Abstract: A method, apparatus and computer program product are provided to facilitate the establishment of device-to-device communications, such as non-cellular communications or cellular communications in a licensed exempt band. A method and apparatus receive cellular signals including one or more beacon transmission parameters, such as a beacon transmission interval and an identifier, and a beacon transmission status flag. The method and apparatus may also determine that the beacon transmission status flag is set to authorize beacon transmissions and then cause non-cellular beacon signals to be repeatedly transmitted in accordance with the one or more beacon transmission parameters. The method and apparatus may also cause a device-to-device connection to be established following transmission of the beacon signals. The device-to-device connection may be either a non-cellular device-to-device connection or a cellular device-to-device connection.

Abstract: The invention allows coordinating transmissions and receptions for over-the-air communication between uncoordinated base stations of an OFDM based cellular radio network. A radio resource dedicated for OTAC between uncoordinated base stations of an OFDM based cellular radio network is divided into subchannels. Deployment information of the uncoordinated base stations is obtained at a mobility management unit. Transmission allocation information is determined at the mobility management unit based on the obtained deployment information, the transmission allocation information comprising for each of the uncoordinated base stations their respective at least one symbol in said subframe of said dedicated radio resource and their respective at least one subchannel for use in their respective over-the-air communication transmissions, such that simultaneous over-the-air communication transmissions between an uncoordinated base station and its target uncoordinated base station are prevented. To the uncoordinated base stations are transmitted their respective determined transmission allocation information.

Abstract: The present invention discloses a signaling method, an apparatus and a computer program for controlled transmission signal deferring utilizing both licensed and unlicensed frequency bands for carrier aggregation. In the method, a connection is established between a User Equipment and a base station. For example, based on a sensed interference level, a transmission deferring indication is generated regarding a secondary component carrier locating on an unlicensed band, in case the secondary component carrier is occupied. This indication may be generated and sent either by the base station or by the User Equipment. Finally, the secondary component carrier is deactivated for data transmission, for deferring data transmission for a certain time period. After the deferring time has passed, the data transmission can be re-performed on the same secondary component carrier, or through switching to another secondary component carrier in unlicensed spectrum.

Abstract: A method, system, and computer program product that provides a two-index system for clusters of small cells in a wireless network. A first index is employed for access to and identification of a serving cell within a cluster of small cells. A second index indicates a group of small cells for determining mobility control. The first index may be derived from primary/secondary synchronization signals, or from frequency/time division multiplex signal position. The second index may be indicated in system/master information block signals or predefined as a plurality of small cells identified by the first index for each cell. Determination of physical cell identification is aided by providing a plurality of primary/secondary synchronization (PSS/SSS) signal alternating configurations with indicator, wherein a maximum number of configurations is predefined. Signaling the PSS/SSS configurations by one of broadcast or dedicated signaling, said signaling indicating whether each configuration is one of periodic or aperiodic alternation.
