Abstract:
The present invention discloses a terminal access method and an apparatus, to resolve a problem in an existing SCMA multi-terminal access mechanism that a conflict causes system performance degradation and may cause system retransmission. The method is as follows: determining, by a terminal, to enter a contention-based access phase; and determining, by the terminal during each transmission of binary data, a first signature according to a random number seed and a signature matrix, and mapping, according to the first signature, the binary data to a multi-dimensional symbol for transmission, where first signatures used during different transmissions of binary data are different.

Claim (Index 7):
The method according to  claim 6 , wherein the determining, by the base station according to a random number seed and a signature matrix of each terminal, a sequence of first signatures that is corresponding to each terminal comprises:\n generating, by the base station, random numbers according to the random number seed of a terminal for a plurality of consecutive times, sequentially selecting a first signature from the signature matrix according to each random number, and determining, according to the first signature corresponding to each random number, the sequence of first signatures that is corresponding to the terminal.
