[0062] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0063] 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 sequence. 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 an order 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.

[0064] As a new generation of wireless network technology, 5G has technical features such as supporting large bandwidth, large connection, low latency, and wireless cloudification. In order to meet the requirements of single-user peak rate and system capacity improvement, one of the most direct ways is to increase the system transmission bandwidth. Therefore, the LTE (Long Term Evolution)-Advanced system, an upgraded version of the long-term evolution technology, introduced a technology to increase the transmission bandwidth, namely CA (Carrier Aggregation), and continued to inherit the corresponding technical features in 5G. Dual Connectivity (DC), that is, connecting two "networks" at the same time. In order to distinguish the primary and secondary of the two "networks", the standard calls the "network" with control connection to the core network the Master Cell Group (MCG) and the other "network" the Secondary Cell Group (SCG). 5G carriers belong to the high frequency band. At the same distance, the higher the frequency, the greater the attenuation, so there will be a problem of limited 5G cell coverage. The most noteworthy issue in NR (New Radio) is the uplink coverage of UE. Therefore, the SUL technology (Supplementary Uplink) was proposed to expand the uplink coverage in the real network by configuring a low-frequency SUL carrier in an NR cell. That is, SUL / NUL+DL. The frequency band described in this patent is the frequency band Band defined in 3gpp (3rd Generation Partnership Project) protocol 38.101-1 Table 5.2-1, Table 5.4.2.3-1 and TS 38.104-Table 5.4.3.3-1.

[0065] Compared with the integrated design of 4G, 5G proposes a CU and DU separation architecture, such as Figure 2As shown, the full name of CU is Centralized Unit, which is a centralized unit (entity); the full name of DU is Distributed Unit, which is a distributed unit (entity); the division of gNB-CU and gNB-DU is based on the real-time requirements of different protocol layers. Under this principle, the physical bottom layer in the original BBU (Base Band Unit) is sunk to the AAU (Active Antenna Unit) for processing, and the physical high layers with high real-time requirements, such as MAC (Medium Access Control) and RLC (Radio Link Control) layers, are placed in the gNB-DU for processing, while the PDCP (Packet Data Convergence Protocol) and RRC (Radio Resource Control) layers with low real-time requirements are placed in the gNB-CU for processing. In the current protocol, the interface between gNB-CU and gNB-DU is the F1 interface. The initial access process is as follows: Figure 3 As shown in the figure, when the gNB-CU needs to configure a dedicated state including carrier aggregation for the UE, the gNB-CU generates an RRCReconfiguration message and encapsulates it in a DL RRC MESSAGE TRANSFER message. The gNB-DU sends the RRCReconfiguration message to the UE. An example of some specific information elements of the F1 message DL RRC MESSAGE TRANSFER is shown in the following table:

[0067] The IE / Group Name column is used to represent the name of each IE, where RRC-Container is the encapsulated downlink RRC message; the M in the Presence column indicates Mandatory, indicating that this is a parameter that must appear; the IE type and reference column is used to represent the reference corresponding to the IE, such as 9.3.1.4; the Semantics description column is used to explain the semantics of the IE, for example, the RRC-Container IE includes the DL-DCCH-Message signaling or DL-CCCH-Message signaling defined in TS 38.331[8] subclause 6.2 encapsulated in the PDCP PDU.

[0068] Low frequencies are used by operators for 5G construction, of which 800MHz (n5 band defined by 3GPP) and 900MHz (n8 band defined by 3GPP) are the focus of operators. However, when two frequency bands are used for carrier aggregation or SUL configuration, there are a series of problems for terminals, specifically:

[0069] When the terminal supports 2-antenna and 3-antenna, the following UE RF architecture can be assumed: The number of antennas is the total number of antennas supporting the main uplink / downlink and diversity downlink for all frequency bands. Due to the frequency range overlap between n5 DL and n8 UL, one possibility to enable CA_n5-n8 operation with 2-antenna implementation is to allow non-simultaneous Rx / Tx between n5 DL and n8 UL or a single UL in n5 to avoid n5REFSENS impact due to n8 UL transmission. In this way, the filter isolation between n5 DL and n8UL will not be needed anymore, and a triplexer can be used to provide semi-full-duplex carrier aggregation to a single antenna in the main path, such as Figure 4 and Figure 5 On the other hand, since the center band range of the frequency tripler exceeds the bandwidth ratio (band range divided by center frequency) of 5%, and the frequency gap between the center band and the n8 DL is only 10 MHz, this may pose a design challenge to achieve acceptable filter isolation and insertion loss.

[0070] Another architecture variant with a 2-antenna implementation is to move the n8 UL to the diversity path, such as Figure 6 As shown in Figure 2, the triplexer design in the main TRx path may be simplified due to the narrow IF range and wider frequency spacing between n5 DL and n8 DL. However, due to the wider frequency band covering n5 DL and n8 UL, the filter design challenge will be transferred to the diversity TRx path duplexer.

[0071] For the 3-antenna implementation, two of the three antennas are used for the main path to aggregate the n5 and n8 signals. Since the n5 and n8 signals do not need to be combined through a multiplexer, there is no additional insertion loss in both the n5 and n8 main signal paths compared to the single-band implementation. Having two antennas in the main signal path not only avoids the more complex multiplexer implementation and the associated additional insertion loss, but also allows each of the two antennas to have a narrower frequency coverage to support all sub-1GHz bands above 600MHz defined in 3GPP compared to a single antenna implementation that can go up to 348MHz (from n105 to n8). On the other hand, additional antennas cannot be added without taking up more space in the phone. Therefore, the feasibility of placing more than two low-band antennas in a smartphone needs to be studied, taking into account the expected narrow bandwidth and degradation of radiation performance due to form factor constraints. Although the 3-antenna implementation can help reduce the interference of n8 UL to n5 DL through antenna isolation, this is far from sufficient even in the restricted frequency range of CA operation where n8 UL does not overlap with n5 DL. Therefore, CA combination still requires semi-full-duplex operation, considering the Figure 7 The operating frequency range limits for this particular band combination are shown with non-simultaneous Rx / Tx reception / transmission between n5 DL and n8 UL.

[0072] When the base station adopts the architecture of separate gNB-CU and gNB-DU, the following problems may occur when supporting some frequency combinations of low frequency bands:

[0073] 1) gNB-DU cannot determine frequency restriction and interference control mode: According to the current protocol, gNB-DU cannot obtain the capabilities of UE, so gNB-DU cannot determine the architecture and frequency combination of UE, and therefore cannot configure the corresponding carrier aggregation / SUL or MR-DC uplink and downlink configuration status for the terminal;

[0074] 2) Base stations with separate architecture and non-separate architecture do not support the configuration of uplink and downlink transmission states that are not simultaneous: Currently, carrier aggregation, SUL, and MR-DC do not support the configuration of uplink and downlink transmission states that are not simultaneous, so gNB-CU and UE currently do not support the above configuration;

[0075] 3) When the carrier configuration changes, the gNB-DU cannot know the configuration update in time: The current UE CONTEXTMODIFICATION REQUEST message cannot indicate the updated uplink and downlink transmission configuration information to the gNB-DU.

[0076] Based on the above requirements and reason analysis, the current 3GPP Rel-18 protocols cannot meet the requirements of different transmission capacity configurations in frequency band combinations, and cannot meet the needs of network deployment and optimization.

[0077] In order to solve the above problems, relevant solutions are provided in the embodiments of the present application, which are described in detail below.

[0078] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0079] According to an embodiment of the present application, a wireless resource transmission method is provided. Figure 1 A schematic diagram of a method flow for wireless resource transmission provided in an embodiment of the present application is as follows: Figure 1 The method comprises the following steps:

[0080] Step S102, the first base station centralized entity obtains the non-concurrent transmission capability of the terminal device on one or more frequency band combinations, where the frequency band combination includes at least two uplink and / or downlink frequency bands;

[0081] In step S104, the first base station centralized entity sends the non-concurrent transmission configuration to the first base station separated entity, wherein the non-concurrent transmission configuration is used to indicate that the terminal device performs uplink transmission of the first configured frequency set and downlink transmission of the second configured frequency set at different times, and the first configured frequency set and the second configured frequency set respectively include one or more groups of continuous frequency domain resources in the frequency domain.

[0082] Specifically, the first base station centralized entity will send an indication that the uplink of the first configured frequency and the downlink of the second configured frequency in the relevant frequency band combination are not transmitted simultaneously and / or configured transmission indication information (non-concurrent transmission configuration) to the first base station separation entity, so that the first base station separation entity determines or updates the corresponding physical layer configuration according to the transmission indication information (non-concurrent transmission configuration) and performs wireless resource transmission configuration.

[0083] The wireless resource transmission method in steps S102 to S104 of the embodiment of the present application is further introduced below.

[0084] Before sending the non-concurrent transmission configuration of the terminal device to the first base station separation entity, the method also includes the following steps: obtaining non-concurrent transmission capability, wherein the non-concurrent transmission capability is sent by the terminal device to a target device in the communication network, wherein the target device includes: a core network control plane entity, a first base station and a second base station, and the non-concurrent transmission capability is used to characterize that the uplink transmission of the first configured frequency and the downlink transmission of the second configured frequency in at least two frequency bands involved in carrier aggregation, supplementary uplink SUL configuration, and dual-connection MR-DC are not transmitted at the same time, and the frequency band ranges of the first configured frequency and the second configured frequency are different.

[0085] In some embodiments of the present application, the non-concurrent transmission capability can be obtained at least in the following ways: obtaining the non-concurrent transmission capability sent by the core network control plane entity through the first core network message; or obtaining the non-concurrent transmission capability sent by the terminal device through the first RRC response message; or obtaining the non-concurrent transmission capability sent by the second base station through the first base station interface message, wherein, when the second base station serves as the anchor base station of the dual-connection MR-DC, the second base station is used to receive the non-concurrent transmission capability sent by the terminal device or the core network.

[0086] The non-concurrent transmission capability acquired by the first base station can be sent by the terminal device to the core network control plane entity (such as AMF) through a NAS message (Network Attached Storage), and then sent by the core network to the first base station centralized entity through a first core network message, or directly sent by the terminal device to the first base station centralized entity through a first RRC response message, or first sent by the terminal device or the core network to a second base station serving as an anchor base station, and then sent by the second base station to the centralized entity of the first base station.

[0087] Upon receiving the first core network message or the first RRC response message or the first base station interface message from the terminal device, the first base station centralized entity will save the non-concurrent transmission capability in the first core network message or the first RRC response message from the terminal device or the first base station interface message, wherein the first core network message includes at least: an identifier of the terminal device, a wireless capability of the terminal device, wherein the wireless capability of the terminal device includes non-concurrent transmission capability for one or more frequency band combinations; the first RRC response message includes non-concurrent transmission capability for one or more frequency band combinations, wherein the frequency band combination included in the first RRC response message is determined by the terminal device according to the frequency band combination that needs to be reported by the terminal device as indicated in the first RRC request message; the first base station interface message includes at least one of the following: an identifier of the terminal device, a wireless capability of the terminal device.

[0088] After saving the non-concurrent transmission capability, the first base station centralized entity determines the support status of the first base station separated entity for the non-concurrent transmission capability. The specific steps are as follows.

[0089] In some embodiments of the present application, the method also includes the following steps: determining whether the first base station separation entity supports non-concurrent transmission capabilities under one or more frequency band combinations through an interface message within the first base station, or determining whether the first base station separation entity supports non-concurrent transmission capabilities under one or more frequency band combinations through network management configuration.

[0090] In order to improve the perception capability of configuration updates, the method further includes the following steps: when an inter-base station interface connection is established between the first base station and the second base station or the inter-base station interface configuration is updated, the indication information of whether the first base station supports the non-concurrent transmission capability under one or more frequency band combinations is sent to the second base station through a second inter-base station interface message. Alternatively, optionally, when an inter-base station interface connection is established between the first base station and the second base station or the inter-base station interface configuration is updated, the second base station determines whether the first base station supports the non-concurrent transmission capability under one or more frequency band combinations through network management configuration.

[0091] In addition, when the second base station is the anchor base station of the terminal device in the dual-connection MR-DC configuration, the second base station determines the frequency set used by the terminal device on the first base station based on the non-concurrent transmission capability of the terminal device and the support of the first base station for the non-concurrent transmission capability, and when the first configured frequency is not used on the second base station, the first base station interface message carries the frequency and / or time domain used by the second configured frequency; when the first configured frequency and the second configured frequency are both used on the first base station, the first base station interface message carries the non-concurrent transmission capability between the first configured frequency uplink and the second configured frequency downlink of the terminal device.

[0092] After determining the support status of the first base station separation entity for the non-concurrent transmission capability, the first base station determines the non-concurrent transmission configuration according to the status and the non-concurrent transmission capability, as follows.

[0093] In some embodiments of the present application, in the case of a single link between the first base station and the terminal device, the method also includes the following steps: determining the non-concurrent transmission configuration of the first frequency band and the second frequency band combination based on information about the terminal device's non-concurrent transmission capability on the first frequency band and the second frequency band combination and / or whether the first base station separation entity supports non-concurrent transmission capability.

[0094] In the case where the first base station centralized entity determines that it is necessary to configure uplink and / or downlink carrier aggregation or SUL configuration or MR-DC configuration for the terminal device, it is sent to the first base station separation entity through a second base station internal interface request message, wherein the second base station internal interface request message includes: a terminal device identifier, a non-concurrent transmission configuration of a combination of the first frequency band and the second frequency band, and the non-concurrent transmission configuration includes at least one of the following: enabling indication information of non-concurrent transmission, time domain and / or frequency domain information corresponding to the first configured frequency uplink and / or the second configured frequency downlink;

[0095] The second base station internal interface request message may be a user context establishment request message or a user context modification request message sent by the first base station centralized entity to the first base station separated entity.

[0096] After the first base station centralized entity notifies the separation entity through the second base station internal interface request message, the separation entity feeds back RRC coding information to the terminal, and then feeds back RRC coding information to the centralized entity. The centralized entity then performs the following specific steps based on the coding information:

[0097] In some implementations of the present application, in the case where the first base station and the terminal device are single-linked, the method further includes the following steps: upon receiving the second base station internal interface response message sent by the first base station separation entity in response to the second base station internal interface request message, the first base station centralized entity obtains the non-concurrent transmission configuration of the terminal device for the first frequency band and the second frequency band combination, wherein the non-concurrent transmission configuration is encoded through RRC ASN.1, and the non-concurrent transmission configuration includes the time or time slot configuration of uplink transmission in the first frequency band and the time or time slot configuration of downlink transmission in a certain time range of the second frequency band, and at least one of the uplink frequency set of the first frequency band and the downlink frequency set of the second frequency band.

[0098] After obtaining the second base station internal interface response message sent by the first base station separation entity, the first base station centralized entity obtains the non-concurrent transmission configuration encoded by RRC ASN.1 and generates a second RRC message, wherein, when it is necessary to configure uplink and / or downlink carrier aggregation or SUL configuration for the terminal device, the non-concurrent transmission configuration of the first frequency band and the second frequency band combination is determined according to the non-concurrent transmission configuration of the terminal device sent by the first base station separation entity, and when de-configuring uplink and / or downlink carrier aggregation or SUL configuration or MR-DC configuration, the second RRC message only includes the identifier of the first carrier or the second carrier, and does not include the non-concurrent transmission configuration; the second RRC message is sent to the first base station separation entity via a third base station internal interface message.

[0099] In the case where the first base station is a secondary base station for dual connection of the terminal device, the first base station centralized entity sends the second RRC message to the second base station through a third base station interface message, wherein the third base station interface message also includes the user identifier of the user in the second base station and the first base station, and the second RRC message is encapsulated using the ASN.1 abstract syntax notation format of the wireless access technology where the first base station is located.

[0100] After receiving the second RRC message, the first base station separation entity will forward it to the terminal device for subsequent wireless resource configuration, and this process will be described in detail in subsequent embodiments.

[0101] According to an embodiment of the present application, another wireless resource transmission method is also provided, which is applied to a first base station separation entity. Figure 8 A schematic diagram of another method flow for transmitting wireless resources according to an embodiment of the present application is shown as follows: Figure 8 The method comprises the following steps:

[0102] Step S802: The first base station separation entity receives a non-concurrent transmission configuration sent by the first base station concentration entity, wherein the non-concurrent transmission configuration is used to indicate that uplink transmission of a first configured frequency set and downlink transmission of a second configured frequency set are not performed simultaneously, and the first configured frequency set and the second configured frequency set include one or more groups of frequency domain resources that are continuous in the frequency domain;

[0103] Step S804: performing wireless resource transmission configuration of the terminal device according to the non-concurrent transmission configuration.

[0104] The following further introduces the wireless resource transmission method in steps S802 to S804 of the embodiment of the present application.

[0105] When the first base station and the terminal device are single-linked, when the first base station separation entity receives the second base station internal interface request message sent by the first base station centralized entity and the second base station internal interface request message carries the non-concurrent transmission configuration of the first frequency band and the second frequency band combination, the first base station separation entity determines, based on the non-concurrent transmission configuration, that the first configured frequency uplink and the second configured frequency downlink cannot be transmitted simultaneously on the corresponding configured frequencies or can only be transmitted downlink or uplink at the time indicated by the time domain information of the non-concurrent transmission configuration, wherein the second base station internal interface request message includes: terminal device identification, non-concurrent transmission configuration of the first frequency band and the second frequency band combination, and the non-concurrent transmission configuration includes at least one of the following: enabling indication information of non-concurrent transmission, time domain and / or frequency domain information corresponding to the first configured frequency uplink and / or the second configured frequency downlink.

[0106] After determining that the first configured frequency uplink and the second configured frequency downlink cannot be transmitted simultaneously on the corresponding configured frequencies or can only be transmitted downlink or uplink at the time indicated by the time domain information of the non-concurrent transmission configuration, the first base station separation entity encodes the relevant configuration information in RRC ASN.1 format and sends it to the first base station centralized entity through an interface response message within the second base station.

[0107] When the first base station centralized entity receives the second base station internal interface response message sent by the first station separation entity in response to the second base station internal interface request message, it determines the non-concurrent transmission configuration of the terminal device based on the RRC coding information fed back by the separation entity, generates a second RRC message, and sends it to the first base station separation entity.

[0108] Among them, when the first base station and the terminal device are single-linked, the centralized entity will directly send the second RRC message to the first base station separation entity through the third base station internal interface message, and the first base station separation entity will send it to the terminal device. The specific steps are as follows.

[0109] The first base station separation entity extracts a second RRC message from the received third base station internal interface message, and sends the second RRC message to the terminal device, wherein the second RRC message is determined by the centralized entity of the first base station based on the information about the terminal device's non-concurrent transmission capability on the combination of the first frequency band and the second frequency band and / or whether the first base station separation entity supports the non-concurrent transmission capability, and the non-concurrent transmission capability is used to characterize that the uplink transmission of the first configured frequency and the downlink transmission of the second configured frequency in at least two frequency bands involved in carrier aggregation, supplementary uplink SUL configuration, and dual connection MR-DC are not performed simultaneously.

[0110] When the first base station is a secondary base station for dual connection of the terminal device, the first base station centralized entity will first send the second RRC message to the second base station through the third base station interface message, and then the second base station will encapsulate the received second RRC message in the third RRC message and send it to the terminal device.

[0111] In the case of a single link between the first base station and the terminal device, the method also includes: when the interface request message within the second base station does not carry the non-concurrent transmission configuration of the combination of the first frequency band and the second frequency band, and the first base station separation entity has been configured with the non-concurrent transmission configuration, determining that the terminal device does not perform non-concurrent transmission during carrier aggregation or SUL configuration or MR-DC configuration.

[0112] After the terminal device receives the second RRC message sent by the first base station separation entity or the second base station, the terminal device performs wireless resource configuration according to the second RRC message. The specific steps are as follows.

[0113] In some embodiments of the present application, the method also includes the following steps: after the receiving terminal device configures the carrier resources including the first configured frequency and the second configured frequency according to the carrier aggregation configuration or the supplementary uplink SUL configuration or the MR-DC configuration in the second RRC message, an RRC configuration completion message returned by the fourth RRC message.

[0114] Specifically, when the first base station and the terminal device are in a single link, after the configuration is completed, the terminal device directly feeds back a completion message to the first base station separation entity through the fourth RRC message.

[0115] In some embodiments of the present application, when the first base station is a secondary base station for dual connection of the terminal device, after the terminal device configures the carrier resources including the first configured frequency and the second configured frequency according to the second RRC message encapsulated in the third RRC message, the terminal device sends a fifth RRC message encapsulating the fourth RRC message to the second base station serving as an anchor point; when the second base station receives the fifth RRC message, the fourth RRC message in the fifth RRC message is sent to the first base station centralized entity; the method also includes: receiving a third base station internal interface message sent by the first base station centralized entity after receiving the fourth RRC message, wherein the third base station internal interface message includes a non-concurrent transmission configuration.

[0116] Specifically, when the first base station is a secondary base station for dual connection of the terminal device, after the configuration is completed, the terminal device first encapsulates the fourth RRC message in the fifth RRC message and sends it to the second base station, which is then forwarded by the second base station to the first base station centralized entity, and then sent by the first base station centralized entity to the first base station separated entity.

[0117] After receiving the configuration completion message fed back by the terminal, the first base station determines that the first configured frequency uplink and the second configured frequency downlink are performed in different time domains and / or frequency domains based on the non-concurrent transmission configuration and carrier aggregation configuration or supplementary uplink SUL configuration or MR-DC configuration.

[0118] Through the above steps, the first base station centralized entity sends the transmission indication information to the first base station separation entity through the first base station internal interface message, and the first base station separation entity determines or updates the corresponding physical layer configuration, thereby achieving the purpose of completing the indication of the uplink and downlink resource transmission status in the specific carrier aggregation configuration in the separation architecture, thereby solving the technical problem that the base station separation entity cannot obtain the capabilities of the user terminal and cannot configure the corresponding carrier aggregation or supplement the uplink or uplink and downlink status of the dual-link dual connection for the terminal due to the current protocol being unable to meet the different transmission capability configuration requirements in the frequency band combination.
