Abstract: This application provides a communication method and apparatus, so that a first network device can configure a terminal device to send a demodulation reference signal symbol in a first different-configuration slot. A quantity of consecutive resource elements occupied by each demodulation reference signal code division multiplexing group included in a demodulation reference signal symbol is greater than 2. Therefore, a quantity of demodulation reference signal ports supported by each demodulation reference signal code division multiplexing group is greater than 2, so that an uplink communication capacity of the terminal in the different-configuration slot can be increased when a quantity of demodulation reference signal code division multiplexing groups in each demodulation reference signal symbol remains unchanged, to meet an uplink transmission requirement of the terminal device.

Abstract: This application relates to the field of short-range wireless communication technologies, and discloses a Bluetooth pairing method. The method includes: when a terminal receives a first operation of a user, the terminal sends an inquiry request to a Bluetooth device, where the inquiry request is used to obtain a Bluetooth address of the Bluetooth device. When receiving the inquiry request, the Bluetooth device sends an inquiry response to the terminal, where the inquiry response includes the Bluetooth address of the Bluetooth device. The Bluetooth device sends an extended inquiry response to the terminal, where the extended inquiry response includes a device name of the Bluetooth device. After receiving the extended inquiry response, the terminal displays the device name of the Bluetooth device. In this way, the terminal can reduce a time consumed by the terminal in a process from discovering the Bluetooth device to pairing with the Bluetooth device.

Abstract: A full-duplex communication apparatus and method are provided, and relate to the field of communication technologies, to improve a self-interference cancellation capability of the full-duplex communication apparatus. The full-duplex communication apparatus includes a first antenna, a second antenna, and a gating apparatus. The full-duplex communication apparatus may receive a first signal from the first antenna through the gating apparatus, and perform interference suppression or cancellation on the first signal; and may further transmit a signal through the second antenna.
