METHOD AND APPARATUS FOR COMMUNICATION OVER RADIO CHANNEL

摘要

FIELD: radio engineering, communication.SUBSTANCE: method comprises steps of: determining a first preamble format for use in a cell of a second communication device; determining a basic cyclic shift value from a set of basic cyclic shift values, wherein the set is selected based on the preamble format; and transmitting data containing an indication with respect to the determined first preamble format and an indicator of the basic cyclic shift value which indicates the basic cyclic shift value in the set of basic cyclic shift values.EFFECT: larger number of various preambles to be used in random access.21 cl, 10 dwg
