1. A method by a terminal, the method comprising:
receiving, by the terminal from a base station, a RRCReconfiguration, wherein the RRCReconfiguration includes a one or more gap configuration information, wherein each of the one or more gap configuration information includes a gap identifier Information Element (IE) and a gap offset IE and a gap length IE and a gap repetition period IE;
configuring, by the terminal, a one or more preconfigured gaps based on the one or more gap configuration information;
deactivating, by the terminal, the one or more preconfigured gaps;
triggering, by the terminal, a gap request message in case that:
location measurement towards new radio is started; and
at least one of the one or more preconfigured gaps meets requirement;
triggering, by the terminal, a Scheduling Request (SR) for the gap request message in case that:
a Uplink Shared Channel (UL-SCH) resource is available; and
the UL-SCH resource does not accommodate the gap request message and a Medium Access Control (MAC) subheader;
transmitting, by the terminal to the base station, a first MAC Protocol Data Unit (PDU), wherein the first MAC PDU includes the gap request message;
receiving, by the terminal from the base station, a second MAC PDU, wherein the second MAC PDU includes a gap response message; and
activating, by the terminal, a preconfigured gap of the one or more preconfigured gaps based on a second information in the gap response message,
wherein:
the gap request message includes a first information;
the first information is to request activation of a preconfigured gap of the one or more preconfigured gaps; and
the first information includes a gap identifier of the preconfigured gap, and
wherein
the gap response message includes the second information;
the second information indicates activation of the preconfigured gap of the one or more preconfigured gaps; and
the second information includes the gap identifier of the preconfigured gap and a field indicating activation or deactivation of the preconfigured gap.
