Fig. 1-3 shows the embodiment of the CSI-RS antenna ports distribution in downlink resource blocks (RB), is described in detail Which resource element (RE) in subframe is with which CSI-RS antenna port associated.As shown in figure 1, according to 3GPP specifications The downlink resource blocks 100 of version 10 include multiple OFDMs in multiple subcarriers 110 and time domain in frequency domain (OFDM) symbol 120.For each subcarrier k and each OFDM symbol l, resource block 100 has resource element 130.

As illustrated, for downlink resource blocks 100 each resource element 130 (i.e. for each subcarrier and OFDM symbol combines k＆l), define certain types of RE.For example, the resource element at the subcarrier 0＆OFDM symbols 0 of resource block 100 Element 130 is defined as physical downlink control channel (PDCCH) symbol, in other resource elements 130 of OFDM symbol 0 to 2 Most of be also defined as PDCCH symbols.Meanwhile the resource element 130 at subcarrier 2,5,8 and 11＆OFDM symbols 0 and 1 It is defined for cell specific reference symbol (CRS) symbol of each port；Money at subcarrier 3,7 and 11＆OFDM symbols 3 Source element 130 is defined as demodulation reference mark (DMRS) symbol according to version 8；And subcarrier 0-1,5-6 and 10-11＆ Resource element 130 at OFDM symbol 5-6 and 12-13 is defined as the DMRS according to version 9 and version 10.Remaining resource element Many resource elements in element 130 are defined as physical down link sharing channel (PDSCH) symbol.

Some resource elements 130 are defined as CSI-RS symbols.More specifically, at all Zi Zaibo ＆OFDM symbols 9-10 Resource element and subcarrier 2-3 and 8-9＆OFDM symbol 5-6 and 12-13 at resource element be defined as CSI-RS symbol Number.Fig. 1 depicts the multiple CSI- for being defined as CSI-RS symbols of those combinations for subcarrier 110＆OFDM symbols 120 RS resource elements 150.

Each CSI-RS element 150 is listed as 0 or 1, and the antenna port of the eNB with sending resource block 100 15 or 16 is corresponding.Similarly, Fig. 2 depict be listed as 0 to 3 and with send eNB antenna port 15 to 18 it is corresponding Multiple CSI-RS elements 260, and Fig. 3 depict be listed as 0 to 7 and with send eNB antenna port 15 arrive 22 corresponding multiple CSI-RS elements 370.

Fig. 1 depicts the CSI-RS element 150 with 1 port or 2 terminal port antennaes, and Fig. 2 is depicted and 4 port days The associated CSI-RS element 260 of line, and Fig. 3 depicts the CSI-RS element associated with 8 terminal port antennaes 370.ENB can be sent to correspondingly UE for 1 eNB antenna port, 2 eNB antenna ports, 4 eNB antenna ports, Or the CSI-RS symbols of the associated radio communication channel of 8 eNB antenna ports.

Antenna port is logical construct, opposite with eNB or UE physical antenna.Therefore, one group of orderly antenna port can To correspond to one group of eNB antenna in a variety of ways.Fig. 4-6 shows the embodiment of eNB antennas and antenna port configuration, Yi Jixiang The CSI-RS antenna ports distribution answered.(CSI reference signals can using be numbered as 15 to 22 antenna port 1 port, Sent on 2 ports, 4 ports and 8 terminal port antennaes；Correspondingly, in fig. 1-3, the associated money of CSI-RS symbols will be carried Source element is numbered from 0 to 7.In figs. 4-6, associated eNB is numbered from 15 to 22.Volumes of the eNB from 15 to 22 Number reflect the numbering of CSI-RS configurations (this will be discussed further below).

For example, Fig. 4 depicts eNB antenna configurations 410 and the corresponding antenna port for 8 port eNB antennas configures 416.Antenna configuration 410 includes multiple first antennas 412 with the first polarization and multiple second antennas with the second polarization 414, wherein, the second polarization orthogonal is in the first polarization.The antenna 414 of first antenna 412 and second configures 416 quilts according to antenna port Each eNB antenna ports are mapped to, antenna port configuration 416 shows that eNB antenna ports 15-18 corresponds to first antenna 412 And eNB antenna ports 19-22 corresponds to the second antenna 414.Therefore, corresponding to eNB antenna ports 15-18 antenna have with Corresponding to the polarization of eNB antenna ports 19-22 antenna orthogonal.Corresponding resource block 400 depicts carrying and each eNB antennas The RE of the associated CSI-RS symbols in port is to 420 (each RE is to being two adjacent OFDM symbols in a subframe).

In Fig. 4, all antenna ports associated with 8 antenna channels both correspond to carry RE pairs of CSI-RS symbols 420.Single RE is to 420 antennas for corresponding to identical polarization.Therefore, if isolation uses, RE would not allow for aligning to 420 Poliarizing antenna is handed over to carrying out CSI-RS measurements.However, due to across the antenna port 15-22 of CSI-RS for 8 antenna channels, and Because the eNB antenna corresponding with antenna port 15-18 and antenna port 19-22 is by cross polarization, therefore carry CSI-RS symbols Number RE will allow 420 to the cross-polarized antennas in 8 antenna channels to carry out CSI-RS measurements.This be probably it is favourable, Because the channel condition information measurement of the CSI-RS symbols sent by cross-polarized antennas can produce more preferable channel performance.

On the contrary, Fig. 5 depicts eNB antenna configurations 510 and the corresponding antenna port for 4 port eNB antennas configures 516.However, being different from antenna configuration 410, antenna configuration 510 only includes multiple first antennas 512 with the first polarization, but Do not include with the second antenna 514 with the second of the first polarization orthogonal the polarization.First antenna 512 configures according to antenna port 516 are mapped to each antenna port.Based on codebook design principle, the antenna port of antenna port configuration 510 is mapped first To with a kind of antenna of polarization, be then mapped into the antenna with another kind polarization-in this case this represent only with A kind of antenna of polarization.Corresponding resource block 400, which depicts, carries the CSI-RS symbol associated with each eNB antenna ports RE is to 520.

Because antenna port 15-18 is only mapped to first antenna 512, therefore with carrying the RE of CSI-RS symbols to 520 Corresponding antenna port would not allow for the cross-polarized antennas for 4 antenna channels to carrying out CSI-RS measurements.This may It is unfavorable, because the channel condition information measurement of the CSI-RS symbols sent by the antenna of non-cross polarization may cause suboptimum Channel performance.

The embodiment that Fig. 6 describes has the corresponding antenna of eNB antenna configurations 610 and the 4 port eNB antennas for replacement Port configuration 616.Here, antenna configuration 610 include with first polarization two first antennas 612 and with first polarize Two the second antennas 614 of the second orthogonal polarization.Because antenna port 15-18 is mapped to first antenna 612 and orthopole Both the second antennas 614 changed, and surveyed because the CSI-RS symbols sent by these antenna will be used for channel condition information Amount, therefore the embodiment can advantageously produce the more preferable performance of the radio communication channel associated with 4 port eNB antennas.

However, the antenna ports associated to 620 with the RE in corresponding resource block 400 have with for 4 ends in Fig. 2 The CSI-RS antenna ports of mouth antenna distribute inconsistent port assignment.Based on Fig. 4-6, it would be preferable to support more flexible antenna port The new more flexible CSI-RS agreements of distribution, which can advantageously facilitate, establishes higher-quality radio communication channel.

New more flexible CSI-RS agreements can also advantageously adapt to distribute to more appropriate eNB antenna resources and spy Determine the radio communication channel of UE formation.Fig. 7 shows the various embodiments of antenna configuration.Antenna configuration 710 is 16 for eNB Aerial array, wherein, all 16 antennas are mapped to the antenna port for a radio communication channel.On the contrary, in day In line configuration 720, only 12 antennas in 16 aerial arrays are mapped to the antenna port of radio communication channel.Antenna configuration 730 and 740 show two different embodiments, wherein, 8 antennas of 16 aerial arrays are mapped to radio communication channel Antenna port.More specifically, in antenna configuration 730,8 antennas in a row of 16 aerial arrays are mapped to radio communication 8 antenna ports of channel, and in antenna configuration 740,4 antennas of each row in two row are mapped to radio communication 8 antenna ports altogether of channel.New more flexible CSI-RS agreements can be promoted remaining day based on eNB needs Line distributes to one or more other radio communication channels.

New more flexible CSI-RS agreements can also advantageously support FD-MIMO, this may need to be adapted to azimuth and Both elevations angle.Fig. 8 shown using FD-MIMO beam formings the eNB embodiment that is communicated with multiple UE, and generally Available for the eNB antennas pair typically transmitted and available for the eNB antennas pair being transmitted to particular UE.At Fig. 8 top, eNB 800 are depicted as having been set up the radio communication channel with UE 822, UE 824, UE 826 and UE 828, these channel radios Believe that channel has the different azimuths and the elevation angle relative to eNB 800.

In Fig. 8 bottom, beam pattern 840 is depicted available for the various antennas that typically transmit to 842, you can for by ENB 800 carries out the various antennas of beam forming to 842.Antenna can be correspondingly used as one or more 1 ports, 2 ends to 842 Mouth, 4 ports or 8 ports or the part of 16 terminal port antennaes.Similarly, beam pattern 850 depicts each available for typically transmitting Kind antenna further depict various antennas to 854 to 852, and the antenna cannot be only used for typically transmitting to 854, and more have It is desirably used for being formed and particular UE (for example, UE 822) by creating the FD-MIMO downlinks of beam forming by eNB 800 Radio communication channel.More specifically, antenna may more hold promise for the side based on UE 822 relative to eNB 800 to 854 Parallactic angle and the elevation angle form the radio communication channel with UE822.Therefore antenna can be used for forming 1 for eNB 800 to 854 Port, 2 ports, 4 ports, 8 ports or 16 terminal port antennaes, for being communicated with UE 822.

Fig. 9-10 is shown available for the eNB antennas pair typically transmitted and available for eNB days be transmitted to particular UE The embodiment of line pair, and corresponding CSI-RS antenna ports.Fig. 9 shows beam pattern 840 and available for the day typically transmitted Line to 842, and corresponding resource block 900 include can be used for sending for antenna to 842 CSI-RS symbols RE to 942. In Figure 10, beam pattern 850 is shown available for the antenna that typically transmits to 852, and be also show and can be more preferably used for shape Into the radio communication channel with UE 822 antenna to 854.Corresponding resource block 900 includes can be used for sending being directed to antenna pair The RE of 852 CSI-RS symbols to 952, wherein, RE to 954 correspond to antenna to 854.New more flexible CSI-RS agreements can To advantageously facilitate the use to the antenna pair for supporting FD-MIMO may be more suitable for.

Therefore new more flexible CSI-RS agreements can support increasing port.New agreement can also be supported pair The more flexible distribution of antenna port, this can produce the channel performance more optimized, and be adapted to more appropriate eNB days Line resource allocation gives the radio communication channel of particular UE formation.
