A radio station, in particular an access point, for client localization in a multipath indoor environment is disclosed. The radio station comprises: a circular antenna array comprising uniform circularly arranged antenna elements; and a processor configured to: transform first input data from the circular antenna array into second input data using a transform that transforms the first steering vector of the circular antenna array into a second steering vector of a virtual linear antenna array; and transform the second input data into third input data by using a transform that transforms the second steering vector of the virtual linear antenna array into a third steering vector of a second virtual linear antenna array, comprising a larger number of antenna elements than the virtual linear antenna array; and determine an angle of arrival based on the third input data.

Radio station for client localization in multipath indoor environment

A device resolves a collision between its transmission and a simultaneous transmission of another device. The device is configured to interrupt its transmission, determine a negotiation signal, and determine at least one available resource to occupy with the negotiation signal during a negotiation period. Further, the device is configured to transmit the negotiation signal on the at least one available resource and simultaneously receive a negotiation signal on another resource from at least one other device during the negotiation period. Then, the device is configured to decide, based on all negotiation signals, whether to retransmit the interrupted transmission after the negotiation period.

Device and method for fast collision resolution

A device on a wireless network generates duration data for determining a duration of a time interval. A transmission is then instructed, by the device, to transmit the duration data and a downlink payload including an aggregated Media Access Control (MAC) layer data unit, the downlink payload being transmitted on first subcarriers. The transmission also includes a trigger that configures the at least one other device on the network to transmit an uplink payload within the time interval, and during at least part of the transmission of the downlink payload, on second subcarriers that are at different frequencies to the first subcarriers.

Frequency division duplex device and method for use in a wireless network

An apparatus and method for communications, wherein a communication device comprises a processor configured to perform during a time period a determination if a transmission medium is free for communication, and a transmitter configured to transmit a wake-up signal on the transmission medium if the transmission medium is free.

Apparatus and method for communications

The disclosure relates to an access point device (AP) for communicating with a client device (STA). The AP may include a transceiver configured to transmit a first data packet indicating a set of groups, wherein each group of the set of groups is associated with a specific set of transmission parameters. The transceiver of the AP may also be configured to transmit a second data packet indicating an allocation for at least part of the groups. Furthermore, the transceiver of the AP may also be configured to receive a response frame using at least part of random access (RA) resources selected by the STA for the at least part of the groups.

Access point device (AP) and client device (STA) using grouping of transmission parameters

The application relates to an access point type communication device () configured to allocate a plurality of random access resources to a set of associated client type communication devices (-). The access point type communication device () comprises a controller () configured to maintain a set of association identifiers, wherein each identifier of the set of association identifiers is configured to identify a respective client type communication device of the set of client type communication devices (-), as well as a set of random access identifiers. In an embodiment, the access point type communication device () further comprises an allocator () configured to allocate the plurality of random access resources to the set of client type communication devices (-) on the basis of the set of random access identifiers.

Random access mechanism for access point and station in a wireless communication network

A device for assigning radio channels to radio transceiver devices. The device comprises an interface configured to receive two or more radio communication values, each associated with a radio transceiver device. The device comprises a processor configured to calculate an ordering of two or more radio transceiver devices based on radio communication values and build, according to the ordering, one or more rooted tree representing assignment of available radio channels to first radio transceiver devices according to the ordering. A branch of the rooted tree is selected according to a cost function value calculated along each branch. The processor is configured to assign the available radio channels to the radio transceiver devices according to the selected branch.

Advanced dynamic channel assignment

An apparatus and a method for providing an efficient multi-client access in a WLAN, the method comprising the step of: when the number of clients exceeds a threshold, creating at least two virtual access points (VAP, VAP, VAP); load balancing by distributing workloads across the created at least two virtual access points; and dynamically allocating at least one quality of service parameter (e.g., timeslots, AIFS, TXOP, maximum and minimum contention window) to each of the created at least two virtual access points.
