METHOD FOR TRANSMITTING/RECEIVING DOWNLINK PHYSICAL HARQ INDICATOR, USER EQUIPMENT AND BASE STATION
摘要
<p>A method for transmitting a downlink physical Hybrid Automatic Repeat reQuest (HARQ) indicator is provided, which includes steps of: modulating the downlink physical HARQ indicator into a modulated symbol; generating, based on the modulated symbol, an HARQ indication signal to be demodulated based on a User Equipment (UE) specific reference signal; and transmitting the HARQ indication signal using the antenna port(s). Also provided are a method for receiving a downlink physical HARQ indicator, a user equipment and a base station.</p>
