Description

调度请求的处理方法和终端设备 技术领域
本申请实施例涉及通信技术领域,尤其涉及一种调度请求的处理方法和终端设备。
背景技术
在未来5G通信系统中,终端设备可以通过将缓冲状态报告(Buffer Status Report,BSR)填充到媒体接入控制(Media Access Control,MAC)协议数据单元(Protocol Data Unit,PDU)中向网络设备上报终端设备的待发送数据量。相应的,网络设备可以基于终端设备发送的BSR,向终端设备发送上行授权(Uplink grant,UL grant),从而为终端设备分配上行资源。
其中,不同服务质量(Quality of Service,QoS)需求的业务的数据是通过不同的逻辑信道(Logical Channel,LCH)传输的。在未来5G通信系统中,不同的逻辑信道可以支持不同的传输参数集合(可以包括子载波间隔(subcarrier spacing)、循环前缀(cyclic prefix,CP)长度,传输时间长度等)。不同QoS需求的业务在传输时需要通过能够支持相应QoS需求的传输参数集合对应的上行授权来传输。例如,当一个逻辑信道有数据待发送且触发了BSR后,且终端设备有可用的上行授权,则终端设备可以将该BSR填充到MAC PDU中向网络设备上报。网络设备根据该BSR调度该逻辑信道的传输参数集合对应的上行授权给终端设备。终端设备可以通过该上行授权传输该逻辑信道的数据。或者理解为,当终端设备收到网络设备分配的一个上行授权后,如果该上行授权指示的传输数据所用的传输参数集合与逻辑信道相匹配时,终端设备才能通过该上行授权传输该逻辑信道的数据。否则,终端设备无法通过该上行授权传输该逻辑信道的数据。
但是,由于在未来5G通信系统中存在多种传输参数集合,当传输参数集合不同时,调度时间也不同。这样,就会出现网络设备无法及时为逻辑信道分配与逻辑信道匹配的上行资源的问题,导致该逻辑信道承载的数据的时延要求无法得到保证。

具体实施方式
图1为本申请实施例所涉及的一种通信系统的框架图。如图1所示,该通信系统包括:网络设备01和终端设备02。网络设备01和终端设备02可以进行上下行通信。其中,
网络设备01,可以为任一具有管理无线网络资源的设备,或者各种无线接入点。例如:可以是全球移动通讯(Global System of Mobile communication,GSM)或码分多址(Code Division Multiple Access,CDMA)中的基站(Base Transceiver Station,BTS),也可以是宽带码分多址(Wideband Code Division Multiple Access,WCDMA)中的基站(NodeB,NB),还可以是长期演进(Long Term Evolution,LTE)中的演进型基站(Evolutional Node B,eNB或eNodeB),或者中继站或接入点,或者未来5G通信系统中的5G基站(g Node B,gNB)、无线收发设备(NeXt Node,NX),在此并不限定。
终端设备02,可以是手机、平板电脑等无线终端,该无线终端包括向用户提供语音和/或数据服务的设备,终端设备还可以是具有无线连接功能的手持设备、车载设备、可穿戴设备、计算设备,以及各种形式的用户设备UE、移动台(Mobile Station,MS)及终端(terminal),本申请实施例并不限定。
在LTE通信系统及其后续演进通信系统、未来5G通信系统及未来其他通信系统中,终端设备可以通过BSR和调度请求(scheduling request,SR)向网络设备请求上行调度。具体的,终端设备可以将BSR或者SR发送给网络设备。从而,网络设备可以基于终端设备发送的BSR或者SR向终端设备发送上行授权(UL grant),完成上行调度。
下面以LTE通信系统为例,对现有的上行调度过程中涉及的BSR的触发、BSR的重传、SR的触发、SR的传输、SR的取消进行简单的介绍。
1、BSR的触发
在LTE通信系统中,BSR的种类可以有多种,例如,常规BSR(regular BSR)、周期BSR(Periodic BSR)或者附加BSR(Padding BSR)。这里仅介绍常规BSR的触发。
触发常规BSR的条件通常包括如下三种。
1)终端设备的上行数据缓冲(buffer)为空且有新数据到达。
当所有逻辑信道组(Logical Channel Group,LCG)的所有逻辑信道都没有可发送的上行数据时,如果此时属于任意一个LCG的任意一个逻辑信道变得可以发送,则终端设备会触发常规BSR。
2)高优先级的数据到达。
如果终端设备有一个比当前有可用传输数据的逻辑信道有更高优先级且属于一个逻辑信道组的逻辑信道有数据需要到达,则终端设备会触发常规BSR。
3)当BSR重传计时器超时后,并且终端设备的任意一个LCG的任意一个逻辑信道里有数据可以发送时,将会触发常规BSR。
2、BSR的重传
在LTE通信系统中,为了防止BSR的丢失或者BSR的发送顺序和接收顺序不一致导致的网络设备错误理解终端设备的缓存状态,引入了BSR的重传机制。具体如下:
在终端设备侧维护一个BSR重传计时器,该计时器的长度可以与由网络设备配置。
当一个BSR被发送时,会启动或者重启BSR重传计时器。
当终端设备收到一个用于新数据传输的上行授权时,终端设备会重启BSR重传计时器。
当BSR重传计时器时,只要终端设备的任何一个属于一个LCG的逻辑信道有数据传输,那么终端设备会触发常规BSR。
3、SR的触发
在LTE通信系统中,当一个常规BSR被触发后,该常规BSR的状态即视为挂起(pending)状态。
在一个传输时间间隔(Time Transmission Inteveral,TTI)里面,当终端设备有pending的BSR时,如果终端设备在这个TTI里面有针对新数据传输的上行资源时,终端设备可以通过该上行资源来传输BSR。此时不触发SR。
否则,终端设备会进一步触发SR。
4、SR的传输
当一个SR被触发后,该SR的状态即视为挂起(pending)状态。在一个TTI里,如果终端设备没有上行共享信道(Uplink Shared Channel,UL-SCH)资源,那么终端设备会判断当前TTI是否有网络设备为其配置的用于传输SR的物理上行控制信道(Physical Uplink Control Channel,PUCCH)资源。如果有,同时该SR对应的SR禁止计时器没有在运行,终端设备的媒体接入控制(Media Access Control,MAC)层执行如下操作:
通知物理层去传输SR。
将用于记录SR传输次数的变量加1。
开启SR禁止计时器。
5、SR的取消
当满足如下条件时,处于pending状态的SR会被取消。
1)当一个传输的MAC PDU中包含一个BSR,而该BSR包含了直到触发BSR的最近一次事件时的缓存状态,则取消SR。
2)当一个传输的MAC PDU中包含了可用于传输的待传数据时,则取消SR。
在LTE通信系统中,仅有一个传输时间间隔TTI。因此,无论网络设备是基于终端设备发送的BSR来调度上行授权,还是基于终端设备发送的SR来调度上行授权,调度周期都是相同的。终端设备都可以及时获得可以传输上行数据的上行资源。
在未来5G通信系统中,数据在时间域上以时间单元为粒度进行传输。该时间单元可以是子帧、传输时间间隔(一个传输时间间隔等于若干个子帧长度的和,或者若干个传输时间间隔的和等于一个子帧长度)、时隙(slot)、多个时隙聚合、迷你时隙(mini-slot)、多个迷你时隙聚合、迷你时隙和时隙聚合、时域符号、多个时域符号等等。可见,未来5G通信系统中存在多种长度的时间单元。时间单元的长度与频率域上的子载波间隔相关。子载波间隔越小,时域符号越长。也就是说,在未来5G通信系统中存在多种传输参数集合。
在未来5G通信系统中,会出现网络设备无法及时为终端设备的逻辑信道分配与逻辑信道匹配的上行资源的问题,例如,终端设备通过对应第一传输参数集合的UL grant来传输BSR向网络设备上报某一个逻辑信道的上行调度信息,而所述第一传输参数集合对应的UL grant无法满足所述逻辑信道承载的数据的QoS需求,从而导致该逻辑信道承载的数据的时延要求和/或请求资源的控制信令的可靠性要求无法得到保证。在上行调度过程中的各个阶段都可能导致该问题。例如,BSR的重传、SR的触发、SR的传输,等等。
本申请实施例提供的调度请求的处理方法,可以适用于未来5G通信系统及未来其他通信系统,主要应用于上行数据调度。用于实现如何通过能够满足逻辑信道QoS需求的方式来向 网络设备请求上行资源。
下面对本申请实施例涉及的数据调度过程中的相关概念进行简单的介绍。
QoS:一个终端设备可能会同时进行多种业务,每种业务具有相应的QoS要求。不同QoS需求的业务在传输时需要通过能够支持相应QoS需求的传输参数集合的上行授权来传输。
协议栈配置方式:协议栈(Protocol Stack)是指网络中各层协议的总和,其形象的反映了一个网络中文件传输的过程。即,由上层协议到底层协议,再由底层协议到上层协议。作为实例而非限定,在本申请实施例中,无线通信所使用的协议栈可以包括以下至少一个协议层或多个协议层的组合:业务数据适配层协议(Service Data Adaptation Protocol,SDAP),分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路控制(Radio Link Control,RLC)层、媒体接入控制(Media Access Control,MAC)层、物理(Physical)层、无线资源管理(Radio Resource Control,RRC)层。其中,每层协议都可以存在多种协议实体以及定义的多种信道资源。
逻辑信道:MAC层在逻辑信道上提供数据传送业务,表示承载的内容是什么。网络设备会为终端设备配置逻辑信道可用的/可映射的传输参数集合。
逻辑信道组LCG:多个逻辑信道组成的集合,通常由网络设备配置。
上行资源:可以理解为上行传输信道UL-SCH或者上行物理信道PUSCH的资源,用于传输终端设备的数据。
物理资源:物理层的资源,包括时域资源和频域资源。
时间单元:在时间域上传输上层数据和/或物理控制信令的时间粒度。
传输参数集合:一个逻辑信道可用的/可映射的传输参数集合中的参数可以包含但不限于仅包含下列中的至少一项:子载波间隔、循环前缀长度、上行资源传输的时间长度、调度上行资源的控制信令与被调度的上行资源传输的时间间隔长度、上行资源所对应的终端设备的服务小区,等等。
SR配置:网络设备会为终端设备配置其每个逻辑信道可用的/可映射的传输参数集合以及每个逻辑信道可用的/可映射的SR配置。一个逻辑信道可以与一个或者多个SR配置相关联。所述SR配置的概念可以有以下情况:
1)所述SR配置中包含SR配置的标识、SR禁止计时器和SR最大传输次数,同时也包含用于确定传输SR所用的物理资源位置的参数。这种情况下,一个逻辑信道会关联/映射到至少一个SR配置。
2)所述SR配置中包含SR配置的标识、SR禁止计时器和SR最大传输次数,但不包含用于确定传输SR所用的物理资源位置的参数。用于确定传输SR所用的物理资源位置的参数包含在另外的SR相关配置中,例如该SR相关配置可以成为SR资源配置。
这种情况下,一个逻辑信道会关联/映射到至少一个SR配置,而一个SR配置又会关联/映射到至少一个SR资源配置。
根据终端设备发送的SR所对应的SR配置(如果是上述情况1)或者对应的SR资源配置(如果是上述情况2),以及SR配置或者SR资源配置与逻辑信道的关联/映射关系,网络设备可以知道终端设备当前需要何种传输参数集合对应的上行授权来传输数据。
此外,在本申请实施例中,在语言描述上,如下技术术语可以相互替换。可用的/映射的,所映射的/所关联的,上行资源/上行授权。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能 在某些实施例中不再赘述。
本申请说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。
实施例一
本实施例应用于上行调度过程中的SR触发场景,涉及如何向网络设备请求上行资源以满足逻辑信道的数据的QoS需求。
图2为现有的无法触发SR的场景示意图。假设,终端设备配置了两个逻辑信道,分别为逻辑信道1(LCH1)和逻辑信道2(LCH2)。其中,
1)网络设备为终端设备配置的LCH1可用的/可映射的传输参数集合的取值为第一取值集合,且网络设备为LCH1配置的所映射的/关联的SR配置为第一SR配置。
2)网络设备为终端设备配置的LCH2可用的/可映射的传输参数集合的取值为第二取值集合,且网络设备为LCH2配置的所映射的/关联的SR配置为第二SR配置。
3)LCH2的优先级高于LCH1的优先级。
如图2所示,上行调度过程如下:
在时刻T0,LCH1的数据到达触发了一个常规BSR,标记为BSR1。由于终端设备没有可用的上行资源,所以BSR1可以触发与LCH1关联的SR,标记为SR1。终端设备将包含LCH1的LCG的缓冲大小(buffer size)上报给网络设备。此后,网络设备开始调度对应传输参数集合的取值为第一取值集合的上行资源/上行授权给终端设备。
在时刻T1,LCH2的数据到达触发了一个常规BSR,标记为BSR2。在时刻T1,终端设备有网络设备调度的对应传输参数集合的取值为第一取值集合的上行授权。因此,终端设备可以通过该上行授权将包含LCH2的LCG的缓冲大小上报给网络设备。网络设备收到BSR2后,可以根据BSR2开始调度对应传输参数集合的取值为第二取值集合的上行授权给终端设备。LCH2的数据的时延为:从时刻T1开始到终端设备收到网络设备发送的对应传输参数集合的取值为第二取值集合的上行授权为止的这段时间。时延很大。
在从时刻T1开始直到网络设备收到BSR2并向终端设备发送对应传输参数集合的取值为第二取值集合的上行授权的这段时间内,由于终端设备一直有网络设备调度的对应传输参数集合的取值为第一取值集合的上行授权,即调度LCH1的数据传输的上行授权,因此,根据现有的触发SR的条件,终端设备无法触发与LCH2关联的SR。
可见,在该场景下,尽管终端设备上报了BSR2,但是,LCH1可用的/可映射的传输参数集合的取值为第一取值集合,LCH2可用的/可映射的传输参数集合的取值为第二取值集合,两者并不相同。通过对应传输参数集合的取值为第一取值集合的上行授权传输BSR2来请求上行资源,会导致LCH2的上行数据传输的时延要求得不到满足。而终端设备又无法触发与LCH2关联的SR,因此无法通过发送与LCH2关联的SR来更快的请求上行资源。另一方面,通过传输参数集合的取值为第一取值集合的上行授权来传输BSR2从而来为LCH2请求上行资源,可能也无法满足LCH2对请求上行资源的控制信令的可靠性要求。
本实施例提供了一种调度请求的处理方法,用以解决当BSR被触发后,终端设备有上行资源来传输BSR,但是该上行资源与触发BSR的逻辑信道的传输参数不匹配,从而导致该逻辑信道承载的数据的时延要求和/或请求资源的控制信令的可靠性要求无法得到保证的技术问题。
图3为本申请实施例一提供的调度请求的处理方法的流程图。本实施例提供的调度请求的 处理方法,执行主体可以为终端设备。如图3所示,本实施例提供的调度请求的处理方法,可以包括:
S101、终端设备确定是否有与第一逻辑信道相关联的常规BSR被触发且还未被取消。
具体的,一个常规BSR被触发后直至被取消前,该常规BSR的状态可以视为挂起(pending)状态。第一逻辑信道是指与被触发的常规BSR相关联的逻辑信道。常规BSR被触发的场景很多。第一逻辑信道可能是直接触发该常规BSR的那个逻辑信道,也可能不是直接触发该常规BSR的逻辑信道。在不同的触发常规BSR的场景下,第一逻辑信道可能有所不同。
当确定有与第一逻辑信道相关联的常规BSR被触发且还未被取消时,执行S102。
S102、若与第一逻辑信道相关联的常规BSR被触发且还未被取消,且终端设备没有可用于传输第一逻辑信道的数据的上行资源,则终端设备触发SR。
具体的,当同时满足2个条件时,可以触发与第一逻辑信道相关联的SR。这2个条件为:1)有与第一逻辑信道相关联的挂起状态的BSR;2)没有可用于传输第一逻辑信道的数据的上行资源。其中,第一逻辑信道的数据是指终端设备通过第一逻辑信道待传输的数据,或者称为可用传输数据(available data for transmission)。终端设备没有可用于传输第一逻辑信道的数据的上行资源,这里的“上行资源”是针对“第一逻辑信道”而言的。有上行资源或者没有上行资源,要确定是否可用于传输第一逻辑信道的数据。在另一个方面,这里的“上行资源”,可以理解为UL-SCH的资源和/或PUSCH的资源。
可选的,S102中终端设备触发SR还可以包括一个条件,终端设备的第一计时器没有运行,第一计时器用于延迟SR的传输。此时,若与第一逻辑信道相关联的常规BSR被触发且还未被取消,且终端设备没有可用于传输第一逻辑信道的数据的上行资源,且终端设备的第一计时器没有运行,则终端设备可以触发SR。
在该种实现方式中,当同时满足3个条件时,可以触发与第一逻辑信道相关联的SR。这3个条件为:1)有与第一逻辑信道相关联的挂起状态的BSR;2)没有可用于传输第一逻辑信道的数据的上行资源;3)第一计时器没有运行。即,当第一计时器运行时,将无法触发SR。
对于图2所示场景,在时刻T1,LCH2的数据到达触发了一个常规BSR,标记为BSR2。满足了第1个条件。LCH2为第一逻辑信道。在时刻T1,终端设备有网络设备调度的对应传输参数集合的取值为第一取值集合的上行授权。但是,LCH2可用的/可映射的传输参数集合的取值为第二取值集合。虽然有上行授权,但是该上行授权对于LCH2来说是不可用的。满足了第2个条件。假设第一计时器没有运行,满足了第3个条件。所以,终端设备可以触发与LCH2相关联的SR,标记为SR2。具体的上行调度过程可以参见图4,图4为本申请实施例一提供的触发SR的场景示意图。网络设备收到SR2后,可以根据SR2快速开始调度对应传输参数集合的取值为第二取值集合的上行授权给终端设备。LCH2的数据的时延为:从时刻T1开始到终端设备收到网络设备发送的对应传输参数集合的取值为第二取值集合的上行授权为止的这段时间。相比于图2大大缩短了时延,满足了LCH2的上行数据传输的时延要求,同时满足了LCH2对请求上行资源的控制信令的可靠性要求。
可见,当终端设备有BSR被触发且还未取消、终端设备没有可用于传输与BSR相关联的第一逻辑信道的数据的上行资源,且终端设备的第一计时器没有运行时,终端设备可以触发SR。从而通过SR实现更快的请求上行资源来传输第一逻辑信道的数据,满足了第一逻辑信道承载的数据的QoS要求,提升了上行调度性能。
可选的,终端设备没有可用于传输第一逻辑信道的数据的上行资源,可以包括:
终端设备在第一时间单元内没有可用于传输第一逻辑信道的数据的上行资源,和/或,终 端设备没有可用于传输第一逻辑信道的数据的第一类上行资源。
其中,第一类上行资源为网络设备通过无线资源控制层信令为终端设备配置的上行资源,或者为网络设备通过无线资源控制层信令为终端设备配置并通过物理层信令或媒体接入控制层信令激活的上行资源。
终端设备在第一时间单元内没有可用于传输第一逻辑信道的数据的上行资源,这里的“上行资源”,可以包括第一类上行资源和第二类上行资源。其中,第二类上行资源可以包括网络设备通过终端设备专用的标识,例如小区无线网络临时标识(Cell-Radio Network Temporary Identifier,C-RNTI)加扰的PDCCH调度的上行授权。在另一个方面,这里的“上行资源”,可以理解为UL-SCH资源和/或PUSCH资源。
可选的,终端设备在第一时间单元内没有可用于传输第一逻辑信道的数据的上行资源,可以包括:
终端设备在第一时间单元内没有任何可用的上行资源;或者,
终端设备在第一时间单元内有可用的上行资源,但终端设备在第一时间单元内可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同。
具体的,终端设备在第一时间单元内没有任何可用的上行资源,或者,终端设备在第一时间单元内有可用的上行资源,这里的“上行资源”是针对“终端设备”而言的,可以包括第一类上行资源和第二类上行资源。可以理解,“终端设备可用的上行资源”与“可用于传输第一逻辑信道的数据的上行资源”是不同的。当终端设备在第一时间单元内可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同时,该上行资源对于“终端设备”来说是可用的,但是对于“第一逻辑信道”来说就是不可用的。在另一个方面,这里的“上行资源”,可以包括UL-SCH和PUSCH。
其中,传输参数集合中可以包括多个参数。只要有一个参数的取值不同,即为不同的传输参数集合。
可选的,终端设备没有可用于传输第一逻辑信道的数据的第一类上行资源,可以包括:
终端设备没有任何可用的第一类上行资源;或者,
终端设备有可用的第一类上行资源,但终端设备可用的第一类上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同。
具体的,终端设备没有任何可用的第一类上行资源,或者,终端设备有可用的第一类上行资源,这里仅涉及“第一类上行资源”。可以理解,“终端设备可用的第一类上行资源”与“可用于传输第一逻辑信道的数据的第一类上行资源”是不同的。在另一个方面,这里的“上行资源”,可以包括UL-SCH和PUSCH。
综上,终端设备没有可用于传输第一逻辑信道的数据的上行资源,至少可以包括如下的实现方式。
第一种实现方式:终端设备在第一时间单元内没有任何可用的上行资源。
第二种实现方式:终端设备在第一时间单元内有可用的上行资源,但终端设备在第一时间单元内可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同。
第三种实现方式:终端设备没有任何可用的第一类上行资源。
第四种实现方式:终端设备有可用的第一类上行资源,但终端设备可用的第一类上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不 同。
第五种实现方式:终端设备在第一时间单元内没有任何可用的上行资源,并且,终端设备没有任何可用的第一类上行资源。
第六种实现方式:终端设备在第一时间单元内没有任何可用的上行资源。并且,终端设备有可用的第一类上行资源,但终端设备可用的第一类上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同。
第七种实现方式:终端设备在第一时间单元内有可用的上行资源,但终端设备在第一时间单元内可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同。并且,终端设备没有任何可用的第一类上行资源。
第八种实现方式:终端设备在第一时间单元内有可用的上行资源,但终端设备在第一时间单元内可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同。并且,终端设备有可用的第一类上行资源,但终端设备可用的第一类上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同。
可选的,若终端设备没有可用于传输第一逻辑信道的数据的上行资源,但是与第一逻辑信道相关联的常规BSR能够被包含在通过所述上行资源传输的MAC PDU中时,也不取消所述与第一逻辑信道相关联的常规BSR。此时,终端设备在第一时间单元内有可用的上行资源,但终端设备在第一时间单元内可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同。或者,终端设备有可用的第一类上行资源,但终端设备可用的第一类上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同。
需要说明,第一时间单元可以有多种实现方式,下面通过具体示例详细说明第一时间单元。当然,本实施例中的第一时间单元可以包括但不限定仅有下列的实现方式。而且,本实施例中的其他时间单元,与第一时间单元相似,也可以包括但不限定仅有下列的实现方式。
第一种实现方式:一个默认/预定义的时间长度,例如该时间长度可以为某个参考的子载波间隔所对应的符号长度组成的一个时隙(Slot)的时间长度。所述参考的子载波间隔例如可以为15KHz的子载波间隔。
第二种实现方式:终端设备接收到的上行资源对应的传输时间长度。不同的上行资源可能会使用不同的子载波间隔。因此对应的一个符号的长度可能不相同。而不同上行资源占用的符号个数可能也不同。因此终端设备会接收到传输长度不同的上行资源。
第三种实现方式:调度终端设备的上行资源的下行控制信令对应的传输时间长度。不同的下行控制信令可能会使用不同的子载波间隔。因此对应的一个符号的长度可能不相同。而不同的下行控制信令传输时占用的符号个数可能也不同。因此,终端设备会接收到传输长度不同的下行控制信令。
第四种实现方式:第一逻辑信道可用的/映射的传输参数集合中的子载波间隔所对应的符号长度组成的一个默认/预定义的时间长度。例如,可以为子载波间隔所对应的符号长度组成的一个时隙的时间长度。
第五种实现方式:第一逻辑信道可用的/映射的传输参数集合中的子载波间隔所对应的符号长度和所述逻辑信道的数据传输占用的默认符号数所确定的时间长度。
第六种实现方式:第一逻辑信道可用的/映射的传输参数中的子载波间隔所对应的一个符号的长度。
第七种实现方式:第一逻辑信道所映射的/关联的SR配置中配置的传输SR的物理资源使用的子载波间隔所对应的符号长度组成的一个默认/预定义的时间长度。
第八种实现方式:第一逻辑信道所映射的/关联的SR配置中配置的传输SR的物理资源使用的子载波间隔所对应的符号长度和占用的符号数所确定的时间长度。
第九种实现方式:第一逻辑信道所映射的/关联的SR配置中配置的传输SR的物理资源使用的子载波间隔所对应的一个符号的长度。
可选的,作为一种实现方式,与第一逻辑信道相关联的常规BSR可以为:
由于第一逻辑信道有新数据到达而触发的BSR。
具体的,当终端设备当前配置的一个逻辑信道有数据到达时,如果根据BSR的触发条件可以触发一个常规BSR。该逻辑信道即为第一逻辑信道。可以参见图2或者图4。
可选的,第一逻辑信道属于一个逻辑信道组。
可选的,作为另一种实现方式,与第一逻辑信道相关联的常规BSR可以为:
由于BSR重传计时器超时而触发的BSR,且第一逻辑信道为终端设备当前所有第二逻辑信道中优先级最高的逻辑信道。其中,第二逻辑信道为有可用传输数据的逻辑信道或者为有可用传输数据且属于一个逻辑信道组的逻辑信道。
可选的,作为另一种实现方式,与第一逻辑信道相关联的常规BSR可以为:
由于BSR重传计时器超时而触发的BSR,且第一逻辑信道为终端设备当前所有第二逻辑信道中关联的传输参数集合中的如下两个参数的任意一个取值最短的逻辑信道。
参数1:传输上行资源传输的时间长度。
参数2:调度上行资源的控制信令与被调度的上行资源传输的时间间隔长度。
其中,第二逻辑信道为有可用传输数据的逻辑信道或者为有可用传输数据且属于一个逻辑信道组的逻辑信道。
需要说明,BSR重传计时器的作用和原理可以与现有通信系统中的BSR重传计时器相同。
本实施例提供了一种调度请求的处理方法,包括:终端设备确定是否有与第一逻辑信道相关联的常规BSR被触发且还未被取消,若与第一逻辑信道相关联的常规BSR被触发且还未被取消,且终端设备没有可用于传输第一逻辑信道的数据的上行资源,且终端设备的第一计时器没有运行,则终端设备触发SR。本实施例提供的调度请求的处理方法,在BSR被触发之后还未取消之前,如果终端设备没有可用于传输与BSR相关联的逻辑信道的数据的上行资源,且终端设备的第一计时器没有运行时,终端设备可以通过触发SR实现更快的请求上行资源来传输逻辑信道的数据,满足了逻辑信道承载的数据的QoS要求,提升了上行调度性能。
实施例二
本实施例应用于上行调度过程中的SR传输场景,在上述图3所示实施例一的基础上,涉及在已经触发了SR之后如何进行SR的传输。
图5为本申请实施例二提供的调度请求的处理方法的流程图。如图5所示,本实施例提供的调度请求的处理方法,在S102之后,还可以包括:
S201、终端设备确定第一逻辑信道或触发的SR对应的SR配置。
其中,SR配置可以包括以下参数中的至少一项:SR配置的标识、SR禁止计时器、SR最大传输次数和用于确定传输SR所用的物理资源位置的参数。
所述SR配置的概念可以有以下情况:
1)所述SR配置中包含SR配置的标识、SR禁止计时器和SR最大传输次数,同时也包含用 于确定传输SR所用的物理资源位置的参数。这种情况下,一个逻辑信道会关联/映射到至少一个SR配置。
2)所述SR配置中包含SR配置的标识、SR禁止计时器和SR最大传输次数,但不包含用于确定传输SR所用的物理资源位置的参数。用于确定传输SR所用的物理资源位置的参数包含在另外的SR相关配置中,例如该SR相关配置可以成为SR资源配置。这种情况下,一个逻辑信道会关联/映射到至少一个SR配置,而一个SR配置又会关联/映射到至少一个SR资源配置。
以下描述中的SR配置可以理解为上述情况1)对应的SR配置,也可以理解为上述情况2)对应的SR资源配置。
具体的,在触发与第一逻辑信道相关联的SR之后,该SR的状态可以视为挂起(pending)状态。终端设备确定传输该SR使用的SR配置为与第一逻辑信道相关联的SR配置。举例说明,参见图4,终端设备触发了与LCH2相关联的SR2,终端设备可以确定LCH2或SR2对应的SR配置为第二SR配置。
其中,SR配置的标识用于唯一区分不同的SR配置。SR禁止计时器在运行时,无法进行SR的传输。SR最大传输次数指示了可以发送SR的次数的最大值。用于确定传输SR所用的物理资源位置的参数,包括可以确定传输SR所用的物理资源位置的相关参数。其中,物理资源是指时域资源和频率资源。在另一个方面,物理资源可以包括PUCCH。
可选的,本实施例提供的调度请求的处理方法,在一种实现方式中,还可以包括:
对于每个第一时间单元,若终端设备在第一时间单元内没有可用于传输第一逻辑信道的数据的上行资源、终端设备在第一时间单元和第二时间单元时间上重叠的时间内有SR配置对应的用于传输SR的物理资源,并且SR禁止计时器没有运行,终端设备在物理资源上发送SR。
具体的,当同时满足3个条件时,终端设备可以传输与第一逻辑信道相关联的SR。这3个条件为:1)对于每个第一时间单元,终端设备在第一时间单元内没有可用于传输第一逻辑信道的数据的上行资源;2)对于每个第一时间单元,终端设备在第一时间单元和第二时间单元时间上重叠的时间内有SR配置对应的用于传输SR的物理资源;3)SR禁止计时器没有运行。举例说明,参见图4,在时刻T1,终端设备有对应传输参数集合的取值为第一取值集合的上行授权,但是该上行授权对于LCH2不可用,满足了第1个条件。终端设备在第一时间单元和第二时间单元时间上重叠的时间内有第二SR配置对应的用于传输SR2的物理资源,即图4中
Figure PCTCN2018086898-appb-000001
指示的物理资源,满足了第2个条件。假设SR禁止计时器没有运行,满足了第3个条件。所以,终端设备可以在物理资源上发送SR2。
其中,“第一时间单元”是针对“挂起状态的常规BSR”而言的,用于指示常规BSR被触发后直至被取消过程中的全部或者部分时间。“第二时间单元”是针对“SR”而言的。第一时间单元和第二时间单元在时间上有重叠的时间,可以包括:1)第一时间单元和第二时间单元为相同的时间单元;2)第一时间单元和第二时间单元为两个时间单元,并且,第一时间单元指示的时间长度与第二时间单元指示的时间长度相同。也可以理解为,第一时间单元和第二时间单元在时间上完全重叠;3)第一时间单元和第二时间单元为两个时间单元,并且,第一时间单元指示的时间长度大于第二时间单元指示的时间长度,或者,第二时间单元指示的时间长度大于第一时间单元指示的时间长度。也可以理解为,第一时间单元和第二时间单元在时间上为一个时间单元指示的时间长度完全覆盖另一个时间单元指示的时间长度;4)第一时间单元和第二时间单元为两个时间单元,并且,第一时间单元指示的时间长度与第二时间单元指示的时间长度部分重叠,或者,第二时间单元指示的时间长度与第一时间单元指示的时间长度部分重叠。也可以理解为,第一时间单元和第二时间单元在时间上为一个时间单 元指示的时间长度部分覆盖另一个时间单元指示的时间长度。
可选的,在本实现方式中,终端设备在确定是否可以传输与第一逻辑信道相关联的SR时,除了上述3个条件外,进一步还包含第4条件:即所述第一时间单元和或第二时间单元不属于测量间隔(Measurement Gap)的一部分。
需要说明,第二时间单元可以有多种实现方式,其实现方式的技术原理与图3所示实施例一中第一时间单元相似,此处不再赘述。
可选的,本实施例提供的调度请求的处理方法,在另一种实现方式中,还可以包括:
对于每个第一时间单元,若终端设备在第一时间单元内没有可用于传输第一逻辑信道的数据的上行资源、终端设备在第一时间单元内有SR配置对应的用于传输SR的物理资源,并且SR禁止计时器没有运行,终端设备在物理资源上发送SR。
具体的,当同时满足3个条件时,终端设备可以传输与第一逻辑信道相关联的SR。这3个条件为:1)对于每个第一时间单元,终端设备在第一时间单元内没有可用于传输第一逻辑信道的数据的上行资源;2)终端设备在第一时间单元内有SR配置对应的用于传输SR的物理资源;3)SR禁止计时器没有运行。在该种实现方式中,仅有第一时间单元这一个时间单元。
可选的,在本实现方式中,终端设备在确定是否可以传输与第一逻辑信道相关联的SR时,除了上述3个条件外,进一步还包含第4条件:即所述第一时间单元和或第二时间单元不属于测量间隔(Measurement Gap)的一部分。
可选的,本实施例提供的调度请求的处理方法,在另一种实现方式中,还可以包括:
对于每个第二时间单元,若终端设备在第一时间单元和第二时间单元时间上重叠的时间内没有可用于传输第一逻辑信道的数据的上行资源、终端设备在第二时间单元时间内有SR配置对应的用于传输SR的物理资源,并且SR禁止计时器没有运行,则终端设备在物理资源上发送SR。
所述第一时间单元和所述第二时间单元的含义同上所述。
可选的,在本实现方式中,终端设备在确定是否可以传输与第一逻辑信道相关联的SR时,除了上述3个条件外,还可以进一步包含第4条件:即所述第一时间单元和或第二时间单元不属于测量间隔(Measurement Gap)的一部分。
可选的,终端设备在第一时间单元内没有可用于传输第一逻辑信道的数据的上行资源,可以包括:
终端设备在第一时间单元内没有任何可用的上行资源。或者,
终端设备在第一时间单元内有可用的上行资源,但终端设备在第一时间单元内可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同。
其技术原理与图3所示实施例相似,此处不再赘述。
可选的,若终端设备在第一时间单元内有可用的上行资源,但终端设备在第一时间单元内可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同,在一种实现方式中,还可以包括:
若终端设备被配置支持在第一物理信道和第二物理信道上的并行传输,终端设备在第一时间单元内可用的上行资源上传输数据。
具体的,第一物理信道和第二物理信道为不同的两个物理信道,分别用于传输数据和上行控制信息。例如,第一物理信道可以为PUSCH,第二物理信道可以为PUCCH。终端设备被配置支持在第一物理信道和第二物理信道上的并行传输,即,终端设备可以在第一物理信道 上传输上层数据,同时,也可以在第二物理信道上传输上行控制信息。此时,终端设备在物理资源上发送与第一逻辑信道相关联的SR,同时,终端设备在上行资源上发送数据。举例说明,参见图4,终端设备可以在LCH2的SR资源上传输SR2,同时,可以在LCH1的上行资源上传输BSR2和LCH1的数据。
这里的“数据”包括物理层以上的各种用户面数据和控制面数据以及MAC,RLC,PDCP,SDAP层产生的控制信令。
通过终端设备被配置支持在第一物理信道和第二物理信道上的并行传输,可以提升数据传输效率和资源利用率。
可选的,若终端设备在第一时间单元内有可用的上行资源,但终端设备在第一时间单元内可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同,在另一种实现方式中,还可以包括:终端设备不在第一时间单元内可用的上行资源上传输数据,而仅在物理资源上发送SR。
具体的,由于终端设备不支持同时在第一物理信道和第二物理信道上的并行传输,因此仅在物理资源上发送SR,以确保上行资源的及时调度来满足第一逻辑信道的数据的QoS需求。
可选的,终端设备不在第一时间单元内可用的上行资源上传输数据,而仅在物理资源上发送SR,在一种实现方式中,可以包括:
终端设备的MAC层通知PHY层在可用的物理资源上向网络设备发送SR,而MAC层不通知PHY层在可用的PUSCH资源上向网络设备发送数据。
可选的,终端设备不在第一时间单元内可用的上行资源上传输数据,而仅在物理资源上发送SR,在另一种实现方式中,可以包括:
终端设备的MAC层通知PHY层在可用的物理资源上向网络设备发送SR,并在可用的PUSCH资源上向网络设备发送数据。这里的数据可以理解为传输块(Transport Block)。
终端设备的PHY层在可用的物理资源上向网络设备发送SR,而不在可用的PUSCH资源上向网络设备发送数据。PHY层直接丢弃从MAC层收到的数据。

终端设备的PHY层在可用的PUSCH资源上向网络设备发送数据。
在PHY传输所述数据的过程中,PHY层收到了MAC层递交的传输所述SR的通知或指示。此时,终端设备的PHY层在可用的物理资源上向网络设备发送SR而对所述正通过PUSCH传输的数据,PHY层可以采取如下两种处理措施。

S301、若终端设备有可用于传输第一逻辑信道的数据的上行资源,则终端设备取消SR。
具体的,在终端设备触发与第一逻辑信道相关联的SR之后,只要终端设备有可用于传输第一逻辑信道的数据的上行资源,均可以取消SR。从而节省资源,节省终端耗电,同时避免网络设备造成重复调度和调度错误,造成资源浪费。
可选的,在一种实现方式中,终端设备有可用于传输第一逻辑信道的数据的上行资源,可以包括:
终端设备有可用的上行资源且终端设备可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值相同,并且,终端设备可用的上行资源传输的数据单元中包含缓存状态报告并且缓存状态报告中至少包含第一逻辑信道所属的逻辑信道组的缓存大小。
可选的,在另一种实现方式中,终端设备有可用于传输第一逻辑信道的数据的上行资源,包括:

可选的,在又一种实现方式中,终端设备有可用于传输第一逻辑信道的数据的上行资源,包括:

其中,传输参数集合中可以包括多个参数。只有所有参数的取值均相同,才为相同的传输参数集合。
本实施例提供了一种调度请求的处理方法,在已经触发了与第一逻辑信道相关联的SR之后,只要终端设备有可用于传输第一逻辑信道的数据的上行资源,则取消SR。节省了资源,避免了资源浪费,同时节省了终端耗电。
实施例四
本实施例应用于上行调度过程中的SR传输场景,涉及在已经触发了SR之后如何进行SR的传输以满足逻辑信道的数据的QoS需求。
图7为现有的无法传输SR的场景示意图。其中,逻辑信道的配置可以参见图2。
如图7所示,上行调度过程如下:
在时刻T0,LCH1的数据到达触发了一个常规BSR,标记为BSR1。由于终端设备没有可用的上行资源,所以BSR1可以触发与LCH1关联的SR,标记为SR1。终端设备将包含LCH1的LCG的缓冲大小(buffer size)上报给网络设备。此后,网络设备开始调度对应传输参数集合的取值为第一取值集合的上行资源/上行授权给终端设备。
在时刻T1,LCH2的数据到达触发了一个常规BSR,标记为BSR2。在时刻T1,网络设备没有为终端设备调度任何的上行授权。因此,终端设备会触发与LCH2关联的SR,标记为SR2。 LCH2所映射/关联的SR配置对应的可用于发送SR2的物理资源的下一个最早出现的时刻为时刻T3。但是在从时刻T2直到网络设备收到包含BSR2并发送对应传输参数集合的取值为第二取值集合的上行授权这段时间内,由于终端设备一直有网络设备调度的对应传输参数集合的取值为第一取值集合的上行授权,即调度LCH1的数据传输的上行授权。因此终端设备无法发送由于LCH2有数据到达而触发的SR2。当上述情况发生时,尽管终端设备上报了BSR2,但是通过对应传输参数集合的取值为第一取值集合的上行授权传输BSR2来请求上行资源,无法满足LCH2的时延要求,而终端设备又不能发送与LCH2相关联的SR2来更快的请求上行资源。因此会导致LCH2的上行数据传输的时延要求得不到满足。另一方面,通过传输参数集合的取值为第一取值集合的上行授权来传输BSR2从而来为LCH2请求上行资源,可能也无法满足LCH2对请求上行资源的控制信令的可靠性要求。
本实施例提供了一种调度请求的处理方法,用以解决当SR被触发后由于SR无法传输而导致的逻辑信道承载的数据的时延要求和/或请求资源的控制信令的可靠性要求无法得到保证的技术问题。
图8为本申请实施例四提供的调度请求的处理方法的流程图。本实施例提供的调度请求的处理方法,执行主体可以为终端设备。如图8所示,本实施例提供的调度请求的处理方法,可以包括:
S401、若终端设备有与第一逻辑信道相关联的SR被触发且还未被取消,终端设备确定第一逻辑信道或者所述SR对应的SR配置。
其中,SR配置包括以下参数中的至少一项:SR配置的标识、SR禁止计时器、SR最大传输次数和用于确定传输SR所用的物理资源位置的参数。
所述SR配置的概念可以有以下情况:
1)所述SR配置中包含SR配置的标识、SR禁止计时器和SR最大传输次数,同时也包含用于确定传输SR所用的物理资源位置的参数。这种情况下,一个逻辑信道会关联/映射到至少一个SR配置。
2)所述SR配置中包含SR配置的标识、SR禁止计时器和SR最大传输次数,但不包含用于确定传输SR所用的物理资源位置的参数。用于确定传输SR所用的物理资源位置的参数包含在另外的SR相关配置中,例如该SR相关配置可以成为SR资源配置。这种情况下,一个逻辑信道会关联/映射到至少一个SR配置,而一个SR配置又会关联/映射到至少一个SR资源配置。
以下描述中的SR配置可以理解为上述情况1)对应的SR配置,也可以理解为上述情况2)对应的SR资源配置。
具体的,与第一逻辑信道相关联的SR被触发之后,该SR的状态可以视为挂起(pending)状态。第一逻辑信道是指与被触发的SR相关联的逻辑信道。如果终端设备有与第一逻辑信道相关联的SR被触发且还未被取消,终端设备确定第一逻辑信道或者SR对应的SR配置。举例说明,在图7所示场景中,终端设备触发了与LCH2相关联的SR2,终端设备可以确定LCH2或SR2对应的SR配置为第二SR配置。
其中,SR配置的标识用于唯一区分不同的SR配置。SR禁止计时器在运行时,无法进行SR的传输。SR最大传输次数指示了可以发送SR的次数的最大值。用于确定传输SR所用的物理资源位置的参数,包括可以确定传输SR所用的物理资源位置的相关参数。其中,物理资源是指时域资源和频率资源。在另一个方面,物理资源为PUCCH信道上的物理资源。
需要说明,SR被触发的场景很多。本申请实施例并不限定SR是如何触发的。例如,可以参见图3所示实施例中SR的触发条件。也可以为现有通信系统中的任意可以被触发的SR。
S402、对于每个第一时间单元,若终端设备在第一时间单元内没有可用于传输第一逻辑信道的数据的上行资源、终端设备在第一时间单元和第二时间单元时间上重叠的时间内有SR配置对应的用于传输SR的物理资源,并且SR禁止计时器没有运行,终端设备在物理资源发送SR。
具体的,当同时满足3个条件时,终端设备可以传输与第一逻辑信道相关联的SR。这3个条件为:1)对于每个第一时间单元,终端设备在第一时间单元内没有可用于传输第一逻辑信道的数据的上行资源;2)对于每个第一时间单元,终端设备在第一时间单元和第二时间单元时间上重叠的时间内有SR配置对应的用于传输SR的物理资源;3)SR禁止计时器没有运行。具体的传输SR的过程可以参见图9,图9为本申请实施例四提供的传输SR的场景示意图。终端设备确定SR2对应的SR配置为第二SR配置。终端设备可以在第二SR配置对应的用于传输SR2的物理资源上发送SR2。相比于图7大大缩短了时延,满足了LCH2的上行数据传输的时延要求,同时满足了LCH2对请求上行资源的控制信令的可靠性要求。
其中,第一时间单元和第二时间单元在时间上有重叠的时间,可以包括:1)第一时间单元和第二时间单元为相同的时间单元;2)第一时间单元和第二时间单元为两个时间单元,并且,第一时间单元指示的时间长度与第二时间单元指示的时间长度相同。也可以理解为,第一时间单元和第二时间单元在时间上完全重叠;3)第一时间单元和第二时间单元为两个时间单元,并且,第一时间单元指示的时间长度大于第二时间单元指示的时间长度,或者,第二时间单元指示的时间长度大于第一时间单元指示的时间长度。也可以理解为,第一时间单元和第二时间单元在时间上为一个时间单元指示的时间长度完全覆盖另一个时间单元指示的时间长度;4)第一时间单元和第二时间单元为两个时间单元,并且,第一时间单元指示的时间长度与第二时间单元指示的时间长度部分重叠,或者,第二时间单元指示的时间长度与第一时间单元指示的时间长度部分重叠。也可以理解为,第一时间单元和第二时间单元在时间上为一个时间单元指示的时间长度部分覆盖另一个时间单元指示的时间长度。
可选的,若第一时间单元和第二时间单元为相同的时间单元,则S402可以描述为:
对于每个第一时间单元,若终端设备在第一时间单元内没有可用于传输第一逻辑信道的数据的上行资源、终端设备在第一时间单元内有SR配置对应的用于传输SR的物理资源,并且SR禁止计时器没有运行,终端设备在物理资源上发送SR。
可选的,在本实现方式中,终端设备在确定是否可以传输与第一逻辑信道相关联的SR时,除了上述3个条件外,还可以进一步包含第4条件:即所述第一时间单元和/或第二时间单元不属于测量间隔(Measurement Gap)的一部分。
可选的,本实施例提供的调度请求的处理方法,在另一种实现方式中,还可以包括:
对于每个第二时间单元,若终端设备在第一时间单元和第二时间单元时间上重叠的时间内没有可用于传输第一逻辑信道的数据的上行资源、终端设备在第二时间单元时间内有SR配置对应的用于传输SR的物理资源,并且SR禁止计时器没有运行,终端设备在物理资源上发送SR。
可选的,在本实现方式中,终端设备在确定是否可以传输与第一逻辑信道相关联的SR时,除了上述3个条件外,还可以进一步包含第4条件:即所述第一时间单元和或第二时间单元不属于测量间隔(Measurement Gap)的一部分。
可见,本实施例提供的调度请求的处理方法,当终端设备有与第一逻辑信道相关联的SR被触发且还未被取消,终端设备可以确定第一逻辑信道或者SR对应的SR配置,并在满足条件时在物理资源上发送SR。从而通过SR实现更快的请求上行资源来传输第一逻辑信道的数据, 满足了第一逻辑信道承载的数据的QoS要求,提升了上行调度性能。
需要说明,第一时间单元和第二时间单元可以有多种实现方式,下面通过具体示例详细说明。当然,本实施例中的时间单元可以包括但不限定仅有下列的实现方式。
第一种实现方式:一个默认/预定义的时间长度,例如该时间长度可以为某个参考的子载波间隔所对应的符号长度组成的一个时隙(Slot)的时间长度。所述参考的子载波间隔例如可以为15KHz的子载波间隔。
第二种实现方式:终端设备接收到的上行资源对应的传输时间长度。不同的上行资源可能会使用不同的子载波间隔。因此对应的一个符号的长度可能不相同。而不同上行资源占用的符号个数可能也不同。因此终端设备会接收到传输长度不同的上行资源。
第三种实现方式:调度终端设备的上行资源的下行控制信令对应的传输时间长度。不同的下行控制信令可能会使用不同的子载波间隔。因此对应的一个符号的长度可能不相同。而不同的下行控制信令传输时占用的符号个数可能也不同。因此,终端设备会接收到传输长度不同的下行控制信令。
第四种实现方式:第一逻辑信道可用的/映射的传输参数集合中的子载波间隔所对应的符号长度组成的一个默认/预定义的时间长度。例如,可以为子载波间隔所对应的符号长度组成的一个时隙的时间长度。
第五种实现方式:第一逻辑信道可用的/映射的传输参数集合中的子载波间隔所对应的符号长度和所述逻辑信道的数据传输默认的占用符号数所确定的时间长度。
第六种实现方式:第一逻辑信道可用的/映射的传输参数中的子载波间隔所对应的一个符号的长度。
第七种实现方式:第一逻辑信道所映射的/关联的SR配置中配置的传输SR的物理资源使用的子载波间隔所对应的符号长度组成的一个默认/预定义的时间长度。
第八种实现方式:第一逻辑信道所映射的/关联的SR配置中配置的传输SR的物理资源使用的子载波间隔所对应的符号长度和占用的符号数所确定的时间长度。
第九种实现方式:第一逻辑信道所映射的/关联的SR配置中配置的传输SR的物理资源使用的子载波间隔所对应的一个符号的长度。
可选的,终端设备在第一时间单元内没有可用于传输第一逻辑信道的数据的上行资源,可以包括:
终端设备在第一时间单元内没有任何可用的上行资源。或者,
终端设备在第一时间单元内有可用的上行资源,但终端设备在第一时间单元内可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同。
具体的,终端设备在第一时间单元内没有任何可用的上行资源,或者,终端设备在第一时间单元内有可用的上行资源,这里的“上行资源”是针对“终端设备”而言的,可以包括第一类上行资源和第二类上行资源。可以理解,“终端设备可用的上行资源”与“可用于传输第一逻辑信道的数据的上行资源”是不同的。当终端设备在第一时间单元内可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同时,该上行资源对于“终端设备”来说是可用的,但是对于“第一逻辑信道”来说就是不可用的。在另一个方面,这里的“上行资源”,可以包括UL-SCH和PUSCH。
其中,第一类上行资源为网络设备通过无线资源控制层信令为终端设备配置的上行资源,或者为网络设备通过无线资源控制层信令为终端设备配置并通过物理层信令或媒体接入控制 层信令激活的上行资源。第二类上行资源可以包括网络设备调度的上行授权。
其中,传输参数集合中可以包括多个参数。只要有一个参数的取值不同,即为不同的传输参数集合。
可选的,若终端设备在第一时间单元内有可用的上行资源,但终端设备在第一时间单元内可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同,在一种实现方式中,还可以包括:
若终端设备被配置支持在第一物理信道和第二物理信道上的并行传输,终端设备在第一时间单元内可用的上行资源上传输数据。
具体的,第一物理信道和第二物理信道为不同的两个物理信道,分别用于传输数据和上行控制信息。例如,第一物理信道可以为PUSCH,第二物理信道可以为PUCCH。终端设备被配置支持在第一物理信道和第二物理信道上的并行传输,即,终端设备可以在第一物理信道上传输上层数据,同时,也可以在第二物理信道上传输上行控制信息。此时,终端设备在物理资源上发送与第一逻辑信道相关联的SR,同时,终端设备在上行资源上发送数据。举例说明,参见图4,终端设备可以在LCH2的SR资源上传输SR2,同时,可以在LCH1的上行资源上传输BSR2和LCH1的数据。
这里的“数据”包括物理层以上的各种用户面数据和控制面数据以及MAC,RLC,PDCP,SDAP层产生的控制信令。
通过终端设备被配置支持在第一物理信道和第二物理信道上的并行传输,可以提升数据传输效率和资源利用率。
可选的,若终端设备在第一时间单元内有可用的上行资源,但终端设备在第一时间单元内可用的上行资源的传输参数集合中的参数的取值与第一逻辑信道可用的传输参数集合中的参数的取值不同,在另一种实现方式中,还可以包括:终端设备不在第一时间单元内可用的上行资源上传输数据,而仅在物理资源上发送SR。
具体的,由于终端设备不支持同时在第一物理信道和第二物理信道上的并行传输,因此仅在物理资源上发送SR,以确保上行资源的及时调度来满足第一逻辑信道的数据的QoS需求。
可选的,终端设备不在第一时间单元内可用的上行资源上传输数据,而仅在物理资源上发送SR,在一种实现方式中,可以包括:
终端设备的MAC层通知PHY层在可用的物理资源上向网络设备发送SR,而MAC层不通知PHY层在可用的PUSCH资源上向网络设备发送数据。
可选的,终端设备不在第一时间单元内可用的上行资源上传输数据,而仅在物理资源上发送SR,在另一种实现方式中,可以包括:
终端设备的MAC层通知PHY层在可用的物理资源上向网络设备发送SR,并在可用的PUSCH资源上向网络设备发送数据。这里的数据可以理解为传输块(Transport Block)。
终端设备的PHY层在可用的物理资源上向网络设备发送SR,而不在可用的PUSCH资源上向网络设备发送数据。PHY层直接丢弃从MAC层收到的数据。
可选的,终端设备不在第一时间单元内可用的上行资源上传输数据,而仅在物理资源上发送SR,在又一种实现方式中,可以包括:
终端设备的MAC层通知PHY层在可用的PUSCH资源上向网络设备发送数据。
终端设备的PHY层在可用的PUSCH资源上向网络设备发送数据。
在PHY传输所述数据的过程中,PHY层收到了MAC层递交的传输所述SR的通知或指示。此时,终端设备的PHY层在可用的物理资源上向网络设备发送SR而对所述正通过PUSCH传输 的数据,PHY层可以采取如下两种处理措施。
处理措施一:物理层直接放弃所述数据的传输;
处理措施二:物理层对所述传输的数据进行打孔处理。具体为在与传输的SR重叠的时间内对传输的数据进行打孔处理(Puncture)。
可选的,作为一种实现方式,与第一逻辑信道相关联的SR为:
由于第一逻辑信道有新数据到达而触发的常规BSR所触发的SR。
具体的,当终端设备当前配置的一个逻辑信道有数据到达时,如果根据BSR的触发条件可以触发一个常规BSR。该常规BSR可能触发与该逻辑信道相关联的SR。该逻辑信道即为第一逻辑信道。
可选的,第一逻辑信道属于一个逻辑信道组。
可选的,作为另一种实现方式,与第一逻辑信道相关联的SR为:
由于BSR重传计时器超时而触发的常规BSR所触发的SR,且第一逻辑信道为终端设备当前所有第二逻辑信道中优先级最高的逻辑信道;其中,第二逻辑信道为有可用传输数据的逻辑信道或者为有可用传输数据且属于一个逻辑信道组的逻辑信道。
可选的,作为另一种实现方式,与第一逻辑信道相关联的常规BSR可以为:
由于BSR重传计时器超时而触发的BSR,且第一逻辑信道为终端设备当前所有第二逻辑信道中关联的传输参数集合中的如下两个参数的任意一个取值最短的逻辑信道。
参数1:传输上行资源传输的时间长度。
参数2:调度上行资源的控制信令与被调度的上行资源传输的时间间隔长度。
其中,第二逻辑信道为有可用传输数据的逻辑信道或者为有可用传输数据且属于一个逻辑信道组的逻辑信道。
本实施例提供的调度请求的处理方法,相关技术原理和技术效果还可以参照上述实施例二,在此不再赘述。
本实施例提供了一种调度请求的处理方法,在已经触发了与第一逻辑信道相关联的SR之后,终端设备确定第一逻辑信道或SR对应的SR配置。本实施例提供的调度请求的处理方法,在SR被触发之后可以确保SR的及时传输,从而终端设备可以通过SR实现更快的请求上行资源来传输逻辑信道的数据,满足了逻辑信道承载的数据的QoS要求,提升了上行调度性能。

实施例七
本实施例应用于上行调度过程中的BSR重传场景。
图11为现有的BSR重传的一种场景的示意图,图12为现有的BSR重传的另一种场景的示意图。
如图11和图12所示,终端设备的一个逻辑信道有数据传输从而触发并发送BSR,进而启动BSR重传计时器。当BSR重传计时器在运行时,如果终端设备收到上行资源/上行授权,终端设备会重启BSR重传计时器。而当该上行资源/上行授权对应的传输参数集合的取值并不是触发BSR的LCH的可用的/映射的传输参数集合的取值。由于BSR重传计时器被错误的上行资源/上行授权所重启,从而导致BSR重传计时器的运行时间被延长。因此,如果该BSR发生丢失,那么该BSR被重新触发的时间将被拖延,从而导致触发该BSR的逻辑信道的数据被延迟调度。
本实施例提供了一种调度请求的处理方法,用以解决上述由于BSR被重新触发的时间被拖延而导致的触发该BSR的逻辑信道的数据被延迟调度的技术问题。
本实施例提供的调度请求的处理方法,触发BSR的场景如下。

在某个时刻,终端设备触发一个BSR。所述BSR可以为周期BSR(Periodic BSR),附加BSR(Padding BSR)或者由于BSR重传计时器超时而触发的常规BSR(Regular BSR)。
在该场景中,所述第一逻辑信道为终端设备当前所有第二逻辑信道中优先级最高的逻辑信道。其中,所述第二逻辑信道为有可用传输数据的逻辑信道或者为有可用传输数据且属于一个逻辑信道组的逻辑信道。
触发BSR的场景三。
由于BSR重传计时器超时而触发的BSR,且第一逻辑信道为终端设备当前所有第二逻辑信道中关联的传输参数集合中的如下两个参数的任意一个取值最短的逻辑信道。

参数2:调度上行资源的控制信令与被调度的上行资源传输的时间间隔长度。
在该场景中,所述第一逻辑信道为终端设备当前所有第二逻辑信道中优先级最高的逻辑信道。其中,第二逻辑信道为有可用传输数据的逻辑信道或者为有可用传输数据且属于一个逻辑信道组的逻辑信道。
本实施例提供的调度请求的处理方法,可以包括:
终端设备确定是否有触发并且还未取消的BSR。如果终端设备确定有触发并且还未取消的BSR,那么如果在一个时间单元内,终端设备有针对新数据传输的上行资源,终端设备生成BSR MAC CE,并通过所述上行资源传输所述BSR MAC CE。同时,终端设备启动或者重启BSR重传计时器。启动或者重启BSR重传计时器的值/时间长度根据BSR重传计时器的值/时间长度的配置方案而定。
在一个时间单元内,当终端设备接收到上行资源/上行授权时,如果该上行资源的传输参数集合中的参数的取值与第一逻辑信道的可用的/映射的传输参数集合中的参数的取值相同, 则终端设备重启所述BSR重传计时器。重启的BSR重传计时器的值/时间长度根据BSR重传计时器的值/时间长度的配置方案而定。否则,终端设备不重启所述BSR重传计时器。
其中,一个逻辑信道可用的/映射的传输参数集合中的参数可以包含但不限于仅包含如下的至少一项:子载波间隔、循环前缀长度、上行资源的时间长度、调度所述上行资源的控制信令与所述上行资源的时间间隔长度、所述上行资源所对应的所述终端设备的服务小区。
其中,所述时间单元可以为但不限于仅为以下任何一种情况:
1)一个默认/预定义的时间长度,例如该时间长度可以为某个参考的子载波间隔所对应的符号长度组成的一个时隙(Slot)的时间长度;所述参考的子载波间隔例如可以为15KHz的子载波间隔。
2)终端设备接收到的上行资源对应的传输时间长度。不同的上行资源可能会使用不同的子载波间隔。因此对应的一个符号的长度可能不相同。而不同上行资源占用的符号个数可能也不同。因此,导致终端设备接收到的上行资源对应的传输时间长度。
3)调度终端设备的上行资源的下行控制信令对应的传输时间长度。不同的下行控制信令可能会使用不同的子载波间隔。因此对应的一个符号的长度可能不相同。而不同的下行控制信令传输时占用的符号个数可能也不同。因此,终端设备会接收到传输长度不同的下行控制信令。
4)所述第一逻辑信道可用的/映射的传输参数集合中的子载波间隔所对应的符号长度组成的一个默认/预定义的时间长度。例如,可以为所述子载波间隔所对应的符号长度组成的一个时隙的时间长度。
5)所述第一逻辑信道可用的/映射的传输参数集合中的子载波间隔所对应的符号长度和所述逻辑信道的数据传输默认的占用符号数所确定的时间长度。
6)所述第一逻辑信道可用的/映射的传输参数中的子载波间隔所对应的一个符号的长度。
其中,所述BSR重传计时器的值由网络设备通过专用信令配置给终端设备。其中,BSR重传计时器的值配置可以有如下可选方案:
方案一:网络设备只给终端设备配置一个BSR重传计时器的值。对应该方案,无论由于哪个逻辑信道有数据到达而触发BSR,终端设备启动或者重启的BSR重传计时器的长度都设为所述网络设备配置的值。
方案二:网络设备为终端设备的每个逻辑信道组配置一个BSR重传计时器的值。对应该方案,当属于某个逻辑信道组的某个逻辑信道有数据到达而触发BSR,终端设备启动或者重启的BSR重传计时器的长度的值设为所述网络设备配置的所述逻辑信道组度的BSR重传计时器的值。
方案三:网络设备为终端设备的每个逻辑信道配置一个BSR重传计时器的值。对应该方案,当属于一个逻辑信道组的某个逻辑信道有数据到达而触发BSR,终端设备启动或者重启的BSR重传计时器的长度的值设为所述网络设备配置的所述逻辑信道的BSR重传计时器的值。
方案四:网络设备为终端设备的每个或者每组逻辑信道所映射/所对应的一个或多个SR配置配置一个关联的BSR重传计时器的值。对应该方案,当属于一个逻辑信道组的某个逻辑信道有数据到达而触发BSR,终端设备启动或者重启的BSR重传计时器的长度的值该逻辑信道所映射/所对应的一个或多个SR配置BSR重传计时器的长度的值设为所述网络设备配置的所述逻辑信道所映射/所对应的一个或多个SR配置关联的BSR重传计时器的值。其中,所述一个逻辑信道所映射的/关联的SR配置中可以包括但不限于仅包括以下参数中的至少一项:所述 SR配置的标识、SR禁止计时器、SR最大传输次数、用于确定传输SR所用的物理资源位置的参数。
所述SR配置的概念可以有以下情况:
1)所述SR配置中包含SR配置的标识、SR禁止计时器和SR最大传输次数,同时也包含用于确定传输SR所用的物理资源位置的参数。这种情况下,一个逻辑信道会关联/映射到至少一个SR配置。
2)所述SR配置中包含SR配置的标识、SR禁止计时器和SR最大传输次数,但不包含用于确定传输SR所用的物理资源位置的参数。用于确定传输SR所用的物理资源位置的参数包含在另外的SR相关配置中,例如该SR相关配置可以成为SR资源配置。这种情况下,一个逻辑信道会关联/映射到至少一个SR配置,而一个SR配置又会关联/映射到至少一个SR资源配置。
以下描述中的SR配置可以理解为上述情况1)对应的SR配置,也可以理解为上述情况2)对应的SR资源配置。
需要说明,对于上述方案二、方案三和方案四,终端设备可以只维护/设置一个BSR重传计时器,也可以分别为方案二中的每个逻辑信道组、方案三中的每个逻辑信道和方案四中的每个或者多个SR配置维护/设置一个BSR重传计时器。
本申请实施例提供的调度请求的处理方法,能够避免终端设备由于接收到针对低优先级的逻辑信道的上行资源而导致延迟无法使用所述上行资源来传输数据的高优先级逻辑信道触发的BSR的重传被延迟。从而保证高优先级的逻辑信道触发的BSR能够及时得到重传。另外,通过对不同QoS需求的逻辑信道设置不同的BSR重传计时器时长,也能够保证保证高优先级的逻辑信道触发的BSR能够及时得到重传。
