- a measurement as defined by M6 in the communication protocol TS 37.320 5.2.1.1 and 5.4.1.1 is a measurement for the PDB. Taking NR as an example, the measurement quantity and measurement method of M6 are introduced.

- Uplink Packet Data Convergence Protocol (PDCP) delay refers to the PDCP queuing delay of each DRB measured by the UE side, that is, from the PDCP packet to the service access point (Service Access Point, SAP) The time interval between the upper layer and the acquisition of the uplink grant (UL grant) for data packet transmission;
- PDCP Uplink Packet Data Convergence Protocol
- Air interface delay which refers to the time interval from the transmission time indicated by the scheduling grant (grant) to the successful reception of the transmission data block;
- Radio Link Control (RLC) delay refers to the RLC layer from receiving the RLC Protocol Data Unit (Protocol Data Unit) containing the first RLC Service Data Unit (SDU) , PDU) to the time interval from submitting the RLC SDU to the PDCP layer;
- RLC Radio Link Control
- the delay on the F1-U interface refers to the time interval for delivering data packets from the Distributed Unit (DU) to the Centralized Unit (CU);
- D2.4 PDCP reordering delay, which refers to the time interval between PDCP layer receiving PDCP PDU and delivering PDCP SDU to upper layer SAP;
- the uplink data packet delay is defined as D1+D2.1+D2.2+D2.3+D2.4, where D1 is reported by the UE to the RAN.

- the transmission needs to be adjusted. Judging whether it meets the needs of survival time is based on whether it exceeds the PDB.
- the UE does not know the PDB on the base station side, and the base station obtains the average PDB of the packet according to the UE report, and the statistical duration of the average PDB is basically the average PDB value of all packets within the time interval between two measurement reports.
- the minimum time interval between two measurement reports is 160ms. This is far greater than the TSC service requirements (the minimum TSC service period is 0.5ms, and the survival time may be several multiples of the period, such as the order of 10ms). Therefore, when the second average PDB has not been reported, it may be considered that the peer uses the last PDB value, so that there is no problem, but the actual survival time has expired. Therefore, an accurate PDB determination method needs to be considered to ensure the transmission performance.
- the present application proposes a solution for determining the PDB, which can accurately determine the PDB.

为便于更好的理解本申请实施例,对本申请相关的存活时间(survival time)进行说明。
对一个应用或业务来说,当survival time以业务周期表征时,若survival time=周期时,当前一个包传输失败后,后一个包一定要正确传输。否则,通信业务传输出错。
或者说,对一个应用或业务来说,当survival time以连续传输错误的包表征时,若survival time=X个连续传输错误的包,当X包连续传输错误则通信业务传输出错。所以,当有连续X-1个包传输失败后,后一个包一定要正确传输。
一个突发(burst)对应一个消息(message),一个突发(burst)包括一个或多个包(packet)。
为便于更好的理解本申请实施例,对本申请相关的PDB进行说明。
当前(Immediate)最小化路测(Minimization of Drive Test,MDT)中包含服务质量(Quality of Service,QoS)检验相关的测量,用于评估某一地区,某一时间下的通信是否满足QoS要求,如通信协议TS 37.320 5.2.1.1和5.4.1.1中M6所定义的测量为针对PDB的测量。以NR为例,介绍M6的测量量以及测量方式。
M6:上下行的数据包时延测量,针对每个UE的每个数据无线承载(Data Radio Bearer,DRB),具体的:
上行数据包时延:
D1:上行分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)时延,指的是UE侧测量的每个DRB的PDCP排队时延,即从PDCP包到达服务接入点(Service Access Point,SAP)上层到获取用于数据包传输的上行授权(UL grant)之间的时间间隔;
D2.1:空口时延,指的是从调度授权(grant)指示的传输时刻到成功接收到传输数据块的时间间隔;
D2.2:无线链路控制(Radio Link Control,RLC)时延,指的是RLC层从接收到包含第一个RLC服务数据单元(service data unit,SDU)的RLC协议数据单元(Protocol Data Unit,PDU)到将RLC SDU递交到PDCP层的时间间隔;
D2.3:F1-U接口上的时延,指的是将数据包从分布单元(Distributed Unit,DU)递交到集中单元(Centralized Unit,CU)的时间间隔;
D2.4:PDCP重排序时延,指的是PDCP层从接收PDCP PDU到将PDCP SDU递交到上层SAP的时间间隔;
因此,上行数据包时延定义为D1+D2.1+D2.2+D2.3+D2.4,其中D1由UE上报给RAN。
下行数据包时延:
D1:空口时延,指的是一个RLC SDU从到达媒体接入控制(Media Access Control,MAC)层至收到UE反馈成功接收该RLC SDU的时间间隔;
D2:gNB-DU上的时延,指的是一个RLC SDU从到达RLC层至递交到MAC层的时间间隔;
D3:F1-U接口上的时延,指的是将数据包从CU递交到DU的时间间隔;
D4:CU-UP接口上的时延,指的是从接收服务数据适应协议(Service Data Adaptation Protocol,SDAP)SDU到将PDCP SDU递交给DU的时间间隔;
因此,下行数据包时延定义为D1+D2+D3+D4。
需要说明的是,若业务传输不能满足survival time的需求,需要调整传输。而判断是否满足survival time的需求,是根据是否超过PDB决定的。现阶段UE不知道基站侧的PDB,基站根据UE上报获取包平均PDB,而平均PDB的统计时长基本为两次测量上报的时间间隔内的所有包的平均PDB值。通常,两次测量上报的时间间隔最小值为160ms。这远大于TSC业务需求(TSC业务周期最小为0.5ms,survival time可能就是周期的几个倍数,如10ms的量级)。因此,可能在第二次平均PDB还没上报的时候,就认为对端用的是上一次的PDB值,从而认为没有问题,但实际上的survival time已经超时 了。因此,需要考虑精确的PDB确定的方法,以保证传输性能。
基于上述问题,本申请提出了一种确定PDB的方案,可以精确的确定PDB。
以下通过具体实施例详述本申请的技术方案。
图2是根据本申请实施例的无线通信的方法200的示意性流程图,如图2所示,该方法200可以包括如下内容中的至少部分内容:
S210,第一设备向第二设备发送第一信息;其中,
该第一信息用于该第二设备确定以下至少之一:
消息损失(message loss),包损失(packet loss),消息对应的PDB,包对应的PDB,存活时间(survival time)不能满足,达到消息丢失不能忍受的时间周期或时间段或条件,达到包丢失不能忍受的时间周期或时间段或条件,触发满足业务传输的修改或重配或选择,触发重配或调度(例如,触发针对业务传输的重配或调度),上报存活时间不能满足,向对端请求业务传输的重配或修改,包传输延迟是否超过PDB;
S220,该第二设备接收该第一设备发送的该第一信息。
在本申请实施例中,第二设备可以基于第一信息确定以下至少之一:
消息损失(message loss),包损失(packet loss),消息对应的PDB,包对应的PDB,存活时间(survival time)不能满足,达到消息丢失不能忍受的时间周期或时间段或条件,达到包丢失不能忍受的时间周期或时间段或条件,触发满足业务传输的修改或重配或选择,触发重配或调度(例如,触发针对业务传输的重配或调度),上报存活时间不能满足,向对端请求业务传输的重配或修改,包传输延迟是否超过PDB。
从而,该第二设备可以精确的确定传输时延是否超过PDB,保证TSC业务的传输性能。
此外,在一些实施例中,该第一设备也可以是确定包传输延迟是否超过PDB。以及将包传输延迟是否超过PDB的结果指示给第二设备。
在一些实施例中,包传输延迟是否超过PDB,即包传输延迟是否超过一个特定时长,示例性的,该特定时长为PDCP丢弃时长(discard time)。
在一些实施例中,该第一信息为PDB信息,或者,该第一信息为包起始时间信息,或者,该第一信息为包到达信息,或者,该第一信息为反馈信息。
例如,该PDB信息由该第一设备测量或计算得到。
例如,该包起始时间信息由该第一设备测量或计算得到,或者,该包起始时间信息为该第一设备获取或保存的信息。
例如,该包到达信息为包到达PDCP层的时间。
