Title:
METHOD FOR TRANSMITTING PHYSICAL CHANNELS, USER EQUIPMENT THEREFOR, METHOD AND USER EQUIPMENT FOR RELAY TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2019/156505
Kind Code:
A1
Abstract:
The present invention discloses a physical channel transmission method, which includes: determining transmission subcarrier resources according to a configuration of a base station; and sending or receiving physical channels on the transmission subcarrier resources. Compared with the prior art, the present invention subdivides resource allocation units for transmitting physical channels from PRBs to subcarriers, which significantly improves the power spectral density of the uplink transmission and effectively achieves coverage enhancement.
