Detailed Implementation

[0013] The method disclosed herein can be used to solve the problem of "resource mapping during downlink transmission and / or reception".

[0014] This disclosure presents a resource determination method and apparatus, a communication device, a communication system, and a storage medium. In a first aspect, embodiments of this disclosure propose a resource determination method, the method comprising: The device receives first information and second information sent by a network device, wherein the first information is used to indicate a frequency domain range that cannot be used for downlink transmission and / or reception, and the second information is used to indicate a first resource allocated by the network device for the terminal. Based on the first and second information, a second resource for downlink transmission and / or reception in the sub-band full-duplex SBFD time slot is determined.

[0015] In the above embodiments, the terminal receives first information and second information sent by the network device; based on the first information and second information, it determines the second resource in the sub-band full-duplex SBFD time unit for downlink transmission and / or reception, so as to solve the resource mapping problem in the downlink transmission and / or reception process and improve resource mapping efficiency and communication efficiency.

[0016] In conjunction with some embodiments of the first aspect, in some embodiments, the first resource is one or more resource block groups (RBGs), and the method further includes: Receive third information sent by the network device; the third information is used to configure RBG. Based on the bandwidth information of the partial bandwidth BWP, the starting position of the BWP, and the third information, determine the number of VRBs contained in each RBG within the frequency domain range of the BWP and the frequency domain range of each RBG.

[0017] In the above embodiments, by receiving third information sent by the network device and determining the number of VRBs contained in each RBG within the frequency domain range of the BWP and the frequency domain range of each RBG, the terminal can map all the VRBs in the RBG to PRBs used for downlink transmission and / or reception when the resource allocation mode is type 0. This solves the resource mapping problem in the downlink transmission and / or reception process and avoids some VRBs being mapped to PRBs that cannot be used for downlink transmission and / or reception.

[0018] In conjunction with some embodiments of the first aspect, in some embodiments, determining the second resource for downlink transmission and / or reception in the sub-band full-duplex SBFD time unit based on the first information and the second information includes: Based on the first information and the number of VRBs contained in each RBG within the frequency domain range of the BWP and the frequency domain range of each RBG, determine the virtual resource blocks (VRBs) in the first resource indicated by the second information that are used for downlink transmission and / or reception. The physical resource block (PRB) after the VRB is mapped non-interleaved is determined as the second resource.

[0019] In the example above, by determining the PRB after non-interleaving mapping as the second resource, it is possible to map all VRBs in the RBG to the PRBs used for downlink transmission and / or reception when the resource allocation method is type 0. This ensures the accuracy of resource mapping under different resource allocation methods and guarantees that the mapped resources can be used for downlink transmission and / or reception.

[0020] In conjunction with some embodiments of the first aspect, in some embodiments, the first resource is a consecutive plurality of VRBs, and based on the first information and the second information, determining the second resource for downlink transmission and / or reception in the subband full-duplex SBFD time unit includes: Based on the first information, within the frequency domain range of the BWP, the VRB for downlink transmission and / or reception in the first resource indicated by the second information is determined; The PRB after uninterleaved mapping of the VRB for downlink transmission and / or reception in the first resource indicated by the second information is determined as the second resource.

[0021] In the above embodiments, by determining the PRB after non-interleaved mapping of the VRB used for downlink transmission and / or reception as the second resource, it is possible to facilitate the terminal to map some or all of the continuous VRBs allocated by the network device to the PRBs used for downlink transmission and / or reception when the resource allocation method is type 1 and non-interleaved mapping method is used. This ensures the accuracy of resource mapping under different resource allocation methods and different mapping methods, and ensures that the mapped resources can be used for downlink transmission and / or reception, avoiding some VRBs being mapped to PRBs that cannot be used for downlink transmission and / or reception.

[0022] In conjunction with some embodiments of the first aspect, in some embodiments, the first resource is a consecutive plurality of VRBs, and the method further includes: Receive the fourth information sent by the network device; the fourth information is used for interleaving configuration. Based on the bandwidth information of the BWP, the starting position of the BWP, and the fourth information, determine the number of first VRBs included in each VRB bundle within the frequency domain range of the BWP and the first frequency domain range of each VRB bundle. Based on the bandwidth information of the BWP, the starting position of the BWP, and the fourth information, determine the number of PRBs contained in each PRB bundle within the frequency domain range of the BWP and the frequency domain range of each PRB bundle. The division method of PRB bundles and VRB bundles is the same.

[0023] In the above embodiments, by receiving the fourth information, the number and frequency range of VRB and PRB bundles within the BWP range are determined, thereby reducing the mapping complexity when the resource allocation method is type 1 and the interleaving mapping method is used, by using VRB bundles and PRB bundles for resource mapping.

[0024] In conjunction with some embodiments of the first aspect, in some embodiments, determining the second resource for downlink transmission and / or reception in the sub-band full-duplex SBFD time unit based on the first information and the second information includes: Based on the first information, the number of first VRBs included in each VRB bundle, and the first frequency domain range of each VRB bundle, in each frequency domain range available for downlink transmission and / or reception in the BWP, the number of second VRBs and the second frequency domain range included in the VRB bundle available for downlink transmission and / or reception in the first resource indicated by the second information are determined, wherein the number of second VRBs is less than or equal to the number of first VRBs, and the second frequency domain range is the same as or a subset of the first frequency domain range; Identify the VRB bundle after interleaving mapping in the first resource indicated by the second information, which can be used for downlink transmission and / or reception, and use the PRB in the PRB bundle as the second resource.

[0025] In the above embodiments, by determining the number of second VRBs and the second frequency domain range included in the VRB bundles that can be used for downlink transmission and / or reception, the PRB bundles after interleaving and mapping of the VRB bundles that can be used for downlink transmission and / or reception in the first resource indicated by the second information are determined. The PRBs in the PRB bundles are used as the second resource. This enables the mapping of VRB bundles to PRB bundles used for downlink transmission and / or reception when the resource allocation method is type 1 and the interleaving mapping method is used. This ensures the accuracy of resource mapping under different resource allocation methods and different mapping methods, and ensures that the mapped resources can be used for downlink transmission and / or reception. It also avoids some VRB bundles being mapped to PRB bundles that cannot be used for downlink transmission and / or reception.

[0026] In conjunction with some embodiments of the first aspect, in some embodiments, a fifth message sent by a network device is received, wherein the fifth message is used to instruct the terminal to use interleaved mapping or non-interleaved mapping.

[0027] In the above embodiments, by receiving the fifth information, the mapping method used when mapping VRB to PRB can be determined, so that different resource mapping rules can be used to map VRB to PRB that can be used for downlink transmission and / or reception according to different mapping methods, and the mapped resources can all be used for downlink transmission and / or reception.

[0028] In conjunction with some embodiments of the first aspect, in some embodiments, a second resource is used to receive downlink data or a channel.

[0029] In the above embodiments, by utilizing the second resource to receive downlink data or channels, since the second resource can be used for downlink transmission and / or reception, downlink transmission problems caused by some VRBs being mapped to PRBs that cannot be used for downlink transmission and / or reception are avoided, thereby enhancing the stability of the communication system.

[0030] In conjunction with some embodiments of the first aspect, in some embodiments, frequency domain ranges that cannot be used for downlink transmission and / or reception include: The frequency domain range of the uplink subband; or the frequency domain range of the uplink subband and the guard band.

[0031] In the above embodiments, the frequency range that cannot be used for downlink transmission and / or reception can be determined according to communication requirements, enhancing the flexibility of the communication system. By defining the guard band as the frequency range that can be used for downlink transmission and / or reception, the frequency range for downlink transmission and / or reception is increased, thereby improving the efficiency of downlink transmission and / or reception.

[0032] Secondly, embodiments of this disclosure propose a resource determination method, including: Send first information and second information to the terminal, wherein the first information is used to indicate the frequency domain range that cannot be used for downlink transmission and / or reception, the second information is used to indicate the first resource allocated by the network device to the terminal, and the first information and the second information are used to assist the terminal in determining the second resource in the sub-band full-duplex SBFD time unit for downlink transmission and / or reception.

[0033] In the above embodiments, the network device can send first information and second information to the terminal to solve the resource mapping problem in the downlink transmission and / or reception process, and improve resource mapping efficiency and communication efficiency.

[0034] In conjunction with some embodiments of the second aspect, in some embodiments, the first resource is one or more resource block groups (RBGs), and the method further includes: The terminal sends third information, which is used to configure RBGs. The third information is used to assist the terminal in determining the number of VRBs contained in each RBG within the frequency domain range of the BWP and the frequency domain range of each RBG. The number of VRBs and the frequency domain range are determined by the terminal based on the bandwidth information of the BWP, the starting position of the BWP, and the third information.

[0035] In the above embodiments, the network device can send third information to the terminal so that the terminal can determine the number of VRBs contained in each RBG within the frequency domain range of the BWP and the frequency domain range of each RBG, so as to determine the second resource used for downlink transmission and / or reception in the subband full-duplex SBFD time unit. This allows the terminal to map all VRBs in the RBG to PRBs used for downlink transmission and / or reception when the resource allocation mode is type 0, thus solving the resource mapping problem in the downlink transmission and / or reception process and avoiding some VRBs being mapped to PRBs that cannot be used for downlink transmission and / or reception.

[0036] In conjunction with some embodiments of the second aspect, in some embodiments, the second resource is the physical resource block (PRB) after the virtual resource block (VRB) is non-interleaved mapped by the terminal. The VRB is determined by the terminal based on the first information and the number of VRBs contained in each RBG within the frequency domain range of the BWP and the frequency domain range of each RBG. The VRB is the VRB used for downlink transmission and / or reception in the first resource indicated by the second information.

[0037] In the above embodiments, by determining the PRB after non-interleaving mapping as the second resource, the terminal can map all the VRBs in the RBG to the PRBs used for downlink transmission and / or reception when the resource allocation method is type 0. This ensures the accuracy of resource mapping under different resource allocation methods and guarantees that the mapped resources can be used for downlink transmission and / or reception.

[0038] In conjunction with some embodiments of the second aspect, in some embodiments, the first resource is a series of consecutive VRBs, the second resource is a PRB after non-interleaved mapping of VRBs determined by the terminal, the VRBs are determined by the terminal in the frequency domain range of the BWP based on the first information, and the VRBs are VRBs in the first resource indicated by the second information that are used for downlink transmission and / or reception.

[0039] In the above embodiments, by determining the PRB after non-interleaved mapping of the VRB used for downlink transmission and / or reception as the second resource, it is possible to facilitate the terminal to map some or all of the continuous VRBs allocated by the network device to the PRBs used for downlink transmission and / or reception when the resource allocation method is type 1 and non-interleaved mapping method is used. This ensures the accuracy of resource mapping under different resource allocation methods and different mapping methods, and ensures that the mapped resources can be used for downlink transmission and / or reception, avoiding some VRBs being mapped to PRBs that cannot be used for downlink transmission and / or reception.

[0040] In conjunction with some embodiments of the second aspect, in some embodiments, the first resource is a consecutive plurality of VRBs, and the method further includes: The terminal sends a fourth piece of information. This fourth piece of information is used for interleaving configuration. It assists the terminal in determining the number of first VRBs included in each VRB bundle within the frequency domain range of the BWP and the first frequency domain range of each VRB bundle. The number of VRBs and the first frequency domain range are determined by the terminal based on the bandwidth information of the BWP, the starting position of the BWP, and the fourth piece of information. The fourth piece of information is also used to assist the terminal in determining the number of PRBs included in each PRB bundle within the frequency domain range of the BWP and the frequency domain range of each PRB bundle. The number of PRBs and the frequency domain range are determined by the terminal based on the bandwidth information of the BWP, the starting position of the BWP, and the fourth piece of information. The division method of PRB bundles and VRB bundles is the same.

[0041] In the above embodiments, by sending fourth information to the terminal, the number and frequency range of VRB and PRB bundles within the BWP range are determined, thereby reducing the mapping complexity when resource allocation is of type 1 and interleaving mapping is used, by using VRB bundling and PRB bundling for resource mapping.

[0042] In conjunction with some embodiments of the second aspect, in some embodiments, the second resource is a PRB in the PRB bundle after interleaving and mapping of VRB bundles that can be used for downlink transmission and / or reception in the first resource indicated by the second information determined by the terminal. The number of second VRBs and the second frequency domain range contained in the VRB bundles that can be used for downlink transmission and / or reception in the first resource indicated by the second information are determined by the terminal based on the first information, the number of first VRBs contained in each VRB bundle, and the first frequency domain range of each VRB bundle, in each frequency domain range that can be used for downlink transmission and / or reception in the BWP. The number of second VRBs is less than or equal to the number of first VRBs, and the second frequency domain range is the same as or a subset of the first frequency domain range.

[0043] In the above embodiments, by determining the number of second VRBs and the second frequency domain range included in the VRB bundles that can be used for downlink transmission and / or reception, the PRB bundles after interleaving and mapping of the VRB bundles that can be used for downlink transmission and / or reception in the first resource indicated by the second information are determined. The PRBs in the PRB bundles are used as the second resource. This enables the mapping of VRB bundles to PRB bundles used for downlink transmission and / or reception when the resource allocation method is type 1 and the interleaving mapping method is used. This ensures the accuracy of resource mapping under different resource allocation methods and different mapping methods, and ensures that the mapped resources can be used for downlink transmission and / or reception. It also avoids some VRB bundles being mapped to PRB bundles that cannot be used for downlink transmission and / or reception.

[0044] In conjunction with some embodiments of the second aspect, in some embodiments, the method further includes: A fifth message is sent to the terminal, which instructs the terminal to use either interleaved or non-interleaved mapping.

[0060] Figure 1 This is a schematic diagram of the architecture of a communication system according to embodiments of this disclosure. Figure 1 As shown, the communication system 100 may include a terminal 101 and a network device 102. The network device 102 may include at least one of an access network device and a core network device. 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. 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), wireless 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 wireless fidelity (WiFi) system. 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 internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs. 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. In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0061] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0062] The following embodiments of this disclosure can be applied to Figure 1 The communication system 100 shown, or a part thereof, but not limited to it. Figure 1 The entities shown are illustrative; a communication system may include... Figure 1 All or part of the main body, or may include Figure 1 Other entities besides the main body, the number and form of each entity are arbitrary, the connection relationship between the entities is illustrative, the entities may not be connected or may be connected, and the connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection. The embodiments disclosed herein can be applied to resource mapping of PDSCH in SBFD scenarios.

[0063] Specifically, a carrier component is divided into multiple sub-bands in the frequency domain on a downlink or flexible symbol. These multiple SBs include one uplink sub-band and at least one downlink (DL) sub-band. The base station can transmit DL signals in the DL sub-band and simultaneously receive UL signals in the UL sub-band. The DL or F symbol is configured as TDD-UL-DL-ConfigCommon or TDD-UL-DL-ConfigDedicated, or indicated as DL or F by DCI2-0. A symbol that simultaneously contains both the DL and UL sub-bands in the frequency domain can be called an SBFD symbol.

[0064] In addition, a guard band (GB) may exist between the DL subband and the UL subband to reduce interference between DL signals in the DL subband and UL signals in the UL subband through frequency domain isolation. In the SBFD symbol, the frequency range available for DL ​​transmission and / or reception may be discontinuous; one possibility is that the GB and UL subbands cannot be used for DL ​​transmission and / or reception.

[0065] Optionally, there are two frequency domain resource allocation schemes for PDSCH transmission and / or reception: The frequency domain resource allocation (FDRA) of the Physical Downlink Shared Channel (PDSCH) of Type 0 is indicated by a bitmap, which indicates the RBG used. Each RBG contains one or more VRBs, and the VRBs are mapped to PRBs in a non-interleaved mapping manner.

[0066] Type 1 PDSCH FDRA indicates the consecutive VRBs used through Resource Indication Value (RIV), mapping VRBs to PRBs in an interleaved or non-interleaved manner.

[0067] Figure 2a This is an interactive schematic diagram illustrating a resource determination method according to embodiments of this disclosure. For example... Figure 2a As shown, this disclosure relates to a resource determination method for a communication system 100, the method comprising: Step 2101: Network device 102 sends first information and second information to terminal 101.

[0068] In some embodiments, terminal 101 may receive first information and second information.

[0069] In some embodiments, terminal 101 may receive first information and second information sent by network device 102.

[0070] In some embodiments, the first information may be used to indicate frequency domain ranges that are not available for downlink transmission and / or reception.

[0071] In some embodiments, the frequency domain range that cannot be used for downlink transmission and / or reception may include at least one of the frequency domain range of the uplink subband and the frequency domain range of the guard band. For example, the frequency domain range that cannot be used for downlink transmission and / or reception may be the frequency domain range of the uplink subband, or it may be the frequency domain range of both the uplink subband and the guard band.

[0072] In some embodiments, the first information may be used to indicate the frequency domain range available for downlink transmission and / or reception.

[0073] In some embodiments, the frequency domain range available for downlink transmission and / or reception may include at least one of the frequency domain range of the downlink subband and the frequency domain range of the guard band. For example, the frequency domain range available for downlink transmission and / or reception may be the frequency domain range of the downlink subband, or it may be the frequency domain range of both the downlink subband and the guard band.

[0074] In some embodiments, the name of the first information is not limited in this disclosure; it may be, for example, "non-downlink frequency domain range".

[0075] In some embodiments, the second information may be used to indicate the first resource allocated (or scheduled) by the network device for the terminal.

[0076] In some embodiments, the first resource may be a resource block group (RBG).

[0077] For example, in the case of type 0 frequency domain resource allocation, a network device can allocate RBGs to terminals. For Type 0 PDSCH (Frequency Domain Resource Allocation) (FDRA), the network device can indicate the RBGs to be used using a bitmap, where each RBG includes one or more VRBs. During resource mapping, VRBs can be mapped to PRBs using a non-interleaved mapping method.

[0078] In some embodiments, the name of the second information is not limited in this disclosure, and it may be, for example, "resource information", "resource block group information", etc.

[0079] In some embodiments, the network device can send first information and second information to the terminal by sending messages or signaling. For example, network device 102 sends first signaling, which may include indication information of frequency domain ranges that are unavailable for downlink transmission and / or reception, and indication information of the network device allocating first resources to the terminal. Correspondingly, terminal 101 can receive the first signaling. This first signaling may be, for example, downlink control information (DCI) signaling, but is not limited to this; it may also be other signaling (such as radio resource control (RRC) signaling, etc.).

[0080] For example, in one alternative embodiment, the network device sends DCI signaling to the terminal, indicating the RBGs assigned to the UE through a bitmap in the DCI signaling. For example, if the bitmap in the DCI signaling is 0001110100100, then RBGs #3, 4, 5, 7, and 10 are indicated for downlink transmission and / or reception.

[0081] Step 2102: Network device 102 sends third information to terminal 101.

[0082] In some embodiments, terminal 101 may receive third information.

[0083] In some embodiments, terminal 101 may receive third information sent by network device 102.

[0084] In some embodiments, the third information is used to configure the RBG, wherein the RBG configuration may include RBG configuration 1 (RBGconfiguration#1), RBG configuration 2 (RBG configuration#2), and may also include other configuration types, which are not limited in this disclosure. The RBG configuration can assist the terminal in determining the RBG size.

[0085] In some embodiments, the third information is further used to assist the terminal in determining the number of VRBs and the frequency domain range. In some optional embodiments, the third information can be used to assist the terminal in determining the number of VRBs contained in each RBG within the frequency domain range of a portion of the bandwidth BWP and the frequency domain range of each RBG. Specifically, the number of VRBs and the frequency domain range are determined by the terminal based on the bandwidth information of the BWP, the starting position of the BWP, and the third information.

[0086] In some embodiments, the name of the third information is not limited in this disclosure, and it may be, for example, “RBG configuration parameters” or “RBG configuration information”.

[0087] In some embodiments, the network device may send third information to the terminal by sending a message or signaling. For example, network device 102 sends a second signaling message, which may include the third information, namely, information for configuring the RBG. Correspondingly, terminal 101 may receive the second signaling message. This second signaling message may be, for example, DCI signaling, but is not limited to this; it may also be other signaling (such as RRC signaling).

[0088] For example, in some embodiments, the network device may send third information to the terminal, configuring RBG as configuration 1.

[0089] Step 2103: Terminal 101 determines the number of VRBs and the frequency domain range.

[0090] In some embodiments, the number of VRBs can be the number of VRBs contained in an RBG. Alternatively, the number of VRBs can be the number of VRBs contained in each RBG within the frequency domain range of the BWP.

[0091] In some embodiments, the frequency domain range may be the frequency domain range of the RBG. Alternatively, the frequency domain range may be the frequency domain range of each RBG within the frequency domain range of the BWP.

[0092] In some embodiments, terminal 101 may determine the number of VRBs contained in each RBG within the frequency domain range of BWP and the frequency domain range of each RBG.

[0093] In some embodiments, the terminal can determine the number of VRBs contained in each RBG within the frequency domain range of the BWP and the frequency domain range of each RBG based on the bandwidth information of the Bandwidth Part (BWP), the starting position of the BWP, and third information.

[0094] In some embodiments, terminal 101 can obtain the bandwidth information and starting position of the BWP. For example, terminal 101 can obtain the bandwidth information and starting position of the BWP from network device 102, which is not limited in this disclosure.

[0095] In some embodiments, the frequency domain range of the BWP can be determined using the bandwidth information and the starting position of the BWP. The starting position of the BWP can be the starting point of the BWP. Common Resource Block (CRB) .

[0096] In some embodiments, the terminal may first determine the number of VRBs contained in each RBG, and then determine the frequency domain range of each RBG. For example, the terminal may determine the number of VRBs contained in each RBG within the frequency domain range of the BWP based on the bandwidth information of the BWP and third information, and determine the frequency domain range of each RBG in conjunction with the starting position of the BWP.

[0097] In some embodiments, the terminal can simultaneously determine the number of VRBs contained in each RBG and the frequency domain range of each RBG. For example, the terminal can directly determine the number of VRBs contained in each RBG within the frequency domain range of the BWP and the frequency domain range of each RBG based on the bandwidth information of the BWP and third information, combined with the starting position of the BWP.

[0098] In some embodiments, a BWP can be understood as a contiguous RB resource in the frequency domain. The relevant configuration information of the BWP can be indicated by the network device, which may include the bandwidth information of the BWP, such as occupying 64 RBs. The relevant configuration information of the BWP may also include other information, such as sub-carrier space (SCS), etc., which will not be elaborated here. The relevant configuration information of the BWP can be configured through RRC signaling or other signaling, which will not be elaborated here.

[0099] For example, in one embodiment, the bandwidth of the BWP occupies 70 RBs. The terminal determines the RBG according to the BWP and related configurations. Assuming the RBG configuration information is RBG Configuration 1, the RGB configuration table is shown in Table 1 below. Based on the BWP bandwidth (i.e., the BWP size in Table 1 below), the size of the RBG can be determined to be 4 RBs.

[0100] Table 1 RGB Configuration Table

[0101] In some embodiments of this disclosure, the size of each RBG and the RBs it contains can be determined according to the following formula: (Equation 1) in, The number of RBGs One possible implementation is: This refers to the size of the BWP, i.e., the number of VRBs contained in the BWP. A BWP can be one of multiple BWPs configured on the terminal.

[0102] Another possible implementation is: It is the number of VRBs contained in the frequency domain range that can be used for DL ​​transmission in BWP. It is the index of the starting VRB in the CRB that can be used for DL ​​transfer in BWP.

[0103] Let P be the size of the RBG determined by Table 1 above, and mod represent the modulo operation. Then, the number of RBGs in the downlink subband can be determined. The size of the first RBG can be determined by the following formula: (Equation 2) in, Indicates the size of the first RGB, if The size of the last RBG can be determined by the following formula: (Equation 3) otherwise,

[0104] The size of the other RBGs is P.

[0105] Step 2104: Terminal 101 determines the second resource.

[0106] In some embodiments, the second resource may be a resource for downlink transmission and / or reception.

[0107] In some embodiments, the name of the second resource is not limited in this disclosure; it may be, for example, "downlink resource".

[0108] In some embodiments, terminal 101 may determine a second resource in the Subband Full Duplex (SBFD) time unit for downlink transmission and / or reception.

[0109] In some embodiments, the second resource is the physical resource block (PRB) after the virtual resource block (VRB) is non-interleaved and mapped by the terminal. The VRB is determined by the terminal based on the first information and the number of VRBs contained in each RBG within the frequency domain range of the BWP and the frequency domain range of each RBG. The VRB is the VRB in the first resource indicated by the second information that is used for downlink transmission and / or reception.

[0110] In some embodiments, an SBFD time unit may simultaneously include an uplink subband (UL Subband) and a downlink subband (DL Subband) in the frequency domain. In some optional embodiments, an SBFD time unit may also include a guard band (GB) in the frequency domain. In some optional embodiments, a time slot may be referred to as an SBFD time slot when at least one SBFD symbol exists among the multiple symbols included in a time slot.

[0111] In some embodiments, a “time unit” may be a “slot” or a “symbol”, which is not limited herein.

[0112] In some embodiments, the frequency domain resource allocation method is type 0. The terminal determines the second resource for downlink transmission and / or reception in the sub-band full-duplex SBFD time unit by: determining the virtual resource block (VRB) for downlink transmission and / or reception in the first resource indicated by the second information based on the first information and the number of VRBs contained in each RBG within the frequency domain range of the BWP and the frequency domain range of each RBG; and determining the physical resource block (PRB) after the non-interleaved mapping of the VRB as the second resource.

[0113] For example, the terminal can determine the VRBs available for downlink transmission and / or reception based on the number of VRBs contained in each RBG and the intersection of the frequency domain range of each RBG with the frequency domain range indicated by the first information.

[0114] For example, the network device indicates the RBG (i.e., the first resource) allocated to the UE via the bitmap in the DCI, such as 0001110100100, indicating that VRBs in RBG#3, 4, 5, 7, and 10 are used for transmission and / or reception. If the frequency domain range that cannot be used for downlink transmission and / or reception indicated in the first information is RBG#5, then the intersection RBG#5 cannot be used for downlink transmission and / or reception, and the VRBs in the remaining RBG#3, 4, 7, and 10 can be used for downlink transmission and / or reception.

[0115] For example, such as Figure 2bAs shown, the VRBs that overlap with the frequency ranges available for DL ​​transmission and / or reception in the RBG are the VRBs available for DL ​​transmission and / or reception. The PRBs after non-interleaving mapping of the VRBs available for DL ​​transmission and / or reception in the RBG allocated in the DCI are the PRBs for receiving DL transmission and / or reception. For example, if the GB and UL subbands cannot be used for DL ​​transmission and / or reception, and the scheduled RBGs include RBG#1, #2, #3, #4, #5, #6, #7, and #8, then the four VRBs in RBG#1, #2, and #3 are all VRBs available for DL ​​transmission and / or reception, the first VRB in RBG#4 is a VRB available for DL ​​transmission and / or reception, the last VRB in RBG#8 is a VRB available for DL ​​transmission and / or reception, and the number of VRBs available for DL ​​transmission and / or reception in RBG#5, #6, and #7 is 0.

[0116] In some embodiments, the terminal may determine the Physical Resource Block (PRB) after the VRB is mapped without interleaving, as a second resource. In other words, the terminal may perform resource mapping to map the VRB to the PRB, and the mapped PRB resource may be used for downlink transmission and / or reception, for example, it may be used to receive downlink data or channels.

[0117] For example, in one alternative embodiment, VRB Id#m is mapped to PRB Id#m, that is, if the bitmap in the DCI signaling received by the terminal indicates that VRB Id#0-m in RBG#n is used for DL ​​transmission and / or reception, then PRB Id#0-m is used for DL ​​transmission and / or reception, and the PRB used for DL ​​transmission and / or reception is a second resource.

[0118] Step 2105: Terminal 101 uses the second resource to receive downlink data or channel.

[0119] In some embodiments, the terminal utilizes the second resource to perform downlink reception, i.e., to receive downlink data or channels, so that the VRB can be fully mapped to the PRB used for DL ​​transmission and / or reception, thereby improving resource utilization efficiency.

[0120] The communication method involved in the embodiments of this disclosure may include at least one of steps 2101-2105. For example, step 2101 may be implemented as a standalone embodiment, step 2103 may be implemented as a standalone embodiment, steps 2101+2102+2104 may be implemented as standalone embodiments, and steps 2101+2102+2103 may be implemented as standalone embodiments, but are not limited thereto. In some embodiments, steps 2101 and 2102 may be performed in an interchangeable order or simultaneously. In some embodiments, steps 2102, 2103, 2104 and 2105 are optional, and one or more of these steps may be omitted or substituted in different embodiments. In some embodiments, the execution order of steps 2102 and 2103 may be before step 2104; the execution order of steps 2102 and 2103 may be before or after step 2101 or simultaneously with step 2101, and this disclosure does not limit this.

[0121] Optionally, this embodiment of the present disclosure can be applied to scenarios where the frequency domain resource allocation method is type 0 (i.e., Type 0 PDSCH FDRA). The present disclosure does not limit other possible applicable scenarios.

[0122] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.

[0123] Figure 2c This is an interactive schematic diagram illustrating a resource determination method according to embodiments of this disclosure. For example... Figure 2c As shown, this disclosure relates to a resource determination method for a communication system 100, the method comprising: Step 2201: Network device 102 sends first information and second information to terminal 101.

[0124] In some embodiments, the second information may be used to indicate the first resource allocated (or scheduled) by the network device for the terminal.

[0125] In some embodiments, the first resource may be a contiguous plurality of VRBs.

[0126] For example, in the case of type 1 frequency domain resource allocation, a network device can allocate multiple consecutive VRBs to a terminal. For Type 1 PDSCH FDRA, the network device can indicate a Resource Indication Value (RIV) through the FDRA field included in the DCI. The RIV can be used to indicate a contiguous segment of VRB resources. During resource mapping, VRBs can be mapped to PRBs using a non-interleaved mapping method.

[0127] For example, in one alternative embodiment, the network device sends DCI signaling to the terminal, where the FDRA field in the DCI indicates that the RIV indicates a continuous VRB resource VRB#2-22, thus indicating that VRB#2-22 is used for downlink transmission and / or reception.

[0128] For optional implementations of step 2201, please refer to [link / reference]. Figure 2a Optional implementation methods of step S2101, and Figure 2a Other related parts in the embodiments involved will not be described in detail here.

[0129] Step 2202: Network device 102 sends the fifth information to terminal 101.

[0130] In some embodiments, terminal 101 may receive fifth information.

[0131] In some embodiments, terminal 101 may receive fifth information sent by network device 102.

[0132] In some embodiments, the fifth information is used to indicate whether the terminal employs interleaved mapping or non-interleaved mapping. In other words, the fifth information is used to indicate a resource mapping method, which includes interleaved mapping and non-interleaved mapping. In other words, the fifth information is used to indicate a method of mapping a VRB to a PRB, wherein the VRB can be interleaved to a PRB, or the VRB can be non-interleaved to a PRB.

[0133] For example, the terminal can use non-interleaved mapping to map VRB#2-5 to PRB#2-5 respectively; the terminal can use interleaved mapping to map VRB bundle #1 to PRB bundle #5 according to certain interleaved mapping rules, such as... Figure 2d As shown.

[0134] In some embodiments, the name of the fifth information is not limited in this disclosure; it may be, for example, “interleaving instruction information” or “interleaving configuration information”.

[0135] In some embodiments, the network device may send fifth information to the terminal by sending a message or signaling. For example, network device 102 sends third signaling, which may include the fifth information, i.e., information indicating whether the terminal uses interleaved or non-interleaved mapping. Correspondingly, terminal 101 may receive the third signaling. This third signaling may be, for example, DCI signaling, but is not limited to this; it may also be other signaling (such as RRC signaling).

[0136] For example, in some alternative embodiments, the network device may send a fifth message to the terminal to instruct the terminal to use non-interleaved mapping. In some alternative embodiments, the network device may send a fifth message to the terminal to instruct the terminal to use interleaved mapping.

[0137] Step 2203: Terminal 101 determines the second resource.

[0138] In some embodiments, the second resource is the PRB after the VRB is uninterleaved and mapped by the terminal. The VRB is determined by the terminal in the frequency domain range of the BWP based on the first information. The VRB is the VRB used for downlink transmission and / or reception in the first resource indicated by the second information.

[0139] In some embodiments, the frequency domain resource allocation method is type 1, and the terminal determines the second resource for downlink transmission and / or reception in the sub-band full-duplex SBFD time unit by: based on the first information, determining the VRB for downlink transmission and / or reception in the first resource indicated by the second information within the frequency domain range of the BWP; and determining the PRB after the uninterleaved mapping of the VRB for downlink transmission and / or reception in the first resource indicated by the second information as the second resource.

[0140] In some embodiments, the terminal can determine, based on the first information, the VRBs (Vibration Zone Blocks) within the frequency domain range of the BWP (Band of Power) indicated by the second information for use in downlink transmission and / or reception in the first resource. For example, the network device indicates consecutive VRBs (i.e., the first resource) allocated to the UE via the RIV (Resource Information) in the DCI (Digital Interface Code), such as VRB#2-22. If the frequency domain range indicated in the first information as unusable for downlink transmission and / or reception is VRB#9-15, then the intersection VRB#9-15 is unusable for downlink transmission and / or reception, and the remaining VRBs#2-8 and VRB#16-22 are usable for downlink transmission and / or reception.

[0141] In some embodiments, the terminal determines the PRB after uninterleaved mapping of VRB as a second resource to receive downlink data or channels. For example, in the example above, the PRBs after uninterleaved mapping of VRB#2-8 and VRB#16-22 are PRB#2-8 and PRB#16-22, respectively, and PRB#2-8 and PRB#16-22 can be used as second resources for downlink transmission and / or reception.

[0142] For example, in one alternative embodiment, VRB Id#m is mapped to PRB Id#m, that is, if the RIV in the DCI signaling received by the terminal indicates that VRB Id#m is used for DL ​​transmission and / or reception, then PRB Id#m is used for DL ​​transmission and / or reception, and the PRB used for DL ​​transmission and / or reception is a second resource.

[0143] For optional implementations of step 2203, please refer to [link / reference]. Figure 2a Optional implementation methods of step S2104, and Figure 2a Other related parts in the embodiments involved will not be described in detail here.

[0144] Step 2204: Terminal 101 uses the second resource to receive downlink data or channel.

[0145] For optional implementations of step 2204, please refer to [link / reference]. Figure 2a Optional implementation methods of step S2105, and Figure 2a Other related parts in the embodiments involved will not be described in detail here.

[0146] In some embodiments, the terminal utilizes a second resource for receiving, i.e., receiving downlink data or channels, so that the VRB can be fully mapped to the PRB used for DL ​​transmission and / or reception, thereby improving resource utilization efficiency.

[0147] The communication method involved in the embodiments of this disclosure may include at least one of steps 2201-2204. For example, step 2201 may be implemented as a standalone embodiment, step 2203 may be implemented as a standalone embodiment, steps 2201+2202+2204 may be implemented as standalone embodiments, and steps 2201+2202+2203 may be implemented as standalone embodiments, but are not limited thereto. In some embodiments, steps 2201 and 2202 may be performed in an alternate order or simultaneously. In some embodiments, steps 2202, 2203, and 2204 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0148] In some embodiments, the execution order of step 2202 may be before step 2203; the execution order of step 2202 may be before or after step 2201 or simultaneously with step 2201, and this disclosure does not limit this.

[0149] Optionally, this embodiment of the present disclosure can be applied to scenarios where the frequency domain resource allocation method is type 1 (i.e., Type 1 PDSCH FDRA), using a non-interleaved mapping method. The present disclosure does not limit other possible applicable scenarios. In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.

[0150] Figure 2e This is an interactive schematic diagram illustrating a resource determination method according to embodiments of this disclosure. For example... Figure 2e As shown, this disclosure relates to a resource determination method for a communication system 100, the method comprising: Step 2301: Network device 102 sends first information and second information to terminal 101.

[0151] In some embodiments, the second information may be used to indicate the first resource allocated (or scheduled) by the network device for the terminal.

[0152] In some embodiments, the first resource may be a contiguous plurality of VRBs.

[0153] For example, in the case of type 1 frequency domain resource allocation, a network device can allocate multiple consecutive VRBs to a terminal. For Type 1 PDSCH FDRA, the network device can indicate a Resource Indication Value (RIV) through the FDRA field included in the DCI. The RIV can be used to indicate a contiguous segment of VRB resources. During resource mapping, VRBs can be mapped to PRBs through interleaving mapping.

[0155] Step 2302: Terminal 101 receives the fifth message sent by network device 102.

[0156] In some embodiments, the terminal may employ interleaving mapping to map VRB#2-5 to PRB#2-5 respectively; the terminal may employ interleaving mapping to map VRB bundle #1 to PRB bundle #5 according to certain interleaving mapping rules, such as... Figure 2d As shown.

[0157] For optional implementations of step 2302, please refer to [link / reference]. Figure 2b Optional implementation methods for step 2202, and Figure 2c Other related parts in the embodiments involved will not be described in detail here.

[0158] Step 2303: Network device 102 sends the fourth information to terminal 101.

[0159] In some embodiments, terminal 101 may receive fourth information.

[0160] In some embodiments, terminal 101 may receive fourth information sent by network device 102.

[0161] In some embodiments, the frequency domain resource allocation method is type 1, and under the interleaving mapping method, the terminal 101 can receive the fourth information sent by the network device 102.

[0162] In some embodiments, the fourth information can be used for interleaving configuration. In other words, the fourth information can be used to indicate the rules for interleaving configuration.

[0163] In some embodiments, the fourth information is used to assist the terminal in determining the number of first VRBs included in each VRB bundle within the frequency domain range of the BWP and the first frequency domain range of each VRB bundle. The number of VRBs and the first frequency domain range are determined by the terminal based on the bandwidth information of the BWP, the starting position of the BWP, and the fourth information. In some embodiments, the fourth information is also used to assist the terminal in determining the number of PRBs included in each PRB bundle within the frequency domain range of the BWP and the frequency domain range of each PRB bundle. The number of PRBs and the frequency domain range are determined by the terminal based on the bandwidth information of the BWP, the starting position of the BWP, and the fourth information. The division method of PRB bundles and VRB bundles is the same.

[0164] In some embodiments, the name of the fourth information is not limited in this disclosure, and it may be, for example, “interleaving information”, “interleaving configuration information”, “interleaving configuration parameters”, etc.

[0165] In some embodiments, the fourth piece of information may be the VRBToPRB-Interleaver parameter.

[0166] In some embodiments, the network device may send fourth information to the terminal by sending a message or signaling. For example, network device 102 sends fourth signaling, which may include fourth information, i.e., information for interleaving configuration indicated by the network device. Correspondingly, terminal 101 may receive the fourth signaling, which may be, for example, DCI signaling, but is not limited to this, and may also be other signaling (such as RRC signaling, etc.).

[0167] Step 2304: Terminal 101 determines the number of VRBs and the frequency domain range.

[0168] In some embodiments, the number of VRBs can be the number of VRBs included in each VRB bundle within the frequency domain range of the BWP. Alternatively, the number of VRBs can be the number of VRBs included in each VRB bundle within the frequency domain range of the BWP.

[0169] In some embodiments, the frequency domain range may be the frequency domain range of the VRB bundle. Alternatively, the frequency domain range may be the frequency domain range of each VRB bundle within the frequency domain range of the BWP.

[0170] In some embodiments, terminal 101 determines the number of first VRBs included in each VRB bundle within the frequency domain range of the BWP and the first frequency domain range of each VRB bundle.

[0171] In some embodiments, the terminal can determine the number of first VRBs included in each VRB bundle within the frequency domain range of the BWP and the first frequency domain range of each VRB bundle based on the bandwidth information of the BWP, the starting position of the BWP, and the fourth information. In some embodiments, the terminal 101 can obtain the bandwidth information of the BWP and the starting position of the BWP. For example, the terminal 101 can obtain the bandwidth information of the BWP and the starting position of the BWP from the network device 102, which is not limited in this disclosure.

[0172] In some embodiments, the frequency domain range of the BWP can be determined using the bandwidth information and the starting position of the BWP. The starting position of the BWP can be the index of the starting VRB of the BWP within the CRB.

[0173] In some embodiments, a BWP can be understood as a contiguous RB resource in the frequency domain. The relevant configuration information of the BWP can be indicated by the network device, which may include the bandwidth information of the BWP, such as occupying 64 RBs. The relevant configuration information of the BWP may also include other information, such as sub-carrier space (SCS), etc., which will not be elaborated here. The relevant configuration information of the BWP can be configured through RRC signaling or other signaling, which will not be elaborated here.

[0174] In some alternative embodiments, terminal 101 may determine the number of first VRBs included in each VRB bundle within the frequency domain range of the BWP and the first frequency domain range of each VRB bundle.

[0175] For example, the terminal can determine VRB bundling within the frequency domain range of the BWP, and the number of VRB bundles is... There are 1, 1, ..., 1, ... -1}.

[0176] In some embodiments of this disclosure, the number and size of VRB bundles within the frequency domain of the BWP can be determined according to the following formula: (Equation 4) in, The number of VRBs bundled within the BWP frequency domain range. The number of VRBs in the BWP frequency domain range. Let L be the index of the starting VRB in the CRB within the BWP frequency domain, L be the size of the VRB bundle, and mod represent the modulo operation. Then, the number of VRB bundles within the BWP frequency domain can be determined. The size of the first VRB bundle can be calculated using the following formula: (Equation 5) in, This indicates the size of the first VRB bundle within the BWP frequency domain. The size of the last VRB bundle within the BWP frequency domain can be calculated using the following formula: (Equation 6) otherwise, .

[0177] The size of other VRB bundles within the BWP frequency domain is .

[0178] In some alternative embodiments, in the SBFD time unit, the frequency domain range H of BWP overlaps with two discontinuous downlink sub-bands and one uplink sub-band. That is, the frequency domain range of BWP may include a third frequency domain range (frequency domain range 1, for example, the frequency domain range of the first downlink sub-band and the frequency domain range overlapping with BWP) and a fourth frequency domain range (frequency domain range 2, for example, the frequency domain range of the second downlink sub-band and the frequency domain range overlapping with BWP). Terminal 101 can determine the number of VRBs included in each VRB bundle in the third frequency domain range and the frequency domain range of each VRB bundle, respectively.

[0179] In some embodiments, the number of VRBs can be the number of VRBs included in each VRB bundle within the third / fourth frequency domain range of the BWP's frequency domain range. Optionally, the number of VRBs can be the number of VRBs included in each VRB bundle within the third / fourth frequency domain range.

[0180] In some embodiments, the frequency domain range may be the frequency domain range bundled with VRBs. Alternatively, the frequency domain range may be the frequency domain range bundled with each VRB within a third / fourth frequency domain range.

[0181] In some embodiments, terminal 101 may determine the number of first VRBs included in each VRB bundle within each frequency range of the BWP and the first frequency range of each VRB bundle. In other words, terminal 101 may determine the number of VRBs included in each VRB bundle within the third frequency range and the frequency range of each VRB bundle within the fourth frequency range.

[0182] For example, the terminal can also determine the VRB bundle in frequency domain range 1 and frequency domain range 2, which are available for DL ​​transmission and / or reception, respectively, in the i-th frequency domain range. A VRB bundle, numbered {0, 1, ...} -1}.

[0183] In some embodiments of this disclosure, the number and size of VRB bundles in the i-th frequency domain range can be determined according to the following formula: (Equation 7) in, Let i be the number of VRB bundles in the i-th frequency domain. Let i be the number of VRBs in the i-th frequency domain. Let L be the index of the starting VRB in the CRB within the i-th frequency domain range, L be the size of the VRB bundle, and mod represent the modulo operation. Then, the number of VRB bundles in the i-th frequency domain range can be determined. The size of the first VRB bundle can be calculated using the following formula: (Equation 8) in, This represents the size of the first VRB bundle within the i-th frequency domain. Then, the size of the last VRB bundle in the i-th frequency domain can be calculated using the following formula: (Equation 9) otherwise,

[0184] The sizes of other VRB bundles within the i-th frequency domain are .

[0185] Step 2305: Terminal 101 determines the number of PRBs and the frequency domain range.

[0186] In some embodiments, the number of PRBs can be the number of PRBs included in a PRB bundle. Optionally, the number of PRBs can be the number of PRBs included in each PRB bundle within the frequency domain range of the BWP.

[0187] In some embodiments, the frequency domain range may be the frequency domain range of the PRB bundle. Alternatively, the frequency domain range may be the frequency domain range of each PRB bundle within the frequency domain range of the BWP.

[0188] In some embodiments, terminal 101 may determine the number of PRBs included in each PRB bundle within the frequency domain range of the BWP and the frequency domain range of each PRB bundle.

[0189] In some embodiments, the terminal can determine the number of PRBs included in each PRB bundle within the frequency domain range of the BWP and the frequency domain range of each PRB bundle based on the bandwidth information of the BWP, the starting position of the BWP, and the fourth information.

[0190] Specifically, the division method for PRB bundling and VRB bundling is the same, which can be referred to in the relevant description of step 2303 above, and will not be repeated here.

[0191] Step 2306: Terminal 101 determines the second resource. In some embodiments, terminal 101 may determine a second resource in the SBFD time unit for downlink transmission and / or reception.

[0192] In some embodiments, the second resource is a PRB in the PRB bundle after interleaving mapping of VRB bundles that can be used for downlink transmission and / or reception in the first resource indicated by the second information determined by the terminal. The number of second VRBs and the second frequency domain range contained in the VRB bundles that can be used for downlink transmission and / or reception in the first resource indicated by the second information are determined by the terminal based on the first information, the number of first VRBs contained in each VRB bundle, and the first frequency domain range of each VRB bundle, in each frequency domain range that can be used for downlink transmission and / or reception in the BWP. The number of second VRBs is less than or equal to the number of first VRBs, and the second frequency domain range is the same as or a subset of the first frequency domain range.

[0193] In some embodiments, the SBFD time unit may simultaneously include a UL subband and a DL subband in the frequency domain. In some optional embodiments, the SBFD time unit may also include a guard band in the frequency domain. In some optional embodiments, when at least one SBFD symbol exists among the multiple symbols included in a time slot, the time slot may be referred to as an SBFD time slot.

[0194] In some embodiments, a “time unit” may be a “slot” or a “symbol”, which is not limited herein.

[0195] In some embodiments, the frequency domain resource allocation method is Type 1. The terminal determines the second resource in the sub-band full-duplex SBFD time unit for downlink transmission and / or reception by: based on the first information, the number of first VRBs included in each VRB bundle, and the first frequency domain range of each VRB bundle, within each frequency domain range available for downlink transmission and / or reception in the BWP, determining the number of second VRBs included in the VRB bundles available for downlink transmission and / or reception in the first resource indicated by the second information and the second frequency domain range; determining the PRB bundles after interleaving and mapping of the VRB bundles available for downlink transmission and / or reception in the first resource indicated by the second information, and using the PRBs in the PRB bundles as the second resource.

[0196] In some embodiments, the number of second VRBs is less than or equal to the number of first VRBs, and the second frequency domain range is the same as or a subset of the first frequency domain range.

[0197] In other words, the terminal can determine the number of VRBs in each VRB bundle that can be used for downlink transmission and / or reception, as well as the frequency domain range of each VRB bundle that can be used for downlink transmission and / or reception, based on the overlap between the frequency domain range that cannot be used for downlink transmission and / or reception indicated by the first information and the number of VRBs contained in each VRB bundle and the frequency domain range of each VRB bundle.

[0198] For example, such as Figure 2f and Figure 2g As shown, the network device allocates consecutive VRBs (i.e., first resources) to the UE via the RIV in the DCI, such as VRB#4-19. If the frequency domain range that cannot be used for downlink transmission and / or reception indicated in the first information is VRB#9-15, then the intersection VRB#9-15 cannot be used for downlink transmission and / or reception, and the remaining VRB#4-8 and VRB#16-19 can be used for downlink transmission and / or reception.

[0199] like Figure 2f As shown, the VRB bundles determined by the terminal within the frequency domain range of the BWP are VRB bundles #0-10, where the number of the first VRBs in the VRB bundles is: VRB bundles #0-9 include 2 VRBs, and VRB bundle #10 includes 1 VRB.

[0200] VRB bundles within the third frequency domain (i.e., the frequency domain where the first downlink subband overlaps with the BWP) and the fourth frequency domain (i.e., the frequency domain where the second downlink subband overlaps with the BWP) can be numbered starting from 0. For example, VRB bundles #0-3 within the third frequency domain can remain numbered #0-3, while VRB bundles within the fourth frequency domain can be updated from #7-10 to VRB bundles #0-3.

[0201] The system determines the first VRB bundle available for downlink transmission and / or reception in the first resource indicated by the second information, the number of second VRBs contained in each VRB bundle within the first VRB bundle, and the second frequency domain range. Within the third frequency domain range, the first VRB bundle includes VRB bundles #1-3, wherein the number of second VRBs in each VRB bundle is: VRB bundle #1-2 includes 2 VRBs (i.e., VRB#2-7), and VRB bundle #3 includes 1 VRB (i.e., VRB#8). Within the fourth frequency domain range, the first VRB bundle includes VRB bundles #0-1, wherein the number of second VRBs in each VRB bundle is: VRB bundle #0-1 includes 2 VRBs.

[0202] like Figure 2gAs shown, the terminal determines VRB bundling as VRB bundling #0-3 in the third frequency domain range, wherein the number of the first VRB in the VRB bundling is: VRB bundling #0-2 includes 2 VRBs, and VRB bundling #3 includes 1 VRB.

[0203] The terminal determines VRB bundling as VRB bundling #0-3 in the fourth frequency domain range, wherein the number of the first VRB in the VRB bundling is: VRB bundling #0-2 includes 2 VRBs, and VRB bundling #3 includes 1 VRB.

[0204] The system determines the first VRB bundle available for downlink transmission and / or reception in the first resource indicated by the second information, the number of second VRBs contained in each VRB bundle within the first VRB bundle, and the second frequency domain range. Within the third frequency domain range, the first VRB bundle includes VRB bundles #1-3, wherein the number of second VRBs in each VRB bundle is: VRB bundle #0-2 includes 2 VRBs, and VRB bundle #3 includes 1 VRB. Within the fourth frequency domain range, the first VRB bundle includes VRB bundle #0-1, wherein the number of second VRBs in each VRB bundle is: VRB bundle #0-1 includes 2 VRBs.

[0205] In some embodiments, determining which VRBs in the first resource indicated by the second information are available for downlink transmission and / or reception may be done by determining VRB bundles separately within the allocated DL frequency domain range, to ensure that the VRBs in the VRB bundles are available for DL ​​transmission and / or reception.

[0206] In some embodiments, the terminal performs interleaving mapping in multiple DL frequency domain ranges based on the fifth information sent by the network device, that is, maps VRB bundles to PRB bundles to ensure that the mapped PRB bundles are within the DL frequency domain range. In some embodiments, the terminal may map VRB bundles to PRB bundles in the following manner: 1) Bundle VRB with # -1 maps to PRB bundles# -1; where the index range of VRB bundling in the i-th frequency domain is 0~ -1, VRB bundled -1 refers to the last VRB bundle in the i-th frequency domain range.

[0207] 2) Other VRB bundles# Mapping to PRB bundles using row-to-row writing and column-to-column output. The specific mapping method is as follows:

[0208]

[0209]

[0210]

[0211]

[0212]

[0213] For example, such as Figure 2f As shown, the RIV in the DCI indicates the consecutive VRBs (i.e., the first resources) allocated to the UE, such as VRB#4-19. The frequency domain range that cannot be used for downlink transmission and / or reception indicated in the first information is VRB#9-15. Therefore, the intersection VRB#9-15 cannot be used for downlink transmission and / or reception, and the remaining VRB#4-8 and VRB#16-19 can be used for downlink transmission and / or reception.

[0214] The terminal can determine the number of first VRBs included in each VRB bundle within the frequency domain range of the BWP and the first frequency domain range of each VRB bundle based on the bandwidth information of the BWP, the starting position of the BWP, and the fourth information.

[0215] The VRB bundles determined by the terminal within the frequency domain range of the BWP are VRB bundles #0-10, where the number of the first VRBs in the VRB bundles is: VRB bundles #0-9 include 2 VRBs, and VRB bundle #10 includes 1 VRB.

[0216] VRB bundles within the third frequency domain (i.e., the frequency domain where the first downlink subband overlaps with the BWP) and the fourth frequency domain (i.e., the frequency domain where the second downlink subband overlaps with the BWP) can be numbered starting from 0. For example, VRB bundles #0-3 within the third frequency domain can remain numbered #0-3, while VRB bundles within the fourth frequency domain can be updated from #7-10 to VRB bundles #0-3.

[0217] The system determines the first VRB bundle available for downlink transmission and / or reception in the first resource indicated by the second information, the number of second VRBs contained in each VRB bundle of the first VRB bundle, and the second frequency domain range. Within the third frequency domain range, the first VRB bundle includes VRB bundles #1-3, wherein the number of second VRBs in each VRB bundle is: VRB bundles #1-2 each include 2 VRBs (i.e., VRB#4-5 and VRB#6-7), and VRB bundle #3 includes 1 VRB. Within the fourth frequency domain range, the first VRB bundle includes VRB bundles #0-1, wherein the number of second VRBs in each VRB bundle is: VRB bundles #0-1 each include 2 VRBs (i.e., VRB#16-17 and VRB#18-19).

[0218] Based on the first and second information, the mapping result for the third frequency domain range when the terminal performs interleaving mapping is determined as follows: VRB Bundle #0 mapped to PRB Bundle #0 VRB Bundle #1 Mapped to PRB Bundle #2 VRB Bundle #2 Mapped to PRB Bundle #1 VRB Bundle #3 Mapped to PRB Bundle #3 The mapping results for the fourth frequency domain range are as follows: VRB Bundle #0 mapped to PRB Bundle #0 VRB Bundle #1 Mapped to PRB Bundle #2 VRB Bundle #2 Mapped to PRB Bundle #1 VRB Bundle #3 Mapped to PRB Bundle #3 Based on the results of the first VRB bundling and mapping, the second resource is determined. The second resource includes: within the third frequency domain, PRB bundles #1-3, where each of PRB bundles #1-2 includes two PRBs (i.e., PRB #4-5 and PRB #6-7), and PRB bundle #3 includes one PRB (i.e., PRB #8). Within the fourth frequency domain, PRB bundle #0 and PRB bundles #0 and #2 each include two PRBs (i.e., PRB #16-17 and PRB #20-21). The final second resource includes PRB #4-7, PRB #16-17, and PRB #20-21.

[0219] For example, such as Figure 2g As shown, The RIV in the DCI indicates the consecutive VRBs (i.e., the first resources) allocated to the UE, such as VRB#4-19. If the frequency domain range that cannot be used for downlink transmission and / or reception indicated in the first information is VRB#9-15, then the intersection VRB#9-15 cannot be used for downlink transmission and / or reception, and the remaining VRB#4-8 and VRB#16-19 can be used for downlink transmission and / or reception.

[0220] The terminal can determine the number of first VRBs included in each VRB bundle and the first frequency range of each VRB bundle within the third and fourth frequency domain ranges, respectively, based on the bandwidth information of the BWP, the starting position of the BWP, the first information, and the fourth information. It can also determine the number of second VRBs included in each VRB bundle and the second frequency range of each VRB bundle within the third and fourth frequency domain ranges, respectively. At this point, the number of first VRBs in each VRB bundle equals the number of second VRBs, and the first frequency range of each VRB bundle equals the second frequency range.

[0221] The terminal determines VRB bundling as VRB bundling #0-3 in the third frequency domain range, wherein the number of the first VRB in the VRB bundling is: VRB bundling #0-2 includes 2 VRBs, and VRB bundling #3 includes 1 VRB.

[0222] The terminal determines VRB bundling as VRB bundling #0-3 in the fourth frequency domain range, wherein the number of the first VRB in the VRB bundling is: VRB bundling #0-2 includes 2 VRBs, and VRB bundling #3 includes 1 VRB.

[0223] The system determines the first VRB bundle available for downlink transmission and / or reception in the first resource indicated by the second information, the number of second VRBs contained in each VRB bundle of the first VRB bundle, and the second frequency domain range.

Figure 5 As shown, this disclosure relates to a resource determination method for a communication system, the method comprising: Step 5101: The network device sends the first information and the second information to the terminal.

Figure 2a Step 2101 Figure 2c Step 2201 Figure 2e Optional implementation methods of step 2301, and Figure 2a , Figure 2c , Figure 2e Other related parts in the embodiments involved.

[0387] Step 5102: Terminal 101 determines the second resource.

[0388] For optional implementations of step 5102, please refer to [link / reference]. Figure 2a Step 2102 Figure 2c Step 2202 Figure 2e Optional implementation methods for step 2302, and Figure 2a , Figure 2c , Figure 2e Other related parts in the embodiments involved. In some alternative embodiments, step 5101 may include Figure 3a Step 3102 and Figure 4a Step 4102, and Figures 3a-3e , Figures 4a-4c Optional implementation methods, and Figure 2a , Figure 2c , Figure 2eOther related parts in the embodiments involved will not be described in detail here.

[0389] In some embodiments, the above methods may include the methods described in the embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0390] The following is an exemplary description of the above method.

[0391] In some optional embodiments of this disclosure, the resource mapping method for PDSCH in a terminal under SBFD scenario includes at least one of the following: In some optional embodiments, the terminal can perform PDSCH resource mapping according to method 1 in the SBFD scenario: Method 1: The frequency domain resource allocation mode is type 0. The terminal receives the frequency domain range in the SBFD symbol that cannot be used for DL ​​transmission and / or reception in the RRC configuration or DCI indication. The RRC configuration includes parameters such as rbg-Size. The terminal receives the DCI, and the DCI indicates the scheduled RBG. Based on the DCI, the terminal determines the VRB in each RBG within the BWP that can be used for DL ​​transmission and / or reception, and determines the PRB that can be received for DL ​​transmission and / or reception.

[0392] For example, such as Figure 2b In the illustrated embodiment, the terminal determines that the frequency domain range that cannot be used for downlink transmission and / or reception includes the frequency domain range of the guard band and the uplink subband. It determines that the VRBs that overlap with the frequency domain ranges that can be used for DL ​​transmission and / or reception in the RBG are VRBs that can be used for DL ​​transmission and / or reception. The PRBs that can be used for DL ​​transmission and / or reception in the RBG allocated in the DCI are PRBs that can be used for DL ​​transmission and / or reception after non-interleaving mapping.

[0393] For example, if the terminal scheduling RBG includes RBG#1, #2, #3, #4, #5, #6, #7, and #8, then the four VRBs in RBG#1, #2, and #3 are all VRBs that can be used for DL ​​transmission and / or reception. The first VRB in RBG#4 is also a VRB that can be used for DL ​​transmission and / or reception. The last VRB in RBG#8 is also a VRB that can be used for DL ​​transmission and / or reception. The number of VRBs that can be used for DL ​​transmission and / or reception in RBG#5, #6, and #7 is 0. In some optional embodiments, the terminal can perform PDSCH resource mapping according to method 2 in the SBFD scenario: Method 2: The frequency domain resource allocation method is Type 1. The terminal configures or indicates the frequency domain range in the SBFD symbol that cannot be used for DL ​​transmission and / or reception based on RRC configuration or DCI; the terminal receives DCI, and the DCI indicates the scheduled VRB; the terminal determines the VRB in the BWP that can be used for DL ​​transmission and / or reception based on the received DCI, and determines the PRB to receive for DL ​​transmission and / or reception.

[0394] For example, the terminal determines that the overlapping frequency domain ranges of the VRBs that can be used for DL ​​transmission and / or reception are the VRBs that can be used for DL ​​transmission and / or reception, and the PRBs that can be used for DL ​​transmission and / or reception among the VRBs allocated in the DCI are the PRBs that can be used for DL ​​transmission and / or reception after non-interleaving mapping.

[0395] In some optional embodiments, the terminal can perform PDSCH resource mapping according to method 3 in the SBFD scenario: Method 3: The frequency domain resource allocation method is Type 1. The terminal indicates the frequency domain range in the SBFD symbols that cannot be used for DL ​​transmission and / or reception based on the RRC configuration or DCI. The RRC configuration may include interleaving parameters such as vrb-ToPRB-Interleaver. The terminal receives the DCI, which indicates the scheduled VRBs. Based on the received DCI, the terminal determines the VRBs that can be used for DL ​​transmission and / or reception in each VRB bundle within the BWP, and determines the PRBs that can be received for DL ​​transmission and / or reception.

[0396] For example: Figure 2g In the illustrated embodiment, the terminal determines VRB bundling in frequency domain range 1 and frequency domain range 2, which are available for DL ​​transmission and / or reception, respectively; the terminal determines PRB bundling in frequency domain range 1 and frequency domain range 2, which are available for DL ​​transmission and / or reception, respectively, in the same way as the VRB bundling method; the VRB indicated by DCI and the VRB overlapping in frequency domain range 1 and frequency domain range 2 are the actually allocated VRBs, and the terminal performs VRB bundling to PRB bundling mapping in frequency domain range 1 and frequency domain range 2 based on the actually allocated VRBs.

[0397] For example, the terminal assigns VRB bundles 1, 2, and 3 in frequency domain range 1, and interleaves PRB bundles 1, 2, and 3 mapped to frequency domain range 1 within frequency domain range 1; and assigns VRB bundles 0 and 1 in frequency domain range 2, and interleaves PRB bundles 0 and 2 mapped to frequency domain range 2 within frequency domain range 2.

[0398] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0399] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC), and the functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD), such as a field-programmable gate array (FPGA), which can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0400] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
