Description

一种无线传输中的方法和装置 技术领域
本发明涉及无线通信系统中的无线信号的传输方案，特别是涉及支持低延迟通信的基站及UE中的方法和装置。
背景技术
现有的LTE(Long-term Evolution，长期演进)及LTE-A(Long Term Evolution Advanced，增强的长期演进)系统中，TTI(Transmission Time Interval，传输时间间隔)或者子帧(Subframe)或者PRB(Physical Resource Block，物理资源块)对(Pair)在时间上对应一个ms(milli-second，毫秒)。一个LTE子帧包括两个时隙(Time Slot)，分别是第一时隙和第二时隙，且所述第一时隙和所述第二时隙分别占用一个LTE子帧的前半个毫秒和后半个毫秒。
传统的LTE系统，当引进CA(Carrier Aggregation，载波聚合)机制时，为保证UCI(Uplink Control Information，上行控制信息)在基站侧的正确接收，定义了功率标定(Power Scaling)的相关策略。具体方式是：当在同一时刻存在多个载波同时发送，发送PUCCH(Physical Uplink Control Channel，物理上行控制信道)的载波在功率分配上的优先级大于发送PUSCH(Physical Uplink Shared Channel，物理上行共享信道)的载波；以及发送包含UCI的PUSCH的载波在功率分配上的优先级大于发送不包含UCI的PUSCH的载波。
3GPP(3rd Generation Partner Project，第三代合作伙伴项目)Release 14中的Reduced Latency(降低延迟)以及新一代的无线接入技术(NR，New Radio access technologies)中，一个重要的应用场景就是URLLC(Ultra-Reliable and Low Latency Communications，超高可靠性和低延迟通信)。针对Reduced Latency以及URLLC的场景，一种新的时间间隔，即sTTI(Short Transmission Time Interval，短传输时间间隔)被引入，相应的传统功率标定的方法需要被重新设计。
发明内容
研究人员发现，当多个载波上采用不同持续时间的sTTI用于上行传输时，一个长sTTI的数据传输可能针对多个短sTTI的传输，且所述短sTTI的传输中，一些是上行控制信道，一些是包含上行控制信息的数据信道，而剩下的一些又是纯上行数据信道，且这种不同的信道组合可能是动态变化的。因此，传统的功率标定方式，所述长sTTI的传输所采用的功率选择就成为一个问题。
一种直观的方式，两个载波均分UE所能支持的最大发送功率。然而此种方法一个最直接的问题，就是会降低上行控制信道的发送功率，进而影响上行控制信道的性能。
针对上述问题，本发明提供了解决方案。需要说明的是，在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。例如，本申请的UE中的实施例和实施例中的特征可以应用到基站中，反之亦然。
本发明公开了一种被用于低延迟通信的UE中的方法，其中，包括如下步骤：
-步骤A.发送Q个指示信息；
-步骤B.在第一载波上发送第一参考信号以及第一无线信号。
其中，所述第一无线信号携带{第一比特块，第一UCI}中的至少之一。所述第一无线信号被第一天线端口组发送。所述第一天线端口组包括P个天线端口，所述P是正整数。所述第一参考信号包括P个RS端口，所述RS端口分别被所述P个天线端口发送。所述第一无线信号包括L个子无线信号，所述L个子无线信号分别占用L个时间间隔，所述L是大于1的正整数。所述Q个指示信息分别被用于确定在Q个时间间隔中的所述第一无线信号的发送功率和所述第一参考信号的发送功率的比值。所述Q个时间间隔是所述L个时间间隔的Q个。所述Q是小于或者等于所述L的正整数。
传统的LTE及LTE-A系统中，功率标定是基于每个SF(Subframe，子帧)进行的，且在不同额载波上，UE只会在一个子帧中传输一种物理信道。而当UE同时支持sTTI和CA，且各个载波上sTTI的配置不同时，在一个子帧中，UE在不同的sTTI上可能会传输不同的上行信道，且一个载波中的一个长sTTI将会对应另一个载波上承载多个不同物理信道 的短sTTI。传统的功率标定的方式将不能适用。
本发明设计的上述方法通过设计Q个指示信息，从而实现在Q个时间间隔中的所述第一无线信号的发送功率在每个时间间隔上进行调整，以适应与所述Q个时间间隔对应的另一个载波上的物理信道传输的种类，进而保证上行控制信息被基站正确接收。
