Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Provided is a method of transmitting signals in an FBMC/OQAM system. Data symbols transmitted in category-2 data symbols or category-3 data symbols are determined according to interference from all of adjacent OQAM data symbols and an intrinsic interference coefficient of category-2 data symbols interference experienced by category-3 data symbols in a user data block, so that transmission symbols in the category-3 data symbols composed of transmitted data symbols and interference include target data symbols of the category-3 data symbols and target data symbols of the category-2 data symbols. A transmitting device transmits the data symbols of the category-3 data symbols and data symbols transmitted in category-2 data symbols together with other data symbols in the user data block.

Each group of the one or more groups of resource indicators respectively corresponds to at least one frequency subband from the set of frequency subbands. A resource indicator from the one or more groups of resource indicators is a synchronization signal block resource indicator (SSBRI) or a CSI reference signal resource indicator (CRI).
