    摘要: A BLE network includes a first piconet including a first master scanner and a first group of low-power slave/advertisers for transmitting wireless advertisements. Circuitry in the first master/scanner wirelessly scans to detect an advertisement transmitted by a first slave/advertiser of the first group and transmits a connection request in response to the detecting, and transmits a schedule for subsequent advertisements after an initial advertisement by the first slave/advertiser. Circuitry in the first slave/advertiser transmits the initial advertisement, receives an acceptance a resulting connection request, establishes association with the first master scanner, and then causes the first slave/advertiser to go to sleep, to wake up and transmit subsequent advertisements according to the schedule and accept resulting connection requests, and transmits available data to the first master/scanner, and goes back to sleep.

    摘要: A method performed by a first transceiver device in D2D communication with second transceiver devices in a cellular network comprises transmitting a reference signal comprising an identity of the first transceiver device, and receiving feedback messages from the second transceiver devices, where a feedback message comprises the identity of the first and an identity of the second transceiver device, and channel characteristics of a radio channel between the first and the second transceiver device, where the channel characteristics are estimated by the second transceiver device. The method further comprises deciding, based on the feedback messages, whether a second transceiver device should be included in a set of intended devices to which the first transceiver device will perform a transmission of a communication signal. The method also comprises performing a transmission of the communication signal to the set of intended devices, where the transmission is adapted to the set of intended devices based on the feedback messages received from the intended devices.
