According to the disclosed embodiments, Rx transmits its location information can be simultaneously transmitted to the Tx when consent connections, so that the Tx Rx is possible to know the position information. Next, Tx beamforming request information to the server based on the position information of the Tx and Rx. Next, Tx judged not acquired from the server requested information beamforming, whereby the beam training process performed between Rx. Next, when the end beam training process, Tx training the beam results reported to the server. [0066] Requesting unit 211 [0067] According to an embodiment of the present disclosure, the requesting unit 211 may send a request message to the server, requesting information beamforming. Wherein both the request information may comprise location information of the receiving side apparatus and the electronic apparatus 200.

[0070] Beam training unit 212 [0071] According to the present embodiment of the present disclosure, when performing beamforming training procedure, beam training unit 212 is further configured to perform the following operations: causing a communication unit 220 to the transmission side apparatus receives the training sequence; after each apparatus transmits a training sequence to a receiving end, causes the communication unit 220 receives the training sequence from the receiving side apparatus sent; 220 transmitting and receiving beams in each beam from the received training sequence sent by the terminal, store the obtained training, and using the stored causes the communication unit to the receiving side apparatus training sequence. [0072] According to the present embodiment of the present disclosure, when performing beamforming training procedure, the receiving side apparatus corresponding to the electronic device 200 and the electronic apparatus 200 sequentially transmits the training sequence. Each time you send training sequences are transmitted using the beam to the latest in a store. After each sending the training sequence, we are waiting for the other to send the training sequence. After each received transmission of the training sequence each other, the beam training obtained are stored. [0073] FIG 4 is a flowchart of an embodiment of a signaling beam training process of the present disclosure. The electronic device according to the present disclosure may be 200 in FIG Tx transmission side apparatus shown in FIG. 4, Rx may be the electronic device 200 corresponding to the receiving side apparatus. 4, the transmission side apparatus transmits a training sequence Tx to the receiving end device Rx. Here, since the first transmission beam after the start of training, so that the full transmit Tx training sequence may be employed to Rx antenna. In this disclosure, any algorithm known in the art may be employed to design the training sequence, the present disclosure is not limited to this. Subsequently, when receiving the training sequence Tx Rx transmitted training sequence with which the beam training, training the beam so as to obtain the R1, and stores the beam R1. Next, Rx beam by using the stored training sequence transmitted R1 to Tx. Subsequently, when receiving the training sequence Tx Rx transmitted beams using the training sequence from the training, so as to obtain the beam after training T1, T1 and stores the beam. In a similar beam during the execution of the entire training process. After Tx using the stored beam T1 transmits training sequence to Rx, Rx using the stored beam R2 transmits training sequence to Tx, ..., the Rx using the stored beam Rn transmits training sequence to Tx, Tx using the training sequence from the training beam, thereby acquiring training beam Tm, and stores the beam Tm. Then beam the end of the training process. In the beam training process, the transmission side apparatus is stored m beam Tx T1-Tm, the receiving side apparatus stores n beam Rx R1-Rn. Here, m and n are positive integers, m and n depends on the relationship between the number of training sequences transmitted. When the total number of training sequence for transmission Tx and Rx even number, m = n; the total number of the training sequence when the Tx and Rx transmitted singular, m = n-1. [0074] According to the present embodiment of the present disclosure, when performing beamforming training procedure, beam training unit 212 is further configured to perform the following operations: setting a predetermined threshold value with respect to the number, the receiving side apparatus transmits the electronic apparatus 200 and the electronic device 200 when the corresponding the total number of the training sequence reaches a predetermined threshold value, the beam training process ends. [0075] According to the present embodiment of the present disclosure, may be set on the number of times the predetermined threshold value based on practical experience, so as to set the end of the beam training process conditions. Preferably, the predetermined threshold value of about 4 or 5 times. [0076] According to the present embodiment of the present disclosure, when performing beamforming training procedure, beam training unit 212 is further configured to perform the following operations: when the last training resulting beam predetermined requirement is satisfied, the beam training process ends. Specifically, when both the beam energy and the phase amplitude obtained last training predetermined requirements are satisfied, the training process determines the end of the beam. [0077] The two conditions given above beam training process ends, but the present disclosure is not limited thereto, and other similar methods may be employed to define the conditions of the beam training process ends. [0078] As described above, according to embodiments of the present disclosure, Tx and Rx beams are sequentially transmitted training sequence, the training can be performed once after each of the beams received training sequence, the process is a process of gradually converges, so that the beam is corrected gradually. After the end of the beam training, Tx and Rx beams are corrected to a direction toward one another so as to operate on the subsequent beamforming and data transmission. At the same time, not only in training get to the beam shaped beam information when performing the receiving end of the process equipment, greatly simplifying the algorithm. Further, the beam during a training process is adaptively adjusted so as to get the best performance of beam transmission, to obtain higher transmission performance. Thus combining the advantages of adaptive beamforming and fixed codebook switch between the two beams beamforming technology to achieve higher transmission performance based on a simple algorithm. [0079] In the example shown in FIG. 4, only shows an example of transmitting a training sequence between Tx and Rx. According to the present embodiment of the present disclosure, when using the stored beam causes the communication unit 220 transmits a training sequence to the receiving side apparatus, the beam training unit 212 is further configured to perform the following operations: using the stored beam 220 causes the communication means to the receiving end with the device send training sequence and data. [0080] According to the present embodiment of the present disclosure, when each Tx or Rx transmits a training sequence, also can simultaneously transmit data, where the data may be desirable for a portion of data Tx data transmission and Rx. Further, each time the training sequence and data transmission, using the latest storage is to send the beam. As a result, no need to wait until the end of the beam training process, you can use the beam has been trained to send part of the data. In this case, although this time is not the beam training the best performance, the most accurate directivity beam, it can greatly reduce the waiting time of the data transmission. According to the present embodiment of the present disclosure, when the end beam training process, the electronic device 200 may continue to transmit the data is not finished sending to the beam training process with the electronic device 200 corresponding to the receiving side apparatus. [0081] According to the present embodiment of the present disclosure, when the communication unit 220 transmits a training sequence and data to the receiving end with the apparatus, the beam training unit 212 is further configured to perform the following operations: a training sequence that follows, in the data transmission or the data follow along with training sequence is transmitted together later. [0082] Below in conjunction with FIGS. 5 and 6 to be described in detail above two ways.

FIG 6 is a flowchart illustrating a signaling beam training according to another embodiment of the present disclosure of the process. [0083] 5, the data of the electronic device 200 follows the training sequence transmitted back together. According to the direction of the arrow, as the transmission side apparatus Tx electronic device 200 at every transmission Xianxiang reception device Rx side transmits a training sequence, followed by the data transmission, the receiving side apparatus can transmit, at each Rx Xianxiang Tx transmission side apparatus transmits a training sequence, followed by transmission data. Specifically, a first transmitted beam after the start of training, Tx may be transmitted using the full training sequence and data to the Rx antenna. Subsequently, when receiving the training sequence Tx Rx transmitted training sequence with which the beam training, training the beam so as to obtain the R1, and stores the beam R1. Next, Rx beam R1 transmits using the stored training sequence and data to Tx. Subsequently, when receiving the training sequence Tx and Rx data transmitted by using the training sequence from the training beam, so as to obtain the beam after training T1, T1 and stores the beam. In a similar beam during the execution of the entire training process. Tx using the stored beam T1 transmits a training sequence and data to Rx, Rx using the stored beam R2 transmits a training sequence and data to Tx, ..., Rx using the stored beam Rn transmitted training sequence and data to Tx, Tx using the training sequence from the training beam, thereby obtaining beam Tm after training, and stores the beam Tm. Then beam the end of the training process. [0084] 6, the electronic device 200 with a training sequence to follow later in the data transmission. According to the direction of the arrow, as the transmission side apparatus Tx electronic device 200 at every transmission reception device Rx Xianxiang data transmitting terminal, followed by transmitting a training sequence, the receiving side apparatus can transmit, at each Rx Xianxiang Tx transmission side apparatus transmits data, followed by sending the training sequence. This process is similar to FIG. 5, here omitted. [0085] In the embodiment illustrated in FIG 5 and FIG 6, although the beams T1-T (m-1) is not the best performance, the most accurate directivity beam, but they still use Tx transmits data to the Rx, such that the beam training process can be carried out simultaneously with the data transfer process, which can greatly reduce the waiting time data transmission. [0086] The storage unit 213 [0087] Notably, in the conventional beamforming training process, store only the last training beam obtained by using the beam and performs beamforming and data transmission. In the present embodiment of the disclosed embodiment, the electronic device 213 of the storage unit 200 may store the beam training obtained during training all beams, comprising a beam and the intermediate beam training obtained during the last training obtained. Accordingly, all corresponding to the beam 200 and the sink apparatus also stores the electronic device beam training obtained during training. In other words, according to an embodiment, the electronic device 200 and the electronic device 200 of the present disclosure corresponding to the receiving side apparatus capable of storing the beam training procedure "final value" and the "intermediate values." [0088] According to an embodiment of the present disclosure, the storage unit 213 is further configured to perform the following operations: the last stored as an optimum beam beam, other beams and suboptimal as the stored beam. In addition, beams may have a suboptimal or more. [0089] For example, in the example shown in FIGS. 4-6, the electronic device 200 is stored as the beam Tm optimum beam, the other beams T1-T (m-1) is stored as sub-optimal beam. Likewise, the receiving side apparatus is stored as the beam Rn optimal beam, the other beams R1-R (n-1) is stored as sub-optimal beam. [0090] According to an embodiment of the present disclosure, the storage unit 213 is further configured to perform the following operations: when storing optimum beam and the one or more beams may be suboptimal stored priority level suboptimal one or more beams simultaneously. Specifically, the storage unit 213 may perform the following operations to suboptimal beam set priority levels: priority level such that the beam after the training process first obtains the priority level of the beam falls below the beams. [0091] As shown, the beam training process, the electronic device 200 sequentially obtain a beam 4-6 T1, T2, ..., T (m-1), Tm, wherein the beams T1, T2, ..., T (m-1) suboptimal beam belongs, the priority level is therefore: T1
