摘要： A communication device supports a D2D (Device-to-Device) communication and includes a storage, a scheduler and a transmitter. The storage stores a first resource pool information that indicates first resource pool including control resources allocated to control information for transmitting data and a second resource pool information that indicates second resource pool including data resources allocated to data. The scheduler selects a first resource for transmitting control information from the first resource pool and selects a second resource for transmitting data from the second resource pool. The transmitter transmits the control information by using the first resource and transmit the data by using the second resource. The scheduler selects the second resource from the second resource pool according to a received signal intensity in at least one of resources included in the first resource pool and the second resource pool.

摘要： At a base station, a lookup table is prepared that for each index value among multiple different index values, associates repetition counts of different channels correlated with each other. The base station acquires reception information indicating a reception state of a wireless signal at a mobile station, determines a repetition count for each channel based on the reception information, and acquires from the lookup table, an index value corresponding to the respective repetition counts for the channels. The base station transmits to the mobile station, a wireless signal that includes the index value to notify the mobile station of the index value. The mobile station has a lookup table that for each index value among different index values, associates repetition counts of different channels correlated with each other and acquires the repetition counts of the channels from the lookup table, based on the index value from the base station.
