Abstract: A multi-antenna operation mode indication method and an apparatus resolve a problem that increased power consumption and a resource waste are caused because a terminal device still operates in a multi-user multiple-input multiple-output (MU-MIMO) mode by default in a single-port transmission mode. The method includes: a network device sends indication information to a terminal device, to indicate that a multi-antenna operation mode of the terminal device is single-user multiple-input multiple-output (SU-MIMO) or MU-MIMO. The terminal device determines, based on the indication information from the network device, whether a demodulation reference signal (DMRS) port number corresponding to the terminal device and a DMRS port number not corresponding to the terminal device are allocated to another terminal device, to adjust the multi-antenna operation mode.

Abstract: A communication method and system, and a related apparatus. The communication method is applied to the communication system including a first device and a second device. In the communication method, the first device may indicate the second device to reserve a channel resource, and the second device does not perform data transmission on the reserved channel resource. This prevents the second device from occupying channel resources for long time, to release channel resources for a cellular communication system. The first device may schedule a terminal device other than the second device by using the released channel resources. This improves data transmission efficiency.

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.
