Procedure, base station and user equipment for uplink transmission without grant
A user equipment (UE) is described. The UE receives a RRC message including a periodicity. The UE also receives the RRC message including a first parameter. The UE further receives on a physical downlink control channel, DCI with CRC scrambled by a first RNTI that is different from a C-RNTI. The UE additionally performs, in a case that the first parameter is configured, a first PUSCH transmission based on the periodicity and a first offset value, the first offset value being configured by using the RRC message. The UE also performs, in a case that the first parameter is not configured, a second PUSCH transmission based on the periodicity and a second offset value, the second offset value being indicated by using the DCI, the second PUSCH transmission being activated by using the DCI.
