Description
本公开涉及无线通信领域但不限于无线通信领域,尤其涉及一种数据传输处理方法、装置、通信设备及存储介质。
在新无线(New Radio,NR)技术中,当通信频段位于频率范围(Frequency Range,FR)2时,该FR2为高频段;由于高频信道衰减较快,为了保证覆盖范围等,通常需要基于波束(beam)进行数据传输。
然而,由于目前对于探测参考信号(Sounding Reference Signal,SRS)资源上只配置了一个发送波束的波束方向。当用户设备(User Equipement,UE)有多个天线面板(panel)或者传输接收点(Transmission Reception Point,TRP)时,那如何配置UE使用多个天线面板或TRP发送SRS,以提高SRS的传输效率,是波束方向亟需解决的问题。
发明内容
本公开实施例公开了一种数据传输处理方法、装置、通信设备及存储介质。
根据本公开实施例的第一方面,提供一种数据传输处理方法,应用于用户设备(UE),所述方法包括:
接收基站发送的配置信息,其中,所述配置信息中携带探测参考信号(SRS)资源配置信息;其中,针对一个所述SRS资源,所述配置信息用于指示L个目标波束信息,所述L为大于1的正整数;
基于L个所述目标波束信息指示的波束方向,发送所述SRS。
根据本公开实施例的第二方面,提供一种数据传输处理方法,应用于基站,所述方法包括:
向用户设备(UE)发送配置信息,其中,所述配置信息中携带探测参考信号(SRS)资源配置信息;其中,针对一个所述SRS资源,所述配置信息用于指示L个目标波束信息,所述L为大于1的正整数;
接收所述UE基于L个所述目标波束信息指示的波束方向发送的所述SRS。
根据本公开实施例的第三方面,提供一种数据传输处理方法,应用于用户设备(UE),包括:
第一接收模块,被配置为接收基站发送的配置信息,其中,所述配置信息中携带探测参考信号(SRS)资源配置信息;其中,针对一个所述SRS资源,所述配置信息用于指示L个目标波束信息,所述L为大于1的正整数;
第一发送模块,被配置为基于L个所述目标波束信息指示的波束方向,发送所述SRS。
根据本公开实施例的第四方面,提供一种数据传输处理装置,应用于基站,包括:
第二发送模块,被配置为向用户设备(UE)发送配置信息,其中,所述配置信息中携带探测参考信号(SRS)资源配置信息;其中,针对一个所述SRS资源,所述配置信息用于指示L个目标波束信息,所述L为大于1的正整数;
第二接收模块,被配置为接收所述UE基于L个所述目标波束信息指示的波束方向发送的所述SRS。
根据本公开实施例的第五方面,提供一种通信设备,所述通信设备,包括:
处理器;
用于存储所述处理器可执行指令的存储器;
其中,所述处理器被配置为:用于运行所述可执行指令时,实现本本公开任意实施例所述的数据传输处理方法。
根据本公开实施例的第六方面,提供一种计算机存储介质,其中,所述计算机存储介质存储有计算机可执行程序,所述可执行程序被处理器执行时实现本公开任意实施例所述的数据传输处理方法。
本公开实施例通过用户设备接收基站发送的配置信息,其中,所述配置信息中携带探测参考信号SRS资源配置信息,其中,针对一个所述SRS资源,所述配置信息用于指示L个目标波束信息,所述L为大于1的正整数;基于L个所述目标波束信息指示的波束方向,发送所述SRS。
如此,本公开实施例可以通过UE接收一次配置信息,就能利用配置信息中L个目标波束信息所指示的波束方向发送SRS,能够减少波束的配置信息,从而节省***资源。
并且,由于本公开实施例可以在一个SRS的资源上,使用L个目标波束信息所指示的波束方向发送SRS,增大了一个SRS的资源上传输的空间增益,从而提高了SRS传输效率。

如图2所示,提供一种数据传输处理方法,应用于用户设备(UE),所述方法包括:
步骤S21:接收基站发送的配置信息,其中,所述配置信息中携带SRS资源配置信息;其中,针对一个所述SRS资源,所述配置信息用于指示L个目标波束信息,所述L为大于1的正整数;

这里,所述配置信息包括一条或多条配置信令。

又如,在另一应用场景中,所述配置信息包括:一条RRC信令以及一条媒体接入控制(MAC)信令。该RRC信令用于针对一个SRS资源配置有M个波束信息,该MAC信令用于激活指示该M个波束信息中的L个目标波束信息。这里,所述L小于所述M。
这里,所述目标波束信息,包括但不限于以下之一:
空间关系信息;
传输配置指示(TCI)。
此处的TCI包括上行TCI。
此处的空间关系信息及上行TCI用于上行传输中,对参考信号标识的指示。
在一些实施例中,每个所述目标波束信息,用于指示一个参考信号标识对应的波束方向。
这里,一个所述目标波束信息,用于指示一个参考信号标识;一个所述参考标识信号,用于指示一个波束方向。
例如,一个所述空间关系信息,用于指示一个参考信号标识对应的波束方向。又如,一个所述上行TCI,用于指示一个参考信号标识对应的所述波束方向。这里用于指示的是SRS的上行发送波束方向,当参考信号下行参考信号比如NZP CSI-RS或SSB时,表示SRS的发送波束方向与终端接收该NZP CSI-RS或SSB时最好的接收波束方向相对应;当参考信号为上行参考信号比如SRS时,表示SRS的发送波束方向与终端发送该SRS时的发送方向一样。
这里,L个所述目标波束信息指示的波束方向为:L个所述目标波束信息指示的L个参考信号标识对应的波束方向。此处的L个目标波束信息,用于指示L个波束方向。
这里,所述参考信号包括但不限于以下之一:
非零功率信息状态参考信号(NZP CSI-RS);
同步信号块(SSB);
探测参考信号(SRS)。
这里,所述SRS包括但不限于以下至少之一:
用于信道状态测量的SRS;
用于波束测量的SRS;
用于天线切换的SRS;
用于定位的SRS。
如此,本公开实施例,可以基于L个目标波束信息所指示的不同波束方向,发送用于信道状态测量、用于波束测量、用于天线切换和/或用于定位的SRS。
在本公开实施例中,本公开实施例可以通过UE接收一次配置信息,就能利用配置信息中L个目标波束信息所指示的波束方向发送SRS,能够减少波束的配置信息,从而节省***资源。
并且,由于本公开实施例可以在一个SRS的资源上,使用L个,即使用多个目标波束信息所指示的波束方向发送SRS,增大了一个SRS的资源上传输的空间增益,从而提高了SRS的传输效率及传输成功率。
在一些实施例中,所述配置信息包含无线资源控制(RRC)信令,其中,所述RRC信令针对一个所述SRS资源指示L个所述目标波束信息。
在一实施例中,L个所述目标波束信息由一个波束信息指示域指示。
这里,所述波束信息指示域可以为携带在RRC中的指示域,所述波束信息指示域可以为空间关系信息(spatialrelationinfo)指示域或传输配置(TCI)指示域。所述波束信息指示域至少占一个比特。
例如,所述RRC信令的至少一个比特携带波束信息指示域;所述波束信息指示域指示有L个所述目标波束信息。
在一实施例中,所述波束信息指示域,用于指示L个空间关系信息;其中,一个所述空间关系信息,用于指示一个参考信号标识对应的波束方向。
在另一实施例中,所述波束信息指示域,用于指示L个TCI;其中, 一个所述TCI,用于指示一个参考信号标识对应的波束方向。
在本公开实施例中,若通过RRC信令直接指示L个所述目标波束信息,没有其它信令,例如没有MAC信令或DCI信令等来做进一步指示,则UE可以直接使用L个所述目标波束信息所指示的波束方向来发送所述SRS;如此,一方面,能够增大在一个SRS的资源上传输的空间增益,从而提高SRS的传输效率;另一方面还能进一步减少其它信令的开销等。
在另一些实施例中,所述配置信息包含RRC信令和MAC信令,其中,所述RRC信令针对一个所述SRS资源配置有M个波束信息,所述MAC信令激活指示M个所述波束信息中的L个所述目标波束信息;其中,所述M为正整数,所述L小于所述M。
在一实施例中,L个所述目标波束信息由一个波束信息指示域指示。
这里,所述波束信息指示域可以携带在MAC信令中。该MAC信令由基站生成。
例如,所述MAC信令的至少一个比特携带波束信息指示域,所述波束信息指示域可以为空间关系信息指示域或传输配置指示域;所述波束信息指示域指示有L个所述目标波束信息。
在本公开实施例中,在配置信息中,先通过RRC信令配置有M个波束信息,再通过MAC信令激活M个所述波束信息中的L个所述目标波束信息。
如此,本公开实施例不仅提供了另一种选取L个目标波束信息,并基于该L个目标波束信息所指示的波束方向发送SRS的方法。并且,还能不必选取一个SRS资源配置的M个波束信息中所有的波束信息,可通过MAC信令选择其中部分更加合适的目标波束信息所指示的波束方向进行SRS的发送,从而能够进一步提高SRS的传输效率。
在又一些实施例中,所述配置信息包含RRC信令和下行控制指示DCI 信令,其中,所述RRC信令针对一个所述SRS资源配置有M个波束信息,所述DCI信令指示M个所述波束信息中的L个所述目标波束信息;其中,所述M为正整数,所述L小于所述M。
在一实施例中,L个所述目标波束信息由一个波束信息指示域指示。
这里,所述波束指示域可以携带在所述DCI信令中。
例如,所述DCI信令的至少一个比特携带所述波束信息指示域,所述波束信息指示域可以为空间关系信息指示域或传输配置指示域;所述波束信息指示域指示有L个所述目标波束信息。
在本公开实施例中,在配置信息中,先通过RRC信令配置有M个波束信息,再通过DCI信令指示M个波束信息中的L个所述目标波束信息。
如此,本公开实施例不仅提供了另一种选取L个目标波束信息,并基于该L个目标信息波束所指示的波束方向发送SRS的方法。并且,还能不必选取一个SRS资源配置的M个波束信息中所有的波束信息,可通过DCI信令选择其中部分更加合适的目标波束信息所指示的波束方向进行SRS的发送,从而能够进一步提高SRS的传输效率。
在又一些实施例中,所述配置信息包含RRC信令、MAC信令和DCI信令,其中,所述RRC信令针对一个所述SRS资源配置有M个波束信息,所述MAC信令激活M个所述波束信息中的N个候选波束信息,所述DCI信令指示N个所述候选波束信息中的L个所述目标波束信息;其中,所述M、所述N为正整数,所述N小于所述M,所述L小于所述N。
在一实施例中,L个所述目标波束信息由一个波束信息指示域指示。
这里,所述波束指示域可以携带在所述MAC信令和所述DCI信令中,所述波束信息指示域可以为空间关系信息指示域或传输配置指示域。
这里,所述MAC信令可以从M个波束信息中选取N个候选波束信息;所述DCI信令可以从N个候选波束信息中选取L个目标波束信息。
在本公开实施例中,在配置信息中,先通过RRC信令配置有M个波束信息,然后通过MAC信令激活M个所述波束信息中的N个作为候选波束信息,最后通过DCI从N个所述候选波束信息中实际指示L个所述目标波束信息进行SRS的发送。
如此,本公开实施例提供了另一种选取L个目标波束信息,并基于该L个目标波束信息所指示的波束方向发送SRS的方法。并且,无需使用SRS配置的所有波束信息所指示的波束方向发送SRS,可以选取其中L个目标波束信息所指示的波束方向,例如,选取其中发送效果比较好的L个波束方向,进行SRS的发送;从而能够提高SRS的传输效率。
如图3所示,在一些实施例中,所述步骤S22,包括:
步骤S221:在所述SRS的同一个时频域资源上,使用L个所述目标波束信息指示的波束方向,发送所述SRS。
例如,在一应用场景中,所述SRS的时频域资源为1个;所述目标波束信息有3个,该3个目标波束信息指示的波束方向分别为Beam1、Beam2及Beam3;则所述UE在该1个时频域资源上,使用Beam1、Beam2及Beam3同时发送所述SRS。
又如,在上述应用场景中,若所述SRS的时频域资源为2个,该2个频域资源均使用Beam1、Beam2及Beam3发送所述SRS。
如此,在本公开实施例中,在一个SRS的时频域资源上,使用不同方向的波束发送所述SRS,增大了一个SRS的时频域资源上传输的空间增益,从而可以提高所述SRS传输效率。
如图4所示,在一些实施例中,所述步骤S22,包括:
步骤S222:在所述SRS的同一个频域资源上,在不同的时域资源上使用L个所述目标波束信息指示的不同波束方向,发送所述SRS。
这里,一个时域资源包括但不限于以下之一:一个时隙,一个微时隙, 或一个符号。
在一些实施例中,所述步骤S222,包括:
在所述SRS的同一个频域资源上、不同的时域资源集合上,使用L个所述目标波束信息指示的不同波束方向,发送所述SRS;
其中,所述时域资源集合包含H个连续的时域资源,其中,所述H为自然数。
在一实施例中,所述时域资源集合包括一个时域资源。在另一个实施例中,所述时域资源集合包括多个连续的时域资源。
例如,在一应用场景中,在RB0的频域资源上,有6个时隙的时域资源,该6个时隙为连续的第1时隙、第2时隙、第3时隙、第4时隙、第5时隙及第6时隙。
若所述目标波束信息有6个,该6个目标波束信息所指示的波束方向分别为Beam1、Beam2、Beam3、Beam4、Beam5及Beam6;则可以在第1时隙使用Beam1发送SRS,在第2时隙使用Beam2发送SRS,在第3时隙使用Beam3发送SRS,在第4时隙使用Beam4发送SRS,在第5时隙使用Beam5发送SRS以及在第6时隙使用Beam6发送SRS。
若所述目标波束信息有3个,该3个目标波束信息指示的波束方向分别为Beam1、Beam2及Beam3;则可以在连续的第1个时隙和第2个时隙,使用Beam1发送SRS;在连续的第3时隙和第4时隙,使用Beam2发送SRS;以及在连续的第5时隙和第6时隙,使用Beam3发送SRS。
如此,在本公开实施例中,在同一个频域资源上,在不同时域资源集合上,使用不同波束方向发送所述SRS。如此,对于不同的时间段,能够选取其发送效果比较好的波束方向进行SRS的传输,从而提高SRS的传输效率。
并且,本公开实施例可以在同一个频域资源上,在不同时域资源上使 用L个波束进行SRS的发送,提升了SRS传输的空间增益。
如图5所示,在一些实施例中,所述步骤S22,包括:
步骤S223:在所述SRS的同一个时域资源上、不同的频域资源上使用L个所述目标波束信息指示的不同波束方向,发送所述SRS。
在一实施例中,不同的频域资源中频域资源的位置为:SRS资源配置信息中的频域资源位置加上偏移量得到的位置。
这里,不同的频域资源中下一个频域资源的位置为:SRS资源配置信息中的频域资源位置加上偏移量得到的位置。
在一实施例中,所述偏移量包括一个或多个偏移量,每个偏移量包括一个或多个资源块(RB)。
例如,在一些应用场景中,在一个时域资源上,有10个RB资源,该10个RB资源分别为RB1、RB2、RB3、RB4、RB5、RB6、RB7、RB8、RB9及RB10;所述目标波束信息为2个,该2个所述目标波束指示信息所指示的波束方向分别为Beam1和Beam2。
若SRS资源配置信息中的频域资源位置为RB1、RB4、及RB7(即为第一频域资源),偏移量为一个RB,则第二频域资源为RB2、RB5及RB8;那么UE可以使用Beam1在第一频域资源上发送SRS,使用Beam2在第二频域资源上发送SRS。
在一些实施例中,所述偏移量为接收所述基站配置信令得到或者从所述UE的存储器中获取。
例如,在一实施例中,所述方法还包括:
接收所述基站发送的配置信令,其中,所述配置信令中携带所述偏移量的值。如此,在本公开实施例中,UE可以基于基站发送的配置信令中获取所述偏移量;如此,UE可以基于基站的指示,获得频域资源的偏移量。
又如,在另一实施例中,所述方法还包括:
从所述UE存储的存储资源中获取所述偏移量。如此,也可以从UE的本地存储资源中获取所述偏移量。
在本公开实施例中,UE可以在同一个时域资源上的不同的频域资源,选择与频域资源对应的波束方向进行SRS的发送;如此UE可以选择在该频域资源上使用传输效果比较好的波束方向发送SRS,从而提高SRS的传输效率。
并且,本公开实施例,可以在同一个时域资源上基于不同频域资源上使用L个波束进行SRS的发送,提升了SRS传输的频域增益和空间增益。
在一些实施例中,所述目标波束信息还用于指示一个所述参考信号标识对应的天线面板索引、传输接收点索引或物理小区标识中的一个或多个。
这里,所述物理小区标识包括:UE的服务小区的物理小区标识,或者邻小区的物理小区标识。
这里,所述天线面板索引包括以下至少之一:
天线面板对应的参考信号索引;
天线面板对应的参考信号集索引;
天线面板对应的控制资源池索引(Control Resource Set pool index)。
在本公开实施例中,所述目标波束信息用于指示参考信号标识对应的物理小区时,可以利用基于不同波束方向发送SRS,来实现向不同的物理小区发送SRS。或者,所述目标波束信息用于指示参考信号标识对应的传输接收点时,可以利用基于不同波束方向发送SRS,来实现向不同的传输接收点发送SRS。或者,可以利用基于不同波束方向发送SRS,来实现向不同的天线面板发送SRS。
如此,本公开实施例中,可以基于在不同方向上发送SRS,从而增大了一个SRS的时频域资源上传输的空间增益,从而提高SRS的传输效率。
这里需要指出的是:以下一种数据传输处理方法,是应用在基站的, 与上述应用在用户设备的所述数据传输处理方法的描述是类似的。对于本公开中应用于基站的基于所述数据传输处理方法实施例中未披露的技术细节,请参照本公开应用在用户设备的所述数据传输处理方法实施例的描述,此处不做详细阐述说明。
