Measurement method, base station and terminal

A measurement method, comprising:

• receiving, by a terminal, a switch message for a narrow bandwidth reception mode sent by a base station and switching to a designated narrow bandwidth to receive information, wherein a width of the narrow bandwidth is less than a width of a system bandwidth;
• and
• switching to the system bandwidth to measure a downlink reference signal transmitted by the base station over the system bandwidth according to scheduling of the base station when channel state information of a downlink channel of the system bandwidth needs to be measured;
• wherein switching to the system bandwidth to measure the downlink reference signal transmitted by the base station over the system bandwidth according to the scheduling of the base station when the channel state information of the downlink channel of the system bandwidth needs to be measured, comprises:
• receiving measurement parameters configured by the base station for the terminal to measure the downlink reference signal, wherein the measurement parameters comprise a cycle for the terminal to measure the downlink reference signal transmitted by the base station over the system bandwidth and information of a time period for the terminal to measure the downlink reference signal in the cycle;
• and
• switching to the system bandwidth to measure the downlink reference signal according to the measurement parameters.

A base station, comprising:

• a processor, a memory, a transceiver, and a bus, wherein the processor, the memory and the transceiver are connected through the bus, and the transceiver is used for receiving and transmitting signals and communicating with a terminal, and the memory is used for storing a group of program codes, and the processor is used for calling the program codes stored in the memory to perform the following operations:
• sending a switch message for a narrow bandwidth reception mode to a terminal through the transceiver to instruct the terminal to switch to a specified narrow bandwidth to receive information, wherein a width of the narrow bandwidth is less than a width of a system bandwidth;
• and
• scheduling the terminal to switch to the system bandwidth to measure a downlink reference signal transmitted by the base station over the system bandwidth when channel state information of a downlink channel of the system bandwidth needs to be measured;
• wherein the processor is specifically used for configuring measurement parameters for the terminal to measure the downlink reference signal and sending the measurement parameters to the terminal, wherein the measurement parameters comprise a cycle for the terminal to measure the downlink reference signal transmitted by the base station over the system bandwidth and information of a time period for the terminal to measure the downlink reference signal in the cycle;
