Description

一种控制信道的资源确定方法及装置、计算机存储介质 技术领域
本发明涉及无线通信技术领域，尤其涉及一种控制信道的资源确定方法及装置、计算机存储介质。
背景技术
在第五代(5G，5 th Generation)新无线(NR，New Radio)系统中，对于初始接入的用户设备(UE，User Equipment)，需要定义一个公共搜索空间(Common Search Space)用于接收公共控制信息，例如剩余最小系统信息(RMSI，Remaining Minimum System Information)。为此，引入了控制资源集(CORESET，Control Resource Set)的概念，CORESET定义为用于承载控制信息的资源集合，UE在该资源集合中检测物理下行控制信道(PDCCH，Physical Downlink Control Channel)，以获得承载RMSI的物理下行共享信道(PDSCH，Physical Downlink Shared Channel)的调度信息。CORESET的资源配置信息承载在同步信号块(SSB，Synchronization Signal Block)的物理广播信道(PBCH，Physical Broadcast Channel)中，用于UE接收RMSI。
在CORESET的资源配置信息中，包括PDCCH所在的频域位置，还有PDCCH的监听窗口(monitoring window)。PDCCH的监听窗口通过以下方式确定：对于SSB和CORESET的复用方式为pattern 1，则UE在两个连续的时隙监听Type0-PDCCH公共搜索空间。两个连续的时隙中起始时隙的编号为n 0。每个编号为i的SSB对应一个监听窗口，该监听窗口的起始时隙的编号n 0通过以下公式确定：
Figure PCTCN2018076865-appb-000001
其中，
Figure PCTCN2018076865-appb-000002
为一个无线帧中的时隙的个数。M和O通过PBCH中的CORESET的资源配置信息指示，O的取值在6GHz以下频域时包括{0,2,5,7}，在6GHz以上频域时包括{0,2.5,5,7.5}。M的取值包括{1/2,1,2}。μ的取值与PDCCH的子载波间隔有关，μ∈{0,1,2,3}。
上述方案中，
Figure PCTCN2018076865-appb-000003
计算得到的结果可以包括
Figure PCTCN2018076865-appb-000004
因此根据
Figure PCTCN2018076865-appb-000005
计算能得到的n 0可以为10ms无线帧中的任何一个时隙。在NR系统中，一个无线帧中的时隙可以配置成下行时隙或者上行时隙，如果计算得到的n 0分散在无线帧的各个时隙，则会造成这些时 隙必须配置成下行时隙，用于RMSI的发送，因此可以配置成上行时隙的资源就变少了，造成上行资源的不足。

具体实施方式
为便于理解本发明实施例的技术方案，以下对本发明实施例相关的技术进行说明。
1)5G中的波束发送
在5G系统中，由于采用的频段相比LTE更高，无线信号传输的路径损耗变大，无线信号的覆盖变小。此时，通过基站的多天线系统，采用波束赋形(beamforming)技术形成波束来提高无线信号的增益来弥补路径损耗是一种可行的方法。波束具有方向性，一个窄波束只能覆盖小区的部分区域，无法覆盖小区中的所有用户。如图1所示，基站可以通过4个不同方向的波束发送信号，对于波束B2，只能覆盖UE1，UE2无法覆盖；对于波束B4，只能覆盖UE2，UE1无法覆盖。
5G NR系统中的公共信道和信号，如同步信号和广播信道，需要通过多波束扫描的方式覆盖整个小区，便于小区内的UE接收。同步信号(SS，Synchronization Signal)的多波束发送时通过定义SS突发集(SS burst set)实现的。一个SS burst set包含一个或者多个SS burst，一个SS burst包含一 个或多个SSB。一个SSB用于承载一个波束的同步信号和广播信道。因此，一个SS burst set可以包含小区内SSB数目个波束的同步信号。如图2所示，一个SSB中包含一个符号的主同步信号(PSS，Primary Synchronization Signal)，一个符号的辅同步信号(SSS，Secondary Synchronization Signal)和两个符号的PBCH。
SS burst set的周期可配置，并且一个周期内发送的SS burst set承载在5ms的时间窗内发送。以15kHz子载波间隔为例，一个时隙(slot)包含14个符号(symbol)，可以承载两个SS block。在SSB中承载有该SSB编号的信息，UE通过该信息识别收到的SSB对应的编号。SS block的数目L根据系统的频段来确定：
3GHz以下的频段：L＝4；
3GHz至6GHz的频段：L＝8；
6GHz至52.6GHz的频段：L＝64。
除了同步信号和PBCH需要进行多波束扫描，其他的一些公共信息，如RMSI，寻呼(paging)，也需要通过多波束扫描的方式发送。
2)确定RMSI PDCCH的监听窗口
在RMSI CORESET的资源配置信息中，包括PDCCH所在的频域位置，还有PDCCH的监听窗口(monitoring window)。RMSI PDCCH的监听窗口通过以下方式确定：对于SSB和CORESET的复用方式为pattern 1，则UE在两个连续的时隙监听Type0-PDCCH公共搜索空间。两个连续的时隙中起始时隙的编号为n 0。每个编号为i的SSB对应一个监听窗口，该监听窗口的起始时隙的编号n 0通过以下公式确定：
Figure PCTCN2018076865-appb-000037
其中，
Figure PCTCN2018076865-appb-000038
为一个无线帧中的时隙的个数。M和O通过PBCH中的CORESET的资源配置信息指示，O的取值在6GHz以下频域时包括{0,2,5,7}，在6GHz以上频域时包括{0,2.5,5,7.5}。M的取值包括{1/2,1,2}。如下表1和表2所示，其中，表1为在SSB和CORESET的复用方式为pattern 1且频段范围1的情况下，Type0-PDCCH公共搜索空间的PDCCH监听窗口的参数，表2为在SSB和CORESET的复用方式为pattern 1且频段范围2的情况下，Type0-PDCCH公共搜索空间的PDCCH监听窗口的参数。
Figure PCTCN2018076865-appb-000039
表1
Figure PCTCN2018076865-appb-000040
表2
μ的取值与PDCCH的子载波间隔有关，根据下表3确定：
μ Δf＝2 μ·15[kHz] Cyclic prefix
0 15 Normal
1 30 Normal
2 60 Normal,Extended
3 120 Normal
4 240 Normal
表3
在确定时隙编号n 0之后，还要进一步确定监听窗口的起始时隙所在的无线帧编号SFN C：
如果
Figure PCTCN2018076865-appb-000041
则SFN C mod 2＝0；
如果
Figure PCTCN2018076865-appb-000042
则SFN C mod 2＝1。
即根据
Figure PCTCN2018076865-appb-000043
计算得到的时隙个数小于一个无线帧包含的时隙个数时，SFN C为偶数无线帧，当大于一个一个无线帧包含的时隙个数时，SFN C为奇数无线帧。
