This application claims the priority of a Chinese patent application filed with the State Intellectual Property Office of China on October 10, 2018, with application number 201811178807.9, and with the application name "Transmission Control Method and Device," and on August 22, 2018 with China The priority of the Chinese patent application of the State Intellectual Property Office, application number 201810962531.7, and application name "a data transmission method for reducing power consumption" is incorporated herein by reference in its entirety.

Technical field

Background technique

Discontinuous reception (DRX) means that the user equipment (UE) turns on the receiver only in the necessary time to enter the working state in order to receive downlink data and signaling, and closes the receiver to enter the sleep state at other times , Stop receiving downlink data and signaling, DRX is a working mode that saves the power consumption of the UE. DRX is divided into idle state DRX and connected state DRX. Connected state DRX refers to the DRX characteristics when the UE is in the radio resource control (RRC) connection state. The UE monitors the physical downlink control channel (physical downlink control channel (PDCCH)). To implement DRX, that is, when the RRC is connected, the UE will still enter the sleep state periodically. When the base station determines that the UE is in the sleep state, it will not schedule data for the UE in the sleep state.

FIG. 1A is a timing diagram of DRX. The long DRX cycle of DRX includes a wake-up window and a work window. The UE is in a working state in the wake-up window and is in a sleep state in the sleep window. The time interval corresponding to the on-duration timer, the sleep window is the time interval corresponding to the opportunity for DRX. If the UE receives DCI from the base station within the wake-up window, DCI indicates that the transmission data is scheduled, the UE will start an inactivity timer, the inactivity timer corresponds to a time window, and the UE continues to maintain the time window corresponding to the inactivity timer. Working state in order to extend the duration of the wake-up window; however, the duration of the current inactivity timer is fixed, and the duration of the working state of the UE is correspondingly extended, which increases the power consumption of the UE.
