  • UE User Equipment
  • a Sounding Reference Signal is a signal used by a terminal device and a base station to measure Channel State Information (CSI).
  • the UE periodically sends an uplink SRS on the last data symbol of the transmission subframe according to parameters such as bandwidth indicated by the eNB, frequency domain location, sequence cyclic shift, period, and subframe offset.
  • the eNB determines the uplink CSI of the UE according to the received SRS, and performs operations such as frequency domain selection scheduling, closed loop power control, and the like according to the obtained CSI.
  • SRS transmission needs to cover the frequency band of interest in the frequency domain. This can be achieved in two ways: one by covering a whole band by transmitting a sufficiently large wideband SRS; the other is by transmitting multiple narrowband SRSs. And hopping in the frequency domain, and then combining a series of sent SRSs, can cover the entire bandwidth.
  • multiple UEs may use different cyclic shifts on the same frequency comb, and then send SRS through code division multiplexing, or two UEs may be combed on different frequencies and transmitted by frequency division multiplexing.
  • SRS SRS.
  • a UE that transmits an SRS in a certain SRS bandwidth (an integer multiple of four RBs) has eight cyclic shifts and two frequency combs that can be used, so the UE is said to be UE.
  • There are a total of 16 resources that can be used to send SRS that is, up to 16 SRSs can be sent simultaneously within this SRS bandwidth.
  • the uplink single-user multiple input multiple output (SU-MIMO) is not supported in the LTE system, only one SRS can be transmitted by the UE at a time, so only one SRS resource is required for one UE. Therefore, within the above SRS bandwidth, the system can simultaneously multiplex up to 16 UEs.
  • SU-MIMO uplink single-user multiple input multiple output
  • LTE In LTE, up to two antennas can be used as the uplink transmit antenna.
  • LTE supports two antenna users to transmit SRS by using the antenna selection function, that is, two antenna SRS switching transmission.
  • the UE For the specified SRS bandwidth, the UE transmits the SRS on only one antenna at the same time, and the two antennas transmit the SRS in turn to complete the channel quality information detection of the two antenna SRS.
  • the LTE-Advanced (LTE-A) system is a next-generation evolution system of the LTE system, supports SU-MIMO in the uplink, and can use up to four antennas as uplink transmitting antennas. That is, the UE can simultaneously transmit SRS on multiple antennas at the same time, and the eNB needs to estimate the state on each channel according to the SRS received on each antenna.
  • non-pre-coded (ie, antenna-specific) SRS should be used.
  • the UE transmits the non-precoded SRS by using multiple antennas, the SRS resources required by each UE are increased, which results in a decrease in the number of UEs that can be simultaneously multiplexed in the system.

  • LTE Release 13 In the future research of LTE-A Release 13 (LTE Release 13), in the scenario of configuring MIMO (Full Dimension-MIMO, FD-MIMO for short) or MIMO (Massive-MIMO) for a large number of antennas, TDD channel reciprocity increases the demand for SRS measurement and the number of multiplexed users increases.
  • the existing SRS multiplexing capacity has become difficult to meet the demand.
  • it is a research direction to enhance the multiplexing capacity of SRS by introducing SRS switching transmission for more antennas (for example, four antennas).
  • LTE adopts two schemes of open loop and closed loop antenna selection for uplink transmission of user equipment.
  • the device can freely select the transmit antenna without the need for an indication from the base station.
  • the SRS transmission serves as a reference for selecting the uplink
  • the base station performs antenna selection based on the SRS channel measurement result and indicates the antenna selection information to the terminal. Since the correlation of multiple antennas of the user equipment is not large in a rich scattering environment, the channel estimation quality of the multiple antennas is different, sometimes even very different. Selecting an antenna with better channel estimation quality for uplink transmission is an effective segment to improve uplink data transmission performance. Therefore, after introducing SRS handover transmission for more antennas, how the base station indicates the transmission antenna for uplink transmission selected by the SRS measurement result to the terminal is a problem to be solved, and is not in the prior art.

Description

天线选择信息的指示方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种天线选择信息的指示方法及装置。
背景技术
长期演进(Long Term Evolution，简称为LTE)系统中，物理下行控制信道(Physical Downlink Control Channel，简称为PDCCH)用于承载下行控制信息，以及上行功率控制信息。下行控制信息(Downlink Control Information，简称为DCI)格式(format)分为DCI format 0、1、1A、1B、1C、1D、2、2A、3、3A等。下行控制信息包括上行授权信息和下行授权信息，其中下行授权信息主要用于调度下行链路传输，对应的下行控制信息格式包括DCI format 1、1A、1B、1C、1D、2、2A、3、3A等，而上行授权信息主要用于调度上行链路传输，对应的下行控制信息格式包括DCI format 0等。基站(e-Node-B，简称为eNB)可以通过下行控制信息配置终端设备(User Equipment，简称为UE)，或者终端设备接收高层(higher layers)的配置，也称为通过高层信令来配置UE。
LTE系统中，测量参考信号(Sounding Reference Signal，简称为SRS)是一种终端设备与基站间用来测量无线信道信息(Channel State Information，简称为CSI)的信号。在长期演进系统中，UE按照eNB指示的带宽、频域位置、序列循环移位、周期和子帧偏置等参数，定时在发送子帧的最后一个数据符号上发送上行SRS。eNB根据接收到的SRS判断UE上行的CSI，并根据得到的CSI进行频域选择调度、闭环功率控制等操作。
在频域上，SRS传输需要覆盖频域所关心的频段，这可以通过两种方式实现：一种通过发送一个足够大的宽带SRS，来覆盖整个频段；另一种是通过发送多个窄带SRS，并在频域上进行跳频(hopping)，然后将一连串发送的SRS联合起来，就能覆盖整个带宽。
在同一SRS带宽内，多个UE可以在同一个频率梳上使用不同的循环移位，然后通过码分复用发送SRS，也可以两个UE在不同的频率梳上，通过频分复用发送SRS。具体来说，在LTE系统中，在某个SRS带宽(4个RB的整数倍)内发送SRS的UE，可以使用的循环移位有8个，可以使用的频率梳为2个，所以说UE共有16个可用来发送SRS的资源，也就是说，在这一SRS带宽内，最多可以同时发送16个SRS。由于在LTE系统中不支持上行单用户多输入多输出(Single User Multiple Input Multiple Output，简称为SU-MIMO)，UE在每一时刻只能有一根发送SRS，所以一个UE只需要一个SRS资源。因此，在上述SRS带宽内，系统最多可以同时复用16个UE。
LTE中，最多可以使用两根天线作为上行发射天线。LTE支持两天线用户利用天线选择功能发送SRS，即两天线SRS切换发送。对于指定的SRS带宽，UE在同一个时刻仅在一个天线上发送SRS，两个天线轮流发送SRS，完成两天线SRS的信道质量信息探测。
高级LTE(LTE-Advanced，简称为LTE-A)系统是LTE系统的下一代演进系统，在上行支持SU-MIMO，并且最多可以使用4根天线作为上行发射天线。也就是说，UE在同一时刻可以在多根天线上同时发送SRS，而eNB需要根据每根天线上收到的SRS来估计每条信道上的状态。
在现有的LTE-A的研究中提出：在上行通信中，应该使用非预编码(即天线专有)的SRS。此时，当UE使用多天线发送非预编码的SRS时，每个UE所需要的SRS资源都会增加，也就造成了系统内可以同时复用的UE数量下降。此外，除了保留LTE原有的周期(periodic)发送SRS，还可以通过下行控制信息或者高层信令配置UE非周期(aperiodic)发送SRS。
例如，在某个SRS带宽(4个RB的整数倍)内，如果每个UE都使用4个天线发送SRS，那么每个UE所需要的资源数就是4个。根据上述一个SRS带宽内所能支持的SRS资源数总共为16个，那么在这个SRS带宽内，可以复用的UE数就减少为4个。系统内可以同时复用的用户数将为原来的1/4。在现有的LTE-A Release 10(LTE-A版本10)的研究中提出，UE可通过高层信令(也称为通过trigger type 0触发)或下行控制信息(也称为通过trigger type 1触发)这两种触发方式发送SRS，基于高层信令触发的为周期SRS，基于下行控制信息触发的为非周期SRS(Aperiodic SRS，简称为A-SRS)。在LTE-A Release 10中增加了非周期发送SRS的方式，一定程度上改善了SRS资源的利用率，提高资源调度的灵活性。
在未来LTE-A Release 13(LTE版本13)的研究中，在配置完整维度的MIMO(Full Dimension-MIMO，简称为FD-MIMO)或大量天线的MIMO(Massive-MIMO)的场景下，随着TDD信道互易性对SRS测量需求的增加以及复用用户数的增多，现有的SRS复用容量已经变得很难满足需求。现有的研究中，通过引入针对更多天线(例如四天线)的SRS切换发送来增强SRS的复用容量是一大研究方向。
在现有技术中，LTE采用开环和闭环天线选择两种方案，来为用户设备进行上行链路传输。在选择开环天线的情况下，用于设备可自由选择传输天线，而不需要来自基站的指示。在选择闭环天线的情况下，SRS传输作为选择上行链路的参考，基站根据SRS信道测量结果进行天线选择，并将天线选择信息指示给终端。由于在富散射环境中，用户设备的多个天线的相关性不大，导致这多个天线的信道估计质量不同，有时甚至差别很大。选择信道估计质量较优的天线用于上行传输是提高上行数据传输性能的一种有效有段。因此，在引入针对更多天线的SRS切换发送之后，基站如何将通过SRS测量结果选择的用于上行链路传输的发送天线指示给终端是一个需要解决的问题，而在现有技术中并不存在相关的指示方法。
针对相关技术中存在的基站无法将选择的天线的信息指示给终端，从而造成上行链路传输性能低的问题，目前尚未提出有效的解决方案。

比特获得终端天线选择后的天线组索引信息。
或者可选地，基站通过1比特高层信令向终端指示终端的天线选择信息是以天线为单位的还是以天线组为单位的；若是以天线为单位，则基站通过下行控制信息中的上行授权信息的循环冗余校验码(Cyclic Redundancy Check，简称为CRC)的N个不同扰码向终端指示天线索引信息；若是以天线组为单位，则基站通过下行控制信息中的上行授权信息的CRC的M个不同扰码向终端指示天线组索引信息。终端通过接收高层信令获知天线选择信息是基于天线为单位还是基于天线组为单位的，若是以天线为单位，则终端通过对下行控制信息中的上行授权信息的CRC的N个不同扰码进行盲检测获得终端天线选择后的天线索引信息；若是以天线组为单位，则终端通过对下行控制信息中的上行授权信息的CRC的M个不同扰码进行盲检测获得终端天线选择后的天线组索引信息。
方式二：
基站通过下行控制信息中的上行授权信息向终端同时指示天线索引信息及天线组索引信息。该方法能够实现终端使用一个天线发送上行链路或者使用一组天线发送上行链路之间的动态切换。

方式四：
基站通过下行控制信息中的上行授权信息向终端指示天线组索引信息。该方法的前提是，基站和终端都默认天线选择信息是以天线组为单位的，而且天线组的划分是预先规定好的(预先规定好的可以是基站和终端预先协商好的，或者是一方进行确定后再指示给另一方，或者是通过其他的网元确定的，或者是人工配置的等等)，基站和终端已知的。通过这种方式，终端能够支持一个时刻在多个最优天线上发送上行链路，有利于支持终端的MIMO发送；另一方面，该方式也有助于支持SRS以天线组为切换发送单位，因此有利于节省SRS的切换发送时延。
可选地，基站通过下行控制信息中的上行授权信息中的
Figure PCTCN2016105912-appb-000039
比特向终端指示天线组索引信息。终端通过接收下行控制信息中的上行授权信息中的用于指示天线选择信息的
Figure PCTCN2016105912-appb-000040
比特获得终端天线选择后的天线组索引信息。
或者可选地，基站通过下行控制信息中的上行授权信息的CRC的M个不同扰码向终端指示天线组索引信息。终端通过对下行控制信息中的上行授权信息的CRC的M个不同扰码进行盲检测获得终端天线选择后的天线组索引信息。
或者可选地，基站通过下行控制信息中的上行授权信息中的用于触发非周期SRS发送的比特位同时用于向终端指示天线组索引信息。终端通过接收下行控制信息中的上行授权信息中的用于触发非周期SRS发送的比特位获得终端天线选择后的天线组索引信息。
在以上各方式中，优选地，N等于4；优选地，上述下行控制信息中的上行授权信息至少包括DCI format 0或者DCI format 4。
下面为了进一步更加具体说明本发明实施例中方法，以终端具有四个天线(N＝4)的情况为例：
相关技术中，循环冗余校验码(Cyclic Redundancy Check，简称为CRC)检验原理实际上就是在一个A位二进制数据序列之后附加一个L位二进制检验码(序列)，从而构成一个总长为B＝A+L位的二进制序列；附加在数据序列之后的这个校验码与数据序列的内容之间存在着某种特定的关系。如果因干扰等原因使数据序列中的某一位或某些位发生错误，这种特定关系就会被破坏。因此，通过检查这一关系，就可以实现对数据正确性的检验。
LTE系统采用了四种格式的CRC：CRC24A、CRC24B、CRC16、CRC8。其生成多项式如下：
CRC24A：g(D)＝[D24+D23+D18+D17+D14+D11+D10+D7+D6+D5+D4+D3+D+1]；
CRC24B：g(D)＝[D24+D23+D6+D5+D+1]；
CRC16：g(D)＝[D16+D12+D5+1]；
CRC8：g(D)＝[D8+D7+D4+D3+D+1]。
其中，CRC长度为24的CRC-24A和CRC-24B主要用于共享数据信道传输，长度为16的CRC-16主要用于下行控制信道和广播数据信道传输，长度为8的CRC-8主要用于信道质量信息(Control Quality Information，简称为CQI)信息的传输。
LTE系统中，下行控制信息中的上行授权信息主要用于调度上行数据。在LTE系统中，用户设备最多配置两个天线，上行数据主要通过下行控制信息中的上行授权信息DCI format 0来调度。在LTE-A系统中，用户设备最多可配置四个天线，当用户设备配置四个天线时，该用户设备的上行数据主要通过下行控制信息中的上行授权信息DCI format 4来调度。
相关技术中，上行授权信息DCI format 4的CRC校验码采用用户的无线网络临时标识(Radio Network Temporary Identifier，简称为RNTI)进行了加扰。如上所述，DCI format 4的CRC校验码是16位的，假设DCI format 4加入CRC校验码之后的比特序列为bk(0≤k≤A+15)，用户所对应的RNTI为xrnti,0,xrnti,1,...,xrnti,15，其中xrnti,0是RNTI的最高有效位(Most Significant Bit，简称为MSB)，则经过RNTI加扰后的DCI format 4的比特序列为：
ck＝bk     对于k＝0,1,2,…,A-1；
ck＝(bk+xrnti,k-A)mod 2  对于k＝A,A+1,A+2,...,A+15。
当UE的四天线天线选择功能或者闭环天线选择功能使能时，基站可以通过该UE的上行授权信息DCI format 4来向它指示所选择的天线信息。UE根据最近一次接收到的DCI format 4的指示信息，选择天线发送上行数据或SRS，可选地：
上行授权信息DCI format 4的采用用户的RNTI和天线信息共同对CRC校验码进行加扰处理。假设用户的四天线信息比特位用xrnti,0,xrnti,1,...,xrnti,15来表示，则经过RNTI和天线信息共同加扰后的DCI format 4的比特序列为：
ck＝bk     对于k＝0,1,2,…,A-1；
ck＝(bk+xrnti,k-A+xAS,k-A)mod 2  对于k＝A,A+1,A+2,...,A+15。
其中，四天线信息比特位用于向UE指示UE的天线选择信息。
可选地，UE的四天线信息比特位以及所指示的天线选择信息如下面的表格1或者表格2或者表格3所示：

当然，考虑到后向兼容性，当终端具有四个天线时，它的数据也可能是通过DCI format 0来调度的。因此当终端具有四个天线时，天线选择信息也可能会通过DCI format 0的CRC的扰码来指示。基站通过上行授权信息DCI format 0向终端指示其四天线选择信息的过程与上行DCI format 4向终端指示其四天线选择信息的过程相同。
或者，基站可以通过高层信令通知UE的天线选择信息是以天线为单位或是以天线组为单位。若以天线为单位，则“天线选择信息比特位”和“UE天线选择信息”之间的对应关系按照表格1通知给UE，并且UE按照表格1进行对天线选择信息进行盲检测；若以天线组为单位，则“天线选择信息比特位”的“UE天线选择信息”之间的对应关系按照表格2通知给UE。
在另一个可选的实施例中，基站可以将UE的四天线选择信息通过下行控制信息中的上行授权信息直接指示给UE。可选地，基站可以通过在上行授权信息中新增加2比特或者1比特或者3比特用于向UE指示四天线选择信息，例如表格4或者表格5或者表格6所示：
表格4
Figure PCTCN2016105912-appb-000044
或者，
表格5
Figure PCTCN2016105912-appb-000045
或者，
表格6
Figure PCTCN2016105912-appb-000046
或者，基站可以通过高层信令通知UE的天线选择信息是以天线为单位或是以天线组为单位。若以天线为单位，则“上行授权信息中的比特位”和“UE天线选择信息”之间的对应关系按照表格4通知给UE，并且UE按照表格4进行对天线选择信息进行盲检测；若以天线组为单位，则“上行授权信息中的比特位”的“UE天线选择信息”之间的对应关系按照表格5通知给UE。
在另一个可选的实施例中，基站可以将UE的四天线选择信息通过下行控制信息中的上行授权信息中用于触发非周期SRS(Aperiodic SRS，简称为A-SRS)的比特位指示给UE。优选地，基站可以通过上行授权信息DCI format 4中的用于触发A-SRS的两个比特同时用于向UE指示其四天线选择信息。例如，现有技术中用于触发A-SRS的两个比特所指示的信息如表格7所示：
表格7
A-SRS触发比特 描述
'00' 不触发A-SRS
'01' 触发并使用高层配置的第一套A-SRS参数
'10' 触发并使用高层配置的第二套A-SRS参数
'11' 触发并使用高层配置的第三套A-SRS参数
通过上述用于触发A-SRS的两个比特同时用于指示UE的四天线选择信息，如表格8所示：
表格8
A-SRS触发比特 描述
'00' 不触发A-SRS(UE第一天线)
'01' 触发并使用高层配置的第一套A-SRS参数(UE第二天线)
'10' 触发并使用高层配置的第二套A-SRS参数(UE第三天线)
'11' 触发并使用高层配置的第三套A-SRS参数(UE第四天线)
其中，UE第二天线索引信息也可以包含在高层配置的第一套A-SRS参数中，UE第三天线索引信息也可以包含在高层配置的第二套A-SRS参数中，UE第四天线索引信息也可以包含在高层配置的第三套A-SRS参数中，此外，当A-SRS触发比特为‘00’即不触发A-SRS时，UE默认在第一天线上发送数据或SRS(包括P-SRS和/或A-SRS)。
其中，在基站向终端指示四天线选择信息之前，基站可以通过高层信令向UE指示是否支持四天线的天线选择功能，和/或，基站可以通过高层信令通知UE是否开启针对四天线的闭环天线选择功能，和/或，基站可以通过高层信令向UE指示开启四天线的开环天线选择功能还是闭环天线选择功能。
