Description

发送和接收数据的方法、装置和通信系统 技术领域
本申请实施例涉及无线通信技术领域。
背景技术
在通信系统中，有时会出现终端设备之间的资源抢占或终端设备内不同业务之间的资源抢占。
例如，当两个终端的下行空口时频域资源发生冲突时，网络设备优先保证两个终端设备里具有更高优先级的业务的传输，并通过特殊的下行控制信息(例如，DCI2-1)通知资源被抢占的终端设备。这种资源抢占机制使高优先级业务的数据以高的优先级发送，从而提升高优先级业务的实时性和可靠性。又例如，终端设备内部的资源抢占也可以基于业务的优先级进行。
对于被抢占的物理上行共享信道(PUSCH)许可，有可能已经产生数据，但数据仍然存在于混合自动重传请求(HARQ)的缓存中未发送。
此外，如果通信系统工作在非授权频段，终端设备和网络设备在发送数据之前需要监听非授权频段信道状况，进行信道接入评估，以保证不同设备共享信道资源的公平性。如果信道空闲则终端设备的物理层执行先听后说(LBT)成功，终端设备可以发送数据；如果信道被其他设备的信号占用，则物理层执行LBT失败，终端设备无法发送数据。所以，在执行LBT失败时，也存在产生数据但该数据未被发送的情况。这些未能被发送的数据如果不进行合理的处置可能会被丢弃，导致上行数据丢失。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
本申请的发明人发现，对一个未执行传输的配置许可(Configure Grant，CG)，由于CG是一种免授权的半静态资源许可，网络设备不知道终端设备中存在未被发送的CG的数据，因此，这些未被发送的CG的数据如果不进行合理的处置可能会被丢 弃，导致上行数据丢失。
如果一个CG的数据未执行传输，终端设备可以在下一个CG上发送未传输的媒体接入控制协议数据单元(MAC PDU)，该下一个CG的配置与未执行传输的CG的配置相同，其中，CG未传输是指根据该CG的配置产生的MAC PDU数据未被物理层发送。本申请的发明人发现，如果在下一个CG上发送未传输的MAC PDU之前，未传输的CG的配置发生了改变，例如，如果传输块大小(TB size)、HARQ进程或物理层优先级发生变化，则未传输的MAC PDU将无法被发送并会阻止后续新数据的传输。
图1是CG的配置发生变化的一个示意图。如图1所示，CG1被抢占或执行LBT失败而未执行传输，CG1上具有未发送的MAC PDU，该MAC PDU根据CG1的原有配置生成。在时刻T0，终端设备收到网络设备发送的CG配置激活指示，用于指示激活CG的新配置，并将CG的配置设置为该新配置，终端设备在时刻T1向网络设备发送CG配置激活确认，由于CG1的新配置相对于原配置发生了变化，终端设备在时刻T3无法使用CG1的新配置发送该未发送的MAC PDU。
本申请实施例提供一种发送和接收数据的方法、装置和通信系统，在根据第一CG的第一配置生成MAC PDU但没有在该第一CG上发送该MAC PDU的情况下，进行与未发送的该MAC PDU相关的处理，由此，能够避免未发送的MAC PDU的丢失或者阻碍后续新数据的传输，保证了数据传输的可靠性。

其中，所述终端设备具有根据所述第一配置许可(Configure Grant)的第一配置 生成的但未发送的媒体接入控制协议数据单元(MAC PDU)。
根据本申请实施例的第三方面，提供了一种发送数据的装置，应用于终端设备，该装置执行本申请实施例的第一方面的发送数据的方法。
根据本申请实施例的第四方面，提供了一种接收数据的装置，应用于网络设备，该装置执行本申请实施例的第二方面的接收数据的方法。

根据本申请实施例的第七方面，提供了一种通信系统，其具有本申请实施例的第五方面所述的终端设备以及第六方面所述的网络设备。
根据本申请实施例的第八方面，提供了一种计算机可读程序，其中当在发送数据的装置或终端设备中执行所述程序时，所述程序使得所述发送数据的装置或终端设备执行本申请实施例的第一方面的发送数据的方法。
根据本申请实施例的第九方面，提供了一种存储有计算机可读程序的存储介质，其中所述计算机可读程序使得发送数据的装置或终端设备执行本申请实施例的第一方面所述的发送数据的方法。
根据本申请实施例的第十方面，提供了一种计算机可读程序，其中当在接收数据的装置或网络设备中执行所述程序时，所述程序使得所述接收数据的装置或网络设备执行本申请实施例的第二方面所述的接收数据的方法。
根据本申请实施例的第十一方面，提供了一种存储有计算机可读程序的存储介质，其中所述计算机可读程序使得接收数据的装置或网络设备执行本申请实施例的第二方面所述的接收数据的方法。
本申请实施例的有益效果在于：能够避免未传输CG的MAC PDU阻止后续新数据的传输，保证了数据传输的可靠性。

在本申请的下述各实施例中，CG未传输是指根据该CG的配置产生的MAC PDU数据未被物理层发送，该MAC PDU也可以被称为未发送的MAC PDU。
实施例的第一方面
本申请实施例的第一方面涉及一种发送数据的方法，应用于终端设备，例如终端设备202。
首先对本申请的应用场景进行说明。
终端设备内部的传输冲突可能出现在不同的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)资源许可之间，例如出现在两个半静态的配置许可 (Configure Grant，CG)的PUSCH之间，或出现在CG的PUSCH和动态调度的PUSCH之间。对于PUSCH资源许可和不同的调度请求(SR)传输或肯定应答(ACK)/否定应答(NACK)指示之间产生的冲突，终端设备优先保证高优先级业务的PUSCH、SR或ACK/NACK的传输。终端设备的MAC层这样保证高优先级业务优先传输：根据逻辑信道优先级确定优先传输的PUSCH许可或SR传输。在一个PUSCH传输块复用多个逻辑信道数据的情况下，该PUSCH许可的优先级由传输块内复用的最高优先级的逻辑信道决定，一个SR传输的优先级由该SR对应的逻辑信道优先级决定。在两个或多个资源冲突的情况下，优先级最高的PUSCH许可或优先级最高的SR被确定为高优先级并被MAC层优先传输，其他许可或SR传输被确定为低优先级并被抢占。
如果网络设备给终端设备配置授权许可(Configured Grant)，网络设备向终端设备发送CG配置信息，CG配置信息指示一个CG的上行资源授权、调制预编码策略(MCS)、HARQ进程、物理层优先级和CG定时器等。其中，物理层优先级是该CG配置的上行许可在物理层的抢占优先级，如果MAC层指示物理层传输对应于两个重叠的上行许可的MAC PDU，物理层优先传输物理层优先级高的上行许可的MAC PDU。上行资源授权包括该上行资源的频域资源位置、资源周期、资源持续时间和资源在周期内的偏移等，其中，资源在周期内的偏移以正交频分复用(OFDM)符号、时隙或子帧为单位。
在超高可靠与低时延通信(Ultra-reliable and Low Latency Communications，URLLC)技术中，在配置许可的传输机会上，终端设备可以使用至少一个HARQ进程，其中，HARQ进程由HARQ进程号标识。网络设备可以给终端设备配置一个以上CG，针对每个CG可以配置一个以上HARQ进程。与一个CG相关的HARQ进程由下面的公式(1)确定：
HARQ Process ID＝[floor(CURRENT_symbol/periodicity)]modulo nrofHARQ-Processes+harq-procID-offset          (1)
其中，CURRENT_symbol是该CG的第一个符号，periodicity是该CG的周期，nfofHARQ-Processes是该CG的HARQ进程数，harq-procID-offset是该CG的HARQ进程ID的偏移。
网络设备对每个逻辑信道配置有允许使用的CG，一个逻辑信道对应可使用的一个或多个CG，每个CG也可以对应一个或多个逻辑信道。终端设备可根据该CG中可 以复用的最高优先级的逻辑信道确定该CG的优先级，再根据该CG的优先级确定该CG是优先传输的上行许可(高优先级的上行许可)还是被抢占的上行许可(低优先级的上行许可)，例如：如果没有其他更高优先级CG的PUSCH与该CG的PUSCH在时间上重叠，并且没有其他更高优先级动态调度许可的PUSCH在时间上与该CG的PUSCH重叠，并且没有其他更高优先级SR传输的PUCCH与该CG的PUSCH在时间上重叠重叠，则该CG为高优先级的上行许可，其他重叠的上行许可为低优先级的上行许可。
如果该CG是一个高优先级的上行许可，终端设备可以从复用和封装实体获取MAC PDU并使该CG相关的HARQ进程触发新数据传输。此外，终端设备还可以启动该HARQ进程的CG定时器。如果该CG是一个低优先级的上行许可，则终端设备不获取MAC PDU并且不触发新数据的传输。对于暂时确定为高优先级的CG，终端设备已获取了MAC PDU并触发了新数据传输，但是在更高优先级的逻辑信道数据到来的时候终端设备可能将该CG确定为一个低优先级的许可。所以，一个低优先级的许可可能已经获取了MAC PDU，也可能未获取MAC PDU。
图3是本申请实施例的第一方面的发送数据的方法的一个示意图，如图3所示，该发送数据的方法可以包括：
操作301、获取根据第一配置许可(Configure Grant，CG)的第一配置生成的但没有发送的媒体接入控制协议数据单元(MAC PDU)；以及
操作303、进行与未发送的所述媒体接入控制协议数据单元(MAC PDU)相关的处理。
在本实施例的第一方面中，在根据第一CG的第一配置生成MAC PDU但没有在该第一CG上发送该MAC PDU的情况下，进行与未发送的该MAC PDU相关的处理，由此，能够避免该未发送的MAC PDU的丢失或避免该未发送的MAC PDU阻碍后续新数据的传输，保证了数据传输的可靠性。
如图3所示，该方法还可以包括：
操作302、接收第一配置许可的第二配置的激活指示。
例如，操作302可以接收由网络设备201发送的第一配置许可的第二配置的激活指示。
在至少一个实施例中，可以在第二配置相对于第一配置发生改变的情况下，进行 上述的操作303，由此，在第二配置相对于第一配置发生改变而无法在下一个CG上发送该未发送的MAC PDU的情况下，避免该未发送的MAC PDU的丢失或避免该未发送的MAC PDU阻碍后续新数据的传输。
第二配置相对于第一配置发生的改变包括：配置许可(CG)的传输块大小(TB size)的改变，和/或配置许可的配置所支持的混合自动重传(HARQ)进程的改变，和/或配置许可的物理层优先级的改变等。
第二配置相对于第一配置的改变可以由第二配置的参数相对于第一配置的参数的改变所引起。例如，上行资源授权参数或调制与编码策略(MCS)参数的改变可以引起配置许可的输块大小(TB size)的改变；又例如，混合自动重传(HARQ)进程参数的改变可以引起配置许可的配置所支持的混合自动重传(HARQ)进程的改变由；又例如，物理层优先级参数的改变能够引起配置许可的物理层优先级的改变。
在至少一个实施例中，操作303的与未发送的媒体接入控制协议数据单元(MAC PDU)相关的处理可以是如下的处理1～处理4中的至少一种处理。
处理1、
处理1包括：终端设备202向网络设备202发送指示信息，该指示信息用于指示操作301中获取的媒体接入控制协议数据单元(MAC PDU)未发送。
根据处理1，如果第一CG已根据第一配置产生MAC PDU但未发送，当终端设备无法使用第一CG的第一配置重新发送该未发送的MAC PDU时，或者，第一CG的配置改变为第二配置，终端设备无法使用第一CG的第二配置发送未发送的MAC PDU时，终端设备可以向网络设备发送指示信息，网络设备可以根据该指示信息进行调度，以重新发送该未发送的MAC PDU。
在处理1中，对于第一CG是被抢占的CG，或第一CG是执行LBT失败的CG，处理1的具体实施方式可以不同。
在第一CG是被抢占的CG的情况下，即，在第一CG的优先级低于其他许可的优先级而未发送MAC PDU的情况下，在至少一个实施例中，终端设备202的物理层在第一CG的上行资源上发送该指示信息。由此，网络设备201收到该指示信息后即可获知该第一CG的配置信息以及相关的HARQ进程标识，终端设备202无需指示该被抢占的第一CG的其他信息，因此指示信息的信令开销较少。
例如，终端设备202的物理层在未发送的MAC PDU对应的上行资源上发送解调 参考信号(DMRS)或发送该MAC PDU的部分上行数据作为该指示信息；又例如，终端设备202的物理层使用与未发送的该MAC PDU相同的混合自动重传(HARQ)进程和第一配置许可(CG)的配置发送该指示信息。
在第一CG是被抢占的CG的情况下，即，在第一CG的优先级低于其他许可的优先级而未发送MAC PDU的情况下，在至少另一个实施例中，终端设备202可以通过物理上行控制信道(PUCCH)、媒体接入控制层控制元件(MAC CE)或无线资源控制(RRC)信令发送该指示信息。
例如，终端设备202可以通过高优先级的PUCCH、MAC CE或RRC信令传输该指示信息，其中，该指示信息中可以携带该第一CG的配置标识以及未发送的该MAC PDU使用的混合自动重传请求(HARQ)的进程标识(ID)等。其中，高优先级例如可以是比第一CG的优先级高的优先级。由于使用高优先级的信令发送该指示信息，该指示信息的实时性比较高，能及时调度第一CG的第一配置生成的MAC PDU。
在第一CG执行LBT失败的情况下，即，在该第一CG由于执行LBT失败而导致MAC PDU未发送的情况下，在至少一个实施例中，终端设备202的物理层在第一CG的上行资源上发送该指示信息。由此，网络设备201收到该指示信息后即可获知该第一CG的配置信息以及相关的HARQ进程标识，终端设备202无需指示执行LBT失败的该第一CG的其他信息，因此指示信息的信令开销较少。
例如，终端设备202的物理层在未发送的MAC PDU对应的上行资源上发送解调参考信号(DMRS)或发送该MAC PDU的部分上行数据作为所述指示信息，由此，网络设备201能够及时获取该第一CG执行LBT失败的情况，从而能够及时调度未传输的MAC PDU。又例如，终端设备202的物理层用未发送的MAC PDU所使用的混合自动重传(HARQ)进程和该第一CG的配置发送该指示信息。
在第一CG执行LBT失败的情况下，即，在该第一CG由于执行LBT失败而导致MAC PDU未发送的情况下，在至少另一个实施例中，终端设备202通过物理上行控制信道(PUCCH)、媒体接入控制层控制元件(MAC CE)或无线资源控制(RRC)信令发送该指示信息。
例如，终端设备202可以通过高优先级的PUCCH、MAC CE或RRC信令传输该指示信息，其中，该指示信息中可以携带执行LBT失败的该第一CG的配置标识 以及未发送的该MAC PDU使用的混合自动重传请求(HARQ)的进程标识(ID)等。其中，高优先级例如可以是比第一CG的优先级高的优先级。由于使用高优先级的信令发送该指示信息，能够提高LBT成功的可能性，并且，该指示信息的实时性比较高，能使网络设备及时调度第一CG的第一配置生成的MAC PDU。
在处理1中，终端设备202可以在确定该第一CG为低优先级时，或者在确定该第一CG执行LBT失败时，向网络设备发送该指示信息。此外，本申请可以不限于此，例如，终端设备202也可以在收到该第一CG的该第二配置的激活指示时，如果第二配置相对于第一配置发生改变，则向网络设备201发送该指示信息。
图4是在处理1中终端设备和网络设备进行通信的一个示意图。如图4所示，在处理1中，终端设备202和网络设备201的通信包括：
操作401、终端设备202向网络设备201发送上述的指示信息；
操作402、网络设备201向终端设备202发送调度信息，该调度信息用于调度未传输的MAC PDU进行重传。
处理2、
在处理2中，终端设备202使用第二配置许可(CG)对未发送的MAC PDU进行发送。
根据处理2，如果第一CG已根据第一配置产生MAC PDU但未发送，当终端设备无法使用第一CG的第一配置重新发送该未发送的MAC PDU时，或者，该第一CG的配置改变为第二配置，终端设备无法使用第一CG的第二配置发送未发送的MAC PDU时，则终端设备可以使用第二CG(即，第一CG之外的其它CG)发送该MAC PDU。
在处理2中，第二CG的传输块大小(TB size)与未发送的MAC PDU的大小相同。由此，保证第二CG能够用来发送该未发送的MAC PDU。
例如，第二CG的调制与编码策略(MCS)参数与第一CG的第一配置的调制与编码策略(MCS)参数相同，并且，第二CG的上行资源大小与第一CG的第一配置的上行资源大小相同。
在处理2中，未发送的MAC PDU中复用的逻辑信道支持使用第二CG；或者，第一CG的物理层优先级与第二CG的物理层优先级一致；或者，第二CG支持未发送的MAC PDU使用的混合自动重传请求(HARQ)进程。由此，进一步保证第二 CG能够用来发送该未发送的MAC PDU。
在处理2中，终端设备202可以用与未发送的MAC PDU使用的HARQ进程相同或不同的HARQ进程来发送未发送的MAC PDU。
在处理2中，终端设备202可以在不同的时机确定用第二CG对未发送的MAC PDU进行发送。
在至少一个实施例中，终端设备202在收到第一CG的第二配置的激活指示时，确定使用第二CG发送该未发送的MAC PDU。由此，即使第二配置相对于第一配置发生变化，也不会影响该未发送的MAC PDU的发送。
其中，终端设备收到针对第一CG的第二配置的配置激活指示，例如是指：终端设备202收到Type-2CG配置激活指示，即，终端设备202收到小区无线网络临时标识(CS-RNTI)加扰的物理下行控制信道(PDCCH)，该PDCCH指示的NDI＝0并且该PDCCH的内容指示了激活Type 2CG配置。
图5是处理2中终端设备和网络设备通信的一个示意图，如图5所示，处理2包括：
操作501、终端设备接收网络设备发送的第一CG的第二配置的激活指示；
操作502、触发对第二配置的激活的确认，以及按照第二配置对第一CG进行初始化；
操作503、终端设备将未发送的MAC PDU转移到第二CG的混合自动重传请求(HARQ)进程缓存中；
操作504、终端设备向网络设备发送第二配置的激活的确认；
操作505、使用第二CG发送未发送的MAC PDU。
例如，在第二配置的参数相对于第一配置的参数发生改变，并且该第一CG下的HARQ进程中有HARQ进程中存在未传输的CG，即该HARQ进程已获取了MAC PDU但未发送的情况下，终端设备202可以进行操作503，即，将该MAC PDU转移到第二CG相关的HARQ进程缓存中。此外，终端设备还可以在操作502中触发对第一CG的第二配置的激活的确认，并在操作502中按照激活的第二配置对第一CG进行初始化。
在本申请中，对于操作502、操作503的顺序不做限定，对于操作504和操作505的顺序也不做限定。例如，可以按照操作503、操作502、操作504、操作505的顺 序依次进行，或者，操作502、操作503、操作505、操作504的顺序进行，或者，按照操作502、操作503、操作504、操作505的顺序依次进行等。
图6是处理2的一个时序图。如图6所示，第一CG被抢占或执行LBT失败而未执行传输，第一CG上具有未发送的MAC PDU，该MAC PDU根据第一CG的第一配置生成。在时刻T0，终端设备202收到网络设备201发送的CG配置激活指示，用于指示激活第一CG的第二配置，终端设备202按照激活的第二配置对第一CG进行初始化。终端设备202在时刻T1向网络设备201发送第一CG的第二配置的激活的确认。由于第一CG的第二配置相对于第一配置发生了变化，终端设备202无法使用第一CG(即，CG 1)的第二配置发送该未发送的MAC PDU，而是在时刻T2使用第二CG(即，CG 2)发送该未发送的MAC PDU。
需要说明的是，在图6中，时刻T2、T1只是示意，例如，T2可以早于T1，或者，T2可以晚于T1，或者，T2与T1可以同时。
图7是在处理2中终端设备处理流程的一个示意图。如图7所示，在处理2中，终端设备的处理包括：
操作701、终端设备在为第一CG获取MAC PDU时，如果第一CG的配置与该未发送的MAC PDU不匹配，将未发送的MAC PDU转移到第二CG的混合自动重传请求(HARQ)进程缓存中；
操作702、终端设备使用第二CG发送未发送的MAC PDU。
在至少另一个实施例中，终端设备202可以在第一CG获取要发送的MAC PDU时，确定使用第二CG发送该未发送的MAC PDU。由此，即使第一配置发生变化，也不会影响该未发送的MAC PDU的发送。
例如，在终端设备为第一CG获取MAC PDU时，如果该第一CG的混合自动重传(HARQ)进程的上一个CG为低优先级的许可或执行LBT失败的许可，并且所述混合自动重传(HARQ)进程已经获取了MAC PDU，如果第一CG的配置与该获取的MAC PDU不匹配，终端设备可以进行操作701，即，将未发送的MAC PDU转移到第二配置许可的混合自动重传请求(HARQ)进程缓存中。
图8是处理2的另一个时序图。如图8所示，第一CG被抢占或执行LBT失败而未执行传输，第一CG上具有未发送的MAC PDU，该MAC PDU根据第一CG的 第一配置生成。
在时刻T0，终端设备202收到网络设备201发送的CG配置激活指示，用于指示激活第一CG的第二配置，终端设备202按照激活的第二配置对第一CG进行初始化。终端设备202在时刻T1向网络设备201发送第一CG的第二配置的激活的确认。
在时刻T3，第一CG的混合自动重传请求进程(HARQ process)0获取了该未发送的MAC PDU，并且，该第一CG的上一个CG(即，也是第一CG)是未传输的许可，由于第一CG的第二配置相对于第一配置发生了变化，终端设备202无法使用第一CG的第二配置发送该未发送的MAC PDU，因此，将MAC PDU转移到第二CG的HARQ process 1的缓存中。在时刻T4，终端设备202使用第二CG对该未传输的PDU进行发送。
处理3、
在处理3中，终端设备202清除第一CG的混合自动重传(HARQ)进程的缓存，或者，终端设备202清除第一CG的HARQ进程中有未发送的MAC PDU的混合自动重传请求(HARQ)进程的缓存。
其中，有未发送的MAC PDU的混合自动重传请求(HARQ)进程是指：该HARQ进程的上一个CG为低优先级的配置许可(CG)或执行LBT失败的配置许可(CG)，并且该HARQ进程已获取了上一个CG的未发送的MAC PDU。
根据处理3，清除未发送的MAC PDU，能够避免相关的HARQ进程无法发送新数据。
在处理3中，终端设备202可以在不同的时机清除该未发送的MAC PDU。
在至少一个实施例中，终端设备202在收到第一CG的第二配置的激活指示时，清除该未发送的MAC PDU。
其中，终端设备收到针对第一CG的第二配置的配置激活指示，例如是指：终端设备202收到Type-2CG配置激活指示，即，终端设备202收到配置调度无线网络临时标识(CS-RNTI)加扰的物理下行控制信道(PDCCH)，该PDCCH指示的NDI＝0并且该PDCCH的内容指示了激活Type 2CG配置。
在处理3中，终端设备202在收到第一CG的第二配置的激活指示时，如果第一CG的第二配置相对于第一配置发生改变，那么：终端设备202清除第一CG下的HARQ进程的缓存，或者，终端设备202只是清除第一CG的HARQ进程中有未发 送的MAC PDU的混合自动重传请求(HARQ)进程的缓存。
其中，终端设备202清除第一CG的HARQ进程中有未发送的MAC PDU的混合自动重传请求(HARQ)进程的缓存，例如是：终端设备202收到CG配置激活指示时，如果第一CG的第二配置相对于第一配置发生改变，并且该第一CG下的HARQ进程中有HARQ进程的上一个CG为被抢占的许可(即，该上一个CG为低优先级的CG)，该HARQ进程已获取了MAC PDU或者该HARQ进程有未传输的PDU，则清空该HARQ进程的缓存。
图9是处理3中网络设备和终端设备通信的一个示意图，如图9所示，处理3包括：
操作901、终端设备接收网络设备发送的第一CG的第二配置的激活指示；
操作902、终端设备触发对第二配置的激活的确认，以及按照第二配置对第一CG进行初始化；
操作903、终端设备清除第一CG的HARQ进程的缓存，或者，清除第一CG的HARQ进程中有未发送的MAC PDU的HARQ进程的缓存；
操作904、发送用于指示已收到所述第二配置的激活指示的激活的确认。
在本申请中，对于操作902和操作903的顺序不做限定。例如，可以按照操作902、903的顺序依次进行，也可以先执行操作903再执行操作902。
图10是处理3的一个时序图。如图10所示，第一CG被抢占或执行LBT失败而未执行传输，第一CG上具有未发送的MAC PDU，该MAC PDU根据第一CG的第一配置生成。在时刻T0，终端设备202收到网络设备201发送的CG配置激活指示，用于指示激活第一CG的第二配置，终端设备202按照激活的第二配置对第一CG进行初始化。第二配置相对于第一配置发生了变化。终端设备202在时刻T1向网络设备201发送第一CG的第二配置的激活的确认。如图10所示，终端设备202在时刻T0进行处理3，即，清除未发送的MAC PDU。
在至少另一个实施例中，终端设备202可以在第一CG的混合自动重传请求(HARQ)进程获取媒体接入控制协议数据单元(MAC PDU)时，清除该HARQ进程的缓存。
例如，在终端设备为第一CG获取MAC PDU时，如果第一CG的混合自动重传 请求(HARQ)进程的上一个CG为低优先级的CG或执行LBT失败的CG，并且该HARQ进程已经获取了MAC PDU的情况下：如果该第一CG的配置与该MAC PDU不匹配，例如，该第一CG的传输块大小与该MAC PDU的大小不相同，则终端设备202终端设备202获取新的MAC PDU以清除该HARQ进程的缓存(即清除未发送的MAC PDU)；此外，如果该第一CG的配置与该MAC PDU相匹配，则终端设备202认为该HARQ进程已获取MAC PDU，则可以对该MAC PDU进行发送。
图11是处理3的另一个时序图。如图11所示，第一CG被抢占或执行LBT失败而未执行传输，第一CG上具有未发送的MAC PDU，该MAC PDU根据第一CG的第一配置生成。在时刻T0，终端设备202收到网络设备201发送的CG配置激活指示，用于指示激活第一CG的第二配置，第二配置相对于第一配置发生了变化，终端设备202按照激活的第二配置对第一CG进行初始化。终端设备202在时刻T1向网络设备201发送第一CG的第二配置的激活的确认。。
如图11所示，在时刻T2，下一个第一CG的HARQ进程获取前一个CG的未发送的MAC PDU。由于无法发送未发送的MAC PDU，终端设备202在时刻T2进行处理3，即，清除未发送的MAC PDU。
处理4、
处理4包括：终端设备202使用第一配置许可(CG)发送未发送的媒体接入控制协议数据单元(MAC PDU)。在处理4中，终端设备202可以仍然使用第一CG来发送未发送的MAC PDU。
处理4的实施方式一：
在实施方式一中，终端设备202使用第一配置许可(CG)的第一配置发送未发送的媒体接入控制协议数据单元(MAC PDU)，并且，在对未发送的MAC PDU发送完成之后，触发对第二配置的激活的确认。
图12是在处理4的实施方式一中终端设备和网络设备进行通信的一个示意图。如图12所示，在处理4的实施方式一中，终端设备202和网络设备201的通信包括：
操作1201、终端设备202收到网络设备201发送的第一CG的第二配置的激活指示；
操作1202，终端设备202使用第一CG的第一配置向网络设备201发送所述未传输的MAC PDU；
操作1203、终端设备202触发所述第二配置的激活确认；
操作1204、终端设备202向网络设备201发送用于指示已收到所述第二配置的激活指示的配置激活确认；以及
操作1205、终端设备202根据第二配置对第一CG进行初始化。
例如，在终端设备202收到第二配置的激活指示时，如果有第二配置相对于第一配置发生改变，并且该第一CG下的HARQ进程中有HARQ进程的上一个CG为被抢占的许可或LBT失败的CG，而该HARQ进程已获取了MAC PDU，则在该MAC PDU传输完成后触发针对第二配置激活的确认，并发送用于指示已收到该第二配置的激活指示的配置激活确认，并按照激活的第二配置对后续的第一CG进行初始化。
网络设备201在收到终端设备202发送的CG配置激活的确认时，认为终端设备202已激活了第二配置，因而网络设备201可以按照激活的第二配置对后续的CG进行初始化。由此，推迟激活第二配置，即使第二配置相对于第一配置发生变化，也不会影响未传输的MAC PDU的重传，而且网络设备和终端设备可以同步激活第二CG配置。
图13是处理4的实施方式一的一个时序图。如图13所示，第一CG被抢占或执行LBT失败而未执行传输，第一CG上具有未发送的MAC PDU。在时刻T0，终端设备202收到网络设备201发送的CG配置激活指示，用于指示激活第一CG的第二配置，第二配置相对于第一配置发生了变化。在时刻T1，终端设备202使用第一CG的第一配置发送之前未发送的MAC PDU，并在发送MAC PDU完成之后，触发配置激活的确认。在时刻T2，终端设备202向网络设备201发送第一CG的第二配置的激活的确认。此外，终端设备202按照激活的第二配置对第一CG进行初始化。
处理4的实施方式二：
在实施方式二中，终端设备202在收到第二配置的激活指示之后，触发对第二配置的激活的确认，并且，使用第一配置许可(CG)的第一配置发送未发送的媒体接入控制协议数据单元(MAC PDU)。
实施方式二的方法一：
图14是在处理4的实施方式二的方法一中终端设备和网络设备进行通信的一个示意图。如图14所示，在处理4的实施方式二中，终端设备202和网络设备201的 通信包括：操作1401、终端设备202接收网络设备201发送的第一CG的第二配置的激活指示；
操作1402、终端设备202，触发所述第二配置的激活确认；
操作1403、终端设备202使用第一CG的第一配置向网络设备201发送所述未传输的MAC PDU；以及
操作1404、终端设备202根据第二配置对第一CG进行初始化；
操作1405、终端设备202向网络设备201发送用于指示已收到所述第二配置的激活指示的配置激活确认。
例如，在终端设备202收到第二配置的激活指示时，如果有第二配置相对于第一配置发生改变，并且该第一CG下的HARQ进程中有HARQ进程的上一个CG为被抢占的许可或LBT失败的CG，而该HARQ进程已获取了MAC PDU，则终端设备202暂时不产生针对第二配置激活的确认。在将未发送的MAC PDU发送完成之后，再产生用于指示已收到该第二配置的激活指示的配置激活确认并发送，并且按照激活的第二配置对后续的CG进行初始化。
网络设备201在收到终端设备202发送的CG配置激活的确认时，认为终端设备202已激活了第二配置，因而网络设备201可以按照激活的第二配置对后续的CG进行初始化。由此，推迟激活第二配置，即使第二配置相对于第一配置发生变化，也不会影响未传输的MAC PDU的重传，而且网络设备和终端设备可以同步激活第二CG配置。
此外，对于根据第二配置对第一CG进行初始化的步骤1404和发送配置激活确认的步骤1405的先后顺序不做限定。
图15是处理4的实施方式二的方法一的一个时序图。如图15所示，第一CG被抢占或执行LBT失败而未执行传输，第一CG上具有未发送的MAC PDU。在时刻T0，终端设备202收到网络设备201发送的CG配置激活指示，用于指示激活第一CG的第二配置，第二配置相对于第一配置发生了变化。在时刻T0，终端设备202触发配置激活的确认。在时刻T1，终端设备202使用第一CG的第一配置发送之前未发送的MAC PDU。在时刻T2，终端设备202向网络设备201发送第一CG的第二配置的激活的确认。此外，终端设备202按照激活的第二配置对第一CG进行初始化。
实施方式二的方法二：
图16是在处理4的实施方式二的方法二中终端设备和网络设备进行通信的一个示意图。如图16所示，在处理4的实施方式二的方法二中，终端设备202和网络设备201的通信包括：操作1601、终端设备202接收网络设备201发送的第一CG的第二配置的激活指示；
操作1602、终端设备202触发所述第二配置的激活确认；
操作1603、在使用第一配置许可的第一配置发送未传输的媒体接入控制协议数据单元(MAC PDU)之前，终端设备202发送用于指示未收到所述第二配置的激活指示的激活确认；
操作1604、终端设备202使用第一配置许可的第一配置向网络设备201发送未传输的媒体接入控制协议数据单元(MAC PDU)；以及
操作1605、终端设备202根据第二配置对所述第一配置许可进行初始化；
操作1606、终端设备202向网络设备201发送用于指示已收到所述第二配置的激活指示的激活确认。
例如，在终端设备202收到第二配置的激活指示时，如果有第二配置相对于第一配置发生改变，并且该第一CG下的HARQ进程中有HARQ进程的上一个CG为被抢占的许可或LBT失败的CG，而该HARQ进程已获取了MAC PDU，则终端设备202产生指示未收到该配置激活指示的第一CG配置激活确认并发送。网络设备在收到终端设备发送的第一CG配置激活确认时，认为终端设备该未激活第二配置。在将未发送的MAC PDU发送完成之后，终端设备再产生用于指示已收到该第二配置的激活指示的配置激活确认并发送，并且按照激活的第二配置对后续的CG进行初始化。
网络设备201在收到终端设备202发送的CG配置激活的确认时，认为终端设备202已激活了第二配置，因而网络设备201可以按照激活的第二配置对后续的CG进行初始化。由此，推迟激活第二配置，即使第二配置相对于第一配置发生变化，也不会影响未传输的MAC PDU的重传，而且网络设备和终端设备可以同步激活第二配置。
此外，在本实施例中，对于根据第二配置对第一CG进行初始化的步骤1605和发送配置激活确认的步骤1606的先后顺序不做限定。
图17是处理4的实施方式二的方法二的一个时序图。如图17所示，第一CG被抢占或执行LBT失败而未执行传输，第一CG上具有未发送的MAC PDU。在时刻 T0，终端设备202收到网络设备201发送的CG配置激活指示，用于指示激活第一CG的第二配置，第二配置相对于第一配置发生了变化。在时刻T0，终端设备202触发配置激活的确认。在时刻T01，终端设备202发送指示未收到第二配置的配置激活指示。在时刻T1，终端设备202使用第一CG的第一配置发送之前未发送的MAC PDU。在时刻T2，终端设备202向网络设备201发送第一CG的第二配置的配置激活的确认。此外，终端设备202按照激活的第二配置对第一CG进行初始化。
图18是在处理4的实施方式二的方法二中终端设备和网络设备进行通信的另一个示意图。如图18所示，在处理4的实施方式二的方法二中，终端设备202和网络设备201的通信包括：
操作1801、终端设备202接收网络设备201发送的第一CG的第二配置的激活指示；
操作1802、终端设202触发所述第二配置的激活确认；
操作1803、在使用第一配置许可的第一配置发送未传输的媒体接入控制协议数据单元(MAC PDU)之前，终端设备202向网络设备201发送用于指示未收到所述第二配置的激活指示的激活确认；
操作1804、终端设备202取消触发对第二配置的激活确认；以及
操作1805、终端设备202使用第一配置许可的第一配置向网络设备201发送未传输的媒体接入控制协议数据单元(MAC PDU)。
例如，在终端设备202收到第二配置的激活指示时，如果有第二配置相对于第一配置发生改变，并且该第一CG下的HARQ进程中有HARQ进程的上一个CG为被抢占的许可或LBT失败的CG，而该HARQ进程已获取了MAC PDU，则终端设备202产生指示未收到该配置激活指示的第一CG配置激活确认并发送，并且，终端设备202可以取消触发对第二配置激活的确认。网络设备在收到终端设备发送的第一CG配置激活确认时，认为终端设备该未激活第二配置。在将未发送的MAC PDU发送完成之后，如果终端设备202再收到收到CG配置激活指示，由于该第一CG下已不存在未传输的MAC PDU，因此，终端设备202可以触发CG配置激活的确认，产生并发送该CG配置激活的确认，用于指示已收到该CG配置激活指示。然后终端设备202按照激活的CG配置对后续的CG进行初始化。网络设备201在收到终端设备202发送的CG配置激活的确认时，认为终端设备202已激活了新的配置，因而网络 设备201可以按照激活的配置对后续的CG进行初始化。由此，推迟产生配置激活的确认，即使新的配置相对于第一配置发生变化，也不会影响未传输的MAC PDU的重传，而且网络设备和终端设备可以同步激活新的配置。
图19是处理4的实施方式二的方法二的另一个时序图。与图22对应。如图23所示，第一CG被抢占或执行LBT失败而未执行传输，第一CG上具有未发送的MAC PDU。在时刻T0，终端设备202收到网络设备201发送的CG配置激活指示，用于指示激活第一CG的第二配置，第二配置相对于第一配置发生了变化。在时刻T0，终端设备202触发配置激活的确认。在时刻T01，终端设备202发送指示未收到第二配置的配置激活确认，并且取消触发配置激活确认。在时刻T1，终端设备202使用第一CG的第一配置发送之前未发送的MAC PDU。在时刻T11，终端设备202收到新的配置激活指示，终端设备202触发配置激活确认。在时刻T2，终端设备202向网络设备201发送第一CG的新的配置的配置激活的确认，终端设备202按照激活的新的配置对第一CG进行初始化。
处理4的实施方式三：
在实施方式三中，终端设备202使用第一配置许可(CG)的第二配置发送未发送的媒体接入控制协议数据单元(MAC PDU)。
图20是处理4的实施方式三的一个示意图，如图20所示，该处理4包括：
操作2001、收到所述第一配置许可的第二配置的激活指示；
操作2002、触发第二配置的激活确认，并且根据所述第二配置对所述第一配置许可进行初始化；以及
操作2003、使用所述第一配置许可的第二配置发送所述未传输的媒体接入控制协议数据单元(MAC PDU)。
由此，即使第二配置相对于第一配置改变，终端设备202也可以用第二配置发送未发送的MAC PDU。
例如，如果上行资源授权参数或MCS参数改变导致的CG配置的TB size变化，可以通过适当的方式用第二配置发送未发送的MAC PDU。比如，如果第一配置许可的第二配置的传输块大小比未发送的媒体接入控制协议数据单元(MAC PDU)的传输块大小更大，可以将未发送的媒体接入控制协议数据单元(MAC PDU)进行比特重复，使该未发送的MAC PDU的传输块大小与第二配置的传输块大小相同；又比如， 如果第一配置许可的第二配置的传输块大小比未发送的MAC PDU的传输块大小更小，可以将该未发送的MAC PDU进行比特打孔，使该未发送的MAC PDU的传输块大小与第二配置的传输块大小相同。
又例如，如果第一配置许可的第二配置不支持未发送的媒体接入控制协议数据单元(MAC PDU)使用的混合自动重传请求(HARQ)进程，则终端设备202可以使用第二配置的混合自动重传请求(HARQ)进程发送发送未发送的媒体接入控制协议数据单元(MAC PDU)。
再例如，如果第一配置许可的第二配置的物理层优先级的不同于未发送的媒体接入控制协议数据单元(MAC PDU)对应的上行许可的物理层优先级，终端设备202可以使用第二配置的物理层优先级发送该未发送的媒体接入控制协议数据单元(MAC PDU)。
处理4的实施方式四：
在实施方式四中，终端设备202使用第一配置许可(CG)的第一配置发送未发送的媒体接入控制协议数据单元(MAC PDU)。
如果第一配置许可(CG)的混合自动重传请求(HARQ)进程的上一个配置许可为低优先级的许可或执行LBT失败的许可，并且HARQ进程已经获取了MAC PDU，终端设备202认为该HARQ进程已获取MAC PDU，并且，终端设备202可以将该MAC PDU和配置许可交给该HARQ进程进行发送。
在本申请实施例的第一方面，终端设备202可以使用上述处理1～处理4中的至少一者，或者两者以上的组合，对未发送的媒体接入控制协议数据单元(MAC PDU)进行处理。
在至少一个实施例中，终端设备202可以向网络设备201报告该终端设备202支持哪一种或几种处理，并且，终端设备202接收网络设备201发送的用于指示终端设备202使用哪种处理的信息。由此，终端设备可以根据网络设备的指示进行相应的处理。
在至少一个实施例中，终端设备202可以使用第二配置许可对未发送的媒体接入控制协议数据单元(MAC PDU)进行发送，如果无法找到合适的第二配置许可，终 端设备202进行下述处理中的至少一者：
终端设备清除第一配置许可的混合自动重传(HARQ)进程的缓存，或者，终端设备清除第一配置许可的HARQ进程中有未发送的媒体接入控制协议数据单元(MAC PDU)的混合自动重传请求(HARQ)进程的缓存；向网络设备201发送指示信息，该指示信息用于指示媒体接入控制协议数据单元(MAC PDU)未发送；终端设备202使用第一配置许可发送未发送的媒体接入控制协议数据单元(MAC PDU)。
在至少一个实施例中，终端设备202可以根据第二配置相对于第一配置改变的情况，进行不同的处理。
例如，在第二配置的传输块大小相对于第一配置的传输块大小(TB size)发生改变时：终端设备使用第一配置许可发送媒体接入控制协议数据单元(MAC PDU)；或者，终端设备清除第一配置许可的混合自动重传(HARQ)进程的缓存，或者，终端设备清除第一配置许可的HARQ进程中有未发送的媒体接入控制协议数据单元(MAC PDU)的混合自动重传请求(HARQ)进程的缓存。
又例如，在第二配置不支持未发送的MAC PDU使用的混合自动重传(HARQ)进程时，终端设备使用第二配置许可(CG)对未发送的媒体接入控制协议数据单元(MAC PDU)进行发送。
再例如，在第二配置的物理层优先级相对于第一配置的物理层优先级发生改变时，终端设备202使用第一配置许可对未发送的媒体接入控制协议数据单元(MAC PDU)进行发送，或者，向网络设备201发送指示信息，指示信息用于指示未发送媒体接入控制协议数据单元。
在本申请实施例的第一方面中，在根据第一CG的第一配置生成MAC PDU但没有在该第一CG上发送该MAC PDU的情况下，进行与未发送的该MAC PDU相关的处理，由此，能够避免该未发送的MAC PDU阻碍后续新数据的传输，保证了数据传输的可靠性。
实施例的第二方面
本申请实施例的第二方面涉及一种接收数据的方法，应用于网络设备，例如网络设备201。
图21是本申请实施例的第二方面的接收数据的方法的一个示意图，如图21所示，该接收数据的方法可以包括：

在本实施例的第二方面中，终端设备具有根据第一配置许可(Configure Grant)的第一配置生成的但未发送的媒体接入控制协议数据单元(MAC PDU)。
如图21所示，该接收数据的方法还包括：
操作2103、向终端设备发送第一配置许可的第二配置的激活指示。
第二配置相对于第一配置发生改变，其中，第二配置相对于第一配置的改变包括：配置许可的传输块大小(TB size)的改变，和/或配置许可的配置所支持的混合自动重传(HARQ)进程的改变，和/或配置许可的物理层优先级的改变。
与本申请实施例的第一方面的发送数据的方法中终端设备202的处理1～处理4对应，在本申请实施例的第二方面的接收数据的方法中，网络设备201可以有对应的操作。
在至少一个实施例中，网络设备201可以从终端设备接收指示信息，该指示信息用于指示终端具有根据第一配置许可(Configure Grant)的第一配置生成的未发送的媒体接入控制协议数据单元(MAC PDU)。
例如，在第一配置许可的优先级低于其他许可的优先级而未发送媒体接入控制协议数据单元(MAC PDU)的情况下，网络设备201在第一配置许可的上行资源上接收指示信息。其中，网络设备201可以在未发送的媒体接入控制协议数据单元(MAC PDU)对应的上行资源上接收解调参考信号(DMRS)或接收未发送的媒体接入控制协议数据单元(MAC PDU)的部分上行数据作为指示信息，或者网络设备使用与未发送的媒体接入控制协议数据单元(MAC PDU)相同的混合自动重传(HARQ)进程和第一配置许可(CG)的配置接收指示信息。
又例如，在第一配置许可低于其他许可的优先级而未发送媒体接入控制协议数据单元(MAC PDU)的情况下，网络设备201通过物理上行控制信道(PUCCH)、媒体接入控制层控制元件(MAC CE)或无线资源控制(RRC)信令接收指示信息。其 中，该指示信息中具有第一配置许可的配置标识以及未发送的媒体接入控制协议数据单元(MAC PDU)使用的混合自动重传请求(HARQ)的进程标识(ID)。
又例如，在未发送的媒体接入控制协议数据单元(MAC PDU)是由于执行先听后说(LBT)失败而未发送的情况下，网络设备在第一配置许可的上行资源上接收指示信息。其中，网路设备201在未发送的媒体接入控制协议数据单元(MAC PDU)对应的上行资源上接收解调参考信号(DMRS)或接收媒体接入控制协议数据单元(MAC PDU)的部分上行数据作为指示信息，或者网络设备201根据未发送的媒体接入控制协议数据单元(MAC PDU)使用的混合自动重传(HARQ)进程和第一配置许可(CG)的配置接收指示信息。
又例如，在未发送的媒体接入控制协议数据单元(MAC PDU)是由于执行先听后说(LBT)失败而未发送的情况下，网络设备通过物理上行控制信道(PUCCH)、媒体接入控制层控制元件(MAC CE)或无线资源控制(RRC)信令接收指示信息。其中，该指示信息中具有第一配置许可的配置标识以及未发送的第一配置许可的PDU使用的混合自动重传请求(HARQ)的进程标识(ID)。
网络设备201可以根据接收到的指示信息，调度未发送的媒体接入控制协议数据单元(MAC PDU)的重传。
在至少一个实施例中，网络设备201可以根据第二配置许可对未发送的媒体接入控制协议数据单元(MAC PDU)进行接收。
其中，第二配置许可的传输块大小(TB size)与第一配置许可的传输块大小相同，例如，第二配置许可的调制与编码策略(MCS)参数与第一配置许可的调制与编码策略(MCS)参数相同，第二配置许可的上行资源大小与第一配置许可的上行资源大小相同。此外，未发送的媒体接入控制协议数据单元(MAC PDU)中复用的逻辑信道支持使用第二配置许可；或者，第一配置许可的物理层优先级与第二配置许可的物理层优先级一致；或者，第二配置许可支持未发送的MAC PDU使用的混合自动重传请求(HARQ)进程。
例如，网络设备201向终端设备202发送第二配置的激活指示后，根据第二配置许可接收媒体接入控制协议数据单元(MAC PDU)。此外，网络设备201还接收第二配置的激活的确认。
在至少一个实施例中，网络设备根据第一配置许可接收未发送的媒体接入控制协 议数据单元(MAC PDU)。
例如，网络设备在发送第一配置许可的第二配置的激活指示之后，根据第一配置许可的第一配置接收未传输的媒体接入控制协议数据单元(MAC PDU)，接收终端设备发送的用于指示已收到第二配置的激活指示的配置激活，并且根据第二配置对第一配置许可进行初始化。
又例如，网络设备201在发送第一配置许可的第二配置的激活指示之后，接收终端设备发送的用于指示未收到第二配置的激活指示的激活确认，根据第一配置许可的第一配置接收未传输的媒体接入控制协议数据单元(MAC PDU)，并且接收终端设备发送的用于指示已收到第二配置的激活指示的激活确认，并根据第二配置对第一配置许可进行初始化。
又例如，网络设备201在发送第一配置许可的第二配置的激活指示之后，根据第二配置许可接收未发送的媒体接入控制协议数据单元(MAC PDU)。
在至少一个实施例中，网络设备201可以接收终端设备发送的终端设备支持的处理类型的信息，并且，向终端设备202发送用于指示处理类型的信息。
在至少一个实施例中，网络设备201根据第二配置相对于第一配置的改变的情况，对终端设备指示处理类型。
例如，在第二配置的传输块大小相对于第一配置的输块大小(TB size)发生改变时：网络设备指示终端设备使用第一配置许可发送媒体接入控制协议数据单元(MAC PDU)，或者，指示终端设备清除第一配置许可的混合自动重传(HARQ)进程的缓存，或者，指示终端设备清除第一配置许可的HARQ进程中有未发送的媒体接入控制协议数据单元(MAC PDU)的混合自动重传请求(HARQ)进程的缓存。
又例如，在第二配置不支持未发送的MAC PDU使用的混合自动重传(HARQ)进程时，网络设备指示终端设备使用第二配置许可发送未发送的媒体接入控制协议数据单元(MAC PDU)。
又例如，在第二配置的物理层优先级相对于第一配置的物理层优先级发生改变时，网络设备指示终端设备使用第一配置许可对说书未发送的媒体接入控制协议数据单元(MAC PDU)进行发送，或者，网络设备指示终端设备向网络设备发送指示信息，指示信息用于指示未发送媒体接入控制协议数据单元。
根据本申请实施例的第二方面中，能够避免终端设备中的未发送的MAC PDU阻 碍后续新数据的传输，保证了数据传输的可靠性。
