Abstract: A signal transmission method and an apparatus are provided. The method includes: A sending device generates a sequence of a demodulation reference signal, and maps the sequence of the demodulation reference signal to a time-frequency resource of the demodulation reference signal for sending. The demodulation reference signal is used to estimate a channel state of a first channel, and the first channel carries uplink data. The time-frequency resource includes frequency-domain resources corresponding to a first CDM group, and the frequency-domain resources corresponding to the first CDM group are non-contiguous and equally spaced.

Abstract: This application provides a spatial reuse method and apparatus based on multi-access point (AP) coordination, and a system. In the method, a first access point AP sends a radio frame including identification information to a second access point AP. The identification information is used to indicate the second access point AP to perform spatial reuse during uplink data transmission performed by at least one first station associated with the first access point. The second access point sends a downlink frame to at least one second station based on the identification information. Through coordination between access points APs, the first AP may configure a spatial reuse transmission opportunity for another specific AP to perform spatial reuse transmission, so that a transmission time in the spatial reuse transmission opportunity is fully used, thereby avoiding a conflict and improving transmission efficiency.

Abstract: An encoding method and apparatus, a decoding method and apparatus, and a device are provided. The encoding method includes: obtaining K to-be-encoded bits (S301), where K is a positive integer; determining a first generator matrix, where the first generator matrix includes at least two sub-blocks distributed based on a preset position relationship, and the sub-block includes a plurality of first generator matrix cores (S302); generating a second generator matrix based on the first generator matrix, where the second generator matrix includes T sub-blocks, and a position relationship between two adjacent sub-blocks of the T sub-blocks is determined based on the preset position relationship (S303), where T is a positive integer; and polar encoding the K to-be-encoded bits based on the second generator matrix (S304), to obtain encoded bits. This can reduce encoding/decoding complexity.
