Detailed Description
The technical scheme of the present disclosure is described in further detail below through the accompanying drawings and examples.
In the 5G millimeter wave networking scene, along with the movement of a user, three-stage beam scanning operation of conventional P1-P3 is executed, two panels configured on a terminal side complete beam scanning simultaneously, and the optimal receiving and transmitting beam pairs are determined.
The inventors found that two cases as shown in fig. 1 may occur due to the beam scanning by the two panels separately: the case where X Beam 1 and TX Beam 2 shown in the left part of fig. 1 come from different TRPs, and the case where Panel1 and Panel 2 shown in the right part of fig. 1 determine the optimal transmit Beam from the same TRP.
A flowchart of some embodiments of a method for detecting a connection of a terminal to an access point of the present disclosure is shown in fig. 2.
In step 210, during TRP beam scanning, the terminal determines a first beam with optimal 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 Beam21.
In some embodiments, the operation of determining the first beam may be as shown in fig. 3.
In step 311, during the process of TRP scanning with the beam having the first level width, each Panel of the terminal receives the beam having the second level width, and determines the transmit-receive beam pair of each Panel and TRP according to the data transmission quality, so as to execute 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, during beam scanning with the TRP using the third level of width, each Panel of the terminal receives with a receiving beam in the corresponding receiving-transmitting beam pair, and determines a first beam corresponding to each Panel, where the first level width is greater than the third level width. In some embodiments, the third level width is a predetermined narrow beam level width.
By the method, the first beam with optimal data transmission quality of each Panel and the TRP can be obtained based on 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 suboptimal data transmission quality of TRP and 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 Beam scanning of the TRP with the third width level, each Panel of the terminal receives with a receiving Beam in the corresponding transceiving Beam pair, determines a first Beam with optimal data transmission quality corresponding to each Panel, and determines a third Beam with suboptimal data transmission quality corresponding to at least one Panel, for example, determines the third Beam of the first Panel to be Beam13.
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 the above step 210, the identification or parameter information of the third beam may be included in the control information, so that the TRP receiving the control information is adjusted to the direction of the third beam according to the control information.
In step 230, after the TRP of the transmission control information and the receiving control information is determined to be correspondingly adjusted, the second Panel and the second Beam22 with the best data transmission quality of the TRP are determined. In some embodiments, after step 220 is performed, a predetermined period of time may be waited for TRP adjustments to improve the accuracy of subsequent detections. In some embodiments, the operation of determining the second beam with the best data transmission quality of the second Panel and the TRP may determine the current beam with the best data transmission quality of the second Panel as the second beam by scanning the Panel beamlets (the receiving beams in the transmit-receive beam pair) as shown in fig. 3.
In step 240, whether the second Beam22 is identical to the first Beam21 of the second Panel is compared, and a comparison result is determined. The comparison result includes whether the TRP corresponding to the first beam of the two Panel of the terminal is the same.
In some embodiments, if the second Beam is the same as the first Beam of the second Panel, that is, beam22=beam21, it is indicated that the Beam adjustment of the TRP corresponding to the first Panel has no effect on the optimal Beam situation of the second Panel, and it is determined that the TRP 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, that is, beam22 is not equal to Beam21, it is indicated that the Beam adjustment of the TRP corresponding to the first Panel affects the optimal Beam situation of the second Panel, and it is determined that the TRP corresponding to the first beams of the two panels of the terminal are the same.
In step 250, the comparison result is sent to the TRP corresponding to the first Panel and the second Panel, so that the TRP adopts the corresponding transmission control policy. In some embodiments, for the two cases that the TRP corresponding to the first beam of the two Panel of the terminal is the same and different, the transmission control strategies adopted by the TRP are different in beam discrimination, diversity multiplexing, and the like. In some embodiments, in the case that the TRP corresponding to the first beam of the two Panel of the terminal is different, the cooperative control information of the two TRP may be pre-stored in the corresponding transmission control policy, so that the advantages of the two Panel terminal and the multiple TRP are further exerted.
In some embodiments, the transmission control policy may be preconfigured and adjusted as needed.
By the method, whether the optimal beams of the double Panel terminals are from the same TRP can be determined through multiple scans, so that enough basis is provided for a subsequent transmission control strategy, the self-adaptive adjustment capability of the subsequent transmission control is improved, and the advantages of Multi-TRP and Multi-Panel are effectively exerted.
A schematic diagram of some embodiments of a 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 optimal data transmission quality between each Panel of the terminal and the TRP during TRP beam scanning. The terminal is a dual Panel terminal. In some embodiments, the first beam determining unit 411 may determine the first beam using any of the methods in step 210 above.
The control information transmitting unit 412 can transmit control information to the TRP corresponding to the first Panel through the first Panel of the terminal, and the TRP receiving the control information can be adjusted to be not the direction of 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 with the first Panel, so that the TRP receiving the 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 a second beam having the optimal data transmission quality between the second Panel and the TRP after transmitting the control information.
The comparison result determination unit 414 can compare whether the second Beam22 is identical to the first Beam21 of the second Panel, and thereby determine a comparison result. The comparison result includes whether the TRP corresponding to the first beam of the two Panel of the terminal is the same. In some embodiments, if the second beam is the same as the first beam of the second Panel, it is indicated that the beam adjustment of the TRP corresponding to the first Panel has no effect on the optimal beam situation of the second Panel, and it is determined that the TRP 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 situation of the second Panel, and it is determined that the TRP corresponding to the first beams of the two panels of the terminal are the same.
The result feedback unit 415 can transmit the comparison result to the TRP corresponding to the first Panel and the second Panel so that the TRP adopts the corresponding transmission control policy.
By means of the mode in the embodiment, the terminal connection detection device can determine whether the optimal beams of the dual-Panel terminal are from the same TRP through multiple scans, so that enough basis is provided for a subsequent transmission control strategy, and the self-adaptive adjustment capability of the subsequent transmission control is improved.
