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： 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 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. 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 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 perform their transmissions in accordance with the received rules.

摘要： A local radio access information transmitter for use in a communications area serviced by multiple different radio access technologies (RATs) allocated to different radio resources in different locations in the communications area. Each RAT is associated with one or more RAT radio transceivers for serving user equipments (UEs) at least in some portion of the communications area using one of the multiple RATs. The local radio access information transmitter is in addition to the RAT radio transceivers and located near an associated hotspot service area at least partly inside the communications area. The local radio access information transmitter determines local radio access information including one or more different RATs available for UE service in the hotspot service area and a frequency of frequencies of operation allocated to each RAT in the hotspot service area, sends a registration message to a wide area radio access information controller, and based on a response from the wide area radio access information controller, determines what radio resources to use to transmit the local radio access information signals. Radio transmission circuitry transmits the local radio access information signals for receipt by UEs in the hotspot service area using the determined radio resources.

摘要： A method and an arrangement (400) for determining an admission control threshold for use in an admission control procedure are provided. The admission control procedure manages a first spectrum resource (R1). The first spectrum resource (R1) has a first spectrum resource capacity and a first available spectrum resource capacity, wherein the first available spectrum resource capacity has a time dependence. In a step (220), the admission control threshold is determined based on the first spectrum resource capacity and a measure of the time dependence of the first available spectrum resource capacity.

摘要： The invention presents methods and corresponding device relating to cooperative spectrum sensing. First a candidate set of sensors that can participate in an occasion of cooperative spectrum sensing is obtained. A cost formula for calculating a cost associated with using sensors from the candidate set in the cooperative spectrum sensing is then defined (75; 107, 97). The candidate set is partitioned (29; 14, 145) into an active set and a passive set. The active set contains any sensor (s) from the candidate that is to participate in the cooperative spectrum sensing. The passive set includes any sensor (s) that is not to participate in the cooperative spectrum sensing. The partitioning of the candidate set is done by applying an optimization procedure (79, 81, 83; 111, 113, 115) which performs a constrained optimization of the cost in accordance with the defined cost formula.

摘要： The invention presents methods and corresponding devices for improving cooperative spectrum initiating sensing. A device (61;61.1) first receives an invitation (17;35) to participate in cooperative spectrum sensing. The device performs an autonomous decision (19) on whether or not to participate in the cooperative spectrum sensing in response to the invitation. If it is determined to participate in the cooperative spectrum sensing to which the invitation relates, spectrum sensing is then performed (21;45). With the invention, sensor selection becomes “distributed”, i.e. it is up to the device itself to decide on participation in the cooperative sensing, rather than having, for example, a central entity determining what devices should act as sensors in the cooperative spectrum sensing. One advantage is that the amount of signalling required for sensor selection can be kept at a minimum, thereby saving communication resources.
