Definitions

  • a user equipment needs to constantly monitor Physical Downlink Control Channel (PDCCH) in order to check if there is downlink data available. This consumes a lot of power.
  • PDCCH Physical Downlink Control Channel
  • DRX makes it possible for the UE to reduce power consumption by discontinuously receiving PDCCH: UE periodically enters a sleeping state for a certain period of time (OFF duration) during which PDCCH is not monitored before waking up for another period of time (ON duration) to monitor PDCCH for possible downlink data. DRX thus allows a reduction of power consumption.
  • the network configures UE with a set of DRX parameters, including "onDurationTimer” and “inactivityTimer” as defined in 3GPP specification TS 38.321.
  • DRX a set of DRX parameters, including "onDurationTimer” and "inactivityTimer” as defined in 3GPP specification TS 38.321.
  • different traffic flows may be established between UE and a serving base station, including video, audio and pose flows, either in uplink or downlink directions.
  • a base station may configure different overlaid DRX configurations to support such distinct traffic flows.
  • a method of wireless communication for controlling discontinuous reception by a user equipment connected to a wireless network node comprising:
  • a base station may punctually adjust one or more DRX configurations configured in a user equipment without having to send a whole DRX reconfiguration.
  • a base station may instruct the user equipment to update its DRX configuration to optimize power consumption. It is to be noted that such a DRX configuration update does not target the DRX cycle during which the configuration is received, but rather a distinct DRX cycle.
  • said first DRX cycle belongs to a first DRX configuration
  • said second DRX cycle belongs to a second DRX configuration
  • Such an arrangement makes it possible to adjust a specific DRX configuration based on a signaling received during an active period of a distinct DRX configuration. This allows a better reactivity when reducing power consumption. For instance, without such arrangement, a base station would need to wait for an activation period of a specific DRX configuration to transmit a signal instructing a user equipment to skip the next activation cycle, what would not be power-efficient. Instead, the base station can use the first available DRX activation slot to instruct a user equipment to skip next DRX cycle on a specific DRX configuration. This particularly advantageous in data flows involving XR, wherein several distinct data flows may be transferred using different DRX configurations.
  • said DRX update parameter comprises at least an identifier of said second DRX configuration.
  • the power saving signal includes an identifier of one or more DRX configurations that should be adjusted using said discontinuous reception configuration update.
  • said DRX update parameter comprises at least an instruction for skipping said at least one second DRX cycle.
  • a base station may therefore instruct a user equipment to skip one or more DRX cycles. For example, when a base station knows that there is no pending downlink data, it can instruct a user equipment not to wake up during one or more upcoming DRX cycles. This allows a power consumption reduction because user equipment will not wake up if there is no downlink data to receive.
  • said DRX update parameter comprises at least a number of DRX cycles to be skipped.
  • the skipping instruction included in the power saving signal is associated with a number of consecutive DRX cycles that should be skipped.
  • User equipment may then adjust DRX cycles by skipping a specific number of DRX cycles as instructed by the base station.
  • said DRX update parameter comprises at least an instruction for shifting said at least one second DRX cycle.
  • DRX cycles from a specific DRX configuration may be time-shifted.
  • the power saving signal may comprise a shift instruction allowing a user equipment to delay or advance the next DRX cycle and upcoming ones.
  • User equipment may then adjust DRX cycles by shifting specific DRX cycles according to the received instructions.
  • said DRX update parameter comprises at least a time offset for shifting said at least one DRX cycle.
  • Such an arrangement allows a base station to fine-tune user equipment DRX cycles to match downlink data arrival rate.
  • User equipment may thus adjust DRX cycles by shifting specific DRX cycles according to the time offset received in the DRX update parameter.
  • said power saving signal is carried over MAC CE and/or PDCCH.

  • the program can use any programming language, and be in the form of source code, object code, or of code intermediate between source code and object code, such as in a partially compiled form, or in any other desirable form.
