Description

上行调度请求的发送方法、装置、设备及存储介质 技术领域
本公开涉及无线通信技术领域,尤其涉及一种上行调度请求的发送方法、装置、设备及存储介质。
背景技术
在5G NR(英文:New Radio Access Technology)通信系统中,可以将一个载波划分为多个带宽部分(英文:Bandwidth Part;简称:BWP),其中,一个用户设备(英文:User Equipment;简称:UE)同一时刻在一个载波上只能有一个激活BWP,UE通常可以优先在该激活BWP上进行数据传输。当UE中的某一逻辑信道中存在需要向基站发送的上行通信数据时,UE可以通过服务小区(英文:Serving cell)中的激活BWP向基站发送上行调度请求(英文:Scheduling Request;简称:SR),以利用该SR向基站请求用于传输该上行通信数据的上行资源。然而,在实际应用中,很可能会出现服务小区中的激活BWP上不存在物理上行控制信道(英文:Physical Uplink Control Channel;简称:PUCCH)的资源的情况,此时,UE就无法通过服务小区中的激活BWP向基站发送SR。
相关技术中,在服务小区中的激活BWP上不存在PUCCH的资源的情况下,UE可以在特殊小区(英文:special cell)的激活BWP上向基站发送随机接入请求,以进行随机接入,如果特殊小区的激活BWP上不存在物理随机接入信道(英文:Physical Random Access Channel;简称:PRACH)的资源时,UE可以转而在特殊小区的非激活BWP上向基站发送随机接入请求,以进行随机接入。在进行随机接入后,UE可以向基站请求用于传输上行通信数据的上 行资源。
然而,随机接入通常需要基站和UE进行四次交互才能完成,耗时较长,而且存在随机接入失败的风险,因此,相关技术中,UE向基站请求上行资源的效率较低。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开实施方式作进一步地详细描述。
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在无线通信系统中,当用户设备(英文:User Equipment;简称:UE)中的某一逻辑信道存在需要向基站发送的上行通信数据时,就可以触发UE向基站发送上行调度请求(英文:Scheduling Request;简称:SR)。通常情况下, UE可以通过物理上行控制信道(英文:Physical Uplink Control Channel;简称:PUCCH)向基站发送该SR,基站在接收到UE发送的SR后,可以根据该SR以及基站与UE的进一步交互为UE分配用于传输该上行通信数据的上行资源。
在5G NR(英文:New Radio Access Technology)通信系统中,一个载波可以分为多个带宽部分(英文:Bandwidth Part;简称:BWP),UE可以优先通过激活的BWP进行上行传输。
相关技术中,在5G NR通信系统中,向基站发送SR的过程中,UE可以确定服务小区(英文:Serving cell)中的激活BWP上是否配置有PUCCH资源,若配置有PUCCH资源,UE就可以通过该PUCCH资源向基站发送SR,以向基站请求用于发送上行通信数据的上行资源,若没有配置PUCCH资源,UE就需要进行随机接入,以在随机接入后向基站请求用于发送上行通信数据的上行资源。
可选的,在UE进行随机接入时,UE可以先确定特殊小区(英文:special cell)中的激活BWP上是否配置有物理随机接入信道(英文:Physical Random Access Channel;简称:PRACH)资源,若配置有PRACH资源,UE就可以通过该PRACH资源向基站发送随机接入请求,若没有配置PRACH资源,UE就需要继续确定特殊小区中的未激活BWP(例如,初始BWP)上是否配置有PRACH资源,若未激活BWP上配置有PRACH资源,则UE就可以通过该PRACH资源向基站发送随机接入请求。
由上述说明可知,在5G NR通信系统中,UE向基站请求上行资源的过程中,也即是UE向基站发送SR的过程中,UE需要进行随机接入的概率较高。而随机接入通常需要基站和UE进行四次交互才能完成,耗时较长,同时随机接入还存在着一定的失败风险,因此,相关技术中,UE向基站请求上行资源的效率较低。
本公开实施例提供了一种上行调度请求的发送方法,可以提高UE向基站请求上行资源的效率。
在该上行调度请求的发送方法中,UE可以在第一激活BWP上不存在用于传输SR的位于PUCCH上的第一上行资源时,确定n个未激活BWP中的每个未激活BWP上是否存在用于传输SR的位于PUCCH上的第二上行资源,并在第一未激活BWP上存在第二上行资源时,通过该第二上行资源向基站发送SR,其中,第一未激活BWP是n个未激活BWP中的BWP,这样,在UE无法通过第一激活BWP向基站发送SR的情况下,UE可以尝试通过未激活BWP向基站发送SR,因此可以在一定程度上减小UE向基站请求上行资源的过程中UE需要进行随机接入的概率,从而可以提高UE向基站请求上行资源的效率。
下面,将对本公开实施例提供的上行调度请求的发送方法所涉及到的实施环境进行说明。
图1为本公开实施例提供的上行调度请求的发送方法所涉及到的实施环境的示意图。如图1所示,该实施环境可以包括基站10和UE 20。基站10和UE20可以通过通信网络进行连接,UE 20为基站10所服务的小区中的任一个UE。
其中,上述通信网络可以为5G NR通信网络,或者,其他的与5G NR通信网络类似的通信网络。
图2是根据一示例性实施例示出的一种上行调度请求的发送方法的流程图,该上行调度请求的发送方法可以用于图1所示的UE 20中,如图2所示,该上行调度请求的发送方法包括以下步骤:
步骤201、在发送SR时,UE确定第一激活BWP上是否存在用于发送SR的第一上行资源。
其中,该第一上行资源位于PUCCH上。
步骤202、当第一激活BWP上不存在第一上行资源时,UE确定n个未激活BWP中的每个未激活BWP上是否存在用于发送该SR的第二上行资源。
其中,该第二上行资源位于PUCCH上,n为正整数。
步骤203、当第一未激活BWP上存在第二上行资源时,UE通过第一未激活BWP上的第二上行资源向基站发送该SR。
其中,第一未激活BWP为上述n个未激活BWP中的BWP。
综上所述,本公开实施例提供的上行调度请求的发送方法,通过在第一激活BWP上不存在用于传输SR的位于PUCCH上的第一上行资源时,确定n个未激活BWP中的每个未激活BWP上是否存在用于传输SR的位于PUCCH上的第二上行资源,并在第一未激活BWP上存在第二上行资源时,通过该第二上行资源向基站发送SR,其中,第一未激活BWP是n个未激活BWP中的BWP,这样,在UE无法通过第一激活BWP向基站发送SR的情况下,UE可以尝试通过未激活BWP向基站发送SR,因此可以在一定程度上减小UE向基站请求上行资源的过程中UE需要进行随机接入的概率,从而可以提高UE向基站请求上行资源的效率。
图3是根据一示例性实施例示出的一种上行调度请求的发送方法的流程图,该上行调度请求的发送方法可以用于图1所示的实施环境中,如图3所示,该上行调度请求的发送方法包括以下步骤:
步骤301、在发送SR时,UE确定第一激活BWP上是否存在用于发送SR的第一上行资源。
其中,该SR可以是由UE的目标逻辑信道中的上行通信数据所触发的;该第一激活BWP可以是服务小区中的激活BWP,也可以是特殊小区中的激活BWP,该第一激活BWP满足目标逻辑信道的LCP;该第一上行资源位于PUCCH上。
这里的LCP是logical channel prioritization(中文:逻辑信道优先分配流程)的缩写。
通常情况下,不同的逻辑信道对用于传输该逻辑信道的上行通信数据的上行资源都有一定的要求,这些要求可以用逻辑信道的LCP来进行表征,例如, LCP可以包括对上行资源的子载波间隔的要求和对上行资源的物理上行共享信道(英文:Physical Uplink Shared Channel;简称:PUSCH)的要求等。只有满足某一逻辑信道的LCP的上行资源才能用于传输该逻辑信道的上行通信数据。在步骤301中,用于发送SR的第一激活BWP可以满足目标逻辑信道的LCP。
若UE确定第一激活BWP上存在第一上行资源,则UE可以通过该第一上行资源向基站发送SR。若UE确定第一激活BWP上并不存在该第一上行资源,则UE可以执行步骤302的技术过程。
步骤302、当第一激活BWP上不存在第一上行资源时,UE确定n个未激活BWP中的每个未激活BWP上是否存在用于发送SR的第二上行资源。
其中,该第二上行资源位于PUCCH上;n为正整数,该n个未激活BWP可以均为服务小区中的未激活BWP,也可以均为特殊小区中的未激活BWP,或者,可以既包括服务小区中的非激活BWP又包括特殊小区中的未激活BWP;在n为1的情况下,步骤302中的n个未激活BWP可以为特殊小区中的初始BWP;该n个未激活BWP可以位于激活载波上,其中,该激活载波满足目标逻辑信道的LCP。
在本公开实施例中,当第一激活BWP上不存在第一上行资源时,UE可以不立即进行随机接入,而是确定n个未激活BWP中是否存在第二上行资源,以尝试通过未激活BWP向基站发送SR,这就可以减小UE在向基站请求上行通信资源时需要进行随机接入的概率,从而提高了UE向基站请求上行通信资源的效率。
可选的,在本公开实施例中,UE可以逐一确定该n个未激活BWP中的每个未激活BWP上是否存在第二上行资源,当某一未激活BWP上存在第二上行资源时,UE可以停止确定其他的未激活BWP上是否存在第二上行资源。
在一种可能的实现方式中,UE确定n个未激活BWP中的每个未激活BWP上是否存在第二上行资源之前,还可以确定该n个未激活BWP中的每个未激 活BWP上是否存在用于发送上行通信数据的第三上行资源,其中,第三上行资源可以用于传输上行通信数据。
在n个未激活BWP中存在第三上行资源的情况下,UE可以不需要向基站请求上行资源,也即是,UE可以不需要向基站发送SR,或者进行随机接入,而是可以直接通过该n个未激活BWP上存在的第三上行资源向基站发送上述目标逻辑信道中的上行通信数据,这样,UE不需要进行随机接入或者向基站发送SR,就能够实现上行通信数据的传输。因此,UE在确定未激活BWP上是否存在第二上行资源之前,还可以确定未激活BWP上是否存在第三上行资源。
确定每一未激活BWP上均不存在第三上行资源时,UE可以执行确定未激活BWP上是否存在第二上行资源的技术过程。
在确定该n个未激活BWP中的某一个未激活BWP(以下称为第三未激活BWP)上存在第三上行资源,且,第三未激活BWP上的第三上行资源满足目标逻辑信道的LCP时,UE可以通过第三未激活BWP上的第三上行资源发送目标逻辑信道中的上行通信数据,在通过第三未激活BWP上的第三上行资源发送目标逻辑信道中的上行通信数据后,UE可以退出流程。
在确定该n个未激活BWP中的未激活BWP上存在第三上行资源,但,存在的第三上行资源均不满足目标逻辑信道的LCP时,UE可以执行确定未激活BWP上是否存在第二上行资源的技术过程。
可选的,与上文所述同理地,在本公开实施例中,UE可以逐一确定该n个未激活BWP中的每个未激活BWP上是否存在第三上行资源,当某一未激活BWP上存在第三上行资源,且,该第三上行资源满足目标逻辑信道的LCP时,UE可以停止确定其他的未激活BWP上是否存在第三上行资源。
可选的,在本公开实施例中,UE还可以逐一确定该n个未激活BWP中的每个未激活BWP上是否存在第二上行资源和第三上行资源,当某一未激活BWP上存在第二上行资源或者满足目标逻辑信道的LCP的第三上行资源时, UE可以停止确定其他的未激活BWP上是否存在第二上行资源或第三上行资源。
UE逐一确定该n个未激活BWP中的每个未激活BWP上是否存在第二上行资源,或,第三上行资源,或,第二上行资源和第三上行资源的方式可以在一定程度上降低UE需要进行确定的次数,从而可以提高UE向基站请求上行资源的效率。
在另一种可能的实现方式中,UE确定n个未激活BWP中的每个未激活BWP上是否存在第二上行资源之前,还可以确定第二激活BWP上是否存在用于发送随机接入请求的第四上行资源,其中,该第四上行资源位于物理随机接入信道(英文:Physical Random Access Channel;简称:PRACH)上。
当第二激活BWP上存在第四上行资源时,UE可以通过该第四上行资源向基站发送随机接入请求,并退出流程。
当第二激活BWP上不存在第四上行资源时,UE可以执行确定未激活BWP上是否存在第二上行资源的技术过程。
其中,该第二激活BWP位于特殊小区中;或者,该第二激活BWP位于激活的服务小区中。
步骤303、当n个未激活BWP中的每个未激活BWP上均不存在第二上行资源时,UE进行随机接入。
当该n个未激活BWP中的每个未激活BWP上均不存在第二上行资源时,UE无法通过未激活BWP向基站发送SR,在这种情况下,UE可以进行随机接入,也即是,UE可以向基站发送随机接入请求。
若UE在执行确定n个未激活BWP中的每个未激活BWP上是否存在第二上行资源的技术过程之前,已经执行了确定第二激活BWP上是否存在第四上行资源的技术过程,则UE在步骤303中进行随机接入时,可以确定n个未激活BWP上是否存在用于发送随机接入请求的第五上行资源,若该n个未激活BWP上存在第五上行资源,则UE可以通过该第五上行资源向基站发送随机接 入请求。
若UE在执行确定n个未激活BWP中的每个未激活BWP上是否存在第二上行资源的技术过程之前,没有执行确定第二激活BWP上是否存在第四上行资源的技术过程,则UE在步骤303中进行随机接入时,可以确定第二激活BWP上是否存在第四上行资源,在该第二激活BWP上存在第四上行资源时,UE可以通过该第四上行资源向基站发送随机接入请求,在该第二激活BWP上不存在第四上行资源时,UE可以确定n个未激活BWP上是否存在第五上行资源,若该n个未激活BWP上存在第五上行资源,则UE可以通过该第五上行资源向基站发送随机接入请求。
可选的,若UE在执行确定n个未激活BWP中的每个未激活BWP上是否存在第二上行资源的技术过程之前,没有执行确定n个未激活BWP中的每个未激活BWP上是否存在第三上行资源的技术过程,则在进行随机接入之前,UE可以确定n个未激活BWP中的每个未激活BWP上是否存在第三上行资源。
当该n个未激活BWP中的每个未激活BWP上均不存在第三上行资源时,或者,当该n个未激活BWP中的未激活BWP上存在第三上行资源,但,存在的第三上行资源均不满足目标逻辑信道的LCP时,UE可以进行随机接入。
当第二未激活BWP上存在第三上行资源,且,第二未激活BWP上的第三上行资源满足目标逻辑信道的LCP时,UE可以通过第二未激活BWP上的第三上行资源向基站发送目标逻辑信道中的上行通信数据,并退出流程。其中,第二未激活BWP是上述n个未激活BWP中的一个BWP。
步骤304、当第一未激活BWP上存在第二上行资源时,通过第一未激活BWP上的第二上行资源向基站发送SR。
其中,第一未激活BWP为上述n个未激活BWP中的BWP。
在本公开实施例中,很可能会出现n个未激活BWP中的m个未激活BWP上均存在第二上行资源的情况,其中,m为小于n的正整数,此时,UE可以根据预定的选择顺序从该m个未激活BWP中选择出第一未激活BWP,并通 过第一未激活BWP上的第二上行资源向基站发送SR。
其中,预定的选择顺序可以为优先级由高至低的顺序,BWP标识由小到大的顺序,网络侧指定的顺序等,本公开实施例在此不做具体限定。其中,该优先级可以是网络侧配置的优先级。
综上所述,本公开实施例提供的上行调度请求的发送方法,通过在第一激活BWP上不存在用于传输SR的位于PUCCH上的第一上行资源时,确定n个未激活BWP中的每个未激活BWP上是否存在用于传输SR的位于PUCCH上的第二上行资源,并在第一未激活BWP上存在第二上行资源时,通过该第二上行资源向基站发送SR,其中,第一未激活BWP是n个未激活BWP中的BWP,这样,在UE无法通过第一激活BWP向基站发送SR的情况下,UE可以尝试通过未激活BWP向基站发送SR,因此可以在一定程度上减小UE向基站请求上行资源的过程中UE需要进行随机接入的概率,从而可以提高UE向基站请求上行资源的效率。
