[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0049] To achieve integrated communication and sensing functions in a base station, the base station needs to send messages for communication and simultaneously receive sensing messages for sensing. Therefore, the base station needs to be able to send and receive messages simultaneously, meaning it needs FD (Full-Duplex) communication capabilities. However, FD communication introduces additional factors affecting communication quality, such as self-interference (SI), inter-cell crosstalk, and inter-user interference. SI is the most serious among these. To suppress SI, related technologies combine passive RF (Radio Frequency) SI suppression, active analog SI cancellation, and active digital SI cancellation to ensure full-duplex communication performance. However, from a practical application perspective, these SI suppression techniques correspondingly increase the complexity of the base station and user terminals. Therefore, it is necessary to implement FD while suppressing SI and reducing the complexity of the base station and user terminals. In this case, SBFD (Single-Segmented FD) is a feasible solution.
[0050] First, the configuration of SBFD time-domain resources in current related technologies is explained. In 5G (5th Generation Mobile Communication Technology) systems, the TDD (Time Division Duplex) frame structure is divided into UL (Ultra-Low) time slots, DL (Low-Low) time slots, and S (Slots) time slots, based on time slot units. The symbols in the S time slot 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.
[0051] The base station can inform the UE of the configured TDD frame structure via RRC (Radio Resource Control) signaling in a semi-static configuration mode. The RRC signaling can contain either TDD-UL-DL-ConfigCommon (Time Division Duplex-UpLink-DownLink-ConfigurationCommon, a general configuration for time division duplex uplink downlink) or TDD-UL-DL-ConfigDedicated (Time Division Duplex-UpLink-DownLink-ConfigurationDedicated, a dedicated configuration for time division duplex uplink downlink). The former configures the cell-level TDD frame structure, while the latter configures a UE-specific TDD frame structure. A maximum of two TDD frame structure patterns can be configured in TDD-UL-DL-ConfigCommon. 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, UL symbol, or F symbol. If a TDD frame structure pattern exists, that TDD frame structure is directly configured. If two TDD frame structure patterns exist, the two TDD frame structure patterns can be used together to configure the overall frame structure of TDD.
[0052] The period of a TDD frame structure is configured using the dl-UL-TransmissionPeriodicity (DownLink-UpLink-TransmissionPeriodicity) parameter in the TDD frame structure pattern. If a TDD frame structure pattern exists, the TDD frame structure period is the period configured in that pattern, which can be denoted as P1. If two TDD frame structure patterns exist, the TDD frame structure period is the sum of the periods configured in both patterns, which can be denoted as P1+P2. P1 and P2 are the periods configured in the two TDD frame structure patterns, respectively.
[0053] Figure 1 This is a schematic diagram of a frame structure provided as an embodiment of the related technology.
[0054] The diagram includes five time slots (0-4), each containing 14 symbols (0-13). In the diagram, DL symbols represent DL symbols used for transmitting downlink data, and UL symbols represent UL symbols used for transmitting uplink data. Time slot 3 is the S time slot. Symbols 0-9 in the S time slot are configured as DL symbols, symbols 12-13 as UL symbols, and symbols 10-11 as F symbols, serving as GP symbols for uplink / downlink handover. The uplink / downlink ratio in the diagram is approximately 1:4.
[0055] Furthermore, the base station can further modify the F symbol configured in TDD-UL-DL-ConfigCommon through the parameters included in TDD-UL-DL-ConfigDedicated, and can further configure it as a DL symbol or a UL symbol.
[0056] Based on this, in the current 3GPP (3rd Generation Partnership Project) standardization process, the following conclusions can be drawn regarding the time-domain resource allocation of SBFD:
[0057] For UEs in RRC connection mode, SBFD time-domain resources are configured within one 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:
[0058] Option 1: The period of the SBFD time domain resource is the same as the period of the TDD frame structure configured in TDD-UL-DL-ConfigCommon via dl-UL-TransmissionPeriodicity.
[0059] Option 2: The period of the SBFD time domain resource is an integer multiple of 1 greater than the period of the TDD frame structure configured in TDD-UL-DL-ConfigCommon via dl-UL-TransmissionPeriodicity.
[0060] As can be seen above, the above schemes do not explicitly specify the specific time-domain location of SBFD time-domain resources within the TDD frame structure period, therefore, the above schemes cannot be directly applied to FD communication systems. Furthermore, the specific configuration method for SBFD time-domain resources and the resolution method for time-domain resource conflicts are not clearly defined. Therefore, this application provides a time-domain resource configuration method.
[0061] In one embodiment of this application, see Figure 2This is a flowchart illustrating a time-domain resource configuration method provided in an embodiment of this application. The method involves uniformly configuring the UEs in the cell through the following step A to achieve semi-static SBFD time-domain resource configuration at the cell level.
[0062] Step A: The base station sends the first RRC signaling to the UE.
[0063] The 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, and the SBFD pattern is used to configure the SBFD time domain resources. It also 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.
[0064] In the embodiments of this application, the SBFD pattern is a structure, and the first parameter and / or the second parameter may be included in the SBFD pattern. Alternatively, the first and second parameters may also be configured separately in TDD-UL-DL-ConfigCommon. In this case, TDD-UL-DL-ConfigCommon may not actually contain the SBFD pattern; it can be considered that the SBFD pattern is not explicitly configured in TDD-UL-DL-ConfigCommon. The relationship between the first and second parameters and the SBFD pattern will be detailed below and will not be elaborated here.
[0065] Furthermore, the number of SBFD patterns cannot exceed the number of TDD frame structure patterns contained in TDD-UL-DL-ConfigCommon. Since the current protocol specifies a maximum of 2 TDD frame structure patterns, the maximum number of SBFD patterns is also 2.
[0066] In the scheme provided by the embodiments of this application, the base station sends a cell-level first RRC signaling to the UE. The first RRC signaling includes a first parameter and a second parameter of 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, after the UE receives the first RRC signaling, it can configure the SBFD time domain resource based on the above-mentioned first parameter and second parameter, thereby realizing SBFD communication between the base station and the UE.
[0067] Regarding the correspondence between SBFD patterns and TDD frame structures, there are three possibilities:
[0068] One SBFD pattern corresponds to one TDD frame structure pattern, one SBFD pattern corresponds to two TDD frame structure patterns, and two SBFD patterns each correspond to two TDD frame structure patterns.
[0069] Therefore, there are two configuration options for SBFD patterns:
[0070] Scheme 1: One-to-one correspondence between SBFD patterns and TDD frame structure patterns. This includes one SBFD pattern corresponding to one TDD frame structure pattern, and two SBFD patterns each corresponding to two TDD frame structure patterns.
[0071] The second option is to have one SBFD pattern correspond to two TDD frame structure patterns.
[0072] The first parameter included in TDD-UL-DL-ConfigCommon will be explained below. This first parameter indicates that the period of the SBFD time-domain resource should be an integer multiple of the period of the TDD frame structure. If configured as a non-integer multiple, it will cause a mismatch between the period of the SBFD time-domain resource and the period of the TDD frame structure. This will render SBFD symbols unusable, thereby reducing the overall performance of the SBFD system.
[0073] For example, when the TDD frame structure period is configured to 2.5ms, the SBFD time domain resource period can be configured to values such as 2.5ms, 5ms, 10ms, 20ms, 40ms, 80ms, and 160ms, but cannot be configured to other values. When the TDD frame structure period is configured to 1ms, the SBFD time domain resource period can be configured to values such as 2ms, 4ms, 5ms, 8ms, 10ms, 16ms, 20ms, 32ms, 40ms, 64ms, 80ms, 128ms, and 160ms.
[0074] There are two schemes for configuring the first parameter, which is the period of the SBFD time domain resource.
[0075] Option a: Directly specify the period duration of the SBFD time domain resources.
[0076] In scheme a, the period of the SBFD time-domain resource 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 the SBFD time-domain resource needs to be configured. The preset period duration can be 0.5ms, 0.625ms, 1ms, 1.25ms, 2ms, 2.5ms, 4ms, 5ms, 8ms, 10ms, 16ms, 20ms, 32ms, 40ms, 64ms, 80ms, 128ms, 160ms, etc. If the preset period duration continues to increase, the preset period duration will be an integer multiple of 128ms and 160ms.
[0077] For example, applicable to μ ref =0, 1, 2, 3, 5, 6, Subcarrier spacing In this scenario, the period duration can be 4ms, 8ms, 16ms, 32ms, 40ms, 64ms, 80ms, 128ms, 160ms, etc. In this case, the first parameter configured, sbfdPeriodicity (SBFD period), can be illustrated as follows:
[0078] sbfdPeriodicity ENUMERATED{ms0p5,ms0p625,ms1,ms1p25,ms2,ms2p5,ms4,ms5,ms8,ms10,ms16,ms20,ms32,ms40,ms64,ms80,ms128,ms160,...} optional.
[0079] Option b: Specify the relationship between the period of the SBFD time-domain resources and the period of the TDD frame structure.
[0080] In scheme b, the first parameter indicates the multiple relationship between the period of the SBFD time-domain resource and the period of the TDD frame structure. In this case, the first parameter is optional. If not configured, the period of the SBFD time-domain resource is the same as the period of the TDD frame structure by default. If configured, it indicates the multiple between the period of the SBFD time-domain resource and the period of the TDD frame structure.
[0081] For example, in this case, the first parameter can be represented as sbfdPeriodicityFactor (SBFD periodicity factor). Its values 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 values.
[0082] For scheme a and scheme b, there are different ways to configure the first parameter, which will be described in detail below with different implementation examples.
[0083] The first parameter mentioned above is in the form of: the value of the aforementioned period duration or the specific value of the multiple between the period duration and the TDD frame structure duration.
[0084] In one embodiment of this 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 in the TDD frame structure pattern.
[0085] The first parameter mentioned above is in the form of: the value of the aforementioned period duration or a specific value that is a first integer multiple of the aforementioned period duration.
[0086] When the first parameter is a value of the period duration, the first parameter is sbfdPeriodicity, with P sbfd This indicates that the value is an integer multiple of the period of the TDD frame structure configured in the TDD frame structure pattern. If the period of the TDD frame structure is denoted as P, then the first parameter can be expressed as P. sbfd = aP, where a is a specific value that is a first integer multiple of P.
[0087] In one embodiment of this application, the TDD-UL-DL-ConfigCommon includes an SBFD pattern, which corresponds to a TDD frame structure pattern, and the first parameter is included in the SBFD pattern.
[0088] When the first parameter is a value of period duration and is included within the SBFD pattern, an example of TDD-UL-DL-ConfigCommon in the first RRC signaling is as follows:
[0089]
[0090] When the first parameter is a specific value that is a multiple of the aforementioned first integer, and the first parameter is included in the SBFD pattern, an example of the SBFD pattern in the first RRC signaling is as follows:
[0091] TDD-UL-DL-Pattern-SBFD::=SEQUENCE{
[0092] sbfdPeriodicityFactor ENUMERATED{2, 4, 5, 8, 10, 16, 20,...}optional,
[0093] }
[0094] Wherein, sbfdPeriodicityFactor is the specific value of the first integer multiple.
[0095] In addition, SBFD patterns can be configured without explicit configuration in TDD-UL-DL-ConfigCommon, as the first parameter is directly included in TDD-UL-DL-ConfigCommon.
[0096] Specifically, when the first parameter is a value of the period duration and is directly included within TDD-UL-DL-ConfigCommon, an example of TDD-UL-DL-ConfigCommon in the first RRC signaling is as follows:
[0097]
[0098] When the first parameter is a specific value that is a multiple of the aforementioned first integer, and the first parameter is directly included in TDD-UL-DL-ConfigCommon, an example of the SBFD pattern in the first RRC signaling is as follows:
[0099]
[0100] See Figure 3 This is a schematic diagram of the first type of SBFD time-domain resource provided in an embodiment of this application.
[0101] The diagram contains 20 slots (Slots 0-19), with Slot Types including D, S, and U. Every five slots in the diagram constitute a TDD frame structure. For example, Slots 0-4 form the first TDD frame structure, Slots 5-9 form the second, and so on. This embodiment uses only one TDD frame structure, which can be represented as DDDSU, where the slots are sequentially slots D, D, D, S, and U. The SCS is 30kHz, and the period of the TDD frame structure is 2.5ms.
[0102] In the diagram, SBFD represents the SBFD time-domain resource, which is configured in the middle three time slots of the TDD frame structure. The duration of the SBFD time-domain resource, represented by the first parameter, is twice the period of the TDD frame structure, which is 5ms.
[0103] In another embodiment of this application, the aforementioned TDD-UL-DL-ConfigCommon includes two TDD frame structure patterns and two SBFD patterns that correspond one-to-one. The period duration represented by the aforementioned first parameter is a second integer multiple of the sum of the periods configured in the aforementioned two TDD frame structure patterns.
[0104] The first parameter is in the form of either the value of the period duration or a specific value that is a multiple of the second integer.
[0105] Specifically, when TDD-UL-DL-ConfigCommon contains two corresponding TDD frame structure patterns and two SBFD patterns, the first parameter is configured within the SBFD pattern. The value of the period duration represented by the first parameter is P. sbfd +P sbfd2 P sbfd P is the second integer multiple of the period of a TDD frame structure. sbfd2 It is the second integer multiple of the period of another TDD frame structure.
[0106] In this case, with the first parameter being a value in the form of a period duration, an example of TDD-UL-DL-ConfigCommon in the first RRC signaling would be:
[0107]
[0108]
[0109] When the first parameter is a specific value that is a multiple of the second integer, an example of TDD-UL-DL-ConfigCommon in the first RRC signaling is as follows:
[0110]
[0111] See Figure 4 This is a schematic diagram of a second type of SBFD time-domain resource provided in an embodiment of this application.
[0112] The diagram contains 40 slots (slots) from Slot0 to Slot39, with Slot Types including D, S, and U. Every five slots in the diagram constitute a TDD frame structure pattern. For example, Slots0-Slot4 form the first TDD frame structure pattern, Slots5-Slot9 form the second, and Slots0-Slot9 together form a TDD frame structure, and so on. This embodiment contains two types of TDD frame structure patterns. These patterns can be represented as DDSUU and DDDSU, respectively. In the first TDD frame structure pattern, the slots are sequentially slots D, D, S, U, and U. In the second TDD frame structure pattern, the slots are sequentially slots D, D, D, S, and U. The SCS is 30kHz. The period of the TDD frame structure is 5ms.
[0113] In the diagram, SBFD represents the SBFD time-domain resource. There are two SBFD patterns, each corresponding to a TDD frame structure pattern. Each SBFD pattern is configured with two SBFD time-domain resources. These two SBFD time-domain resources are located within the 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 period of the SBFD time-domain resource is twice the period of the TDD frame structure, which is 10ms. That is, there are two SBFD time-domain resources every two TDD frame structures.
[0114] In another embodiment of this application, the TDD-UL-DL-ConfigCommon contains 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. 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.
[0115] In one embodiment of this application, the first parameter is in the form of: the value of the period duration or a specific value that is a third integer multiple of the period duration.
[0116] In one embodiment of this application, the first parameter is included in the SBFD pattern.
[0117] or
[0118] The first parameter mentioned above is included in the TDD-UL-DL-ConfigCommon mentioned above.
[0119] When the first parameter is a preset third cycle duration, the first parameter is sbfdPeriodicity, with P sbfd This value indicates that it is an integer multiple of the sum of the periods of the two TDD frame structures configured in the two TDD frame structure patterns. If the periods of the two TDD frame structures are denoted as P and P2 respectively, then the period of the SBFD time-domain resource can be expressed as P. sbfd = b(P+P2). Where b is a specific value that is a multiple of the third integer.
[0120] When the first parameter is a value representing the period duration, and the first parameter is included within the SBFD pattern, an example of TDD-UL-DL-ConfigCommon in the first RRC signaling is as follows:
[0121]
[0122]
[0123] When the first parameter is a specific value that is a multiple of the aforementioned third integer, and the first parameter is included in the SBFD pattern, then sbfdPeriodicityFactor is a specific value that is a multiple of the third integer. The SBFD pattern in the first RRC signaling can be represented as:
[0124] TDD-UL-DL-Pattern-SBFD::=SEQUENCE{
[0125] sbfdPeriodicityFactor ENUMERATED{2, 4, 5, 8, 10, 16, 20,...}optional,
[0126] }
[0127] In addition, SBFD patterns can be configured without explicit configuration in TDD-UL-DL-ConfigCommon, as the first parameter is directly included in TDD-UL-DL-ConfigCommon.
[0128] Specifically, when the first parameter is a value representing the period duration, and the first parameter is directly included within TDD-UL-DL-ConfigCommon, an example of TDD-UL-DL-ConfigCommon in the first RRC signaling is as follows:
[0129]
[0130] When the first parameter is a specific value that is a multiple of the aforementioned third integer, and the first parameter is directly included in TDD-UL-DL-ConfigCommon, then bfdPeriodicityFactor is a specific value that is a multiple of the third integer. An example of the SBFD pattern in the first RRC signaling is as follows:
[0131]
[0132] In another embodiment of this application, the second parameter mentioned above represents the temporal location of one or two SBFD temporal resources in the TDD frame structure or TTD frame structure pattern.
[0133] Specifically, when there is a one-to-one correspondence between the SBFD patterns contained in TDD-UL-DL-ConfigCommon and the TDD frame structure patterns, the SBFD temporal resources are located within the TDD frame structure patterns. When there is one SBFD pattern in TDD-UL-DL-ConfigCommon corresponding to two TDD frame structure patterns, the SBFD temporal resources are located within the TDD frame structure.
[0134] If there is one set of second parameters, one or two SBFD time-domain resources can be configured. If there are two sets of second parameters, each set of second parameters can configure one or two SBFD time-domain resources, and a total of 2-4 SBFD time-domain resources can be configured.
[0135] In one embodiment of this application, if the TDD-UL-DL-ConfigCommon contains one 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.
[0136] If the SBFD pattern contained in the above TDD-UL-DL-ConfigCommon corresponds one-to-one with the TDD frame structure pattern, then the SBFD time-domain resource represented by the above second parameter is within the range of the above TDD frame structure pattern.
[0137] If a set of second parameters and a TDD frame structure pattern exist, the SBFD temporal 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 temporal resources exceeds the range of the TDD frame structure, the excess portion is invalid.
[0138] If there are two sets of second parameters and two TDD frame structure patterns, the SBFD time-domain resources configured for each set of second parameters are located in the TDD frame structure pattern corresponding to the SBFD pattern to which that set of second parameters belongs. If the length of the SBFD time-domain resources exceeds the range of the TDD frame structure pattern to which they belong, then the excess part is invalid.
[0139] If there is a set of second parameters and two TDD frame structure patterns, the SBFD time-domain resources configured by the second parameter can span across TDD frame structure patterns and be located at any position within 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.
[0140] Furthermore, if only one set of second parameters exists in TDD-UL-DL-ConfigCommon, then the second parameter can be included in an SBFD pattern within TDD-UL-DL-ConfigCommon. Alternatively, the second parameter may not be included in the SBFD pattern; in this case, the SBFD pattern may not be explicitly configured in TDD-UL-DL-ConfigCommon.
[0141] If there are two sets of second parameters in TDD-UL-DL-ConfigCommon, then the second parameters are contained in the two SBFD patterns within TDD-UL-DL-ConfigCommon respectively.
[0142] In one embodiment of this application, the second parameter includes a third parameter and a fourth parameter; when the TDD frame structure pattern and the SBFD pattern correspond one-to-one, the third parameter indicates the position of the start symbol of the SBFD time-domain resource in the TDD frame structure pattern; when one SBFD pattern corresponds to two TDD frame structure patterns, the third parameter indicates the position of the start symbol of the SBFD time-domain resource in the TDD frame structure; the fourth parameter is the symbol length of the SBFD time-domain resource.
[0143] Alternatively, the second parameter may include the third and fifth parameters. When the TDD frame structure pattern and the SBFD pattern correspond one-to-one, the fifth parameter indicates the position of the termination symbol of the SBFD time-domain resource in the TDD frame structure pattern. When one SBFD pattern corresponds to two TDD frame structure patterns, the fifth parameter indicates the position of the termination symbol of the SBFD time-domain resource in the TDD frame structure.
[0144] If the second parameter includes the third and fourth parameters, it means that the symbols of the fourth consecutive parameter length starting from the position indicated by the third parameter all belong to the SBFD time-domain resources.
[0145] If the second parameter includes the third and fifth parameters, it means that from the position indicated by the third parameter to the position indicated by the fifth parameter, all symbols belong to the SBFD time domain resources.
[0146] In addition, regardless of whether the first parameter contains the third and fourth parameters, or the third and fifth parameters, a pair of parameters must exist in pairs.
[0147] In one embodiment of this application, the third parameter is the order of the starting symbol in the TDD frame structure pattern or the symbols of the TDD frame structure, from front to back or from back to front. When the third parameter is from front to back, the starting symbol is the foremost symbol from front to back. When the third parameter is from back to front, the starting symbol is the foremost symbol from back to front.
[0148] Based on this, if the second parameter represents the temporal position of an SBFD temporal resource within the TDD frame structure or TDD frame structure pattern, then the second parameter includes a third parameter for the SBFD temporal resource. In this case, the third parameter of the SBFD temporal resource is the order of the start symbol of the SBFD temporal resource from front to back within the symbols of the TDD frame structure or TDD frame structure pattern.
[0149] Alternatively, if the second parameter represents the temporal position of the two SBFD temporal resources within the TDD frame structure or TDD frame structure pattern, then the second parameter includes two sets of parameters. Specifically, the second parameter includes a third parameter for both the first and second SBFD temporal resources. The first SBFD temporal resource precedes the second SBFD temporal resource. In this case, the third parameter for the first SBFD temporal resource is the order of its start symbol from front to back within the symbols of the TDD frame structure or TDD frame structure pattern. The third parameter for the second SBFD temporal resource is the order of its start symbol from back to front within the symbols of the TDD frame structure or TDD frame structure pattern.
[0150] Based on the foregoing embodiments, 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 temporal position of the two SBFD temporal resources in the TDD frame structure pattern, then an example of the SBFD pattern in TDD-UL-DL-ConfigCommon is as follows:
[0151]
[0152] Here, `startSymbolOfSbfd1` (SBFD start symbol 1) is the third parameter of the first SBFD time-domain resource. `nrofSbfdSymbols1` (SBFD symbol count 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 count 2) is the fourth parameter of the second SBFD time-domain resource.
[0153] Furthermore, in one embodiment of this application, if the first SBFD time-domain resource overlaps with the second SBFD time-domain resource, the first SBFD time-domain resource in the overlapping portion has a higher priority than the second SBFD time-domain resource.
[0154] That is, if there is an overlap between the configuration of the first SBFD time domain resource and the configuration of the second SBFD time domain resource in the second parameter, the overlapping part belongs to the first SBFD time domain resource.
[0155] In another embodiment of this application, symbols that overlap with conventional UL symbols in the first SBFD time-domain resource are invalid.
[0156] In other words, the configuration of the first SBFD time domain resources can only be applied to symbols other than the traditional UL symbols in the TDD frame structure.
[0157] Furthermore, for symbols other than traditional UL symbols, the effectiveness of the configuration of the first SBFD time-domain resource can be controlled by the sixth parameter included in the aforementioned TDD-UL-DL-ConfigCommon. When the sixth parameter is included in the aforementioned TDD-UL-DL-ConfigCommon, the sixth parameter indicates whether the first symbol in the aforementioned first SBFD time-domain resource that overlaps with a traditional DL symbol or a traditional F symbol is invalid. And / or, when the sixth parameter is not included in the aforementioned TDD-UL-DL-ConfigCommon, the first symbol that overlaps with the aforementioned traditional DL symbol or the aforementioned traditional F symbol is valid.
[0158] The sixth parameter mentioned above can be referred to as the first SBFD symbol configuration indicator parameter (sbfdIndicator1), and the sixth parameter is optional.
[0159] The above-mentioned traditional UL symbols are: the UL symbols contained in the above-mentioned TDD frame structure; the above-mentioned traditional DL symbols are: the DL symbols contained in the above-mentioned TDD frame structure; and the above-mentioned traditional F symbols are: the F symbols contained in the above-mentioned TDD frame structure.
[0160] In addition, if a sixth parameter exists, then 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.
[0161] When the sixth parameter is set to the second value, the first symbol that overlaps with the traditional DL symbol is invalid, while the first symbol that overlaps with the traditional F symbol is valid.
[0162] For example, the first value can be 0, and the second value can be 1. Of course, the first and second values can also be other values, and this application does not limit the specific values.
[0163] The above sbfdIndicator1 can be defined as: sbfdIndicator1 ENUMERATED{0,1}optional.
[0164] Similarly, in another embodiment of this application, symbols that overlap with traditional DL symbols in the second SBFD time-domain resource are invalid.
[0165] In other words, the configuration of the second SBFD time domain resources can only be applied to symbols other than traditional DL symbols in the TDD frame structure.
[0166] Furthermore, for symbols other than traditional DL symbols, the effectiveness of the configuration of the second SBFD time-domain resource can be controlled by the seventh parameter included in the aforementioned TDD-UL-DL-ConfigCommon. When the seventh parameter is included in the aforementioned TDD-UL-DL-ConfigCommon, this seventh parameter indicates whether the second symbol in the aforementioned second SBFD time-domain resource that overlaps with a traditional UL symbol or a traditional F symbol is invalid. And / or, when the seventh parameter is not included in the aforementioned TDD-UL-DL-ConfigCommon, the second symbol that overlaps with the aforementioned traditional UL symbol or the aforementioned traditional F symbol is valid.
[0167] The seventh parameter mentioned above can be referred to as the second SBFD symbol configuration indicator parameter (sbfdIndicator2), and the seventh parameter is optional.
[0168] In one embodiment of this application, when the seventh parameter is a third value, the second symbol that coincides with the conventional UL symbol is valid, and the second symbol that coincides with the conventional F symbol is invalid.
[0169] When the seventh parameter is 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.
[0170] For example, the third value mentioned above can be 0, and the fourth value can be 1. Of course, the third and fourth values can also be other values, and this application does not limit the specific values.
[0171] The above sbfdIndicator2 can be defined as: sbfdIndicator2 ENUMERATED{0,1}optional.
[0172] It should be noted that if the first SBFD time-domain resource and the second SBFD time-domain resource overlap, then in the overlapping part, 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.
[0173] 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 indicates the temporal location of the two SBFD temporal resources in the TDD frame structure pattern. An example of the SBFD pattern in TDD-UL-DL-ConfigCommon with sbfdIndicator1 and sbfdIndicator2 present is as follows:
[0174]
[0175] If TDD-UL-DL-ConfigCommon contains two TDD frame structure patterns and does not explicitly configure the SBFD pattern, an example of TDD-UL-DL-ConfigCommon with sbfdIndicator1 and sbfdIndicator2 present would be:
[0176]
[0177] If TDD-UL-DL-ConfigCommon contains two TDD frame structure patterns and one SBFD pattern, the second parameter is included in the aforementioned SBFD pattern. An example of TDD-UL-DL-ConfigCommon in the presence of sbfdIndicator1 and sbfdIndicator2 is as follows:
[0178]
[0179]
[0180] The following is based on Figure 5 and Figure 6 The specific example shown illustrates the location of SBFD time-domain resources in the TDD frame structure pattern.
[0181] See Figure 5 This is a schematic diagram of a third type of SBFD time-domain resource provided in an embodiment of this application.
[0182] The diagram includes 10 time slots, from time slot 0 to time slot 9. Time slots 0-4 form the first TDD frame structure pattern, which can be represented as DDSUU. This indicates that the time slots in this TDD frame structure pattern are, in order, time slots D, S, U, and U. Time slot D is configured with all DL symbols, hence represented as DL in the diagram. Time slot S is configured with all F symbols, hence represented as F in the diagram. Time slot U is configured with all UL symbols, hence represented as UL in the diagram. Time slots 5-9 form the second TDD frame structure, which can be represented as DDDSU. This indicates that the time slots in this TDD frame structure pattern are, in order, time slots D, S, and U. Time slot D is configured with all DL symbols, hence represented as DL in the diagram. Time slot S is configured with all F symbols, hence represented as F in the diagram. Time slot U is configured with all UL symbols, hence represented as UL in the diagram. Figure 4 The period of the TDD frame structure is 5ms. Each of the two TDD frame structure patterns contains one SBFD time-domain resource.
[0183] The third parameter of the first SBFD time-domain resource is: startSymbolOfSbfd1 = 21 (slot 0 contains 14 symbols, and the first SBFD time-domain resource in slot 1 contains 7 symbols before it), and the fourth parameter is: nrofSbfdSymbols1 = 28. Since sbfdIndicator1 is not configured, the first SBFD time-domain resource is effective in both traditional DL symbols and traditional F symbols, but not in traditional UL symbols (such as the first 7 symbols in slot 3).
[0184] The third parameter of the second SBFD time-domain resource is: startSymbolOfSbfd2 = 0 (starting symbol order from back to front), and the fourth parameter is: nrofSbfdSymbols2 = 35. sbfdIndicator2 = 0. This means the second SBFD time-domain resource is only effective in traditional UL symbols, and not in traditional DL symbols or traditional F symbols. For example, the last 7 symbols in time slot 7 are still traditional DL symbols, and all symbols in time slot 8 are still traditional F symbols.
[0185] See Figure 6 This is a schematic diagram of a fourth type of SBFD time-domain resource provided in an embodiment of this application.
[0186] The diagram includes 10 time slots, from time slot 0 to time slot 9. Figure 6 TDD frame structure pattern and Figure 4 The TDD frame structure pattern is the same as that in the previous example, so it will not be described again here. Figure 6 The TDD frame structure shown contains an SBFD time-domain resource.
[0187] 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 the SBFD time-domain resource is effective in both traditional DL symbols and traditional F symbols, but not in traditional UL symbols. For example, all symbols in slots 3 and 4 remain traditional UL symbols.
[0188] As can be seen from the above, the embodiments of this application configure a conflict handling mechanism when there is an overlap and conflict between SBFD time domain resources and traditional time slots in TDD frame structure or TDD frame structure pattern. Furthermore, by configuring optional sixth and / or seventh parameters, the overlap and conflict can be further processed. For the two SBFD time domain resources configured by the second parameter, a variety of different conflict handling mechanisms are provided.
[0189] In another embodiment of this application, the base station may also perform the following step B to implement user-level dynamic SBFD time-domain resource configuration for a specific UE.
[0190] Step B: Send the second RRC signaling to the aforementioned UE.
[0191] Among them, the TDD-UL-DL-ConfigDedicated in the second RRC signaling includes an eighth parameter, which is used to configure symbols in some time slots of the TDD frame structure as SBFD symbols, and the SBFD symbols have SBFD subband resources.
[0192] 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 configurations, respectively. Therefore, they need to be included in different first and second RRC signaling messages and sent to the UE separately.
[0193] Additionally, it should be noted that, in the presence of the sixth and / or seventh parameters, the configuration of the time slots by the aforementioned eighth parameter conforms to the rules defined by the aforementioned sixth and / or seventh parameters.
[0194] The eighth parameter is used to configure SBFD symbols within a time slot, on a time slot-by-time basis.
[0195] In one embodiment of this application, the eighth parameter above includes a ninth parameter, which indicates that all symbols in the specified DL slot and / or S slot in the TDD frame structure are configured as first SBFD symbols.
[0196] and / or
[0197] The eighth parameter mentioned above includes the tenth parameter, which means: configure all symbols in the specified UL slot and / or S slot in the TDD frame structure as the second SBFD symbols;
[0198] and / or
[0199] The eighth parameter mentioned above includes an eleventh parameter, which means: configuring a portion of the symbols specified in the DL slot and / or S slot in the TDD frame structure as the first SBFD symbol;
[0200] and / or
[0201] The eighth parameter mentioned above includes a twelfth parameter, which indicates that a portion of the symbols specified in the UL slot and / or S slot in the TDD frame structure are configured as the second SBFD symbols.
[0202] In one scenario, the eighth parameter can configure all symbols in a portion of the time slots of a TDD frame structure as SBFD symbols.
[0203] In one embodiment of this application, the eighth parameter includes a ninth parameter, which indicates that all symbols in the specified DL slot and / or S slot in the TDD frame structure are configured as the first SBFD symbols.
[0204] For example, the ninth parameter mentioned above can be referred to as allSbfd1 (all SBFD1).
[0205] In another embodiment of this application, the eighth parameter includes a tenth parameter, which indicates that all UL symbols in the UL slot and / or S slot specified in the TDD frame structure are configured as second SBFD symbols.
[0206] For example, the tenth parameter mentioned above can be called allSbfd2 (all SBFD2).
[0207] In another case, the eighth parameter can configure some symbols within a certain time slot in the TDD frame structure as SBFD symbols.
[0208] In one embodiment of this application, the eighth parameter includes an eleventh parameter, which indicates that a portion of the symbols specified in the DL slot and / or S slot in the TDD frame structure are configured as the first SBFD symbols.
[0209] The eleventh parameter may include: the position of the starting symbol in the specified partial symbols in the DL time slot and / or S time slot, and the length of the specified partial symbols. The eleventh parameter is invalid for the configuration of symbols that exceed the time slot.
[0210] Specifically, the position of the starting symbol in the UL time slot and / or S time slot of the specified partial symbols can be represented as: startSymbolOfSbfd1, where the length of the specified partial symbols is nrofSbfdSymbols1. This indicates that starting from the startSymbolOfSbfd1th symbol in this time slot, a total of nrofSbfdSymbols1 symbols are configured as SBFD symbols.
[0211] Furthermore, it should be noted that when both a first SBFD symbol and a second SBFD symbol exist in the same time slot, the portion of the first SBFD symbol that overlaps with the second SBFD symbol in the same time slot is configured according to the first SBFD symbol. That is, the overlapping portion of the first SBFD symbol and the second SBFD symbol belongs to the first SBFD symbol.
[0212] Additionally, the eleventh parameter may also include: the position of the start symbol in the UL time slot and / or S time slot of the specified partial symbols, and the position of the end symbol in the time slot of the specified partial symbols.
[0213] In another embodiment of this application, the eighth parameter includes a twelfth parameter, which indicates that a portion of the symbols specified in the UL slot and / or S slot in the TDD frame structure are configured as the second SBFD symbols.
[0214] The twelfth parameter may include: the position of the starting symbol in the specified partial symbol in the UL time slot and / or S time slot, and the length of the specified partial symbol. The twelfth parameter is invalid for the configuration of symbols that exceed the time slot.
[0215] Specifically, the position of the starting symbol in the UL time slot and / or S time slot of the specified partial symbols can be represented as: startSymbolOfSbfd2, where the length of the specified partial symbols is nrofSbfdSymbols2. This indicates that starting from the startSymbolOfSbfd2th symbol in this time slot, nrofSbfdSymbols2 consecutive symbols are configured as SBFD symbols.
[0216] Additionally, the twelfth parameter may also include: the position of the start symbol in the UL time slot and / or S time slot of the specified partial symbols, and the position of the end symbol in the time slot of the specified partial symbols.
[0217] See Figure 7 This is a schematic diagram of the fifth type of SBFD time-domain resource provided in an embodiment of this application.
[0218] Figure 7 It contains two time slots: time slot 1 and time slot 2. Each time slot contains symbols 0 to 13, for a total of 14 symbols. Figure 6 The diagram illustrates the result of configuring user-level SBFD time-domain resources using the second RRC signaling. Time slot 1 is a D time slot, and time slot 2 is an S time slot, with all symbols in the S time slot being F symbols. For time slot 1, `allSbfd1` is configured, assigning all symbols in time slot 1 as SBFD time-domain resources. Other parameters are not configured. In time slot 2, `startSymbolOfSbfd1` is configured to 1, and `nrofSbfdSymbols1` is configured to 12, thus configuring the first 12 symbols in time slot 2 as SBFD time-domain resources.
[0219] As can be seen from the above, in the scheme provided by the embodiments of this application, the base station can further configure the UE's SBFD symbol through the eighth parameter in TDD-UL-DL-ConfigDedicated contained in the second RRC signaling. This enables dynamic configuration at the user level for a specific UE and flexible configuration of the UE's SBFD time-domain resources.
[0220] 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 the traditional time slots in the TDD frame structure. In this case, the restoration process can be achieved through the following embodiments.
[0221] In one embodiment of this application, the base station may further perform the following step C.
[0222] Step C: Send the third RRC signaling to the UE.
[0223] The aforementioned third RRC signaling includes a thirteenth parameter, which is used to control the UE to restore the configuration of time domain resources to the state before receiving the aforementioned second RRC signaling.
[0224] The aforementioned thirteenth parameter can be referred to as revertToOriginal. When the UE receives a third RRC signaling message containing the thirteenth parameter, the configuration of the SBFD time domain resources is restored to the state before the second RRC signaling message was received.
[0225] The aforementioned thirteenth parameter can be included in TDD-UL-DL-ConfigDedicated. The thirteenth parameter can be included in the same RRC signaling's TDD-UL-DL-ConfigDedicated along with any one or more of the aforementioned eighth to twelfth parameters. In this case, the second and third RRC signaling are the same RRC signaling.
[0226] Alternatively, the thirteenth parameter may be contained separately in the TDD-UL-DL-ConfigDedicated section of an RRC signaling message. In this case, the second and third RRC signaling messages are not the same RRC signaling message.
[0227] In one embodiment of this application, the eighth to thirteenth parameters can be configured in a structure parameter, 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.
[0228] An example of TDD-UL-DL-ConfigDedicated is as follows:
[0229]
[0230]
[0231] Alternatively, another example of TDD-UL-DL-ConfigDedicated is:
[0232]
[0233] Among them, slotSpecificConfigurationsToAddModList-SBFD (SBFD-specific configuration slot set) represents the set of slots for which SBFD symbols are to be configured.
[0234] In another embodiment of this application, in order to achieve configuration recovery, the base station may also perform the following step D.
[0235] Step D: Send the fourth RRC signaling to the UE.
[0236] Among them, the aforementioned fourth RRC signaling includes the fourteenth parameter, which is used to control the UE to restore the configuration of the time domain resources to the state before the configuration of the SBFD time domain resources.
[0237] The fourteenth parameter mentioned above can be represented as slotSpecificConfigurationsToReleaseList, which releases a series of time slots in the SBFD time domain resources, restoring them to the original state of the TDD frame structure.
[0238] The fourteenth parameter mentioned above can be included in TDD-UL-DL-ConfigDedicated. The fourteenth parameter can be included in the same RRC signaling TDD-UL-DL-ConfigDedicated along with any one or more of the eighth to twelfth parameters mentioned above. In this case, the second RRC signaling and the fourth RRC signaling are the same RRC signaling.
[0239] Alternatively, the fourteenth parameter may be included separately in the TDD-UL-DL-ConfigDedicated section of an RRC signaling message. In this case, the second and fourth RRC signaling messages are not the same RRC signaling message.
[0240] An example of TDD-UL-DL-ConfigDedicated is as follows:
[0241]
[0242]
[0243] In summary, the embodiments of this application specify in detail how to configure SBFD time-domain resources through semi-static (cell-level) or dynamic (user-level) methods. Through these embodiments, SBFD time-frequency resources can be configured explicitly and flexibly based on current TDD technology. This integrates the configuration of SBFD time-frequency resources with the current TDD frame structure, facilitating the practical implementation of SBFD technology.
[0244] Corresponding to the aforementioned time-domain resource configuration method applied to base stations, this application also provides a time-domain resource configuration method applied to UEs.
[0245] This application provides a time-domain resource configuration method, applied to a UE, see [link / reference]. Figure 8 This is a flowchart illustrating another time-domain resource allocation method provided in an embodiment of this application. The method includes the following steps E-F.
[0246] Step E: Receive the first RRC signaling sent by the base station;
[0247] The first RRC signaling includes Time Division Duplex-Uplink-Downlink-Common Configuration (TDD-UL-DL-ConfigCommon), which includes a TDD frame structure pattern and an SBFD pattern. The TDD frame structure pattern is used to configure the TDD frame structure, and the SBFD pattern is used to configure SBFD time-domain resources. The SBFD pattern carries a first parameter and a second parameter. The first parameter represents the period of the SBFD time-domain resources, and the second parameter represents the time-domain position of the SBFD time-domain resources in the TDD frame structure or the TDD frame structure pattern.
[0248] Step F: Configure the TDD frame structure and SBFD time domain resources according to the TDD frame structure pattern, SBFD pattern, first parameter and second parameter.
[0249] As can be seen from the above, in the scheme provided by the embodiments of this application, the base station sends a cell-level first RRC signaling to the UE. The first RRC signaling includes a first parameter and a second parameter of 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, after the UE receives the first RRC signaling, it can configure the SBFD time domain resource based on the above-mentioned first parameter and second parameter, thereby realizing SBFD communication between the base station and the UE.
[0250] In one embodiment of this 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.
[0251] or
[0252] The TDD-UL-DL-ConfigCommon contains two TDD frame structure patterns and two SBFD patterns that correspond one-to-one. The period duration represented by the first parameter is a second integer multiple of the sum of the periods configured in the two TDD frame structure patterns.
[0253] or
[0254] The TDD-UL-DL-ConfigCommon contains one 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. The period duration represented by the first parameter is the third integer multiple of the sum of the periods configured in the two TDD frame structure patterns.
[0255] In one embodiment of this application, the first parameter is in the form of: the value of the period duration or a specific value of the multiple between the period duration and the TDD frame structure duration.
[0256] In one embodiment of this application, the second parameter represents the temporal location of one or two SBFD temporal resources in the TDD frame structure or TDD frame structure pattern.
[0257] In one embodiment of this application, the second parameter includes a third parameter and a fourth parameter; when the TDD frame structure pattern and the SBFD pattern correspond one-to-one, the third parameter indicates the position of the start symbol of the SBFD time-domain resource in the TDD frame structure pattern; when one SBFD pattern corresponds to two TDD frame structure patterns, the third parameter indicates the position of the start symbol of the SBFD time-domain resource in the TDD frame structure; the fourth parameter is the symbol length of the SBFD time-domain resource.
[0258] Alternatively, the second parameter includes the third parameter and the fifth parameter; when the TDD frame structure pattern and the SBFD pattern correspond one-to-one, the fifth parameter indicates the position of the termination symbol of the SBFD time domain resource in the TDD frame structure pattern; when one SBFD pattern corresponds to two TDD frame structure patterns, the fifth parameter indicates the position of the termination symbol of the SBFD time domain resource in the TDD frame structure.
