METHOD FOR TRANSMIT DIVERSITY OF HARQ-ACK INFORMATION FEEDBACK |
摘要 |
The present invention relates to a method for transmit diversity of HARQ-ACK information feedback in a wireless communication system, said system being adapted to employ transmit diversity and non-transmit diversity transmissions of HARQ-ACK information feedback, said method comprising: assigning uplink control channel resources and modulation symbols to HARQ-ACK states for at least two antenna ports such that said HARQ-ACK states are abled to be transmitted when associated uplink control channel resources are implicitly reserved, wherein at least one of said uplink control channel resources is assigned to more than one of said at least two antenna ports, and wherein uplink control channel resources and modulation symbols assigned to HARQ-ACK states for one of said at least two antenna ports is the same as when non-transmit diversity of HARQ-ACK information feedback is employed; and transmitting HARQ-ACK states assigned according to said assignment step on said at least two antenna ports. |
