Abstract: The present invention relates to selection of synchronization source among various synchronization sources which include sources determining the synchronization signal from the network such as base stations (network nodes) or user equipments which receive the synchronization signal possibly over other hops from the base station, and which further includes sources which do not determine their synchronization signal from the network. The selection of the synchronization source is performed by choosing the source with the most reliable synchronization signal based on a metric calculated for each of the sources considered. In particular, the metric is based on the type of the source, number of hops between the network and the source and/or received signal quality. After selecting the source, the timing of the device is adapted accordingly.

Abstract: The invention relates to a method for allocating radio resources to a transmitting terminal for performing direct communication transmission over a direct link connection. The transmitting terminal receives a system information broadcast from the base station, which comprises information on a temporary transmission radio resource pool, indicating radio resources for performing a direct communication transmission, and comprises configuration information on the resource pool to limit the amount of time that the temporary radio resource pool is usable by the transmitting terminal.

Abstract: Provided are wireless communication methods for D2D communication and UEs therefor. A wireless communication method involves transmitting either a first DCI or a second DCI based on whether a first UE and a second UE are to be in a communication type of groupcast or unicast. In the wireless communication methods, the first DCI and the second DCI are scrambled by the UE ID of the second UE if the first UE and the second UE are in the communication type of unicast upon transmitting the first DCI and the second DCI, and the first DCI and the second DCI are scrambled by the group ID if the first UE and the second UE are in the communication type of groupcast upon transmitting the first DCI and the second DCI.

Abstract: The invention relates to a method for dynamically indicating a TDD reconfiguration to the mobile station by encoding the dynamic TDD re-configuration indication into the DCI or CRC calculated for the DCI. In one embodiment, the TDD configuration indication is implicitly encoded as an RNTI into the CRC, when scrambling the CRC for the DCI with a TDD-RNTI. In another embodiment, the TDD configuration indication is part of the DCI payload, while the CRC for the DCI is scrambled with a cell identifier, identifying the target cell for which the dynamic TDD re-configuration is to be applied. In still another embodiment, the TDD configuration indication is part of the DCI payload, where the DCI payload further includes an invalid parameter indicating to the mobile station that the DCI carries the TDD configuration indication.

Abstract: The invention relates to the allocation of radio resources by a transmitting user equipment to perform a plurality of direct SL transmissions to one or more receiving user equipments. The allocation of radio resources within a SC period is restricted, for the SC period, by a maximum number of SL processes with which a transmitting user equipment is configured. A plurality of SL grants is acquired. Among the acquired SL grants a number of those SL grants is selected that have most recently been acquired before the start of the subsequent SC period. A plurality of SL processes is associated such that each of the plurality of SL process is associated with a different one of the selected number of SL grants. For each of the plurality of the SL processes, the radio resources are allocated. Each of the plurality of SL transmissions comprises at least one SCI transmission and at least one data transmission over the SL interface.
