Detailed Description
The technical solution of the present disclosure is further described in detail by the accompanying drawings and examples.
In a 5G millimeter wave networking scene, with the movement of a user, three-stage beam scanning operation of conventional P1-P3 is performed, two panels configured at a terminal side complete beam scanning at the same time, and respective optimal transceiving beam pairs are determined.
The inventors have found that two situations as shown in fig. 1 may occur due to the two panels performing beam scanning separately: the case where X Beam1 and TX Beam2 are from different TRPs shown in the left part of fig. 1, and the case where the optimal transmission beams determined by patch 1 and patch 2 are from the same TRP shown in the right part of fig. 1.
A flow chart of some embodiments of a method for connection detection of a terminal with an access point of the present disclosure is shown in fig. 2.
In step 210, during the TRP beam scanning process, the terminal determines the first beam with the best data transmission quality for each Panel and TRP. The terminal is a dual Panel terminal. In some embodiments, the first Beam of the first Panel is denoted as Beam11 and the first Beam of the second Panel is denoted as Beam 21.
In some embodiments, the operation of determining the first beam may be as illustrated in fig. 3.
In step 311, in the process of scanning the TRP with the beam having the first level width, each patch of the terminal respectively receives with the beam having the second level width, and determines a transceiving beam pair of each patch and the TRP according to the data transmission quality, thereby performing step 312. In some embodiments, the first level width is a cell level width and the second level width is a wide level width predetermined by Panel.
In step 312, in the process of scanning the TRP with the beam of the third width level, each Panel of the terminal receives with the receiving beam in the corresponding transceiving beam pair, and determines a first beam corresponding to each Panel, where the width of the first level is greater than the width of the third level. In some embodiments, the third level width is a predetermined narrow beam level width.
By the method, the first beam with the optimal data transmission quality of each Panel and TRP can be obtained based on the wide and thin beam scanning of the TRP and the Panel, and the determination efficiency of the optimal beam is improved.
In some embodiments, a third beam with a TRP suboptimal data transmission quality with the first Panel of the terminal may also be determined during TRP scanning in a similar manner as in determining the first beam operation. In some embodiments, during the scanning of the TRP with the beams of the third width level, each Panel of the terminal receives with the receiving Beam in the corresponding transceiving Beam pair, determines the first Beam with the optimal data transmission quality corresponding to each Panel, and determines the third Beam with the suboptimal data transmission quality for at least one Panel, for example, the third Beam of the first Panel is determined to be Beam 13.
In some embodiments, the first Panel of the terminal may be any Panel, and the other Panel is the second Panel.
In step 220, control information is sent to the TRP corresponding to the first Panel through the first Panel of the terminal, wherein the TRP receiving the control information is adjusted to be in a direction other than the first beam according to the control information. In some embodiments, in the case that the third beam is determined in step 210, the identification or parameter information of the third beam may be included in the control information, so that the TRP of the received control information is adjusted to the direction of the third beam according to the control information.
In step 230, after determining that the TRP for transmitting and receiving the control information is adjusted accordingly, the second Beam22 with the best data transmission quality between the second Panel and the TRP is obtained. In some embodiments, after step 220 is performed, a predetermined time period may be waited for TRP adjustment, thereby improving the accuracy of subsequent detections. In some embodiments, the operation of determining the second beam with the optimal data transmission quality between the second patch and the TRP may be, as shown in fig. 3, determining the current beam with the optimal data transmission quality between the second patch as the second beam, again through scanning of the patch beamlets (the receive beams in the transceiver beam pair).
In step 240, the second Beam22 is compared to the first Beam21 of the second Panel for the same comparison result. The comparison result includes whether the TRPs corresponding to the first beams of the two panels of the terminal are the same.
In some embodiments, if the second Beam is the same as the first Beam of the second Panel, that is, Beam22 is equal to Beam21, it is determined that the TRP corresponding to the first Beam of the two panels of the terminal is different, which indicates that the Beam adjustment of the TRP corresponding to the first Panel does not affect the optimal Beam condition of the second Panel. If the second Beam is different from the first Beam of the second Panel, that is, Beam22 ≠ Beam21, it is determined that the TRP corresponding to the first Beam of the two panels of the terminal is the same, which indicates that the Beam adjustment of the TRP corresponding to the first Panel has an influence on the optimal Beam condition of the second Panel.
In step 250, the comparison result is sent to the TRPs corresponding to the first patch and the second patch, so that the TRPs adopt the corresponding transmission control strategies. In some embodiments, for the two cases that the TRPs corresponding to the first beams of the two panels of the terminal are the same and different, the transmission control strategies adopted by the TRPs are different in terms of beam differentiation, diversity multiplexing, and the like. In some embodiments, when the TRPs corresponding to the first beams of the two panels of the terminal are different, the cooperative control information of the two TRPs may be prestored in the corresponding transmission control policy, so that the advantages of the dual-Panel terminal and the multiple TRPs are further exerted.
In some embodiments, the transmission control policy may be preconfigured and adjusted as needed.
By the method, whether the optimal wave beams of the dual-Panel terminal are from the same TRP can be determined through multiple scanning, so that a sufficient basis is provided for a subsequent transmission control strategy, the adaptive adjustment capability of subsequent transmission control is improved, and the advantages of the Multi-TRP and the Multi-Panel are effectively exerted.
A schematic diagram of some embodiments of the terminal connection detection apparatus of the present disclosure is shown in fig. 4.
The first beam determining unit 411 can determine a first beam with the best data transmission quality for each Panel and TRP of the terminal during the TRP beam scanning process. The terminal is a dual Panel terminal. In some embodiments, the first beam determination unit 411 may determine the first beam by any one of the methods in step 210 above.
The control information sending unit 412 can send control information to the TRP corresponding to the first Panel through the first Panel of the terminal, and the TRP receiving the control information is adjusted to be in a direction other than the first beam according to the control information. In some embodiments, the control information may include identification or parameter information of a third beam with suboptimal data transmission quality from the first Panel, so that the TRP of the received control information is adjusted to the direction of the third beam according to the control information, thereby providing an explicit adjustment parameter for the TRP and reducing the processing difficulty of the TRP.
The second beam determining unit 413 can determine the second beam with the best data transmission quality of the second patch and the TRP after the control information is transmitted.
The comparison result determining unit 414 can compare whether the second Beam22 is identical to the first Beam21 of the second Panel, and thus determine a comparison result. The comparison result includes whether the TRPs corresponding to the first beams of the two panels of the terminal are the same. In some embodiments, if the second beam is the same as the first beam of the second Panel, it indicates that the beam adjustment of the TRP corresponding to the first Panel does not affect the optimal beam condition of the second Panel, and it is determined that the TRPs corresponding to the first beams of the two panels of the terminal are different. If the second beam is different from the first beam of the second Panel, it is indicated that the beam adjustment of the TRP corresponding to the first Panel affects the optimal beam condition of the second Panel, and it is determined that the TRPs corresponding to the first beams of the two panels of the terminal are the same.
The result feedback unit 415 can send the comparison result to the TRPs corresponding to the first patch and the second patch, so that the TRPs adopt the corresponding transmission control strategies.
Through the method in the above embodiment, the terminal connection detection apparatus can determine whether the optimal beams of the dual Panel terminals are from the same TRP through multiple scans, so as to provide sufficient basis for the subsequent transmission control strategy and improve the adaptive control capability of the subsequent transmission control.
