  • Publication number: 20230231681
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may switch the set of antennas that the UE uses to transmit sounding reference signal (SRS) transmissions. For example, the UE may switch from transmitting first SRSs that conflict with a scheduled communication from a first set of antennas to a second set of antennas (e.g., that is, the conflict may be at the first set of antennas). The UE may be transmitting second SRSs using the second set of antennas, and the switching may cause the UE to transmit the second SRSs using the first set of antennas instead. The second SRSs may not conflict with the scheduled communication (e.g., due to using different resources than the first SRSs), which may enable the UE to transmit the second SRSs and the scheduled communication using the same first set of antennas.

  • Patent number: 11595866
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a beam measurement report associated with a serving beam of the UE. The UE may determine that a timer, relative to transmission of the beam measurement report, has expired. The UE may perform a measurement of one or more neighbor beams based at least in part on determining that the timer has expired. Numerous other aspects are provided.

  • Publication number: 20220386172
    Abstract: A user equipment (UE) configured for dual connectivity with a split bearer configuration may transmit uplink data packets to one or both a master cell group (MCG) and a secondary cell group (SCG). The UE may transmit an uplink transmission from a packet data convergence protocol (PDCP) entity over one or both of a first radio link control (RLC) entity associated with the MCG and a second RLC entity associated with the SCG. The configuration including a transmit buffer threshold. The UE may receive, at the PDCP entity, an uplink switch start indication. The UE may activate the second RLC entity in response to receiving the uplink switch start indication. The UE may transmit a buffer status report according to a current transmit buffer level plus the transmit buffer threshold. Accordingly, the UE may communicate with the SCG based on the uplink switch start indication.

  • Patent number: 10057880
    Abstract: Disclosed are methods and apparatuses for providing notifications in a communication network of a plurality of Internet of Things (IoT) devices. In an aspect, a supervisor device in the communication network detects a notification directed to a wireless mobile device in the communication network and sends at least one instruction to at least a first IoT device of the plurality of IoT devices to reduce an operating volume or suspend operation of the first IoT device. The first IoT device receives the at least one instruction from the supervisor device and reduces the operating volume of the IoT device or suspends the operation of the IoT device in response to the at least one instruction.

  • Patent number: 10004087
    Abstract: An apparatus may communicate with at least two networks. The apparatus may be configured to opportunistically decode a channel from a first network and a channel from a second network in order to receive data from both networks. The apparatus may determine whether first data carried on a paging channel (PCH) is decodable from a subset of slots that carry the PCH. The subset of slots may be included in a set of slots that carry the PCH. When the PCH collides with a physical multicast channel (PMCH), the apparatus may decode second data carried on the PMCH instead of the first data when the first data is determined to be decodable from the subset of slots that carry the PCH, and decode the first data instead of the second data when the first data is not determined to be decodable from the subset of slots that carry the PCH.

  • Patent number: 9319863
    Abstract: Methods and devices are disclosed for enabling improved service acquisition on a first SIM of a multi-SIM wireless communication device. After the first SIM has lost service, the wireless device may detect a condition triggering a public mobile land network (PLMN) selection associated with the first SIM, receive an indication that service acquisition settings of the first SIM are set to a manual mode, and determine whether the second SIM is in idle mode. Upon determining that the second SIM is in idle mode, the wireless device may identify timing of a sleep cycle implemented by the second SIM, and perform the PLMN search using the first and second radio resources.

  • Publication number: 20150382361
    Abstract: Various embodiments implemented on a mobile communication device (e.g., a multi-carrier-capable communication device) mitigate the degraded performance experienced by an aggressor subscription performing transmit blanking on an interfering carrier frequency during a coexistence event by leveraging the availability of a non-interfering carrier frequency. In various embodiments, the mobile communication device may signal the aggressor subscription's network to adjust resources granted to the interfering carrier frequency and the non-interfering carrier frequency to improve overall data throughput and/or to reduce the likelihood of reception problems, such as increased retransmission requests from the network and stalls/delays in sending subsequent transport blocks. If no change in resources is signaled by the network, the mobile communication device may reduce a size of transport blocks transmitted on the interfering carrier frequency.

  • Publication number: 20150078334
    Abstract: Methods and apparatus are described for a method of cell acquisition, comprising obtaining, during an idle mode, a primary scrambling code (PSC) of a first cell of a first radio access technology (RAT) by a user equipment having a first subscription to the first RAT and a second subscription to a second RAT. Further, the methods and apparatus include performing a system information block (SIB) reading procedure for the first cell for one or more SIBs. Additionally, the methods and apparatus include determining whether any of the one or more SIBs are successfully decoded within a first time threshold during the SIB reading procedure for the first cell. Moreover, the methods and apparatus include aborting the SIB reading procedure for the first cell when the one or more SIBs are not successfully decoded within the first time threshold.
