具体实施方式
本公开实施例提出了确定方法及装置、通信设备、通信系统、存储介质。
第一方面,本公开实施例提出了一种确定方法,由终端执行,所述方法包括:
确定上行链路许可资源是否包括SBFD的上行子带;和/或
确定待发送数据对应的逻辑信道是否被允许在所述SBFD的上行子带上传输。
在上述实施例中,终端会确定上行链路许可资源是否包括SBFD的上行子带,和/或,会确定待发送数据对应的逻辑信道是否被允许在SBFD的上行子带上传输,以便终端后续可以基于确定结果来进行逻辑信道优先级(logical channel prioritization,LCP)处理。可选地,上述的SBFD的上行子带用于实现SBFD的上行传输,其中,当上行链路许可资源包括SBFD的上行子带时,可以认为该上行链路许可资源用于实现SBFD,即可能会出现:终端在基于该上行链路许可资源向网络设备发送上行数据时,该网络设备还会同时在同一时域位置的其他子带上向其他终端发送下行数据,此时,由于同一时域位置上的上下行数据同时传输,则使得终端的上行传输会存在干扰;以及,当上行链路许可资源不包括SBFD的上行子带时,可以认为该上行链路许可资源不用于实现SBFD,即:终端在基于该上行链路许可资源向网络设备发送上行 数据时,该网络设备不会同时在同一时域位置的其他子带上向其他终端发送下行数据,此时,由于同一时域位置上的上下行数据不同时传输,则使得终端的上行传输不会受到干扰。
可选地,上述的“待发送数据对应的逻辑信道是否被允许在SBFD的上行子带上传输”可以理解为:是否允许终端利用该SBFD的上行子带来向网络设备传输待发送数据对应的逻辑信道,其中,由于上述的SBFD的上行子带用于SBFD,因此,当利用SBFD的上行子带传输待发送数据对应的逻辑信道时,可能会对该逻辑信道的传输造成干扰。基于此,针对通信质量要求较高的数据(如较为重要的数据或者需要高可靠度的数据),可以配置其对应的逻辑信道不允许在SBFD的上行子带传输,以避免干扰,针对通信质量要求较低的数据(如较为不重要的数据或者不需要高可靠度的数据),可以配置其对应的逻辑信道允许在SBFD的上行子带传输。
由此,当终端确定出上行链路许可资源是否包括SBFD的上行子带,和/或,确定出待发送数据对应的逻辑信道是否被允许在SBFD的上行子带上传输时,终端可以基于确定结果判断出利用该上行链路许可资源进行上行传输时是否会存在干扰,和/或,会判断出该待发送数据是否为通信质量要求较高的数据,则终端会进一步确定后续在进行LCP处理时是否选择该逻辑信道,以此达到“对于通信质量要求较高的数据,可以不进行SBFD,而对于通信质量要求较低的数据才进行SBFD”的目的,以避免出现“对于通信质量要求较高的数据进行SBFD时,由于SBFD会存在干扰而导致该数据的传输面临服务质量(Quality of Service,QoS)无法满足”的情况,从而保证了通信质量要求较高的数据的QoS,且还能充分利用子带全双工所提供的上行资源,确保了通信质量和通信稳定性。
结合第一方面的一些实施例,在一些实施例中,所述方法还包括以下至少之一:
所述终端确定所述上行链路许可资源包括SBFD的上行子带且允许所述逻辑信道在所述SBFD的上行子带上传输,所述终端基于所述上行链路许可资源对所述逻辑信道进行逻辑信道优先级LCP处理;
所述终端确定所述上行链路许可资源包括SBFD的上行子带且不允许所述逻辑信道在所述SBFD的上行子带上传输,所述终端基于所述上行链路许可资源进行LCP处理时不选择所述逻辑信道;
所述终端确定所述上行链路许可资源不包括SBFD的上行子带,所述终端基于所述上行链路许可资源对所述逻辑信道进行LCP处理。
可选地,上述的“基于上行链路许可资源对该待发送数据对应的逻辑信道进行LCP处理(或称为:基于上行链路许可资源进行LCP处理时选择待发送数据对应的逻辑信道)”可以理解为:通过对待发送数据对应的逻辑信道进行LCP处理以便后续基于上行链路许可资源发送该待发送数据对应的逻辑信道;可选地,上述的“基于上行链路许可资源进行LCP处理时不选择逻辑信道”可以理解为:终端不利用该上行链路许可资源发送该逻辑信道。
则结合上述内容,在本公开实施例中,当终端确定上行链路许可资源包括SBFD的上行子带且允许逻辑信道在SBFD的上行子带上传输时,说明利用该上行链路许可资源发送数据时可能会存在干扰,且待发送数据为通信质量要求较低的数据,此时,虽然利用该上行链路许可资源传输待发送数据对应的逻辑信道时会存在干扰,但鉴于该待发送数据为通信质量要求较低,则即使存在干扰也不会造成太大影响,因此可以基于上行链路许可资源对该逻辑信道进行LCP处理,以便后续利用该上行链路许可资源发送该逻辑信道。可选地,当终端确定上行链路许可资源包括SBFD的上行子带且不允许逻辑信道在SBFD的上行子带上传输时,说明利用该上行链路许可资源发送数据时可能会存在干扰,且待发送数据为通信质量要求较高的数据,此时,若利用该上行链路许可资源传输待发送数据对应的逻辑信道时会存在干扰,而由于待发送数据为通信质量要求较高的数据,因此,为了避免其传输时存在干扰,终端在基于上行链路许可资源进行LCP处理时可以不选择逻辑信道,也即是,终端不利用该上行链路许可资源发送该逻辑信道,以此来避免出现“利用用于SBFD的上行链路许可资源传输通信质量要求较高的数据时,导致该数据的传输面临QoS无法满足”的情况,确保通信质量和通信稳定性。可选地,当终端确定上行链路许可资源不包括SBFD的上行子带,则说明该上行链路许可资源不用于SBFD,此时,通过该上行链路许可资源传输数据时不会存在干扰,则终端无需考虑逻辑信道是否被允许在SBFD的上行子带上传输,而可以直接基于上行链路许可资源对逻辑信道进行LCP处理。
由此可知,在上述实施例之中,当终端需要进行SBFD时,对于通信质量要求较高的数据,可以选择不进行SBFD,而对于通信质量要求较低的数据才进行SBFD,由此避免出现“对于通信质量要求较高的 数据进行SBFD时,由于SBFD会存在干扰而导致该数据的传输面临QoS无法满足”的情况,保证了通信质量要求较高的数据的QoS,且还能充分利用子带全双工所提供的上行资源,从而确保了通信质量和通信稳定性。

下述本公开实施例可以应用于图1所示的通信系统100、或部分主体,但不限于此。图1所示的各主体是例示,通信系统可以包括图1中的全部或部分主体,也可以包括图1以外的其他主体,各主体数量和形态为任意,各主体之间的连接关系是例示,各主体之间可以不连接也可以连接,其连接可以是任意方式,可以是直接连接也可以是间接连接,可以是有线连接也可以是无线连接。

可选地,通信系统中主要是对网络设备侧实现了SBFD,而终端侧并非是SBFD。其中,终端侧无法同时进行数据的收发,其是同一时刻进行数据的发送或接收,而网络设备侧可以在同一时刻下进行数据的发送和接收。可选地,网络设备侧的SBFD主要可以包括:网络设备接收终端1发送的数据,同时,网络设备还向其他终端(如终端2)发送数据。可选地,网络设备在进行SBFD之前,通常会先向终端配置SBFD资源,该SBFD资源中TDD的单个载波内划分有频域上不交叠的上行子带(UL SBFD subband)和下行子 带(DL SBFD subband),可选地,上行子带或下行子带可以由一个资源块或多个连续的资源块组成,该上行子带可以在频域处于载波的一侧或者是载波的中部,该上行子带用于上行传输,下行子带用于下行传输。可选地,该SBFD资源可以用于实现SBFD,例如:网络设备可以在同一时刻通过该SBFD资源中的上行子带接收终端发送的数据,同时通过该SBFD资源中下行子带向其他终端发送数据,以此实现网络设备侧的SBFD。可选地,图1B是根据本公开实施例示出的SBFD资源的结构示意图,图1B中“D”指示下行子带,“U”指示上行子带。如图1B所示,在第二、第三和第四个时隙(Slot)中分别划分有频域上不交叠的上行子带和下行子带。
可选地,当终端使用SBFD资源中的上行子带向网络设备发送数据时,可能会受到各种干扰,比如同时刻下该网络设备对于其他终端的下行传输会干扰到该终端基于SBFD资源中上行子带的上行传输,其中,为了防止SBFD中的干扰,虽然有一些抑制干扰的技术,但是干扰并不能完全消除。并且针对一些不支持SBFD的网络设备(如另一个运营商的网络设备)来说,由于其不支持SBFD,因此,其根本不会采用干扰消除技术,则使得该不支持SBFD的网络设备的下行传输对该终端基于SBFD资源中上行子带的上行传输也造成较大的干扰,因此,SBFD资源内的上行子带上的上行传输同非SBFD资源内的上行子带上的上行传输相比,干扰较大。此时,若终端要通过SBFD资源的上行子带传输较为重要的数据,则可能会使得SBFD资源内的上行子带的上行传输会面临服务质量(Quality of Service,QoS)无法满足的问题,且还可能造成重要数据的传输失败。
图2A是根据本公开实施例示出的确定方法的交互示意图。如图2A所示,本公开实施例涉及确定方法,用于通信系统100,上述方法包括:
步骤2101、网络设备向终端发送第一配置。
可选地,该第一配置可以用于配置逻辑信道,可选地,每一第一配置可以用于配置一个逻辑信道。
可选地,该第一配置可以用于配置逻辑信道是否允许在SBFD的上行子带上传输,和/或,逻辑信道对应的相关参数等。
可选地,终端可以基于逻辑信道对应的第一配置(例如第一配置中的逻辑信道对应的相关参数)来针对待发送数据选择出用于发送该待发送数据的逻辑信道。
可选地,在一些实施例之中,对于用来发送通信质量要求较高的数据(即较为重要的数据或者需要高可靠度的数据)的逻辑信道,第一配置可以配置该逻辑信道不允许在SBFD的上行子带上传输;对于用来发送通信质量要求较低的数据(即较不重要的数据或者不需要高可靠度的数据)的逻辑信道,第一配置可以配置该逻辑信道允许在SBFD的上行子带上传输。具体的,之所以“将用来发送通信质量要求较高的数据的逻辑信道配置为不允许在SBFD的上行子带上传输”主要是由于:通过SBFD的上行子带发送数据时可能会存在干扰(关于该部分内容的介绍可参考上述内容描述),此时,若使得“用来发送通信质量要求较高的数据的逻辑信道”在SBFD的上行子带上传输,则会对该通信质量要求较高的数据的传输产生干扰,影响其通信质量,因为,为了避免影响该类数据的通信质量,需要将用来发送通信质量要求较高的数据的逻辑信道配置为不允许在SBFD的上行子带上传输。同理的,当某逻辑信道用于传输通信质量要求较低的数据时,由于该逻辑信道所传输的数据的通信质量要求较低,因此,即使利用SBFD的上行子带传输该逻辑信道会产生干扰,也不会造成太大影响,则可以将用来发送通信质量要求较高的数据的逻辑信道配置为允许在SBFD的上行子带上传输,以此来充分利用子带全双工所提供的上行资源。
可选地,上述的第一配置可以承载于LogicalChannelConfig IE中,示例的,该第一配置例如可以为:

可选地,上述的“sbfd-UL-SubbandAllowed-r19ENUMERATED”可以用于配置逻辑信道是否允许在SBFD的上行子带上传输,其中,当“sbfd-UL-SubbandAllowed-r19ENUMERATED”为“true”时,说明逻辑信道允许在SBFD的上行子带上传输,当“sbfd-UL-SubbandAllowed-r19ENUMERATED”为“false”时,说明逻辑信道不允许在SBFD的上行子带上传输。
可选地,上述的sbfd-UL-SubbandAllowed IE的后缀r19表示在3GPP Rel-19引入。该IE也可能在3GPP的其他Release被引入,那么后缀就会有相应的变化,例如当在Rel-20引入时,后缀则为r20。
可选地,网络设备可以通过RRC信令向终端发送上述的第一配置。
需要说明的是,上述的“基于通信质量高低来配置不同逻辑信道是否允许在SBFD的上行子带上传输”仅是示例性描述,应当理解,也可以基于除通信质量外的其他因素来配置不同逻辑信道是否允许在SBFD的上行子带上传输,本公开对此不作限定。
步骤2102、网络设备向终端发送上行链路许可(UpLink grant,UL grant)资源。
可选地,终端可以接收网络设备发送的上行链路许可资源。可选地,该上行链路许可资源可以用于终 端来向网络设备发送上行数据。
可选地,在一些实施例之中,上述的“网络设备向终端发送上行链路许可资源”可以包括:网络设备向终端配置上行链路许可资源对应的全部信息(如:时域参数、周期等),以便当终端后续有上行数据需要发送时,可以直接利用该上行链路许可资源进行上行传输。
或者,在另一些实施例之中,上述的“网络设备向终端发送上行链路许可资源”可以包括:网络设备向终端配置上行链路许可资源对应的部分信息(例如周期等),之后,网络设备再向终端指示该上行链路许可资源对应的剩余信息(如:时域、频域参数等)来激活该上行链路许可资源,如当终端需要进行上行传输时,网络设备再向终端指示该剩余信息,以便当终端有上行数据需要发送时,可以直接利用该上行链路许可资源进行上行传输。
可选地,本步骤后续的步骤2103-2107可以是当终端要利用上行链路许可资源进行上行传输之前所执行的。
步骤2103、终端确定上行链路许可资源是否包括SBFD的上行子带。
可选地,该SBFD的上行子带可以理解为用于实现SBFD的上行子带,或者,该SBFD的上行子带可以理解为SBFD资源中的上行子带等,本公开对此不作限定。其中,关于SBFD资源的相关介绍可以参考图2A实施例之前的描述内容。
可选地,在一些实施例之中,上述的“SBFD的上行子带或SBFD资源中的上行子带”可以包括以下至少之一:
SBFD的下行时域单元中的上行子带;SBFD的下行时域单元例如可以为图1B中的第二、第三和第四个时隙。以及,该SBFD的下行时域单元中的上行子带例如可以为图1B中的第二、第三和第四个时隙中的上行子带;
SBFD的灵活时域单元中的上行子带;可选地,SBFD的灵活时域单元中除了包括上行子带外还可以包括下行子带,以此实现网络设备侧的SBFD;
SBFD的上行时域单元中的上行子带。可选地,SBFD的上行时域单元中除了包括上行子带外还可以包括下行子带,以此实现网络设备侧的SBFD。
可选地,上述的时域单元可以为符号或者时隙。
可选地,在一些实施例之中,当上行链路许可资源包括SBFD的上行子带时,可以认为该上行链路许可资源用于实现SBFD,或者,可以认为该上行链路许可资源中包括SBFD资源,即可能会出现:终端在基于该上行链路许可资源中的第一字带(即上行子带)向网络设备发送上行数据时,该网络设备还会基于该上行链路许可资源中的下行子带同时向其他终端发送下行数据,此时,由于上下行数据同时传输,则使得终端在第一字带上所进行的上行传输会存在干扰;可选地,在一些实施例之中,当上行链路许可资源不包括SBFD的上行子带时,可以认为该上行链路许可资源不用于实现SBFD,即:终端在基于该上行链路许可资源中的第一字带向网络设备发送上行数据时,该网络设备不会同时向其他终端发送下行数据,此时,由于上下行数据未同时传输,则终端在第一字带上所进行的上行传输不会存在干扰。
可选地,在一些实施例之中,上述的“确定上行链路许可资源是否包括SBFD的上行子带”可以理解为是用于确定:终端在利用该上行链路许可资源发送上行数据时是否会存在干扰,以便终端后续可以基于“终端在利用该上行链路许可资源发送上行数据时是否存在干扰”来确定后续是否选择待发送数据对应的逻辑信道进行逻辑信道优先级处理(Logical Channel Prioritization,LCP)处理(关于LCP处理的详细介绍会在后续步骤2105进行描述)。可选地,当确定上行链路许可资源包括SBFD的上行子带时,即可以认为:终端在利用该上行链路许可资源发送上行数据时可能会存在干扰,当确定上行链路许可资源不包括SBFD的上行子带时,即认为:终端在利用该上行链路许可资源发送上行数据时不会存在干扰。
可选地,在一些实施例之中,上述的终端确定上行链路许可资源是否包括SBFD的上行子带的方法可以包括以下至少之一:
上行链路许可资源的所有时域单元(如所有符号或所有时隙)中均包括SBFD的上行子带,确定上行链路许可资源包括SBFD的上行子带;
上行链路许可资源的至少一个时域单元中不包括SBFD的上行子带,确定上行链路许可资源不包括SBFD的上行子带。
可选地,在另一些实施例之中,终端确定上行链路许可资源是否包括SBFD的上行子带的方法可以包括以下至少之一:
上行链路许可资源的至少一个时域单元中包括SBFD的上行子带,确定上行链路许可资源包括SBFD的上行子带;
上行链路许可资源的所有时域单元中均不包括SBFD的上行子带,确定上行链路许可资源不包括SBFD的上行子带。
可选地,在又一些实施例之中,上述的终端确定上行链路许可资源是否包括SBFD的上行子带的方法可以包括以下至少之一步骤:
步骤a、确定第一阈值。
该第一阈值可以大于0,小于或等于1,例如可以为50%;
可选地,该第一阈值可以是协议约定的,和/或,该第一阈值可以是网络设备配置至终端的,例如,该第一阈值可以是网络设备通过无线资源控制(Radio Resource Control,RRC)信令和/或媒体接入控制层控制单元(Medium Access Control Control Element,MAC CE)信令配置至终端的。
步骤b、确定上行链路许可资源中包括SBFD的上行子带的时域单元的数量与上行链路许可资源中时域单元的总数量之间的比值;
步骤c、比值大于或等于第一阈值,确定上行链路许可资源包括SBFD的上行子带;
步骤d、比值小于第一阈值,确定上行链路许可资源不包括SBFD的上行子带。
可选地,在一些实施例之中,不同逻辑信道可以分别对应有第一阈值,也即是,每个逻辑信道单独配置第一阈值,此时,在确定上行链路许可资源是否包括SBFD的上行子带时,可以是基于待发送数据对应的逻辑信道所对应的第一阈值确定上行链路许可资源是否包括SBFD的上行子带。可选地,此处的待发送数据、待发送数据对应的逻辑信道、上行链路许可资源之间的关系可以为:待发送数据对应的逻辑信道可以理解为该待发送数据的承载,以及,上行链路许可资源可以理解为:终端利用该上行链路许可资源承载该待发送数据对应的逻辑信道以将该待发送数据对应的逻辑信道发送至网络设备。基于此,当每个逻辑信道单独配置第一阈值时,则在确定上行链路许可资源是否包括SBFD的上行子带时,可以确定上行链路许可资源中包括SBFD的上行子带的时域单元的数量与上行链路许可资源中时域单元的总数量之间的比值是否大于或等于待发送数据对应的逻辑信道所对应的第一阈值,当大于或等于时,确定上行链路许可资源包括SBFD的上行子带;当小于时,确定上行链路许可资源不包括SBFD的上行子带。
可选地,当该第一阈值由RRC信令为每个逻辑信道单独配置时,该第一阈值可以配置在IE LogicalChannelConfig中。
或者,在另一些实施例之中,不同MAC实体分别对应有第一阈值,也即是,每个MAC实体单独配置第一阈值,此时,在确定上行链路许可资源是否包括SBFD的上行子带时,可以是基于待发送数据对应的逻辑信道关联的MAC实体所对应的第一阈值确定上行链路许可资源是否包括SBFD的上行子带。可选地,此处的待发送数据对应的逻辑信道、MAC实体之间的关系可以为:一个MAC实体可以关联至少一个逻辑信道,该MAC实体用于对所关联的至少一个逻辑信道进行LCP处理。基于此,当每个MAC实体单独配置第一阈值时,则在确定上行链路许可资源是否包括SBFD的上行子带时,可以确定上行链路许可资源中包括SBFD的上行子带的时域单元的数量与上行链路许可资源中时域单元的总数量之间的比值是否大于或等于待发送数据对应的逻辑信道关联的MAC实体所对应的第一阈值,当大于或等于时,确定上行链路许可资源包括SBFD的上行子带;当小于时,确定上行链路许可资源不包括SBFD的上行子带。
可选地,当该第一阈值由RRC信令为每个MAC实体单独配置时,该第一阈值可以配置在IE MAC-CellGroupConfig中。
或者,在另一些实施例之中,不同终端分别对应有第一阈值,也即是,每个终端单独配置第一阈值,此时,在确定上行链路许可资源是否包括SBFD的上行子带时,可以是基于终端对应的第一阈值确定上行链路许可资源是否包括SBFD的上行子带。可选地,可以确定上行链路许可资源中包括SBFD的上行子带的时域单元的数量与上行链路许可资源中时域单元的总数量之间的比值是否大于或等于该终端对应的第一阈值,当大于或等于时,确定上行链路许可资源包括SBFD的上行子带;当小于时,确定上行链路许可资源不包括SBFD的上行子带。
可选地,在又一些实施例之中,上述的终端确定上行链路许可资源是否包括SBFD的上行子带的方法可以包括以下至少之一步骤:
步骤1、确定第二阈值;
该第二阈值为正整数,例如可以为2个。
可选地,该第二阈值可以是协议约定的,和/或,该第二阈值可以是网络设备配置至终端的,例如,该第二阈值可以是网络设备通过RRC信令和/或MAC CE信令配置至终端的。
步骤2、上行链路许可资源中包括SBFD的上行子带的时域单元的数量大于或等于第二阈值,确定上行链路许可资源包括SBFD的上行子带。
步骤3、上行链路许可资源中包括SBFD的上行子带的时域单元的数量小于第二阈值,确定上行链路许可资源不包括SBFD的上行子带。
可选地,在一些实施例之中,不同逻辑信道可以分别对应有第二阈值,此时,确定上行链路许可资源是否包括SBFD的上行子带可以包括:基于待发送数据对应的逻辑信道所对应的第二阈值确定上行链路许可资源是否包括SBFD的上行子带;或者,不同MAC实体分别对应有第二阈值,此时,确定上行链路许可资源是否包括SBFD的上行子带可以包括:基于待发送数据对应的逻辑信道关联的MAC实体所对应的第二阈值确定上行链路许可资源是否包括SBFD的上行子带;或者,不同终端分别对应有第二阈值,此时,确定上行链路许可资源是否包括SBFD的上行子带可以包括:基于终端对应的第二阈值确定上行链路许可资源是否包括SBFD的上行子带。关于该部分的详细介绍可以参考上述对于第一阈值的相关内容。
可选地,当第二阈值由RRC信令为每个逻辑信道单独配置时,第二阈值可以配置在IE LogicalChannelConfig中。当该第二阈值由RRC信令为每个MAC实体单独配置时,第二阈值可以配置在IE MAC-CellGroupConfig中。
可选地,在又一些实施例之中,上述的确定上行链路许可资源是否包括SBFD的上行子带可以包括以下步骤:
步骤一、接收网络设备发送的第一信息。
步骤二、基于第一信息确定上行链路许可资源是否包括SBFD的上行子带。
可选地,该第一信息可以用于指示上行链路许可资源是否包括SBFD的上行子带;该第一信息例如可以承载于物理下行控制信道(physical downlink control channel,PDCCH)中。
可选地,在一些实施例之中,终端可以不自身确定上行链路许可资源是否包括SBFD的上行子带,而由网络设备指示上行链路许可资源是否包括SBFD的上行子带,由此可以提高“上行链路许可资源是否包括SBFD的上行子带”确定时灵活性。具体而言,前述内容描述到“确定上行链路许可资源是否包括SBFD的上行子带”实质是用于确定:终端在利用该上行链路许可资源发送上行数据时是否会存在干扰。其中,并非是当上行链路许可资源包括SBFD的上行子带时,就绝对会使得终端在利用该上行链路许可资源发送上行数据时存在干扰,有可能还会出现“上行链路许可资源包括SBFD的上行子带,但利用该上行链路许可资源发送上行数据时不会存在干扰”的情况,例如,虽然上行链路许可资源中包括第一字带,但是,当终端在基于上行链路许可资源中的SBFD的上行子带向网络设备发送上行数据时,该网络设备并没有进行下行调度,或者,该网络设备所进行的下行调度对终端基于SBFD的上行子带的上行传输的干扰不存在或大幅降低,则认为利用该上行链路许可资源发送上行数据时不会存在干扰。因此,在一些实施例之中,即使当上行链路许可资源中包括SBFD的上行子带,但是,网络设备在该上行链路许可资源中的SBFD的上行子带相邻的下行子带中没有调度下行传输,或者,所调度的下行传输对SBFD的上行子带的上行传输不会产生干扰或产生的干扰较低,则网络设备向终端发送的第一信息会指示上行链路许可资源中不包括SBFD的上行子带。
可选地,在一些实施例之中,网络设备可以通过在第一信息中的下行链路信息中用不同的比特值来指示上行链路许可资源是否包括SBFD的上行子带,例如,当第一信息中的下行链路信息中的比特值为第一值(如1)时,指示上行链路许可资源包括SBFD的上行子带,当第一信息中的下行链路信息中的比特值为第二值(如0)时,指示上行链路许可资源不包括SBFD的上行子带。
可选地,在一些实施例之中,终端通常会被配置重复传输(或称为聚合(bundle)),该重复传输的次数(REPETITION_NUMBER)可以由网络设备配置,并且,每一次传输会分别对应不同上行链路许可 资源,即:重复传输中的每次传输均可以视为单独的上行链路许可。其中,当终端被配置重复传输时,终端在确定上行链路许可资源是否包括SBFD的上行子带时,可以是确定重复传输中的任一次传输(例如第一次传输)对应的上行链路许可资源是否包括SBFD的上行子带,和/或,可以是确定重复传输中的N次传输对应的上行链路许可资源是否包括SBFD的上行子带,N大于或等于1。例如,可以是确定第一次传输和第二次传输对应的上行链路许可资源中是否包括SBFD的上行子带,或者,可以是确定所有传输对应的上行链路许可资源中是否包括SBFD的上行子带。
步骤2104、终端基于待发送数据对应的逻辑信道所对应的第一配置确定待发送数据对应的逻辑信道是否被允许在SBFD的上行子带上传输。
步骤2105、终端确定上行链路许可资源包括SBFD的上行子带且允许逻辑信道在SBFD的上行子带上传输,终端基于上行链路许可资源对逻辑信道进行LCP处理。
可选地,当终端确定上行链路许可资源包括SBFD的上行子带且允许逻辑信道在SBFD的上行子带上传输时,说明利用该上行链路许可资源发送数据时可能会存在干扰,且待发送数据为通信质量要求较低的数据,此时,虽然利用该上行链路许可资源传输待发送数据对应的逻辑信道时会存在干扰,但鉴于该待发送数据为通信质量要求较低的数据,则即使存在干扰也不会造成太大影响,因此,此时可以基于上行链路许可资源对该逻辑信道进行LCP处理,以便后续利用该上行链路许可资源发送该逻辑信道,以此来充分利用子带全双工所提供的上行资源。
可选地,上述LCP处理例如可以理解为:对于每一个上行链路许可资源,终端的MAC层进行LCP处理,来决定每个逻辑信道是否在该上行链路许可资源上传输,以及传输多少数据。在LCP操作开始时,MAC会根据逻辑信道对应的第一配置来选择能够在当前上行链路许可资源中所传输的逻辑信道。可选地,LCP可以选择满足以下条件的逻辑信道:该逻辑信道被配置允许在SBFD的上行子带上传输。
步骤2106、终端确定上行链路许可资源包括SBFD的上行子带且不允许逻辑信道在SBFD的上行子带上传输,终端基于上行链路许可资源进行LCP处理时不选择逻辑信道。
可选地,此处的“基于上行链路许可资源进行LCP处理时不选择逻辑信道”例如可以理解为:不利用该上行链路许可资源发送该待发送数据对应的逻辑信道。
可选地,当终端确定上行链路许可资源包括SBFD的上行子带且不允许逻辑信道在所述SBFD的上行子带上传输时,说明利用该上行链路许可资源发送数据时可能会存在干扰,且待发送数据为通信质量要求较高的数据,此时,若利用该上行链路许可资源传输待发送数据对应的逻辑信道时会存在干扰,而由于待发送数据为通信质量要求较高的数据,因此,为了避免其传输时存在干扰,终端在基于上行链路许可资源进行LCP处理时不选择逻辑信道,也即是,终端不利用该上行链路许可资源发送该逻辑信道,以此来避免出现“利用用于SBFD的上行链路许可资源传输通信质量要求较高的数据时,由于SBFD会存在干扰而导致该数据的传输面临QoS无法满足”的情况,确保通信质量和通信稳定性。
步骤2107、终端确定上行链路许可资源不包括SBFD的上行子带,终端基于上行链路许可资源对逻辑信道进行LCP处理。
可选地,当终端确定上行链路许可资源不包括SBFD的上行子带,则说明该上行链路许可资源不用于SBFD,此时,通过该上行链路许可资源传输数据时不会存在干扰,则终端无需考虑逻辑信道是否被允许在SBFD的上行子带上传输,而可以直接基于上行链路许可资源对逻辑信道进行LCP处理,以便后续利用该上行链路许可资源发送该逻辑信道,以此来充分利用子带全双工所提供的上行资源。

步骤4101、网络设备向终端发送第一配置。

关于步骤4101-4102的详细介绍可以参考上述实施例的内容。
本公开实施例所涉及的确定方法可以包括步骤S4101~步骤S4102中的至少一者。例如,步骤S4101可以作为独立实施例来实施,步骤S4102可以作为独立实施例来实施,但不限于此。
在本实施方式或实施例中,在不矛盾的情况下,各步骤可以独立、任意组合或交换顺序,可选方式或可选例可以任意组合,且可以与其他实施方式或其他实施例的任意步骤之间进行任意组合。
以下为对上述方法的示例性介绍。
子带全双工(Subband Full Duplex,SBFD)是3GPP在Rel-18中研究的一种新的双工制式。该制式通过在TDD单个载波内划分不交叠的上/下行子带(subband)、并在子带上分别进行数据的发送和接收,可以实现基站侧的全双工。
在子带全双工制式下,一个SBFD子带由一个资源块或多个连续的资源块组成,用来传输同一链路方向(下行或上行)的数据。SBFD符号是指包含SBFD操作的子带的符号(symbol)。在Rel-18的研究中,TDD载波的一个SBFD符号中最多有一个上行子带用于SBFD操作。该上行子带在频域可以处于载波的一侧或者是载波的中部。网络配置SBFD子带的时域和频域资源。
图1B为子带全双工(SBFD)示例,其中“D”指示下行,“U”指示上行。在第二、第三和第四个时隙中配置有SBFD符号,其中包含上行子带。
对于每一个上行链路许可(UL grant)的资源,UE的MAC层进行逻辑信道优先级处理(Logical Channel Prioritization,LCP)的操作,来决定每个逻辑信道是否传输,以及传输多少数据。在LCP操作开始时,MAC会根据RRC的配置来选择能够在当前上行链路许可资源中所传输的逻辑信道。LCP选择满足以下所有条件的逻辑信道:
-当配置allowedSCS-List时,allowedSCS-List中允许的子载波间隔索引(Subcarrier Spacing index)的集合包括与上行链路许可相关联的子载波间隔索引;
-当配置maxPUSCH-Duration时,maxPUSCH-Duration配置的值要小于等于上行链路许可的PUSCH传输长度;
-当配置confiuredGrantType1Allowed并且上行链路许可是Configured Grant type 1时,configuredGrantType1Allowed取值为true;
-当配置allowedServingCells时,allowedServingCells包含了上行链路许可所对应的小区的信息(这个参数不适用于CA duplication去激活的情况);
-当配置allowedCG-List时,allowedCG-List包含了上行链路许可所对应的configured grant index;
-当配置allowedPHY-PriorityIndex时,allowedPHY-PriorityIndex包含了动态上行链路许可(dynamic UL grant)所对应的priority index;
-当配置allowedHARQ-mode时,allowedHARQ-mode包含了上行链路许可所对应的HARQ进程所允许的上行HARQ模式(allowed UL HARQ mode)。
这些与LCP选择相关的RRC参数定义在3GPP TS 38.331中的IE LogicalChannelConfig中,如下所示:

在上行链路传输中,一个传输块(TB)可以采用多时隙重复发送,被称为聚合(bundle)。其中第一次传输之后的传输是之前传输的HARQ重传,只是不需要等待HARQ反馈。一个传输块的传输次数REPETITION_NUMBER由物理层提供。每次传输均视为单独的上行链路许可。
上述方法中存在的技术问题:
当使用子带全双工时,在SBFD的符号内的上行子带(UL SBFD subband)传输的数据可能会受到各种干扰,比如同gNB的下行传输会干扰上行子带的接收,相邻gNB(相同运营商或不同运营商)的下行传输也会干扰上行子带的接收。虽然有一些抑制干扰的技术,但是干扰并不能完全消除。尤其是当一些不支持子带全双工的gNB(比如另一个运营商的gNB)没有采用干扰消除技术,其下行传输会对SBFD的符号内的上行子带造成较大的干扰。所以SBFD的符号内的上行子带同非SBFD符号的上行符号相比,上行传输的干扰程度不同。对于需要高可靠度的数据而言,在SBFD的符号内的上行子带上传输可能会面临QoS无法满足的问题。当前并没有能够限制在SBFD符号内的上行子带上传输数据的方法。
本公开所要并且所能解决的技术问题
本公开提供一种在逻辑信道优先级处理时根据上行链路许可是否包含子带全双工的上行子带来选择逻辑信道的方法。通过该方法,需要高可靠度的数据可以不在子带全双工的上行子带传输,而其他数据可以在上行子带传输。这样既能充分利用子带全双工所提供的上行资源,也能保证需要高可靠度的数据的QoS。
本公开技术方案的内容
本公开提供一种在逻辑信道优先级处理时根据上行链路许可是否包含子带全双工的上行子带来选择逻辑信道的方法。在该方法中,网络(gNB)通过RRC信令来配置每个逻辑信道是否能在子带全双工的上行子带来传输。对于每一个上行链路许可,如果资源包含子带全双工的上行子带,UE的MAC层根据RRC信令的配置来决定选择哪些逻辑信道继续进行逻辑信道优先级处理。具体来说就是在现有的逻辑信道选择步骤中,除了考虑已有的条件外(例如allowedSCS-List、maxPUSCH-Duration),还需要额外考虑上行链路许可的资源是否包含子带全双工的上行子带。如果上行链路许可的资源包含子带全双工的上行子带并且RRC配置允许逻辑信道在子带全双工的上行子带来传输,那么该逻辑信道被选择继续进行后续的逻辑信道优先级处理流程。否则,该逻辑信道不被选择,从而不参与后续的逻辑信道优先级处理流程。
子带全双工的上行子带即可以指下行符号(“D”)或灵活符号(“F”)中的上行子带,也可以是指上行符号(“U”)中的上行子带。
由于上行链路的时域资源可以包含多个符号,在逻辑信道优先级处理过程中判断上行链路许可的资源是否包含子带全双工的上行子带有五个选项:
选项a:当上行链路许可的资源包含的所有符号均有子带全双工的上行子带,即认为上行链路许可的资源包含子带全双工的上行子带;
选项b:当上行链路许可的资源至少包含一个符号有子带全双工的上行子带,即认为上行链路许可的资源包含子带全双工的上行子带;
选项c:定义一个比例的阈值,该阈值既可以在标准中预定义(例如50%),也可以由网络来配置阈值。网络配置可以由RRC信令来配置,或者由MAC CE来配置。该阈值可以是每个逻辑信道单独配置,也可以是每个MAC实体单独配置,或者是每个UE来配置。当该阈值由RRC信令为每个逻辑信道单独配置时,阈值可以配置在IE LogicalChannelConfig中。当该阈值由RRC信令为每个MAC实体单独配置时,阈值可以配置在IE MAC-CellGroupConfig中。在该选项中,当上行链路许可的资源中有子带全双工的上行子带的符号的个数与上行链路许可的资源中所有的符号的个数比值大于等于(或者是大于)阈值时,即认为上行链路许可的资源包含子带全双工的上行子带。选型a和选项b可以认为是选项c的特例,比如选项a可以认为是标准中预定义阈值为100%,而选项b可以认为是标准中预定义一个非常小的阈值(例如1%)。
选项d:定义一个符号个数的阈值,该阈值既可以在标准中预定义(例如2个),也可以由网络来配置阈值。网络配置可以由RRC信令来配置,或者由MAC CE来配置。该阈值可以是每个逻辑信道单独配置,也可以是每个MAC实体单独配置,或者是每个UE来配置。当该阈值由RRC信令为每个逻辑信道单独配置时,阈值可以配置在IE LogicalChannelConfig中。当该阈值由RRC信令为每个MAC实体单独配置时,阈值可以配置在IE MAC-CellGroupConfig中。在该选项中,当上行链路许可的资源中有子带全双工的上行子带的符号的个数大于等于(或者是大于)阈值时,即认为上行链路许可的资源包含子带全双工的上行子带。选项b可以认为是选项d的特例,比如选项b可以认为是标准中预定义的阈值为1。
选项e:在物理层PDCCH中指示在逻辑信道优先级处理是否认为PDCCH中指示的上行链路许可包含子带全双工的上行子带。例如在PDCCH中的下行链路信息中用1bit来指示。物理层PDCCH的动态指示提供了更多的灵活度。例如,当gNB在与子带全双工的上行子带相邻的下行子带没有调度新型传输时,子带全双工的上行子带所受的自干扰将不存在或大幅降低。因此即使上行链路许可的资源中有子带全双工的上行子带,gNB也可以指示在逻辑信道优先级处理过程可以认为该上行链路许可并未包含子带全双工的上行子带,从而允许需要高可靠度的逻辑信道使用该上行链路许可。
当上行链路的传输块采用多时隙聚合重复发送时,在逻辑信道优先级处理过程中判断上行链路许可的资源是否包含子带全双工的上行子带有两个选项:
选项1:仅根据聚合中的一次传输来判断,例如根据聚合(bundle)中的第一次传输来判断。之前所述的选项a、b、c、d、e所指的上行链路许可的资源是指聚合中的某次传输(例如第一次传输)。
选项2:根据聚合中的所有传输的一个子集(例如聚合中的所有传输)来判断。之前所述的选项a、b、c、d、e所指的上行链路许可的资源是指聚合中的该子集所对应的各个上行链路许可所对应的所有资源。
以下为在3GPP TS 38.331中的LogicalChannelConfig IE中添加控制能否在子带全双工的上行子带传输数据的一个示例。该IE包含单个逻辑信道的配置。加下划线()部分为新添加的sbfd-UL-SubbandAllowed  IE。该示例中,sbfd-UL-SubbandAllowed IE的后缀r19表示在3GPP Rel-19引入。该IE也可能在3GPP的其他Release被引入,那么后缀就会有相应的变化,例如当在Rel-20引入时,后缀则为r20。在本示例的IE描述中,采用了前文所述的选项b和选项1。

仅当UL授权是配置授权时,此限制才适用。如果存在,则来自该逻辑信道的UL MAC sdu只能被映射到所指示的已配置授权配置。如果序列的大小为零,则来自该逻辑信道的UL MAC sdu不能被映射到任何配置的授权配置。如果该字段不存在,则来自该逻辑信道的UL MAC sdu可以被映射到任何配置的授权配置。如果字段configuredGrantType1Allowed存在,则仅允许该逻辑信道使用该序列中指示的那些配置的授权类型1配置;否则,该序列将不包括任何已配置的许可类型1配置。对应于TS 38.321[3]中规定的“允许的CG列表”。当SDT程序正在进行时,该字段被忽略。
allowedHARQ-mode
表示映射到此逻辑通道的HARQ进程允许的HARQ模式。如果该参数不存在,则映射的HARQ模式没有限制。该域适用于SRB1、SRB2和DRB。
sbfd-UL-SubbandAllowed
值true指示来自该逻辑信道的UL MAC sdu可以使用包括具有UL子带的任何SBFD符号的上行链路许可来传送。值false指示来自该逻辑信道的UL MAC sdu不能使用包括具有UL子带的任何SBFD符号的上行链路许可来传输。如果该字段不存在,则对于用于映射的SBFB UL子带没有限制。
当执行新的传输时,MAC实体应为满足以下所有条件的每个UL授权选择逻辑信道:
如果被配置,allowedSCS-List中的允许子载波间隔索引值的集合包括与UL授权相关联的子载波间隔索引;和
maxPUSCH-Duration,如果配置的话,大于或等于与UL授权相关联的PUSCH传输持续时间;和
configuredGrantType1Allowed,如果配置,在UL授权是配置的授权类型1的情况下设置为真;和
allowedServingCells(如果已配置)包括与UL授权相关的单元信息。不适用于与配置有相同MAC实体内的PDCP复制(即CA复制)的DRB相关联的逻辑信道;和
allowed CG-List(如果已配置)包括与UL授权相关联的已配置授权索引;和
allowedPHY-priority index,如果配置的话,包括与动态UL授权相关的优先级索引(如TS 38.213[6]第9条中所规定的);和
allowed harq-mode,如果配置的话,包括与UL授权相关联的HARQ进程的允许的UL HARQ模式;
如果配置了sbfd-UL-子带允许,则在UL授权包括具有UL子带的任何sbfd符号的情况下,sbfd--子带允许被设置为真。
综上所述,可选地,本公开提供一种在逻辑信道优先级处理时根据上行链路许可是否包含子带全双工的上行子带来选择逻辑信道的方法。在该方法中,网络通过RRC信令来配置每个逻辑信道是否能在子带全双工的上行子带来传输。对于每一个上行链路许可,如果资源包含子带全双工的上行子带,UE的MAC层根据RRC信令的配置来决定选择哪些逻辑信道继续进行逻辑信道优先级处理。具体来说就是在现有的逻辑信道选择步骤中,除了考虑已有的条件外,还需要额外考虑上行链路许可的资源是否包含子带全双工的上行子带。如果上行链路许可的资源包含子带全双工的上行子带并且RRC配置允许逻辑信道在子带全双工的上行子带来传输,那么该逻辑信道被选择继续进行后续的逻辑信道优先级处理流程。否则,该逻辑信道不被选择,从而不参与后续的逻辑信道优先级处理流程。
