Example (b):
a beamforming scheme according to an embodiment of the present invention is specifically described below with reference to fig. 4 and 5.
Fig. 4 shows a schematic diagram of switching of beamforming vectors according to an embodiment of the present invention.
As shown in FIG. 4, a cell covered by the base station 402 is divided into 8 coverage areas, which are f1 area between 0-45 °, f2 area between 45-90 °, f3 area between 90-135 °, f4 area between 135-180 °, f5 area between 180-225 °, f6 area between 225-270 °, f7 area between 270-315 °, and f8 area between 315-360 °.
Since the terminal device 404 stays in the f1 area, through the data interaction process 406 between the base station 402 and the terminal device 404, the base station 402 can determine that the beamforming vector is 400 and serves as an initial beamforming vector, and when it is detected that the beamforming vector needs to be switched next time, the preset priority relationship among a plurality of beamforming vectors to be switched is determined according to the coverage area of the initial beamforming vector before switching.
Fig. 5 shows a schematic diagram of switching of beamforming vectors according to an embodiment of the present invention.
As shown in fig. 5, when detecting that the terminal device 404 needs to reconfigure the measurement resources of the beamforming vector, the measurement resources of each beam are determined according to the time domain priority order. Wherein the f8 region and the f2 region are a first beamforming vector group whose measurement resources are most prioritized in the time domain, the f7 region and the f3 region are a second beamforming vector group whose measurement resources are immediately after the first beamforming vector group in the time domain, the f6 region and the f4 region are a third beamforming vector group whose measurement resources are immediately after the second beamforming vector group in the time domain, and the f5 region is a fourth beamforming vector group whose measurement resources are immediately after the third beamforming vector group in the time domain. The terminal equipment firstly measures the measurement resources of an f8 area and the measurement resources of an f2 area according to a first priority, if the wireless communication quality requirements can be met, the beam numbers with the best channel quality in the two areas are reported, if neither of the two areas can meet the wireless communication quality requirements, the terminal equipment measures the measurement resources of the beamforming vectors respectively configured in the f3 area and the f7 area according to a second priority, if the wireless communication quality requirements can be met, the beam numbers with the best channel quality in the four areas are reported, if the wireless communication quality requirements still cannot be met, the terminal equipment measures the measurement resources of the beamforming vectors respectively configured in the f4 area and the f6 area according to a third priority, if the wireless communication quality requirements can be met, the beam numbers with the best channel quality in the six areas are reported, and if the wireless communication quality requirements still cannot be met, the terminal device measures the measurement resource of the beamforming vector configured in the f5 area according to the fourth priority, and reports the beam number with the best channel quality among the seven.
As shown in fig. 5, to further optimize the efficiency of the beamforming scheme, the location information reported by the terminal device 404 is obtained, and then it is predicted that the terminal device 404 moves to the f8 area according to the moving direction 408, and the terminal device moving to the new location is denoted as 404 ', the terminal device 404' preferentially measures the measurement resources of the beamforming vector 400 configured in the f8 area, and when it is determined that the wireless communication connection quality is greater than or equal to the preset wireless communication connection quality according to the reference signal (implemented based on the data interaction process 406), the terminal device 404 'and the base station 402 determine that the beamforming vector 400 points to the f8 area, that is, the beamforming of the communication cell in fig. 4 rotates 45 ° counterclockwise, and since the moving direction 408 of the terminal device 404' is counterclockwise, the priorities decrease in a counterclockwise order, for example, the priority of the f8 area is higher than the f7 area, the priority of the f7 area is higher than that of the f6 area, the priority of the f6 area is higher than that of the f5 area, the priority of the f5 area is higher than that of the f4 area, the priority of the f4 area is higher than that of the f3 area, and the priority of the f2 area is the lowest, wherein the priorities of the areas and the priorities of the beamforming vectors are priorities corresponding to the fact that the terminal equipment searches for the measurement resources and feeds back and reports the measurement resources.
The technical scheme of the invention is explained in detail in the above with reference to the accompanying drawings, and the invention provides a beamforming scheme, by configuring the measurement resource of the beamforming vector to be switched according to the preset priority, because the preset priority is determined according to the change of the geographical position of the terminal equipment, the beam forming vector meeting the communication requirement of the terminal equipment can be determined as soon as possible by configuring the measurement resource according to the preset priority, namely the wireless carrier is adjusted to focus on the coverage area to which the user belongs after moving, the mobile terminal realizes a handshake interaction process by reporting the reference signal to the base station, and then instructs the base station equipment to end the switching of the beamforming vectors, so that the configuration efficiency of the beamforming vectors is improved, the communication time delay and the power consumption are reduced, the frequency spectrum resource utilization rate and the data throughput are improved, and the use experience of a user is also improved.
