摘要： An apparatus receives from a first device a first broadcast message/beacon which comprises an identifier for an enabling station, then uses the identifier to associate with the enabling station to obtain from it a list of at least one license-exempt channel (e.g., TV whitespaces). In one embodiment the apparatus can then join an ad hoc network (IBSS) with the first device and transmit a second beacon which comprises the identifier for the enabling station. If the apparatus hears multiple beacons advertising different IBSSs, it can select to join the first device's ad hoc network over the other(s) based on a service offered or the first device's network being trusted. Various examples are detailed for where in the beacon frame the identifier (e.g., SSID) might be placed. In one example the apparatus and first device are Mode I devices and the enabling station is a Mode II device under (draft) IEEE802.11af.

摘要： A method, apparatus and computer program product provide improved detection of overlapping wireless networks. In this regard, the method, apparatus and computer program product may utilize a processor, such as a processor on a wireless access point, to determine one or more parameters for a scan of a wireless network to identify overlapping networks. Wireless stations may utilize the parameters to determine the content of a scan report generated from a scan of the wireless network. The wireless stations may further utilize the parameters to determine which values should be monitored and/or recorded during the scan of the network. The wireless stations may respond to the access point with results corresponding to the parameters requested by the access point, and the access point may use the results to determine channel access parameters for other devices on the network, such as the wireless stations.

摘要： A fixed or Mode II device enables a Mode I device for license exempt operation by providing to it a list of available license exempt radio channels and a parameter indicating an interval at which contact verification signals CVSs are to be sent. The CVSs verify whether the list remains valid. The fixed/Mode II device then repeatedly sends contact verification signals spaced in time from one another according to the interval. In various embodiments the parameter may be an explicit indication (number of seconds or number of beacons between consecutive CVSs), or it may be implicit (derived from an ID of the fixed/Mode II or Mode I device or a frequency channel, in which the relevant ID is the parameter). A plurality of enabled Mode I devices each gets a device-specific list, and in one embodiment the interval is the same for each of them and the explicit indication is broadcast while in another the parameter is provided to each of them via unicast messages and the interval may differ.

摘要： A wireless backhaul link is established by sending from a mobile first access node to a second access node a priority request message requesting high priority for a link between them. The established wireless backhaul link is utilized as part of a wireless multihop connection between the second access node and at least one user device attached to the mobile first access node. In various embodiments the high priority is requested by indicating a priority class (e.g., highest priority, at least higher than any current priority, and at least as high as a highest current priority) and may also indicate how many user devices are attached and/or an amount of data waiting to be sent. A first timer may be initiated upon inactivity on the wireless backhaul link and continuous inactivity through expiry of that automatically results in a reduction of the priority class for the wireless backhaul link.

摘要： Downlink common control information communicated in a first network (such as a macro network or a small cell) between a first/macro access node and a user equipment UE is mapped to an uplink resource. The first/macro access node and UE then tune to the mapped uplink resource to send or receive dedicated control information about the UE concerning a second network (an underlay network such as a femto CSG or D2D network). In one embodiment the DCI may be within a downlink assignment indicated by P-RNTI, RA-RNTI, or SI-RNTI; and the mapping uses a control channel element which carries the P-RNTI or the RA-RNTI or the SI-RNTI. In another the mapped uplink resource is a format 1a or format 1b PUCCH and the common control information requires neither an acknowledgement nor a negative acknowledgement. The dedicated control information may inform about interference experienced by the UE with the second network.

摘要： A feedback radio resource in a license-exempt frequency band maps from a data radio resource to at least one frequency sub-band which the data resource excludes. The feedback resource is also spaced in time from the data resource by a predetermined interval. Feedback (ACK/NACK) for data received in the data resource is then sent in the feedback resource. In various embodiments the sub-band is one or more edges of the data resource channel, or of a license-exempt component carrier. The predetermined interval may be a function of how much of the data resource is occupied by data. The data transmitting device delays sending its data by a time offset from the end of a previous transmission on that channel, or if it does not know the end time it delays until the predetermined interval plus the length of the feedback resource have lapsed. Various synchronization aspects are also disclosed.
