Terminal apparatus, base station apparatus, and communication method for repeated transmissions of PUSCH in a particular sub-duration
A terminal apparatus includes a determination circuitry that divides a certain duration having a length provided by a higher layer parameter into one or more sub-durations based at least on a downlink region; and a transmission circuitry that performs repeated transmissions for a PUSCH in a certain sub-duration among the one or more sub-durations. Phase continuity is maintained for the repeated transmissions for the PUSCH.
1 . A terminal apparatus comprising:
determination circuitry configured to determine a plurality of sub-durations within a duration, a length of which is provided by a higher layer parameter, based on a configuration of a time division duplex (TDD) pattern that is provided to the terminal apparatus; and
transmission circuitry configured to maintain power consistency and phase continuity for one or more physical uplink shared channel (PUSCH) instances within each of the plurality of sub-durations, wherein the power consistency and phase continuity are not maintained across the plurality of sub-durations,
wherein the determination circuitry is further configured to determine an end point of each of the plurality of sub-durations based on a start point of a downlink region configured by the TDD pattern.
2 . A base station apparatus comprising:
higher layer processing circuitry configured to provide, to a terminal apparatus, a higher layer parameter that indicates a length of a duration, which is used for determining a plurality of sub-durations based on a configuration of a time division duplex (TDD) pattern that is provided to the terminal apparatus; and
reception circuitry configured to receive one or more physical uplink shared channel (PUSCH) instances while power consistency and phase continuity are maintained within each of the plurality of sub-durations, wherein the power consistency and phase continuity are not maintained across the plurality of sub-durations,
wherein an end point of each of the plurality of sub-durations is determined based on a start point of a downlink region configured by the TDD pattern.
3 . A communication method performed by a terminal apparatus, the communication method comprising:
determining a plurality of sub-durations within a duration, a length of which is provided by a higher layer parameter, based on a configuration of a time division duplex (TDD) pattern that is provided to the terminal apparatus; and
maintaining power consistency and phase continuity for one or more physical uplink shared channel (PUSCH) instances within each of the plurality of sub-durations, wherein the power consistency and phase continuity are not maintained across the plurality of sub-durations,
wherein an end point of each of the plurality of sub-durations is determined based on a start point of a downlink region configured by the TDD pattern.
