Method and apparatus for transmitting and receiving data

A technique for transmitting and receiving data () on shared radio spectrum according to a listen after talk, LAT, procedure is described. As to a transmitting aspect of the technique, one or more parameters of the LAT procedure are set. At least one of the one or more parameters () is set depending on at least one of a Quality of Service, QoS, requirement of the data and a state of the shared radio spectrum. The data () is transmitted on the shared radio spectrum according to the LAT procedure using the one or more parameters.

Technique for listening after talk

A method of transmission scheduling for one or more process devices in an industrial application, such as a sensor, an actuator and/or a process controller, capable of wireless communication, implemented by a radio control unit, is proposed, the method comprising: determining with respect to the industrial application whether a licensed shared access spectrum is available and assigning to the one or more process devices, based on a traffic type of the data to be transmitted by the one or more process devices, an access spectrum within the licensed shared access spectrum.

Access spectrum assignment

In one aspect, a transmitter, for a first time interval, allocates first and second portions of a frequency band to first and second multicarrier modulation schemes with first and second subcarrier spacings that differ from one another. The data is transmitted to wireless devices in the first time interval using the first and second multicarrier modulation schemes in the first and second portions of the frequency band. For a second time interval, third and fourth non-overlapping portions of a frequency band are allocated to third and fourth multicarrier modulation schemes that have third and fourth subcarrier spacings that differ from one another. The third and fourth portions and/or schemes differ from the first and second portions and/or schemes. The data is transmitted in the second time interval using the third and fourth multicarrier modulation schemes in the third and fourth portions of the frequency band.

Dynamic selection of multicarrier mode based on QoS parameters

A method to operate an access node of a wireless communication network is provided. A first frame may be provided including a first header and a first data block with first data for a first wireless terminal and a second wireless terminal. The header may include a first control field indicating a first idle period resource and a second control field indicating a second idle period resource, and the first and second idle period resources may be different. Transmission of the first frame to the first and second wireless terminals may be initiated. Responsive to receiving a notification message using the first idle period resource, a second frame may be provided including a second header and a second data block with second data for the second wireless terminal. Transmission of the second frame to the second wireless terminal may be initiated while deferring transmission to the first wireless terminal.

Methods supporting multicast/multiuser transmission using listen after talk and related network nodes

A technique for communicating protocol data units, PDUs, in a radio communication from a transmitter () to a receiver () is described. As to a method aspect of the technique, one or more control messages indicative of Quality of Service, QoS, requirements for the radio communication are received. The QoS requirements include a control command for a reliability of the radio communication and a control command for a latency of the radio communication. A batch of redundant PDUs is transmitted from the transmitter () to the receiver (). A number of the redundant PDUs per batch depends on the control command for the reliability and a temporal spread of the redundant PDUs per batch depends on the control command for the latency.

Radio communication of critical packet data units

Methods and apparatuses are provided for controlling a listen-after-talk (LAT) procedure in a wireless communication network comprising at least a source node (SN) and a destination node (DN). Such methods or apparatuses may obtain information indicating an operational context of the LAT procedure, adapt at least one parameter of the LAT procedure according to the obtained information, and control at least the SN or the DN to communicate according to the LAT procedure having the adapted at least one parameter.
