Abstract
A communications device that, when in an inactive state, transmits a first signal comprising a random access preamble and a first portion of data to infrastructure equipment, receives a random access response message from the infrastructure equipment, and transmits a second signal comprising a second portion of the data to the infrastructure equipment.
Claims14
A communications device for transmitting data to or receiving data from a wireless communications network, the communications device comprising
- transmitter circuitry configured to transmit signals to one or more infrastructure equipment of the wireless communications network via a wireless access interface provided by the one or more infrastructure equipment,
- receiver circuitry configured to receive signals from one or more of the infrastructure equipment via the wireless access interface, and
- controller circuitry configured to control the transmitter circuitry and the receiver circuitry to transmit or to receive the signals representing data, wherein when the communications device is in an inactive state, the controller circuitry is configured in combination with the receiver circuitry and the transmitter circuitry
- to transmit a first signal comprising a random access preamble and a first portion of data to one of the infrastructure equipment,
- to receive a random access response message from the infrastructure equipment, and
- to transmit a second signal comprising a second portion of the data to the infrastructure equipment.
A method of operating a communications device in an inactive state for transmitting data to or receiving data from a wireless communications network, the method comprising
- transmitting a first signal via a wireless access interface provided by an infrastructure equipment of the wireless communications network, the first signal comprising a random access preamble and a first portion of data to the infrastructure equipment,
- receiving a random access response message from the infrastructure equipment, and
- transmitting a second signal comprising a second portion of the data to the infrastructure equipment.
-15. (canceled)
An infrastructure equipment for transmitting data to or receiving data from a communications device, the infrastructure equipment forming part of a wireless communications network and comprising
- transmitter circuitry configured to transmit signals to the communications device via a wireless access interface provided by the wireless communications network,
- receiver circuitry configured to receive signals from the communications device via the wireless access interface, and
- controller circuitry configured to control the transmitter circuitry and the receiver circuitry to transmit or to receive the signals representing data, wherein when the communications device is in an inactive state, the controller circuitry is configured in combination with the receiver circuitry and the transmitter circuitry
- to receive a first signal comprising a random access preamble and a first portion of data from the communications device,
- to transmit a random access response message to the communications device, and
- to receive a second signal comprising a second portion of the data from the communications device.
