Using DTX and DRX in a wireless communication system

摘要

Systems, methodologies, and devices are described that can facilitate reducing power consumption associated with mobile devices. A mobile device can utilize a sleep mode controller that can facilitate selecting and/or switching to a desired sleep mode based in part on predefined sleep mode criteria. The sleep modes can include a non-sleep mode, light sleep mode, and/or deep sleep mode. The mobile device can employ an analyzer to evaluate information related to explicit signals, implicit signals, and/or the current sleep mode to determine whether a condition is met based in part on the predefined sleep mode criteria such that a transition to a different sleep mode is to be performed. If such a condition is met, the sleep mode controller can facilitate transitioning from the current sleep mode to a different sleep mode to facilitate reducing power consumption by the mobile device.

1. A method of wireless communication, comprising:
receiving wireless signalling including discontinuous reception (DRX) configuration parameters, the DRX configuration parameters defining a DRX configuration of a mobile device; implicitly activating the DRX configuration of the mobile device after receiving the DRX configuration parameters when the mobile device does not transmit and/or receive data for a configurable amount of time; cycling between a first discontinuous receive (DRX) cycle off period and a first DRX cycle on period in a first sleep mode of a mobile device; cycling between a first discontinuous transmit (DTX) cycle off period and a first DTX cycle on period in the first sleep mode; transitioning from the first sleep mode to a second sleep mode of the mobile device; cycling between a second DRX cycle off period and a second DRX cycle on period in the second sleep mode, the second DRX cycle on period having a different duration than the first DRX cycle on period; cycling between a second DTX cycle off period and a second DTX cycle on period in the second sleep mode, the second DTX cycle on period having a different duration than the first DTX cycle on period; monitoring transmission from a base station only during the DRX cycle on periods; and turning off radio frequency generation of the mobile device during the DTX cycle off periods.
