Abstract

Multiple full channel quality indication (CQI) reports indicative of received signal quality for multiple carriers in wireless communication are transmitted in multiple time intervals of a CQI channel.

Claims

1. An apparatus comprising:

at least one processor configured to obtain full channel quality indication (CQI) reports for multiple forward link (FL) carriers, each full CQI report indicative of received signal quality for one FL carrier, and to send the full CQI reports for the multiple FL carriers in different time intervals on a CQI channel; and

a memory coupled to the at least one processor, wherein the at least one processor is configured to cycle through the multiple FL carriers and select one FL carrier at a time for sending full CQI report, and to send a full CQI report for each selected FL carrier in a time interval designated for sending full CQI report.

6. The apparatus of claim 1, wherein the multiple FL carriers are for a Code Division Multiple Access (CDMA) system.

2. An apparatus comprising:

at least one processor configured to obtain full channel quality indication (CQI) reports for multiple forward link (FL) carriers, each full CQI report indicative of received signal quality for one FL carrier, and to send the full CQI reports for the multiple FL carriers in different time intervals on a CQI channel; and

a memory coupled to the at least one processor, wherein the at least one processor is configured to obtain differential CQI reports for the multiple FL carriers for a particular time interval, to jointly encode the differential CQI reports for the multiple FL carriers to obtain a codeword, and to send the codeword on the CQI channel in the particular time interval.
