Description

探测参考信号SRS发送方法、装置及接收方法、装置 技术领域
本发明涉及通信领域，具体而言，涉及一种探测参考信号SRS发送方法、装置及接收方法、装置。
背景技术
机器类型通信(Machine Type Communication，简称为MTC)用户终端(User Equipment，简称为用户设备或终端)，又称，机器到机器(Machine to Machine，简称为M2M)用户通信设备，是目前物联网的主要应用形式。
近年来，由于长期演进(Long-Term Evolution，简称为LTE)/高级长期演进系统(Long-Term Evolution Advance，简称为LTE-Advance或LTE-A)的频谱效率高，越来越多的移动运营商选择LTE/LTE-A作为宽带无线通信系统的演进方向。基于LTE/LTE-A的MTC多种类数据业务也将更具吸引力。
MTC设备通常是低成本的设备，具有支持的射频(Radio Frequency，简称为RF)带宽比较小、单接收天线等特征，其RF发射和接收带宽一般为1.4MHz。对于系统带宽大于1.4MHz的情况，如果为MTC UE在上行频段上划分出多个上行发送的窄带，可以降低资源分配的指示开销，对于需要覆盖增强的MTC UE来说，可以减少其发送的重复次数，节省无线资源。
在LTE系统中，小区会广播一个小区专用参数叫探测参考信号(Sounding reference signal，简称为SRS)带宽，其为小区最大的SRS带宽，下述将其称为小区的SRS带宽。除了小区的SRS带宽，演进型基站(E-UTRAN NodeB，简称为eNB)还会为UE配置UE发送SRS的带宽，即UE的SRS带宽，小区内的UE在小区的SRS带宽内按照eNB配置的UE的SRS带宽发送SRS。ebb通过测量SRS，得到UE的信道状况。在调度UE传输时，可以根据得到的UE的信道状况，将UE调度到合适的频域位置进行数据传输，以获得调度增益。eNB为UE配置的SRS带宽是4个PRB的整数倍，对于MTC UE来说，每次传输最多只能支持4个PRB的SRS带宽。MTC UE工作的频段通常只是整个系统带宽的一部分，如果MTC UE完全沿用相关的周期SRS的发送方式，即以4个PRB的SRS带宽在小区的SRS带宽上跳频发送，在没有分配给MTC UE的频域位置也发送SRS，对UE来说做了很多的“无用功”，不利于UE节能。
针对相关技术中，终端发送SRS效率较低的问题，还未提出有效的解决方案。

需要说明的是，上述各个模块是可以通过软件或硬件来实现的，对于后者，可以通过以 下方式实现，但不限于此：上述各个模块均位于同一处理器中；或者，上述各个模块分别位于第一处理器、第二处理器和第三处理器…中。
针对相关技术中存在的上述问题，下面结合可选实施例进行说明，本可选实施例结合了上述可选实施例及其可选实施方式。
实施例一：
一种SRS的发送方法，包括在第一带宽(相当于上述指定带宽)上发送SRS。第一带宽是由一个或者多个不连续的PRB簇组成的虚拟的连续带宽。PRB簇由系统带宽中的多个连续的PRB组成。多个不连续的PRB簇包含的PRB个数可以相同也可以不同。
图9是根据本发明实施例的第一带宽示意图，如图9所示，系统带宽中斜线表示的两个PRB簇被虚拟成一个连续的第一带宽，UE将在第一带宽内按照某一种图样周期发送SRS。
为了能够采用4个PRB的SRS带宽发送SRS，第一带宽以及PRB簇包含的PRB数目都应该是4的整数倍。
第一带宽可以是eNB指示的，如通过公共消息指示的，比如eNB通过SIB消息通知某一类UE，如窄带UE，其第一带宽位置或者其包含的PRB，比如用bitmap表示。或者是通过UE专有消息指示的，即eNB为UE指示UE的第一带宽的位置，可以通过RRC信令通知或者通过物理层信令通知。可选地，UE可以被分为很多组，一个组内的UE对应的第一带宽也相同，组内的UE在其对应的第一带宽上发送SRS；不同组的UE的第一带宽不同。可选地，组对应的第一带宽之间没有重叠。
第一带宽也可以是预设的，比如对于每一种系统带宽都会对应一个第一带宽，又比如在频分双工(Frequency Division Duplexing，简称为FDD)：系统，下行带宽和上行带宽之间存在一种对应关系，第一带宽可以根据分配给窄带UE的下行工作窄带确定，或者根据最近的一个或者多个上行工作窄带确定。或者第一带宽预设为用于传输物理上行共享信道(Physical Uplink Shared Channe，简称为PUSCH)和/或物理上行链路控制信道(Physical Uplink Control Channel，简称为PUCCH)和/或物理随机接入信道(Physical Random Access Channel，简称为PRACH)的频域资源。当用于传输PUSCH和/或PUCCH和/或PRACH的频域资源包含的PRB不是4的整数倍时，第一带宽是该频域资源经过扩展或者缩小后得到的包含4的整数倍个PRB的频域资源。扩展或者缩小的方式可以是预定义的或者是通知的。这样，在第一带宽内包含4的整数倍个PRB，使得UE能在第一带宽内按照4个PRB的SRS进行发送。该用于传输PUSCH和/或PUCCH和/或PRACH的频域资源是预设的或者是eNB指示的。
可选地，如果PUSCH和PUCCH和PRACH分别对应不同的窄带资源，那么第一带宽是预设的或者eNB指示的用于传输PUSCH的频域资源。当用于传输PUSCH的频域资源包含的PRB不是4的整数倍时，第一带宽是该频域资源经过扩展或者缩小后得到的包含4的整数倍个PRB的频域资源。或者如果PUSCH和PUCCH可能混合在多个窄带内发送，那么第一带宽是预设的或者eNB指示的用于传输PUSCH或者混合传输PUSCH和PUCCH的频域资源。当 用于传输PUSCH或者混合传输PUSCH和PUCCH的频域资源包含的PRB不是4的整数倍时，第一带宽是该频域资源经过扩展或者缩小后得到的包含4的整数倍个PRB的频域资源。
图10是根据本发明实施例的频域资源扩展后得到的第一带宽的示意图，如图10所示，给出了一个扩展的例子，用于窄带UE工作的频域资源由5个窄带组成，该5个窄带是eNB通知的用于UE发送PUSCH的频域资源。每个窄带包含6个PRB，其中两个窄带是连续的，其他三个窄带是连续的，形成了两个PRB簇，分别为12个PRB和18个PRB，其中18个PRB不是4个PRB的整数倍，通过将邻近的2个PRB也扩展进来，形成20个PRB，变成4的倍数，然后这12个PRB和20个PRB组成虚拟的包含32个PRB的第一带宽，UE在第一带宽内采用4个PRB的SRS带宽进行发送。
图11是根据本发明实施例的频域资源缩小后得到的第一带宽的示意图，如图11所示，给出了一个缩小的例子，用于窄带UE工作的频段由5个窄带组成，每个窄带包含6个PRB，其中两个窄带是连续的，其他三个窄带是连续的，形成了两部分工作频段，分别为12个PRB和18个PRB，其中18个PRB不是4个PRB的整数倍，通过将18个PRB组成的PRB簇中频率最低的2个PRB去掉，即将格子部分去掉，形成16个PRB，变成4的倍数，然后这12个PRB和16个PRB组成虚拟的包含28个PRB的第一带宽，UE在第一带宽内采用4个PRB的SRS带宽进行发送。
UE将工作频段虚拟成第一带宽后，就可以将第一带宽当作SRS的频域发送范围。eNB还会通知UE其频域的起始位置、占用的梳齿、发送周期以及offset、采用的序列的循环偏移，UE根据eNB通知的这些信息，在第一带宽内根据相关的跳频图样进行SRS的发送。进一步地，eNB通知UE的频域的起始位置，可以只在第一带宽内指示，比如假设第一带宽内有32个PRB，一共容纳8个4个PRB的SRS带宽，可以采用3bit来指示起始位置是哪个4个PRB的SRS带宽。
图12是根据本发明实施例的在第一带宽内UE的SRS带宽为4时的SRS发送示意图，如图12所示，给出了一个在发送SRS的子帧上按照一种预设的规则跳频发送SRS，遍历整个第一带宽，其中发送SRS的符号由黑色部分表示。该预设的规则或者跳频公式与第一带宽有关。实际应用中不限于这种发送方式。
eNB按照同样的规则接收SRS，获得UE的信道状况，调度UE发送上行信号。
另外，eNB也可以为窄带UE配置相关的SRS，即跳频的频域范围是eNB配置的小区的SRS带宽。优选地，eNB可以将该相关的SRS的周期配置的较大，比本发明中的跳频周期大，这样，eNB不仅可以在UE的工作频带上快速接收SRS，得到UE的信道状况，进而调度该UE发送PUSCH，也可以获得其他频带上UE的信道状况，作为将来调整UE工作频带的依据。当相关的SRS和本发明中的第一带宽上的SRS发生冲突在同一子帧出现时，可以定义一个优先级，比如优先发送相关的SRS，或者优先发送第一带宽上的SRS。
该第一带宽也可以是变化的。比如eNB将PRB#0～17分配给UE#1作为其发送SRS的频段，首先UE将其虚拟为第一带宽，然后在第一带宽上发送SRS，一段时间后，eNB还可以通 知UE其发送SRS的频段发生了变化，变为PRB#23～29，UE收到变更信息之后，将其虚拟为第一带宽，然后在第一带宽上发送SRS。
为了不对相关的LTE UE的SRS造成干扰以及避免相关的LTE UE对窄带UE的干扰，eNB在配置参数时，应将这两种UE占用的资源分开。eNB可以给这两种UE配置不同的序列的循环偏移，比如8种循环偏移中，其中4个配置给相关的LTE UE使用，其他几种分配给窄带UE使用；或者给这两种UE配置不同的梳齿，比如给相关的LTE UE分配偶数子载波对应的梳齿，给窄带UE分配奇数子载波对应的梳齿；或者给这两种UE配置不同的发送子帧，保证其不会在同一个子帧中出现；或者给这两种UE配置不同的发送SRS的频域范围，相关的LTE UE发送SRS的频域范围是小区的SRS带宽，一般占用整个系统带宽中心的若干个PRB，可以将窄带UE发送SRS的频域范围配置在小区的SRS带宽之外；或者也可将上述任意两个或者多个进行联合来隔离这两种UE占用的资源。这样，虽然两种UE采用了不同的SRS跳频机制，但是不会发生干扰。
实施例二：
与实施例一类似，将第一带宽作为SRS的频域发送范围，在该第一带宽上发送SRS。不同的是，采用一种6个PRB的SRS带宽发送方式，即UE在SRS发送子帧上发送的SRS在频域上占用6个PRB。该跳频公式由第一带宽确定。该第一带宽包含的PRB的个数为6的整数倍。UE根据eNB的配置，根据预设的跳频图样在第一带宽内发送SRS。eNB可以通知UE其频域的起始位置、占用的梳齿、发送周期以及offset、采用的序列的循环偏移，跳频方式是预定义的或者是通知的。这样，对于RF发送带宽只有1.4MHz的UE来说，可以在其工作的6个PRB上发一个占满整个工作窄带的SRS，提高了SRS的发送效率。
图13是根据本发明实施例的在第一带宽内UE的SRS带宽为6时的SRS发送示意图，如图13所示，给出了一个UE在发送SRS的子帧上按照一种预设的规则跳频发送SRS的例子，遍历整个第一带宽，其中发送SRS的符号由黑色部分表示。实际应用中不限于这种发送方式。
与实施例一类似，当用于传输PUSCH和/或PUCCH和/或PRACH的频域资源包含的PRB不是6的整数倍时，第一带宽是该频域资源经过扩展或者缩小后得到的包含6的整数倍个PRB的频域资源。
可选地，当第一带宽包含的PRB个数为4和6的公倍数时，在第一带宽内，按照4个PRB的SRS带宽或者6个PRB的SRS带宽进行发送，具体按照哪个SRS带宽发送可以是eNB通知的，也可以是预设的。
可选地，如果PUSCH和PUCCH和PRACH分别对应不同的窄带资源，那么第一带宽是预设的或者eNB指示的用于传输PUSCH的频域资源，或者是该频域资源经过扩展或者缩小后得到的包含6的整数倍个PRB的频域资源。或者如果PUSCH和PUCCH可能混合在多个窄带内发送，那么第一带宽是预设的或者eNB指示的用于传输PUSCH或者混合传输PUSCH和PUCCH的频域资源，或者是该频域资源经过扩展或者缩小后得到的包含6的整数倍个PRB的频域资源。
eNB按照同样的规则接收SRS，获得UE的信道状况，调度UE在该第一带宽内或者该一个或者多个工作频段内发送上行信号。
为了不对相关的LTE UE的SRS造成干扰以及避免相关的LTE UE对窄带UE的干扰，eNB在配置参数时，应将这两种UE占用的资源分开。eNB可以给这两种UE配置不同的梳齿，比如给相关的LTE UE分配偶数子载波对应的梳齿，给窄带UE分配奇数子载波对应的梳齿；或者给这两种UE配置不同的发送子帧，保证其不会在同一个子帧中出现；或者给这两种UE配置不同的发送SRS的频域范围，相关的LTE UE发送SRS的频域范围是小区的SRS带宽，一般占用整个系统带宽中心的若干个PRB，可以将窄带UE发送SRS的频域范围配置在小区的SRS带宽之外；或者也可将上述任意两个或者多个进行联合来隔离这两种UE占用的资源。这样，虽然两种UE采用了不同的SRS跳频机制，但是不会发生干扰。
综上所述，本发明提出了的一种SRS的发送方法，使MTC UE或者窄带UE高效地发送SRS，eNB快速得到MTC UE或者窄带UE的上行信道状况，获得调度增益。

在另外一个实施例中，还提供了一种存储介质，该存储介质中存储有上述软件，该存储介质包括但不限于：光盘、软盘、硬盘、可擦写存储器等。
