Abstract

The invention provides a configuration method of an antenna port. The method comprises the following steps that: when user equipment (UE) accesses a network, a network side determines antenna port resources used by the UE according to rules of configuring different antenna ports by different UE, and the network side informs the UE of configured antenna port resources by using control signaling. By the method provided by the invention, the interference problem among the UE during data receiving is effectively removed.

Description

A kind of collocation method of antenna port
Technical field
The present invention relates to the resource distribution technology in the mobile communication system, particularly relate to the antenna port collocation method in multi-user-mimo systems.
Background technology
In existing long-term evolution enhancement system (LTE-A), subscriber equipment (UE) is not distinguished mutually by antenna port, but shared all antenna ports.Like this, the interference problem in the time of can having Data Receiving between UE.For example, for certain user equipment (UE) 1, the data Y that the pilot frequency locations on its antenna port Port1 receives can be represented by formula (1):
Y=H 1W 1S 1+ H 1W 2S 1+ N formula (1)
Wherein, H 1Be the channel response of UE1 experience, W 1, W 2Be respectively the pre-coding matrix that UE1 and UE2 adopt, UE1 and UE2 are the user on the current antenna port Port1, S 1Be the data that pilot frequency locations sends, N is a white Gaussian noise.
As can be seen, the interfere information that has comprised UE2 in the received data of UE1 is H from formula (1) 1W 2S 1Like this,, must eliminate the interference of UE2, at this moment, only guarantee H UE1 in order to try to achieve the precise channels estimated value 1With W 2Quadrature, i.e. H 1W 2=0, make Y=H 1W 1S 1+ N could eliminate the interference between different UEs on the same port.
Because the pilot tone in the existing system between each UE is not carried out orthogonalization, is difficult to reach H 1W 2=0.Therefore, there is interference problem between UE in the existing system inevitably.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of collocation method of antenna port, the interference problem when this method can effectively be eliminated Data Receiving between UE.
In order to achieve the above object, the technical scheme of the present invention's proposition is:
A kind of collocation method of antenna port, this method may further comprise the steps:
When the user equipment (UE) access network, network side is determined the antenna port resource that described UE uses according to the principle of different UEs configuration different antennae port, and utilizes the control signaling to give described UE with the antenna port resource notification that is disposed.
In sum, in the collocation method of the antenna port that the present invention proposes, behind the UE connecting system, be the different antenna port of different UEs configuration, so, the interference problem in the time of can avoiding Data Receiving between UE.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with specific embodiment.
Core concept of the present invention is: for the different different ports of UE definition, distinguish different users by port, eliminate the interference between the different user.
Based on above-mentioned thought, for a certain UE1, the data Y that the pilot frequency locations on its antenna port Port1 receives can be represented by formula (2):
Y=H 1W 1S 1+ N formula (2)
From formula (2) as can be seen,, therefore, no longer there is the interfere information of other UE in the received data of UE1 because antenna port only used by UE1, thus other users' interference can effectively reduce the pilot data reception time.
The embodiment of the invention one mainly comprises:
When the user equipment (UE) access network, network side is described UE configuration antenna port resource according to the principle of different UEs configuration different antennae port, and utilizes the control signaling to give described UE with the antenna port resource notification that is disposed.
Here, as previously mentioned, be UE configuration antenna port resource by principle according to different UEs configuration different antennae port, other users' interference in the time of can effectively avoiding Data Receiving.
The Notification Method of the antenna port resource that is disposed particularly, can for:
Network side is determined the antenna port offset parameter of the both port of origination correspondence of described antenna port resource according to default antenna port offset parameter-both port of origination mapping table, and sends the control signaling of carrying described antenna port offset parameter to described UE;
Described UE determines described antenna port offset parameter according to the described control signaling that receives, and by inquiring about described antenna port offset parameter-both port of origination mapping table of self preserving, knows the antenna port resource of described antenna port offset parameter correspondence.
In the said method, described antenna port offset parameter-both port of origination mapping table is to be arranged at network side and UE side in advance respectively.Like this, network side only needs the radio port offset parameter of the both port of origination correspondence of antenna port resource is notified to UE, and UE can inquire about described mapping table according to this offset parameter and obtain corresponding both port of origination numbering.According to the antenna port number of plies of this both port of origination numbering and UE use, can determine and be its antenna distributed port resource.Obviously, carry the Notification Method of radio port offset parameter in the above-mentioned control signaling, can effectively reduce the expense of control signaling.
Particularly, the UE side knows that the method for the antenna port resource of described antenna port offset parameter correspondence is:
Described antenna port offset parameter-both port of origination mapping table that the UE inquiry self is preserved, know the pairing both port of origination numbering of its antenna port offset parameter that receives M, antenna port number of plies N according to described M and UE use, the port numbering scope that can determine described antenna port resource for (M, M+N-1).
Preferably, the antenna port number of plies N that described UE uses can further be carried by described control signaling, so, can be the different user configured port number of plies (being the operable port number of UE), thereby can increase the flexibility of scheduling.
Antenna port with demodulated reference signal (DMRS) in the LTE-A system is configured to example below, further sets forth the Notification Method of above-mentioned antenna port resource:
Table 1 is a DMRS antenna port offset parameter-both port of origination mapping table, because the DMRS port numbers is 7-14 in the LTE-A system, therefore having represented to have provided the DMRS port numbers is the corresponding respectively antenna port offset parameter of 7-14, and this parameter is represented with 3 bits.For example, the antenna deviation parameter of receiving as certain UE is 100, and then the initial antenna port of this UE is 11, simultaneously, can obtain the number of plies of employing at this moment by control messages, if the number of plies that UE adopts is 2, then UE adopts antenna port 11,12 to carry out data demodulates.If the antenna deviation parameter received of UE is 001, and the number of plies of high-rise configuration is 3, and then UE comes demodulating data by antenna port 8,9,10, by that analogy.
Table 1
Here need to prove that the antenna port number of plies of UE use also can be a default value in actual applications, set in advance and be stored among the UE, like this, do not need to carry this number of plies information in the control signaling by system.
Preferably, for better with the existing system compatibility, the above-mentioned control signaling that is used to notify the antenna port resource that is disposed can be passed through Physical Downlink Control Channel (PDCCH) and send.
In sum, more than be preferred embodiment of the present invention only, be not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
