The device may receive, from an access point that provides network access via the unlicensed RF spectrum band, a request for a channel recommendation associated with the unlicensed RF spectrum band. The device may determine a set of recommended channels of the unlicensed RF spectrum band based on the channel availability information and the request for the channel recommendation. The device may provide, to the access point, information that identifies the set of recommended channels.



OVERLAY OF BEARERS IN A RADIO COMMUNICATION SYSTEM

Thu, 23 Feb 2017 08:00:00 EST

A radio system having multiple bearers overlays a relatively narrowband bearer such as P25 on a relatively wideband bearer such as LTE, for transmission of both uplink and downlink signals. The wideband bearer uses a spectrum of subcarriers which form a set of radio frequency blocks. One or more blocks or other related parts of the spectrum may be allocated to the narrowband bearer. In some cases the narrowband bearer may push through the wideband allocation using a relatively high power to dominate signals transmitted by the wideband bearer. Voice calls such as emergency calls using the narrowband bearer may be prioritised.



SMOOTH TRANSITION BETWEEN PREDICTIVE AND MOBILE-ASSISTED SPECTRAL ALLOCATION

Thu, 23 Feb 2017 08:00:00 EST

Technologies are generally described for providing a transition between predictive and mobile-assisted spectral allocation. In some examples, wireless devices may be enabled to determine adequacy of their allocated spectral path to meet their communication needs by analyzing signal-to-noise ratios (SNRs) of their assigned sub-carriers. If a wireless device determines a current sub-carrier to be inadequate based on the analysis, d may send information associated with preferred sub-carriers to a base station. The base station may determine one or more nearby good clusters based on a comparison of a sequence of received preferred sub-carriers and the spectral paths represented by the nearby duster centers, and select a re-allocated spectral path with shortest information distance to the sequence of preferred sub-carriers.



METHOD FOR TRANSMITTING AND RECEIVING SIGNAL FOR DEVICE-TO-DEVICE COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR SAME

Thu, 23 Feb 2017 08:00:00 EST

The present invention provides a method for transmitting and receiving a signal for device-to-device (D2D) communication and apparatus for the same, which are used in a wireless access system supporting D2D communication. As one aspect of the present invention, a method for transmitting and receiving a D2D signal by a terminal comprises the steps of: determining whether a D2D signal can be transmitted and received in at least one frequency band; transmitting, to a base station, information on a frequency band capacity; and generating the D2D signal according to the information on a frequency band capacity.

A base station apparatus of the present invention is a base station apparatus capable of performing communication with a terminal device, by using a frequency band that can be exclusively used and a frequency band that cannot be exclusively used, by applying a communication scheme, which is applied to the frequency band that can be exclusively used, to the frequency band that cannot be exclusively used, and the base station apparatus instructs the terminal device to perform the communication with the base station apparatus by applying the communication scheme to the frequency band that cannot be exclusively used, by notifying the terminal device of control information necessary for control so as to use the frequency band that cannot be exclusively used in the communication with the terminal device to which the communication scheme is applied, in a state where the frequency band that cannot be exclusively used is not used in the communication with the terminal device to which the communication scheme is applied.



Neighbor Awareness Networking Tree Mapping

Thu, 23 Feb 2017 08:00:00 EST

In embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, i.e., communication between the mobile stations without utilizing an intermediate access point. Configuration of NAN includes mapping of NAN clusters and multi-hop data routing within a NAN cluster. A wireless device may transmit a subscribe service discovery frame (SDF) to one or more neighboring wireless devices and receive a respective publish SDF from the one or more wireless devices, the respective publish SDF including respective wireless device information. The wireless device may maintain a data structure comprising the respective wireless device information. In some embodiments, the wireless device information may include an address, hop count, and/or service indications, e.g., for data routing and/or service discovery.
