Description

Measurement method and communication device Technical Field The present application relates to the field of wireless communication, and more particularly, to a measurement method and a communication apparatus. Background In the current communication system, the network device periodically transmits some public signals (also called always transmitted public signals), so that the terminal can conveniently identify the network, and access the network. The network device frequently and periodically transmits the common signal, resulting in a high overhead for the network device. Based on this, release 19 (r 19) of the third generation partnership project (3rd generation partnership project,3GPP) began to study network energy conservation (network ENERGY SAVING, NES), which proposes introducing energy conservation by adaptive processing of common signals for some cells. Discussion of R19 NES includes enhancements in terms of on-demand SSB (on-demand SSB), on-demand SIB1 (on-demand SIB 1), common signal/channel adjustment (adaptation of common signal/channel transmissions). The OD-SSB is mainly aimed at a secondary cell (SCell) of a connected terminal device configured with carrier aggregation (carrier aggregation), and the SCell sends the SSB as required for the purpose of network energy saving. Disclosure of Invention The present application provides a measurement method and communication device designed to introduce an on-demand SSB in a measurement mechanism and to provide a measurement procedure related to the on-demand SSB, such as a procedure related to a serving cell measurement of the on-demand SSB. In a first aspect, a measurement method is provided. The method may be applied to the terminal side, that is, the method may be performed by the terminal device, or may be performed by a component of the terminal device (for example, a chip or a chip system or a circuit or a communication module), which is not limited in the present application. The following description will mainly take a terminal device as an example. The method may include receiving measurement configuration information for serving cell measurements based on-demand synchronization signal blocks on-demandSSB, measuring on-demandSSB of the serving cell based on the measurement configuration information, and transmitting measurement results. Based on the technical scheme, after introducing on-demandSSB, the network side can configure measurement configuration based on-demandSSB for the terminal equipment, so that the terminal equipment can conveniently measure the service cell based on-demandSSB. In addition, always-onSSB may have a longer period, the time required to complete the measurement and report is longer, and on-demandSSB may be sent densely. Thus, the measurement results of on-demandSSB can be understood as real-time measurement results, and can be immediately used for network measurement to perform some management based on the measurement results, such as carrier management. With reference to the first aspect, in some implementations of the first aspect, the measuring the on-demandSSB of the serving cell includes measuring the on-demandSSB of the serving cell if first indication information is received, where the first indication information indicates on-demandSSB to send. Based on the above technical solution, the terminal device may determine whether to measure the on-demandSSB of the serving cell when receiving the first indication information. The first indication information indicates on-demandSSB to send, so the terminal device can determine the time domain position of the on-demandSSB to send based on the first indication information, and accordingly make on-demandSSB measurement. Therefore, power consumption caused by blind searching of on-demandSSB by the terminal equipment when the on-demandSSB does not transmit can be avoided. With reference to the first aspect, in some implementations of the first aspect, the measuring the on-demand SSB of the serving cell in the case of receiving the first indication information includes measuring the on-demand SSB of the serving cell after a preset period of time after receiving the first indication information. With reference to the first aspect, in some implementations of the first aspect, the method further includes any one of measuring a always-transmitted synchronization signal block always-onSSB of the serving cell if the first indication information is not received, or measuring always-onSSB of the serving cell within a preset period after the first indication information is received, or measuring always-onSSB of the serving cell after a second indication information is received, where the second indication information indicates that on-demandSSB is not transmitted. Based on the above technical solution, the terminal device may perform the serving cell measurement based on always-onSSB without performing the serving cell measurement based on always-demandSSB, that is, without b
