    摘要： Carrier management in a wireless communication device assigned a set of two or more carriers by a wireless communication network is disclosed. In one aspect, a method of carrier management includes transmitting data over the wireless communication network on one or more carriers forming a subset of active carriers from the set of carriers assigned to the wireless communication device. A first performance metric is determined indicative of operating conditions across the set of carriers assigned to the wireless communication device. A desired number of carriers on which to transmit data based on the first performance metric is determined. The desired number of carriers on which to transmit data is compared with the number of carriers in the subset of active carriers. The subset of active carriers is dynamically adjusted based on the comparison and subsequent data is transmitted over the wireless communication network using the adjusted subset of active carriers.

    摘要： A method and apparatus for providing soft handoff in a third generation code division multiple access (CDMA) wireless communication system 34. The method comprises establishing communication between the wireless communication device 10 and the at least one serving base station 20, monitoring the reverse channel signal strength from the wireless communication device 21b, 22b, 23b, 24b, 25b, 26b from at least one neighboring base station, transmitting to a base station controller 31 the wireless communication device signal strength 21c, 22c, 23c, 24c, 25c, 26c, detected at each neighboring base station 21, 22, 23, 24, 25, 26, compiling at the base station controller 31 a list of effective neighboring base stations periodically transmitting a neighboring base station list update message 30, 32 to the wireless communication device 10, storing the effective neighboring base station list as a neighbor set in the wireless communication device 10, performing forward channel signal strength searching of the neighbor set in the wireless communication device 10 and monitoring the signals from the effective neighboring base stations to accomplish a handoff between the at least one serving base station 20 and the receiving neighboring base station 21, 22, 23, 24, 25 or 26.
