  • 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.

  • a big technical challenge faced by high-frequency carrier communication is that relatively low-frequency signals, the fading of high-frequency signals in space is very large, although the high-frequency signals in the outdoor communication have a spatial fading loss problem, but because of With its wavelength reduction, more antennas can usually be used so that communication can be based on the beam to compensate for fading losses in space.
  • SRS may also be transmitted by using a beam, and may be transmitted only in some beams. If the prior art is used, the timing sends the uplink SRS on the last data symbol of the transmitting subframe, and the receiving end can periodically receive the SRS on the last data symbol of the transmitting subframe, which makes the transmission flexibility of the SRS. It is greatly restricted.
  • SRS uses beam transmission and omnidirectional transmission of SRS. There are actually many changes in transmission parameters. If the receiver receives the beam according to the existing reception mode, it may cause reception of SRS. Poor quality, for example, cannot be successfully received or successfully decoded, resulting in problems such as failure of wireless channel measurements.

Description

上行参考信号信息的指示方法及装置和存储介质
本申请基于申请号为201710014453.3、申请日为2017年01月09日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及通信领域，具体而言，涉及一种上行参考信号信息的指示方法及装置和存储介质。
背景技术
在相关技术中，在长期演进(Long Term Evolution，简称为LTE)中，物理下行控制信道(Physical Downlink Control Channel，简称为PDCCH)用于承载上、下行调度信息，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，后面演进至LTE-A Release 12(LTE-A版本12)中又增加了DCI format 2B、2C、2D以支持多种不同的应用和传输模式。演进型节点B(e-Node-B，简称为eNB)或者基站可以通过下行控制信息配置终端设备(User Equipment，简称为UE)，或者终端设备接受高层(higher layers)的配置，也称为通过高层信令来配置UE。
上行参考信号可以包含多种类型的信号，在相关技术中，上行参考信号的发送存在一些问题，下面以测量参考信号为例进行说明：
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指示的频带、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。
在现有的LTE-A Release 10(LTE-A版本10)的研究中提出：在上行通信中，应该使用非预编码的SRS，即：天线专有的SRS，而对PUSCH的用于解调的参考信号(De Modulation Reference Signal，简称为DMRS)则进行预编码。基站通过接收非预编码的SRS，可估计出上行的原始CSI，而经过了预编码的DMRS则不能使基站估计出上行原始的CSI。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。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。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。
随着通信技术的发展，数据业务需求量不断增加，可用的低频载波也已经非常稀缺，由此，基于还未充分利用的高频(30-300GHz)载波通信成为解决未来高速数据通信的重要通信手段之一。高频载波通信的可用带宽很大，可以提供有效的高速数据通信。但是，高频载波通信面临的一个很大的技术挑战就是：相对低频信号，高频信号在空间的衰落非常大，虽然会导致高频信号在室外的通信出现了空间的衰落损耗问题，但是由于其波长的减小，通常可以使用更多的天线，从而可以基于波束进行通信以补偿在空间的衰落损耗。
但是，当天线数增多时，由于此时需要每个天线都有一套射频链路，基于数字波束成型也带来了增加成本和功率损耗的问题。因此，目前的研 究中比较倾向于混合波束赋形，即射频波束和数字波束共同形成最终的波束。
随着波束赋形技术的发展，导致SRS也可能是利用波束发送的，而且可能是仅在一些波束发送。若沿用现有技术中，定时在发送子帧的最后一个数据符号上发送上行SRS，而接收端可以定时在发送子帧的最后一个数据符号上接收到SRS，一方面使得SRS的发送的灵活性受到了很大限制，另一方面，SRS采用波束发送与全向发送SRS实质上还有很多传输参数的变化，若接收端还是按照现有的接收方式接收波束，则有可能会导致SRS的接收质量差，例如，无法成功接收或成功解码，从而导致无线信道测量的失效等问题。
发明内容
本发明实施例提供了一种上行参考信号信息的指示方法及装置以及上行参考信号的发送方法及装置，以至少解决相关技术中存在的发送上行参考信号所存在的问题。

工业实用性
本发明实施例中改变了现有技术中接收端直接在发送子帧的最后一个数据符号上定时接收SRS的方式，而是在需要接收SRS之前通过上行参考信号信息向发送端指示SRS的发送参数，例如，发送资源以及信号类型等，一方面相对于在预定的发送子帧上固定接收SRS，提高了SRS传输的灵活性，另一方面，可以确保SRS传输的成功率，故具有积极的工业效果。与此同时，发送端可以通过上行参考信号信息的发送，就可以告知发送端SRS 的发送参数，故具有实现简便的特点，可在工业上大规模应用。
