Further, the present disclosure relates to the UE itself, the UE may also or chip components therein. In addition, the base station involved in the present disclosure may be, for example, eNB (evolution Node Base Station, an evolved node base station) or the eNB chip components.
[0035]
TXRU (transceiver unit, the transceiver unit) is a radio transceiver unit has a separate phase and amplitude. Figures 1 and 2 illustrate two examples of the relationship between the antenna and TXRU. In FIGS. 1 and 2, q is a Tx signal vectors of the same polarization means at the M antennas within one of, w and W are broadband TXRU virtual weight vector and matrix, and x is M TXRU TXRU a TXRU at signal vector. Parameter M TXRU number indicating TXRU dimensional polarization directions of each antenna array of each column.
[0036]
In 2D array antenna, the number of antennas can be expressed as (M, N, P), where, M having the same polarization direction in each column the number of antennas, N is the number of columns of the antenna array, and P is polarization antenna the dimension direction. Figure 3 shows a 2D cross-polarized antenna array. As shown in FIG. 3, the antenna array with M rows, N columns of antenna elements and a plurality of two-dimensional polarization directions. In the antenna unit shown in FIG. 3, the solid line indicates a polarization direction, and the dashed line indicates the other polarization direction.
[0037]
TXRU concept combines, the number of antennas (M, N, P) can be converted into TXRU number (M TXRU , N, P). Currently, in the field of wireless communication technology has been on the M TXRU consensus of values. Further, in the present technical field wireless communications for TXRU consensus also provided, as shown in Table 1.
[0038]
Table 1 Antenna arrangement
[0039]
[0040]
As can be seen from Table 1 above, the 3D MIMO (3-Dimension Multiple-Input Multiple-Output, MIMO-dimensional) system, there are various combinations of the antenna array. Meanwhile, the number of TXRU may also vary from 4 to 64, and the same number TXRU also correspond to different antenna configurations. Different antenna configurations will result in different channel characteristics of the physical channel, when the base station should use different codebooks reflect the physical channel characteristics. In addition, different antenna configurations will also affect the way the base station transmits a reference signal and UE measurement and feedback radio channel characteristics. Therefore, to improve the transmission efficiency, the base station notifies the terminal UE antenna configuration is essential. Accordingly, the present disclosure proposes a new base station to the UE antenna configuration designed to transmit a 2D and 3D MIMO array antenna system services.
[0041]
FIG 4 illustrates the structure of a wireless communication system according to the present embodiment of the disclosed embodiment of the electronic device 400. As shown, the electronic device 4004 may include a processing circuit 410. Incidentally, both the electronic device 400 may include a processing circuit 410 may also include a plurality of processing circuit 410. Further, the electronic device 400 may further include an antenna array 420 and a communication unit 430 and the like.
[0042]
Processing circuitry 410 may be configured to perform the following operations: based on the electronic device 400 corresponding to the antenna array 420 to determine the appropriate TXRU configuration. As mentioned above, each associated with a set of TXRU antenna elements having the same polarization direction, the antenna array with M rows, N columns of antenna elements and a plurality of P-dimensional polarization direction, where M, N and P is a natural number.
[0043]
Those skilled in the art will appreciate that the processing circuit 410 may include a variety of discrete functional units to perform various functions and / or operations. Incidentally, these functional units may be physical or logical entities, and the different names may be realized by means of the same physical entity.
[0044]
For example, the processing circuit 410 may include a determination unit (not shown), the determination unit 420 may be based on the antenna array configuration to determine the appropriate TXRU.
[0045]
Further, the processing circuit 410 may also be configured to perform the following operations: add antenna configuration information to the RRC (Radio Resource Control, RRC) signaling for a wireless communication system UE. Here, the antenna configuration information may be used to obtain the number of the antenna array 420 of TXRU. Accordingly, the processing circuit 410 may include adding units (not shown), the addition unit may add antenna configuration information to the RRC signaling.
[0046]
Use 400 may be configured via RRC signaling transmission antenna information electronic device according to embodiments of the disclosed embodiment, the antenna configuration information on the number of the antenna array may be used to obtain 420 TXRU. Because it is notified by RRC signaling, it is possible to save radio resources, and reduce the traditional notification UE unnecessary analytical support for UE TXRU transmission. Thus to achieve the effective transmission TXRU configuration information.
[0047]
FIG. 5 shows an example of the configuration TXRU antenna array. 5, the antenna array configuration (8,4,2,16), the antenna array has 8 rows, four antenna elements and a plurality of two-dimensional direction of polarization, and having 16 TXRU. It is noted that, due to the same direction of polarization in each dashed blocks belong to the same TXRU, and two-dimensional antenna array having a direction of polarization, each corresponding to the two dashed box TXRU. Similarly, in the antenna array configuration (8,4,2,32), the antenna array has 8 rows, four antenna elements and a plurality of two-dimensional direction of polarization, and having 32 TXRU. In the antenna array configuration (8,4,2,64), the antenna array has 8 rows, four antenna elements and a plurality of two-dimensional direction of polarization, and having 64 TXRU.
[0048]
As can be seen from FIG. 5, the antenna array in 2D, even if the configuration of the antenna array (M, N, P) the same, may also have a different number TXRU. Thus, TXRU efficient transmission configuration information is necessary.
[0049]
According to embodiments of the present disclosure preferred embodiment, the antenna may be used to obtain configuration information about at least the parameters M TXRU number information in the polarization direction of each dimension of each column indicates the antenna array 420 of the TXRU. In other words, the parameters M TXRU refers to the number TXRU polarization directions of each dimension of each column of the antenna array 420.
[0050]
FIG 6 shows another example of the antenna array configured TXRU. 6, the antenna array configuration (8,4,2,2), the antenna array has 8 rows, four antenna elements and a plurality of two-dimensional direction of polarization, and each column in each of the antenna array a two-dimensional direction of polarization having TXRU. It is noted that, due to the same direction of polarization in each dashed blocks belong to the same TXRU, and two-dimensional antenna array having a direction of polarization, each corresponding to the two dashed box TXRU. Similarly, in the antenna array configuration (8,4,2,4), the antenna array has 8 rows, and a plurality of four-dimensional direction of polarization of antenna elements 2, and each column electrode of each dimension of the antenna array direction having four TXRU. In the antenna array configuration (8,4,2,8), the antenna array has 8 rows, and a plurality of antenna elements 4 two-dimensional direction of polarization, and the polarization direction of each dimension of the antenna array of each column 8 having TXRU.
[0051]
Incidentally, the antenna array configuration parameter M TXRU indication, M, N and P may be arranged in a variety of order, provided that the order of sending and receiving sides can be unified in advance. Sequence parameter in the example of FIG. 6 as (M, N, P, M TXRU ), and in the subsequent description of the sequence parameter places (M TXRU , M, N, P) as an example.
[0052]
According to embodiments of the present disclosure preferred embodiment, the parameters M TXRU range may comprise at least 1,2,4 and 8 and the parameter M TXRU value is equal to or less than the value of M parameter. By Table 1, the antenna arrangement is possible to obtain the parameters M TXRU relationship between the parameter and the range of M.
[0053]
According to the present embodiment disclosed preferred embodiment, it may be included in the RRC signaling may be used on 3D MIMO (3-Dimension Multiple-Input Multiple-Output, 3 dimensional input multiple output) / FD MIMO (Full-Dimension Multiple-Input Multiple- the output, Victoria full input multiple output) systems antenna port number information to indicate the number of TXRU. Since the number of ports equal to the number when the antenna TXRU, so when the RRC signaling already contains information about the number of antenna ports, this information can be used for 3D MIMO / FD MIMO system to indicate the number of TXRU.
[0054]
According to embodiments of the present disclosure preferred embodiment, the antenna configuration information may be explicitly contains information about the antenna configuration parameters, and can implicitly contains information about the antenna configuration parameters. Next, on the first antenna configuration information explicitly contain the information about the antenna configuration parameters are described in detail.
[0055]
It is known to the inventors that the antenna notification information element (antennainfo information elements) as part of a radio resource control information is defined in the RRC information unit. Antenna and processes the notification information element structure is shown below.
[0056]
[0057]
[0058]
As can be seen, the notification information element in the above antennas, the UE is notified of the contents with a number of antennas (antenna port) port, a transmission mode (transmission mode) and the corresponding codebook subset constraint (codebook subset restriction). Since the antenna element is a radio resource notification control information (RRC) part of the information unit, the antenna notification information should be transmitted in the random access procedure to the UE in the UE. When the UE during the random access, the base station to the UE sends a RRC connection request in the random access channel signaling is to establish an RRC connection. The base station will then send forward access channel to the UE RRC to establish a signaling connection, the antenna element on the notification information contained therein. Further, codebook subset constraint information may also be transmitted in the CSI process unit (CSI-Process). In this case, the codebook subset constraints still in the CSI may be transmitted during the information unit. Meanwhile, in order to maintain the integrity of the information notification unit current antenna, it is desirable to add only some antenna communication information, and not to change the existing information unit.
[0059]
According to embodiments of the present disclosure preferred embodiment, the antenna configuration information includes the antenna configuration parameters may include a parameter M TXRU one or more parameters M, the parameter N, parameter P, and combinations thereof. More preferably, the antenna configuration parameters may include a parameter M TXRU , the parameters M, N parameter and the parameter P.
[0060]
Further, according to the disclosed preferred embodiment, the processing circuit 410 (e.g., processing circuit 410 includes the adding unit) antenna configuration information can be added to the RRC signaling notification information element antenna or a CSI-RS (channel state information reference signal , the channel state information reference signal) configuration information unit.
[0061]
Specifically, for example, may be added in units called antennaNumberCount in AntennaInfoDedicated-r13. This unit includes four parameters (M TXRU , M, N, P). In order to comply with Table 1 antenna configuration, M may be equal to 4 or 8, N may be equal to 1, 2 or 4, P may be equal to 1 or 2, and the corresponding M TXRU can be derived from Table 1. Since this is added a new portion of the content, so that it should appear after the contents of traditional antenna unit represented by the following notice information after the change.
[0062]
[0063]
When the base station notifies these parameters to the UE, it may be a predetermined number of bits to represent the function of the actual value or actual value of the antenna configuration parameters. For example, 1 or 2 bits may be used to indicate that these antenna parameters, or transmission of actual values of these antenna parameters. Further, due to the exponential power of 2 of these antenna parameters are, for example, the base station may be selected to log 2 (M TXRU transmission of these parameters in the form of, M, N, P) of.
[0064]
Meanwhile, the parameter sequence (M TXRU , M, N, P), the base station can use the parameter M / M TXRU instead of the parameter M TXRU or M. In this manner, if a system parameter M / M TXRU are fixed, then this parameter can be individually transmitted, thus reducing some overhead. Meanwhile, if the number of antennas in a TXRU is fixed, the UE can obtain the number by the total number TXRU antenna system, so that only two parameters need to be transmitted in the sequence of parameters (M, N, P) in.
[0065]
Another method is to obtain a number of new TXRU portion CSI-RS-Config-r13 called CSI-RS-Config information element is defined, which include the antennaPorts Count-r13. Since the number of ports equal to the number of the antenna TXRU, so that the number TXRU can be obtained from this new section. FIG CSI-RS-Config information element modified as follows.
[0066]
[0067]
Using antennaPortsCount-r13, the user can obtain the number TXRU. Thus, in this embodiment, the parameter sequence (M TXRU , M, N, P) can be simplified to (M, N, P), and the antenna parameters can be obtained after that number TXRU. Meanwhile, the parameter sequence (M, N, P) can be explicitly transmitted CSI-RS-Config-r13 in.
[0068]
Next, the antenna configuration information implicitly contains the information about the antenna configuration parameters are described in detail.
[0069]
According to embodiments of the present disclosure preferred embodiment, the processing circuit 410 (e.g., processing circuit 410 includes the adding unit) may utilize the RRC signaling codebook subset restriction to add antenna configuration information. More preferably, the processing circuit 410 (e.g., processing circuit 410 includes the adding unit) by the codebook subset constraint for adding a predetermined number of bits to express the antenna configuration information selection code present in the bit string. Instead, the processing circuit 410 (e.g., processing circuit 410 includes the adding unit) may be added by a codebook index in the codebook subset constraints expressed antenna configuration information.
[0070]
In particular, the present disclosure proposes a new transmission mode, and using codebook subset constraint to distinguish different antenna configurations. First propose a new transmission mode for a vertical beamforming / FD MIMO system. This new transmission mode defines a set of constraints comprises a codebook number of antennas and the number of information TXRU. Notification information in the conventional antenna unit, can be seen codebookSubsetRestriction part, the transmission case is distinguished by the number of antenna ports. Therefore, the new transmission mode, where the transmission is still be distinguished by the number of antenna ports. Also, because the number of antenna ports is equal to the number of TXRU, it can be said to distinguish the case where the number of transmission TXRU. As can be seen from Table 1 above, it may be equal to the number of TXRU 4,8,16,32 or 64. At the same time, it may be utilized to add several bits in the bit string is used to select the codebook to distinguish different antenna configurations in a state the same number TXRU. As shown in the information transmission antenna changes as follows.
[0071]
[0072]
[0073]
In Table 1 since the number of identical TXRU situation may correspond to different antenna configurations, the plurality of bits are added to the front end of the bit string used to distinguish different antenna configurations. When a UE receives a bit string, UE should be taken based on the number of antenna ports and determines the bit to add antenna configuration. In the case of four antenna ports, it is assumed that the length of the string of 96 bits. Meanwhile, in Table 1, in the case of only one antenna 4TXRU configuration, the number of bits to add 0. For the case of 8 antenna ports, it is assumed that a bit string of length 109. Also, because in Table 1, there are five 8TXRU antenna configurations, the number of bits added is 3. 16, 32 and 64 in the case of antenna ports, the composition of these three cases is assumed bit mode correspondence table 8 and the case is similar to the antenna port, only bits corresponding to the size of the table becomes larger. Table 1 shows that, in the case of antenna ports 16,32,64, corresponding to the number of bits added to 1,1,0. Therefore, these three cases corresponding to the bit string length should be 219,437,872. The relationship between the added bits and antenna configuration as shown in Table 2.
[0074]
Table 2 correspondence between the bits and add antenna configuration
[0075]
[0076]
[0077]
Another method for designing codebook subset constraint is to design the codebook index for distinguishing the antenna configuration, and constrained bit set correspondence table with the codebook to select the corresponding codeword. The antenna unit represented by the following notice information after the change.
[0078]
[0079]
[0080]
In this design, the codebook subset constraint is only used to select a codeword for distinguishing between antennas rather disposed so as to add bits prior to the partial design is no longer required. In Table 1, without considering the number TXRU, there are six different antenna configurations, so there are six in the index codebook selection. Codebook selection index and the correspondence between the antenna configurations shown in Table 3.
[0081]

[0083]
As described above, selection and CSI-RS transmission mechanism disposed antennas in both schemes are different. In the first embodiment, since the parameter sequence (M TXRU , M, N, P) can be obtained directly, that is, an antenna configuration (M, N, P). Meanwhile, the parameters M TXRU and N, the total number of TXRU is found (M TXRU × P × N), so that the number of the CSI-RS (M TXRU × P × N). The CSI-RS distribution M TXRU the rows, N columns, P polarization direction dimension. However, in the second embodiment, the number TXRU constraint set can be obtained by the codebook. For antenna configuration, can be obtained by Table 2 or Table 3. Configuration (M, N, P), the number of the CSI-RS can be determined by the N and the total number of antenna TXRU CSI-RS (which is equal to the number of TXRU) and the distribution of the CSI-RS. FIG 9 is distributed in two lines, for example on the 8CSI-RS 4, which is used in the antenna parameters (1,8,4,2), (2,8,4,1), (1,4,4 , 2), (2,4,4,1) a 2D array antenna.

[0121]
Further below in conjunction with FIG signal flow of the interaction between the user side and the base station side radio communication system disclosed in the present embodiment 8 in accordance with be described in detail.
[0122]
FIG 8 is a sequence diagram illustrating a method of wireless communication in a wireless communication system according to an embodiment of the present disclosure.
[0123]
As shown, in step S101, the user transmits a connection request to the base station. 8 RRC signaling to establish an RRC connection.
[0124]
In step S102, the base station transmits an RRC connection setup signaling to the user, including the antenna element and the notification information codebook subset constraint. During transmission, the base station may select a program or programs to two transmit antenna configuration information. In one embodiment, the parameter sequence (M TXRU , M, N, P) to be transmitted explicitly. In Scheme II, the parameter sequence (M TXRU , M, N, P) and the constraints can be set or added bit codebook index obtained according to the selected codebook.
[0125]

[0126]
In step S104, the user sends signaling RCC Connection Setup Complete to the base station.
[0127]
In step S105, the base station transmits CSI-RS to the user.
[0128]
In step S106, the user performs channel estimation and CSI feedback scheme according to the feedback information and the codebook is calculated CSI. The number of the CSI-RS should M TXRU × P × N and the user information corresponding to the calculated CSI feedback.
[0129]
In step S107, the user sends CSI feedback information to the base station.
[0130]
In step S108, the base station obtains channel and feedback radio resource management and pre-coding.
[0131]
Finally, in step S109, repeating steps S105-S108. CSI-RS is transmitted from the base station to the signaling process between the radio resource management and pre-coding may be periodically performed formula.
[0132]
Below in connection with FIG. 9 to the base station antenna configuration (1,8,4,2) and examples (2,4,4,1), the base station 8 using 8CSI-RS antenna port transmission mode of operation will be described in the present invention.
[0133]
In the case where the antenna is arranged (1,8,4,2), it is assumed to use a program explicitly transmission antenna configuration. In AntennaInfoDedicated-r13, each antenna configuration corresponding parameter values ​​should be as follows: antennaNumberCountM = 8, antennaNumberCountN = 4, antennaNumberCountP = 2, antennaNumberCountMTXRU = 1. The base station parameter values ​​passed to the user, whereby the user can know the base station antenna configuration to (1,8,4,2). Signaling as shown below.
[0134]
[0135]
When Similarly, when the antenna is arranged (2,4,4,1), the base station transmits signaling shown below.
[0136]
[0137]
Or base station selection scheme using two antenna configuration to be implicitly transmitted. Due to 8, so codebooksubsetrestriction-v13xx base station should be selected n8TXAntenna-tm11-r13 transmitting antenna ports of the base station. Also, because the antenna configuration parameters (8,4,2), according to Table 2, in the case of 8TXRU, the bits should be added 010 (or the selected codebook index, the index should be in this case 011) . From this information so that users can know the parameters of the antenna (8,4,2). Plus the number that the user has TXRU base station is 8, the user can understand the overall configuration of the base station antennas (1,8,4,2). Signaling as shown below.
[0138]
[0139]
When Similarly, when the antenna is arranged (2,4,4,1), should be added to 011 bits (or codebook indices are selected index in this case should be 110), the base station transmits signaling follows Fig.
[0140]
[0141]
[0142]
When the user station receives the two ends of the antenna configuration, the user may select a corresponding codebook for CSI feedback. When the end of the base station antenna configuration to (1,8,4,2), for example, the user equipment has eight TXRU determined in the same horizontal direction, the antenna is assumed that the current Rel-12 of the same configuration, the option to use the eight antenna ports TM10 codebook, i.e.
[0143]
codebook(1,8,4,2)＝codebook8-tm10
[0144]
Accordingly, a codeword index (e.g., PMI) from the user equipment selected codebook feedback to the base station. When the base station antenna configuration for the end (2,4,4,1), for example, the user equipment determines the presence TXRU two different heights, wherein each set comprises four TXRU to correspond to the antenna port 4, thereby selecting the use of two codebook 4 antenna ports, two TXRU Furthermore, since the height difference is caused due to the phase offset, there is a relationship, the user equipment between the two sets of codebooks for example, the 4 antenna ports TM10 codebook as the codebook set in the codeword four antenna ports TM10 codebook plus a phase offset θ to obtain a second set of codebook. which is
[0145]
[Number 0001]

[0146]
Accordingly, the user equipment from the codeword index above about selected codebook (e.g., PMI) and the phase shift are fed back to the base station.
[0147]
It can be seen, when the base station side antenna configuration wherein TXRU particular configuration is not the same, the user may choose different configuration of a base station antenna end CSI feedback codebook. Meanwhile, in this example, the client process determines the CSI codebook feedback, the user actually uses M TXRU ports and the base ends of these two parameters. The base station only transmits to the user terminal M TXRU and N × P signaling, without requiring a separate M, the information N, P's. And because the base station can determine the total number of end TXRU by the number of antenna ports, the base station only needs to transmit M TXRU N × P, and wherein one of the user can determine that the corresponding antenna codebook. Therefore, in reality, the base station transmits parameters should require sequence (M users transmit TXRU part, M, N, P), or all of them, it can reduce signaling overhead of the system.
[0148]
In practical work, the user transmits an RRC connection request signaling to the base station to establish an RRC connection, then the base station transmits an RRC connection setup signaling to the user, where the base station antenna configuration can be two options as described above or a program infos added to the RRC connection establishment signaling. User configuration information according to the received antenna CSI feedback scheme for determining a codebook, and, after the user sends a RRC connection setup complete signaling to the base station. Thereafter, when the base station needs to perform channel estimation, the base station sends a CSI-RS as shown in FIG. 9 to the user. Channel measurements after a user receives a CSI-RS, and then determines the CSI feedback information at the base station sends CSI feedback scheme in accordance with previously determined and the codebook. After the completion of the channel estimation at the base station to obtain CSI feedback, and the corresponding radio resource management and pre-coding.
[0149]
