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.

Abstract: Methods for enabling inter-User Equipment (UE) resource coordination are provided. More specifically, methods performed by a receiving device and a transmitting device for enabling inter-UE resource coordination are provided. The methods disclosed herein can help achieve a sound tradeoff between benefits of resource coordination and overhead associated with resource coordination. Specifically, the methods can help reduce network load and ineffective resource coordination message, obtain better suggestion in terms of rules and formats of the resource coordination message, and create a framework for combining different types of resource coordination formats.

Abstract: A wireless device (12A) receives a data transmission (22) from a peer wireless device (12B) on a sidelink (20) between the wireless device (12A) and the peer wireless device (12B). The wireless device (12A) transmits, to the peer wireless device (12B), a sequence (26) that is based on an identity (32B) of the peer wireless device (12B). Transmission of the sequence (26) conveys acknowledgement feedback (24) for the data transmission (22).

Abstract: In wireless device-to-device, D2D, communication data are transmitted directly from a first wireless device to a second wireless device. In response to the direct transmission of data, the second wireless device transmits feedback data indicating at least one quality of the data received in the second wireless device. More precisely, according to the invention, a radio access network node controls the direct transmission of data by means of downlink control information to the first and second wireless devices, and the feedback data are received in the radio access network node. The radio access network node preferably also uses the received feedback to control at least one of the first and second wireless devices.

Abstract: A wireless device configured for transmission using a transmission scheme other than a multi-antenna transmission scheme is provided. The wireless device includes at least one receiver configured to receive a transmission of a multi-antenna transmission scheme, and processing circuitry configured to perform at least one of a channel estimation function and measurement function using the received transmission of the multi-antenna transmission scheme, the multi-antenna transmission scheme remaining transparent to the wireless device.

Abstract: A device operates in a communications network by obtaining an adjustment term based on communications from the communications network and setting a time reference for the device based on the obtained adjustment term. The adjustment term is such that the set time reference for the device is common to at least one other device in communication with the device. The device further operates by communicating with the at least one other device in device-to-device communication, based on the common set time reference.

Abstract: The disclosure relates to a method performed by a UE, for using subframes of a radio access network for a D2D communication. The method comprises determining subframes available for D2D communication among subframes of the radio access network. The subframes available for D2D communication exclude a number of subframes of the radio access network, such that a periodicity of the D2D communication in number of subframes divides the number of subframes available for D2D communication. The method also comprises using the determined subframes for enabling D2D communication.
