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: This application relates to a communication method and apparatus. A terminal device sends first uplink data to a network device. After sending the first uplink data, the terminal device monitors a first downlink control channel in a first search space in a first duration; and after the first duration ends, the terminal device monitors a second downlink control channel in a second search space in a second duration. A length of a periodicity of the second search space is greater than a length of a periodicity of the first search space. In this case, the terminal device monitors the second downlink control channel based on the second search space at a low frequency. Therefore, the second search space with a long periodicity is set, so that power consumption of monitoring the downlink control channel by the terminal device can be reduced.
