[0063] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0064] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0065] First, some nouns or terms that appear in the description of the embodiments of the present application are subject to the following interpretations:

[0066]

[0067] In a wireless network, the "channel bandwidth = maximum transmission bandwidth + protection bands on both sides" of a cell; where the "maximum transmission bandwidth" is measured in resource blocks (RBs), and the protection band is measured in kHz. Figure 2As shown. The 5G NR network specifies two frequency ranges: FR1 band and FR2 band. The frequency range of FR1 is 450MHz~6GHz, also known as Sub-6GHz band; the frequency range of FR2 band is 24.25GHz~52.6GHz, commonly known as millimeter wave. Their maximum bandwidth and subcarrier spacing are different according to the range: the maximum bandwidth in sub 6GHz is 100MHz; the maximum bandwidth in millimeter wave is 400MHz. Among them:

[0068] Subcarrier spacing of 15 and 30 KHz can only be used in Sub 6 GHz; subcarrier spacing of 120 and 240 KHz can only be used in millimeter waves; subcarrier spacing of 60 KHz can be used in both sub 6 GHz and millimeter waves.

[0069] like Figure 3 As shown in the figure, the NR synchronization block (SSB) includes PSS, SSS and PBCH. One SSB consists of three parts: PSS, SSS and PBCH. PSS, SSS and PBCH adopt TDM method: one SSB occupies 4 OFDM symbols, of which PSS and SSS each occupy one symbol, and PBCH occupies two symbols, in the order of PSS-PBCH-SSS-PBCH. The advantage of placing SSS in the middle of PBCH symbol is that SSS can be used to assist PBCH demodulation. The bandwidth of one SSB is 20 PRBs (Physical Resource Block), of which the bandwidth of PSS and SSS is 12 PRBs, and the bandwidth of PBCH is 20 PRBs. The center frequency of PSS / SSS is aligned with the center frequency of PBCH. In addition, PBCH also occupies part of the PRBs of the OFDM symbol where SSS is located. PSS, SSS and PBCH in each SSB use the same subcarrier spacing.

[0070] NR bandwidth is very large. In order to save power consumption and improve resource utilization, UE supports partial bandwidth (BWP) configuration. BWP includes initial BWP, activated BWP and default BWP, among which initial BWP includes initial uplink and downlink BWP. Initial DL BWP and initial UL BWP will be configured in SIB1. If initial BWP is not configured, CORESET0 is the default initial BWP, where CORESET (control-resource set) is a set of physical resources (i.e. a specific area on the NR downlink resource grid) used to carry PDCCH (physical downlink control channel) / DCI (downlink control information) parameters. Initial BWP is mainly used for the initial access process, such as the reception of SIB1, the reception of RAR and Msg4 during the random access process, and the transmission of preamble and Msg4.

[0071] During the initial access process, the UE first synchronizes with the cell by searching for PSS / SSS signals, and then receives the cell MIB (Master Information Block) message after time synchronization. Through this message, the time-frequency position information of CORESET#0 can be obtained, and DCI (downlink control information) (SIB) (System Information Block) can be monitored in CORESET#0 to obtain SIB1 messages, where SIB (System Information Block) is the system information block. Decode SIB1 to obtain the initial downlink / uplink BWP and CORESET information for RAR / msg4 DCI. However, there are two situations:

[0072] case#1: If there is no initial DL BWP in SIB1, CORESET#0 is used as the initial DL BWP for random access;

[0073] case#2: If there is no configuration information of CORESET for RAR / msg4 DCI in SIB1, CORESET#0 is used to carry DCI for RAR / msg4. NG-RAN consists of 5G base stations (gNB) and evolved LTE base stations (ng-eNB). In a distributed architecture, gNB has complete protocol stack functions; in a centralized architecture, gNB is separated into gNB-CU (gNB Central Unit) nodes and gNB-DU (gNB Distributed Unit) nodes. In a centralized architecture, gNB can be composed of one gNB-CU and multiple gNB-DUs. gNB-CU and gNB-DU implement different protocol stack functions respectively. From the perspective of other NG-RAN nodes and 5GC, gNB-CU and gNB-DU are one gNB node. gNB-CU and gNB-DU are connected through the F1 interface, and one gNB-DU can only be connected to one gNB-CU.

[0074] To achieve large connections, high capacity, ultra-reliable and low-latency communications, 5G networks use multi-TRP (Transmit / Receive Point) transmission access point technology to improve high reliability, large range and high capacity network performance through flexible deployment scenarios. In multi-TRP applications, the serving cell can schedule resources from two TRP units for a single terminal, such as Figure 3 As shown, this provides better coverage, reliability and data rate for PDSCH, PDCCH, PUSCH and PUCCH.

[0075] GSCN (Global Synchronization Channel Number): When searching for a cell when the terminal is just turned on, it can only detect SSB signals based on the frequency bands supported by the operator and the terminal to perform downlink time and frequency synchronization. Due to the small granularity of the global frequency grid, the value range of NR-ARFCN is large. If blind detection is performed directly based on the global frequency grid, the synchronization delay will be relatively large. In order to effectively reduce the synchronization delay of this process, 3GPP specifically defines the synchronization grid and limits the search range through the global synchronization channel number (GSCN).

[0076] The minimum channel bandwidth currently supported by 5G NR is 5MHz. With the growing demand for dedicated spectrum with available bandwidth less than 5MHz, the existing standards need to be enhanced to support channel bandwidth less than 5MHz. In order to support available bandwidth less than 5MHz, the following problems still exist in the target standards and implementation:

[0077] The current standard cannot support transmission bandwidth configurations less than 5MHz: The minimum channel bandwidth supported in the current protocol is 5MHz. When the subcarrier is 15kHz, the corresponding number of transmission channel wireless resource blocks is 25. The current standard cannot support channel bandwidth and / or transmission bandwidth configurations less than 5MHz, cannot support a smaller number of wireless resource blocks, and cannot provide more flexible support;

[0078] At present, the base station separation architecture cannot support channel bandwidth configuration less than 5MHz between CU and DU: According to the current protocol, the separation entity DU cannot send the transmission bandwidth configuration less than 5MHz to the centralized entity through the F1 interface, and cannot provide more flexible support for the terminal;

[0079] The current standard cannot support SRS configuration for transmission bandwidth below 5MHz: According to the current protocol, the separated entity DU cannot send the SRS configuration for transmission bandwidth below 5MHz to the centralized entity CU through the F1 interface. Therefore, it is impossible to provide the terminal with relevant SRS configuration to provide better support;

[0080] The current standard cannot configure a transmission bandwidth configuration of less than 5 MHz for a terminal: In the current protocol, a base station cannot send a transmission bandwidth configuration of less than 5 MHz to a terminal through an RRC message, and cannot issue a more flexible configuration to the terminal to provide better services.

[0081] Based on the above requirements and reason analysis, the current 3GPP 5G protocol cannot meet the requirements and needs to be enhanced in new ways to better support flexible transmission bandwidth configuration.

[0082] In order to support transmission bandwidth below 5MHz, this patent proposes a small bandwidth wireless resource configuration method, where small bandwidth can refer to transmission bandwidth below 5MHz. Through this method, the base station separation entity can generate relevant configurations for transmission bandwidth below 5MHz, including relevant configurations such as the number of wireless resource blocks and detection reference signals. Subsequently, the base station separation entity sends the generated resource configuration for less than 5MHz to the base station centralized entity. Finally, the base station centralized entity sends the relevant configurations for transmission bandwidth below 5MHz to the terminal through an RRC message to better support terminal performance.

[0083] Figure 1 1 is a flow chart of a wireless resource configuration method 1 according to an embodiment of the present invention. The wireless resource configuration method 1 can be applied to a base station. The base station can include a base station centralized entity and a base station separated entity.
