The example embodiments of the present disclosure relate to a device, method, apparatus and computer-readable storage medium for communication. A method for communication comprises: generating unavailability information by a first device, wherein the unavailability information comprises at least an indication that the first device is unavailable for communication on a predetermined frequency band during a predetermined time period, an identifier of the first device, and a reason associated with the unavailability information; and sending the unavailability information to a second device in a predetermined frame structure.

Embodiments of the present disclosure relate to a trigger for a retransmission. In an aspect, a terminal device performs a method comprising: method comprising: performing, at a terminal device, an initial transmission for a protocol data unit, PDU, in a radio link control, RLC, layer to a network device; and triggering a retransmission, at the terminal device, for the PDU in the RLC to the network device when submitting the initial transmission for the PDU from the RLC layer to a medium access control, MAC, layer, based on a discard timer associated with the PDU in a packet data convergence protocol layer, PDCP, being below a threshold when submitting the initial transmission for the PDU from the RLC layer to the MAC layer.

There is provided, an apparatus for a first entity, the apparatus comprising: means for receiving, from a second entity, a first message comprising information indicating a scope of one or more header extensions that are supported by the second entity; means for sending, to the second entity, a subscription request to subscribe to one or more tracks and requesting one or more header extensions for the one or more tracks, the requested one or more header extensions being based at least in part on the first message; means for receiving, from the second entity, a subscription response indicating one or more header extensions that will be provided for the one or more tracks; and means for sending, to a third entity, an indication of the one or more header extensions that will be provided for the one or more tracks.

There is provided, a first entity comprising: means for sending, to a second entity, a first message comprising information indicating a first scope of one or more first header extensions that are supported by the first entity; means for receiving, from the second entity, a second message comprising information indicating a second scope of one or more second header extensions that are supported by the second entity; means for sending, to the second entity, a request to subscribe to one or more tracks; and means for receiving, from the second entity, one or more objects for the one or more tracks based on the request, wherein the one or more objects comprise at least one of the one or more first header extensions or the one or more second header extensions based on the first scope and the second scope.

There is provided, a first entity comprising: means for receiving, from a second entity, information indicating one or more tracks and information indicating one or more header extensions associated with the one or more tracks; means for sending, to the second entity, a request to subscribe to at least one of the one or more tracks; and means for receiving, from the second entity, one or more objects for the one or more tracks based on the request, the one or more objects comprising at least one of the one or more header extensions.

The present subject matter relates to a method comprising providing an antenna array comprising a plurality of radiators, each radiator being configured to convey a radio frequency signal; and using a pair of digital control signals to selectively activate a weighting of the radio frequency signal associated with the radiator, in accordance with a defined weighting level.

Described herein is a device for obtaining features relating to a higher-level entity and a plurality of lower-level entities included in the higher-level entity, wherein the lower-level entities are configured to communicate with each other to together provide a higher-level function performed by the higher-level entity, the device comprising: an input module configured to receive, from the plurality of lower-level entities, lower-level extracted features relating to the plurality of lower-level entities; and a feature extraction module configured to obtain higher-level extracted features relating to the higher-level entity and the plurality of lower-level entities based on the received lower-level extracted features, wherein the higher-level extracted features comprise: for each lower-level entity: at least one higher-level extracted feature for the each lower-level entity, representing a state of the each lower-level entity when communicating with the remaining lower-level entities, and at least one higher-level extracted feature for a relation between the each lower-level entity and the remaining lower-level entities, representing a state of the communication between the lower-level entities; for all lower-level entities: at least one higher-level extracted feature for a relation between the higher-level entity and all lower-level entities, representing a state of all lower-level entities when communicating with each other to together provide said function performed by the higher-level entity, wherein the device further comprises an output module configured to output the obtained higher-level extracted features.

Embodiments of the present disclosure relate to transmission opportunity sharing through frequency domain splitting. An apparatus determines a sub-bandwidth portion of a bandwidth allocated to a second access point (AP) device for accessing a transmission opportunity (TxOP) associated with a first AP device. The apparatus is associated with the second AP device, and the bandwidth is associated with the TxOP. The apparatus communicates with the second AP device on the sub-bandwidth portion.

Disclosed is a method comprising determining whether one or more conditions are fulfilled for skipping reading of one or more mobility-related system information broadcast messages on a cell of a non-terrestrial network; and based on determining whether the one or more conditions are fulfilled, determining whether to skip the reading of the one or more mobility-related system information broadcast messages on the cell of the non-terrestrial network.

In some embodiments, there may be provided a method including receiving, by a machine learning model, channel state information for at least one radio frequency signal; generating, by the machine learning model, a prediction generated using at least the channel state information for the at least one radio frequency signal, wherein the prediction indicates one or more objects causing blockage to the at least one radio frequency signal; modifying, based on the prediction of the one or more objects, a path loss model used to determine a distance between a receiver and a transmitter of the at least one radio frequency signal; and determining, based on the modified path loss model, at least a distance between the receiver and the transmitter. Related systems, methods, and articles of manufacture are also disclosed.
