Abstract

Description

一种被用于动态调度的用户设备、基站中的方法和装置 技术领域
本发明涉及无线通信***中的传输方法和装置，尤其涉及被用于动态调度的无线通信中控制信道的传输方法和装置。
背景技术
现有的LTE(Long Term Evolution，长期演进)***中，对于一个下行子帧而言，UE会在所述下行子帧中搜索对应的DCI(Downlink Control Information，下行控制信息)。考虑到DCI传输的鲁棒性(Robustness)以及高覆盖性需求，DCI对应的PDCCH(Physical Downlink Control Channel，物理下行控制信道)或者EPDCCH(Enhanced Physical Downlink Control Channel，增强的物理下行控制信道)往往通过分集(Diversity)或者预编码循环(Precoder Cycling)的方式传输。
未来移动通信***中，由于波束赋型(Beamforming)和大规模多天线***的引入(Massive-MIMO)。控制信令将会以波束赋型的方式传输，相应的，控制信令的传输方式以及对应的搜索空间(Search Space)将会被重新考虑。
发明内容
一种简单的控制信令的传输方式就是将控制信令采用的发送波束的方向或者索引在UE接收之前指示UE。比如控制信令分别在两个波束上传输，基站就将此信息在UE对所述控制信令进行盲检测(Blind Decoding)之前告诉UE。然而，此种方法存在一个显著的问题，即增加了额外的信令开销，特别是当发送所述控制信令的波束是动态变化时，此种方式会带来额外的控制信令的开销。同时考虑到此信息需要在接收控制信令之前被完成接收，以现有LTE***的特点，此信息往往是非UE专属的(Non UE-Specific)，而非UE专属的信息会进一步带来额外的物理层控制信令的开销和实现复杂度。
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动态调度的UE中的方法，其中，包括如下步骤：
-步骤A.在第一时频资源池中接收第一RS集合；
-步骤B.搜索第一信令。
