Problems solved by technology

[0004] However, within multiple TTIs between sending out the BSR and receiving the uplink grant from the network side, because the UE is not allocated uplink resources, it cannot send uplink data, resulting in discontinuity in the process of sending uplink data by the UE

Embodiment Construction

[0029] As mentioned above, when the UE has data to send to the network, it will report the amount of data to the network through the BSR. In the prior art, according to the agreement, the situations that can trigger the BSR are as follows:

[0030] 1. When new uplink data arrives on a logical channel of a Logical Channel Group (LCG); and this logical channel has a higher priority than any logical channel with uplink data in any LCG, or this logical channel Other logical channels in the LCG have no uplink data.

[0031] 2. The remaining space in the uplink allocated resource is enough to hold the BSR.

[0032] Specifically, usually when the previous batch of data to be sent is about to be uploaded, for example, when the current upload is the last batch of uploaded data, if the remaining space in the resources allocated for uplink is sufficient to accommodate the BSR, the user terminal can use this BSR is sent together with the first upload to notify the network side of the da...

Abstract

A method and device for reporting a BSR, a storage medium, and a user terminal, the method comprising: sending a first BSR to a network side, the first BSR comprising a data volume of a previous batchof data to be sent; when an uplink authorization instruction is received from the network side each time, judging whether an unsent part in the previous batch of to-be-sent data can be uploaded within a preset duration or not according to an uplink transmission data volume in the uplink authorization instruction; and if the unsent part can be uploaded within a preset time length, sending a secondBSR to the network side together during the uploading, the second BSR comprising the sum of the data volume of the next batch of data to be sent and the data volume of the unsent part. According to the scheme of the invention, the UE can actively judge and timely report the required to-be-sent data volume, the accuracy is improved, and uplink resources can be saved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and device for reporting BSR, a storage medium, and a user terminal. Background technique [0002] In the prior art, uplink data of a user terminal (User Equipment, UE) is often sent intermittently, that is, it cannot be sent rapidly and continuously. [0003] Specifically, when the UE has data to send to the network side, it will report the amount of data to the network side through a buffer status report (Buffer Status Report, BSR). After the network receives the BSR from the UE, it will , after several subsequent transmission time intervals (Transmission Time Interval, TTI), the UE is authorized to allocate uplink resources, and the UE must send data according to the uplink resources indicated by the received authorization information. [0004] However, within multiple TTIs between sending the BSR and receiving the uplink grant from the network s...
