Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a signal processing method, communication node, medium, and program product. Background Technology

[0002] In wireless communication systems, the network plans and dynamically schedules network resources based on the actual needs of user equipment (UE) and the Quality of Service (QoS) requirements of different service flows, using Virtual Resource Blocks (VRBs) as the basic unit. Since the network actually transmits data in the active Bandwith Path (BWP) portion using Physical Resource Blocks (PRBs) as the basic unit, the base station and UE also need to complete the step of mapping data from VRB resources to PRB resources according to resource indication information. This process then converts the signal to the time domain and transmits it on the Physical Downlink Shared Channel (PDSCH) and Physical Uplink Shared Channel (PUSCH).

[0003] In traditional wireless communication systems, PDSCH and PUSCH resource scheduling employs multiple resource allocation types: Type 0, based on Resource Block Groups (RBGs), and Type 1, based on a starting Resource Block (RB) and a continuous RB segment, to adapt to different application scenarios and improve resource scheduling flexibility. For each resource allocation type, different DCI frequency domain resource indication methods are used to reduce resource indication overhead. Furthermore, RB bundling and VRB to PRB interleaving patterns are introduced to improve resource allocation efficiency and obtain frequency diversity gain, respectively. For UE transmission bandwidth, the base station configures a BWP for the UE via RRC signaling or DCI, including the first active BWP allocated when the UE accesses the network (initial BWP) and other active BWPs configured for the UE in subsequent communications. For resource allocation type 1, the UE is allocated a continuous RB within the BWP, which supports VRB to PRB interleaving. Since the VRB to PRB interleaving pattern is applied to the RB packets within the entire BWP resource, if the active BWP and initial BWP are nested, the resource location of the active BWP allocated to the UE may partially overlap with the resource location of the initial BWP, reducing transmission reliability. Summary of the Invention

[0004] This application provides a signal processing method, communication node, medium, and program product. For cases where there may be nested active BWPs and initial BWPs within the BWPs allocated to the UE, it implements configuration and mapping rule determination for the two types of frequency domain resources, avoiding the increase in data bit rate due to BWP occupation and improving transmission reliability.

[0005] To achieve the above objectives, embodiments of this application provide a signal processing method, including:

[0006] Receive Type I control signaling and Type II control signaling;

[0008] In response to the first condition, based on the first frequency domain resource, the second frequency domain resource, a subset of the second frequency domain resource, and the third resource unit set, a mapping pattern based on the interleaving mode is determined for the second frequency domain resource of the first type and the second frequency domain resource of the second type; wherein, the first type is the type of virtual frequency domain resource, and the second type is the type of physical frequency domain resource;

[0009] Based on the mapping pattern, a subset of the second frequency domain resources of the first type is mapped to a subset of the second frequency domain resources of the second type.

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0032] The steps illustrated in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in a different order than that presented here.

[0033] The signal processing method provided in this application can be applied to wireless communication systems. When a UE accesses the network, the BWP allocated to it may include an initial BWP and an active BWP. In cases where the two are nested, which will affect the VRB to PRB interleaving, a new frequency domain resource allocation scheme is proposed. This scheme includes configuration methods for both VRB and PRB resource types, as well as mapping rules between VRB and PRB, to avoid the increase in data transmission rate caused by the initial BWP occupying resources and improve signal transmission reliability.

[0034] In wireless communication systems, the network plans and dynamically schedules network resources based on VRBs (Virtual Realm Blocks) according to the actual needs of UEs and the QoS requirements of different service flows. VRB configuration information can be carried by Radio Resource Control (RRC) signaling, Downlink Control Information (DCI), System Information Blocks (SIBs), and UE-reported information. Since the network actually transmits data in activated BWPs using PRBs as the basic unit, the base station and UE also need to map data from VRB resources to PRB resources based on resource indication information (i.e., the number and index of VRBs), and then convert the signal to the time domain for transmission on PDSCH and PUSCH.

[0035] In traditional wireless communication systems, PDSCH and PUSCH resource scheduling employs multiple resource allocation types, including RGB-based frequency domain RA type 0 and frequency domain RA type 1 based on a continuous segment of RBs starting from the first RB, to adapt to different application scenarios (e.g., high-throughput scenarios and low-bandwidth or low-latency scenarios) and improve resource scheduling flexibility. For each resource allocation type, different DCI frequency domain resource indication methods are used (indicating VRB resources, which are then mapped from the VRB to the PRB and transmitted via Orthogonal Frequency Division Multiplexing (OFDM) modulation) to reduce resource indication overhead.

[0036] In addition, RB bundling type and VRB to PRB interleaving pattern function are introduced to improve resource allocation efficiency and obtain frequency diversity gain, respectively. For UE transmission bandwidth, the base station configures a BWP for the UE via RRC signaling or DCI, including the first active BWP assigned when the UE accesses the network (initial BWP), and other BWPs configured for the UE in subsequent communications (active BWPs). The initial BWP is used for operations such as random access and typically has a smaller bandwidth; the active BWP is used for data transmission and typically has a larger bandwidth. Figure 1 An example diagram illustrating the frequency domain resource location relationship between initial BWP and active BWP in existing technologies, such as... Figure 1 As shown on the left, the two are nested, meaning the initial BWP is located within the bandwidth range of the active BWP or overlaps with the bandwidth range of the active BWP; for example... Figure 1 As shown on the right, the two are managed independently, meaning that the initial BWP and the active BWP do not overlap.

[0037] For RA type 0, frequency domain resources are allocated in units of RGB. DCI indicates the allocation of each RGB in the form of a bitmap. It supports discrete RGB configurations, does not support VRB to PRB interleaving, and is not affected by the positional relationship of frequency domain resources between the initial BWP and the active BWP.

[0038] For RA type 1, the UE is allocated a continuous RB within the BWP, supporting VRB to PRB interleaving. Since the VRB to PRB interleaving pattern is applied to the RB bundle within the entire BWP resource, if the active BWP and initial BWP are nested, the resource location of the active BWP allocated to the UE may partially overlap with the resource location of the initial BWP, leading to reduced transmission reliability.

[0039] For RA type 1, assuming there are N RB bundles within a 100MHz active BWP, and the RB bundling size is 2, meaning each RB bundle includes 2 RBs. The interleaving unit of the VRB to PRB interleaving pattern is R = 2. The mapping relationship between VRB bundle j and PRB bundle f(j) in the VRB to PRB interleaving mode is as follows:

[0040] f(j) = rC + c

[0041] j = cR + r

[0042] r = 0, 1, ..., R-1

[0043] c = 0, 1, ..., C-1

[0044] R=2

[0045]

[0046] That is, N RB bundles are interleaved by a VRB (with units of 2) to a PRB (R×C dimensional interleaver). After that, the VRB bundle indexes in the order {0,2,4,...,N-2,1,3,5,...,N-1} are mapped sequentially to the PRB bundle indices 0 to N-1 corresponding to the active BWP frequency domain resources. Figure 2 A schematic diagram illustrating the mapping relationship from VRB to PRB for RA type 1 provided in this application embodiment is shown below. Figure 2As shown, if the DCI instructs the UE to be allocated 20 VRBs, the PRB bundle index used during data transmission is {0,N / 2,1,N / 2+1,2,N / 2+2,3,N / 2+3,4,N / 2+4}, causing the PRB located in the initial BWP to be unavailable, affecting the effectiveness and reliability of the transmission.

[0047] Meanwhile, the existing higher-layer parameter RateMatchPattern can configure unavailable RB resources in the active BWP where the UE's scheduling PDSCH is located. However, the aforementioned unavailable RB resources are used to determine the transport block size carried by the PDSCH. In the VRB toPRB interleaving pattern, the data still needs to be mapped to the PRB resource corresponding to the initial BWP, and the corresponding data will be punctured. This leads to an increase in the data transmission rate (which may exceed 0.93), and the data will not be able to be decoded or will be decoded successfully.

[0048] Based on the above description, in wireless communication systems, for RA type 1 with continuous indication, and for existing higher-level parameter frequency domain resource configuration methods where unavailable RB resources can be configured but data mapping rules cannot be changed, nested initial BWPs and active BWPs will affect data transmission reliability. To solve the above problems, this application provides a signal processing method that, for cases where nested active BWPs and initial BWPs may exist within the BWPs allocated to the UE, implements the configuration and mapping rule determination for two types of frequency domain resources, VRB and PRB, avoiding the increase in data code rate due to BWP occupation and improving transmission reliability. The signal processing method provided in this application can be implemented in a communication node, which can be a transmitting communication device applied in current wireless communication systems, as well as in next-generation 6G communication systems and subsequent communication systems (6G and beyond), such as base station, terminal, relay station, or satellite communication devices, or transmitting communication devices in next-generation fixed access wireless communication systems, such as access points (ACs) or terminals. This application does not limit this. In some possible implementations, signal processing methods can be implemented by calling computer-readable instructions stored in memory.

[0049] In one exemplary implementation Figure 3 The flowchart illustrates a signal processing method provided in this application embodiment. This method can be applied to a wireless communication system and is used to configure resources and mapping rules for active BWPs and initial BWPs that have a nested relationship. This method can be executed by a signal processing device, which can be implemented by software and / or hardware and integrated on the communication node.

[0050] like Figure 3 As shown, the signal processing method provided in this application embodiment specifically includes the following steps:

[0051] S101, Receive Type I control signaling and Type II control signaling.

[0052] In this embodiment, the first type of control signaling can be specifically understood as signaling used to indicate the resource information required for the current signal transmission. The second type of control signaling can be specifically understood as higher-layer signaling used to configure the resource information available for signal transmission as a whole.

[0053] In a specific example, before signal processing and transmission, the reception of Type I and Type II control signaling related to resource configuration will be performed first.

[0054] S102. Determine the first frequency domain resources and a subset of the second frequency domain resources based on the configuration information of the second type of control signaling and the indication information of the first type of control signaling.

[0055] The second frequency domain resources include the third resource unit set.

[0056] In this embodiment, the first frequency domain resource can be specifically understood as the frequency domain resource corresponding to the initial BWP in the above example. The second frequency domain resource can be specifically understood as the frequency domain resource corresponding to the active BWP in the above example. The subset of the second frequency domain resource can be specifically understood as the frequency domain resource selected by the first type of control signaling and required to be used in the current signal processing transmission from the second frequency domain resources configured by the second round of control signaling. The third resource unit set can be specifically understood as the set of resource units in the second frequency domain resource that do not correspond to or overlap with the first frequency domain resource.

[0057] In a specific example, the first and second frequency domain resources required for signal transmission are configured as a whole according to the configuration information of the second type of control signaling, and a subset of the second frequency domain resources required for the current signal processing transmission is selected from the second frequency domain resources according to the indication information of the first type of control signaling.

[0058] In some examples, the first frequency domain resource includes at least one of the following:

[0059] A carrier unit with a first specific number; a common set of carrier units; a common set of RB resources; a common set of resource element (RE) resources; a BWP with a first specific variation; frequency domain resources configured by a first message or signaling; and frequency domain resources for transmitting a first specific signal.

[0060] In some examples, the frequency domain resources configured by the first message or signaling include at least one of the following:

[0061] Frequency domain resources configured by common messages or signaling; BWP configured by the Main Information Block (MIB); BWP configured by the System Information Block (SIB); BWP#0 configured by the higher-level parameters BWP-DownlinkCommon and BWP-UplinkCommon in the ServingCellConfigCommon IE; BWP#0 configured by the higher-level parameters BWP-DownlinkDedicated or BWP-UplinkDedicated in the ServingCellConfig IE; BWP#0 indicated by DCI; RedCap-specific initial DL / UL BWP; Control Resource Set (CORESET) 0.

[0062] In some examples, the first specific number can be 0.

[0063] In some examples, the frequency domain resources used to transmit the first specific signal include the CORESET where the DCI of the PDSCH monitored in any Common Search Space (CSS) is located.

[0064] In some examples, the first frequency domain resources are used for the transmission of the first common signal.

[0065] In some examples, the first common signal includes at least one of the following:

[0066] The Synchronization Signal / Physical Broadcast Channel Block (SSB); PDCCH carrying DCI format 1-0; SIB1; Message (Msg)B; Msg2; Msg4; Short Message; Cyclic Redundancy Check (CRC); and at least one of the DCI-scheduled PDSCHs scrambled with the First Radio Network Temporary Identifier (RNTI).

[0067] In some examples, the first specific RNTI includes System Information-Radio Network Temporary Identifier (SI-RNTI), Paging-Radio Network Temporary Identifier (P-RNTI), Cell-Radio Network Temporary Identifier (C-RNTI), Configured Scheduling-Radio Network Temporary Identifier (CS-RNTI), Modulation and Coding Scheme-Cell Radio Network Temporary Identifier (MCS-C-RNTI), Random Access-Radio Network Temporary Identifier (RA-RNTI), Message B-Radio Network Temporary Identifier (MsgB-RNTI), and Temporary Cell-RNTI (TC-RNTI).

[0068] In some examples, the second frequency domain resource includes at least one of the following:

[0069] A carrier element with a second specific number; a set of subcarrier elements specific to the UE; a set of RB resources specific to the UE; a set of RE resources specific to the UE; a BWP with a second specific number; and frequency domain resources configured by a second message or signaling.

[0070] In some examples, the frequency domain resources configured by the second message or signaling include at least one of the following:

[0071] Frequency domain resources configured by UE-specific messages or signaling; BWPs configured by the higher-level parameters BWP-Downlink or BWP-Uplink in the ServingCellConfig IE; BWPs indicated by the 'Bandwidth part indicator' field of the DCI.

[0072] In some examples, the second specific number can be an integer greater than 0.

[0073] In some examples, the second frequency domain resources are used for the transmission of second UE-specific signals or channels.

[0074] In some examples, the second UE-specific signal or channel includes at least one of the following: DCI 1-0 / 1-1 / 1-2 / 1-3 / 4-0 / 4-1 / 4-2 scheduled PDSCH, DCI format 1-1 activated semi-persistent scheduling (SPS) PDSCH, and PDCCH.

[0075] S103. In response to the first condition, determine the interleaving-based mapping pattern of the second frequency domain resources of the first type and the second frequency domain resources of the second type based on the first frequency domain resources, the second frequency domain resources, the subset of the second frequency domain resources and the third resource unit set.

[0076] The first type is the type of virtual frequency domain resources, and the second type is the type of physical frequency domain resources.

[0077] In this embodiment, the first type can be specifically understood as the resource type corresponding to VRB, and the second type can be specifically understood as the resource type corresponding to PRB.

[0078] In this embodiment, the first condition can be specifically understood as a condition used to determine whether the current signal processing can perform an interleaving-based mapping.

[0079] In this embodiment, a one-to-one mapping relationship is satisfied between the first frequency domain resources of the first type and the first frequency domain resources of the second type; a mapping relationship of specific patterns is satisfied between the second frequency domain resources of the first type and the second frequency domain resources of the second type; wherein, the specific patterns include interleaving patterns based on resource unit groups and / or interleaving patterns based on resource units.

[0080] In a specific example, if the first condition is met, it can be determined that the signal transmission to be performed now requires a mapping based on the interleaving mode. This mapping is a mapping between the second frequency domain resources of the first type and the second frequency domain resources of the second type, that is, a mapping from the second frequency domain resources of the VRB to the second frequency domain resources of the PRB. At this time, the mapping pattern based on the interleaving mode between the second frequency domain resources of the first type and the second frequency domain resources of the second type can be determined based on the first frequency domain resources, the second frequency domain resources, the subset of the second frequency domain resources and part or all of the third resource unit set.

[0081] S104. Based on the mapping pattern, complete the mapping of a subset of the second frequency domain resources of the first type to a subset of the second frequency domain resources of the second type.

[0082] In a specific example, after clarifying the mapping pattern between the second frequency domain resources of the first type and the second frequency domain resources of the second type, the mapping between the subset of the second frequency domain resources of the first type and the subset of the second frequency domain resources of the second type can be completed based on the mapping pattern and using the subset of the second frequency domain resources required for the current signal processing.

[0083] The signal processing method provided in this application embodiment receives a first type of control signaling and a second type of control signaling; determines a first frequency domain resource and a subset of the second frequency domain resource based on the configuration information of the second type of control signaling and the indication information of the first type of control signaling; wherein the second frequency domain resource includes a third resource unit set; in response to a first condition, determines a mapping pattern based on an interleaving mode for second frequency domain resources of a first type and second type based on the first frequency domain resource, the second frequency domain resource, the subset of the second frequency domain resource, and the third resource unit set; wherein the first type is a type of virtual frequency domain resource, and the second type is a type of physical frequency domain resource; and completes the mapping from a subset of second frequency domain resources of the first type to a subset of second frequency domain resources of the second type based on the mapping pattern. By adopting the above technical solution, for the case where there may be nested active BWPs and initial BWPs within the BWP allocated to the UE, the configuration and mapping rules for frequency domain resources of two types, VRB and PRB, are determined, avoiding the increase in data bit rate due to BWP occupation and improving transmission reliability.

[0084] In one embodiment, the third resource unit set includes a first type of third resource unit set and a second type of third resource unit set.

[0085] Wherein, the third resource unit set of the first type is configured as one or more resource units in the second frequency domain resource of the first type, and when there is a mapping relationship with the first frequency domain resource of the second type, one or more resource units in the second frequency domain resource of the first type;

[0086] Wherein, the third resource unit set of the second type is configured as one or more resource units in the first frequency domain resource of the second type, and when it overlaps with one or more resource units in the second frequency domain resource of the second type, one or more resource units in the second frequency domain resource of the second type.

[0087] In a specific example, the third resource unit set of the first type can be understood as the set of one or more resource units in the second frequency domain resources of the first type that have a mapping relationship with one or more resource units in the second frequency domain resources of the first type, when there is a mapping relationship between one or more resource units in the second frequency domain resources of the first type and one or more resource units in the second frequency domain resources of the second type.

[0088] In a specific example, the third resource unit set of the second type can be understood as the set of one or more resource units in the first frequency domain resource of the second type that overlap with one or more resource units in the second frequency domain resource of the second type. That is, when there is an overlap between the resource unit corresponding to the initial BWP and the resource unit corresponding to the active BWP in the PRB, the overlapping one or more resource units constitute the set.

[0089] In one embodiment, determining an interleaving-mode-based mapping pattern of second frequency domain resources of a first type and second frequency domain resources of a second type, based on a first frequency domain resource, a second frequency domain resource, and a third resource unit set, includes:

[0126] In some examples, the control resource set of the first type of control signaling is the first type of control resource set: wherein, when the first type of control signaling is DCI format 1-0, the first type of CORESET is the control resource set other than CORESET0.

[0127] In some examples, the first type of control signaling includes a specific indication field or indication information: wherein the first type of control signaling is used to indicate the activation of SPS; for example, the first type of control signaling is DCI format 1-0 / 1-1 / 1-2 / 1-3 / 4-0 / 4-1 / 4-2, including at least one of rate match indication information, PRB bundle indication information, VRB to PRB mapping indication information, BWP indication information, and frequency domain resource allocation indication information.

[0130] In some examples, the first frequency domain resource of the second type and the second frequency domain resource of the second type have overlapping resource units in the frequency domain: wherein, the index of the starting resource unit of the first frequency domain resource of the first type is not less than the index of the starting resource unit of the second frequency domain resource of the first type, and the index of the starting resource unit of the first frequency domain resource of the second type is not less than the index of the starting resource unit of the second frequency domain resource of the second type; the number of resource units of the first frequency domain resource of the first type is not greater than the number of resource units of the second frequency domain resource of the first type, and the number of resource units of the first frequency domain resource of the second type is not greater than the number of resource units of the second frequency domain resource of the second type; the index of the ending resource unit of the first frequency domain resource of the first type is not greater than the index of the ending resource unit of the second frequency domain resource of the first type, and the index of the ending resource unit of the first frequency domain resource of the second type is not greater than the index of the ending resource unit of the second frequency domain resource of the second type.

[0131] In some examples, a subset of the second frequency domain resources of the first type includes at least one resource element mapped to an overlapping resource element: wherein, higher-layer parameters indicate that the frequency domain resources of the first type and the frequency domain resources of the second type are mapped based on an interleaving mode, the UE determines the mapping relationship between the VRB resources and PRB resources indicated by the DCI according to the interleaving pattern, and at least one RB in the VRB resources is mapped to the PRB that overlaps with the second frequency domain resources and the first frequency domain resources.

[0132] In some examples, the user terminal supports a specific protocol version: the UE supports a release version no lower than Release 19, or the UE supports the 6G protocol version.

[0133] In one embodiment, based on a first frequency domain resource, a second frequency domain resource, a subset of the second frequency domain resource, and a third resource unit set, a mapping pattern of the second frequency domain resources of the first type and the second frequency domain resources of the second type is determined, including at least one of the following:

[0134] Resource units of a subset of second frequency domain resources of the first type are grouped and numbered. In response to a first condition, resource units of second frequency domain resources of the first type and second frequency domain resources of the second type, excluding first frequency domain resources of the first type and first frequency domain resources of the second type, are grouped and numbered to generate a first specific pattern for interleaving-mode mapping between second frequency domain resources of the first type and second frequency domain resources of the second type.

[0135] Resource units of the second frequency domain resources of the first type or the second type are grouped and numbered to generate a second specific pattern for mapping between the second frequency domain resources of the first type and the second frequency domain resources of the second type based on an interleaving mode. In response to a first condition, when a subset of the second frequency domain resources of the first type is mapped to the second frequency domain resources of the second type, resource units belonging to the first frequency domain resources of the second type are skipped, and mapped to the resource units / resource unit groups of the second type of the second frequency domain resources that have a mapping relationship with the resource units / resource unit groups of the next closest second frequency domain resources of the first type; wherein, the resource units / resource unit groups of the next closest second frequency domain resources of the first type do not include resource units of the first frequency domain resources of the second type or are not all of the first frequency domain resources of the second type; wherein, the resource units / resource unit groups of the next closest second frequency domain resources of the first type represent the resource units of the second frequency domain resources of the first type that are closest to and greater than the index / number of the resource units of the second frequency domain resources of the first type to be mapped.

[0136] In response to a first condition, resource units other than those in the first frequency domain resources of the first type / second frequency domain resources of the second type are grouped and numbered to generate a third specific pattern for mapping between the second frequency domain resources of the first type and the second frequency domain resources of the second type based on an interleaving mode; wherein the number of resource units in the subset of the second frequency domain resources of the first type is no greater than the number of resource units in the second frequency domain resources of the second type excluding the number of resource units in the first frequency domain resources of the second type.

[0137] The resource unit groups of the second frequency domain resources of the first type are mapped to the resource unit groups of the second frequency domain resources of the second type according to the fourth specific pattern, and the resource unit groups of the second frequency domain resources of the first type and the resource units within the resource unit groups of the second frequency domain resources of the second type that satisfy the mapping relationship of the fourth specific pattern are mapped to the resource units according to the fifth specific pattern.

[0138] In some examples, in response to a first condition, based on a first frequency domain resource, a second frequency domain resource, a subset of the second frequency domain resource, and a third resource unit set, a mapping pattern based on an interleaving mode is determined between second frequency domain resources of the first type and second frequency domain resources of the second type. The mapping pattern is then used to complete the mapping from a subset of the first type of second frequency domain resources to a subset of the second type of second frequency domain resources. This is specifically achieved as follows:

[0139] The resource elements of a subset of second frequency domain resources of the first type are grouped and numbered; in response to a first condition, the UE skips / ignores first frequency domain resources of the first type within second frequency domain resources of the first type, or first frequency domain resources of the second type within second frequency domain resources of the second type; the resource elements of second frequency domain resources of the first type / second frequency domain resources of the second type, excluding first frequency domain resources of the first type / second frequency domain resources of the second type, are grouped and numbered; a first specific pattern is generated for mapping between second frequency domain resources of the first type and second frequency domain resources of the second type based on an interleaving mode; and the mapping between subsets of second frequency domain resources of the first type and subsets of second frequency domain resources of the second type is completed based on the first specific pattern.

[0140] In some examples, in response to a first condition, based on a first frequency domain resource, a second frequency domain resource, a subset of the second frequency domain resource, and a third resource unit set, a mapping pattern based on an interleaving mode is determined between second frequency domain resources of the first type and second frequency domain resources of the second type. The mapping pattern is then used to complete the mapping from a subset of the first type of second frequency domain resources to a subset of the second type of second frequency domain resources. This is specifically achieved as follows:

[0141] Resource units of the second frequency domain resources of the first type, or resource units of the second frequency domain resources of the second type, are grouped and numbered to generate a second specific pattern for mapping between the subset of the second frequency domain resources of the first type and the second frequency domain resources of the second type based on an interleaving mode. In response to a first condition, when mapping a subset of the second frequency domain resources of the first type to the second frequency domain resources of the second type, resource units belonging to the first frequency domain resources of the second type are skipped, and the mapping is performed on resource units / resource unit groups of the second frequency domain resources of the second type that have a mapping relationship with the nearest next first-type second frequency domain resource resource / resource unit group; wherein, the nearest next first-type second frequency domain resource resource unit / resource unit group does not include resource units of the first frequency domain resources of the second type or does not entirely belong to the first frequency domain resources of the second type; wherein, the nearest next first-type second frequency domain resource resource unit / resource unit group represents the resource unit of the second frequency domain resources of the first type that is closest to and greater than the index / number of the resource unit of the second frequency domain resources of the first type to be mapped.

[0142] In some examples, in response to a first condition, based on a first frequency domain resource, a second frequency domain resource, a subset of the second frequency domain resource, and a third resource unit set, a mapping pattern based on an interleaving mode is determined between second frequency domain resources of the first type and second frequency domain resources of the second type. The mapping pattern is then used to complete the mapping from a subset of the first type of second frequency domain resources to a subset of the second type of second frequency domain resources. This is specifically achieved as follows:

[0143] In response to the first condition, resource units corresponding to the first frequency domain resources of the first type in the second frequency domain resources of the first type, or resource units corresponding to the first frequency domain resources of the second type in the second frequency domain resources of the second type, are first excluded. The remaining resource units are then grouped and numbered to generate a third specific pattern for mapping between second frequency domain resources of the first type and second frequency domain resources of the second type based on an interleaving mode. At this point, the numbers in the third specific pattern are consecutive. Based on the third specific pattern, a mapping is completed from a subset of second frequency domain resources of the first type to a subset of second frequency domain resources of the second type. The number of resource units in the subset of second frequency domain resources of the first type is no greater than the number of resource units in the second frequency domain resources of the second type excluding the number of resource units in the first frequency domain resources of the second type.

[0144] In some examples, in response to a first condition, based on a first frequency domain resource, a second frequency domain resource, a subset of the second frequency domain resource, and a third resource unit set, a mapping pattern based on an interleaving mode is determined between second frequency domain resources of the first type and second frequency domain resources of the second type. The mapping pattern is then used to complete the mapping from a subset of the first type of second frequency domain resources to a subset of the second type of second frequency domain resources. This is specifically achieved as follows:

[0145] In response to the first condition, a fourth specific pattern is constructed between the resource unit groups of the first type of second frequency domain resources and the resource unit groups of the second type of second frequency domain resources. This fourth specific pattern is used for interleaving-based mapping between resource unit groups. A fifth specific pattern is also constructed between the resource units within the resource unit groups of the first type of second frequency domain resources and the resource units within the resource unit groups of the second type of second frequency domain resources. This fifth specific pattern is used for interleaving-based mapping between resource units within the resource unit groups. Then, based on the constructed fourth and fifth specific patterns, the mapping from a subset of the first type of second frequency domain resources to a subset of the second type of second frequency domain resources is completed.

[0146] It should be clarified that the fourth and fifth specific patterns can be used simultaneously, or one can be chosen to be used depending on the actual situation. When both are used simultaneously, the resource unit groups in the subset of the second frequency domain resources of the first type and the resource unit groups in the subset of the second frequency domain resources of the second type will first be mapped according to the fourth specific pattern. Then, the resource unit groups of the second frequency domain resources of the first type and the resource unit groups of the second frequency domain resources of the second type that satisfy the mapping relationship of the fourth specific pattern will be mapped according to the fifth specific pattern.

[0147] In one embodiment, the third resource unit set of the first type or the third resource unit set of the second type includes X resource units / groups of resource units, and the second frequency domain resource of the first type or the second frequency domain resource of the second type includes a maximum of N resource units / groups of resource units. Accordingly, in response to a first condition, based on the first frequency domain resource, the second frequency domain resource, a subset of the second frequency domain resource, and the third resource unit set, a mapping pattern based on the interleaving mode of the second frequency domain resource of the first type and the second frequency domain resource of the second type is determined, including:

[0149] Based on the NX available resource units / groups of available resource units of the first type and the NX available resource units / groups of available resource units of the second type, a mapping pattern based on the interleaving mode is generated between the second frequency domain resources of the first type and the second frequency domain resources of the second type.

[0150] The mapping pattern is used for mapping between NX available resource units / groups of available resource units of the first type and NX available resource units / groups of available resource units of the second type.

[0151] In this embodiment, the available resource unit / group of available resource units can be specifically understood as the resource unit / group of resource units in the second frequency domain resources of the first type or the second type that can be used for interleaving mapping.

[0152] In one embodiment, determining the NX available resource units / groups included in the second frequency domain resources of the second type, and / or the NX available resource units / groups included in the second frequency domain resources of the first type, based on X resource units / groups and a maximum of N resource units / groups, includes:

[0157] or

[0158] The starting position index or minimum index value of the NX available resource units / groups of available resource units included in the second frequency domain resources of the second type, and / or the NX available resource units / groups of available resource units included in the second frequency domain resources of the first type, is determined to be 0;

[0159] Wherein, the indices of the NX available resource units / groups of available resource units included in the second frequency domain resources of the second type and / or the NX available resource units / groups of available resource units included in the second frequency domain resources of the first type are consecutive.

Accordingly, in response to a first condition, based on the first frequency domain resource, the second frequency domain resource, a subset of the second frequency domain resource, and the third resource unit set, a mapping pattern based on the interleaving mode of the second frequency domain resource of the first type and the second frequency domain resource of the second type is determined, including:

[0161] A mapping pattern based on an interleaving mode is generated between the second frequency domain resources of the first type and the second frequency domain resources of the second type, based on the maximum N resource units / resource unit groups of the first type and the maximum N resource units / resource unit groups of the second type.

[0162] The mapping pattern is used for mapping between N resource units / groups of resource units of the first type and N resource units / groups of resource units of the second type.

[0163] Accordingly, when a resource unit / group of resource units in a subset of second-frequency-domain resources of the first type has a mapping relationship with a resource unit / group of resource units in a third-frequency-domain resource set of the second type, the mapping from a subset of second-frequency-domain resources of the first type to a subset of second-frequency-domain resources of the second type is completed based on the mapping pattern, including:

[0169] In one embodiment, the available resource units / available resource unit indices of the second frequency domain resources of the first type are non-contiguous, and / or the available resource units / available resource unit indices of the second frequency domain resources of the second type are contiguous;

[0170] The available resource units of the second frequency domain resources of the first type and the available resource units of the second frequency domain resources of the second type are determined based on X resource units / resource unit groups and a maximum of N resource units / resource unit groups.

[0171] It is understood that the available resource units of the second frequency domain resources of the first type and the available resource units of the second frequency domain resources of the second type are determined in the same way as the above-mentioned available resource units, and no further restrictions are imposed here.

[0172] In one embodiment, the fourth resource unit or group of fourth resource units of the second type is a resource unit / group of resource units in the second frequency domain resource of the second type;

Furthermore, the UE can generate an interleaving-based mapping pattern according to the NX available resource units / available resource unit groups in the second frequency domain resources of the first type or the second type, and use the generated interleaving-based mapping pattern for mapping between the resource units / resource unit groups of the NX first-type second frequency domain resources and the resource units / resource unit groups of the second-type second frequency domain resources.

[0231] In some examples, the second frequency domain resources of the second type include NX available resource units / groups of available resource units, and / or a subset of the second frequency domain resources of the first type include a maximum of NX available resource units / groups of available resource units, which can be determined based on the position of resource units in the third resource unit set of the first type within the second frequency domain resources, or based on the position of resource units in the third resource unit set of the second type within the second frequency domain resources. Furthermore, the indices of the NX available resource units / groups of available resource units included in the second frequency domain resources of the second type, and / or the NX available resource units / groups of available resource units included in the second frequency domain resources of the first type, are either consecutive or non-consecutive.

[0271] in,

[0272] Existing technologies utilize all Resource Blocks (RBs) within the entire active Base Window (BWP) to generate an interleaving-based mapping pattern. All PDSCH transmissions within this active BWP must perform information mapping to PRBs according to this interleaving-based mapping pattern. When a significant portion of the RBs within the active BWP are unavailable for PDSCH transmission, if the Data Interchange Controller (DCI) indicates a continuous segment of RBs for PDSCH transmission, the indicated continuous RBs in the interleaving-based mapping pattern will have a mapping relationship with a discrete segment of PRBs in the mapping pattern. This can easily lead to the indicated RBs being mapped to RBs unavailable for PDSCH transmission. Therefore, this invention proposes a scheme to narrow the range of RBs used to generate the interleaving-based mapping pattern, supporting the use of interleaving-based mapping only within the scheduled RBs, thus avoiding frequent impacts on the actual transmission rate of PDSCH from RBs unavailable for PDSCH transmission. Using the following scheme of this invention can significantly reduce the probability of resource collisions, improve scheduling flexibility, and ensure reliable data transmission.

[0273] Solution 3: A solution is proposed that defines RB bundles based on active BWP resources. During the VRB to PRB mapping process, the RB resources corresponding to the initial BWP are skipped or punched. Specifically, this can be implemented as follows:

[0274] In one embodiment, assuming that the third resource unit set of the first type or the third resource unit set of the second type includes X resource units / groups of resource units, and the second frequency domain resource of the first type or the second frequency domain resource of the second type includes a maximum of N resource units / groups of resource units, then a mapping pattern based on the interleaving mode between the second frequency domain resource of the first type and the second frequency domain resource of the second type can be generated according to the maximum N resource units / groups of resource units of the first type and the maximum N resource units / groups of resource units of the second type.

[0275] Among them, the mapping pattern based on the interleaving mode is used for the mapping between N resource units / resource unit groups in the second frequency domain resources of the first type and N resource units / resource unit groups in the second frequency domain resources of the second type.

[0276] In some examples, if a resource element / resource element group (index n) in a subset of second frequency domain resources of the first type has a mapping relationship with a resource element / resource element group (index p) in a third resource element set of the second type, the UE can skip a resource element / resource element group in the third resource element set of the second type and map it to a resource element / resource element group that has a mapping relationship with a fourth resource element / resource element group of the first type, or map it to a fourth resource element / resource element group of the second type, according to the mapping pattern based on the interleaving mode.

[0277] Among them, the second type of frequency domain resources corresponding to the fourth resource unit / fourth resource unit group of the first type are the resource units / resource unit groups in the second frequency domain resources other than the third resource unit set of the second type;

[0278] Among them, the fourth resource unit / fourth resource unit group of the second type is the resource unit / resource unit group in the second frequency domain resources other than the third resource unit set of the second type.

[0279] In some examples, the fourth resource unit / group of the first type is a resource unit / group of resources in a subset of the second frequency domain resources of the first type; wherein the index of the fourth resource unit / group of the first type is not less than and is closest to the index of a resource unit / group of resources in a subset of the second frequency domain resources of the first type, and the resource unit / group of the first type corresponding to the index of a resource unit / group of resources in a subset of the second frequency domain resources of the first type has no mapping relationship with any resource unit / group of resources in the third resource unit set of the second type. Wherein, the available resource units / indices of the second frequency domain resources of the first type are non-contiguous, and / or the available resource units / indices of the second frequency domain resources of the second type are contiguous; wherein, the available resource units of the second frequency domain resources of the first type and the available resource units of the second frequency domain resources of the second type are determined based on X resource units / groups of resources and a maximum of N resource units / groups of resources.

[0280] In some examples, the fourth resource unit or group of fourth resource units of the second type is a resource unit / group of resource units in the second frequency domain resource of the second type.

[0281] The index (index t) of the fourth resource unit / fourth resource unit group of the second type includes at least one of the following:

[0282] The index of the end resource unit / end resource unit group that is not less than and is closest to the first frequency domain resource of the second type;

[0283] The index of the end resource unit / end resource unit group that is not greater than the first frequency domain resource of the second type;

[0284] If there is a mapping relationship with the resource unit / resource unit group (index n-1) in the subset of the adjacent first type second frequency domain resource, the index of the resource unit / resource unit group of the second type second frequency domain resource is incremented by one;

[0285] If there is a mapping relationship with the resource unit / resource unit group (index n-2) in the subset of the two adjacent first type second frequency domain resources, the index of the resource unit / resource unit group of the second type second frequency domain resource is incremented by one;

[0286] Among them, the fourth resource unit / fourth resource unit group of the second type includes only the resource unit / resource unit group of the second type of frequency domain resources that has a mapping relationship with one resource unit / resource unit group in the subset of the second frequency domain resources of the first type.

[0287] Wherein, the available resource units / available resource unit indices of the second frequency domain resources of the first type are continuous, and / or the available resource units / available resource unit indices of the second frequency domain resources of the second type are non-contiguous; wherein, the available resource units of the second frequency domain resources of the first type and the available resource units of the second frequency domain resources of the second type are determined based on X resource units / resource unit groups and a maximum of N resource units / resource unit groups.

[0288] In some examples, with This indicates the maximum number of resource units for either the second frequency domain resource of the first type or the second frequency domain resource of the second type. This indicates the starting resource unit index of a second frequency domain resource of type 1 or a second frequency domain resource of type 2. This represents the maximum number of resource units for either the first type of first-frequency domain resource or the second type of first-frequency domain resource. or This indicates the starting resource unit index of the first frequency domain resource of type 1 or the first frequency domain resource of type 2; RB bundle indicates a resource unit group; L i This indicates the number of resource units in the resource unit group of the second frequency domain resource, where RB is the resource unit.

[0289] Then, in response to the first condition, the UE receives at least one of the following: PDSCH frequency domain resource allocation information indicated by DCI, Rate Match indication information, and VRB to PRB interleaving mode indication information, and activates BWP#i containing... There are RBs, and the starting RB position is... The initial BWP includes There are RBs, and the starting RB position is... or The first resource set is defined to include the RE resources not used for PDSCH transmission as indicated in the Rate Match pattern, and the set of PRB or RE resources corresponding to CORESET0. At least one of them. The information is data or complex numerical symbols transmitted or carried by the PDSCH. Based on A resource RB is divided into N RB bundles. The mapping method from VRB to PRB can include at least one of the following:

[0290] 1) According to the VRB to PRB interleaving pattern, punch or set the information mapped to the first PRB bundle to 'Null', or punch or set the information mapped to the PRB in the first resource set to 'Null', or punch or set the information on the VRB resource corresponding to the VRB bundle that has a mapping relationship with the first PRB bundle to 'Null', or punch or set the information on the VRB or the RE corresponding to the VRB that has a mapping relationship with the PRB or RE in the first resource set to 'Null'; wherein, the first PRB bundle is a PRB bundle that includes at least one PRB or RE in the first resource set.

[0291] 2) According to the VRB to PRB interleaving pattern, information will skip mapping or not map to the VRB resources corresponding to the VRB bundle that is mapped to the first PRB bundle, or information will not map to the VRB or the RE corresponding to the VRB that is mapped to the RB or RE in the first resource set.

[0292] 3) If, according to the VRB to PRB interleaving pattern, VRB bundle n and PRB bundle m have a mapping relationship, and at least one PRB or RE in PRB bundle m is in the first resource set, then the information on VRB bundle n will be mapped to the RE resource corresponding to PRB bundle m1. Here, PRB bundle m1 can be at least one of the following:

[0293] a. If the PRB bundle size is a value other than 'wideband', then PRB bundle m1 is the number of the first PRB bundle that does not include PRBs in the first resource set among PRB bundles with a number greater than m, or PRB bundle m1 does not include PRBs in the first resource set, and it has a mapping relationship with VRB bundle n+x, where x is greater than 0 or less than 0.

[0294] b. If the PRB bundle size is a value other than 'wideband' and n is even, then PRB bundle m1 is the number of the first PRB bundle among the PRB bundles with numbers greater than m, excluding the PRBs in the first resource set, and / or m1 is an integer value greater than m and less than N / 2, and there is a mapping relationship between PRB bundle m1 and VRB bundles with even numbers.

[0295] c. If the PRB bundle size is a value other than 'wideband' and n is odd, then PRB bundle m1 is the number of the first PRB bundle (excluding PRBs in the first resource set) among PRB bundles with numbers greater than m, and / or m1 is an integer value greater than N / 2 and not greater than N-1, and there is a mapping relationship between PRB bundle m1 and VRB bundles with odd numbers.

[0296] d. If the PRB bundle size is a value other than 'wideband', then there is a mapping relationship between PRB bundle m1 and VRBbundle n+x, where VRB bundle n+x.

[0297] e. If the PRB bundle size is configured as 'wideband', then PRB bundle m1 is PRB bundle m, where VRB bundle n has a mapping relationship with PRB n1, where PRB n1 is the RB in the first resource set, and the information on VRB n1 will be mapped to PRB n1+δ, where n1 is... or δ is Alternatively, n1 is an integer not less than 0 and not greater than N-1, and n1+δ is an integer not less than... Integers.

[0298] In some examples, such as when the first resource set is an overlapping PRB or RE resource of the initial BWP and the activating BWP, the first resource set includes If there are PRB resources, then the resource distribution in the first resource set includes at least one of the following:

[0307] In some examples, according to the VRB to PRB interleaving pattern, when VRB bundle j corresponds to a PRB bundle in the overlapping part, the UE skips the PRB bundle h in the overlapping part by default and maps it to the PRB bundle position corresponding to VRB bundle j+R or VRBbundle j+L. Here, R is 2, and L is the size of the VRB to PRB interleaving unit on the active BWP#i, i.e., the maximum number of PRBs in a PRB bundle.

[0308] In some examples, if When VRB bundle 0 is assigned to PDSCH for transmission, if PRB bundle 0 on the active BWP i overlaps with the PRB of the initial BWP, then the information on VRB bundle 0 is either punched or not transmitted, or it is assumed that VRB bundle 0 is mapped to the active BWP i including PRB number...

This indicates the starting resource unit index of a second frequency domain resource of type 1 or a second frequency domain resource of type 2. This represents the maximum number of resource units for either the first type of first-frequency domain resource or the second type of first-frequency domain resource. or This indicates the starting resource unit index of the first frequency domain resource of type 1 or the first frequency domain resource of type 2; RB bundle indicates a resource unit group; L i This indicates the number of resource units in the resource unit group of the second frequency domain resource, where RB is the resource unit.

[0330] Then, in response to the first condition, the UE receives at least one of the following: PDSCH frequency domain resource allocation information indicated by DCI, Rate Match indication information, and VRB to PRB interleaving mode indication information, and activates BWP#i containing... There are RBs, and the starting RB position is... The initial BWP includes There are RBs, and the starting RB position is... or The scheme for determining the number of VRBs that DCI can schedule based on the number of PRB / RE resources overlapping with the initial BWP in the live BWP#i includes at least one of the following:

[0331] 1) If the maximum number of schedulable VRBs for DCI is The maximum number of available VRBs is The following situations may occur:

[0332] a. The number of VRBs scheduled by DCI is S, where S VRBs include δ RB resources from the first resource set; where information skips the mapping of δ VRBs or is not mapped to δ VRBs, or the RE resources corresponding to δ VRBs are filled with 'Null' or predefined or known values, such as '0' or '1' or the modulation symbols corresponding to data '0' and '1'. Wherein, according to the VRB toPRB interleaving pattern, δ VRBs have a mapping relationship with PRBs in the first resource set.

[0333] b. The number of VRBs scheduled by DCI is S, where S VRBs correspond to S PRBs, and are divided into X VRB / PRB bundles. The X PRB bundles include δ PRB bundles that include at least one RB resource from a first resource set. Information skips the mapping of δ VRB bundles or is not mapped to δ VRBs, or the RE resources corresponding to the δ VRB bundles are filled with 'Null', predefined values, or known values, such as '0' or '1', or the modulation symbols corresponding to data '0' and '1'. According to the VRB to PRB interleaving pattern, the δ VRB bundles have a mapping relationship with at least one PRB or PRB bundle from the first resource set.

[0334] c. DCI indicates δ or or The starting position and number or length of each VRB / PRB on the activated BWP#i.

[0335] The DCI carries a bitmap to indicate whether each VRB / VRB bundle or PRB / PRB bundle in the current schedule or initial BWP is mappable to valid information or is available. Specifically, when a bit in the bitmap is 1, the corresponding VRB / VRB bundle or PRB / PRB bundle resource is unschedulable or cannot be mapped to valid information; when a bit in the bitmap is 0, the corresponding VRB / VRB bundle or PRB / PRB bundle resource is schedulable or can be mapped to valid information. In some embodiments, the UE knows the starting RB position of the initial BWP.

[0336] Alternatively, the DCI carries a RIV to indicate VRB or PRB resources that are not mappable or available in the current schedule or initial BWP. The RIV is based on the number (N) or δ of RBs or RB bundles in the initial BWP or active BWP#i. The starting position (n) of a VRB / PRB or VRB bundle / PRB bundle and the number of RBs or RB bundles (m) are determined. Wherein, if m-1 is not greater than func(N / 2), then Q = N(m-1) + n; otherwise, Q = N(N-m+1) + (N-1-n).

[0337] 2) If the maximum number of schedulable VRBs for DCI is or The following situations may occur:

[0338] a. The maximum schedulable number of VRBs corresponds to a segment of VRB resources with consecutive RB indices, and / or a segment of consecutive PRB resources, wherein a segment of consecutive PRB resources is the PRB resources on the active BWP#i that do not include the first resource set. For example, the bandwidth size of the active BWP#i is 275 RBs, and the number of overlapping RBs between the initial BWP and the active BWP is 36, i.e. Therefore, the DCI-schedulable VRB resources are 275 - 36 = 239 RBs. For example, the bandwidth of activating BWP#i is 275 RBs, and the number of overlapping RBs between the initial BWP and the activated BWP is 36, i.e. The current DCI needs to schedule 200 valid RB resources. Among the 200 valid RB resources, there are 18 RBs on the initial BWP. Therefore, the VRB resources that the DCI can schedule are 200-18=182 RBs.

[0339] b. Generate a VRB toPRB interleaving pattern between the schedulable VRB resources and the PRB resources on the activated BWP#i that do not include the first resource set; or divide the PRB bundles only for the PRB resources on the activated BWP#i that do not include the first resource set, and generate a VRB toPRB interleaving pattern between the VRB bundles corresponding to the scheduled VRB resources and the PRB bundles; or perform VRB toPRB mapping between the schedulable VRB resources and the PRB resources on the activated BWP#i that do not include the first resource set according to the VRB toPRB interleaving pattern.

[0340] c. The DCI indicates I frequency domain resource allocation indication subfields, where each subfield indicates the start position of an RB and a contiguous segment of RB resources. I is an integer not less than 0, and I is not less than 1 when the first resource set includes at least one RB, or when the available VRB resources schedulable by the DCI are discontinuous, or when the Rate Match indicator indicates at least one Rate Match pattern / group. When I is not less than 1, the original frequency domain resource allocation indication field includes I frequency domain resource allocation indication subfields, each indicated via RIV. For example, if the DCI needs to schedule 200 valid RBs for PDSCH transmission, and the initial BWP and the activated BWP#i have overlapping RB positions numbered 101–136, then the DCI indicates two frequency domain resource allocation subfields: RB resources numbered 0–100 and RB resources numbered 137–235.

[0341] In some examples, for a PDSCH allocated S VRBs, if a portion of the VRBs indicated by the DCI will be mapped to resources in the overlapping portion, and the DCI indicates an additional δ consecutive VRBs, it must be guaranteed that S VRBs out of X VRB bundles can be mapped to PRBs outside the overlapping portion, where X is the number of PRB bundles mapped to by S+δ consecutive VRBs. For example, if the PDSCH is scheduled with X0 VRB bundles according to the VRB to PRB interleaving pattern, where X0 / 2 VRB bundles will be mapped to PRB bundles n to n+m, then the DCI indicates X0+X0 / 2 consecutive VRB bundles. Figure 9 An example diagram illustrating the mapping relationship between VRB and PRB provided in this application embodiment is shown below. Figure 9 As shown, based on the VRB toPRB interleaving pattern, δ VRB indicators are added, and (S+δ) VRBs are indicated by DCI. The UE determines the implementation method of the VRBs allocated to the PDSCH that can be used for PDSCH transmission based on the DCI indicator information. The shaded blocks represent VRB bundles with invalid / skipped DCI indicators.

[0342] In some examples, when n+m<N / 2, the DCI does not indicate VRB bundles with even indices between VRB bundle R*n and VRB bundle R*(n+m). For example, when n=0 and the overlapping portion of the initial BWP and the active BWP corresponds to PRB bundle 0 to PRB bundle m, the DCI does not indicate VRB bundles with even indices between VRB bundle 0 and VRB bundle 2m. Figure 10 is a schematic diagram of an example of a VRB to PRB mapping relationship provided in the embodiments of the present application, as Figure 10 shown, assuming N is an even number, the mapping relationship of the VRB to PRB interleaving mode is illustrated therein. The shaded blocks are VRB bundles that are indicated as invalid / skipped by the DCI.

[0343] In some examples, when n≥N / 2, the DCI does not indicate VRB bundles with odd indices between VRB bundle R*n and VRB bundle R*(n+m) or VRB bundle N-1; or among the VRB resources indicated by the DCI, the VRB bundles with odd indices between VRB bundle R*n and VRB bundle R*(n+m) or VRB bundle N-1 are invalid VRB resources. For example, n=N-1-m, and when the overlapping portion of the initial BWP and the active BWP corresponds to PRB bundle N-1-m to PRB bundle N-1, the DCI does not indicate VRB bundles with odd indices between VRB bundle 2(N-1-m) and VRB bundle N-1. Figure 11 is a schematic diagram of an example of a VRB to PRB mapping relationship provided in the embodiments of the present application, as Figure 11 shown, assuming N is an even number, the mapping relationship of the VRB to PRB interleaving mode is illustrated therein. The shaded blocks are VRB bundles that are indicated as invalid / skipped by the DCI.

[0344] In some examples, when n<N / 2 and n+m≥N / 2, the DCI does not indicate VRB bundles with even indices among VRB bundle 2n to VRB bundle N-1, and the DCI does not indicate VRB bundles with odd indices among VRB bundle 1 to VRB bundle 2(n+m); or among the VRB resources indicated by the DCI, the VRB bundles with even indices among VRB bundle 2n to VRB bundle N-2 and the VRB bundles with odd indices among VRB bundle 1 to VRB bundle 2(n+m) belong to invalid VRB resources. Figure 12 is an exemplary diagram of a VRB to PRB mapping relationship provided in the embodiments of the present application, as shown in Figure 12 , assuming N is an even number, the mapping relationship of the VRB to PRB interleaving mode is illustrated therein. The shaded blocks are VRB bundles that the DCI indicates as invalid / skipped.

[0345] In some examples, the number of RBs or the RB positions occupied by the downlink initial BWP in a cell or each activated BWP is configured by a new higher-layer parameter compared to 5G NR release 19, which defines the PRB bundle index n and the number of consecutive PRB bundles m on activated BWP i. If the frequency domain resource allocation indication field in the DCI indicates S consecutive VRBs, the DCI further indicates, by means of a bitmap indication, whether each of the S VRBs is a valid VRB resource, or whether the VRB to PRB mapping is skipped / ignored before VRB to PRB interleaving, or whether the VRB to PRB mapping is skipped / ignored after VRB to PRB interleaving, or whether it can be used for PDSCH transmission. The S pieces of VRB validity indication information are indicated by a bitmap, with each bit corresponding to the state of one VRB, or each bit corresponding to the state of one VRB bundle, or each bit corresponding to the state of R VRBs in one VRB bundle. Figure 13 is an exemplary diagram of a VRB to PRB mapping relationship provided in the embodiments of the present application, as shown in Figure 13 , which illustrates an implementation manner in which the DCI indicates S VRBs and indicates VRB bundles that cannot be used for PDSCH transmission among X VRB bundles corresponding to the S VRBs. The shaded blocks are VRB bundles that the DCI indicates as invalid / skipped.

[0346] In some examples, the DCI indicates the starting PRB bundle number n and the number of consecutive PRB bundles m corresponding to the overlapping resources. The indication of n and m uses the same method as the resource indicator value (RIV) of the DCI in 5G NR release 15. If m-1 is not greater than func(N / 2), then Q = N(m-1) + n; otherwise, Q = N(N-m+1) + (N-1-n). Where N is the number of PRB bundles corresponding to the activated BWP when the RB bundle is L or R, or the number of PRB bundles corresponding to the activated BWP minus 1, or the maximum number of PRB / VRB bundles that the base station can configure for the UE, or the maximum number of PRB / VRB bundles that the base station can configure for the UE minus 1.

[0347] In some examples, the new higher-layer parameter configuration compared to 5G NR release 19 indicates the PRB or RE location of the initial BWP within the active BWP, where each bit corresponds to one PRB bundle or one PRB, and the indication information adopts per BWP configuration. Based on the PRB location for initial BWP transmission within the active BWP indicated by the new higher-layer parameter configuration compared to 5G NR release 19, as well as the frequency domain resource allocation information and VRB to PRB mapping information indicated by DCI, the VRB to PRB mapping pattern is determined, and the UE ignores or skips the resources of the overlapping part between the initial BWP and the active BWP i during VRB to PRB mapping or demapping.

[0348] In some examples, DCI indicates the starting PRB bundle number n and the number of consecutive PRB bundles m corresponding to the overlapping resources. PRB bundle n to PRB bundle n+m-1 are not numbered, and the original PRB bundle n+m is redefined as PRB bundle n, with subsequent indices modified accordingly; wherein the PRB numbers contained in the original PRB bundle n+m satisfy at least one of the following conditions: 1) The PRB numbers contained in the original PRB bundle n+m are greater than any PRB number in the overlapping portion of the initial BWP and the active BWP i; 2) The difference between the PRB numbers contained in the original PRB bundle n+m and the maximum PRB number in the overlapping portion of the initial BWP and the active BWP i does not exceed L or R.

[0349] Solution 5: A distributed scheme for generating VRB to PRB interleaving patterns is presented. Specifically, it can be implemented as follows:

[0350] In one embodiment, the configuration information for the second type of control signaling may include at least one of the following:

[0351] The relevant information of the second frequency domain resources of the first type; wherein, the relevant information of the second frequency domain resources of the first type is used to indicate at least one of the following: the total number of resource units, the total number of resource unit groups, the index, the start position, and the end position of the second frequency domain resources of the first type;

[0352] The relevant information of the second type of second frequency domain resources; wherein, the relevant information of the second type of second frequency domain resources is used to indicate at least one of the following: the total number of resource units, the total number of resource unit groups, the index, the start position, and the end position of the second type of second frequency domain resources;

[0353] A mapping pattern based on interleaving mode between the first type of frequency domain resources and the second type of frequency domain resources.

[0354] In some examples, the interleaving-based mapping pattern between the first type of frequency domain resources and the second type of frequency domain resources includes at least one of the following:

[0355] The mapping pattern based on the interleaving mode between the total resource unit / total resource unit group of the first type of second frequency domain resources configured based on the second type of control signaling;

[0356] Based on the second type of control signaling configuration, the mapping pattern between resource units in a resource unit group of the first type of second frequency domain resources and resource units in a resource unit group of the second type of second frequency domain resources based on the interleaving mode.

[0357] In some examples, the first type of control signaling is DCI, and the second type of control signaling is RRC signaling. The second frequency domain resource indicated by the second type of control signaling is the resource element activating BWP#i. The size of the resource element group indicating the second frequency domain resource activating BWP#i is RBG size and PRB bundle size. The interleaving-based mapping pattern generated by the total resource elements / resource element groups of the second frequency domain resource configured based on RRC is the first interleaving-based mapping pattern. The interleaving-based mapping pattern generated by the resource elements in a resource element group of the second frequency domain resource configured based on RRC signaling is the second interleaving-based mapping pattern. The interleaving unit of the first interleaving-based mapping pattern is L1 resource element groups, and the interleaving unit of the second interleaving-based mapping pattern is L2 resource elements, where L2 is not greater than the total number of resource elements in a resource element group.

[0358] In some examples, the UE will determine the first type of second frequency domain resources and the second type of second frequency domain resources related to PDSCH transmission based on the DCI indication information, determine the first interleaving mode-based mapping pattern based on the RRC signaling configuration information and the total number of resource elements of the second frequency domain resources, and determine the second interleaving mode-based mapping pattern based on the RRC signaling configuration information and the number of resource elements in a resource element group of the second frequency domain resources.

[0359] In response to the first condition, the UE completes the mapping of resource unit groups in the second frequency domain resources of the first type to resource unit groups in the second frequency domain resources of the second type according to the first mapping pattern based on the interleaving mode; or, the UE completes the mapping of resource units in a resource unit group in the second frequency domain resources of the first type to resource units in a corresponding resource unit group in the second frequency domain resources of the second type according to the second mapping pattern based on the interleaving mode.

[0360] The RRC configuration includes at least one of the following: the number of resource units activated by BWP#i, the resource unit group size, the RBG size, the PRBbundle size, and the interleaving unit of the first-level interleaving mode.

[0361] The second higher-level parameter configuration includes the number and location of resource units activating BWP#i, the size of the resource unit group, and the interleaving unit of the second-level interleaving mode.

[0362] The third higher-level parameter configuration includes at least one of the following: the number and location of resource units activating BWP#i, the number and location of resource units of the initial BWP, the first-level interleaving mode enable or disable indication, and the second-level interleaving mode enable or disable indication.

[0363] Understandably, this solution is suitable for DCI scheduling of extremely large bandwidths. For downlink PDSCH transmission, a distributed VRB to PRB interleaving mode can be defined to avoid the problem of PDSCH code rate exceeding the decodeable threshold due to the joint configuration of VRB to PRB interleaving mode and Rate Match pattern when there are fewer VRBs scheduled. Simultaneously, local frequency domain diversity gain can be obtained. For downlink PDSCH transmission, the UE determines the first-level interleaving unit of VRB to PRB as RBG size or RB bundle size based on the RBG size or PRB bundle size (N1) configured by the higher-layer parameters. The UE determines the second-level interleaving unit of VRB to PRB as the value configured by the VRB to PRB interleaving mode based on the VRB to PRB interleaving mode configured by the higher-layer parameters.

[0364] The mapping relationship between VRB j and PRB f(j) in the N1 consecutive VRB resources included in the first-level interleaving mode is as follows:

[0365] f(j) = rC1 + c

[0366] j = cR1 + r

[0367] r = 0, 1, ..., R1-1

[0368] c = 0, 1, ..., C1-1

[0369]

[0370] Where R1 is a predefined value, or a value determined based on N1. For example, or or And R1 is an integer.

[0371] The second-level interleaving mode includes The mapping relationship between one VRBG or VRB bundle j and N PRBGs or PRB bundles f(j) is as follows:

[0372] f(j) = rC + c

[0373] j = cR + r

[0374] r = 0, 1, ..., R-1

[0375] c = 0, 1, ..., C-1

[0376]

[0377] in, Where R is a predefined value, or a value determined based on N. For example, or or And R is an integer.

[0378] In some examples, for DCI scheduling of ultra-large bandwidth In the case of PDSCH transmission, the candidate interleaving unit of the VRB to PRB interleaving mode can be redefined to reduce interleaving complexity while ensuring reliability. For RA type 0, higher-layer signaling can configure the VRB to PRB interleaving mode, and the DCI indicates whether it is used for PDSCH transmission.

[0379] In this context, the interleaving unit candidate value for the VRB to PRB interleaving mode configurable in higher-layer signaling is the value of RBG size(P). The RBG size is 2. n Or 3*2 n Where n is not less than 5 and not greater than 8.

[0380] The VRB to PRB interleaving unit L and / or RB bundle size used in PDSCH transmission should be equal to or greater than the RBG size(P) of the BWP application in which the PDSCH transmission is located, or should be an integer multiple of the RBG size(P) of the BWP application in which the PDSCH transmission is located.

[0381] Specifically, when the activated BWP x (divided into N PRB bundles) overlaps with the initial BWP, the DCI does not schedule the RBG containing the overlapping frequency domain resources for PDSCH transmission.

[0382] When the active BWP x (divided into N PRB bundles) overlaps with the initial BWP, if the position of the PRB bundle x mapped after the VRB bundle n is at the position where the active BWP i overlaps with the initial BWP, then the PRB bundle x is not numbered, or the PRB bundle x+1 that is adjacent to the PRB bundle and has a larger number is set as the PRB bundle x, where x is greater than 0 and not greater than N-2.

[0383] In some examples, Figure 14 This is an example diagram of an interleaving pattern provided in an embodiment of the present application, which shows an interleaving pattern in which a first resource set and a second resource set perform an interleaving pattern to map resource units in the first resource set to resource units in the second resource set according to a first-level interleaving mode.

[0384] In some examples, Figure 15 This is an example diagram of an interleaving pattern provided in an embodiment of the present application, showing an interleaving pattern in which a first resource set and a second resource set perform an interleaving pattern to map resource units in the first resource set to resource units in the second resource set according to a first-level interleaving mode and a second-level interleaving mode.

[0385] Option 6: Determine the first frequency domain resources and a subset of the second frequency domain resources based on the configuration information of the second type of control signaling and the indication information of the first type of control signaling; wherein the second frequency domain resources include the third resource unit set. Based on a specific value (λ), determine the number of PRBs (n) used to calculate the TBS. PRB ) or number of REs (N) RE), transport block size (TBS), median TBS (N) info The code rate or modulation order and number of layers corresponding to the modulation and coding scheme (MCS) are corrected to determine the final TBS value. A specific value is related to at least one of the following: the number of resource units belonging to the third resource unit set included in the subset of second frequency domain resources; the total number of resource units in the subset of second frequency domain resources; the number of RE / RBs configured in the rate matching pattern that are not available for PDSCH transmission; and the total number of resource units included in the subset of second frequency domain resources that are not available for PDSCH transmission. Specifically, one specific value is the ratio of the number of resource units in the third resource unit set included in the subset of second frequency domain resources to the total number of resource units in the subset of second frequency domain resources; the ratio of the number of RE / RBs configured in the rate matching pattern that are not available for PDSCH transmission to the total number of RE / RBs in the subset of second frequency domain resources; and the ratio of the number of RBs configured in the rate matching pattern that are not available for PDSCH transmission to the total number of RBs in the active BWP. The correction includes a first specific value and n. PRB N RE Bit rate, modulation order, number of layers, N info Perform at least one of the following operations between TBS: multiplication, division, addition, conditional judgment, splitting, rounding up, rounding down, rounding to the nearest integer, and modulo.

[0386] In some embodiments, n PRB '=f(n PRB ,λ) represents n PRB '=func(n PRB *λ), where λ is a real number greater than 0 and not greater than 1, and func() represents at least one of the following operations on the input data: rounding up, rounding down, rounding to the nearest integer, or retaining the original value.

[0387] In some embodiments, a correction operation is performed when the number of resource units in the third resource unit set, the number of resource units belonging to the third resource unit set included in the subset of the second frequency domain resources, the total number of resource units in the subset of the second frequency domain resources, the number of REs / RBs configured in the rate matching pattern that are not available for PDSCH transmission, or the total number of resource units not available for PDSCH transmission included in the subset of the second frequency domain resources are not less than a first threshold. The first threshold is not less than 10% of the total number of RBs in the active BWP or the number of RBs in the subset of the second frequency domain resources. In this embodiment, the value of the first threshold takes into account that the difference between the spectral efficiency values ​​corresponding to adjacent MCSs in the MCS table is not less than 0.1. Therefore, in order to better match the MCSs indicated by the DCI for PDSCH transmission, a correction operation is required when the first threshold is exceeded.

[0388] In some embodiments, a correction operation is performed when a first specific value is not less than a second threshold. The second threshold is not less than 0.08.

[0389] In this exemplary embodiment, when the frequency domain resources scheduled by DCI for PDSCH transmission include resource units that cannot be used for PDSCH transmission, the relevant parameters used to determine the transport block size are adjusted by configuring a specific value or determining a specific value according to the relevant frequency domain resource indication information, so as to achieve the effect of matching the actual code rate of PDSCH transmission with the indicated MCS.

[0390] Option 7: Determine a subset of the second frequency domain resources based on the configuration information of the second type of control signaling and the indication information of the first type of control signaling; divide the resource units in the subset of the second frequency domain resources into one or more resource unit groups based on the starting position and number of resource units in the subset; generate a sixth specific pattern based on the indices of one or more resource unit groups of the first type of second frequency domain resources and the indices of one or more resource unit groups of the second type of second frequency domain resources; and determine the mapping relationship between the first type of resource unit groups and the second type of resource unit groups in the subset of the second frequency domain resources according to the sixth specific pattern. Wherein, the resource unit / resource unit group index in the sixth specific pattern is within the range of the resource unit / resource unit group indexes in the subset of the second frequency domain resources, and the number of resource units included in the sixth specific pattern is equal to the number of resource units in the subset of the second frequency domain resources.

[0391] In this exemplary embodiment, by narrowing or pre-selecting the range of resources that can participate in interleaving mapping, the purpose of avoiding resource collisions is achieved. This solution does not need to consider whether there are resource units that cannot be used for PDSCH transmission in the frequency domain resources scheduled by DCI for PDSCH transmission.

[0392] Option 8: Determine a subset of the second frequency domain resources based on the configuration information of the second type of control signaling and the indication information of the first type of control signaling; wherein the second frequency domain resources include a third resource unit set. In response to the first condition, adopt the mapping pattern generation scheme based on the interleaving mode from Option 1, Option 2, Option 3, or Option 7, or the VRB-to-PRB mapping process based on the interleaving of frequency domain resources scheduled by DCI; otherwise, adopt the conventional mapping pattern generation scheme based on the interleaving mode or the interleaved VRB-to-PRB mapping process. The first condition includes that the subset of the second frequency domain resources includes one or more resource units from the third resource unit set.

[0393] In this exemplary embodiment, in the case where there are resource elements in the frequency domain resources scheduled by DCI for PDSCH transmission that cannot be used for PDSCH transmission, in response to the first condition, the range of resources that can participate in interleaving mapping is narrowed to avoid resource collisions; for other cases, the scheme of generating a mapping pattern based on the interleaving mode in the entire active BWP is still adopted. This scheme has good forward compatibility.

[0394] Option 9: Determine the second frequency domain resources and subsets of the second frequency domain resources based on the configuration information of the second type of control signaling and the indication information of the first type of control signaling; divide the resource units in the second frequency domain resources or subsets of the second frequency domain resources into multiple resource unit parts, where one or more resource units do not form a resource unit group; generate a seventh specific pattern using the resource units within a resource unit group; and determine the mapping relationship between the first type of resource units and the second type of resource units within a resource unit group according to the seventh specific pattern. Each resource unit part includes a continuous segment of resource units, and a resource unit group includes one or more discrete resource unit parts. One or more resource unit parts are divided into a resource unit group according to the equal interval principle of the resource unit part indices. The indices of the resource units within the first type of resource unit group are interleaved using an (m x n)-dimensional interleaver according to the principle of row-wise or column-wise interleaving to obtain the corresponding indexes of the resource units within the second type of resource unit group. The product of m and n is the number of resource units within a resource unit group, where m is the interleaving depth. For example, if the interleaving depth of the row list interleaver is 2, and the 16 RBs are divided into 8 resource unit parts, according to the principle of equal interval of the index, the resource unit parts with indices 0, 2, 4, and 6 are divided into one resource unit group, and the resource unit parts with indices 1, 3, 5, and 7 are divided into another resource unit group. The resource unit indices in the first resource unit group are {0, 1, 4, 5, 8, 9, 12, 13}. The resource units with indices {0, 1, 4, 5, 8, 9, 12, 13} in the first resource unit group of the first type are mapped to the resource units with indices {0, 8, 1, 9, 4, 12, 5, 13} in the first resource unit group of the second type.

[0395] This exemplary embodiment proposes a method based on discrete resource unit grouping, and using the resource units within the group to generate an interleaving-based mapping pattern. This scheme can easily skip resource units unusable for PDSCH transmission during the resource unit partitioning process, and obtain frequency domain diversity gain through intra-group interleaving mapping operations, thereby avoiding resource collisions, improving scheduling flexibility, and enhancing transmission reliability.

[0396] In one exemplary implementation Figure 16 This is a schematic diagram of the structure of a signal processing device provided in an embodiment of this application, as shown below. Figure 16 As shown, the device includes:
