  • Patent number: 10178648
    Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may identify occurrence of one or more collisions of paging of a first radio access technology (RAT) and paging of a second RAT, wherein the second RAT is associated with an asynchronous deployment; and/or identify a target cell of the second RAT to reduce occurrence of the collisions, wherein the target cell has at least one of a different temporal system frame numbering or a different system frame timing configuration than a serving cell of the wireless communication device, and wherein the target cell is identified using a primary common control physical channel (PCCPCH) of the target cell. Numerous other aspects are provided.
    Type: Grant

  • 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: 9565687
    Abstract: Various embodiments include methods for reporting quality metrics of a wireless communication device to a network that includes scheduling, on the wireless communication device, a tune-away from a first carrier of a first subscription to a second subscription. Quality metrics of the first carrier before the tune-away begins are calculated and stored as frozen quality metrics. During the tune-away, the wireless communication device sends the stored frozen quality metrics to the network. The stored frozen quality metrics may continue to be sent to the network as long as the duration of the tune-away is shorter than a time threshold. If the duration of the tune-away exceeds the time threshold, the wireless communication device may calculate and send actual quality metrics of the carrier to the network.
