[0002] With the continuous advancement of communication technology, the demand for communication quality is becoming increasingly stringent. Traditionally, the wireless environment is an uncontrollable factor, and this uncontrollability often negatively impacts communication efficiency and reduces service quality.

To fully leverage the performance-enhancing effects of smart repeaters and RIS, beam measurement and management must be enhanced.

[0224] In addition, the antenna panel or RIS panel information may include at least one of the following: directional information of the antenna panel or RIS panel, such as the normal direction of the antenna panel or RIS panel; array element arrangement information of the antenna panel or RIS panel, etc. The array element arrangement information is used to describe the number of antenna elements included in the first dimension and the number of antenna elements included in the second dimension in the antenna panel array or RIS panel array.

[0225] Optionally, the beam adjustment capability may include at least one of the following: the frequency of beam adjustment, and the time required to complete the beam adjustment. The beam adjustment frequency may indicate the speed of beam adjustment, and may include static beam adjustment (i.e., beam adjustment is not supported), semi-static beam adjustment (i.e., beam adjustment at a slower frequency), dynamic beam adjustment (i.e., frequency adjustment at a faster frequency), etc. For example, if the "beam adjustment frequency" information is missing in the beam capability information, it may indicate that the auxiliary communication device does not have the ability to adjust the beam, or that its beam adjustment frequency is not fixed, etc. This disclosure does not limit this.

[0226] In the present disclosure, the network device can determine the direction of the beam that the antenna panel or RIS panel can process based on the normal direction of the antenna panel or RIS panel and / or the array element arrangement information of the antenna panel or RIS panel, and determine the time required for the antenna panel or RIS panel to perform beam adjustment and transmission based on the frequency of the beam adjustment and / or the time required to complete the beam adjustment, thereby controlling the intelligent relay or RIS to perform beam adjustment for a specific area or specific user.

[0227] Typically, when network equipment and terminal devices communicate, signals may undergo a complex series of processes, including reflection, refraction, scattering, diffraction, penetration, and interference. This can lead to signal attenuation and degradation of communication performance. To improve communication performance, auxiliary communication devices can be used to process signals before forwarding them, eliminating signal attenuation. When the auxiliary communication device forwards signals, the direction of the transmitted signal beam aligns with that of the terminal device, and the energy of the transmitted signal is concentrated in the same direction, signal strength is maximized, resulting in optimal communication performance.

[0228] In this disclosure, to enable auxiliary communication devices to adjust beams for different terminal devices, the intelligent auxiliary device can transmit its own beam capability information to the network device. Based on this beam capability information, the network device can determine which direction of the auxiliary communication device's beam has a better channel state. The network device can then use this information to forward beams to terminal devices that are oriented in the same direction as a beam with a good channel state. Furthermore, there can be one or more beams with a better channel state.

[0229] Step 202: Send beam configuration information to the auxiliary communication device.

[0231] In addition, the reference signal configuration information includes at least one of the following: a reference signal index, a reference signal antenna port number, a time domain location occupied by the reference signal, and a frequency domain location occupied by the reference signal. The reference signal antenna port number can be used to uniquely identify the reference signal antenna port. The reference signal index can be used to uniquely identify the reference signal.

[0232] In the present disclosure, after receiving the beam capability information sent by the auxiliary communication device, the network device can determine multiple beams with better communication performance. Thereafter, the network device can combine the multiple beams to determine the configured beam, and configure the corresponding reference signal for each configured beam to determine the configuration information of the reference signal. Then, the network device can generate beam configuration information based on the information of the configured beam, the configuration information of the reference signal, and the association information between the reference signal and the configured beam, and send this beam configuration information to the auxiliary communication device. The auxiliary communication device can determine and send the corresponding reference signal based on the beam configuration information. The terminal device can receive the corresponding reference signal, measure each corresponding reference signal, and report the measurement results to the network device. Thus, the network device can determine the beam with the best channel status based on the measurement results, and instruct the auxiliary communication device to use the beam for communication, thereby improving the communication performance.

[0233] It can be understood that when the beams supported by the auxiliary communication device are combined to determine the configuration beam, one configuration beam can correspond to a beam supported by an auxiliary communication device, or one configuration beam can correspond to a beam combination supported by an auxiliary communication device. The present disclosure does not limit this.
