Title:
ADAPTATION OF CRC CODE LENGTH FOR 3GPP NR
Document Type and Number:
Japanese Patent JP2023109809
Kind Code:
A
Abstract:
To provide a method and a wireless transmitter for adapting the length of the cyclic redundancy check (CRC) code in the context of 3GPP NR in which the length of uplink and downlink control information (UCI, DCI) significantly varies.SOLUTION: A method for use in a wireless transmitter comprises: determining an amount of data to transmit; determining a cyclic redundancy check (CRC) polynomial length based on the amount of data to transmit; encoding the data using a CRC of the determined polynomial length; and transmitting the encoded data. 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.SELECTED DRAWING: Figure 2A
