Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

The technical solution provided by the present invention can be applied to various communication systems, for example, a 5G communication system, a future evolution system, or a variety of communication convergence systems, and so on. It can include a variety of application scenarios, such as Machine to Machine (M2M), D2M, macro and micro communications, enhanced Mobile Broadband (eMBB), ultra-high reliability and ultra-low latency communications (ultra Scenarios such as Reliable&Low Latency Communication (uRLLC) and Massive Machine Type Communication (mMTC).

FIG. 1 shows a schematic diagram of a possible structure of a communication system involved in an embodiment of the present invention. As shown in Figure 1, the communication system is an integrated access backhaul (IAB) system, and the IAB system includes: at least one IAB node device 100 and at least one user equipment (User Equipment, UE) 200, and an IAB control node device 300.

Among them, an IAB node device 100 includes a distributed unit (Distributed Unit, DU) functional part and a mobile terminal unit (Mobile Termination, MT). The aforementioned at least one IAB node device 100 includes a parent IAB node device and one or more child IAB node devices corresponding to the parent IAB node device. If the aforementioned IAB control node device 300 is equipped with a control plane (control plane) unit/control plane protocol stack, the node device may be called a centralized control unit (CU).

Exemplarily, relying on MT, an IAB node device can find an upstream access point (parent IAB node) and establish a wireless connection with the DU of the upstream access point. This wireless connection is called a backhaul link (backhaul link). ). After an IAB node device establishes a complete backhaul link, the IAB node device turns on its DU function, and the DU will provide cell services, that is, the DU can provide access services for the UE. A self-backhaul loop includes a donor IAB node device, and the donor IAB node device has a wired transmission network directly connected.

Figure 2 shows a schematic structural diagram of the CU-DU architecture of the IAB system involved in an embodiment of the present invention. As shown in Figure 2, in a self-backhaul loop, the DU in each IAB node device (hereinafter referred to as IAB-DU) will be connected to the IAB control node device, and the MT in the IAB node device (hereinafter referred to as IAB-DU) -MT) will also be connected to the IAB control node device. Generally, donor IAB node equipment does not have MT. Exemplarily, the IAB control node device mainly configures the DU in the IAB node device through the F1-AP protocol. The IAB control node device configures the MT in the IAB node device through the RRC protocol.

In the embodiment of the present invention, the duplexing mode between the DU and the MT of the IAB node device is divided into: half duplex and full duplex. In the case of full duplex, the DU or MT of the IAB node device can transmit and receive at the same time. Therefore, in the multiplexing mode of FDM or SDM, the IAB node equipment has the following transmission and reception modes of DU and MT:

DU and MT simultaneous transmission (DU-TX & MT-TX) mode, or DU is configured as DL and MT is configured as UL;

DU reception and MT reception (DU-RX&MT-RX) mode, or DU is configured as UL and MT is configured as DL;

DU transmission and MT reception (DU-TX&MT-RX) mode, or DU is configured as DL and MT is configured as DL;

DU reception and MT transmission (DU-RX & MT-TX) mode, or DU is configured as UL and MT is configured as UL.

In the embodiment of the present invention, the DU transmission mode is abbreviated as DU-TX, the MT transmission mode is abbreviated as MT-TX, the DU reception mode is abbreviated as DU-RX, and the MT reception mode is abbreviated as MT-RX.

In the embodiment of the present invention, as shown in FIG. 3, the interference situation of the DU and MT of the IAB node device includes at least the following scenarios:

For scenario 1 (case 1), when IAB-DU transmission and IAB-MT reception are performed at the same time, IAB-DU transmission will cause interference to IAB-MT reception, especially when IAB-DU and IAB-MT share time-frequency resources Time (ie FDM/SDM multiplexing mode).

For scenario 2 (case 2), when IAB-DU reception and IAB-MT transmission are performed at the same time, IAB-MT transmission will cause interference to IAB-DU reception, especially when IAB-DU and IAB-MT share time-frequency resources Time (ie FDM/SDM multiplexing mode).

For scenario 3 (case 3), when IAB-DU reception and IAB-MT reception are performed at the same time, the transmission signal sent to IAB-DU will also leak to IAB-MT, causing IAB-MT reception interference, and vice versa , Especially when IAB-DU and IAB-MT share time-frequency resources (ie FDM/SDM multiplexing mode).

In related technologies, for LTE and NR interference processing solutions, the base station can rely on the interference situation reported by the UE to assist it in scheduling or selecting appropriate transmission parameters. The base station will configure channel measurement reference signals and interference measurement resources for the UE, and the UE will estimate the CQI based on the measurement result, and then report it to the base station.

In NR, in the information element (informatin element) of CSI-ReportConfig, the resourcesForChannelMeasurement field is configured for the reference signal used for channel measurement, and the csi-IM-ResourcesForInterference field and/or nzp-CSI-RS-ResourcesForInterference field is configured for interference measurement. resource.

If only the resourcesForChannelMeasurement field is configured in the signaling, then the reference signal measurement is only used for L1-RSRP reporting. If the resourcesForChannelMeasurement field and the csi-IM-ResourcesForInterference field and/or the nzp-CSI-RS-ResourcesForInterference field are configured in the signaling, the measurement can be performed according to the configuration information, and the CQI can be calculated and reported.

In the embodiment of the present invention, when the IAB node reports the CQI, it can report with reference to the above described process, which is not limited in the embodiment of the present invention.

In the uplink power control process of LTE and NR, the base station configures the P0 and alpha values for the UE. The transmit power of the UE is expressed as min(Pcmax, P0+alpha*Pathloss+b), and b is other parameters that are not related to P0/alpha , Pcmax is the maximum transmit power threshold of the UE.

For interference measurement/reporting, if IAB-MT uses traditional interference measurement and CQI reporting to assist the parent IAB node in scheduling, the measurement and reporting results cannot fully reflect the interference of IAB-DU to IAB-MT. For example, on the interference measurement resource configured by the parent IAB node for the IAB-MT, the IAB-DU is not transmitted or sent at this time. Then, the result of interference measurement cannot reflect the interference of IAB-DU to IAB-MT.

To solve this problem, in the technical solution provided by the embodiment of the present invention, the IAB node device obtains the interference information of the DU of the IAB node device to the MT of the IAB node through measurement, and/or the MT of the IAB node to the DU of the IAB node And report the interference information to the target node device (that is, the parent node device of the IAB node device or the IAB control node device). Since the above interference information can reflect the actual interference between the DU and MT in the IAB node device, the target node device can adjust the DU or MT in the IAB node device based on the interference information after acquiring the above interference information. Transmit power/transmission parameters to alleviate the impact of interference.

For power control, in view of the strong interference of DU-TX to MT-RX, the transmission power of the DU cannot be completely determined independently, but there is currently no suitable solution to control the transmission power of the DU. In addition, in view of the strong interference of MT-TX to DU-RX, a more suitable uplink power control method is also needed to suppress the interference.

To solve this problem, in the technical solution provided by the embodiment of the present invention, the IAB node device obtains the target power control parameter of the target unit in the IAB node device at the target time, and then adjusts the IAB node device based on the target power control parameter. The transmit power of the target unit (that is, the MT or DU in the IAB node device) at the target time. In this way, by controlling the transmission power of the DU or MT in the IAB node device, the interference between the DU and the MT in the IAB node device can be fully suppressed, and the influence caused by the interference can be alleviated.
