本申请涉及通信领域，特别涉及一种生成缓存状态报告的方法、确定缓存状态报告的方法及其装置、通信系统。

在无线通信系统中，当终端设备的缓存中有待发送数据时，会发送缓存状态报告(Buffer Status Report，BSR)，用于报告在该终端设备的上行的缓冲区里有多少数据需要发送。其中，缓存状态报告可以分为：长的缓存状态报告(Long BSR)，截断的缓存状态报告(Truncated BSR)，以及短的缓存状态报告(Short BSR)。
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
在现有技术中，长的缓存状态报告(Long BSR)和截断的缓存状态报告(Truncated BSR)可以采用相同的BSR数据格式。图1是现有的BSR数据格式的一个示意图，如图1所示，现有的BSR数据格式包括一个比特映射字段101和一个或多个缓存大小(Buffer Size)字段102，其中，缓存大小字段102中包含逻辑信道组(LCG)的缓存大小。
对于Long BSR，比特映射字段101的每个比特指示每个逻辑信道组(Logical Channel Group，LCG)的缓存大小是否包含在该BSR中。对于Truncated BSR，比特映射字段101的每个比特指示每个LCG是否具有待发送的数据，不指示该LCG的缓存大小是否包含在该BSR中。
本申请的发明人发现，在现有技术中，当网络设备收到Truncated BSR后，无法判断哪些LCG的缓存大小包含在该BSR中，即，无法确定BSR中的每个缓存大小字段102与LCG的对应关系。

根据本申请实施例的第二方面，提供了一种确定缓存状态报告的装置，包括：
第四确定单元，其根据逻辑信道组(LCG)相关的优先级信息确定目标逻辑信道组；以及

实施例1
本申请实施例1提供一种生成缓存状态报告的方法，该方法由终端设备执行。
图3是本实施例的生成缓存状态报告的方法的一个示意图，如图3所示，该方法包括：
步骤301、终端设备根据逻辑信道组(Logical Channel Group，LCG)相关的优先级信息确定目标逻辑信道组；
步骤302、该终端设备生成缓存状态报告(Buffer Status Report，BSR)，所述缓存状态报告包含该目标逻辑信道组的缓存大小(Buffer Size)。
根据本实施例，终端设备能够根据LCG相关的优先级信息确定目标逻辑信道组并在BSR中包含该目标逻辑信道组的缓存大小，由此，能够明确目标逻辑信道组与BSR中包含的缓存大小之间的对应关系，便于终端设备和网络设备采用一致的、且明确的技术方案来确定目标逻辑信道组与BSR中包含的缓存大小之间的对应关系。
在本实施例中，该终端设备生成该缓存状态报告可以是截断的缓存状态报告(Truncated BSR)。由此，在本实施例中，对于Truncated BSR，能够根据LCG相关的优先级信息，明确目标逻辑信道组与该Truncated BSR中包含的缓存大小之间的对应关系，便于终端设备和网络设备采用一致的、且明确的技术方案来确定目标逻辑信道组与Truncated BSR中包含的缓存大小之间的对应关系。
与之相对，在现有的通信标准中，针对Truncated BSR，网络设备仍然难以根据明确的技术方案来判断哪些LCG的缓存大小包含在该Truncated BSR中。
在本实施例中，该截断的缓存状态报告例如可以是长的截断的缓存状态报告(Long Truncated BSR)，或短的截断的缓存状态报告(Short Truncated BSR)，关于长的截断的缓存状态报告和短的截断的缓存状态报告的含义，可以参考新空口(New Radio，NR)技术中的定义。
此外，在本实施例中，该终端设备生成的该缓存状态报告也可以是长的缓存状态报告(Long BSR)或短的缓存状态报告(Short BSR)，由此，对于Long BSR或Short BSR，也能够根据LCG相关的优先级信息，明确目标逻辑信道组与该BSR中包含的缓存大小之间的对应关系。
在本实施例中，步骤301的逻辑信道组可以是具有待发送数据的逻辑信道组。由此，该终端设备所确定的目标逻辑信道组都是具有待发送数据的逻辑信道组。
根据一个具体实施方式，在步骤301中，该终端设备可以根据所有逻辑信道组相关的优先级信息对所有逻辑信道组进行排序，再根据该缓存状态报告的最大允许包含的逻辑信道组的缓存大小的数目，从排序后的所有逻辑信道组中挑选具有待发送数据的逻辑信道组，作为目标逻辑信道组，例如，该缓存状态报告的最大允许包含的逻辑信道组的缓存大小的数目为5，那么在步骤301中所确定的目标逻辑信道组的数目也是5。
根据另一个具体实施方式，在步骤301中，该终端设备可以也先从所有的逻辑信道组中挑选出具有待发送数据的逻辑信道组，根据具有待发送数据的逻辑信道组相关的优先级信息对这些具有待发送数据的逻辑信道组进行排序，再根据该缓存状态报告的最大允许包含的逻辑信道组的缓存大小的数目，从排序后的具有待发送数据的逻辑信道组中挑选出逻辑信道组，作为目标逻辑信道组。
在本实施例中，该缓存状态报告的最大允许包含的逻辑信道组的缓存大小的数目可以由媒体接入控制层协议数据单元(MAC PDU)的剩余比特数目或填充比特数目决定，原因在于，当该缓存状态报告为截断的缓存状态报告时，该截断的缓存状态报告通过MAC PDU的剩余比特或填充比特来传送，因此，该截断的缓存状态报告所能包含的最大数量的逻辑信道组的缓存大小受到MAC PDU的剩余比特数目或填充比特数目限制，即，该截断的缓存状态报告的最大允许包含的逻辑信道组的缓存大小的 数目由MAC PDU的剩余比特数目或填充比特数目决定。
在本实施例的步骤302中，该终端设备可以按照逻辑信道组相关的优先级信息从高到低的顺序在缓存状态报告中包含目标逻辑信道组的缓存大小。其中，当两个以上的逻辑信道组具有相同优先级信息的情况，该终端设备可以根据逻辑信道组标识(LCG ID)确定该具有相同优先级信息的逻辑信道组的排序，例如，终端设备可以根据逻辑信道组标识(LCG ID)的升序或降序确定该具有相同优先级信息的逻辑信道组的排序。
在本实施例中，该终端设备在缓存状态报告中包含的缓存大小的数目可以由该缓存状态报告的最大允许包含的逻辑信道组的缓存大小的数目决定，即，该终端设备可以按照上述的顺序在缓存状态报告中包含目标逻辑信道组的缓存大小，直到缓存状态报告中包含的缓存大小的数目达到该缓存状态报告的最大允许包含的逻辑信道组的缓存大小的数目。
例如，终端设备生成长的截断的BSR，该长的截断的BSR包含具有待发送数据的逻辑信道组的缓存大小，其中，这些缓存大小按照各逻辑信道组相关的优先级信息的降序方式，被先后包含在该BSR中，直到达到最大允许包含的LCG的缓存大小的数目；其中，当两个以上的逻辑信道组的优先级信息相同时，可以按照各逻辑信道组的LCG ID的升序或降序方式对该两个以上的逻辑信道组排序。
在本实施例中，逻辑信道组(LCG)相关的优先级信息例如可以是逻辑信道组的优先级等信息。
如图3所示，在本实施例中，该方法还可以具有：
步骤303、终端设备确定所述逻辑信道组相关的优先级信息。
在本实施例的步骤303中，可以根据逻辑信道组包含的逻辑信道(Logical Channel，LCH)的逻辑信道优先级(LCH Priority)确定该逻辑信道组相关的优先级信息，例如，该终端设备可以将该逻辑信道组包含的特定的逻辑信道(Logical Channel，LCH)的逻辑信道优先级(LCH Priority)作为该逻辑信道组相关的优先级信息，并根据该逻辑信道组相关的优先级信息来确定目标逻辑信道，并生成包含该目标逻辑信道组的缓存大小(Buffer Size)的缓存状态报告，其中，该逻辑信道组包含的特定的逻辑信道(Logical Channel，LCH)例如可以是：该逻辑信道组包含的逻辑信道中或具有待发送数据的逻辑信道中具有最高逻辑信道优先级的逻辑信道，或具有 最低逻辑信道优先级的逻辑信道，或具有第N高逻辑信道优先级的逻辑信道，或具有第M低逻辑信道优先级的逻辑信道，其中，N和M均为小于该逻辑信道组中逻辑信道总数目的自然数。
在一个具体实施方式中，逻辑信道组相关的优先级信息是该逻辑信道组包含的逻辑信道中具有最高逻辑信道优先级的逻辑信道的优先级，由此，可以根据逻辑信道组中的最高逻辑信道优先级确定该逻辑信道组相关的优先级信息，其有益效果在于：可以优先上报那些具有更高逻辑信道优先级的逻辑信道的缓存信息，相应的，具有越高LCH优先级的LCG也应该优先上报，有助于更早反映高优先级业务的缓存情况。
例如，终端设备生成长的截断的BSR，该长的截断的BSR包含具有待发送数据的逻辑信道组(即，目标逻辑信道组)的缓存大小，其中，这些缓存大小按照各逻辑信道组包含的逻辑信道中具有最高逻辑信道优先级的LCH的优先级的降序方式，被先后包含在该BSR中，直到达到最大允许包含的LCG的缓存大小的数目；其中，当两个以上的逻辑信道组的优先级信息相同时，可以按照各逻辑信道组的LCG ID的升序或降序方式对该两个以上的逻辑信道组排序。
在另一个具体实施方式中，该逻辑信道组相关的优先级信息是该逻辑信道组包含的逻辑信道中具有最低逻辑信道优先级的逻辑信道的优先级，由此，可以根据逻辑信道组中的最低逻辑信道优先级确定该逻辑信道组相关的优先级信息，其有益效果在于：可以优先上报包含的LCH优先级都很高的LCG的缓存状态信息，有助于尽早反映更多的具有较高优先级业务的缓存情况。

实施例8
本申请实施例8提供一种发送缓存状态报告的方法，该方法由终端设备执行。
图9是本实施例的发送缓存状态报告的方法的一个示意图，如图9所示，该方法包括：
步骤901、终端设备发送缓存状态报告。
图10是本实施例的缓存状态报告的一个数据格式示意图。如图10所示，缓存状态报告(BSR)1000可以包括：逻辑信道组标识(LCG ID)字段1001和缓存大小字段1002。
在本实施例中，逻辑信道组标识(LCG ID)字段1001可以包含逻辑信道组标识(LCG ID)；缓存大小字段1002可以包含该逻辑信道组标识(LCG ID)对应的逻辑信道组的缓存大小(Buffer Size)。
根据本实施例，终端设备发送的缓存状态报告能够指示该缓存状态报告中包含的缓存大小与逻辑信道组之间的对应关系，便于终端设备和网络设备采用一致的、且明确的技术方案来确定逻辑信道组与BSR中包含的缓存大小之间的对应关系。
在本实施例中，如图10所示，在缓存状态报告(BSR)1000中，每个逻辑信道组标识(LCG ID)字段1001可以为3比特，每个缓存大小字段1002可以为5比特；此外，本实施例可以不限于此，每个逻辑信道组标识(LCG ID)字段1001和每个缓存大小字段1002占用的比特数也可以是其它数值。
在本实施例中，如图10所示，逻辑信道组标识(LCG ID)字段1001和缓存大小字段1002是成对存在的，由此，能够指示缓存大小与逻辑信道组之间的对应关系。如图10所示，缓存状态报告1000中包含的逻辑信道组标识(LCG ID)字段1001和缓存大小字段1002的组合的数目可变。
在本实施例中，终端设备发送的该缓存状态报告可以是长的缓存状态报告(Long BSR)，或短的缓存状态报告(Short BSR)，或长的截断的缓存状态报告(Long Truncated BSR)，或短的截断的缓存状态报告(Short Truncated BSR)等。

在图11中，比特映射字段1103的每个比特可以与一个逻辑信道组对应，并且，该比特可以指示对应的逻辑信道组是否具有待发送的数据，例如，比特映射字段1103中，与逻辑信道组LCG 7、LCG 5、LCG 2、LCG 0对应的比特的数据为1，其他比特的数据为0时，指示出逻辑信道组LCG 7、LCG 5、LCG 2和LCG 0具有待发送的数据，而逻辑信道组LCG 6、LCG 4、LCG 3和LCG 1不具有待发送数据。
在本实施例中，通过设置比特映射字段1103，能够对逻辑信道组标识(LCG ID)字段1101和缓存大小字段1102之外的信息进行补充，例如，终端设备有5个逻辑信道组中有待发送数据，逻辑信道组标识(LCG ID)字段1101和缓存大小字段1102能够指示其中的3个具有待发送数据的逻辑信道组，比特映射字段1103能够指示这5个具有待发送数据的逻辑信道组，由此，对于逻辑信道组标识(LCG ID)字段1101和缓存大小字段1102中无法指示的2个具有待发送数据的逻辑信道组，也能通过比特映射字段1103进行指示。
根据本实施例，终端设备发送的缓存状态报告能够指示该缓存状态报告中包含的缓存大小与逻辑信道组之间的对应关系，便于终端设备和网络设备采用一致的、且明确的技术方案来确定逻辑信道组与BSR中包含的缓存大小之间的对应关系。

实施例15
本申请实施例15提供一种发送缓存状态报告的方法，该方法由终端设备执行。
图17是本实施例的发送缓存状态报告的方法的一个示意图，如图17所示，该方法包括：
步骤1701、终端设备在媒体接入控制层协议数据单元(MAC PDU)的剩余比特或填充比特(padding bits)的数目等于或大于用于上报具有待发送数据的逻辑信道组(LCG)的缓存大小所对应的长的缓存状态报告(Long BSR)加上所述长的缓存状态报告对应的子头长度的情况下，发送所述长的缓存状态报告。
在本实施例中，剩余比特或填充比特的数目并不固定，并且，在具有待发送数据的逻辑信道组的数量发生变化的情况下，用于上报具有待发送数据的逻辑信道组的缓存大小所对应的长的缓存状态报告(Long BSR)的长度也会变化，因此，在本实施例的发送缓存状态报告的方法中，将可变的剩余比特或填充比特的数目而不是一个固定的阈值作为判断依据，来确定是否发送长的缓存状态报告，由此，在长的缓存状态报告的长度变化的场景下，能够合理地确定发送长的缓存状态报告的时机。
而在现有技术中，当BSR的长度达到固定的Long BSR的阈值时，终端设备上报Long BSR，该方式适用于Long BSR长度不可变的场景。而在Long BSR的长度可 变的场景下，例如新空口(New Radio，NR)系统中，利用固定的阈值来判断何时发送Long BSR将会造成误判。
在图17所示的方法中，具有待发送数据的逻辑信道组(LCG)可以是在发送缓存状态报告时该终端设备中所有的具有待发送数据的逻辑信道组(LCG)。
图18是本实施例的发送缓存状态报告的方法的另一个示意图，如图18所示，该方法包括：
步骤1801、终端设备在媒体接入控制层协议数据单元(MAC PDU)的剩余比特或填充比特(padding bits)的数目等于或大于用于上报具有待发送数据的逻辑信道组(LCG)的缓存大小所对应的长的缓存状态报告(Long BSR)加上所述长的缓存状态报告对应的子头长度的情况下，并且，在所述媒体接入控制层协议数据单元的所述剩余比特或填充比特的数目等于或大于短的缓存状态报告(Short BSR)加上所述短的缓存状态报告对应的子头长度的情况下和/或在缓存状态报告发送时有多于1个逻辑信道组具有待发送的数据的情况下，发送所述长的缓存状态报告。
在图18所示的方法中，涉及3个判断条件：
条件1、媒体接入控制层协议数据单元(MAC PDU)的剩余比特或填充比特(padding bits)的数目等于或大于用于上报具有待发送数据的逻辑信道组(LCG)的缓存大小所对应的长的缓存状态报告(Long BSR)加上所述长的缓存状态报告对应的子头长度；
条件2、所述媒体接入控制层协议数据单元(MAC PDU)的所述剩余比特或填充比特的数目等于或大于短的缓存状态报告(Short BSR)加上所述短的缓存状态报告对应的子头长度；
条件3、缓存状态报告发送时有多于1个逻辑信道组具有待发送的数据。
其中，条件1与图17的步骤1701中的条件相同。
根据图18所示的方法，在如下情况下，终端设备可以发送场的缓存状态报告：条件1和条件2都满足的情况下；或者，条件1和条件3都满足的情况下；或者，条件1、条件2和条件3都满足的情况下。
根据本实施例，在长的缓存状态报告的长度变化的场景下，能够合理地确定发送长的缓存状态报告的时机。

在本实施例中，第一发送单元1901还可以结合其它的条件，来判断是否发送长的缓存状态报告，例如，所述第一发送单元在媒体接入控制层协议数据单元(MAC PDU)的剩余比特或填充比特(padding bits)的数目等于或大于用于上报具有待发送数据的逻辑信道组(LCG)的缓存大小所对应的长的缓存状态报告(Long BSR)加上所述长的缓存状态报告对应的子头长度的情况下，并且，在所述媒体接入控制层协议数据单元的所述剩余比特或填充比特的数目等于或大于短的缓存状态报告(Short BSR)加上所述短的缓存状态报告对应的子头长度的情况下和/或在缓存状态报告发送时有多于1个逻辑信道组具有待发送的数据的情况下，发送所述长的缓存状态报告。
