Abstract

A method and apparatus for concurrent wireless communications on multiple channels of the same frequency band. A wireless device receives a first data signal via a first transceiver chain while concurrently initiating a transmission of a second data signal via a second transceiver chain of the wireless device. The wireless device suspends updates to one or more tracking loops of the first transceiver chain in response to initiating the transmission of the second data signal. The updates to the one or more tracking loops may be suspended prior to transmitting the second set of data from the second transceiver chain. The wireless device may subsequently resume updates to the one or more tracking loops of the first transceiver chain after completing the transmission of the second data signal.

5. The method of claim 1, further comprising:

resuming updates to the one or more tracking loops of the first transceiver chain after completion of the transmission of the second data signal.

6. The method of claim 1, wherein the first data signal is received on a first wireless channel of a frequency band, the second data signal is transmitted on a second wireless channel of the frequency band, and the first wireless channel is different than the second wireless channel.
