Method and system for detecting enhanced relative grants in a wireless communications system

摘要

Aspects of a method and system for detecting enhanced relative grants in a wireless communications system may include measuring a signal power level of an Enhanced Hybrid ARQ Indicator Channel (E-HICH) and estimating a HOLD signal level of an Enhanced Dedicated Channel (E-DCH) Relative Grant Channel (E-RGCH), based on the measured E-HICH signal power level, wherein the E-RGCH is associated with the E-HICH. The signal power level of the E-HICH in Transmission Time Intervals (TTIs) associated with the E-HICH may be measured. The HOLD signal level may be measured by compensating the measured signal power level of the E-HICH based on whether the E-HICH signal comprises an acknowledgment (ACK), a discontinuous transmission (DTX), or a negative acknowledgment (NACK). The measured signal power level may be compensated by an offset. An UP signal level of the E-RGCH signal may be estimated based on the estimated HOLD signal level.

1. A method for processing communication signals, comprising:
determining, by a mobile terminal, a Transmission Time Interval (TTI) from among a plurality of TTIs in which an Enhanced Hybrid ARQ Indicator Channel (E-HICH) is scheduled to transmit; measuring, by the mobile terminal, a signal power level of the E-HICH over the determined TTI; comparing, by the mobile terminal, the measured signal power level of the E-HICH with a previous estimated signal power level, the previously estimated signal power level corresponding to a previously estimated power level of an acknowledgment (ACK), a previously estimated power level of a discontinuous transmission (DTX), or a previously estimated power level of a negative acknowledgment (NACK), to determine whether the E-HICH includes the ACK, the DTX, or the NACK; updating, by the mobile terminal, the a previously estimated power level of the ACK, the previously estimated power level of the DTX, or the previously estimated power level of the NACK with the measured signal power level based upon whether the E-HICH includes the ACK, the DTX, or the NACK; and determining, by the mobile terminal, an estimated HOLD signal level of an Enhanced Dedicated Channel (E-DCH) Relative Grant Channel (E-RGCH) by compensating the measured E-HICH signal power level by an offset corresponding to the ACK, the DTX, or the NACK.
