Method of remapping hybrid automatic repeat request timeline in time division duplex uplink-downlink reconfiguration

摘要

A method of remapping Hybrid Automatic Repeat Request (HARQ) timeline in Time Division Duplex (TDD) uplink-downlink (UL-DL) reconfiguration, for a communication device in a wireless communication system is disclosed. The method includes being reconfigured from a first TDD UL-DL configuration in a first radio frame to a second TDD UL-DL configuration in a second radio frame, determining a TDD UL-DL reference configuration according to UL subframe allocations of the first and second TDD UL-DL configurations in the first radio frame, and performing HARQ processes of the first TDD UL-DL configuration according to a HARQ timeline of the TDD UL-DL reference configuration during the first and second radio frames.

1. A method of remapping Hybrid Automatic Repeat Request (HARQ) timeline in Time Division Duplex (TDD) uplink-downlink (UL-DL) reconfiguration, for a communication device in a wireless communication system, comprising:
being reconfigured from a first TDD UL-DL configuration in a first radio frame to a second TDD UL-DL configuration in a second radio frame on a carrier; determining a TDD UL-DL reference configuration according to UL subframe allocations of the first and second TDD UL-DL configurations in the first radio frame, wherein the TDD UL-DL reference configuration has the least number of UL subframes among all TDD UL-DL reference configurations which include all UL subframes both in the first and second TDD UL-DL configurations; performing HARQ processes of the first TDD UL-DL configuration according to a HARQ timeline of the TDD UL-DL reference configuration during the first and second radio frames on the carrier; and performing UL HARQ processes of the second TDD UL-DL configuration according to a HARQ timeline of the second TDD UL-DL configuration during the second radio frame on the carrier.
