Abstract: A method and system for transmitting data from a UE in an OFDM system such as LTE. Information symbols are spread using a spreading code assigned to the UE and orthogonal to spreading codes of other UEs. The assigned spreading code has a spreading factor which is variable and dynamically selected based on one or more system performance criteria. The spread information symbols are transmitted in one or more LTE resource blocks. Spreading may be performed in the time domain, over a plurality of LTE time slots and/or resource elements.

Abstract: The present technology provides a computer-implemented method and system for performing frequency selective scheduling between a user equipment (UE) and a base station. The UE selects a sub-band within a predetermined system bandwidth based on observed radio conditions. The UE then communicates the selected sub-band to the base station. The base station then selects a LTE resource block having a frequency range falling within the sub-band. The selected resource block is then used for communication between the base station and the UE. The process may be repeated at a frequency related to the channel coherence.

Abstract: The present technology provides a method, apparatus and system for facilitating uplink communication from a user equipment (UE) to a base station in an LTE communication system. One or more frequency subcarriers within a predetermined LTE resource block are selected, covering less than the entire frequency range of the LTE resource block. The selected one or more frequency subcarriers are then used for communication from the UE to the base station.

Abstract: An aircraft-mounted base transceiver station (mBTS) for providing intermittent coverage in a cellular radio network. The mBTS utilizes the existing protocol of its terrestrial counterparts, thereby avoiding dual-mode devices and enabling common usage of terminal monitoring and device management systems for devices connected to a single radio access network even when outside terrestrial coverage areas. The aircraft follows a transient flight pattern, providing intermittent flyover connectivity for remote radio device such as machine-type devices. Connectivity may be store and forward. Channel usage may be adjusted to avoid interfering with terrestrial communication cells during flyover. Doppler effects due to aircraft speed may be accounted for. The mBTS may be configured to service in-range radio devices which are outside a Doppler-inhibited region and/or to prioritize communication with devices based on expected time outside the Doppler-inhibited region.

Abstract: Management of communication operations of wireless devices is provided. A traffic-control parameter is generated, for example at a base station, indicative of desired aspects of communication operations of the wireless devices. The one or more traffic-control parameters may comprise a delay parameter, such as a maximum value for generating random backoff times, and/or a connection-time parameter, indicative of the maximum length of time a wireless device can hold a connection. A bit sequence indicative of the one or more traffic-control parameters is generated and communicated to the wireless devices. A wireless device determines the traffic-control parameter based on the communicated bit sequence and adapts its operation based thereon.

Abstract: A method and apparatus for transferring identity information for temporary use by a wireless device, visiting a foreign operator network, is provided. A user is presented, at a kiosk, with an opportunity to download a temporary identity which is recognized by the operator network as belonging to a local subscriber, and the user may make a request for service. In response to the user-generated request for service, local identity information is transferred to the wireless device for use thereby. The transfer is short-range wireless communication from the kiosk to the wireless device. The temporary identity, once installed on the wireless device, makes the wireless device appear as a local subscriber. Upon termination of use, the temporary identity is returned to a pool and usable for another wireless device.

Abstract: The present technology provides an apparatus and a method for transmitting data via two or more FM signals in an interference avoiding manner. The apparatus comprises at least two FM transmitters. Each FM transmitter is configured to transmit a FM signal on a particular FM channel characterized by a certain carrier frequency that includes data and optionally one or more corresponding alternative frequencies (AFs). The apparatus further includes at least two receivers for receiving incoming electromagnetic radiation (EMR). At least one of the receivers is configured to receive incoming EMR associated with at least one of the FM channels, and another is configured to receive incoming EMR at least at frequencies outside of the FM channels. The controller is configured to separately control activation and deactivation of the FM transmitters and determine the carrier frequencies and the one or more AFs based upon incoming EMR.

Abstract: A method and apparatus for transferring identity information for temporary use by a wireless device, visiting a foreign operator network, is provided. The wireless device is identified as foreign to the operator network and presented with an opportunity to download a temporary identity which is recognized by the operator network as belonging to a local subscriber. The temporary identity, once installed on the wireless device, makes the wireless device appear as a local subscriber. Upon termination of use, the temporary identity is returned to a pool and usable for another wireless device.
