Network device transmission bandwidth reduction method and device

A network device transmission bandwidth reduction method, comprising:

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

A terminal, comprising a processor and a memory, wherein;

• the memory is configured to store a program instruction;
• and
• the processor is configured to invoke the program instruction in the memory to perform:
• receiving 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 that 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 one or more cells that provide services for the terminal;
• or
• a transmission bandwidth reduction coefficient jointly corresponding to the serving cell, wherein the serving cell comprises one or more 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 one or more cells that provide services for the terminal.
