Configuration information sending method, receiving method, node and storage medium Technical Field

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

[0002] 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 Long Term Evolution (LTE) system, Advanced LTE (LTE-Advanced) system, the fifth-generation mobile communication (5G) system, LTE and 5G hybrid architecture system, 5G New Radio (NR) system, and new communication systems emerging in future communication development, such as the sixth-generation mobile communication technology (6G) system. Subband Full Duplex (SBFD) technology improves uplink (UL) coverage, reduces UL transmission latency, and increases UL transmission capacity in Time Division Duplexing (TDD) systems. It also enables flexible use of UL and DL resources in Frequency Division Duplexing (FDD) systems. By dividing a single carrier into uplink and downlink subbands and transmitting and receiving data separately on these subbands, full duplexing can be achieved on the base station side and the terminal side. Currently, implementing SBFD in mobile communication systems and Open-Range Ran (O-RAN) in related technologies requires resource configuration, but there is no research on how to perform frequency domain resource allocation in related technologies.

[0030] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0031] O-RAN is an open radio access network architecture. The radio equipment in O-RAN (e.g., evolved NodeB (eNB or eNodeB), next generation NodeB (gNB)) includes an open distributed unit (O-DU) and an open radio unit (O-RU). The O-DU includes the functions of the packet data convergence protocol (PDCP), radio link control (RLC), medium access control (MAC), and high physical layer (High-PHY). The O-RU includes the functions of the low physical layer (Low-PHY) and radio frequency processing. O-RAN opens the fronthaul interface between the O-DU and O-RU, over which control plane (C-plane) messages, user plane (U-plane) messages, synchronization plane (S-plane) messages, and management plane (M-plane) messages can be transmitted. Among them, the control plane message mainly carries relevant information for controlling the user plane message (for example, scheduling, beam indication, etc.), the user plane message mainly carries in-phase or quadrature (I / Q) data, the synchronization plane message is mainly used to achieve time and frequency synchronization between the O-DU and the O-RU, and the management plane message is mainly used for the management node to manage the O-RU and report the O-RU capabilities.

[0032] 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, an O-DU, a Network Management System (NMS), an O-RAN Service Management and Orchestration (SMO) function, or other network automation platforms. Figure 1 is a schematic diagram of an O-RAN management plane architecture model provided by an embodiment. As shown in Figure 1, 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 route through the O-DU to manage the O-RU. In the architecture model shown in Figure 1, the SMO, NMS, or O-DU usually acts as a client (for example, a NETCONF client), and the O-RU acts as a server (for example, a NETCONF server). The client and the server establish a logical connection to manage the O-RU.

[0033] With the rapid development of mobile communication technology, SBFD technology has further improved the coverage of communication and reduced communication delay. In order to achieve full-duplex communication within a single carrier, a carrier can be divided into SBFD sub-bands, and the SBFD sub-bands include at least one of the uplink (UL) sub-band, the downlink (DL) sub-band and the protection band, so that on the SBFD symbols of the carrier, the base station can perform uplink reception and downlink transmission at the same time. If the terminal has full-duplex capability, the terminal can also perform downlink reception and uplink transmission at the same time, thereby achieving full-duplex. Among them, the SBFD symbol is an orthogonal frequency-division multiplexing (OFDM) symbol that can perform SBFD. The SBFD symbol can be configured or predefined, for example, configuring part or all of the DL or flexible symbols of the TDD carrier as SBFD symbols.

[0034] 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, fourth-generation mobile communication (4G) systems, 5G systems, LTE and 5G hybrid architecture systems, 5G NR systems, and new communication systems emerging in future communication developments, such as 6G systems. The configuration information sending method and receiving method provided in this application can also be applied to O-RAN. The configuration information sending method and receiving method, node, and storage medium provided in this application can implement SBFD resource configuration, thereby achieving large bandwidth, low latency communication, and improving system performance through flexible scheduling of SBFD.

[0035] The following describes the configuration information sending method, receiving method, nodes and technical effects.

[0036] Figure 2 is a flow chart of a method for sending configuration information provided by an embodiment. As shown in Figure 2, the method provided in this embodiment is applicable to a first node (also 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 the second node. The first node can be a distributed unit (DU), O-DU, NETCONF client, NMS, SMO, baseband unit (BBU), central unit (CU) of a base station, operation administration and maintenance (OAM), or other network automation platform. The second node can be a remote radio unit (RRU), O-RU, user equipment (UE), or active antenna unit (AAU). When the method provided in this embodiment is applied to O-RAN, the first node can be an O-DU, NETCONF client, NMS, SMO, BBU, or other network automation platform, and the second node can be an RRU, O-RU, or AAU. When the method provided in this embodiment is applied to a 5G NR system or an LTE system, the first node may be a CU, a DU, or an OAM, and the second node may be a UE. The method includes the following steps.

[0057] The frequency position of the DL subband is indicated by an offset relative to the start frequency, end frequency, or center frequency of the carrier.

[0058] Based on the description of the first resource configuration information and the second resource configuration information in this application, the above-mentioned DL subband configuration can be the DL subband configuration of the receiving carrier or the DL subband configuration of the transmitting carrier.

[0059] When the DL subband configuration is a DL subband configuration of a reception carrier, the frequency position of the DL subband of the reception carrier is indicated by an offset relative to a start frequency, an end frequency, or a center frequency of the reception carrier.

[0072] In one embodiment, the carrier satisfies at least one of the following conditions:

[0073] All receiving carriers belonging to the same carrier group have the same first resource configuration information;

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

[0075] The first resource configuration information of all receiving carriers and the second resource configuration information of all transmitting carriers belonging to the same carrier group are the same.

[0076] In one embodiment, the first node may further configure a carrier group for the receiving carrier and / or the transmitting carrier. Optionally, the first node may configure the receiving carriers and / or the transmitting carriers that meet at least one of the following criteria as the same carrier group: having the same center frequency, the same bandwidth, being 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, and belonging to the same cell.

[0077] In one embodiment, the first node and / or the second node may determine the carrier group to which the receiving carrier and / or the transmitting carrier belongs based on a predefined rule. For example, the predefined rule may be that carriers that meet at least one of the following rules belong to the same carrier group: the same center frequency, the same bandwidth, are associated with endpoints belonging to the same time division multiplexing group in the second node, have the same transmission direction template configuration, have the same subcarrier spacing, and belong to the same cell. For example, the predefined rule may be that carriers with 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 with the same transmission direction template configuration belong to the same carrier group.

[0078] 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.

[0079] In one embodiment, on SBFD time-domain resources, the first node and / or the second node simultaneously receives and transmits on the UL subband and DL subband of a single carrier, or simultaneously receives and transmits on the UL subband corresponding to the receiving carrier and the DL subband corresponding to the transmitting carrier. In this embodiment, the second node is a non-terminal.

[0080] In one embodiment, when the second node is a terminal and has SBFD capability, on the SBFD time domain resources, the second node can 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 receiving carrier and the DL subband corresponding to the transmitting carrier, respectively.

[0111] For example, the starting frequency position of the DL subband of the transmission carrier is indicated by an offset relative to the starting frequency of the transmission carrier. Alternatively, the starting frequency position of the DL subband of the transmission carrier is indicated by an offset relative to the ending frequency of the transmission carrier.

[0114] In one embodiment, the above-mentioned offset is indicated in units of K times a specific subcarrier spacing, where K is a non-zero integer; or, the offset is jointly indicated in units of a specific resource block and a specific subcarrier spacing; the specific subcarrier spacing is a reference subcarrier spacing or a subcarrier spacing configured for the carrier; the subcarrier spacing corresponding to the specific resource block is a specific subcarrier spacing, that is, the specific resource block is a resource block corresponding to the specific subcarrier spacing.

[0115] The reference subcarrier spacing is determined by configuration or predefined method; the predefined method includes one of the following: determining the reference subcarrier spacing as the maximum value of all subcarrier spacings corresponding to the carrier, and determining the reference subcarrier spacing as the maximum value of all subcarrier spacings corresponding to all carriers in the carrier group to which the carrier belongs.

[0116] 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 also 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.

The carrier can be a receiving carrier or a transmitting carrier.

[0117] In one embodiment, when the first resource configuration information includes a DL subband configuration of a receiving carrier and a guard band configuration of the receiving carrier, an association relationship exists 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.

[0118] In one embodiment, when the second resource configuration information includes a DL subband configuration of a transmission carrier and a guard band configuration of the transmission carrier, there is an association 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 transmission carrier and the guard band configuration associated with each DL subband configuration.

[0119] In one embodiment, the carrier satisfies at least one of the following conditions:

[0120] All receiving carriers belonging to the same carrier group have the same first resource configuration information;

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

[0122] The first resource configuration information of all receiving carriers and the second resource configuration information of all transmitting carriers belonging to the same carrier group are the same.

[0123] In one embodiment, the second node may be configured to receive the carrier and / or transmit the carrier to which the carrier group belongs. Alternatively, the first node and / or the second node may determine the carrier group to which the receiving carrier and / or the transmitting carrier belongs according to a predefined rule. For example, the predefined rule may be that carriers that meet 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, and belonging to the same cell. For example, the predefined rule may be that carriers with 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 with the same transmission direction template configuration belong to the same carrier group.

[0124] 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.

[0125] In one embodiment, on SBFD time-domain resources, the first node and / or the second node simultaneously receives and transmits on the UL subband and DL subband of a single carrier, or simultaneously receives and transmits on the UL subband corresponding to the receiving carrier and the DL subband corresponding to the transmitting carrier. In this embodiment, the second node is a non-terminal.

[0126] In one embodiment, when the second node is a terminal and has SBFD capability, on the SBFD time domain resources, the second node can 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 receiving carrier and the DL subband corresponding to the transmitting carrier, respectively.

[0127] In one embodiment, after receiving the configuration information, the second node may determine at least one of the SBFD resources corresponding to the receiving carrier and the SBFD resources corresponding to the transmitting carrier according to the configuration information.

[0128] The following examples illustrate the resource configuration scheme provided in this application. Generally, an SBFD subband includes at least one of a DL subband and a UL subband, as well as a guard band. Specifically, an SBFD subband may include a DL subband, a UL subband, and a guard band, or may include a DL subband and a guard band, or may include a UL subband and a guard band.

[0129] Example 1

[0130] FIG4 is a schematic diagram of an SBFD resource in Example 1 provided by an embodiment. As shown in FIG4 , for a receiving carrier or a transmitting carrier, assuming that the center frequency of the carrier is f c The first node can configure a UL subband and / or a DL subband for the second node. Taking a receiving carrier as an example, the configuration information includes first resource configuration information for the receiving carrier, where the first resource configuration information includes at least one of the following: a UL subband configuration for the receiving carrier and a DL subband configuration for the receiving carrier. Taking a transmitting carrier as an example, the configuration information includes second resource configuration information for the transmitting carrier, where the second resource configuration information includes at least one of the following: a UL subband configuration for the transmitting carrier and a DL subband configuration for the transmitting carrier.

[0131] As shown in Figure 4, the UL subband configuration includes: the offset UL_Offset of the starting frequency position of the UL subband relative to the center frequency of the carrier, and the bandwidth of the UL subband; the DL subband configuration includes: the offset DL_Offset of the starting frequency position of the DL subband relative to the center frequency of the carrier, and the bandwidth of the DL subband.

[0132] In the case where the first node configures multiple DL subbands for the second node, each DL subband configuration can be indicated separately. FIG5 is another schematic diagram of SBFD resources of Example 1 provided by an embodiment. As shown in FIG5, for a receiving carrier or a transmitting carrier, assuming that the center frequency of the carrier is f c , the first node can configure one UL subband and / or two DL subbands for the second node. Taking the receiving carrier as an example, the configuration information includes first resource configuration information for the receiving carrier, and the first resource configuration information includes at least one of the following: the UL subband configuration of the receiving carrier, the DL subband #1 configuration of the receiving carrier, and the DL subband #2 configuration of the receiving carrier. Taking the transmitting carrier as an example, the configuration information includes second resource configuration information for the transmitting carrier, and the second resource configuration information includes at least one of the following: the UL subband configuration of the transmitting carrier, the DL subband #1 configuration of the transmitting carrier, and the DL subband #2 configuration of the transmitting carrier.

[0133] As shown in Figure 5, the UL subband configuration includes: the offset UL_Offset of the starting frequency position of the UL subband relative to the center frequency of the carrier, and the bandwidth of the UL subband; the DL subband #1 configuration includes: the offset DL_Offset#1 of the starting frequency position of the DL subband #1 relative to the center frequency of the carrier, and the bandwidth of the DL subband #1; the DL subband #2 configuration includes: the offset DL_Offset#2 of the starting frequency position of the DL subband #2 relative to the center frequency of the carrier, and the bandwidth of the DL subband #2.

[0134] In Example 1, the above-mentioned "starting frequency position" can be replaced with "ending frequency position" or "center frequency position. After the replacement, an equivalent configuration can be obtained. For example, after being replaced with "ending frequency position", the UL subband configuration includes: the offset UL_Offset of the ending frequency position of the UL subband relative to the center frequency of the carrier, and the bandwidth of the UL subband; the DL subband configuration includes: the offset DL_Offset of the ending frequency position of the DL subband relative to the center frequency of the carrier, and the bandwidth of the DL subband.

[0135] Example 2

[0136] Figure 6 is a schematic diagram of an SBFD resource in Example 2 provided by an embodiment, and Figure 7 is a schematic diagram of another SBFD resource in Example 2 provided by an embodiment. As shown in Figures 6 and 7, for a receiving carrier or a transmitting carrier, assuming that the center frequency of the carrier is f cThe first node can configure a UL subband and / or a DL subband for the second node. Taking a receiving carrier as an example, the configuration information includes first resource configuration information for the receiving carrier, where the first resource configuration information includes at least one of the following: a UL subband configuration for the receiving carrier and a DL subband configuration for the receiving carrier. Taking a transmitting carrier as an example, the configuration information includes second resource configuration information for the transmitting carrier, where the second resource configuration information includes at least one of the following: a UL subband configuration for the transmitting carrier and a DL subband configuration for the transmitting carrier.

[0137] The UL subband configuration includes: the offset (UL_Offset) of the UL subband's starting frequency position (or ending frequency position) relative to the carrier's center frequency, and the UL subband's bandwidth. The DL subband configuration includes at least one of the following: the ending frequency of a first DL subband and the starting frequency of a second DL subband. The ending frequency of the first DL subband and the starting frequency of the second DL subband can be indicated by offsets relative to the carrier's center frequency.

[0138] For example, typically, when the number of DL subbands is 2, the end frequency position of the first DL subband is lower than the start frequency position of the second DL subband. When the end frequency of the DL subband is lower than the start frequency of the UL subband (i.e., the DL subband frequency is lower than the UL subband frequency), the DL subband configuration includes: an offset DL_Offset of the end frequency position of the DL subband relative to the center frequency of the carrier, as shown in Figure 6; when the start frequency of the DL subband is higher than the end frequency of the UL subband (i.e., the DL subband frequency is higher than the UL subband frequency), the DL subband configuration includes: an offset DL_Offset of the start frequency position of the DL subband relative to the center frequency of the carrier, as shown in Figure 7.

[0139] For example, when the number of DL subbands is 1, the DL subband configuration can be understood as: when DL_Offset is less than or equal to UL_Offset, DL_Offset represents the offset of the end frequency position of the DL subband 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 subband, DL_Offset represents the offset of the starting frequency position of the DL subband relative to the center frequency of the carrier.

[0140] In the case where the first node configures multiple DL subbands for the second node, each DL subband configuration can be indicated separately. For example, the end frequency of the first DL subband and the start frequency of the second DL subband can be indicated. Figure 8 is another SBFD resource diagram of Example 2 provided by an embodiment. As shown in Figure 8, for a receiving carrier or a transmitting carrier, assuming that the center frequency of the carrier is f c, the first node can configure one UL subband and / or two DL subbands for the second node. Taking the receiving carrier as an example, the configuration information includes first resource configuration information for the receiving carrier, and the first resource configuration information includes at least one of the following: the UL subband configuration of the receiving carrier, the DL subband #1 configuration of the receiving carrier, and the DL subband #2 configuration of the receiving carrier. Taking the transmitting carrier as an example, the configuration information includes second resource configuration information for the transmitting carrier, and the second resource configuration information includes at least one of the following: the UL subband configuration of the transmitting carrier, the DL subband #1 configuration of the transmitting carrier, and the DL subband #2 configuration of the transmitting carrier.

[0141] As shown in Figure 8, the UL subband configuration includes: the offset UL_Offset of the starting frequency position (or ending frequency position) of the UL subband relative to the center frequency of the carrier, and the bandwidth of the UL subband; the DL subband #1 configuration includes: the offset DL_Offset#1 of the ending frequency position of the DL subband #1 relative to the center frequency of the carrier; the DL subband #2 configuration includes: the offset DL_Offset#2 of the starting frequency position of the DL subband #2 relative to the center frequency of the carrier.

[0142] In Example 2, the bandwidth of the DL subband, or the frequency range of the DL, can be implicitly determined based on the frequency range of the carrier and the configuration of the DL subband. For example, when the DL subband configuration includes an offset of the starting frequency position of the DL subband relative to the center frequency of the carrier, the frequency range of the DL subband is from the starting frequency position of the DL subband to the ending frequency of the carrier (or the frequency of the maximum available subcarrier of the carrier); when the DL subband configuration includes an offset of the ending frequency position of the DL subband relative to the center frequency of the carrier, the frequency range of the DL subband is from the starting frequency of the carrier (or the frequency of the minimum available subcarrier of the carrier) to the ending frequency position of the DL subband.

[0143] Example 3

[0144] For a receiving carrier or transmitting carrier, assuming the center frequency of the carrier is f c The first node can configure a UL subband and / or at least one guard band for the second node. Taking a receiving carrier as an example, the configuration information includes first resource configuration information for the receiving carrier, where the first resource configuration information includes at least one of the following: a UL subband configuration for the receiving carrier and a guard band configuration for the receiving carrier. Taking a transmitting carrier as an example, the configuration information includes second resource configuration information for the transmitting carrier, where the second resource configuration information includes at least one of the following: a UL subband configuration for the transmitting carrier and a guard band configuration for the transmitting carrier.

[0145] The UL subband configuration includes: an offset UL_Offset of a starting frequency position (or an ending frequency position) of the UL subband relative to the center frequency of the carrier, and a bandwidth of the UL subband.

[0146] FIG9 is a schematic diagram of an SBFD resource of Example 3 provided by an embodiment, FIG10 is another schematic diagram of an SBFD resource of Example 3 provided by an embodiment, and FIG11 is yet another schematic diagram of an SBFD resource of 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, whether 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). As shown in FIG9-FIG11 respectively.

[0147] 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 both the bandwidth of the left guard band and 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.

[0148] Exemplarily, the guard band configuration may also only include the bandwidth of the guard band. In this case, the positional relationship between the UL subband and the carrier may be used to determine whether the guard band is located on the left, right, or both sides of the UL subband. For example, if the frequency position of the UL subband meets the first condition, the guard band is determined to be located on the right side of the UL subband; if the frequency position of the UL subband meets the second condition, the guard band is determined to be located on the left side of the UL subband; if the frequency position of the UL subband meets neither the first condition nor the second condition, the guard band is determined to be located on both sides of the UL subband. The first condition includes at least one of the following: the starting frequency of the UL subband is lower than or equal to the starting frequency of the carrier, the starting frequency of the UL subband is lower than or equal to the frequency of the lowest available subcarrier of the carrier, and the center frequency of the UL subband is lower than the center frequency of the carrier. The second condition includes at least one of the following: the ending frequency of the UL subband is higher than or equal to the ending frequency of the carrier, the ending frequency of the UL subband is higher than or equal to the frequency of the highest available subcarrier of the carrier, and the center frequency of the UL subband is higher than the center frequency of the carrier.

[0149] Exemplarily, the guard band configuration may also include at least one of the following: a bandwidth of a left guard band, and a bandwidth of a right guard band.

[0150] Optionally, frequencies in a carrier other than the UL subband and the guard band are DL subbands. For example, the DL subband of a transmit carrier is the frequency in the transmit carrier other than the UL subband and the guard band. The bandwidth of the guard band can be 0, i.e., no guard band is configured.

[0151] Example 4

[0152] Optionally, the first node configures the same resource configuration information for all carriers belonging to the same carrier group. For example, all receiving carriers belonging to the same carrier group are configured with the same first resource configuration information, all transmitting carriers belonging to the same carrier group are configured with the same second resource configuration information, or all receiving carriers and transmitting carriers belonging to the same carrier group are configured with the same first resource configuration information and second resource configuration information.

[0153] Configuring the same resource configuration information includes configuring the same parameter values ​​in the resource configuration information, or configuring the same resource configuration results. The same results include configuring the same uplink subband and downlink subband, or configuring the same uplink subband and guard band, or configuring the same uplink subband, downlink subband, and guard band.

[0154] Here, all carriers include all receiving carriers, or all transmitting carriers, or all receiving carriers and all transmitting carriers.

[0155] The first node can configure the carrier group to which each carrier belongs, or determine the carriers that meet at least one of the following requirements 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, and belonging to the same cell.

[0156] 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 belongs 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, and the receiving carrier list is configured through the parameter list rx-array-carriers. The first node can configure tx-array-carrier 1 and rx-array-carrier 2 to belong to the same carrier group; in NR and LTE systems, the first node can configure a list of carriers with specific subcarrier spacing for DL ​​and UL for the second node through the subcarrier spacing specific carrier list scs-SpecificCarrierList parameter. The first node configures the same uplink subband and / or downlink subband for the carriers in the carrier group.

[0157] For example, it can be considered that the transmitting carrier and the receiving carrier with the same center frequency and the same bandwidth belong to a carrier group, and the first node configures the same uplink subband and downlink subband for the carriers in the carrier group.

[0158] 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 the carrier group are the same.

[0159] For another example, carriers with the same transmission direction template configuration (TDD pattern) can be considered to belong to a carrier group, and the first node configures the same uplink subband and downlink subband for the carriers in the carrier group. For example, in O-RAN, endpoints and carriers have an associated relationship, and the first node usually configures the same transmission direction template for the carriers associated with endpoints belonging to the same time division multiplexing group (tdd-group). It can be considered that the carriers associated with endpoints belonging to the same tdd-group belong to a carrier group, and the first node configures the same uplink subband and downlink subband for the carriers in the carrier group. Among them, the transmission direction template is a periodic transmission direction configuration, and the transmission direction includes downlink, uplink, or guard interval.

[0160] Example 5

[0161] 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 spacing, where K is a non-zero integer; or, it can be jointly indicated in units of a specific resource block and a specific subcarrier spacing; the specific subcarrier spacing is a reference subcarrier spacing or a subcarrier spacing configured for the carrier; the subcarrier spacing corresponding to the specific resource block is a specific subcarrier spacing.

[0162] For example, k=12 or -12, i.e., the unit is the resource block (RB) corresponding to a specific subcarrier spacing; for another example, k=6 or -6, i.e., the unit is half of the resource block corresponding to a specific subcarrier spacing. The positive or negative value of k indicates whether the center frequency of the carrier is higher or lower. For another example, the joint indication can be that the offset of the center frequency of the carrier is i specific resource blocks and j specific subcarrier spacing, where i and j are integers. Preferably, the bandwidth is in units of RBs corresponding to a specific subcarrier spacing.

[0163] The reference subcarrier spacing is determined by configuration or predefined method; the predefined method includes one of the following: determining the reference subcarrier spacing as the maximum value of all subcarrier spacings supported by the carrier, and determining the reference subcarrier spacing as the maximum value of all subcarrier spacings supported by all carriers in the carrier group to which the carrier belongs.

[0164] For example, in the case where the reference subcarrier spacing corresponding to the resource configuration information of a 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, and 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.

[0165] For an O-RAN network, the subcarrier spacing corresponding to a carrier is the subcarrier spacing indicated by the frame-structure parameter of the radio frame structure configured by the first node for the endpoint in the second node. All subcarrier spacings supported by the carrier are all subcarrier spacings configured by the first node for the endpoint in the second node associated with the carrier, or the subcarrier spacing indicated by the radio frame structure parameter configured for the endpoints in all second nodes associated with the carrier. A carrier can be a transmitting carrier or a receiving carrier, and the radio frame structure is typically used to indicate the Fast Fourier Transform (FFT) size and subcarrier spacing.

[0166] For NR and LTE networks, a carrier is a carrier with a specific subcarrier spacing, and the subcarrier spacing corresponding to the carrier is the subcarrier spacing corresponding to the carrier with the specific subcarrier spacing configured by the first node for the second node. The carrier can be a transmitting carrier or a receiving carrier.

[0168] In the above embodiments or examples, the "center frequency" in "center frequency of the carrier" can be replaced with "starting frequency", or the "center frequency" in "center frequency of the carrier" can be replaced with "ending frequency". Example 6 provides an example of replacing "center frequency" in Example 1 with "starting frequency".

[0169] FIG12 is a schematic diagram of an SBFD resource of Example 6 provided by an embodiment. As shown in FIG12 , 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 subband and / or a DL subband for the second node. Taking a receiving carrier as an example, the configuration information includes first resource configuration information for the receiving carrier, where the first resource configuration information includes at least one of the following: a UL subband configuration for the receiving carrier and a DL subband configuration for the receiving carrier. Taking a transmitting carrier as an example, the configuration information includes second resource configuration information for the transmitting carrier, where the second resource configuration information includes at least one of the following: a UL subband configuration for the transmitting carrier and a DL subband configuration for the transmitting carrier.

[0171] In the case where the first node configures multiple DL subbands for the second node, each DL subband configuration may be indicated separately. FIG13 is another schematic diagram of SBFD resources of Example 6 provided by an embodiment. As shown in FIG13 , for a receiving carrier or a transmitting carrier, assuming that the starting frequency of the carrier is f s , the first node can configure one UL subband and / or two DL subbands for the second node. Taking the receiving carrier as an example, the configuration information includes first resource configuration information for the receiving carrier, and the first resource configuration information includes at least one of the following: the UL subband configuration of the receiving carrier, the DL subband #1 configuration of the receiving carrier, and the DL subband #2 configuration of the receiving carrier. Taking the transmitting carrier as an example, the configuration information includes second resource configuration information for the transmitting carrier, and the second resource configuration information includes at least one of the following: the UL subband configuration of the transmitting carrier, the DL subband #1 configuration of the transmitting carrier, and the DL subband #2 configuration of the transmitting carrier.

[0172] As shown in Figure 13, the UL subband configuration includes: the offset UL_Offset of the starting frequency position of the UL subband relative to the starting frequency of the carrier, and the bandwidth of the UL subband; the DL subband #1 configuration includes: the offset DL_Offset#1 of the starting frequency position of the DL subband #1 relative to the starting frequency of the carrier, and the bandwidth of the DL subband #1; the DL subband #2 configuration includes: the offset DL_Offset#2 of the starting frequency position of the DL subband #2 relative to the starting frequency of the carrier, and the bandwidth of the DL subband #2.

[0173] In Example 6, the above-mentioned "starting frequency position" can be replaced with "ending frequency position" or "center frequency position. After the replacement, an equivalent configuration can be obtained. For example, after being replaced with "ending frequency position", the UL subband configuration includes: the offset UL_Offset of the ending frequency position of the UL subband relative to the starting frequency of the carrier, and the bandwidth of the UL subband; the DL subband configuration includes: the offset DL_Offset of the ending frequency position of the DL subband relative to the starting frequency of the carrier, and the bandwidth of the DL subband.

[0174] Example 7

[0175] In the above embodiments or examples, the first resource configuration information of a receiving carrier may include only the UL subband configuration; and the second resource configuration information of a transmitting carrier may include only the DL subband configuration. For example, the second resource configuration information of a transmitting carrier may include at least one of the following: DL subband #1 configuration and DL subband #2 configuration.

[0176] Among them, the UL subband configuration, DL subband configuration, DL subband #1 configuration and DL subband #2 configuration are the same as those in the above embodiments or examples and will not be repeated here.

[0177] That is to say, for the receiving carrier, there is no need to configure the DL subband; for the transmitting carrier, there is no need to configure the UL subband. This can reduce the configuration overhead. Because the network side can send DL signals on the SBFD time domain resources of the transmitting carrier in the DL subband, and can receive UL signals on the SBFD time domain resources of the receiving carrier in the UL subband, for the terminal, it can receive DL signals on the SBFD time domain resources of the transmitting carrier in the DL subband, and can send UL signals on the SBFD time domain resources of the receiving carrier in the UL subband. Among them, the SBFD time domain resources are the time domain resources corresponding to the resource configuration information. For example, the SBFD time domain resources can be the time domain resources configured by the first node for the second node that can perform subband full-duplex, or predefined time domain resources that can perform subband full-duplex. This application does not limit the configuration method of the SBFD time domain resources.

[0178] For example, Figure 14 is a schematic diagram of an SBFD resource in Example 7 provided by an embodiment. As shown in Figure 14, for a receiving carrier, assuming that the starting frequency of the carrier is f s The first node can configure a UL subband for the second node, and the first resource configuration information of the receiving carrier includes: the offset UL_Offset of the starting frequency position of the UL subband of the receiving carrier relative to the starting frequency of the receiving carrier, and the bandwidth of the UL subband.

[0179] For example, Figure 15 is another schematic diagram of SBFD resources in Example 7 provided by an embodiment. As shown in Figure 15, for a transmitting carrier, assuming that the starting frequency of the carrier is f s The first node can configure a DL subband for the second node, and the second resource configuration information of the transmitting carrier includes: the offset DL_Offset of the starting frequency position of the DL subband of the transmitting carrier relative to the starting frequency of the transmitting carrier, and the bandwidth of the DL subband.

[0180] For example, when the first node configures multiple DL subbands for the second node, each DL subband configuration may be indicated separately. FIG16 is another schematic diagram of SBFD resources of Example 7 provided by an embodiment. As shown in FIG16 , for a transmitting carrier, assuming that the starting frequency of the carrier is f s The first node can configure two DL subbands for the second node, and the second resource configuration information of the transmitting carrier includes: the offset DL_Offset#1 of the starting frequency position of the transmitting carrier DL subband #1 relative to the starting frequency of the transmitting carrier, the bandwidth of DL subband #1, the offset DL_Offset#2 of the starting frequency position of the transmitting carrier DL subband #2 relative to the starting frequency of the transmitting carrier, and the bandwidth of DL subband #2.

[0181] Of course, in this example, the "start frequency" in the "start frequency of the carrier" can also be replaced by the "end frequency" or "center frequency".

[0182] In all of the above embodiments or examples, for an O-RAN network, the first node configures first resource configuration information for a receiving carrier for the second node. This can be configured for each receiving carrier or for each receiving endpoint of the second node associated with each receiving carrier. The first node configures second resource configuration information for a transmitting carrier for the second node. This can be configured for each transmitting carrier or for each transmitting endpoint of the second node associated with each transmitting carrier. The resource configuration information includes at least one of the following frequency locations: UL subband, DL subband, and guard band. Optionally, when the first resource configuration information is configured for each receiving carrier, the UL subband corresponding to the receiving endpoint of the second node associated with each receiving carrier is the intersection of the available resource block corresponding to the receiving endpoint and the UL subband of the receiving carrier. When the second resource configuration information is configured for each transmitting carrier, the DL subband corresponding to the transmitting endpoint of the second node associated with each transmitting carrier is the intersection of the available resource block corresponding to the transmitting endpoint and the DL subband of the transmitting carrier. Optionally, for the UL subband 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 subband corresponding to the transmitting endpoint, the transmitting endpoint can send DL data to the UE in the SBFD time domain resource. The SBFD time domain resource is a time domain resource that can perform full-duplexing and is configured by the first node for the receiving endpoint and the transmitting endpoint of the second node. 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 and time length relative to the starting position of the SBFD time domain resource period. For example, assuming that the SBFD time domain resource period is a 10ms radio frame, the offset is the offset relative to the starting position of the radio frame.

[0183] In all the above embodiments or examples, the transmitting carrier and the receiving carrier are viewed from the perspective of the network side device. The transmitting carrier is also called a downlink carrier, and the receiving carrier is also called an uplink carrier.

[0184] In all the above embodiments or examples, optionally, the second node reports SBFD capability information to the first node, for example, reports whether SBFD is supported.

[0185] In all of the above embodiments or examples, optionally, the second node reports a combination of a receive antenna array and a transmit antenna array that supports SBFD. For example, for each combination, the second node may simultaneously use the receive antenna array and the transmit antenna array in the same combination for reception and transmission, respectively.

[0186] In the absence of conflict, the above embodiments, examples or instances and features therein may be arbitrarily combined.
