摘要： The present invention relates to the field of wireless communications. Disclosed are a method and apparatus for sending a sounding reference signal. The method comprises: contending for a use permission of an unlicensed carrier according to listen-before-talk (LBT) or clear channel assessment (CCA) detection; and when the use permission of the unlicensed carrier is successfully contended, sending a sounding reference signal (SRS) on the unlicensed carrier. A method for transmitting an SRS and a PUSCH simultaneously or not simultaneously and a method for sending SRSs at part of uplink subframes are provided, and more SRS sending opportunities are provided. In downlink transmission, an SRS sequence is used as an occupied signal, thereby simplifying design of the occupied signal.

摘要： 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.
