摘要
Systems and methods for multi-stage downlink control information transmission in a manner that supports existing polar codes are provided. In some embodiments, a method of operation of a radio access node in a cellular communications network to transmit multi-stage downlink control information comprises transmitting a first part of a multi-stage downlink control information in a first Orthogonal Frequency Division Multiplexing (OFDM) symbol and transmitting a second part of the multi-stage downlink control information in a second OFDM symbol that is subsequent to the first OFDM symbol. Cyclic Redundancy Check (CRC) bits are attached to the first part of the multi-stage downlink control information and/or CRC bits are attached to the second part of the multi-stage downlink control information. In some embodiments, the first part and/or the second part of the multi-stage downlink control information is encoded using a polar encoder.
