Abstract
A transmission method of a base station is provided. The base station generates a first discovery signal block including a first PSS (primary synchronization signal) and a first SSS (secondary synchronization signal). The base station generates a second discovery signal block including a second PSS and a second SSS. Also, the base station transmits the first discovery signal block and the second discovery signal block.
Claims12
A method for transmitting discovery signals, performed by a base station operating a cell, the method comprising:
- generating M discovery signal blocks, each of the M discovery signal blocks including a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH), and a reference signal for demodulation of the PBCH, wherein M is a natural number equal to or greater than 1;
- determining a frequency resource for transmitting the M discovery signal blocks as one of candidate frequency resources in a frequency band to which the cell belongs;
- and
- transmitting the M discovery signal blocks through the determined frequency resource,
- wherein a frequency location of each of the candidate frequency resources is derived by each of frequency reference points, and a spacing of frequency reference points is defined as an integer multiple of a subcarrier spacing.
A method for receiving discovery signals, performed by a terminal, the method comprising:
- receiving a primary synchronization signal (PSS) among M PSSs constituting M discovery signal blocks through one of candidate frequency resources in a frequency band to which a cell belongs, each of the M discovery signal blocks including a PSS, a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH), and a reference signal for demodulation of the PBCH, wherein M is a natural number equal to or greater than 1;
- receiving a SSS, a PBCH, and a reference signal for demodulation of the PBCH through the one of the candidate frequency resources where the terminal received the PSS,
- wherein a frequency location of each of the candidate frequency resources is derived by each of frequency reference points, and a spacing of frequency reference points is defined as an integer multiple of a subcarrier spacing.
