摘要： A method performed by a radio node for selectively providing synchronization information for Device-to-Device, D2D, communications between devices in a wireless communications network is provided. The radio node receives, when the radio node is providing synchronization information an indication to stop providing synchronization information for D2D communications. The radio node (120) determines whether to continue to provide synchronization information for D2D communications or not based on the received indication. A radio node for selectively providing synchronization information for Device-to- Device, D2D, communications between devices in a wireless communications network is also provided.

摘要： A method in a wireless terminal of a telecommunications system comprises the steps of using an enhanced physical downlink control channel to receive a downlink assignment of one or more downlink messages relating to a random access procedure, prior to an enhanced physical downlink control channel being formally configured for use with the wireless terminal. A corresponding method in a network node of a telecommunications system comprises the steps of transmitting a downlink assignment of one or more downlink messages relating to a random access procedure to a wireless terminal using an enhanced physical downlink control channel, ePDCCH, prior to the enhanced physical downlink control channel being formally configured for use with the wireless terminal. This has the advantage of relieving a PDCCH bottleneck of the telecommunications system.

摘要： A method of operating a first wireless communication device to perform D2D discovery includes obtaining multiple discovery message detection results, and determining a D2D discovery status of a second wireless communication device based on the multiple discovery message detection results. Using multiple discovery message detection results to determine the D2D discovery status of the second wireless communication device significantly increases the reliability of D2D discovery, thereby increasing the likelihood that a device available for D2D communication will be detected, while reducing the likelihood of false detections.

摘要： Disclosed are methods as well radio network nodes suitable for transmission 02 of a random access response message (e.g. RA MSG2) during a random access procedure. A method implemented by a radio network node, such as an evolved NodeB 20, may include generating a first MAC RAR (Medium Access Control Random Access Response) as well as generating a successive MAC RAR. The successive MAC RAR may be generated by differentially coding one or more bits of a field of the successive MAC RAR to produce a compressed successive MAC RAR.

摘要： PUCCH resource determination for HARQ-ACK transmission in response to ePDCCH-scheduled PDSCH or ePDCCH-indicated SPS release in a TDD radio communication system. Downlink control information (DCI) is received in a downlink subframe via an Enhanced Physical Downlink Control Channel (ePDCCH). A resource index for a Physical Uplink Control Channel (PUCCH) resource is determined, based on the lowest enhanced Control Channel Element (eCCE) index of the received DCI, a device-specific offset value, and an index ithat identifies the downlink subframe in a pre-determined set of one or more downlink subframes associated with an uplink subframe. The PUCCH resource is determined according to a formula that results in a sequential allocation of PUCCH resources in the uplink subframe with respect to the downlink subframes associated with the uplink subframe, for each of a plurality of sets of ePDCCH resources. HARQ feedback is transmitted in the uplink subframe, in the indexed PUCCH resource.
