Claim of US Patent No. 9,973,324

1. A transmission method used in UE for a TDD-FDD joint system, comprising:Step A: receiving a first DCI on the subframe n on a first carrier, wherein the first carrier is a FDD downlink carrier, n is an integer, and the first DCI is the uplink-scheduling DCI; and
Step B: transmitting the uplink data on PUSCH of a second carrier in the subframe n+k according to the scheduling of the first DCI, wherein the second carrier is a TDD carrier, k is the uplink scheduling delay of the uplink reference frame configuration of the second carrier on the subframe n;
wherein for frame configuration #{0, 1, 2, 3, 4, 5, 6}, the first DCI comprises ULI and DAI bits only when the uplink reference frame configuration is configuration #0.
