However, when high-frequency communication is used, attenuation of a radio signal is large, and therefore it is necessary to form a directional beam using a beam forming technique to increase the transmission signal power in the direction. Thus, in a mobile communication system, a radio signal propagates through one beam or a plurality of beams operate in turn. The use of multiple beams can expand signal coverage.
The intermediate device of the application is based on controlling the propagation of electromagnetic waves in a communication channel by means of reflection or transmission, etc. to improve the performance of the communication system.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of an IRS enhanced multi-antenna wireless communication system.
IRS is a passive device, similar to dish antennas used in satellite receivers, that reflects signals to improve signal-to-noise ratio. The different phase shift patterns of its different meta-surfaces result in the incident signal being reflected as a light beam in different directions. IRS is a complement to traditional massive MIMO technology, unlike massive MIMO systems and cooperative relaying, although IRS also attempts to improve propagation conditions by deploying active hardware components, IRS requires little operating power and is therefore suitable for implementation in energy-limited systems. Furthermore, IRSs can naturally operate in full duplex mode without the need for expensive self-interference cancellation. Furthermore, IRSs are very thin materials that can be deployed on building facades and interior walls. Thus, once a legacy network is deployed, one or more IRSs may be flexibly deployed to mitigate detected coverage holes or to provide additional capacity in areas where needed.
The deployment of intermediate devices in conventional MIMO systems facilitates both beamforming, as shown in fig. 1, with one IRS deployed in one system to facilitate communication between multiple antenna transmitters and users. An information signal is radiated from the transmitter, a direct path for communication between the transmitter and the user is possible, and at the same time the IRS receives the information signal and will reflect this signal, the main direction of which can be controlled by means of an infrared controller. In particular, a suitable phase shift is introduced on all meta-atoms to deliberately create a coherent combination of their respective scattered signals, thereby producing a signal beam focused on the user, the larger the surface, the narrower the beam, a strategy called energy focusing.
On the other hand, if there is no direct path due to severe shadowing or blockage, the transmitter should beamform the IRS. The IRS may then act as a non-amplified full duplex relay reflecting and focusing the signal to the terminal device UE to facilitate end-to-end communication. In fig. 1, consider a scenario in which a multi-antenna transmitter serves user 1 in the presence of user 2. It is assumed that the two UEs have different security levels, wherein the message of user 1 cannot be decoded on user 2. In this case, by adjusting the phase of the scattered signal to stop the signal at user 2, destructive reflection can be performed at the IRS, a strategy called energy nulling.
With these two principles, IRSs are expected to have wide applications in various communication systems, including interference management, coverage extension, and capability improvement, such as wireless communication systems, cognitive radio networks, physical layer security systems, and the like.
The intermediate device of the present application controls waveform parameters of electromagnetic waves propagating through a communication channel by reflection, refraction, or the like to improve communication system performance, and is not limited to IRS technology.
Fig. 2 is a flow chart of an embodiment of the method of the present application.
The embodiment of the application provides a beam selection measurement reporting method, which is used in a wireless communication system, wherein the wireless communication system comprises network equipment, an intermediate equipment device and user equipment, service signals sent by the network equipment are reflected to the user equipment through the intermediate equipment device, and the method comprises the following steps:

the adjusting capability is the direction which can be adjusted to the business signal wave beam, the network equipment is configured with R time units, and the R (r=1,.. R) time units, and the network equipment controls the direction which is adjusted by the intermediate equipment to be the R.
For example, the adjustment capability of the intermediate device to the traffic signal is the phase adjustment capability to the wireless signal, i.e. different phase adjustment granularity. The intermediate device is controlled by the network device to carry out multi-bit coding, so as to realize various digital states and achieve the adjustment of a plurality of phase differences. For example, when 2 bits are encoded, four digital states {00,01,10,11} are implemented, each with a 90 degree phase difference between them, the granularity of phase adjustment is 4, and when 3 bits are encoded, 8 digital states {000,001,010,011,100,101,110,111} are implemented, the phase difference adjustment of 45 degrees is implemented, and the granularity is 8. The stronger the control capability is, the phase adjustment with large granularity can be realized, and the better information adjustment capability can be also achieved.
102, Configuring a beam management reference signal;
The network device configures beam management reference signals for the terminal. In the r-th beam direction, M r beam management reference signals are configured.
Step 103, preferable beam measurement and reporting;

Preferably, the uplink signal includes R time unit information in R time units and L r(1<Lr<Mr in the R time unit) indexes of preferred beam management reference signals.
Further, the uplink signal includes a measured value of the beam management reference signal. Preferably, the measured value is at least one of reference signal received power RSRP, reference signal received quality RSRQ, channel state information CSI, and block error rate BLER.
The uplink signal containing the index and measurement value of the beam management reference signal is carried on the uplink physical control channel or the uplink random access channel. The uplink signal is directly sent to the base station or forwarded to the base station via an intermediate device.
The uplink signal originates from the terminal equipment, and the terminal measurement obtains and comparesAnd reporting the beam management reference signal indexes of the L (L is more than or equal to 1) preferred beams and the measurement metric values of the corresponding beam management reference signals.
