Patent ID: 8547884

Claim:
A method of communicating by a mobile device in a multi-cell wireless communications system, wherein the multi-cell wireless communications system is configured to utilize a plurality of operating frequency bands for downlink (DL) transmission and a plurality of operating frequency bands for uplink (UL) transmission, each operating frequency band having a center radio carrier frequency and an operation bandwidth, the method comprising: receiving a DL signal via a first DL operating frequency band of the plurality of DL operating frequency bands for DL transmission, the DL signal including DL-UL frequency band pairing information specific to a cell; decoding the DL signal to obtain the DL-UL operating frequency band pairing information; determining, based on the decoded operating DL-UL frequency band pairing information, a first UL operating frequency band of the plurality of UL operating frequency bands for UL transmission; and configuring radio frequency (RF) circuitry of the mobile device to operate in the determined first UL operating frequency band for UL transmission, wherein the mobile device is reconfigurable to operate using different ones of the plurality of UL operating frequency bands.
