Abstract
Description
本发明涉及信息处理技术领域，尤其涉及一种常规BSR的触发方法、用户设备(UE)及计算机存储介质。The present invention relates to the field of information processing technologies, and in particular, to a method for triggering a conventional BSR, a user equipment (UE), and a computer storage medium.
在现有的MAC协议中，对于BSR的触发条件，具体的对于regular BSR的触发方式，其中一种方式规定如下：当前有新数据的逻辑信道的优先级大于其他任何有数据的逻辑信道，且有新数据的逻辑信道属于一个逻辑信道组，同时其他有数据的任何一个逻辑信道也属于一个逻辑信道组；或者其他任何属于一个逻辑信道组的逻辑信道都没有数据；触发Regular BSR能够触发SR获取网络调度资源，从而使得业务能够快速得到服务。In the existing MAC protocol, for the trigger condition of the BSR, specifically for the triggering mode of the regular BSR, one of the modes is as follows: the logical channel currently having new data has a higher priority than any other logical channel having data, and A logical channel with new data belongs to a logical channel group, and any other logical channel with data also belongs to a logical channel group; or any other logical channel belonging to a logical channel group has no data; triggering a Regular BSR can trigger SR acquisition The network schedules resources so that the service can be quickly serviced.
但是，基于现有BSR触发条件，确切的说是如下regular BSR的触发条件，在CA duplication场景下会有问题：当前有新数据的逻辑信道的优先级大于其他任何有数据的逻辑信道；或者其他任何逻辑信道都没有数据。即当配置了CA duplication的DRB所对应的两个逻辑信道的优先级配置一样时，如果两个RLC实体正在传输复制数据，如果其中一个RLC实体对应的信道条件较差导致数据滞留在RLC层，比如LCH2的数据发生滞留，这时，LCH1来了新数据也不会触发regular BSR，因为LCH2的优先级跟LCH1的优先级一样，不能及时触发regular BSR也就意味着SR不能及时触发，会导致CA duplication需要支持的对时延要求很敏感的业务的时延要求得不到满足。However, based on the existing BSR trigger conditions, specifically the following trigger conditions of the regular BSR, there is a problem in the CA duplication scenario: the logical channel currently having new data has a higher priority than any other logical channel having data; or other There is no data on any logical channel. That is, when the priority configurations of the two logical channels corresponding to the DRB configured with the CA duplication are the same, if the two RLC entities are transmitting the duplicate data, if the channel conditions corresponding to one of the RLC entities are poor, the data is stuck in the RLC layer. For example, the data of LCH2 is stuck. At this time, the new data of LCH1 will not trigger the regular BSR. Because the priority of LCH2 is the same as that of LCH1, the failure to trigger the regular BSR in time means that the SR cannot be triggered in time, which will result in The latency requirements for services that are sensitive to latency requirements that CA duplication needs to support are not met.

实施例一、Embodiment 1
本发明实施例提供了一种常规BSR的触发方法，应用于用户设备UE，所述方法包括：An embodiment of the present invention provides a method for triggering a conventional BSR, which is applied to a user equipment UE, and the method includes:
当第一逻辑信道属于一个逻辑信道组、且所述第一逻辑信道有新数据时，基于预设条件确定是否触发常规BSR；When the first logical channel belongs to a logical channel group, and the first logical channel has new data, determining whether to trigger a regular BSR based on a preset condition;
其中，所述预设条件包括以下至少之一：The preset condition includes at least one of the following:
所述第一逻辑信道的优先级高于或等于其他已有数据的逻辑信道所配置的优先级中的最高优先级；所述已有数据的逻辑信道中的任一个逻辑信道属于一个逻辑信道组；The priority of the first logical channel is higher than or equal to the highest priority among the priorities configured by the logical channels of other existing data; any one of the logical channels of the existing data belongs to a logical channel group ;
除所述第一逻辑信道以外，其他逻辑信道不包含数据，所述其他逻辑信道中的任一个逻辑信道属于一个逻辑信道组。In addition to the first logical channel, other logical channels do not contain data, and any one of the other logical channels belongs to one logical channel group.
其中，所述第一逻辑信道对应于一个配置了复制数据传输功能的非分裂无线承载中的逻辑信道。The first logical channel corresponds to a logical channel in a non-split radio bearer configured with a duplicate data transmission function.
本实施例中，如果某个属于逻辑信道组(LCG)的第一逻辑信道有新数据，且该第一逻辑信道属于配置了复制数据传输功能的非分裂无线承载，那么regular BSR可以基于如下条件触发：In this embodiment, if a certain logical channel belonging to a logical channel group (LCG) has new data, and the first logical channel belongs to a non-split radio bearer configured with a duplicate data transmission function, the regular BSR may be based on the following conditions. trigger:
新数据属于所述第一逻辑信道，所述第一逻辑信道配置的优先级高于或者等于其他已经有数据的逻辑信道所配置的优先级中的最高优先级，所述已有数据的逻辑信道中的任一个逻辑信道属于一个逻辑信道组；也就是说，除了所述第一逻辑信道之外，其他的逻辑信道可以属于一个逻辑信道组，也可以是不同的逻辑信道组，甚至是属于跟第一逻辑信道组相同的逻辑信道组；该逻辑信道组可以与第一逻辑信道的逻辑信道组相同，当然也可以不同。The new data belongs to the first logical channel, and the priority of the first logical channel configuration is higher than or equal to the highest priority among the priorities configured by other logical channels that already have data, and the logical channel of the existing data Any one of the logical channels belongs to a logical channel group; that is to say, in addition to the first logical channel, other logical channels may belong to one logical channel group, or may be different logical channel groups, or even belong to The first logical channel group has the same logical channel group; the logical channel group may be the same as the logical channel group of the first logical channel, and may of course be different.
或者，or,
除所述第一逻辑信道以外，其他逻辑信道不包含数据，所述其他逻辑信道的任何一个逻辑信道属于一个逻辑信道组；也就是说，其他逻辑信道可以分别属于不同的逻辑信道组，或者，其他逻辑信道中存在N个逻辑信道属于相同的逻辑信道组，剩余的逻辑信道数据另一个逻辑信道组；当然，还可以存在其他逻辑信道中有属于相同逻辑信道组的逻辑信道，也可以均属于不同的逻辑信道组。逻辑信道组的个数不应该大于支持的最大逻辑信道组个数。当前该个数为8个。The other logical channels do not include data except for the first logical channel, and any one of the logical channels belongs to one logical channel group; that is, other logical channels may belong to different logical channel groups, or Among the other logical channels, there are N logical channels belonging to the same logical channel group, and the remaining logical channel data is another logical channel group; of course, there may be other logical channels having logical channels belonging to the same logical channel group, or may belong to Different logical channel groups. The number of logical channel groups should not be greater than the maximum number of logical channel groups supported. The current number is 8.
当然，还可以包括另外的预设条件，也就是第一逻辑信道所属的逻辑信道组中，其他任何逻辑信道都没有数据。Of course, another preset condition may be included, that is, in any logical channel group to which the first logical channel belongs, no other logical channel has data.
其他的预设条件本实施例中不再进行穷举。Other preset conditions are not exhaustive in this embodiment.

That is, the first logical channel is the only one of the corresponding data radio bearers or signaling radio bearers.
关于CA duplication，可以参见图1：对于一个配置了duplication功能的无线承载，如果该无线承载为non-split bearer，则该承载能配置成CA duplication。CA duplication有如下特征：一个PDCP实体对应两个RLC实体；PDCP实体复制PDCP PDU，且分别递交到两个RLC实体；两个RLC实体的逻辑信道配置不同的物理载波集合，这样相同的复制数据不会在相同的载波上面传输以提高分集增益；CA duplication可以通过MAC CE来激活或者去激活。For the CA duplication, refer to Figure 1: For a radio bearer configured with duplication, if the radio bearer is a non-split bearer, the bearer can be configured as CA duplication. The CA duplication has the following characteristics: one PDCP entity corresponds to two RLC entities; the PDCP entity replicates PDCP PDUs and respectively delivers to two RLC entities; the logical channels of the two RLC entities are configured with different physical carrier sets, so that the same duplicate data is not Will be transmitted on the same carrier to increase the diversity gain; CA duplication can be activated or deactivated by MAC CE.
配置了CA duplication的数据无线承载(DRB)一般传输对时延和可靠性要求比较高的业务，比如URLLC业务；由于两个逻辑信道分别传输相同的复制数据，网络一般会给两个逻辑信道配置相同的priority，这样能尽量保证数据这在两个逻辑信道传输的速率一致。The data radio bearer (DRB) configured with CA duplication generally transmits services with high latency and reliability requirements, such as URLLC services. Since two logical channels respectively transmit the same replicated data, the network generally configures two logical channels. The same priority, so as to ensure that the data is transmitted at the same rate on both logical channels.
所述触发常规BSR包括采用以下上报格式之一：The triggering the regular BSR includes adopting one of the following reporting formats:
MAC实体采用第一长BSR上报；其中，所述第一长BSR中包含全部有数据待传的逻辑信道组的缓存状态；也就是说，上报long BSR，包含所有有数据待传的逻辑信道组的缓存状态；The MAC entity adopts a first long BSR report, wherein the first long BSR includes a buffer state of all logical channel groups to which data is to be transmitted; that is, the long BSR is reported, and all logical channel groups having data to be transmitted are included. Cache status;
MAC实体采用第二长BSR上报；其中，所述第二长BSR中包含触发常规BSR的第一逻辑信道所属的逻辑信道组的缓存状态；比如，上报long BSR，只包含触发该regular BSR的逻辑信道所属的逻辑信道组的缓存状态；The MAC entity adopts a second long BSR report, where the second long BSR includes a cache state of a logical channel group to which the first logical channel that triggers the regular BSR belongs. For example, reporting a long BSR includes only logic that triggers the regular BSR. The buffer status of the logical channel group to which the channel belongs;
MAC实体采用短BSR上报；其中，所述短BSR中包含触发常规BSR的第一逻辑信道所属的逻辑信道组的缓存状态；比如，上报short BSR，只包含触发该regular BSR的逻辑信道所述的逻辑信道组的缓存状态。The MAC entity uses a short BSR report, where the short BSR includes the cache state of the logical channel group to which the first logical channel that triggers the regular BSR belongs. For example, reporting the short BSR includes only the logical channel that triggers the regular BSR. The cache state of the logical channel group.
另外，关于优先级参数的配置可以为网络侧为终端设备进行配置，比如，如图2所示，包括：In addition, the configuration of the priority parameter may be configured for the terminal device on the network side, for example, as shown in FIG. 2, including:
步骤201：获取网络侧为所述第一逻辑信道配置的优先级参数。Step 201: Acquire a priority parameter configured by the network side for the first logical channel.
步骤202：当第一逻辑信道有新数据时，基于预设条件确定是否触发常规缓冲区状态报告(BSR)。Step 202: When the first logical channel has new data, determine whether to trigger a regular buffer status report (BSR) based on a preset condition.
其中，所述优先级priority是指网络给所述逻辑信道配置的一个参数，取值按照现有协议为1到16的任意整数；The priority priority refers to a parameter configured by the network to the logical channel, and the value is an integer of 1 to 16 according to the existing protocol.
本实施例的一种具体处理方案，参见图3，有三个无线承载，RB1，2，3；RB1配置了CA duplication，RB2和RB3没有配置duplication；对应的逻辑信道分别为，RB1对应LCH1和LCH2，RB2对应LCH3，RB3对应LCH4。逻辑信道配置的优先级为{8,8,6,4}；且逻辑信道都有相应的LCG。For a specific processing scheme of this embodiment, referring to FIG. 3, there are three radio bearers, RB1, 2, and 3; RB1 is configured with CA duplication, and RB2 and RB3 are not configured with duplication; corresponding logical channels are respectively, and RB1 corresponds to LCH1 and LCH2 respectively. RB2 corresponds to LCH3, and RB3 corresponds to LCH4. The priority of the logical channel configuration is {8, 8, 6, 4}; and the logical channels have corresponding LCGs.
当LCH1有新数据到来，即使LCH1和LCH2的优先级一样，同时LCH2如果有待传数据，也触发regular BSR；When LCH1 has new data, even if LCH1 and LCH2 have the same priority, LCH2 triggers regular BSR if there is data to be transmitted.
当LCH2有新数据到来，即使LCH2和LCH1的优先级一样，同时LCH1如果有待传数据，也触发regular BSR；When LCH2 has new data, even if LCH2 and LCH1 have the same priority, LCH1 triggers regular BSR if there is data to be transmitted.
当LCH3有新数据到来，因为LCH3优先级低于LCH1和LCH2，不触发regular BSR。When LCH3 has new data coming in, because LCH3 has lower priority than LCH1 and LCH2, the regular BSR is not triggered.
可见，通过采用上述方案，就能够在存在新数据的第一逻辑信道的优先级与其他逻辑信道的优先级一致时也能及时触发常规BSR，如此，保证配置了CA duplication的无线承载所传输的数据的时延。It can be seen that, by using the foregoing solution, the regular BSR can be triggered in time when the priority of the first logical channel with the new data is consistent with the priorities of the other logical channels, so that the radio bearer configured with the CA duplication is transmitted. The delay of the data.
