Abstract:
Methods, systems, and devices for wireless communications are described. A base station may transmit a synchronization signal block (SSB) burst set including a first set of SSBs transmitted using a first codebook and a second set of SSBs transmitted using a second codebook. In some cases, the first codebook may be configured for beamforming at a first transmission distance range (e.g., for far field transmissions) and the second codebook may be configured for beamforming at a second transmission distance range (e.g., for near field transmissions). Based on transmitting the SSB burst, the base station may receive an indication of a first SSB from the first set or the second set from a user equipment (UE). The base station may then communicate messages to the UE using a transmission beam and codebook associated with the first SSB indicated by the UE.
