摘要： Methods, systems, and devices are described for utilizing proactive feedback information during a handover of a mobile device from a source base station to a target base station. The mobile device may transmit handover messages to the target base station that includes feedback status information, which may include automatic repeat request (ARQ) information elements in some embodiments. The target base station may request that the source base station transmit packets to the target base station based on the received feedback status information. The source base station may transmit handover messages to the mobile device that include feedback status information in some embodiments. Some embodiments may provide for fast resumption of data transmission by utilizing the proactively sent feedback status information from a mobile device to a base station during handover. Some embodiments may reduce the bandwidth for transferring unnecessary data between base stations.

摘要： Avoidance of uplink synchronization oscillation in TD-SCDMA systems begins when a user equipment receives a downlink SS command from a Node B. The user equipment obtains a previous uplink timing, which may be from a previous sub-frame associated with the downlink SS command. The user equipment would obtain this previous sub-frame associated with the SS command directly from the Node B as an identification of the Node B's sub-frame delay. The user equipment will then calculate the uplink timing for its next updated uplink signal by combining the previous uplink timing with the synchronization adjustment associated with the SS command. The user equipment then transmits its next uplink signal using the new uplink timing.

摘要： A method and apparatus for adjusting and offsetting a power level of uplink transmissions from user equipment in a wireless communication system. In an aspect of the disclosure, a handoff from a source base station to a target base station includes the target base station determining a suitable power offset value and communicating this offset to the source base station. The source base station transmits a handover instruction including the offset to the user equipment (UE), and the UE transmits a synchronization code. The target base station then calculates a further power correction and transmits the correction with an acknowledgment of the synchronization code. The UE then sets the power for future transmissions based in part on the offset and correction values.

摘要： Methods and apparatus are provided for selecting identifying numbers associated with a mobile station (MS) having multiple subscriber identity modules (SIMs) such that the paging intervals for both identifying numbers are aligned. The MS having multiple SIMs may operate in a network via a particular radio access technology (RAT), such as Wideband Code Division Multiple Access (W-CDMA). By having aligned paging intervals, the MS may wake up only once during the paging cycles for the various identifying numbers rather than waking up multiple times, thereby reducing power consumption of the MS during idle mode compared to a conventional MS with multiple SIMs, and thus multiple identifying numbers.

摘要： Wireless communication in a multicarrier radio access network, such as a (TD-SCDMA) network, may be implemented where a user equipment (UE) maintains communication over various carrier frequencies in the multicarrier network. The UE will receive a downlink pilot channel transmitted on every subframe on a primary carrier frequency. The UE will also receive a downlink pilot channel transmitted on less than every subframe on a secondary carrier frequency The downlink pilot channel is sent in subframes on the secondary carrier frequencies using a particular period and offset to reduce or minimize interference.
