The present disclosure is directed to a user equipment and a base station which use a dynamic time division duplex (TDD) configuration mechanism. The present disclosure proposes implementing the dynamic TDD mechanism by imposing a restriction to the dynamic TDD configurations to adhere to a set of allowable dynamic TDD configurations.

An apparatus and method are provided for performing register renaming, whereby architectural registers from a set of architectural registers are mapped to physical registers from a set of physical registers. Available register identifying circuitry is provided which is responsive to a current state of the apparatus to identify which physical registers form a pool of physical registers available to be mapped by register renaming circuitry to an architectural register specified by an instruction to be executed. Configuration storage stores configuration data whose value is modified during operation of the processing circuitry, such that when the configuration data has a first value, the configuration data identifies at least one architectural register of the architectural register set which does not require mapping to a physical register by the register renaming circuitry. The available register identifying circuitry is arranged to reference the configuration storage, such that when the configuration data has the first value, the number of physical registers in the pool is increased due to the reduction in the number of architectural registers which require mapping to physical registers. This enables the performance benefits from performing register renaming to be improved, without the need to increase the number of physical registers within the physical register set.

The invention is applicable to the technical field of communication, and provides an automatic hybrid retransmission method based on dynamic TDD. The method comprises the steps as follows: TDD reference configuration of a first communication terminal which doesn't support the dynamic TDD function is configured; relations of transmission directions of corresponding subframes between the TDD reference configuration and the current TDD actual configuration are analyzed; and data scheduling for the automatic hybrid retransmission is allowed to be performed at subframes with the same transmission directions, and the data scheduling for the automatic hybrid retransmission is prohibited at subframes with different transmission directions.
