Claim of US Patent No. 10,511,976

1. A method for radio communication performed in a radio terminal, the method comprising:selecting, from a resource pool including L subframes and M frequency domain resource blocks in a discovery period, NTX subframes and NTX sets of resource blocks to be used in NTX times of transmission of a discovery signal in the discovery period based on a first value n1 of a resource value autonomously selected by the radio terminal or a first value n1 of a parameter received from a base station,
wherein each set of the NTX sets of resource blocks is used in transmission of the discovery signal in a respective one of the NTX subframes, and
wherein with regard to the NTX sets of resource blocks, a value of a frequency domain shift from a second resource block set used in (j?1)th transmission to a first resource block set used in j-th transmission of the discovery signal in the discovery period depends on at least one of the first value n1 and a frequency domain position of the second resource block set in the resource pool, where j is an integer equal to or greater than 2.
