Background technology
In wireless communication technology, (for example the Node B of evolution is eNodeB to base station side, be called for short eNB) when using many antenna transmission data, can take the mode of spatial reuse to improve message transmission rate, promptly use identical running time-frequency resource in the different different data of aerial position emission at transmitting terminal, receiving terminal (for example subscriber equipment (UE, User Equipment)) also uses many antennas to receive data.Under single user's situation, the resource of all antennas is all distributed to same user, this user occupies the physical resource of distributing to base station side alone in a transmission intercal, this transmission means is called single user's multiple-input and multiple-output (SU-MIMO, Single User Multiple-Input Multiple-Out-put); Under multi-user's situation, the space resources of different antennae is distributed to different user, a user and at least one other user physical resource that the sharing base side is distributed in a transmission intercal, sharing mode can be space division multiple access mode or space division multiplexing mode, this transmission means is called multi-user's multiple-input and multiple-output (MU-MIMO, Multiple User Multiple-Input Multiple-Out-put), wherein the physical resource of base station side distribution is meant running time-frequency resource.Transmission system is if support SU-MIMO and MU-MIMO simultaneously, and eNB then needs to provide data under these two kinds of patterns to UE.UE need know that all eNB is for the used order (Rank) of these UE transmission MIMO data when SU-MIMO pattern or MU-MIMO pattern.Under the SU-MIMO pattern, the resource of all antennas is all distributed to same user, and the used number of plies of transmission MIMO data just equals eNB in the used order of transmission MIMO data; Under the MU-MIMO pattern, a corresponding user is transmitted total number of plies that the used number of plies is less than eNB transmission MIMO data, if carry out the switching of SU-MIMO pattern and MU-MIMO, eNB need be at the different transmission mode different control data of UE that sends a notice.
At Long Term Evolution (LTE, Long Term Evolution) in the system, reflection down physical channel state information (CSI, Channel State Information) relates to three partial contents: channel quality indication (CQI, Channel Quality Indication), pre-coding matrix indication (PMI, Precoding Matrix Indicator), order indication (RI, Rank Indicator).
CQI is for weighing the index of down channel quality quality.At third generation partner program (3GPP, 3rd Generation Partnership Project) in the 36-213 agreement, CQI represents with 0～15 integer value, represented different CQI grades respectively, different CQI correspondences modulation system and coding techniques (MCS, Modulation and Coding Scheme) separately, are divided into 16 kinds of situations, can adopt 4 bit informations to represent, as shown in table 1:
Table 1
CQI is an important indicator weighing data transmission quality, its sign be adopting the RI value as the transmission number of plies, and the code word of selecting the PMI indication that reports for use is during as precoding, the channel quality when carrying out the transmission of MIMO closed loop precoding according to the mode of agreement regulation.Therefore, CQI can not be independent of RI and PMI existence.
Carry out in the CSI deterministic process at UE in the correlation technique, for different channel state information reference signals (CSI-RS, Channel State Information-Reference Signal) port subclass, the uncontrollable PMI/RI feedback that has or not, the result can't select to obtain PMI/RI or obtain PMI/RI by feedback by reciprocity according to actual channel conditions, thereby cause to utilize the reciprocity and the feedback overhead that can't reduce system of time division duplex (TDD, Time Division Duplexing) system.Wherein, one or more transmission node of corresponding cooperative multipoint transmission (CoMP, a Coordinated Multiple Point Transmission and Reception) system of each CSI-RS port subclass or a distributing antenna system.

Embodiment
Basic thought of the present invention is: network side disposes the configuration signal to CSI-RS port subclass, and with reference signal and configuration signal notice UE; UE carries out channel measurement according to reference signal, determines channel condition information CSI according to the result of channel measurement; And according to the configuration signal of network side to channel state information reference signals CSI-RS port subclass, the CSI that carries out each CSI-RS port subclass respectively reports.
For making purpose of the present invention, technical scheme and advantage are clearer, and by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Fig. 1 is the flow chart of the channel condition information processing method of the embodiment of the invention, and as shown in Figure 1, the channel condition information processing method of this example may further comprise the steps:
Step S110, UE receives the configuration signal of network side; Wherein, described configuration signal comprises the PMI-RI-Report parameter of corresponding end openning collection.Wherein, if a port subclass disposes described parameter, then described port subclass disposes (configured with) PMI and RI report, otherwise described port subclass configuration (configured without) does not have PMI and RI report.A subclass of the set that all CSI-RS ports constitute in the configuration that described CSI-RS port subclass is a CSI-RS.Particularly, the set that N all CSI-RS ports constitutes in a CSI-RS configuration has m CSI-RS port subclass; Wherein, N is the positive integer greater than 1, and m is greater than 1 and smaller or equal to the positive integer of N.Described CSI-RS port subclass is two when above, does not comprise identical CSI-RS port in two above CSI-RS port subclass.The port numbers that plural CSI-RS port is occupied not simultaneously, described plural CSI-RS port is different CSI-RS port; Plural CSI-RS port has identical port numbers, shared physical resource not simultaneously, described plural CSI-RS port is different CSI-RS port; Wherein, described physical resource comprises at least a of following resource: time resource, frequency resource, sign indicating number resource.
Further, each CSI-RS port subclass can define by the configuration parameter of one group of high level, described one group of high-rise configuration parameter can be port number antennaPortsCount and resource distribution resourceConfig, and perhaps described one group of high-rise configuration parameter can be port number antennaPortsCount, resource distribution resourceConfig and sub-frame configuration subframeConfig.
Step S120, UE use the reference signal that receives to carry out channel measurement; Wherein reference signal one of comprises below with reference to signal at least at least: CSI-RS or public reference signal (CRS, Common Reference Signal).
Those skilled in the art are to be understood that, because it is prior art that UE utilizes reference signal to carry out channel estimating, the also non-technological difficulties of the realization of channel estimation technique, it is to realize easily that UE uses the reference signal that receives to carry out channel measurement, repeats no more it here and realizes details.
Step S130, UE determines CSI according to the result of channel measurement, and reports CSI according to configuration signal to network side.Comprise following dual mode particularly:
Mode one: if a port subclass disposes (configured with) PMI and RI, then UE reports the PMI and the RI information of described port subclass to network side, further reports PMI, RI and CQI; If a port subclass configuration does not have (configured without) PMI and RI, then UE does not report the PMI and the RI information of described port subclass to network side, further only reports CQI.
Mode 2: if the port number that port subclass disposes PMI and RI and described port subclass is greater than 1, then described UE reports the PMI and the RI information of described port subclass to network side, further reports PMI, RI and CQI; If a port subclass configuration does not have the port number of PMI and RI or described port subclass to equal 1, then described UE does not report the PMI and the RI information of described port subclass to network side, further only report CQI.
By above-mentioned steps, UE uses the channel measurement result to determine CSI, and reports, and has realized in the correlation technique using different configuration signals to have or not the feedback of PMI and RI information with control to different CSI-RS port subclass in the CSI deterministic process.Like this, can be so that a part of CSI-RS port subclass utilize the reciprocity of channel to determine PMI and RI, and do not need to feed back PMI and RI, only need a feedback CQI to get final product.Thereby realized that communication system has reduced CSI and reported expense under the prerequisite that guarantees service feature.Technical scheme of the present invention is particularly suitable for the TDD system.
Fig. 2 is the flow chart of another channel condition information processing method of the embodiment of the invention, and as shown in Figure 2, this example channels state information processing method may further comprise the steps:
Step S210, base station configuration is to the configuration signal of CSI-RS port subclass.
Wherein, described configuration signal comprises the PMI-RI-Report parameter of corresponding end openning collection.Wherein, if a port subclass disposes described parameter, then described port subclass disposes (configured with) PMI and RI report, otherwise described port subclass configuration (configured without) does not have PMI and RI report.A subclass of the set that all CSI-RS ports constitute in the configuration that described CSI-RS port subclass is a CSI-RS.Particularly, the set that N all CSI-RS ports constitutes in a CSI-RS configuration has m CSI-RS port subclass; Wherein, N is the positive integer greater than 1, and m is greater than 1 and smaller or equal to the positive integer of N.。Described CSI-RS port subclass is two when above, does not comprise identical CSI-RS port in two above CSI-RS port subclass.The port numbers that plural CSI-RS port is occupied not simultaneously, described plural CSI-RS port is different CSI-RS port; Plural CSI-RS port has identical port numbers, shared physical resource not simultaneously, described plural CSI-RS port is different CSI-RS port; Wherein, described physical resource comprises at least a of following resource: time resource, frequency resource, sign indicating number resource.Further, each CSI-RS port subclass can define by the configuration parameter of one group of high level, described one group of high-rise configuration parameter can be port number antennaPortsCount and resource distribution resourceConfig, and perhaps described one group of high-rise configuration parameter can be port number antennaPortsCount, resource distribution resourceConfig and sub-frame configuration subframeConfig.
Step S220, the base station sends to UE with above-mentioned configuration signal and reference signal.
Step S230, the base station receives result and PMI and the determined CSI of RI configuration signal from the use channel measurement of UE.Comprise dual mode particularly:
Mode one: if a port subclass disposes (configured with) PMI and RI, then network side receives only the PMI and the RI information of described port subclass, further receives PMI, RI and CQI; If a port subclass configuration does not have (configured without) PMI and RI, then network side receives the PMI and the RI information of described port subclass, further receives only CQI.
Mode 2: if the port number that port subclass disposes PMI and RI and described port subclass is greater than 1, then network side receives the PMI and the RI information of described port subclass, further also receives CQI information; If a port subclass configuration does not have the port number of PMI and RI or described port subclass to equal 1, then described network side receives the PMI and the RI information of described port subclass, further receives only CQI.
Pass through above-mentioned steps, base station configuration is corresponding to the PMI and the RI configuration signal of CSI-RS port subclass, and obtain UE and use the channel measurement result and be somebody's turn to do the CSI that determines corresponding to the PMI and the RI configuration signal of CSI-RS port subclass, realized in the correlation technique in the CSI deterministic process, used different configuration signals to have or not PMI and RI feedback with control to different CSI-RS port subclass.Like this, can be so that a part of CSI-RS port subclass utilize the reciprocity of channel to determine PMI and RI, and do not need to feed back PMI and RI, only need a feedback CQI to get final product.Thereby realized that communication system has reduced CSI and reported expense under the prerequisite that guarantees service feature.Technical scheme of the present invention is particularly suitable for the TDD system.

CP length adopts the CP length of non-Multicast Broadcast Single Frequency Network (MBSFN, Multicast/Broadcast Single Frequency Network) subframe;
Redundancy versions adopts redundancy versions 0 (RV0);
Come the transmission plan of (Assumed) PDSCH of given hypothesis according to the transmission mode of the current configuration of described UE;
If carry out channel measurement, need the ratio of the energy (EPRE, Energy Per Resource Element) of each resource element between given PDSCH and the CSI-RS according to CSI-RS;
If carry out channel measurement, need the ratio of the EPRE between given PDSCH and the CRS according to CRS.
About the definition of CSI reference resources, on frequency domain, the CSI reference resources defines with one group of downlink physical Resource Block, and the downlink physical Resource Block is corresponding on the CQI value frequency band corresponding of source; On time domain, the CSI reference resources defines with a descending sub frame; On the transport layer territory, the CSI reference resources defines with any RI and PMI, and CQI is a condition with RI and PMI.
Described CQI determines that method comprises, channel measurement may comprise following dual mode:
For a transmission mode, if a port subclass configuration does not have PMI and RI, UE carries out channel measurement based on CRS, if a port subclass disposes PMI and RI, UE carries out channel measurement based on CSI-RS.
For a transmission mode, for all port subclass, terminal UE is always carried out channel measurement based on CSI-RS.
