Problems solved by technology

[0004] Since different subcarrier intervals correspond to different OFDM symbol lengths, in the NR system, if the terminal measurement duration is still in accordance with the above configuration in the LAA system, it may cause the terminal to follow a fixed interval under different subcarrier intervals. The length of the OFDM symbol determines the terminal measurement duration and sampling point during channel measurement, which makes the terminal measurement duration and sampling point deviate, resulting in inaccurate measurement results

Embodiment Construction

[0032] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0033] First of all, the application scenario of the present disclosure is described, the rapid growth of mobile broadband services leads to an increasingly strong demand for frequency spectrum in the operator's cellular network. At present, the spectrum of the cellular network is mainly used in the form of dedicated spectrum, that is, the spectrum is unique to a certain network. Although dedicated spectrum for exclusive use is more efficient, it is expensive and the total amount of spectrum is limited. On the other hand, unlicensed spectrum has attracted increasing attention from operators due to its abundant available bandwidth and low licensing fees.

Abstract

The present disclosure relates to a method and apparatus for channel measurement, a terminal, a base station, and a storage medium, the method comprising: receiving a received signal strength indicator RSSI measurement timing configuration RMTC parameter transmitted by the base station; the RMTC parameter including indicator information of at least one subcarrier spacing, and terminal measurementduration corresponding to the indicator information, the different indicator information being corresponding to different terminal measurement duration; determining target terminal measurement duration corresponding to at least one target subcarrier spacing to be measured according to the indicator information of at least one subcarrier spacing and the terminal measurement duration corresponding to the indicator information; performing channel measurement according to the target terminal measurement duration.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular, relates to a channel measurement method, device, terminal, base station, and storage medium. Background technique [0002] In the LAA (Licensed-Assisted Access) system, it is usually necessary to assist the base station in channel selection through RSSI (Received Signal Strength Indicator) and channel occupancy reported by the terminal. The base station can configure The RMTC parameter (RSSI measurementTiming Configuration, measurement timing configuration) measured by the terminal, the RMTC parameter includes the terminal measurement duration indicating the terminal measurement, for example, the terminal measurement duration may be a set of terminal measurement duration {1 OFDM (Orthogonal Frequency Division Multiplexing , Orthogonal Frequency Division Multiplexing) symbols, 14 OFDM symbols, 28 OFDM symbols, 42 OFDM symbols, 70 OFDM symbols}, the base station sends the confi...
