For example, the network equipment receives all or part of CSI that UE lateral roots obtain according to CSI-RS measurements, is detected in conjunction with itself The corresponding uplink channel status information of part uplink sending port that SRS is obtained；It is corresponding that its is calculated in CSI progress reciprocity Uplink channel status information is integrated above-mentioned two parts to obtain user equipment whole uplink channel status information；

Correspondingly, the network equipment equally receives the CSI that UE is reported and detection SRS；The portion of itself is determined according to CSI Divide downlink channel condition information；The testing result progress that SRS is obtained again is mutually disposable, under obtaining corresponding to the section ports Row channel state information；The downlink channel condition information of network equipment whole is obtained after two parts synthesis.

It should be pointed out that the above method, which is particularly suitable for TDD system uplink and downlink, has the scene of reciprocity.Above-mentioned CSI Acquisition methods are particularly suitable for Distributed T RP scenes, which can be further simplified as matrix in block form.It is above-mentioned CSI acquisition methods are particularly suitable for the scene that channel variation comparatively fast needs quick obtaining whole CSI, such as to time delay and transmission rate It is required to higher real time business.

A kind of example of the present embodiment, referring to Fig. 2：

Assuming that uplink and downlink channel has reciprocity, farther out, wave beam managed the TRP1 and TRP2 distances under the same cell Journey determines the best wave beam that sends and receives between TRP1 and TRP2 and UE to one-to-one correspondence, i.e. TRP1CSI-RS transmission antennas Port 0,1 and TRP2CSI-RS transmission antennas port 2,3 is corresponded with UE reception antennas port 0-4 respectively, and UE SRS are sent Antenna port 0-4 and TRP1 reception antennas port 0,1 and TRP2 reception antennas port 2,3 corresponds respectively.

It is limited to the transmitting capacity of UE, UE is only capable of sending the SRS based on wave beam forming on 2 antenna ports simultaneously.For Quickly whole channel CSI information, network side are configured SRS in a uplink symbol of a time slot and are sent with port 0 and 1, together When a downlink symbol in the time slot in configuration CSI-RS sent with port 2 and 3, as shown in Figure 2.UE measures CSI-RS simultaneously The part CSI measured on reception antenna port 2 and 3 is reported, the characteristic value and feature vector of local channel are included.

Network side receives the part CSI that the sides UE report, and merges generation with obtained SRS channel informations itself are measured Whole CSI, and further obtain layer mapping, modulating-coding and precoding mode.

The example two of the present embodiment, as shown in figure 3, including：

5G high-frequency mobiles communicate in TDD system, it is assumed that there is uplink and downlink channel reciprocity, wave beam management process to determine To corresponding, i.e. TRP CSI-RS transmission antennas port 0-7 and UE connects the best wave beam that sends and receives between TRP1 and UE It receives antenna port 0-7 to correspond, UE SRS transmission antennas port 0-7 and TRP reception antennas port 0-7 is corresponded respectively. It is limited to the transmitting capacity of UE, UE is only capable of sending the SRS based on wave beam forming on 4 antenna ports simultaneously.It is quickly whole Channel CSI information, network side are configured SRS in one or more uplink symbols of a time slot and are sent with port 0-4, while Configuration CSI-RS is sent with port 4-7 in one or more downlink symbols in the time slot, as shown in the figure.UE measures CSI-RS simultaneously The part CSI obtained in the 4-7 measurements of reception antenna port is reported, the characteristic value and feature vector of local channel are included.Network side It receives the part CSI that UE sides report, and whole CSI is generated with itself measuring obtained SRS channel informations and merging, go forward side by side one Step obtains layer mapping, modulating-coding and precoding mode.

The TRP managed by this exemplary wave beam sends wave beam and UE receives the correspondence between wave beam and closed The CSI-RS and SRS of reason are configured, and can not only improve the efficiency of CSI acquisitions, and then promote the validity of data transmission, can be with Reduce the expense of CSI-RS and SRS.

Further, the present embodiment can be additionally used in the following 5G high-frequency mobiles communication TDD system CSI quick obtainings, it can also be used to The following 5G high-frequency mobiles communication system reports channel piecemeal CSI for more times.Especially when sending port and receiving port can not one When one matching, it can be grouped and repeatedly measure and reported.It is to be herein pointed out being configured each time When, it can transmission and reception of the more transmission-reception ports of configuration as much as possible to progress reference signal.

Specifically：Further include in the configuration information：The reception downlink reference signal pair of at least one set of downlink reception port The running time-frequency resource and receiving time information answered；

The method further includes：

The downlink reception port of the user equipment is grouped；Wherein, include in different downlink reception port sets Downlink reception port is at least partly different；And whole downlink reception port sets cover N number of downlink reception port；

The configuration information further includes：At least one set of uplink receiving port receives the corresponding time-frequency money of uplink reference signals Source and transmission time information；

The uplink reference signals for receiving the user equipment and being sent by M uplink sending port, including：

When the uplink sending port quantity of the user equipment is less than the uplink receiving port number of the network equipment, The uplink receiving port of the network equipment is grouped；Wherein, the uplink receiving end for including in different uplink receiving ports Mouth is at least partly different；And whole uplink receiving port sets cover whole uplink receiving ports of the network equipment；

The matching of uplink sending port is carried out for each group of uplink receiving port；

Based on the corresponding running time-frequency resource of uplink reference signals and transmission time information, at least once by different upper Row receiving port group receives the uplink reference signals that the user equipment is sent.

For example, two groups that 32 receiving ports of the network equipment are divided into, first reception period passes through first group of reception Port receives uplink reference signals, is measured by the network equipment；Second receives the period by second group of port reception uplink ginseng Signal is examined, then the network equipment obtains the channel state information of this 32 receiving ports.

In addition, 16 receiving ports of the network equipment correspond to different uplink receiving ports within the two reception periods, Configuration information can be first passed through in advance be sent to user equipment；It is also to be appreciated that the corresponding transmission of two sending cycles And the matching relationship and the time point information in each reception period of receiving port can be sent to use by configuration information Family equipment.

As it can be seen that by using said program, it will be able to be configured to each port of user equipment, to determine user equipment The uplink sending port of downlink reception port and transmission uplink reference signals for receiving downlink reference signal；Then it connects The downlink port channel state information detected for receiving user equipment to report, the uplink sending port determined in conjunction with itself are corresponding Channel state information finally determines the downlink channel condition information of the network equipment, and/or determines the upper of the user equipment Row channel state information.So, it will be able to the more comprehensive channel state information of user equipment is quickly obtained, to ensure that The communication quality and communication efficiency of system.
