  • Patent number: 10291310
    Abstract: Systems, apparatuses, and methods for gap-based antenna measurement for antenna switch diversity, where there are fewer number of receivers or transmitters than the number of available antennas. The receivers may switch to additional antennas during a gap and switch back to the previous antennas. A device may select which antennas to use for communications based at least on measurements of additional antennas, thus supporting antenna switch diversity despite having fewer number of receiver chains.

  • Patent number: 10085181
    Abstract: The present disclosure provides a method, apparatus, and computer-readable medium that is able to avoid ping pong mobility when a redirection procedure fails. The apparatus may attempt to perform a redirection procedure from a first RAT to a target frequency of a second RAT. The apparatus may receive a redirection failure notification indicating that the target frequency of the second RAT is unavailable. The apparatus may refrain from initiating a reselection procedure to the target frequency of the second RAT for a predetermined time period. The apparatus may deprioritize the target frequency of the second RAT for the predetermined time period when the target frequency of the second RAT is unavailable and is present in an SIB received from the neighbor cell. The apparatus may generate a list of banned frequencies that includes the target frequency of the second RAT when the target frequency of the second RAT is unavailable.

  • Patent number: 9961600
    Abstract: Aspects described herein relate to using antenna-switched diversity (ASDIV) in wireless communications. A serving node can be communicated with using a serving radio access technology (RAT) and based on an ASDIV configuration, wherein the ASDIV configuration defines an antenna switching configuration including a state of one or more switches in an ASDIV switch group for switching between one or more antennas for the communicating based on sensing one or more parameters of the communicating. It can be determined whether a target RAT supports operating using a same ASDIV switch group as the serving RAT. A target node can be communicated with using the target RAT and based on the ASDIV configuration where the target RAT operates using the same ASDIV switch group as the serving RAT.

  • Patent number: 9807663
    Abstract: When a user equipment performs inter-cell measurement, it may desire to measure signal quality and signal level of a source radio access technology (RAT) cell and a target cell. The signal quality measurement may be Squal and the signal level measurement may be Srxlev. Because Squal is not defined for TD-SCDMA, a new measurement criteria is defined to allow proper comparison of source RAT cell measurements with target RAT cell measurements when a user equipment is considering switching to a target cell.

  • Publication number: 20170127439
    Abstract: Various embodiments may include methods for handling collisions between a first subscription and a second subscription of a wireless communication device. In various embodiments, a processor of the wireless communication device may determine whether there are persistent collisions between periodic paging wake-ups on the first subscription and periodic inter-RAT measurements on the second subscription. When persistent collisions are detected, the time for performing each inter-RAT measurement on the second subscription may be extended sufficient to enable completing inter-RAT measurements on the second subscription. The amount by which the time for performing inter-RAT measurements is extended may depend upon the timing and duration of the persistent collisions.

  • Patent number: 9516694
    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.
