The present invention relates to a method for obtaining a location using Neighbor Awareness Networking, NAN, and a corresponding system as well as a method carried out by a NAN device and a corresponding NAN device so that a location can be obtained in a simple way. In particular, the method for obtaining a location using neighbor awareness networking, NAN, comprises requesting the location of a target NAN device; determining a cluster of wireless NAN devices comprising the target NAN device as well as one or more anchor NAN devices having predetermined locations to serve as positioning nodes; performing range measurements using the travel times of radio signals between the target NAN device and each of the one or more anchor NAN devices; and obtaining the location of the target NAN device based on the range measurements.

A method, performed by an EAP authenticator in a communication network, is disclosed. An identification of at least one EAP method supported by an EAP authentication server providing an EAP authentication service to the EAP authenticator is obtained, wherein the identification is obtained from a network entity of the communication network or from inspection of traffic through the EAP authenticator. The identification of at least one EAP method is provided to a device operable to request communication network access from the EAP authenticator. Also disclosed is a method, performed in an EAP authentication server in a communication network. A request for identification of EAP methods supported by the EAP authentication server is received, and a response to the request is sent identifying at least one EAP method supported by the EAP authentication server. An EAP authenticator, EAP authentication server and computer program are also disclosed.

Method and apparatus for extensible authentication protocol

A method and an access node of a wireless network, for controlling uplink transmissions from wireless devices. It is detected that both a Narrow Band wireless device capable of receiving signals on a first narrow bandwidth channel and one or more legacy wireless devices capable of receiving signals on a second broad bandwidth channel are present. The second broad channel covers the first narrow channel. When receiving an uplink transmission from the Narrow Band device that indicates pending uplink data, the access node performs a downlink transmission that both Narrow Band wireless devices and legacy wireless devices can receive and decode. The downlink transmission indicates that the Narrow Band wireless device is allowed to transmit its pending uplink data on allocated resources within the first bandwidth channel, and that the second bandwidth channel is occupied.

A method and an access node for communicating in a wireless communication network, the method comprising at an access node obtaining a timing indicator; transmitting to at least one communication device a first frame sequence. The first frame sequence comprises a first portion comprising a first preamble associated with a first communication protocol, a second portion comprising a first polling frame associated with the first communication protocol, and a third portion comprising a second preamble followed by a second polling frame, the second preamble and second polling frame are associated with a second communication protocol. The third portion is multiplexed in the frequency domain with the second portion. The method further comprises providing to the at least one communication device the timing indicator for enabling the access node to control a time of reception of a first portion of a subsequent second frame sequence.

Apparatuses and methods for communicating in a wireless communication network

A control entity in a wireless communications system obtains discontinuous reception information for a plurality of wireless terminals and configures one or more of said wireless terminals, based on the obtained discontinuous reception information, to harmonise the awake periods of the plurality of wireless terminals. The control entity determines a common reception period for the plurality of wireless terminals such that a broadcast or multicast transmission during the common reception period is received simultaneously by the wireless terminals.

The application relates to a method for operating a first wireless device () in a wireless network. At least one target wireless device () is determined which should receive a wake up signal by which a wake up receiver of the at least one target wireless device is informed that a main transceiver of the target wireless device should be ready for receiving at least a first message from the first wireless device, Furthermore a frequency is determined at which the at least first message should be transmitted to the at least one target wireless device, and a frequency information is encoded into the wake up signal with which at least one target wireless device is informed about the frequency at which the at least first message will be received. The wake up signal is transmitted with the encoded frequency information to the at least one target wireless device.

There is provided mechanisms for handling acknowledgements from nodes in a wireless radio ad-hoc network. A method is performed by a gateway of the wireless radio ad-hoc network. The method comprises transmitting radio signalling to nodes in the wireless radio ad-hoc network. The transmitted radio signalling is addressed to, and requiring acknowledgement from, at least one node in the wireless radio ad-hoc network. The method comprises receiving radio signalling from a node in the wireless radio ad-hoc network. The received radio signalling comprises one in-packet Bloom Filter comprising acknowledgement of the transmitted radio signalling from at least one of the nodes.

A first communications device () and a method therein for Device-to-Device (D2D) communication with a second communications device () using a first Radio Access Technology (RAT) or a second RAT. The first and second communications devices are operating in a communications network (). The first communications device transmits 5 the second communications device, by means of the first RAT, information relating to a proximity service provided by the second RAT. Thereby the information enables the second communications device to determine whether to use the first RAT or the proximity service provided by the second for D2D communication with the first communications device.

The present disclosure relates to methods and arrangements for protecting the integrity of subscribers to personal area networks. This object is obtained by a method, performed in a service subscribing node of a personal area network, for discovering a service providing node. The method comprises obtaining a service identity resolving key. A discovery signal is received from a service publishing node, and a service identifier of the service providing node is determined from a service identity comprised in the received discovery signal using the service identity resolving key.

A mobile device that comprises a main receiver and a wake-up receiver is operated by periodically attempting to receive a first signal that is configured for receipt by the wake-up receiver. For each attempt, a detection result is generated that indicates whether the first signal was received with a signal quality that satisfies a predetermined minimum quality criterion. One or more of the detection results are used as a basis for deciding whether or not the wake-up receiver is within range of an access point. An operation of the mobile device is adjusted in response to a decision that the wake-up receiver is not within range of the access point.

Detection and operation of wake-up receivers with limited range

An access point of a radio network, a wireless device and methods therein, for controlling a radio communication of data from the access point to the wireless device. When detecting that the number of wireless devices in a user group for which downlink data is pending exceeds the number of wireless devices that can receive downlink data during an upcoming time period reserved for the user group, the access point selects a subset of the wireless devices to which it is possible to send downlink data during the upcoming time period, and transmits a beacon indicating that the subset of the wireless devices have pending data to receive. Thereby, any unsuccessful requests transmitted from devices for pending data may be avoided and the risk for collision of requests may also be reduced.
