Abstract
Provided are a user equipment and a wireless communication method for LAA. The user equipment comprises: a receiver operative to receive a UL grant which schedules a subframe for UL transmission; a first circuit operative to perform LBT; a transmitter operative to transmit a PUSCH in the scheduled subframe starting from one available starting position of multiple candidate starting positions in the scheduled subframe if the LBT is successful. According to present disclosure, it is possible to increase the possibility that PUSCH could be sent in the scheduled subframe after LBT.
Claims20
A base station comprising:
- a transmitter, which, in operation, transmits an uplink grant indicating a time resource used for an uplink shared channel (PUSCH), the time resource comprising of a plurality of symbols;
- and
- a receiver, which, in operation, receives the PUSCH transmitted from one position selected from multiple positions in the time resource,
- wherein the multiple positions include a first symbol and an eighth symbol in the time resource, and a same transport block size is used in case of the PUSCH having a length of 14 symbols transmitted from the first symbol and in case of the PUSCH having a length of 7 symbols transmitted from the eighth symbol.
A communication method comprising:
- transmitting an uplink grant indicating a time resource used for an uplink shared channel (PUSCH), the time resource comprising of a plurality of symbols;
- and
- receiving the PUSCH transmitted from one position selected from multiple positions in the time resource,
- wherein the multiple positions include a first symbol and an eighth symbol in the time resource, and a same transport block size is used in case of the PUSCH having a length of 14 symbols transmitted from the first symbol and in case of the PUSCH having a length of 7 symbols transmitted from the eighth symbol.
A communication apparatus comprising:
- a receiver, which, in operation, receives an uplink grant indicating a time resource used for an uplink shared channel (PUSCH), the time resource comprising of a plurality of symbols;
- and
- a transmitter, which, in operation, transmits the PUSCH from one position selected from multiple positions in the time resource,
- wherein the multiple positions include a first symbol and an eighth symbol in the time resource, and a same transport block size is used in case of the PUSCH having a length of 14 symbols transmitted from the first symbol and in case of the PUSCH having a length of 7 symbols transmitted from the eighth symbol.
