Abstract
A communications device comprising circuitry configured to receive an indication of an allocation of physical resources of a wireless access interface providing plurality of different physical channels of different types, each of the different types of physical channels being defined for transmitting messages in accordance with a different priority level using a contentious access technique. The circuitry configured to identify a relative priority for transmitting one or more messages, select one of the physical channels in accordance with the identified relative priority, and transmit the message via the select physical channel.
Claims22
A communications device for transmitting a message to an infrastructure equipment of a mobile communications network, the communications device comprising
- a transmitter configured to transmit signals via a wireless access interface provided by the infrastructure equipment,
- a receiver configured to receive signals from the infrastructure equipment via the wireless access interface, and
- a controller configured to control the transmitter and the receiver to transmit and/or receive the signals, the controller being configured with the receiver
- to receive an indication of an allocation of physical resources of the wireless access interface providing plurality of different physical channels of different types, each of the different types of physical channels being defined for transmitting messages in accordance with a different priority level using a contentious access technique, the allocation of the physical resources being dependent upon the priority of the message and the contentious access technique, and the controller is configured with the transmitter
- to identify a relative priority for transmitting one or more of the messages to the infrastructure equipment,
- to select one of the physical channels in accordance with the identified relative priority, and
- to transmit the message via the select physical channel, wherein the message is transmitted via the selected physical channel in accordance with the contentious access technique determined for the selected physical channel provided by the received indication.
Infrastructure equipment for use with a mobile communications network, the infrastructure equipment comprising:
- a transmitter configured to transmit signals to one or more communications devices via a wireless access interface,
- a receiver configured to receive signals from the one or more communications devices via the wireless access interface, and
- a controller configured to control the transmitter and the receiver to transmit and/or receive the signals, the controller being configured
- to determine an allocation of physical resources of the wireless access interface providing a plurality of different physical channels of different types, each of the different types of physical channels being defined for transmitting messages in accordance with a different priority level using a contentious access technique, the allocation of the physical resources being dependent upon the priority of the message and the contentious access technique, and the controller is configured with the transmitter
- to transmit an indication of the determined allocation of physical resources of the wireless access interface to the one or more communications devices via the wireless access interface.
20-24. (canceled)
A method of controlling a communications device for transmitting a message to an infrastructure equipment of a mobile communications network, the method comprising:
- controlling the receiver to receive from the infrastructure equipment via a wireless access interface provided by the infrastructure equipment, an indication of an allocation of physical resources of the wireless access interface providing plurality of different physical channels of different types, each of the different types of physical channels being defined for transmitting messages in accordance with a different priority level using a contentious access technique, the allocation of the physical resources being dependent upon the priority of the message and the contentious access technique,
- identifying a relative priority for transmitting one or more of the messages to the infrastructure equipment,
- selecting one of the physical channels in accordance with the identified relative priority, and
- controlling a transmitter to transmit the message via the select physical channel, wherein the message is transmitted via the selected physical channel in accordance with the contentious access technique determined for the selected physical channel provided by the received indication.
