Abstract:
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 comprises: 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.
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.

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.
Abstract:
The present disclosure provides a wireless communication method and an eNode B and user equipment therefor. The method comprises a step of transmitting multiple PDCCH or EPDCCH repetitions respectively in multiple successive downlink subframes with a transmission repetition number and a transmission starting subframe. The transmission starting subframe is selected from a first starting subframe set corresponding to the first repetition number or a second starting subframe set corresponding to the second repetition number. The subframe indexes of any two adjacent starting subframes in the first starting subframe set are offset by a same first index interval, the subframe indexes of any two adjacent starting subframes in the second starting subframe set are offset by a same second index interval, and the second index interval is an integral multiple of the first index interval. According to the present disclosure, the resource blocking probability of different repetition numbers, UE's detection complexity can be decreased, and eNB's scheduling complexity.
