Embodiment 1

[0060] In this embodiment, the base station selects a preset mapping table of service priority and logical channel group identifier according to the cell identifier of the user equipment UE performing the method. That is to say, in this embodiment, all user equipment UEs belonging to the same cell under the base station (that is, corresponding to the same cell ID under the base station) all have the same mapping table of service priority and logical channel group ID, and User equipment UEs in different cells may have different mapping tables between service priorities and logical channel group identifiers. The base station sends the mapping table of the service priority and the logical channel group identifier to the user equipment UE in each cell by broadcasting or by using a radio resource control RRC message.

[0061] For example, as shown in Table 1, Table 1 shows the mapping table of service priority PPP and LCG respectively corresponding to cell A and cell B in an applic...

Embodiment 2

[0068] In this embodiment, the base station selects a preset mapping table of service priority and logical channel group identifier according to the cell identifier of the user equipment UE performing the method. That is to say, in this embodiment, each user equipment UE belonging to the base station may have a different mapping table of service priority and logical channel group identifier, and different user equipment UE may have different service priority and logical channel group identifier mapping table. Mapping table of channel group IDs. The base station may send the mapping table of service priorities and logical channel group identifiers to one or some user equipment UEs through a radio resource control RRC message. The advantage of this method is that when the identity of the user equipment UE is very important, it can ensure that its communication needs are always responded to first. It can be realized by adding a special identity to the subscription data of the use...

Embodiment 3

[0076] In this embodiment, the base station selects a preset mapping table between service priorities and logical channel group identifiers according to the target group identifier for executing the method. That is to say, in this embodiment, as long as the communication processes belonging to different target group IDs may have different mapping tables of service priorities and logical channel group IDs, no matter which source UE initiates the D2D service. The base station may send the mapping table of the service priority and the logical channel group identifier to a certain or some target groups by broadcasting or a radio resource control RRC message. The advantage of this method is that for some public safety scenarios, no matter who is the source UE that initiates the service, if the target group at the communication peer represents a specific group, such as the emergency team, it can The priority is to get a response so that the user holding the source UE has a higher ch...

Abstract

An embodiment of the invention discloses a sidelink buffer status report generation method. The method comprises the steps of uploading a terminal identification and / or a target group identification to a base station, and receiving service priorities sent from the base station and a mapping table of logic channel bank identifications, wherein the mapping table is corresponding to the terminal identification and / or target group identification, and a cell identification corresponding to the terminal identification; acquiring the target group identification, and acquiring the sizes and service types of buffer data packages sent to the target group identification and service priority of each service type; seeking, according to the mapping table, the logic channel bank identification corresponding to the service priority of the buffer data package sent to the target group identification; and generating the sidelink buffer status report according to the size of the buffer data package sent to the target group identification and the found logic channel bank identification. The invention also discloses a sidelink buffer status report generation device. Through adoption of the sidelink buffer status report generation method and device, the resource utilization rate can be improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for generating a secondary link buffer status report. Background technique [0002] Device-to-Device (English: Device to Device, D2D for short) is currently one of the hot topics in the discussion of standardization technologies of the 3GPP (Chinese: 3rd Generation Partnership Project, English: the 3rd Generation Partnership Project). D2D communication is a point-to-multipoint group communication (Group Communication) process. [0003] Such as figure 1 , figure 1 The D2D group communication process based on base station scheduling mode is shown. A typical group is composed of a source user equipment UE (English: UserEquipment) and several target UEs. The communication of the same source UE for different groups is uniquely distinguished by the destination group ID (DestinationGroupID), and the destination group ID is It is obtained by forming a targe...
