Problems solved by technology

Since the BSR is in the triggered state, it will still be sent, but since the PDCP SDU and the corresponding PDCP PDU that triggered the BSR have been discarded, it is unnecessary to send the BSR at this time, so unnecessary routines will be caused in this case. BSR sent, wasting transmission resources

Abstract

The invention discloses a transmitting method for a BSR (Buffer Status Report). The transmitting method comprises the following steps of: if an LCG (Logical Channel Group) logical channel meets trigger conditions of a conventional BSR, triggering a first conventional BSR; or if a BSR retransmission timer is overtime and transmittable data exist in the LCG logical channel, triggering a second conventional BSR; if the LCG logical channel triggering the first conventional BSR meets non-transmittable conditions, canceling the first conventional BSR; or if the second conventional BSR is triggered, all LCG logical channels meet the non-transmittable conditions, canceling the second conventional BSR; and if uplink transmission resources exist on the current TTI (Transmission Time Interval) and the first or second conventional BSR which is triggered and not canceled exist, transmitting a BSR MAC CE (Buffer Status Report Media Access Control Control Equipment) by using the uplink transmission resources. According to the transmitting method disclosed by the invention, the forming and reporting of the BSR MAC CE having no significance in the UE is avoided, and thus transmission resources are saved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for sending data, a method and a device for allocating transmission resources. Background technique [0002] In the existing Long Term Evolution (LTE for short) system, all user equipment (User Equipment, UE for short) that have established a connection with an evolved base station (evolved NodeB, eNB for short) share air interface resources, that is, the eNB transmits The Transmission Time Interval (TTI for short) dynamically allocates transmission resources to its subordinate UEs according to information such as the amount of data of the UE, thereby improving channel utilization. [0003] In the uplink data scheduling, the UE reports its buffered data volume to the eNB by sending a buffer status report (Buffer Status Report, BSR for short), so as to provide reference information for the uplink scheduling of the eNB. The eNB allocates uplink transmission r...
