Method and apparatus for transmitting scheduling request for gap activation transmission in wireless communication system

A terminal in a wireless communication system, the terminal comprising:

• a transceiver configured to transmit and receive signals;
• and
• a controller configured to control the transceiver to:
• transmit to a base station a UECapabilityInformation, the UECapability Information includes a first capability information related to positioning gap activation and a second capability information related to positioning gap activation, the first capability information indicates support for positioning gap activation with uplink Medium Access Control (MAC) Control Element (CE), and the second capability information indicates support for positioning gap activation with downlink MAC CE;
• receive from the base station a RRCReconfiguration, the RRCReconfiguration includes one or more gap configurations, a MAC-CellGroupConfig, and one or more uplink bandwidth part configurations, each of the one or more gap configurations includes an identifier of a gap, the MAC-CellGroupConfig includes a first field and one or more first configurations, each of the one or more first configurations includes an identifier1, a value for a prohibit timer, and a value for a counter, each of the one or more uplink bandwidth part configurations includes one or more second configurations, and each of the one or more second configurations includes the identifier1, an identifier2, and a parameter indicating periodicity and offset;
• trigger a Scheduling Request for a first MAC CE if the first MAC CE has been triggered and not cancelled and if uplink shared channel resources are not available for a new transmission;
• perform Scheduling Request transmission based on a specific first configuration and a specific second configuration;
• transmit, to the base station, the first MAC CE to request activation of a first gap;
• and
• receive, from the base station, a second MAC CE, the second MAC CE includes a fourth field and a fifth field, the fourth field indicates activation or deactivation of a second gap, and the fifth field includes a value corresponding to an identifier of the second gap,
• wherein the specific first configuration is the first configuration indicated by the first field, and the specific second configuration is the second configuration associated with the first configuration indicated by the first field, and
• wherein the first MAC CE includes a second field and a third field, the second field includes a value corresponding to the identifier of the gap, and the third field indicates activation or deactivation of the first gap.

A method performed by a base station, the method comprising:

• receiving, by the base station from a terminal, a UECapabilityInformation, the UECapabilityInformation includes a first capability information related to positioning gap activation and a second capability information related to positioning gap activation, the first capability information indicates support for positioning gap activation with uplink Medium Access Control (MAC) Control Element (CE), and the second capability information indicates support for positioning gap activation with downlink MAC CE;
• transmitting, by the base station to the terminal, a RRCReconfiguration, the RRCReconfiguration includes one or more gap configurations, a MAC-CellGroupConfig, and one or more uplink bandwidth part configurations, each of the one or more gap configurations includes an identifier of a gap, the MAC-CellGroupConfig includes a first field and one or more first configurations, each of the one or more first configurations includes an identifier1, a value for a prohibit timer, and a value for a counter, each of the one or more uplink bandwidth part configurations includes one or more second configurations, and each of the one or more second configurations includes the identifier1, an identifier2, and a parameter indicating periodicity and offset;
• performing, by the base station, Scheduling Request reception based on a specific first configuration and a specific second configuration;
• receiving, by the base station from the terminal, the first MAC CE related to activation of the first gap;
• and
• transmitting, by the base station to the terminal, a second MAC CE, the second MAC CE includes a fourth field and a fifth field, the fourth field indicates activation or deactivation of a second gap, and the fifth field includes a value corresponding to an identifier of the second gap,
• wherein the specific first configuration is the first configuration indicated by the first field, and the specific second configuration is the second configuration associated with the first configuration indicated by the first field, and
• wherein the first MAC CE includes a second field and a third field, the second field includes a value corresponding to the identifier of the gap, and the third field indicates activation or deactivation of the first gap.
