Abstract

The embodiment of the invention discloses a data sending method, which comprises the following steps that: under the condition that terminal equipment receives uplink authorization sent by network equipment, the terminal equipment sends a data packet to the network equipment, and the data packet comprises physical uplink shared channel (PUSCH) data and buffer status report (BSR) information, wherein the BSR information is used for indicating the data volume of uplink data of a to-be-sent first service existing in the terminal equipment; and when the terminal device sends the data packet, the terminal device determines the duration of a retransmission BSR timer based on the demand of the first service. By means of the method, the time delay requirement of the time delay sensitive service can be ensured.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data sending method and a related device. Background technique [0002] In the existing Enhanced Machine Type Communication (Enhanced Machine Type Communication, eMTC), when the terminal device has uplink data to be sent, it needs to apply for an uplink authorization to the network. The terminal device receives the regular cache status report triggered by the Packet Data Convergence Protocol (PDCP) layer and the Radio Link Control (RLC) layer through the Media Access Control (MAC) layer After a (Buffer Status Report, BSR) request, the terminal device sends BSR information to the network device. When the terminal device receives the uplink authorization sent by the network device in response to the BSR information, the terminal device sends a data packet to the network device, the data packet includes physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) data ...
