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 45):
The method according to  claim 44 , wherein the performing, by the UE, the LBT on the first time-frequency resource of the unlicensed carrier further comprises at least one of:\n in the case that the first time-frequency resource is one OFDM symbol, performing, by the UE, a second LBT over a second time period within said one OFDM symbol; in the case that the first time-frequency resource is one OFDM symbol, performing, by the UE, a third LBT over a third time period within said one OFDM symbol; in the case that the first time-frequency resource is multiple OFDM symbols, performing, by the UE, the second LBT over a second time period within the second OFDM symbol of the multiple OFDM symbols or within the multiple OFDM symbols; in the case that the first time-frequency resource is multiple OFDM symbols, performing, by the UE, the third LBT over a third time period within the third OFDM symbol of the multiple OFDM symbols or within the multiple OFDM symbols; in the case that the first time-frequency resource is one sub-frame, performing, by the UE, the second LBT over a second time period within the second OFDM symbol of said one sub-frame or within said one sub-frame; in the case that the first time-frequency resource is one sub-frame, performing, by the UE, the third LBT over a third time period within the third OFDM symbol of said one sub-frame or within said one sub-frame;\n in the case that the first time-frequency resource is multiple sub-frames, performing, by the UE, the second LBT over a second time period within the second OFDM symbol of the multiple sub-frames or within the second sub-frame of the multiple sub-frames or within the multiple sub-frames; and \n in the case that the first time-frequency resource is multiple sub-frames, performing, by the UE, the third LBT over a third time period within the third OFDM symbol of the multiple sub-frames or within the third sub-frame of the multiple sub-frames or within the multiple sub-frames.
