  • Patent number: 10804996
    Abstract: Various aspects of the present disclosure generally relate to wireless communication and techniques to prevent frequent beam switching. In some aspects, a user equipment (UE) may determine a duration of time that the UE dwells on a beam. The UE may update a data structure, stored in memory of the UE, to add or modify a stored duration value associated with the beam based at least in part on determining the duration of time that the UE dwells on the beam. The UE may determine that a condition associated with the stored duration value is satisfied. The UE may modify a priority of the beam in connection with a beam selection procedure based at least in part on determining that the condition associated with the stored duration value is satisfied. Numerous other aspects are provided.

  • Patent number: 10681583
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may measure a power value for each beam from one or more cells and calculate an average beam power for each cell. The UE may transmit these calculated averages to a base station in a report, and the base station may select a cell for communications based on the measurement report. The UE may also include a number indicating how many beams are used when calculating an average beam power, a ratio between a maximum and minimum beam power for each cell, two average beam powers based on two defined thresholds, or a combination of these measurements, in the transmitted report. The UE may add a bias to the average beam power for a particular cell to indicate a preference for that cell over the other candidate cells.

  • Patent number: 10218402
    Abstract: Apparatus and methods for method for a wireless communication device having a first Subscriber Identity Module (SIM) enabling a first subscription and a second SIM enabling a second subscription to manage communications over the first subscription and the second subscription, including but not limited to determining an error rate associated with the first subscription or a network congestion parameter associated with the first subscription and determining to skip at least one page decode on the second subscription based on the error rate associated with the first subscription or the network congestion parameter associated with the first subscription.

  • Publication number: 20190020756
    Abstract: The disclosure generally relates to providing a user with information regarding expected call connectivity and/or expected call quality prior to and/or during a call. For example, according to various aspects, a methodology that a wireless device can implement to predict call connectivity and/or quality may comprise measuring a current signal strength for at least one radio access technology (RAT) and mapping the current signal strength to a signal strength space division having multiple regions, wherein the multiple regions are each associated with an expected voice call connectivity and an expected data call connectivity. As such, user feedback information that indicates the expected voice call connectivity and the expected data call connectivity may be presented prior to receiving a request to initiate a call from the user.

  • Publication number: 20190007892
    Abstract: Methods, systems, and devices for wireless communication are described. System information may be updated during wireless communications. A base station may transmit an indication of such a change to a wireless device. In some cases, the indication may include a priority of the system information change. The base station may set a time duration for the system information change, and broadcast one or more information blocks (e.g., indicating the updated system information) during the time duration. Upon expiration of a timer associated with the time duration, the base station may return to transmitting the one or more information blocks to the wireless device in response to requests from the wireless device. In some cases, the system information change may be broadcast in response to receiving multiple requests to transmit the first type of information block from a plurality of wireless devices served by the base station.

  • Publication number: 20160191375
    Abstract: Aspects of controlling uplink transmissions on an enhanced dedicated channel in wireless communications include a user equipment configured to determine an unfavorable condition of an enhanced dedicated channel established with an enhanced network entity in response to failing to receive a threshold number of responses corresponding to uplink data transmissions on the enhanced dedicated channel, during an established connection with at least one non-enhanced network entity. Further, the aspects may include the UE suspending building of protocol data units for enhanced dedicated channel transmissions in response to determining the unfavorable condition of the enhanced dedicated channel. Additionally, the aspects may include the UE suspending uplink transmission on the enhanced dedicated channel in response to determining the unfavorable condition of the enhanced dedicated channel.

  • Publication number: 20160174187
    Abstract: Methods and devices for improving data throughput and page performance of a multi-subscription wireless communication device with a shared radio frequency (RF) resource may include detecting when a random access channel (RACH) procedure required on a modem stack associated with the first SIM in order to access a first network will coincide with a scheduled tune-away period for the shared RF resource corresponding to a reservation for activity on a second network supported by the second SIM. When such coincidence is detected, the wireless communication device may periodically transmit preambles to the first network with increasing transmission power until an acknowledgment is received or the scheduled tune-away period starts. When the scheduled tune-away period starts, the wireless communication device may pause transmission of preambles and record virtual preambles. When the tune-away period ends, the wireless communication device may continue the RACH procedure based on actual and virtual preambles.
