Alignment of DRX cycles for downlink communication and D2D communication
Abstract
A wireless communication device ( 10 ) configures a first discontinuous reception, DRX, cycle for downlink, DL, communication of the wireless communication device ( 10 ) with a wireless communication network. A length of the first DRX cycle is defined in terms of a number of slots in the time domain. Further, the wireless communication device ( 10 ) configures a second DRX cycle for device-to-device, D2D, communication performed on resources of at least one resource pool to which a subset of the slots is assigned. A length of the second DRX cycle is defined in terms of a number of the slots from the at least one resource pool. Further, the wireless communication device ( 10 ) sets the length of the first DRX cycle and the length of the second DRX cycle under the condition that, for consecutive time periods of fixed length, each time period contains an integer number of the first DRX cycles and an integer number of the second DRX cycles.
