摘要： A random access method, user equipment (UE), a base station, and a random access system, are provided to address relatively long service delay. In various embodiments, after downlink synchronization with a cell is obtained, UE can determine a preamble sequence of the UE in the cell, where the UE has not obtained uplink synchronization with the cell. The UE can then obtain service data and generate a scrambling code, and scramble the service data based on the scrambling code to obtain scrambled service data. The UE can then configure, based on a predetermined resource mapping relationship, time-frequency resources respectively occupied by the preamble sequence and the scrambled service data. The UE then sends on the configured time-frequency resources, the preamble sequence and the scrambled service data to a base station the cell belongs to and receives random access response sent by the base station based on the preamble sequence.

摘要： A method for scheduling a terminal device comprises performing blind detection on N subframes by using at least one codebook and a pilot corresponding to the codebook, and determining, according to a blind detection result, a first pilot set corresponding to each codebook in each subframe, where correct terminal data cannot be obtained by performing blind detection by using a pilot in the first pilot set and a corresponding codebook. The method comprises determining, according to the first pilot set corresponding to each codebook, a second pilot set corresponding to each codebook, where a pilot in the second pilot set is a pilot that is in the first pilot set and that has already been sent by the terminal device, and determining a to-be-used transmission mode according to the second pilot set corresponding to each codebook in each subframe, where different transmission modes correspond to different spectrum multiplex rates.
