[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on and claims priority to an application filed in China with application number 202311048261.6 and filing date August 18, 2023. The disclosure of the application in China is hereby incorporated as a whole into this application. Technical Field

[0003] The present application relates to the field of wireless communications, and in particular to a method and apparatus for configuring extended resources. Background Art

[0004] In order to meet the full-area coverage requirements of future mobile communication systems, multi-band coordinated coverage is required. Among them, low frequencies are used to provide wide-area coverage and deep coverage, while high frequencies rely on large bandwidth to improve uplink throughput. The 5G New Radio (NR) network specifies two frequency ranges: FR1 and FR2. The frequency range is 450MHz to 6GHz, also known as the Sub-6GHz band; the frequency range of the FR2 band is 24.25GHz to 52.6GHz, commonly known as millimeter wave. To further increase data rates, 3GPP R17 extended the millimeter wave spectrum range from 24.25-52.6GHz to 71GHz. 3GPP also calls it the FR2-2 band, and the frequency range of FR2-2 is (52.6GHz-71GHz).

[0005] The Next Generation Radio Access Network (NG-RAN) consists of 5G base stations (also known as the next generation node, gNB) and evolved LTE base stations (NG-eNB). In a distributed architecture, the gNB provides a complete set of protocol stack functions. In a centralized architecture, the gNB is split into the gNB Central Unit (gNB-CU) and the gNB Distributed Unit (gNB-DU). As shown in Figure 1, in a centralized architecture, a gNB can consist of one gNB-CU and multiple gNB-DUs. The gNB-CU and gNB-DU each implement different protocol stack functions. From the perspective of other NG-RAN nodes and the 5GC, the gNB-CU and gNB-DU appear to be a single gNB node. The gNB-CU and gNB-DU are connected via the F1 interface, and a gNB-DU can only connect to one gNB-CU. As shown in Figure 1, gNB1 and gNB2 are connected through the Xn interface, gNB-CU and gNB-Du are connected through the F1 interface, and gNB CU-CP and gNB CU-UP are connected through the E1 interface.

[0093] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention 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 in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0094] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0095] Currently, the minimum channel bandwidth supported by 5G NR is 5MHz. With the growing demand for dedicated spectrum with available bandwidth less than 5MHz, the existing standard can be enhanced to support channel bandwidth less than 5MHz.

[0096] To further improve 5G spectrum efficiency and meet the service needs of massive 5G devices, NR supports flexible duplexing. Flexible duplexing refers to a mechanism that dynamically (dynamic TDD) or semi-statically (semi-static TDD) allocates time / frequency resources based on DL (Down Link) or UL (Up Link) service requirements. However, flexible resource allocation can lead to cross-slot interference or cross-link interference.

[0097] To achieve continuous network coverage, it is necessary to support mobility continuity for wireless terminal devices. This means that terminals can move from a source base station to a target base station while maintaining continuity of uplink and downlink data transmission. However, the source and target base stations may support different resource configurations. Furthermore, given the impact of newly added millimeter-wave high-frequency bands and new small bandwidths, the source and target base stations may support different spectrum ranges and bandwidth configurations. Therefore, when the source and target base stations support different spectrum ranges or bandwidth configurations, continuity of uplink and downlink data transmission cannot be maintained.

[0098] To address the above-mentioned problems, no effective solutions have been proposed so far.

[0099] The embodiments of the present application provide a method and apparatus for configuring extended resources to at least solve the technical problem of being unable to maintain continuity of terminal uplink and downlink data transmission when the source base station and the target base station support different spectrum ranges or bandwidth configurations.

[0100] In some embodiments of the present application, the second base station centralized entity sends a first resource configuration message to the second base station separated entity, wherein the first resource configuration message includes a small bandwidth configuration and / or a large bandwidth configuration; the second base station centralized entity receives a first request message sent by the first base station, wherein the first request message includes a small bandwidth configuration and / or a large bandwidth configuration; the small bandwidth configuration includes at least one of the following: a transmission bandwidth including 12 resource blocks, a transmission bandwidth including 15 resource blocks, a 3MHz transmission bandwidth, a subcarrier spacing of 15kHz, and a subcarrier spacing of 30kHz; the large bandwidth configuration includes at least one of the following: a data channel subcarrier spacing, a synchronization channel subcarrier spacing, and a bandwidth value; the data channel subcarrier spacing includes at least one of the following: a subcarrier spacing of 240kHz, a subcarrier spacing of 480k Hz, subcarrier spacing of 960kHz; the synchronization channel subcarrier spacing includes at least one of the following: synchronization signal block subcarrier spacing of 240kHz, synchronization signal block subcarrier spacing of 480kHz, synchronization signal block subcarrier spacing of 960kHz. The above scheme is adopted to achieve the purpose of the first base station sending the extended configuration information of the extended frequency band of the millimeter wave and / or the extended configuration information introduced for the 3MHz extended spectrum to the second base station, thereby achieving the technical effect of maintaining the continuity of data transmission in the presence of the extended configuration information introduced for the 3MHz extended spectrum and / or the extended configuration information introduced for the extended frequency band, and thus solving the technical problem that the continuity of the terminal uplink and downlink data transmission cannot be maintained when the source base station and the target base station support different spectrum ranges or bandwidth configurations.

[0114] In the field of wireless communications, to better achieve continuous network coverage, it is necessary to support mobility continuity for wireless terminal devices. That is, the terminal can move from the source base station to the target base station while maintaining the continuity of the terminal's uplink and downlink data transmission. However, the source base station and the target base station may support different resource configurations. Moreover, considering the impact of the newly added millimeter wave high frequency band and the newly added small bandwidth, the source base station and the target base station may support different spectrum ranges and bandwidth configurations. In order to ensure terminal mobility continuity, the current standard still has the following problems:

[0115] 1. The source base station cannot send the newly added millimeter-wave frequency band extension configuration to the target base station: When the source base station and the target base station support different frequency band configurations, the source base station cannot send the newly added millimeter-wave frequency band extension configuration to the target base station. Therefore, the target base station cannot pre-configure the extended frequency band resource configuration applicable to the target base station for the terminal. As a result, the terminal cannot maintain the continuity of the terminal's uplink and downlink data services during the process of moving from the source base station to the target base station.

[0116] 2. The source base station is unable to send the supported small bandwidth extension configuration to the target base station: When the source base station and the target base station support different bandwidth configurations, the source base station cannot send the supported small bandwidth extension configuration to the target base station. Therefore, the target base station cannot pre-configure the extended small bandwidth resource configuration applicable to the target base station for the terminal. As a result, the terminal cannot maintain the continuity of the terminal's uplink and downlink data services during the process of moving from the source base station to the target base station.

[0117] 3. The target base station is unable to support the corresponding extended configuration according to the instructions of the source base station: the target base station centralized entity is unable to send the newly received millimeter wave frequency band extended configuration and / or the newly received small bandwidth extended configuration to the separated entity, and is unable to instruct the separated entity to establish the corresponding extended configuration, thereby being unable to allocate the corresponding extended configuration to the terminal, thereby reducing resource utilization.

[0118] Based on the above requirements and reason analysis, the current 3GPP 5G protocol cannot meet the requirements and needs to be enhanced through new methods to meet the terminal service continuity requirements.

[0119] In order to solve the above problems, an embodiment of the present application provides a configuration method for extended resources, which is described in detail below.

[0120] FIG2 is a flow chart of a method for configuring extended resources according to an embodiment of the present application. As shown in FIG2 , the method includes the following steps:

[0121] Step S202: The second base station centralized entity sends a first resource configuration message to the second base station separated entity, where the first resource configuration message includes a small bandwidth configuration and / or a large bandwidth configuration;

[0122] Step S204: The second base station centralized entity receives a first request message sent by the first base station, wherein the first request message includes a small bandwidth configuration and / or a large bandwidth configuration.

[0123] The small bandwidth configuration includes at least one of the following: a transmission bandwidth including 12 resource blocks, a transmission bandwidth including 15 resource blocks, a 3MHz transmission bandwidth, a subcarrier spacing of 15kHz, and a subcarrier spacing of 30kHz; the large bandwidth configuration includes at least one of the following: a data channel subcarrier spacing, a synchronization channel subcarrier spacing, and a bandwidth value; the data channel subcarrier spacing includes at least one of the following: a subcarrier spacing of 240kHz, a subcarrier spacing of 480kHz, and a subcarrier spacing of 960kHz; the synchronization channel subcarrier spacing includes at least one of the following: a synchronization signal block subcarrier spacing of 240kHz, a synchronization signal block subcarrier spacing of 480kHz, and a synchronization signal block subcarrier spacing of 960kHz.

[0124] Based on the above steps, it can be seen that the source base station can send the extended frequency band resource configuration including small bandwidth configuration and / or large bandwidth configuration to the target base station through the base station interface message. After receiving the extended configuration, the target base station realizes the configuration related to the extended frequency band resources through the resource coordination process between the centralized entity and the separated entity. Since the second base station can allocate the extended frequency band resource configuration to the terminal in advance, it reduces the mobile interruption or interference problem caused by the introduction of extended time-frequency resources during the terminal's movement, improves the mobile continuity and service continuity of the terminal equipment, and guarantees the terminal business needs.

[0125] In step S202, in order to reduce the mobility interruption problem or interference problem of the terminal caused by the first base station and the second base station supporting different time-frequency resource configurations, the first base station sends a first request message to the second base station. The first request message may include but is not limited to an Xn setup request (Xn SETUP REQUEST). As shown in Figure 3, through the first request message, the first base station and the second base station can exchange application-level configuration data required for the two radio access nodes (NG-RAN node1 and NG-RAN node2) to correctly interoperate on the Xn interface (Xn-C). Specifically, the first request message may include a small bandwidth configuration and / or a large bandwidth configuration, such as at least one of a first extended cell resource configuration related to a millimeter wave extended frequency and a second extended cell resource configuration information related to a small bandwidth.

[0126] As described above, the first request message may include two types of configuration information: first extended cell resource configuration information and first extended transmission bandwidth configuration information, which are described in detail below:

[0127] Regarding the first extended cell resource configuration information: The first extended cell resource configuration information includes at least any one of the following: extended subcarrier spacing of 480 kHz, extended subcarrier spacing of 960 kHz, extended synchronization signal block subcarrier spacing of 480 kHz, and extended synchronization signal block subcarrier spacing of 960 kHz. The first extended cell resource configuration information represents configuration information introduced for the millimeter wave extended frequency band. Optionally, the transmission period included in the first extended cell resource configuration information includes at least one of the following: 0.5 ms, 0.125 ms, 0.0625 ms, and 0.3125 ms. In some embodiments, the data channel subcarrier spacing may also include 120 kHz.

[0128] From the above analysis, it can be seen that the first extended cell resource configuration information is mainly divided into two types of information: FDD information and TDD information, among which:

[0129] FDD information: includes the resource configuration of the cell served by the base station separation entity, which is divided into two categories: subcarrier spacing: includes the subcarrier spacing for the extended frequency band and the non-extended frequency band, which specifically includes at least one of 120kHz, 240kHz, 480kHz, and 960kHz; transmission period: includes the transmission period for the extended frequency band and the non-extended frequency band, which specifically includes at least one of 0.5ms, 0.125ms, 0.0625ms, and 0.3125ms;

[0132] The transmission bandwidth is expressed in terms of the number of resource blocks. The number of wireless resource blocks supported by the transmission bandwidth includes at least one of a downlink transmission bandwidth of 12 resource blocks and a downlink transmission bandwidth of 15 resource blocks. The downlink transmission bandwidth includes at least one of a downlink transmission bandwidth of 12 resource blocks and a downlink transmission bandwidth of 15 resource blocks.

[0133] The above-mentioned uplink frequency information includes supplementary uplink information, and the supplementary uplink information includes supplementary uplink transmission bandwidth. The supplementary uplink transmission bandwidth includes at least one of the following: a supplementary uplink transmission bandwidth including 12 resource blocks and a supplementary uplink transmission bandwidth including 15 resource blocks.

Optionally, the transmission period included in the second extended cell resource configuration information includes at least one of the following: 0.5 ms, 0.125 ms, 0.0625 ms, and 0.3125 ms. The millimeter wave extended frequency band may be FR2-2. If the second base station centralized entity supports the first request message, that is, if it supports the above configuration, the second base station centralized entity sends a first response message to the first base station for the first request message; if the second base station centralized entity does not support the first request message, the second base station centralized entity sends a first failure response message to the first base station for the first request message.

[0135] Specifically, the second base station establishes corresponding resource configuration according to the configuration information in the first request message, and then feeds back a first response message to the first base station. The first response message may be an Xn setup response (Xn SETUP RESPONSE).

[0136] Optionally, the first response message includes first extended cell resource configuration information, and the first extended cell resource configuration information includes at least any one of the following: extended subcarrier spacing 480kHz, extended subcarrier spacing 960kHz, extended synchronization signal block subcarrier spacing 480kHz, extended synchronization signal block subcarrier spacing 960kHz, wherein the first extended cell resource configuration information represents the configuration information introduced for the millimeter wave extended frequency band.

[0137] The above information can also be divided into two categories: FDD information and TDD information. The FDD information includes: resource configuration of the cell served by the base station separation entity, specifically including the following two types of information:

[0138] Subcarrier spacing: includes subcarrier spacing for extended frequency band and non-extended frequency band, which specifically includes at least one of 120kHz, 240kHz, 480kHz, and 960kHz;

[0139] Transmission period; including transmission periods for extended frequency band and non-extended frequency band, which specifically include at least one of 0.5ms, 0.125ms, 0.0625ms, and 0.3125ms;

[0142] Transmission period; including transmission periods for extended frequency band and non-extended frequency band, which specifically include at least one of 0.5ms, 0.125ms, 0.0625ms, and 0.3125ms;

[0143] The first response message also includes first extended transmission bandwidth configuration information, which includes at least one of the following: an extended transmission bandwidth including 12 resource blocks, or an extended transmission bandwidth including 15 resource blocks. The first extended transmission bandwidth configuration information also includes at least one of the following: uplink transmission bandwidth, downlink transmission bandwidth, and uplink frequency information. The first extended transmission bandwidth configuration information represents extended configuration information introduced for a 3MHz spectrum. The uplink transmission bandwidth includes at least one of the following: an uplink transmission bandwidth including 12 resource blocks, or an uplink transmission bandwidth including 15 resource blocks. The downlink transmission bandwidth includes at least one of the following: a downlink transmission bandwidth including 12 resource blocks, or a downlink transmission bandwidth including 15 resource blocks.

[0144] The uplink frequency information includes supplementary uplink information, the supplementary uplink information includes supplementary uplink transmission bandwidth, and the supplementary uplink transmission bandwidth includes at least one of the following: a supplementary uplink transmission bandwidth including 12 resource blocks and a supplementary uplink transmission bandwidth including 15 resource blocks.

[0145] It can be seen that the first extended transmission bandwidth configuration information is an extended resource configuration for a small bandwidth, which is similar to the first extended cell resource configuration information, and also includes FDD information and FDD information: including uplink configuration and / or downlink configuration, such as uplink transmission bandwidth and downlink transmission bandwidth, and the transmission bandwidth is expressed in the number of resource blocks; it can also include uplink frequency information: including supplementary uplink information, and the supplementary uplink information includes a supplementary uplink transmission bandwidth. The number of wireless resource blocks of the supplementary uplink transmission bandwidth can support at least one of 15PRB and 12PRB.

[0146] In some embodiments, when the second base station cannot support the extended resource configuration sent by the first base station, that is, cannot support the first request message, for example, the second base station cannot support the first extended cell resource configuration related to the millimeter wave extended frequency band, the second base station feeds back a first failure response message to the first base station. The first failure response message is, for example, Xn setup failure (Xn SETUP FAILURE), which is used to indicate that the corresponding configuration cannot be established. The first failure response message includes the reason for the request establishment failure, wherein the reason for the request establishment failure includes at least one of the following: inability to support the first request message, for example, inability to support the first extended resource configuration related to the millimeter wave frequency band; inability to support the second extended resource configuration related to the small bandwidth.

[0147] In some embodiments, the second extended cell resource configuration information also includes at least one of the following: extended synchronization signal block frequency domain information and an extended synchronization signal block transmission period.

[0148] Based on the solution provided by the above embodiment, the second base station will solve the mobility interruption problem of the terminal during the process of moving from the first base station to the second base station according to the first extended resource configuration information and the second extended resource configuration information in the received first request message. For example, if the second base station cannot support the first extended resource configuration and / or the second extended resource configuration supported by the first base station, the second base station needs to send the supported resource configuration information to the terminal through the first base station in advance to ensure the mobility continuity of the terminal;

[0149] In addition, the second base station can also use the first extended resource configuration information and / or the second extended resource configuration to solve the cross-link interference problem. For example, if the second base station supports the first extended resource configuration and / or the second extended resource configuration, the second base station needs to allocate reasonable resource configuration for the terminal that is about to move to the second base station based on the resource configuration information of the current service terminal, so as to avoid interference to other terminals due to the terminal working on the first extended resource configuration and / or the second extended resource configuration after moving to the second base station.

[0150] In the case that the second base station centralized entity does not support the first request message, the second base station centralized entity sends other resource configuration information supported by the second base station centralized entity to the first base station, and the other resource configuration information includes but is not limited to resource configuration information other than the configuration information in the first request message.

[0151] When the second base station separation entity supports the second extended configuration information, the second base station centralized entity receives a second response message to the first resource configuration message sent by the second base station separation entity; when the second base station separation entity does not support the second extended configuration information, the second base station centralized entity receives a second failure response message to the first resource configuration message sent by the second base station separation entity.

[0152] As shown in Figure 4, an application scenario of this solution is: in order to support the first extended resource configuration and / or the second extended resource configuration in the separation architecture, the second base station centralized entity CU sends a resource configuration request message (GNB-DU RESOURCE CONFIGURATION, base station separation entity resource configuration) to the second base station separation entity DU, so as to send corresponding resource configuration information to the separation entity DU. The resource configuration request message includes configuration information introduced with the millimeter wave FR2-2 frequency band, including extended resource configuration or small bandwidth related resource configuration. At this time, the second response message includes but is not limited to the base station separation entity resource configuration response (GNB-DU RESOURCE CONFIGURATION ACKNOWLEDGE)

[0153] The configuration information carried in the resource configuration request is similar to the configuration information type carried in the first resource configuration message. For example, the resource configuration request also carries extended resource configuration information for the millimeter wave FR2-2 frequency band and extended resource configuration for small bandwidth. The extended resource configuration information for the millimeter wave FR2-2 frequency band includes: FDD information, TDD information, and cell synchronization signal block transmission configuration information, where:

[0154] FDD information: Contains the resource configuration of the cell served by the base station separation entity, specifically including:

[0155] Subcarrier spacing: includes subcarrier spacing for extended frequency band and non-extended frequency band, which specifically includes at least one of 120kHz, 240kHz, 480kHz, and 960kHz;

[0156] Transmission period; including transmission periods for extended frequency band and non-extended frequency band, which specifically include at least one of 0.5ms, 0.125ms, 0.0625ms, and 0.3125ms;

[0158] Subcarrier spacing: includes subcarrier spacing for extended frequency band and non-extended frequency band, which specifically includes at least one of 120kHz, 240kHz, 480kHz, and 960kHz;

[0159] Transmission period; including transmission periods for extended frequency band and non-extended frequency band, which specifically include at least one of 0.5ms, 0.125ms, 0.0625ms, and 0.3125ms;

[0160] Regarding the cell synchronization signal block transmission configuration information: it can be applied to wireless forwarding equipment or other terminals, specifically including:

[0161] Synchronization signal block subcarrier spacing: includes subcarrier spacing for extended frequency band and non-extended frequency band, which specifically includes at least one of 120kHz, 240kHz, 480kHz, and 960kHz;

[0162] Synchronization signal block frequency domain information: the value range is 0 to the maximum ARFCN, including the SSB center frequency for the extended band;

[0163] SSB transmission period: includes transmission periods for non-extended frequency band and extended frequency band, which specifically includes at least one of 320 subframes and 640 subframes;

[0164] In the extended resource configuration for small bandwidth, it can be divided into two categories: FDD information and TDD information.

[0165] FDD information: includes uplink and / or downlink frequency domain configuration, where the uplink and downlink frequency domain configurations include: uplink transmission bandwidth: the transmission bandwidth is expressed in the number of resource blocks, and the number of wireless resource blocks can support at least one of 15PRBs and 12PRBs; downlink frequency domain configuration includes: downlink transmission bandwidth: the transmission bandwidth is expressed in the number of resource blocks, and the number of wireless resource blocks can support at least one of 15PRBs and 12PRBs;

[0166] The uplink frequency domain configuration also includes uplink frequency information: including supplementary uplink information, the supplementary uplink information includes supplementary uplink transmission bandwidth, and the number of wireless resource blocks of the supplementary uplink transmission bandwidth can support at least one of 15PRB and 12PRB.

[0167] TDD information: including transmission bandwidth: the transmission bandwidth is expressed in the number of resource blocks, and the number of wireless resource blocks can support at least one of 15PRB and 12PRB;

[0168] When the second base station separation entity is able to accept that the second resource configuration request information includes an extended resource configuration related to the millimeter wave FR2-2 frequency band and / or an extended resource configuration related to the small bandwidth, the second base station separation entity saves the received extended resource configuration information and performs resource scheduling according to the extended resource configuration information. Subsequently, the second base station separation entity may feedback a second configuration response message (GNB-DU RESOURCE CONFIGURATION ACKNOWLEDGE) to the second base station centralized entity to confirm receipt of the resource configuration information including the extended resource configuration.

[0169] Based on the above example, it can be seen that the second response message includes the third extended cell resource configuration information, and the third extended cell resource configuration information includes at least any one of the following: extended subcarrier spacing 480kHz, extended subcarrier spacing 960kHz, extended synchronization signal block subcarrier spacing 480kHz, extended synchronization signal block subcarrier spacing 960kHz, wherein the second extended cell resource configuration information represents the configuration information introduced for the millimeter wave FR2-2 extended frequency band. The transmission period included in the second extended cell resource configuration information includes at least one of the following: 0.5ms, 0.125ms, 0.0625ms, 0.3125ms. The third extended cell resource configuration information also includes at least one of the following: extended synchronization signal block frequency domain information and extended synchronization signal block transmission period, wherein the extended synchronization signal block frequency domain information includes the synchronization signal block center frequency for the millimeter wave FR2-2 extended frequency band, and the extended synchronization signal block transmission period includes the transmission period of the millimeter wave FR2-2 extended frequency band.

[0170] In some embodiments, the value range of the extended synchronization signal block frequency domain information is 0 to the maximum value of the absolute wireless channel number, and the extended synchronization signal block transmission period includes at least one of the following: 320 subframes, 640 subframes, wherein the unit of measurement of subframes is number.

[0177] The second base station determines whether to accept the terminal's handover request based on the received handover request message, the extended configuration information indication therein, and the situation of the current service terminal. If accepted, that is, if the second base station centralized entity supports the extended configuration information in the handover request message, then the third handover response message (HANDOVER REQUEST ACKNOWLEDGE) is fed back to the first base station; if the second base station centralized entity does not support the extended configuration information in the handover request message or the handover fails, the second base station centralized entity sends a handover failure message to the first base station.
