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 invention discloses a method and device for triggering BSR and relates to the field of wireless communication. The method and device for triggering BSR are used for solving the problem that no D2D Padding BSR triggering mechanism exists in the prior art. According to the method and device for triggering BSR, when organizing D2N MAC PDU, a terminal determines the size of a Padding resource; according to the size of the Padding resource and the priority of D2D Padding BSR MAC CE, whether D2D Padding BSR is triggered or not is judged, and then the D2D Padding BSR triggering mechanism is achieved.

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). [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 received under the control of eNodeB (evolve NodeB, ...
