Abstract
The present disclosure provides a radio communication method, a user equipment, and a network side device, the radio communication method includes: receiving, by a network side device, a random access preamble signal transmitted by a user equipment, where duration of the random access preamble signal is one SC-FDMA symbol or one OFDM symbol, thus air interface overhead of random access can be greatly reduced in a condition that a user equipment can access a cell randomly. The cell may be a microcell or other similar cells.
Claims20
A radio communication method, comprising:
- receiving, by a network side device, a random access preamble signal transmitted by a user equipment, wherein a 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 according to the random access preamble signal;
- and
- transmitting the random access response to the user equipment.
A network side device, comprising:
- a receiving module, configured to receive a random access preamble signal transmitted by a user equipment, wherein a 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;
- a processing module, configured to generate a random access response according to the random access preamble signal received by the receiving module;
- and
- a transmitting module, configured to transmit the random access response generated by the processing module to the user equipment.
A user equipment, comprising:
- a generating module, configured to generate a random access preamble signal, wherein a 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;
- a transmitting module, configured to transmit the random access preamble signal generated by the generating module to a network side device;
- and
- a receiving module, configured to, after the transmitting module transmits the random access preamble signal, receive a random access response transmitted by the network side device.
