POWER SAVING IN WIRELESS TRANSCEIVER DEVICE

摘要

The present disclosure relates to a method performed by a first wireless transceiver device (12a) in a device-to-device (D2D) communication network (10a) supporting wireless D2D link between the first wireless transceiver device and a second wireless transceiver device (12b) in the D2D network. The second wireless transceiver device is provided with access to a cellular communication network (10b) via the first wireless transceiver device. The method comprises receiving capability information from the second wireless transceiver device on wireless D2D communication resources. The method also comprises transmitting power saving information about a power saving mode configuration based on the received capability information to the second transceiver device. The power saving information comprises information about sleep periods and active periods of the second transceiver device. The method also comprises transmitting a sync signal with a timing based at least in part on the power saving mode configuration, for facilitating re-synchronization of the second wireless transceiver device with the first wireless transceiver device in conjunction with an end of a sleep period of the second wireless transceiver device in accordance with the power saving mode configuration. The disclosure also relates to a method performed by the second wireless transceiver device, as well as to the first and second wireless transceiver devices.
