本申请主张在2018年4月13日在中国提交的中国专利申请号No.201810331798.6的优先权，其全部内容通过引用包含于此。
技术领域
本公开实施例涉及通信技术领域，具体涉及一种监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)的方法、用户设备和网络侧设备。
背景技术
目前，在长期演进(Long Term Evolution，LTE)和第五代移动通信(fifth-generation，5G)的新无线(New Radio，NR)技术中，用户设备(User Equipment，UE)通常会在每个时隙(slot)或者子帧上进行PDCCH盲检测。如果UE接收到属于该UE的PDCCH，那么该UE在该PDCCH指示的时频资源上接收下行数据或发送上行数据。如果UE没有接收到属于该UE的PDCCH，那么该UE在下一个slot或者子帧上或在符合基站配置的PDCCH监听周期和偏移量的slot或者子帧上继续进行PDCCH盲检测。
由于微信和网页浏览等很多流行的业务，其业务包到达时间存在随机性或不均匀性，实际网络中，当UE处于激活态并持续监听PDCCH时，并不是slot或者子帧上都能收到调度该UE的PDCCH。对于没有调度该UE的PDCCH的slot或者子帧，该UE在这些slot或者子帧盲检测PDCCH的行为会导致UE电量的消耗。
在NR技术中，高层信令可以通过参数：上行-下行-配置-公共(UL-DL-configuration-common)，上行-下行-配置-公共-集合2(UL-DL-configuration-common-Set2)或上行-下行-配置-专用(UL-DL-configuration-dedicated)来配置UE的时隙格式(slot format)。然而，高层信令配置的时隙格式无法快速的适配业务包到达时间存在随机性或不均 匀性的业务。
后续演进通信系统也依然可能存在上述问题。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。
在本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设 计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面结合附图介绍本公开的实施例。本公开实施例提供的配置物理下行控制信道的方法、用户设备和网络侧设备可以应用于无线通信系统中。该无线通信系统可以为采用5G系统，或者演进型长期演进(Evolved Long Term Evolution，eLTE)系统，或者后续演进通信系统。参考图1，为本公开实施例提供的一种无线通信系统的架构示意图。如图1所示，该无线通信系统可以包括：网络侧设备10和用户设备，例如用户设备记做UE11，UE11可以与网络侧设备10。在实际应用中上述各个设备之间的连接可以为无线连接，为了方便直观地表示各个设备之间的连接关系，图1中采用实线示意。
需要说明的是，上述通信系统可以包括多个UE，网络侧设备和可以与多个UE通信(传输信令或传输数据)。
本公开实施例提供的网络侧设备10可以为基站，该基站可以为通常所用的基站，也可以为演进型基站(evolved node base station，eNB)，还可以为5G系统中的网络侧设备(例如下一代基站(next generation node base station，gNB)或发送和接收点(transmission and reception point，TRP))或者小区cell等设备。
本公开实施例提供的用户设备可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本或者个人数字助理(Personal Digital Assistant，PDA)等。
需要说明的是，本文中的时隙可以为普通时隙，例如：普通时隙由14个时域符号组成，或该时隙还可以为微时隙(Mini Slot)，微时隙由小于14个时域符号组成，例如2、4或7个时域符号组成一个微时隙。
当然，本文中的时隙还可以是传输时间间隔(Transmission Time Interval，TTI)、子帧(subframe)、时域调度粒度等。
参见图2，图中示出根据本公开实施例的一种配置时隙格式指示(Slot Format Indicator，SFI)的方法的流程，该方法的执行主体为UE，具体步骤如下：
步骤201：从网络侧接收物理层信令或媒体接入控制(Media Access Control，MAC)层信令，该物理层信令或MAC层信令指示该UE或包括该UE在内的多个UE的SFI；
具体地，在步骤201中，接收具有第一下行控制信息(Downlink Control Information，DCI)格式的PDCCH上的物理层信令。
在本公开实施例中，可选地，第一DCI格式的PDCCH的循环冗余校验(Cyclic Redundancy Check，CRC)通过UE专用无线网络临时标识(Radio Network Temporary Identity，RNTI)进行加扰，例如：小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)或者临时的小区无线网络临时标识(Temporary Cell-Radio Network Temporary Identifier，TC-RNTI)；
在本公开实施例中，可选地，所述第一DCI格式的PDCCH的CRC通过对应多个UE的RNTI进行加扰，例如：时隙格式指示符-无线网络临时标识(SFI-RNTI)或其他RNTI。
在本公开实施例中，可选地，第一DCI格式的比特包括：第一DCI格式的标识符；以及一个或多个时隙格式指示符，一个或多个时隙格式指示符对应于该UE在后续N个时隙上的时隙格式，或者对应于包括所述UE在内的多个UE在后续N个时隙上的时隙格式，其中，N大于或等于1。
例如：多个时隙格式指示符对应于该UE在后续N个时隙上的时隙格式时，该多个时隙格式指示符包括：时隙格式指示符1(Slot Format Indicator 1)、时隙格式指示符2、……、时隙格式指示符N，N代表N个时隙。
又例如：多个时隙格式指示符对应于包括该UE在内的多个UE在后续N个时隙上的时隙格式时，该多个时隙格式指示符包括：第一UE的时隙格式指示符1、第一UE的时隙格式指示符2、……、第一UE的时隙格式指示符N，第二UE的时隙格式指示符1、第二UE的时隙格式指示符2、……、第二UE的时隙格式指示符N，以此类推，其中N代表N个时隙。
在本公开实施例中，可选地，第一DCI格式的比特可以重用已有DCI格式的比特，例如利用已有DCI格式中的填零(padding)比特，或者改变已有DCI格式中的部分比特用作第一DCI格式的比特。
步骤202：根据物理层信令或MAC层信令确定该UE的SFI。
具体地，当SFI指示的时域符号为上行符号和/或灵活符号时，UE不在SFI指示的时域符号上监听PDCCH；其中，该灵活符号可以配置为上行符号或下行符号的符号。
在本公开实施例中，可选地，SFI指示出一个或多个UE在后续N个时隙上的时隙格式(Slot Format，SF)，N大于或等于1，如N为10个slot，20个slot或者40个slot。其中，N由网络侧通过无线资源控制(Radio Resource Control，RRC)信令配置。进一步地，不同的UE的SF可以不同。
在本公开实施例中，可选地，接收所述物理层信令或MAC层信令的第一时隙和所述SFI生效的第二时隙之间存在第一间隔。
进一步地，第一间隔为协议预定义的零个时隙，或者所述第一间隔为协议预定义的固定个数时隙，或者所述第一间隔的长度由网络侧配置，例如通过RRC信令配置。
虽然NR技术也支持通过物理层信令如DCI format 2_0来配置一组UE的SFI，但是，DCI format 2_0配置的多个UE的时隙格式都是相同的，无法满足不同UE由于各自业务不同带来的多样化的监听PDCCH行为的需求。另外，DCI format 2_0可以通过配置多个UE的时隙格式来间接的避免UE监听不必要的PDCCH，但只能更改高层信令配置的时隙格式中的灵活符号(不能更改上行符号或者下行符号)，效率比较低。
这样，通过物理层信令或者MAC层信令配置一个或多个UE的SFI，进而通过物理层信令或者MAC层信令快速的适配业务包到达时间存在随机性或不均匀性的业务。
参见图3，图中示出根据本公开实施例的一种配置时隙格式指示的方法流程，该方法的执行主体为网络侧设备，具体步骤如下：
步骤301：向一个或多个UE发送物理层信令或MAC层信令，所述物理层信令或MAC层信令指示所述一个或多个UE的SFI。
具体地，在步骤301中，在具有第一DCI格式的PDCCH上向一个或多个UE发送物理层信令。
在本公开实施例中，可选地，第一DCI格式的PDCCH的CRC通过UE专用RNTI进行加扰，例如：C-RNTI或者TC-RNTI；
在本公开实施例中，可选地，所述第一DCI格式的PDCCH的CRC通过对应多个UE的RNTI进行加扰，例如：SFI-RNTI或其他RNTI。在本公开实施例中，可选地，第一DCI格式的DCI的比特包括：第一DCI格式的标识符；以及一个或多个时隙格式指示符，该一个或多个时隙格式指示符对应于一个UE在后续N个时隙上的时隙格式，或者对应于多个UE在后续N个时隙上的时隙格式；其中，N大于或等于1。
例如：多个时隙格式指示符对应于一个UE在后续N个时隙上的时隙格式时，该多个时隙格式指示符包括：时隙格式指示符1(Slot Format Indicator 1)、时隙格式指示符2、……、时隙格式指示符N，N代表N个时隙。
又例如：多个时隙格式指示符对应于多个UE在后续N个时隙上的时隙格式时，该多个时隙格式指示符包括：第一UE的时隙格式指示符1、第一UE的时隙格式指示符2、……、第一UE的时隙格式指示符N，第二UE的时隙格式指示符1、第二UE的时隙格式指示符2、……、第二UE的时隙格式指示符N，以此类推，其中N代表N个时隙。
在本公开实施例中，可选地，SFI指示出一个或多个UE在后续N个时隙上的时隙格式(Slot Format，SF)，N大于或等于1，如N为10个slot，20个slot或者40个slot，N由网络侧通过RRC信令配置。进一步地，不同的UE的SF可以不同。
在本公开实施例中，可选地，第一DCI格式的比特可以重用已有DCI格式的比特，例如利用已有DCI格式中的填零padding比特，或者改变已有DCI格式中的部分比特用作第一DCI格式的比特。
在本公开实施例中，可选地，当SFI指示的时域符号为上行符号和/或灵活符号时，所述UE不在所述SFI指示的所述时域符号上监听PDCCH；其中，所述灵活符号可以配置为上行符号或下行符号的符号。
这样，通过物理层信令或者MAC层信令配置一个或多个UE的SFI，进而通过物理层信令或者MAC层信令快速的适配业务包到达时间存在随机性或不均匀性的业务。

在本公开实施例中，可选地，第二DCI格式的PDCCH的CRC通过UE专用RNTI进行加扰，例如：C-RNTI或者TC-RNTI；
在本公开实施例中，可选地，第二DCI格式的PDCCH的CRC通过对应多个UE的RNTI进行加扰，例如：SFI-RNTI或其他RNTI。
