摘要： The present invention provides a method of selecting a random access preamble in a radio communication system operable at least on a physical layer and a medium access control layer. Random access preambles are divided into at least two groups, the groups depending on at least one of the following: radio conditions and a size of a message to be transmitted by user equipment. The method comprising: (a) the medium access control layer selecting one of the preamble groups; (b) the medium access control layer randomly selecting one random access preamble within the selected group; (c) the medium access control layer signalling the selected random access preamble to the physical layer; and (d) the physical layer generating and transmitting the generated random access preamble.

摘要： A method for transmitting a random access preamble to a base station includes generating the random access preamble from a Zadoff-Chu (ZC) sequence having a length N, wherein the random access preamble is generated by considering a cyclic shift of the ZC sequence; and transmitting the random access preamble to the base station, wherein the cyclic shift is given by using a variable M corresponding to a Doppler shift of one subcarrier spacing, and wherein parameters associated with defining the cyclic shift are differently defined based on whether the variable M is less than ⅓ of the length N.

摘要： A method for generating an uplink transmission burst includes using one or more symbols to define the uplink transmission burst, and forming a preamble portion and a payload portion for the uplink transmission burst. The preamble portion is formed using at least a portion of one or more of the symbols, such that the preamble portion includes a signature that is defined in a predetermined signature set. The payload portion is formed using at least a portion of one or more of the symbols. Typically, at least a portion of the preamble portion and at least a portion of the payload portion are formed using the same symbol.
