Embodiment 1

[0153] see Figure 4 , Embodiment 1 of the present invention provides a method for obtaining a buffer state, which is applied to a network side device, and includes the following steps:

[0154] S101. Group at least one bearer and / or logical channel corresponding to the terminal to obtain at least one primary group;

[0155] S102. Group each primary group in the at least one primary group to obtain at least one secondary group;

[0156] S103. Determine a first mapping relationship, that is, determine a first mapping relationship between each bearer and / or logical channel in each of the at least one secondary group and the at least one secondary group;

[0157] S104. Send the first mapping relationship to the terminal;

[0158] S105. Receive a first message representing a buffer state of the terminal reported by the terminal to the network side device based on the first mapping relationship;

[0159] S106. Obtain the buffer state of the terminal based on the first message. ...

Embodiment 2

[0171] see Figure 5 , Embodiment 1 of the present invention provides a network side device, including:

[0172] The first grouping module 101 is configured to group at least one bearer and / or logical channel corresponding to the terminal to obtain at least one primary group;

[0173] The second grouping module 102 is configured to group each primary group in the at least one primary group to obtain at least one secondary group;

[0174] The first determining module 103 is configured to determine a first mapping relationship, that is, to determine each bearer and / or logical channel in each of the at least one secondary group and the first mapping relationship of the at least one secondary group a mapping relationship;

[0175] The first sending module 104 is configured to send the first mapping relationship to the terminal;

[0176] The first receiving module 105 is configured to receive a first message representing a buffer state of the terminal reported by the terminal to...

Embodiment 3

[0191] see Image 6 , the third real-time example of the present invention provides a method for reporting buffer status, which is applied to a terminal and includes the following steps:

[0192] S201. Receive a first mapping relationship sent by a network side device for representing a correspondence relationship between at least one bearer and / or logical channel and at least one logical channel group LCG;

[0193] S202, judging whether the buffer state satisfies the trigger condition for reporting the buffer state to the BSR;

[0194] S203. If satisfied, report a first message for representing the buffer state to the network side device based on the first mapping relationship.

[0195] Wherein the first mapping relationship in the step S201 is specifically:

[0196] The network side device obtains at least one primary group by grouping at least one bearer and / or logical channel corresponding to the terminal, and each primary group in the at least one primary group includes...

Abstract

The invention discloses a method for obtaining the buffer status, a method for reporting the buffer status, network side equipment and a terminal. The network side equipment determines a mapping relation between different loads and / or logic channels and logic channel groups (LCG) and sends the mapping relation to the terminal, the terminal conducts triggering judgment on buffer status report (BSR), and when it is judged that BSR is triggered, buffer status report (BSR) is conducted on the configuration of the terminal according to the network side equipment. Accordingly, the technical problemof how to conduct buffer status report when the numerology and / or TTI corresponding to different loads and / or logic channels are different or in the scene that multiple numerology and / or TTI coexist in the prior art is solved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for obtaining and reporting buffer state, network side equipment and a terminal. Background technique [0002] 1. The BSR (Buffer Status Report) mechanism of the LTE system [0003] The LTE system is a scheduling-based system. The base station allocates time-frequency resources required for data transmission to the terminal equipment, and the terminal performs downlink data reception or uplink data transmission according to the scheduling command of the base station. Uplink data transmission is scheduled by the base station, and the base station scheduler will notify the terminal through an UL grant (uplink scheduling grant) after determining the allocation of uplink resources. The basis for the base station scheduler to allocate uplink resources is the amount of uplink data to be sent by the terminal, that is, the buffer status of the terminal. The cache is on the terminal s...
