Abstract: This disclosure presents processes for improving the quality of NR PDCCH reception at a UE when transmitted in a same orthogonal frequency-division multiplexing (OFDM) symbol and a same frequency domain resource element as an LTE CRS. Using a capability parameter of the UE, a network node can transmit an LTE CRS and NR PDCCH in the same OFDM symbol and the same frequency domain resource elements using various encoding schemes. The encoding schemes can be one or more of puncture signalling, superposition signalling, relative power levels, UE type, adjusting the AL of the LTE CRS, or various combinations thereof. The UE can decode the PDDCH using the encoding scheme. Legacy UEs can be supported with this disclosure by the network node selecting supported UE capabilities for the encoding. The network node can balance transmission reliability with available resources.
