Description

Method for determining discontinuous reception activation state and terminal
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a terminal for determining a discontinuous reception activation state.
Background
In the fourth generation mobile communication system (4G system) and the fifth generation mobile communication system (5G or NR system), discontinuous Reception (DRX) is introduced. The DRX may allow a User Equipment (UE) to periodically enter a sleep state at some time without monitoring a Physical Downlink Control Channel (PDCCH) subframe, and wake up from the sleep state when monitoring is needed, so as to enable the UE to achieve a power saving purpose.
The DRX mechanism in connected state is shown in fig. 1: the period of time identified as "On Duration" is the time that the UE monitors the downlink PDCCH subframe, during which the UE is awake. The period of time identified as "Opportunity for DRX" is the DRX sleep time, i.e. the UE enters a sleep state without monitoring PDCCH subframes for power saving. As can be seen from fig. 1, the longer the time for DRX sleep, the lower the power consumption of the UE, but the delay of the corresponding traffic transmission will increase. "availability for DRX" may also be described as DRX off, or DRX inactive state.
In the prior art, when the UE is in DRX off state, if uplink UL data arrives, the UE may perform UL transmission. Therefore, when the location of the resource configured with the grant does not match the time of the DRX active state, the UE may send data in the DRX off state, so that the terminal enters the DRX active state, thereby increasing power consumption of the terminal.
