    Abstract: Provided are a random access method and device, a user equipment and a storage medium. The method includes: determining listen-before-talk (LBT) priority levels for performing an LBT mechanism corresponding to messages transmitted during a random access process, and/or LBT priority levels of an LBT mechanism corresponding to different physical random access channel (PRACH) formats; and transmitting the messages for random access by means of the determined LBT priority levels corresponding to the messages and/or LBT priority levels corresponding to different PRACH formats after successfully performing the LBT mechanism. In such a way, the problem of the need of optimizing random access for a user equipment in the related art is resolved, thereby optimizing random access and improving the random access success rate.

    Abstract: A method and apparatus for sending and receiving uplink data, a terminal, and a base station are provided. The method comprises: determining, according to a self-defined instruction message or an instruction message received from a base station, a start symbol position or the start symbol position and an end symbol position for transmitting a subframe on a physical uplink shared channel (PUSCH) on an unlicensed carrier; and sending uplink data according to the start symbol position or according to the start symbol position and the end symbol position. By means of the embodiments of the present invention, the problem of failing to determine the time point of transmitting uplink data on an unlicensed carrier by a terminal is resolved, thereby achieving the effect of determining the time point of transmitting the uplink data on the unlicensed carrier by the terminal, and providing the effect of improving the data transmission efficiency.

    Abstract: Provided are an information processing method, apparatus and system. The method includes acquiring first information; and performing contention-based access and transmitting a sounding reference signal (SRS) according to the first information, where the first information includes at least one of the followings: a frame structure, a listen-before-talk (LBT) execution position, a SRS transmission position and dedicated indication signaling. The present disclosure solves a collision problem that occurs when a LBT detection position and a SRS transmission position are both on a last OFDM symbol of a subframe in the related art and achieves effects of improving a probability that a UE accesses a channel and increasing SRS transmission opportunities.
