[0102] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0103] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

[0104] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0105] In some embodiments, network device 102 includes, but is not limited to, at least one of access network device and core network device.

[0106] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0107] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0108] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0109] In some embodiments, the core network equipment may be a single device comprising multiple network elements, or it may be multiple devices or a group of devices, each comprising all or part of the multiple network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of the Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0110] In this embodiment of the disclosure, the prerequisite for implementing SBFD technology is configuring SBFD subbands, which include uplink subbands (UL subband), downlink subbands (DL subband), and guard bands. In related technologies, the UL subband and DL subband can be explicitly configured through higher-layer signaling.

[0111] When configuring UL subband frequency domain resources, the configuration method of the Band Width Part (BWP) can be reused as much as possible. That is, the Common Resource Block #0 (CRB#0) is used as a reference point to indicate the starting resource block (RB) index of the UL subband and the number of RBs it contains.

[0112] For DL ​​subband, frequency domain resources can be configured using a similar method as for UL subband. However, this will obviously result in a larger configuration signaling overhead.

[0113] To reduce the signaling overhead of subband configuration and improve the feasibility and reliability of subband full-duplex communication, this disclosure provides the following methods for determining resources, as well as terminals, network devices, systems, and storage media.

[0114] Figure 2A is an interactive schematic diagram illustrating a method for determining resources according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a method for determining resources, the method including:

[0115] In step S2100, network device 102 determines the first frequency domain resources occupied by the first sub-band.

[0116] In some embodiments, network device 102 configures the first frequency domain resource via explicit signaling.

[0117] In one example, the signaling may include, but is not limited to, at least one of the following: Radio Resource Control (RRC) signaling; Downlink Control Information (DCI); Media Access Control Element (MAC CE).

[0118] In some embodiments, the first subband may be an uplink subband or a downlink subband, and this disclosure does not limit this.

[0119] In some embodiments, network device 102 may configure the starting RB index of the first subband and the number of RBs included.

[0120] In step S2101, terminal 101 determines the first frequency domain resources occupied by the first sub-band.

[0121] In some embodiments, terminal 101 may determine the first frequency domain resource in the following manner:

[0122] The receiving network device 102 displays the starting RB index and the number of RBs included in the first subband configured by the display signaling. The terminal 101 can use CRB#0 as a reference point to determine the location of the starting RB based on the starting RB index, and can determine the range of the first frequency domain resources based on the number of included RBs and the starting RB.

[0123] The above is merely an illustrative example, and this disclosure does not limit the method for determining the first frequency domain resources.

[0124] In step S2102, network device 102 determines at least one offset based on a predefined method.

[0125] In some embodiments, the offset is the offset of the second frequency domain resources occupied by the second sub-band relative to the first frequency domain resources.

[0126] In some embodiments, the transmission direction of the second subband may be different from that of the first subband.

[0127] For example, the first sub-band can be an uplink sub-band, and the second sub-band can be a downlink sub-band. As another example, the first sub-band can be a downlink sub-band, and the second sub-band can be an uplink sub-band.

[0128] Of course, the transmission direction of the second subband can also be the same as that of the first subband. For example, both the first and second subbands can be downlink subbands, and this disclosure does not limit this. In some embodiments, the network device 102 can determine at least one offset based on a predefined method.

[0129] For example, at least one offset can be agreed upon by the protocol, and the terminal 101 determines each offset based on the protocol agreement.

[0130] In step S2103, network device 102 sends third instruction information to terminal 101.

[0131] In some embodiments, terminal 101 receives third instruction information.

[0132] In some embodiments, the third indication information is used to indicate at least one offset.

[0133] In some embodiments, terminal 101 may report its capabilities in advance to inform network device 102 whether it supports multiple offsets. If terminal 101 supports multiple offsets, network device 102 may indicate multiple offsets through third indication information.

[0134] In some embodiments, network device 102 may carry the third indication information via at least one of RRC signaling, DCI, and MAC CE.

[0135] In some embodiments, terminal 101 receives third indication information to determine at least one offset.

[0136] In some embodiments, when there are multiple offsets, the values ​​of the multiple offsets may be the same or different, and this disclosure does not limit this.

[0137] In some embodiments, steps S2102 and S2103 can be executed selectively. For example, if network device 102 and terminal 101 determine at least one offset based on a predefined method, then step S2102 can be executed. As another example, if network device 102 configures at least one offset for terminal 101, then step S2103 can be executed.

[0138] In step S2104, terminal 101 determines at least one offset.

[0139] In some embodiments, terminal 101 may determine at least one offset based on a predefined method. For example, at least one offset may be agreed upon by a protocol, and terminal 101 may determine each offset based on the protocol agreement.

[0140] For example, terminal 101 may determine at least one offset within the carrier, band, subcarrier spacing (SCS), and BWP.

[0141] In some embodiments, terminal 101 may determine at least one offset based on third indication information.

[0142] In some embodiments, terminal 101 may determine at least one offset based on a predefined method and third indication information.

[0143] In one example, the set of offsets can be agreed upon by the protocol, including one or more offsets. The network device 102 indicates the index of at least one offset through third indication information. At this time, the terminal can determine at least one offset from the set of offsets based on the index of the offset indicated by the network device 102.

[0144] For example, if the set of offsets agreed upon in the protocol is {offset #1, offset #2, offset #3, offset #4, offset #5, ...}, and the index indicated by the network device 102 through the third indication information is {1, 3}, then the terminal 101 determines that there are a total of 2 offsets, namely offset #1 and offset #3.

[0145] The above is merely an illustrative example, and this disclosure does not limit the method by which the terminal 101 determines the offset.

[0146] In step S2105, network device 102 determines the number of second subbands based on a predefined method.

[0147] In some embodiments, network device 102 may determine the number of the second subband based on the relationship of the first subband in the active BWP. The number of the second subband may be one or more, and this disclosure does not limit this.

[0148] In one example, if the first subband is located on the side where the BWP is active, then network device 102 determines that the number of the second subband is 1.

[0149] In one example, if the first subband is located in the middle of the active BWP, then network device 102 determines that the number of the second subband is 2.

[0150] The transmission mode of the activated BWP can be the same as the transmission direction of the second subband. For example, if the second subband is a downlink subband, then the activated BWP can be an activated downlink BWP.

[0151] In step S2106, network device 102 sends first instruction information to terminal 101.

[0152] In some embodiments, terminal 101 receives first instruction information.

[0153] In some embodiments, the first indication information may be used to indicate the number of second sub-bands.

[0154] In one example, network device 102 may carry the first indication information via at least one of RRC signaling, DCI, or MAC CE.

[0155] In one example, the number of second subbands can be one or more.

[0156] In some embodiments, steps S2105 and S2106 can be executed in one of them. For example, when both terminal 101 and network device 102 determine the number of second sub-bands based on a predefined method, step S2105 can be executed. Or, for example, when network device 102 configures the number of second sub-bands for terminal 101, step S2106 can be executed.

[0157] In step S2107, terminal 101 determines the number of the second sub-band.

[0158] In some embodiments, terminal 101 may determine the number of the second sub-bands based on a predefined method.

[0159] For example, the number of second subbands can be determined based on the relationship of the first subband in the active bandwidth portion (BWP).

[0160] In one example, the first sub-band is located on the side of the active BWP. For example, if the lowest RB of the first sub-band is the same RB as the lowest RB of the active BWP, the terminal 101 can determine that the number of the second sub-band is 1, as shown in Figure 2B.

[0161] In one example, the first sub-band is located on the side of the active BWP. For example, if the highest RB of the first sub-band is the same as the highest RB of the active BWP, the terminal 101 can determine that the number of the second sub-band is 1, as shown in Figure 2C.

[0162] In one example, the first subband is located in the middle of the activated BWP. For example, the lowest RB of the first subband is different from the lowest RB of the BWP, and the highest RB of the first subband is different from the highest RB of the BWP. The number of the second subband is determined to be 2, as shown in Figure 2D.

[0163] In step S2108, network device 102 determines the correspondence based on a predefined method.

[0164] In some embodiments, the correspondence is the correspondence between the second sub-band and the offset.

[0165] In one example, a second subband can correspond to an offset.

[0166] Of course, a second sub-band can also correspond to two or more offsets. For example, offsets #1 and #3 correspond to second sub-band #1, and offsets #2 and #4 correspond to second sub-band #2.

[0167] Alternatively, one offset may correspond to multiple second sub-bands. For example, offset #1 corresponds to second sub-band #1 and offset #2. This disclosure does not limit this.

[0168] In some embodiments, the correspondence may be agreed upon by a protocol.

[0169] For example, the first offset in the offset value list indicates the number of RBs between the lowest RB of the first subband and the highest RB of the second subband #1, and the second offset in the offset value list indicates the number of RBs between the highest RB of the first subband and the lowest RB of the second subband #2.

[0170] For example, it can be directly agreed that the index of each offset is the same as the index of the corresponding second sub-band, with offset #1 corresponding to second sub-band #1 and offset #2 corresponding to second sub-band #2.

[0171] In step S2109, network device 102 sends second instruction information to terminal 101.

[0172] In some embodiments, terminal 101 receives second instruction information.

[0173] In some embodiments, the second indication information is used to indicate the correspondence between the second sub-band and the offset.

[0174] In one example, a second subband can correspond to an offset.

[0175] For example, the second indication information indicates that offset #1 corresponds to the second sub-band #1, and offset #2 corresponds to the second sub-band #2.

[0176] Of course, a second sub-band can also correspond to two or more offsets. For example, the second indication information indicates that offset #1 and offset #3 correspond to the second sub-band #1, and offset #2 and offset #4 correspond to the second sub-band #2.

[0177] Alternatively, one offset may correspond to multiple second sub-bands, and this disclosure does not limit this. For example, the second indication information indicates that offset #1 corresponds to second sub-band #1 and offset #2.

[0178] In one example, network device 102 may carry the second indication information via at least one of RRC signaling, DCI, or MAC CE.

[0179] In some embodiments, steps S2108 and S2109 can be executed selectively. For example, when both terminal 101 and network device 102 determine the correspondence based on a predefined method, step S2108 can be executed, but step S2109 can be omitted. As another example, when network device 102 configures the correspondence for terminal 101, step S2109 can be executed, but step S2108 can be omitted.

[0180] In some embodiments, steps S2108 and S2109 may both be executed. For example, one or more correspondences may be agreed upon by a protocol, and one of the correspondences may be indicated by the network device 102 through the second indication information.

[0181] In some embodiments, steps S2108 and S2109 are optional execution steps. For example, when the number of second sub-bands is 1, one or more offsets correspond to the second sub-band, and steps S2108 and S2109 may not be executed.

[0182] In step S2110, terminal 101 determines the correspondence.

[0183] In some embodiments, terminal 101 may determine the correspondence based on a predefined method.

[0184] For example, the correspondence can be defined by an agreement.

[0185] For example, the first offset in the offset value list indicates the number of RBs between the lowest RB of the first subband and the highest RB of the second subband #1, and the second offset in the offset value list indicates the number of RBs between the highest RB of the first subband and the lowest RB of the second subband #2.

[0186] For example, it can be directly agreed that the index of each offset is the same as the index of the corresponding second sub-band, with offset #1 corresponding to second sub-band #1 and offset #2 corresponding to second sub-band #2.

[0187] In some embodiments, terminal 101 may determine the above correspondence based on the second indication information sent by network device 102.

[0188] In step S2111, terminal 101 determines the second frequency domain resource based on the first frequency domain resource and the offset.

[0189] In some embodiments, the terminal 101 may take the first frequency domain resources occupied by the first sub-band as a reference, for example, the first RB in the first frequency domain resources as a reference, and determine the second RB in the second frequency domain resources occupied by the second sub-band based on the offset corresponding to each second sub-band.

[0190] The first RB can be an RB of the first subband, such as the lowest RB, the highest RB, or other specified RB.

[0191] The second RB can be an RB of the first subband, for example, the second RB can be the lowest RB, the highest RB or other specified RB.

[0192] In case 1-1, the number of the second sub-band is 1, and the number of offsets is also 1.

[0193] Terminal 101 can use the first RB in the first frequency domain resource as a reference and determine the second RB in the second sub-band based on the offset corresponding to the second sub-band.

[0194] For example, the second sub-band #1 corresponds to offset #1, where the first RB is the lowest RB of the first sub-band and the second RB is the highest RB of the second sub-band. Then, the terminal 101 can determine the index of the highest RB of the second sub-band by the sum of the index of the lowest RB of the first sub-band and the offset #1.

[0195] For example, the second subband #1 corresponds to offset #1, where the first RB is the lowest RB of the first subband and the second RB is the lowest RB of the second subband. Then, the terminal 101 can determine the index of the lowest RB of the second subband by the sum of the index of the lowest RB of the first subband and the offset #1.

[0196] For example, the second subband #1 corresponds to offset #1, where the first RB is the highest RB of the first subband and the second RB is the lowest RB of the second subband. Then, the terminal 101 can determine the index of the lowest RB of the second subband by the sum of the index of the highest RB of the first subband and the offset #1.

[0197] For example, the second sub-band #1 corresponds to offset #1, where the first RB is the highest RB of the first sub-band and the second RB is the highest RB of the second sub-band. Then, the terminal 101 can determine the index of the highest RB of the second sub-band as the sum of the index of the highest RB of the first sub-band and the offset #1.

[0198] Of course, the first RB can be any RB in the first subband, and the second RB can be any RB in the second subband. For example, the first RB can be the third RB in the first subband, and the second RB can be the fourth RB in the second subband.

[0199] In cases 1-2, the number of second sub-bands is 2, and the number of offsets is 1.

[0200] The first RB can be any one of the lowest RB, highest RB, or specific RB of the first sub-band.

[0201] The second RB can be any one of the lowest RB, highest RB, or specific RB of the second sub-band.

[0202] For example, the second subband #1 and the second subband #2 correspond to offset #1. Here, the first RB is the lowest RB of the first subband, the second RB is the highest RB of the second subband #1, and the second subband #2 is the lowest RB. Then, the terminal 101 can determine the index of the highest RB of the second subband #1 by the sum of the index of the lowest RB of the first subband and the offset #1, and can determine the index of the lowest RB of the second subband #2 by the sum of the index of the lowest RB of the first subband and the offset #1.

[0203] In case 2-2, the number of the second sub-bands is the same as the number of offsets, both being 2.

[0204] In one example, the values ​​of the two offsets can be the same or different.

[0205] Based on the above correspondence, terminal 101 has determined the second sub-band corresponding to each offset. For example, offset #1 corresponds to second sub-band #1, offset #2 corresponds to second sub-band #2, and correspondingly, the second RB includes the lowest RB in second sub-band #1 and the highest RB in second sub-band #2. At this time, terminal 101 can determine the index of the lowest RB in second sub-band #1 based on the sum of the index of the first RB and offset #1. In addition, the index of the highest RB in second sub-band #2 can be determined based on the sum of the index of the first RB and offset #2.

[0206] The above is merely an example; this disclosure does not limit the method by which terminal 101 determines the second RB.

[0207] Furthermore, terminal 101 can determine the number of second RBs occupied by each second subband based on the number of first RBs and the total number of RBs.

[0208] Wherein, the number of first RBs is the number of RBs included in the first frequency domain resource, and the total number of RBs is the number of RBs included in the activated BWP.

[0209] Case 2-1: The number of the second sub-band is 1. In this case, the number of the second RB is equal to the difference between the total number of RBs and the number of the first RB.

[0210] For example, if the number of first RBs is 10 and the total number of RBs is 30, then the number of second RBs included in the second sub-band is 20.

[0211] In case 2-2, the number of second sub-bands is 2. At this time, the first sub-band is located in the middle of the active BWP. Then, the terminal 101 can determine the number of second RBs included in the second sub-band based on the total number of RBs, the number of first RBs, and the first frequency domain resource range.

[0212] For example, if the number of first RBs is 10 and the total number of RBs is 30, then the sum of the number of second RBs included in second subband #1 and second subband #2 is 20. Additionally, if the first frequency domain resources include RBs #12 to #21, then the number of second RBs included in second subband #1 is 12, and the number of second RBs included in second subband #2 is 8.

[0213] The above is merely an illustrative example, and this disclosure does not limit the method of determining the number of second RBs.

[0214] Furthermore, terminal 101 can jointly determine the second frequency domain resources based on the second RB and the number of the second RB.

[0215] For example, if the number of second subbands is 1, the number of first RBs is 10, the number of second RBs is 20, the offset #1 is 1, the first RB is the highest RB in the first subband, and the second RB is the lowest RB in the second subband. If the index of the first RB is 9, then the second frequency domain resources occupied by the second subband include RB#10 to RB#29.

[0216] For example, if the number of second subbands is 2, the number of second RBs included in second subband #1 is 12, the offset #1 corresponding to second subband #1 is 1, the first RB is the lowest RB of the first subband, specifically RB#12, and the second RB is the highest RB of second subband #1, then the second frequency domain resources specifically occupied by second subband #1 are RB#0 to RB#11.

[0217] The number of second RBs included in the second sub-band #2 is 8, and the offset #2 corresponding to the second sub-band #2 is also 1. The first RB is the highest RB of the first sub-band, such as RB#21, and the second RB is the lowest RB of the second sub-band #2. Therefore, the second frequency domain resources specifically occupied by the second sub-band #2 include RB#22 to RB#29.

[0218] The above is merely an illustrative example, and this disclosure does not limit the method by which the terminal 101 determines the second frequency domain resources occupied by the second sub-band.

[0219] In step S2112, network device 102 determines the second frequency domain resource based on the first frequency domain resource and the offset.

[0220] In some embodiments, the network device 102 determines the second frequency domain resources in a similar manner to the terminal 101, and will not be described again here.

[0312] In the above embodiments, the network device does not need to configure the starting RB index and the number of RBs included in the second subband through signaling, which reduces the signaling overhead of subband configuration and improves the feasibility and reliability of subband full-duplex communication.

[0313] The above process is further illustrated with examples below.

[0314] In this embodiment of the disclosure, when determining the frequency domain resources of the second SBFD subband, the terminal network device uses the frequency domain resources of the first SBFD subband as a reference and determines the frequency domain resources occupied by the second SBFD subband through a configured or predefined offset value.

[0315] Terminal side:

[0316] On the SBFD symbol, the terminal uses the first subband as a reference to determine the frequency domain resources of the second subband.

[0317] Method 1: The terminal uses the lowest number RB and / or the highest number RB of the first subband as reference points, and determines the highest number RB and / or the highest number RB of the second subband according to the offset indicated by the base station.

[0318] The terminal determines the RB actually occupied by the second subband based on the frequency domain resources occupied by the first subband, the offset between the first subband and the second subband, and the RBs contained in the active BWP.

[0319] The active BWP is a BWP aligned with the direction of the second subband. For example, if the second subband is a DL subband, then the active BWP is an active DL BWP.

[0320] The terminal receives one or more offsets configured by the base station.

[0321] When the base station is configured with multiple offsets, the values ​​of the multiple offsets may be the same or different.

[0322] When the base station is configured with multiple offsets, the multiple offset values ​​and the frequency offset positions they indicate are determined by any of the following methods.

[0323] The predefined method, that is, the first offset in the offset value list is used to indicate the number of RBs between the lowest RB of the first subband and the highest RB of the second subband #1, and the second offset in the offset value list is used to indicate the number of RBs between the highest RB of the first subband and the lowest RB of the second subband #2.

[0324] When the terminal receives only one offset configured by the network side, and the base station configures two second subbands on the SBFD symbol, the lowest RB of the first subband and the highest RB of the first subband#1, as well as the RB between the highest RB of the UL subband and the lowest RB of the second subband#2, are determined by the offset.

[0325] The number of second subbands configured in network devices, such as base stations, can be determined by any of the following methods, without any limitation in this patent.

[0326] Method 1: The base station instructs the terminal on the number of its configured second subbands.

[0327] Method 2: The terminal determines the number of second subbands based on the frequency domain resource location occupied by the first subband within the active BWP. For example, if the first subband is on one side of the active BWP, there is only one second subband; if the first subband is in the middle of the active BWP, there are two second subbands.

[0328] Method 2: The terminal uses the lowest number RB and / or the highest number RB of the first subband as reference points, and determines the highest number RB and / or the highest number RB of the second subband according to a predefined offset.

[0329] The terminal determines the RBs actually occupied by the second subband based on the frequency domain resources occupied by the first subband, the offset between the first subband and the second subband, and the RBs contained in the active BWP.

[0330] The active BWP is a BWP aligned with the direction of the second subband. For example, if the second subband is a DL subband, then the active BWP is an active DL BWP.

[0331] The predefined method determines one or more offsets.

[0332] The multiple predefined offset values ​​are determined either through protocol predefinition or through terminal capability reporting.

[0333] The protocol is predefined in ways including determining based on carrier, band, SCS, BWP, etc.

[0334] The terminal capability reporting method is for the terminal to report one or more offsets it supports.

[0335] When the number of predefined offsets is greater than 1, the values ​​of the multiple offsets are the same or different.

[0336] The plurality of offset values ​​and the frequency offset positions they indicate are determined by any of the following methods.

[0337] The predefined method, that is, the first offset in the offset value list is used to indicate the number of RBs between the lowest RB of the first subband and the highest RB of the second subband #1, and the second offset in the offset value list is used to indicate the number of RBs between the highest RB of the first subband and the lowest RB of the second subband #2.

[0338] When the terminal receives only one offset configured by the network side, and the base station configures two second subbands on the SBFD symbol, the lowest RB of the first subband and the highest RB of the first subband#1, as well as the RB between the highest RB of the UL subband and the lowest RB of the second subband#2, are determined by the offset.

[0345] The base station determines the RBs actually occupied by the second subband based on the frequency domain resources occupied by the first subband, the offset between the first subband and the second subband, and the RBs contained in the active BWP.

[0346] The active BWP is a BWP aligned with the direction of the second subband. For example, if the second subband is a DL subband, then the active BWP is an active DL BWP.

[0347] The base station configures one or more offsets for the terminal.

[0351] When the terminal receives only one offset configured by the network side, and the base station configures two second subbands on the SBFD symbol, the lowest RB of the first subband and the highest RB of the first subband#1, as well as the RB between the highest RB of the UL subband and the lowest RB of the second subband#2, are determined by the offset.

[0356] The base station determines the RBs actually occupied by the second subband based on the frequency domain resources occupied by the first subband, the offset between the first subband and the second subband, and the RBs contained in the active BWP.

[0357] The active BWP is a BWP aligned with the direction of the second subband. For example, if the second subband is a DL subband, then the active BWP is an active DL BWP.

[0365] When the network side configures an offset and the base station configures two second subbands on the SBFD symbol, the lowest RB of the first subband and the highest RB of the first subband#1, as well as the RB interval between the highest RB of the UL subband and the lowest RB of the second subband#2, are determined by the offset.
