User equipments, base stations and methods for uplink transmission without grant
A user equipment (UE) is described that communicates with a base station. The UE includes receiving circuitry configured to receive a Radio Resource Control (RRC) message including first information indicating that limited buffer rate matching is enabled. The receiving circuitry is also configured to receive the RRC message including second information containing a number of repetitions and a redundancy version (RV) pattern. The UE includes processing circuitry configured to apply, according to the first information, limited buffer rate matching for a circular buffer to store coded bits of a transport block (TB). The processing circuitry is also configured to produce RV(s) of repetition(s) of the TB from the circular buffer according to the second information. The UE includes transmitting circuitry configured to transmit the repetitions of the TB.

receiving circuitry configured to receive a Radio Resource Control (RRC) message including:
first information indicating that more than one configured grant (CG) Physical Uplink Shared Channel (PUSCH) transmission configurations are configured for the UE,
second information indicating a first frequency resource and a first periodicity for a first configured grant (CG) Physical Uplink Shared Channel (PUSCH) transmission configuration of the more than one CG PUSCH transmission configurations;
third information indicating a second frequency resource and a second periodicity for a second CG PUSCH transmission configuration of the more than one CG PUSCH transmission configurations; and
fourth information configuring a timer, a value of the timer being same for all the more than one CG PUSCH transmission configurations; and
transmitting circuitry configured to:
perform the first CG PUSCH transmission based on the second information and the value of the timer, and
perform the second CG PUSCH transmission based on the third information and the value of the timer.
