A retransmission monitoring control method, device and terminal for data transmission

Abstract

The invention provides a retransmission monitoring control method and apparatus for data transmission and a terminal. The retransmission monitoring control method is applied to a terminal and comprises the following steps: when uplink data is sent to a base station, obtaining a preset total number of retransmission scheduling monitoring positions, a preset evaluation duration of a first evaluation time when the data transmission is started and a preset first adjustment step length of the total number of the retransmission scheduling monitoring positions; obtaining a monitoring result of a retransmission scheduling number on each monitoring position according to the preset total number of the retransmission scheduling monitoring positions in the first evaluation time; and adjusting the total number of the retransmission scheduling monitoring positions according to the monitoring result and the preset first adjustment step length of the total number of the retransmission scheduling monitoring positions so as to control the retransmission monitoring of the data transmission according to the adjusted total number of the retransmission scheduling monitoring positions within a subsequent second evaluation time.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a retransmission monitoring control method, device and terminal for data transmission. Background technique [0002] The LTE (Long Term Evolution, Long Term Evolution) communication system has a flexible data scheduling and transmission mechanism, and data transmission resources need to be dynamically allocated and authorized by the base station. For example figure 1 As shown, in the case that the terminal has not obtained the uplink transmission resource authorization, the uplink data transmission process includes four parts: [0003] 1) The terminal (TX) sends an uplink scheduling request (SR, Schedule Request) to request the base station (RX) to allocate uplink data transmission resources, such as subframe 2; [0004] 2) After receiving the terminal scheduling request, the base station performs an uplink grant (UL Grant) for the terminal in the corresponding su...

Problems solved by technology

[0013] The technical problem to be solved by the present invention is to provide a data transmission retransmission monitoring control method, device and terminal to solve the problem that the total number of agreed retransmission scheduling monitoring positions is the same when the existing terminal uploads data. Whether retransmission scheduling occurs during data transmission needs to be monitored at the same location. This monitoring method will repeatedly wake up the components on the terminal, resulting in high power consumption and power consumption of the terminal.
