摘要: 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.

摘要: A user equipment includes circuitry which selects a random access preamble sequence, and a transmitter which transmits the random access preamble sequence to a base station in a frequency bandwidth of an unlicensed band, and performs at least one of a first operation and a second operation. In the first operation, the circuitry selects a first sequence as the random access preamble sequence, the first sequence having a length longer than a length of a random preamble sequence used for a licensed band, and the transmitter transmits the first sequence in the frequency bandwidth of the unlicensed band. In the second operation, the circuitry selects a second sequence as the random access preamble sequence, the second sequence having a length equal to the length of a random preamble sequence used for the licensed band, and the transmitter transmits the second sequence with repetitions in the frequency bandwidth of the unlicensed band.

摘要: Provided are a user equipment (UE), an eNode B (eNB) and a wireless communication method for Licensed-Assisted Access (LAA). A UE for LAA according to one embodiment can comprise: a first circuit operative to perform a first listen-before-talk (LBT) in a system bandwidth; a second circuit operative to perform a second LBT in an allocated bandwidth; and a transmitter operative to transmit a signal in the allocated bandwidth if the first LBT is unsuccessful and the second LBT is successful.

摘要: Provided are wireless communication methods and devices. In one embodiment, a wireless communication method performed by a wireless communication device comprises: transmitting a data packet repeatedly in multiple subframes including at least one normal subframe and at least one special subframe to another wireless communication device, wherein the available resources in the special subframe are different from that in the normal subframe, the data packet includes multiple modulated symbols which are divided into multiple modulated-symbol sets, in each subframe, each OFDM symbol is mapped by one of the modulated-symbol sets, and in every subframe, the modulated symbols in the same modulated-symbol set are mapped onto REs in one OFDM symbol in a fixed order. In another embodiment, multiple repetitions of the data packet are transmitted in each subframe, and in each special subframe, different repetitions are mapped onto REs with cyclic shift.

摘要: Provided are a resource scheduling method, a resource determining method, an eNB, and a user equipment. The resource scheduling method for wireless communication is performed by the eNB. The wireless communication involves at least a first carrier and a second carrier. The resource scheduling method includes: transmitting a DCI in the first carrier to a UE to schedule downlink resources for a PDSCH of the second carrier, wherein the eNB is able to start transmitting a burst in the second carrier at a flexible time independent of the subframe boundaries of the second carrier after the second carrier is occupied by the eNB, and the DCI for a flexible PDSCH of the burst different from the normal PDSCH of the second carrier contains information on the time period scheduled for the flexible PDSCH. The flexible PDSCH and its corresponding RS can reuse the DwPTS subframe structure for minimal specification impact.

摘要: Provided are wireless communication methods, a UE and an eNB. The wireless communication method performed by a UE includes transmitting transport block repetitions to an eNB, wherein one HARQ process includes multiple repetition sets of a transport block if one repetition set of the transport block is not enough for the eNB to successfully decode the transport block, each of the multiple repetition sets includes multiple repetitions of the transport block, each of the multiple repetition sets is followed by a feedback channel to indicate whether the transport block is successfully decoded by the eNB.
