Message) may be not suitable in downlink CoMP environment to two or more CSI-RS of user device transmissions and
IMR configuration information.
Up to the present, the transmission method of CSI-RS configuration information is described.Hereinafter, it will be described in further detail and be used for
The IMR configuration information of ZP-CSI-RS configuration method and the transmission method of IMR configuration information.
Fig. 4 be show be used for transmission according at least one embodiment in transfer point " interferometry resource (IMR's) matches
The flow chart of the method for confidence breath " (" IMR configuration information ").
Referring to Fig. 4, in the transmission method (400) of IMR configuration information, at step S410, transfer point can be determined (i.e.
Configuration) downlink interference measurement of the IMR configuration information for special user equipment (UE), allow to hold in CoMP environment
Row CSI measurement.At step S420, interferometry resource (IMR) index is can be used to identify each IMR with confidence in transfer point
Breath, and to user device transmissions IMR configuration information.Matched more specifically, IMR index can be used in service transmission point to identify
The multiple IMR set.In addition, it is excellent to notify that IMR index can be used in service transmission point when to user equipment requests CSI feedback
The IMR configuration information of choosing.Here, IMR configuration information may include resource allocation information and subframe configuration information.
As the case where ZP-CSI-RS, four resource units in a PRB pair can be used to configure an IMR.Picture
The case where ZP-CSI-RS, transfer point can be come by using resource allocation information and subframe configuration information to user device transmissions
IMR configuration information.
Meanwhile in the operation (S420) to user device transmissions IMR configuration information, CSI-RS configuration information can be connected
It is transmitted together with IMR configuration information.
In CoMP environment, IMR configuration information can be transmitted for CSI measurement.Hereinafter, it will be described in further detail
Embodiment associated with the transmission method of IMR configuration information.Here, IMR configuration information transmission method may include that (i) is used
IMR index identifies IMR configuration information, and (ii) is to user device transmissions IMR configuration information, and (iii) is asked to user equipment
Seek CSI feedback.
Embodiment 1：" CSI-RS-Config " message is used again
CSI-RS configuration information and IMR configuration information can be used for measuring the signal power of transfer point.It can be by CSI-RS
Configuration information and IMR configuration information are transferred to relative user equipment (such as UE1 (120) from service transmission point (such as eNB 110)
Or UE2 (122)).Here, service transmission point can indicate the transfer point to relative user equipment transmitted downlink signal.
Therefore, service transmission point (such as eNB 110) can be by using " CSI-RS-Config " message shown in Figure 2 to correspondence
User equipment (such as UE1 (120) or UE2 (122)) transmission CSI-RS configuration information and IMR configuration information.Here, CSI-
RS configuration information can be configuration information associated with the CSI-RS transmitted by all transfer points in CoMP measuring assembly.
IMR configuration information can be configuration information associated with IMR required for each transmission point.
User equipment (such as UE1 (120) or UE2 (122)) can receive CSI-RS configuration information.Here, CSI-RS
Configuration information can be configuration information associated with the CSI-RS transmitted by all transfer points in CoMP measuring assembly.Cause
This, in this case, service transmission point (such as eNB 110) is not needed by using " zeroTxPowerCSI-RS-
R10IE " clearly transmits the ZP-CSI-RS configuration information for resource unit silence.Typically, silent for resource unit
ZP-CSI-RS configuration information can be used for reduce may be in the downlink of the transfer point in CSI-RS and CoMP measuring assembly
The interference occurred between signal.
In embodiment 1, service transmission point (for example, eNB 110) can simultaneously to user equipment (such as UE1 (120) or
Person UE2 (122)) transmission CSI is configured and IMR configuration, to use " CSI-RS-Config " message again.Here, CSI configuration and IMR match
Setting can be configured with every transfer point.The configuration information for being used for transmission CSI-RS a little can be passed by " CSI-RS-r10IE "
It is defeated.Meanwhile IMR configuration information can be transmitted by " zeroTxPowerCSI-RS-r10IE ".In this case, when matching
It sets or when determining IMR configuration information, wherein the transmission signal of the transfer point of transmission CSI-RS is used as the interference hypothesis of interference
It may be not necessarily for IMR configuration.
For example, transmitting CSI-RS associated with transfer point A (110) by using " CSI-RS-r10IE " with confidence
It in the case where breath, is only used for " without IAInterference hypothesis " (do not include IAInterference hypothesis) IMR configuration information can be used
" zeroTxPowerCSI-RS-r10IE " is transmitted.Here, without IAInterference hypothesis can with interfered described in table 4 it is false
If exclusion " including I in the middleAInterference hypothesis (for example, IA+IB+IO+ N, IA+IC+IO+ N and IA+IO+ N) " residual interference it is false
If corresponding.
As set forth above, it is possible to determine that (or difference) necessary interference is false for each transfer point of transmission CSI-RS
And if IMR can be configured according to (distinguishing) interference hypothesis determined.In this case, user equipment (example
Such as, UE1 (120) or UE2 (122)) it can be in the case where the instruction of no service transmission point (such as eNB 110) according to every
Each interference hypothesis that a transfer point needs calculates SINR value in advance.That is, SINR value can be with the every necessary dry of each transmission point
Hypothesis is disturbed to calculate in advance.
It can be based on by " zeroTxPowerCSI-RS-r10IE " come the IMR configured simultaneously
" 16 bitmaps (" BIT STRING (SIZE (16)) ") " of " zeroTxPowerResourceConfigList-r10 " field
To identify.In the case that at least one certain bits in bitmap are set as " 1 ", indicate corresponding ZP-CSI-RS resource and be used as
IMR.For example, in the case where IMR is used as shown in Figure 5, " zeroTxPowerResourceConfigList-r10 " field
Bitmap can be " 1000001010010000 ".In this case, when ZP-CSI-RS index associated with IMR configuration
Be assumed to be 0,6,8 and 11 it is as shown in Figure 5 when, ZP-CSI-RS index 0,6,8 and 11 can be 0,1,2 and 3 pair with IMR index
It answers.
In addition, user equipment (for example, UE1 (120) or UE2 (122)) can only arrange being set as in bitmap " 1 "
Part, as shown in figure 5, and being indexed according to bitmap sequence by execution IMR to identify or distinguish each IMR.Service passes
Defeated point (such as eNB 110) can by using according to the above-mentioned IMR index that scheme determines of indexing come to user equipment (example
Such as, UE1 (120) or UE2 (122)) request CSI feedback associated with preferred interference hypothesis.
Embodiment 2：In the case where individual transmission is used for the configuration information of each IMR
Referring to Fig.1 and Fig. 4, as described above, transmitting downlink chain to user equipment (such as UE1 (120) or UE2 (122))
The service transmission point (such as eNB 110) of road signal can be passed to relative user equipment (such as UE1 (120) or UE2 (122))
Defeated CSI-RS configuration information and IMR configuration information.Here, CSI-RS configuration information and IMR configuration information can be transmitted, with
In the signal power of measurement transfer point.In such a case, it is possible to which every IMR independently transmits IMR configuration information.For example, such as Fig. 6
Shown, in the case where the IMR of N (integer that N is 0≤N≤16) a quantity, configuration information can be by using N number of quantity
The independent son of independent resource configuration information (" zeroTxPowerResourceConfigList-r1x " in Fig. 6) and N number of quantity
Frame configuration information (" zeroTxPowerSubframeConfig-r1x " in Fig. 6) transmits.Here, resource allocation information and
Subframe configuration information can carry out separate configurations with every IMR.In other words, one or more IMR configuration information can be directed to user
