Abstract
A communication method applicable for a LTE TDD system is disclosed. The communication method includes: if a radio frame has a plurality of UL sub-frames, adopting a flexible TTI bundling operation on at least one of the UL sub-frames in the radio frame; and when the radio frame is changed from a first configuration into a second configuration, the HARQ timing for a eNB to transmit ACK/NACK messages for the bundled UL sub-frames is the same as the HARQ timing for the eNB to transmit ACK/NACK messages for the last sub-frame of the bundled UL sub-frames in the second configuration.

A communication method applicable for a LTE (Long Term Evolution) TDD (Time Division Duplex) system, comprising:
- if a radio frame has a plurality of UL (uplink) sub-frames, adopting a flexible TTI (transmission time interval) bundling operation on at least one of the UL sub-frames in the radio frame;
- and
- after the radio frame is changed from a first configuration into a second configuration, the HARQ (Hybrid Automatic Repeat Request) timing for a eNB (evolved NodeB) to transmit ACK/NACK (Acknowledgmen/Negative-Acknowledgmen) messages for the bundled UL sub-frames is the same as the HARQ timing for the eNB to transmit ACK/NACK messages for the last sub-frame of the bundled UL sub-frames in the second configuration.
A communication method applicable for a LTE TDD system, comprising:
- if a radio frame has a plurality of UL sub-frames, adopting a flexible TTI bundling operation on at least one of the UL sub-frames in the radio frame;
- and
- after the radio frame is changed from a first configuration into a second configuration, wherein the first configuration and the second configuration belong to a set of allowed dynamic TDD configurations, the HARQ timing for a eNB to transmit ACK/NACK messages for the bundled UL sub-frames is determined according to a UL HARQ reference TDD configuration corresponding to the set of allowed dynamic TDD configurations.
A communication method applicable for a LTE TDD system, comprising:
- if a radio frame has a plurality of UL sub-frames, adopting a flexible TTI bundling operation on at least one of the UL sub-frames in the radio frame;
- and
- after the radio frame is changed from a first configuration into a second configuration, the HARQ timing for a eNB to transmit ACK/NACK messages for the bundled UL sub-frames is at a fixed sub-frame regardless of the second configuration.
A communication method applicable for a LTE TDD system, comprising:
- switching a TDD configuration from a first configuration to a second configuration, wherein the first configuration supports a TTI bundling operation and the second configuration does not support the TTI bundling operation;
- and
- suspending the TTI bundling operation after switching to the second configuration.
