Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] see image 3 , which is a schematic flow chart of the BSR triggering method provided by the embodiment of the present invention, the D2D Padding BSR triggering process may include:

[0029] Step 31: The terminal determines the Padding resource size when organizing the D2N MAC PDU. Wherein, the Padding resource is the remaining resource after subtracting the resource occupied by the D2N data and control information that the terminal...

Abstract

The embodiment of the present invention discloses a buffer state reporting BSR triggering method and device, which relate to the field of wireless communication and are used to solve the problem that there is no D2D Padding BSR triggering mechanism in the prior art. In the embodiment of the present invention, the terminal determines the size of the Padding resource when organizing the D2N MAC PDU; according to the size of the Padding resource and the priority of the D2D Padding BSR MAC CE, it decides whether to trigger the D2D Padding BSR, thereby realizing the D2D Padding BSR trigger mechanism.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a buffer state reporting BSR triggering method and device. Background technique [0002] In the future development of mobile communication systems, in order to better meet user needs and improve the efficiency of information interaction between devices, D2D Discovery (Device to Device Discovery, device to device discovery) and D2D Communication (Device to Device Communication, device to device communication) are introduced. device communication) mechanism. [0003] In the LTE (Long Term Evolution, long-term evolution) system, the communication adopts the centralized network control method, that is, the D2N (Device to Network, device to network) transmission method, figure 1 A system architecture diagram of the D2N transmission mode is shown. Such as figure 1 As shown, the uplink and downlink data of UE (User's Equipment, user equipment, that is, terminal) is sent and rece...
