Abstract:
The present disclosure presents a method and an apparatus for inter radio access technology (IRAT) cell reselection. For example, the method may include identifying that a user equipment (UE) in an idle or a discontinuous reception (DRX) mode is camped on a cell of a first RAT, determining that the cell the UE is camped on is not broadcasting any neighbor cell of a second RAT, scanning for one or more frequencies of the second RAT based on the determination, and triggering a cell reselection to a cell of the second RAT, wherein the cell of the second RAT is associated with a frequency identified during the scanning. As such, an autonomous IRAT cell reselection may be achieved.
Abstract:
A measurement reporting method reduces battery waste. A UE receives a list of GSM neighbor cells and measures the signal strength of each of the GSM cells in the list. The UE performs base station identity code (BSIC) confirm/reconfirm procedures only for the cells having a signal strength above a threshold.
Abstract:
A method for tone detection includes wireless communicating on a first radio access technology (RAT). A determination is made of whether a gap generated by at least one idle timeslot in the first RAT communications is sufficient to perform tone detection but not sufficient to perform base station identity code (BSIC) verification of a second RAT. The halting of the performance of tone detection of the second RAT is made when the gap is not sufficient to perform BSIC verification.

Abstract:
An intelligent buffer size reporting process includes determining whether a signal strength of a first radio access technology (RAT) is below a first threshold value. A false buffer size of zero is reported when the signal strength of the first RAT is below the first threshold value for a period of time. A signal strength of a second RAT is measured using uplink timeslots resulting from the reported false buffer size of zero.
Abstract:
A measurement reporting method to avoid strong interference includes measuring all cells on a neighbor frequency indicated by a network on a neighbor list. A first and second set of cells are identified. The identified first set of cells are from the neighbor list and have a first signal strength a first predefined amount above a serving cell signal strength. The second set of cells are not on the neighbor list and have a second signal strength above a first threshold signal value. The first signal strength of the first set of cells and the second signal strength of the second set of cells are compared to determine whether to send a measurement report for the first set of cells.
Abstract:
A method of wireless communication adjusts the transmit power for high speed data communications. A UE determines whether a random access channel is configured on an uplink traffic time slot. When the random access channel is configured on the uplink traffic time slot, the UE transmits a high speed data channel with adjusted transmit (TX) power based at least in part on transmit power used for a scheduling request.
Abstract:
Methods and apparatuses for predicting candidates for cell reselection are presented. In some embodiments, such a method may include determining, by a mobile device, a current direction of motion of the mobile device; determining, by the mobile device, based on network topology information, that at least two cells of a plurality of cells are located in the current direction of motion of the mobile device; prioritizing, by the mobile device, the at least two cells of the plurality of cells for reselection; measuring, by the mobile device, signal properties of the at least two prioritized cells based on the prioritizing; and selecting, by the mobile device, a first cell of the at least two prioritized cells for reselection, based on: a location of the first cell and the signal properties of the first cell.
Abstract:
A method of wireless communications includes determining a period of time to trigger inter-radio access technology (IRAT) cell reselection. The method also includes adjusting the period of time accordingly, in which the adjusting is based on a target cell signal strength, the target cell belonging to a different RAT than a source cell. The period of time may also be determined based on the source cell signal strength and/or target cell signal strength, and adjusted accordingly.
Abstract:
The scheduling rate of the synchronization channel (SCH) base station identity code (BSIC) is adapted based on target cell signal metric such as, the signal quality and/or signal strength. The scheduling rate is decreased when the target cell metric is below a first threshold value and is increased when the target cell metric is above a second threshold value. The scheduling rate may also be adapted based on a serving cell signal metric.
