Technical Field

[0001] This application relates to the field of communication technologies, and for example, relates to a method for sending configuration information, a method for receiving configuration information, a node, and a storage medium. Background Art

[0002] The Open Radio Access Network (O-RAN) is an open radio access network architecture that can support multiple mobile communication systems, including but not limited to the Long Term Evolution (LTE) system, the LTE-Advanced system, the fifth-Generation mobile communication (5G) system, the LTE and 5G hybrid architecture system, the 5G New Radio (NR) system, and new communication systems emerging in the future development of communications, such as the sixth-Generation mobile communication (6G) system. The Subband Full Duplex (SBFD) technology is a technology that can improve the uplink (UL) coverage of the Time Division Duplexing (TDD) system, reduce the delay of UL transmission, and increase the capacity of UL transmission. It can also improve the flexible use of UL resources and DL resources in the Frequency Division Duplexing (FDD) system. By dividing a single carrier into uplink / downlink subbands and respectively sending and receiving data on the subbands, full duplex can be achieved on the base station side / terminal side. Currently, if SBFD is to be implemented in existing mobile communication systems and O-RAN, resource configuration is required, but there is no relevant research in the prior art on how to perform frequency domain resource configuration.

[0031] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0032] O-RAN is an open radio access network architecture. The radio devices in O-RAN (e.g., evolved NodeB (eNB) or next generation NodeB (gNB)) include an Open Distributed Unit (O-DU) and an Open Radio Unit (O-RU). Among them, the O-DU contains the functions of Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), Medium Access Control (MAC), and High Physical Layer (High-PHY). The O-RU contains the functions of Low Physical Layer (Low-PHY) and radio frequency processing. O-RAN opens the fronthaul interface between the O-DU and the O-RU, and control plane (C-plane) messages, user plane (U-plane) messages, synchronization plane (S-plane) messages, and management plane (M-plane) messages can be transmitted on the fronthaul interface. Among them, the control plane messages mainly carry information related to controlling the user plane messages (e.g., scheduling, beam indication, etc.), the user plane messages mainly carry Inphase / Quadrature (I / Q) data, the synchronization plane messages are mainly used to achieve time-frequency synchronization between the O-DU and the O-RU, and the management plane messages are mainly used for the management node to manage the O-RU and the O-RU to report its capabilities, etc.

[0033] The management node manages the O-RU through the management plane. For example, the management node can configure carriers for the O-RU. The management node can be a Network Configuration Protocol (NETCONF) client, O-DU, Network Management Systems (NMS), O-RAN Service Management and Orchestration (SMO) function, or other network automation platforms, etc. Figure 1 It is a schematic diagram of an O-RAN management plane architecture model provided by an embodiment. AsFigure 1 As shown, O-RAN supports two architecture models: a hierarchical model and a hybrid model. In the hierarchical model, the O-RU is completely managed by one or more O-DUs through the fronthaul interface based on M-plane or C-plane messages. In the hybrid model, in addition to the logical interface between the O-DU and the O-RU, the hybrid model allows one or more direct logical interfaces to be established between the management system and the O-RU. For example, the SMO or NMS can directly establish a logical connection with the O-RU or be routed through the O-DU to manage the O-RU. In Figure 1 the architecture model shown, usually the SMO, NMS or O-DU acts as a client (e.g., NETCONF Client), and the O-RU acts as a server (e.g., NETCONF Server). The client establishes a logical connection with the server to manage the O-RU.

[0034] With the rapid development of mobile communication technology, the SBFD technology further improves the communication coverage and reduces the communication delay. To achieve full-duplex communication within a single carrier, a carrier can be divided into SBFD subbands. The SBFD subbands include at least one of an uplink (UL) subband, a downlink (DL) subband, and a guard band, such that on the SBFD symbols of the carrier, the base station can simultaneously perform uplink reception and downlink transmission. If the terminal has full-duplex capabilities, the terminal can also simultaneously perform downlink reception and uplink transmission, thereby achieving full-duplex. Among them, the SBFD symbol is an orthogonal frequency-division multiplexing (OFDM) symbol that can perform SBFD. The SBFD symbols can be configured or predefined. For example, some or all of the DL or flexible symbols of a TDD carrier are configured as SBFD symbols.

[0035] The configuration information sending method and receiving method provided in this application can be applied to various wireless communication systems, such as LTE systems, advanced LTE systems, the fourth-generation mobile communication (4G) systems, 5G systems, LTE and 5G hybrid architecture systems, 5G NR systems, and new communication systems emerging in the future development of communication, such as 6G systems, etc. The configuration information sending method and receiving method provided in this application can also be applied to O-RAN. The configuration information sending method, receiving method, nodes, and storage medium provided in this application can achieve SBFD resource configuration, thereby realizing large-bandwidth and low-latency communication through flexible scheduling of SBFD and improving system performance.

[0036] Next, a method for sending configuration information, a method for receiving configuration information, nodes, and their technical effects will be described.

[0037] Figure 2 It is a schematic flowchart of a method for sending configuration information provided by an embodiment. As Figure 2 shown, the method provided by this embodiment is applicable to a first node (which can also be referred to as a first node device, or a first communication node, or a first device). In this embodiment, the first node is a management node, and the first node can manage a second node. The first node can be a Distributed Unit (DU), O-DU, NETCONF client, NMS, SMO, Base Band Unit (BBU), Central Unit (CU) of a base station, Operation Administration and Maintenance (OAM), or other network automation platforms, etc. The second node can be a Remote Radio Unit (RRU), O-RU, User Equipment (UE), or Active Antenna Unit (AAU). When the method provided by this embodiment is applied to O-RAN, the first node can be an O-DU, NETCONF client, NMS, SMO, BBU, or other network automation platforms, and the second node can be an RRU, O-RU, or AAU. When the method provided by this embodiment is applied to a 5G NR system or an LTE system, the first node can be a CU, DU, or OAM, and the second node can be a UE. The method includes the following steps.

[0038] S110. Determine configuration information, where the configuration information includes at least one of the first resource configuration information of the receiving carrier and the second resource configuration information of the transmitting carrier. The first resource configuration information is used to determine the Subband Full Duplex (SBFD) resources corresponding to the receiving carrier, and the second resource configuration information is used to determine the SBFD resources corresponding to the transmitting carrier.

[0039] In an embodiment, the configuration information may only include the first resource configuration information of the receiving carrier, may only include the second resource configuration information of the transmitting carrier, or may simultaneously include the first resource configuration information of the receiving carrier and the second resource configuration information of the transmitting carrier.

That is, the UL sub-band configuration includes at least one of the start frequency position of the UL sub-band, the end frequency position of the UL sub-band, the center frequency position of the UL sub-band, and the bandwidth of the UL sub-band.

[0047] The frequency position of the UL sub-band is indicated by an offset relative to the start frequency or the end frequency or the center frequency of the carrier.

[0049] When the UL sub-band configuration is the UL sub-band configuration of the received carrier, the frequency position of the UL sub-band of the received carrier is indicated by an offset relative to the start frequency or the end frequency or the center frequency of the received carrier.

[0050] For example, the start frequency position of the UL sub-band of the received carrier is indicated by an offset relative to the start frequency of the received carrier. Or, the start frequency position of the UL sub-band of the received carrier is indicated by an offset relative to the end frequency of the received carrier.

That is, the DL sub-band configuration includes at least one of the start frequency position of the DL sub-band, the termination frequency position of the DL sub-band, the center frequency position of the DL sub-band, and the bandwidth of the DL sub-band.

[0058] The frequency position of the DL sub-band is indicated by an offset relative to the start frequency, end frequency, or center frequency of the carrier.

[0059] Based on the description of the first resource configuration information and the second resource configuration information in this application, the above DL sub-band configuration can be the DL sub-band configuration of the receiving carrier or the DL sub-band configuration of the transmitting carrier.

[0060] When the DL sub-band configuration is the DL sub-band configuration of the receiving carrier, the frequency position of the DL sub-band of the receiving carrier is indicated by an offset relative to the start frequency, end frequency, or center frequency of the receiving carrier.

[0061] For example, the start frequency position of the DL sub-band of the receiving carrier is indicated by an offset relative to the start frequency of the receiving carrier.

[0068] In one embodiment, the above offset is indicated in units of K times a specific subcarrier spacing, where K is a non-zero integer; alternatively, the offset is jointly indicated in units of a specific resource block and a specific subcarrier spacing; the specific subcarrier spacing is the reference subcarrier spacing or the subcarrier spacing configured for the carrier; the subcarrier spacing corresponding to the specific resource block is the specific subcarrier spacing, that is, the specific resource block is the resource block corresponding to the specific subcarrier spacing.

[0069] The reference subcarrier spacing is determined by configuration or predefined manner; the predefined manner includes one of the following: determining the reference subcarrier spacing as the maximum value among all subcarrier spacings corresponding to the carrier, determining the reference subcarrier spacing as the maximum value among all subcarrier spacings corresponding to all carriers in the carrier group to which the carrier belongs.

[0070] In one embodiment, the guard band configuration includes the bandwidth of the guard band, and the guard band is adjacent to the UL sub-band or the guard band is adjacent to the DL sub-band. Optionally, the guard band configuration further includes indication information of the guard band; when the guard band is adjacent to the UL sub-band, the indication information is used to indicate the positional relationship between the guard band and the UL sub-band; when the guard band is adjacent to the DL sub-band, the indication information is used to indicate the positional relationship between the guard band and the DL sub-band. Alternatively, the guard band configuration includes the frequency position and the bandwidth of the guard band, where the frequency position includes at least one of the start frequency position, the termination frequency position, and the center frequency position, and the frequency position of the guard band is indicated by an offset relative to the start frequency or the termination frequency or the center frequency of the carrier. Here, the carrier can be a receive carrier or a transmit carrier.

[0071] In one embodiment, when the first resource configuration information includes the DL sub-band configuration of the received carrier and the guard band configuration of the received carrier, there is an association relationship between the DL sub-band configuration and the guard band configuration. That is, the first resource configuration information includes the configuration of one or more DL sub-bands of the received carrier and the guard band configuration associated with each DL sub-band configuration. For example, the first resource configuration information includes at least one of the following: the DL sub-band #1 configuration of the received carrier and its associated guard band #1 configuration, the DL sub-band #2 configuration of the received carrier and its associated guard band #2 configuration. Among them, guard band #1 is adjacent to DL sub-band #1 and is located on the right side of DL sub-band #1 (i.e., the frequency of guard band #1 is higher than that of DL sub-band #1), and guard band #2 is adjacent to DL sub-band #2 and is located on the left side of DL sub-band #2 (i.e., the frequency of guard band #2 is lower than that of DL sub-band #2).

[0072] In one embodiment, when the second resource configuration information includes the DL sub-band configuration of the transmitted carrier and the guard band configuration of the transmitted carrier, there is an association relationship between the DL sub-band configuration and the guard band configuration. That is, the second resource configuration information includes the configuration of one or more DL sub-bands of the transmitted carrier and the guard band configuration associated with each DL sub-band configuration. For example, the second resource configuration information includes at least one of the following: the DL sub-band #1 configuration of the transmitted carrier and its associated guard band #1 configuration, the DL sub-band #2 configuration of the transmitted carrier and its associated guard band #2 configuration. Among them, guard band #1 is adjacent to DL sub-band #1 and is located on the right side of DL sub-band #1 (i.e., the frequency of guard band #1 is higher than that of DL sub-band #1), and guard band #2 is adjacent to DL sub-band #2 and is located on the left side of DL sub-band #2 (i.e., the frequency of guard band #2 is lower than that of DL sub-band #2).

[0073] In one embodiment, the carrier satisfies at least one of the following conditions:

[0074] All received carriers belonging to the same carrier group have the same first resource configuration information;

[0075] All transmitted carriers belonging to the same carrier group have the same second resource configuration information;

[0076] The first resource configuration information of all received carriers and the second resource configuration information of all transmitted carriers belonging to the same carrier group are the same.

[0077] In one embodiment, the first node can also configure a carrier group for the received carrier and / or the transmitted carrier. Optionally, the first node configures the received carrier and / or the transmitted carrier that satisfies at least one of the following rules into the same carrier group: the same center frequency, the same bandwidth, associated with the endpoints belonging to the same time division multiplexing group in the second node, having the same transmission direction template configuration, having the same subcarrier spacing, belonging to the same cell.

[0078] In one embodiment, the first node and / or the second node may determine the carrier group to which the received carrier and / or the transmitted carrier belongs according to a predefined rule. For example, the predefined rule may be that carriers satisfying at least one of the following rules belong to the same carrier group: the same center frequency, the same bandwidth, associated with endpoints belonging to the same time division multiplexing group in the second node, having the same transmission direction template configuration, having the same subcarrier spacing, belonging to the same cell. For example, the predefined rule may be that carriers having the same center frequency and subcarrier spacing belong to the same carrier group, or the predefined rule is that carriers in the same cell belong to the same carrier group, or the predefined rule is that carriers having the same transmission direction template configuration belong to the same carrier group.

[0079] In one embodiment, the received carrier and / or the transmitted carrier belonging to the same carrier group correspond to the same SBFD time domain resource (e.g., SBFD symbol, SBFD duration, etc.). Alternatively, the SBFD time domain resources corresponding to the received carrier and / or the transmitted carrier belonging to the same carrier group overlap. Alternatively, the SBFD time domain resources corresponding to the received carrier and / or the transmitted carrier belonging to the same carrier group overlap, and the overlapping SBFD time domain resources are greater than a predefined threshold within a specific duration. For example, the specific duration may be the SBFD time domain resource configuration period, an integer multiple of the radio frame, etc.

[0080] In one embodiment, on the SBFD time domain resource, the first node and / or the second node simultaneously perform reception and transmission on the UL sub-band and the DL sub-band of a carrier respectively, or simultaneously perform reception and transmission on the UL sub-band corresponding to the received carrier and the DL sub-band corresponding to the transmitted carrier respectively. In this embodiment, the second node is a non-terminal.

[0081] In one embodiment, when the second node is a terminal and has the SBFD capability, on the SBFD time domain resource, the second node may simultaneously perform transmission and reception on the UL sub-band and the DL sub-band of a carrier respectively, or simultaneously perform transmission and reception on the UL sub-band corresponding to the received carrier and the DL sub-band corresponding to the transmitted carrier respectively.

[0082] S120. Send configuration information to the second node.

[0083] The first node sends configuration information to the second node, so that the second node can determine at least one of the SBFD resources corresponding to the received carrier and the SBFD resources corresponding to the transmitted carrier according to the configuration information.

[0084] Figure 3 It is a schematic flowchart of a method for receiving configuration information provided by an embodiment. As Figure 3As shown in the figure, the method provided in this embodiment is applicable to a second node (which can also be referred to as a second node device, or a second communication node, or a second device). In this embodiment, the first node is a management node, and the first node can manage the second node. The first node can be a DU, an O-DU, a NETCONF client, an NMS, an SMO, a BBU, a CU of a base station, an OAM, or other network automation platforms, etc. The second node can be an RRU, an O-RU, a UE, or an AAU. When the method provided in this embodiment is applied to O-RAN, the first node can be an O-DU, a NETCONF client, an NMS, an SMO, a BBU, or other network automation platforms, and the second node can be an RRU, an O-RU, or an AAU. When the method provided in this embodiment is applied to a 5G NR system or an LTE system, the first node can be a CU, a DU, or an OAM, and the second node can be a UE. The method includes the following steps.

[0085] S210. Receive the configuration information sent by the first node. The configuration information includes at least one of the first resource configuration information of the receiving carrier and the second resource configuration information of the transmitting carrier. The first resource configuration information is used to determine the sub-band full-duplex (SBFD) resources corresponding to the receiving carrier, and the second resource configuration information is used to determine the SBFD resources corresponding to the transmitting carrier.

[0086] In one embodiment, the configuration information may only include the first resource configuration information of the receiving carrier, may only include the second resource configuration information of the transmitting carrier, or may include both the first resource configuration information of the receiving carrier and the second resource configuration information of the transmitting carrier.

That is, the UL sub-band configuration includes at least one of the starting frequency position of the UL sub-band, the ending frequency position of the UL sub-band, the center frequency position of the UL sub-band, and the bandwidth of the UL sub-band.

[0094] The frequency position of the UL sub-band is indicated by an offset relative to the starting frequency or the ending frequency or the center frequency of the carrier.

[0095] Based on the description of the first resource allocation information and the second resource allocation information in this application, the above UL sub-band configuration can be the UL sub-band configuration of the receiving carrier or the UL sub-band configuration of the transmitting carrier.

[0096] When the UL sub-band configuration is the UL sub-band configuration of the receiving carrier, the frequency position of the UL sub-band of the receiving carrier is indicated by an offset relative to the starting frequency or the ending frequency or the center frequency of the receiving carrier.

That is, the DL sub-band configuration includes at least one of the start frequency position of the DL sub-band, the end frequency position of the DL sub-band, the center frequency position of the DL sub-band, and the bandwidth of the DL sub-band.

[0105] The frequency position of the DL sub-band is indicated by an offset relative to the start frequency or the end frequency or the center frequency of the carrier.

[0106] Based on the description of the first resource configuration information and the second resource configuration information in this application, the above DL sub-band configuration may be the DL sub-band configuration of the receiving carrier or the DL sub-band configuration of the transmitting carrier.

[0107] When the DL sub-band configuration is the DL sub-band configuration of the receiving carrier, the frequency position of the DL sub-band of the receiving carrier is indicated by an offset relative to the start frequency or the end frequency or the center frequency of the receiving carrier.

[0111] When the DL sub-band configuration is the DL sub-band configuration of the transmitted carrier, the frequency position of the DL sub-band of the transmitted carrier is indicated by an offset relative to the starting frequency or the ending frequency or the center frequency of the transmitted carrier.

[0112] For example, the starting frequency position of the DL sub-band of the transmitted carrier is indicated by an offset relative to the starting frequency of the transmitted carrier.

Alternatively, the center frequency position of the DL sub-band of the transmitted carrier is indicated by an offset relative to the center frequency of the transmitted carrier.

[0115] In one embodiment, the above offset is indicated in units of K times a specific subcarrier spacing, where K is a non-zero integer; alternatively, the offset is jointly indicated in units of a specific resource block and a specific subcarrier spacing; the specific subcarrier spacing is the reference subcarrier spacing or the subcarrier spacing configured for the carrier; the subcarrier spacing corresponding to the specific resource block is the specific subcarrier spacing, that is, the specific resource block is the resource block corresponding to the specific subcarrier spacing.

[0116] The reference subcarrier spacing is determined by configuration or predefined manner; the predefined manner includes one of the following: determining the reference subcarrier spacing as the maximum value among all subcarrier spacings corresponding to the carrier, and determining the reference subcarrier spacing as the maximum value among all subcarrier spacings corresponding to all carriers in the carrier group to which the carrier belongs.

[0117] In one embodiment, the guard band configuration includes the bandwidth of the guard band, and the guard band is adjacent to the UL subband or the guard band is adjacent to the DL subband. Optionally, the guard band configuration further includes indication information of the guard band; when the guard band is adjacent to the UL subband, the indication information is used to indicate the positional relationship between the guard band and the UL subband; when the guard band is adjacent to the DL subband, the indication information is used to indicate the positional relationship between the guard band and the DL subband.

Wherein, the carrier can be a receiving carrier or a transmitting carrier.

[0118] In one embodiment, when the first resource configuration information includes the DL subband configuration of the receiving carrier and the guard band configuration of the receiving carrier, there is an association relationship between the DL subband configuration and the guard band configuration. That is, the first resource configuration information includes the configuration of one or more DL subbands of the receiving carrier and the guard band configuration associated with each DL subband configuration.

[0119] In one embodiment, when the second resource configuration information includes the DL subband configuration of the transmitting carrier and the guard band configuration of the transmitting carrier, there is an association relationship between the DL subband configuration and the guard band configuration. That is, the second resource configuration information includes the configuration of one or more DL subbands of the transmitting carrier and the guard band configuration associated with each DL subband configuration.

[0120] In one embodiment, the carrier satisfies at least one of the following conditions:

[0121] All receiving carriers belonging to the same carrier group have the same first resource configuration information;

[0122] All transmit carriers belonging to the same carrier group have the same second resource configuration information;

[0123] The first resource configuration information of all receive carriers belonging to the same carrier group and the second resource configuration information of all transmit carriers are the same.

[0124] In one embodiment, the second node may be configured to receive the carrier group to which the carrier and / or transmit carrier belongs. Alternatively, the first node and / or the second node may determine the carrier group to which the receive carrier and / or transmit carrier belongs according to a predefined rule. For example, the predefined rule may be that carriers satisfying at least one of the following rules belong to the same carrier group: same center frequency, same bandwidth, associated with endpoints belonging to the same time division multiplexing group in the second node, having the same transmission direction template configuration, having the same subcarrier spacing, belonging to the same cell. For example, the predefined rule may be that carriers having the same center frequency and subcarrier spacing belong to the same carrier group, or the predefined rule may be that carriers in the same cell belong to the same carrier group, or the predefined rule may be that carriers having the same transmission direction template configuration belong to the same carrier group.

[0125] In one embodiment, receive carriers and / or transmit carriers belonging to the same carrier group correspond to the same SBFD time domain resources (e.g., SBFD symbols, SBFD duration, etc.). Alternatively, the SBFD time domain resources corresponding to receive carriers and / or transmit carriers belonging to the same carrier group overlap. Alternatively, the SBFD time domain resources corresponding to receive carriers and / or transmit carriers belonging to the same carrier group overlap, and the overlapping SBFD time domain resources are greater than a predefined threshold within a specific duration. For example, the specific duration may be an SBFD time domain resource configuration period, an integer multiple of a radio frame, etc.

[0126] In one embodiment, on the SBFD time domain resources, the first node and / or the second node simultaneously perform reception and transmission on the UL subband and DL subband of a carrier respectively, or simultaneously perform reception and transmission on the UL subband corresponding to the receive carrier and the DL subband corresponding to the transmit carrier respectively. In this embodiment, the second node is a non-terminal.

[0127] In one embodiment, when the second node is a terminal and has SBFD capabilities, on the SBFD time domain resources, the second node may simultaneously perform transmission and reception on the UL subband and DL subband of a carrier respectively, or simultaneously perform transmission and reception on the UL subband corresponding to the receive carrier and the DL subband corresponding to the transmit carrier respectively.

[0128] In one embodiment, after receiving the configuration information, the second node may determine at least one of the SBFD resources corresponding to the receive carrier and the SBFD resources corresponding to the transmit carrier according to the configuration information.

[0129] Next, some examples are provided to illustrate the resource configuration scheme provided in this application. Generally, an SBFD sub-band includes at least one of a DL sub-band and a UL sub-band, as well as a guard band. That is, an SBFD sub-band may include a DL sub-band, a UL sub-band, and a guard band, or may include a DL sub-band and a guard band, or may also include a UL sub-band and a guard band.

[0130] Example 1

[0131] Figure 4 is a schematic diagram of SBFD resources for Example 1 provided by an embodiment. As Figure 4 shown, for a receiving carrier or a transmitting carrier, assuming the center frequency of the carrier is f c , a first node may configure a UL sub-band and / or a DL sub-band for a second node. Taking the receiving carrier as an example, the configuration information includes the first resource configuration information of the receiving carrier, and the first resource configuration information includes at least one of the following: the UL sub-band configuration of the receiving carrier, the DL sub-band configuration of the receiving carrier. Taking the transmitting carrier as an example, the configuration information includes the second resource configuration information of the transmitting carrier, and the second resource configuration information includes at least one of the following: the UL sub-band configuration of the transmitting carrier, the DL sub-band configuration of the transmitting carrier.

[0132] As Figure 4 shown, the UL sub-band configuration includes: the offset UL_Offset of the starting frequency position of the UL sub-band relative to the center frequency of the carrier, and the bandwidth of the UL sub-band; the DL sub-band configuration includes: the offset DL_Offset of the starting frequency position of the DL sub-band relative to the center frequency of the carrier, and the bandwidth of the DL sub-band.

[0133] In the case where the first node configures multiple DL sub-bands for the second node, each DL sub-band configuration can be indicated separately. Figure 5 is another schematic diagram of SBFD resources for Example 1 provided by an embodiment. As Figure 5 shown, for a receiving carrier or a transmitting carrier, assuming the center frequency of the carrier is f c , a first node may configure a UL sub-band and / or two DL sub-bands for a second node. Taking the receiving carrier as an example, the configuration information includes the first resource configuration information of the receiving carrier, and the first resource configuration information includes at least one of the following: the UL sub-band configuration of the receiving carrier, the DL sub-band #1 configuration of the receiving carrier, the DL sub-band #2 configuration of the receiving carrier. Taking the transmitting carrier as an example, the configuration information includes the second resource configuration information of the transmitting carrier, and the second resource configuration information includes at least one of the following: the UL sub-band configuration of the transmitting carrier, the DL sub-band #1 configuration of the transmitting carrier, the DL sub-band #2 configuration of the transmitting carrier.

[0134] As Figure 5As shown, the UL sub-band configuration includes: the offset UL_Offset of the starting frequency position of the UL sub-band relative to the center frequency of the carrier, and the bandwidth of the UL sub-band; the DL sub-band #1 configuration includes: the offset DL_Offset#1 of the starting frequency position of the DL sub-band #1 relative to the center frequency of the carrier, and the bandwidth of the DL sub-band #1; the DL sub-band #2 configuration includes: the offset DL_Offset#2 of the starting frequency position of the DL sub-band #2 relative to the center frequency of the carrier, and the bandwidth of the DL sub-band #2.

[0135] In Example 1, the above "starting frequency position" can be replaced with "ending frequency position" or "center frequency position", and equivalent configurations can be obtained after replacement. For example, after replacing it with "ending frequency position", the UL sub-band configuration includes: the offset UL_Offset of the ending frequency position of the UL sub-band relative to the center frequency of the carrier, and the bandwidth of the UL sub-band; the DL sub-band configuration includes: the offset DL_Offset of the ending frequency position of the DL sub-band relative to the center frequency of the carrier, and the bandwidth of the DL sub-band.

[0136] Example 2

[0137] Figure 6 is a schematic diagram of SBFD resources in Example 2 provided by an embodiment. Figure 7 is another schematic diagram of SBFD resources in Example 2 provided by an embodiment. As Figure 6 and Figure 7 shown, for a receiving carrier or a transmitting carrier, assuming the center frequency of the carrier is f c , the first node can configure a UL sub-band and / or a DL sub-band for the second node. Taking the receiving carrier as an example, the configuration information includes the first resource configuration information of the receiving carrier, and the first resource configuration information includes at least one of the following: the UL sub-band configuration of the receiving carrier, the DL sub-band configuration of the receiving carrier. Taking the transmitting carrier as an example, the configuration information includes the second resource configuration information of the transmitting carrier, and the second resource configuration information includes at least one of the following: the UL sub-band configuration of the transmitting carrier, the DL sub-band configuration of the transmitting carrier.

[0138] The UL sub-band configuration includes: the offset UL_Offset of the starting frequency position (or ending frequency position) of the UL sub-band relative to the center frequency of the carrier, and the bandwidth of the UL sub-band; the DL sub-band configuration includes at least one of the following: the ending frequency of the first DL sub-band, the starting frequency of the second DL sub-band. Among them, the ending frequency of the first DL sub-band and the starting frequency of the second DL sub-band can be indicated by the offset relative to the center frequency of the carrier.

[0139] For example, generally, when the number of DL sub-bands is 2, the termination frequency position of the first DL sub-band is lower than the start frequency position of the second DL sub-band. In the case where the termination frequency of the DL sub-band is lower than the start frequency of the UL sub-band (i.e., the DL sub-band frequency is lower than the UL sub-band frequency), the DL sub-band configuration includes: the offset DL_Offset of the termination frequency position of the DL sub-band relative to the center frequency of the carrier, as Figure 6 shown; in the case where the start frequency of the DL sub-band is higher than the termination frequency of the UL sub-band (i.e., the DL sub-band frequency is higher than the UL sub-band frequency), the DL sub-band configuration includes: the offset DL_Offset of the start frequency position of the DL sub-band relative to the center frequency of the carrier, as Figure 7 shown.

[0140] For example, when the number of DL sub-bands is 1, the DL sub-band configuration can be understood as: when DL_Offset is less than or equal to UL_Offset, DL_Offset represents the offset of the termination frequency position of the DL sub-band relative to the center frequency of the carrier; when DL_Offset is greater than UL_Offset, or when DL_Offset is greater than or equal to the sum of UL_Offset and the bandwidth of the UL sub-band, DL_Offset represents the offset of the start frequency position of the DL sub-band relative to the center frequency of the carrier.

[0141] In the case where the first node configures multiple DL sub-bands for the second node, each DL sub-band configuration can be indicated separately. For example, the termination frequency of the first DL sub-band and the start frequency of the second DL sub-band are indicated. Figure 8 is another schematic diagram of SBFD resources for Example 2 provided by an embodiment. As Figure 8 shown, for a receiving carrier or a transmitting carrier, assuming the center frequency of the carrier is f c , the first node can configure one UL sub-band and / or two DL sub-bands for the second node. Taking the receiving carrier as an example, the configuration information includes the first resource configuration information of the receiving carrier, and the first resource configuration information includes at least one of the following: the UL sub-band configuration of the receiving carrier, the DL sub-band #1 configuration of the receiving carrier, the DL sub-band #2 configuration of the receiving carrier. Taking the transmitting carrier as an example, the configuration information includes the second resource configuration information of the transmitting carrier, and the second resource configuration information includes at least one of the following: the UL sub-band configuration of the transmitting carrier, the DL sub-band #1 configuration of the transmitting carrier, the DL sub-band #2 configuration of the transmitting carrier.

[0142] As Figure 8As shown, the UL sub-band configuration includes: the offset UL_Offset of the starting frequency position (or the ending frequency position) of the UL sub-band relative to the center frequency of the carrier, and the bandwidth of the UL sub-band; the DL sub-band #1 configuration includes: the offset DL_Offset#1 of the ending frequency position of the DL sub-band #1 relative to the center frequency of the carrier; the DL sub-band #2 configuration includes: the offset DL_Offset#2 of the starting frequency position of the DL sub-band #2 relative to the center frequency of the carrier.

[0143] In Example 2, the bandwidth of the DL sub-band, or the frequency range of the DL, can be implicitly determined according to the frequency range of the carrier and the configuration of the DL sub-band. For example, in the case where the DL sub-band configuration includes the offset of the starting frequency position of the DL sub-band relative to the center frequency of the carrier, the frequency range of the DL sub-band is from the starting frequency position of the DL sub-band to the ending frequency of the carrier (or the frequency of the maximum available sub-carrier of the carrier); in the case where the DL sub-band configuration includes the offset of the ending frequency position of the DL sub-band relative to the center frequency of the carrier, the frequency range of the DL sub-band is from the starting frequency of the carrier (or the frequency of the minimum available sub-carrier of the carrier) to the ending frequency position of the DL sub-band.

[0144] Example 3

[0145] For a receiving carrier or a transmitting carrier, assuming the center frequency of the carrier is f c , the first node can configure a UL sub-band and / or at least one guard band for the second node. Taking the receiving carrier as an example, the configuration information includes the first resource configuration information of the receiving carrier, and the first resource configuration information includes at least one of the following: the UL sub-band configuration of the receiving carrier, the guard band configuration of the receiving carrier. Taking the transmitting carrier as an example, the configuration information includes the second resource configuration information of the transmitting carrier, and the second resource configuration information includes at least one of the following: the UL sub-band configuration of the transmitting carrier, the guard band configuration of the transmitting carrier.

[0146] The UL sub-band configuration includes: the offset UL_Offset of the starting frequency position (or the ending frequency position) of the UL sub-band relative to the center frequency of the carrier, and the bandwidth of the UL sub-band.

[0147] Figure 9 is a schematic diagram of SBFD resources in Example 3 provided by an embodiment, Figure 10 is another schematic diagram of SBFD resources in Example 3 provided by an embodiment, Figure 11It is another schematic diagram of SBFD resources for Example 3 provided by an embodiment. Exemplarily, the guard band configuration includes indication information of the guard band and the bandwidth of the guard band. The indication information of the guard band is used to indicate the positional relationship between the guard band and the UL sub-band. For example, it is located on the left side of the UL sub-band (i.e., the frequency is lower than the UL sub-band), or on the right side (i.e., the frequency is higher than the UL sub-band), or on both sides (i.e., there are guard bands on both sides of the UL sub-band). Respectively as Figures 9 - 11 shown.

[0148] When the guard band is located on the left side of the UL sub-band, the bandwidth of the guard band is the bandwidth of the left guard band; when the guard band is located on the right side of the UL sub-band, the bandwidth of the guard band is the bandwidth of the right guard band; when the guard band is located on both sides of the UL sub-band, the bandwidth of the guard band is the bandwidth of the left guard band and also the bandwidth of the right guard band, or the bandwidth of the guard band is the sum of the bandwidths of the left and right guard bands, and the bandwidths of the left and right guard bands are equal.

[0149] Exemplarily, the guard band configuration may also only include the bandwidth of the guard band. In this case, the position of the guard band on the left side, right side or both sides of the UL sub-band can be determined by the positional relationship between the UL sub-band and the carrier. For example, if the frequency position of the UL sub-band satisfies the first condition, it is determined that the guard band is located on the right side of the UL sub-band; if the frequency position of the UL sub-band satisfies the second condition, it is determined that the guard band is located on the left side of the UL sub-band; if the frequency position of the UL sub-band does not satisfy the first condition nor the second condition, it is determined that the guard band is located on both sides of the UL sub-band. Among them, the first condition includes at least one of the following: the start frequency of the UL sub-band is lower than or equal to the start frequency of the carrier, the start frequency of the UL sub-band is lower than or equal to the frequency of the lowest available sub-carrier of the carrier, the center frequency of the UL sub-band is lower than the center frequency of the carrier. The second condition includes at least one of the following: the stop frequency of the UL sub-band is higher than or equal to the stop frequency of the carrier, the stop frequency of the UL sub-band is higher than or equal to the frequency of the highest available sub-carrier of the carrier, the center frequency of the UL sub-band is higher than the center frequency of the carrier.

[0150] Exemplarily, the guard band configuration may also include at least one of the following: the bandwidth of the left guard band, the bandwidth of the right guard band.

[0151] Optionally, the frequency in the carrier other than the UL sub-band and the guard band is the DL sub-band. For example, the DL sub-band of the transmitting carrier is the frequency in the transmitting carrier other than the UL sub-band and the guard band. The bandwidth of the guard band can be 0, that is, no guard band is configured.

[0152] Example 4

[0153] Optionally, the first node configures the same resource configuration information for all carriers belonging to the same carrier group. For example, the first resource configuration information configured for all receiving carriers belonging to the same carrier group is the same, the second resource configuration information configured for all transmitting carriers belonging to the same carrier group is the same, or the first resource configuration information and the second resource configuration information configured for all receiving carriers and transmitting carriers belonging to the same carrier group are the same.

[0154] Among them, the same configured resource configuration information includes that the parameter values in the resource configuration information are the same, or the results of the resource configuration are the same. Among them, the same results include the same configured uplink subbands and downlink subbands, or the same configured uplink subbands and guard bands, or the same configured uplink subbands, downlink subbands and guard bands.

[0155] Among them, all carriers include all receiving carriers, or all transmitting carriers, or all receiving carriers and all transmitting carriers.

[0156] The first node can configure the carrier group to which each carrier belongs, or determine carriers that satisfy at least one of the following as a carrier group: the same center frequency, the same bandwidth, associated with endpoints belonging to the same time division multiplexing group in the second node, having the same transmission direction template configuration, having the same subcarrier spacing, belonging to the same cell.

[0157] For example, the first node configures one or more transmitting carriers and one or more receiving carriers for the second node, and configures the carrier group to which each carrier is located for the second node, or defaults that all carriers in the same cell belong to the same carrier group, or defaults that carriers with the same subcarrier spacing belong to the same carrier group. For example, in O-RAN, the transmitting carrier list is configured through the parameter list tx-array-carriers, the receiving carrier list is configured through the parameter list rx-array-carriers, and the first node can configure tx-array-carrier 1 and rx-array-carrier 2 to belong to a carrier group; in NR and LTE systems, the first node can configure a list of subcarrier-spacing-specific carriers for the DL and UL of the second node through the scs-SpecificCarrierList parameter of the subcarrier-spacing-specific carrier list. The first node configures the same uplink subbands and / or downlink subbands for the carriers in this carrier group.

[0158] For example, it can be considered that the transmitting carriers and receiving carriers with the same center frequency and the same bandwidth belong to a carrier group, and the first node configures the same uplink subbands and downlink subbands for the carriers in this carrier group.

[0159] For another example, it can be considered that carriers with the same bandwidth belong to a carrier group, and the parameter values in the resource configuration information configured by the first node for the carriers in this carrier group are the same.

[0160] For another example, it can be considered that carriers with the same transmission direction template configuration (TDD pattern) belong to a carrier group, and the first node configures the same uplink subbands and downlink subbands for the carriers in this carrier group. For example, in O-RAN, there is an association relationship between endpoints and carriers. The first node usually configures the same transmission direction template for the carriers associated with the endpoints belonging to the same time division multiplexing group tdd-group. It can be considered that the carriers associated with the endpoints belonging to the same tdd-group belong to a carrier group, and the first node configures the same uplink subbands and downlink subbands for the carriers in this carrier group. Among them, the transmission direction template is the transmission direction configuration of one period, and the transmission direction includes downlink, uplink or guard interval.

[0161] Example 5

[0162] In the above embodiments or examples, the offset relative to the center frequency of the carrier can be indicated in units of K times a specific subcarrier interval, where K is a non-zero integer; or, it can be jointly indicated in units of a specific resource block and a specific subcarrier interval; the specific subcarrier interval is the reference subcarrier interval or the subcarrier interval configured for the carrier; the subcarrier interval corresponding to the specific resource block is the specific subcarrier interval.

[0163] For example, k = 12 or -12, that is, in units of the resource block (Resource Block, RB) corresponding to the specific subcarrier interval; another example is k = 6 or -6, that is, in units of half of the resource block corresponding to the specific subcarrier interval. The positive or negative value of k indicates whether it is higher or lower than the center frequency of the relative carrier. For another example, the joint indication can be that the offset relative to the center frequency of the carrier is i specific resource blocks and j specific subcarrier intervals, where i and j are integers. Preferably, the bandwidth is in units of the RB corresponding to the specific subcarrier interval.

[0164] The reference subcarrier interval is determined by configuration or predefined method; the predefined method includes one of the following: determining the reference subcarrier interval as the maximum value among all subcarrier intervals supported by the carrier, and determining the reference subcarrier interval as the maximum value among all subcarrier intervals supported by all carriers in the carrier group to which the carrier belongs.

[0165] For example, in the case where the reference subcarrier spacing corresponding to the resource configuration information of the carrier is determined by configuration, the reference subcarrier spacing satisfies at least one of the following: the reference subcarrier spacing is greater than or equal to the maximum value of all subcarrier spacings supported by the carrier, or the reference subcarrier spacing is greater than or equal to the maximum value of all subcarrier spacings supported by all carriers in the carrier group to which the carrier belongs.

[0166] For an O-RAN network, the subcarrier spacing corresponding to a carrier is the subcarrier spacing indicated by the radio frame structure frame-structure parameter configured by the first node for the endpoints in the second node. All subcarrier spacings supported by the carrier are all subcarrier spacings configured by the first node for the endpoints in the second node associated with the carrier, or the subcarrier spacings indicated by the radio frame structure parameters configured for the endpoints in all second nodes associated with the carrier. Among them, the carrier can be a transmitting carrier or a receiving carrier, and the radio frame structure is usually used to indicate the fast Fourier transform length FFT size and the subcarrier spacing.

[0167] For NR and LTE networks, a carrier is a carrier specific to a subcarrier spacing, and the subcarrier spacing corresponding to the carrier is the subcarrier spacing corresponding to the carrier specific to the subcarrier spacing configured by the first node for the second node. The carrier can be a transmitting carrier or a receiving carrier.

[0168] Example 6

[0169] In the above embodiments or examples, the "center frequency" in "the center frequency of the carrier" can be replaced with "starting frequency", or the "center frequency" in "the center frequency of the carrier" can be replaced with "ending frequency". Example 6 gives an example of replacing the "center frequency" in Example 1 with the "starting frequency".

[0170] Figure 12 It is a schematic diagram of SBFD resources in Example 6 provided by an embodiment. As Figure 12 shown, for a receiving carrier or a transmitting carrier, assuming that the starting frequency of the carrier is f s , the first node can configure a UL sub-band and / or a DL sub-band for the second node. Taking the receiving carrier as an example, the configuration information includes the first resource configuration information of the receiving carrier, and the first resource configuration information includes at least one of the following: the UL sub-band configuration of the receiving carrier, the DL sub-band configuration of the receiving carrier. Taking the transmitting carrier as an example, the configuration information includes the second resource configuration information of the transmitting carrier, and the second resource configuration information includes at least one of the following: the UL sub-band configuration of the transmitting carrier, the DL sub-band configuration of the transmitting carrier.

[0171] As Figure 12As shown, the UL sub-band configuration includes: the offset UL_Offset of the starting frequency position of the UL sub-band relative to the starting frequency of the carrier, and the bandwidth of the UL sub-band; the DL sub-band configuration includes: the offset DL_Offset of the starting frequency position of the DL sub-band relative to the starting frequency of the carrier, and the bandwidth of the DL sub-band.

[0172] When the first node configures multiple DL sub-bands for the second node, each DL sub-band configuration can be indicated separately. Figure 13 It is another schematic diagram of SBFD resources in Example 6 provided by an embodiment. As Figure 13 shown, for a receiving carrier or a transmitting carrier, assuming the starting frequency of the carrier is f s , the first node can configure one UL sub-band and / or two DL sub-bands for the second node. Taking the receiving carrier as an example, the configuration information includes the first resource configuration information of the receiving carrier, and the first resource configuration information includes at least one of the following: the UL sub-band configuration of the receiving carrier, the DL sub-band #1 configuration of the receiving carrier, and the DL sub-band #2 configuration of the receiving carrier. Taking the transmitting carrier as an example, the configuration information includes the second resource configuration information of the transmitting carrier, and the second resource configuration information includes at least one of the following: the UL sub-band configuration of the transmitting carrier, the DL sub-band #1 configuration of the transmitting carrier, and the DL sub-band #2 configuration of the transmitting carrier.

[0173] As Figure 13 shown, the UL sub-band configuration includes: the offset UL_Offset of the starting frequency position of the UL sub-band relative to the starting frequency of the carrier, and the bandwidth of the UL sub-band; the DL sub-band #1 configuration includes: the offset DL_Offset#1 of the starting frequency position of the DL sub-band #1 relative to the starting frequency of the carrier, and the bandwidth of the DL sub-band #1; the DL sub-band #2 configuration includes: the offset DL_Offset#2 of the starting frequency position of the DL sub-band #2 relative to the starting frequency of the carrier, and the bandwidth of the DL sub-band #2.

[0174] In Example 6, the above "starting frequency position" can be replaced by "ending frequency position" or "center frequency position", and equivalent configurations can be obtained after replacement. For example, after replacing it with "ending frequency position", the UL sub-band configuration includes: the offset UL_Offset of the ending frequency position of the UL sub-band relative to the starting frequency of the carrier, and the bandwidth of the UL sub-band; the DL sub-band configuration includes: the offset DL_Offset of the ending frequency position of the DL sub-band relative to the starting frequency of the carrier, and the bandwidth of the DL sub-band.

[0175] Example 7

[0176] In the above embodiments or examples, the first resource configuration information of a receiving carrier may include only the UL sub-band configuration; the second resource configuration information of a transmitting carrier may include only the DL sub-band configuration. For example, the second resource configuration information of a transmitting carrier includes at least one of the following: DL sub-band #1 configuration, DL sub-band #2 configuration.

[0177] Wherein, the UL sub-band configuration, DL sub-band configuration, DL sub-band #1 configuration, and DL sub-band #2 configuration are the same as those in the above embodiments or examples, and will not be elaborated here.

[0178] That is to say, for a receiving carrier, there is no need to configure the DL sub-band; for a transmitting carrier, there is no need to configure the UL sub-band. This can reduce the configuration overhead. Since the network side can send DL signals on the SBFD time-domain resources of the transmitting carrier in the DL sub-band, and can receive UL signals on the SBFD time-domain resources of the receiving carrier in the UL sub-band. For the terminal, it can receive DL signals on the SBFD time-domain resources of the transmitting carrier in the DL sub-band, and can transmit UL signals on the SBFD time-domain resources of the receiving carrier in the UL sub-band. Among them, the SBFD time-domain resource is the time-domain resource corresponding to the resource configuration information. For example, the SBFD time-domain resource can be the time-domain resource configured by the first node for the second node to perform sub-band full duplex, or a predefined time-domain resource that can perform sub-band full duplex. The present application does not limit the configuration method of the SBFD time-domain resource.

[0179] Exemplarily, Figure 14 is a schematic diagram of SBFD resources in Example 7 provided by an embodiment. As Figure 14 shown, for a receiving carrier, assuming the starting frequency of the carrier is f s , the first node can configure a UL sub-band for the second node. The first resource configuration information of the receiving carrier includes: the offset UL_Offset of the starting frequency position of the UL sub-band of the receiving carrier relative to the starting frequency of the receiving carrier, and the bandwidth of the UL sub-band.

[0180] Exemplarily, Figure 15 is another schematic diagram of SBFD resources in Example 7 provided by an embodiment. As Figure 15 shown, for a transmitting carrier, assuming the starting frequency of the carrier is f s , the first node can configure a DL sub-band for the second node. The second resource configuration information of the transmitting carrier includes: the offset DL_Offset of the starting frequency position of the DL sub-band of the transmitting carrier relative to the starting frequency of the transmitting carrier, and the bandwidth of the DL sub-band.

[0181] Exemplarily, in the case where the first node configures multiple DL sub-bands for the second node, each DL sub-band configuration can be indicated separately. Figure 16It is another schematic diagram of SBFD resources for Example 7 provided by an embodiment. As Figure 16 shown, for a transmitting carrier, assuming the starting frequency of the carrier is f s , the first node can configure 2 DL sub-bands for the second node. The second resource configuration information of the transmitting carrier includes: the offset DL_Offset#1 of the starting frequency position of DL sub-band #1 of the transmitting carrier relative to the starting frequency of the transmitting carrier, the bandwidth of DL sub-band #1, the offset DL_Offset#2 of the starting frequency position of DL sub-band #2 of the transmitting carrier relative to the starting frequency of the transmitting carrier, and the bandwidth of DL sub-band #2.

[0182] Of course, in this example, the "starting frequency" in "the starting frequency of the carrier" can also be replaced by "ending frequency" or "center frequency".

[0183] In all the above embodiments or examples, for the O-RAN network, when the first node configures the first resource configuration information of the receiving carrier for the second node, it can configure the first resource configuration information for each receiving carrier, or configure the first resource configuration information for the receiving endpoints of the second node associated with each receiving carrier; when the first node configures the second resource configuration information of the transmitting carrier for the second node, it can configure the second resource configuration information for each transmitting carrier, or configure the second resource configuration information for the transmitting endpoints of the second node associated with each transmitting carrier. Among them, the resource configuration information includes at least one of the following frequency positions: UL sub-band, DL sub-band, and guard band. Optionally, when configuring the first resource configuration information for each receiving carrier, the UL sub-band corresponding to the receiving endpoint of the second node associated with each receiving carrier is the intersection of the available resource blocks corresponding to the receiving endpoint and the UL sub-band of the receiving carrier; when configuring the second resource configuration information for each transmitting carrier, the DL sub-band corresponding to the transmitting endpoint of the second node associated with each transmitting carrier is the intersection of the available resource blocks corresponding to the transmitting endpoint and the DL sub-band of the transmitting carrier. Optionally, for the UL sub-band corresponding to the receiving endpoint, the receiving endpoint can receive UL data sent by the UE in the SBFD time-domain resource. For the DL sub-band corresponding to the transmitting endpoint, the transmitting endpoint can send DL data to the UE in the SBFD time-domain resource. Among them, the SBFD time-domain resource is the time-domain resource configured by the first node for the receiving and transmitting endpoints of the second node that can perform full duplex. The SBFD time-domain resource is a subset of the DL time-domain resource or the time-domain guard interval, and can be a periodic resource. For example, the SBFD time-domain resource within the SBFD time-domain resource period can be indicated by indicating the offset relative to the starting position of the SBFD time-domain resource period and the time length. For example, assuming the SBFD time-domain resource period is a 10 ms radio frame, the offset is the offset relative to the starting position of the radio frame.

[0184] In all of the above embodiments or examples, the transmitting carrier and the receiving carrier are from the perspective of the network-side device. The transmitting carrier is also referred to as the downlink carrier, and the receiving carrier is also referred to as the uplink carrier.

[0185] In all of the above embodiments or examples, optionally, the second node reports SBFD capability information to the first node. For example, it reports whether it supports SBFD.

[0186] In all of the above embodiments or examples, optionally, the second node reports the combination of the receiving antenna array and the transmitting antenna array that supports SBFD. For example, for each combination, the second node can simultaneously use the receiving antenna array and the transmitting antenna array in the same combination for receiving and transmitting respectively.

[0187] In the case of no conflict, the above embodiments or instances or examples and the features therein can be combined arbitrarily.
