Abstract: Certain embodiments of the present disclosure provide techniques for selecting a new cell, from a plurality of cells in a boundary area between first and second coverage areas, for a wireless device. The first and second coverage areas may include, for example, include cells controlled by first and second operators or cells in different time zones. In either case, the techniques may facilitate giving preference to cells in a same coverage area as a current cell. The wireless device may then select a cell from the list of neighbor cells as the new cell.

Abstract: Embodiments provide methods, systems, and/or devices to identify and/or determine a closest base station to a multi-mode mobile device among the multiple wireless communications technologies, such as different Radio Access Technologies (RATs). Having identified a closest base station to the multi-mode mobile device among the multiple wireless communications technologies, the mobile device's location may be estimated using location information regarding the closest identified base station. In some cases, a handover or other procedure may be performed with respect to the mobile device and the closest identified base station. The multiple wireless communications technologies may include, but are not limited to, WiMAX, CDMA 1x, LTE, and/or EVDO.

Abstract: Methods and apparatuses are provided that include selecting measurement types for measuring neighboring cells based in part on a change in device location. Where a change in location is relatively small, a device can perform less precise more efficient measurements of the neighboring cells to conserve power and/or processing time than where the change in location is larger. The neighboring cells can operate on a difference frequency than a serving cell; thus, measuring the neighboring cells using more precise measurements can utilize radio frequency (RF) calibration over the different frequency. Where a change in device location is below a threshold, however, less precise measurements that do not use RF calibration can be utilized to measure the neighboring cells.

Abstract: Methods and apparatuses are provided for configuring resources at a device operating in a sleep mode of a wireless network. The device can use at least some of the resources for other purposes, such as scanning neighbor base stations, acquiring system parameters of the wireless network or other networks, etc., based in part on requirements of a current interval of the sleep mode. In an available interval, a serving base station may attempt to communicate with the device, and thus, the device can keep at least one receiver chain tuned to the serving base station while assigning other resources to communicate with other base stations. In an unavailable interval, the device can assign all resources for communicating with the other base stations.

Abstract: 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.

Abstract: The present invention relates to a method for determining a nearest base station with respect to a mobile station from M base stations. First, the mobile station compares strengths of M signals received from M base stations with each other to determine a first base station, which has a strongest signal among M signals. Then, P strength differences of the strongest signal with P signals selected from the other (M-1) signals respectively are obtained. Finally, the first base station is determined as being the nearest base station when all strength differences are respectively larger than a predetermined value.
