  • terminal devices In a communication system, when a terminal device needs to send uplink data to the network side (network device), the terminal device needs to use uplink resources to send uplink data. If the terminal device does not have uplink resources, it needs to apply for uplink resources from the network device.
  • terminal devices can apply for uplink resources from network devices in the following three ways:
  • the terminal device can insert a BSR control unit in the protocol data unit (PDU) of the media access control (media access control, MAC) layer to notify the network device: one or several logical channel groups ( How much data currently needs to be sent in the logical channel group (LCG), requires the network device to allocate some uplink resources to the terminal device.

  • MAC media access control
  • one LCG includes multiple LCHs, and the LCHs are used for the data transmission service of the MAC layer, and the MAC layer can map the LCHs to a transmission channel, so as to transmit the data to be transmitted on the LCHs.
  • the network device When the network device receives the BSR sent by the terminal device, it will send a UL grant to the terminal device, which is used to indicate the uplink resource allocated by the network device to the terminal device, including the location of the uplink resource, modulation and coding scheme (molation and coding scheme, MCS) and other related information about uplink resources.
  • MCS modulation and coding scheme
  • This method of applying for uplink resources by sending a BSR can let the network device know the amount of data that the terminal device needs to send, so that uplink resources can be allocated in a targeted manner. But there is a problem here, because the BSR is encapsulated in the MAC PDU and sent to the network device through the physical uplink shared channel (PUSCH), so the action of the terminal device to send the BSR itself also requires uplink resources. If the terminal device does not have any uplink resources and cannot send a BSR, then the terminal device needs to apply for uplink resources from the network device in the following way.
  • PUSCH physical uplink shared channel
  • SR scheduling request
  • the terminal device cannot send BSR to apply for uplink resources, it can apply for uplink resources by sending SR.
  • SR can be transmitted in the physical uplink control channel (PUCCH) and can be sent to the network without uplink resources. equipment.
  • the SR only tells the network device that there is uplink data to be sent, but does not tell the network device how much uplink data the terminal device has to send.
  • the network device does not know how much uplink resources should be allocated, so the subsequent terminal device may still need to send a BSR to apply for more (or additional) uplink resources.
  • how many uplink resources to allocate is determined by the algorithm of the network device manufacturer. Generally speaking, after the network device receives the SR, the allocated uplink resource can at least satisfy the sending of the BSR.
  • the solution of the embodiment of the present application mainly involves the manner in which the terminal device sends a BSR to the network device to apply for uplink resources.
  • the terminal equipment allocates uplink resources:
  • the terminal equipment After the network device allocates uplink resources to the terminal equipment, the terminal equipment allocates uplink resources to the uplink data to be transmitted on the LCH according to the priority of the LCH. Different LCHs have different priorities, and the data on the LCH with higher priority will be prioritized. Send through uplink resources.

  • the terminal device sends the BSR to the network device based on the LCG, but there is no direct correspondence between the LCG based on which the BSR reported by the terminal device is based and the uplink resources allocated by the network device.
  • the uplink resources allocated to the terminal device by the network device according to the BSR are not necessarily allocated by the terminal device to the uplink data on the LCH in the one or several LCGs. Instead, it is allocated according to the priority of the LCH. In other words, whether the uplink data on a certain LCH can be allocated uplink resources by the terminal device has no corresponding relationship with whether the terminal device sends a BSR based on the LCG to which the LCH belongs.
  • the terminal device only allocates uplink resources for the data on the LCH according to the priority of the LCH, the data on the LCH with a lower priority may not be sent out for a long time.
  • PBR prioritized bit rate
  • the data corresponding to the PBR can be understood as the data to be transmitted preferentially within a unit time among the data to be transmitted on a certain LCH.
  • the terminal device When the terminal device allocates uplink resources for the data to be transmitted on each LCH, it will first allocate uplink resources for the data corresponding to the respective PBRs of each LCH, and then allocate uplink resources for the remaining data on each LCH except the data corresponding to the respective PBRs Allocation of uplink resources provides a minimum data transmission rate guarantee for each LCH.
  • the PBR of the LCH is configured by the network device through RRC signaling.
  • the terminal device has three LCHs in total: LCH1, LCH2 and LCH3, corresponding to PBR1, PBR2 and PBR3 respectively, and the order of priority of these three LCHs is LCH1>LCH2>LCH3.

After the terminal device allocates uplink resources for the part of data corresponding to PBR3 in LCH3, if there are still remaining uplink resources, then allocate the remaining uplink resources to LCH1 with the highest priority, excluding the part of data corresponding to PBR1 ( Data 4). In addition, although it is not shown in FIG. 1 , if there are remaining uplink resources, the terminal device will allocate the remaining uplink resources to the LCH2 with the second highest priority, excluding some data corresponding to PBR2.

After receiving this part of P frame data and BSR, the network device sends UL grant to the terminal device.

Description

上行数据传输方法、网络设备、终端设备及通信系统
本申请要求于2022年01月10日提交国家知识产权局、申请号为202210023616.5、申请名称为“一种避免数据超时的方法、UE及网络设备”的中国专利申请的优先权,以及于2022年02月18日提交国家知识产权局、申请号为202210152343.4、申请名称为“上行数据传输方法、网络设备、终端设备及通信系统”的中国专利申请的优先权,其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领域,尤其涉及上行数据传输方法、网络设备、终端设备及通信系统。
背景技术
扩展现实(extended reality,XR)业务中的视频帧分为I帧和P帧。其中,I帧是一个全帧压缩编码帧,包含整帧的图像信息。P帧为前向预测编码帧,表示的是这一帧与前一帧的差值,即解码P帧需要参考前一帧的相关信息。在传输视频时,编码器将组成视频的多张图像进行编码后产生一段一段的画面组(group of pictures,GOP),GOP是一组连续的画面,由一个I帧和数个P帧组成。终端设备运行XR业务时,若终端设备需要传输视频,终端设备需要在配置的包时延预算(packet delay buget,PDB)内,向网络设备传输完一帧的数据,从而使网络设备可以及时地向云端传输收到的帧数据,让云端正确解码。如果在PDB内终端设备没有传输完这一帧的数据,终端设备会丢弃这一帧剩余的待传数据。
发明内容
通信系统中,终端设备侧不同的待传输上行数据可以对应不同的逻辑信道(logical channel,LCH),终端设备发送LCH上的上行数据时,需要先为LCH上的上行数据分配上行资源,再通过分配的上行资源发送LCH上的上行数据。具体地,终端设备需要通过缓存状态报告(buffer status report,BSR)通知网络设备,终端设备的上行缓存(buffer)里有多少数据要发送,以便让网络设备知道要给终端设备分配多少上行资源。当网络设备收到终端设备发送的BSR后,会根据BSR给终端设备发送上行授权(UL grant),用以指示为终端设备分配的上行资源的位置等信息,终端设备收到UL grant后,可以根据网络设备分配的上行资源,为待发送的LCH上的上行数据分配上行资源,再将待发送的LCH上的上行数据发送给网络设备。
但是,按照BSR触发机制,终端设备运行XR业务时,若LCH上存在I帧数据和/或P帧数据需要传输给网络设备,可能会导致某帧的数据无法在配置的PDB内传输完成,甚至无法传输,进而导致网络设备无法及时向云端传输完整的帧数据,云端无法正确解码帧数据,严重影响用户体验。因此,如何保障终端设备可以完整传输帧数据,是亟待解决的问题。
本申请实施例提供一种上行数据传输方法、网络设备、终端设备及通信系统,用于解决终端设备无法完整传输帧数据的问题。为了解决上述的技术问题,本申请的实 施例采用如下技术方案:
第一方面,提供了一种上行数据传输方法。执行该方法的通信装置(主体)可以为网络设备也可以为应用于网络设备中的模块,例如芯片。下面以执行主体为网络设备为例描述。该方法包括:网络设备接收来自终端设备的第一信息,第一信息用于指示终端设备待传输的第一上行数据的数据量。网络设备根据第一信息确定第一上行资源。网络设备接收来自终端设备的第二信息,第二信息用于指示与第一上行数据对应的第一时长。若网络设备根据第一上行数据的数据量和第一时长,确定终端设备能够在第一时长内发送第一上行数据至网络设备,且确定终端设备在接收第一指示信息之前存在第二上行数据待传输,网络设备向终端设备发送第一指示信息和第二指示信息。第一指示信息用于指示第一上行资源的信息。第二指示信息用于指示以下的至少一项:终端设备在第一上行资源上优先发送第一上行数据;或者,终端设备提高第一上行数据对应的第一逻辑信道的优先比特率。
基于本申请实施例的技术方案,网络设备在收到终端设备发送的指示第一上行数据的数据量的第一信息,以及与第一上行数据对应的第一时长后,若确定终端设备在收到分配的第一上行资源期间有新的第二上行数据待传输,为了避免为终端设备分配的第一上行资源被终端设备过多地用于传输第二上行数据,导致出现第一上行资源不足以传输完第一上行数据的情况,网络设备可以通过第二指示信息指示终端设备在第一上行资源上优先发送第一上行数据,和/或,提高第一上行数据对应的第一逻辑信道的优先比特率,从而保证终端设备可以在第一上行资源上完整发送第一上行数据,避免出现第一上行数据传输超时,导致无法正确解码数据,影响用户体验的情况。
结合上述第一方面,在一种可能的设计中,在网络设备向终端设备发送第一指示信息和第二指示信息之前,第一优先级低于第二优先级。第一优先级为第一上行数据对应的第一逻辑信道的优先级,第二优先级为第二上行数据对应的第二逻辑信道的优先级。本申请实施例的技术方案可以应用于第一优先级低于第二优先级的场景中,从而解决若第一优先级低于第二优先级,可能会导致未传完的第一上行数据无法在配置的PDB内传完的问题。
结合上述第一方面,在一种可能的设计中,第一逻辑信道为前向预测编码帧对应的逻辑信道;第二逻辑信道为全帧压缩编码帧对应的逻辑信道。在网络设备向终端设备发送第一指示信息和第二指示信息之前,该方法还包括:网络设备确定第一上行数据为前向预测编码帧,第二上行数据为全帧压缩编码帧。本申请实施例的技术方案可以应用于前向预测编码帧对应的逻辑信道配置的优先级,低于全帧压缩编码帧对应的逻辑信道配置的优先级的场景中,从而解决XR业务中,未传完的全帧压缩编码帧数据可能无法在配置的PDB内传完的问题。
结合上述第一方面,在一种可能的设计中,第二指示信息用于指示终端设备在第一上行资源上优先发送第一上行数据包括:第二指示信息用于指示终端设备将第一优先级调整为第三优先级,其中,第三优先级高于第二优先级。基于本申请实施例的技术方案,终端设备可以根据第二指示信息调整第一上行数据对应的逻辑信道原先的优先级,使调整后的第一上行数据对应的逻辑信道的优先级,高于第二上行数据对应的逻辑信道的优先级。因为终端设备会优先传输优先极高的逻辑信道上的上行数据,所 以终端设备会在第一上行资源上优先发送第一上行数据。
结合上述第一方面,在一种可能的设计中,在第二指示信息用于指示终端设备提高第一上行数据对应的第一逻辑信道的优先比特率的情况下,第二指示信息还用于指示终端设备降低第二上行数据对应的第二逻辑信道的优先比特率。基于本申请实施例的技术方案,可以提高第一逻辑信道的优先比特率且降低第二逻辑信道的优先比特率,实现使第一上行资源更多地分配给第一上行数据,更少地分配给第二上行数据。
结合上述第一方面,在一种可能的设计中,第二指示信息用于指示终端设备在第一上行资源上优先发送第一上行数据包括:第二指示信息用于指示第一上行资源仅能用于传输第一逻辑信道对应的上行数据。其中,第一上行数据对应第一逻辑信道,第二上行数据对应第二逻辑信道。基于本申请实施例的技术方案,终端设备可以根据第二指示信息,仅将第一上行资源分配给第一逻辑信道上的第一上行数据,不会将第一上行资源分配给第二逻辑信道上的第二上行数据,从而实现在第一上行资源上优先发送第一上行数据。
结合上述第一方面,在一种可能的设计中,网络设备确定终端设备在接收第一指示信息之前,存在第二上行数据待传输,包括:网络设备获取终端设备向网络设备发送的上行数据的周期信息;网络设备根据周期信息,确定终端设备在接收第一指示信息之前,存在第二上行数据待传输。本申请实施例的技术方案示例性的提供了网络设备确定终端设备在接收第一指示信息之前,存在第二上行数据待传输的方式。
结合上述第一方面,在一种可能的设计中,网络设备确定终端设备在接收第一指示信息之前存在第二上行数据待传输包括:网络设备接收来自终端设备的第三信息,第三信息用于指示终端设备将在传输第一上行数据后传输第二上行数据。网络设备根据第三信息,确定终端设备在接收第一指示信息之前存在第二上行数据待传输。本申请实施例的技术方案示例性地提供了网络设备确定终端设备在接收第一指示信息之前,存在第二上行数据待传输的方式。
结合上述第一方面,在一种可能的设计中,第一指示信息和第二指示信息携带在上行授权消息中。本申请实施例的技术方案提供了一种发送第一指示信息和第二指示信息的方式。
第二方面,提供了一种上行数据传输方法。执行该方法的通信装置(主体)可以为网络设备也可以为应用于网络设备中的模块,例如芯片。下面以执行主体为网络设备为例描述。该方法包括:网络设备接收来自终端设备的第四信息,第四信息用于指示第一周期。网络设备根据第一周期确定第一配置信息,并向终端设备发送第一配置信息。其中第一配置信息用于终端设备配置第二周期;第二周期为终端设备向网络设备发送第五信息的周期。第二周期小于等于终端设备向网络设备发送每帧上行数据的周期。第五信息用于指示终端设备待传输的上行数据的数据量。
基于本申请实施例的技术方案,可以使网络设备根据终端设备发送的第一周期,为终端设备配置第二周期,从而实现终端设备按照第二周期向网络设备发送第五信息,即使有的待传输上行数据按照regular BSR触发机制无法触发regular BSR,终端设备也可以通过周期性发送的第五信息,为这些待传输上行数据申请上行资源。
结合上述第二方面,在一种可能的设计中,第四信息携带在终端设备辅助信息中。 本申请实施例的技术方案提供了一种发送第四信息的方式。
第三方面,提供了一种上行数据传输方法。执行该方法的通信装置(主体)可以为终端设备也可以为应用于终端设备中的模块,例如芯片。下面以执行主体为终端设备为例描述。该方法包括:终端设备向网络设备发送第一信息和第二信息。第一信息用于指示终端设备待传输的第一上行数据的数据量;第二信息用于指示与第一上行数据对应的第一时长。若终端设备能够在第一时长内发送第一上行数据至网络设备,且终端设备在接收第一指示信息之前存在第二上行数据待传输,终端设备接收来自网络设备的第一指示信息和第二指示信息。第一指示信息用于指示第一上行资源的信息。第二指示信息用于指示以下的至少一项:终端设备在第一上行资源上优先发送第一上行数据;或者,终端设备提高第一上行数据对应的第一逻辑信道的优先比特率。
基于本申请实施例的技术方案,网络设备在收到终端设备发送的指示第一上行数据的数据量的第一信息,以及与第一上行数据对应的第一时长后,若终端设备在收到分配的第一上行资源期间有新的第二上行数据待传输,为了避免为终端设备分配的第一上行资源被终端设备过多地用于传输第二上行数据,导致出现第一上行资源不足以传输完第一上行数据的情况,网络设备可以通过第二指示信息指示终端设备在第一上行资源上优先发送第一上行数据,和/或,提高第一上行数据对应的第一逻辑信道的优先比特率,从而保证终端设备可以在第一上行资源上完整发送第一上行数据,避免出现第一上行数据传输超时,导致无法正确解码数据,影响用户体验的情况。
结合上述第三方面,在一种可能的设计中,在终端设备接收来自网络设备的第一指示信息和第二指示信息之前,第一优先级低于第二优先级;第一优先级为第一上行数据对应的第一逻辑信道的优先级,第二优先级为第二上行数据对应的第二逻辑信道的优先级。本申请实施例的技术方案可以应用于第一优先级低于第二优先级的场景中,从而解决若第一优先级低于第二优先级,可能会导致未传完的第一上行数据无法在配置的PDB内传完的问题。
结合上述第三方面,在一种可能的设计中,第一逻辑信道为前向预测编码帧对应的逻辑信道;第二逻辑信道为全帧压缩编码帧对应的逻辑信道。第一上行数据为前向预测编码帧,第二上行数据为全帧压缩编码帧。本申请实施例的技术方案可以应用于前向预测编码帧对应的逻辑信道配置的优先级,低于全帧压缩编码帧对应的逻辑信道配置的优先级的场景中,从而解决XR业务中,未传完的全帧压缩编码帧数据可能无法在配置的PDB内传完的问题。
结合上述第三方面,在一种可能的设计中,第二指示信息用于指示终端设备在第一上行资源上优先发送第一上行数据包括:第二指示信息用于指示终端设备将第一优先级调整为第三优先级,其中第三优先级高于第二优先级。
基于本申请实施例的技术方案,终端设备可以根据第二指示信息调整第一上行数据对应的逻辑信道原先的优先级,使调整后的第一上行数据对应的逻辑信道的优先级,高于第二上行数据对应的逻辑信道的优先级。因为终端设备会优先传输优先极高的逻辑信道上的上行数据,所以终端设备会在第一上行资源上优先发送第一上行数据。
结合上述第三方面,在一种可能的设计中,在第二指示信息用于指示终端设备提高第一上行数据对应的第一逻辑信道的优先比特率的情况下,第二指示信息还用于指 示终端设备降低第二上行数据对应的第二逻辑信道的优先比特率。基于本申请实施例的技术方案,可以提高第一逻辑信道的优先比特率,且降低第二逻辑信道的优先比特率,实现使第一上行资源更多地分配给第一上行数据,更少地分配给第二上行数据。
结合上述第三方面,在一种可能的设计中,第二指示信息用于指示终端设备在第一上行资源上优先发送第一上行数据包括:第二指示信息用于指示第一上行资源仅能用于传输第一逻辑信道对应的上行数据。其中第一上行数据对应第一逻辑信道,第二上行数据对应第二逻辑信道。基于本申请实施例的技术方案,终端设备可以根据第二指示信息,仅将第一上行资源分配给第一逻辑信道上的第一上行数据,不会将第一上行资源分配给第二逻辑信道上的第二上行数据,从而实现在第一上行资源上优先发送第一上行数据。
结合上述第三方面,在一种可能的设计中,在终端设备接收来自网络设备的第一指示信息和第二指示信息之前,该方法还包括:终端设备向网络设备发送上行数据的周期信息;周期信息用于网络设备确定终端设备在接收第一指示信息之前,存在第二上行数据待传输。本申请实施例的技术方案示例性地提供了网络设备确定终端设备在接收第一指示信息之前,存在第二上行数据待传输的方式。

具体实施方式
为了便于理解本申请实施例的技术方案,首先给出本申请涉及的相关技术名词的简要介绍如下。
1、终端设备申请上行资源的方式:
在通信系统中,当终端设备需要向网络侧(网络设备)发送上行数据时,终端设备需要通过上行资源来发送上行数据,若终端设备没有上行资源,则需要向网络设备申请上行资源。通常,终端设备可以通过以下三种方式向网络设备申请上行资源:
(1)向网络设备发送BSR。终端设备可以在介质访问控制(media access control,MAC)层的协议数据单元(protocol data unit,PDU)中插入一个BSR控制单元来通知网络设备:终端设备的某个或某几个逻辑信道组(logical channel group,LCG)中当前有多少数据需要发送,需要网络设备分配一些上行资源给终端设备。其中,一个LCG包括多个LCH,LCH用于MAC层的数据传输服务,MAC层可以将LCH映射到传输信道上,从而传输LCH上的待传输数据。
当网络设备收到终端设备发送的BSR后,会给终端设备发送UL grant,用来指示网络设备为终端设备分配的上行资源,其中包括上行资源的位置、调制与编码策略(molation and coding scheme,MCS)等上行资源的相关信息。
这种通过发送BSR申请上行资源的方式,可以让网络设备知道终端设备需要发送的数据量,从而可以针对性地分配上行资源。但是这里有个问题,因为BSR是被封装在MAC PDU里,通过物理上行共享信道(physical uplink shared channel,PUSCH)信道发送到网络设备的,所以终端设备发送BSR这个动作本身也是需要上行资源的,如果终端设备没有任何上行资源,也是没有办法发送BSR的,那么这个时候终端设备就需要下面这种方式向网络设备申请上行资源。
(2)向网络设备发送调度请求(scheduling request,SR)。当终端设备无法发送BSR申请上行资源的时候,可以通过发送SR的方式申请上行资源,SR可以在物理上行控制信道(physical uplink control channel,PUCCH)中传输,并不需要上行资源就可以发送给网络设备。但SR只是告诉网络设备有上行数据要发送,而没有告诉网络设备终端设备有多少上行数据要发,网络设备并不清楚该分配多少上行资源,因此后续终端设备可能仍然需要发送BSR来申请更多的(或者说额外的)上行资源。网络设备收到终端设备的SR后,分配多少上行资源是由网络设备厂家的算法决定的。一般来说,网络设备收到SR后,分配的上行资源至少能够满足BSR的发送。
但是,并不是所有的终端设备都能发出SR。如果某个终端设备既无法发送BSR,又不能发送SR,这个时候终端设备就需要发起竞争随机接入过程了。
(3)发起竞争随机接入。在这种方式中,终端设备将在随机接入过程中的第三条消息(message 3,MSG3)中插入一个BSR控制单元来向网络设备申请上行资源,竞争随机接入的具体流程可参考现有标准,在此不再赘述。
上述三种方式中,本申请实施例的方案主要涉及终端设备向网络设备发送BSR来申请上行资源的方式。
2、终端设备分配上行资源:
当网络设备为终端设备分配上行资源后,终端设备根据LCH的优先级来给LCH上待传输的上行数据分配上行资源,不同的LCH有不同的优先级,优先级高的LCH上的数据会优先通过上行资源去发送。LCH的优先级是由网络设备通过无线资源控制(radio resource control,RRC)信令配置下来的。
需要说明的是,在终端设备向网络设备发送BSR的方式中,终端设备基于LCG向网络设备发送BSR,但终端设备上报的BSR基于的LCG与网络设备分配的上行资源之间没有直接对应关系。终端设备基于某个或某几个LCG发送BSR后,网络设备根据BSR分配给终端设备的上行资源,并不一定被终端设备分配给这某个或某几个LCG中的LCH上的上行数据,而是根据LCH的优先级进行分配。换言之,某一LCH上的上行数据能否被终端设备分配上行资源,与终端设备是否基于该LCH属于的LCG发送BSR之间没有对应关系。
但是,如果终端设备仅根据LCH的优先级高低为LCH上的数据分配上行资源,可能会导致优先级低的LCH上的数据迟迟发不出去。为了解决这个问题,标准中引入了优先比特率(prioritised bit rate,PBR)的概念,避免高优先级的LCH始终占据网络设备给终端设备分配的无线资源。PBR对应的数据可以理解为某一LCH上的待传输的数据中,单位时间内优先传输的数据。终端设备在为各个LCH上的待传输数据分配上行资源时,会优先为各个LCH的分别的PBR所对应的数据分配上行资源,再为各个LCH上除分别的PBR对应的数据以外的剩余的数据分配上行资源,从而为每个LCH提供了最小数据传输速率保证。LCH的PBR是由网络设备通过RRC信令配置下来的。
终端设备根据LCH的PBR分配上行资源的具体过程,可以结合如图1所示的示例,进一步展开说明。如图1所示,终端设备总共有3个LCH:LCH1、LCH2和LCH3,分别对应PBR1、PBR2和PBR3,这三个LCH的优先级高低顺序为LCH1>LCH2>LCH3。当这3个LCH上都有待传输的上行数据时,终端设备会首先给LCH1中PBR1对应的部分数据(数据1)分配上行资源,其次再给LCH2中PBR2对应的部分数据(数据2)分配上行资源,再次给LCH3中PBR3对应的部分数据(数据3)分配上行资源。终端设备为LCH3中PBR3对应的部分数据分配好上行资源之后,若仍有剩余的上行资源,再把剩余的上行资源分配给优先级最高的LCH1中,除去PBR1对应的部分数据之外的数据(数据4)。另外,虽然图1没有示出,如果仍有剩余的上行资源,终端设备会再把剩余的上行资源分配给优先级次高的LCH2中,除去PBR2对应的部分数据之外的数据。
3、XR业务:
XR业务中的视频帧分为I帧和P帧。其中,I帧是一个全帧压缩编码帧,包含整帧的图像信息。P帧为前向预测编码帧,表示的是这一帧与前一帧的差值,即解码P帧需要参考前一帧的相关信息。如图2所示,编码器将组成视频的多张图像进行编码后产生一段一段的GOP,每个GOP由一个I帧和数个P帧组成。
XR业务呈周期性,XR业务的帧数据是周期性生成的。例如XR业务的周期为60fps, 即一秒钟产生60帧画面帧,平均帧生成周期为16.67毫秒(ms)。
通常,终端设备运行XR业务时,若终端设备需要传输帧数据,终端设备需要在配置的PDB(上行数据帧产生的时间到成功发给接收端的时间差)内,向网络设备传输完一帧的数据,从而使网络设备可以及时地把收到的数据帧发给云端,让云端正确解码。如果在PDB内终端设备没有传输完这一帧的数据,终端设备会丢弃这一帧剩余的待传数据,导致云端无法接收到完整的帧数据。一般来说,PDB为30毫秒(ms)。可选的,还可以为10ms、15ms或60ms。
4、技术方案一:
从上文可知,XR业务分I帧和P帧。但因为I帧包含整帧的信息,P帧要参考前一帧的信息才能进行解码,所以可以认为I帧比P帧更重要。因此,有一种方案,当网络负载较重时,可以通过不同的服务质量流(quality of service,QoS flow)传输I帧和P帧,不同的QoS flow对应不同优先级的LCH,用于传输I帧的QoS flow对应的LCH的优先级高于用于传输P帧的QoS flow对应的LCH,从而实现优先传输更重要的I帧,来保证用户体验,并能增加网络容量。
但这种方案可能会导致出现以下问题:终端设备传输P帧数据时,若因配置的上行资源不足而有未传完的P帧数据,终端设备会发送BSR给网络设备来请求额外的上行资源。但在终端设备收到相应的UL grant之前,如果有I帧数据到达(指终端设备新产生的I帧数据),因为I帧数据对应的LCH的优先级高于P帧数据对应的LCH的优先级,终端设备在收到UL grant之后,会将UL grant指示的上行资源优先分配给新到达的I帧数据,则可能导致未传完的P帧数据无法在配置的PDB内传完。以下结合附图,对该方案可能引起的相关问题进行展示。
示例性地,图3为通过时间线展示的相关问题的示意图。如图3所示,终端设备有一个上行P帧的数据需要传输给网络设备,但因为网络设备之前分配的上行资源不足以传输完该P帧的数据,此时终端设备发送该P帧的部分数据和BSR给网络设备。网络设备接收到这部分P帧数据和BSR后,向终端设备发送UL grant。而在网络设备发送UL grant前,一个新的I帧也在终端设备侧产生,当终端设备收到UL grant后,因为I帧数据对应的LCH的优先级高于P帧数据对应的LCH的优先级,所以会优先把UL grant指示的上行资源分配给新产生的I帧数据,再分配给剩余的P帧数据。如果UL grant指示的上行资源还不足以传完剩余的P帧数据的话,则可能会导致发送这剩余P帧数据的时间超过配置的PDB的要求,即超时。
示例性地,图4为通过MAC层复用所展示的相关问题示意图。如图4所示,终端设备共有2个LCH:LCH1和LCH2,分别对应PBR1和PBR2,LCH1和LCH2分别用于传输I帧数据和P帧数据,LCH1的优先级高于LCH2的优先级。网络设备为终端设备分配UL grant相应的上行资源后,由于LCH1的优先级高于LCH2,所以终端设备会优先分配上行资源给LCH1上的数据。即新到的I帧数据,首先分给LCH1中PBR1对应的数据(数据1),再分配资源给LCH2中PBR2对应的数据(数据2),若还有剩余上行资源,则分给LCH1中除去PBR1对应的数据之外的剩余I帧数据(数据3),从而导致LCH2中除去PBR2对应的数据之外的剩余P帧数据(数据4)无法在PDB内发出。而超过PDB后终端设备会丢弃还未传输的剩余的P帧数据,这会导 致云端无法接收到完整画面帧而无法正确解码,并且浪费了终端设备之前已成功传输的部分P帧数据,因此终端设备侧浪费了功耗,而网络侧浪费了资源。
5、技术方案二:
根据上文可知,终端设备可以通过发送BSR申请上行资源。在标准中,BSR中的正常BSR(regular BSR)的触发机制如下:
1.终端设备的上行buffer中没有数据且有新的数据到达:当所有LCG中的所有LCH都没有需要发送的上行数据时,如果此时任意一个LCG中的LCH有新的数据产生,则终端设备会触发regular BSR,向网络设备发送BSR。
2.高优先级的数据到达时:如果终端设备已经发出了一个BSR,并且正在等待UL grant,在等待期间,如果相比于之前发出的BSR所基于的LCG中有上行数据的LCH,有更高优先级的LCH有数据要发送,则终端设备会触发regular BSR,向网络设备发送BSR。
但是,上述两种触发机制可能会导致出现以下问题:如果终端设备上报P帧数据和BSR后,在等待UL grant时,下一个P帧的数据已经产生,按照上述的regular BSR触发机制,终端设备无法再为这个新的P帧数据触发regular BSR。示例性地,如图5所示,终端设备当前的上行资源无法传完第一个P帧的所有数据包,则发送数据包1-3和BSR给网络设备,该通过BSR来请求用于传输数据包4的额外的上行资源。而在等待UL grant的期间,终端设备产生了第二个P帧。终端设备收到UL grant后,可以通过UL grant指示的上行资源传输第一个P帧的数据包4,但在第二个P帧与第一个P帧对应同一LCH,或者第二个P帧对应的LCH的优先级不高于第一个P帧对应的LCH的优先级的情况下,在这之前第二个P帧已经生成的数据包(图5中虚线部分包括的数据包)则因为不符合两种触发regular BSR的机制(生成这些数据包时,LCH中还存在第一个P帧的数据包4,不符合第1条机制;第二个P帧对应的LCH的优先级不高于第一个P帧对应的LCH的优先级,不符合第2条机制),使得终端设备无法为第二个P帧已经生成的数据包向网络设备发送BSR,从而导致无法发出第二个P帧已经生成的数据包。
综上,按照上述的技术方案(技术方案一和技术方案二),终端设备在运行XR业务时,可能会出现某帧的数据无法在配置的PDB内传输完成,甚至无法传输部分帧数据的情况,进而导致云端无法接收到完整的帧数据以及无法正确解码帧数据,严重影响用户体验。并且浪费了终端设备之前已成功传输的部分帧数据,导致终端设备侧浪费了功耗,而网络侧浪费了资源。因此,如何保障终端设备可以完整传输帧数据,是亟待解决的问题。

下面将结合图1至图8,以图6所示的网络设备20与任一终端设备30进行交互为例,对本申请实施例提供的上行数据传输方法进行展开说明。
示例性地,图9为本申请实施例提供的一种上行数据传输方法。如图9所示,该上行数据传输方法包括S901-S904:
S901、终端设备向网络设备发送第一信息。相对应的,网络设备接收来自终端设备的第一信息,第一信息用于指示终端设备待传输的第一上行数据的数据量。
S902、网络设备根据第一信息确定第一上行资源。
S903、终端设备向网络设备发送第二信息。相对应的,网络设备接收来自终端设备的第二信息,第二信息用于指示与第一上行数据对应的第一时长。
S904、若网络设备根据第一上行数据的数据量和第一时长,确定终端设备能够在第一时长内发送第一上行数据至网络设备,且确定终端设备在接收第一指示信息之前 存在第二上行数据待传输,网络设备向终端设备发送第一指示信息和第二指示信息。相对应的,终端设备接收来自网络设备的第一指示信息和第二指示信息。其中,第一指示信息用于指示第一上行资源的信息。第二指示信息用于指示以下的至少一项:终端设备在第一上行资源上优先发送第一上行数据;或者,终端设备提高第一上行数据对应的第一逻辑信道的优先比特率。
对于S901,本申请实施例中,终端设备有待传输的第一上行数据,且终端设备没有足够的上行资源来传输第一上行数据时,终端设备向网络设备发送第一信息来为第一上行数据申请上行资源。网络设备接收到第一信息后,则可以根据第一信息确定为终端设备分配上行资源。其中,第一信息用于指示待传输的第一上行数据的数据量,以使网络设备可以根据第一上行数据的数据量,针对性地为第一上行数据分配上行资源。
本申请实施例中,终端设备有待传输的第一上行数据,且终端设备没有足够的上行资源来传输第一上行数据的情况,具体为:终端设备当前的待传输上行数据包括第一上行数据和其他上行数据,终端设备当前的上行资源若用于传输其他上行数据,剩余的上行资源不足以传输第一上行数据。该情况中,终端设备可以向网络设备发送第一信息和其他上行数据,以使网络设备根据第一信息为第一上行数据分配额外的上行资源。
示例性的,本申请实施例中,第一信息可以为BSR。
对于S902,本申请实施例中,网络设备可以根据第一信息指示的第一上行数据的数据量,确定传输第一上行数据需要多少上行资源,从而确定用于传输第一上行数据的第一上行资源。
对于S903,终端设备可以向网络设备发送指示第一时长的第二信息。其中,第一时长可以理解为终端设备为传输第一上行数据预留的时长,若终端设备可以在第一时长内成功传输第一上行数据至网络设备,则意味着第一上行数据没有超时,终端设备无需丢弃剩余的待传数据。可选的,第一时长可以为配置的PDB时长减去终端设备从产生第一上行数据到准备向网络设备发送第一上行数据的时长。换言之,第一时长可以为配置的PDB减去终端设备用于准备向网络设备发送第一上行数据的时长后,剩余的PDB时长。
可选的,本申请实施例中,终端设备可以同时发送第一信息和第二信息。换言之,S901和S903可以同时执行,而S902可以在S901和S903之后执行。第一信息可以与第二信息携带在同一消息或信令中,也可以携带在不同消息或信令中,本申请实施例对此不作限制。
对于S904,网络设备在接收到第一信息和第二信息后,需要执行以下两次判断:
第一次判断:根据第一上行数据的数据量和第一时长,判断若为终端设备分配第一上行资源,终端设备能否在第一时长内发送第一上行数据至网络设备。具体地,网络设备可以根据第一上行数据的数据量、第一时长以及预配置的算法,计算出终端设备能否在第一时长内发送第一上行数据至网络设备。
对于第一次判断,本申请实施例中,网络设备进行第一次判断判断的具体实现与网络设备之后可能向终端设备发送的第二指示信息相关,具体在下文进行展开介绍。
第二次判断:判断若向终端设备发送第一指示信息,终端设备是否在接收第一指示信息之前存在第二上行数据待传输。其中,第二上行数据为与第一上行数据不同的数据。第一指示信息用于指示第一上行资源的信息,以使终端设备可以根据第一指示信息确定第一上行资源。
可选的,第一指示信息可以包括第一上行资源的时频域位置和MCS等相关信息。示例性的,第一指示信息可以为UL grant。
对于第二次判断,一种可能的实现方式中,网络设备可以通过以下步骤判断终端设备是否在接收第一指示信息之前存在第二上行数据待传输。
网络设备获取终端设备向网络设备发送的上行数据的周期信息,并根据周期信息,判断终端设备在接收第一指示信息之前,是否存在第二上行数据待传输。
其中,上行数据的周期信息包括上行数据的格式信息,以及时间周期信息等信息。示例性的,终端设备运行XR业务时,按照GOP,即一个I帧后跟数个P帧的顺序,向网络设备发送每一帧数据。则上行数据的周期信息可以包括GOP的格式信息,例如为一个GOP中,第一个I帧后包括3个P帧,以及平均帧生成周期(产生每帧数据的周期)信息,例如为16.67ms。网络设备获取上行数据的周期信息后,可以根据周期信息,确定终端设备在接收第一指示信息之前,是否会产生(或到达)新的上行数据。进一步地,还可以确定新的上行数据的数据类型等相关信息,从而确定终端设备在接收第一指示信息之前,是否存在第二上行数据待传输。
可选的,上行数据的周期信息可以是预配置在网络设备中的,也可以是终端设备发送(例如通过RRC信令发送)给网络设备的。
对于第二次判断,在另一种可能的实现方式中,网络设备可以通过以下步骤,判断终端设备在接收第一指示信息之前是否存在第二上行数据待传输。
终端设备向网络设备发送第三信息,相对应的,网络设备接收来自终端设备的第三信息,第三信息用于指示终端设备将在传输第一上行数据后传输第二上行数据。网络设备根据第三信息,确定终端设备在接收第一指示信息之前存在第二上行数据待传输。在该实现方式中,网络设备可以直接根据来自终端设备的第三信息,确定终端设备在接收第一指示信息之前存在第二上行数据待传输。可选的,第三信息可以指示终端设备在第一上行数据之后将传输的上行数据的类型,例如指示下一帧为I帧。
可选的,终端设备可以通过MAC信令向网络设备发送第三信息。
若上述两次判断的结果均为“是”,即网络设备根据第一上行数据的数据量和第一时长,确定终端设备能够在第一时长内发送第一上行数据至网络设备,且确定终端设备在接收第一指示信息之前存在第二上行数据待传输,则网络设备执行之后的步骤:向终端设备发送第一指示信息和第二指示信息,否则不执行。其中,第二指示信息指示以下的至少一项:终端设备在第一上行资源上优先发送第一上行数据;或者,终端设备提高第一上行数据对应的第一逻辑信道的优先比特率。
可选的,若网络设备执行的两次判断中存在至少一次的判断结果为“否”,网络设备依然可以向终端设备发送第一指示信息来指示第一上行资源,但不发送第二指示信息。
需要说明的是,上述两次判断的名称“第一次判断”和“第二次判断”仅为叙述清楚, 本申请实施例并不限制网络设备执行第一次判断和第二次判断的时序顺序。
可选的,本申请实施例中,第一指示信息可以与第二指示信息携带在同一消息或信令中。例如,第一指示信息可以与第二指示信息携带在同一UL grant中。或者,第一指示信息可以与第二指示信息携带在不同消息或信令中。本申请实施例对此不作限制。
需要说明的是,本申请实施例中,第二指示信息指示终端设备执行对应步骤的作用,仅在终端设备接收到该第二指示信息的当次生效,终端设备不会根据某一第二指示信息,连续地执行对应的步骤。
本申请实施例中,终端设备在第一上行资源上优先发送第一上行数据,包括终端设备优先将第一上行资源分配给第一上行数据,而不包括优先将第一上行资源分配给第二上行数据。
可选的,本申请实施例中,网络设备向终端设备发送第一指示信息和第二指示信息的技术方案,可以应用于第一优先级低于第二优先级的场景。其中,第一优先级为第一上行数据对应的第一逻辑信道的优先级,第二优先级为第二上行数据对应的第二逻辑信道的优先级。参考上文对技术方案一的介绍可知,若第一优先级低于第二优先级且应用技术方案一,可能会导致未传完的第一上行数据无法在配置的PDB内传完的问题。而本申请实施例中,网络设备可以通过向终端设备发送第二指示信息,指示终端设备在第一上行资源上优先发送第一上行数据,和/或,指示终端设备提高第一上行数据对应的第一逻辑信道的优先比特率,从而保证终端设备可以在第一上行资源上传输第一上行数据,从而保证在配置的PDB内传输完第一上行数据,其具体实现在下文进行展开介绍。
进一步的,第一优先级低于第二优先级的场景具体可以为:网络设备为第一逻辑信道配置的优先级(第一优先级)低于网络设备为第二逻辑信道配置的优先级(第二优先级),第一逻辑信道为前向预测编码帧(I帧)对应的逻辑信道,第二逻辑信道为全帧压缩编码帧(P帧)对应的逻辑信道。换言之,在该场景中,在网络设备向终端设备发送第一指示信息和第二指示信息之前,网络设备若确定第一上行数据为P帧,第二上行数据为I帧,则可以确定第一上行数据对应的逻辑信道的优先级,低于第二上行数据对应的逻辑信道的优先级,即第一优先级低于第二优先级。其中,网络设备确定第一上行数据为P帧和第二上行数据为I帧的方式,可以参考上文介绍的网络设备确定终端设备在接收第一指示信息之前,是否存在第二上行数据待传输的方式。
另外,本申请实施例并不限定仅能应用于第一优先级低于第二优先级的场景,在第一优先级等于第二优先级,或者第一优先级高于第二优先级的场景中,本申请实施例的技术方案依然能够应用。
以下展开介绍第二指示信息。对于第二指示信息用于指示终端设备在第一上行资源上优先发送第一上行数据的情况,在一种可能的实现方式中,第二指示信息用于指示终端设备将第一优先级调整为第三优先级,其中,第三优先级高于第二优先级。
在该实现方式中,网络设备执行第一次判断的具体实现可以为:在终端设备已经调整第一上行数据对应的第一逻辑信道的原先的优先级,且调整后第一逻辑信道的优先级高于第二上行数据对应的第二逻辑信道的优先级的前提下,网络设备根据第一上 行数据的数据量以及第一时长,确定终端设备能否在第一时长内传输完成第一上行数据至网络设备。若网络设备确定调整优先级后的终端设备能够在第一时长内传输完成第一上行数据至网络设备,则第一次判断的结果为是。
该实现方式中,网络设备向终端设备发送第二指示信息后,终端设备根据第二指示信息,调整第一上行数据对应的第一逻辑信道原先的优先级(第一优先级),使调整后第一逻辑信道的优先级(第三优先级)高于第二上行数据对应的第二逻辑信道的优先级(第二优先级)。因为终端设备会优先传输优先极高的逻辑信道上的上行数据,所以终端设备会在第一上行资源上优先发送第一上行数据,并且,因为网络设备在之前确定若为终端设备分配第一上行资源,终端设备可以在第一时长内发送第一上行数据至网络设备,所以可以保证终端设备可以通过第一上行资源,在规定的时长内传输完第一上行数据,不会出现因为超时导致终端设备丢弃剩余的待传输的数据的情况。
以下结合附图,示例性地对该实现方式进行解释说明。如图10所示,终端设备总共有2个LCH:LCH1和LCH2,分别对应PBR1和PBR2,LCH1和LCH2分别用于传输I帧数据和P帧数据,网络设备配置LCH1的优先级高于LCH2的优先级。假设在LCH2中存在的待传输的P帧数据为第一上行数据,且当前的上行资源不足以传输第一上行数据,终端设备为第一上行数据向网络设备发送BSR,以及指示剩余PDB(第一时长)的第二信息后,在等待对应的UL grant期间产生了一个新的I帧(第二上行数据),即LCH1上的上行数据。网络设备根据该BSR以及第二信息,确定终端设备能够在剩余PDB内发送第一上行数据至网络设备,且终端设备在接收UL grant之前产生了一个I帧。因此,网络设备向终端设备发送UL grant以及指示终端设备将LCH2的优先级调高至高于LCH1的优先级的第二指示信息。终端设备收到UL grant以及第二指示信息后,确定UL grant指示的上行资源,并调高LCH2的优先级至高于LCH1的优先级。调整优先级后,终端设备在分配UL grant指示的上行资源时,先为LCH2上PBR2对应的第一上行数据分配上行资源(数据2),再为LCH1上PBR1对应的上行数据分配上行资源(数据1),然后为LCH2上剩余的第一上行数据分配上行资源(数据4),实现优先在第一上行资源上发送第一上行数据,不会出现超时的情况。
对于第二指示信息用于指示终端设备在第一上行资源上优先发送第一上行数据的情况,在另一种可能的实现方式中,第二指示信息用于指示第一上行资源仅能用于传输第一逻辑信道对应的上行数据。其中第一上行数据对应第一逻辑信道,第二上行数据对应第二逻辑信道。
在该实现方式中,网络设备执行第一次判断的具体实现可以为:网络设备根据第一上行数据的数据量以及第一时长,确定若第一上行资源仅用于传输第一上行数据,终端设备能否在第一时长内传输完成第一上行数据至网络设备。若网络设备确定终端设备能够在第一时长内传输完成第一上行数据至网络设备,则第一次判断的结果为是。
该实现方式中,网络设备向终端设备发送第二指示信息后,终端设备根据第二指示信息,仅将第一上行资源分配给第一逻辑信道上的第一上行数据,不会将第一上行资源分配给第二逻辑信道上的第二上行数据,从而实现在第一上行资源上优先发送第一上行数据。并且,因为网络设备在之前确定若为终端设备分配第一上行资源,终端设备可以在第一时长内发送第一上行数据至网络设备,所以可以保证终端设备可以通 过第一上行资源,在规定的时长内传输完第一上行数据,不会出现因为超时导致终端设备丢弃剩余的待传输的数据的情况。
以下结合附图,示例性地对该实现方式进行解释说明。如图11所示,终端设备总共有2个LCH:LCH1和LCH2,分别对应PBR1和PBR2,LCH1和LCH2分别用于传输I帧数据和P帧数据,网络设备配置LCH1的优先级高于LCH2的优先级。假设在LCH2中存在的待传输的P帧数据为第一上行数据,且当前的上行资源不足以传输第一上行数据,终端设备为第一上行数据向网络设备发送BSR,以及指示剩余PDB(第一时长)的第二信息后,在等待对应的UL grant期间产生了一个新的I帧(第二上行数据),即LCH1上的上行数据。网络设备根据该BSR以及第二信息,确定终端设备能够在剩余PDB内发送第一上行数据至网络设备,且终端设备在接收UL grant之前产生了一个I帧。因此,网络设备向终端设备发送UL grant以及指示终端设备UL grant对应的第一上行资源仅能用于传输LCH2上的上行数据的第二指示信息。终端设备收到UL grant以及第二指示信息后,确定UL grant指示的上行资源,并在分配UL grant指示的上行资源时,先为LCH2上PBR2对应的第一上行数据分配上行资源,然后为LCH2上剩余的第一上行数据分配上行资源,即仅为LCH2上的第一上行数据分配上行资源,不根据优先级为LCH1上的第一上行数据分配上行资源,实现优先在第一上行资源上发送第一上行数据,不会出现超时的情况。
第二指示信息还可以用于指示终端设备提高第一上行数据对应的第一逻辑信道的优先比特率,以使终端设备多传输第一上行数据。
该实现方式中,网络设备执行第一次判断的具体实现可以为:网络设备根据第一上行数据的数据量以及第一时长,确定若终端设备调整第一逻辑信道的优先比特率,终端设备能否在第一时长内传输完成第一上行数据至网络设备。若网络设备确定调整优先比特率后终端设备能够在第一时长内传输完成第一上行数据至网络设备,则第一次判断的结果为是。
该实现方式中,网络设备需要根据终端设备的第一上行数据的数据量和第一时长,计算可以使第一上行数据在第一时长内传输完成的优先比特率。然后,网络设备将计算出的优先比特率携带在第二指示信息中发送给终端设备,并通过第二指示信息指示终端设备将第一逻辑信道的优先比特率提高至第二指示信息携带的优先比特率。
可选的,该情况中,第二指示信息还可以用于指示终端设备降低第二上行数据对应的第二逻辑信道的优先比特率。可选的,网络设备可以在第二指示信息中携带网络设备确定的降低后的第二逻辑信道的优先比特率,或者,第二指示信息可以仅指示降低第二逻辑信道的优先比特率而不指示具体数值。基于本方案,可以提高第一逻辑信道的优先比特率且降低第二逻辑信道的优先比特率,实现使第一上行资源更多地分配给第一上行数据,更少地分配给第二上行数据。
以下结合附图,示例性地对该情况下的第二指示信息进行解释说明。如图12所示,终端设备总共有2个LCH:LCH1和LCH2,分别对应PBR1和PBR2,PBR1大于PBR2。LCH1和LCH2分别用于传输I帧数据和P帧数据,网络设备配置LCH1的优先级高于LCH2的优先级。假设在LCH2中存在的待传输的P帧数据为第一上行数据,且当前的上行资源不足以传输第一上行数据,终端设备为第一上行数据向网络设备发送BSR, 以及指示剩余PDB(第一时长)的第二信息后,在等待对应的UL grant期间产生了一个新的I帧(第二上行数据),即LCH1上的上行数据。网络设备根据该BSR以及第二信息,确定终端设备能够在剩余PDB内发送第一上行数据至网络设备,且终端设备在接收UL grant之前产生了一个I帧。因此,网络设备计算出PBR2调高后的取值:PBR2.1,以及PBR1降低后的取值:PBR1.1,并向终端设备发送UL grant以及指示终端设备调高PBR2至PBR2.1,降低PBR1至PBR1.1的第二指示信息。终端设备收到UL grant以及第二指示信息后,确定UL grant指示的上行资源,并将LCH2对应的PBR2调高至PBR2.1,将PBR1降低至PBR1.1。在分配UL grant指示的上行资源时,终端设备先为LCH1上PBR1.1对应的上行数据(数据1)分配上行资源,再为LCH2上PBR2.1对应的第一上行数据(数据2)分配上行资源。因为调整后的PBR2.1足够高,所以LCH2上的第一上行数据可以全部通过第一上行资源发送,不会出现超时的情况。
上文介绍的第二指示信息的不同实现方式,可以独立应用,也可以结合应用,本申请实施例对此不做限制。换言之,第二指示信息指示以下的至少一项:终端设备在第一上行资源上优先发送第一上行数据;或者,终端设备提高第一上行数据对应的第一逻辑信道的优先比特率,可以包括以下多种情况:
第二指示信息指示终端设备在第一上行资源上优先发送第一上行数据,该情况包括指示终端设备将第一优先级调整为第三优先级,和/或,指示第一上行资源仅能用于传输第一逻辑信道对应的上行数据。
第二指示信息指示终端设备提高第一上行数据对应的第一逻辑信道的优先比特率。可选的,该情况中第二指示信息还可以指示终端设备降低第二上行数据对应的第二逻辑信道的优先比特率。
第二指示信息指示终端设备在第一上行资源上优先发送第一上行数据,且指示终端设备提高第一上行数据对应的第一逻辑信道的优先比特率。
基于本申请实施例的技术方案,网络设备在收到终端设备发送的指示第一上行数据的数据量的第一信息,以及与第一上行数据对应的第一时长后,若确定终端设备在收到分配的第一上行资源期间有新的第二上行数据待传输,为了避免为终端设备分配的第一上行资源被终端设备过多地用于传输第二上行数据,导致出现第一上行资源不足以传输完第一上行数据的情况,网络设备可以通过第二指示信息指示终端设备在第一上行资源上优先发送第一上行数据,和/或,提高第一上行数据对应的第一逻辑信道的优先比特率,从而保证终端设备可以在第一上行资源上完整发送第一上行数据,避免出现第一上行数据传输超时,导致无法正确解码数据,影响用户体验的情况。
其中,上述步骤S901至S904中网络设备的动作可以由图7所示的终端设备30中的处理器301调用存储器302中存储的应用程序代码以指令终端设备执行。上述步骤S901至S904中网络设备的动作可以由图7所示的网络设备20中的处理器201调用存储器202中存储的应用程序代码以指令网络设备执行。本实施例对此不作任何限制。
示例性地,图13为本申请实施例提供的另一种上行数据传输方法。如图13所示,该上行数据传输方法包括S1301-S1302:
S1301、终端设备向网络设备发送第四信息。相对应的,网络设备接收来自终端设备的第四信息,第四信息用于指示第一周期。
S1302、网络设备根据第一周期确定第一配置信息,并向终端设备发送第一配置信息。其中,第一配置信息用于终端设备配置第二周期。第二周期为终端设备向网络设备发送第五信息的周期。第二周期小于等于终端设备向网络设备发送每帧上行数据的周期。第五信息用于指示终端设备待传输的上行数据的数据量。
对于S1301,终端设备可以根据预配置的算法,确定出一个自身期望的向网络设备发送第五信息的周期,即第一周期。其中,第五信息用于指示终端设备待传输的上行数据的数据量,终端设备可以通过第五信息,为待传输的上行数据向网络设备申请上行资源。换言之,第一周期为终端设备期望的,向网络设备申请上行资源的周期。
终端设备确定出第一周期后,将第一周期携带在第四信息中发送给网络设备,以使网络设备获知终端设备期望的向网络设备发送第五信息的周期。
可选的,第四信息可以携带在终端设备辅助信息(UE assistance information)中。
对于S1302,网络设备在收到来自终端设备的第四信息后,可以根据第一周期,确定第二周期,并通过第一配置信息为终端设备配置第二周期。而第二周期为终端设备向网络设备发送第五信息的周期。换言之,终端设备配置第二周期后,可以按照第二周期,周期性地向网络设备发送第五信息,从而周期性地为终端设备待传输的上行数据申请上行资源。
示例性的,第五信息可以为BSR,也可以称为周期BSR(periodic BSR)。该情况下,第一周期可以称为优先的BSR周期(preferred periodic BSR-Timer)。
基于本申请实施例的技术方案,可以使网络设备根据终端设备发送的第一周期,为终端设备配置第二周期,从而实现终端设备按照第二周期向网络设备发送第五信息。即使有的待传输上行数据按照上述的regular BSR触发机制无法触发regular BSR,终端设备也可以通过周期性发送的第五信息,为这些待传输上行数据申请上行资源。
可选的,本申请实施例中,网络设备可以根据预配置的算法以及第一周期确定第二周期,确定的第二周期可以与第一周期相同,也可以与第一周期不同,本申请实施例对此不做限制。但是,为了使终端设备新产生或到达的每帧数据都能在PDB内传输成功,网络设备确定出的第二周期需要小于等于帧周期(frame period),其中帧周期为平均帧生成周期。
以下结合附图,对S1301-S1302的方案进行示例性的说明。如图14所示,假设网络设备通过第一配置信息为终端设备配置第二周期。终端设备当前的上行资源无法传完第一个P帧的所有数据包,则发送数据包1-3和BSR给网络设备,来请求用于传输数据包4的额外的上行资源。而在等待UL grant的期间,终端设备产生了第二个P帧。终端设备收到UL grant后,可以通过UL grant指示的上行资源传输第一个P帧的数据包4,但在第二个P帧与第一个P帧对应同一LCH,或者第二个P帧对应的LCH的优先级不高于第一个P帧对应的LCH的优先级的情况下,在这之前第二个P帧已经生成的数据包(图14中的虚线部分包括的数据包)因为不符合上述的两种触发regular BSR的机制,终端设备无法为第二个P帧已经生成的数据包向网络设备发送regular BSR,但是终端设备可以根据第二周期发送periodic BSR(第五信息)。而终端设备在发送此periodic BSR时,待传输的上行数据包括第二个P帧的所有数据包,因此终端设备发送的periodic BSR用于指示第二个P帧的所有数据包的数据量,以使网络设备为第 二个P帧分配上行资源。
其中,上述步骤S1301至S1302中网络设备的动作可以由图7所示的终端设备30中的处理器301调用存储器302中存储的应用程序代码以指令终端设备执行。上述步骤S1301至S1302中网络设备的动作可以由图7所示的网络设备20中的处理器201调用存储器202中存储的应用程序代码以指令网络设备执行。本实施例对此不作任何限制。
可以理解的是,以上各个实施例中,由终端设备实现的方法和/或步骤,也可以由可用于终端设备的部件(例如芯片或者电路)实现;由网络设备实现的方法和/或步骤,也可以由可用于网络设备的部件(例如芯片或者电路)实现。
上述主要从各个设备之间交互的角度对本申请实施例提供的方案进行了介绍。相应的,本申请实施例还提供了通信装置(主体),该通信装置用于实现上述各种方法。该通信装置可以为上述方法实施例中的终端设备,或者包含上述终端设备的装置,或者为可用于终端设备的部件;或者,该通信装置可以为上述方法实施例中的网络设备,或者包含上述网络设备的装置,或者为可用于网络设备的部件。可以理解的是,该通信装置为了实现上述功能,其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到,结合本文中所公开的实施例描述的各示例的单元及算法步骤,本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行,取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能,但是这种实现不应认为超出本申请的范围。
本申请实施例可以根据上述方法实施例中对通信装置进行功能模块的划分,例如,可以对应各个功能划分各个功能模块,也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现,也可以采用软件功能模块的形式实现。需要说明的是,本申请实施例中对模块的划分是示意性的,仅仅为一种逻辑功能划分,实际实现时可以有另外的划分方式。
