    摘要： Systems, methods, and devices for beamforming (BF) training are disclosed. In some examples, a receiver is configured to receive sector sweep (SSW) training frames from an initiator device that each indicate an antenna sector of the initiator device. A transmitter is configured to transmit sector sweep (SSW) training frames to the initiator device that indicate a best received antenna sector of the initiator device. The receiver receives a sector sweep feedback (SSW FB) frame from the initiator device, and the transmitter transmits transmit a sector sweep acknowledgement (SSW ACK) frame to the initiator device that indicates an antenna sector of the initiator device that is different from the antenna sector indicated by the SSW FB frame, if the SSW FB frame was best received by an antenna not corresponding to the best received antenna sector of the initiator device.

    摘要： In a first example embodiment, a control transmission portion of a mmWave communication is received at a user equipment. The control transmission portion is divided into a plurality of control transmission portion sub-regions, each sub-region scheduling a data transmission for a corresponding sub-region of a data transmission portion of the mmWave communication. Then a first of the control transmission portion sub-regions is demodulated and decoded. A receive analog antenna beamforming is armed according to the demodulated and decoded first of the control transmission portion sub-regions. Beamforming is performed on a first sub-region of the data transmission portion of the mmWave communication, the first sub-region of the data transmission portion corresponding to the first of the control transmission portion sub-regions. During the arming and performing, a second of the control transmission portion sub-regions is demodulated and decoded.

    摘要： The present disclosure provides a terminal and a base station in a communication system. The terminal includes: a receiving unit configured to receive, from a base station, first information indicating a first parameter, where the first parameter indicates a number of candidate transform domain vectors regarding a subcarrier-level precoding matrix, and a value of the first parameter is smaller than a number of subcarriers of the communication system; the receiving unit being further configured to receive, from the base station, second information indicating a second parameter, where the second parameter indicates a number of transform domain vectors used to determine the subcarrier-level precoding matrix; and a control unit configured to determine, from the number of candidate transform domain vectors indicated by the first information, the number of transform domain vectors indicated by the second information.

    摘要： Disclosed is a method for sending a control channel. The method includes: a first communication node determining second transmission parameter information about the control channel according to at least one of first control information or first parameter information and sending the control channel to a second communication node according to the second transmission parameter information. The first parameter information includes at least one of the following information: information about a demodulation reference signal corresponding to the first control information, information about a demodulation reference signal of a data channel corresponding to the control channel, information about a type of second control information transmitted on the control channel, and information about a channel coding rate corresponding to the first control information. The first control information is sent by the second communication node to the first communication node and the second control information is sent by the first communication node to the first communication node. The second control information is on the control channel. Further disclosed are a device for sending a control channel, a method for receiving a control channel and a device for receiving a control channel.
