本申请主张在2017年10月19日在中国提交的中国专利申请号No.201710975853.0的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,特别涉及一种控制信息的发送方法、检测方法、网络设备及终端。
背景技术
相关技术中的移动通信系统中,控制信道需要占用整个系统带宽,如图1所示。用户在检测控制信道以获取控制信息时,需要对整个系统带宽进行检测。这样主要引起:1)终端需要检测整个系统带宽,如果带宽较大,终端检测控制信息的复杂度会急剧上升;2)终端需要匹配的大带宽,用于接收控制信息,这样不利于终端带宽灵活配置,及小带宽终端的接入。
为了解决上述问题,根据标准化进展,一种方法是将N个可用OFDM符号内的控制信道可用带宽划分为M个控制子带或控制资源集合(Control Resource Set),这样终端只需要在一个控制资源集合对控制信息里面进行检测,可以有效地降低终端检测复杂度,如图2所示。
相关技术中的方案中,控制资源集合一般映射到一个时隙的最前面的1、2或3个符号上。
5G系统采用多波束设计,以提升覆盖性能。一个同步周期内,多个同步块(SS/PBCH block)用于用户同步,每个同步块对应一个波束。这里定义“用于某些公共系统信息(与LTE系统中的系统信息块SIB类似)发送的控制资源集合为公共控制资源集合”,公共控制资源集合需要优化设计,以提升系统信息发送的传输可靠性。
相关技术中的传输的方法是,公共控制资源集合放置在一个时隙的前几个符号内,与同步块时分复用。
这种方法,在多波束系统设计的场景下,每个公共控制资源集合都需要波束扫描,由于该波束方向是固定的,所以只能调度该波束范围内的用户,如果波束的个数较多,会大大降低系统调度的灵活性。
发明内容
本公开提供了一种控制信息的发送方法、检测方法、网络设备及终端。通过将控制资源集合映射到与同步块占用的多个符号的相同时域资源上,可以降低波形扫描占用的时频资源,以提升用户调度的灵活度,并降低终端检测的复杂度。
