Method for Enhancing Measurement Capability of Terminal Device, Chip, and Terminal Device

A method, comprising:

• sending, by a terminal device, first information to a network device, wherein the first information indicates whether a measurement gap is required when the terminal device performs inter-frequency measurement;
• camping, by the terminal device, on a first cell and a second cell using a carrier aggregation (CA) technology, wherein the first cell and the second cell are long term evolution (LTE) cells, and the first cell is a primary cell;
• when the terminal device meets a preset first condition, or when the network device meets a preset second condition, sending, by the network device, a second message to the terminal device based on the first information, wherein the second message indicates to measure a network parameter of a third cell, and the second message comprises measurement gap information;
• reporting, by the terminal device, an event A2 of the second cell, wherein the event A2 enables the network device to de-configure the second cell;
• and
• sending, by the network device, a third message to the terminal device, wherein the third message indicates to measure the network parameter of the third cell, and the third message comprises no-gap information.
