Background
Beamforming (beamforming) is a combination of antenna technology and digital signal processing technology, intended for directional signal transmission or reception. The beam forming is derived from a concept of an adaptive antenna, and the signal processing of a receiving end can form a required ideal signal by performing weighted synthesis on each path of signal received by a multi-antenna array element. This amounts to forming a concentrated beam from the antenna pattern (pattern) point of view. For example, the original omnidirectional receiving directional pattern is converted into a lobe directional pattern with a null point and the maximum direction, and the same principle is also applied to the transmitting end.

Detailed Description
The following detailed description of the embodiments of the disclosure refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Before a method for allocating a communication area of a terminal according to an embodiment of the present disclosure, an application scenario related to each embodiment of the present disclosure is described first. Application scenarios related to various embodiments of the present disclosure may include: at least two communication devices, at least one of the at least two communication devices is a device supporting multi-antenna transceiving, such as a base station, a wireless gateway device, or a mobile terminal having an antenna array, and supports a beamforming technique, and the other communication devices of the at least two communication devices may be mobile terminals communicating with the base station or the mobile terminal, the mobile terminal(s) may be single-antenna mobile terminals, or mobile terminals also having an antenna array and supporting a beamforming technique, and any of the mobile terminals may be a target terminal in the embodiments described below. The mobile terminal may include, but is not limited to: smart phones, tablet computers, smart televisions, PDAs (Personal Digital assistants), and portable computers.
In the following, a beamforming technique is introduced, and the beamforming technique is actually a technique for improving the utilization rate of the spectrum resources of the user based on the idea of Space Division Multiple Access (SDMA). Since in wireless communication, when a wireless signal is radiated in all directions in space, only a small portion of signal energy in one direction is received by a receiver as a useful signal, and most of the signal energy is not received by the corresponding receiver, but radiated to the receivers in other directions as an interference signal. The idea of space division multiplexing is to make electromagnetic waves propagate in a specific direction, so that users in different spatial directions can use all spectrum resources to communicate continuously at the same time. With the development of MIMO (Multiple-Input Multiple-Output) technology, beamforming technology is also being widely used. The MIMO technology is a technology that uses a large-scale transmitting antenna array at a transmitting end and/or a large-scale receiving antenna array at a receiving end, so that a signal is transmitted (or received) through the antenna array of the transmitting end (or the receiving end), thereby improving communication quality. Therefore, by the communication device with the antenna array, appropriate beams can be set at the transmitting end and/or the receiving end by controlling the relevant attribute parameters of the antenna array, so that better communication quality can be obtained. The following describes a method for allocating a communication area of a terminal according to an embodiment of the present disclosure.
Fig. 1 is a flowchart illustrating a communication area allocation method of a terminal according to an exemplary embodiment of the present disclosure, and as shown in fig. 1, the method may be applied to a communication device, which may be the communication device having an antenna array and supporting a beamforming technology, such as a base station, a wireless gateway, or a communication device, and the method includes:
The correspondence between the beam width, the beam angle, and the parameters of the antenna array may be a correspondence table, and the correspondence table between the beam width, the beam angle, and the parameters of the antenna array (for example, parameters such as the number of antennas, the phase difference between adjacent antennas, and the like) may be established in advance.
When a current communication device, for example, a base station, a wireless gateway device, or a mobile terminal having an antenna array needs to establish a dedicated communication area for a target terminal, a minimum beam width allowed by the antenna array of the current communication device may be determined according to the pre-established correspondence, and parameters of the antenna array corresponding to the minimum beam width recorded in the correspondence, so that the antenna array may be controlled by using the parameters, so that the width of the antenna beam is the minimum beam width, and meanwhile, each beam angle that the antenna array can radiate under the condition of the minimum beam width may be obtained according to the correspondence, so that the antenna array may be controlled to receive a received signal from the target terminal at each beam angle under the condition of the minimum beam width.
Since the radiation energy is controlled to be a beam in a specific direction by the beam forming technology, generally, the narrower the beam width is, the higher the gain of the radiation energy is, and thus the better the quality of the transmission and reception signal in the direction is, and on the other hand, the narrower the beam width is, the smaller the scanning granularity of the beam angle is. The more accurate the direction of the target terminal determined by scanning the respective beam angles through the minimum beam width. Therefore, by finding out the beam angle with the best signal quality among the received signals at a plurality of beam angles, it is possible to confirm the direction in which the target terminal is located.
Therefore, the target terminal is provided with a special communication area by combining the direction in which the target terminal is located, namely the beam angle with the best signal quality of the received signal, and the target beam width. That is, the dedicated communication area set for the target terminal in the embodiments of the present disclosure may be understood as an area that is set specifically for the angle at which the target terminal is located and the beam width required by the target terminal and is suitable for the target terminal to perform communication. Therefore, the range of the dedicated communication area can be freely set according to the angle of the target terminal and the required beam width, so that the current communication equipment can freely set a dedicated communication channel which accords with the required angle and range between the communication equipment and the target terminal.
In addition, it should be noted that, the number of the antennas and the phase difference are exemplary, but not limited to, these two parameters, and further setting of the formed beam, such as amplitude, gain, etc., may also be performed by introducing more parameters according to actual needs.
Therefore, by the technical scheme, the current communication equipment can quickly and accurately find the direction of the target terminal, and set the proper beam width for the target terminal according to the direction of the target terminal, so that a dedicated communication area specially for the target terminal can be formed, a dedicated communication channel conforming to a required angle and range can be freely set between the communication equipment and the target terminal, interference between the target terminal and other communication terminals during communication is reduced, and communication quality is improved.
Fig. 2 is a flowchart of a communication area allocation method for a terminal according to the embodiment shown in fig. 1, and as shown in fig. 2, the step 101 of controlling an antenna array to receive a received signal from a target terminal at a plurality of beam angles respectively in the case of a minimum beam width according to a pre-established correspondence relationship between a beam width, a beam angle and parameters of the antenna array may include the following steps:
The beam forming technology mainly utilizes the wave interference principle, namely when two lines of waves generated by two wave sources interfere with each other, two lines of waves in some directions are mutually enhanced, and two lines of waves in some directions are just counteracted. In the beam forming technology, each antenna of the antenna array is a wave source, so that there are many wave sources, and by precisely controlling the relative phase between the electromagnetic waves transmitted/received by the wave sources, the transmission/reception gain of the electromagnetic waves can be concentrated in one direction (i.e. where the receiver/transmitter is located), and the transmission/reception gain of the electromagnetic waves is small elsewhere (i.e. interference to other receivers is reduced/the chance of interference by other transmitters is reduced). In addition, in the beamforming technique, the width of a formed beam is narrower as the number of antennas used is larger.
Therefore, in the corresponding relationship, the number of antennas corresponding to the minimum beam width is the maximum number of antennas of the antenna array, so that the antenna array can be controlled to form a beam with the minimum beam width according to the number of antennas. And under the condition of the minimum beam width, acquiring a phase difference between adjacent antennas corresponding to each beam angle under the condition of the minimum beam width in the corresponding relation to traverse each beam angle, so as to enable the antenna array to receive the receiving signals sent by the target terminal at the plurality of beam angles respectively under the condition of the minimum beam width.
Fig. 3 is a flowchart of a communication area allocation method for a terminal according to the embodiment shown in fig. 1, where as shown in fig. 3, the step 102 of determining the direction of the target terminal according to the signal quality of the received signals received at the multiple beam angles may include the following steps:
Wherein a higher SNR indicates a higher signal quality, and the signal quality may also take into account other parameters besides the SNR.
In step 1022, a target beam angle is determined among the plurality of beam angles, where the target beam angle is the beam angle with the highest signal quality of the received signal.
Fig. 4 is a flowchart of a method for allocating a communication area of a terminal according to the embodiment shown in fig. 1, where as shown in fig. 4, the step 103 of setting an exclusive communication area for a target terminal according to a direction in which the target terminal is located and a target beam width required by the target terminal may include the following steps:
and step 1031, obtaining a beam width required by the target terminal.
And step 1032, setting the area with the width of the target beam width in the direction of the target terminal as the exclusive communication area of the target terminal.
Wherein, the obtaining of the beam width required by the target terminal in step 1031 may include the following two ways:
firstly, receiving a target beam width sent by a target terminal; alternatively, the first and second liquid crystal display panels may be,
secondly, acquiring the terminal model of the target terminal;
and acquiring preset beam width corresponding to the terminal model as target beam width.
That is, it may be understood that the target beam width required by the target terminal may be set by the target terminal, so that the current communication device may receive the target beam width sent by the target terminal, or the target beam width may also be set in the current communication device in advance, for example, the beam width required for different terminal models is set in advance in the current communication device, and the corresponding current communication device may first obtain the terminal model of the target terminal, so that the preset beam width corresponding to the terminal model of the target terminal may be obtained as the target beam width.
In summary, according to the above technical solution, the current communication device can quickly and accurately find the direction of the target terminal, and set a suitable beam width for the target terminal according to the direction of the target terminal, so that a dedicated communication area dedicated to the target terminal can be formed, and a dedicated communication channel conforming to a required angle and range can be freely set between the communication device and the target terminal, so as to reduce interference between the target terminal and other communication terminals during communication, and improve communication quality.
