Adaptive CRC length for beam sweeping

Abstract

According to some embodiments, a method for use in a wireless transmitter of adaptive cyclic redundancy check (CRC) length selection comprises: obtaining a system parameter related to a number of beam sweeps used by the wireless transmitter for transmitting a wireless signal; selecting a CRC length based on the obtained system parameter; selecting a CRC polynomial of the selected length; generating CRC bits from time-dependent or time-independent information bits using the CRC polynomial; concatenating the generated CRC bits with the time-dependent or time-independent information bits; encoding the concatenated bits; and transmitting the encoded bits to a wireless receiver. The system parameter may comprise: a carrier frequency; a number of transmit antenna elements; a number of receive antenna elements; a transmitter antenna azimuth configuration; a transmitter antenna elevation configuration; an antenna polarization type; a beam scanning algorithm; and a cell type.
