RELIABILITY DETECTION OF CHANNEL QUALITY INDICATOR (CQI) AND APPLICATION TO OUTER LOOP POWER CONTROL
First Claim
1. A method for determining a channel quality in wireless communications, comprising:
- receiving a high speed shared control channel (HS-SICH) transmission;
counting an expected number of HS-SICH transmissions;
counting a number of unsuccessful HS-SICH transmissions, wherein the number of unsuccessful HS-SICH transmissions includes a number of failed HS-SICH transmissions and a number of missed HS-SICH transmissions; and
periodically reporting the expected number of HS-SICH transmissions and the number of unsuccessful HS-SICH transmissions over a fixed time period, whereby the reporting is an indication of the channel quality.

Abstract
A method for determining a channel quality in wireless communications includes receiving a high speed shared control channel (HS-SICH) transmission. An expected number of HS-SICH transmissions and a number of unsuccessful HS-SICH transmissions are counted. The number of unsuccessful HS-SICH transmissions includes a number of failed HS-SICH transmissions and a number of missed HS-SICH transmissions. The expected number of HS-SICH transmissions and the number of unsuccessful HS-SICH transmissions over a fixed time period are periodically reported, whereby the reporting is an indication of the channel quality.
