本公开涉及通信技术领域,特别是指一种数据信道传输带宽确定方法、装置、网络侧设备及终端。
背景技术
卫星通信系统中,为了降低峰值平均功率比PAPR,下行链路采用DFT-s-OFDM(离散傅里叶变换扩频的正交频分复用多址接入技术)波形。然而DFT-s-OFDM波形的生成需要连续的资源分配。网络侧在一个时隙slot内可能同时发送多个物理下行共享信道PDSCH。调度PDSCH的控制信令中只包含该PDSCH的频域资源分配信息,因此终端在接收时无法判断单载波波形基于多大带宽生成,从而造成接收失败。
具体的,因为在同一个slot内基站可以发送多个PDSCH,因此在生成波形时是基于多个PDSCH的传输带宽进行transform precoding(变换预编码)操作,所以,终端接收下行数据信道并对transform precoding进行逆向操作时,需要获知多个同时传输的PDSCH所占用的总带宽,而该信息无法从PDSCH对应的DCI(下行控制信息)中获取。
由上可知,卫星通信系统下行链路采用DFT-s-OFDM波形。当多个下行数据信道(即PDSCH)共存,且多个下行数据信道的频域资源连续或者不连续时,当前方案存在终端侧无法获知数据信道传输带宽从而导致数据接收失败的问题。

本公开实施例中,所述数据信道传输带宽为网络侧设备在同一时隙中同时发送的多个数据信道占用(传输)的总带宽。
下面结合网络侧设备和终端双方对本公开实施例提供的所述数据信道传输带宽确定方法进行进一步说明,网络侧设备以基站为例,调度信息以下行控制信息DCI为例。
针对上述技术问题,本公开实施例提供了一种数据信道传输带宽确定方法,主要涉及:在DCI中携带数据信道传输带宽指示信息;预定义DCI中数据信道传输带宽指示信息与数据信道传输带宽之间的对应关系(包括与数据信道传输带宽大小之间的对应关系,或者与数据信道传输带宽大小以及位置之间的对应关系);根据DCI中携带的数据信道传输带宽指示信息确定频域资源分配粒度。
具体的,其中,基站侧:
1、基站在调度数据信道传输的DCI中携带数据信道传输带宽指示信息;
具体的,所述数据信道传输带宽指示信息可包含N bit(N的值可根据要传输的信息实际确定),N为大于1的正整数。
其中,所述N bit可指示2 N种不同的状态信息,每种状态信息对应一种数据信道传输带宽大小,或者对应一种数据信道传输带宽大小及位置;
较优的,数据信道传输带宽指示信息的指示域应当位于频域资源指示域之前。
2、数据信道传输带宽的划分可通过预定义的方式确定:
方法1:预定义数据信道传输带宽的范围(即数据信道传输带宽大小,比 如全带宽、1/2带宽以及1/4带宽),并确定不同数据信道传输带宽范围下每个带宽范围包含的资源块RB编号(即预定义数据信道带宽范围与RB范围之间的对应关系,也就是数据信道传输带宽大小与数据信道传输带宽位置之间的对应关系),如下表1为支持的数据信道传输带宽大小为全带宽、1/2带宽以及1/4带宽的带宽划分(数据信道传输带宽指示信息与数据信道传输带宽大小和位置之间的对应关系,但并不以此为限),假设整个传输带宽所包含的RB数目为M(可根据系统带宽确定),终端确定数据信道传输带宽大小及其确切位置的过程可为:终端根据数据信道带宽指示信息,确定数据信道传输带宽的大小,即全带宽或1/2带宽或1/4带宽;终端根据频域资源分配指示信息确定其分配到的RB的RB index(即资源块索引,具体的可根据最低或最高RB index)所在的数据信道传输带宽RB范围,从而确定数据信道传输带宽的确切频域位置。
其中,在RB index跨子带(RB范围)时,可根据带宽大小与位置的对应关系进行映射操作,比如分配到的RB的RB index跨1/4带宽和2/4带宽的RB index,则可映射到1/2带宽;比如分配到的RB的RB index跨1/4带宽至3/4带宽的RB index,则可映射到全带宽;又比如分配到的RB的RB index跨2/4带宽至3/4带宽的RB index,则可映射到全带宽。

方法2:数据信道传输带宽大小以及其在传输带宽内的具体位置均由DCI中的数据信道传输带宽指示信息进行指示,所述数据信道传输带宽指示信息的指示域长度可为N bits,N为大于1的正整数。
假设数据传输带宽大小有三种,全带宽,1/2带宽,1/4带宽,N=2bits;数据信道传输带宽指示信息与数据信道传输带宽大小和位置之间的对应关系可如下表2(表中,M为整个传输带宽所包含的RB数目)所示,但并不以此为限:

假设数据传输带宽大小有三种,全带宽,1/2带宽,1/4带宽,N=3bits;数据信道传输带宽指示信息与数据信道传输带宽大小和位置之间的对应关系可如下表3(表中,M为整个传输带宽所包含的RB数目)所示,但并不以此为限:
表3

方法3:数据信道传输带宽指示信息指示数据信道传输带宽大小,所述数据信道传输带宽指示信息的指示域长度可为N bits,N为大于1的正整数。不同大小的数据传输信道带宽的频域具体位置可通过预定义的方式(比如子带位置固定)确定。所述预定义的方式可限定数据信道传输带宽大小与数据信道传输带宽位置之间的对应关系可为:数据信道传输带宽位置都是从最低的RB索引开始,全带宽范围为0~M-1;1/2带宽范围为
Figure PCTCN2020081675-appb-000006
或者
Figure PCTCN2020081675-appb-000007
1/4带宽范围为
Figure PCTCN2020081675-appb-000008
或者
Figure PCTCN2020081675-appb-000009
对应关系也可为:数据信道传输带宽位置都是从最高的RB索引开始,全带宽范围为0~M-1;1/2带宽范围为

或者

其中,M为整个传输带宽所包含的RB数目。
3、进一步的,频域资源分配粒度可根据DCI中的数据信道传输带宽指示信息进行调整;
例如,以如上假设为例,当数据信道传输带宽大小为1/4带宽时,资源分配粒度可为1个资源块RB;当数据信道传输带宽大小为1/2带宽时,资源分配粒度可为2个RB;当数据信道传输带宽大小为全带宽时,资源分配粒度可为4个RB,但并不以此为限。终端侧:
1、终端接收DCI并获得其中的数据信道带宽指示信息;
2、终端根据预定义的规则,结合DCI中的数据信道带宽指示信息,确定数据信道传输带宽大小及其具体位置;具体的,终端根据与基站相对应的预定义方式进行确定过程,可参见上述基站侧的预定义相关内容,在此不再赘 述。
3、进一步的,终端根据数据信道传输带宽指示信息,获得频域资源分配粒度(对应于基站侧的,频域资源分配粒度可根据DCI中指示的数据信道传输带宽进行调整)。
下面对本公开实施例提供的方案进行举例说明。
示例1(对应于上述方法1):假设系统带宽为400MHz,子载波间隔为120kHz,则系统带宽内包含250个RB。假设可能的数据传输带宽为全带宽,1/2带宽以及1/4带宽。假设网络侧在一个slot内同时调度了多个PDSCH。
网络侧在发送调度PDSCH的DCI内携带数据信道传输带宽指示信息。在此例中,由于可能的数据信道传输带宽有三种,因此需要的指示域大小为N=ceil(log 2(3))=2bits(ceil表示取整)。需要注意的是,该指示域需要放置在频域资源分配指示域之前。该2bits信息的不同状态指示不同的数据信道传输带宽大小,具体的信令解析可见如下表4:
表4
数据信道传输带宽指示信息 数据信道传输带宽大小
00 全带宽
01 1/2带宽
10 1/4带宽
11 Reserved
终端根据该指示信息,并根据如下方法确定所述连续频域资源(即数据信道传输带宽)在系统带宽内的具体位置:终端根据频域资源分配信息,确定网络侧为数据信道分配的RB的RB index,并根据该RB index,确定数据传输所在的子带范围(即数据信道传输带宽的确切频域位置)。所述子带范围通过如下表5进行预定义,例如如果UE#1的PDSCH所占用的RB的RB index为45~120且数据信道传输带宽指示信息所指示的数据信道传输带宽大小为1/2带宽,则UE#1可获知数据信道传输带宽为BW#0,且其子带范围为RB#0~RB#125。
表5
Figure PCTCN2020081675-appb-000015
其中,所述多个PDSCH的频域资源分配均不能大于DCI指示的数据信道传输带宽。
终端确定数据信道传输带宽大小和位置之后,便可以根据确定的数据信道传输带宽大小和位置对波形检测之后的数据进行IFFT(快速傅里叶反变换)变化,还原调制符号。
本方案亦可应用于更多的数据信道传输子带,例如最小的传输带宽为1/8系统带宽,则相应的数据信道传输带宽指示信息需要大小为3bits的指示域进行指示,在此不作限定的。
示例2:如示例1所述。终端在通过DCI中携带的数据信道传输带宽指示信息获知所述数据信道传输带宽大小之后,(1)可根据如下规则确定所述数据信道传输带宽在系统带宽内所处的频域位置(对应于上述方法2)。
所述DCI中携带的数据信道传输带宽指示信息用于指示数据信道传输带宽大小以及所述带宽的频域位置,所述数据信道传输带宽指示信息的指示域的长度为N bits。
当N=2bits时:所有预定义的数据信道传输带宽的起点可相同,例如均从RB#0开始。当数据信道传输带宽指示信息指示为全带宽时,所述带宽的频域位置为RB#0~249;当数据信道传输带宽指示信息指示为1/2带宽时,所述带宽的频域位置为RB#0~125;当数据信道带宽指示信息指示为1/4带宽时,所述带宽的频域位置为RB#0~63。具体的,所述方法可通过如下表6进行描述。
表6
  数据信道传输带宽 数据信道传输带宽位置
00 全带宽 0~249
01 1/2带宽 0~125
10 1/4带宽 0~63或者0~62
11 Reserved Reserved
当N=3bits时,可通过如下表7确定数据信道传输带宽大小及其频域位置:
表7
Figure PCTCN2020081675-appb-000016
(2)或者,DCI中的数据信道传输带宽指示信息仅用于指示数据信道传输带宽大小,而不同大小数据信道传输带宽的频域位置通过协议预定义的方式确定(对应于上述方法3)。例如所述对应关系为,全带宽范围为0~M-1;1/2带宽范围为
Figure PCTCN2020081675-appb-000017
或者
Figure PCTCN2020081675-appb-000018
1/4带宽范围为
Figure PCTCN2020081675-appb-000019
或者
Figure PCTCN2020081675-appb-000020
也即终端只要获得了数据信道传输带宽指示信息,便可进一步获知数据信道传输带宽在系统带宽内的资源位置。
本方案亦可应用于更多的数据信道传输子带,例如最小的传输带宽为1/8系统带宽,则相应的数据信道传输带宽指示信息至少需要大小为3bits的指示域进行指示,在此不作限定的。
示例3:如示例1和示例2,进一步的,基站侧和终端侧根据数据信道传 输带宽指示信息,确定频域资源分配所使用的资源粒度。例如,以如上假设为例,当数据信道传输带宽大小为1/4带宽时,资源分配粒度可为1个RB;当数据信道传输带宽大小为1/2带宽时,资源分配粒度可为2个RB;当数据信道传输带宽大小为全带宽时,资源分配粒度可为4个RB,但并不以此为限。
示例4:如示例1~3,其中示例1或者示例2或者两者之一与示例3的组合,可应用与下行数据调度,亦可应用于上行数据调度(比如在上行调度信令中携带数据信道传输带宽指示,具体可针对上行共享信道PUSCH)。
由上可知,本公开实施例提供的方案涉及:基站在DCI中携带数据信道传输带宽指示信息,并通过一定的规则确定数据信道传输带宽在系统带宽内的频域资源位置;对应的,终端接收调度信息(即DCI),并根据调度信息和基站侧对应的规则,确定数据信道传输带宽大小及位置;后续终端根据数据信道传输带宽大小及位置,可正确的接收基站发送的数据,完成信号处理过程。
