Abstract
Provided is a method for a base station executing a multi-beam-based random access procedure in wireless communication, and a device therefor. The method may include: transmitting information associated with a RACH resource to a terminal; receiving a multi-RACH preamble from the terminal by a multi-beam; and transmitting a random access response to the terminal.
Claims20
A communication method comprising;
- transmitting information related to one or more random access channel (RACH) resources to a user equipment through RRC signaling, the one or more RACH resources including information used for beam direction acquisition, different RACH resources mapped to each beam, and one or more RACH preambles being mapped on the one or more RACH resources based on Frequency Division Multiplexing (FDM);
- receiving one or more RACH preambles using the one or more RACH resources from the user equipment during a random access procedure;
- and
- transmitting a random access response to the user equipment,
- wherein the random access procedure is performed to select a suitable beam among multiple beams.

A communication method comprising;
- receiving configuration information related to one or more random access channel (RACH) resources from a base station through RRC signaling, the one or more RACH resources including information used for beam direction acquisition, different RACH resources mapped to each beam, and one or more RACH preambles being mapped on the one or more RACH resources based on Frequency Division Multiplexing (FDM);
- transmitting one or more allocated RACH preambles using the one or more RACH resources to the base station during a random access procedure;
- and

- cause to the user equipment to transmit one or more allocated RACH preambles using the one or more RACH resources to the base station during a random access procedure;
- and
- cause a user equipment to receive a random access response from the base station,
- wherein the random access procedure is performed to select a suitable beam among multiple beams.
