Abstract
A method includes acquiring system information or a physical broadcast channel PBCH that is broadcast by a base station, where the system information or the PBCH includes a preset physical random access channel PRACH, the preset PRACH includes m preset radio frames, and m is a positive integer; determining that a quantity of repetition times of a preamble sequence, which is used for random access, at a preset resource location of the preset PRACH is n, where 1≦n≦10m; and sending, at n preset resource locations of the preset PRACH, the preamble sequence to the base station.
Claims15
A preamble sequence transmission method, comprising:
- acquiring system information or a physical broadcast channel (PBCH) that is broadcast by a base station, wherein the system information or the PBCH comprises a preset physical random access channel (PRACH) that comprises m preset radio frames, m being a positive integer;
- determining that a number of repetition times of a preamble sequence, which is used for random access, at a preset resource location of the preset PRACH is n, wherein 1≦n≦10m;
- and
- sending the preamble sequence to the base station, the preamble sequence being sent at n preset resource locations of the preset PRACH.
A user equipment, comprising:
- a receiver, configured to receive system information or a physical broadcast channel (PBCH) that is broadcast by a base station, wherein the system information or the PBCH comprises a preset physical random access channel (PRACH) that comprises m preset radio frames, m being a positive integer;
- a processor, configured to determine that a number of repetition times of a preamble sequence, which is used for random access, at a preset resource location of the preset PRACH is n, wherein 1≦n≦10m;
- and
- a transmitter, configured to transmit, at n preset resource locations of the preset PRACH, the preamble sequence to the base station.
A base station, comprising:
- a transmitter, configured to broadcast system information or a physical broadcast channel (PBCH), wherein the system information or the PBCH comprises a preset physical random access channel (PRACH), the preset PRACH comprises m preset radio frames, and m is a positive integer;
- and
- a receiver, configured to receive, at n preset resource locations of the preset PRACH, k preamble sequences from user equipment, wherein the k preamble sequences are sent at the n preset resource locations of the preset PRACH after the user equipment determines that a quantity of repetition times of the preamble sequence, which is used for random access, at a preset resource location of the preset PRACH is n, wherein 1≦n≦10m, and k≦n.
