Method for uplink acknowledgement/non-acknowledgement messages in a wireless communication system

摘要

A method for uplink ACK/NACK for LTE TDD. The method includes receiving a frame having multiple subframes wherein a plurality of subframes being downlink subframes and at least one subframe being an uplink subframe. One uplink subframe can contain an acknowledgment/non-acknowledgment (ACK/NACK) corresponding to at least one of the plurality of downlink subframes. To transmit ACK/NACKs, one uplink subframe for ACK/NACK is used in response to one of the plurality of downlink subframes. In addition, ACK/NACK responses can be bundled into one uplink subframe for at least two of the plurality of downlink subframes. In an embodiment, multiple ACK/NACK responses can be used in one uplink subframe that corresponds to at least two of the plurality of downlink subframes in a multiple feedback configuration. One uplink subframe for ACK/NACK responses and bundling multiple ACK/NACK responses is for a bundled feedback configuration.

1. A method comprising:
receiving in an uplink subframe an acknowledgment/non-acknowledgment response (ACK/NACK), wherein the response corresponds to multiple ACK/NACK for at least two of a plurality of downlink subframes; determining one of an uplink ACK/NACK physical uplink control channel (PUCCH) index using one of a user equipment identification and a parameter given in a dynamic downlink scheduling assignment; and determining an uplink ACK/NACK physical uplink control channel (PUCCH) index using a lowest control channel number and a parameter given in a last received dynamic downlink scheduling assignment.
