METHOD AND APPARATUS FOR PROVIDING BIASING CRITERIA FOR BINARY DECISIONS EMPLOYED BY A USER EQUIPMENT UE IN WIRELESS COMMUNICATIONS TO ENHANCE PROTECTION

摘要

According to the present invention, there is provided the use of a two-won (元) determination technique to obtain a reference for the deflection (bias) to which require unequal protection using a ratio (SIR) of the measured signal-to-interference a user equipment. Ratio (SIR) of the signal-to-interference is obtained from the channel estimated value. Ratio (SIR) of the signal-to-interference is compared with certain threshold values, the threshold value is selected to bias the decision towards the contrary NACK and ACK decision. This technique is applicable to all of the high-speed downlink packet glass to provide a deflection of the second won is determined for (HSDP), but the uplink and downlink applications, applications. Threshold value, the signal-to-ratio (SIR) a ratio (SIR) of the threshold value, for sufficiently small, the signal that is an error of low frequency of occurrence enough to accommodate interference or more of the interference can be accommodated it is not more than the threshold value as to avoid a large number of errors it is not set at a sufficiently large level.
