Abstract: 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.

Abstract: 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.

Abstract: A position of a device within a cluster of multiple devices is determined and stored in a memory. An uplink radio resource is mapped from a downlink radio resource in dependence on the determined position of the device within the cluster of multiple devices. In an embodiment the respective uplink and downlink radio resource is a PUCCH and PDCCH of a cellular network, and the cluster is a D2D network. In one embodiment the device position is an index j which is used to offset from a predetermined mapping pattern. In another embodiment the position of the device corresponds to an individual field of a transmission on the PDCCH and the mapping is in dependence on a bit value in the individual field.

Abstract: There is stored in a memory an association between each nth one of N content types with a respective nth group of N groups of identifiers (N is an integer greater than one, n indexes from 1 to N, and at least one of the groups has more than one identifier). A beacon sender selects one of the content types for a beacon to be transmitted and selects a beacon identifier from the group associated with the selected content type. The beacon to be transmitted is compiled to include content of the selected content type and the selected beacon identifier. The beacon receiver selects at least one of the content types; and for a plurality of beacons received, filters out from further processing each beacon having a beacon identifier that is not within the group of identifiers associated with any of the at least one selected content types. The network creates the association and broadcasts it in a network cell.

Abstract: An apparatus is disclosed that performs operations including determining whether an application message meets a predetermined set of criteria. If the application message meets the set, the application message is transmitted via a first communication layer pathway between the apparatus and one or more other apparatuses participating in a device-to-device communication with the apparatus. If the application message does not meet the set, the application message is transmitted via a second communication layer pathway between the apparatus and the other apparatus. The first and second communication layer pathways are different. The first pathway may be an L1 physical control channel while the second pathway may be an L1 physical data channel. The first pathway may be a first L2 logical channel while the second pathway may be a second L2 logical channel. Methods and program products are also disclosed.

Abstract: In an exemplary embodiment there are determined which radio resource are to be used for contention based access, and the allocated radio resource is accessed according to a probability function that varies in dependence on at least one of interference measured on the allocated radio resource and a received power level for the allocated radio resource. By example the radio resource is allocated by a cellular base station for use in D2D communications; the base station provides configuration parameters for the D2D communications via common or dedicated signaling; the received power level is a target received power level that is received via broadcast system information or dedicated control signaling; and/or the received power level is itself a function of pathloss on a wireless link to the cellular base station. Embodiments are presented for method, apparatus, and tangibly stored computer program.

Abstract: At a cluster head/first device there is received, from each of at least two other devices with which the cluster head has a respective wireless link, a quality indicator for the respective link observed by the respective other device. The cluster head compiles those received quality indicators into a compressed report, and sends the compressed report to a network entity. In a specific embodiment the cluster head also determines an additional quality indicator of each of those respective links observed by the cluster head by listening to a sounding reference signal sent by the respective other device to the network entity on a PUCCH. Those additional quality indicators are also compiled into the compressed report, as are further quality indicators received from the devices for D2D links between pairs of those other devices that exclude the cluster head. The compressed report can inform how many indicators are above/below a threshold.
