1. A method for wireless communication between a first device and a second device, the method comprising:
receiving, by the first device, a location information of the second device that includes a height information of the second device, the location information being represented as a location bit information or pilot sequences;
determining, by the first device, a location of the first device based on a reference signal receive power (RSRP) value of a reference signal from the second device, the determining includes whether the first device is located at an edge of a cell or a center of the cell;
determining, by the first device, a distance between the first device and the second device, wherein the distance is determined using a formula based on 1) a horizontal distance between the first device and the second device based on radius information of the cell and 2) a height information of the first device and the height information of the second device that is received from the second device; and
performing a transmission based on a timing adjustment that is determined using the distance, wherein the transmission comprises at least one of an identification information for the first device, uplink signaling information or beam information, and
wherein a modulation and coding scheme for the transmission is determined based on the distance determined by the first device, and
wherein at least one of a preamble set or a demodulation reference signal set is selected based on the modulation and coding scheme for the transmission,
wherein the performing of the transmission includes transmitting data that includes information of a spreading code for reconstructing of spread data symbol.
