A measurement method, base station and terminal of a wireless communication network

Abstract

Embodiments of the present invention provide a measurement method for a wireless communication network, a base station, and a terminal, which relate to the communication field. The method includes: sending measurement configuration information to the terminal; wherein, the measurement configuration information includes: carrying types used to distinguish measurement objects The measurement object configuration information indicated by the distinction; receiving the measurement result sent by the terminal after measuring the determined measurement object, the determined measurement object is determined by the terminal according to the distinction indication; the type of the measurement object includes: LAA frequency The LAA cell at the LTE frequency point, the LTE cell at the LTE frequency point, or the MF cell at the MF frequency point; the indication of the distinction is an absolute radio frequency channel number. The solution of the present invention enables the terminal to distinguish the type of measurement object, such as LAA and MF measurement objects, and enables the terminal to measure the channel quality of the frequency points of the entire or part of the MF frequency band, thereby supporting the handover of the terminal from the LTE network to the MF network .

Description

technical field [0001] The present invention relates to the field of measurement of wireless communication networks, in particular to a measurement method, base station and terminal of a wireless communication network. Background technique [0002] In the Licensed Assistant Access (LAA, Licensed Assistant Access) technology of the 3GPP standard organization, the carrier using the unlicensed frequency band adopts the physical layer technology that conforms to the LTE standard. In order for LAA and other devices in the unlicensed band (such as WiFi devices) to fairly occupy the channel of the unlicensed band and avoid mutual interference between the devices in the unlicensed band, the carrier physical layer of the LAA unlicensed band introduces a carrier sense technology similar to WiFi. Speaking (LBT, Listen BeforeTalk) mechanism. When the base station or the terminal detects that the unlicensed frequency band channel is occupied, that is, when the LBT fails, it stops sendin...

Problems solved by technology

[0008] However, after the introduction of MF access technology, the E-UTRAN measurement object information unit MeasObjectEUTRA cannot indicate whether the measurement object is for LAA neighbor cell measurement or MF neighbor cell measurement

Moreover, since the operating frequency band and frequency point of the MF base station are variable, the base station (including the MF base station and the LTE base station) may not know the operating frequency point of the adjacent MF base station, so the base station needs to instruct the UE to operate in the entire MF frequency band or part of the frequency band. However, currently MeasObjectEUTRA cannot instruct the UE to measure the channel quality of the MF cell on the whole or part of the frequency band
