Description

一种无线通信中的UE和基站中的方法和装置 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，特别是涉及基于蜂窝网通信的上行传输及下行反馈的方法和装置。
背景技术
传统的基于数字调制方式的无线通信系统，例如3GPP(3rd Generation Partner Project，第三代合作伙伴项目)蜂窝系统中，上行无线信号的发送是基于基站的调度。而对下一代无线通信系统而言，IoT(Internet of Things，物联网)通信可能会成为一个重要的应用场景。
IoT通信的特征包括：终端设备的数量非常巨大，终端设备所支持的待机时间较长(功耗要低)，终端设备的成本较低等方面。传统的基于调度的上行发送不再适用于IoT，原因包括：
-.下行调度所需要的信令会严重降低传输效率。尤其考虑到典型的一次IoT的上行发送所包括的信息比特数量通常比较少。
-.增加终端设备的功耗，降低待机时间。现有的系统中，终端设备首先通过例如SR(Scheduling Request，调度请求)等信令，然后才能发送上行传输。
-.增大了上行传输延时。一些特殊场景中，IoT通信需要较低的传输延时，而现有的基于调度的上行传输不能满足这一需求。
针对上述问题，CB(Contention Based，基于竞争的)上行传输被提出，即UE不需要基站的调度即可发送上行信息。如果没有发生(两个或者多个UE之间的)冲突，则基站能够正确译码上行信息。
发明内容
发明人通过研究发现，CB上行传输的好处之一在于，当基站所需服务的用户数较多，且每个用户所需的时频资源较小时，CB上行传输可以有效的降低控制信令的开销和控制信令的碰撞。然后，CB上行传输也会存在一个显著的问题，即当有多个UE同时选择同一块资源进行上行传输时，而基站只解码出了所述多个UE中的部分UE的上行数据，并发送 对应的HARQ-ACK(Hybrid Automatic Repeat request-Acknowledgement，混合自动重传请求确认)时，所述多个UE无法知道基站发送的HARQ-ACK中哪一个是其自己的。上述问题的一个简单的方法，就是基站预留足够多的资源用于CB上行传输，且基站也同时预留与上行资源匹配的下行资源发送对应的HARQ-ACK。但是这样当没有较多UE进行CB传输时，这些预先配置的资源会产生严重的浪费，且这个方法本身也违背了CB上行传输的设计初衷。
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无线通信的UE中的方法，其中，包括如下步骤：
-步骤A.在第一时频资源中发送第一无线信号
-步骤B.在第二时频资源中检测第一信令。
其中，所述第一时频资源是由所述UE自行选择的，所述第一无线信号被用于确定{第一参数集合，第一数据}。所述第一参数集合被用于确定{所述第二时频资源，所述第一信令}中的至少之一。所述第一参数集合包括{第一标识，第二标识}中的至少之一，所述第一标识是整数，所述第二标识是整数。所述第一信令是物理层信令，所述第一信令被用于确定第三标识。
作为一个实施例，传统的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，UE的上行传输均需要通过基站调度完成，因此，无论是通过DCI(Downlink Control Information，下行控制信息)中的NDI(New Data Indicator，新数据指示)隐性的发送下行的HARQ-ACK；或者通过PHICH(Physical Hybrid ARQ Indicator Channel，物理混合自动重传请求指示信道)显性的发送下行的HARQ-ACK，UE总是可以在已知的时频资源上去接收上行传输的HARQ-ACK，从而确定上行数据是否被基站正确接收。然而，CB上行传输，如果UE1和UE2同时选择了同一块时频资源并发送各自的上行数据，而基站只检测出了UE1的数据，并反馈下行HARQ-ACK。如果UE2也接收到这个HARQ-ACK，则UE2会认为它的上行数 据被基站正确接收，进而带来HARQ误检测，对性能产生影响。
作为一个实施例，上述方法中的第二标识和第三标识的设计，即解决了上述问题。所述第二标识是UE唯一的标识，即保证每个UE对应的第二标识均是不一样的。UE在发送上行数据时，将自己的第二标识也发送给基站，基站在发送反馈的第一信令时，将自己检测到的第三标识也同时反馈。如果第三标识和第二标识相同，则证明这个反馈是针对发送第二标识的UE的，且发送第二标识的UE的上行数据被正确接收；如果第三标识和第二标识不同，则证明这个反馈是发送给其他UE的，且发送第二标识的UE的上行数据没有被正确接收。
作为一个实施例，上述方法的另一个特质是将所述第一参数集合被用于确定{所述第二时频资源，所述第一信令}中的至少之一。这样的好处在于，当UE生成第一参数集合时，UE就会知道在哪里接收第一信令，以及第一信令所采用的扰码，或者扩频序列等信息，进而避免UE在较大的时频资源中完全盲检测第一信令，降低UE复杂度，更加节电。
