Abstract: In wireless communication systems that support 5th generation wireless systems (5G) or New Radio (NR) protocols, subframes used for communication may have different numerology options. Numerology options may refer to the characteristics of the subframe such as a tone spacing within each symbol of the subframe, a symbol duration for each symbol of the subframe, a number of symbols in the subframe, etc. A subframe may include a control channel (e.g., the Physical Downlink Control Channel (PDCCH)) and a data channel (e.g., the Physical Downlink Shared Channel (PDSCH)). In an aspect, the control channel and the data channel within the subframe may have different numerologies. As such, a need exists to signal the numerology of the subframe to users and to determine whether and how to multiplex the control channel and the data channel into the subframe.
