[0121] For method 4.3, for example, Figure 1In the system architecture shown, a forwarding resource can be expressed as {beamindex x, RIS block q, time resource y}. In the forwarding resource, beamindex x is the beam index x, RIS block q is the sub-block identifier q, and time resource y is the time domain resource identifier y. In the forwarding resource, the time domain resource identifier y corresponds to the beam index x and the sub-block identifier q, and the beam index x corresponds to the sub-block identifier q.

In the forwarding resource, beamindex x is the beam index x, RIS r is the smart metasurface panel identifier r, and time resource y is the time domain resource identifier y. In the forwarding resource, the time domain resource identifier y corresponds to the beam index x and the smart metasurface panel identifier r, and the beam index x corresponds to the smart metasurface panel identifier r.

In the forwarding resource, beamindex x is the beam index x, RIS block q is the sub-block identifier q, RIS r is the smart metasurface panel identifier r, and time resource y is the time domain resource identifier y. RIS blockq&RIS r can be used to identify the smart metasurface panel identified by the smart metasurface panel identifier r and the sub-block identified by the sub-block identifier q on the smart metasurface panel identified by the smart metasurface panel identifier r. In the forwarding resource, the time domain resource identifier y corresponds to the beam index x and corresponds to the sub-block identifier q and the smart metasurface panel identifier r, and the beam index x corresponds to the smart sub-block identifier q and the metasurface panel identifier r.

Optionally, the time domain resources identified by the time domain resource identifier of each forwarding resource in at least one forwarding resource of the forwarding resource group formed according to method 4.3 at least partially overlap with each other. For example, the forwarding resource group includes forwarding resource 1 and forwarding resource 2, wherein forwarding resource 1 and forwarding resource 2 include time domain resource identifier 1. For another example, forwarding resource 1 includes time domain resource identifier 1, forwarding resource 2 includes time domain resource identifier 2, and the time domain resource identified by time domain resource identifier 1 partially overlaps with the time domain resource identified by time domain resource identifier 2.

[0125] Optionally, at least one forwarding resource group may constitute a forwarding resource set or a forwarding resource list, and the time domain resource identifiers, beam indexes, and reflection unit identifiers having corresponding relationships may form configuration information in the form of a forwarding resource set or a forwarding resource list. Optionally, the time domain resources identified by the time domain resource identifier of each forwarding resource in at least one forwarding resource in the forwarding resource set or forwarding resource list formed according to method 4.3 at least partially overlap with each other.

[0126] In one implementation, the network device may generate multiple forwarding resource groups, multiple forwarding resource sets, or multiple forwarding resource tables; the network device statically selects a forwarding resource group from multiple forwarding resource groups as configuration information, or statically selects a forwarding resource set from multiple forwarding resource sets as configuration information, or statically selects a forwarding resource table from multiple forwarding resource tables as configuration information. The network device sends configuration information to the intelligent metasurface device. Optionally, the network device also sends forwarding resource indication information to the intelligent metasurface device, and the configuration information and the forwarding resource indication information may be sent simultaneously, for example, the configuration information and the forwarding resource indication information may be carried by the same signaling to be sent simultaneously, and the configuration information and the forwarding resource indication information may be sent separately and / or at different times, for example, the forwarding resource indication information may be carried by different signaling from the configuration information to be sent separately and / or at different times. The intelligent metasurface device determines the forwarding resource to be sent from the configuration information based on the forwarding resource indication information.

[0127] In another implementation, the network device may generate multiple forwarding resource groups, multiple forwarding resource sets, or multiple forwarding resource tables; the network device semi-statically selects a forwarding resource group from multiple forwarding resource groups as configuration information, or semi-statically selects a forwarding resource set from multiple forwarding resource sets as configuration information, or semi-statically selects a forwarding resource table from multiple forwarding resource tables as configuration information. The network device sends configuration information to the intelligent super surface device. Optionally, after sending the configuration information, the network device also sends activation information or deactivation information to the intelligent super surface device. Optionally, the activation information or deactivation information is carried by a media access control control element (Media Access Control Control Element, MAC CE). The intelligent super surface device activates the forwarding resources in the configuration information according to the activation information to send beams according to the activated forwarding resources. The intelligent super surface device deactivates the forwarding resources in the configuration information according to the deactivation information to stop sending beams according to the deactivated forwarding resources.

[0128] Optionally, the intelligent metasurface device can also determine the reflection unit and / or beam used for beam transmission according to the time domain resource identifier in the configuration information, the beam index of the intelligent metasurface device, the reflection unit identifier of the intelligent metasurface device, and the correspondence between the three. Optionally, the reflection unit and / or beam used for beam transmission can be further determined in combination with the correspondence between the beam index of the intelligent metasurface device and the reflection unit identifier of the intelligent metasurface device. For example, for the configuration information generated according to method 4.1, method 4.2 and / or method 4.3, the intelligent metasurface device determines a time domain resource identifier and a beam index identifier corresponding to each reflection unit identifier according to the correspondence between the time domain resource identifier in the configuration information and the beam index of the intelligent metasurface device, the reflection unit identifier of the intelligent metasurface device, and the beam index of the intelligent metasurface device and the reflection unit identifier of the intelligent metasurface device. Optionally, the beam indexes corresponding to each determined reflection unit identifier are different or the same, and the beam identified by the beam index corresponding to each determined reflection unit identifier can be sent through the time domain resource identified by the time domain resource identifier corresponding to each reflection unit identifier. The beam identified by the same beam index can be used for transmission by the reflection units identified by multiple reflection unit identifiers. Optionally, the beams identified by the same beam index have the same width, but the beams identified by the same beam index corresponding to different reflection unit identifiers have different pointing directions.

[0129] In one implementation, there is no first reflection unit identifier in the configuration information sent by the network device, or there is a first reflection unit identifier and there is no beam index corresponding to the first reflection unit identifier. The reflection unit identified by the first reflection unit identifier is a reflection unit that the intelligent super surface device supports beam adjustment. The intelligent super surface device can freely call the first reflection unit that supports beam adjustment to send beams, and the first reflection unit is a reflection unit that is not in the configuration information and / or a reflection unit identified by a reflection identifier (such as the first reflection unit identifier) ​​that is not in the configuration information. Optionally, the first beam sent by the first reflection unit is different from the multiple beams determined according to step 402. The first beam and the multiple beams determined according to step 402 can be sent simultaneously. For example, the intelligent super surface device determines beam 1, beam 2, and beam 3 to be sent simultaneously according to step 402, and the first reflection unit uses beam 4 to send, so that the intelligent super surface device can send beam 1, beam 2, beam 3 and beam 4 at the same time.
