Abstract: A method and apparatus for communication in millimeter wave multiple input multiple output (MIMO) communication are provided. A beamforming matrix by groups for terminals that are classified into a group is generated, and a pilot signal that is beam-formed based on the generated beamforming matrix by groups is transmitted to the terminals. Channel information based on the pilot signal is received from the terminals, hybrid beamforming scheduling is performed based on the channel information, and data is transmitted to the terminals based on the scheduling.

Abstract: Provided is a method for feeding back a channel quality indicator (CQI) by a terminal. The terminal receives, from a base station, at least one reference signal through at least one of multiple beams of the base station. The terminal measures a signal-to-interference plus noise ratio (SINR) for the at least one reference signal. The terminal determines a first level corresponding to the measured SINR among levels of a first CQI. In addition, the terminal feeds back the first CQI having the first level to the base station.

Abstract: A method in which a base station transmits pilot signals in a multiple-antenna communication system is provided. The base station includes some of the plurality of pilot signals distinguished by at least one of time domain symbols, subcarriers, and orthogonal codes in a first set to which a first random number is applied. The base station includes the remaining pilot signals, excluding the pilot signals that are included in the first set, in a second set that uses the same resources as used by the first set and to which a second random number different from the first random number is applied. The base station transmits at least one of the pilot signals that belong to the first set and the second set.

Abstract: In a communications system using a plurality of beams, a terminal determines a beam to be communicated with the terminal among the plurality of beams, determines one sequence among sequences allocated to the determined beam as a beam based random access preamble, and transmits the beam based random access preamble through the determined beam. In addition, if a random access response for the beam based random access preamble is not received from a base station for a set interval, the terminal determines one sequence among sequences in a cell based random access preamble collection as a cell based random access preamble and transmits the cell based random access preamble.

Abstract: A method of a reflecting node may comprise: receiving, from a first node, power control information that sets an amplification amount of a first signal transmitted from the first node to a second node in an n-th slot, n being a natural number; amplifying the first signal received from the first node based on the power control information; and reflecting the amplified first signal to the second node, wherein the power control information includes information on a mode of a reflector included in the reflecting node, a maximum transmission power of the reflecting node, a signal power expected to be received at reflecting elements of the reflecting node, a first transmission gain function, and a first parameter set.

Abstract: A base station using a plurality of beams transmits a plurality of training beams, receives measurement information regarding a first number of training beams with a highest received signal strength indication (RSSI) from each of a plurality of terminals which have received the plurality of training beams, generates an RSSI table representing RSSIs of terminals and beam indices on the basis of the measurement information regarding the first number of training beams of each terminal, and subsequently schedules terminals to perform simultaneous transmission among the plurality of terminals using the RSSI table.
