    Abstract: Techniques for channel configuration on a shared communication medium are disclosed. An access point may select a set of resource elements to carry an uplink control channel and transmit a configuration message including one or more configuration parameters associated with the selected set of resource elements to one or more access terminals. The access point may then receive uplink control signaling from the one or more access terminals via the selected set of resource elements. An access terminal may receive a configuration message including one or more configuration parameters for an uplink control channel from an access point and determine a set of resource elements configured to carry the uplink control channel based on the configuration message. The access terminal may then transmit uplink control signaling to the access point via the determined set of resource elements.

  • Patent number: 10256879
    Abstract: Components, systems, and methods for reducing location-dependent destructive interference in distributed antenna systems operating in multiple-input, multiple-output (MIMO) configuration are disclosed. Interference is defined as issues with received MIMO communications signals that can cause a MIMO algorithm to not be able to solve a channel matrix for MIMO communications signals received by MIMO receivers in client devices. These issues may be caused by lack of separation (i.e., phase, amplitude) in the received MIMO communications signals. Thus, to provide amplitude separation of received MIMO communications signals, multiple MIMO transmitters are each configured to employ multiple transmitter antennas, which are each configured to transmit in different polarization states. In certain embodiments, one of the MIMO communications signals is amplitude adjusted in one of the polarization states to provide amplitude separation between received MIMO communications signals.

  • Patent number: 10256962
    Abstract: An apparatus and method are provided for feeding back channel quality information and performing scheduling using the fed-back channel quality information in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA). In the OFDMA wireless communication system, forward performance degradation due to a decrease in an amount of reverse channel quality information is reduced, and also an increase in the reverse load due to channel quality information feedback is suppressed. A base station controls power of a physical channel using information fed back from a mobile station. In a method for feeding back channel quality information from the mobile station, sub-band-by-sub-band channel quality information is measured and channel-by-channel quality information of a number of channels is transmitted in order of sub-bands of better channel quality information. Average channel quality information for a total band is measured and transmitted.

  • Patent number: 10064179
    Abstract: Techniques for managing peak-to-average power ratio (PAPR) for multi-carrier modulation in wireless communication systems. Different terminals in a multiple-access system may have different required transmit powers. The number of carriers to allocate to each terminal is made dependent on its required transmit power. Terminals with higher required transmit powers may be allocated fewer carriers (associated with smaller PAPR) to allow the power amplifier to operate at higher power levels. Terminals with lower required transmit powers may be allocated more carriers (associated with higher PAPR) since the power amplifier is operated at lower power levels. The specific carriers to assign to the terminals may also be determined by their transmit power levels to reduce out-of-band emissions. Terminals with higher required transmit powers may be assigned with carriers near the middle of the operating band, and terminals with lower required transmit powers may be assigned with carriers near the band edges.

Taking into account known distance for the transmission as determined by onboard GPS and geographic databases, a power level may be set more precisely. Accounting for atmospheric conditions which may impact transmission as determined by onboard or received measurements of temperature, solar or other conditions may also permit a power level to be set more precisely. An obstruction database may be consulted to determine whether transmissions will degrade due to objects in between the transmitter and receiver, permitting power level, frequency, bandwidth or transmit/receive location to be adjusted accordingly.

If the current request is received on a non-preferred communication band, and a previous request was received on a preferred communication band within a pre-determined time, the system determines whether the signal strength associated with the previous request is weaker than a pre-determined threshold signal strength level for the preferred communication band. If so, the system responds to the current request. Otherwise, the system ignores the current request. If no recent request on the preferred communication band is received, and the signal strength associated with the current request is weaker than a pre-determined threshold signal strength level for the non-preferred communication band, the system responds to the current request on the non-preferred communication band. Otherwise, the system ignores the current request.

    Abstract: Methods, arrangement and network nodes for supporting inter-cell coordination of scheduling of radio resources subjected to inter cell interference. The methods involve identifying one or more radio resources which are subjected to inter-cell interference between a first cell and a second cell. The methods further involve deriving a respective service value related to service that could be provided in the respective first and second cell by use of the one or more radio resources. Further, transmissions in the one or more radio resources are controlled based on comparison of the service values, thus enabling inter-cell service value-based scheduling of the one or more radio resources, prioritizing services having the highest value per radio resource.

  • Patent number: 9832799
    Abstract: A mobile communication system according to the embodiment supports cellular communication in which a data path passes through a network and D2D communication that is direct device-to-device communication in which a data path does not pass through the network. A frequency division multiplexing scheme is applied to the cellular communication and a code division multiplexing scheme is applied to the D2D communication. The network assigns a spread code having orthogonality to a user terminal in response to a request from the user terminal. The user terminal performs the D2D communication by using the spread code assigned by the network.

  • Patent number: 9767329
    Abstract: Systems, apparatuses and methods provide for detecting the proximate placement of an external NFC reader to a specific location on a display surface. The display surface can be intended for viewing indicia and enabling interaction with an NFC communication device embedded within the display. A circuit can control an NFC security system that can scan for unauthorized tags affixed to the surface of a display. The NFC security system may be activated by an NFC enabled mobile phone placed proximate to the indicated region for receiving an NFC coded message from the display. An NFC security scan can be performed prior to the mobile phone reading the message from the intended NFC tag in the display. Enabling interactive display modes can allow for making selections indicated on the display or detecting motion gestures across the face of the display.

  • Patent number: 9693317
    Abstract: A configuration method for transmitting TPC command, a TPC command transmission method, and an apparatus. In the present invention, a radio network controller sends indication information to a terminal and a serving base station of the terminal to indicate a sending timeslot of an uplink TPC command of the terminal, so that sending timeslots of different TPC commands can be indicated for different terminals, and uplink TPC commands of multiple terminals are staggered in a timeslot. In this way, even if F-DPCHs of multiple terminals are configured with a same timeslot format, it can be avoided that locations of the uplink TPC commands are the same, and further a TPC peak-to-average ratio is lower than that in the prior art.
