METHOD AND SYSTEM FOR UPLINK ACKNOWLEDGEMENT SIGNALING IN CARRIER-AGGREGATED WIRELESS COMMUNICATION SYSTEMS |
摘要 |
A base station includes a transmit path circuitry to transmit DL grant, data streams, and a control signal to configure a number of uplink transmit antenna ports PUCCH to a subscriber station. The base station also includes a receive path circuitry to receive ACK/NACK modulation in response to the data streams. If the subscriber station is configured to transmit ACK/NACK using one uplink transmit antenna port and channel selection with PUCCH format 1B, a modulation symbol is transmitted on one (PUCCH) i determined based at least partly upon a channel selection mapping table. If the subscriber station is configured to transmit ACK/NACK using two uplink transmit antenna ports and channel selection with PUCCH format 1B, the ACK/NACK modulation symbol is transmitted on two PUCCHs. |
