本发明实施例提供的调度请求处理方法的另一种可选处理流程,如图3所示,包括以下步骤:
步骤S301,网络设备为不同的逻辑信道或不同的业务配置SR参数和SR资源,并将所述SR参数和SR资源通知终端设备。
可选地,所述SR参数为以下至少之一:SR ID,Scheduling Request Id,SR configuration ID。
步骤S302,终端设备根据网络设备的指示确定以下信息至少之一:对应的逻辑信道、业务SR、SR资源、SR和SR资源的对应关系,SR和SR对应的资源。
步骤S303,在第二SR未配置有效的PUCCH资源或达到SR最大传输次数时,终端设备的MAC实体执行下述操作。
可选的,MAC对第一SR和/或第二SR分别处理。
A、在第二SR未配置有效的PUCCH资源时,MAC实体执行下述操作中的任意一种:
1)MAC实体触发第二SR对应的随机接入过程。
2)MAC实体取消所述第二SR。
3)MAC实体触发第二SR对应的随机接入过程,并且取消所述第二SR。
4)当存在第一SR,且第二SR触发的物理信道与第一SR的资源重叠时,MAC实体取消所述物理信道,或者所述MAC实体取消所述第二SR触发的随机接入过程,或者所述MAC实体不触发所述第二SR对应的随机接入过程,或者所述MAC实体延迟触发所述第二SR触发的随机接入过程,或者所述MAC实体延迟所述第二SR触发的随机接入过程。
5)当存在第一SR时,所述MAC实体延迟触发所述第二SR对应的随机接入过程或者,在第一SR对应的PUCCH资源之后的时刻触发第二SR对应的随机接入过程。。
B、达到SR最大传输次数时,MAC实体执行下述操作中的任意一种:
1)MAC实体触发第二SR对应的随机接入过程。
2)MAC实体取消第一SR以外的所有待传输SR。
3)MAC实体触发第二SR对应的随机接入过程,并且取消第一SR以外的所有待 传输SR。相关技术中,当达到SR最大传输次数时,MAC实体取消所有待传输SR。而针对R16来说,支持区分优先级低的业务(如eMBB)触发的SR与优先级高的业务(如URLLC)触发的SR;此时,若eMBB业务触发的SR传输达到最大重传次数,仍取消URLLC业务触发的SR,将导致网络不能及时获知URLLC业务需要传输,导致调度延迟,以及URLLC业务的QoS不能够满足的问题;本发明实施例通过对SR进行区别处理,使得在SR达到最大重传次数时,仍旧不取消第一SR(URLLC业务对应的SR)的重传,使得网络设备能够及时获知URLLC业务需要传输,避免调度延迟,以及URLLC业务的QoS不能够满足的问题。
可选地,在第二SR未配置有效的PUCCH资源或达到SR最大传输次数或在第二SR配置有效的PUCCH资源或小于SR最大传输次数时,终端设备的MAC实体执行下述操作:
C、终端设备的MAC实体还向物理层发送第一指示信息,所述第一指示信息用于指示物理信道的传输信息。
可选地,在第一SR未配置有效的PUCCH资源或达到SR最大传输次数或在第一SR配置有效的PUCCH资源或小于SR最大传输次数时,终端设备的MAC实体执行下述操作:
终端设备的MAC实体还向物理层发送第一指示信息,所述第一指示信息用于指示物理信道的传输信息或UCI的传输信息。
由于所述物理信道的传输信息包括物理信道传输的优先级、抢占信息、对应的业务信息、数据信息、和逻辑信道信息中的至少一项,使得第二SR触发的随机接入过程对应的物理信道与其他信道冲突时,物理层能够确定优先发送所述物理信道还是其他信道;当其他信道传输的是优先级高的业务对应的逻辑信道时,如URLLC业务对应的逻辑信道,则优先传输URLLC业务对应的逻辑信道;而第二SR触发的随机接入过程对应的物理信道或者被取消,或者在URLLC业务对应的逻辑信道传输之后进行传输。本发明实施例通过第一指示信息,使得物理层能够根据第一指示信息指示的优先级发送相应的信道、UCI、以及优先发送所述物理信道还是其他信道;如此,网络设备能够及时获知优先级高的业务(如URLLC)需要传输,避免调度延迟,以及优先级高的业务(如URLLC)的QoS不能够满足的问题。
需要说明的是,本发明实施例中针对所述第一SR、所述第二SR、所述第一指示信息的说明与上述实施例的相关说明相同,这里不再赘述;上述操作C可以单独执行,即执行操作C时,不执行操作A和操作B;操作C也可以与操作A、操作B结合,即执行操作A和操作C,或者执行操作B和操作C,或者执行操作A、操作B和操作C。
可选的,所述MAC实体指示物理层传输或生成传输时,所述MAC实体向物理层发送所述第一指示信息;或者,混合自动重传请求HARQ实体请求传输时,所述MAC实体或其功能实体(如HARQ实体)向物理层发送所述第一指示信息;或者,从混合自动重传请求HARQ获取传输信息时,所述MAC实体或其功能实体(如HARQ实体)向物理层发送所述第一指示信息;或者,所述终端设备进行Grand传输时,所述MAC实体向物理层发送所述第一指示信息。所述第一指示信息用于指示物理层传输上行授权的相关信息,如:是否能够传输上行授权,或是否优先传输上行授权,上行授权是否被抢占或抢占其他物理信道的传输,或如何传输上行授权,或是上行授权的优先级信息,或是上行授权的对应的业务/逻辑信道/MAC CE优先级信息,或是上行授权的对应的业务/逻辑信道/MAC CE标识信息等。
可选的,所述MAC实体根据网络指示或物理层指示,或在收到网络指示或物理层指示后,向物理层发送所述第一指示信息。如在收到网络指示或物理层指示后,混合自 动重传请求HARQ实体请求传输时,所述MAC实体或其功能实体(如HARQ实体)向物理层发送所述第一指示信息。又如在收到网络指示或物理层指示后,所述MAC实体执行针对所述第一SR、所述第二SR、所述第一指示信息的操作。
下面基于不同的场景对本发明实施例提供的调度请求处理方法的处理过程进行说明。
