Abstract: In aspects, a user equipment may be configured to determine a preconfigured frequency band that is less than an available system bandwidth. The UE may be further configured to perform an initial access procedure with a base station using the preconfigured frequency band. The initial access procedure may include a random access channel (RACH) procedure.

Abstract: In wireless communication systems that support 5G or 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 PDCCH) and a data channel (e.g., the 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.
