Abstract

A wireless transmit/receive unit (WTRU) is configured to report to a network the WTRU capability for physical downlink control channel (PDCCH) decoding including supported number of discrete fourier transform (DFT) modules and sizes and receive from the network a PDCCH configuration as a search space and control resource set (CORESET) configurations having a spreading factor or an orthogonal code length, a number of frequency resource groups (FRGs) and associated sizes, an indication of code domain multiplexing, and a CORESET format. The WTRU determines resource groups (RG) size and a number of RGs per control channel elements (CCE) based on configured spreading factor and FRG size, and determines an association between RGs and orthogonal cover codes (OCCs) per FRG and orthogonal frequency division multiplexing (OFDM) symbol based on, among other things, the configured spreading factor.
