  • Patent number: 10194487
    Abstract: Architecture that allows a user to control the way a connection is made to a destination is described. A destination can be tagged with an attribute that defines how the connection to that destination should be routed. For example, a phone address book allows the user not only to enter the usual call recipient information such as name and telephone number, but also to add an attribute in the form of a network identifier associated with a network to be used when connecting to the destination. Where multiple networks are associated with the destination, the phone subsystem, recognizing that the destination now has multiple network IDs for connecting the call, can prompt the user to select the desired network pathway. The user can also tag the destination with a protocol that should be employed. Thus, not only will the phone be connected according to the network, but also the protocol.

    Abstract: Various aspects of the present disclosure provide for enabling at least one opportunity to transmit mission critical (MiCr) data and at least one opportunity to receive MiCr data in a time division duplex (TDD) subframe during a single transmission time interval (TTI). The single TTI may be no greater than 500 microseconds. The TDD subframe may be a downlink (DL)-centric TDD subframe or an uplink (UL)-centric TDD subframe. How much of the TDD subframe is configured for the at least one opportunity to transmit the MiCr data and how much of the TDD subframe is configured for the at least one opportunity to receive the MiCr data may be adjusted based on one or more characteristics of the MiCr data. The MiCr data may have a low latency requirement, a high priority requirement, and/or a high reliability requirement. Various other aspects are provided throughout the present disclosure.

  • Patent number: 10063275
    Abstract: A method of handling interference caused by inter-modulation in a network node site comprising a set of network nodes for wireless communication capable of communication with a set of stations for wireless communication is disclosed. The stations are wireless transceiver devices and communication from the network node to any of the stations is considered to be downlink communication and communication from any of the stations is considered to be uplink communication. The method comprises detecting an interference level on the uplink carrier frequency band for a subset of stations of the set of stations, and determining whether the interference level indicates probable inter-modulation interference. If the interference level indicates probable inter-modulation interference, the method proceeds with modifying a power control scheme for the subset of stations, and sending a parameter set based on the modified power control scheme to the subset of stations. A computer program and network node are also disclosed.

  • Patent number: 10051575
    Abstract: In some implementations, a method in a user equipment (UE) for adaptively determining a wakeup period includes determining a power level of a Downlink (DL) transmission from a base station during a first wakeup period within a Discontinuous Reception (DRX) inactive time. The UE deactivates a RF receiver in response to the determination of the second wakeup period. The UE activates the RF receiver at a beginning of the second wakeup period prior to a DRX active time. The UE receives a DL paging channel transmission during the DRX active time.

    Abstract: A computer-implemented method, system, and computer-readable storage media for scheduling physical resource blocks (PRBs) comprises a communication radio access network (RAN) base station with a scheduler that assigns one or more PRBs to a communication channel of a user device. The PRBs can be prioritized according to a radio frequency (rf) interference level across the contiguous band of PRBs. The rf interference level of a communication channel of the user device can be monitored by the scheduler. The scheduler assigns one or more of the prioritized PRBs according to the rf interference level of the PRBs and according to the rf interference level of the communication channel of the user device.

  • Patent number: 10034271
    Abstract: A mobile device (UE) may decode the Physical Control Format Indicator Channel (PCFICH) blindly, which may include obtaining resource elements (REs) that are reserved for the Physical Downlink Control Channel (PDCCH), based on a largest value of a control format indicator (CFI), finding a total number of control channel elements (CCEs) according to the obtained REs, numbering the CCEs, and decoding the PDCCH for the largest value of the CFI over the numbered CCEs. Accordingly, the UE does not need to decode the PCFICH) specifically. In some cases, the UE may indicate to the network that it is a constrained device, and the network may transmit control information using a reserved CFI value in response to the indication that the UE is a constrained device. The UE may then not decode the PCFICH, and decode the PDCCH based on the PDCCH occupying a first four OFDM symbols.
