Description

一种上行传输资源选择方法、终端和存储介质
本公开要求在2019年01月11日提交中国专利局、申请号为201910028755.5、申请名称为“一种上行传输资源选择方法、终端和存储介质”的中国专利申请的优先权,其全部内容通过引用结合在本公开中。
技术领域

背景技术
随着通信技术的不断发展,无线通信由第二代通信技术的语音交互转变为第五代通信技术的新空口(NR,New Radio)双连接通信方式。在时间敏感网络(TSN,Time Sensitive Networking)中,数据包在传输过程中具有固定的时延和传输周期,NR技术可以用来支持数据包传输具有确定性周期的网络业务。RAN1#95会议指出,对于服务小区的部分带宽(BWP,Bandwidth Part)资源,可以配置并激活多套资源配置信息,用以支持多种不用的业务或者通信类型,还可以增强数据传输的可靠性,减小数据传输的时延。
但是,在配置信息所对应的上行资源在时域上可能存在重叠或者部分重叠的情况,导致某些数据不能在当前的传输时隙进行发送,从而增加数据传输的时延。而对于一些时延要求比较高的业务,例如超高可靠低时延通信(URLLC,Ultra Reliable and Low Latency Communication)业务,则会出现不满足业务传输需求的问题。

根据下面参考附图对示例性实施例的详细说明,本公开的其它特征及方面将变得清楚。

具体实施方式
以下将参考附图详细说明本公开的各种示例性实施例、特征和方面。附图中相同的附图标记表示功能相同或相似的元件。尽管在附图中示出了实施例的各种方面,但是除非特别指出,不必按比例绘制附图。
在这里专用的词“示例性”意为“用作例子、实施例或说明性”。这里作为“示例性”所说明的任何实施例不必解释为优于或好于其它实施例。
另外,为了更好的说明本公开,在下文的具体实施方式中给出了众多的具体细节。本领域技术人员应当理解,没有某些具体细节,本公开同样可以实施。在一些实例中,对于本领域技术人员熟知的方法、手段、元件和电路未作详细描述,以便于凸显本公开的主旨。
在本公开实施例中,终端接收至少一个上行调度信息,根据上行调度信息,可以确定上行调度信息指示的上行链路资源的传输优先级,从而终端可以根据上行链路资源的 传输优先级,选择优先进行数据传输的上行链路资源。即使在配置信息所对应的上行链路资源在时域上存在重叠或者部分重叠的情况下,终端可以优先传输优先级高的数据,满足对时延要求比较高的业务数据传输需求。这里,上行调度信息可以包括半静态调度信息(configured grant)和动态调度信息(dynamic grant)。半静态调度信息可以用来支持数据传输周期确定的业务。通过本公开实施例,可以使用半静态调度信息调度周期确定业务的数据传输。
在相关技术中,当半静态调度信息所对应的上行链路资源与动态调度信息所对应的上行链路资源在时域上发生重叠或者部分重叠时,动态调度信息所对应的上行链路资源会覆盖半静态调度信息所对应的上行链路资源,若其中,动态调度信息所对应的上行链路资源用于传输优先级较低的业务数据,例如用于传输增强移动宽带(eMBB,enhance Mobile Broadband)业务数据,半静态调度信息所对应的上行链路资源用于传输优先级较高的业务数据,例如用于传输URLLC业务数据,那么在当前的时隙中传输eMBB业务数据,URLLC业务不能及时传输。但是URLLC业务通常情况下对时延的要求比较高,URLLC业务若不能及时传输,则会存在不满足业务传输需求的问题。本公开提供的上行传输资源选择方案,可以避免优先级高的业务数据由于传输不及时而导致的不满足业务传输需求的问题。
下面结合附图对本公开提供的上行传输资源选择方案进行详细说明。
图1示出根据本公开一实施例的上行传输资源选择方法的流程图。如图1所示,该上行传输资源选择方法包括:
步骤101,接收至少一个上行调度信息。
终端在与基站建立通信连接之后,可以接收基站发送的上行调度信息。这里的上行调度信息可以为一个或多个,一个上行调度信息可以指示一个上行链路资源。终端可以通过上行动态调度机制在基站发送的下行控制信息(DCI,Downlink Control Information)中获取上行调度信息,上行调度信息可以用于指示物理上行共享信道(PUSCH,Physical Uplink Shared Channel)的上行链路传输的资源配置,从而终端可以根据上行调度信息配置上行链路资源,通过DCI获取的上行调度信息可以称为动态调度信息。终端还可以在RRC信息中获取上行调度信息,通过无线资源控制(RRC,Radio Resource Control)信息获取的上行调度信息可以称为半静态调度信息,半静态调度信息可以用于支持数据传输周期确定的业务。半静态调度信息可以包括第一类半静态调度信息(Configured Grant Type1)和第二类半静态调度信息(Configured Grant Type2)。第一类半静态调度信息可以在RRC信息中获取,第二类半静态调度信息可以在RRC信息和/或DCI中获取。
步骤102,根据所述上行调度信息,确定所述上行调度信息指示的上行链路资源的传输优先级。
终端在获取至少一个上行调度信息之后,可以针对每个上行调度信息,根据该上行 调度信息中包括的资源分配信息,确定该上行调度信息所对应的上行链路资源,然后可以根据该上行调度信息确定上行链路资源的传输优先级。在终端接收多个上行调度信息的情况下,终端可以根据多个上行调度信息确定多个上行链路资源,每个上行调度信息可以指示一个上行链路资源,由于终端在同一个时域上对应一个上行链路资源,进而终端可以在多个上行链路资源中选择当前进行数据传输的上行链路资源,实现上行链路资源的优化配置。
步骤103,根据所述上行链路资源的传输优先级,选择进行数据传输的上行链路资源。
终端确定上行调度信息指示的上行链路资源的传输优先级之后,可以根据上行链路资源的传输优先级,选择进行数据传输的上行链路资源。需要说明的是,终端在选择进行数据传输的上行链路资源时,可以选择一个或者多个上行链路资源进行数据传输,在选择一个上行链路资源进行数据传输时,可以选择传输优先级最高的上行链路资源进行数据传输。选择进行数据传输的上行链路资源可以理解为由选择的上行链路资源进行数据传输,其他未被选择的上行链路资源不进行数据传输。或者,选择进行数据传输的上行链路资源还可以理解为由选择的上行链路资源传输进行数据传输,其他未被选择的上行链路资源可以分配给其他业务,这里不对具体的实施方式进行限制。
通过上述实施例提供的上行链路资源选择方法,终端可以确定上行调度信息指示的上行链路资源的传输优先级,从而上行链路资源在时域上存在重叠或者部分重叠的情况下,终端可以优先传输优先级高的数据,满足对时延要求比较高的业务数据传输需求。
基于此,本公开实施例还提供了确定上行链路资源的传输优先级的过程。
图2示出根据本公开一实施例的确定上行链路资源的传输优先级的流程图,包括:
步骤201,确定当前存在待传输数据的逻辑信道中优先级最高的目标逻辑信道。
步骤202,根据所述目标逻辑信道的传输格式配置参数和所述上行调度信息,确定所述上行调度信息指示的上行链路资源中匹配所述传输格式配置参数的上行链路资源。
步骤203,根据预设的资源选择条件,确定匹配所述传输格式配置参数的上行链路资源的传输优先级。
这里,当前存在待传输数据的逻辑信道(LCH,Logical CHannel)可以为一个或多个。当存在待传输数据的逻辑信道为多个时,终端可以在多个逻辑信道中选择优先级最高的逻辑信道作为目标逻辑信道。逻辑信道具有相应的传输格式配置参数,传输格式配置参数可以包括但不限于子载波间隔(SCS,SubCarrier Spacing)和物理上行共享信息持续时间(PUSCH-Duration,Physical Uplink Shared Channel Duration)。每个逻辑信道的传输格式配置参数可以为多个,例如,每个逻辑信道可以具有相应的SCS列表和最大PUSCH-Duration,在此范围内的传输格式配置参数均符合逻辑信道的要求。终端可以将目标逻辑信道的传输格式配置参数与一个或多个上行调度信息进行匹配,例如,终端将目标逻辑信道的SCS、PUSCH-Duration分别与每个上行调度信息中的SCS、 PUSCH-Duration进行对比,确定上行调度信息指示的上行链路资源中匹配目标逻辑信道的传输格式配置参数的一个或多个上行链路资源。
上述预设的资源选择条件,可以包括以下至少一项条件:上行链路资源的传输时延;上行链路资源的传输可靠性。在一种可能的实现方式中,上行链路资源的传输时延可以由PUSCH-Duration或者上行链路资源的结束时间进行表征。上行链路资源的传输可靠性可以由MCS索引值或者无线网络临时标识(RNTI,Radio Network Tempory Identity)的类型进行表征。
举例来说,在上行链路资源的传输时延越小的情况下,终端可以为上行链路资源设置的传输优先级越高,例如,可以为PUSCH-Duration最小或者上行链路资源的结束时间在先的上行链路资源设置最高的传输优先级。在上行链路资源的传输可靠性越高的情况下,终端可以为上行链路资源设置的传输优先级越高,例如,可以为MCS索引值最小或者使用调制与编码策略无线网络临时标识(Modulation and Coding Scheme RNTI,MCS-RNTI)或半静态调度无线网络临时标识(Configured Scheduling RNTI,CS-RNTI)加扰的上行调度信息所指示的上行链路资源设置最高的传输优先级。

在上行调度信息为动态调度信息的情况下,确定上行链路资源的传输优先级过程可以包括:
步骤301,根据所述上行调度信息携带的指示信息,确定所述指示信息指示的目标逻辑信道。
步骤302,根据所述目标逻辑信道的优先级,确定所述上行调度信息指示的上行链路资源的传输优先级。
这里,终端可以接收基站发送的多个上行调度信息,每个上行调度信息指示一个上行链路资源,多个上行调度信息对应多个上行链路资源。当任一上行调度信息为动态调度信息的情况下,终端可以根据该上行调度信息携带的指示信息,确定指示信息指示的一个或多个目标逻辑信道。指示信息可以是基站在向终端发送的上行调度信息中加入的指示信息,用于指示优先进行数据传输的逻辑信道。指示信息的bit位数本公开实施例不进行具体限制,指示信息的bit位数可以与指示信息指示的精度成正比,即指示的精度越高,指示信息的bit位数可以越多。例如,每个终端可以配置N个LCHs,N个LCHs可以按照优先级由高到低划分为M大类,则指示信息的bit位数可以为
Figure PCTCN2020071135-appb-000001
上取整。其中,N是M的整数倍,N与M为正整数。
终端在确定上行调度信息指示的上行链路资源的传输优先级时,可以将目标逻辑信道的优先级作为上行调度信息指示的上行链路资源的传输优先级。
在上行调度信息为半静态调度信息的情况下,确定上行链路资源的传输优先级过程可以包括:
步骤311,根据逻辑信道的传输格式配置参数和所述上行调度信息,确定所述逻辑信道中所述传输格式配置参数匹配所述上行调度信息的第一逻辑信道。
步骤312,根据所述上行调度信息与所述第一逻辑信道的业务传输模式,确定所述第一逻辑信道中所述业务传输模式匹配所述上行调度信息的目标逻辑信道。
步骤313,根据所述目标逻辑信道的优先级,确定所述上行调度信息指示的上行链路资源的传输优先级。
在一种可能的实现方式中,终端在确定逻辑信道中传输格式配置参数匹配上行调度信息的第一逻辑信道时,在上行调度信息为第一类半静态调度信息的情况下,终端可以在基站发送的RRC配置信息中获取上行调度信息指示的上行链路资源的传输格式配置参数,然后根据逻辑信道的传输格式配置参数和上行链路资源的传输格式配置参数,确定逻辑信道中逻辑信道的传输格式配置参数匹配上行链路资源的传输格式配置参数的第一逻辑信道。
在一种可能的实现方式中,终端在确定逻辑信道中所述传输格式配置参数匹配上行调度信息的第一逻辑信道时,在上行调度信息为第二类半静态调度信息的情况下,终端可以在基站发送的RRC配置信息以及下行控制信息DCI激活信令中,获取上行链路资源的传输格式配置参数。或者,终端在基站发送的DCI激活信令中,获取所述上行链路资源的传输格式配置参数,然后根据所述逻辑信道的传输格式配置参数和上行链路资源的传输格式配置参数,确定逻辑信道中逻辑信道的传输格式配置参数匹配上行链路资源的传输格式配置参数的第一逻辑信道。
这里,终端可以将逻辑信道的传输格式配置参数与上行调度信息中的传输格式配置参数进行匹配,确定逻辑信道中传输格式配置参数匹配上行调度信息的第一逻辑信道。传输格式配置参数可以包括SCS和PUSCH-Duration。逻辑信道还可以具有业务传输模式,业务传输模式可以包括业务数据的固定偏移量(fixed offset)、业务数据的周期(period)、业务数据的数据包大小(packet size)。数据包大小可以理解为数据包在每个周期或一次性到达终端的数据量。相应地,上行调度信息可以包括上行链路资源的传输模式,传输模式可以包括fixed offset、period、packet size。终端可以将上行调度信息中的传输模式与第一逻辑信道的业务传输模式进行匹配,在第一逻辑信道中确定业务传输模式匹配上行调度信息中的传输模式的一个或者多个目标逻辑信道。然后可以将目标逻辑信道的优先级确定为相应的上行链路资源的传输优先级。
在一种可能的实现方式中,终端在根据上行链路资源的传输优先级,选择进行数据传输的上行链路资源时,可以在目标逻辑信道存在待传输数据的上行链路资源中,选择传输优先级最高的上行链路资源进行数据传输。在多个上行调度信息包括半静态调度信息和/或动态调度信息的情况下,终端可以在目标逻辑信道存在待传输数据时,将存在待传输数据目标逻辑信道的优先级作为目标逻辑信道对应的上行链路资源的传输优先级, 然后从中选择传输优先级最高的上行链路资源进行数据传输。
图4示出根据本公开一实施例的确定上行链路资源的传输优先级的流程图,包括:
步骤401,根据所述上行调度信息,确定所述上行链路资源的传输优先级信息;
步骤402,根据所述传输优先级信息,确定所述上行调度信息指示的上行链路资源的传输优先级。
这里,终端可以在上行调度信息中获取传输优先级信息。传输优先级信息可以是基站在向终端发送的上行调度信息中加入的,用于指示上行调度信息指示的上行链路资源的传输优先级信息。终端可以根据传输优先级信息确定上行链路资源的传输优先级。传输优先级信息bit位数本公开实施例不进行具体限制,传输优先级信息的bit位数可以与传输优先级信息指示的传输优先级的精度成正比,即指示的传输优先级精度越高,传输优先级信息的bit位数可以越多。例如,传输优先级可以为N个,则传输优先级信息的bit位数可以为
Figure PCTCN2020071135-appb-000002
上取整。其中,N是正整数。
在一种可能的实施方式中,在上行调度信息为动态调度信息的情况下,终端可以在基站发送的下行控制信息DCI激活信令中,获取所述上行链路资源的传输优先级信息。
在一种可能的实施方式中,在上行调度信息为第一类半静态调度信息的情况下,终端可以在基站发送的RRC配置信息中,获取上行链路资源的传输优先级信息。在上行调度信息为第二类半静态调度信息的情况下,终端可以在基站发送的RRC配置信息中,获取上行链路资源的传输优先级信息。或者,终端可以在基站发送的DCI激活信令中,获取上行链路资源的传输优先级信息。
图5示出根据本公开一实施例的确定上行链路资源的传输优先级的流程图,包括:
步骤501,获取对所述上行调度信息加扰的无线网络临时标识RNTI。
步骤502,根据所述RNTI的类型,确定所述上行调度信息指示的上行链路资源的传输优先级。
这里,RNTI可以包括:小区无线网络临时标识(C-RNTI,Cell-RNTI);CS-RNTI;MCS-RNTI。相应地,RNTI所指示的传输优先级由高到低的顺序是:MCS-RNTI;CS-RNTI;C-RNTI。不同类型的RNTI可以指示不同的数据传输可靠性,数据传输可靠性高的上行链路资源可以传输对可靠性要求较高的业务数据,因此,终端可以根据RNTI的类型确定上行调度信息指示的上行链路资源的传输优先级,并选择数据优先级最高的上行链路资源进行数据传输。
这样,通过上述上行链路资源选择方案,终端可以根据上行链路资源的传输优先级,选择优先进行数据传输的上行链路资源。即使在上行调度信息所对应的上行链路资源在时域上存在重叠或者部分重叠的情况下,终端可以优先传输优先级高的数据,满足对时延要求比较高的业务数据传输需求。
