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。
本公开实施例提供一种LBT子带划分方法、装置、设备及介质。下面首先对本公开实施例提供的LBT子带划分方法进行说明。
图1示出了本公开实施例提供的LBT子带划分方法的流程示意图。LBT子带划分方法可以包括:
S101:获取第一信息,其中,第一信息包括目标的频域起止位置信息,目标包括载波或BWP。可以理解的是,频域起止位置信息包括频域起始位置信息和频域终止位置信息。
S102:根据频域起止位置信息,将目标划分为LBT子带。
对于载波,可以从系统信息块(System Information Block,SIB)1中获取载波的频域起止位置信息。
对于BWP,在接收到无线资源控制(Radio Resource Control,RRC)消息(比如配置Setup消息、恢复Resume信息和重建Reestablishment消息等)之前的BWP,其频域起止位置信息与控制资源集(Control resource set,CORESET)#0的频域起止位置信息相同;在接收到RRC消息之后的BWP,其频域起止位置信息由SIB1中的信息配置;对于终端设备专用的BWP,可以根据该BWP的子载波间隔(Subcarrier spacing,SCS)配置和SIB1中的载波信息配置得到该BWP所属的参考带宽范围,在该参考带宽范围内通过位置和带宽(locationAndBandwidth)指示的资源指示值(Resource indicator value,RIV)得到该BWP的频域起止位置信息。
本公开实施例的LBT子带划分方法可以应用于网络侧设备,也可以应用于终端设备。本公开的网络侧设备可以为基站,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)或者后续演进通信系统中的网络侧设备。然而,上述用词 并不构成对本公开保护范围的限制。终端设备的示例包括但不限于手机、平板电脑、笔记本电脑、掌上电脑、车载终端、可穿戴设备、以及计步器等。
在本公开的一个实施例中,第一信息还可以包括:LBT信道规划信息。其中,不同的LBT信道带宽可以对应不同的LBT信道规划信息。不同的位置(比如国家或地区)也可以对应不同的LBT信道规划信息。比如,中国的LBT信道规划信息为在5170兆赫兹(MHz)至5330MHz这个频率范围上从5170MHz开始每20MHz作为一个LBT信道;美国的LBT信道规划信息为在5170MHz至5330MHz这个频率范围上从5170MHz开始每40MHz作为一个LBT信道。
当划分目标的LBT子带时,可以根据频域起止位置信息和LBT信道规划信息,将目标划分为LBT子带。在一些实施例中,可以根据频域起止位置信息和LBT信道规划信息,将目标划分为L个LBT子带。
示例性的,假设LBT信道规划信息为在5170MHz至5330MHz这个频率范围上从5170MHz开始每20MHz作为一个LBT信道。目标的频域起始位置为5210MHz,目标的频域终止位置为5290MHz。可以将目标划分为4个LBT子带。LBT子带划分结果如图2所示。图2示出了本公开的LBT子带划分结果的第一种示例的示意图。
在本公开的一个实施例中,第一信息还可以包括:LBT子带划分粒度。当划分目标的LBT子带时,可以从目标的频域起始位置开始,按照LBT子带划分粒度,将目标划分为M个LBT子带。
示例性的,假设LBT子带划分粒度为40MHz,目标的频域起始位置为5210MHz,目标的频域终止位置为5290MHz。
从目标的频域起始位置5210MHz开始,每40MHz划分为一个LBT子带。LBT子带划分结果如图3所示。图3示出了本公开的LBT子带划分结果的第二种示例的示意图。
在本公开的一个实施例中,第一信息还可以包括:LBT子带划分粒度和划分起始位置信息。当划分目标的LBT子带时,可以将目标的频域起始位置至划分起始位置,划分为一个LBT子带;从划分起始位置开始,按照 LBT子带划分粒度,将目标划分为N个LBT子带。
示例性的,假设LBT子带划分粒度为20MHz,目标的频域起始位置为5210MHz,目标的频域终止位置为5290MHz。划分起始位置为5240MHz。
将目标的频域起始位置5210MHz至5240MHz划分为目标的一个LBT子带;从5240MHz开始,每20MHz划分为一个LBT子带,即将5240MHz至5260MHz划分为一个LBT子带,将5260MHz至5280MHz划分为一个LBT子带,将5280MHz至5290MHz划分为一个LBT子带。LBT子带划分结果如图4所示。图4示出了本公开的LBT子带划分结果的第三种示例的示意图。
在本公开的一个实施例中,第一信息还包括:频域分割位置信息。当划分目标的LBT子带时,可以从目标的频域起始位置开始,基于频域分割位置,将目标划分为P个LBT子带。
示例性的,假设目标的频域起始位置为Fstart,目标的频域终止位置为Fend。频域分割位置信息包括5个频域分割点,5个频域分割点分别为F1、F2、F3、F4和F5,5个频域分割点对应的频率依次增加。则将目标划分为6个LBT子带,6个LBT子带的频率范围分别为Fstart至F1、F1至F2、F2至F3、F3至F4、F4至F5和F5至Fend。LBT子带划分结果如图5所示。图5示出了本公开的LBT子带划分结果的第四种示例的示意图。
在本公开的一个实施例中,第一信息还可以包括:每个LBT子带的起始物理资源块(Physical Resource Block,PRB)信息和终止PRB信息。当划分目标的LBT子带时,可以根据频域起止位置信息、起始PRB信息和终止PRB信息,将目标划分为Q个LBT子带。
其中,PRB信息可以包括PRB索引或PRB偏移。
在本公开的一个实施例中,当目标为载波时,第一信息还可以包括:BWP的频域起止位置信息。
当划分BWP的LBT子带时,可以确定BWP的频域起始位置位于载波的LBT子带的第一位置;确定BWP的频域终止位置位于载波的LBT子 带的第二位置;根据第一位置和第二位置,将BWP划分为R个LBT子带。
示例性的,假设确定出BWP的频域起始位置位于载波的第i个LBT子带,确定出BWP的频域终止位置位于载波的第j个LBT子带,则将BWP划分为j-i+1个LBT子带。LBT子带划分结果如图6所示。图6示出了本公开的LBT子带划分结果的第五种示例的示意图。
本公开实施例的LBT子带划分方法,能够根据载波的频域起止位置信息或BWP的频域起止位置信息,将目标划分为LBT子带。
在本公开的一个实施例中,还可以按照频率位置对LBT子带进行编号。
示例性的,对于LBT子带频率范围分别为Fstart至F1、F1至F2、F2至F3、F3至F4、F4至F5和F5至Fend的六个LBT子带。
将LBT子带频率范围为Fstart至F1的LBT子带编号为#0;将LBT子带频率范围为F1至F2的LBT子带编号为#1;将LBT子带频率范围为F2至F3的LBT子带编号为#2;将LBT子带频率范围为F3至F4的LBT子带编号为#3;将LBT子带频率范围为F4至F5的LBT子带编号为#4;将LBT子带频率范围为F5至Fend的LBT子带编号为#5。
在本公开的一个实施例中,网络侧设备还可以配置第二信息,其中,第二信息包括LBT子带指示域,LBT子带指示域用于指示使用的LBT子带为基于预定义的LBT子带划分方式所划分出的LBT子带。
其中,基于预定义的LBT子带划分方式包括:上述的根据频域起止位置信息和LBT信道规划信息,将目标划分为L个LBT子带的划分方式;上述的从目标的频域起始位置开始,按照LBT子带划分粒度,将目标划分为M个LBT子带的划分方式;上述的将目标的频域起始位置至划分起始位置,划分为一个LBT子带;从划分起始位置开始,按照LBT子带划分粒度,将目标划分为N个LBT子带的划分方式;上述的从目标的频域起始位置开始,基于频域分割位置,将目标划分为P个LBT子带的划分方式;或上述的根据频域起止位置信息、起始PRB信息和终止PRB信息,将目标划分为Q个LBT子带的划分方式。
划分目标LBT子带的方式即为基于目标的LBT子带划分方式。可以理解的是,基于载波的LBT子带划分方式指划分载波LBT子带的方式,基于BWP的LBT子带划分方式指划分BWP LBT子带的方式。
示例性的,LBT子带指示域指示使用的LBT子带为基于载波的LBT子带划分方式所划分出的LBT子带中的第4个子带。该基于载波的LBT子带划分方式划分出的LBT子带有6个。6个LBT子带分别为:编号为#0的频率范围为Fstart至F1的LBT子带,编号为#1的频率范围为F1至F2的LBT子带;编号为#2的频率范围为F2至F3的LBT子带;编号为#3频率范围为F3至F4的LBT子带;编号为#4的频率范围为F4至F5的LBT子带;编号为#5的频率范围为F5至Fend的LBT子带。LBT子带指示域指示所使用的LBT子带为编号为#3频率范围为F3至F4的LBT子带。
