Description

随机接入方法、装置、设备、存储介质和程序产品
本申请要求于2017年9月30日提交中国国家知识产权局、申请号为201710938993.0、申请名称为“一种发起随机接入的方法”的中国专利申请的优先权，以及于2017年11月16日提交中国国家知识产权局、申请号为201711138282.1、申请名称为“随机接入方法、装置、设备、存储介质和程序产品”的中国专利申请的优先权，它们的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术，尤其涉及一种随机接入方法、装置、设备、存储介质和程序产品。
背景技术
第五代(5th Generation，5G)移动通信技术(mobile communication technology)是对第四代(the 4Generation，4G)移动通讯技术的延伸。因此，5G通信系统被称为“超4G网络”或“后长期演进(Long Term Evolution，LTE)系统”或者“新空口(New Radio，NR)”。在现有的LTE中，当发生调度请求失败(Scheduling Request，SR)failure时，用户设备(User Equipment，UE)进行随机接入，其具体过程可以对待3GPP TS 36.321中所描述的过程，UE向基站发送随前导码，接收基站返回的随机接入响应，并根据随机接入响应获取上行同步，以完成随机接入过程。
在NR中，UE可以被配置多个逻辑信道(Logical Channel，LCH)，当某个LCH上有数据需要发送时，如果UE没有可用的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)资源，可以触发UE在该LCH对应的SR配置(SR Configuration)的时频资源上发送SR消息。每个SR Configuration对应一个传输最大次数drs-TransMax。UE内部维持一个计数器SR_COUNTER。当UE的LCH上有数据且当前时隙或者传输时间间隔(Transmission Time Interval，TTI)中没有PUSCH资源时，会触发UE产生pending SR。若SR_COUNTER小于drs-TransMax时，则SR_COUNTER加1，并发送SR。SR或者SR bundle每发送一次就会使SR_COUNTER加1。当SR_COUNTER到达drs-TransMax时，UE认为发生SR失败SR failure。随后，UE将进行随机接入，目前NR中，UE使用触发SR failure的LCH对应的随机接入信道(Random Access Channel，RACH)配置来进行随机接入。其中随机接入配置包括UE进行随机接入的退避(backoff)参数和/或功率攀升(power ramping)参数。
然而，采用触发SR failure的LCH对应的RACH参数进行随机接入可能无法满足其他LCH上的业务的要求。

具体实施方式
UE的内部协议栈包含无线资源控制(Radio Resource Control，RRC)层、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、介质访问控制(Medium Access Control，MAC)层和物理(Physical，PHY)层，在PDCP层之上，还可以包含服务数据适应协议(Service Data Adaptation Protocol，SDAP)层。UE可以被配置多个LCH，当某个LCH上有数据需要发送时，如果UE没有可用的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)资源，可以触发UE在该LCH对应的SR配置SR Configuration的时频资源上发送SR消息。在现有的LTE中，如果UE发送SR消息达到传输最大次数drs-TransMax而仍没有被分配上行传输资源时，认为发生调度请求失败SR failure，进一步地，当发生调度请求失败SR failure时，UE释放所有的PUCCH资源，并进行随机接入，其具体过程可以参考3GPP TS 36.321中所描述的过程。
在NR中，UE可以被配置多个SR Configuration，每个SR Configuration对应一个传输最大次数，如drs-TransMax。UE内部针对每个SR Configuration配置一个计数器，记为SR_COUNTER。当UE的LCH上有数据需要发送且当前时隙或者传输时间间隔(Transmission Time Interval，TTI)中没有PUSCH资源时，会触发UE产生pending SR。当某一个或者多个SR Configuration对应的SR_COUNTER到达该SR Configuration对应的drs-TransMax时，UE认为发生SR失败SR failure。UE的一个或者多个LCH中有上行数 据需要发送给基站，但是UE没有被分配用于传输数据的PUSCH资源发送数据，UE需要向基站请求PUSCH资源。在UE没有被配置用于发送调度请求SR的上行资源的情况下，UE只能通过发起随机接入的方式(既发送随机接入前导(RA preamble))向基站请求PUSCH资源。在上述的SR失败或者UE没有被配置用于发送调度请求SR的上行资源，UE将进行随机接入，现有技术中提出使用触发SR failure的LCH对应的随机接入配置来进行随机接入。然而，如果有优先级更高的LCH上有数据，或者有更高的服务质量要求的业务数据待传输，那么直接采用触发SR failure的LCH对应的随机接入配置进行随机接入可能无法满足更高优先级的LCH的QoS要求。据此，本方案提供一种优化的随机接入方案，在UE出现SR失败时，使UE能够尽快完成随机接入，优先满足优先级较高的LCH或者QoS要求高的业务数据的传输，保证业务可靠性。
本申请可以应用于无线通信系统中，例如新空口(New Radio，NR)场景、LTE下一代场景、无线局域网(Wireless Local Area Network，WLAN)场景、蓝牙通信、3GPP定义的通信系统等场景中。为描述方便，实施例以新空口场景为例进行说明。图1为一种NR系统架构示意图，如图1所示，在NR场景中可以包含核心网，如NGC/5GC或者EPC，新空口的接入网，为描述方便，说明书中统一称为核心网、接入网。其中的功能实体主要为网络设备，及连接新空口接入网中的网络设备的用户设备，如图1所示的用户设备1，更多地，还可以包括中继设备及与中继连接的用户设备，如图1所示的用户设备2。中继设备与网络设备通过链路2建立连接，因此相对于网络设备，中继设备也可以视为一种用户设备；中继设备与用户设备2通过链路3建立连接，因此相对于用户设备，中继设备也可以视为一种网络设备。因此，本领域的技术人员可以理解，本申请中所述的网络设备也可以包含中继设备，本申请所述的用户设备也可以包含中继设备。其中，网络设备具体可以为gNB、新型无线电基站(New radio eNB)、传输点(transmission and reception point，TRP)、宏基站、微基站、高频基站、LTE宏或微eNB、用户驻地设备(Customer-premises equipment，CPE)、WLAN AP、WLAN GO等中的任一种或者某几种的组合，例如，网络设备可以为一个gNB，由该gNB完成本申请中网络设备所涉及的功能，或者，网络设备为gNB与TRP的组合，如由gNB完成本申请中网络设备的资源配置功能，由TRP完成本申请中网络设备的发送接收功能，本申请并不以此为限。用户设备可以为手机、平板、智能汽车、传感设备、物联网(Internet Of Things，IOT)设备、CPE、中继基站、UE、NR-UNIT等。
以上述图1所示的系统架构示意图为例，对本申请提供的随机接入方法进行说明，本方案中，如果UE没有被配置用于发送调度请求SR的上行资源或者UE发生调度请求失败，UE使用第一随机接入配置进行随机接入；
其中，所述第一随机接入配置为以下任一种：所述UE对应的第一LCH集合中优先级最高的LCH对应的随机接入配置；或者，所述UE对应的第一LCH集合所关联的随机接入配置中能够提供最高的服务质量(Quality of Service，QoS)的随机接入配置；或者，所述UE对应的第一SR配置集合中优先级最高的SR配置所对应的随机接入配置；或者，所述UE对应的第一SR配置集合所关联的随机接入配置中能够提供最高的QoS的随机接入配置。在该方案中，应理解UE对应的第一LCH集合包括UE内部拥有的LCH集合， 或者为UE配置的LCH集合，或者与该UE关联的LCH集合。同样的，UE对应的第一SR配置集合也包括UE内部拥有的SR配置集合，或者为UE配置的SR配置集合，或者与该UE关联的SR配置集合。对此本方案不做限制。
所述第一LCH集合包括所述UE的LCH中至少两个有上行数据需要发送的LCH；所述第一SR配置集合包括所述UE在发生所述SR失败后释放的SR配置中的至少一个。该方案中，
本方案中应理解，UE发生调度请求失败的情况包括：UE发生调度请求失败时，或者，UE发生调度请求失败之后等情况，对此本方案不做限制。
调度请求计数器可以是针对每个LCH进行配置的，也可以是针对每个SR配置进行配置的，无论是何种配置方式，当与该UE关联的任一个或者多个(或者全部)调度请求计数器的计数值达到预设的最大值，则确定UE发送SR失败。
上述方案中提供至少四种实现方式：
第一种实现方式，在UE没有被配置用于发送调度请求SR的上行资源或者UE确定发生SR失败进行随机接入时，选择的第一随机接入配置是UE配置的LCH中有数据要发送的多个LCH中，优先级最高的LCH对应的随机接入配置。所述有数据要发送可以为有上行数据要发送，或者有BSR需要发送，或者在MAC层对应的缓存中有缓存数据等情况。即UE根据LCH的优先级选择优选级高的LCH对应的随机接入配置进行随机接入，即优先保证优先级高的逻辑信道的业务，保证业务的可靠性。
对于UE来说，可以被配置多个LCH，每个LCH可用于不同的业务。每个LCH可配置相应的随机接入配置，该随机接入配置表明了针对该LCH进行随机接入请求上行资源时所使用的RACH参数，例如backoff参数、power ramping参数等。
第二种实现方式，在UE没有被配置用于发送调度请求SR的上行资源或者UE确定发生SR失败进行随机接入时，选择的第一随机接入配置是UE配置的LCH中有数据要发送的多个LCH所关联的RACH中，能够提供最高的QoS的随机接入配置。即UE根据有数据传输的LCH关联的所有RACH能够提供的QoS的高低确定选择哪个随机接入配置进行随机接入，本方案中选择能够提供最高的QoS随机接入配置进行随机接入，即优先保证服务质量要求最高的业务的可靠性。
第三种实现方式，在UE没有被配置用于发送调度请求SR的上行资源或者UE确定发生SR失败进行随机接入时，选择的第一随机接入配置为UE发生所述SR失败后释放的SR配置中优先级最高的SR配置所对应的随机接入配置。
该方案中，随机接入配置是与SR配置对应的，对UE的多个LCH来说，每个LCH可以对应0个或者1个SR配置。为每个SR配置对应的随机接入配置，因此UE在该实现方式中，选择优先级最高的SR配置对应的随机接入配置进行随机接入，优先保证优先级高的SR配置的业务传输，保证业务的可靠性。
应理解随机接入配置粒度的可以是与LCH一一对应的，也可以是与SR配置一一对应的。
第四种实现方式，在UE没有被配置用于发送调度请求SR的上行资源或者UE确定发生SR失败进行随机接入时，选择的第一随机接入配置为UE发生所述SR失败后释放 的SR配置中能提供最高QoS的SR配置所对应的随机接入配置。选择能够提供最高的QoS随机接入配置进行随机接入，即优先保证服务质量要求最高的业务的可靠性。
上述实施例提供的随机接入方法，如果UE没有被配置用于发送调度请求SR的上行资源或者UE发生调度请求失败，触发随机接入，UE根据上述方案选择合适的随机接入配置进行随机接入，能够尽快完成随机接入，并优先满足最高优先级的LCH或者最高QoS的要求，保证业务的可靠性。
在上述方案的基础上，可以理解，UE可以被配置多个SR配置(SR Configuration)和多个LCH。具体地，可以由网络设备，如gNB、cell、发送点和接收端(Transmission and Reception Point，TRP)等通过RRC消息或者MAC CE或者物理下行链路控制信道(Physical Downlink Control Channel，PDCCH)下行控制信息(Downlink Control Information，DCI)等方式向UE指示每个SR Configuration及LCH的配置信息，SR Configuration的配置信息可以包括某个SR Configuration的PUCCH时频资源、SR Configuration的drs_TransMax、sr_ProhibitTimer、SR Configuration对应Numerology、TTI时长等中的一种或者多种，进一步地，网络设备还可以配置该SR Configuration的优先级、该SR Configuration关联的随机接入配置(也称为随机接入配置信息，RACH配置等，对此本方案不做限制)。该随机接入配置可以为SR failure后进行随机接入时所使用的配置参数，例如，退避参数、功率信息等，具体地，退避参数可以包括UE在随机接入过程中接收随机接入响应(Random access response，RAR)后重发Preamble的退避时间区段，功率信息可以包括UE在重发前导码(Preamble)时所使用的发射功率攀升步长(PowerRampingStep)和/或初始传输功率等。
进一步地，随机接入配置还可以包括进行随机接入时使用的时频资源、Preamble传输最大次数、Preamble格式或长短信息、竞争解决计时器等中的一个或者多个。前述的随机接入配置中的配置参数可以在同一个消息中进行指示，也可以通过多次消息进行指示，例如，所述随机接入配置中的各项参数可以通过同一个RRC消息或者MAC CE或者PDCCH DCI等方式携带或者通过RRC信令或者MAC CE或者PDCCH DCI等方式中的两种或者两种以上的结合的方式携带。例如，所述功率信息可以通过RRC信令进行指示，而所述退避参数可以通过MAC CE携带的RAR进行指示。前述的随机接入配置中包含的所述配置参数可以通过显式或者隐式的方式进行指示。所述随机接入配置可以通过配置索引来携带，也可以通过直接描述携带，或者通过配置等级指示，或者通过优先级指示，或者通过前述方式中两种或者多种方式的结合方式携带。例如，通过将配置索引值与具体的配置参数进行对应，网络设备向UE指示所述随机接入配置时只携带相应的配置索引值，UE通过所述配置索引值来确定具体的随机接入配置中的配置参数；或者，将配置等级或者优先级指示与具体的配置参数进行对应，UE可以通过网络设备向其配置的配置等级或者优先级指示来确定具体的随机接入配置中的配置参数，举例说明，当SR Configuration被配置了一定的优先级时，当其接收到RAR后，可以结合RAR中指示的backoff indicator和自身的优先级确定该SR Configuration所对应的退避参数。
其中，LCH的配置信息可以包括LCH的优先级、该LCH对应业务信息等中的一种或者多种，进一步地，网络设备还可以配置该LCH关联的随机接入参数等，随机接入参数所具体包含的配置参数参考前述的描述。举例说明，当LCH被配置了一定的优先级时，当其接 收到RAR后，可以结合RAR中指示的backoff indicator和自身的优先级确定该LCH所对应的退避参数。
一个LCH可以映射到0个或者1个或者多个SR Configuration，即一个SR Configuration可以对应一个或者多个LCH。例如，在单载波场景下，一个LCH可以被映射到0个或者1个SR Configuration中。
在载波聚合(Carrier Aggregation，CA)场景下，一个LCH可以映射到多个Cell上的SR Configuration中，对于该LCH这多个cell上的SR Configuration可以称为一个SR Configuration集合或者SR Configuration Group，该SR Configuration Group可以被配置同一个drs_TransMax。对于该SR Configuration Group可以维持一个SR_COUNTER。UE在SR Configuration。Group内的任何一个SR Configuration上发送SR都会使SR_COUNTER加1。因此网络设备还可以向UE指示LCH与SR Configuration的映射关系，具体地，该映射关系可以在SR Configuration的配置信息或者LCH的配置信息中携带，或者通过其他配置信息携带，该映射关系可以通过RRC信令、MAC CE、DCI等方法中的一种或者多种进行指示，本申请不作限制。
前述的SR Configuration及LCH的配置信息可以通过显式或者隐式的方式进行指示，可以通过同一个RRC消息或者MAC CE或者PDCCH DCI等方式携带或者通过RRC信令或者MAC CE或者PDCCH DCI等方式中的两种或者两种以上的结合的方式携带。例如，在某些情况下，LCH的部分配置信息和SR Configuration的部分配置信息可以存在一定的关联关系，例如，SR Configuration的优先级可以通过其对应的LCH的优先级确定，例如，SR Configuration的优先级可以由其对应的LCH中优先级最高的一个来确定，或者SR Configuration的优先级可以由其对应的LCH中当前有数据的LCH中优先级最高的一个来确定，因此，网络可以不向其显式配置SR Configuration的优先级，其由其对应的LCH的优先级来隐式指示。
当UE在某个LCH上有上行数据要发送时，如果当前的传输时隙内没有可用的上行传输资源，如PUSCH资源，则可以触发SR，并在该LCH对应的SR Configuration的PUCCH资源发送SR，当前的传输时隙可以为TTI、slot、mini slot、frame、subframe等中的一种。具体地，当某个LCH上有数据要发送时，可以触发生成BSR，该BSR的类型可以为regular BSR或者padding BSR或者Periodic BSR等中的一种或者多种，当UE判定logicalChannelSR-ProhibitTimer没有运行且该BSR没有uplink grant时，触发SR。且在具体实施例中，应理解，文中的有待传输数据，有上行数据要传输，有数据要发送等描述均是相同的含义，可以为有上行数据要发送，或者有BSR需要发送，或者在MAC层对应的缓存中有缓存数据等情况。
在第一种可能的实施方式中，触发SR的LCH可以为该LCH对应的SR Configuration上最先有待传输数据的LCH，例如，在t0时刻，该SR Configuration所对应的LCH均没有待传输数据，在t1时刻，该SR Configuraiton对应的所有LCH中出现了第一个有待传输数据的LCH，则由该LCH触发SR，并使用该SR Configuration的PUCCH资源进行传输。
在第二种可能的实施方式中，触发SR的LCH可以为该LCH对应的SR Configuration所 对应的LCH中有待传输数据的优先级最高的LCH，例如，在t0时刻，该SR Configuration所对应的LCH均没有待传输数据，在t1时刻，该SR Configuraiton对应的所有LCH中出现了第一个有待传输数据的LCH，记为LCH1，由于LCH1为有待传输数据的优先级最高的LCH，因此由LCH1触发SR，在t2时刻，该SR Configuraiton对应的所有LCH中出现了第二个有待传输数据的LCH，记为LCH2，且LCH2优先级高于LCH1，则由LCH2触发SR该并使用该SR Configuration的PUCCH资源进行传输。
在第三种可能的实施方式中，触发SR的LCH可以该LCH对应的SR Configuration所对应的LCH中最后产生待传输数据的LCH，例如，在t0时刻，该SR Configuration所对应的LCH均没有待传输数据，在t1时刻，该SR Configuraiton对应的所有LCH中出现了第一个有待传输数据的LCH，记为LCH1，因此由LCH1触发SR，在t2时刻，该SR Configuraiton对应的所有LCH中出现了第二个有待传输数据的LCH，记为LCH2，则由LCH2触发SR，在t3时刻，该SR Configuraiton对应的所有LCH中出现了第三个有待传输数据的LCH，记为LCH3，则由LCH3触发SR该并使用该SR Configuration的PUCCH资源进行传输，依此类推。
当UE在SR Configuration的PUCCH资源上每发送一次SR或者SR bundle，会使SR_COUNTER加1。当SR_COUNTER达到drs_TransMax时，可以认为发生SR failure。具体地，根据不同的SR_COUNTER配置，发生SR failure可以有不同的定义：
例如，在第一种可能的实施方式中，如果SR_COUNTER是针对每个SR配置进行配置的，则UE的SR配置中任一SR配置中的SR计数器达到最大次数；或者，所述UE的SR配置中多个或者全部的SR配置中的SR计数器达到最大次数，则认为该UE发生SR failure。其含义是如果任意一个或者多个SR_configuration上的SR_COUNTER达到drs_TransMax，则认为发生SR failure；本领域的技术人员可以理解，SR_COUNTER达到drs_TransMax可能为SR_COUNTER等于drs_TransMax，也可能为SR_COUNTER超过或者大于drx_TransMax，其具体设定与设置的SR failure的判定标准有关，本申请实施例遵照该判定标准来定义SR_COUNTER达到drs_TransMax的具体含义。
在第二种可能的实施方式中，如果SR_COUNTER是针对每个SR configuration配置的，如果某一个或者多个或者全部的有待传输SR Pending SR的SR_configuration上的SR_COUNTER达到所述SR_COUNTER对应的SR Configuration的drs_TransMax，则认为发生SR failure；例如，当一个SR_COUTNER达到其对应的SR Configuration的drs_TransMax，若还有另一个有Pending SR的SR Configuration的SR_COUNTER未达到drs_TransMax，或者，有另外一个优先级更高的LCH触发的Pending SR的SR Configuration的SR_COUNTER未达到drs_TransMax，则可以继续发送SR而不进行随机接入，直到所述另一个有Pending SR的SR Configuration的SR_COUNTER达到drs_TransMax，则认为发生SR failure；需要说明的是，SR_COUNTER达到drs_TransMax的具体含义参考前述第一种可能的实施方式的描述。
在第三种可能的实施方式中，如果SR_COUNTER是针对MAC实体配置的，如果SR_COUNTER达到最后一个触发发送SR的LCH对应的SR Configuration的drs_TransMax，则认为发生SR failure；需要说明的是，SR_COUNTER达到drs_TransMax的具体含义参考前述第一种可能的实施方式的描述。
在第四种可能的实施方式中：如果SR_COUNTER是针对MAC实体配置的，如果SR_COUNTER达到所有触发pending SR的LCH中对应的SR Configuration的最小或者最大的drs_TransMax，则认为发生SR failure；需要说明的是，SR_COUNTER达到drs_TransMax的具体含义参考前述第一种可能的实施方式的描述。
在第五种可能的实施方式中，如果SR_COUNTER是针对UE配置的，如果SR_COUNTER达到最后一个触发发送SR的LCH对应的SR Configuration的drs_TransMax，则认为发生SR failure；需要说明的是，SR_COUNTER达到drs_TransMax的具体含义参考前述第一种可能的实施方式的描述。
在第六种可能的实施方式中：如果SR_COUNTER是针对UE配置的，如果SR_COUNTER达到所有触发pending SR的LCH中对应的SR Configuration的最小或者最大的drs_TransMax，则认为发生SR failure；需要说明的是，SR_COUNTER达到drs_TransMax的具体含义参考前述第一种可能的实施方式的描述。
需要说明的是，发生SR failure还可以有其他的定义，本申请不作限制。
如果发生SR failure，则基于第一随机接入配置发起随机接入过程。所述第一随机接入配置包括功率信息和退避参数中的至少一种。具体地，所述功率信息可以包括UE在重发Preamble时所使用的发射功率攀升步长PowerRampingStep和/或初始传输功率等，所述退避参数可以包括UE在随机接入过程中接收RAR后重发Preamble的退避时间区段，进一步地，所述第一随机接入配置还可以包括进行随机接入时使用的时频资源、Preamble传输最大次数、Preamble格式或长短信息、竞争解决计时器等中的一个或者多个。
所述基于第一随机接入配置发起随机接入过程可以为使用所述第一随机接入配置发起随机接入过程，具体地，可以为，在发起随机接入过程中发送和/或接收随机接入过程中的相关消息时采用所述第一随机接入配置中的配置参数，例如，当所述第一随机接入配置中包含发送preamble的PowerRampingStep时，UE在进行随机接入时，如果需要重发Preamble，则采用所述PowerRampingStep所指示的步长值，即重发Preamble的传输功率设置为前一次发送Preamble的传输功率加所述步长值；当所述第一随机接入配置中包含发送preamble的退避信息时，则在接收RAR后依据所述退避信息确定重发preamble的退避时间。
在不同的实施方式中，所述第一随机接入配置所表示的具体参数不同，具体地：
在第一种可能的实施方式中，所述第一随机接入配置为所述UE对应的第一LCH集合中优先级最高的LCH对应的随机接入配置。该方案确保有数据要传输的优先级最高的LCH的随机接入请求，保证了业务的可靠性。
在第二种可能的实施方式中，所述第一随机接入配置为所述UE对应的第一LCH集合所关联的随机接入配置中能够提供最高的服务质量QoS的随机接入配置。该方案确保了可以达到的最高的QoS完成SR failure触发的随机接入，保证了业务的可靠性。
具体地，所述第一LCH集合指的是UE对应的至少两个有上行数据需要发送的LCH，具体的包括以下情况：
所述UE的LCH中触发了SR的LCH，其含义是第一LCH集合包括UE配置的LCH中所有触发了SR的LCH。或者，
所述UE在发生所述SR失败后释放的SR配置所对应的LCH中有上行数据需要发送 的LCH。或者，
所述UE在发生所述SR失败后释放的SR配置所对应的LCH中触发了SR的LCH。或者，
触发发生所述SR失败的SR配置所在的小区/带宽片段BWP上配置的SR配置所对应的LCH中有上行数据需要发送的LCH。或者，
触发发生所述SR失败的SR配置所在的小区/BWP上配置的SR配置所对应的LCH中触发了SR的LCH。或者，
所述UE的所有服务小区上的SR配置所对应的LCH中有上行数据需要发送的LCH。或者，
所述UE的所有服务小区上的SR配置所对应的LCH中触发SR的LCH。或者，
触发发生所述SR失败的SR配置所对应的LCH中有上行数据需要发送的LCH。
上述方案中，应理解，如果UE发生SR失败，则该第一LCH集合种至少包括触发了SR失败的LCH。另外，释放的SR Configuration可以为触发发生SR failure的SR Configuration或者触发发生SR failure的的SR Configuration所在的小区(cell)/带宽片段(bandwidth part，BWP)上配置的SR Configuration或者所有服务小区(serving cell)上的SR Configuration等，本申请不作限制。因此，使用第一随机接入配置进行随机接入可以满足UE的第一LCH集合中优先级最高的LCH的QoS要求，保证了业务的可靠性。
本领域的技术人员可以理解，随机接入配置的QoS等级可以通过该随机接入配置的配置参数来确定，例如，退避参数指示的退避时间更短和/或功率信息指示的PowerRampingStep更大，可以推断出该随机接入配置的配置参数进行随机接入过程时的QoS等级更高；或者，随机接入配置的QoS等级可以通过该随机接入配置中包含的等级指示信息来确定，如下表所示：
Figure PCTCN2018107789-appb-000001
网络设备可以对应随机接入配置指示相应的优先级排序Priority Order，因此，UE可以确定所述第一LCH集合中所关联的随机接入配置中Priority Order最靠前的随机接入配置作为所述第一随机接入配置。
因此，使用所述第一随机接入配置进行随机接入可以应用所述用户设备的第一LCH集合中关联的可以提供最高QoS的随机接入配置，尽可能地保证了业务的可靠性。
在第三种可能的实施方式中，所述第一随机接入配置为所述UE的第一SR配置集合中优先级最高的SR Configuration所关联的随机接入配置。
在第四种可能的实施方式中，所述第一随机接入配置为所述UE的第一SR配置集合中所关联的能提供最高QoS等级的随机接入配置。
具体地，所述第一SR配置集合包括所述UE在发生所述SR失败后释放的SR配置中的至 少一个，具体包括以下情况：
所述UE的所有SR配置；或者，
触发了SR的SR配置；或者，
有待传输数据的SR配置；或者，
触发发生所述SR失败的SR配置；或者，
发生调度请求失败的SR配置；或者，
触发发生所述调度请求失败的SR配置所在的小区/BWP上配置的SR配置。
上述几种情况的具体实现中，若所述第一SR Configuration集合为所述UE在发生所述SR failure后释放的SR Configuration，具体地，所述释放的SR Configuration可以为触发发生SR failure的SR Configuration或者触发发生所述SR failure的的SR Configuration所在的cell/BWP上配置的SR Configuration或者所有serving cell上的SR Configuration等，本申请不作限制。
若所述第一SR Configuration集合为触发发生所述SR failure的SR Configuration，具体地，触发发生所述SR failure的SR Configuration可以为最后一个发送SR的SR Configuration或者为第一个发送SR的SR Configuraion，或者触发SR_COUNTER达到drs_TransMax的SR所在的SR Configuration，或者触发SR_COUNTER开始加1的SR所在的SR Configuration，或者使得SR_COUNTER加1的SR所在的SR Configuration等，本申请不作限制。
若所述第一SR Configuration集合为发生SR failure的SR Configuration，具体地，发生SR failure的SR Configuration可以为需要被释放的SR Configuration，或者触发发生SR failure的SR Configuration，或者触发发生SR failure的SR Configuration所在的cell/BWP上其对应LCH上有待传输数据的SR Configuration，或者触发发生SR failure的SR Configuration所在的cell/BWP上其对应LCH上有待传输SR的SR Configuration，或者触发发生SR failure的SR Configuration所有的/BWP上所有的SR Configuration，或者UE的所有serving cell上的所有SR Configuration等，本申请不作限制；

通过上述方式，使用所述第一随机接入配置进行随机接入可以满足所述用户设备的第一SR Configuration集合中优先级最高的SR Configuration的QoS要求，保证了业务的可靠性。
因此，使用所述第一随机接入配置进行随机接入可以应用所述用户设备的第一SR Configuration集合中关联的可以提供最高QoS的随机接入配置，尽可能地保证了业务的可靠性。
在上述方案的基础上，下面以以具体实例对本申请提供的随机接入方法进行说明。
图2为本申请提供的UE发生调度请求失败进行随机接入的示意图；如图2所示，假设UE被配置了LCH1和LCH2，其中LCH1用于eMBB业务，LCH2用于URLLC业务。LCH2的优先级大于LCH1的优先级，且两LCH上均有业务数据待传输，触发了调度请求。LCH1上的SR发送多次，仍未接收到网络设备的响应，且SR计数器达到了预设的最大值，触发了UE的SR失败，UE发起随机接入，根据前述的技术方案，UE可选择 使用优先级更高的LCH2对应的随机接入配置进行随机接入。如果还有比LCH2优先级更高的LCH上有待传输数据，如LCH3，则使用LCH3所对应的随机接入配置作为进行随机接入的随机接入配置。
可选的，根据前述方案，如果UE释放了SR配置1和SR配置2对应的PUCCH资源，且LCH2的优先级高于LCH1，因此确定LCH2对应的随机接入配置作为进行随机接入的随机接入配置。如果还有比LCH2优先级更高的LCH上有待传输数据，如LCH3，但是LCH3所对应的SR配置的PUCCH资源没有被释放，则可以仍然使用LCH2所对应的随机接入配置作为进行随机接入的随机接入配置。
可选的，根据前述方案，如果仅有LCH1和LCH2触发了SR，且LCH2的优先级高于LCH1，因此确定LCH2对应的随机接入配置作为进行随机接入的随机接入配置。如果还有比LCH2优先级更高的LCH上有待传数据，如LCH3，若LCH3也会触发pending SR，则可以使用LCH3所对应的随机接入配置作为进行随机接入的随机接入配置。若LCH3不触发pending SR，则可以仍然使用LCH2所对应的随机接入配置作为进行随机接入的随机接入配置。
可选的，根据前述方案，如果UE释放了SR配置1和SR配置2对应的PUCCH资源，且LCH2的优先级高于LCH1，因此确定LCH2对应的随机接入配置作为进行随机接入的随机接入配置。
除此之外，UE还可以选择能够提供最高QoS的随机接入配置作为进行随机接入的随机接入配置，具体方案参考前述描述，在此不再赘述。
本实例提供的随机接入方法，实现了UE保证优先级较高的LCH进行随机接入，即保证了LCH的业务要求，提高了业务的可靠性。
