Description

一种资源分配方法和装置 技术领域
本申请涉及但不限于无线通信技术领域，尤指一种资源分配方法和装置。
背景技术
通用无线分组业务(General Packet Radio Service，简称为：GPRS)的传输时延一直是无线网络运营商关注的一个重要的业务指标。随着移动互联网应用的迅速发展，远程控制、车联网、虚拟现实等物联网以及相关业务对移动网络中的GPRS传输时延提出了更高的要求，即GPRS的超低时延业务成为了第五代移动通信技术(the 5th-Generation mobile communication technology，简称为5G)中的重要性能指标。
对于5G中的超低时延业务，无线接入网通常采用超低时延业务的无线传输策略，其中，采用传输时间间隔(Transmission Time Interval，简称为：TTI)长度小于1毫秒(即短TTI)的无线帧进行超低时延数据传输，上述方式是缩短无线传输时延的重要手段。在目前的长期演进(Long Term Evolution，简称为：LTE)网络中，处于无线资源控制(Radio Resource Control，简称为：RRC)连接态的用户设备(User Equipment，简称为：UE)没有上行数据要传输，演进型基站(Evolved Node B，简称为：eNB)不需要为该UE分配上行资源；当UE从没数据传输到有数据传输时，可以通过发送上行调度请求(Scheduling Request，简称为：SR)消息向eNB请求上行资源；由于无线网中超低时延业务和传统业务是共存的，常规的SR消息仅能表示有数据传输请求，无法表示需要传输的数据对时延的需求，因此，处于RRC连接态的UE如何请求不同时延需求的业务成为目前亟需解决的问题。

附图概述

本发明的实施方式
下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
在目前的LTE网络中，由于eNB不知道UE什么时候需要发送上行数据，即不知道UE什么时候会发送SR消息，所以在UE发送SR消息之前，eNB需要给UE配置SR周期，并在已经分配的SR周期上检测是否有SR消息上报。目前的SR周期的相关参数如表1所示，SR周期最小是1毫秒(ms)时长。
表1
Figure PCTCN2016077020-appb-000001
从上述表1可以看出，相关技术中eNB配置的SR周期的最短时长为1ms，UE在需要发送数据时，需要在配置的SR周期内发送SR消息，并且相关技术中TTI的时长通常为1ms。UE在SR周期内发送的SR消息通常只有1个比特，表示后续是否有数据需要发送，eNB根据该SR消息可以为UE分配上行资源，在UE获取该上行资源后，在分配的上行资源上发送业务请求的具体要求，例如要求发送超低时延业务指示，采用上述技术方案，由于eNB在业务调度时并不知道UE请求的业务是否需要采用超低时延业务进行传输，也就是说，常规的SR消息仅能表示有数据传输请求，无法表示需要传输的数据对时延的需求，因此，处于RRC连接态的UE如何请求不同时延需求的业务成为目前亟需解决的问题。
下面通过具体的实施例对本申请的技术方案进行详细说明，本申请以下各实施例中的基站例如可以为LTE网络中的eNB，并且本申请各实施例中的 eNB可以为UE配置上述表1中任一项SR索引和对应的SR周期，本申请各实施例中的UE和eNB均需要建立RRC连接。本申请提供以下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不再赘述。
图1为本发明实施例提供的一种资源分配方法的流程图。本实施例提供的资源分配方法适用于为UE分配上行资源的情况，该方法可以由资源分配装置执行，该资源分配装置通过硬件和软件结合的方式来实现，该装置可以集成在基站的处理器中，供处理器调用使用。如图1所示，本实施例的方法可以包括以下步骤：
步骤S110，基站接收UE发送的SR消息，该SR消息中包括超低时延业务指示信息。
在本实施例中，UE通常需要在SR周期内发送SR消息，并且本实施例中的SR周期是UE和基站建立RRC连接的过程中，基站为UE配置的，即本实施例在步骤S110之前，本实施例的方法还包括：步骤S100，基站向UE发送RRC连接建立消息，该RRC连接建立消息中配置有用于UE发送SR消息的资源和该资源对应的SR周期，该RRC连接建立消息用于指示UE根据所配置的资源按照该资源对应的SR周期发送SR消息，其中，资源对应的SR周期配置为长度小于1ms的SR短周期。
需要说明的是，本实施中的基站在为UE配置资源时，不局限于上述表1中的相关资源，可以为超低时延业务配置专用的SR短周期，该SR短周期的配置内容如下表2所示。
表2
Figure PCTCN2016077020-appb-000002
如表1和表2所示，配置的资源通常为SR的配置索引ISR值，本实施例在具体实现中，当UE从基站接收到配置的资源，即ISR值后可以进行判断，如果ISR值小于或等于157时，则认为配置了常规的SR周期，按常规SR周 期策略发送SR消息；如果ISR值等于158，则认为配置了超低时延业务专用的SR短周期，由于超低时延业务专用的SR短周期小于一个子帧的长度，所以子帧偏置无需配置，UE可以在任何的超低时延业务专用的SR短周期内发送SR消息。本实施例以基站为UE配置的资源为ISR值等于158为例予以示出，支持超低时延业务的UE在收到RRC连接建立消息后，当超低时延业务触发SR资源请求时，在最近的SR短周期发送时机上发送携带超低时延业务指示信息的SR消息。
步骤S120，基站根据SR消息中的超低时延业务指示信息为UE分配上行超低时延资源。
在本实施例中，SR消息不同于常规的SR消息，本实施例中的SR消息在UE请求超低时延业务时，携带有超低时延业务指示信息，该超低时延业务指示信息例如可以包括超低时延数据待传指示、超低时延级别和超低时延业务的缓存数据量级别中的一项或多项，基站可以根据超低时延业务指示信息的具体形式和内容为UE分配上行超低时延资源；显然地，相比于常规方式中UE等待基站为其分配上行资源后，在分配的上行资源上进行数据反馈时携带超低时延业务指示的方式来说，本实施例提供的方法，基站接收到的SR消息中携带有超低时延业务指示信息，在其分配上行资源时根据该超低时延业务指示信息为UE分配专用于超低时延业务的上行资源，使得UE可以及时地获取到上行超低时延资源，提高了该业务数据传输的时效性。需要说明的是，常规上行资源中TTI时长为1ms，上行超低时延资源中TTI时长通常要小于1ms，例如可以为1符号，或0.5ms等。
本实施例提供的方法在实际应用中，还存在另一种可能的情况，即本实施例中的基站接收到UE发送的SR消息后，确定出该SR消息中不包括所述超低时延业务指示信息，则根据SR消息为UE分配上行非超低时延资源。该情况类似于常规方式，当SR消息中不包括所述超低时延业务指示信息时，未携带任何指示上行时延业务类型的信息，此时，基站直接分配上行非超低时延资源，该上行非超低时延资源通常为TTI时长等于1ms的上行资源。
本实施例所提供的资源分配方法，基站通过接收UE发送的包括超低时延业务指示信息的SR消息，并且根据该SR消息中的超低时延业务指示信息 为UE分配上行超低时延资源；本实施例提供的方法实现了UE无需在等待基站为其分配上行资源后再向基站反馈超低时延业务指示，即在基站分配上行超低时延资源的过程中，减少了基站和UE交互的次数，相应地提高了基站分配上行超低时延资源的效率，解决了处于RRC连接态的UE在请求数据传输时，常规的SR消息无法指示超低时延业务需求信息的问题。
可选地，本实施例在基站与UE建立RRC连接的过程中，基站为UE配置的SR周期可以被配置为时长小于1ms的SR短周期，实现了UE在更短的时间间隔上发送SR消息，若当期时刻不是SR周期中的发送时刻，则等待更短的时间就可发送SR消息，提高了发送SR消息的时效性，即提高了获取上行超低时延资源的效率。
可选地，图1所示实施例中的超低时延业务指示信息例如包括超低时延数据待传指示，该超低时延数据待传指示用于指示UE当前是否有超低时延业务的数据等待传输；相应地，图1中的步骤S120可以替换为：当超低时延数据待传指示为超低时延业务时，基站为UE分配上行超低时延资源。
举例来说，若有新的超低时延业务的数据到达UE的缓存时，UE可以将超低时延数据待传指示设置为TRUE；若UE的缓存内有未传输完的超低时延业务数据，UE也可以将超低时延数据待传指示设置为TRUE；在其他情况下，UE将超低时延数据待传指示设置为False；上述超低时延数据待传指示在SR消息中的数据格式可以为1比特(bit)，可选地，TRUE表示为1，False表示为0，或者也可以用其他数据格式来表示。在具体实现中，当基站在SR消息中检测到超低时延数据待传指示为TRUE时，可以根据空口资源情况判断是否给UE调度短TTI资源，以及调度哪种长度格式的短TTI资源。
可选地，图2为本发明实施例提供的另一种资源分配方法的流程图，在上述图1所示实施例的基础上，本实施例中的超低时延业务指示信息具体包括超低时延指示值，则步骤S120可以包括：步骤S121，基站判断该基站与UE所支持的TTI能力是否相同，若是，则执行步骤S122；若否，则执行步骤S123。在本实施例的具体实现中，基站接收到UE发送的RRC连接请求消息中可以携带有UE的能力信息，同时基站在向UE发送RRC连接建立消息时，也可以携带有基站的能力信息，即已建立RRC连接的基站和UE双方， 明确的知道自身和对方的TTI能力，该TTI能力为基站分配上行超低时延资源时需要考虑的主要因素。
具体的分配方式为：
步骤S122，当基站判断出该基站与UE所支持的TTI能力相同时，根据超低时延指示值分配对应长度TTI的上行超低时延资源；
步骤S123，当基站判断出该基站与UE所支持的TTI能力不同时，根据基站与UE的TTI能力交集和超低时延指示值，优先分配超低时延指示值对应长度TTI的上行超低时延资源。
举例来说，假设基站和UE都支持三种时长的TTI，具体为：1符号、0.5ms和1ms。基站接收到的SR消息中的超低时延指示值可以通过三个值来表示，如下表3所示。
表3
超低时延指示值 基站分配的资源类型
1 TTI＝1符号
2 TTI＝0.5ms
3 TTI＝1ms
通常地，超低时延指示值越小，对时延的要求越高，即TTI的值越小；另外，本实施例中超低时延指示值可以指示TTI的最大时长为目前通常使用的1ms时长的TTI。上述表3仅为本实施例给出的超低时延指示值与基站分配资源类型的一种可能的对应关系，本申请并不限制超低时延指示值的数量和其对应的TTI时长。
如上所述，若步骤S121中判断出基站与UE所支持的TTI能力相同时，分配上行超低时延资源的具体方式为：
当SR消息中的超低时延指示值为1时，给UE分配1符号时长TTI的上行超低时延资源；
当SR消息中的超低时延指示值为2时，给UE分配0.5毫秒时长TTI的上行超低时延资源；
当SR消息中的超低时延指示值为3时，给UE分配1毫秒时长TTI的上行超低时延资源。
在本实施例的另一种可能的实现方式中，若步骤S121中判断出基站与UE所支持的TTI能力不同时，分配上行超低时延资源的具体方式为：
当SR消息中的超低时延指示值为1时，在基站和UE的TTI能力交集中优先分配TTI时长最接近1符号的上行超低时延资源；
当SR消息中的超低时延指示值为2时，在基站和UE的TTI能力交集中分配上行超低时延资源的优先顺序为：0.5毫秒>1符号>1毫秒；
当SR消息中的超低时延指示值为3时，在基站和UE的TTI能力交集中优先分配TTI时长最接近1毫秒的上行超低时延资源。
本实施例中的超低时延指示值可以为超低时延级别或者超低时延业务的缓存数据量级别；其中，超低时延级别用于指示UE的超低时延业务对端到端时延的需求等级或UE的超低时延业务对调度时延的需求等级，超低时延业务的缓存数据量级别指示UE的缓存区内待传输的超低时延业务数据的总量或者UE的缓存区内待传输的最高优先级超低时延业务的数据量。
一方面，对于超低时延级别的定义进行解释，上述端到端时延可以指空口的端到端时延，即数据从到达发射端缓存直到被正确传输至接收端所消耗的时间；也可以指核心网的端到端时延，即数据在UE和核心网分组数据网关(Packet Data Network Gateway，简称为：PGW)之间正确传输的延时；上述调度时延是指数据从到达发送端缓存直到获得调度在发送端发送为止的时延。
在具体实现中，超低时延级别可根据时延要求的高低来划分为不同粒度的级别，例如：假设端到端时延指空口的端到端时延，并且时延要求从0.1ms至0.5ms不等，可将其划分成2个级别：小于0.2ms为级别1，大于0.2且小于0.5ms为级别2；划分的方式不限于上述描述，也可以将时延划分成更细的级别；通常地，对时延要求越严格，说明UE的超低时延业务数据要求更快被传输。
需要说明的是，超低时延级别在SR消息中的数据格式可以是多种的， 例如当划分了4个级别时，可以采用2bit来表示超低时延级别，也可以采用其他格式来表示超低时延级别；另外，本实施例中的基站在SR消息中检测到超低时延级别时，可以根据级别的不同，来决定不同UE之间的调度优先级，同时决定为不同UE调度哪种长度格式的短TTI资源；通常来说，对时延要求越严的UE获得越高的调度优先级，如果基站支持多种短TTI格式，那么对时延要求越严的UE，基站可为其调度越短的TTI格式的资源。
另一方面，对于超低时延业务的缓存数据量级别的定义进行解释，当UE缓存内有超过1种的超低时延业务数据待传输时，超低时延业务的缓存数据量级别可以指示UE的缓存区内待传输的超低时延业务数据的总量，或者指示UE的缓存区内待传输的最高优先级超低时延业务的数据量，该最高优先级超低时延业务指的是对时延要求最严的业务。在具体实现中，超低时延业务缓存数据量可以根据数据量的高低划分成不同粒度的级别，例如：可以按照500bit为粒度来划分级别，也可以按照1000bit或者其他粒度来划分级别。
需要说明的是，超低时延业务的缓存数据量级别在SR消息中的数据格式可以是多种，例如当划分了4个级别时，可以采用2bit来表示数据量级别；也可以采用其他格式来表示数据量级别；另外，当基站在SR消息中检测到超低时延业务的缓存数据量级别时，根据级别的不同，来决定为UE调度多少短TTI格式的资源，例如：假设基站检测到超低时延业务的缓存数据量级别为500bit以内，且基站支持的短TTI格式为0.5ms，那么基站可为UE调度0.5TTI*1物理资源块(Physical Resource Block，简称为：PRB)的资源，缓存数据量为1000bit以内，那么基站可为UE调度0.5TTI*2PRB的资源。
还需要说明的是，上述超低时延级别和超低时延业务的缓存数据量级别可以结合使用，举例来说，当UE在SR消息内同时传输超低时延级别和超低时延业务的缓存数据量级别，且基站和UE均支持多种格式的短TTI(例如1正交频分复用(OFDM)符号的短TTI和0.5ms短TTI两种格式)时，若UE有2种级别的超低时延业务有数据待传输，则UE可报告1bit的超低时延级别，以及2种级别的超低时延业务数据总量的超低时延业务的缓存数据量级 别，相应地，基站可以根据上述信息，按照保证最高优先级超低时延业务的原则，为UE分配足量的1OFDM符号的短TTI资源。
图3为本发明实施例提供的又一种资源分配方法的流程图。在本发明实施例的另一种可能的实现方式中，同样在上述图1所示实施例的基础上，本实施例中的超低时延业务指示信息包括超低时延数据待传指示和超低时延指示值，则图1中的步骤S120可以包括：步骤S121，当超低时延数据待传指示为超低时延业务时，基站根据超低时延指示值分配对应长度TTI的上行超低时延资源；步骤S122，当超低时延数据待传指示为非超低时延业务时，基站分配上行非超低时延资源。本实施例中的步骤S121和步骤S122为择一执行的。
需要说明的是，本实施例中的超低时延数据待传指示为超低时延业务时，基站根据超低时延指示值分配对应长度TTI的上行超低时延资源与上述图2所示实施例中的分配方式相同，该超低时延指示值与上述实施例中的超低时延指示值的作用相同，基站可以根据该基站与UE所支持的TTI能力执行具体的分配操作，故在此不再赘述。
举例来说，同样以基站和UE都支持三种时长的TTI，具体为：1符号、0.5ms和1ms为例予以说明。基站接收到的SR消息中，超低时延数据待传指示可以为超低时延业务和非超低时延业务，在超低时延数据待传指示为超低时延业务时，超低时延指示值可以通过三个值来表示，如下表4所示。

超低时延数据待传指示和超低时延指示值 基站分配的资源类型
超低时延业务，超低时延指示值为1 TTI＝1符号
超低时延业务，超低时延指示值为2 TTI＝0.5ms
超低时延业务，超低时延指示值为3 TTI＝1ms
非超低时延业务 TTI＝1ms
需要说明的是，本实施例中的超低时延指示值越小，表示需要传输的数据量越小，越适合在短TTI上承载；另外，本实施例中超低时延指示值可以指示TTI的最大时长为目前通常使用的1ms时长的TTI，即可以与非超低时 延业务的TTI的时长相同。上述表4仅为本实施例给出的超低时延数据待传指示和超低时延指示值的组合与基站分配资源类型的一种可能的对应关系，本申请并不限制超低时延指示值的数量和其对应的TTI时长。并且，本实施例中的超低时延指示值同样可以为超低时延级别和/或超低时延业务的缓存数据量级别，本实施例在超低时延指示值为不同的内容时，基站分配短TTI的具体方式与上述实施例相同，故在此不再赘述。
可选地，在本申请上述各实施例的基础上，基站向UE发送的RRC连接建立消息中还可以配置有多载波业务，或单载波业务，或单载波业务和物理上行链路控制信道(Physical Uplink Control Channe，简称为：PUCCH)格式指示；在具体实现中，SR消息为UE根据基站和UE所支持的TTI能力，以及RRC连接建立消息中所配置的内容选择的对应扩展PUCCH格式所承载的，其中，所选择的扩展PUCCH格式中包括不小于2比特的SR消息指示值。
需要说明的是，在相关的LTE协议中：单载波业务的SR消息用PUCCH的Format 1或Format 1a来反馈；双载波业务的SR消息用PUCCH的Format 1b或Format 3来反馈；三载波或以上业务的SR消息用PUCCH的Format 3来反馈；其中，PUCCH的Format 3最多可以携带48个有效比特，而携带SR消息的PUCCH的Format 3目前使用到的比特情况为：频分双工(Frequency Division Dual，简称为：FDD)模式下Format 3最多支持11比特，其中，10比特用于传输混合自动重传请求-肯定确认指示(Hybrid Automatic Repeat request-ACKnowledgment，简称为：HARQ-ACK)，1比特用于正负SR指示；时分双工(Time Division Dual，简称为：TDD)模式下Format 3最多支持21比特，其中，20比特用于传输HARQ-ACK，1比特用于正负SR指示，1比特的正负SR指示中，1表示后续有数据需要传输，0表示后续没有数据需要传输。因此，对于不需要上报超低时延业务指示信息的应用场景，采用相关的PUCCH的Format的定义来上报SR消息。
本实施例以上述图2和图3所示实施例的情况予以示出，如上述表3和表4所示，超低时延指示值通过三个指示值来表示，通过PUCCH的格式扩展来承载携带超低时延业务指示信息的SR消息，例如通过对PUCCH的 Format 1b和Format 3的扩展来承载SR消息。
首先说明PUCCH的Format 1b和Format 3的扩展方式：
Format 1b最多支持3比特，其中，1比特用于传输HARQ-ACK，2比特用于传输SR消息，值为0表示负SR，值为非0表示正SR，且值为超低时延指示值。
FDD模式下Format 3最多支持12比特，其中，10比特用于传输HARQ-ACK，2比特用于传输SR消息，值为0表示负SR，值为非0表示正SR，且值为超低时延指示值。
TDD模式下Format 3最多支持22比特，其中，20比特用于传输HARQ-ACK，2比特用于传输SR消息，值为0表示负SR，值为非0表示正SR，且值为超低时延指示值。
需要说明的是，上述扩展PUCCH的Format 1b和Format 3中用2比特传输SR消息，是基于上述表3和表4中的超低时延业务指示信息的3种可能的TTI时长，若本发明实施例中超低时延指示值较多的情况下，需要通过扩展Format 3的更多比特来承载SR消息，例如采用3比特用于传输SR消息。基于上述对PUCCH格式的扩展，UE发送SR消息的具体方式可以为：
在基站和UE所支持的超低时延业务的TTI能力相同时，UE根据RRC连接建立消息中的配置选择扩展PUCCH格式，若配置了单载波业务，则可以采用Format 1b或Format3来承载SR消息，此时，若RRC连接建立消息中指示使用Format 1b上报SR消息，则采用Format 1b来承载SR消息，若未指示，则采用Format 3来承载SR消息；若配置了多载波业务，则可以采用Format 3来承载SR消息，并且具体根据上述FDD模式或TDD模式下的Format 3承载SR消息。
可选地，在本申请上述各实施例的基础上，基站向UE发送RRC连接建立消息中，还可以配置有多种PUCCH，在这种情况中，RRC连接建立消息还用于指示UE根据SR消息所指示的资源类型选择对应的PUCCH发送SR消息；举例来说，RRC连接建立消息中配置了第一PUCCH和第二PUCCH，第一PUCCH用于发送指示为上行超低时延资源的SR消息，第二PUCCH用 于发送指示为上行非超低时延资源的SR消息；本实施例中的上行非超低时延资源同样为TTI时长等于1ms的上行资源。
需要说明的是，本实施例中的UE采用第一PUCCH发送SR消息时，基站分配上行超低时延资源的方式与上述各实施例相同，同样是根据SR消息中的超低时延业务指示信息进行分配；若UE采用第二PUCCH发送SR消息时，则与相关技术中基站分配上行资源的方式相同。
图4为本发明实施例提供的再一种资源分配方法的流程图。本实施例提供的资源分配方法适用于UE获取上行资源的情况，该方法可以由资源分配装置执行，该资源分配装置通过硬件和软件结合的方式来实现，该装置可以集成在UE的处理器中，供处理器调用使用。如图4所示，本实施例的方法可以包括以下步骤：
步骤S210，UE向基站发送上行调度请求(SR)消息，该SR消息中包括超低时延业务指示信息，该SR消息用于指示基站根据SR消息中的超低时延业务指示信息为UE分配上行超低时延资源。
本实施例中的UE同样需要在SR周期内发送SR消息，并且SR周期同样是UE和基站建立RRC连接的过程中，基站为UE配置的，即本实施例在步骤S210之前，本实施例的方法还包括：步骤S200，UE接收基站发送的RRC连接建立消息，该RRC连接建立消息中配置有用于UE发送SR消息的资源和该资源对应的SR周期；相应地，UE向基站发送SR消息的具体方式为：UE根据RRC连接建立消息中配置的资源按照该资源对应的SR周期发送上述SR消息，其中，资源对应的SR周期配置为长度小于1ms的SR短周期；本实施例中，基站为UE配置的SR周期同样可以参照上述表2所示，在具体实现中，当UE从基站接收到SR的ISR值后可以进行判断，如果ISR值小于或等于157时，则认为配置了常规的SR周期，按常规SR周期策略发送SR消息；如果ISR值等于158，则认为配置了超低时延业务专用的SR短周期。
需要说明的是，本实施例中基站根据UE发送的SR消息分配上行资源的方式与上述各实施例相同，可选地，本实施例同样以SR消息的ISR值等于158为例予以说明，基站根据SR消息中的超低时延业务指示信息为UE分配上行超低时延资源，该情况中的SR消息不同于常规的SR消息，本实施例中 的SR消息在UE请求超低时延业务时，携带有超低时延业务指示信息，该超低时延业务指示信息例如可以包括超低时延数据待传指示、超低时延级别和超低时延业务的缓存数据量级别中的一项或多项，基站可以根据超低时延业务指示信息的具体形式和内容为UE分配上行超低时延资源。需要说明的是，常规上行资源中TTI时长为1ms，上行超低时延资源中TTI时长通常要小于1ms，例如可以为1符号，或0.5ms等。
本实施例提供的方法在实际应用中，还存在另一种可能的情况，即本实施例中的基站接收到UE发送的SR消息后，确定出SR消息中不包括超低时延业务指示信息，则可以根据该SR消息为UE分配上行非超低时延资源。该情况类似于常规方式，当SR消息中不包括超低时延业务指示信息时，未携带任何指示上行时延业务类型的信息，此时，基站直接分配上行非超低时延资源，该上行非超低时延资源通常为TTI时长等于1ms的上行资源。
步骤S220，UE接收基站分配的上行超低时延资源。
本实施例中，基站根据SR消息中的超低时延业务指示信息为UE分配的上行超低时延资源，从而向UE发送该分配的上行超低时延资源，即UE可以接收到该上行超低时延资源。
本实施例所提供的资源分配方法，UE通过向基站发送包括超低时延业务指示信息SR消息，指示基站根据SR消息中的超低时延业务指示信息为UE分配上行超低时延资源，从而UE可以接收到基站为其分配的上行超低时延资源；本实施例提供的方法实现了UE无需在等待基站为其分配上行资源后再向基站反馈超低时延业务指示，即在基站分配上行超低时延资源的过程中，减少了基站和UE交互的次数，相应地提高了基站分配上行超低时延资源的效率，解决了处于RRC连接态的UE在请求数据传输时，常规的SR消息无法指示超低时延业务需求信息的问题。
可选地，本实施例在基站与UE建立RRC连接的过程中，基站为UE配置的SR周期可以被配置为时长小于1ms的SR短周期，实现了UE在更短的间隔上发送SR消息，若当期时刻不是SR周期中的发送时刻，则等待更短的时间就可发送SR消息，提高了发送SR消息的时效性，即提高了获取上行超低时延资源的效率。
可选地，图4所示实施例中的超低时延业务指示信息例如包括超低时延数据待传指示，该超低时延数据待传指示用于指示UE当前是否有超低时延业务的数据等待传输；相应地，步骤S210中的SR消息用于指示基站在超低时延数据待传指示为超低时延业务时，为UE分配上行超低时延资源。
可选地，在上述图4所示实施例的基础上，本实施例中的超低时延业务指示信息包括超低时延指示值，则本实施例中的SR消息用于指示基站在确定出该基站与UE所支持的TTI能力相同时，根据超低时延指示值分配对应长度TTI的上行超低时延资源；或者，本实施例中的SR消息用于指示基站在确定出该基站与UE所支持的TTI能力不同时，根据基站与UE的TTI能力交集和超低时延指示值，优先分配超低时延指示值对应长度TTI的上行超低时延资源。本实施例以上述图2所示实施例中基站和UE支持的三种时长的TTI为例予以说明，即UE发送的SR消息中的超低时延指示值可以通过三个值来表示，如上述表3所示，并且基站根据超低时延指示值和基站与UE所支持的TTI能力分配上行超低时延资源的具体方式与图2所示实施例类似，故在此不再赘述。需要说明的是，本实施例中的超低时延指示值同样可以为超低时延级别或者超低时延业务的缓存数据量级别；其中，超低时延级别用于指示UE的超低时延业务对端到端时延的需求等级或UE的超低时延业务对调度时延的需求等级，超低时延业务的缓存数据量级别指示UE的缓存区内待传输的超低时延业务数据的总量或者UE的缓存区内待传输的最高优先级超低时延业务的数据量。
在上述实施例的基础上，本实施例中的超低时延业务指示信息还可以包括超低时延数据待传指示，则本实施例中的SR消息用于指示基站在超低时延数据待传指示为超低时延业务时，根据超低时延指示值分配对应长度TTI的上行超低时延资源；或者，本实施例中的SR消息用于指示基站在超低时延数据待传指示为非超低时延业务时，分配上行非超低时延资源。
需要说明的是，本实施例中SR消息可以包括上述超低时延数据待传指示、超低时延级别或者超低时延业务的缓存数据量级别的一项或多项，并且上述各项内容的格式，以及基站根据超低时延业务指示信息的不同内容分配上行超低时延资源的具体方式，上述实施例中已经具体说明，故在此不再赘 述。
可选地，图5为本发明实施例提供的还一种资源分配方法的流程图，在本发明上述各实施例的基础上，UE接收到的RRC连接建立消息中还可以配置有多载波业务，或单载波业务，或单载波业务和PUCCH格式指示；在具体实现中，在步骤S200之后，步骤S210之前，本实施例的方法还包括：步骤S201，UE根据基站和UE所支持的TTI能力，以及RRC连接建立消息中所配置的内容选择对应的扩展PUCCH格式来承载SR消息，其中，所选择的扩展PUCCH格式中包括不小于2比特的SR消息指示值。本实施例同样可以通过扩展PUCCH的Format 1b和Format 3来承载SR消息，扩展Format 1b和Format 3的具体方式与上述实施例相同，故在此不再赘述。
在具体实现中，基站和UE所支持的超低时延业务的TTI能力相同的情况下，UE选择扩展PUCCH格式的方式，即步骤S201包括：步骤S202，UE判断RRC连接建立消息中配置了多载波业务还是单载波业务，若为多载波业务，则执行步骤S203，若为单载波业务，则执行步骤S204。
步骤S203，UE采用扩展PUCCH的Format 3来承载SR消息；由于在FDD模式和TDD模式下，根据Format 3所支持的最大比特数不同，扩展Format 3的具体方式也根据具体的模式选择。
步骤S204，UE判断RRC连接建立消息中是否配置了PUCCH格式指示，若否，则执行步骤S203，若是，则执行步骤S205。
步骤S205，UE在PUCCH格式指示为指示使用Format 1b上报SR消息时，采用扩展PUCCH的Format 1b来承载SR消息，在PUCCH格式指示为指示使用Format 3上报SR消息时，采用扩展PUCCH的Format 3来承载SR消息；该扩展PUCCH的Format 1b和Format 3的比特使用情况与上述实施例相同。
需要说明的是，本实施例中扩展PUCCH的Format 1b和Format 3中用2比特传输SR消息，是基于上述表3和表4中的超低时延业务指示信息的3种可能的TTI时长，若本发明实施例中超低时延业务指示值较多的情况下，需要通过扩展Format 3的更多比特来承载SR消息，例如采用3比特用于传输SR消息。
可选地，在本发明上述各实施例的基础上，在步骤S200中，UE接收到的RRC连接建立消息中可以配置有多种PUCCH；则步骤S210可以替换为：UE根据SR消息所指示的资源类型选择对应的PUCCH发送SR消息，其中，第一PUCCH用于发送指示为上行超低时延资源的SR消息，第二PUCCH用于发送指示为上行非超低时延资源的SR消息；本实施例中的上行非超低时延资源同样为TTI时长等于1ms的上行资源。
需要说明的是，本实施例中的UE采用第一PUCCH发送SR消息时，基站分配上行超低时延资源的方式与上述各实施例相同，同样是根据SR消息中的超低时延业务指示信息进行分配；若UE采用第二PUCCH发送SR消息时，则与相关技术中基站分配上行资源的方式相同。
还需要说明的是，本发明上述实施例中的UE在发送SR消息时，在具有超低时延业务需求时均在该SR消息中携带有超低时延业务指示信息，以便基站在接收到该SR消息时，可以直接根据该超低时延业务指示信息为所述UE分配上行超低时延资源；在本发明实施例的另一种可能的实现方式中，可以通过其他方式指示UE具体的超低时延业务需求，如图6所示，为本发明实施例提供的一种资源分配方法的信令交互流程图，本实施例的方法包括以下步骤：
步骤S310，基站向UE发送RRC连接建立消息，该RRC连接建立消息中配置有PUCCH与时延需求指示值的对应关系，该RRC连接建立消息用于指示UE根据确定的时延需求指示值选择对应的PUCCH。
在本实施例中，基站在RRC建立消息中针对不同时长TTI的SR消息配置不同的PUCCH资源，举例来说，对于时延需求指示值为1的SR消息配置PUCCH1，对于时延需求指示值为2的SR消息配置PUCCH2，对于时延需求指示值为3的SR消息配置PUCCH3。
步骤S320，UE根据确定的时延需求指示值选择对应的PUCCH。
在本实施例中，UE发送SR消息时可以根据已确定时延需求指示值选择对应的PUCCH来发送，不同的时延需求指示值对应的TTI时长不同，UE确定的时延需求指示值即是确定所请求的TTI资源的时长。
步骤S330，UE通过所选择的PUCCH向基站发送SR消息。
举例来说，可以通过PUCCH1、PUCCH2或PUCCH3来发送SR消息，发送一次SR消息，只能通过一种PUCCH来承载，即图6中的三个步骤S330为择一选择的。
步骤S340，基站根据选择的PUCCH为UE分配对应长度TTI的上行资源，其中，上行资源包括上行超低时延资源和上行非超低时延资源。
在本实施例中，基站接收到SR消息后，可以根据PUCCH与不同时延需求指示值的对应关系来判断SR消息所请求资源的TTI时长，例如可以为各种TTI时长的超低时延业务，也可以为常规时延业务。
图7为本发明实施例提供的一种资源分配装置的结构示意图。本实施例提供的资源分配装置适用于为UE分配上行资源的情况，该资源分配装置通过硬件和软件结合的方式来实现，该装置可以集成在基站的处理器中，供处理器调用使用。如图7所示，本实施例的资源分配装置包括：接收模块11、分配模块12和发送模块13。
其中，接收模块11，设置为：接收UE发送的上行调度请求(SR)消息，其中，该SR消息中包括超低时延业务指示信息。
在本实施例中，UE通常需要在SR周期内发送SR消息，并且本实施例中的SR周期是UE和基站建立RRC连接的过程中，基站为UE配置的，即本实施例中的发送模块13，设置为：在接收模块11接收UE发送的SR消息之前，向UE发送无线资源控制(RRC)连接建立消息，其中，该RRC连接建立消息中配置有用于UE发送SR消息的资源和资源对应的SR周期，该RRC连接建立消息用于指示UE根据所配置的资源按照资源对应的SR周期发送SR消息，资源对应的SR周期配置为长度小于1ms的SR短周期。
需要说明的是，本实施例中基站为UE配置的资源，同样可以为上述表2中所示的SR短周期，当UE从基站接收到配置的资源后，根据资源判断SR周期的时长，并在确定出的SR周期内发送SR消息的方式与上述实施例相同，故在此不再赘述。
分配模块12，设置为：根据接收模块11接收的SR消息中的超低时延业 务指示信息为UE分配上行超低时延资源。
在本实施例中，SR消息不同于常规的不包括超低时延业务指示信息的SR消息，本实施例中的SR消息在UE请求超低时延业务时，携带有超低时延业务指示信息，该超低时延业务指示信息例如可以包括超低时延数据待传指示、超低时延级别和超低时延业务的缓存数据量级别中的一项或多项，分配模块12可以根据超低时延业务指示信息的具体形式和内容为UE分配上行超低时延资源。
本实施例提供的方法在实际应用中，还存在另一种可能的情况，即本实施例中接收模块11接收到的SR消息中可能没有携带超低时延业务指示信息，即常规的SR消息，则本实施例中的分配模块12，还设置为：在接收模块11接收UE发送的SR消息之后，在确定出接收模块11接收的SR消息中不包括所述超低时延业务指示信息后，根据SR消息为UE分配上行非超低时延资源。

可选地，图8为本发明实施例提供的另一种资源分配装置的结构示意图，在上述图7所示实施例的基础上，本实施例中的超低时延业务指示信息具体包括超低时延指示值，则本实施例中的分配模块12包括：判断单元14和分配单元15，判断单元14，设置为：判断基站与UE所支持的TTI能力是否相同；相应地，分配单元15，设置为：在判断单元14判断出基站与UE所支持的TTI能力相同时，根据超低时延指示值分配对应长度TTI的上行超低时延资源；在另一种可能的实现方式中，分配单元15，还设置为：在判断单元14判断出基站与UE所支持的TTI能力不同时，根据基站与UE的TTI能 力交集和超低时延指示值，优先分配超低时延指示值对应长度TTI的上行超低时延资源。需要说明的是，本实施例中的超低时延指示值同样可以为超低时延级别和/或超低时延业务的缓存数据量级别；其中，超低时延级别用于指示UE的超低时延业务对端到端时延的需求等级或UE的超低时延业务对调度时延的需求等级，超低时延业务的缓存数据量级别指示UE的缓存区内待传输的超低时延业务数据的总量或者UE的缓存区内待传输的最高优先级超低时延业务的数据量。

本发明实施例提供的资源分配装置用于执行图6所示实施例提供的资源分配方法中基站执行的操作，具备相应的功能模块，其实现原理和技术效果类似，此处不再赘述。
图9为本发明实施例提供的又一种资源分配装置的结构示意图。本实施例提供的资源分配装置适用于UE获取上行资源的情况，该资源分配装置通过硬件和软件结合的方式来实现，该装置可以集成在UE的处理器中，供处理器调用使用。如图9所示，本实施例的资源分配装置包括：发送模块21和接收模块22。

本实施例中的UE同样需要在SR周期内发送SR消息，并且SR周期同样是UE和基站建立RRC连接的过程中，基站为UE配置的，即本实施例中的接收模块22，还设置为：在发送模块21向基站发送SR消息之前，接收基站发送的RRC连接建立消息，其中，该RRC连接建立消息中配置有用于UE发送SR消息的资源和资源对应的SR周期；相应地，本实施例中发送模块21通过以下方式向基站发送SR消息：根据RRC连接建立消息中配置的资源按照资源对应的SR周期发送SR消息，其中，资源对应的SR周期配置为长度小于1ms的SR短周期。本实施例中基站为UE配置的资源，同样可以为上述表2中所示的SR短周期，当UE从基站接收到配置的资源后，根据资源判断SR周期的时长，并在确定出的SR周期内发送SR消息的方式与上述实施例相同，故在此不再赘述。
需要说明的是，本实施例中基站根据UE发送的SR消息分配上行资源的方式与上述各实施例相同，可选地，基站在接收到包括超低时延业务指示信息的SR消息中后，根据该超低时延业务指示信息为UE分配上行超低时延资源，本实施例中的SR消息在UE请求超低时延业务时，携带有超低时延业务指示信息，该超低时延业务指示信息例如可以包括超低时延指示值，或者包括超低时延数据待传指示、超低时延级别和超低时延业务的缓存数据量级别中的一项或多项，基站可以根据超低时延业务指示信息的具体形式和内容为UE分配上行超低时延资源。
本实施例提供的方法在实际应用中，还存在另一种可能的情况，即本实施例中的基站接收到的SR消息中可能并不包括所述超低时延业务指示信息后，此时，基站可以根据该SR消息为UE分配上行非超低时延资源。
接收模块22，设置为：接收基站分配的上行超低时延资源。
