Abstract: A sending device may determine a mother code in a kth transmission based on a length of to-be-transmitted bits in the kth transmission. k is an integer greater than or equal to 2. The sending device may perform systematic polar encoding on to-be-coded bits in the kth transmission based on the mother code, to obtain the to-be-transmitted bits. The sending device may send the to-be-transmitted bits.

Abstract: Embodiments of this application provide a radio channel data processing method, a communication apparatus, and a related device. In the method, a first communication device may send an uplink resource request message to a second communication device. The uplink resource request message includes source distribution information and a first modulation and coding scheme determined based on the source distribution information. The first communication device receives an uplink resource allocation message from the second communication device. The uplink resource allocation message includes a modulation and coding scheme allocated by the second communication device to the first communication device. The first communication device performs modulation and coding on an information bit based on the second modulation and coding scheme. This helps improve coding performance of the first communication device.

Abstract: It is possible to reduce the PAPR of an amplified signal communicated over bonded channels by applying different phase shifts to control fields communicated over the bonded channels. The phase shifts reduce the amount of constructive interaction between the control fields by shifting the peaks of the respective signals in the time domain. The control fields may include short training fields (STFs), channel estimation (CE) fields, or header fields communicated over bonded channels.
