US 11,770,281 B2 · Symbol processing method and apparatus

Abstract

This application provides a symbol processing method and related apparatus. The method includes: dividing a plurality of obtained complex-valued symbols into a plurality of sets, where each set corresponds to one transmit symbol, and the plurality of sets include a first set corresponding to a first transmit symbol; and mapping a first sequence and a second sequence to the first set, where an end position of the first sequence is a position of intercepting a cyclic prefix (CP) in the first transmit symbol, and an end position of the second sequence is an end position of the first transmit symbol. By mapping the sequences to the sets, an original cyclic prefix (CP) can be extended using a sequence with a flexible length, and flexible guard periods of different lengths can be configured for different users by adjusting the length of the sequences.

Dependent claims

A symbol processing method, comprising:

obtaining a plurality of complex-valued symbols;
dividing the plurality of complex-valued symbols into a plurality of sets, wherein each set corresponds to one transmit symbol, and the plurality of sets comprise a first set corresponding to a first transmit symbol;
mapping a first sequence and a second sequence to the first set, wherein an end position to which the first sequence is mapped is a position of intercepting a cyclic prefix (CP) in the first transmit symbol, and an end position to which the second sequence is mapped is an end position of the first transmit symbol;
and
performing frequency domain weighting and/or right cyclic shift on the first set to which the first sequence and the second sequence are mapped.

2 more elements

A symbol processing apparatus, comprising:

at least one processor;
and
one or more memories coupled to the at least one processor and the at least one processor invokes programming instructions stored in the one or more memories, and is configured to execute the programming instructions to cause the apparatus to:
obtain a plurality of complex-valued symbols;
divide the plurality of complex-valued symbols into a plurality of sets, wherein each set corresponds to one transmit symbol, and the plurality of sets comprise a first set corresponding to a first transmit symbol;
map a first sequence and a second sequence to the first set, wherein an end position to which the first sequence is mapped is a position of intercepting a cyclic prefix (CP) in the first transmit symbol, and an end position to which the second sequence is mapped is an end position of the first transmit symbol;
and
perform frequency domain weighting and/or right cyclic shift on the first set to which the first sequence and the second sequence are mapped.
