Communication method, terminal device, and network device

A method of communication, comprising:

• determining, by a network device based on a first antenna panel to which a first receive parameter belongs and a second antenna panel to which a second receive parameter belongs, a beam switching time required by a terminal device to switch from the first receive parameter to the second receive parameter, wherein the first receive parameter is used by the terminal device to receive control information, and the second receive parameter is used by the terminal device to receive a to-be-transmitted signal;
• determining, by the network device, a position of the to-be-transmitted signal in time domain based on the beam switching time;
• sending, by the network device, the control information to the terminal device, wherein the control information is used to indicate the second receive parameter and the position of the to-be-transmitted signal in time domain;
• and
• sending, by the network device, the to-be-transmitted signal to the terminal device based on the position of the to-be-transmitted signal in time domain.

A communications apparatus, comprising:

• a receiver configured to use a first receive parameter to receive control information sent by a network device, wherein the control information is used to indicate a second receive parameter used by the communications apparatus to receive a to-be-transmitted signal;
• and
• a processor configured to determine, based on a first antenna panel to which the first receive parameter belongs and a second antenna panel to which the second receive parameter belongs, a beam switching time required for switching from the first receive parameter to the second receive parameter,
• wherein the receiver is further configured to receive the to-be-transmitted signal based on the beam switching time.
