1. A network device transmission bandwidth reduction method, comprising:
receiving, by a terminal, transmission bandwidth reduction configuration information sent by a network device, wherein the transmission bandwidth reduction configuration information comprises a set of transmission bandwidth reduction parameters supported by the network device; and
sending a target transmission bandwidth reduction coefficient to the network device, wherein the target transmission bandwidth reduction coefficient is a transmission bandwidth reduction coefficient that is of a serving cell and is expected by the terminal, and the serving cell comprises one or more cells that currently provide services for the terminal;
wherein the target transmission bandwidth reduction coefficient comprises at least one of the following:
transmission bandwidth reduction coefficients respectively corresponding to the serving cell, wherein the serving cell comprises cells that provide services for the terminal; or
a transmission bandwidth reduction coefficient jointly corresponding to the serving cell, wherein the serving cell comprises cells that provide services for the terminal; or
a transmission bandwidth reduction coefficient corresponding to a total bandwidth of the serving cell, wherein the serving cell comprises cells that provide services for the terminal.
