[0049] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] To achieve integrated communication and sensing capabilities for base stations, base stations need to send messages for communication and simultaneously receive sensing messages for sensing. Therefore, base stations need to be able to send and receive messages simultaneously, meaning they must have FD communication capabilities. However, FD communication introduces additional factors that affect communication quality, such as SI (self-interference), inter-cell crosstalk, and inter-user interference. SI is the most serious of these factors. To suppress SI, related technologies combine RF (radio frequency) passive SI suppression, analog domain active SI cancellation, and digital domain active SI cancellation to ensure full-duplex communication performance. However, from a practical application perspective, these SI suppression technologies increase the complexity of base stations and user terminals. Therefore, it is necessary to achieve FD while simultaneously suppressing SI and reducing the complexity of base stations and user terminals. In this context, SBFD is a feasible solution for implementing FD.

[0051] First, we will explain the configuration of SBFD time domain resources in current related technologies. In 5G (5th Generation Mobile Communication Technology) systems, the TDD (Time Division Duplex) frame structure is divided into UL slots, DL slots, and S slots based on time slots. Symbols in S slots can be configured as UL symbols, DL symbols, and F (Flexible) symbols. F symbols can be used as UL symbols, DL symbols, or GP (Guard Period) symbols.

[0052] The base station can inform the UE of the configured TDD frame structure through RRC (Radio Resource Control) signaling in a semi-static configuration mode. The RRC signaling may include TDD-UL-DL-ConfigCommon (Time Division Duplex-UpLink-DownLink-ConfigurationCommon, time division duplex-uplink-downlink-common configuration) or TDD-UL-DL-ConfigDedicated (Time Division Duplex-UpLink-DownLink-ConfigurationDedicated, time division duplex-uplink-downlink-dedicated configuration). The former can configure the TDD frame structure at the cell level, and the latter can configure the UE-specific TDD frame structure for a specific UE. In TDD-UL-DL-ConfigCommon, a maximum of two TDD frame structure patterns can be configured. Each TDD frame structure pattern can configure the period of the TDD frame structure, and specifically configure each symbol in the TDD frame structure as a DL symbol, a UL symbol or an F symbol. If there is a TDD frame structure pattern, the TDD frame structure pattern directly configures the TDD structure. If there are two TDD frame structure patterns, the two TDD frame structure patterns can together configure the overall frame structure of TDD.

[0053] The period of the TDD frame structure is configured by the dl-UL-TransmissionPeriodicity (DownLink-UpLink-TransmissionPeriodicity, downlink-uplink-transmission period) parameter in the TDD frame structure pattern. If there is a TDD frame structure pattern, the TDD frame structure period is the period configured in the TDD frame structure pattern, and the period can be represented by P1. If there are two TDD frame structure patterns in T, the TDD frame structure period is the sum of the periods configured in the two TDD frame structure patterns, and the sum of the periods can be represented by P1+P2. P1 and P2 are the periods configured in the two TDD frame structure patterns respectively.

[0054] FIG1 is a schematic diagram of a frame structure provided by an embodiment of the related technology.

[0055] The diagram includes five time slots, 0-4, each of which contains 14 symbols, 0-13. The symbol DL in the diagram indicates that the corresponding symbol is a DL symbol used to transmit downlink data, while the symbol UL in the diagram indicates that the corresponding symbol is a UL symbol used to transmit uplink data. Time slot 3 in the diagram is an S-slot. Symbols 0-9 in the S-slot are configured as DL symbols, symbols 12-13 are configured as UL symbols, and symbols 10-11 are configured as F symbols, serving as GP symbols for uplink and downlink switching. The uplink-downlink ratio in the diagram is approximately 1:4.

[0056] In addition, the base station can further change the F symbol configured in TDD-UL-DL-ConfigCommon through the parameters included in TDD-UL-DL-ConfigDedicated, and can further configure it into a DL symbol or a UL symbol.

[0057] Based on this, the current 3GPP (3rd Generation Partnership Project) standardization process has led to the following conclusions regarding SBFD time domain resource allocation:

[0058] For UEs in RRC connected mode, SBFD time domain resources are configured in a period. When at least one TDD frame structure pattern is configured, the period of SBFD time domain resources can be selected from the following options:

[0059] Option 1: The period of the SBFD time domain resource is the same as the period of the TDD frame structure configured by dl-UL-TransmissionPeriodicity in TDD-UL-DL-ConfigCommon.

[0060] Option 2: The period of the SBFD time domain resource is an integer multiple greater than 1 of the period of the TDD frame structure configured by dl-UL-TransmissionPeriodicity in TDD-UL-DL-ConfigCommon.

[0061] As can be seen above, the above solution does not clearly specify the specific time domain position of the SBFD time domain resources within the period of the TDD frame structure, so the above solution cannot be directly applied to the FD communication system. In addition, the specific configuration method for SBFD time domain resource configuration and the solution to time domain resource conflicts are not clearly defined. To this end, an embodiment of the present application provides a time domain resource configuration method.

[0062] In one embodiment of the present application, see Figure 2, which is a flow chart of a time domain resource configuration method provided in one embodiment of the present application. The UEs in the cell are uniformly configured through the following step A to implement cell-level semi-static SBFD time domain resource configuration.

[0063] Step A: The base station sends a first RRC signaling to the UE.

[0064] Among them, the TDD-UL-DL-ConfigCommon in the above-mentioned first RRC signaling includes: TDD frame structure pattern and SBFD pattern. The above-mentioned TDD frame structure pattern is used to configure the TDD frame structure, and the above-mentioned SBFD pattern is used to configure the SBFD time domain resources, and carries the first parameter and the second parameter. The above-mentioned first parameter represents the period of the SBFD time domain resources, and the above-mentioned second parameter represents the time domain position of the SBFD time domain resources in the above-mentioned TDD frame structure or TDD frame structure pattern.

[0065] In an embodiment of the present application, the SBFD pattern is a structure, and the first parameter and / or the second parameter may be included in the SBFD pattern. In addition, the first parameter and the second parameter may also be configured in a dispersed manner in TDD-UL-DL-ConfigCommon. At this time, TDD-UL-DL-ConfigCommon may not actually include the SBFD pattern, and it can be considered that the SBFD pattern is not explicitly configured in TDD-UL-DL-ConfigCommon. The relationship between the first parameter and the second parameter and the SBFD pattern can be seen in detail below and will not be described in detail here.

[0066] In addition, the number of SBFD patterns cannot exceed the number of TDD frame structure patterns included in TDD-UL-DL-ConfigCommon. Since the current protocol stipulates that the maximum number of TDD frame structure patterns is 2, the maximum number of SBFD patterns is also 2.

[0067] In the solution provided in the embodiment of the present application, the base station sends a first cell-level RRC signaling to the UE, and the first RRC signaling includes a first parameter and a second parameter of the SBFD. Since the first parameter can represent the period of the SBFD time domain resource and the second parameter can represent the time domain position of the SBFD time domain resource in the TDD frame structure, the UE can configure the SBFD time domain resource based on the above-mentioned first parameter and second parameters after receiving the first RRC signaling, thereby realizing SBFD communication between the base station and the UE.

[0068] There are three cases for the correspondence between SBFD patterns and TDD frame structures:

[0069] One SBFD pattern corresponds to one TDD frame structure pattern, one SBFD pattern corresponds to two TDD frame structure patterns, and two SBFD patterns correspond to two TDD frame structure patterns respectively.

[0070] Therefore, there are two solutions for configuring SBFD patterns:

[0071] The first solution: SBFD patterns correspond one-to-one to TDD frame structure patterns, including one SBFD pattern corresponding to one TDD frame structure pattern, and two SBFD patterns corresponding to two TDD frame structure patterns respectively.

[0072] The second solution: one SBFD pattern corresponds to two TDD frame structure patterns.

[0073] The following first describes the first parameter included in TDD-UL-DL-ConfigCommon. The period of the SBFD time domain resources indicated by the first parameter should be an integer multiple of the period of the TDD frame structure. If it is configured as a non-integer multiple, the period of the SBFD time domain resources will not match the period of the TDD frame structure. This will cause SBFD symbols to be unusable, thereby reducing the overall performance of the SBFD system.

[0074] For example, when the TDD frame structure period is set to 2.5ms, the SBFD time domain resource period can be set to 2.5ms, 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms, but cannot be set to other values. When the TDD frame structure period is set to 1ms, the SBFD time domain resource period can be set to 2ms, 4ms, 5ms, 8ms, 10ms, 16ms, 20ms, 32ms, 40ms, 64ms, 80ms, 128ms, or 160ms.

[0075] There are two solutions for configuring the first parameter, that is, the period of the SBFD time domain resources.

[0076] Solution a: Directly specify the cycle length of the SBFD time domain resources.

[0077] In solution a, the SBFD time domain resource period is configured by setting the first parameter to a preset period duration. In this case, the first parameter is optional and is configured only when SBFD time domain resources are required. Preset period durations can be 0.5ms, 0.625ms, 1ms, 1.25ms, 2ms, 2.5ms, 4ms, 5ms, 8ms, 10ms, 16ms, 20ms, 32ms, 40ms, 64ms, 80ms, 128ms, or 160ms. If the preset period duration is further increased, the preset period duration becomes an integer multiple of 128ms and 160ms.

[0078] For example, for μ ref =0, 1, 2, 3, 5, 6, subcarrier spacing In the scenario of SBFD, the period length can be 4ms, 8ms, 16ms, 32ms, 40ms, 64ms, 80ms, 128ms, 160ms, etc. In this case, the configured first parameter sbfdPeriodicity (SBFD period) can be illustrated as:

[0079] sbfdPeriodicity ENUMERATED{ms0p5,ms0p625,ms1,ms1p25,ms2,ms2p5,ms4,ms5,ms8,ms10,ms16,ms20,ms32,ms40,ms64,ms80,ms128,ms160,...} optional.

[0080] Solution b: Specify the relationship between the period of the SBFD time domain resources and the period of the TDD frame structure.

[0081] In solution b, the first parameter indicates the multiple of the SBFD time domain resource period and the TDD frame structure period. In this case, the first parameter is optional. If not configured, the SBFD time domain resource period is assumed to be the same as the TDD frame structure period. If configured, it indicates the multiple of the SBFD time domain resource period and the TDD frame structure period.

[0082] For example, in this case, the first parameter can be expressed as sbfdPeriodicityFactor (SBFD periodicity factor). Its value can be 2, 3, 4, 5, 6, 7, 8, etc., or 2, 4, 5, 8, 10, 16, 20, etc. This application does not limit the specific value.

[0083] For solution a and solution b, there are different ways to configure the first parameter, which are described in detail below using different embodiments.

[0084] The first parameter is in the form of: the value of the cycle duration or a specific value of a multiple of the cycle duration and the TDD frame structure duration.

[0085] In one embodiment of the present application, the TDD-UL-DL-ConfigCommon includes a corresponding TDD frame structure pattern and an SBFD pattern, and the period duration represented by the first parameter is: the first integer multiple of the period configured by the TDD frame structure pattern.

[0086] The first parameter is in the form of: the value of the cycle duration or the specific value of the first integer multiple.

[0087] In the case where the first parameter is in the form of a periodic value, the first parameter is sbfdPeriodicity, which is expressed in P sbfd Indicates that the value is an integer multiple of the period of the TDD frame structure configured by the TDD frame structure pattern. If the period of the TDD frame structure is recorded as P, the first parameter can be expressed as P sbfd =aP, where a is the specific value of the first integer multiple.

[0088] In one embodiment of the present application, the TDD-UL-DL-ConfigCommon includes an SBFD pattern, the SBFD pattern corresponds to a TDD frame structure pattern, and the first parameter is included in the SBFD pattern.

[0089] When the first parameter is in the form of a cycle duration value and the first parameter is included in the SBFD pattern, an example of TDD-UL-DL-ConfigCommon in the first RRC signaling is:

[0090] When the first parameter is in the form of a specific value of the first integer multiple and the first parameter is included in the SBFD pattern, an example of the SBFD pattern in the first RRC signaling is:

[0091] TDD-UL-DL-Pattern-SBFD::=SEQUENCE{

[0092] sbfdPeriodicityFactor ENUMERATED{2, 4, 5, 8, 10, 16, 20,...}optional,

[0093] }

[0094] Here, sbfdPeriodicityFactor is a specific value of the first integer multiple.

[0095] In addition, the SBFD pattern may not be explicitly configured in TDD-UL-DL-ConfigCommon, and the first parameter may be directly included in TDD-UL-DL-ConfigCommon.

[0096] Specifically, when the first parameter is in the form of a cycle duration value and the first parameter is directly included in TDD-UL-DL-ConfigCommon, an example of TDD-UL-DL-ConfigCommon in the first RRC signaling is:

[0097] When the first parameter is in the form of a specific value of the first integer multiple and the first parameter is directly included in TDD-UL-DL-ConfigCommon, an example of the SBFD pattern in the first RRC signaling is:

[0098] Referring to FIG3 , which is a schematic diagram of a first type of SBFD time domain resources provided in an embodiment of the present application.

[0099] The diagram includes 20 slots (time slots), Slot0-Slot19, with slot types D, S, and U. Every five time slots in the diagram represent a TDD frame structure. For example, Slot0-Slot4 represents the first TDD frame structure, Slot5-Slot9 represents the second TDD frame structure, and so on. In this embodiment, there is only one TDD frame structure, which can be represented as DDDSU. That is, the time slots in the TDD frame structure are D slot, D slot, D slot, S slot, and U slot, in order. The SCS is 30 kHz, and the TDD frame structure period is 2.5 ms.

[0100] The SBFD in the figure represents SBFD time domain resources, which are allocated in the middle three time slots in the TDD frame structure. The duration of the SBFD time domain resource period represented by the first parameter is twice the period of the TDD frame structure, which is 5ms.

[0101] In another embodiment of the present application, the TDD-UL-DL-ConfigCommon includes two TDD frame structure patterns and two SBFD patterns in one-to-one correspondence. The period duration represented by the first parameter is the second integer multiple of the sum of the periods configured by the two TDD frame structure patterns.

[0102] The first parameter is in the form of: the value of the cycle duration or the specific value of the second integer multiple.

[0103] Specifically, when TDD-UL-DL-ConfigCommon includes two TDD frame structure patterns and two SBFD patterns in one-to-one correspondence, the first parameter is configured inside the SBFD pattern. The value of the cycle length represented by the first parameter is P sbfd +P sbfd2 .P sbfd is the second integer multiple of the period of a TDD frame structure, P sbfd2 It is the second integer multiple of the period of another TDD frame structure.

[0104] At this time, when the first parameter is in the form of a cycle duration value, an example of TDD-UL-DL-ConfigCommon in the first RRC signaling is:

[0105] In the case where the first parameter is in the form of a specific value of the second integer multiple, an example of TDD-UL-DL-ConfigCommon in the first RRC signaling is:

[0106] Referring to FIG4 , which is a schematic diagram of a second type of SBFD time domain resources provided in an embodiment of the present application.

[0107] The diagram includes 40 slots (time slots), Slot0-Slot39, with slot types D, S, and U. Every five time slots in the diagram represent a TDD frame structure pattern. For example, Slot0-Slot4 represents the first TDD frame structure pattern, Slot5-Slot9 represents the second TDD frame structure pattern, and Slot0-Slot9 together constitute a TDD frame structure, and so on. This embodiment includes two TDD frame structure patterns. The TDD frame structure patterns can be represented as DDSUU and DDDSU, respectively. The time slots in the first TDD frame structure pattern are D slot, D slot, S slot, U slot, and U slot, in order. The time slots in the second TDD frame structure pattern are D slot, D slot, D slot, S slot, and U slot, in order. The SCS is 30 kHz. The period of the TDD frame structure is 5 ms.

[0108] The SBFD time domain resource in the figure represents SBFD time domain resources. There are two SBFD patterns, each corresponding to two TDD frame structure patterns. Each SBFD pattern is configured with two SBFD time domain resources. The two SBFD time domain resources are located in two TDD frame structure patterns. The first SBFD time domain resource is configured in the middle three time slots of the first TDD frame structure pattern. The second SBFD time domain resource is configured in the first three time slots of the second TDD frame structure pattern. The SBFD time domain resource period is twice the TDD frame period, or 10ms. This means that two SBFD time domain resources exist every two TDD frame structures.

[0109] In another embodiment of the present application, the above-mentioned TDD-UL-DL-ConfigCommon includes an SBFD pattern and two TDD frame structure patterns, the above-mentioned SBFD pattern corresponds to the above-mentioned two TDD frame structure patterns, the above-mentioned SBFD pattern is used to configure the above-mentioned SBFD time domain resources, and the period length represented by the above-mentioned first parameter is: the third integer multiple of the sum of the periods configured by the above-mentioned two TDD frame structure patterns.

[0110] In one embodiment of the present application, the first parameter is in the form of: the value of the cycle duration or the specific value of the third integer multiple.

[0111] In one embodiment of the present application, the first parameter is included in the SBFD pattern;

[0112] or

[0113] The first parameter is included in the TDD-UL-DL-ConfigCommon.

[0114] In the case where the first parameter is the preset third period duration, the first parameter is sbfdPeriodicity, with P sbfd Indicates that the value is an integer multiple of the sum of the periods of the two TDD frame structures configured by the two TDD frame structure patterns. If the periods of the two TDD frame structures are denoted as P and P2 respectively, the period of the SBFD time domain resource can be expressed as P sbfd =b(P+P2) wherein b is a specific value of the third integer multiple.

[0115] When the value of the first parameter is the value of the cycle duration and the first parameter is included in the SBFD pattern, an example of TDD-UL-DL-ConfigCommon in the first RRC signaling is:

[0116] When the value of the first parameter is a specific value of the third integer multiple and the first parameter is included in the SBFD pattern, sbfdPeriodicityFactor is a specific value of the third integer multiple. The SBFD pattern in the first RRC signaling can be expressed as:

[0117] TDD-UL-DL-Pattern-SBFD::=SEQUENCE{

[0118] sbfdPeriodicityFactor ENUMERATED{2, 4, 5, 8, 10, 16, 20,...}optional,

[0119] }

[0120] In addition, the SBFD pattern may not be explicitly configured in TDD-UL-DL-ConfigCommon, and the first parameter may be directly included in TDD-UL-DL-ConfigCommon.

[0121] Specifically, when the value of the first parameter is the value of the cycle duration and the first parameter is directly included in TDD-UL-DL-ConfigCommon, an example of TDD-UL-DL-ConfigCommon in the first RRC signaling is:

[0122] When the value of the first parameter is a specific value of the third integer multiple and the first parameter is directly included in TDD-UL-DL-ConfigCommon, bfdPeriodicityFactor is a specific value of the third integer multiple. An example of the SBFD pattern in the first RRC signaling is:

[0123] In another embodiment of the present application, the second parameter indicates the time domain position of one or two SBFD time domain resources in a TDD frame structure or a TTD frame structure pattern.

[0124] Specifically, when the SBFD pattern included in TDD-UL-DL-ConfigCommon corresponds one-to-one with the TDD frame structure pattern, the SBFD time domain resources are located in the TDD frame structure pattern. When TDD-UL-DL-ConfigCommon contains one SBFD pattern corresponding to two TDD frame structure patterns, the SBFD time domain resources are located in the TDD frame structure.

[0125] If one set of second parameters exists, one or two SBFD time domain resources can be configured. If two sets of second parameters exist, each set of second parameters configures one or two SBFD time domain resources, and the two sets of second parameters can configure a total of 2-4 SBFD time domain resources.

[0126] In one embodiment of the present application, if the TDD-UL-DL-ConfigCommon includes an SBFD pattern and two TDD frame structure patterns, the SBFD time domain resource represented by the second parameter is within the range of the TDD frame structure configured by the two TDD frame structure patterns;

[0127] If the SBFD pattern included in the TDD-UL-DL-ConfigCommon corresponds one-to-one with the TDD frame structure pattern, the SBFD time domain resource represented by the second parameter is within the range of the TDD frame structure pattern.

[0128] If there is a set of second parameters and a TDD frame structure pattern, the SBFD time domain resources configured by the second parameters are located within the TDD frame structure configured by the TDD frame structure pattern. If the length of the SBFD time domain resources exceeds the range of the TDD frame structure, the excess portion is invalid.

[0129] If there are two sets of second parameters and two TDD frame structure patterns, the SBFD time domain resources configured by each set of second parameters are located in the TDD frame structure pattern corresponding to the SBFD pattern to which the second parameters belong. If the length of the SBFD time domain resources exceeds the range of the TDD frame structure pattern, the excess portion is invalid.

[0130] If there is a set of second parameters and two TDD frame structure patterns, the SBFD time domain resources configured by the second parameters can span the TDD frame structure patterns and be located anywhere in the TDD frame structure configured by the two TDD frame structure patterns. However, if the SBFD time domain resources exceed the range of the TDD frame structure, the excess portion is invalid.

[0131] Furthermore, if only one set of second parameters exists in TDD-UL-DL-ConfigCommon, the second parameters may be included in an SBFD pattern within TDD-UL-DL-ConfigCommon. The second parameters may also not be included in the SBFD pattern. In this case, the SBFD pattern may not be explicitly configured in TDD-UL-DL-ConfigCommon.

[0132] If there are two sets of second parameters in TDD-UL-DL-ConfigCommon, the second parameters are respectively included in two SBFD patterns in TDD-UL-DL-ConfigCommon.

[0133] In one embodiment of the present application, the above-mentioned second parameter includes: a third parameter and a fourth parameter; when the above-mentioned TDD frame structure pattern corresponds one-to-one to the above-mentioned SBFD pattern, the above-mentioned third parameter indicates: the position of the starting symbol of the above-mentioned SBFD time domain resource in the above-mentioned TDD frame structure pattern; when one SBFD pattern corresponds to two TDD frame structure patterns, the above-mentioned third parameter indicates: the position of the starting symbol of the above-mentioned SBFD time domain resource in the TDD frame structure; the above-mentioned fourth parameter is the symbol length of the above-mentioned SBFD time domain resource.

[0134] Or, the above-mentioned second parameter includes: the above-mentioned third parameter and the fifth parameter; when the above-mentioned TDD frame structure pattern corresponds one-to-one to the above-mentioned SBFD pattern, the above-mentioned fifth parameter indicates: the position of the termination symbol of the above-mentioned SBFD time domain resource in the above-mentioned TDD frame structure pattern; when one SBFD pattern corresponds to two TDD frame structure patterns, the above-mentioned fifth parameter indicates: the position of the termination symbol of the above-mentioned SBFD time domain resource in the TDD frame structure.

[0135] If the second parameter includes the third parameter and the fourth parameter, it means that symbols of a length of consecutive symbols of the fourth parameter starting from the position indicated by the third parameter all belong to the SBFD time domain resources.

[0136] If the second parameter includes the third parameter and the fifth parameter, it means that all symbols from the position indicated by the third parameter to the position indicated by the fifth parameter belong to the SBFD time domain resources.

[0137] In addition, no matter whether the first parameter includes the third parameter and the fourth parameter, or the third parameter and the fifth parameter, a pair of parameters must exist in pairs.

[0138] In one embodiment of the present application, the third parameter is the order of the start symbol from front to back or from back to front in the TDD frame structure pattern or the symbols of the TDD frame structure. When the third parameter indicates a front-to-back order, the start symbol is the leading symbol from front to back. When the third parameter indicates a back-to-front order, the start symbol is the leading symbol from back to front.

[0139] On this basis, the second parameter represents the time domain position of an SBFD time domain resource in the TDD frame structure or TDD frame structure pattern, and the second parameter includes a third parameter of the SBFD time domain resource. In this case, the third parameter of the SBFD time domain resource is the order of the starting symbols of the SBFD time domain resource from front to back in the symbols of the TDD frame structure or TDD frame structure pattern.

[0140] Alternatively, the second parameter represents the time domain positions of the two SBFD time domain resources in the TDD frame structure or TDD frame structure pattern, and the second parameter includes two sets of parameters. The second parameter then includes third parameters for the first SBFD time domain resource and the second SBFD time domain resource. The first SBFD time domain resource is located before the second SBFD time domain resource. In this case, the third parameter of the first SBFD time domain resource is the order of the starting symbols of the first SBFD time domain resource from front to back within the symbols of the TDD frame structure or TDD frame structure pattern. The third parameter of the second SBFD time domain resource is the order of the starting symbols of the second SBFD time domain resource from back to front within the symbols of the TDD frame structure or TDD frame structure pattern.

[0141] Based on the above embodiment, if the second parameter is included in the SBFD pattern, the SBFD pattern corresponds one-to-one to the TDD frame structure pattern, and the second parameter represents the time domain position of the two SBFD time domain resources in the TDD frame structure pattern, then an example of the SBFD pattern in TDD-UL-DL-ConfigCommon is:

[0142] Among them, startSymbolOfSbfd1 (SBFD start symbol 1) is the third parameter of the first SBFD time domain resource. nrofSbfdSymbols1 (SBFD symbol number 1) is the fourth parameter of the first SBFD time domain resource. startSymbolOfSbfd2 (SBFD start symbol 2) is the third parameter of the second SBFD time domain resource. nrofSbfdSymbols2 (SBFD symbol number 2) is the fourth parameter of the second SBFD time domain resource.

[0143] Furthermore, in an embodiment of the present application, if the first SBFD time domain resource overlaps with the second SBFD time domain resource, the priority of the first SBFD time domain resource in the overlapping portion is higher than that of the second SBFD time domain resource.

[0144] That is, if there is an overlap between the configuration of the second parameter for the first SBFD time domain resource and the configuration of the second SBFD time domain resource, the overlap belongs to the first SBFD time domain resource.

[0145] In another embodiment of the present application, symbols in the first SBFD time domain resource that overlap with traditional UL symbols are invalid.

[0146] That is, the configuration of the first SBFD time domain resource may only be applied to other symbols except the traditional UL symbols in the TDD frame structure.

[0147] In addition, for symbols other than legacy UL symbols, whether the configuration of the first SBFD time-domain resource is effective can be controlled by the sixth parameter included in the above-mentioned TDD-UL-DL-ConfigCommon. When the sixth parameter is included in the above-mentioned TDD-UL-DL-ConfigCommon, the sixth parameter indicates whether the first symbol in the above-mentioned first SBFD time-domain resource that coincides with a legacy DL symbol or a legacy F symbol is invalid. And / or, when the sixth parameter is not included in the above-mentioned TDD-UL-DL-ConfigCommon, the first symbol that coincides with the above-mentioned legacy DL symbol or the above-mentioned legacy F symbol is valid.

[0148] The sixth parameter may be referred to as a first SBFD symbol configuration indication parameter (sbfdIndicator1), and the sixth parameter is an optional parameter.

[0149] The above-mentioned traditional UL symbol is: the UL symbol included in the above-mentioned TDD frame structure, the above-mentioned traditional DL symbol is: the DL symbol included in the above-mentioned TDD frame structure, and the above-mentioned traditional F symbol is: the F symbol included in the above-mentioned TDD frame structure.

[0150] In addition, if the sixth parameter exists, when the sixth parameter takes the first value, the first symbol that coincides with the traditional DL symbol is valid, and the first symbol that coincides with the traditional F symbol is invalid.

[0151] When the sixth parameter takes the second value, the first symbol that overlaps with the traditional DL symbol is invalid, and the first symbol that overlaps with the traditional F symbol is valid.

[0152] For example, the first value may be 0, and the second value may be 1. Of course, the first value and the second value may also be other values, and the embodiment of the present application does not limit the specific values.

[0153] The above sbfdIndicator1 can be defined as: sbfdIndicator1 ENUMERATED {0, 1} optional.

[0154] Similarly, in another embodiment of the present application, symbols in the second SBFD time-domain resource that overlap with conventional DL symbols are invalid.

[0155] That is, the configuration of the second SBFD time-domain resources may only be applied to symbols other than the legacy DL symbols in the TDD frame structure.

[0156] In addition, for symbols other than legacy DL symbols, whether the configuration of the second SBFD time-domain resource is effective can be controlled by the seventh parameter included in the above-mentioned TDD-UL-DL-ConfigCommon. When the seventh parameter is included in the above-mentioned TDD-UL-DL-ConfigCommon, the above-mentioned seventh parameter indicates whether the second symbol in the above-mentioned second SBFD time-domain resource that coincides with the legacy UL symbol or the legacy F symbol is invalid. And / or, when the seventh parameter is not included in the above-mentioned TDD-UL-DL-ConfigCommon, the second symbol that coincides with the above-mentioned legacy UL symbol or the above-mentioned legacy F symbol is valid.

[0157] The seventh parameter may be referred to as a second SBFD symbol configuration indication parameter (sbfdIndicator2), and the seventh parameter is an optional parameter.

[0158] In one embodiment of the present application, when the seventh parameter is set to the third value, the second symbol that coincides with the traditional UL symbol is valid, and the second symbol that coincides with the traditional F symbol is invalid;

[0159] When the seventh parameter takes the fourth value, the second symbol that overlaps with the traditional UL symbol is invalid, and the second symbol that overlaps with the traditional F symbol is valid.

[0160] For example, the third value may be 0, and the fourth value may be 1. Of course, the third value and the fourth value may also be other values, and this application does not limit the specific values.

[0161] The above sbfdIndicator2 can be defined as: sbfdIndicator2 ENUMERATED {0, 1} optional.

[0162] It should be noted that if the first SBFD time domain resource and the second SBFD time domain resource overlap, then in the overlapping portion, the sixth parameter for the first SBFD time domain resource has a higher priority than the seventh parameter for the second SBFD time domain resource.

[0163] If the second parameter is included in the SBFD pattern, the SBFD pattern corresponds one-to-one with the TDD frame structure pattern, and the second parameter represents the time domain position of the two SBFD time domain resources in the TDD frame structure pattern. In the case where sbfdIndicator1 and sbfdIndicator2 exist, an example of the SBFD pattern in TDD-UL-DL-ConfigCommon is:

[0164] If TDD-UL-DL-ConfigCommon contains two TDD frame structure patterns and does not explicitly configure the SBFD pattern, and there are sbfdIndicator1 and sbfdIndicator2, an example of TDD-UL-DL-ConfigCommon is:

[0165] If TDD-UL-DL-ConfigCommon contains two TDD frame structure patterns and one SBFD pattern, the second parameter is included in the above SBFD pattern. In the case of sbfdIndicator1 and sbfdIndicator2, an example of TDD-UL-DL-ConfigCommon is:

[0166] The following describes the position of SBFD time domain resources in the TDD frame structure pattern using the specific examples shown in FIG5 and FIG6.

[0167] Referring to FIG5 , which is a schematic diagram of a third type of SBFD time domain resources provided in an embodiment of the present application.

[0168] The figure includes 10 time slots, from time slot 0 to time slot 9. Time slots 0 to time slot 4 are the first TDD frame structure pattern. This TDD frame structure pattern can be represented as DDSUU. The time slots in this TDD frame structure pattern are, in order, D slot, D slot, S slot, U slot, and U slot. D slots are configured as all DL symbols, so they are represented as DL in the figure. S slots are configured as all F symbols, so they are represented as F in the figure. U slots are configured as all UL symbols, so they are represented as UL in the figure. Slots 5 to 9 are the second TDD frame structure. This TDD frame structure pattern can be represented as DDDSU. The time slots in this TDD frame structure pattern are, in order, D slot, D slot, S slot, and U slot. D slots are configured as all DL symbols, so they are represented as DL in the figure. S slots are configured as all F symbols, so they are represented as F in the figure. U slots are configured as all UL symbols, so they are represented as UL in the figure. The TDD frame structure in Figure 4 has a period of 5 ms. Each of the two TDD frame structure patterns includes an SBFD time domain resource.

[0169] The third parameter of the first SBFD time-domain resource is: startSymbolOfSbfd1 = 21 (time slot 0 contains 14 symbols, and time slot 1 contains the first 7 symbols of the first SBFD time-domain resource), and the fourth parameter is: nrofSbfdSymbols1 = 28. Because sbfdIndicator1 is not configured, the first SBFD time-domain resource is valid in both legacy DL symbols and legacy F symbols, but not in legacy UL symbols (such as the first 7 symbols in time slot 3).

[0170] The third parameter of the second SBFD time-domain resource is: startSymbolOfSbfd2 = 0 (start symbol order from back to front), and the fourth parameter is: nrofSbfdSymbols2 = 35. sbfdIndicator2 = 0. This means that the second SBFD time-domain resource is valid only in legacy UL symbols, not in legacy DL symbols or legacy F symbols. For example, the last seven symbols in slot 7 are still legacy DL symbols, and all symbols in slot 8 are still legacy F symbols.

[0171] Referring to FIG6 , which is a schematic diagram of a fourth type of SBFD time-domain resource provided in an embodiment of the present application.

[0172] The figure includes 10 time slots, time slot 0 to time slot 9. The TDD frame structure pattern in Figure 6 is the same as the TDD frame structure pattern in Figure 4 and is not described again. The TDD frame structure shown in Figure 6 includes one SBFD time domain resource.

[0173] The third parameter of the SBFD time-domain resource is startSymbolOfSbfd1 = 21, and the fourth parameter is nrofSbfdSymbols1 = 63. Other parameters are not configured. This means that SBFD time-domain resources are effective in both legacy DL symbols and legacy F symbols, but not in legacy UL symbols. For example, all symbols in slots 3 and 4 remain legacy UL symbols.

[0174] As can be seen from the above, the embodiment of the present application configures a conflict handling mechanism when there is an overlapping conflict between the SBFD time domain resources and the traditional time slots in the TDD frame structure or TDD frame structure pattern, and the overlapping conflict can be further handled by configuring the optional sixth parameter and / or seventh parameter. For the two SBFD time domain resources configured with the second parameter, a variety of different conflict handling mechanisms are provided.

[0175] In another embodiment of the present application, the base station may further perform the following step B to implement user-level dynamic SBFD time-domain resource configuration for a specific UE.

[0176] Step B: Send a second RRC signaling to the above UE.

[0177] The TDD-UL-DL-ConfigDedicated in the second RRC signaling includes an eighth parameter, and the eighth parameter is used to configure symbols in some time slots in the TDD frame structure as SBFD symbols, and the SBFD symbols have SBFD subband resources.

[0178] It should be noted that although both TDD-UL-DL-ConfigDedicated and TDD-UL-DL-ConfigCommon are included in RRC signaling, they are used for user-level and cell-level configuration respectively. Therefore, they need to be included in different first and second RRC signaling, respectively, and sent to the UE.

[0179] In addition, it should be noted that, when the sixth parameter and / or the seventh parameter exist, the configuration of the time slot by the eighth parameter complies with the rules defined by the sixth parameter and / or the seventh parameter.

[0180] The eighth parameter is used to configure SBFD symbols within a time slot in units of time slots.

[0181] In one embodiment of the present application, the eighth parameter includes a ninth parameter, and the ninth parameter indicates that: all symbols in a specified DL time slot and / or S time slot in the TDD frame structure are configured as first SBFD symbols;

[0182] and / or

[0183] The eighth parameter includes a tenth parameter, which indicates that all symbols in a specified UL time slot and / or S time slot in the TDD frame structure are configured as second SBFD symbols;

[0184] and / or

[0185] The eighth parameter includes an eleventh parameter, which indicates that a specified portion of symbols in a DL time slot and / or an S time slot in a TDD frame structure is configured as the first SBFD symbol;

[0186] and / or

[0187] The eighth parameter includes a twelfth parameter, and the twelfth parameter indicates that a specified portion of symbols in the UL time slot and / or the S time slot in the TDD frame structure is configured as the second SBFD symbols.

[0188] In one case, the eighth parameter may configure all symbols in some time slots in the TDD frame structure as SBFD symbols.

[0189] In one embodiment of the present application, the eighth parameter includes a ninth parameter, and the ninth parameter indicates that all symbols in a DL time slot and / or an S time slot specified in the TDD frame structure are configured as first SBFD symbols.

[0190] For example, the ninth parameter mentioned above may be referred to as allSbfd1 (all SBFD1).

[0191] In another embodiment of the present application, the eighth parameter includes a tenth parameter, and the tenth parameter indicates that all UL symbols in a specified UL time slot and / or S time slot in the TDD frame structure are configured as second SBFD symbols.

[0192] For example, the tenth parameter mentioned above may be referred to as allSbfd2 (all SBFD2).

[0193] In another case, the eighth parameter may configure some symbols in some time slots in the TDD frame structure as SBFD symbols.

[0194] In one embodiment of the present application, the eighth parameter includes an eleventh parameter, and the eleventh parameter indicates that a specified portion of symbols in the DL time slot and / or S time slot in the TDD frame structure is configured as the first SBFD symbol.

[0195] Among them, the above-mentioned eleventh parameter may include: the position of the starting symbol in the above-mentioned specified partial symbols in the DL time slot and / or S time slot, the length of the above-mentioned specified partial symbols, and the above-mentioned eleventh parameter is invalid for the configuration of symbols beyond the said time slot.

[0196] Specifically, the position of the start symbol in the specified partial symbols in the UL time slot and / or S time slot can be expressed as: startSymbolOfSbfd1, and the length of the specified partial symbols is nrofSbfdSymbols1, indicating that starting from the startSymbolOfSbfd1 symbol in the time slot, consecutive nrofSbfdSymbols 1 symbols are configured as SBFD symbols.

[0197] Furthermore, it should be noted that when both the first SBFD symbol and the second SBFD symbol exist in a time slot, the portion of the first SBFD symbol that overlaps with the second SBFD symbol in the same time slot is configured as the first SBFD symbol. In other words, the portion of the first SBFD symbol that overlaps with the second SBFD symbol belongs to the first SBFD symbol.

[0198] In addition, the above-mentioned eleventh parameter may also include: the position of the start symbol in the above-mentioned specified partial symbols in the UL time slot and / or S time slot, and the position of the end symbol in the above-mentioned specified partial symbols in the time slot.

[0199] In another embodiment of the present application, the eighth parameter includes a twelfth parameter, and the twelfth parameter indicates that a specified portion of symbols in the UL time slot and / or S time slot in the TDD frame structure is configured as the second SBFD symbol.

[0200] Among them, the above-mentioned twelfth parameter may include: the position of the starting symbol in the above-mentioned specified partial symbols in the UL time slot and / or S time slot, the length of the above-mentioned specified partial symbols, and the above-mentioned twelfth parameter is invalid for the configuration of symbols beyond the said time slot.

[0201] Specifically, the position of the start symbol in the specified partial symbols in the UL time slot and / or S time slot can be expressed as: startSymbolOfSbfd2, and the length of the specified partial symbols is nrofSbfdSymbols2, indicating that starting from the startSymbolOfSbfd2th symbol in the time slot, consecutive nrofSbfdSymbols2 symbols are configured as SBFD symbols.

[0202] In addition, the twelfth parameter may also include: the position of the start symbol in the designated partial symbols in the UL time slot and / or S time slot, and the position of the end symbol in the designated partial symbols in the time slot.

[0203] Referring to FIG. 7 , it is a schematic diagram of a fifth type of SBFD time-domain resource provided in an embodiment of the present application.

[0204] Figure 7 includes time slots 1 to 2, for a total of 2 time slots. Each time slot contains symbols 0 to 13, for a total of 14 symbols. Figure 6 shows a schematic diagram of the result after using the second RRC signaling to configure user-level SBFD time domain resources. Among them, time slot 1 is a D time slot, time slot 2 is an S time slot, and all symbols in the S time slot are F symbols. For time slot 1, allSbfd1 is configured to configure all symbols in time slot 1 as SBFD time domain resources. The remaining parameters are not configured. In time slot 2, startSymbolOfSbfd1 is configured to 1, nrofSbfdSymbols1 is configured to 12, then the first 12 symbols in time slot 2 are configured as SBFD time domain resources.

[0205] As can be seen from the above, in the solution provided by the embodiment of the present application, the base station can further configure the SBFD symbols of the UE through the eighth parameter in the TDD-UL-DL-ConfigDedicated contained in the second RRC signaling. This enables dynamic configuration of the user level of a specific UE and flexible configuration of the SBFD time domain resources of the UE.

[0206] In some scenarios, it is necessary to cancel the configuration of SBFD time domain resources, that is, to restore the configured SBFD time domain resources to traditional time slots in the TDD frame structure. In this case, the restoration process can be implemented through the following embodiments.

[0207] In one embodiment of the present application, the base station may further perform the following step C.

[0208] Step C: Send a third RRC signaling to the UE.

[0209] The third RRC signaling includes a thirteenth parameter, and the thirteenth parameter is used to control the UE to restore the configuration of time domain resources to the state before receiving the second RRC signaling.

[0210] The thirteenth parameter may be referred to as revertToOriginal. When the UE receives the third RRC signaling including the thirteenth parameter, the configuration of the SBFD time domain resources is restored to the configuration before the second RRC signaling is received.

[0211] The thirteenth parameter may be included in the TDD-UL-DL-ConfigDedicated field. The thirteenth parameter may be included in the TDD-UL-DL-ConfigDedicated field of the same RRC signaling as any one or more of the eighth to twelfth parameters. In this case, the second RRC signaling and the third RRC signaling are the same RRC signaling.

[0212] Alternatively, the thirteenth parameter is separately included in the TDD-UL-DL-ConfigDedicated of one RRC signaling. In this case, the second RRC signaling and the third RRC signaling are not the same RRC signaling.

[0213] In one embodiment of the present application, the above-mentioned eighth to thirteenth parameters can be configured in a structure parameter, the above-mentioned structure parameter can be named TDD-UL-DL-SlotConfig-SBFD (time division duplex-uplink-downlink-time slot configuration-subband full duplex), and TDD-UL-DL-SlotConfig-SBFD can be added to TDD-UL-DL-ConfigDedicated.

[0214] An example of TDD-UL-DL-ConfigDedicated is:

[0215] Alternatively, another example of TDD-UL-DL-ConfigDedicated is:

[0216] Here, slotSpecificConfigurationsToAddModList-SBFD (SBFD specific configuration time slot set) represents a set of time slots to be configured with SBFD symbols.

[0217] In another embodiment of the present application, in order to implement configuration recovery, the above-mentioned base station may also perform the following step D.

[0218] Step D: Send a fourth RRC signaling to the UE.

[0219] The fourth RRC signaling includes a fourteenth parameter, and the fourteenth parameter is used to control the UE to restore the configuration of the time domain resources to the state before the SBFD time domain resources are configured.

[0220] The fourteenth parameter may be expressed as slotSpecificConfigurationsToReleaseList (slot-specific configuration release list), which releases a series of time slots in the SBFD time domain resources and restores the TDD frame structure to its original state.

[0221] The fourteenth parameter may be included in the TDD-UL-DL-ConfigDedicated field. The fourteenth parameter may be included in the TDD-UL-DL-ConfigDedicated field of the same RRC signaling as any one or more of the eighth to twelfth parameters. In this case, the second RRC signaling and the fourth RRC signaling are the same RRC signaling.

[0222] Alternatively, the fourteenth parameter is separately included in the TDD-UL-DL-ConfigDedicated of one RRC signaling. In this case, the second RRC signaling and the fourth RRC signaling are not the same RRC signaling.

[0223] An example of TDD-UL-DL-ConfigDedicated is:

[0224] In summary, the embodiments of this application detail how to configure SBFD time-domain resources in a semi-static (cell-level) or dynamic (user-level) manner. Through these embodiments, SBFD time-frequency resources can be clearly and flexibly configured based on current TDD technology. This integration of SBFD time-frequency resource configuration with the current TDD frame structure facilitates the practical implementation of SBFD technology.

[0225] Corresponding to the aforementioned time domain resource configuration method applied to the base station, the present application also provides a time domain resource configuration method applied to the UE.

[0226] The embodiment of the present application provides a time domain resource configuration method, which is applied to a UE. Referring to Figure 8 , it is a flow chart of another time domain resource configuration method provided by an embodiment of the present application. The above method includes the following steps E to F.

[0227] Step E: Receive a first RRC signaling sent by the base station;

[0228] The time division duplex-uplink-downlink-common configuration TDD-UL-DL-ConfigCommon in the first RRC signaling includes: a TDD frame structure pattern and an SBFD pattern, the TDD frame structure pattern is used to configure the TDD frame structure, the SBFD pattern is used to configure the SBFD time domain resources, and carries a first parameter and a second parameter, the first parameter indicates the period of the SBFD time domain resources, and the second parameter indicates the time domain position of the SBFD time domain resources in the TDD frame structure or the TDD frame structure pattern;

[0229] Step F: According to the TDD frame structure pattern, SBFD pattern, first parameter and second parameter, configure the TDD frame structure and SBFD time domain resources.

[0230] As can be seen from the above, in the solution provided in the embodiment of the present application, the base station sends a first cell-level RRC signaling to the UE, and the first RRC signaling includes a first parameter and a second parameter of the SBFD. Since the first parameter can represent the period of the SBFD time domain resource and the second parameter can represent the time domain position of the SBFD time domain resource in the TDD frame structure, the UE can configure the SBFD time domain resource based on the above-mentioned first parameter and second parameters after receiving the first RRC signaling, thereby realizing SBFD communication between the base station and the UE.

[0231] In one embodiment of the present application, the TDD-UL-DL-ConfigCommon includes a corresponding TDD frame structure pattern and an SBFD pattern, and the period duration represented by the first parameter is: a first integer multiple of the period configured by the TDD frame structure pattern;

[0232] or

[0233] The TDD-UL-DL-ConfigCommon includes two TDD frame structure patterns and two SBFD patterns in one-to-one correspondence, and the period duration represented by the first parameter is: the second integer multiple of the sum of the periods configured by the two TDD frame structure patterns;

[0234] or

[0235] The TDD-UL-DL-ConfigCommon includes an SBFD pattern and two TDD frame structure patterns, the SBFD pattern corresponds to the two TDD frame structure patterns, the SBFD pattern is used to configure the SBFD time domain resources, and the period duration represented by the first parameter is: the third integer multiple of the sum of the periods configured by the two TDD frame structure patterns.

[0236] In one embodiment of the present application, the first parameter is in the form of: the value of the cycle duration or a specific value of a multiple of the cycle duration and the TDD frame structure duration.
