Abstract: Embodiment techniques map parity bits to sub-channels based on their row weights. The row weight for a sub-channel may be viewed as the number of “ones” in the corresponding row of the Kronecker matrix or as a power of 2 with the exponent (i.e. the hamming weight) being the number of “ones” in the binary representation of the sub-channel index (further described below). In one embodiment, candidate sub-channels that have certain row weight values are reserved for parity bit(s). Thereafter, K information bits may be mapped to the K most reliable remaining sub-channels, and a number of frozen bits (e.g. N−K) may be mapped to the least reliable remaining sub-channels. Parity bits may then mapped to the candidate sub-channels, and parity bit values are determined based on a function of the information bits.

Abstract: Embodiments of this application relate to the field of wireless communication technologies, and provide a signal processing method and an apparatus, to improve signal processing performance. In this method, a communication apparatus inputs N1 signal vectors to an input layer of a neural network for dimension increase processing, to obtain N2 high-dimensional signal vectors. The communication apparatus inputs the N2 high-dimensional signal vectors to an interaction layer of the neural network, to obtain a feature between the N2 high-dimensional signal vectors and a feature of each high-dimensional signal vector. The communication apparatus inputs the feature between the N2 high-dimensional signal vectors and the feature of each high-dimensional signal vector to an output layer of the neural network for an operation, to obtain an output signal vector.

Abstract: This application relates to a discontinuous reception method. In the first time unit, for example, the first symbol, after a hybrid automatic repeat request HARQ feedback occasion of a sidelink HARQ process, a first terminal may start a drx-HARQ-RTT-TimerSL and start a drx-RetransmissionTimerSL when the drx-HARQ-RTT-TimerSL expires. During running of the drx-RetransmissionTimerSL, the first terminal monitors a physical downlink control channel. In this way, sidelink retransmission efficiency can be improved, an increase of a sidelink retransmission delay can be avoided, and sidelink-based applications, such as unmanned driving, automatic driving, assisted driving, intelligent driving, networked driving, intelligent networked driving, and car sharing in the field of artificial intelligence can be better supported.
