实施例1
本发明实施例提供一种调度请求的发送方法，该方法应用于用户设备侧。图2是 本发明实施例1的调度请求的发送方法的示意图。如图2所示，该方法包括：
步骤201：从多个调度请求配置中选择一个调度请求配置；
步骤202：在选择的该调度请求配置对应的资源上发送调度请求。
在本实施例中，对于某个逻辑信道，当有新数据到达而目前没有资源发送该新数据时，则需要触发调度请求，即，该逻辑信道触发了调度请求。
在本实施例中，当触发了调度请求而未得到上行资源，例如上行共享信道(UL-SCH，Uplink Shared Channel)资源时，该调度请求被称为触发未决(pending)的调度请求。
在本实施例中，步骤201和步骤202可以由用户设备侧的介质访问控制(MAC，Media Access Control)层实体执行。
例如，对于每个传输时间间隔(TTI，Transmission Time Interval)或每个可能调度请求机会(每个TTI中的每个可能位置)，在当前TTI或当前调度请求机会，当没有用于传输的上行共享信道(UL-SCH，Uplink Shared Channel)资源时，MAC实体执行步骤201和步骤202。
在下一代通信系统中，每个逻辑信道可以对应一个或多个调度请求配置。
在本实施例中，该一个或多个调度请求配置可以是网络侧预先配置的，也就是说，该一个或多个调度请求配置所对应的资源是网络侧预先配置的。
以下针对每个逻辑信道对应一个调度请求配置的情况进行说明。
在本实施例中，当多个逻辑信道同时触发了调度请求时，多个逻辑信道对应于多个不同的调度请求配置。
在步骤201中，从多个调度请求配置中选择一个调度请求配置。以下对步骤201中选择调度请求配置的方法进行示例性的说明。
图3是本发明实施例1的调度请求配置的选择方法的示意图。如图3所示，该方法包括：
步骤301：在所有触发了调度请求的逻辑信道或所有具有上行待发送数据的逻辑信道中，选择具有最高优先级的逻辑信道所对应的调度请求配置；或者，
步骤302：在所有触发了调度请求的且具有有效的上行控制信道资源的逻辑信道或所有具有上行待发送数据且具有有效的上行控制信道资源的逻辑信道中，选择具有最高优先级的逻辑信道所对应的调度请求配置。
在步骤301中，选择具有最高优先级的逻辑信道所对应的调度请求配置，从而能够按照优先级的顺序选择调度请求配置。
在步骤302中，在具有有效的上行控制信道资源的逻辑信道中进行选择，能够有效减少数据发送所等待的时间。
在本实施例中，该上行控制信道资源例如是物理上行链路控制信道(PUCCH，Physical Uplink Control Channel)资源。
在本实施例中，例如，逻辑信道的优先级可以通过无线资源控制(RRC，Radio Resource Control)层的信令中逻辑信道配置(LogicalChannelConfig)单元中的优先级(priority)参数进行指示。
在本实施例中，该方法还可以包括：
步骤303：判断是否存在多个具有最高优先级的逻辑信道且该多个具有最高优先级的逻辑信道对应于多个调度请求配置，当判断结果为“是”时，进入步骤304-306中的一个，当判断结果为“否”时，结束进程；
步骤304：在该多个调度请求配置中，选择之前使用过的调度请求配置；或者，
步骤305：在该多个调度请求配置中，选择具有有效的上行控制信道资源的调度请求配置；或者，
步骤306：在该多个调度请求配置中，随机选择一个调度请求配置或通过用户设备自主决定的其他方式选择一个调度请求配置。
在步骤304中，选择之前使用过的调度请求配置，例如，选择在执行步骤201之前正在使用的调度请求配置，从而能够不改变正在使用的调度请求配置，另外，可以利用之前在使用该调度请求配置时保存的一些信息。
在步骤305中，选择具有有效的上行控制信道资源的调度请求配置，例如，选择具有有效的PUCCH资源的调度请求配置。这样，能够有效减少数据发送所等待的时间。
在本实施例中，当存在多个具有最高优先级的逻辑信道且该多个具有最高优先级的逻辑信道对应于多个调度请求配置时，不同于上述步骤304-306，该方法还可以包括：
在该多个调度请求配置中，选择该多个具有最高优先级的逻辑信道中具有最短时延要求的逻辑信道所对应的调度请求配置；或者，
在该多个调度请求配置中，选择该多个具有最高优先级的逻辑信道中具有最短的最大允许传输时间间隔(TTI)长度的逻辑信道所对应的调度请求配置；或者，
在该多个调度请求配置中，选择该多个具有最高优先级的逻辑信道中具有最大prioritisedBitRate参数的逻辑信道所对应的调度请求配置。
在步骤201选择了调度资源配置之后，在步骤202中，在选择的该调度请求配置对应的资源上发送调度请求。
在本实施例中，当选择的该调度请求配置与进行该选择之前正在使用的调度请求配置不相同时，该方法还可以包括：
将用于对调度资源配置进行计数的计数器SR_COUNTER置为0，或者，
将所选的调度资源配置的计数器SR_COUNTER置为之前所使用的调度资源配置的SR_COUNTER值。
在本实施例中，该方法还可以包括：当选择的该调度请求配置与进行该选择之前正在使用的调度请求配置相同时，将用于对调度资源配置进行计数的计数器加1。
例如，当MAC实体没有有效的PUCCH资源发送调度请求时，可以发起随机接入过程；当至少有一个有效的PUCCH资源对应所选择的调度请求配置，并且该PUCCH资源与任何测量间隔或边链路发现间隔都不冲突，并且所选调度请求配置对应的定时器sr-ProhibitTimer没有运行时，当SR_COUNTER小于所选择的调度请求配置的调度请求发送最大次数dsr-TransMax时，当选择的该调度请求配置与进行该选择之前正在使用的调度请求配置相同时，将SR_COUNTER加1，指示物理层在所选调度请求配置对应的PUCCH资源上，发送调度请求，并启动所选调度请求配置对应的定时器sr-ProhibitTimer。
以上主要针对每个逻辑信道对应一种调度请求配置的情况进行说明。
在本实施例中，对于每个逻辑信道对应多种调度请求配置的情况，该多个调度请求配置也可以对应于一个逻辑信道或一组逻辑信道，用户设备从多个调度请求配置中选择一个调度请求配置。
例如，当触发了调度请求的一个或一组逻辑信道对应于多个调度请求配置时，可以选择具有有效的上行控制信道(例如PUCCH)资源的调度请求配置，或者选择较短定时器sr-ProhibitTimer的调度请求配置，或者，选择之前使用过的调度请求配置。
由上述实施例可知，当有多个调度请求配置可以用来发送调度请求时，用户设备 从中选择一个调度请求配置，并在该调度请求配置对应的资源上发送调度请求，能够有效应对支持多种调度请求配置的通信机制。
实施例2
本发明实施例提供了一种参数配置方法，该方法应用于网络设备侧。图4是本发明实施例2的参数配置方法的示意图。如图4所示，该方法包括：
步骤401：向用户设备发送用于指示随机接入的退避时间的配置信息，该退避时间由网络侧根据随机接入过程而确定。
在本实施例中，例如，向用户设备发送用于指示没有成功接收随机接入响应(RAR)的用户设备在随机接入时使用的退避时间T的配置信息，用户设备在收到该配置信息后，在0～T的范围内随机选择一个时间值，在等待该时间值后再次发送随机接入请求。
在本实施例中，例如，该配置信息可通过MAC子头发送。
在本实施例中，该退避时间可以由网络侧根据不同的随机接入过程而确定，例如，可以根据随机接入的优先级而确定。
在本实施例中，该随机接入的优先级可以根据以下的至少一个而确定：随机接入的触发事件、上下行数据的业务优先级以及随机接入的失败次数。
例如，可以根据以下的公式(1)-(4)中的任一个来计算随机接入的优先级：
RA_priority＝a*x+b*y+c*z    (1)
RA_priority＝a*x+c*z        (2)
RA_priority＝a*x+b*y        (3)
RA_priority＝b*y+c*z        (4)
其中，RA_priority表示随机接入的优先级，a表示随机接入触发事件的权重，x表示随机接入触发事件的优先级；b表示上下行数据的业务优先级的权重，y表示上下行数据的业务优先级；c表示随机接入的失败次数的权重，z表示随机接入的失败次数。
在本实施例中，该配置信息包括至少两个用于指示退避时间的退避(B，backoff)指示字段，或至少两个用于指示退避时间的索引的退避索引(BI，backoff index)指示字段。
例如，该至少两个退避指示字段或至少两个退避索引指示字段用于指示至少两个 优先级的随机接入的退避时间或退避时间的索引。
以下，以该配置信息包括两个退避指示字段或两个退避索引指示字段为例进行说明。
例如，对于两种优先级的随机接入，该配置信息包括第一退避指示字段和第二退避指示字段，或第一退避索引指示字段和第二退避索引指示字段，第一退避指示字段或第一退避索引指示字段用于指示优先级较高的随机接入的退避时间或退避时间的索引，第二退避指示字段或第二退避索引指示字段用于指示优先级较低的随机接入的退避时间或退避时间的索引。
图5是本发明实施例2的发送该配置信息的MAC子头的示意图。如图5所示，该MAC子头包括字段E、字段T、第一退避索引指示字段BI1和第二退避索引指示字段BI2，字段E用于指示扩展字段，字段T用于指示是否包含随机接入ID或退避时间，字段BI1用于指示优先级较高的随机接入的退避时间的索引，字段BI2用于指示优先级较低的随机接入的退避时间的索引。
在本实施例中，该配置信息还可以包括一个用于指示退避时间的索引的退避索引指示字段。
在本实施例中，该退避时间的索引的每个取值对应于至少一个优先级的随机接入的退避时间，该退避时间分别指示该至少一个优先级的随机接入应采用的退避时间取值。
例如，表1是本发明实施例2的退避时间的索引表。如表1所示，对应于每一个索引的取值0～15，记录有三个优先级的随机接入的退避时间。
表1
Figure PCTCN2017096861-appb-000001
这样，通过该索引，就能够查找到对应于该索引数值的各个优先级的随机接入的退避时间。
在本实施例中，例如，该退避索引指示字段可以包括第一组比特和第二组比特，第一组比特用于指示优先级较高的随机接入的退避时间的索引，第二组比特用于指示优先级较低的随机接入的退避时间的索引。
图6是本发明实施例2的发送该配置信息的MAC子头的另一示意图。如图6所示，该MAC子头包括字段E、字段T、字段R和退避索引指示字段BI，字段E用于指示扩展字段，字段T用于指示是否包含随机接入ID或退避时间，字段R为保留字段，字段BI包括第一组比特和第二组比特，第一组比特用于指示优先级较高的随机接入的退避时间的索引，第二组比特用于指示优先级较低的随机接入的退避时间的索引。
在本实施例中，图5和图6所示的MAC子头的结构仅用于对该配置信息进行示例性的说明，本发明实施例不对该配置信息的具体形式进行限制。
以上，以该配置信息中包括退避指示字段或退避索引指示字段为例进行了说明，即退避时间是网络侧预先配置的。
在本实施例中，网络侧也可以不直接向用户设备配置退避时间。例如，该配置信息可以包括随机接入的优先级，以用于用户设备根据该优先级计算该退避时间。
例如，用户设备可以根据以下的公式(5)计算该退避时间：
T＝α*P       (5)
其中，T表示该退避时间，α表示时间系数，P表示随机接入的优先级。
在本实施例中，该时间系数α可以根据实际需要而设置。
由上述实施例可知，通过向用户设备配置由网络侧根据随机接入过程而确定的退避时间，能够有效应对支持多种随机接入配置的通信机制。
实施例3

图7是本发明实施例3的随机接入优先级的确定方法的示意图。如图7所示，该方法包括：
步骤701：根据以下的至少一个确定随机接入的优先级：随机接入的触发事件、上下行数据的业务优先级以及随机接入的失败次数。
在本实施例中，确定随机接入优先级的方法可以与实施例2中的记载相同。例如，可以使用以上的公式(1)-(4)中的任一个来计算随机接入优先级。
由上述实施例可知，通过确定随机接入的优先级，能够有效应对支持多种随机接入配置的通信机制。
