Problems solved by technology

The base station may receive different BSRs from different component carriers within a subframe, which may easily cause misunderstandings by the base station and may not be able to allocate resources reasonably

Embodiment Construction

[0024] In the case of carrier aggregation, the embodiment of the present invention only reports the BSR on one component carrier, that is, only one BSR is reported, which realizes the reporting of buffer status in the case of carrier aggregation and avoids misunderstanding of the base station.

[0025] see figure 1 In this embodiment, the main method flow of reporting the buffer status report in the carrier aggregation communication system is as follows:

[0026] Step 101: The UE judges and determines that the trigger condition for reporting the BSR has been met.

[0027] Step 102: UE obtains cache status.

[0028] Step 103: the UE determines a component carrier from multiple component carriers, and reports a buffer status report (BSR) through the determined component carrier. Specifically, the UE determines a component carrier capable of bearing the BSR from multiple component carriers, which may be any component carrier capable of bearing the BSR. If all the component car...

Abstract

The invention discloses a method for reporting a buffer status report, which is used for reporting a buffer status under the condition of carrier wave aggregation and comprises the steps that: UE (User Equipment) judges whether a triggering condition of reporting the BSR (Buffer Status Report) is satisfied or not in a communication system adopting a carrier wave aggregation technology; the buffer status is obtained by the UE under the condition that UE confirms that the triggering condition of reporting the BSR is satisfied; and UE determines a member carrier wave from a plurality of member carrier waves and reports the BSR by the determined member carrier wave. The invention also discloses a device used for realizing the method.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for reporting a cache status report. Background technique [0002] Compared with the LTE system, the peak rate of the upgraded Long Term Evolution (LTE Advanced, LTE-A) system is greatly improved. In order to meet this point, the LTE-A system introduces a carrier aggregation (CarrierAggregation, CA) technology. The carrier aggregation technology refers to the uplink and downlink of a cell including multiple component carriers (Component Carrier, CC), instead of only one set of carriers in LTE and previous wireless communication systems. [0003] From the perspective of a user equipment (UE), a UE can simultaneously receive downlink data and scheduling information on multiple downlink component carriers, and can also send uplink data and feedback to downlink data on multiple uplink component carriers. [0004] In addition, uplink data transmission is scheduled by t...
