    摘要： 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.

    摘要： The application relates to the adaptation of the length of the cyclic redundancy check (CRC) code in the context of 3GPP NR. In 3GPP NR, the length of the uplink and downlink control information (UCI, DCI) significantly varies. Therefore, it is necessary to select a CRC code of appropriate size or length. Accordingly, a method (200) for use in a wireless transmitter comprises: determining an amount of data to transmit (212); determining a cyclic redundancy check (CRC) polynomial length based on the amount of data to transmit (214); encoding the data using a CRC of the determined polynomial length (216); and transmitting the encoded data (216). The data to transmit may not only comprise control channel data but also user data and may be encoded with a Polar code or a low-density parity check (LDPC) code.

    摘要： There is disclosed a method of operating a transmitting node in a millimeter-wave communication network. The method includes transmitting communication signaling in a transmission timing structure, the communication signaling including leading reference signaling in a leading time interval at the beginning of the transmission timing structure and including trailing reference signaling in a trailing time interval at the end of the timing structure. The leading reference signaling starts with a first reference signaling time-domain sequence, and the trailing reference signaling ending with the first reference time-domain signaling sequence. The disclosure also pertains to related devices and methods.
