Abstract: A wireless communication device (14) is configured for discontinuous reception. DRX, operation in a wireless communication network (10). The wireless communication device (14) receives a DRX configuration (26) from the wireless communication network (10). The DRX configuration (26) configures the wireless communication device (14) with respective durations of multiple on-duration timers (15) for a DRX group, where the DRX group comprises one or more serving cells of the wireless communication device (14). In some embodiments, the multiple on-duration timers (15) include an inner on-duration timer (15A) and an outer on-duration timer (15B), e.g., where running of the outer on-duration timer (15B) is a prerequisite for starting or re-starting the inner on-duration timer (15A).

Abstract: Systems and methods for signaling of traffic flow information for Discontinuous Reception (DRX) configuration are provided. A method of operating a UE for determining a flow type includes: receiving a configuration of flow identify information with an association between one or more of: Downlink Control Information (DCIs); Radio Network Temporary Identifier (RNTIs); a combination of fields; with one or more DRX configurations; monitoring a Physical Downlink Control Channel (PDCCH) in DRX Active Time; in response to receiving a PDCCH with DCI indication of a flow type, identifying the DRX configuration k associated to the DCI indication; and starting or restarting a corresponding timer in the next symbol after PDCCH reception. In this way, signaling for a flow type, DRX configuration, or DRX parameter value indication from a gNB to a UE can be provided, in order to optimize multiple DRX cycle configurations per Serving Cell, where one or more of the configurations are active simultaneously.

Abstract: A method performed by a UE for supporting multiple DRX cycle configurations. The method includes obtaining multiple DRX cycle configurations. The method also includes, for each DRX cycle configuration, identifying a set of one or more flows associated with the DRX cycle configuration.
