After intermediate nodes such as a repeater, an intelligent super surface and the like are introduced into a mobile communication NR system, the intermediate nodes can realize the functions of beam management and handover. A control link is arranged between the network equipment and the intermediate node and used for controlling the intermediate node to control the beam direction, and a return link is also arranged between the network equipment and the intermediate node and used for transmitting a return signal to the intermediate node and then forwarding the return signal to the terminal equipment. After the network device sends the control information to the intermediate node through the control link, the intermediate node receives the control information and then performs beam switching.

Considering that the coverage area of the coverage hole of the intermediate node is limited, the intermediate node can be segmented, each block covers different coverage areas respectively, beam indication of the intermediate node in different areas is applied to terminals in different coverage areas, so that the terminals in different coverage areas can all receive beams from the intermediate node, the beams are used for sending and receiving data, signaling overhead is reduced, and the method is suitable for a scene of using RIS to conduct wide beam coverage. For example, fig. 2 is a multi-zone application scenario diagram, where the multiple coverage areas, such as areas 1-4, correspond to 4 areas within the coverage area of the base station. The best existing beam directions are different for each region, and when RIS (intelligent super surface) therein is divided into a plurality of blocks, each block RIS may be set as one intermediate node, and accordingly, each block RIS contains at least 1 beam direction.

The embodiment of the application provides a method and equipment for beam indication of a wireless communication system, wherein the wireless communication system comprises network equipment, intermediate node equipment and user equipment; and the service signal sent by the network equipment is transmitted to the user equipment through the intermediate node equipment. The terminal receives first configuration information, wherein the first configuration information is used for indicating a region identifier and a reference signal resource or a reference signal identifier in a region corresponding to the region identifier; the intermediate node receives the reference signal resource, and the intermediate node also receives second configuration information, wherein the second configuration information indicates the reference signal resource in the region identifier or the beam information or the beam identifier information corresponding to the reference signal identifier, and is used for regulating and controlling the beam from the base station according to the beam information or the beam identifier information.

And the terminal acquires beam information according to the second downlink control signaling and is used for transmitting and receiving data.

The intermediate node receives a first downlink control signaling, where the first downlink control signaling is used to indicate a beam or beam identification information corresponding to the intermediate node.

The first downlink control signaling is intermediate node dedicated signaling, and is used for indicating a beam or beam identification information corresponding to the intermediate node. Or, the first downlink control signaling is multicast signaling, which is used for indicating the area identification of the intermediate node and the corresponding wave beam or wave beam identification information.

Or the second downlink control signaling is multicast signaling, and is used for indicating the area identification of the terminal and the corresponding wave beam or wave beam identification information.

Preferably, the terminal device detects and receives the first configuration information and/or the second downlink control signaling by using the geographic location information.

Fig. 3 is a flowchart of an embodiment of the method for a network device.

The method of the first aspect of the present application is used for a network device, and comprises the following steps 201 to 204:

step 201, determining first configuration information, where the first configuration information is used to indicate a region identifier and corresponding reference signal information.

Preferably, the reference signal information includes at least one of the following information: reference signal resources, reference signal identification.

Fig. 4 is a schematic structural diagram of a first configuration information, where indication content of the first configuration information is shown in the following diagram, and the indication content is used to indicate a reference signal resource or a reference signal identifier corresponding to each area from a base station.

The first configuration information is sent in two ways: the first is that the first configuration information includes beam identifiers of all areas in the coverage cell of the base station, and the beam identifiers are simultaneously sent to the terminals in all areas through a high-layer signaling. For example, the base station sends RRC or MAC layer signaling or physical layer signaling indicating the following information:

zone 1: { RS 1, RS2, RS3, …, RS N }, wherein RS N (n=1, …, N) represents the reference signal resource or reference signal resource identity in region 1;

zone 2: { RS 1, RS2, RS3, …, RS N }, wherein RS N (n=1, …, N) represents the reference signal resource or reference signal resource identity in region 2;

……；

Zone M: { RS 1, RS2, RS3, …, RS N }, where RS N (n=1, …, N) represents the reference signal resource or reference signal resource identity in the region M.

The second is that each area corresponds to an RNTI or a detection time-frequency resource for detecting the first configuration information, and the first configuration information detected by the terminal by using the detection RNTI or the time-frequency resource corresponding to the area comprises beam information corresponding to the area.

For example, in a coverage area of a fixed base station, M areas are included, an area identifier RNTI for detecting the first configuration information is rnti_zon1, rnti_zon2, rnti_zon3, or resources for detecting the first configuration information are distributed as resource 1, resource 2, and resource 3, a UE in area 1 detects that the first configuration information only includes reference signal configuration information corresponding to area 1 by using rnti_zon1 or resource 1, a UE in area 2 detects that the first configuration information only includes reference signal configuration information corresponding to area 2 by using rnti_zon2 or resource 2, and a UE in area 3 detects that the first configuration information only includes reference signal configuration information corresponding to area 3 by using rnti_zon3 or resource 3. And the terminal detects the downlink control information scrambled by the RNTI_zone identifiers 1 to 4 and acquires the reference signal information corresponding to the zone identifiers 1 to 4.

Step 202, determining second configuration information, where the second configuration information is used to indicate beam information corresponding to the reference signal information.

Fig. 5 is a schematic diagram of a second configuration information structure, and the content indicated by the second configuration information is described in the following diagram.

For example, the base station indicates the reference signal resource information of the coverage area of the terminal 4, the segmented intermediate node 1 corresponds to the coverage area of the coverage area 1, receives the reference signal resource information { RS1, RS2, RS3, RS4} of the coverage area 1, receives the first downlink control signaling from the base station, indicates the beam information or the beam identification { beam1, beam2, beam3, beam4} corresponding to the reference signal resource information, the segmented intermediate node 2 corresponds to the coverage area of the coverage area 2, receives the reference signal resource information { RS1, RS2, RS3, RS4} of the coverage area 2, receives the second configuration information from the base station, indicates the beam information or the beam identification { beam1, beam2, beam3, beam4} corresponding to the reference signal resource information, and so on, the coverage of the coverage area of the 4 coverage area is realized.

The second configuration information is configured by RRC signaling/MAC layer signaling, and there are two ways to indicate:

Mode 1: and the intermediate node special signaling configuration indicates the reference signal resource corresponding to each intermediate node and the corresponding regulation and control beam information.

Mode 2: the common signaling is sent to all intermediate nodes, for example, the base station sends RRC or MAC layer signaling indicating the following information:

intermediate node 1: { RS 1: beam1, RS2: beam 2, …, RS N: beam N, where RS N (n=1, …, N) represents a reference signal resource or a reference signal resource identity in region 1, beam N represents adjusted beam information for the corresponding reference signal resource;

intermediate node 2: { RS 1: beam1, RS2: beam 2, …, RS N: beam N, where beam N (n=1, …, N) represents the reference signal resource or reference signal resource identity in region 2, beam N represents the adjusted beam information for the corresponding reference signal resource;

……；

intermediate node M: { RS 1: beam1, RS2: beam 2, …, RS N: beam N, where beam N (n=1, …, N) represents a reference signal resource or a reference signal resource identification in the region M, and beam N represents adjusted beam information for the corresponding reference signal resource.

Step 203, receiving signal quality measurement information, and determining an actual reference signal of an area where the terminal equipment is located.

Information of the signal quality measurement is from the terminal device.

Step 204, sending a first downlink control signaling, indicating beam information corresponding to the actual reference signal to an intermediate node, and/or sending a second downlink control signaling, and indicating beam information corresponding to the actual reference signal of an area where the terminal equipment is located to the terminal equipment.

The first downlink control signaling is intermediate node dedicated signaling or multicast signaling. The first downlink control signaling may be intermediate node specific information, and the downlink control signaling scrambled with the identity ris_rnti of the intermediate node is used to indicate regulatory beam information corresponding to the reference signal resource. The first downlink control signaling may also be multicast information, and the first downlink control signaling is block information scrambled with a common RNTI (rs_rnti), where each block indicates regulatory beam information for each intermediate node, and a starting position and a length of each block are configured by higher layer signaling.

The second downlink control signaling is a terminal equipment dedicated signaling or a multicast signaling. The second downlink control signaling is a terminal dedicated signaling, and the second downlink control signaling includes a beam identifier of the terminal device. Or, the second downlink control signaling is multicast signaling, and includes a plurality of indication blocks, where each indication block includes a terminal device identifier of at least one area and corresponding beam information, or each indication block includes at least one area identifier where the terminal device is located and corresponding beam information.

step 301, determining second configuration information, where the second configuration information is used to indicate beam information corresponding to the reference signal information.

The intermediate node receives the reference signal resource or the reference signal identifier corresponding to the region identifier respectively, and receives second configuration information from the base station, and instructs the intermediate node to perform beam regulation on the reference signal resource according to the beam information.

Step 302, receiving a first downlink control signaling, and determining beam information corresponding to an actual reference signal of an area where the terminal equipment is located according to the first downlink control signaling, where the beam information is used for data transmission with the terminal.

Preferably, the first downlink control signaling indicates beam information corresponding to the intermediate node.

Step 303, forwarding downlink service data to the terminal device and receiving uplink service data from the terminal device through the beam indicated by the first downlink control signaling.

Fig. 7 is a flowchart of an embodiment of the method of the present application for a terminal device.

Step 403, receiving a second downlink control signaling, and determining beam information corresponding to an actual reference signal of an area where the terminal equipment is located according to the second downlink control signaling.

Preferably, the terminal equipment determines the area identifier by using a positioning mode; the second downlink control signaling contains a beam identifier of the terminal device. Particularly, the terminal with positioning capability can directly adopt the RNTI of the area to detect the downlink control channel according to the geographic position information, so that the power loss of the detection channel is reduced.

Or the second downlink control signaling indicates the area identifier and the corresponding beam information of the terminal equipment.
