本公开的实施例提供的技术方案可以包括以下有益效果:
通过用于传输控制PDU的逻辑信道将控制PDU发送给MAC实体,使得MAC实体确定为逻辑信道提升的优先级,根据优先级发送控制PDU,由于逻辑信道的优先级被提升了,因此,MAC实体会优先发送控制PDU,而不是按照相关技术中为逻辑信道分配固定的优先级,在优先级较高的逻辑信道中的数据PDU发送完后,再发送优先级较低的逻辑信道中的控制PDU,可以缩短控制PDU的发送时延。
通过为控制PDU设置用于指示控制PDU所属的数据承载的承载标识,由于控制PDU需要由其所属的数据承载对应的RLC实体处理,因此,当在专用逻辑信道上发送多个控制PDU时,可以根据承载标识确定处理各个控制PDU的RLC实体,从而保证控制PDU能够被成功处理。
通过第一指示信息指示是否在专用逻辑信道上发送控制PDU,这样,当某 些控制PDU对时延要求不高时,可以不在专用逻辑信道上发送控制PDU,而是在普通的逻辑信道上发送控制PDU,从而保证对时延要求高的控制PDU被优先发送。
通过RLC实体向MAC实体发送控制PDU的数据量,由于MAC实体能够根据数据量确定为控制PDU分配的资源块的大小,因此,MAC实体可以为控制PDU分配足够多的资源块来发送控制PDU。
应当理解的是,以上的一般描述和后文的细节描述仅是示例性的,并不能限制本公开。

在步骤201中,建立用于传输控制PDU的专用承载。
在步骤202中,当存在待发送的控制PDU时,通过通信设备的RLC实体在专用承载对应的逻辑信道上将控制PDU发送给通信设备的MAC实体。
在步骤203中,通过MAC实体根据逻辑信道被提升的优先级发送控制PDU。
综上所述,本公开提供的控制PDU发送方法,通过用于传输控制PDU的逻辑信道将控制PDU发送给MAC实体,使得MAC实体确定为逻辑信道提升的优先级,根据优先级发送控制PDU,由于逻辑信道的优先级被提升了,因此,MAC实体会优先发送控制PDU,而不是按照相关技术中为逻辑信道分配固定的优先级,在优先级较高的逻辑信道中的数据PDU发送完后,再发送优先级较低的逻辑信道中的控制PDU,可以缩短控制PDU的发送时延。
本公开提供了两种提升发送控制PDU的优先级的方案,第一种方案是为控制PDU建立专用逻辑通道,详见图3所示的实施例中的描述;第二种方案是优先调度发送控制PDU的逻辑信道,详见图4所示的实施例中的描述。
图3是根据另一示例性实施例示出的一种控制PDU发送方法的流程图,该控制PDU发送方法应用于通信设备中,如图3所示,该控制PDU发送方法包括如下步骤。
在步骤301中,建立用于传输控制PDU的专用承载,专用承载对应的逻辑信道是只用于传输控制PDU的专用逻辑信道。
其中,控制PDU中可以携带RLC状态报告,也可以携带其他信息,本实 施例不限定控制PDU的用途。
逻辑信道是通信设备中RLC实体和MAC实体之间的数据传输通道,且一条逻辑信道与一个承载对应。其中,承载包括信令承载和数据承载,信令承载用于传输控制面的信令;数据承载用于传输用户面的数据。
专用逻辑信道只用于传输控制PDU,不传输数据PDU。其中,专用逻辑信道可以是对应于数据承载的逻辑信道,也可以是对应于信令承载的逻辑信道。即,数据承载对应于一条专用逻辑信道,且该专用逻辑信道只用于传输用户面的控制PDU;信令承载对应于一条专用逻辑信道,且该专用逻辑信道只用于传输控制面的控制PDU。
由于信令承载对应的逻辑信道的优先级一般高于数据承载对应的逻辑信道的优先级,且信令承载所对应的逻辑信道中传输的数据量并不大,因此,通过信令承载对应的逻辑信道发送控制PDU时,该控制PDU的发送时延并不会太大。所以,在信令承载对应的逻辑信道上发送控制PDU时,无需为控制PDU设置专用逻辑信道,即,控制PDU与数据PDU可以共用相同的逻辑信道。
通信设备需要先建立专用承载,再对专用承载进行配置。在第一种实现方式中,当通信设备是基站时,生成并发送用于配置专用承载的承载配置信息,承载配置信息用于指示UE配置专用承载。在第二种实现方式中,当通信设备是UE时,接收基站生成并发送的专用承载的承载配置信息,根据承载配置信息配置专用承载。
在实现时,基站根据生成的承载配置信息配置建立的专用承载,并将承载配置信息发送给UE,UE根据承载配置信息配置建立的专用承载,在配置完成后,基站和UE可以在利用专用承载传输控制PDU。可选的,承载配置信息还可以写入标准,基站和UE在执行标准时分别根据承载配置信息配置专用承载,在配置完成后,基站和UE可以利用专用承载传输控制PDU。
本实施例中,专用承载的承载配置信息包括RLC实体配置信息和逻辑信道配置信息,RLC实体配置信息包括AM配置信息,且不包括PDCP配置信息;逻辑信道配置信息包括第一优先级信息,第一优先级信息用于指示专用逻辑信道被提升后的优先级。
RLC实体配置信息用于配置RLC实体,逻辑信道配置信息用于配置专用逻辑信道。
由于专用逻辑信道只传输控制PDU,因此,RLC实体配置信息需要包括 用于配置AM的AM配置信息,而并不需要包括用于配置PDCP实体的PDCP配置信息,PDCP实体与RLC实体之间传输的是数据PDU。
当通过优先级数值来指示优先级时,第一优先级信息可以是优先级数值区间,使得通信设备在该优先级数值区间中灵活选择优先级数值进行配置。比如,当优先级数值区间为[0,6]时,第一优先级信息可以是[0,6]。其中,优先级数值越低,优先级越高。
然而,由于通信设备并不确定信令承载对应的逻辑信道以及数据承载对应的用于传输数据PDU的逻辑信道的优先级,因此,为了能够尽可能提升专用逻辑信道的优先级,可以将第一优先级信息设置成最低的优先级数值,以指示专用逻辑信道的优先级最高。
当然,在明确了信令承载对应的逻辑信道以及数据承载对应的用于传输数据PDU的逻辑信道的优先级时,还可以根据这些优先级的优先级数值设置第一优先级信息。比如,将第一优先级信息设置成高于信令承载对应的逻辑信道的优先级数值,且低于用于传输数据PDU的逻辑信道的优先级数值的优先级数值,以指示所述专用逻辑信道的优先级低于信令承载对应的逻辑信道的优先级,且高于用于传输数据PDU的逻辑信道的优先级,本实施例不对第一优先级信息的设置方式作限定。
需要说明的是,第一优先级信息可以位于逻辑信道配置信息中,此时的承载配置信息如上所示。在其他的实现方式中,第一优先级信息可以位于RLC实体配置信息中,也可以预存在通信设备中,此时的承载配置信息如下所示。
本实施例中,专用承载的承载配置信息包括RLC实体配置信息,RLC实体配置信息包括AM配置信息和第一优先级信息,且不包括PDCP配置信息;或,RLC实体配置信息包括AM配置信息,不包括PDCP配置信息和第一优先级信息,且第一优先级信息预存在通信设备中,第一优先级信息用于指示专用逻辑信道被提升后的优先级。
在这种实现方式中,承载配置信息还可以包括逻辑信道配置信息,此时的逻辑信道配置信息与相关技术中的逻辑信道配置信息相同,此处不再赘述。
可选的,逻辑信道配置信息还可以包括信道标识,信道标识用于在RLC实体与MAC实体之间标识专用逻辑信道。比如,RLC实体在专用逻辑信道上向MAC实体发送信息时,可以在信息中携带专用逻辑信道的信道标识,MAC实体能够根据该信道标识识别出专用逻辑信道。
可选的,逻辑信道配置信息还可以包括是否启用专用逻辑信道的信息。这是因为,对于某些业务来说,业务的时延要求并不高,因此,无需优先发送控制PDU,此时可以不启用专用逻辑信道。
在步骤302中,当存在待发送的控制PDU时,为控制PDU设置用于指示控制PDU所属的数据承载的承载标识。
控制PDU只能由其所属的数据承载对应的RLC实体处理,且每个RLC实体与数据承载之间具有对应关系,相关技术中,由于发送控制PDU的逻辑信道唯一对应于一个数据承载,因此,接收方可以根据传输控制PDU的逻辑信道所对应的数据承载来确定对应的RLC实体。本实施例中,由于所有的控制PDU都通过专用逻辑信道传输,接收方无法确定专用逻辑信道所对应的数据承载,因此,需要为控制PDU设置用于指示控制PDU所属的数据承载的承载标识,从而根据该承载标识来确定处理各个控制PDU的RLC实体,从而保证控制PDU能够被成功处理。本实施例不限定承载标识在控制PDU中的位置。
可选的,控制PDU所属的数据承载的承载配置信息包括第一指示信息,第一指示信息用于指示是否在专用逻辑信道上发送控制PDU。这样,当某些控制PDU对时延要求不高时,可以不在专用逻辑信道上发送控制PDU,而是在普通的逻辑信道上发送控制PDU,从而保证对时延要求高的控制PDU被优先发送。
在步骤303中,通过通信设备的RLC实体在专用承载对应的专用逻辑信道上将控制PDU发送给通信设备的MAC实体。
在配置完专用承载和生成控制PDU之后,通信设备可以利用专用承载来发送控制PDU。在发送过程中,RLC实体在确定控制PDU被触发,即,存在待发送的控制PDU时,计算该控制PDU的数据量,并将该数据量发送给MAC实体;MAC实体确定专用逻辑信道被提升后的优先级,根据优先级为控制PDU分配资源块,并将资源块的大小发送给RLC实体;RLC实体根据资源块的大小,在专用逻辑信道上将控制PDU发送给MAC实体。
在计算控制PDU的数据量时,若只存在一个控制PDU,则RLC实体直接计算该控制PDU的数据量,并将得到的数据量发送给MAC实体。若待发送的控制PDU的数量为n且n≥2,则RLC实体计算每个控制PDU的数据量;将得到的n个控制PDU的数据量相加的和作为数据量。其中,计算控制PDU的数据量的技术已经非常成熟,此处不作赘述。比如,n为3,且第一个待发送的 控制PDU的数据量是50bit,第二个待发送控制PDU的数据量是60bit,第三个待发送的控制PDU的数量是80bit,则RLC计算得到的数据量是50+60+80=190bit,将190bit作为数据量发送给MAC实体。
通信设备可以在一条专用逻辑信道上同时发送多个控制PDU,从而提高控制PDU的发送效率。
MAC实体根据第一优先级信息确定出专用逻辑信道的优先级。可选的,除了优先级,MAC实体还可以根据QoS等其他参数来为控制PDU分配资源块。
需要说明的是,当MAC实体分配的资源块较小时,即使RLC实体计算了n个控制PDU的数据量,RLC实体仍然只能传输其中的部分控制PDU,并在专用逻辑信道上将这部分控制PDU发送给MAC实体。比如,存在5个待发送的控制PDU,且MAC实体分配的资源只能够发送3个控制PDU,此时,RLC实体根据这5个控制PDU被触发的顺序,在专用逻辑信道上将前3个被触发的控制PDU发送给MAC实体。
在步骤304中,通过MAC实体根据专用逻辑信道被提升的优先级发送控制PDU。
综上所述,本公开提供的控制PDU发送方法,通过用于传输控制PDU的逻辑信道将控制PDU发送给MAC实体,使得MAC实体确定为逻辑信道提升的优先级,根据优先级发送控制PDU,由于逻辑信道的优先级被提升了,因此,MAC实体会优先发送控制PDU,而不是按照相关技术中为逻辑信道分配固定的优先级,在优先级较高的逻辑信道中的数据PDU发送完后,再发送优先级较低的逻辑信道中的控制PDU,可以缩短控制PDU的发送时延。
通过为控制PDU设置用于指示控制PDU所属的数据承载的承载标识,由于控制PDU需要由其所属的数据承载对应的RLC实体处理,因此,当在专用逻辑信道上发送多个控制PDU时,可以根据承载标识确定处理各个控制PDU的RLC实体,从而保证控制PDU能够被成功处理。
通过第一指示信息指示是否在专用逻辑信道上发送控制PDU,这样,当某些控制PDU对时延要求不高时,可以不在专用逻辑信道上发送控制PDU,而是在普通的逻辑信道上发送控制PDU,从而保证对时延要求高的控制PDU被优先发送。
图4是根据另一示例性实施例示出的一种控制PDU发送方法的流程图, 该控制PDU发送方法应用于通信设备中,如图4所示,该控制PDU发送方法包括如下步骤。
在步骤401中,建立用于传输控制PDU的专用承载,专用承载是在对应的逻辑信道上发送控制PDU时被优先调度的承载。
其中,控制PDU中可以携带RLC状态报告,也可以携带其他信息,本实施例不限定控制PDU的用途。
逻辑信道是通信设备中RLC实体和MAC实体之间的数据传输通道,且一条逻辑信道与一个承载对应。其中,承载包括信令承载和数据承载,信令承载用于传输控制面的信令;数据承载用于传输用户面的数据。
本实施例中,专用承载是在对应的逻辑信道上发送控制PDU时被优先调度的承载。即,在专用承载对应的逻辑信道上发送的数据是控制PDU时,提升该逻辑信道的优先级;在专用承载对应的逻辑信道上发送的数据不是控制PDU时,不提升该逻辑信道的优先级,按照该逻辑信道原先的优先级进行调度。专用承载可以是信令承载,也可以是数据承载,本实施例不作限定。
通信设备需要先建立专用承载,再对专用承载进行配置。在第一种实现方式中,当通信设备是基站时,生成并发送用于配置专用承载的承载配置信息,承载配置信息用于指示UE配置专用承载。在第二种实现方式中,当通信设备是UE时,接收基站生成并发送的专用承载的承载配置信息,根据承载配置信息配置专用承载。
在实现时,基站根据生成的承载配置信息配置建立的专用承载,并将承载配置信息发送给UE,UE根据承载配置信息配置建立的专用承载,在配置完成后,基站和UE可以在利用专用承载传输控制PDU。可选的,承载配置信息还可以写入标准,基站和UE在执行标准时分别根据承载配置信息配置专用承载,在配置完成后,基站和UE可以利用专用承载传输控制PDU。
本实施例中,专用承载的承载配置信息包括RLC实体配置信息和逻辑信道配置信息,RLC实体配置信息包括AM配置信息;逻辑信道配置信息包括第三指示信息和第二优先级信息;或,逻辑信道配置信息包括第三指示信息,不包括第二优先级信息,且第二优先级信息预存在通信设备中。其中,第三指示信息用于指示承载在对应的逻辑信道上发送控制PDU时被优先调度,第二优先级信息用于指示逻辑信道被提升后的优先级。
RLC实体配置信息用于配置RLC实体,逻辑信道配置信息用于配置逻辑 信道。
当承载配置信息中包括第三指示信息时,确定承载配置信息所配置的承载是专用承载;当承载配置信息中不包括第三指示信息时,确定承载配置信息所配置的承载不是专用承载。
第二优先级信息用于指示逻辑信道被提升后的优先级。其中,第二优先级信息与第一优先级信息相同,详见步骤301中对第一优先级信息的描述,此处不再赘述。
需要说明的是,第三指示信息可以位于逻辑信道配置信息中,且第二优先级信息可以位于逻辑信道配置信息中,也可以预存在通信设备中,此时的承载配置信息如上所示。在其他的实现方式中,第三指示信息可以位于RLC实体配置信息中,且第二优先级信息可以位于RLC实体配置信息中,也可以预存在通信设备中,此时的承载配置信息如下所示。
本实施例中,专用承载的承载配置信息包括RLC实体配置信息,RLC实体配置信息包括AM配置信息、第三指示信息和第二优先级信息;或,RLC实体配置信息包括AM配置信息和第三指示信息,不包括第二优先级信息,且第二优先级信息预存在通信设备中。其中,第三指示信息用于指示承载在对应的逻辑信道上发送控制PDU时被优先调度,第二优先级信息用于指示逻辑信道被提升后的优先级。
可选的,承载配置信息还可以包括专用承载的承载标识。其中,承载标识用于标识专用承载。
可选的,逻辑信道配置信息还可以包括信道标识,信道标识用于在RLC实体与MAC实体之间标识逻辑信道。
在步骤402中,当存在待发送的控制PDU时,通过通信设备的RLC实体在专用承载对应的逻辑信道上将控制PDU发送给通信设备的MAC实体。
在配置完专用承载之后,通信设备可以利用专用承载来发送数据。由于在专用承载对应的逻辑信道上发送的数据是控制PDU时,提升该逻辑信道的优先级;在专用承载对应的逻辑信道上发送的数据不是控制PDU时,不提升该逻辑信道的优先级,按照该逻辑信道原先的优先级进行调度,因此,为了使MAC实体确定是否需要提升该逻辑信道的优先级,当RLC实体向MAC实体发送包括控制PDU的数据时,还需要向MAC实体发送第二指示信息,第二指示信息用于指示逻辑信道上将要发送控制PDU;当RLC实体向MAC实体发 送不包括控制PDU的数据时,不需要向MAC实体发送第二指示信息。
当待发送的数据包括控制PDU时,RLC实体计算该数据的数据量,并将该数据的数据量和第二指示信息发送给MAC实体;MAC实体根据第二指示信息确定逻辑信道被提升后的优先级,根据优先级和数据的数据量为控制PDU分配资源块,并将资源块的大小发送给RLC实体;RLC实体根据资源块的大小,在逻辑信道上将控制PDU发送给MAC实体。
可选的,除了优先级,MAC实体还可以根据QoS等其他参数来为控制PDU分配资源块。
在步骤403中,通过RLC实体向MAC实体发送控制PDU的数据量,数据量用于供MAC实体确定为控制PDU分配的资源块的大小。
由于待发送的数据可能同时包括控制PDU和数据PDU,当MAC实体可分配的资源块不多时,MAC实体可以本次先发送控制PDU,下次再发送数据PDU,因此,为了能够保证控制PDU被发送出去,RLC实体还可以将控制PDU的数据量发送给MAC实体,这样,MAC实体可以为控制PDU分配足够多的资源块来发送控制PDU。
需要说明的是,本实施例并不限定待发送数据的数据量、第二指示信息和控制PDU的数据量的发送顺序。可选的,RLC实体可以同时发送待发送数据的数据量、第二指示信息和控制PDU的数据量。
在步骤404中,通过MAC实体根据逻辑信道被提升的优先级发送控制PDU。
需要说明的是,当在多个专用承载对应的逻辑信道上发送控制PDU时,MAC实体可以按照这多个逻辑信道的优先级来为各个控制PDU分配资源块,并按照资源块来发送各个控制PDU。
综上所述,本公开提供的控制PDU发送方法,通过用于传输控制PDU的逻辑信道将控制PDU发送给MAC实体,使得MAC实体确定为逻辑信道提升的优先级,根据优先级发送控制PDU,由于逻辑信道的优先级被提升了,因此,MAC实体会优先发送控制PDU,而不是按照相关技术中为逻辑信道分配固定的优先级,在优先级较高的逻辑信道中的数据PDU发送完后,再发送优先级较低的逻辑信道中的控制PDU,可以缩短控制PDU的发送时延。
通过RLC实体向MAC实体发送控制PDU的数据量,由于MAC实体能够根据数据量确定为控制PDU分配的资源块的大小,因此,MAC实体可以为 控制PDU分配足够多的资源块来发送控制PDU。
