A radio communication method, comprising: receiving, by a network side device, a random access preamble signal transmitted by a user equipment, wherein duration of the random access preamble signal is one single carrier frequency division multiple access, SC-FDMA, symbol or one orthogonal frequency division multiplexing, OFDM, symbol; generating, by the network side device, a random access response and transmitting the random access response to the user equipment; wherein before receiving, by the network side device, the random access preamble signal transmitted by the user equipment, the method further comprising: determining, by the network side device, a sequence group number and a base sequence number of the random access preamble signal, wherein the determined sequence group number is consistent with a sequence group number of a sounding reference signal or a physical uplink shared channel demodulation reference signal, and the determined base sequence number is consistent with a base sequence number of the sounding reference signal or the physical uplink shared channel demodulation reference signal; transmitting, by the network side device, the determined sequence group number and the determined base sequence number to the user equipment; wherein before receiving, by the network side device, the random access preamble signal transmitted by the user equipment, the method further comprising: determining, by the network side device, a symbol used to carry a PRACH resource band or resource band pair of the random access preamble signal in an uplink subframe, wherein for a frequency division duplexing system, the symbol is the SC-FDMA symbol or OFDM symbol in the uplink subframe, or, for a time division duplexing system, the symbol is the last one or the last two SC-FDMA symbols or OFDM symbols in the uplink subframe or a special subframe. receiving, by a network side device, a random access preamble signal transmitted by a user equipment, wherein duration of the random access preamble signal is one single carrier frequency division multiple access, SC-FDMA, symbol or one orthogonal frequency division multiplexing, OFDM, symbol; generating, by the network side device, a random access response and transmitting the random access response to the user equipment; determining, by the network side device, a sequence group number and a base sequence number of the random access preamble signal, wherein the determined sequence group number is consistent with a sequence group number of a sounding reference signal or a physical uplink shared channel demodulation reference signal, and the determined base sequence number is consistent with a base sequence number of the sounding reference signal or the physical uplink shared channel demodulation reference signal; transmitting, by the network side device, the determined sequence group number and the determined base sequence number to the user equipment; determining, by the network side device, a symbol used to carry a PRACH resource band or resource band pair of the random access preamble signal in an uplink subframe, wherein for a frequency division duplexing system, the symbol is the SC-FDMA symbol or OFDM symbol in the uplink subframe, or, for a time division duplexing system, the symbol is the last one or the last two SC-FDMA symbols or OFDM symbols in the uplink subframe or a special subframe.
