Abstract:
Provided are a preamble transmission method and apparatus. The method comprises: a UE executing LBT on a first time frequency resource of an unlicensed carrier until a right to use the unlicensed carrier is acquired, wherein the LBT comprises LBT executed for transmitting a preamble; and after a right to use the access to the unlicensed carrier is acquired, the UE transmitting the preamble on a second time frequency resource located behind the first time frequency resource, wherein the second time frequency resource is a pre-configured PRACH time frequency resource at a fixed position, or a PRACH time frequency resource determined according to an LBT execution position. By means of the present disclosure, the problem in the relevant art of intra-cell interference caused by uplink data transmission over an unlicensed carrier is solved, and the uplink data transmission quality is improved.

Claim (Index 47):
The method according to  claim 45 , wherein the first OFDM symbol is an OFDM symbol before the second OFDM symbol, and the second OFDM symbol is an OFDM symbol before the third OFDM symbol; or, the first time period is a time period before the second time period, and the second time period is a time period before the third time period; or, the first sub-frame is a sub-frame before the second sub-frame, and the second sub-frame is a sub-frame before the third sub-frame.
