Abstract
A power saving method for monitoring data channel is proposed. The network node may indicate that the UE can enter a power saving mode by transmitting a DCI to the UE. The DCI may indicate a power saving duration and an additional monitoring duration. The power saving duration may indicate the length of the power saving mode and the starting point and the end point of the power saving mode. The additional monitoring duration may indicate that the UE needs to perform monitoring for a period of time before the power saving mode based on the first power saving duration indicated in the DCI.
Claims16
A method, comprising:
- receiving a first downlink control information (DCI) by a user equipment (UE) from a network node, wherein the first DCI indicates a first power saving duration and a first additional monitoring duration;
- determining whether data scheduled by the first DCI is decoded successfully;
- performing monitoring for a period of time based on the first power saving duration such that the first power saving duration is shortened based on the first additional monitoring duration before a power saving mode, in an event that the data scheduled by the first DCI is not determined to be decoded successfully;
- receiving a second DCI by the UE from the network node before entering the power saving mode based on the first power saving duration, wherein the second DCI indicates a second power saving duration and a second additional monitoring duration;
- and
- determining a duration of the power saving mode based on an overlapped time duration of the first power saving duration and the second power saving duration.
A user equipment (UE), comprising:
- a receiver, receiving a first downlink control information (DCI) from a network node, wherein the first DCI indicates a first power saving duration and a first additional monitoring duration;
- and
- a processor, determining whether data scheduled by the first DCI is decoded successfully;
- wherein the processor performs monitoring for a period of time based on the first power saving duration such that the first power saving duration is shortened based on the first additional monitoring duration before a power saving mode, in an event that the data scheduled by the first DCI is not determined to be decoded successfully;
- receives a second DCI by the UE from the network node before entering the power saving mode based on the first power saving duration, wherein the second DCI indicates a second power saving duration and a second additional monitoring duration;
- and determines a duration of the power saving mode based on an overlapped time duration of the first power saving duration and the second power saving duration.
