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 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: Embodiments of this application disclose a pilot signal sending and receiving method and apparatus, wherein the pilot signal sending method includes: establishing a first correspondence between a carrier identifier and a pilot pattern of a first type of pilot signal; establishing a second correspondence between a carrier identifier and a resource block set; acquiring a target carrier identifier of a target carrier; determining a location of a target resource block set corresponding to the target carrier identifier; determining a target pilot pattern that is of a first type of pilot signal and that corresponds to the target carrier identifier; mapping, according to the target pilot pattern, the first type of pilot signal to each resource block in the target resource block set on the target carrier. In this method, mapping is performed on a pilot signal only in a resource block set, which may reduce pilot redundancy and overheads.

Abstract: The present invention relates to the field of communications technologies, and discloses a method for accessing a base station by a terminal, and an apparatus. In this provided solution, after a control base station (CBS) receives an access request message sent by the terminal, the CBS determines, according to received identification information of the terminal and a correspondence between the data base station (DBS) identification (ID) and the identification information of the terminal, a DBS ID that accesses the terminal; then a DBS corresponding to the DBS ID allocates access resource information to the terminal; finally, the terminal accesses the DBS. Therefore, the terminal can also access the DBS even if there is no cell ID in a cell covered by the DBS, thereby avoiding a problem that the terminal cannot access the base station when accessing the base station in a data and signaling separation network.

Abstract: This application provides communication methods and communications apparatuses. In an example method, a first communications apparatus determines whether a first channel learning model is applicable, where the first channel learning model is used to determine first channel information based on target channel information, and a data amount of the first channel information is less than a data amount of the target channel information. The first communications apparatus sends a first message in response to determining that determining that the first channel learning model is not applicable, where the first message is used to indicate that the first channel learning model is not applicable. According to the example method, the first communications apparatus can determine applicability of the first channel learning model without assistance of a second communications 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.
