以及预设的 SRS端口 Comb配置规则, 确定其他 SRS端口的 Comb信息。
例如, 当 SRS端口 Comb配置规则为所有 SRS端口的 Comb信息均一致时,若终端接收到 的 SRS配置指示信息中包含的 Comb配置指示信息为 0, SRS端口的数量为 2个, 则终端将第 一个 SRS端口的 Comb信息确定为 0,且第二个 SRS端口的 Comb信息也为 0; 当 SRS端口 Comb 配置规则为预设第二个 SRS端口的 Comb信息与第一个 SRS端口的 Comb信息一致, 第三个 SRS端口和第四个 SRS端口的 Comb信息与第一个 SRS端口的 Comb信息不一致时,若终端接 收到的 SRS配置指示信息中包含的 Comb配置指示信息为 0, SRS端口的数量为 4个, 则终端 将第一个 SRS端口的 Comb信息确定为 0, 第二个 SRS端口的 Comb信息为 0, 第三个 SRS端口 和第四个 SRS端口的 Comb信息为 1。
终端根据接收到的 SRS配置指示信息中包含的 Comb配置指示信息和 CS配置指示信息, 确定各 SRS端口的 Comb信息的具体过程可以但不限于为下述:
接收到 SRS配置指示信息后, 终端根据 SRS配置指示信息中包含的 Comb配置指示信 息,确定第一个 SRS端口的 Comb信息,即将 Comb配置指示信息作为第一个 SRS端口的 Comb 信息, 然后将 CS配置指示信息确定为各 SRS端口的 Comb索引信息, 根据确定出的 Comb索 引信息, 在 Comb索引信息和各发送端口的 Comb—致性信息之间的对应关系中, 查找其他 SRS端口的 Comb—致性信息, 查找到的 Comb—致性信息是表示对应 SRS端口的 Comb信息 与第一个 SRS端口的 Comb信息是否一致的信息,再根据第一个 SRS端口的 Comb信息以及确 定出的其他 SRS端口的 Comb信息与第一个 SRS端口的 Comb信息之间的一致性信息,确定其 他 SRS端口的 Comb信息。 例如, 预先建立 Comb索引信息和各发送端口的 Comb—致性信息之间的对应关系, 该 对应关系可以但不限于如表 3、 表 4或表 5所示, 需要注意的是, 在 Comb索引信息和各发送 端口的 Comb—致性信息之间的对应关系中, Comb索引信息对应的并不是各发送端口的 Comb信息, 而是各发送端口的 Comb—致性信息, 例如端口 0的 Comb—致性信息为 0, 端口 1的一致性信息为 1 , 即第一个 SRS端口与第二个 SRS端口的 Comb信息不一致。 若终端接收 到的 SRS配置指示信息中包含的 Comb配置指示信息为 0, CS配置指示信息为 4, 且 SRS端口 的数量为 4, 建立的 Comb索引信息和各发送端口的 Comb—致性信息之间的对应关系如表 3 所示, 则终端将第一个 SRS端口 (端口 0 ) 的 Comb信息确定为 0 , 通过查表 6可知, 第二个 SRS端口 (端口 1 ) 的 Comb信息与第一个 SRS端口 (端口 0 ) 的 Comb信息一致, 也为 0, 第 三个 SRS端口(端口 2 )与第四个 SRS端口(端口 3 )的 Comb信息与第一个 SRS端口(端口 0 ) 的 Comb信息不一致, 为 1。

此外, 本发明实施例还提出, 也可以将 CS索引信息和 CS信息的对应关系, 以及 Comb 索引信息和 Comb—致性信息的对应关系,合成为一个对应关系,可以但不限于如表 6、表 7、 表 8、 表 9或表 10所示, 此时将接收到的 SRS配置指示信息中包含的 CS配置指示信息确定为 索引信息, 将 Comb配置指示信息作为第一个 SRS端口的 Comb信息, 然后根据确定出的索 引信息, 在合成的上述对应关系中, 确定各 SRS端口的 CS信息以及其他 SRS端口的 Comb 一致性信息,然后才 居第一个 SRS端口的 Comb信息和其他 SRS端口的 Comb—致性信息,确 定其他 SRS端口的 Comb信息。
例如, 若终端接收到的 SRS配置指示信息中包含的 Comb配置指示信息为 0, CS配置指 示信息为 4,且 SRS端口的数量为 4,建立的索引信息和各发送 SRS端口的 CS信息以及各 SRS 端口的 Comb—致性信息之间的对应关系如表 6所示, 则终端将第一个 SRS端口 (端口 0 )的 Comb信息确定为 0, 通过查表 9可知, 第一个 SRS端口 (端口 0 )的 CS信息确定为 4, 第二个 SRS端口 (端口 1 )的 CS信息为 0, 其 Comb信息与第一个 SRS端口 (端口 0 )的 Comb信息一 致, 为 0, 第三个 SRS端口 (端口 2 )与第四个 SRS端口 (端口 3 )的 CS信息分别为 6, 2, 其 Comb信息与第一个 SRS端口 (端口 0 ) 的 Comb信息不一致, 均为 1。 CS信息 Comb一致性信息 索
