Description
Technical field
The present invention relates to the communications fields, in particular to a kind of non-periodic channel quality information（CQI）The side reported
Method, device and terminal.
Background technique
In order to provide a user the various businesses content such as voice, packet data, broadcast, cordless communication network is extensive
Deployment, in order to meet the growing communication quality of user and traffic rate demand, wireless communication technique（Wireless network）Constantly
Evolution development.Cordless communication network is from global system for mobile communications（Global System For Mobile
Communication, GSM）/ general wireless packet service system（General Packet Radio Service, GPRS）2nd
In generation, the/the 2.5 third generation mobile communication network evolved to Universal Mobile Communication System (Universal Mobile
Telecommunications System, UMTS) third generation mobile communications network.And frequency spectrum uses effect in order to better improve
Rate meets the wireless communication needs that user is skyrocketed through, third generation partner program（The 3rd Generation
Partnership Project, 3GPP）Tissue proposes the 4th third-generation mobile communication technology long term evolution on the basis of UMTS again
（Long Term Evolution, LTE）And its further evolution technology " senior long term evolution "（Long Term Evolution
Advance, LTE-A）.
To provide higher data rate to mobile subscriber, LTE-A proposes carrier aggregation technology（Carrier
Aggregation, abbreviation CA）, the purpose is to provide bigger broadband for the UE with respective capabilities, improve the peak rate of UE.
In LTE, the maximum downstream transmission bandwidth that system is supported is 20MHz, and carrier wave polymerization is by the component carrier of two or more
（Component Carriers, abbreviation CC）It is aggregating support and is greater than 20MHz, maximum is no more than the transmission bandwidth of 100MHz.
UE can pass through multiple component carriers after entering connected state simultaneously（Such as CC1 and CC2）It is communicated with base station, base station can be by aobvious
The configuration of formula is that UE specifies a principal component carrier wave according to protocol conventions（Primary Component Carrier,
PCC）, other component carriers are known as auxiliary component carrier（Secondary Component Carrier, SCC）.On PCC
Serving cell is known as main serving cell（Primary Cell, Pcell）, the serving cell on SCC is known as auxiliary serving cell
（Secondary Cell, Scell）.
In order to meet the performance indicator of LTE-A, performance requirement of the especially up to LTE-A to Cell Edge User, multiple spot
Cooperation（Coordinated Multi Point, CoMP）Transmission technology is suggested.CoMP transmission technology is seen as improving small
Area edge user performance effectively inhibits one of the important technology of inter-cell interference.Lte-a system can be increased by CoMP technology
Increase the covering of data rate, to improve the handling capacity of cell edge, further increases throughput of system.So-called CoMP refers to
The multiple eNB separated on geographical location（Evolved NodeB, evolved base station）, or claim multiple transmission nodes
（Transmission Point, TP）It participates in and the data of the same UE is transmitted.For this purpose, in the existing transmission mode of LTE system
1-9（Transmission Mode, TM）On the basis of, TM10 is specially devised for CoMP.
In LTE system, UE can reporting channel quality instruction（Channel Quality Indicator, CQI）So as to network
Side is reasonably dispatched, CQI have the period and it is aperiodic report, unless stated otherwise, it is all aperiodic that the CQI herein referred to, which is reported,
It reports.For the configuration that CQI is reported, before introducing CoMP, need to report the service of CQI according to the form configuration of bit map
Cell configures two triggering collection altogether for terminal and is collectively referred to as the first triggering set（Need to report the serving cell of CQI corresponding
Bit is set as 1, other are set as 0）With the second triggering set（Need to report the corresponding bit of the serving cell of CQI to be set as
1, other are set as 0）, network side can be corresponded to by physical layer signaling indicating terminal to report CQI request, signaling content in following table
One column, such as instruction report ' 10 '（From following table it can be seen that corresponding first triggering set）CQI when, terminal search first touching
It is configured with the cell for needing to report CQI in hair set and reports the CQI of these cells, the case where instruction reports ' 11 ' is with ' 10
When the CQI of ' similar, when instruction reports ' 01 ', needing to report the cell of CQI is to meet the cell of the following conditions simultaneously：Cell
The resource for reporting CQI is assigned, and the aperiodic CQI trigger value of cell is ' 01 '.
Table 7.2.1-1A:It is asked in the CSI that the specific region of search UE is used for the PDCCH/EPDCCH with uplink DCI format
Seek domain (CSI Request field for PDCCH/EPDCCH with uplink DCI format in UE specific
search space)
When introducing CoMP, each serving cell must be according to channel state information treatment progress（Channel State
Information, CSI-process）CQI is configured, each cell can configure multiple CSI-process, each CSI-
Process configures individual aperiodic CQI trigger value, aperiodic CQI trigger value can be ' 01 ', ' 10 ', ' 11 ', network
Side can correspond to first row in following table by physical layer signaling indicating terminal to report CQI request, signaling content, for example, instruction report as
‘10'（From following table it can be seen that corresponding first triggering set）CQI when, terminal searches the CSI- of each serving cell
The CQI of process is configured, and the CSI-process for the serving cell that aperiodic CQI trigger value is ' 10 ' requires to carry out on CQI
The case where report, instruction reports ' 11 ' with ' 10 ' similar, when instruction reports ' 01 ' CQI when, the money for reporting CQI is assigned
The serving cell in source, and the aperiodic CQI trigger value of serving cell configuration is also that ' 01 ' just needs to report the serving cell
Under all CSI-Process CQI.
Table 7.2.1-1B:It is asked in the CSI that the specific region of search UE is used for the PDCCH/EPDCCH with uplink DCI format
Ask domain（CSI Request field for PDCCH/EPDCCH with uplink DCI format in UE specific
search space）
In addition, in above-mentioned physical layer signaling indicating terminal to report CQI request, table 7.2.1-1A and table can only be corresponded to
A table in 7.2.1-1B.When terminal has multiple serving cells of connection, all no configuration CoMP simultaneously, CQI request is just
Corresponding table 7.2.1-1A, when multiple serving cells are all configured with CoMP, CQI request just corresponds to table 7.2.1-1B, when multiple clothes
Business cell part is configured with CoMP, and CQI request just corresponds to table 7.2.1-1B, then can not correspond to table without the cell for configuring CoMP
7.2.1-1B CQI can not be just reported, network side can not reasonably dispatch these serving cells.
