Description

Interference adjusting method for antenna wave beam

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for adjusting interference of an antenna beam.

Background

Currently, the third generation partnership project (3rd Generation Partnership Project,3GPP) defines that end-to-end communication can take place directly via a sidelink, i.e., PC5 connection. For example, terminal a may generate a transmission beam of terminal a through an antenna of terminal a and transmit the transmission beam to terminal B. Accordingly, the terminal B may form a reception beam of the terminal B using an antenna of the terminal B to receive a transmission beam of the terminal a, thereby implementing communication. However, when the terminal a and the terminal B communicate, there may be an interference source between the antennas of the two parties, such as other devices that are communicating, so as to interfere the communication between the terminal a and the terminal B, and affect the stability and reliability of the communication between the terminal a and the terminal B.

Therefore, in the case where there is interference between the terminal a and the terminal B, how to communicate stability and reliability is a characteristic problem of the current study.

Disclosure of Invention

The embodiment of the invention provides an interference adjustment method and device for an antenna beam, which are used for ensuring the stability and reliability of communication by adjusting the beam under the condition of interference.

In order to achieve the above purpose, the invention adopts the following technical scheme:

in a first aspect, an interference adjustment method for an antenna beam is provided, which is applied to a terminal device located in a first wave position of an antenna, and the method includes: the terminal equipment acquires control information of a user, wherein the control information of the user is used for indicating the user to instruct equipment positioned in a second wave position of the antenna to execute corresponding operation, and at least one wave position is arranged between the second wave position and the first wave position; if there is an interference source for interfering the side beam in the direction of the first wave bit pointing to the second wave bit and there is no interference source for interfering the side beam in the direction of the third wave bit of the first wave bit pointing to the antenna, the terminal device sends the side beam of the terminal device to the direction where the third wave bit is located, the side beam of the terminal device carries control information of a user, and an included angle between the direction of the first wave bit pointing to the third wave bit and the direction of the first wave bit pointing to the second wave bit is an acute angle.

Based on the method of the first aspect, it can be known that, in the case that an interference source that interferes with the side-going beam exists in the direction in which the first wave position of the antenna points to the second wave position of the antenna, the terminal device may send the side-going beam of the terminal device in the direction in which the first wave position with an acute angle to the direction in which the first wave position points to the second wave position points to the third wave position, so as to bypass the interference source by adjusting the beam direction of the antenna, thereby ensuring stability and reliability of communication.

In a possible design, the terminal device obtains control information of a user, including: responding to the operation of a user, and generating control information of a plaintext by the terminal equipment; the terminal device uses at least one item of information: and encrypting the control information of the plaintext to obtain the control information of the user. It will be appreciated that the relevant information for each wave bit is typically different, and that encrypting the relevant information for each wave bit ensures that each encryption is unique, thereby improving communication security and reducing the likelihood of information theft.

Optionally, the terminal device uses at least one item of information: the control information of the plaintext is encrypted by the related information of the first wave bit or the related information of the second wave bit to obtain the control information of the user, which comprises the following steps: the terminal equipment hashes at least one item of information to obtain a hash character string; the terminal equipment adds a prefix index to the hash character string to obtain the hash character string added with the prefix index; and the terminal equipment encrypts the control information of the plaintext by using the hash character string added with the prefix index to obtain the control information of the user.

Optionally, the information related to the first wave position includes at least one of: the identification of the first wave position, the identification of the equipment in the first wave position, the identification of the wave position adjacent to the first wave position, the identification of the equipment in the wave position adjacent to the first wave position. The information about the second wave position includes at least one of: the identification of the second wave position, the identification of the device within the second wave position, the identification of the wave position adjacent to the second wave position, the identification of the device within the wave position adjacent to the second wave position.

In a possible design, the terminal device obtains control information of a user, including: the terminal equipment receives a side beam from a fourth wave bit, wherein the side beam of the fourth wave bit carries control information of a user; and under the condition that the first wave position where the terminal equipment is positioned is not the second wave position to which the control information of the user needs to be transmitted, the terminal equipment determines the sidestream beam for forwarding the fourth wave position according to a preset rule. Wherein, preset rules are used for indicating: if the wave position indicated by the information carried in the wave beam received by the terminal equipment is not the wave position where the terminal equipment is located, the terminal equipment forwards the wave beam received by the terminal equipment; or if the wave position indicated by the information carried in the wave beam received by the terminal equipment is the wave position where the terminal equipment is located, the terminal equipment consumes the information carried in the wave beam received by the terminal equipment. In this way, the transfer of the side-row beam can be achieved so that the interference source can be bypassed so that the side-row beam can eventually be transferred to the second wave position.

In a possible design, the method of the first aspect further includes: the terminal equipment determines that an interference source for interfering the sidestream beam exists in the direction of the first wave position pointing to the second wave position; and the terminal equipment selects the direction of the first wave position pointing to the third wave position as the direction of the wave beam of the terminal in the direction of the interference source of the interference side wave beam.

Optionally, the terminal device determines that there is an interference source that interferes with the sidelobe beam in a direction in which the first wave position points to the second wave position, including: the terminal equipment transmits a plurality of detection beams of the terminal equipment in the direction that the first wave position points to the second wave position, wherein the power of the plurality of detection beams is sequentially increased according to the sequence of transmitting the plurality of detection beams, and each detection beam in the plurality of detection beams is used for indicating the equipment receiving the detection beam to return to the beam intensity of the detection beam; the terminal equipment receives a plurality of beam intensities returned by other equipment in the direction that the first wave position points to the second wave position; and the terminal equipment determines that an interference source for interfering the sidestream beam exists in the direction of the first wave bit pointing to the second wave bit according to the attenuation conditions of the plurality of wave beam intensities. For example, if there is an interference source, the multiple beam intensities are not linearly attenuated, but are non-linearly attenuated, so that it can be determined that there is an interference source that interferes with the side beam in the direction in which the first wave position points to the second wave position according to the attenuation condition of the multiple beam intensities.

It will be appreciated that the manner of determining the source of interference described above applies to each direction in which the first beam is directed to its surrounding wave positions. That is, the terminal device may transmit a plurality of probe beams to each direction, and finally determine that there is an interference source that interferes with the side-line beam in the direction in which the first wave position points to the second wave position.

Optionally, the directions in which the interference source of the interference side line beam does not exist include a plurality of directions, and the terminal device selects, as the direction of the beam of the terminal, the direction in which the first wave bit points to the third wave bit in the direction in which the interference source of the interference side line beam does not exist, including: the terminal equipment selects a direction with an included angle which is not the smallest with the direction of the first wave position pointing to the second wave position from a plurality of directions, and the direction with the included angle which is not the smallest is the direction of the first wave position pointing to the third wave position so as to avoid the influence of an interference source as far as possible.

Wherein, preset rules are used for indicating: if the wave position indicated by the information carried in the wave beam received by the terminal equipment is not the wave position where the terminal equipment is located, the terminal equipment forwards the wave beam received by the terminal equipment; or if the wave position indicated by the information carried in the wave beam received by the terminal equipment is the wave position where the terminal equipment is located, the terminal equipment consumes the information carried in the wave beam received by the terminal equipment.

To facilitate understanding of the embodiments of the present invention, a communication system suitable for use in the embodiments of the present invention will be described in detail with reference to the communication system shown in fig. 1. Fig. 1 is a schematic diagram of a communication system to which an interference adjustment method for an antenna beam according to an embodiment of the present invention is applicable.

Referring to fig. 1, an embodiment of the present invention provides a communication system, which may include: a plurality of terminal devices.

The terminal device may be a terminal having a wireless transceiving function or a chip system provided in the terminal. The terminal device may also be referred to as a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user device. The terminal device in the embodiment of the present invention may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), a vehicle-mounted terminal, an RSU with a terminal function, or the like. The terminal device of the present invention may also be an in-vehicle module, an in-vehicle component, an in-vehicle chip, or an in-vehicle unit that is built in a vehicle as one or more components or units, and the vehicle may implement the method provided by the present invention through the in-vehicle module, the in-vehicle component, the in-vehicle chip, or the in-vehicle unit. The communication between terminals may be a communication between terminals, which may also be referred to as side-by-side communication.

The terminal device is provided with a plurality of antenna panels (paths), such as M antenna panels. Each of the M antenna panels may transmit or receive a plurality of beams in a different direction, referred to as the plurality of beams of that antenna panel.

A beam refers to a special transmitting or receiving effect with directivity formed by a transmitter or receiver of a network device or terminal through an antenna array, similar to a beam formed by a flashlight converging light into one direction. The signal is sent and received in a beam mode, so that the transmission data distance of the signal can be effectively improved. The beams used for communication between terminals may also be referred to as sidelobes.

The beam may be a wide beam, or a narrow beam, or other type of beam. The technique of forming the beam may be a beamforming technique or other technique. The beamforming technique may specifically be a digital beamforming technique, an analog beamforming technique, or a hybrid digital/analog beamforming technique, etc.

The beams generally correspond to resources. For example, when performing beam measurement, the network device measures different beams through different resources, the terminal feeds back the measured resource quality, and the network device can know the quality of the corresponding beam. During data transmission, the beam can also be indicated by its corresponding resource. For example, the network device indicates a transmission configuration indication-state (state) through a transmission configuration number (transmission configuration index, TCI) field in downlink control information (downlink control information, DCI), and the terminal determines a beam corresponding to the reference resource according to the reference resource included in the TCI-state.

In a communication protocol, the beams may be characterized specifically as digital beams, analog beams, spatial filters (spatial domain filter), spatial filters (spatial filters), spatial parameters (spatial parameter), TCI-states, etc. The beam used to transmit the signal may be referred to as a transmit beam (transmission beam, or Tx beam), spatial transmit filter (spatial domain transmission filter), spatial transmit filter (spatial transmission filter), spatial transmit parameters (spatial domain transmission parameter), spatial transmit parameters (spatial transmission parameter), and the like. The beams used to receive the signals may be referred to as receive beams (or Rx beams), spatial receive filters (spatial domain reception filter), spatial receive filters (spatial reception filter), spatial receive parameters (spatial domain reception parameter), spatial receive parameters (spatial reception parameter), and the like.

It will be appreciated that embodiments of the invention are described in terms of beams in general, but that beams may alternatively be understood as other equivalent concepts and are not limited to the concepts mentioned above.

The following will describe the method in detail mainly taking the terminal device as an example.

Fig. 2 is a flow chart of an interference adjustment method for an antenna beam according to an embodiment of the present invention. The interference adjustment method of the antenna beam is suitable for the communication system and mainly relates to interaction between terminal equipment.

As shown in fig. 2, the flow of the method is specifically as follows:

s201, the terminal equipment acquires control information of a user.

Wherein the terminal device is located at a first wave position of the antenna. The first wavelength band may refer to an area that can be completely covered by the side beam of the terminal device, that is, when the terminal device is located at any position within the first wavelength band, the side beam of the terminal device can completely cover the area of the first wavelength band. However, for other wave positions adjacent to the first wave position, the sidestream wave position of the terminal device may not completely cover the area of the other wave beam.

The control information of the user is used for indicating the user to instruct the equipment located in the second wave position to execute the corresponding operation. The control information of the user may include: information encrypted for indicating a user, such as a unique identification of the encrypted user, an indication cell encrypted for indicating that the device performs a corresponding operation, and information encrypted for indicating a device that needs to perform the operation, such as a unique device identification of the device that is encrypted. And, the control information of the user may further include: the information indicating the second wavelength, such as the unique wavelength index of the second wavelength, in the plaintext is used to indicate that the control information of the user needs to be sent to the device in the second wavelength.

If the terminal device is the handset #1 and the device located in the second wave position is the handset #2, the operation may be that the handset #1 controls the handset #2 to synchronously play video or audio. At least one wave position is spaced between the second wave position and the first wave position, in this case, the side beam of the terminal device may not directly cover the second wave position, and a device in the wave position between the second wave position and the first wave position needs to forward the side beam of the terminal device to transmit the side beam of the terminal device to the second wave position.

In one possible design, in response to a user operation, the terminal device generates control information of plaintext, including: the information in the clear for indicating the user, the indication cell in the clear for indicating the device to perform the corresponding operation, and the information in the clear for indicating the device that needs to perform the operation. The terminal device may use at least one item of information: and encrypting the control information of the plaintext to obtain the control information of the user. Wherein, the related information of the first wave bit may include at least one of the following: the identification of the first wave position, the identification of the equipment in the first wave position, the identification of the wave position adjacent to the first wave position, the identification of the equipment in the wave position adjacent to the first wave position. The information about the second wave position may include at least one of: the identification of the second wave position, the identification of the device within the second wave position, the identification of the wave position adjacent to the second wave position, the identification of the device within the wave position adjacent to the second wave position. It will be appreciated that the relevant information for each wave bit is typically different, and that encrypting the relevant information for each wave bit ensures that each encryption is unique, thereby improving communication security and reducing the likelihood of information theft.

For example, the terminal device may hash the at least one item of information to obtain a hash string. The terminal device may add a prefix index to the hash string to obtain a hash string to which the prefix index is added. For example, the hash string is P1P2P3S1S2, S1S2 is used as the prefix index, and the hash string added with the prefix index is S1S2P1P2P3S1S2 or S2S1P 2P3S1S2. For another example, the hash string is P1P2P3S1S2, P3S1 is used as the prefix index, and the hash string added with the prefix index is P3S1P 2P3S1S2 or S1P3P1P2P3S1S2. For another example, the hash string is P1P2P3S1S2, P1P2 is used as the prefix index, and the hash string added with the prefix index is P1P2P3S1S2 or P2P1P2P3S1S 2. The terminal device may encrypt the control information of the plaintext using the hash string added with the prefix index, to obtain the control information of the user. At this time, the information indicating the second wavelength bit in the plain text is not encrypted, but is directly encapsulated into the control information of the user.

Alternatively, in another possible design, the terminal device may receive the sidelobe beam from the fourth wavelength band. The side beam of the fourth wave bit carries control information of the user. In the case where the first wavelength band in which the terminal device is located is not the second wavelength band to which the control information of the user needs to be transferred, for example, the terminal device may determine that the first wavelength band in which the terminal device is located is not the second wavelength band to which the control information of the user needs to be transferred according to information indicating the second wavelength band in the plain text in the control information of the user. Therefore, the terminal device may determine, according to a preset rule, to forward the sidelobe beam of the fourth wavelength bit. Wherein, preset rules are used for indicating: if the wave position indicated by the information carried in the wave beam received by the terminal equipment is not the wave position where the terminal equipment is located, the terminal equipment forwards the wave beam received by the terminal equipment; or if the wave position indicated by the information carried in the wave beam received by the terminal equipment is the wave position where the terminal equipment is located, the terminal equipment consumes the information carried in the wave beam received by the terminal equipment. In this way, the transmission or forwarding of the side beam can be achieved, so that the interference source can be bypassed, so that the side beam can finally be transmitted to the second wave position.

S202, if an interference source for interfering the side beam exists in the direction of the second wave position of the first wave position pointing to the antenna, and an interference source for interfering the side beam does not exist in the direction of the third wave position of the first wave position pointing to the antenna, the terminal equipment sends the side beam of the terminal equipment to the direction in which the third wave position is located.

The side beam of the terminal equipment carries control information of a user, and an included angle between the direction of the first wave position pointing to the third wave position and the direction of the first wave position pointing to the second wave position is an acute angle.

Specifically, the terminal device determines that an interference source for interfering the sidestream beam exists in the direction that the first wave bit points to the second wave bit. For example, the terminal device may send a plurality of probe beams of the terminal device in a direction in which the first wave position points to the second wave position, where power of the plurality of probe beams increases sequentially according to a sending sequence of the plurality of probe beams, and each of the plurality of probe beams is used to instruct a device that receives the probe beam to return to a beam intensity that receives the probe beam; the terminal equipment can receive a plurality of beam intensities returned by other equipment in the direction that the first wave position points to the second wave position; the terminal device may determine, according to attenuation conditions of the plurality of beam intensities, that an interference source that interferes with the sidelobe beam exists in a direction in which the first wave position points to the second wave position. For example, if there is an interference source, the multiple beam intensities are not linearly attenuated, but are non-linearly attenuated, so that it can be determined that there is an interference source that interferes with the side beam in the direction in which the first wave position points to the second wave position according to the attenuation condition of the multiple beam intensities.

It will be appreciated that the manner of determining the source of interference described above applies to each direction in which the first beam is directed to its surrounding wave positions. That is, the terminal device may transmit a plurality of probe beams to each direction, and finally determine that there is an interference source that interferes with the side-line beam in the direction in which the first wave position points to the second wave position. In addition, the other directions are directions in which no interference source of the interference side line beam exists, that is, directions in which no interference source of the interference side line beam exists include a plurality of directions. And the terminal equipment selects the direction of the first wave position pointing to the third wave position as the direction of the wave beam of the terminal in the direction of the interference source of the interference side wave beam. For example, the terminal device may select, from among a plurality of directions, a direction in which an angle with a direction in which the first wave position points to the second wave position is not the smallest, and the direction in which the angle is not the smallest is a direction in which the first wave position points to the third wave position, so as to avoid an influence of an interference source as much as possible. In this way, the terminal device may determine the direction in which the first wave position points to the third wave position as the direction of the beam of the terminal.

It will be appreciated that the side-row beam of a terminal device is physically the side-row beam of the terminal device, which cannot be forwarded. Therefore, the beam forwarding mentioned in the embodiment of the present invention is a logic probability, that is, information carried by the side-row beam of the terminal device is forwarded by other devices using the side-row beam of the device, which can be logically understood as being forwarded.

It will also be appreciated that after the devices in the second band receive side beams from other bands, the devices in the second band may obtain user control information therefrom. The device in the second wave position can determine that the second wave position in which the device in the second wave position is located is the second wave position to which the control information of the user needs to be transferred according to the information which is used for indicating the second wave position in the plaintext in the control information of the user. Therefore, the device in the second wave position can decrypt the control information of the user in the same way as the terminal device to obtain the information in the clear text for indicating the user, the indication information element in the clear text for indicating the device to execute the corresponding operation, and the information in the clear text for indicating the device to execute the operation. If the device in the second wave position determines that the user is a subscriber of the user according to the information used for indicating the user in the plaintext, that is, the user has permission to control the user to execute the corresponding operation, and if the device in the second wave position also indicates that the information of the device which needs to execute the operation is the information of the user according to the information used for indicating the device which needs to execute the operation in the plaintext, the device in the second wave position executes the corresponding operation according to the indication information element used for indicating the device to execute the corresponding operation in the plaintext, otherwise, the device does not execute the operation, and the flow is ended.

In summary, under the condition that an interference source for interfering the sidestream beam exists in the direction of the first wave position pointing to the second wave position, the terminal device can send the sidestream beam of the terminal device to the direction of the first wave position pointing to the third wave position, wherein the included angle between the first wave position and the direction of the first wave position pointing to the second wave position is an acute angle, so that the interference source is bypassed by adjusting the wave beam direction, and the stability and the reliability of communication are ensured. It can also be appreciated that, since the terminals can communicate directly through the beam, the network is not required, and the communication time is more flexible.

The method for adjusting interference of the antenna beam according to the embodiment of the present invention is described in detail above with reference to fig. 2. An antenna beam interference adjustment device for performing the antenna beam interference adjustment method according to the embodiment of the present invention is described in detail below with reference to fig. 3 to 4.
