Abstract: Allocating transmit power among two or more carriers assigned to a wireless communication device is disclosed. In one aspect, a method of allocating transmit power includes determining a total amount of data transmit power available at the wireless communication device for data transmission over the carriers. An efficiency metric is determined for each carrier based on the carrier's transmission characteristics and a portion of the total data transmit power is allocated to each carrier based on each carrier's efficiency metric.

Abstract: A method of wireless communication includes measuring and recording a path loss of a first downlink signal from a source base station, prior to attempting handoff from the source base station to a target base station. The path loss of a second downlink signal from the source base station is measured after unsuccessful handoff from the source base station to the target base station. A UE communicates with the source base station, after unsuccessful handoff, using an uplink timing corresponding to an uplink timing recorded prior to attempting handoff when a difference between the path loss of the first downlink signal and the path loss of the second downlink signal fails to meet a threshold value. A new uplink timing is used when the difference meets the threshold value.

Abstract: Methods and apparatus are provided for operating in a first RAN at a working frequency, determining a priority of measurement tasks enabled by the first RAN, and dynamically scheduling the tasks according to the priority. For certain aspects, the first RAN may be a TD-SCDMA network. The measurement tasks are intended to measure at least one parameter of a serving cell in the first RAN on a primary frequency, at least one cell in the first RAN on at least one frequency other than the primary frequency, one or more cells in at least one RAN other than the first RAN (e.g., a GSM network) or any combination thereof. This dynamic assignment allows the UE to make scheduling decisions on which frequencies and RANs to measure, as well as how often these frequencies and RANs are measured, thereby providing for more efficient use of idle slots over conventional haphazard scheduling.
