Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a beam control method, device, reconfigurable metasurface, and base station host computer. Background Art

[0002] Reconfigurable Intelligence Surface (RIS) and Reconfigurable Holographic Surface (RHS) are both reconfigurable metasurfaces, which are artificial electromagnetic surface structures with programmable electromagnetic properties. They can generate the required target beam without complex phase shift circuits, thereby conveniently realizing transceivers. In addition, their low cost, low energy consumption, programmability, and easy deployment have attracted much attention, making them one of the potential enabling technologies for 6G.

[0003] The above two types of reconfigurable metasurfaces mainly include metamaterial surfaces and control modules. Applied in wireless communications, they can be used as antenna arrays or as relay devices. In order to meet the actual needs of mobile communications, reconfigurable metasurfaces need to have the ability to switch target beams in real time.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

The wireless terminal device may be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device.

[0128] The network device involved in the embodiment of the present application may be a base station, which may include multiple cells providing services for the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names.

[0130] To facilitate understanding of the embodiments of the present application, the following describes terms or backgrounds related to the embodiments of the present application:

[0131] Reconfigurable Intelligence Surface (RIS) and Reconfigurable Holographic Surface (RHS) are composed of a large number of reconfigurable independent units. RIS and RHS (hereinafter collectively referred to as "reconfigurable metasurfaces") can adjust the phase of each independent unit to control the reflection and refraction of electromagnetic waves, so that the wireless signal of the base station or the transmitting and receiving point (TRP) is reflected and refracted by the reconfigurable metasurface and the beam is aligned with the target user equipment (UE) or the target direction.

[0132] The antenna array of the 4G / 5G active antenna unit (AAU) / radio remote unit (RRU) products is basically integrated with the AAU / RRU products. The phased array and the base station share a common clock and can use a high-speed data communication protocol to transmit control commands, that is, they can be transmitted to each phased array in real time. In addition, the phase of each antenna element can be controlled by a phase shifter to realize the switching beam of the phased array.

[0133] Figure 1 This is a schematic diagram of the time slot for 5G beam control, such as Figure 1 As shown in the figure, 5G real-time beam control switching generally refers to time slot level switching, that is, at least one beam switching is completed within one time slot, and the beam switching needs to be completed within one symbol. Taking the 120KHz subcarrier interval frame structure as an example, one time slot is 125us, and the beam is switched once in each time slot, which is completed within symbol #13, that is, the actual beam switching time is no more than 8.92us, or even less.

[0134] The AAU / RRU product is internally synchronized with the base station time, and the digital phase shift can be adjusted to switch the beam in real time through the RF switch. Some active relays also need to be synchronized with the base station time. However, the reconfigurable metasurface system is simplified, and generally does not contain a clock synchronization system internally. In addition, the reconfigurable metasurface system may be composed of multiple distributed sub-arrays, and the communication with the base station uses low-speed wired or wireless protocol communication, which makes it difficult to use the base station phased array beam switching mechanism or the active relay device beam switching mechanism.

[0135] The present application provides a beam control method that can realize real-time switching reconstruction of the metasurface, change the beam direction and polarization characteristics.

[0136] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0137] Figure 2 is one of the flow charts of the beam control method provided in the embodiment of the present application, such as Figure 2 As shown, the embodiment of the present application provides a beam control method, which can be applied to a reconfigurable metasurface, including:

[0140] Step S230, receiving a trigger signal sent by the base station host computer to enable the reconfigurable metasurface codeword to take effect.

[0141] It should be noted that configuring the reconfigurable metasurface codeword can mean changing the state of some elements of the unit structure (such as diodes or varactor diodes) to change the equivalent circuit, thereby changing the equivalent dielectric constant and permeability, achieving phase, amplitude, and polarization adjustment, so that the independent units of the reconfigurable metasurface can realize the content indicated by the beam control command.

[0142] In the embodiment of the present application, the reconfigurable metasurface can parse the beam control command received from the base station host computer, and then configure the reconfigurable metasurface codeword. When receiving the trigger signal sent by the base station host computer, the configured reconfigurable metasurface codeword is made effective, thereby achieving at least one of the following: switching the reconfigurable metasurface; changing the direction of the beam; changing the polarization of the beam. If the reconfigurable metasurface is applied to a base station or a relay device, it can effectively track mobile users, ensure the quality of communication services, and support multi-user communication at different locations.

[0143] Through the beam control method of the present application, although the reconfigurable metasurface and the base station host computer are not strictly synchronized in time, the reconfigurable metasurface can be switched on and off, and the beam direction and polarization characteristics can be changed in real time even through a low-speed wired or wireless protocol. If necessary, the reconfigurable metasurface can also be controlled as needed to switch the reconfigurable metasurface on and off, change the beam direction and polarization characteristics at a specified time.

That is, in the case where the reconfigurable metasurface area is divided into a plurality of reconfigurable metasurface subarrays, the reconfigurable metasurface subarray codeword can be configured by the wave control unit corresponding to each reconfigurable metasurface subarray, and the reconfigurable metasurface can be beam controlled by the wave control unit corresponding to each reconfigurable metasurface subarray in units of each reconfigurable metasurface subarray.

That is, in the case where the reconfigurable metasurface is divided into multiple reconfigurable metasurface subarrays, a wave control agent can control multiple reconfigurable metasurface subarrays, a wave control agent parses the beam control command and sends it to the wave control unit corresponding to each reconfigurable metasurface subarray, each wave control unit is configured with a reconfigurable metasurface subarray codeword, and when the wave control agent receives a trigger signal sent by the base station host computer, it controls the wave control unit corresponding to each reconfigurable metasurface subarray to make the configured reconfigurable metasurface codeword effective.

[0160] According to the above embodiment, a beam control agent can control multiple reconfigurable metasurface subarrays through the beam control unit corresponding to each reconfigurable metasurface subarray, without the need for each beam control unit to parse the beam control command separately, which can save resources and improve processing efficiency.

[0161] Similarly, the beam control agent can transparently transmit the trigger signal to achieve rapid control, or it can process the trigger signal and send it to the beam control unit to achieve other functions, such as triggering beam changes at a specified time, or it can de-interfere with the received trigger signal to avoid triggering beam changes at inappropriate times due to environmental interference.

[0162] In all the above embodiments, the beam control command may include at least one of the following: polarization control; switch enable; beam index; beam codeword.

[0163] It should be noted that the beam index can obtain the beam codeword by looking up a table, etc. The base station can also directly configure the beam codeword. In this case, the beam control agent or beam control unit does not need to record the corresponding table of the beam index and the beam codeword.

[0164] In the case where the reconfigurable metasurface is divided into a plurality of reconfigurable metasurface sub-arrays, the beam control command may further include at least one of the following: sub-array selection; and a reconfigurable metasurface sub-array index.

[0165] The switch enables the reconfigurable metasurface to be turned on and off. When the reconfigurable metasurface is divided into a plurality of reconfigurable metasurface sub-arrays, the reconfigurable metasurface sub-arrays can be turned on and off.

[0166] It should be noted that the specific content of the beam control command is not limited to the above, and the above content can be implemented in different combinations. For example, subarray selection can be indicated in the following ways: implicitly, as an example, the subarray index is merged with the polarization control command; explicitly, the subarray index field is designed separately; mixed, different subarray control word structures are specified, such as the first segment corresponds to subarray A.

[0167] Different beam control effects can be achieved through different beam control commands, such as beam direction change, beam polarization change, reconfigurable metasurface subarray switching, etc.

[0168] Optionally, the reconfigurable metasurface may receive the beam control command and the trigger signal in a predetermined sequence.

[0169] Optionally, the beam control command may be received first and then the trigger signal may be received.

[0170] Optionally, a beam control command may be received first, and a trigger signal may be received after the reconfigurable metasurface finishes parsing the beam control command.

[0171] Optionally, the trigger signal may be a predetermined level or a predetermined sign.

[0172] Optionally, the reconfigurable metasurface can be connected to the base station host computer by wire or wirelessly.

[0173] Specifically, when the reconfigurable metasurface is provided with a wave control unit, the wave control unit can be connected to the base station host computer by wire or wirelessly. When the reconfigurable metasurface is provided with a wave control agent and a wave control unit, the wave control agent can be connected to the base station host computer by wire or wirelessly.

[0174] When the reconfigurable metasurface is applied to a base station, the reconfigurable metasurface is connected to the host computer of the base station by wire. When the reconfigurable metasurface is applied to a relay device, the reconfigurable metasurface is connected to the host computer of the base station by wireless.

[0175] It should be noted that, regardless of whether the reconfigurable metasurface is applied to a base station or a relay device, the various combinations of embodiments of the above-mentioned beam control method can be applicable.
