Description

上行参考信号发送方法、装置、基站及用户设备
本申请要求于2016年11月03日提交中国专利局、申请号为201610954272.4、申请名称为“上行参考信号发送方法、装置、基站及用户设备”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
本申请涉及通信技术领域，尤其涉及一种上行参考信号发送方法、装置、基站及用户设备。
背景技术
频谱是无线通信中必不可少的资源。现代通信系统，例如全球移动通信系统(Global System for Mobile Communication，简称GSM)、码分多址(Code Division Multiple Access，简称CDMA)2000、宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)系统以及长期演进(Long Term Evolution，简称LTE)系统等，通常都工作在3千兆赫兹(Giga hertz，简称GHz)以下的载频上。
随着智能终端特别是视频业务的出现，当前的频谱资源已经难以满足用户对容量需求的爆炸式增长。具有更大的可用带宽的高频段特别是毫米波频段，日益成为下一代通信系统的候选频段。然而，高频段将导致更大的路径损耗，特别是大气、植被等因素的影响更进一步加剧了无线传播的损耗。
针对用户设备(User Equipment，简称UE)的上行参考信号发送来讲，波束赋形技术是降低路径损耗的一种有效方法，然而现有技术中基站为不同的赋形波束配置相同的上行参考信号资源信息，通常不同的赋形波束具有不同的波束增益，显然，基站为不同增益的赋形波束配置相同的上行参考信号资源信息，将会导致上行参考信号发送效率较低的问题。
发明内容
本申请提供一种上行参考信号发送方法、装置、基站及用户设备，基站通过为UE针对不同的赋形波束增益配置不同的上行参考信号资源信息，以提高上行参考信号发送效率。
第一方面，本申请提供一种上行参考信号发送方法，包括：
基站为用户设备UE配置M个上行参考信号资源信息，所述M为大于或者等于2的正整数；
基站将M个上行参考信号资源信息发送给UE，以使UE根据不同的赋形波束增益采用不同的上行参考信号资源信息发送上行参考信号。
一方面通过波束赋形技术补偿了路径损耗，另一方面，由于基站为用户设备UE配置 M个上行参考信号资源信息，以使UE根据不同的赋形波束增益采用不同的较匹配的上行参考信号资源信息发送上行参考信号，从而提高上行参考信号的发送效率。
可选地，基站将M个上行参考信号资源信息发送给所述UE，包括：基站通过高层信令或者物理层信令将M个上行参考信号资源信息发送给所述UE。从而提高方式上行参考信号资源信息的灵活性。
可选地，还包括：每个所述上行参考信号资源信息对应唯一的索引信息；
基站通过物理层信令发送索引信息，通过物理层信令发送的索引信息用于指示所述基站当前触发的上行参考信号发送采用的上行参考信号资源信息对应的索引信息，以使所述UE根据所述索引信息采用对应的上行参考信号资源信息发送上行参考信号。
可选地，上行参考信号资源信息用于所述UE周期或者非周期地发送上行参考信号；其中，用于周期上行参考信号发送的上行参考信号资源信息与用于非周期上行参考信号发送的上行参考信号资源信息不同。
可选地，还包括：基站向UE发送指示信息，指示信息携带在物理层信令中，用于指示所述上行参考信号发送的开始和/或所述上行参考信号发送的结束。
可选地，上行参考信号资源信息包括以下至少一项：上行参考信号梳齿配置信息、上行参考信号传输带宽配置信息、上行参考信号跳频配置信息、上行参考信号起始频域位置信息、上行参考信号子帧配置信息和上行参考信号符号配置信息。
可选地，上行参考信号符号配置信息指示用于UE发送上行参考信号的小区特定的第一正交频分复用OFDM符号的集合，和用于所述UE发送上行参考信号的UE特定的第二OFDM符号的集合；其中，所述第一OFDM符号的集合包括所述第二OFDM符号的集合。
也就是说，由于不同UE发送上行参考信号时的传输带宽可能不同，假定每个OFDM符号内每个UE只能在一个窄带上发送上行参考信号，则不同UE遍历整个系统带宽所占用的OFDM符号个数也不同。因此，基站可根据UE的不同需求进行灵活配置，即基站为UE配置用于发送上行参考信号的小区特定的第一正交频分复用OFDM符号的集合，并为UE配置用于发送上行参考信号的UE特定的第二OFDM符号的集合。

具体实施方式
波束赋形是一种基于天线阵列的信号预处理技术，波束赋形通过调整天线阵列中每个阵元的加权系数产生具有指向性的波束，从而能够获得明显的阵列增益。因此，波束赋形 技术在扩大覆盖范围、改善边缘吞吐量以及干扰抑止等方面都有很大的优势。本申请基于波束赋形技术的基础，为不同的赋形波束增益配置不同的上行参考信号资源信息，从而提高上行参考信号发送效率。
图1为本申请一实施例提供的一种上行参考信号发送方法的示意图，如图1所示，该方法包括如下流程：
步骤S101：基站为UE配置M个上行参考信号资源信息，M为大于或者等于2的正整数；
步骤S102：基站将M个上行参考信号资源信息发送给UE，以使UE根据不同的赋形波束增益采用不同的上行参考信号资源信息发送上行参考信号。
本实施例中，可选地，M为赋形波束的个数或者收发波束的对数，也就是说，基站针对每个赋形波束上的上行参考信号发送，根据波束增益的不同配置不同的上行参考信号资源信息。M个上行参考信号资源信息指的是M套上行参考信号资源信息，每套上行参考信号资源信息包括用于R(R>＝1)次上行参考信号传输所需的上行参考信号资源信息。具体地，该上行参考信号资源信息是指基站为UE配置的用于上行参考信号发送所需的资源信息，每套上行参考信号资源信息包括以下至少一项：梳齿配置信息、传输带宽配置信息、跳频配置信息、起始频域位置信息和子帧配置信息，符号配置信息。
梳齿配置信息用于指示UE发送上行参考信号时可与其他用户进行正交频分复用的梳齿个数，例如：将一个物理资源块中的多个资源单元均匀交错分成两份，其中，每份资源对应一个梳齿，分别为梳齿1和梳齿2，梳齿配置信息用于指示UE可与其他用户进行正交频分复用的梳齿个数为2。
传输带宽配置信息用于指示UE进行上行参考信号发送时可使用的带宽，例如当前长期演进(Long Term Evolution，简称LTE)中的上行参考信号传输带宽可以是4个资源块(Resource Block，简称RB)，8RB，12RB，24RB中的任意一个。
跳频配置信息用于指示UE的上行参考信号发送是否进行跳频，例如：上行参考信号跳频配置信息用于指示UE进行上行参考信号跳频，或者用于指示UE不进行上行参考信号跳频。其中，所谓上行参考信号跳频指的是UE在不同发送时刻占用不同的频域资源进行上行参考信号的发送。
起始频域位置信息用于指示UE在进行上行参考信号跳频前，UE的起始频域位置。
子帧配置信息用于指示UE在进行上行参考信号发送时所占用的子帧。
符号配置信息用于指示UE在进行上行参考信号发送时所占用的符号。
具体地，下面分别以基站为每个赋形波束作用下的上行参考信号根据波束增益的不同配置不同的上行参考信号传输带宽和上行参考信号梳齿配置信息为例，进行具体说明：
例如：考虑到UE在不同发射波束下的天线增益不同，从而对应的上行参考信号传输带宽不同，因此基站为每个赋形波束作用下的上行参考信号根据波束增益的不同配置不同的传输带宽配置信息。当天线增益较小时，UE需通过较大的发射功率来补偿路径损耗，但是若功率受限时，UE发送上行参考信号的带宽会比较小，这种情况下基站为该上行参考信号发送配置较小带宽对应的传输带宽配置信息；而当天线增益较大时，UE只需通过较小的发射功率即可完成路径损耗的补偿，UE发送上行参考信号的带宽会比较大，这种情况下基站为该上行参考信号发送配置较大带宽对应的传输带宽配置信息，从而可通过较 少次数的上行参考信号发送，快速完成对全带宽信道质量信息的测量和获取。
不同的发射波束对应了不同的接收波束，将具有对应关系的接收波束和发射波束统称为收发波束对，每个收发波束对下对应的上行参考信号发送的UE数量不同，因此不同收发波束对下对应的梳齿配置信息也不同。例如：当收发波束对下对应的上行参考信号发送的UE数量较多时，较大的梳齿方式可被配置，而当收发波束对下对应的上行参考信号发送的用户数量较少时，较小的梳齿方式可被配置。
本申请提供一种上行参考信号发送方法，一方面通过波束赋形技术补偿了路径损耗，另一方面，由于基站为用户设备UE配置M个上行参考信号资源信息，以使UE根据不同的赋形波束增益采用不同的较匹配的上行参考信号资源信息发送上行参考信号，从而提高上行参考信号的发送效率。
可选地，步骤S102包括基站通过高层信令，如无线资源控制(Radio Resource Control，简称RRC)信令或者物理层信令将M个上行参考信号资源信息发送给UE；当然，也可以是基站通过专用信令发送M个上行参考信号资源信息，也就是说，该专用信令专用于发送上行参考信号资源信息，而该信令不是通信领域中已存在的信令。需要说明的是，本申请对如何发送M个上行参考信号资源信息不做限制。
可选地，基站可为每个UE配置至少一个上行参考信号进程，在该上行参考信号进程中，包括多个赋形波束对应的上行参考信号资源信息，且每套上行参考信号资源信息对应唯一的索引信息。
例如：基站为其中一个UE配置的SRS进程为：
Figure PCTCN2017109218-appb-000001
其中，SRS configuration 1、2、3和4为赋形波束1、赋形波束2、赋形波束3和赋形波束4对应的四套SRS资源信息的索引信息。
另一种可选的实施方式中，基站为UE配置至少一个上行参考信号进程，该上行参考信号进程包括至少两套上行参考信号资源信息，例如：包括两套上行参考信号资源信息，分别为第一上行参考信号资源信息和第二上行参考信号资源信息，其中，第一上行参考信号资源信息用于无赋形波束的non-precodede上行参考信号发送，而第二上行参考信号资源信息用于赋形波束的beamformed上行参考信号发送。该第一上行参考信号资源信息与该第二上行参考信号资源信息不同，所谓第一上行参考信号资源信息与第二上行参考信号资源信息不同指的是第一上行参考信号资源信息与第二上行参考信号资源信息中至少有一个字段域的配置信息是不同的。
可选地，不同系统参数下的上行参考信号发送对应不同的上行参考信号资源信息，即上行参考信号资源信息与上行参考信号发送对应的系统参数有关。这里系统参数指的是上行参考信号数据传输对应的子载波间隔等信息。例如：当在系统参数为30KHz的情况下发送上行参考信号时，则该上行参考信号发送对应的上行参考信号梳齿配置信息为：梳齿4， 当在系统参数为15KHz的情况下发送上行参考信号时，则该上行参考信号发送对应的上行参考信号梳齿配置信息为：梳齿2。不同系统参数下的上行参考信号发送的传输带宽配置信息也可不同，例如：在系统参数为30KHz的情况下发送上行参考信号时，则该上行参考信号发送对应的上行参考信号传输带宽是在系统参数为15KHz时对应的上行参考信号传输带宽的一半。
当UE从系统参数1切换到系统参数2时，则UE对应的上行参考信号资源信息也从系统参数1对应的上行参考信号资源信息切换到系统参数2对应的上行参考信号资源信息。
可选地，还包括：基站通过物理层信令，如下行控制信息(Downlink Control Information，简称DCI)指示基站当前触发的上行参考信号发送采用的上行参考信号资源信息对应的索引信息。以使UE可以根据该DCI指示所携带的索引信息确定当前发送的上行参考信号所采用的上行参考信号资源信息。
可选地，上行参考信号资源信息用于UE周期性地或者非周期性或半持续地发送上行参考信号；其中，上述DCI指示既适用于周期上行参考信号发送，也适用于非周期上行参考信号的发送。具体地，例如：DCI格式0和/或格式4中通过一个专用于上行参考信号触发的字段，如上行参考信号_request字段(2-3比特)来指示当前触发的上行参考信号发送所采用的上行参考信号资源信息对应的索引信息。可选地，DCI格式1A，2B，2C和2D中同样通过至少一个比特位指示当前触发的上行参考信号发送所采用的上行参考信号资源信息对应的索引信息。
特殊地，对于非周期性地上行参考信号发送来说，同样通过DCI指示中的至少一个比特来指示上行参考信号是否被触发，如比特0指示上行参考信号不被触发，比特1指示上行参考信号被触发。当比特1指示上行参考信号被触发时，还可以进一步通过更多的比特来指示当前触发的上行参考信号发送，所采用的上行参考信号资源信息对应的索引信息，进一步地，DCI指示还可以通过至少一个比特指示触发UE进行1次上行参考信号的发送还是连续M(M>＝1)次上行参考信号的发送，其中，每次上行参考信号的发送可以对应一个赋形波束，M次上行参考信号的发送对应了M个赋形波束的上行参考信号。可选地，这里M个赋形波束可以是M个相同的赋形波束，也可以是M个不同的赋形波束，本申请对此不做限定。
更进一步地，由于周期发送的上行参考信号通常采用无赋形波束的方式或宽波束的方式进行发送，而非周期发送的上行参考信号采用特定的细波束进行发送，周期发送的上行参考信号传输对应的波束赋形增益与非周期发送的上行参考信号传输对应的波束赋形增益不同。因此，用于周期发送的上行参考信号的上行参考信号资源信息与用于非周期发送的上行参考信号的上行参考信号资源信息不同，例如：用于周期发送的上行参考信号的上行参考信号资源信息对应的资源配置索引为1，用于非周期发送的上行参考信号的上行参考信号资源信息对应的资源配置索引为2。
可选地，还包括：基站向UE发送指示信息，所述指示信息携带在物理层信令中，用于指示所述上行参考信号发送的开始和/或所述上行参考信号发送的结束。
可选地，由于本申请可应用于大带宽和或小带宽的场景，例如：可应用于典型的高频场景，该高频场景可支持的系统带宽较大，UE扫描完整个系统带宽的时延较大，为提高UE信道估计的速度、效率以及降低UE扫描系统带宽的时延，可将全带宽上的上行参考信 号的发送和跳频集中在一个或几个子帧内的多个正交频分复用(Orthogonal Frequency Division Multiplexing，简称OFDM)符号上。因此，上述上行参考信号配置信息包括：上行参考信号子帧配置信息和上行参考信号符号配置信息，上行参考信号子帧配置信息用于指示上行参考信号发送时所占用的子帧，上行参考信号符号配置信息指示用于指示上行参考信号发送时所占用的符号和/或上行参考信号发送时所占用的符号数目。例如：图2为本申请一实施例提供的帧结构示意图，如图2所示，UE1根据基站为其配置的上行参考信号子帧配置信息和上行参考信号符号配置信息，UE1在子帧1上的OFDM符号1和OFDM符号2上发送上行参考信号。
可选地，上行参考信号符号配置信息指示用于所述UE发送上行参考信号的小区特定的第一正交频分复用OFDM符号的集合，和用于所述UE发送上行参考信号的UE特定的第二OFDM符号的集合；其中，所述第一OFDM符号的集合包括所述第二OFDM符号的集合。也就是说，由于不同UE发送上行参考信号时的传输带宽可能不同，假定每个OFDM符号内每个UE只能在一个窄带上发送上行参考信号，则不同UE遍历整个系统带宽所占用的OFDM符号个数也不同。因此，基站可根据UE的不同需求进行灵活配置，即基站为UE配置用于发送上行参考信号的小区特定的第一正交频分复用OFDM符号的集合，并为UE配置用于发送上行参考信号的UE特定的第二OFDM符号的集合。可选地，所述第一OFDM集合的配置信息包括第一OFDM符号的起始符号位置和第一OFDM符号的个数。同理，所述UE特定的第二OFDM集合的配置信息包括UE特定的第二OFDM符号的起始符号位置和UE特定的第二OFDM符号的个数。
可选地，该上行参考信号符号配置信息包括：第一指示子信息和第二指示子信息，第一指示子信息用于指示基站当前触发的上行参考信号发送采用的第一OFDM符号的集合，第二指示子信息用于指示基站当前触发的上行参考信号发送采用的UE特定的第二OFDM符号的集合；
其中，所述第一指示子信息携带在高层信令中或者物理层信令中，例如：第一指示子信息可以携带在DCI中；
所述第二指示子信息携带在高层信令中或者物理层信令中，例如：第二指示子信息也可以携带在DCI中。
例如：图3为本申请一实施例提供的基站为UE配置的第一OFDM符号的集合和第二OFDM符号的集合的示意图，如图3所示，子帧的前8个OFDM符号构成小区特定的第一OFDM符号的集合，基站为UE1配置的UE特定的第二OFDM符号的集合是第一OFDM符号集合的前4个OFDM符号，基站为UE2配置的UE特定的第二OFDM符号的集合是第一OFDM符号集合的后4个OFDM符号。由于针对不同用户的具体需求，基站可对第一OFDM符号集合内的OFDM符号进行灵活调度，因此，基于第一OFDM符号的集合和UE特定的第二OFDM符号的集合的引入可实现小区内上行参考信号复用UE个数的最大化以及最小化每个UE测量得到整个系统带宽的信道的时间。
需要说明的是，基站为UE配置用于发送上行参考信号的小区特定的第一正交频分复用OFDM符号的集合，并为UE配置用于发送上行参考信号的UE特定的第二OFDM符号的集合；不限定于赋形波束的上行参考信号发送，它还可以应用于无赋形波束的上行参考信号发送，本申请对此不做限制。
图4为本申请另一实施例提供的一种上行参考信号发送方法的示意图，如图4所示，该方法包括如下流程：
步骤S401：UE接收基站发送的M个上行参考信号资源信息；
步骤S402：UE根据不同的赋形波束增益采用不同的上行参考信号资源信息发送上行参考信号，M为大于或者等于2的正整数。
具体地，M为赋形波束的个数，也就是说，基站为每个赋形波束对应的上行参考信号资源信息根据波束增益的不同进行不同的配置，其中，该上行参考信号资源信息是指基站为UE配置的用于上行参考信号发送的资源信息，该配置的资源信息可以包括以下至少一项：上行参考信号梳齿配置信息、上行参考信号传输带宽配置信息、上行参考信号跳频配置信息、上行参考信号起始频域位置信息和上行参考信号子帧配置信息，上行参考信号符号配置信息。
本申请提供一种上行参考信号发送方法，一方面通过波束赋形技术补偿了信号传输过程中的严重路径损耗，另一方面，由于UE根据不同的赋形波束增益采用不同的上行参考信号资源信息发送上行参考信号，从而可大大提高上行参考信号的发送效率。
步骤S401的一种可选方式为：UE接收基站通过高层信令，如无线资源控制RRC信令或者物理层信令发送的M个上行参考信号资源信息。
可选地，还包括：每个上行参考信号资源信息对应唯一的索引信息；UE接收基站发送的索引信息，通过物理层信令发送的索引信息用于指示基站当前触发的上行参考信号发送采用的上行参考信号资源信息对应的索引信息。
可选地，上行参考信号资源信息用于UE周期或者非周期地发送上行参考信号；其中，用于周期发送的上行参考信号的资源信息与用于非周期发送的上行参考信号的资源信息不同。
可选地，还包括：所述UE接收所述基站发送的指示信息，所述指示信息携带在物理层信令中，用于指示所述上行参考信号发送的开始和/或所述上行参考信号发送的结束。
可选地，所述上行参考信号符号配置信息指示用于所述UE发送上行参考信号的小区特定的第一正交频分复用OFDM符号的集合，和用于所述UE发送上行参考信号的UE特定的第二OFDM符号的集合；其中，所述第一OFDM符号的集合包括所述第二OFDM符号的集合。所述上行参考信号符号配置信息包括：第一指示子信息和第二指示子信息，所述第一指示子信息用于指示所述UE发送上行参考信号采用的第一OFDM符号的集合，所述第二指示子信息用于指示所述UE发送上行参考信号采用的第二OFDM符号的集合；其中，所述第一指示子信息携带在高层信令中或者物理层信令中；所述第二指示子信息携带在高层信令中或者物理层信令中。
基于第一OFDM符号的集合和UE特定的第二OFDM符号的集合的引入可实现小区内上行参考信号复用的UE个数的最大化以及最小化每个UE测量系统带宽信道的时延。
为轮循获得最优的收发波束对信息，发射侧(如基站或UE)需进行P(P>＝1)个发射波束的扫描，此外，接收侧(如UE或基站)需进行Q(Q>＝1)个接收波束的扫描。其中，最优收发波束对的获取可通过如下几种收发波束的扫描方式：
方式一：先轮循发射波束(P次发送)，再轮循接收波束(Q次接收)；
方式二：先轮循接收波束(Q次接收)，再轮循发射波束(P次发送)；
