Method and apparatus for transmitting and receiving signal in communication system

摘要

A method of transmitting/receiving signals at a terminal in a communication system is provided. The method includes determining at least one first reception path with a lowest path loss from among first reception paths that receive a first reference signal from a base station, receiving a second reference signal through second paths set up based on the at least one first reception path, and transmitting an uplink access signal with a second uplink transmitting beam that corresponds to a second downlink receiving beam corresponding to a second path having a lowest path loss.

1. A method of transmitting an uplink (UL) access signal at a terminal in a communication system, the method comprising:
selecting a first downlink (DL) transmitting (TX) beam in a first set of DL TX beams based on measurements of a plurality of first reference signals for the first set transmitted by a Base Station (BS); selecting a second DL TX beam in a second set of DL TX beams based on measurements of a plurality of second reference signals for the second set transmitted by the BS, the second set being mapped to the first DL TX beam; and receiving, from the BS, signaling information including information about the second set of DL TX beams constituting each of DL TX beams included in the first set of DL TX beams; transmitting the UL access signal using resource allocation information for a second UL receiving (RX) beam corresponding to the second DL TX beam, obtained from the signaling information, wherein the selecting of the first DL TX beam comprises selecting a combination of the first DL TX beam and a first DL RX beam having a lowest path loss, among combinations of the first set and a third set of DL TX beams, using the first measurements.
