图2是根据本申请实施例的无线通信方法200的示意性流程图。该方法200可选地可以应用于图1所示的系统,但并不限于此。该方法200包括以下内容中的至少部分内容。
在210中,发送端针对第一分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)服务数据单元(Serving Data Unit,SDU)开启用于限制缓存时长的定时器。
具体地,在PDCP层,发送端可以针对每个来自高层的PDCP SDU分别开启丢弃定时器(Discard Timer)。其中,该丢弃定时器的时长是可以配置的。该丢弃定时器的目的在于防止对应的PDCP SDU在PDCP传输缓存中存放过长的时间导致不必要的缓存开销。当丢弃定时器到期时,相应的PDCP SDU可以进行丢弃。
应理解,本申请实施例中提到的发送端可以是系统100中的网络设备110,也可以是系统100中的终端设备120。
在220中,在该定时器到期时,发送端对包括该第一PDCP SDU的第一媒体接入控制MAC数据单元进行处理。
具体地,发送端在发送数据时,会针对媒体接入控制(Media Access Control,MAC)数据单元设置最大重传次数,如果传输一直失败,且在达到最大重传次数时,可以对缓存中存储的媒体接入控制(Media Access Control,MAC)数据单元进行清除。只有在达到最大重传次数时,才清除缓存中的数据,将会导致不必要的缓存开销。因为在达到最大重传次数时,在210中设置的针对PDCP SDU设置的定时器可能已经到期,也即针对PDCP SDU的重传已经没有意义。
因此,在本申请实施例中,在针对PDCP SDU设置的定时器到期时,对包括第一PDCP SDU的MAC数据单元进行处理,可以尽量避免不必要的缓存开销。
可选地,本申请实施例提到的最大重传次数可以为maxHARQ-Tx(最大混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)发送)参数,该参数可以是针对每个MAC实体(entity)配置的,其限制了每个HARQ进程对于MAC PDU的最大重传次数。每一个HARQ进程可以对应一个HARQ缓存(buffer)。对于同步上行HARQ,每一个HARQ进程可以维护一个状态变量CURRENT_TX_NB,该变量记录的是对于缓存在当前HARQ buffer中的MAC协议数据单元(Protocol Data Unit,PDU)已经传输的次数。在HARQ进程建立起来的时候,CURRENT_TX_NB需要置零。当CURRENT_TX_NB增加到maxHARQ-tx,对应的HARQ buffer需要清空。
可选地,本申请实施例可以用到数据预处理的场景。具体地,当终端设备在PDCP层收到高层递交的PDCP SDU时,可以对该PDCP SDU进行预处理,也即可以进行无线链路控制(Radio Link Control,RLC)层和MAC层的处理,在收到相应的处理命令(grant),且分配有空口传输资源时,即可以较快的生成传输块,并进行空口传输。而无需在收到相应的处理命令,才进行RLC层和MAC层的处理,可以节省处理时间。
为了更加清楚地理解本申请,以下将介绍在该定时器到期时,发送端如果对包括该第一PDCP SDU的第一媒体接入控制MAC数据单元进行处理。
在一种实现方式中,在该定时器到期时,且该第一MAC数据单元为未经过空口传输的第一MAC SDU时,丢弃该第一MAC SDU。
具体地,在该种实现方式中,如果针对第一PDCP SDU的定时器到期,且第一MAC数据单元还未进行PDU的封装,未分配空口传输资源,则可以清除HARQ buffer中的数据,直接丢失该第一MAC SDU。其中,如果第一MAC SDU包括除第一PDCP SDU之外的第二PDCP SDU时,可以对该第二PDCP SDU再次进行RLC和MAC层的处理。
可选地,将针对该第一MAC数据单元设置的最大重传次数进行清零。
具体地,因为已经丢弃第一MAC SDU,针对该MAC数据单元设置的最大重传次数已经没有用途,因此可以进行清零。
在一种实现方式中,在该定时器到期时,且该第一MAC数据单元为经过空口传输的第一MAC PDU时,判断该第一MAC PDU是否包括非该第一PDCP SDU的第二PDCP SDU;根据该第一MAC PDU是否包括该第二PDCP SDU,对该第一MAC PDU进行处理。
具体地,在该种实现方式中,如果针对第一PDCP SDU的定时器到期,且第一MAC数据单元已经进行PDU的封装且分配了空口传输资源,则需要判断第一MAC PDU是否封装有其他的PDCP SDU,根据是否有其他的PDCP SDU,来对第一MAC PDU进行处理。
可选地,在该第一MAC PDU不包括该第二PDCP SDU时,丢弃该第一MAC PDU。
具体地,如果第一MAC PDU不包括第二PDCP SDU,则意味着可以清除HARQ中的数据,丢弃该第一MAC PDU,因为第一PDCP SDU的定时器已经到期,无需缓存封装有该第一PDCP SDU的MAC PDU,而此时,该第一MAC PDU没有封装有其他PDCP SDU,直接丢弃该第一MAC PDU,不会对其他PDCP SDU的传输造成影响。
可选地,在该第一MAC PDU包括该第二PDCP SDU时,保留该第一MAC数据单元,以用于后续重传。
具体地,如果第一MAC PDU包括第二PDCP SDU,需要保留该第一MAC PDU,因为直接丢弃该第一MAC PDU,会对其他PDCP SDU的传输造成影响,而接收端到由于相应的定时器已经到期,第一PDCP SDU将会被接收端直接丢弃。
以上已经介绍了如何对MAC数据单元进行处理。以下将对RLC和PDCP层的处理进行说明。
可选地,丢弃在PDCP层缓存的该第一PDCP SDU。
可选地,丢弃在无线链路控制RLC层缓存的包括该第一PDCP SDU的RLC SDU。
因此,在本申请实施例中,在针对PDCP SDU设置的定时器到期时,对包括第一PDCP SDU的MAC数据单元进行处理,可以尽可能避免不必要的缓存开销。

可选地,该处理单元320进一步用于:
