5 . The method of claim 1 , comprising determining a beam sweep pattern,
wherein the discovery signal is transmitted by further considering the beam sweep pattern.
6 . The method of claim 5 , wherein the determining of the beam sweep pattern sweeps a first beam group first and, based on discovery failing, sweeps a second beam group.
7 . The method of claim 5 , wherein the determining of the beam sweep pattern adjusts a beam width of the first beam group.
8 . A terminal in a wireless communication system, comprising:
a transceiver; and
a processor coupled with the transceiver,

receive information on a location of the terminal,
generate a zone identify (zone ID) based on the information on the location of the terminal and determine discovery slot mapping in the one or more resource pools based on the zone identify, and
transmit a discovery signal based on the discovery slot mapping.
9 . The terminal of claim 8 , wherein the determining of the discovery slot mapping based on the zone identify generates a shift discovery value based on the zone identity and determines a discovery slot mapping set based on the shift discovery value.

12 . The terminal of claim 8 , wherein the processor is further configured to:
determine a beam sweep pattern, and
transmit the discovery signal by further considering the beam sweep pattern.
13 . The terminal of claim 12 , wherein the determining of the beam sweep pattern sweeps a first beam group first and, based on discovery failing, sweeps a second beam group.
14 . The terminal of claim 12 , wherein the determining of the beam sweep pattern adjusts a beam width of the first beam group.
15 . A terminal in a wireless communication system, comprising:
a transceiver; and
a processor coupled with the transceiver,
