I1: the CSI of same antenna port is belonged on different carrier waves.For example the CSI on different carrier waves on antenna port 1 is classified as the same CSI set.
Certainly, above-mentioned a variety of CSI rules of classification can also be grouped using in combination of any two or more mode, and the present invention is without limitation.
Different instruction rules can also be used in configuration for the CSI request instruction in above-mentioned steps, indicating different CSI set, such as can be any one of following:
A2: it polymerize for the polymerization of such as 32 carrier waves for big quantity carrier wave, at least three bit can be used to realize that more CSI request instructions are mapped to different CSI set, the CSI request instruction that 3 different bit informations indicate different can be used in this way, indicate first CSI set etc. for example, by using 011；
Control information can be used in b2:CSI request instruction, concretely the different-format (format) of Downlink Control Information DCI indicates, such as the different formats such as 1D, 2A, 1C in DCI format and different types of CSI set can be mapped, namely indicate that different CSI requests indicates using different DCI formats；
C2:CSI request instruction can be used to characterize the information of the information of uplink scheduling or descending scheduling and indicate, to distinguish different CSI set.Such as indicate that a corresponding CSI gathers when uplink scheduling with 00, indicate that a corresponding CSI gathers when descending scheduling with 01；
Modulation and coding strategy (the Modulation and Coding Scheme of DCI carrying can be used in d2:CSI request instruction, MCS it) indicates, indicate that different CSI set or different coding modes indicate different CSI set for example, by using different modulation systems；
The carrier identification that carrier wave of the base station for sending Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) or enhancing Physical Downlink Control Channel ePDCCH (enhanced Physical Downlink Control Channel) can be used in e2:CSI request instruction indicates.For example, in the polymerization of 32 carrier waves, by the way of making an appointment between base station and UE or base station configuration, using being sent out on carrier wave 1, carrier wave 2 and carrier wave 3 PDCCH or ePDCCH is sent to map different CSI set respectively, such UE can determine different CSI set according to the carrier information for receiving PDCCH or ePDCCH；
F2:CSI request instruction can be used and indicate the mark of the PDCCH or ePDCCH group after PDCCH or ePDCCH grouping, specifically after to PDCCH or ePDCCH grouping, it then indicates that different CSI requests indicates using the mark of the mark of different PDCCH groups or ePDCCH group, and then is mapped to different CSI set；
The mark for the group that the schedulable carrier wave of PDCCH or ePDCCH can be used in g2:CSI request instruction indicates, due to the different schedulable different carrier waves of PDCCH or ePDCCH, different CSI request instructions can be indicated to belong to the group of the scheduling carrier wave of same PDCCH or ePDCCH in this way, and then be mapped in different CSI set；
The mark that wave band belonging to PDCCH can be used in h2:CSI request instruction indicates different CSI request instructions, and then the CSI on the carrier wave for belonging to different-waveband can be classified as to different CSI set and mapped with CSI request instruction；
I2:CSI request indicates that the quantity for the resource that dispatching uplink is sent or downlink is sent or time-domain position or frequency domain position can be used to indicate, to indicate different CSI request instructions, and then is mapped to different CSI set.
DCI can be used in j2:CSI request instruction indicates in public search space or the search space UE, to imply different CSI request instructions, and then is mapped to different CSI and gathers.For example, if UE indicates the CQI of all carrier waves of mapping in the transmission request of the received CSI of public search space.
Certainly, the expression rule of the above a variety of CSI requests instruction can also be combined using two or more any rule to realize.
Can also use preconfigured mode or base station to carry out the mode of network configuration to UE after using the preconfigured mode CSI that perhaps base station is configured with for UE different CSI request instructions to the mode that UE carries out network configuration and different CSI aggregate types has to gather and indicate for UE configuration CSI request mapping relations between CSI aggregate type.The mapping relations can be to be mapped one by one between CSI request instruction and CSI aggregate type, is also possible to one-to-many mapping, many-one mapping or multi-to-multi mapping etc..
Then, base station can use different CSI request instructions to trigger aperiodic CSI and report, the UE just CSI different to base station feedback according to mapping relations.
For example, it is combined with above-mentioned rule a1 and rule e2, when the carrier identification of carrier wave of the CSI request instruction in base station using base station for sending PDCCH indicates, CSI aggregate type is that first CSI set of the high-rise configuration of triggering reports, when first CSI gathers the CSI that corresponding CSI is the same carrier wave set after being grouped carrier wave according to carrier identification, base station may make to send PDCCH on different carrier waves and indicate to trigger the CSI of different carrier wave and different variable numbers.
Such as UE can support 32 carrier waves polymerize when, base station sends PDCCH triggering UE on carrier 1 and the request of aperiodic CSI is reported to indicate to indicate that UE needs to report first CSI set, namely CSI aggregate type is first CSI set, first CSI set is the CSI of all 32 carrier waves, sending PDCCH triggering UE on carrier 2 reports the request of aperiodic CSI to indicate to indicate that UE needs to report second CSI set, namely CSI aggregate type is second CSI set, second CSI collection is combined into the CSI for being identified as 1~16 this preceding 16 carrier wave, PDCCH triggering UE is sent on carrier wave 3 reports the request of aperiodic CSI to indicate to indicate that UE needs that third CSI is reported to gather, namely CSI collection class Type is third CSI set, and the third CSI collection is combined into the CSI for being identified as 17~32 this rear 16 carrier wave.For this citing, CSI request is indicated can be as shown in table 1 with the mapping relations of CSI aggregate type.
Table 1
Wherein, ' 00 ' and ' 01 ' indicating mode can be same as the prior art, respectively indicates and does not trigger the CSI that UE reports aperiodic CSI and triggering UE reporting uplink carrier wave, ' 1 ', ' 2 ', ' 3 ' indicate the mark of carrier waves, different carrier identifications and different CSI compound mappings.
Again for example, it is combined with above-mentioned rule b1 and rule a2, for big quantity carrier wave polymerize the polymerization of such as 32 carrier waves, after the corresponding CSI collection of CSI aggregate type is combined into different community according to different physical uplink link control message PUCCH groupings are belonged to, belong to the CSI of the descending carrier of the cell of the same PUCC group, when indicating to realize that more CSI request instructions (CSI request field) are mapped to different CSI aggregate types using at least three bit with CSI request, the bit number of the CSI request field in increase DCI can specifically be passed through, for example increase to 3 bit from 2 bit, to indicate that triggering the carrier wave in different PDCCH groups reports CSI.Such as 011 expression base station triggers UE report first CSI set to report, first CSI gathers the carrier wave in corresponding first PUCCH group, 100 expression base station triggers UE report second CSI set to report, second CSI gathers the CSI of the carrier wave in corresponding second PUCCH group, 101 expression base station triggers UE report third CSI set to report, and the CSI that the third CSI gathers the carrier wave in corresponding third PUCCH group is reported.
Again for example, it is combined using regular c1 and rule h2, belong to the CSI of the carrier wave of the same band or the same band combination after the corresponding CSI collection of CSI aggregate type is combined into and is grouped carrier wave according to different wave bands, when CSI request instruction indicates different CSI request instructions using the mark of wave band belonging to PDCCH, if CSI request is designated as the mark of a certain wave band, indicate that base station triggers UE reports the CSI of the carrier wave of the wave band to report.
The embodiment of the invention provides a kind of report methods of channel state information, it can be used for big quantity carrier wave polymerization, the control information that base station is sent is received by UE, the control information is indicated including the first CSI request, and the representation of first CSI request instruction is unlike the prior art, it may include 3 bit or other instruction information, the UE is indicated according to the CSI request and the mapping relations of the CSI aggregate type obtain the first CSI aggregate type corresponding with the first CSI request instruction, wherein, the CSI request instruction is used to indicate the UE and reports aperiodic CSI, here CSI aggregate type corresponding CSI set can there are many, such as by different carrier waves, different-waveband, CSI set after different PUCCH groupings, then UE is to the base It stands and sends CSI measurement report, the CSI measurement report includes CSI set corresponding with CSI request instruction, so, with the prior art The 4 kinds of CSI requests indicated using 2 bit are indicated compared with 4 kinds of CQI compound mappings, technical solution of the present invention is gathered using a variety of CSI request indicating modes and a plurality of types of CSI, the quantity of CSI request instruction and the quantity of different types of CSI set can be increased, in this way for the polymerization of the carrier wave of big quantity, so that reporting for CSI is more flexible.
Such as the polymerization of 32 carrier waves, compared to the prior art using 4 kinds of CSI request instructions, preceding 2 kinds of instructions, which respectively indicate, does not trigger the CQI that UE reports aperiodic CQI and reporting uplink carrier wave, latter two instruction respectively with first CQI compound mapping and second CQI compound mapping, first CQI set and second CQI set will include excessive CQI, but this will cause UE that uplink PUSCH carry load is overweight, uplink PUSCH covering is reduced, but if when indicating more CQI set using 3 bit in technical solution of the present invention, CQI may make to report in a variety of set, base station reports different CSI to gather according to required triggering UE, meeting is so that uplink PUSCH carrying is more balanced；If the prior art includes less CQI using each CQI set, meeting prevent base station from learning the immediate status of local channel, preferred channel status cannot be obtained, but the present invention uses a plurality of types of CQI, base station can learn more channel state informations according to needed for, to make communication system preferably adapt to current channel condition, the communication for high reliability high-speed is provided safeguard in multi-antenna systems.
