Claim of US Patent No. 11,032,802

1. A method of operating a terminal device that communicates in a wireless telecommunications system, the method comprising:determining, in a case that uplink data is waiting for transmission to the wireless telecommunications system, to transmit a resource allocation request to the wireless telecommunications system, the resource allocation request being for a desired allocation of radio resources to the terminal device for transmission of the uplink data;
waiting, in the case that the uplink data is waiting for transmission to the wireless telecommunications system, to receive a radio resource allocation message from the wireless telecommunications system, the radio resource allocation message indicating allocated radio resources to be used for transmissions associated with the uplink data;
receiving the radio resource allocation message transmitted from the wireless telecommunications system, wherein the wireless telecommunications system having allocated, in response to the wireless telecommunications system receiving the resource allocation request from one of the terminal device and another terminal device, (i) the allocated radio resources to the terminal device by sending the radio resource allocation message to the terminal device for the transmissions associated with the uplink data and (ii) other allocated radio resources to the another terminal device by sending another radio resource allocation message to the another terminal device;
second determining that the allocated radio resources are not sufficient for the uplink data waiting for transmission to the wireless telecommunications system; and
transmitting, after receiving the radio resource allocation message, an indication and the uplink data using the allocated radio resources derived from information in the radio resource allocation message, wherein
the indication indicates a difference between the allocated resources used in the transmitting and the desired allocation of radio resources indicated in the request.
