Abstract: The present disclosure describes methods, systems and devices for wireless communication with limited channel bandwidth. One method includes determining, by a user equipment (UE), a transmission bandwidth, by receiving a synchronization signal or physical broadcast channel (SS/PBCH) block (SSB), wherein the transmission bandwidth is among a plurality of transmission bandwidths under a channel bandwidth, and the channel bandwidth is smaller than a bandwidth threshold.

Abstract: The present disclosure describes methods, systems and devices for transmitting information with limited channel bandwidth. The method includes transmitting, by a base station, a synchronization signal or physical broadcast channel (SS/PBCH) block (SSB) to a user equipment (UE), wherein a channel bandwidth is smaller than a bandwidth of the SSB, by at least one of: indicating, by the base station, an SSB index with at least one bit carried on a PBCH or a PBCH demodulation reference signal (DMRS) in the SSB; mapping, by the base station, at least one of PBCH DMRS or PBCH data on the channel bandwidth or the bandwidth of the SSB; and configuring, by the base station, a resource of a control resource set (CORESET) according to a frequency granularity.
