Method and apparatus for indicating deactivation of semi-persistent scheduling

A method for transmitting a signal for semi-persistent scheduling (SPS) deactivation in a wireless mobile communication system, the method comprising:

• filling, by a base station (BS), a first binary field related to resource allocation information contained in a downlink control channel signal entirely with ‘1’;
• filling, by the BS, a second binary field related to a transmission power control (TPC) and contained in the downlink control channel signal entirely with ‘0’;
• filling, by the BS, a third binary field related to a demodulation reference signal (DMRS) and contained in the downlink control channel signal entirely with ‘0’;
• and
• transmitting the downlink control channel signal to a user equipment (UE) for a deactivation of the SPS,
• wherein the deactivation of the SPS includes a release of a downlink assignment or an uplink grant.

A user equipment (UE) for a wireless mobile communication system, the UE comprising:

• a radio frequency (RF) unit;
• and
• a processor electrically connected to the RF unit,
• wherein the processor is configured to receive a downlink control channel signal related to a deactivation of a semi-persistent scheduling (SPS) through the RF unit, and to deactivate the SPS after the downlink control channel signal is received,
• wherein the deactivation of the SPS includes a release of a downlink assignment or an uplink grant,
• wherein the downlink control channel signal comprises:
• a first binary field related to resource allocation, the first binary field being entirely filled with ‘1’,
• a second binary field related to a transmission power control (TPC), the second binary field being entirely filled with ‘0’, and
• a third binary field related to demodulation reference signal (DM RS), the third binary field being entirely filled with ‘0’.
