Abstract
A method and apparatus in a communication system provide for concurrent processings of signals at the different frequencies. A received signal is down converted in a RF/IF system (490) to produce on-channel and out-of-channel received samples (305, 306). The on-channel received samples (305) are processed in a back-end portion 499 to decode on-channel information. The out-of-channel received samples (306) are processed to determine at least one of a link quality and global positioning system originated information in the back-end portion 499. The processings of the on-channel received samples (305) and the out-of-channel received samples (306) are performed essentially at the same time by the receiver back-end (499).

A method for processing a communication signal in a cellular communication system, comprising:
- receiving a signal comprising an on-channel component transmitted at a first frequency and at least one off-channel component transmitted at a second frequency, wherein the second frequency is different from the first frequency, and wherein reception of the on-channel component of the signal occurs uninterrupted by reception of the at least one off-channel component of the signal;
- converting the received signal into a base band signal, wherein the base band signal includes the on-channel component and the at least one off-channel component;
- applying one or more filters to the base band signal to produce on-channel received samples and off-channel received samples;
- processing the on-channel received samples to decode data transmitted over the on-channel component;
- and
- processing the off-channel received samples to decode data transmitted over the off-channel component, wherein the on-channel processing occurs contemporaneously with the off-channel processing.
