As wireless communication technology advances, the bandwidth usage of wireless communications systems becomes increasingly flexible. For example, different user equipment (UEs) may support different bandwidths or radio frequency capabilities. However, a scheduling entity may not know wireless capabilities or characteristics (e.g., supported bandwidths, RF chain configurations, reconfiguration times, and/or the like) of the UEs for which the scheduling entity is to manage communications, which may hamper the ability of the scheduling entity to take advantage of the advances in flexible bandwidth usage described above. Techniques for synchronization, scheduling, bandwidth allocation, and reference signal transmission in a wireless communications system associated with flexible bandwidth allocation, such as a 5G network, are described herein.
