Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system includes a terminal 11, a network-side device 12, and an RIS device 13, or further includes an RIS controller 14. The terminal 11 may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer) or a terminal-side Device called a notebook, a personal digital assistant (Personal Digital Assistant, PDA), a palm top, a netbook, an ultra-mobile personal Computer (ultra-mobile personal Computer, UMPC), a mobile internet appliance (Mobile Internet Device, MID), an augmented reality (augmented reality, AR)/Virtual Reality (VR) Device, a robot, a Wearable Device (weather Device), a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), a smart home (home Device with a wireless communication function, such as a refrigerator, a television, a washing machine, or a furniture), a game machine, a personal Computer (personal Computer, PC), a teller machine, or a self-service machine, and the Wearable Device includes: intelligent wrist-watch, intelligent bracelet, intelligent earphone, intelligent glasses, intelligent ornament (intelligent bracelet, intelligent ring, intelligent necklace, intelligent anklet, intelligent foot chain etc.), intelligent wrist strap, intelligent clothing etc..

Smart surfaces (Reconfigurable Intelligent Surface(s), RIS) are an emerging man-made material device. The RIS device unit can dynamically/semi-statically adjust its own electromagnetic properties to influence the reflection/refraction behavior of electromagnetic waves incident on the RIS device unit such that the electromagnetic parameters (phase or amplitude or polarization direction) of the forwarded signal (reflected signal or transmitted/refracted signal) are changed. The RIS equipment is composed of a plurality of RIS device units, and the functions of beam scanning, beam forming and the like are realized by controlling the electromagnetic characteristic states of the RIS device units and mutually overlapping the reflection/refraction behaviors of the RIS device units on electromagnetic signals in space.
The RIS device comprises a control module which interacts with the base station via a wireless or wired interface. The RIS may receive control from an upstream base station (including a host base station donor gNB, or a parent node of a previous hop node), i.e., the base station may control transmission parameters of the RIS, such as a reception/transmission beam between the RIS and the base station or between the RIS and the UE, to improve the working efficiency of the RIS.
In the network architecture shown in fig. 2, comprising 3 network nodes, the intermediate network node is a RIS device comprising a terminal module (Mobile Termination, MT) and a RIS panel. Wherein the MT may establish a connection (via a control Link) with an upstream base station, and the base station transmits control signaling to the RIS via the MT, and may control transmission/reception related parameters of a Link between the RIS device and the base station (e.g., a Backhaul (BH) Link) or a Link between the RIS and the UE (e.g., an Access (AC) Link).
NR Uu beam alignment:
taking the downstream beam alignment as an example, beam alignment is roughly divided into two stages. The first stage is to initially train the initial transmission beam from the base station to the UE when the UE accesses the network. The second stage is training the base station to UE fine transmit receive beam pair after the UE establishes a connection, and the second stage of beam training is mainly accomplished through CSI-RS measurement and channel state information (Channel State Information, CSI) feedback.
For the first phase, the base station periodically transmits a synchronization signal/physical broadcast channel signal block (or synchronization signal block) (Synchronization Signal and PBCH block, SSB) and transmits a set of SSBs in a beam scanning manner every SSB transmission period. The UE measures the reference signal carried by the SSB and reports the SSB index (index) with higher receiving energy so that the base station can determine the sending beam of the base station. The UE reports SSB index according to rules specified by the protocol, each SSB corresponds to a set of physical random access channel (Physical Random Access Channel, PRACH) resources, and the UE sends a preamble (preamble) of the initial access on the corresponding PRACH resources, and reports the corresponding SSB index on behalf of the UE. For the second phase, the Rel-15 NR Uu CSI acquisition flow is shown in FIG. 3. The base station performs CSI reporting related parameter configuration, the CSI reporting is triggered (the 'triggering' is only aimed at semi-persistent (semi-persistent) or periodic (periodic) CSI reporting), the UE performs CSI measurement and reporting according to the configuration information of the base station, and the base station adjusts transmission parameters such as uplink and downlink beams according to the UE result. Each CSI reporting configuration indicates a type of CSI reporting (CSI quality), which includes parameters indicating beams, such as CSI reference signal resource identifiers (CSI-RS Resource Index, CRI), SSB index, and the like, and includes other parameter type precoding matrix identifiers (Precoding matrix index, PMI), rank identifiers (rank index, RI), channel quality identifiers (Channel quality index, CQI), layer 1reference signal received power (Layer 1reference signal received power,L1-RSRP), signal-to-interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR), and the like.
In addition, for beam training at the base station/UE side, the base station/UE may autonomously select a training beam.
In the related art, an RIS device may be used for signal enhancement of a terminal in a scenario where information is forwarded between a base station and the terminal through a relay device such as an RIS. For example: in low-rate service, the terminal can directly communicate with the base station, and in high-rate service, the terminal can enhance signal quality with the assistance of RIS equipment to provide communication rate. Therefore, before the RIS device is scheduled to serve the terminal, the network trains the reception/transmission beam of the RIS device, and ensures the channel quality of the cascade channel of the base station-RIS-terminal. However, since the RIS device has no baseband signal processing capability, only the transfer of analog beams can be performed, and thus, the beam training method in the related art is not suitable for a scenario in which the RIS device exists.
In the embodiment of the present application, a beam training method in a scenario where an RIS device exists is defined, so that a relay device (i.e., a first device in the embodiment of the present application) can participate in beam training between a network side device, the relay device and a terminal based on a first parameter and/or a second parameter, and through the beam training process, at least one of an outgoing beam, an outgoing angle, an incoming beam and an incoming angle of the relay device can be determined.
It should be noted that, the outgoing beam in the embodiment of the present application is equal to the transmission beam, the transmission angle, and the outgoing angle; the incident beam in the embodiment of the present application is equivalent to the receiving beam, the receiving angle, and the incident angle.
The training beam in the embodiments of the present application may be referred to as "managing (managing) or scanning or traversing the beam", and the process of training the beam may be that the beam or the parameters related to the beam are switched to determine the final beam therefrom.
The transmission method, the parameter determining method, the transmission device parameter determining device, the communication equipment and the like provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings by some embodiments and application scenarios thereof.
Referring to fig. 4, in the transmission method provided in the embodiment of the present application, an execution body of the transmission method is a first device, and as shown in fig. 4, the transmission method executed by the first device may include the following steps:
step 401, the first device receives a first signal based on a first parameter and/or transmits the first signal based on a second parameter.
In one embodiment, the first device may be a relay device capable of receiving and forwarding signals, for example: RIS devices, network controlled repeaters (Network controlled repeater, NCR), etc. In the embodiment of the present application, the relay device is taken as an example of an RIS device for illustration, and optionally, the RIS device may include an active RIS device, a passive RIS device, and a hybrid RIS device. The device may include an active RIS unit and/or a passive RIS unit thereon, not specifically limited herein. If the RIS device is an active RIS device, the RIS device comprises an active unit; in the case of a passive RIS device, the RIS device comprises a passive unit; in the case of a hybrid RIS device, the RIS device comprises an active unit and a passive unit.
In one embodiment, the first device is connected to an upstream node second device (e.g., a network side device such as a base station), and the first device is connected to a downstream node third device (e.g., a terminal). The beam training process may be to adjust transmission parameters (such as a beam, a receiving angle, a sending angle, an incident angle, an outgoing angle, etc.) of at least one of the second device, the first device, and the third device may receive and/or measure the first signal sent by the second device and forwarded by the first device to obtain a measurement result, where at least one of the second device, the first device, and the third device may determine, based on the measurement result, a beam capable of meeting a communication quality requirement.
It should be noted that the overall process of training the beam may be that the second device sends a set of first signals, the first device receives and forwards the set of first signals, the third device receives and/or measures the set of first signals sent by the second device and forwarded by the first device, so as to obtain a measurement result, and then at least one of the second device, the first device, the third device, or even the core network device may obtain the measurement result, and determine a beam of at least one of the second device, the first device, and the third device according to the measurement result.
The first device sends the first signal based on the second parameter, and the first device may reflect or refract the incident first signal based on the second parameter.
Step 402, the first device sends and/or receives data information based on first information, wherein the first information comprises parameters determined based on measurement results of the first signal.
In one embodiment, the first information may include an outgoing beam or outgoing angle determined through beam training, and an incoming beam or incident angle, at which time the first device transmits and/or receives data information based on the first information, may be the first device transmitting data information based on the determined outgoing beam or outgoing angle, and/or receiving data information based on the determined incoming beam or incident angle.
In one embodiment, the beam training may be training the beam in DL. For example: the first device receives the first signal from the second device based on the first parameter and/or the first device refracts or reflects the first signal based on the second parameter to transmit the first signal to the third device, which may train at least one of the following beams:
DL transmit beam or transmit angle of the second device, e.g.: beam 1 as shown in fig. 4;
DL incident beam or angle of incidence of the first device, for example: beam 2 as shown in fig. 4;
DL exit beam or exit angle of the first device, for example: beam 3 as shown in fig. 4;
DL reception beam or transmission angle of the third device, for example: as shown by beam 4 in fig. 4.
In one embodiment, the beam training may also be training beams in UL, for example: the first device receives the first signal from the third device based on the first parameter and/or refracts or reflects the first signal based on the second parameter to transmit the first signal to the second device, at least one of the following beams may be trained:
UL receive beam of the second device;
UL receive beam of the first device;
UL transmit beam of the first device;
UL transmit beam of the third device.
In one embodiment, the beams in UL and DL may be trained separately.
In another embodiment, beams in the UL or DL may be trained, and for untrained beams, then the determination may be based on the dissimilarity of UL and DL. For example: according to reciprocity of UL and DL, the incidence angle or the incidence beam of the first device determined in DL is the emergence angle or the emergence beam of the first device in UL; the exit angle or exit beam of the first device determined in DL is the incident angle or incident beam of the first device in UL; the transmission angle or the transmission beam of the second device determined in DL is the reception angle or the reception beam of the second device in UL; the reception angle or reception beam of the third device determined in DL is the transmission angle or transmission beam of the third device in UL.
In the embodiment of the present application, the beam training in DL is exemplified, and no specific limitation is made here, and for the beam training in UL, reference may be made to the explanation of the beam training in DL.
As an alternative embodiment, the first parameter includes: at least one of an angle of incidence, an incident beam, control information of the first device;
and/or the number of the groups of groups,
the second parameter includes: at least one of an exit angle, an exit beam, and control information of the first device.
For example: the first parameter and/or the second parameter comprises at least one of: a reference signal ID for the first signal, an incident beam (beam) ID, a resource (resource) ID for the first signal.
Each incident beam or each receiving beam may correspond to an incident angle or a receiving angle, and each outgoing beam or each transmitting beam may correspond to an outgoing angle or a transmitting angle, that is, the incident/receiving beam in the embodiment of the present application may be replaced by an incident/receiving angle, and the outgoing/transmitting beam may be replaced by an outgoing/transmitting angle.
In one embodiment, the first device may be a RIS device, and the control information of the first device may be at least one of state control information of an RIS cell array, a phase matrix, and a codebook. Wherein the phase matrix may be a predefined/preconfigured/configured parameter, indexed by index. For example: the control information in the first parameter may be an index of the incident angle, and k1 incident angles are included, and the index size may be k1 index values. The control information in the second parameter may be an index of the exit angle, and k2 entrance angles are included, and the index size may be k2 index values.
It will be appreciated that the RIS device may generate the state control information/codebook for the corresponding RIS cell array by either the angle of incidence or the angle of emergence. For example, assuming a horizontal incidence angle α, a horizontal exit angle β, an array of RIS cells is a rectangular array of M x N, and adjacent RIS cells are spaced apart by λ/2. Assuming that the RIS cell at the lower left corner of the RIS cell array is numbered (0, 0) and serves as a reference point for generating the codebook, the phase difference of the repeated signal of the RIS cell numbered (i, j) relative to the repeated signal numbered (0, 0) is ipi (sin alpha-sin beta). And adjusting the state of the RIS unit (i, j) according to the phase difference, so that the RIS unit (i, j) and the forwarding signal phase of the RIS unit (0, 0) are positively overlapped, and a desired codebook is obtained.
The first parameter represents a reception or incidence parameter of the first device and the second parameter represents a transmission or reflection or refraction parameter of the first device. Wherein the number of the first parameters may be K1 and the number of the second parameters may be K2, and K1 satisfies at least one of the following:
k1 is a predefined, preconfigured, configured or network-side indicated value;
k1 is a value of 1 or more;
in the case of training at least one of the second, third and fourth parameters, K1 is equal to 1;
In the case of training the first parameter, K1 is greater than or equal to 1;
or,
k2 satisfies at least one of:
k2 is a predefined, preconfigured, configured or network-side indicated value;
k2 is a value of 1 or more;
in the case of training at least one of the first, third and fourth parameters, K2 is equal to 1;
