The present exemplary embodiment will be described in detail below with reference to the accompanying drawings and examples.
Fig. 1 illustrates an exemplary communication system architecture of a communication method or a communication device to which intelligent surface-assisted frequency hopping transmissions in embodiments of the present disclosure may be applied.
As shown in fig. 1, the system architecture includes: intelligent surface 100, terminal device 101, and network device 102.
The network device 102 in embodiments of the present disclosure may be various base stations or other network element devices in a communication system (e.g., a 6G communication system). The terminal device 101 in embodiments of the present disclosure may be a variety of electronic devices including, but not limited to, smartphones, tablet computers, laptop portable computers, desktop computers, wearable devices, augmented reality devices, virtual reality devices, and the like.

Under the above communication system architecture, the embodiment of the disclosure provides a communication method for intelligent surface-assisted frequency hopping transmission, which can be applied to, but is not limited to, intelligent surfaces in a 6G communication system. The method may be performed by any electronic device having computing processing capabilities.
Fig. 2 shows a flowchart of a communication method of intelligent surface-assisted frequency hopping transmission in an embodiment of the disclosure, and as shown in fig. 2, the communication method of intelligent surface-assisted frequency hopping transmission provided in the embodiment of the disclosure includes the following steps:
step S202, obtaining communication parameter information of uplink information frequency hopping transmission, wherein the communication parameter information comprises: incoming wave angle information for uplink information transmission and time-frequency resource position information for uplink information frequency hopping transmission.
It should be noted that, when the terminal device adopts the frequency hopping transmission mode to transmit the uplink information, the terminal device may send the uplink information at multiple frequency domain positions, where the terminal device may correspond to continuous or discontinuous time-frequency resources when transmitting the uplink information at each frequency domain position, so that in order to enable the intelligent surface to generate a reflection beam for reflecting the uplink information of the terminal device to the network device at each group of time-frequency resource positions, each group of time-frequency resource positions for frequency hopping transmission of the uplink information needs to determine electromagnetic parameters for adjusting each electromagnetic unit on the intelligent surface. Since the reflected beam is related to the incident angle of the incident beam, it is also necessary to acquire incoming wave angle information for uplink information transmission.
In a specific implementation, in the step S202, communication parameter information such as incoming wave angle information of uplink information transmission, time-frequency resource location information of uplink information frequency hopping transmission, and the like may be obtained by demodulating downlink control information of the network device or other related information sent by the network device. In practical applications, those skilled in the art may obtain the communication parameter information in other ways, and the manner of obtaining the communication parameter information is not specifically limited in this disclosure.
In some embodiments, when the frequency hopping transmission includes two frequency domain locations, the time-frequency domain resource location information may include: first frequency domain position information, first time domain information, second frequency domain position information, second time domain information; the first time domain information refers to continuous or different continuous time domain resources corresponding to the uplink information transmission of the terminal equipment at the first frequency domain position; the second time domain information refers to continuous or discontinuous time domain resources corresponding to the uplink information transmission of the terminal equipment at the second frequency domain position.
In some embodiments, the continuous or discontinuous time-frequency resource corresponding to the uplink information transmission performed by the terminal device at each frequency domain position may include a plurality of slots or a plurality of symbols.
Step S204, according to the incoming wave angle information of the uplink information transmission and the time-frequency resource position of the uplink information frequency hopping transmission, determining an electromagnetic unit adjustment parameter set of the intelligent surface at each group of time-frequency domain resource position.
After obtaining the incoming wave angle information of uplink information transmission and the frequency domain position information of each group of time-frequency resources of uplink information frequency hopping transmission, determining an adjustment parameter group for adjusting electromagnetic parameters of each electromagnetic unit on the intelligent surface at each group of time-frequency resource positions.
In some embodiments, when the frequency hopping transmission includes two frequency domain positions, the electromagnetic unit adjustment parameter set includes: a first electromagnetic unit adjustment parameter set, a second electromagnetic unit adjustment parameter set; the intelligent surface can determine a first electromagnetic unit adjustment parameter set according to incoming wave angle information transmitted by uplink information and one or more of first time domain information and first frequency domain position information; the intelligent surface may determine the second electromagnetic unit adjustment parameter set according to the incoming wave angle information transmitted by the uplink information and one or more of the second time domain information and the second frequency domain position information.
Step S206, at each group of time-frequency domain resource positions, respectively adjusting electromagnetic parameters of each electromagnetic unit on the intelligent surface according to the determined electromagnetic unit adjustment parameter groups so as to form a reflection beam for transmitting uplink information of each group of time-frequency domain resource positions to the network equipment.
After determining the adjustment parameter sets for adjusting the electromagnetic parameters of each electromagnetic unit on the intelligent surface, in each set of time-frequency domain resource positions, the electromagnetic parameters of each electromagnetic unit on the intelligent surface can be adjusted according to the electromagnetic unit adjustment parameter sets of the corresponding time-frequency resource positions, so as to form a reflection beam for transmitting the uplink information of each set of time-frequency domain resource positions to the network device.
It should be noted that, in the implementation, at each set of time-frequency resource positions, electromagnetic parameters of each electromagnetic unit on the intelligent surface may be adjusted, or may not be adjusted, for example, at some frequency domain positions with the same or similar frequency domain characteristics, electromagnetic parameters of the intelligent surface may not change much or not, and then the electromagnetic parameters of the intelligent surface need not be adjusted; alternatively, in some scenarios, electromagnetic parameters of the smart surface may not be adjusted in view of other factors.
In some embodiments, in the communication device for intelligent surface-assisted frequency hopping transmission provided in the embodiments of the present disclosure, the adjustment of the phase and/or amplitude of the reflected beam may be achieved by adjusting electromagnetic parameters of each electromagnetic unit on the intelligent surface. By adjusting the phase or amplitude of the reflected beam, the reflected beam can transmit the uplink information of the terminal device at each group of time-frequency resource positions to the network device.
In some embodiments, in the communication device for intelligent surface-assisted frequency hopping transmission provided in the embodiments of the present disclosure, in each set of time-frequency domain resource positions, after electromagnetic parameters of each electromagnetic unit on an intelligent surface are adjusted according to a determined electromagnetic unit adjustment parameter set, a reflection beam in a target direction is formed, where the target direction is a direction in which the intelligent surface points to a network device. In the embodiment of the disclosure, electromagnetic parameters of each electromagnetic unit on the intelligent surface are adjusted at each frequency domain position, so that the direction of the reflected beam corresponding to each group of time-frequency resource positions is the direction that the intelligent surface points to the network device, and uplink information can be sent to the network device through the reflected beam.
As can be seen from the foregoing, in the communication method for intelligent surface-assisted frequency hopping transmission provided in the embodiment of the present invention, for each set of time-frequency resource location information for frequency hopping transmission of uplink information, an adjustment parameter set for adjusting electromagnetic parameters of each electromagnetic unit on the intelligent surface at each set of time-frequency resource locations is determined according to incoming wave angle information for uplink information transmission, and then, at each set of time-frequency resource locations, electromagnetic parameters of each electromagnetic unit on the intelligent surface are adjusted according to the determined electromagnetic unit adjustment parameter set, so as to form a reflection beam for transmitting uplink information of each set of time-frequency resource locations to network equipment. According to the embodiment of the disclosure, the intelligent surface can assist in frequency hopping transmission of uplink information, so that frequency diversity gain is obtained more fully, and the coverage performance and the transmission quality of the uplink information are improved.
The following describes in detail a communication method of intelligent surface-assisted frequency hopping transmission provided in the embodiments of the present disclosure, taking a first frequency domain position and a second frequency domain position of uplink information frequency hopping transmission as an example.
Fig. 3 shows a flowchart of a communication method of intelligent surface-assisted frequency hopping transmission taking two frequency domain positions as an example in an embodiment of the disclosure, and as shown in fig. 3, specifically includes:
in step S302, the intelligent surface obtains incoming wave angle information, first frequency domain position information, second frequency domain position information, first time domain information and second time domain information of uplink information frequency hopping transmission.

The first time domain information and the second time domain information may include a plurality of symbols and a plurality of slots, which is not limited in this disclosure.
It should be noted that, the communication method for intelligent surface assisted frequency hopping transmission provided in the embodiments of the present disclosure is applicable to frequency hopping transmission of uplink information at two or more frequency domain locations, so that, in implementation, the intelligent surface may further obtain third frequency domain location information and third time domain information, or more sets of time-frequency resource locations, which are specifically related to configuration of a network device, which is not limited in the present disclosure.

The first electromagnetic unit adjustment parameter set and the second electromagnetic unit adjustment parameter set are used for adjusting electromagnetic parameters of each electromagnetic unit on the intelligent surface, and further adjusting at least one of phase and amplitude of the reflected wave.
In step S308, the intelligent surface adjusts electromagnetic parameters of each electromagnetic unit on the intelligent surface according to the first electromagnetic unit adjustment parameter set, so that the reflected beam formed by the intelligent surface transmits the uplink information of the terminal device in the first frequency domain position and the first time domain to the network device.
In a specific implementation, the electromagnetic unit on the intelligent surface may have the same or similar frequency domain characteristics at the first frequency domain position and the second frequency domain position, and specific values of each parameter in the first electromagnetic unit adjustment parameter set and the second electromagnetic unit adjustment parameter set may be the same.
In step S310, the intelligent surface adjusts electromagnetic parameters of each electromagnetic unit on the intelligent surface according to the second electromagnetic unit adjustment parameter set, so that the reflected beam formed by the intelligent surface transmits the uplink information of the terminal device in the second frequency domain position and the second time domain to the network device.
When the intelligent surface adjusts the electromagnetic unit of the intelligent surface according to the first electromagnetic unit adjusting parameter group, reflected electromagnetic waves pointing to the target direction can be formed at the first frequency domain position; when the intelligent surface adjusts the electromagnetic unit of the intelligent surface according to the second electromagnetic unit adjusting parameter set, the reflected electromagnetic wave pointing to the target direction can be formed at the second frequency domain position.
