Aspects of a method and system for detecting enhanced relative grants in a wireless communications system may include determining one or more signed signal power levels, wherein the one or more signed signal power levels may be positive E-RGCH signal levels or negative E-HICH signal levels. It comprises means for receiving the plurality of optical signals, optical means for selectively delaying the propagation of each of the plurality of optical signals, and means for outputting the time delayed optical signals. The anti-slip layer has a surface finish having a high coefficient of friction. The call request is received by a wireless network and communicated to a receiving handset.
