Multiplexing data over control resources in new radio

摘要

Enabling a wireless communication device to access services provided by a Radio Access Network, (e.g. a New Radio/5G network), in a communication between a first and a second wireless communications device (e.g. a gNB and a UE), wherein the communication includes at least one control region (e.g. PDCCH) including a group of physical resource blocks, the method comprising: multiplexing data within at least part of the control region to liberate space in the control region, such that the liberated space can be used for data transmission and improve spectral efficiency. The group of physical resource blocks, PRBs, comprises a COntrol REsource SET, CORESET (i.e. a group of PRBs for a certain number of Orthogonal Frequency Division Multiplexing (OFDM) symbols, to carry control information from the gNB to users). For CORESET level reuse, techniques are disclosed to use resources around unknown CORESETs and signalling to achieve this. In addition, a pattern-based technique with hierarchical refinement or its variation with additional bitmap indicating configured and unconfigured CORESETs is provided. For data multiplexing inside the CORESET at DCI/CCE level, the invention provides techniques to enable data multiplexing around other users’ CCEs which are normally unknown to a UE.
