Abstract: Aspects described herein relate to processing synchronization signal block (SSB) signals and/or corresponding system information block (SIB) based on whether the SSB is received directly from a network node or from a router in a path from the network node. For example, a signal originated from a network node can be received. It can be determined whether the SSB is received from the network node or from a router in a path from the network node, and the SSB or a corresponding system information block (SIB) of the network node can be processed based on whether the SSB is received from the network node or the router. Other aspects relate to indicating whether a SSB is from a network node or a router in the path.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, the described techniques support resource offset mapping for multiplexing. Resource offset mapping may refer to the mapping of frequency-domain symbols to different subsets of resources that are offset from each other or separated by gaps. For instance, a first wireless device may map a first set of frequency-domain symbols to a first subset of subcarriers and a second set of frequency-domain symbols to a second subset of subcarriers. A lowest subcarrier of the second subset of subcarriers may be separated by an offset or a gap from a highest subcarrier of the first subset of subcarriers. As a result, at least some distortion experienced on subcarriers in the gap may not spread to other subcarriers, and the reliability and throughput of communications between the first wireless device and a second wireless device may improve.
