Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may determine a mobility state. The network node may determine a communication configuration, selected from a plurality of communication configurations associated with a plurality of mobility states, based at least in part on the mobility state. The network node may perform a communication procedure using the selected communication configuration. Numerous other aspects are provided.
