Abstract
A method comprises communicating, between a terminal (102) and a base station (101), an uplink control message (6001, 6003) of a random access procedure, the uplink control message (6001, 6003) comprising an indicator indicative of uplink payload data (6005, 6007) queued for transmission during the random access procedure. The method also comprises configuring the random access procedure depending on the indicator and communicating, in the random access procedure configured in accordance with the indicator, the uplink payload data (6005, 6007).
Claims19
A method, comprising:
- communicating, between a terminal and a base station, an uplink control message of a random access procedure, the uplink control message comprising an indicator indicative of uplink payload data queued for transmission during the random access procedure,
- configuring the random access procedure depending on the indicator, and
- communicating, in the random access procedure configured in accordance with the indicator, the uplink payload data,
- wherein said configuring comprises:
- setting a count of repetitions of a Layer 3 connection request message of the random access procedure depending on the indicator.
A terminal device comprising control circuitry configured to perform:
- transmitting, to a base station of a wireless network, an uplink control message of a random access procedure, the uplink control message comprising an indicator indicative of uplink payload data queued for transmission during the random access procedure,
- configuring the random access procedure depending on the indicator, and
- transmitting, in the random access procedure configured in accordance with the indicator, the uplink payload data,
- wherein said configuring comprises:
- setting a count of repetitions of a Layer 3 connection request message of the random access procedure depending on the indicator.
A base station comprising control circuitry configured to perform:
- receiving, from a terminal device, an uplink control message of a random access procedure, the uplink control message comprising an indicator indicative of uplink payload data queued for transmission during the random access procedure,
- configuring the random access procedure depending on the indicator, and
- receiving, in the random access procedure configured in accordance with the indicator, the uplink payload data,
- wherein said configuring comprises:
- setting a count of repetitions of a Layer 3 connection request message of the random access procedure depending on the indicator.
