A non-transitory, computer-readable storage medium for use with a user equipment in a mobile communication system, the non-transitory, computer-readable storage medium storing instructions, that when executed by a processor, cause the processor to control the user equipment to perform operations comprising:
- receiving control channel signaling including a new data indicator and a modulation and coding scheme field;
- determining that the new data indicator and the modulation and coding scheme field of the control channel signaling indicates a predetermined combination of a new data indicator value and a modulation and coding scheme index;
- and
- deactivating a semi-persistent resource allocation in response to the determining that the new data indicator and the modulation and coding scheme field of the control channel signaling indicates a predetermined combination of a new data indicator value and a modulation and coding scheme index.
