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.

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.

Abstract: Aspects of the disclosure are directed to estimating a signal to interference ratio. A signal energy estimate corresponding to a received data transmission is generated. A noise to interference ratio estimate corresponding to the received data transmission is generated. A bias, corresponding to the noise to interference ratio estimate, is subtracted from the signal energy estimate. A signal to interference ratio estimate is determined corresponding to the signal energy estimate less the bias, and the noise to interference ratio estimate.

Abstract: Aspects of the present disclosure provide an apparatus and methods for operating the same that can improve out-of-sync and radio link failure handling in a W-CDMA network. A user equipment (UE) establishes a packet switched (PS) connection between the UE and a base station, wherein the PS connection includes a Fractional Dedicated Physical Channel (F-DPCH). The UE configures an in-sync threshold (Qin) and an out-of-sync threshold (Qout) for the F-DPCH, wherein values of the Qin and Qout are set higher than those of corresponding Qin and Qout of a Dedicated Physical Channel (DPCH). The UE further estimates a downlink (DL) Signal to Interference Ratio (SIR) based on one or more transmit power control (TPC) commands of the F-DPCH, and determines whether to release the PS connection based on a comparison of the estimated SIR and Qout of the F-DPCH.

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.

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. The mobile communication device may signal the network to return to normal resource allocations or transmit normal size transport blocks when the coexistence event ends.
