Optionally, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

It should be understood that the devices with communication functions in the network/system in the embodiments of the present application may be referred to as communication devices. Taking the communication system 100 shown in FIG. 1 as an example, the communication device may include a network device 110 and a terminal device 120 with a communication function, and the network device 110 and the terminal device 120 may be the specific devices described above, which will not be repeated here. The communication device may also include other devices in the communication system 100, such as network controllers, mobility management entities, and other network entities, which are not limited in the embodiments of the present application.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" in this article is just an association relationship that describes an associated object, indicating that there can be three relationships, for example, A and/or B, which can mean: A exists alone, A and B exist at the same time, exist alone B these three cases. In addition, the character "/" in this article generally indicates that the related objects before and after are in an "or" relationship.

The terminal device can continuously perform radio resource management (Radio Resource Management, RRM) measurement on the serving cell and other cells based on the network configuration under the Radio Resource Control (RRC) connection state to support mobility operations, such as handover Wait.

However, if the network performs RRM measurement configuration on the terminal device according to its own decision, without fully considering the status information of the terminal device, it may cause some terminal devices to continuously perform measurements, but these measurements may be unnecessary. For example, the terminal device is in a static state for a period of time. At this time, the positional relationship of the target cell to be measured, including the serving cell, relative to the terminal device does not change, so the continuous measurement results of the terminal device will not change, so these measurements are of little significance. Instead, it wastes power consumption of the terminal.

Therefore, the embodiments of the present application provide the following solutions, which can reduce the power consumption of the terminal device.

FIG. 2 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. The method 200 may include at least part of the following content.

In 210, the terminal device reports a first parameter to the network device, the first parameter characterizing a rate of change of the second parameter, and the second parameter is used to characterize the channel strength or channel quality measured by the terminal device.

FIG. 3 is a schematic flowchart of a wireless communication method 300 according to an embodiment of the present application. The method 300 includes at least part of the following content.

In 310, the network device receives a first parameter reported by the terminal device, where the first parameter characterizes a rate of change of the second parameter, and the second parameter is used to characterize the channel strength or channel quality measured by the terminal device.

Therefore, in the embodiment of the present application, the terminal device reports the first parameter representing the rate of change of the second parameter to the network device, so that the network device can decide whether to perform RRM measurement and/or RRM reporting configuration on the terminal device based on the first parameter Adjustment and determining the configuration suitable for the current RRM measurement and/or RRM reporting of the terminal device, so that the terminal device does not need to continuously perform RRM measurement or reporting, thereby reducing the power consumption of the terminal device.

In addition, the first parameter is the rate of change of the channel strength or channel quality measured by the terminal device. Since the rate of change of channel quality or strength is combined with cell coverage characteristics or cell radius, the configuration of RRM measurement or reporting can be better matched The current cell environment, so that the measurement or reporting configuration changes with the adaptability of the cell, can more accurately adjust the terminal device's RRM measurement or reporting behavior.

It is assumed that the terminal device reports to the network device the position movement rate based on the Global Positioning System (Global Positioning System, GPS). At this time, even at the same movement rate, the channel strength or quality changes under different coverage radii of the cell The rate will be different. In this case, if the same RRM measurement or RRM reporting configuration is performed, the RRM measurement or RRM reporting will not match the current cell coverage radius.

For example, in the case where the current serving cell is a small cell, if the terminal device reports the location movement rate based on GPS to the network device, even low-speed movement may cause a large change in channel quality or strength. The device configures a long RRM measurement or reporting period for the terminal device based on the low-speed movement of the terminal device, which will cause the terminal device to move out of the current serving cell and have not performed RRM measurement or reporting, thereby reducing the quality of the network device serving the terminal device .

For example, in the case where the cell radius of the current serving cell is large, if the terminal device reports the position movement rate obtained based on GPS to the network device, even high-speed movement will not cause a large change in channel quality or strength. If the network device configures a shorter RRM measurement or reporting period for the terminal device based on that the terminal device is moving at a high speed, this causes the terminal device to perform unnecessary RRM measurement or reporting, thereby increasing the power consumption of the terminal device.

In addition, since the coverage of the cell is usually circular or sector-shaped, the movement along the circumferential direction usually does not change the channel quality or channel strength, but the movement along the radial direction will cause the change in channel quality or channel strength, and the terminal equipment The position movement rate based on GPS is reported to the network device, and the movement direction of the terminal device is uncertain. The configuration of RRM measurement or reporting based only on the position movement rate obtained from GPS will result in useless RRM measurement or reporting. Or reduce the quality of service provided by network equipment to terminal equipment.

Therefore, in the embodiment of the present application, the first parameter characterizes the rate of change of the channel strength or channel quality measured by the terminal device. Since the rate of change of channel quality or strength has been combined with cell coverage characteristics or cell radius, RRM measurement or The reported configuration better matches the current cell environment, so that the measured or reported configuration changes as the cell adapts

It should be understood that the first parameter in the embodiment of the present application may be used for the configuration of RRM measurement or report of the measurement result, but it should be understood that the embodiment of the present application is not limited thereto, and the first parameter in the embodiment of the present application may also be used For other scenarios, for example, it is used in the channel state information (Channel State Information, CSI) or channel quality information (Channel Quality Information, CQI) measurement scenario, or it can also be used in the non-measurement scenario

It should also be understood that in the embodiment of the present application, the first parameter is the rate of change of the second parameter, but it should be understood that in the embodiment of the present application, the first parameter may be obtained based on the second parameter characterizing channel quality or strength, and At a non-change rate, the first parameter may further characterize the mobile state of the terminal device.

Optionally, in the embodiment of the present application, the first parameter may be a reference signal received power (Reference Signal Receiving Power, RSRP), a reference signal received quality (Reference Signal Receiving Quality, RSRQ), a reference signal-signal and interference plus Noise ratio (Reference Signal-Signal to Interference plus Noise Ratio, RS-SINR), CSI, CQI, these parameters can characterize the strength or quality of the channel.

For example, define the time rate of change of RSRP as: RSRP′=(RSRP2-RSRP1)/(t2-t1). Among them, RSRP1 is measured at time t1 and RSRP2 is measured at time t2.

Optionally, in the embodiment of the present application, the measurement object of the second parameter may include all or part of the currently served cell (for example, the primary cell or the secondary cell), the cell to be switched to, and the cell designated by the network side. Cells obtained based on certain criteria.

Optionally, in the embodiment of the present application, the measurement object of the second parameter includes at least one of the following: a primary serving cell; a secondary serving cell; at least one configured cell; and at least the highest signal strength of the measured cells One cell; at least one cell in the measured cell whose signal strength exceeds a threshold.

If the rate of change of the second parameter is slow, the configuration of RRM measurement and/or measurement result reporting may be more relaxed, for example, the period of measurement and/or reporting is longer, and/or the number of cells measured or reported may be Less, and/or fewer resources used for reporting, etc.
