Reporting method, a kind of CQI reporting device of FDD system based on flexible duplex and a kind of terminal.
Background technique
Current 5th Generation Mobile Communication System (5G) is just among the research of academia and industrial circle.Wherein super-intensive network
(Ultra-Dense Network, UDN) is an important technology of 5G.UDN refers in network deployment, for certain data
The scene (such as stadium, railway station Waiting Lounge, office space etc.) of demand greatly, more than data connection number, carries out super-intensive
Networking, the interval between access website may only have tens of rice.One technology that may be used under UDN scene is flexibly double
Work (Flexible Duplex), i.e., according to the demand of business, in FDD (Frequency Division Duplexing, frequency division
Duplex) uplink spectrum in system certain subframes on bearing downlink business.As shown in Figure 1, in uplink spectrum in UL subframe
The reasons why bearing downlink business, such way, is, in UDN scene, often will appear that downlink traffic is more (such as to be had more
Video, picture downloading), downlink resource is busy and the most of idle situation of ascending resource, uses flexible duplex technology can be with
The frequency spectrum resource for more effectively utilizing FDD system, promotes user experience.Flexible duplex technology is i.e. by certain subframes of uplink spectrum
It is used as downlink subframe, i.e., sends downlink data on the running time-frequency resource of these sub-frame of uplink.These, which are diverted, does lower line number
It is referred to as flexible sub-frame according to the sub-frame of uplink of transmission, keeps the sub-frame of uplink as transmitting uplink data, referred to as non-flexible subframe.
Usually in without using the flexibly FDD system of duplex, terminal can carry out corresponding downlink subframe in sub-frame of uplink
CQI (Channel Quality Indicator, channel quality information) is reported, however by sub-frame of uplink with after for downlink subframe,
It has there arises a problem that the CQI for carrying out corresponding downlink subframe on certain sub-frame of uplink originally is reported, but on these
