Description
本申请涉及通信领域,并且更具体地,涉及一种无线通信方法、终端设备和网络设备。
在典型无线通信网络(比如,长期演进(Long Term Evolution,简称为“LTE”网络)中,上行数据共享信道(Shared Data Channels)的选择基于调度/准许(Scheduling/Grant)机制,完全受基站(Base Station,简称为“BS”)控制。在该机制中,用户设备(User Equipment,简称为“UE”)首先向BS发出上行调度请求。当BS接收到该请求后,向UE发出上行Grant以通知该UE为该UE分配给的上行传输资源。UE据此在经过准许的上行传输资源上进行数据传输。
大规模用户接入是下一代通信网络的典型应用场景之一。当海量用户接入时,如果沿用上述Scheduling/Grant机制,则一方面将导致巨大的信令传输开销以及BS资源分配的调度压力,另一方面将造成显著的传输时延。鉴于此,下一代通信网络为支撑海量用户接入将采用基于竞争的接入(contention based access)方式。
而在基于竞争的接入方式中,可以将半静态资源配置给一组终端设备,如果多个终端设备在相同的资源上同时传输数据,则会出现竞争冲突。因此,如何实现在基于竞争的接入方式中,避免竞争冲突是一项亟待解决的问题。

为了便于更加清楚地理解本申请,以下将结合图4和表1描述根据本申请实施例的通信方法。
网络半静态配置好上行竞争资源给一组UE,比如,如图4所示,对于半静态配置上行资源3和上行资源4,网络给其配置了一组UE(UE1,UE2,UE3,…,UE7);其中,上行资源3用于该组UE进行探测信号的传输,上行传输4用于该组终端进行上行数据的传输。收到相应的配置信息之后,这7个UE将在半静态配置资源3上发送探测信号,用于竞争半静态资源4中的资源(应理解,并不是每个UE都在资源4这个时频资源上有待传数据,如果没有,则无需在资源4上发送探测信号)。首先,有数据要传的UE根据预先配置规则,比如UE ID取模得出UE在资源3上的传输时隙,根据规则,不同UE的探测信号的时隙和竞争的时隙可以如表1所示。其次,UE将在确定好的时隙上传输探测信号,其中包含UE ID,其目的是为了网络能够区分在同一时隙上配置多个UE传输的情况(比如对于slot1,UE 1和UE 6都可以传输探测信号)。再次,传输完探测信号的UE将触发定时器,在规定时间内监测网络侧对探测信号的反馈信号,成功接收到反馈信号的UE即竞争成功。
表1
UE ID | 探测信号的时隙 | 竞争的时隙 |
1 | 时隙1 | 时隙1 |
2 | 时隙2 | 时隙2 |
3 | 时隙3 | 时隙3 |
4 | 时隙4 | 时隙4 |
5 | 时隙5 | 时隙5 |
6 | 时隙1 | 时隙1 |
7 | 时隙2 | 时隙2 |
应理解,以上结合图4和表1描述的实施例,仅仅是为了读者更加清楚地理解本申请,不应对本申请实施例的范围造成特别限定。
例如,资源3和资源4可以是时域上连续的资源,资源3在时域上早于资源4。
再例如,资源4和资源3的时隙数量可以是不同的,具体可以由网络设备根据实际情况配置。
再例如,资源4和资源3可以占用不同的子带。
因此,在本申请实施例中,在确定有待发送的上行数据时,终端设备向网络设备发送用于竞争第一预配置资源探测信号,在所述终端设备接收到所述网络设备用于指示所述第一预配置资源被所述终端设备竞争时,在所述第一预配置资源上,发送所述待发送的上行数据,可以避免资源的竞争冲突。
