Estimating the term…
Channel estimation accuracy is improved by adjusting the power level of a physical control channel allocated to a receiver based on the transmission rate and/or transport format of a corresponding physical data channel allocated to the same receiver. The physical control channel may be a DPCCH, E-DPCCH or other type of physical control channel allocated to a receiver for facilitating uplink or downlink communication. In one embodiment, control channel symbols are transmitted for use in channel estimation by adjusting the power level of a physical control channel allocated to a receiver based on the transmission rate and/or transport format of a physical data channel allocated to the receiver (200). Control channel symbols are transmitted to the receiver over the physical control channel at the adjusted power level (202). The receiver uses the control channel symbols to perform channel estimation (204).
A method of transmitting symbols used for channel estimation, comprising:
A transmitter comprising a baseband processor configured to:
A receiver comprising a baseband processor configured to:
A method of performing channel estimation at a receiver, comprising:
