Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to a beam reporting method, apparatus and network-side equipment. Background Technology

[0002] In research on next-generation communication systems beyond 4G, the supported operating frequency bands will be increased to above 6GHz, reaching a maximum of approximately 100GHz. High-frequency bands have relatively abundant idle frequency resources, which can provide greater throughput for data transmission. High-frequency channel modeling has already been completed. High-frequency signals have shorter wavelengths, allowing for the placement of more antenna elements on the same panel size compared to low-frequency bands, and enabling the formation of more directional beams with narrower lobes using beamforming technology. Therefore, combining massive MIMO with high-frequency communication is also one of the future trends.

[0003] When a network deploys different base stations using different Time Division Duplex (TDD) configurations, different base stations may be in downlink (DL) transmission or uplink (UL) reception at the same time. In this case, the base station performing DL transmission will cause cross-link interference to the base station performing UL reception. When the base station uses full-duplex mode, the cross-links between adjacent base stations become even more complex. Summary of the Invention

[0027] Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network-side device 12. Terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, vehicle-mounted device (VUE), pedestrian terminal (PUE), smart home (home devices with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), game console, personal computer (PC), ATM, or self-service machine, etc. Wearable devices include: smartwatches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. It should be noted that the specific type of terminal 11 is not limited in this embodiment. Network-side equipment 12 may include access network equipment or core network equipment. Access network equipment 12 may also be referred to as radio access network equipment, radio access network (RAN), radio access network function, or radio access network unit.

The base station is not limited to specific technical terms. It should be noted that in this application embodiment, only a base station in an NR system is used as an example for description, and the specific type of base station is not limited.

[0028] The following explains some of the operations mentioned in the embodiments of this application:

[0029] For uplink beam indication, the base station indicates the beam direction adopted by the UE on the UL scheduling resources, and the beam direction is represented by the SRS resource indicator (SRI). For downlink beam indication, the base station indicates the beam direction on the DL scheduling resources so that the UE can determine its receiving beam. The downlink beam direction is indicated by the associated Transmission Configuration Indicator (TCI), where the TCI reflects information such as the CRI and SSB index.

[0030] To enable flexible network deployment, the NR system configures the transmission direction of each symbol in a time slot using a slot format.

[0031] In NR, the transmission direction of time slots is defined in three ways: downlink (DL), uplink (UL), and flexible. When a time slot or symbol is configured as DL or UL, the transmission direction at that moment is explicit; when a time slot or symbol is configured as flexible, the transmission direction at that moment is undetermined. The network can modify the transmission direction of flexible time slots or symbols through dynamic signaling, such as dynamic slot format indicator (dynamic SFI).

[0032] A slot can contain downlink, uplink, and flexible OFDM symbols; the flexible symbol can be rewritten as a downlink or uplink symbol.

[0033] SFI can indicate the format of one or more slots.

[0034] SFI can flexibly change the format of the slot according to the needs of business transmission.

[0035] The UE decides whether to monitor the PDCCH based on the instructions from the SFI.

[0036] The Rel-18 features flexible / full duplex operation on the network side and half-duplex operation on the user / terminal side.

[0037] For the symmetrical spectrum of Frequency Division Duplexing (FDD): the uplink or downlink spectrum of FDD: can be semi-statically configured or dynamically indicated as downlink or uplink transmission on certain time slots / symbols.

[0038] For the asymmetric spectrum of Time Division Duplexing (TDD): different frequency domain resources on certain time slots / symbols of TDD can be configured semi-statically or dynamically indicated to have both uplink transmission and downlink reception.

[0039] For half-duplex terminals, only uplink transmission or downlink reception can be performed at the same time; that is, the terminal cannot both receive and transmit signals at the same time.

[0040] The beam reporting method, apparatus, and network-side equipment provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0041] like Figure 2 As shown, this application provides a beam reporting method, including:

[0045] Optionally, the aforementioned second network-side device can be one network device or multiple network devices. That is, multiple network devices send beamforming report configuration information to the first network-side device, and the first network-side device reports reports to its corresponding network devices.

[0046] Optionally, the frequency domain subband can be understood as a resource block (RB), subband, or bandwidth part (BWP).

[0047] It should be noted that the "time domain resources", "frequency domain sub-band", "frequency domain resources", etc. mentioned in the embodiments of this application can specifically be flexible resources or full duplex resources.

[0073] It should be noted that the beam report configuration information mentioned in the embodiments of this application can be carried in the cell configuration information or the frequency domain sub-band configuration information; for example, if the beam report configuration information includes the reference signal resource information of the cell, then the beam report configuration information is carried in the cell configuration information; as another example, if the beam report configuration information includes the reference signal resource information on the frequency domain sub-band, then the beam report configuration information is carried in the frequency domain sub-band configuration information.

[0088] Optionally, the aforementioned beamlink quality includes the beamlink's Layer 1 Reference Signal Receiving Power (L1-RSRP), Layer 1 Signal to Interference plus Noise Ratio (L1-SINR), throughput, etc.

[0089] It should be noted that the beam identifiers in the N groups of beam identifiers are arranged in a preset order. The beam identifiers are determined according to the preset order, such as ascending or descending order of beam link quality; or according to the corresponding cell or frequency domain sub-band number; or according to the ID corresponding to the beam identifier group, in ascending or descending order.

[0090] As another optional embodiment, the non-group-based beam reporting also includes at least one of the following:

[0091] The beam link quality corresponding to each of the P beam identifiers;

[0092] The second indication information corresponding to each of the P beam identifiers is used to identify the received beam information corresponding to each beam identifier; for example, the second indication information is the received beam ID.

[0095] In at least one embodiment of this application, a set of beam identifiers corresponds to reference signal resources of one or more cells, and / or, a set of beam identifiers corresponds to reference signal resources of one or more frequency domain subbands.

[0096] For example, when a set of beam identifiers includes one beam identifier, the set of beam identifiers corresponds to the reference signal resources of one cell or one frequency domain sub-band; as another example, when a set of beam identifiers includes multiple beam identifiers, the set of beam identifiers corresponds to the reference signal resources of multiple cells or multiple frequency domain sub-bands.

[0108] The aforementioned differential method can be used to indicate the beam link quality corresponding to the beam identifiers of multiple beams in the same cell or the same frequency domain sub-band. For example, beam 1 (reference beam) is the absolute value of the link quality, and the other beams are the relative values ​​of the beam link quality. It can also be used to indicate the beam link quality corresponding to the beam identifiers of multiple beams in multiple cells or multiple frequency domain sub-bands. The beam of cell 1 or sub-band 1 (reference beam) is the absolute value of the link quality, and the beams of other cells or sub-bands are the relative values ​​of the beam link quality.

The first network-side device sends at least one beam report corresponding to a cell and / or at least one beam report corresponding to a frequency domain sub-band to the second network-side device according to the beam report configuration information. This enables the network-side device to understand the beam status of different cells or different frequency domain sub-bands in a timely manner, and reduces the impact of interference between network-side devices through beam coordination, thereby ensuring transmission performance.
