Abstract: A method for improving the reliability of a channel quality indicator (CQI) message in a wireless communications network begins with receipt of the CQI message. The CQI message is then decoded, and a decision metric value for each symbol in the CQI message is computed. A largest decision metric value and a second largest decision metric value for the CQI message are determined. The reliability of the CQI message can be determined by comparing the two largest decision metric values. This method may be applicable to high-speed downlink packet access in time division duplex, frequency division duplex, or other modes of transmission.

Abstract: An analog/digital gain control device avoid some of the requirements associated with the nature of a closed-loop AGC circuits and which meets the remaining requirements without much difficulty uses an analog to digital conversion method that increases the number of effective ADC bits by compressing the baseband input analog signal using a logarithmic circuit. After the compressed analog signal is converted into a digital signal, a digital anti-log process or look-up table (LUT) is used to expand the digital signal back to the original linear scale. The word size of the output of the anti-log process is larger than the input word size due to the nature of the anti-log function. To reduce the word size of the digital signal an open loop normalization technique can be applied.

Abstract: A technique for allowing a first and second group of users to share access to a communication channel such as a wireless radio channel is disclosed. The first group of users can be a group of legacy users such as those that use digital CDMA cellular telephone equipment based on the IS-95 standard. The second group of users can be a group of web surfers that code their transmissions using one of multiple formats. The first group of users can share one modulation structure such as, on a reverse link, using unique phase offsets of a common pseudorandom noise (PN) code. The second group of users can share another modulation structure, but in a manner that is consistent and compatible with the users of the first group. Specifically, the users of the second group may all use the same PN code and code phase offset. Each channel used by the second group of users can be uniquely identified by a corresponding unique orthogonal code.

Abstract: A method for performing transport format combination indicator (TFCI) processing in a wireless communications system begins by collecting received samples for a timeslot. Processing of the received samples for the timeslot that does not require a transport format combination (TFC) code list or a TFC code list valid indicator is performed. Next, a TFCI value for the timeslot is received and is processed at the timeslot rate, producing the TFC code list and the TFC code list valid indicator. Then processing in the timeslot that requires the TFC code list or the TFC code list valid indicator is performed.
