Telecommunications apparatus and methods

A method of operating a network access node in a wireless telecommunication system, the method comprising;

• determining a first preconfigured uplink resource configuration to use for receiving a plurality of preconfigured uplink resource transmissions from a terminal device;
• receiving data transmitted by the terminal device in accordance with the first preconfigured uplink resource configuration;
• determining the first preconfigured uplink resource configuration should be changed;
• determining a second preconfigured uplink resource configuration to use for receiving a plurality of preconfigured uplink resource transmissions from a terminal device;
• and
• receiving data transmitted by the terminal device in accordance with the second preconfigured uplink resource configuration.

A network access node for use in a wireless telecommunication system, wherein the network access node comprises controller circuitry and transceiver circuitry configured to operate together such that the network access node is operable to;

• determine a first preconfigured uplink resource configuration to use for receiving a plurality of preconfigured uplink resource transmissions from a terminal device;
• receive data transmitted by the terminal device in accordance with the first preconfigured uplink resource configuration;
• determine the first preconfigured uplink resource configuration should be changed;
• determine a second preconfigured uplink resource configuration to use for receiving a plurality of preconfigured uplink resource transmissions from a terminal device;
• and
• receive data transmitted by the terminal device in accordance with the second preconfigured uplink resource configuration.
