Wireless communication using different types of cyclic prefixes
The disclosure relates in some aspects to communicating different symbols with different types of cyclic prefixes. For example, a first symbol may have a first type of orthogonal frequency-division multiplexing (OFDM) cyclic prefix while a second symbol (e.g., immediately following the first symbol) may have a second type of OFDM cyclic prefix. In scenarios where a cyclic prefix does not include any chips (samples), the beamforming configuration for a transmitter can be changed during the cyclic prefix. At the receiver, the cyclic prefix is reconstructed based on the chips (samples) received during the symbol.
