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.
Claims18
A method of operating an infrastructure equipment providing a wireless access interface for transmitting data to or receiving data from a communications device in an inactive state, the method comprising:
- receiving a first signal via the wireless access interface, the first signal including a random access preamble and a first portion of data from the communications device;
- transmitting a random access response message to the communications device;
- and
- receiving a second signal comprising a second portion of the data from the communications device;
- and
- transmitting, based on whether the infrastructure equipment successfully receives the second portion, an acknowledgement or a negative acknowledgement (ACK/NACK) to the communications device.
Circuitry for an infrastructure equipment, the circuitry comprising:
- transmitter circuitry;
- receiver circuitry;
- and
- control circuitry configured to control the transmitter circuitry and the receiver circuitry to:
- provide a wireless access interface;
- operate in an active state by controlling the transmitter circuitry and the receiver circuitry to transmit or receive signals representing data via the wireless access interface;
- and
- operate in an inactive state by controlling the transmitter circuitry and the receiver circuitry to, via the wireless access interface:
- receive a first signal comprising a random access preamble and a first portion of data from the communications device;
- transmit a random access response message to the communications device;
- receive a second signal comprising a second portion of the data from the communications device;
- and
- transmit, based on whether the infrastructure equipment successfully receives the second portion, an acknowledgement or a negative acknowledgement (ACK/ACK) to the communications device.
Circuitry for a communications device, the circuitry comprising:
- transmitter circuitry;
- receiver circuitry;
- and
- control circuitry configured to control the transmitter circuitry and the receiver circuitry to:
- operate in an active state by controlling the transmitter circuitry and the receiver circuitry to transmit or receive signals representing data via a wireless access interface provided by one or more infrastructure equipment;
- and
- operate in an inactive state by controlling the transmitter circuitry and the receiver circuitry to, via the wireless access interface:
- transmit a first signal comprising a random access preamble and a first portion of data to an infrastructure equipment of the one or more infrastructure equipment;
- receive a random access response message from the infrastructure equipment;
- transmit a second signal comprising a second portion of the data to the infrastructure equipment;
- and
- receive, based on whether the infrastructure equipment successfully receives the second portion, an acknowledgement or a negative acknowledgement (ACK/NACK) from the infrastructure equipment.
