The invention relates to a wireless communication system comprising a plurality of radio devices. Each radio device of the plurality of radio devices is configured to: obtain timing information representing timing schedules of one or more other radio devices within its neighborhood; define, based on the obtained timing information, at least one timing schedule group into which the plurality of radio devices are divided and a size of each at least one timing schedule group; and synchronize its own timing schedule with the timing schedule of the timing schedule group with the largest size. The invention relates also to a synchronization method () for the wireless communication system, a radio device for a wireless communication system, and a synchronization method for the radio device.

Decentralized synchronization solution for wireless communication networks

Methods and apparatus, including computer program products, are provided for communications. In one aspect there is provided a method. The method may include sending, by a low power node, an indicator to a target low power router, wherein the indicator at least represents a request to operate with a prior context used at a source low power router; and receiving, by the low power node, a message in response to the indicator, wherein the message at least indicates whether the low power node can operate at the target low power router with a same context that corresponds to the prior context used previously at the source low power router. Related apparatus, systems, methods, and articles are also described.

Session continuity for IPv6 over Bluetooth low energy

A method and apparatus are disclosed for recording, at a recording apparatus, video content obtained from an array of cameras, wherein each camera records video content from a section of a recording area; receiving a wireless message from a tag situated in the recording area; applying a time stamp to the received wireless message; determining directional information of the tag in the recording area based on analysis of the wireless message; and causing the directional information and the timestamp to be stored.

Video recording method and apparatus

Disclosed in this specification is a method comprising inserting an anti-whitened data portion into a data packet that is to be whitened by whitening to yield a whitened data packet for transmission () from a first radio communications apparatus () to a second radio communications apparatus (), the anti-whitened data portion having been determined based on anti-whitening data received () from the second radio communications apparatus () at the first radio communications apparatus, wherein the anti-whitened data portion is obtainable from a specific data block by anti-whitening, the anti-whitening compensating for the whitening so that the whitened data packet comprises the specific data block in non-whitened form.

Data package preparation

A method and apparatus are disclosed for detecting a user selection of a positioning tag; retrieving directional information and timestamp information relating to the selected tag; comparing directional information relating to the selected tag with directional information of an array of cameras arranged to capture video content from a recording area; identifying video content captured by one or more cameras from an array of cameras arranged to capture video content from a recording area, wherein the video content captured by the one or more cameras is identified if the one or more cameras have captured video content from a section of the recording area relevant to the location of the selected tag over a time period relevant to the timestamp information relating to the selected tag; and selecting the identified video content obtained from the one or more cameras for display.

Video content selection

A method and apparatus are provided for facilitating remote participance in a community. A method may include causing an anchor terminal located at a first location to use a proximity-based wireless communication technology to participate in an ad hoc community formed at least in part by the anchor terminal and one or more further terminals at the first location using the proximity-based wireless communication technology to communicate with each other. The method may further include causing the anchor terminal to maintain a connection to a structured network, thereby enabling a remote terminal to participate in the community. The method may additionally include, in an instance in which the remote terminal participates in the community, causing the anchor terminal to serve as a gateway between the terminals participating in the community at the first location and the remote terminal. A corresponding apparatus is also provided.

Methods and apparatuses are provided for providing adaptive user notifications. A method may include detecting an event. The method may further include determining usage of one or more connected apparatuses. The method may also include determining, based on the determined usage, a notification method for notifying of the event. The method may additionally include generating an event notification message based on the determined notification method. The method may further include causing the event notification message to be sent to a connected apparatus to trigger the connected apparatus to provide an alert indicative of the event in accordance with the determined notification method. Corresponding apparatuses are also provided.

Systems, methods, and apparatuses for providing adaptive user notifications

A method of configuring an audio system comprising one or more speaker units, comprises: transmitting radio signals from at least a first location indicating a first speaker unit position, and from a second location indicating a second speaker unit position or a user position; receiving the signals at an antenna of the audio system; calculating an angle of arrival of the signals at the antenna; calculating the relative positions of the first and second locations based at least partially on the angle of arrival; and configuring the audio system based on the relative positions of the first and second locations.

Configuring a sound system

Apparatus comprises: a multi-element antenna; and a transmitter configured to broadcasting multiple packets from the multi-element antenna, wherein each packet comprising: a positioning part; and a calibration data part, wherein the calibration data part of a packet comprises: a portion of calibration data; and data indicating a location of the portion of calibration data in a set of calibration data.
