In a base station (), a controller () determines one set from among a plurality of sets, each of which including one or more candidates for a resource for an uplink (UL) control channel during initial access, and determines one candidate from among the one or more candidates for the resource, which is included in the determined set. A transmitter () indicates the determined set to a terminal () by higher layer signaling, and indicates the determined candidate by dynamic signaling. A receiver () receives a UL control signal, using the resource corresponding to the determined candidate in the determined set. In the base station, the association between a value to be indicated by the higher layer signaling and the plurality of sets is configured for each of one or more parameters relating to the initial access.

Base station, terminal, and communication method

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.

Device to device synchronization source selection

A method allocates radio resources for a transmitting user equipment (UE) to perform direct communication transmissions over a direct sidelink connection to one or more receiving UEs. At least two sidelink grant processes are provided in the transmitting UE for the transmitting UE to handle at least two sidelink grants within the same transmission control period. Each one of the sidelink grant processes is associated with an identification and can be associated with one sidelink grant. The transmitting UE acquires at least two sidelink grants and associates each of the acquired sidelink grants with one sidelink grant process. For each sidelink grant, the transmitting UE allocates radio resources according to the respective sidelink grant to perform a direct communication transmission of sidelink control information and of data over the direct sidelink connection. The transmitting UE performs a direct communication transmission per acquired sidelink grant within the same transmission control period.

The present disclosure provides a method of setting reserved subframes for indication of a resource pool by a bitmap, a user equipment, and a base station. In the present disclosure, the resource pool is used for transmitting or receiving sidelink signals within a system frame number cycle that includes predefined subframes and remaining subframes that are subframes after excluding the predefined subframes within the system frame number cycle. In the method, a number of the reserved subframes is determined so that the bitmap is repeated by integer times within the subframes after excluding the reserved subframes and the predefined subframes within the system frame number cycle. In the method, position of each of the reserved subframes is set, wherein at most two reserved subframes are set per n subframes within the system frame number cycle.
