Abstract

A communication method and apparatus. A plurality of signals included in a first sequence to M subcarrier blocks used to transmit a reference signal are mapped, where an mth subcarrier block includes Qm subcarriers, and a plurality of signals mapped to a plurality of consecutive subcarriers at a rear location in the mth subcarrier block are the same as a plurality of signals mapped to a plurality of consecutive subcarriers at a front location in a (mod(m, M)+1)th subcarrier block. Signals transmitted on a plurality of reference signal subcarrier blocks are jointly designed, and a cyclic redundancy characteristic is formed in the plurality of reference signal (for example, PTRS) subcarrier blocks.

and
a processor connected to the memory, wherein the processor is configured to execute some or all of the computer programs or instructions in the memory to perform operations to:
map a first sequence to M subcarrier blocks used to transmit a reference signal, wherein an mth subcarrier block includes Qm subcarriers, Qm is an integer greater than or equal to 2, m is all of integers from 1 to M, M is an integer greater than or equal to 2, the first sequence includes a first plurality of signals, a second plurality of signals mapped to a second plurality of consecutive subcarriers at a rear location in the mth subcarrier block are same as the first plurality of signals mapped to a first plurality of consecutive subcarriers at a front location in a (mod(m, M)+1)th subcarrier block, and mod(m, M) is a remainder obtained by dividing m by M;
and
send the reference signal comprising at least one of the mapped first plurality of signals or the mapped second plurality of signals on each of corresponding M subcarrier blocks.

3 more elements
