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 3):
The method according to  claim 1 , wherein the determining, by the terminal, a first signature according to a random number seed and a signature matrix comprises:\n generating, by the terminal, a random number according to the random number seed, randomly selecting a plurality of second signatures from the signature matrix according to the random number, and combining the plurality of second signatures into the first signature.
