Abstract: A channel characteristic obtaining method includes generating, by a first communication apparatus, a first reference signal and a first notification message, sending, by the first communication apparatus, the first reference signal and the first notification message to a second communication apparatus, and receiving, by the first communication apparatus, channel characteristic information of a first channel type from the second communication apparatus. The first channel type corresponds to first channel state information (CSI) determined by the second communication apparatus based on the first reference signal. The first notification message is useable to request the channel characteristic information of the first channel type. A channel characteristic of the first channel type is from a channel characteristic library. The channel characteristic library comprises channel characteristics of one or more channel types.

Abstract: Encoding of information bit sequences by use of an encoding device having more than two encoding entities is provided. Decoding of output codewords by a decoding device having more than two decoding entities is further provided. The encoding and the decoding are implemented through transmitting output codewords, generated by the encoding device, to the decoding device via a channel, wherein two or more user devices transmit the respective output codewords concurrently via the channel.

Abstract: This application provides an antenna detection method, an apparatus, a device, and a storage medium. The method includes: A first terminal device sends a first detection signal to a network device. The first detection signal is used to determine at least one first antenna sub-array corresponding to the first terminal device. A plurality of antenna sub-arrays of the network device include the at least one first antenna sub-array. A time interval at which the first detection signal is sent is related to spatial non-stationary coherence time. The first terminal device obtains first information from the network device. The first information indicates to perform information transmission through the at least one first antenna sub-array corresponding to the first terminal device.

Abstract: This application provides a communication method and apparatus, and relates to the field of communication technologies. In the method, a first communication apparatus determines a first index indicating a first precoding vector, and sends the first index to a second communication apparatus. The second communication apparatus receives the first index from the first communication apparatus, determines the first precoding vector based on the first index, and precodes data based on the first precoding vector. The first precoding vector includes spatial angle information and spatial depth information of a channel between the first communication apparatus and the second communication apparatus.

Abstract: A full duplex radio unit comprising a transmission unit, an antenna, a reception unit, a circulator and a power reduction unit is provided. The transmission unit is adapted to generate a first signal. The circulator is adapted to provide the first signal from the transmission unit to the antenna. The antenna is adapted to transmit the first signal and simultaneously receive a second signal using an identical frequency or frequency band. The circulator is adapted to provide a third signal to the power reduction unit, wherein the third signal comprises the second signal and interference generated from the first signal by the antenna and the circulator. The power reduction unit is adapted to reduce the power of the third signal by multiplying the third signal by factor of √ρ, wherein ρ is between zero and one, thereby generating a fourth signal.
