BACKGROUND I. Field [0002] The following description is intended for wireless communications. II. Background [0003] Wireless communication systems are widely used in the field of communication, data, and so on. These systems may be multiple-access systems (eg bandwidth and transmit power). Long Term Evolution (LTE) systems, and orthogonal frequency division multiple access (CDMA) systems; (OFDMA) systems.

Generally, wireless multi-access communication systems can be used for multiple wireless terminals. Each terminal communicates with one or more base stations via the forward and reverse links. The forward link (or downlink) is the link to the terminals to the terminals. A single-in-one-out-multiple-in-multiple-in-multiple-in-multiple-out () system.

The ΜΙΜΟ system employs multiple (Nj) transmit antennas and multiple (NR) receive antennas for data transmission. The channel formed by the NTtransmit and NR receive antennas may be decomposed into Ns <min {A / r, NR}. Each of the Ns independent channels is a dimension. The ΜΙΜΟ system can provide improved performance (eg, higher throughput and / or higher reliability) if the additional transmit and receive antennas are utilized.

[0006] In addition, a base station is a mobile terminal. Reference signals are typically a priori to a receiver. The receiving device may also be used as a reference signal. While reference signals may be used as a reference, a signal may be used as a signal. Wireless data bandwidth, there is a greater demand for existing data signals. Additionally, the assignment is a reference signal or data signals. Additionally, new reference signals may be used to transmit data transmissions.

Various aspects are now described with reference to the drawings. In the following, the Commission shall submit a report to the Commission. It may be evident, however, that they are practically without these specific details. In other instances, well-known structures and devices are shown in block diagrams.

The Division of Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Frequency Division Multiple Access (FDMA) networks, Orthogonal FDMA (OFDMA) networks , Single-Carrier FDMA (SC-FDMA) networks, etc. Are often used interchangeably. The CDMA network may be implemented by radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband-CDMA (W-CDMA) and Low Chip Rate (LCR). cdma2000 covers IS-2000, IS-95 and IS-856 standards. The TDMA network may be implemented as a Global System for Mobile Communications (GSM). An OFDMA network may be implemented by radio technology such as Evolved UTRA (E-UTRA), IEEE 802.11, IEEE 802.16, IEEE 802.20, Flash-OFDM®, etc. UTRA, E-UTRA, and GSM are part of the Universal Mobile Telecommunication System (UMTS). Long Term Evolution (LTE) is an upcoming release of UMTS that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE are described in the 3rd Generation Partnership Project (3GPP). cdma2000 is described in "3rd Generation Partnership Project 2" (3GPP2). These radio technologies and standards are known in the art. For clarity, LTE terminology is used in much of the description below.

Single carrier frequency division multiple access (SC-FDMA) utilizes single carrier modulation and frequency domain equalization. SC-FDMA signal has a lower peak-to-average power ratio (PAPR) because of its inherent single carrier structure. Long Term Evolution (LTE) for 3GPP.

It is to be understood that the present invention relates to a method of signaling and signaling (CSI-RS) and muting technology. However, one aspect of the present invention will be appreciated by one of skill in the art.

Also, various combinations of antenna ports and transmission resource assignments are depicted in FIGs. 3 to 13 using the resources (or time) along the horizontal direction and frequency (or sub-carrier index) along the vertical direction. Additionally, the resource elements (REs) in the depicted RB are labeled with a corresponding antenna port group / antenna index, which simply represent logical grouping of antennas. However, it is understood that a device may be used in a device.

CSI-RS is a signal transmitted by an eNB to enable UE to transmit a channel to the eNB. CSI-RS is intended to be used in LTE-Ato, used for feedback to support SU-MIMO, MU-MIMO and CoMP. Since LTE Release 8 UEs (legacy UEs) are not aware of the CSI-RS, which makes it challenging to introduce the CSI-RS. The CSI-RS is planned to be in the PDSCH region. CSI-RS can be placed.

[0022] In some designs, CSI-RS may be used as a reference signal (CRS). In addition, in some designs, the whole symbol is which CRS REs are assigned to be CIS-RS. Such an avoidance of CRS symbols by CSI-RS may be helpful to minimize interference from CRS transmissions into CSI-RS transmissions. For example, if the CRS is a CSI, the CRS can be reduced by CSI. -RS unreliable in a given cell. In some designs, two-transmit antennas (2Tx) CSI-RS assignments may also avoid CRS symbols for all four-transmit antenna (4Tx) REs because cells could be using 4Tx antennas.

Also, in some designs, CSI-RS may be the first three symbols of the control signals ("control symbols"). Avoiding control symbols may also be useful in relay operation because of a relay node may need to be transmitted and received. In relay designs where relay advertises its backhaul DL subframes as MBSFN to its UEs 120, the relay may not be able to listen to the first few (one to three) OFDM symbols.

In some transmission modes, U-specific reference signals (UE-RS), also called Demodulation reference signal (DM-RS) may be transmitted by eNB 110 to the UE 120 estimate the channel for data Demodulation. In some designs, CSI-RS pattern may not depend on whether UE-RS based transmissions are scheduled or not. Therefore, in some designs, the REs allocated to CSI-RS may be selected to avoid UE-RS. As used by, this is the allocation of CSI-RS transmissions. Further explanations are given below. In some designs, CSI-RS are assigned transmission resources by the CRS and UE-RS. REFERENCE REFERENCES REFERENCE TO A FILM REFERRED TO IN A REFERENCE TO A CONTENT OF REFERENCE TO A DETAILED DESCRIPTION OF THE INVENTION. In some designs, additionally, CSI-RS may avoid collocation with synchronization signals and PBCH and SIBs. In some designs, as explained in greater detail later, CSI-RS RE allocation may also avoid overlap with paging channel of legacy UEs 120.

[0025] FIG. 3 is a block diagram representation of a wireless communication system. The horizontal axis 302 represents time (or symbol index) and the vertical axis 304 represents frequency. Each square tile represents a resource element (RE) representing a quantum of time-frequency transmission resource. The REs marked "C" (e.g., RE 306) may represent REs allocated to CRS transmissions. The RES marked "U" (e.g., RE 308) may represent REs allocated to UE-RS transmissions. The REs numbered from 1 to 60 (e.g., REs 310) may correspond to REs available for CSI-RS transmissions. In a given cell, the eNB 110 may be a subset of the REs and allocate the REs in the cell. The remaining REs may be used for data transmissions, as further described below.

In some designs, CSI-RS transmissions may be used as a common pilot for several UEs. the subframes where CSI-RS is present. In multiple antenna systems, CSI-RS may be transmitted by an antenna. Various designs, CSI-RS transmissions of different antenna ports may be multiplexed in a domain. For example, in a combined time / frequency domain multiplexing design, REs assigned to CSI-RS transmissions from different antenna patterns. However, in some designs, all CSI-RS transmissions (for all antennas) -RS transmissions during the used subframe. Such a selective CSI-RS transmissions (eg, UE 120 may not be required to receive multiple subframes of CSI-RS transmissions).

[0027] The eNB 110 may desire cells for the UE 120 to measure channels of adjacent cells. In such designs, the CSI-RS transmissions of some cells may be orthogonalized (e.g., use different set of REs). For example, in some designs, an eNB 110 may "blank" out REs (eg, transmissions or muting) assigned to CSI-RS transmissions in a neighboring cell. The specific RE pattern of different cells may be co-ordinated by eNBs 110 with each other.

In some designs, CSI-RS REs assigned to a particular transmit antenna port may be the same as that of the transmitter to the transmit antenna. Due to time variations in the channel characteristics, it is also possible to use the same OFDM symbol. For example, in some designs, REs marked 1.7, 19, 23, 25, 31, 55 and 59 in FIG. 3 may be used for 8 different antenna ports.

The CSI-RS is transmitted, allowing full power utilization. For example, because the CSI-RS may be transmitted at a time only from a single antenna port, the port may not be usable. Flowever, if multiple CSI-RS antenna port REs are allocated on one OFDM symbol, the CSI-RS is an active antenna port (ie, antenna port transmitting the signal) for an actual signal transmission.

The legacy UE 120 (such as a Rel-8 UE 120 in a Rel-10 network) may not be aware of the CSI-RS transmissions. 2 CRS ports are configured and 4 CRS aerial ports are configured. In some designs, the SFBC and the SFBC frequency shift time diversity (FSTD) schemes may be transmitting 2 data symbols on the basis of the Alamouti scheme. To minimize the impact of CSI-RS puncturing on the UEs, it is considered to be the least likely to be affected. As further explained below, instead of puncturing 2 REs in two different RE pairs, both REs in one pair may be punctured instead.

In some designs, SFBC-FSTD may use SFBC using antenna port 0, 2 on first 2 data REs and antenna ports 1.3 on the next 2 data REs. The term "data RE" is used to refer to data transmission. Flowever, as a reference for transmission of all signals, or may not be used for transmission at all. In some designs, the two REs employed in SFBC may be selected to be close to each other. In some designs, Rel-10 UEs 120 scheduling or employing a CSI-RS REs and the CRS REs. The mapping may be done in groups of 4 REs in frequency for SFBC-FSTD (2 REs in freq for SFBC). 2 REs. This may introduce power imbalance. CSI-RS is a multiple of 4 for 4-CRS (and 2 for 2-CRS) when scheduled using this mode.

When the number of available data is available (or RB or alternately per data allocation) is the form 4n + 2 for SFBC-FSTD (or2n + 1 for SFBC) SFBC / SFBC-FSTD may be two be used in combination with STBC where Alamouti scheme is applied in time. REs while keeping the power balanced.

[0033] FIG. 4A is a block diagram representation 400 of two sub-blocks, depicting REs assigned to CSI-RS, in some designs. The number of antenna ports and a number (1 to 8) representing an antenna port index are labeled using a combination of an alphabet (a, b, c, d, orf). Orthogonal multiplexing of 6 An eNB 110 with eight transmit antenna ports (8Tx) may select one of the groups. different eNBs 110 with 8Tx antennas each (one eNB 110 using one of the six groups a) to T).

Note that is OFDM symbols containing user equipment reference signal, or UE-RS, (e.g., symbols 450, 452), 6 REs (instead of 8) may be available for CSI-RS transmissions. CSI-RS antenna ports, antenna ports 1 to 4 may be placed on a OFDM symbol pair (eg, 450, 452) containing UE-RS, and antenna ports 5 to 8 may be allocated REs on the next adjacent OFDM symbol (eg, symbol 452). RB, such that all ports are covered by the RB. Neighboring symbols may be chosen for the purpose of allocation of CSI-RS resources.

In some designs, 4Tx eNBs 110 may choose the CSI-RS port {1,2,3,4} or {5,6,7,8} of one antenna group "a" to "f." In some designs, 2Tx eNBs 110 may choose RE will {1,2}, {3,4}, {5,6}, {7,8} in one group, for CSI-RS transmission. Therefore, antenna port assignment may be a CSI-RS REs of a particular antenna port. ENBs 110 with different antenna configurations.

Referring now to FIG. 4C, the resource block 480 shows a CSI-RS port for 4Tx eNBs 110. In some designs, the depicted pattern of FIG. 4C may be for every RB in which CSI-RS is assigned. It can be seen that the 4Tx assignment is fitted within 8Tx assignment by splitting the 8Tx assignments depicted in FIG. 4B into two groups for 4Tx. The 4Tx assignments may be further split into RE assignments for 2Tx eNBs 110.

It will be appreciated that the depicted RE assignment of FIG. 4C, the CSI-RS REs have been used as a reference, and the location of the CSI-RS is as follows. symbols 482, 484, two REs in different SFBC pairs would have been punctured.

Typically, the number of CSI-RS ports is higher than or equal to the number of CRS ports. It can also be appreciated that the number of CRS is 4, the CSI-RS port assignment could be for 4 or 8 antenna ports, 0, 4, or 8 In one aspect, such as orphan REs are left over ungrouped (ie, orphan REs). The number of CSI-RS antenna ports could be (2,4,8). In such a case, the CSI-RS REs are any or may be either 0, 2, 4, or 8 that is not used by SFBC. Aerial port 3 and 4 are swapped with antenna ports 5, 6 the property that no orphan REs are left may not be met. Note that some CSI-RS data can be used for CSI-RS.

Referring to FIG. 4C, block diagram representation of a resource block 480 is depicted, showing another exemplary assignment of REs to CSI-RS transmissions. In one aspect, the RE assignment in RB 480 differs from RB 450 in the RB 450 and is assigned to CSI-RS in RB 480 depicted in FIG. 4B. The problem when these REs is 482, 484 are used for CSI-RS and more on the below.

In some designs, when 2 REs are available for 4-CRS, using SFBC over 2 beams that is UE 120 is aware may be advantageously used to utilize full power instead for SFBC-FSTD. In some designs, when <4 REs are available for 4-CRS, or 1 RE for 2 CRS one modulation symbol beams that UE 120 can estimate using CRS may be transmitted. In some designs, the additional REs 482, 484 may simply be skipped. Note that, in the case of the SFs, grouping may be allowed. Whether to use the REs for CSI-RS or to protect the SFBC instead of the network (eg, by the eNB 110).

The UE 120 may be provided with information about the cells of the UE 120. To enable this, CSI -RS antenna patterns could be functions of one or more of the subframe index, radio frame index, single frequency network (SFN) number and cell ID. Based on the information, the UE 120 may be able to locate the CSI RS transmissions from a eNB 110.

CSI-RS signaling from an antenna is changing the CSI-RS signal from an antenna.

Some designs, the antenna port grouping of the CSI-RS may be orthogonal with each other, such as a port of interest (eg, 8,4,2 or 1) may be orthogonal to each other ( eg, due to time-frequency separation). In addition, a group with a smaller number of antennas may form a sub-group of a larger number of antennas. For example, CSI-RS patterns for 4 antenna groups (4Tx), which in turn may be 2 CSI-RS allocations for 2-Tx port CSI-RS. Therefore, in some designs, the use of the antisense transducer (eg, 8,4 or 2), number of transmit antennas such as a first number (eg, 8 or 4) of transmitter antennas is a superset of a second number of transmitter antennas (eg, 4 or 2) when the first number is greater than the second number.

In some designs, CSI-RS REs may be selected to be located at RE locations. CSI-RS REs are allocated. In some designs, the data is in the ungrouped REs (i.e., all data REs get allocated to CSI-RS transmissions).

SFBC-FSTD is a set of OFDMs for the SFBC-FSTD. symbols. This is a data encoding method that can help you minimize the number of orphan REs. In different designs, available REs may be computed on RB basis or for the entire data allocation.

As described further below, the CSI-RS transmission can cover different parts of the channel bandwidth on different subframes. The bandwidth and CSI-RS RE allocation patterns may be used as the secondary signaling signal (SIBs). ). UEs 120, may be transmitted by the UEs 120, while these signals may be transmitted, directed to the legacy UEs 120; CSI-RS aware UEs 120, in other RBs selected by the eNB 110.

In some designs, CSI-RS antenna port space may be partitioned between eNBs 110 of different power classes (more generally, two eNBs). For example, in some designs of CSI-RS REs, pico-cells could get multiple sets of CSI-RS REs. In general, the dominant interferer may be configured to the CSI-RS space of the weaker eNB. The assignment based on power class may be static, semi-static, or dynamic. CSI-RS power boosting \ tCSI-RS power boosting \ t .

The code division multiplexing (CDM) may be used as the CSI-RS symbols. In one aspect, the issue of power utilization. For example, instead of sending an antenna port 1.5, there are two adjacent OFDM symbols, they can be code division multiplexed (CDM). In some designs, CDM may be used for higher rank (e.g., rank 8) DM-RS pattern FDM may be used for lower ranks (e.g., ranks 4 and 2).

Referring now to FIGS. 6 to 13, some example of RE assignments to CSI-RS signals, used in LTE Rel-10, are depicted. In FIG. 6 to 13, the REs marked with "C" may be represented by CRS and the REs marked "U" may represent REs assigned to UE-RS.

In general, when certain data are assigned to a CSI-RS, such as UEs 120 (eg, Rel-8 UEs) 120) may not be aware of CSI-RS while release 10 UEs may be aware of the CSI-RS. UEs and legacy UEs 120 may be "rate matched" or "punctured" for compatibility.

In some designs, puncturing may have been achieved by CSI-RS. The legacy receiver may be able to receive and recovert transmissions using, e.g., error coding techniques. In some designs, rate matching may be based on the CSI-RS, but may not be the same as the CSI-RS. For UEs aware of the CSI, either the UEs and the eNBs are used. Rate matching is expected to be better than puncturing. In some designs, data are available for data transmissions by first ordering in frequency, followed by time.

Referring to FIG. CSI-RS transmissions in a group of four contiguous REs of a symbol are shown. It is understood that other groups of RE groups also. In the group 1400, a pair of REs 1404 may be assigned to CSI-RS, leaving the pair of REs 1402 available for data transmission. In the next pair of REs and the second RE in the RE pair 1403 may be a second pair of REs. 1401 results in puncturing of the two data RE pairs by CSI-RS transmissions. By contrast, only one data RE pair is punctured in the group 1400, using a group coding scheme (e.g., SFBC).

However, the use of the remaining data is available in the CSI-RS transmissions. REs may need to be carefully planned for SFBC or SFBC-FSTD groups. For example, SFBC and SFBC-FSTD require RE allocation in groups of 2 and 4 REs respectively. CSI-RS and CRS ports that lead to such cases are listed.

Referring to Table 1, CRS ports assumed for a particular CSI-RS assignment scenario. Thesecond column "Transmit Diversity Scheme" used for data transmissions. CSI-RS antenna port assignments. The fourth column is the one which is used in certain designs. The fifth column lists any possible rate matching issues on a RB basis.

Table 1

Referring to FIG. 15, for symbols 1500,1502,1504,1506,1512,1513,1514 and 1515 containing CSI-RS there are 11 available REs. These symbols may, e.g., correspond to the symbol indices 5, 6, 9 10, 12 or 13, as depicted in FIG. 3 to 13. The CSI-RS assignment patterns depicted in FIG. 15 highlight, among other aspects, CSI-RS with antenna port switching across CSI-RS symbols and across RBs. REs 1502 (marked with "") REs 1502 (marked with) F "and" f ") in the neighboring symbols, only one modulation symbol may be transmitted and only one CRS antenna port. As depicted, there are 2 symbols 1500, 1504 containing CSI-RS that have the orphan RE. The CRS antenna port used within an RB is the two OFDM symbols containing CSI-RS may be different. The antenna port used for the orphan REs is OFDM symbol containing CSI-RS may switch across RBs (marked as "AP 0" and "AP 1" in FIG. 15). In one aspect, both CRS antenna ports are used in the same way as the SFBC transmission.

[0064] The mapping scheme may be used. For the first CSI-RS symbols 1500, the antenna port is used on RBs (represented by symbol 1500) and antenna port 1 is used for odd RBs (symbol 1502). For second CSI-RS symbols, antenna port 0 is used as odd RBs (symbol 1506) and antenna port 1 is used on even RBs (symbol 1504). The CSI-RS REs in the RB are shown in FIG. 15th

As is depicted in FIG. CSI-RS assignments, there are 11 REs available for data transmissions. The first 10 REs may be used in 5 SFBC pairs for data transmissions. The remaining RE (orphan RE) may satisfy the following conditions: (1) on the orphan RE only one modulation symbol may be transmitted and only one CRS antenna port; (2) there are 2 symbols containing CSI-RS that have the orphan RE; the CRS antenna port used within RB is the two OFDM symbols containing CSI-RS are different; and (3) the antenna port used for the orphan REs is the symbol containing CSI-RS switches across RBs (even and odd). CRS antennas are used in the same way as the SFBC transmission: [0066] It will be appreciated that the mapping scheme for symbols 1500, 1504,1512 and 1514 achieves the conditions revealed above. For 1502, antenna port 0 is used on even RBs and antenna port 1 is used for odd RBs. For second CSI-RS symbol 1504, antenna port 0 is used on RBs and antenna port 1 is used on even RBs.

RBsofthe mapping scheme for symbols 1500.1504, 1512, and 1514 may be used as CSI-RS symbols and across RBs.

Referring now to symbols 1501, 1503, 1513, and 1515, mapping schemes are illustrated for rate matching around CSI-RS with antenna port switching across CSI-RS symbols and across RBs. The mapping scheme may be based on the SFBC-FSTD transmit diversity scheme. For symbols that do not contain CSI-RS (not depicted in FIG. 15), Rel-8 mapping scheme may be used. For symbols containing CSI-RS, e.g., symbols 1501,1503,1513 and 1515, there are 10 available REs. The first 8 available REs may be used to accommodate 2 SFBC-FSTD pairs. For the remaining 2Rs (orphan REs), the following mapping conditions may be satisfied: (1) on the 2 orphan REs; (2) the CRS antenna ports used for the orphan REs within the RB are the two OFDM symbols containing CSI-RS are different. That is, if one uses antenna ports (0, 2) for the orphan REs on the first CSI-RS symbol, then one uses antenna ports (1, 3) for the orphan REs on the second CSI-RS symbol; (3) the antenna ports used for the orphan REs switch across RBs. This is that all CRS antenna ports are used when the RBs are used for the SFBC transmission. Example mappings consistent with the above conditions are depicted for symbols 1501, 1503, 1513and 1515.

In some embodiments, the data are transmitted in a given cell during data transmissions in a given cell. In one aspect, the CSI-RS channel estimation of the neighboring cells, e.g., for the CoMP and HetNet scenarios. In some design, UEs 120, muting may simply mean that the eNB 110 is the most important source of information (eg, unused for any transmissions) by the eNB 110.

However, UE 120, which has no knowledge of muting and therefore attempts to reduce the receiver performance. Therefore, in one aspect, the UE 120 can be used as a reference to the UE 120 to maintain receiver performance. In some designs, UEs 120 may be rate matched around the mouth REs.

[0070] FIG. 16 is a block diagram representation of a group of two symbols 1600 from an RB in which CSI-RS is transmitted. The REs include SFBC pairs 1602,1608 and 1612 allocated for data transmissions. REs 1604 are assigned to CSI-RS transmissions in the bearer cell. REs 1606 are assigned to CSI-RS transmissions in a bearer cell. Similarly, REs 1610 are also muted in the bearer cell. It can be seen that the SFBC 1602 and 1608 time-frequency contiguous REs, the SFBC group 1612 is split in two parts due to the intermediate CSI-RS pattern 1604 and mutes REs 1606. Using the rate matching technique described before to rate Counter-Strike Codes and CSI-RS tones

In some designs, as depicted in the symbols 1601 in Fig. REs may also occur for 2 CRS ports, even if the number is available in the group 1601 (as shown in the group 1601). ). The scheme is described above. That is, if there is one or more orphan REs, only one modulation symbol is transmitted on orphan RE using only one antenna port. In some designs, the orphan REs may also be unused (i.e., transmissions performed). The antenna port used changes across RBs. A further optimization of the antenna ports changes for the same OFDM symbol within an RB can also be considered. However, the mapping complexity is increased and is the exact combination of CRS, CSI-RS, and mutes REs. SFBC can be switched over RBs.

Referring to FIG. 17, illustrated is an example of a mapping scheme 1700 for rate matching around CSI-RS and mutes REs using space-time block coding (STBC) transmit diversity scheme. It is noted that CSI-RS for the sake of simplicity and clarity. The mapping scheme 1700 is the same for even and odd RBs. CRS antenna ports on the symbols containing CSI-RS / moles REs. It is noted that other symbols may be used.

With reference to FIG. 18 and FIG. CRS aerial ports can be used as CSI-RS or muted tones may be used. The alternate scheme, SFBC and SFBC-FSTD may be used for other symbols that do not have any muting or CSI-RS RE assignments. For STBC-FSTD, antenna ports may be alternate between (0.2) and (1.3) on the available REs. In some designs, for CRS antenna ports, the antenna ports used for STBC may be fixed at the first available RE of odd RBs to (1.3). In one aspect, the fixed mapping may help to ensure equal utilization of all antenna ports.

For example, in FIG. 18, a symbol pair 1800 (e.g., symbols 5 and 6 of RB is which CSI-RS are assigned) is shown for an even RB. STBC-FSTD pairs, CSI-RS and muted, as described above, the remaining RE (marked "D1") in each symbol form is RE pair 1802, which may be assigned to antenna ports (0 , 2). Similarly, the RE pair 1902 in the symbol pair 1900 may be assigned to antenna ports (1.3).

CSP-RS and SFBC-FSTD. CSI-RS and 2 CRS and (b) 4 CSI-RS and 2 CRS, as previously discussed. In some designs, single antenna port transmissions may be used in the orphan REs for 2 CRS case. In some designs, SFBC transmissions may be used in the orphan REs for the 4 CRS case. The antenna ports may be switched across the RBs and across the OFDM symbols.

Referring again to FIG. 16, 16, and 1601 are shown. It may be seen from FIG. 16 that the REs assigned to the SFBC pair "B" 1612 are three subcarriers apart. In some designs, the UE 120 may be a RE group (e.g., both REs in an RE pair). Relevant UEs 120, as typical REs assigned to a UEs 120, such as REs or one RE away within a symbol and by other UEs 120 to simplify Implementation. Therefore, in certain designs, a pair of REEs can be used in a RE pair. The term "separated RE pair" is used to refer to REs. For example, the two "B" REs in Fig. 16 have a separate RE pair. [0077] Certain designs may be overcome in a single aspect, by means of a pair of REs. For example, in a design, eg, as described in this article. Pseudo-code listed in Table 2. It will be noted that the pseudo-code is listed in the RB of 12 REs. As noted further below, a similar assignment can be made for a single RBs (i.e. multiple 12 RE groups assigned to a single UE).

Table 2

[1] In addition to a single subcarrier, within the scope of a single subcarrier.

Referring now to Fig. 20, example RE assignment 2000, when multiple consecutive RBs are used for transmissions to a given UE 120, is depicted. It will be appreciated by one of the best in the field (eg, N <24, when two RBs are used for a given UE 120) . Furthermore, as can be seen from FIG. RBs may result in a reduced number of ungrouped (or orphan) REs. For example, while REs marked "E" and "e" in the symbol pair 1601 were ungrouped, the corresponding REs in FIG. 20 are paired and assigned in the RE assignment 2000;

A similar RE assignment technique may be used for CRS ports which uses SFBC-FSTD. SFBC pair may also be skipped. Alternately, if the number of SFBC pairs found is an OFDM symbol is odd, the last SFBC pair may be skipped. CRS ports are used equally.

Alternatively, a pair of RBs (eg, "E" and "e" in symbol pair 1601 may be left ungrouped even when it is possible to pair them up) REs from another resource block).

In some designs, the CSI-RS may be allocated in subframes that include PBCH and Sync signals. For example, this is the result of a transmission frame structure 0, 4, 5 and 9 in a transmission frame structure.

In designs where CSI-RS is omitted on such subframes, REs may still be allocated so that the relay access and backhaul partitioning may be performed, eg, subframes 0, 4, 5 and 9.

When time domain duplexing (TDD) is used as a wireless channel, in some designs, PBCH may be a subframe index. not. In some designs, sub synchronization (SSS) may be transmitted on the last OFDM Symbol in subframe 0 and 5. In some designs, these symbols may be excluded from CSI-RS transmissions. CSI-RS REs may be available on subframes 5 with just SSS. SIB1 and CSI-RS allocation may avoid such subframes also.

Table 3 summarizes a different uplink-downlink configuration mode (column 1) with allocation of each subframe for the given configuration to uplink transmissions ("U"), downlink transmissions (" D ") and synchronization signals (" S ").

Table 3

In FDD, select paging to be on subframes: {9} or {4, 9} or {0, 4, 5, 9 }, re periodically. In TDD, performing paging is subframes {0}, {0, 5}, {0, 1, 5, 6}, periodically. In Config 0, only 3 DL OFDM symbols on special subframes may be available, and therefore CSI-RS may not be performed on these symbols.

In some designs, therefore, the bandwidth covered by CSI-RS transmission may be split into multiple groups (e.g., two groups). For example, on Subframe 0, 50% of the bandwidth may be covered by CSI-RS transmission and 50% bandwidth may be covered by CSI-RS transmissions. In some designs, data transmissions are UEs 120 that are aware of CSI-RS transmissions, may be performed outside of these subframes. In some designs, CSI-RS may not be supported for Config 0.

CSI-RS transmissions may be allocated to REs in multiple sub-frames. In one aspect, the allocation of CSI-RS REs across multiple subframes may be provided. In one aspect, using multiple subframes may enable subframe partitioning in HetNet configurations.

The allocation of CSI-RS across multiple subframes may also help with the use of CSI-RS in relay operations. For example, a relay node may transmit CSI-RS is a DL-back from mac on DL backhaul. By utilizing multiple subframes, a relay node may not have the same subframe as the relay design.

In various designs, the sub-subprames may not be split into subframes with the periodicity of a frame (e.g., 10ms). For flexibility, RE patterns for CSI-RS may be used as a bitmaps. The use of bitmaps may also allow for future compatibility with other RE allocations. For example, in some designs, unequally spaced (or aperiodic) subframes may be assigned to a subframe period. As a non-limiting example, sub-frames 0, 5 and 20 may be allocated in a given sequence of 40 millisecond periods, with the pattern being re every 40 milliseconds. Correspondingly, the aperiodic subframe pattern may be conveyed to UEs 120 using a downlink and UEs 120 may be configured to receive the aperiodic (or unevenly spaced) transmission pattern, which has a period of repetition.

In some designs, the REs allocated to CSI-RS transmissions, e.g., to the particular antenna port, may be hopped over a period of time. In one aspect, hopping may enable UEs 120 to receive at least a few CSIs. In some designs, a different hopping pattern may be used for each antenna port. Alternatively, in the field of antenna ports (i.e., transmissions for all types of aerial ports). The alternative may work better if a CSI-RS collide and does not use the CQI in that case. CQI / PMI to be erroneous more often.

[0092] In some designs, muting pattern may be selected based on a power class of the bearer network. For example, in some designs, a CN-RS locations of all pizzas. In some designs, an eNB 110 for the femto cell mute the CSI-RS location of all macros and pizzas. In some designs, the UE 120.

CSI-RS transmissions in other cells CSI-RS transmissions in other cells. The available REs may include, for example, REs assigned to SFBC pairs or SFBC-FSTD pairs as depicted in FIG. 15.

For example, as depicted in FIGs. 15 to 20, the REs not assigned to the CSI-RS and / or the group of the symbols. In some designs, REs from two symbols away may also be grouped also (e.g., symbols 5, 6, 9 and 10 in an CSI-RS are assigned). In some designs, REs are one or two subcarrier indices away may be grouped in a single data transmission group (e.g., RE pair 1516 in FIG. 15).

Some designs, some REs may be left over after CSI-RS and data transmissions (e.g., the RE marked "F" in symbol 1500). In some designs, the data transmission to another UE 120. In some designs, the remaining REs may be left unused (i.e., transmissions performed).
