RIS introduction:

FIG. 3 illustrates a logical structure of an RIS node, wherein an RIS-MT is used for the RIS node to establish a wireless connection with a base station (gNB), and the RIS node sends measurement reports of the RIS node, reflection control signaling of the RIS node from the base station, and the like; the RIS-RSU is used for carrying out reflection transmission of signals between the base station and the UE, and comprises a synchronous signal block (Synchronization signal Block, SSB), a system message, uplink and downlink special signaling, an uplink and downlink control channel, an uplink and downlink data channel and the like; the RIS-MT may use separate antennas, or may share an antenna (or a wireless signal receiving medium) on the RIS-RSU, and an RIS-RSU control unit (for example, a panel controller) is provided between the RIS-MT and the RIS-RSU, and the RIS-MT sends a received RIS-RSU control command to the RIS-RSU control unit, where the RIS-RSU control unit controls the RIS-RSU. The base station may control the transmission parameters of the RIS-RSU, including the reflected beam parameters, by sending signaling to the RIS-MT for controlling the RIS-RSU. The RIS-RSU unit of the RIS node is a passive radio signal reflection panel and comprises a reflection array formed by a plurality of reflection units, and the base station can achieve the purpose of controlling the reflection beam of the RIS-RSU by configuring a phase amplitude matrix of the reflection array.

NCR introduction:

The NCR node may receive control from an upstream base station, i.e., the base station may control the transmit parameters of the smart amplifier, such as the switching of the NCR node and the transmit beam, to improve the efficiency of the amplifier and reduce interference. As shown in fig. 4, the network structure includes a base station, an NCR node, and a UE, where the NCR node includes a terminal (mobile termination) (i.e., NCR-MT) and a Relay Unit (RU) (i.e., NCR-RU). The NCR-MT can establish connection with an upstream base station, and the base station can instruct the transmission/reception related parameters of the NCR-MT/NCR-RU of the signal amplifier, including power control parameters, beam parameters, switching parameters and the like, by the interaction control signaling of the NCR-MT and the signal amplifier.

The data forwarding method and forwarding configuration method provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

Referring to fig. 5, fig. 5 is a flowchart of a data forwarding method provided in an embodiment of the present application, where the method may be performed by a forwarding node, as shown in fig. 5, and includes the following steps:

step 501, when a forwarding node establishes a wireless connection with a first cell, receiving first shared configuration information from a first CU, where the first CU is a CU to which the first cell belongs, and the first shared configuration information is used to configure the forwarding node to forward data for a second cell, where the second cell is a neighboring cell of the first cell.

In this embodiment, the forwarding node may be a device that may implement cell coverage expansion or enhancement, including, but not limited to, an RIS node or an NCR node. The first cell may be any cell, the second cell may include neighboring cells of one or more first cells, wherein the second cell and the first cell may belong to the same Distributed Unit (DU), or the second cell and the first cell may belong to different DUs. In addition, the DU to which the second cell belongs and the DU to which the first cell belongs may belong to the same CU, that is, the second cell and the first cell belong to the same CU; or the DU to which the second cell belongs and the DU to which the first cell belongs may belong to different CUs, that is, the second cell and the first cell belong to different CUs.

The second cell may be a cell selected by the first CU, or may be a cell selected by another node, which is not limited in this embodiment.

The first shared configuration information may be used to configure a forwarding node to forward data for a second cell, and for example, the first shared configuration information may include at least one of configuration information of a first control link (control link) between the forwarding node and the second cell, configuration information of a first BackHaul link (BackHaul link) between the forwarding node and the second cell, and configuration information of a first access link (access link) between the forwarding node and a first terminal device (i.e., a terminal device served by the second cell).

Specifically, the forwarding node establishes a wireless connection with the first cell, which may include, but is not limited to, establishing a control link (control link) and a BackHaul link (BackHaul link) between the forwarding node and the first cell. In case the forwarding node establishes a wireless connection with the first cell, the forwarding node may forward data for the first cell. In some alternative embodiments, the forwarding node may use all resources of the forwarding node for forwarding data in the first cell when the forwarding node establishes a wireless connection with only the first cell, and allocate the resources of the forwarding node between the first cell and the second cell when receiving a request for forwarding data in the second cell. In some alternative embodiments, in the case that the forwarding node supports sharing by multiple cells, the forwarding node may use only part of the resources of the forwarding node to forward data for the first cell and reserve part of the resources to forward data for other cells in the case that the forwarding node establishes a wireless connection with only the first cell, and use the reserved resources for forwarding data for the second cell in the case that the requirement of forwarding data for the second cell is received.

Step 502, the forwarding node performs configuration according to the first shared configuration information.

For example, the forwarding node may perform a related configuration of sharing according to the first shared configuration information, e.g. establish a wireless connection of the forwarding node with the second cell, so that the forwarding node may be shared by the first cell and the second cell.

Step 503, when the configuration is completed, the forwarding node forwards data for the first cell and the second cell respectively.

In this step, the forwarding node operates in a shared mode in case the configuration is completed, in which case the forwarding node may forward data for the first cell and the second cell, respectively.

According to the data forwarding method provided by the embodiment of the application, under the condition that wireless connection is established between a forwarding node and a first cell, first shared configuration information is received from a first CU, wherein the first CU is the CU to which the first cell belongs, the first shared configuration information is used for configuring the forwarding node to forward data for a second cell, and the second cell is a neighboring cell of the first cell; the forwarding node performs configuration according to the first shared configuration information; and under the condition that the configuration is completed, the forwarding node forwards data for the first cell and the second cell respectively. Namely, when the forwarding node forwards data for the first cell, the forwarding node is configured to be shared by the first cell and the second cell, so that the forwarding node can forward data for the first cell and the second cell respectively, that is to say, the coverage areas of the first cell and the second cell can be expanded through one forwarding node, and further, the cost can be saved while the coverage area of the cells is expanded.

Optionally, before the forwarding node forwards data for the first cell and the second cell, the method further includes:

the forwarding node receives second shared configuration information from the first CU, wherein the second shared configuration information is used for configuring the forwarding node to forward data for the first cell;

and the forwarding node executes configuration according to the second shared configuration information.

In this embodiment, the second shared configuration information may include, but is not limited to, at least one of configuration information of a second control link (control link) between the forwarding node and the first cell, configuration information of a second BackHaul link (BackHaul link) between the forwarding node and the first cell, and configuration information of a second access link (access link) between the forwarding node and a second terminal device (i.e., a terminal device served by the first cell).

In some alternative embodiments, the configuration information of the second control link includes at least one of: radio resource configuration information of the second control link; and/or

The configuration information of the second backhaul link includes at least one of: forwarding power configuration information of the second backhaul link, beam configuration information of the second backhaul link, forwarding time window configuration information corresponding to the second backhaul link, and processing delay information of side control information corresponding to the second backhaul link; and/or

The configuration information of the second access link includes at least one of: the forwarding power configuration information of the second access link, the beam configuration information of the second access link, the forwarding time window configuration information corresponding to the second access link, and the processing delay information of the side control information corresponding to the second access link.

The radio resource configuration information of the second control link may include, but is not limited to, one or more of a control resource set (Control Resource Set, core) configuration and a physical downlink control channel (Physical Downlink Control Channel, PDCCH) timing (occalasion) configuration of the second control link, a power configuration and a beam configuration of a broadcast signal and a system message that the forwarding node forwards the first cell, and so on.

For example, the forwarding node may reconfigure a wireless connection between the forwarding node and the first cell according to the second shared configuration information, e.g., the forwarding node may reconfigure a control link, a backhaul link, etc. between the forwarding node and the first cell according to the second shared configuration information.

In some alternative embodiments, the forwarding node may use all resources of the forwarding node for forwarding data for the first cell in case a wireless connection is established with the first cell only; under the condition that the second cell needs to use the forwarding node to forward data, resources of the forwarding node can be distributed between the first cell and the second cell, specifically, the forwarding node can receive the first shared configuration information and the second shared configuration information from the first CU, perform configuration related to the second cell according to the first shared configuration information, perform configuration related to the first cell according to the second shared configuration information, and realize sharing of the forwarding node between the first cell and the second cell.

It should be noted that, the first shared configuration information and the second shared configuration information may be configured reasonably according to requirements of the first cell and the second cell. In addition, the first shared configuration information and the second shared configuration information may be sent to the forwarding node through the same message, or may be sent to the forwarding node through different messages, which is not limited in this embodiment.

In the embodiment of the application, if the forwarding node is used for forwarding data in the first cell, if the second cell needs to use the forwarding node for forwarding data, the forwarding node receives the first shared configuration information and the second shared configuration information from the first CU, performs configuration related to the second cell according to the first shared configuration information, performs configuration related to the first cell according to the second shared configuration information, and realizes sharing of the forwarding node between the first cell and the second cell, so that flexibility of sharing the forwarding node between the cells can be improved while sharing the forwarding node between the cells is ensured.
