Abstract: A (repeater) node may identify a first indication of a waveform switch associated with a first link between a base station and the node or a second link between the node and a UE. A waveform switch associated with the first link may be triggered by the base station or the node. A waveform switch associated with the second link may be triggered by the node or the UE. The waveform switch may correspond to a first switch from an OFDM waveform to an SC waveform or a second switch from the SC waveform to the OFDM waveform. The base station may transmit, to the node, an indication of a post-waveform switch resource mapping between a first waveform associated with the first link and a second waveform associated with the second link. The node may execute the waveform switch associated with the first link or the second link.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive, using a first beam, a first physical random access channel (PRACH) communication during a first random access channel (RACH) occasion. The base station may receive, during the first RACH occasion, a data communication having a timing that is aligned with a timing of the PRACH communication to provide a beam switching gap before reception of a second PRACH communication during a second RACH occasion. Numerous other aspects are described.
