Abstract
A wireless communication system utilizes a synchronization signal block (SSB) structure to enable beam switching at higher sub carrier spacing (SCS) or uplink transmissions within an SSB. The SSB structure has a first SCS for an SSB transmission and a second SCS for a data transmission. The SSB structure is based on the first SCS and the second SCS, with the SSB structure including at least one gap between SSB symbols or between SSBs. The wireless communication system transmits or receives an SSB based on the SSB structure. A base station may transmit a downlink signal during the gap, for example, where the second SCS is much greater than the first SCS. A user equipment may transmit an uplink signal such as an acknowledgment during the at least one gap. The user equipment or the base station may perform analog beam switching during the at least one gap between SSBs.
