Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, and in particular to a data processing method, device, node and storage medium. BACKGROUND

[0002] In the Rel-15 NR specification, flexible spatial scanning freedom can be supported, which scans the three-dimensional space based on the synchronization signal and physical broadcast channel resource block (SS / PBCH blocks, SSB) time division. For example, in a general operator networking scheme, a single wide beam can be used to achieve full cell coverage, or multiple SSB horizontal narrow beam combinations can be used to quickly achieve high-quality coverage and network performance. However, in the first networking mode, due to the loss of the wide beam form gain and the weak anti-interference ability, the coverage range is limited to a certain extent; the second networking mode has poor scalability and limited vertical coverage. If the vertical coverage is to be expanded, the number of horizontal beams needs to be reduced to weaken the horizontal coverage performance. Moreover, to adapt to the changing environment, horizontal-vertical linkage adjustment and optimization need to be performed frequently, which increases the difficulty of network optimization. At the same time, too many beams increase the number of System Information Block (SIBs) and Paging message (Paging) rotation, resulting in large air interface resource and power consumption overhead.

[0024] To make the objects, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other as long as there is no conflict.

[0025] In addition, in the embodiments of the present application, the words such as "optionally" or "exemplarily" are used to mean as an example, illustration or description. Any embodiment or design scheme described as "optionally" or "exemplarily" in the embodiments of the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. In fact, the words such as "optionally" or "exemplarily" are used to present the related concepts in a specific way.

[0026] In order to facilitate the understanding of the scheme provided by the embodiments of the present application, some descriptions of concepts related to the present application are exemplarily given for reference. As shown below:

[0027] SSB: Synchronization Signal and Physical Broadcast Channel Resource Block, used for cell search, synchronization, channel measurement and beam management, mainly including Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS) and Master Information Block (MIB).

[0028] SIB: System Information Block, including first system message (SIB1) and other system messages (Other System Information, OSI), mainly used for issuing cell wireless resource public configuration, cell reselection, earthquake and tsunami warning, etc.

[0029] Paging: Paging message, used to inform User Equipment (UE) of system message change or to inform UE to access the network.

[0030] PDSCH (Physical downlink shared channel): Physical downlink shared channel, used for transmitting data service.

[0031] PDCCH (Physical downlink control channel): The physical downlink control channel is used to send scheduling control information.

[0032] Based on the above concepts, embodiments of this application provide a data processing method, such as... Figure 1 As shown, the method includes the following steps:

[0033] S101, The communication node obtains the configuration information of the neighboring cell.

[0034] For example, the configuration information in the embodiments of this application may include m horizontal beams staggered in the time domain and n vertical beams, where m and n are both integers greater than 0.

[0035] In this embodiment of the application, the communication node can be selected as a base station. That is, this step can be understood as the base station obtaining the beam configuration information of the neighboring cells in the horizontal and vertical directions.

[0036] S102. The communication node sends the service data of this cell according to the configuration information.

[0037] After obtaining the beam configuration information of neighboring cells in the horizontal and vertical directions, the communication node can send service data related to its own cell based on this configuration information. For example, the communication node can send service data on the PDSCH by adjusting rate matching and limiting scheduling based on the configuration information of neighboring cells.

[0038] Since the horizontal beams in the configuration information of adjacent cells are staggered in the time domain, the number of cell beams can be reduced. Furthermore, when communication nodes send service data based on the configuration information of adjacent cells, mutual interference between neighboring cells can also be reduced.

[0039] This application provides a data processing method in which a communication node obtains configuration information of neighboring cells. The configuration information includes m horizontal beams staggered in the time domain and n vertical beams, where m and n are both integers greater than 0. The communication node then transmits its own cell's service data according to the configuration information. This staggered horizontal beam configuration in the time domain not only reduces the number of cell beams and lowers air interface resource overhead, but also reduces mutual interference between neighboring cells when transmitting service data based on this configuration information. Furthermore, this horizontal-vertical beam configuration reduces the difficulty of network planning and optimization, and improves the flexibility of network deployment.

[0040] In one embodiment, the horizontal beam configured in the above scheme can be a wide beam, and the vertical beam can be a wide beam and / or a narrow beam. That is, using a wide beam to provide basic road surface coverage in the horizontal direction can reduce the number of beams used in a cell, and staggering the wide beams in the temporal domain can reduce mutual interference between neighboring cells. In the vertical direction, wide beams and / or narrow beams can be flexibly selected according to coverage requirements. For example, in a large-area, densely built-up coverage scenario, multiple wide beams can be configured with different downtilt angles to achieve vertical coverage; in a scenario with lower building density, multiple narrow beams can be configured to achieve vertical coverage. Of course, wide beams and narrow beams can also be deployed simultaneously in the vertical direction according to actual coverage needs.

[0041] It should be noted that, given sufficient time-domain location, the aforementioned vertical beams can also be configured with staggered time-domain locations, which can reduce interference between adjacent cells in the vertical beam direction.

[0042] In one embodiment, the acquisition of configuration information of neighboring cells by the communication node in step S101 can be implemented simultaneously in the following optional ways. For example, if the communication node has configuration information for all neighboring cells and its own cell configured, the communication node can directly obtain the configuration information of the corresponding neighboring cells from its own stored configuration information. If the communication node only has configuration information for its own cell configured, the communication node can communicate with the communication nodes of neighboring cells through the inter-cell communication interface to obtain the configuration information of neighboring cells.

[0043] In one embodiment, the method of sending the service data of this cell according to the configuration information in step S102 above may include, but is not limited to, the following implementation methods.

[0044] For example, if the configuration information is the SSB location of a neighboring cell, the communication node can send its own cell-related service data from a location other than the SSB location of the neighboring cell. Alternatively, if the configuration information is the SIBs location or Paging transmission location of a neighboring cell, the communication node can send its own cell-related service data from a location other than the SIBs location or Paging transmission location of the neighboring cell. In other words, when sending its own cell's service data, the communication node can avoid the SSB locations, SIBs locations, or Paging transmission locations of neighboring cells, thereby reducing interference between neighboring cells.

[0045] In this embodiment of the application, configuring a wide beam in the horizontal direction allows for higher transmission power to improve beam coverage performance. At the same time, since the number of cell beams is reduced, the number of times communication nodes send SSB / SI / Paging signals can be reduced. Compared with narrow beam networking, this can save a lot of system resource overhead and power consumption.

[0046] The implementation process of the above scheme will be further described below with a specific example. For example, a low-frequency 8SSB beam will be used as an example.

[0047] like Figure 2 As shown, assuming a wide beam is configured to provide basic horizontal coverage, then in the horizontal direction, the wide beams can be staggered using a Physical Cell Identifier (PCI) modulo 5 configuration. The wide beams of different cells are configured in different time domains, and the horizontal wide beams between adjacent cells do not interfere with each other. A maximum of three beams can be configured in the vertical direction, such as... Figure 2 As shown, only one wide beam is configured for interfering cell 4 in the vertical direction, while wide and narrow beams can be configured simultaneously for interfering cells 1-3. In this embodiment, a beam with a larger angle in the vertical direction can be understood as a wide beam, and a beam with a smaller angle can be understood as a narrow beam.

[0048] In this way, after obtaining the configuration information of each of the adjacent cells, the communication node can avoid the time-frequency domain position specified by the configuration information of the adjacent cells, and send service data in the cell in a way that restricts scheduling, rate matching and other methods.

[0049] like Figure 3 As shown, if the above configuration information represents the SSB location of each cell, then after obtaining the configuration information of neighboring cells, the communication node can obtain the SSB location of the neighboring cells, and then mark the SSB location of the neighboring cells, for example, as... Figure 3 As shown, a marker 1 can be set at the SSB location of adjacent cells, thereby enabling service data transmission at time-frequency domain locations other than marker 1. If the above configuration information refers to the SIB locations of each cell or the transmission location of Paging, then the communication node can proceed as follows: Figure 4 The method shown marks the SIBs locations or Paging transmission locations of adjacent cells as mark 2, and performs service data transmission at PDSCH time-frequency domain locations other than mark 2. Optionally, as... Figure 5As shown, assume two wide beams are used to provide basic horizontal coverage. For example, the two wide beams have different horizontal downtilt angles; one wide beam is used for near-point horizontal coverage, and the other is used for far-point horizontal coverage. The wide beams are staggered in the horizontal direction using cell PCI mode 3. A maximum of two beams are configured in the vertical direction; for example, the serving cell and interfering cell 1 are configured with two narrow beams, and interfering cell 2 is configured with one wide beam.

[0050] Based on this configuration method, after the communication node obtains this configuration information, if the configuration information is about the SSB location, then... Figure 6 As shown, communication nodes can be... Figure 6 The method shown sets a marker 1 at the SSB location of adjacent cells and transmits service data at time-frequency domain locations other than the adjacent cell SSB location (i.e., the marker 1 location). If the above configuration information pertains to the SIB locations of each cell or the transmission location of paging, then the communication node can... Figure 7 The method shown sets the location of the adjacent cell SIBs or the transmission location of the Paging to mark 2, and then transmits service data at the PDSCH time-frequency domain location other than the location of the adjacent cell SIBs or the transmission location of the Paging (i.e., mark 2 location).

[0051] It should be noted that, in Figure 4 , Figure 7 At the PDCCH position marked in the middle, the communication node can send scheduling control information.

[0052] The above configuration method effectively reduces the number of beams required for network deployment, while also reducing the number of SSB / SI / Paging beam rounds, thereby saving air interface resource overhead. Furthermore, it can increase service capacity under high load and reduce device power consumption under low load. Moreover, since the configuration information of neighboring cells is obtained, when sending service data within the local cell, corresponding locations can be avoided, reducing data interference between cells.

[0053] Compared with the existing technology of eight narrow beam coverage schemes, the solution provided in this application embodiment can improve the coverage range by 3-5dB, save more than 5% of physical resources, and save more than 10% of power consumption under light load.

[0057] The communication module is used to send service data of this cell according to the configuration information.

[0058] For example, the horizontal beam is a wide beam, and the vertical beam is a wide beam and / or a narrow beam.

[0059] In one embodiment, the acquisition module described above can be used to acquire configuration information of neighboring cells from the configuration information stored in the device.

[0060] Alternatively, it can communicate with the communication nodes of neighboring cells through a communication interface to obtain the configuration information of neighboring cells.

[0061] In one embodiment, when the configuration information is the SSB location of a neighboring cell, the communication module can transmit the service data of its own cell from a location other than the SSB location of the neighboring cell. When the configuration information is the SIB location of a neighboring cell or the transmission location of Paging, the communication module can transmit the service data of its own cell from a location other than the SIB location of the neighboring cell or the transmission location of Paging.
