Abstract
In a method of multipath acquisition for a dedicated traffic channel, path positions of the traffic channel that have desired signal energy for processing in a base station receiver may be determined as a function of pilot signal information and other control information contained in a control part of the traffic channel.

A method of multipath acquisition for a dedicated uplink traffic channel, comprising:
- determining path positions of the traffic channel that have desired signal energy for processing in a base station receiver as a function of pilot signal information and other control information contained in a control part of the traffic channel.
A method of multipath acquisition for a dedicated uplink traffic channel, comprising:
- determining path positions of the traffic channel that have desired signal energy for processing in a base station receiver from control bits in a control part of the traffic channel including pilot signal bits and one or more of transmit power control (TPC) bits, feedback information (FBI) bits and transport-format combination (TFCI) bits.
A method of calculating frame energy of a dedicated uplink traffic channel frame for multipath acquisition of one or more path positions of the frame that are received by a base station receiver, comprising
- descrambling and despreading a filtered output of a traffic channel frame received by the base station receiver, which corresponds to a given path position, into a plurality of output symbols corresponding to control information in a control part of the frame,
- accumulating output symbols corresponding to pilot signal bits within a slot of the frame and symbols corresponding to one or more of transmit power control (TPC) bits, feedback information (FBI) bits and transport-format combination (TFCI) bits in the given slot, and
- calculating L2 norms for the pilot symbols and one or more of the TPC, FBI and TFCI symbols over the slot, wherein the calculated L2 norms of the accumulated symbols for the pilot signal and one or more of the TPC, FBI and TFCI bits are accumulated over the traffic channel frame to determine the traffic channel frame energy for the given path position.
