Description

控制信息的发送，接收方法及装置、通信系统 技术领域
本公开涉及通信领域，具体而言，涉及一种控制信息的发送，接收方法及装置、通信系统。
背景技术
在相关技术的LTE-A(演进的LTE)中，采用中继(Relay)技术能够有效拓展网络覆盖，改善小区边缘数据速率，并且利用无线回传(backhaul)避免了有线传输网络的建设，能够快速部署，从而降低运营商的建设和运营成本。因此Relay技术是LTE-Adv接入节点ced系统采用的主要技术之一。在LTE-A的Relay技术中，对于帧结构设计，采用了基于fake MBSFN(多播/组播单频网络)subframe的时分半双工方案，即利用MBSFN子帧配置，配置一些fake MBSFN子帧来用于backhaul链路传输，而Access链路使用Non-MBSFN子帧，从而实现Backhaul链路与Access链路的时分双工，并且对终端来说是完全透明的。
在相关技术的5G或后续演进版本中，对Relay技术加以利用，例如在IAB(Integrated Access and Backhaul)技术中，会基于5G NR系统，进一步支持多跳Relay，并且网络拓扑支持冗余联接。基于此，链路质量可能会有明显提高，随着链路质量的提高，为系统使用更高阶的调制方式提供了可能性，从而能最大程度发挥Relay技术带来的系统性能提升。
在LTE技术中，对于控制信道和业务信道，调制方式的确定是有区别的，对于物理下行控制信道(PDCCH)，为了保证高可靠性，不支持调制方式的自适应选择，PDCCH只能使用QPSK(正交相移键控)来进行调制；而对于物理下行业务信道(PDSCH)，基站可以根据自己获得的信道质量信息，动态自适应确定调度给某个用户的PDSCH的调制方式，并在PDCCH DCI中通知给用户。因此，用户需要先接收PDCCH，基于PDCCH的指示才可以接收PDSCH，那么用户对于PDCCH的接收，要基于盲检测。基站会为用户配置若干个搜索空间，每个搜索空间包含多个PDCCH Candidates，支持不同聚合级别的PDCCH Candidates(候选位置)，聚合级别为N的PDCCH Candidate，意味着该PDCCH Candidate由4个CCE聚合而成。
在相关技术的5G标准中，还引入了带宽部分(Band Wide Part，BWP)的概念，基站可以为终端在一个载波上配置一个或多个BWP，并且使终端了解当前激活的BWP。
为了最大程度发挥Relay技术带来的系统性能提升，PDCCH的调制阶数，可能不再像LTE那样固定为QPSK，那么如何确定某条链路的PDCCH调制阶数，是需要解决的问题。
针对相关技术中存在的上述问题，目前尚未发现有效的解决方案。
