Embodiment Construction

[0041] The embodiments disclosed herein relate to a method for a user equipment (UE) to report a BSR and an apparatus for implementing the method in wireless communication.

[0042] For reference and clarity, here is a brief explanation and description of the various abbreviations and abbreviations used in the text:

[0043] BSR (Buffer Status Reporting) buffer status reporting

[0044] BO (Buffer Occupy) cache occupancy

[0045] LCG (Logical Channel Group) logical channel group

[0046] PayloadSize: The data payload that the MAC can carry.

[0047] The BO Size of the data to be sent refers to the total size of all data that can be multiplexed with the highest priority RB (Radio Bearer, radio bearer).

[0048]The UE determines which BSR Control Element to use according to the comparison result of the PayloadSize, the data size of the short buffer state MAC control element (shortBSR Size) and the data size of the long buffer state MAC control element (long BSR Size).

Abstract

The invention discloses a method for reporting cached state, comprising the steps of determining a logical channel group (LCG) with highest priority and an LCG which is in multiplexing relationship with the LCG with the highest priority through user equipment, and sending predetermined cached state information to a network side, wherein the information at least contains marks of the LCG with the highest priority and the LCG which is in multiplexing relationship with the LCG with the highest priority and information which is used for indicating the size of the cached data of the LCG with the highest priority and the LCG which is in multiplexing relationship with the LCG with the highest priority. The invention also discloses a device for reporting the cached state and the user equipment comprising the device. The new cached state information provided by the embodiment of the invention enables the network side to sufficiently know the current BO status of UE so as to accurately dispatch and improves the efficiency of space resources.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, to a method and device for buffer status reporting (Buffer status Reporting, BSR). Background technique [0002] According to the consensus reached at the 3rd Generation partnership project (3GPP) meeting, uplink scheduling is "Per UE Grant", that is, for uplink scheduling, the evolved Node B (E-Node B, eNB) is based on user The current buffer occupancy (Buffer Occupy, BO) status of the device (UE) and the air interface quality status allocate resources to the UE, and the UE performs internal reprocessing based on the currently allocated resources and the quality of service (Quality of Service, QoS) attribute of the existing service. use. [0003] In order to effectively support uplink scheduling, the UE must report the current BO status to the eNB. For this reason, 3GPP defines two formats of BSR Control Elements (BSR Control Elements) to carry the cu...
