Embodiment 1
[0115] This embodiment provides a method for determining an uplink timing relationship, including the following operations:
[0116] When the FDD serving cell and the TDD serving cell are aggregated and support cross-carrier scheduling, the device determines the uplink HARQ timing relationship of the scheduled serving cell according to the type of the scheduled serving cell;
[0117] Specifically, when determining the uplink HARQ timing relationship of the scheduled serving cell according to the type of the scheduled serving cell: if the FDD serving cell is the scheduling serving cell and the TDD serving cell is the scheduled serving cell, the UE may determine in at least one of the following ways The uplink HARQ timing relationship of the TDD serving cell:
[0118] Method 1: The timing between PDCCH / EPDCCH and PUSCH on the TDD serving cell, or the timing between PUSCH and PHICH adopts the uplink HARQ timing relationship corresponding to FDD, and the timing between PUSCH and ret...
Embodiment 2
[0151] This embodiment provides a UE that can implement all the implementation methods in Embodiment 1 above, and the UE includes:
[0152] The first unit, when the FDD serving cell and the TDD serving cell are aggregated and support cross-carrier scheduling, the UE determines the uplink HARQ timing relationship of the scheduled serving cell according to the type of the scheduled serving cell;
[0153] The second unit sends uplink data according to the determined uplink HARQ timing relationship of the scheduled serving cell.
[0154] Wherein, when the FDD serving cell is the scheduling serving cell and the TDD serving cell is the scheduled serving cell, the first unit determines the uplink HARQ timing relationship of the TDD serving cell in the following two ways:
[0155] 1. The timing between PDCCH / EPDCCH and PUSCH on the TDD serving cell, or the timing between PUSCH and PHICH adopts the uplink HARQ timing relationship corresponding to FDD, and the timing between PUSCH and r...
Embodiment 3
[0180] This embodiment provides a node device, which may be a base station, and includes at least two units.
[0181] The first unit, when the frequency division duplex (FDD) serving cell and the time division duplex (TDD) serving cell are aggregated and support cross-carrier scheduling, the system determines the uplink hybrid automatic retransmission of the scheduled serving cell according to the type of the scheduled serving cell request (HARQ) timing relationship;
[0182] The second unit receives uplink data according to the determined uplink HARQ timing relationship of the scheduled serving cell.
[0183] Wherein, when the FDD serving cell is the scheduling serving cell and the TDD serving cell is the scheduled serving cell, the first unit determines the uplink HARQ timing relationship of the TDD serving cell in the following two ways:
[0184] Method 1. The timing between PDCCH / EPDCCH and PUSCH on the TDD serving cell, or the timing between PUSCH and PHICH adopts the up...
