Abstract:
1. A method of dynamically switching secondary serving cells, the method comprising: transmitting a primary serving cell at a first carrier frequency to a user equipment; preconfiguring the user equipment to receive a first secondary serving cell at a second carrier frequency and a second secondary serving cell at the first carrier frequency, wherein the first secondary serving cell corresponds to dual cell high speed downlink packet access (DC-HSDPA) and the second secondary serving cell corresponds to single frequency, dual cell high speed downlink packet access (SFDC-HSDPA); determining, based in part on channel quality indicator (CQI) reports transmitted by the user equipment and loading of at least one of the first secondary serving cell or the second secondary serving cell, whether to dynamically switch between the first secondary serving cell and the second secondary serving cell; and transmitting a configuration message to instruct the user equipment to select at least one of the first secondary serving cell or the second secondary serving cell, wherein the configuration message is configured to instruct the user equipment to: select the second secondary serving cell when the first carrier frequency and the second carrier frequency are in the same band, and select the first secondary serving cell when the first carrier frequency and the second carrier frequency are in different bands.
