Methods, device and node for DRX of data

摘要

A method performed by a radio communication device for discontinuous reception, DRX, of data from a radio network node is disclosed. When information, indicating that data is scheduled to the radio communication device in a DRX cycle, is received (102, 104(Y)) during an initial part of a DRX cycle, a receiver of the radio communication device is activated (110) at the time data is received and deactivated (110) when data is not received. When information is not received (104(N)) or when the information indicates that no data is scheduled (108(N)) during a remaining part of the DRX cycle, the receiver is kept (106) deactivated. A method performed by the radio network node for enabling DRX of data by the radio communication device is disclosed, as well as the radio communication device and the radio network node. Micro sleep during single time slices, such as time slots, is enabled.

1. A method, performed by a radio communication device for discontinuous reception (DRX) of data from a radio network node of a wireless communications system, the method comprising:
determining whether information is received from the radio network node during an initial part of a DRX cycle, the information indicating whether data is scheduled to the radio communication device during a remaining part of the DRX cycle, wherein the DRX cycle comprises a plurality of time slices; in response to the information not being received, keeping a receiver of the radio communication device deactivated throughout the remaining part of the DRX cycle; in response to the information being received and indicating that no data is scheduled for the radio communication device, keeping the receiver deactivated throughout the remaining part of the DRX cycle; in response to the information being received and indicating that data is scheduled for the radio communication device for the remaining part of the DRX cycle, activating the receiver for the time slices of the remaining part of the DRX cycle in which data is scheduled and deactivating the receiver for the time slices of the remaining part of the DRX cycle in which data is not scheduled.
