  • Publication number: 20200067640
    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.

  • Publication number: 20190253188
    Abstract: Systems and methods are described herein that allow information carrying bits of a transmission block to be placed at higher-reliability positions prior to transmission. An exemplary method includes generating a set of payload bits to be encoded for transmission, wherein the set of payload bits includes at least one known bit, interleaving the set of payload bits to generate an interleaved set of payload bits, wherein the interleaved set includes the at least one known bit in a predetermined position in the interleaved set, providing the interleaved set to a cyclic redundancy check (CRC) encoder to generate CRC-interleaved set of payload bits, wherein the CRC-interleaved set includes the at least one known bit in a predetermined position within the CRC-interleaved set, and encoding the CRC-interleaved set for transmission to a wireless device. Associated network nodes and wireless devices are included.

  • Publication number: 20190229850
    Abstract: According to some embodiments, a method performed by a wireless device for polar encoding payload bits comprises: identifying payload bits of a data channel that have known values; placing a first subset of the known payload bits at input positions of a polar encoder that correspond to the earliest decoding bit positions of the polar encoder; placing a second subset of the known payload bits at input positions of the polar encoder that correspond to the least reliable decoding bit positions of the polar encoder after placement of the first subset of the known payload bits; and transmitting the polar encoded payload bits to a wireless receiver. The first subset of the known payload bits are placed in earliest decoding bit positions to improve early termination gain. The second subset of the known payload bits are placed in least reliable decoding bit positions to enhance error performance.
