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 15):
A base station, comprising:\n a receiving module, configured to receive, in a contention-based access phase, symbol sequences sent for a plurality of consecutive times by a terminal; a detection module, configured to sequentially detect a third signature comprised in each symbol sequence received by the receiving module, to obtain a sequence of third signatures; a determining module, configured to determine, according to a random number seed and a signature matrix of each terminal, a sequence of first signatures that is corresponding to each terminal; and a parsing module, configured to determine a sequence of first signatures, in the sequence of first signatures that is corresponding to each terminal and that is determined by the determining module, that is the same as the sequence of third signatures that is obtained by the detection module by means of detection; determine a terminal corresponding to the determined sequence of first signatures as a terminal sending the symbol sequences; and obtain corresponding binary data by parsing, according to the sequence of third signatures, each symbol sequence of the determined terminal.
