  • Patent number: 10292133
    Abstract: A person may utilize multiple connected devices, such as smart watches, user equipments (UEs), smartphones, tablet computers, and/or the like, which may each be assigned unique phone numbers. Operators may assign a common phone number to the multiple connected devices; however, the phone number is not used in the access stratum path of a radio access technology resulting in multiple paging procedures being performed for the multiple connected devices. In implementations, described herein, a first UE, such as a smartphone, may obtain paging information associated with decoding paging messages for a second UE, such as a smart watch. The first UE may use the paging information to decode a paging message of a combined paging cycle established for the first UE and the second UE, thereby obviating a need for multiple paging cycles for the first UE and the second UE.

    Abstract: Certain aspects of the present disclosure provide techniques for defending against false semi-persistent scheduling (SPS) activation detection and/or missed SPS release. According to certain aspects, a user equipment (UE) may detect one or more conditions for a semi-persistent scheduling (SPS) activation or release are met based on a downlink transmission, generate one or more metrics related to downlink transmission, and determine a valid SPS activation or release has occurred if the one or more metrics satisfy one or more criteria. According to certain aspects, a UE may determine a valid semi-persistent scheduling (SPS) activation has occurred, detect a number of PDSCH CRC failures, and implicitly declare an SPS release based on the detection.

  • Patent number: 9942846
    Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for a user equipment (UE) to delay RLC retransmissions (e.g., during off-durations, including CDRX off-durations). According to aspects of the present disclosure, a UE may delay triggering an RLC retransmission of an RLC PDU until after a next opportunity for the UE to receive an RLC ACK of the RLC PDU. By delaying RLC retransmissions, a UE may be prevented from waking up from one or more CDRX off-durations and using power associated with waking up from the one or more CDRX off-durations.

  • Patent number: 9578601
    Abstract: Methods, systems, and devices are described for managing power of a user equipment (UE). A UE modem may determine the state of charge of the battery to determine that the battery is in one of two or more charge state levels, and may invoke one or more modem power saving modes based on the charge state level. Power saving modes may include, for example, reducing a number of available receive chains in a UE, initiating a time delay between one or more frequency scan requests performed by the UE, reducing a rate of neighbor search requests performed by the UE, providing a buffer status report (BSR) parameter that indicates a reduced amount of buffer data relative to an actual amount of buffer data for the UE, and/or adjusting a maximum transmit power level for an uplink channel.

  • Publication number: 20160150524
    Abstract: Certain aspects of the present disclosure provide methods for adapting one or more parameters for uplink transmissions based on a channel condition profile. An example method generally includes obtaining, from a base station, feedback relating to one or more uplink transmissions sent from the UE to a base station (BS); generating, based on the feedback, a channel condition profile of one or more channels associated with the one or more uplink transmissions; and taking one or more actions, based on the channel condition profile, to adjust at least one of a power, code rate, or modulation scheme for one or more subsequent uplink transmissions.

  • Patent number: 9287954
    Abstract: A method for antenna switching is described. The method includes transmitting using a first antenna. The method also includes determining that a trigger occurs to switch to transmitting using a second antenna. The trigger is based on a combination of a physical uplink shared channel (PUSCH) maximum transmit power level (MTPL) counter and a physical uplink control channel (PUCCH) MTPL counter. The method further includes switching to transmitting using the second antenna based on the determination.

  • Publication number: 20150351153
    Abstract: Methods, systems, and devices are described for improving discontinuous reception (DRX) periods using enhanced physical HARQ indicator channel (PHICH) decoding. A user equipment (UE) may determine that an uplink (UL) retransmission (ReTx) is unnecessary based on the content of the original UL transmission. For example, the transmission may include media access control (MAC) layer padding rather than relevant application layer data. The UE may then identify a DRX sleep period that includes the subframe where the ReTx would take place. In some cases, the DRX sleep period may include a subframe where the UE would otherwise receive an acknowledgement message (AM) from a base station. The UE may then enter a DRX sleep state. In another example, the DRX sleep period is based on the content of a received AM. If the UE receives an ACK, the UL ReTx may be unnecessary.

  • Publication number: 20150327156
    Abstract: A mobile device determines that a primary cell (PCell) and a secondary cell (SCell) belong to a same multicast-broadcast single frequency network (MBSFN) area or that the PCell and the SCell can broadcast the same service. The mobile device determines a communication state of the SCell. If the SCell is active, the mobile device compares signal quality on the PCell and the SCell and selects to decode broadcast content on the PCell or the SCell. If the communication state indicating the SCell is deactivated or released, the mobile device switches to decode the broadcast content on the PCell. If the SCell is released and if the mobile device determines that the PCell is also released, then the mobile device switches to decode the broadcast content on the PCell and initiates a neighbor cell search.

  • Patent number: 9179364
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus is a UE. The UE transmits data packets. The UE determines to implement a flow control to reduce a transmission rate of the data packets. The UE determines whether the data packets include known or potential real-time data packets. The UE refrains from implementing the flow control to reduce the transmission rate of the known/potential real-time data packets when the data packets include known/potential real-time data packets.
