摘要： The present invention relates to the technical field of dynamic spectrum access. Synchronization of quiet periods for spectrum sensing can significantly benefit sharing of available secondary access spectrum between two or more wireless communication systems in the same geographic region (10). The object of the present invention is to provide a methodology by which quiet periods can be synchronized in time between different secondary access wireless communication systems. Quiet Period Clients (QPC) of secondary access wireless communication systems (1,2,3) are adapted to send requests to a Quiet Period Server (QPS) to obtain a quiet period rule set. The QPC receives from the QPS an answer specifying the quiet period rule set, and optional quiet period synchronization information. The systems(1,2,3) perform their transmissions in accordance with the received rules.

摘要： The technology described in this application provides a wide-area radio access information transmission scheme where the wide-area radio access information transmitter shares its radio resources with local radio access information transmitters. The radio resources may be divided for example in one or more of the time, frequency, space, and/or code domains. The wide-area radio access information transmitter sets aside and does not use some portions or "chunks" of its radio resources and allocates those unused portions or chunks for use by local radio access information transmitters to transmit local radio access information signals. In one non-limiting example embodiment, the radio resources include time slots, and during those time slots allocated to the local radio access information transmitters, the wide-area radio access information transmitter does not transmit, and thus, is quiet. Hence, those allocated time slots are referred to as "quiet periods" from the perspective of the wide-area radio access information transmitter. The wide-area radio access information transmitter can optionally explicitly signal what those resources are to simplify for the local radio access information transmitters who otherwise have to detect those resources themselves.

摘要： The disclosure relates to a network node of a wireless network, and to a related method of controlling interference generated by at least one white space device controlled by the network node. The method comprises transmitting (520) a request for information regarding channels available for secondary usage to the remote entity, and receiving (530) information from the remote entity, the information indicating a channel available for secondary usage, a critical position associated with said channel, and an interference threshold for the critical position. The method also comprises deriving (540) a constraint for the allocation of said channel to the at least one white space device, based on a position of the at least one white space device, the critical position, and the interference threshold, and allocating (550) said channel and a transmit power to the at least one white space device based on the derived constraint, whereby the interference generated in the critical position by the at least one white space device is kept below the interference threshold.

摘要： The present disclosure concerns radio communication. More particularly, the disclosure presents a contention based access channel signaling between a radio access network node, such as an evolved NodeB (eNB), and a User Equipment (UE). In one example embodiment, the UE receives 110 a data frame comprising multiple zones from an eNB. A zone of the multiple zones comprises an UE group identity as well as an indicator addressing a reserved contention-based access channel for use in another zone by those UEs having said UE group identity. Also, the UE group identity is retrieved120, or otherwise read, from the zone. If, or when, the UE group identity matches that of the UE, the UE may utilize130the addressed reserved contention- based access channel.

摘要： According to aspects of the invention, a radio signal that constitutes a secondary use is provided with a predefined identifier (11) that identifies the radio signal as a secondary use. The identifier (11) can be any suitable signal characteristic that somehow can be detected by a suitable radio receiver. The identifier (11) enables identification of an origin of the radio signal. That is, whether it originates from a primary user or a secondary user. It therefore becomes possible to give all secondary users a more equal status, facilitating resource sharing. A transmitter is provided with an identifier inserter (25) for providing the identifier (11) in a transmitted radio signal. In a corresponding manner, a receiver is provided with identifier detector (29) for detecting a presence of the identifier in a received signal.

摘要： The invention comprises a method and a corresponding apparatus (53). A candidate set of sensors that are available to participate in an occasion of cooperative spectrum sensing is obtained. For each sensor in the candidate set, its radial distance to a central coordinating node in a communication system is also obtained (73). A sequence of minimum radii is produced (75,79). For each minimum radius in the sequence, an accommodation number is determined (75,87). The accommodation number associated with a minimum radius is the greatest number of sensors that can be placed on circle having this radius without a probability that all these sensors are mutually uncorrelated falling below a design probability threshold. Sensors from the candidate set are then selectively added (91,95) to an active set of sensors based on the minimum radii, the corresponding accommodation numbers and the obtained radial distances.

摘要： Embodiments herein relate to a first communication device (122, 124) and method therein for enabling interference management of data transmissions from a second communication device (110) to a third communication device (121) in a wireless communications network (100). Furthermore, embodiments herein also relates to a second communication device (110) and method therein for enabling interference management of data transmissions from the second communication device (110) to a third communication device (121) in a wireless communications network (100). First, the second communication device (110) transmits information relating to a request for a first set of radio resources of a radio channel for a first data transmission to the third communication device (121). Then, this information relating to a request for radio resources of a radio channel for a first data transmission from the second communication device (110) to the third communication device (121) is received by the first communication device (122, 124). In response thereto, the first communication device (122, 124) transmits an interference notification to the second communication device (110) when the received information relating to a request for radio resources of the radio channel is determined to conflict with requested radio resources of the radio channel for a second data transmission to or from the first communication device (122, 124). Thus, the second communication device (110) receives at least one interference notification from at least one first communication device (122, 124) indicating that its transmitted information relating to a request for radio resources of the radio channel has been determined to conflict with requested radio resources of the radio channel for at least one second data transmission to or from the at least one first communication device (122, 124).

摘要： Methods, apparatuses, and computer program products provide for routing information between nodes of a radio network. A quality metric is received at a network node that indicates a quality of at least one channel of a plurality of channels in the network. A virtual network is generated that includes one or more routes between a source node and a destination node. A modified virtual network is generated based at least in part on the quality metric and the virtual network, and is then used to determine an optimized route between the source node and destination node. The determination includes a joint selection of one or more of a plurality of network nodes and the plurality of the channels.
