Embodiment Construction

[0246] In order to achieve the purpose of the present invention, an embodiment of the present invention provides a method and device for determining channel state information. The UE obtains indication information, and the indication information is used to indicate that the base station has seized the first license-exempt spectrum resource; according to the acquired According to the indication information, determine a reference time point; according to the reference time point, determine a reference resource, the reference resource is used to measure the channel state of the channel corresponding to the first unlicensed spectrum resource that has been preempted; according to the Referring to resources, determining channel state information of a channel corresponding to the first license-exempt spectrum resource, and sending the determined channel state information to the base station.

[0247] In this way, in the case of opportunity to use license-exempt spectrum resources, the...

Abstract

Disclosed are a method and device for determining channel state information, comprising: a UE acquires indication information, determines a reference point in time on the basis of the indication information acquired, determines a reference resource on the basis of the reference point in time, determines, on the basis of the reference resource, channel state information of a channel corresponding to the first license-free spectrum resource, and transmits to the base station the channel state information determined. As such, with opportune use of the license-free spectrum resource, the UE determines in real-time the reference point in time on the basis of the indication information transmitted by the base station and determines a reference resource used for measuring a channel state of the channel corresponding to the license-free spectrum resource preempted by the base station, thus allowing flexible adjustment of the determined reference resource on the basis of the license-free spectrum resource preempted by the base station, increasing the precision in channel state information measurement, and effectively ensuring the efficiency of data transmission using the license-free spectrum resource.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for determining channel state information. Background technique [0002] Spectrum is the foundation of wireless communications. According to the latest international spectrum white paper released by the Federal Communications Commission (English: Federal Communications Commission; abbreviation: FCC), unlicensed or license-free (English: unlicensed) spectrum resources are greater than authorized or licensed (English: licensed) spectrum resources. [0003] At present, the main technology used on the license-free spectrum is Wireless Fidelity (English: Wireless Fidelity; abbreviation: WiFi), however, WiFi technology has advantages in mobility, security, quality of service (English: Quality of Service; abbreviation: QoS) and There are defects in dealing with multi-user scheduling at the same time. Therefore, applying Long-Term Evolution (En...
