Embodiment 1

[0079] The terminal establishes a connection with cell 1. Due to the increase in traffic, base station 1 adds cell 3 to the terminal according to the measurement report, and configures two data radio bearers, namely data radio bearer 1 and data radio bearer 2, both of which belong to LCG0. Data radio bearer 2 is a radio bearer that can be split and sent, that is, it can be sent by base station 1 and base station 2 respectively.

[0080] Behavior of the terminal:

[0081] Step 1. When the terminal needs to send uplink data, calculate the buffered data size of all current LCGs (currently only LCG0) of each base station.

[0082] Because there is only LCG0, the short BSR is used to report, and there are two wireless data bearers on LCG0, so they can be calculated together.

[0083] Step 2. The terminal determines that there is a split bearer according to the configuration information, and therefore needs to report the size information of the additional buffered data.

[0084] T...

Embodiment 2

[0097] The terminal establishes a connection with cell 1. Due to the increase in traffic, base station 1 adds cell 3 to the terminal according to the measurement report. Two data radio bearers are configured, namely data radio bearer 1 and data radio bearer 2. Data radio bearer 1 belongs to LCG0, data radio bearer 2 belongs to LCG1, wherein data radio bearer 2 is a radio bearer that can be split and sent, that is, it can be sent by base station 1 and base station 2 respectively.

[0098] Behavior of the terminal:

[0099] Step 20, when the terminal needs to send uplink data, calculate the buffered data size of all current LCGs (currently LCG0 and LCG1) of each base station.

[0100] Base station 1 has two LCGs, so the long BSR is used for reporting, and base station 2 has one LCG, so the short BSR is used for reporting.

[0101] Step 21, the terminal judges that there is a split bearer according to the configuration information, and therefore needs to report additional BS inf...

Embodiment 3

[0119] The terminal establishes a connection with cell 1. Due to the increase in traffic, base station 1 adds cell 3 to the terminal according to the measurement report, and configures two data radio bearers, namely data radio bearer 1 and data radio bearer 2, both of which belong to LCG0. Data radio bearer 2 is a radio bearer that can be split and sent, that is, it can be sent by base station 1 and base station 2 respectively.

[0120] Behavior of the terminal:

[0121] Step 40, when the terminal needs to send uplink data, calculate the buffered data size of all current LCGs (currently only LCG0) of each base station.

[0122] Because there is only LCG0, the short BSR is used to report, and there are two wireless data bearers on LCG0, so they can be calculated together.

[0123] Step 41, the terminal receives a notification from the base station 1 and learns that it needs to report additional buffered data size information, that is, the buffered data size information of the ...

Abstract

Proposed are a method and device for reporting and receiving a buffer status. The method comprises: when a terminal judges that there is a split bearer or receives a notification which is sent by a base station and is required to report an additional buffer report, sending, by the terminal, a buffer status report (BSR) of a radio bearer to the base station; wherein the BSR carries size information about the buffer data of the radio bearer and size information about additional buffer data. The embodiments of the present invention realize reporting a buffer status when there is a split bearer.

Description

technical field [0001] The invention relates to the field of wireless bearer technology, in particular to a method and device for reporting and receiving buffer status. Background technique [0002] In the Long Term Evolution (LTE, Long Term Evolution) system, the protocol architecture of the user plane on the terminal side includes the following protocol layers from bottom to top: [0003] The physical (PHY, Physical) layer mainly transmits information to the media access control (MAC, Media Access Control) layer or higher layers through the transmission channel; [0004] The MAC layer mainly provides data transmission and wireless resource allocation through logical channels, and completes hybrid automatic repeat request (HARQ, Hybrid ARQ), scheduling (SCH, Scheduling), priority processing, and multiplexing and demultiplexing (MUX, Multiplexing) and other functions; [0005] The radio link control (RLC, Radio Link Control) layer mainly provides segmentation and retransmi...
