Description

Resource configuration method, device and communication system Technical Field

[0001] The present application relates to the field of communication technology. Background Art

[0002] In traditional technologies, uplink transmissions in time-division duplexing (TDD) bands can only occur during the uplink time period. When limited or fewer uplink time periods are allocated, uplink coverage and capacity are limited, and latency is high. In frequency-division duplexing (FDD) bands, uplink transmissions can only occur on the uplink carrier. When limited or smaller uplink carriers are allocated, uplink coverage and capacity are also limited, and latency is high.

[0003] It should be noted that the above introduction to the technical background is merely for the purpose of providing a clear and complete description of the technical solutions of this application and facilitating understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0004] Summary of the Invention

[0005] In order to improve the capacity and coverage of uplink transmission and reduce the latency of uplink transmission, in the downlink frequency band of the TDD frequency band or the FDD frequency band, the network equipment can operate in full-duplex mode at certain time positions, for example, the network equipment simultaneously receives and transmits in different frequency domain resources in the corresponding carrier (of the downlink frequency band of the TDD frequency band or the FDD frequency band). This working mode is called, for example, SubBand non-overlapping Full Duplex (SBFD), but is not limited to this. For the terminal device, it needs to know in which time domain resources the network device receives and transmits simultaneously, in which part of the frequency domain resources a set receives and in which part of the frequency domain resources it transmits, and thus receives or sends signals in the corresponding resources. In addition, some terminal devices may only be able to send or receive in the above-mentioned carrier at the same time, and it is also necessary to know which time domain resources in the above-mentioned time domain resources should be sent and which time domain resources should be received. However, there is currently no specific indication method.

[0006] In response to at least one of the above problems, embodiments of the present application provide a resource configuration method, device, and communication system.

[0007] According to one aspect of an embodiment of the present application, a resource configuration method is provided, including:

[0008] The terminal device receives information indicating the first time domain resource and information indicating the first frequency domain resource and / or the second frequency domain resource, and / or receives information indicating the link direction of the first time domain resource;

[0009] Among them, in the first time domain resource, the first frequency domain resource is used for uplink and the second frequency domain resource is used for downlink.

[0010] According to another aspect of an embodiment of the present application, a resource configuration apparatus is provided, configured in a terminal device, the apparatus comprising:

[0011] a receiving unit configured to receive information indicating the first time domain resource and information indicating the first frequency domain resource and / or the second frequency domain resource, and / or receive information indicating a link direction of the first time domain resource;

[0012] Among them, in the first time domain resource, the first frequency domain resource is used for uplink and the second frequency domain resource is used for downlink.

[0013] According to another aspect of an embodiment of the present application, a resource configuration method is provided, including:

[0014] The network device sends information indicating the first time domain resource and information indicating the first frequency domain resource and / or the second frequency domain resource, and / or information indicating the link direction of the first time domain resource;

[0015] Among them, in the first time domain resources, the first frequency domain resources are used for uplink and the second frequency domain resources are used for downlink.

[0016] According to another aspect of an embodiment of the present application, a resource configuration apparatus is provided, configured on a network device, including:

[0017] a sending unit configured to send information indicating the first time domain resource and information indicating the first frequency domain resource and / or the second frequency domain resource, and / or information indicating a link direction of the first time domain resource;

[0018] Among them, in the first time domain resources, the first frequency domain resources are used for uplink and the second frequency domain resources are used for downlink.

[0019] According to another aspect of an embodiment of the present application, a communication system is provided, including:

[0020] A network device, which sends information indicating the first time domain resource and information indicating the first frequency domain resource and / or the second frequency domain resource, and / or information indicating the link direction of the first time domain resource;

[0021] A terminal device that receives information indicating a first time domain resource and information indicating a first frequency domain resource and / or a second frequency domain resource, and / or receives information indicating a link direction of the first time domain resource; wherein, in the first time domain resource, the first frequency domain resource is used for uplink and the second frequency domain resource is used for downlink.

[0022] One of the beneficial effects of the embodiments of the present application is that a terminal device obtains the resources of the network device operating in full-duplex mode based on information from the network device. As a result, the network device can operate in full-duplex mode (simultaneously receiving and transmitting), and the terminal device can also use the corresponding resources to transmit and receive signals when the network device operates in full-duplex mode. This can improve the capacity and coverage of uplink transmission, reduce the latency of uplink transmission, and improve resource allocation flexibility and resource utilization.

[0089] --Subcarrier spacing

[0090] The frequency position of a subcarrier refers to, for example, the center frequency of the subcarrier. The subcarrier spacing refers to, for example, the spacing between the frequency domain positions of two adjacent subcarriers.

[0091] The subcarrier spacing in the frequency domain is configurable. The candidate subcarrier spacings are shown in Table 1 below. When the subcarrier spacing is 60 kHz, either an extended or normal cyclic prefix (CP) can be applied, while other subcarrier spacings can use a normal CP. However, this is not limited to these options and other SCSs can be supported, using either an extended or normal CP. Available subcarrier spacings can be defined for different frequency ranges, bands, or carriers.

[0092] The smallest / lowest SCS is, for example, the SCS with the smallest SCS configuration μ and / or SCS size Δf. The largest / highest SCS is, for example, the SCS with the largest SCS configuration μ and / or SCS size Δf.

[0093] Table 1

[0094] --Time slot

[0095] The number of OFDM symbols per slot, the number of slots per frame, and the number of slots per subframe vary according to the subcarrier spacing or cyclic prefix, as shown in Table 2 (for normal cyclic prefix) and Table 3 (for extended cyclic prefix):

[0098] The following describes various embodiments of the present application in conjunction with the accompanying drawings. These embodiments are merely exemplary and are not intended to limit the present application. In the embodiments of the present application, the contents in brackets indicate that they are optional.

[0099] Embodiments of the first aspect

[0100] An embodiment of the present application provides a resource configuration method, which is described from the perspective of a terminal device.

[0101] FIG2 is a schematic diagram of a resource configuration method according to an embodiment of the present application. As shown in FIG2 , the method includes:

[0102] 201. The terminal device receives information indicating a first time domain resource and information indicating a first frequency domain resource and / or a second frequency domain resource, and / or receives information indicating a link direction of the first time domain resource; wherein, in the first time domain resource, the first frequency domain resource is used for uplink and the second frequency domain resource is used for downlink.

[0103] It is worth noting that FIG2 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG2 above.

[0104] In some embodiments, the terminal device may be an SBFD-aware device; the present application is not limited thereto. For example, during an initial access process and / or a random access process and / or during capability information reporting, the terminal device indicates to the network device that the terminal device is an SBFD-aware device (SBFD-aware UE).

[0105] In some embodiments, the first time domain resource is a time domain resource used for (supporting) full-duplex (e.g., SBFD) operation, and the second time domain resource is a time domain resource not used for (supporting) full-duplex operation (or, not used for full-duplex operation, e.g., non-SBFD), and the time positions of the first time domain resource and the second time domain resource are different.

[0106] In some embodiments, in the first time domain resources, the network device simultaneously receives and transmits in different frequency domain resources in the corresponding carrier (downlink frequency band of TDD frequency band or FDD frequency band), and in the second time domain resources, the network device only receives or transmits in the carrier.

[0107] In some embodiments, the first time domain resources refer to time domain resources having / corresponding to SBFD subbands, or in other words, time domain resources where SBFD subbands are located, and the second time domain resources refer to time domain resources not having / corresponding to SBFD subbands. SBFD subbands include, for example, DL subband(s) and / or uplink subband(s).

[0108] In some embodiments, the information indicating the first time domain resource may indicate the first time domain resource based on the first SCS and / or the first CP, such as the information indicating the first time domain resource indicates a time resource unit belonging to the first time domain resource. For example, the first SCS is referenceSubcarrierSpacing in TDD-UL-DL-Config Common, or in other words, the SCS indicated by referenceSubcarrierSpacing in TDD-UL-DL-ConfigCommon. The first CP is a normal CP.

[0109] In some embodiments, the information indicating the first time domain resource is carried by higher layer signaling and / or PHY (physical layer) signaling, or is sent through higher layer signaling and / or PHY signaling, or is included in higher layer signaling and / or PHY signaling.

[0110] In some embodiments, the information for indicating the first time domain resource is cell-specific (can also be replaced by public), wherein cell-specific means that the parameter settings for different UEs in the cell are the same (for example, broadcast through system information or sent through dedicated RRC signaling but the content sent for different UEs is the same); for example, if the information for indicating the first time domain resource includes an IE for indicating the first time domain resource, and the IE is included in an IE or message dedicated to configuring cell-specific parameters, it means that the information for indicating the first time domain resource is cell-specific. In some cases, even if the information for indicating the first time domain resource is included in a UE specific / dedicated IE or message, it can also be cell-specific. For example, the information for indicating the first time domain resource is included in a system message and / or a public service cell configuration. In some embodiments, the information for indicating the first time domain resource indicates a time resource unit belonging to a time resource unit of the first time domain resource.

[0111] In some embodiments, the method may further include: determining that a second time resource unit corresponding to the second SCS and / or the second CP belongs to the first time domain resource or the second time domain resource. For example, it may be determined based on the first time resource unit that the second time resource unit (time slot and / or symbol) belongs to the first time domain resource or the second time domain resource.

[0112] In some embodiments, the second SCS is, for example, the SCS of an (activated) DL BWP or an (activated) UL BWP, or the SCS of a DL SCS specific carrier or a UL SCS specific carrier, but is not limited thereto. It can also be said that the information indicating the first time domain resource indirectly indicates the first time domain resource corresponding to the second SCS and / or the first time domain resource for the BWP or SCS specific carrier.

[0113] In some implementations, the second CP is, for example, the CP of an (activated) DL BWP or an (activated) UL BWP, but is not limited thereto. The second CP may be a normal cyclic prefix (NCP) or an extended cyclic prefix (ECP) as indicated by the cyclic prefix type information in the BWP configuration information.

[0114] In some embodiments, there is a first time interval between the first time domain resource and the second time domain resource, or there is a second time interval between sending an uplink signal in the first time domain resource and sending an uplink signal in the second time domain resource, and / or there is a third time interval between receiving a downlink signal in the first time domain resource and receiving a downlink signal in the second time domain resource, the first time interval and / or the second time interval is not less than the (minimum) time period for the terminal device to switch bandwidth and / or beam and / or transmit power, and the first time interval and / or the third time interval is not less than the (minimum) time period for the terminal device to switch bandwidth and / or beam. The (minimum) time period can be predefined or reported, and the embodiments of the present application are not limited to this.

[0115] In some embodiments, the information for indicating the first time domain resource and the information for indicating the first frequency domain resource and / or the second frequency domain resource, and / or the information received for indicating the link direction of the first time domain resource, can be configuration information and / or indication information configured and / or indicated together, or can be configuration information and / or indication information configured and / or indicated separately or separately. The following description is given using the first indication information to the fifth indication information as an example, but the present application is not limited thereto. For example, other names or terms may be used, such as the first configuration or uplink and downlink configuration (e.g., TDD uplink and downlink configuration) described later.

[0116] In some embodiments, the first time interval and / or the second time interval and / or the third time interval are predefined and / or reported and / or indicated, for example, the terminal device carries information for indicating the above time intervals in the capability information sent to the network device. The first indication information and / or the second indication information may also indicate the first time interval and / or the second time interval and / or the third time interval, or the first time interval and / or the second time interval and / or the third time interval may also be indicated by fifth indication information, and the embodiments of the present application are not limited thereto.

[0117] In some embodiments, the first time domain resource and / or the second time domain resource and / or the time interval includes one or more time resource units.

[0118] In some embodiments, the time resource unit includes, for example, a symbol and / or a slot and / or a sub-slot and / or a mini-slot and / or a symbol group and / or a slot group and / or a subframe and / or a frame and / or ms and / or s, etc., but is not limited thereto. For example, the number of symbols included in a sub-slot and a mini-slot is less than or equal to the number of time slots included in a time slot, a symbol group includes one or more (continuous or discontinuous) symbols, and a slot group includes one or more (continuous or discontinuous) time slots, but is not limited thereto.

[0119] In some embodiments, the first time domain resources may also be referred to as SBFD resources, and the second time domain resources may also be referred to as non-SBFD resources. SBFD resources may include, for example, SBFD time resource units, such as SBFD time slots and / or symbols, and non-SBFD resources may include, for example, non-SBFD time resource units, such as non-SBFD time slots and / or symbols.

[0120] In some embodiments, a time slot may include SBFD symbols and non-SBFD symbols, or only SBFD symbols, or only non-SBFD symbols.

[0121] In some embodiments, the terminal device may also receive third indication information and / or fourth indication information, where the third indication information is cell-specific and the fourth indication information is UE-specific, and the third indication information and / or the fourth indication information are, for example, sent via high-layer signaling or carried by high-layer signaling or included in high-layer signaling. For example, the third indication information is common TDD uplink and downlink configuration information, tdd-UL-DL-ConfigurationCommon or TDD-UL-DL-ConfigCommon, and the fourth indication information is dedicated TDD uplink and downlink configuration information, tdd-UL-DL-ConfigurationDedicated or TDD-UL-DL-ConfigDedicated.

[0122] In some embodiments, the third indication information and / or the fourth indication information is used to indicate the periodic transmission direction of the time domain resources, for example, indicating whether a time resource unit (eg, time slot and / or symbol) in a period is downlink or uplink.

[0123] For example, the third indication information includes at least one of the following information: subcarrier spacing (SCS), pattern 1, pattern 2, and for each pattern, at least one of the following information: period size (period of the pattern), number of downlink time slots (number of consecutive downlink time slots at the starting position in the pattern), number of downlink symbols (number of consecutive downlink symbols at the starting position in the time slot), number of uplink time slots (number of consecutive uplink time slots at the ending position in the pattern), and number of uplink symbols (number of consecutive downlink symbols at the ending position in the time slot). For pattern 1, a time slot configuration period P may be provided, and for pattern 2, a time slot configuration period P2 may be provided.

[0124] For example, the fourth indication information includes at least one item of the following information: time slot index, symbol configuration, the symbol configuration includes allDownlink (indicating that the symbols in the corresponding time slot are all downlink) or allUplink (indicating that the symbols in the corresponding time slot are all uplink) or explicit (indicating that the corresponding time slot starts with nrofDownlinkSymbols downlink symbols and ends with nrofUplinkSymbols uplink symbols. If nrofDownlinkSymbols is not included, it means that there is no downlink symbol at the beginning of the time slot. If nrofUplinkSymbols is not included, it means that there is no uplink symbol at the end of the time slot, and the remaining symbols are flexible symbols).

[0125] In some embodiments, if a time slot and / or part of the symbols in a time slot are not indicated as downlink or uplink by the third indication information and / or the fourth indication information (including: the third indication information and the fourth indication information are not provided, or the third indication information and / or the fourth indication information are provided but the indication information does not indicate that the time slot or the part of the symbols are either downlink or uplink), the symbols in the time slot and / or the part of the symbols are, for example, called flexible symbols. In other words, the third indication information and / or the fourth indication information indicate that the time slot and / or the symbol are flexible.

[0126] In some embodiments, the first indication information and / or the second indication information indicates a time resource unit belonging to the first time domain resource and / or a time resource unit belonging to the second time domain resource, or in other words, indicates whether the time resource unit belongs to the first time domain resource or the second time domain resource.

[0127] In some embodiments, the first indication information and / or the second indication information is carried by high-layer signaling and / or PHY (physical layer) signaling, or is sent through high-layer signaling and / or PHY signaling, or is included in high-layer signaling and / or PHY signaling.

[0128] In some embodiments, the first indication information is cell-specific (or public), and the second indication information is UE-specific (or dedicated). Cell-specific means that the parameter settings for different UEs in the cell are the same (for example, broadcasted via system information or sent via dedicated RRC signaling, but the content sent to different UEs is the same), and UE-specific means that the parameter settings for different UEs in the cell can be different (for example, sent via dedicated RRC signaling, and the content sent to different UEs can be the same or different).

[0129] For example, if the first indication information includes that the IE of the first indication information is included in an IE or message dedicated to configuring cell-specific parameters, it indicates that the first indication information is cell-specific. If the second indication information includes that the IE of the second indication information is included in an IE or message dedicated to configuring UE specific / dedicated parameters, it indicates that the second indication information is UE-specific. However, not limited to this, in some cases, even if the first indication information is included in the UE specific / dedicated IE or message, it may also be cell-specific. For example, the first indication information is included in a system message and / or a public service cell configuration, and the second indication information is included in a dedicated RRC message and / or a service cell configuration. In some embodiments, the first indication information and / or the second indication information indicates a time resource unit belonging to a first time domain resource and / or a time resource unit belonging to a second time domain resource.

[0130] In some embodiments, the first time domain resource and / or the second time domain resource are periodic, and the first indication information and / or the second indication information indicates the position of the first time domain resource and / or the second time domain resource in a period, or in other words, indicates the first time domain resource in a period.

[0131] In some embodiments, the period is predefined or indicated.

[0132] In some embodiments, the first indication information and / or the second indication information includes information for indicating at least one of the following: a period, an SCS, a position of the first time domain resource in a period; a position of the second time domain resource in a period; a time interval (the aforementioned first time interval and / or second time interval and / or third time interval); information for indicating an associated TDD pattern (for example, pattern1 or pattern2).

[0133] For example, the position of the first time domain resource in the cycle includes: the first starting time slot / first time slot offset (in the cycle), and / or, the first starting symbol / first symbol offset (in the cycle or in the first starting time slot), and / or the first time slot number (in the cycle), and / or the first symbol number (in the cycle or in the first ending time slot), and / or the first ending symbol / second symbol offset (in the cycle or in the first ending time slot), and / or the first ending time slot / second time slot offset (in the cycle).

[0134] For example, the position of the second time domain resource in the one cycle includes: the second end slot / third time slot offset (in the cycle), and / or the second end symbol (in the cycle or in the second end slot), and / or the second time slot number (in the cycle), and / or the second symbol number (in the cycle or in the second end slot), and / or the second start time slot / fourth time slot offset (in the cycle), and / or the second start symbol (in the cycle or in the second start time slot), and / or the third time slot number (in the cycle), and / or the third symbol number (in the cycle or in the second start time slot).

[0135] In the above example, for the second time domain resource located before the first time domain resource, the second time domain resource uses the start of the cycle as its starting position, but the embodiments of the present application are not limited to this. For example, its starting time slot / time slot offset, and / or starting symbol / symbol offset (in the starting time slot in the cycle) can also be indicated by the first indication information and / or the second indication information. The embodiments of the present application are not limited to this.

[0136] In the above example, for the second time domain resource located after the second time domain resource, the second time domain resource has the end of the cycle as its end position, or the start of the last uplink time slot / symbol in the cycle as its starting position, but the embodiments of the present application are not limited to this. For example, the end slot / time slot offset and / or the end symbol / symbol offset (in the end slot in the cycle) can also be indicated by the first indication information and / or the second indication information. The embodiments of the present application are not limited to this.

[0137] In some embodiments, the period is, for example, a pattern period or a time slot configuration period or a period indicated otherwise, wherein the pattern period refers, for example, to the period of the corresponding pattern, indicated by the dl-UL-TransmissionPeriodicity in the TDD-UL-DL-Pattern, that is, the period corresponding to the above-mentioned P or P2. When only pattern 1 is configured, the time slot configuration period is the period of pattern 1. When pattern 1 and pattern 2 are configured, the time slot configuration period is the total period of pattern 1 + pattern 2, corresponding to the above-mentioned period of P + P2.

[0138] In some embodiments, first time domain resources are configured for different patterns. For example, when pattern 1 and pattern 2 are configured (i.e., the third indication information provides pattern 1 and pattern 2), first time domain resources are configured for pattern 1 and pattern 2, respectively, for example, the first time domain resources are configured within the resources of pattern 1 and within the resources of pattern 2, respectively.

[0139] In some embodiments, the first time domain resources and / or the second time domain resources are configured only for pattern 1 or only for pattern 2. For example, when both pattern 1 and pattern 2 are configured, the first time domain resources are configured only within the resources of pattern 1, or only within the resources of pattern 2. Alternatively, only pattern 1 is configured and the first time domain resources are configured within its resources.

[0140] In some embodiments, the first indication information and / or the second indication information directly / explicitly indicates the first time domain resource and / or directly / explicitly indicates the second time domain resource, and / or indirectly / implicitly indicates the first time domain resource or the second time domain resource. For example, the first time domain resource may be indicated, and the second time domain resource may be indirectly determined based on the first time domain resource, or vice versa. Alternatively, for example, when the second indication information is fourth indication information, the first time domain resource or the second time domain resource may be indirectly determined based on the uplink or downlink time domain resource indicated by the fourth indication information.

[0141] In some embodiments, the second indication information does not indicate the first time domain resource indicated by the first indication information as a second time domain resource (for example, for a time resource unit indicated as a first time domain resource by the first indication information, the second indication information must indicate the time resource unit as a first time domain resource), and / or does not indicate as a first time domain resource the resources in the second time domain resource indicated by the first indication information that overlap with the time domain resources that are not indicated as downlink or uplink by the third indication information (or does not indicate as a first time domain resource the resources in the second time domain resource indicated by the first indication information that overlap with the resources indicated as flexible by the third indication information), but is not limited to this.

[0142] In some embodiments, the third indication information and / or the fourth indication information is also used to indicate the first time domain resource and / or the second time domain resource. For example, the first indication information may be included in the third indication information, such as the TDD-UL-DL-ConfigCommon IE or the TDD-UL-DL-Pattern IE. For example, when included in the TDD-UL-DL-Pattern IE, it may optionally exist or conditionally optionally exist. If it does not exist, the first time domain resource is not included in the corresponding pattern. Among them, conditionally optional existence, for example, includes: for pattern1, optional existence, otherwise it does not exist. Or the first indication information is the third indication information. For example, the second indication information may be included in the fourth indication information, or the second indication information is the fourth indication information.

[0143] In some embodiments, the time domain resources indicated as downlink by the third indication information and as uplink by the fourth indication information belong to the first time domain resources, and / or the time domain resources not indicated as downlink or uplink by the third indication information (indicated as flexible time domain resources by the third indication information) and indicated as uplink by the fourth indication information belong to the second time domain resources.

[0144] The above schematically illustrates the first time domain resource and the second time domain resource. The first to fifth indication information are used as examples to configure and / or indicate the time domain resource. The present application is not limited thereto. The first to fifth indication information may also configure / indicate frequency domain resources. The present application is not limited thereto. Other configuration / indication information may also be used to indicate frequency domain resources.

[0145] In some embodiments, the information used to indicate the first frequency domain resource and / or the second frequency domain resource indicates the frequency domain position of the first frequency domain resource and / or the second frequency domain resource based on, for example, at least one reference subcarrier spacing (SCS) (for example, same as the SCS of the corresponding SCS-SpecificCarrier or BWP) and / or at least one reference RB (for example, a reference starting RB, which is, for example, the starting RB of the corresponding SCS-SpecificCarrier or CRB0 corresponding to the reference SCS). The information, for example, includes information indicating the offset between (the starting RB in) the first frequency domain resource and / or the second frequency domain resource relative to the reference RB and / or the number of RBs included in the first frequency domain resource and / or the second frequency domain resource.

[0146] For example, for the first frequency domain resource, when the indicated offset is 0, the starting RB in the first frequency domain resource is the reference RB, and the offset is 1. Similarly, the starting RB in the first frequency domain resource is the adjacent RB with a higher frequency domain position after the reference RB. For example, the SCS used / corresponding to the above RB is the above reference SCS.

[0147] The following describes the first frequency domain resource and the second frequency domain resource. In the first time domain, the first frequency domain resource is used for uplink and the second frequency domain resource is used for downlink. For example, the first frequency domain resource is an uplink subband (UL subband) in an SBFD time slot, and the second frequency domain resource is a downlink subband (DL subband) in an SBFD time slot. The following subband and frequency domain resource unit sets are interchangeable.

[0148] In some embodiments, the first frequency domain resources and the second frequency domain resources are in a time division duplex (TDD) band (or uppaired spectrum), or a downlink band of a frequency division duplex (FDD) band (paired spectrum), or an uplink band of an FDD band, or a supplementary uplink (SUL) band.

[0149] In some embodiments, there is a guard band between the first time domain resource and the second time domain resource, or there is no guard band between the first time domain resource and the second time domain resource.

[0150] In some embodiments, the first frequency domain resource is located on one side or in the middle of a carrier; there is a guard band between the first frequency domain resource and the second frequency domain resource, or there is no guard band between the first frequency domain resource and the second frequency domain resource.

[0151] Figure 3 is an example diagram of the first time domain resource and the second time domain resource according to an embodiment of the present application. As shown in Figure 3 , the first frequency domain resource (UL subband) in the first time domain resource is located in the middle of the carrier.

A guard band is provided between the first time domain resource and the second time domain resource, and a guard band is also provided between the first frequency domain resource and the second frequency domain resource.

[0153] Figure 5 is another example diagram of the first time domain resource and the second time domain resource in an embodiment of the present application. As shown in Figure 5, the first frequency domain resource (UL subband) in the first time domain resource is located in the middle of the carrier, and the second frequency domain resource (DL subband) is located on both sides of the carrier. There is a guard band between the first time domain resource and the second time domain resource, and there is no guard band between the first frequency domain resource and the second frequency domain resource.

[0154] Figure 6 is another example diagram of the first time domain resources and the second time domain resources according to an embodiment of the present application. As shown in Figure 6, the first frequency domain resource (UL subband) in the first time domain resources is located in the middle of the carrier, and the second frequency domain resource (DL subband) is located on both sides of the carrier. There is no guard band between the first time domain resource and the second time domain resource, but there is a guard band between the first frequency domain resource and the second frequency domain resource.

[0155] Figure 7 is another example diagram of the first time domain resources and the second time domain resources according to an embodiment of the present application. As shown in Figure 7, the first frequency domain resource (UL subband) in the first time domain resource is located in the middle of the carrier, and the second frequency domain resource (DL subband) is located on both sides of the carrier. A guard band is provided between the first time domain resource and the second time domain resource (DL symbol) preceding it, and a guard band is provided between the first frequency domain resource and the resource following it (flexible symbols that do not indicate DL or UL).

[0156] In some embodiments, the first frequency domain resources and / or the second frequency domain resources are cell-specifically configured, or the first frequency domain resources and / or the second frequency domain resources are BWP-specifically configured.

[0157] In some embodiments, the third frequency domain resource (uplink available resource) corresponding to the first time domain resource (determined and / or indicated as uplink by the aforementioned third indication information) can be used for the terminal device to send, and the fourth frequency domain resource (downlink available resource) corresponding to the first time domain resource (determined and / or indicated as downlink by the third indication information) can be used for the terminal device to receive;

[0158] The third frequency domain resource includes an intersection between an (activated) uplink BWP and the first frequency domain resource, or the third frequency domain resource includes a first frequency domain resource in an (activated) uplink BWP, or the third frequency domain resource includes an intersection between an (activated) uplink BWP and a first frequency domain resource in a downlink BWP associated with the uplink BWP.

[0159] The fourth frequency domain resources include the intersection between the (activated) downlink BWP and the second frequency domain resources, or the fourth frequency domain resources include the second frequency domain resources in the (activated) downlink BWP, or the fourth frequency domain resources include the intersection of the (activated) downlink BWP and the second frequency domain resources in the uplink BWP associated with the downlink BWP.

[0160] In some embodiments, the BWP identifiers of the associated uplink BWP and downlink BWP (must) be the same or (can) be different, the center frequencies (must) be the same or (can) be different, the SCSs (must) be the same or (can) be different, and the bandwidths (must) be the same or (can) be different.

[0161] In some embodiments, the SCS of the third frequency domain resource is the same as the uplink BWP (the size of the SCS) and / or belongs to the uplink BWP, and the SCS of the fourth frequency domain resource is the same as the downlink BWP (the size of the SCS) and / or belongs to the downlink BWP.

[0162] In some embodiments, the intersection between the uplink BWP and the first frequency domain resources or the intersection between the uplink BWP and the first frequency domain resources in the downlink BWP associated therewith includes: RBs in the uplink BWP that overlap with the first frequency domain resources, or RBs in the uplink BWP that completely overlap with the first frequency domain resources.

[0163] In some embodiments, the intersection between the downlink BWP and the second frequency domain resources or the intersection between the downlink BWP and the second frequency domain resources in the uplink BWP associated therewith includes: RBs in the downlink BWP that overlap with the second frequency domain resources, or RBs in the downlink BWP that completely overlap with the second frequency domain resources.

[0164] In some embodiments, the SCS of the first frequency domain resource is the same as (the size of) the uplink BWP, or the SCS of the first frequency domain resource is different from (the size of) the uplink BWP; the SCS of the second frequency domain resource is the same as (the size of) the downlink BWP, or the SCS of the second frequency domain resource is different from (the size of) the downlink BWP.

[0165] FIG8 is an example diagram of third and fourth frequency domain resources according to an embodiment of the present application. The third frequency domain resources may be referred to as uplink usable resources (UL usable RBs), and the fourth frequency domain resources may be referred to as downlink usable resources (DL usable RBs). As shown in FIG8 , taking a cell-specific SBFD subband as an example, the intersection of the UL subband and the activated uplink BWP is determined as the uplink usable resource, and the intersection of the DL subband and the activated downlink BWP is determined as the downlink usable resource.

[0166] Figure 9 is another example diagram of the third frequency domain resources and the fourth frequency domain resources of an embodiment of the present application. The third frequency domain resources can be referred to as uplink usable resources (UL usable RBs), and the fourth frequency domain resources can be referred to as downlink usable resources (DL usable RBs). As shown in Figure 9, taking the cell-specific SBFD subband as an example, different BWPs can be associated with different (or the same) cell-specific SBFD subband configurations. The intersection between the UL subband and the activated uplink BWP is determined as the uplink usable resource, and the intersection between the DL subband and the activated downlink BWP is determined as the downlink usable resource.

[0167] FIG10 is another example diagram of third and fourth frequency domain resources according to an embodiment of the present application. The third frequency domain resources may be referred to as uplink usable resources (UL usable RBs), and the fourth frequency domain resources may be referred to as downlink usable resources (DL usable RBs). As shown in FIG10 , taking the BWP-specific SBFD subband as an example, the intersection between the UL subband and the activated uplink BWP is determined as the uplink usable resource, and the intersection between the DL subband and the activated downlink BWP is determined as the downlink usable resource.

[0168] FIG11 is another example diagram of the third frequency domain resources and the fourth frequency domain resources of an embodiment of the present application. The third frequency domain resources may be referred to as uplink usable resources (UL usable RBs), and the fourth frequency domain resources may be referred to as downlink usable resources (DL usable RBs). As shown in FIG11 , taking the BWP-specific SBFD subband as an example, different BWPs may be associated with different (or the same) cell-specific SBFD subband configurations. The intersection between the UL subband and the activated uplink BWP is determined as the uplink usable resource, and the intersection between the DL subband and the activated downlink BWP is determined as the downlink usable resource.

[0169] Taking the first subband (UL subband) and the second subband (DL subband) as an example, they can be used to support SBFD operations (of network devices). From the perspective of the network device, the network device can receive (uplink) signals on the first subband and send (downlink) signals on the second subband in a time period. Thus, the possibility of sending and receiving signals at the same time is achieved (whether to receive and / or send depends on other configurations and / or scheduling). From the perspective of the terminal device, it can send (uplink) signals on the first subband or receive (downlink) signals on the second subband in this time period (whether to send / receive depends on other configurations and / or scheduling).

[0170] In some embodiments, the first subband and / or the second subband (their configuration) are for the same cell or within a cell, or in other words, the SBFD operation is for the same cell or within a cell. From the perspective of a network device, within the same cell, a (uplink) signal can be received on the first subband while a (downlink) signal is transmitted on the second subband during a time period. From the perspective of a terminal device, within the cell, a (uplink) signal can be transmitted on the first subband while a (downlink) signal is received on the second subband during the same time period.

[0171] In some embodiments, the third subband is, for example, a guard interval between the first subband and the second subband, and the first subband and / or the second subband and / or the third subband may include one or more continuous frequency domain resource units or multiple discontinuous frequency domain resource units, or the first subband and the second subband are composed of one or more continuous frequency domain resource units or multiple discontinuous frequency domain resource units. The frequency domain resource units include one or more of subcarriers, subcarrier sets / groups, RBs, RB sets / groups, etc. The number of subcarriers included in a subcarrier set is or is not a multiple of the number of subcarriers included in an RB, for example, the number of subcarriers included in a subcarrier group is less than the number of subcarriers included in one RB, but is not limited thereto. The RB group, for example, includes multiple RBs.

[0172] For example, if a frequency domain resource unit includes a subcarrier, a subcarrier group, an RB, or one of the RB groups, and the one is an RB, then the first subband includes one or more consecutive RBs or multiple discontinuous RBs. For another example, if a frequency domain resource unit includes a subcarrier and an RB, then the first subband may include an integer number of RBs and an integer number of subcarriers, and the integer number of RBs and the integer number of subcarriers may be consecutive or discontinuous.

[0173] In some embodiments, the number of frequency-domain resource units included in the first subband and / or the second subband is (must be) a multiple of N1 and / or a common multiple of N2, N3, and N4. For example, N1 = 2 or 4, N2 = 2, N3 = 3, N4 = 5, or other values, without limitation.

[0174] In some embodiments, the first subband may also be referred to as an uplink subband (UL subband), or an uplink SBFD subband, or an SBFD uplink subband, or an uplink RB set (i.e., an RB set for uplink), or an uplink SBFD RB set, or an SBFD uplink RB set. The embodiments of the present application are not limited to this.

[0175] In some embodiments, the second subband may also be referred to as a downlink subband (DL subband), or a downlink SBFD subband, or a SBFD downlink subband, or a downlink RB set (i.e., an RB set for downlink), or a downlink SBFD RB set, or a SBFD downlink RB set. The embodiments of the present application are not limited to this.

[0176] In some embodiments, there is a guard interval between the first subband (eg, UL subband) and the second subband (eg, DL subband), or there is no guard interval (GB) between the first subband (eg, UL subband) and the second subband (eg, DL subband).

[0177] The above schematically illustrates the relationship between the first time domain resources, the first frequency domain resources, and the second frequency domain resources. The following further illustrates the positions of the first frequency domain resources and the second frequency domain resources.

[0178] In some embodiments, the frequency domain positions of the first frequency domain resource and the second frequency domain resource are configured.The first frequency domain resource and the second frequency domain resource are cell-specific or cell common.

[0179] In some examples, the first frequency domain resources and the second frequency domain resources are configured per subcarrier spacing (SCS) (per SCS), or per SCS-specific carrier (per SCS-specificCarrier), or per carrier (per carrier).

[0180] For example, UL subbands and DL subbands are configured for different SCSs or different SCS-Specific Carriers or different carriers (with different SCSs). For example, the UL subbands and DL subbands configured for one SCS-Specific Carrier each include an integer number of RBs of the SCS that uses the SCS-Specific Carrier.

[0181] In some embodiments, the resource blocks (RBs) included in the first frequency domain resources or the second frequency domain resources that the terminal device expects to configure are within the SCS specific carrier, or the first frequency domain resources or the second frequency domain resources that the terminal device does not expect to configure include resource blocks (RBs) that are not within the SCS specific carrier.

[0182] Figure 12 is an example diagram of resource configuration according to an embodiment of the present application. As shown in Figure 12, the configured UL subband and DL subband are within the scope of the SCS-Specific Carrier. For example, the UE expects that all RBs included in the configured UL subband or DL ​​subband are within the SCS-Specific Carrier, and the UE does not expect that the configured UL subband or DL ​​subband includes RBs that are not within the SCS-Specific Carrier.

[0183] Figure 13 is another example diagram of resource configuration according to an embodiment of the present application. As shown in Figure 13, the configured UL subband and DL subband exceed the scope of the SCS-Specific Carrier. For example, the actual UL subband and / or DL ​​subband include portions of the UL subband and DL subband that overlap with the SCS-Specific Carrier, respectively.

[0184] In some embodiments, the first frequency domain resources and the second frequency domain resources are UE-specific and / or BWP-specific.

[0185] For example, the first frequency domain resources and the second frequency domain resources are configured per SCS, or per SCS-specific carrier, or per carrier. For example, the UL subband and DL subband configured for an SCS-SpecificCarrier each include an integer number of RBs of the SCS of the SCS-SpecificCarrier.

[0186] For another example, the first frequency domain resource and the second frequency domain resource are BWP-specific and are configured per BWP (per BWP), that is, UL subband and DL subband are configured respectively for different BWPs.

[0187] FIG14 is another example diagram of resource configuration according to an embodiment of the present application. As shown in FIG14 , for example, the UL subband and DL subband configured for a BWP each include an integer number of RBs of the SCS using the BWP.

[0188] The above examples illustrate resource configuration, but the present application is not limited thereto. For example, the above methods can be combined.

[0189] In some embodiments, the frequency domain position of the first frequency domain resource and the number of resource blocks (RBs) in the guard band are configured. The frequency domain position of the second frequency domain resource can be implicitly derived.

[0190] For example, the first frequency domain resources and the guard band are cell-specific, or the first frequency domain resources and the guard band are UE-specific and / or BWP-specific, or the first frequency domain resources and the guard band are cell-specific and / or UE-specific and / or BWP-specific.

[0191] FIG15 is another example diagram of resource configuration according to an embodiment of the present application. As shown in FIG15 , for example, the first frequency domain resource (UL subband) is cell-specific, and the guard band (GB) is UE-specific and / or BWP-specific.

[0192] The above schematically illustrates the frequency domain location of resources. The following will illustrate the time domain location of resources.

[0193] In some embodiments, the configuration period of the first frequency domain resources is the same as a pattern period (eg, TDD-UL-DL pattern period) or is an integer multiple of the pattern period (eg, TDD-UL-DL pattern period).

[0194] In some embodiments, the configuration period of the first time domain resource includes an integer number of pattern periods (eg, TDD-UL-DL pattern period) or an integer number of first time slot configuration periods or an integer number of second time slot configuration periods.

[0195] In some embodiments, different pattern periods (e.g., TDD-UL-DL pattern period) or different first time slot configuration periods corresponding to the same pattern (first pattern or second pattern) in the configuration period of the first time domain resource have the same configuration (SBFD resource configuration) for configuring the first time domain resource.

[0196] In some embodiments, different pattern periods (eg, TDD-UL-DL pattern period) corresponding to the same pattern or different first time slot configuration periods in the configuration period of the first time domain resources have different configurations (SBFD resource configurations) for configuring the first time domain resources.

[0197] In some embodiments, the pattern period (e.g., TDD-UL-DL pattern period) corresponding to different patterns (first pattern and second pattern) in the configuration period of the first time domain resource or the first time slot configuration period has an independent configuration (SBFD resource configuration) for configuring the first time domain resource.

[0198] The following first describes the case where one TDD-UL-DL pattern is configured (single-pattern).

[0199] Figure 16 is another example diagram of resource configuration according to an embodiment of the present application. As shown in Figure 16, patterns in different periods have the same SBFD configuration. For example, any two patterns (pattern 1) have the same SBFD configuration.

[0200] Figure 17 is another example diagram of resource configuration according to an embodiment of the present application. As shown in Figure 17, different patterns within a period have the same SBFD configuration. For example, any two patterns (pattern 1) may have different SBFD configurations.

[0201] Figure 18 is another example diagram of resource configuration according to an embodiment of the present application. As shown in Figure 18 , at least one pattern within a period has an SBFD configuration and at least one pattern does not. For example, within a period, there may be both patterns with and without SBFD.

[0202] Figure 19 is another example diagram of resource configuration according to an embodiment of the present application. As shown in Figure 19 , at least one pattern in a period has an SBFD configuration and at least one pattern does not have an SBFD configuration, and the SBFD configurations in the patterns with SBFD configurations are the same.

[0203] Figure 20 is another example diagram of resource configuration according to an embodiment of the present application. As shown in Figure 20 , there are patterns with different SBFD configurations within one cycle.

[0204] FIG21 is another example diagram of resource configuration according to an embodiment of the present application. As shown in FIG21 , at least one pattern in a period has an SBFD configuration and at least one pattern does not have an SBFD configuration, and the SBFD configurations of the patterns with SBFD configurations are at least partially different.

[0205] The following further describes the case where two TDD-UL-DL patterns are configured (two-patterns). For example, the case for single-pattern can be applied to two-patterns.

[0206] Figure 22 is another example diagram of resource configuration in an embodiment of the present application. As shown in Figure 22, the period of the first frequency domain resource is the same as the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the first pattern and the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the second pattern. For pattern1 and pattern2 respectively, any two patterns have the same SBFD configuration, that is, patterns in different periods have the same SBFD configuration. For example, only one of the patterns has an SBFD configuration.

[0207] Figure 23 is another example diagram of resource configuration according to an embodiment of the present application. As shown in Figure 23, the period of the first frequency domain resource is the same as the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the first pattern and the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the second pattern. For pattern 1 and pattern 2, any two patterns have the same SBFD configuration, that is, patterns in different periods have the same SBFD configuration. For example, two patterns each have an SBFD configuration.

[0208] FIG24 is another example diagram of resource configuration according to an embodiment of the present application. As shown in FIG24 , the period of the first frequency domain resource is an integer multiple of the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the first pattern and the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the second pattern. For example, only one of the patterns has an SBFD configuration.

[0209] Figure 25 is another example diagram of resource configuration of an embodiment of the present application. As shown in Figure 25, the period of the first frequency domain resource is an integer multiple of the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the first pattern and the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the second pattern. For example, the two patterns each have an SBFD configuration. For example, for different patterns, the number of pattern periods included in one period is the same; for another example, for different patterns, the number of pattern periods included in one period is different.

[0210] Figure 26 is another example diagram of resource configuration in an embodiment of the present application. As shown in Figure 26, the period of the first frequency domain resource is the sum of the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the first pattern and the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the second pattern (P=P1+P2). Within this period, SBFD configurations are provided for pattern1 and pattern2, respectively. For example, only one of the patterns has an SBFD configuration.

[0211] Figure 27 is another example diagram of resource configuration in an embodiment of the present application. As shown in Figure 27, the period of the first frequency domain resource is the sum of the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the first pattern and the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the second pattern (P = P1 + P2). Within this period, SBFD configurations are provided for pattern 1 and pattern 2, respectively. For example, two patterns each have an SBFD configuration.

[0212] Figure 28 is another example diagram of resource configuration according to an embodiment of the present application. As shown in Figure 28, the period of the first frequency domain resource is an integer multiple of the sum of the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the first pattern and the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) for the second pattern (P = P1 + P2). Within this period, SBFD configurations for pattern 1 and pattern 2 are provided respectively.

[0213] The above schematically illustrates the time domain configuration of resources, but the present application is not limited thereto. For example, the above embodiments may be combined. For example, single-pattern uses any of the embodiments shown in Figures 16 to 21, and two-patterns uses any of the embodiments shown in Figures 22 to 28, but the present application is not limited thereto.

[0214] The following is a schematic description of how to configure / determine the period.

[0215] In some embodiments, a configuration period of the first time domain resource is defined. The configuration period of the first time domain resource is the same as a pattern period (e.g., TDD-UL-DL pattern period) or a first time slot configuration period (e.g., slot configuration period P) or a second time slot configuration period (e.g., slot configuration period P2).

[0216] In some examples, when one pattern is configured, the configuration period of the first time domain resource is the same as the period of the one pattern or the same as the first time slot configuration period of the one pattern, and / or, when two patterns are configured, the configuration period of the first time domain resource is the same as the second time slot configuration period.

[0217] For example, for pattern 1, the configuration period of the first time domain resource is the same as the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) of pattern 1; for pattern 2, the configuration period of the first time domain resource is the same as the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) of pattern 2.

[0218] For another example, the configuration period of the first time domain resource is the same as the time slot configuration period.

[0219] For another example, the configuration period of the first time domain resource is the same as the TDD-UL-DL pattern period (of pattern 1, if only pattern 1 is configured); and is the same as the time slot configuration period (both are configured).

[0220] For another example, the configuration period of the first time domain resource is the same as N1 (of pattern 1, if only pattern 1 is configured) TDD uplink and downlink pattern periods (TDD-UL-DL pattern period) and / or the same as N2 time slot configuration periods (all configured). N1 and N2 are default values ​​greater than 1.

[0221] In some embodiments, the configuration period of the first time domain resource is configured, for example, as a cell-specific configuration or a UE-specific configuration.

[0222] In some examples, the configuration period of the first time domain resource is indicated by at least one of the following information:

[0223] the number of TDD uplink and downlink pattern periods (TDD-UL-DL pattern periods) or first time slot configuration periods (of the first pattern and / or the second pattern in the period);

[0224] the number of second slot configuration periods (in the period);

[0225] (In the said period) the number of TDD uplink and downlink pattern periods (TDD-UL-DL pattern period) or first time slot configuration periods for the first pattern, and / or the number of TDD uplink and downlink pattern periods (TDD-UL-DL pattern period) or first time slot configuration periods for the second pattern.

[0226] Taking the number of TDD uplink and downlink pattern periods (TDD-UL-DL pattern period) as an example, it can be applicable to pattern 1 (when only pattern 1 is configured) or to pattern 1 and pattern 2 (when both are configured).

[0227] For example, if the number is N, the SBFD subband configuration period is N time slot configuration periods, which includes N TDD-UL-DL pattern periods of pattern 1 (when only pattern 1 is configured), or includes N TDD-UL-DL pattern periods in pattern 1 and N TDD-UL-DL pattern periods in pattern 2 (when both pattern 1 and pattern 2 are configured).

[0228] For another example, when the information of the number does not exist / is provided in the IE / field / message (RRC) used to configure the time domain position of the SBFD subband or SBFD symbol, the number is a default value, for example, the default value is 1.

[0229] For another example, regarding the numerical range of the number, in one example, the number can be indicated as 1, such as the candidate values ​​{1, 2, 4, 8}; this information is mandatory in the IE / field / message (RRC) used to configure the time-domain position of the SBFD subband or SBFD symbol. In another example, the number cannot be indicated as 1, such as the candidate values ​​{2, 4, 8}; this information is optional in the IE / field / message (RRC) used to configure the time-domain position of the SBFD subband or SBFD symbol. If it does not exist / is not provided, the default value is 1.

[0230] Take the number of slot configuration periods as an example.

[0231] For example, if the number is N, the SBFD subband configuration period is N time slot configuration periods. When this information is not present / provided in the IE / field / message (RRC) for configuring the time domain position of the SBFD subband or SBFD symbol, the number is a default value, for example, a default value of 1.

[0232] For another example, regarding the numerical range of the number, in one example, the number can be indicated as 1, such as the candidate values ​​{1, 2, 4, 8}; this information is mandatory in the IE / field / message (RRC) used to configure the time-domain position of the SBFD subband or SBFD symbol. In another example, the number cannot be indicated as 1, such as the candidate values ​​{2, 4, 8}; this information is optional in the IE / field / message (RRC) used to configure the time-domain position of the SBFD subband or SBFD symbol. If it does not exist / is not provided, the default value is 1.

[0233] Take the number of TDD uplink and downlink pattern periods (TDD-UL-DL pattern period) for the first pattern and / or the number of TDD uplink and downlink pattern periods (TDD-UL-DL pattern period) for the second pattern as an example.

[0234] For example, if the number for pattern 1 is N1 and the number for pattern 2 is N2, the SBFD subband configuration period is the largest slot configuration period among (N1, N2). In the SBFD subband configuration period, there are N1 or a maximum of N1 TDD-UL-DL pattern periods for pattern 1 and N2 or a maximum of N2 TDD-UL-DL pattern periods for pattern 2, each including SBFD symbols.

[0235] For another example, for pattern 1, if the number is N1, the SBFD subband configuration period of pattern 1 is N1 TDD-UL-DL pattern periods of pattern 1; for pattern 2, if the number is N2, the SBFD subband configuration period of pattern 2 is N2 TDD-UL-DL pattern periods of pattern 2.

[0236] For another example, the information in the IE / field / message (RRC) for configuring the time-domain position of the SBFD subband or SBFD symbol (for pattern 1 and / or pattern 2) is optional (for each pattern, pattern 1 or pattern 2). For pattern 1 / pattern 2, when this information is not present / provided in the IE / field / message (RRC) for configuring the time-domain position of the SBFD subband or SBFD symbol, the number is a default value, for example, a default value of 0.

[0237] For another example, regarding the numerical range of this number, in one example, for pattern 1 / pattern 2, the number can be indicated as 0, such as the candidate values ​​{0, 1, 2, 4}; this information is mandatory in the IE / field / message (RRC) used to configure the time-domain position of the SBFD subband or SBFD symbol. In another example, for pattern 1 / pattern 2, the number cannot be indicated as 0, such as the candidate values ​​{1, 2, 4}; this information is optional in the IE / field / message (RRC) used to configure the time-domain position of the SBFD subband or SBFD symbol. If it is not present / not provided, the default value is 0.

[0238] The above schematically illustrates how to configure / determine a period. The present application is not limited thereto. For example, the various embodiments described above may be combined. The following further illustrates how to configure / determine whether a pattern period (e.g., a TDD UL-DL pattern period) within a period includes first time domain resources (e.g., SBFD symbols).

[0239] In some embodiments, at least one pattern period (TDD-UL-DL pattern period) corresponding to at least one pattern in the configuration period of the first time domain resource or the first time slot configuration period is configured to include (or is configured with) the first time domain resource, or at least one second time slot configuration period in the configuration period of the first time domain resource includes (or is configured with) the first time domain resource.

[0240] In some embodiments, a pattern having a first time domain resource configuration and / or a configuration period of a first time domain resource and / or a pattern period including a first time domain resource (TDD-UL-DL pattern period) and / or a first time slot configuration period and / or a second time slot configuration period is defined or indicated.

[0241] In some embodiments, a pattern period (TDD-UL-DL pattern period) that does not have a first time domain resource configuration and / or a configuration period of the first time domain resource that does not include a pattern period of the first time domain resource and / or a first time slot configuration period and / or a second time slot configuration period is defined or indicated.

[0242] In some examples, whether the first time domain resource is included in a TDD uplink and downlink pattern period (TDD-UL-DL pattern period) is defined.

[0243] For example, one or more specific TDD UL-DL pattern periods of pattern 1 and / or one or more specific TDD-UL-DL pattern periods of pattern 2 in the SBFD subband configuration period include SBFD symbols.

[0244] For another example, one or more specific time slot configuration periods in the SBFD subband configuration period include SBFD symbols. In a specific time slot configuration period, the TDD-UL-DL pattern period of pattern 2 in one or more specific time slot configuration periods in the SBFD subband configuration period includes SBFD symbols.

[0245] For another example, in one or more specific time slot configuration periods in the SBFD subband configuration period, the TDD-UL-DL pattern period of pattern 1 and / or the TDD-UL-DL pattern period of pattern 2 include SBFD symbols.

[0246] In some embodiments, the configuration period of the first time domain resources includes a pattern period (TDD-UL-DL pattern period) of the first time domain resources or a first time slot configuration period, and / or the configuration period of the first time domain resources does not include a pattern period (TDD-UL-DL pattern period) of the first time domain resources or a first time slot configuration period, which is indicated by at least one of the following information:

[0247] A bitmap corresponding to a pattern period (TDD-UL-DL pattern period) or a first time slot configuration period;

[0248] An index of a TDD-UL-DL pattern period, a first slot configuration period, or a second slot configuration period;

[0249] Including the start and / or end of the pattern period (TDD-UL-DL pattern period) of the first time domain resource or the first time slot configuration period or the second time slot configuration period (slot configuration period);

[0250] Including the number of pattern periods (TDD-UL-DL pattern periods) of the first time domain resources or the first time slot configuration period or the second time slot configuration period (slot configuration period);

[0251] It does not include the pattern period (TDD-UL-DL pattern period) of the first time domain resource or the first time slot configuration period or the number of time slot configuration periods (slot configuration period).

[0252] Take the bitmap corresponding to the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) as an example.

[0253] For example, one bit in the bitmap corresponds to one or more TDD-UL-DL pattern periods of pattern 1 and / or one or more TDD-UL-DL pattern periods of pattern 2. For example, if one bit in the bitmap is 1, the corresponding TDD-UL-DL pattern period of pattern 1 and / or the corresponding TDD-UL-DL pattern period of pattern 2 includes an SBFD symbol, and otherwise does not include it. Vice versa.

[0254] For another example, a bit in the bitmap corresponds to one or more time slot configuration periods. For example, if a bit in the bitmap is 1, then both the TDD-UL-DL pattern period of pattern 1 and the TDD-UL-DL pattern period of pattern 2 in the corresponding time slot configuration field include SBFD symbols, otherwise, they do not. Vice versa.

[0255] For another example, the number of bits in the bitmap (assuming one-to-one mapping) may be the same as the maximum number of time slot configuration periods in the SBFD subband configuration period, or may be the same as the maximum number of TDD-UL-DL pattern periods of pattern 1 and / or pattern 2 in the SBFD subband configuration period.

[0256] For example, the number of valid bits in the bitmap (assuming one-to-one mapping) is the same as the number of time slot configuration periods in the SBFD subband configuration period, or the same as the number of TDD-UL-DL pattern periods of pattern 1 and / or pattern 2 in the SBFD subband configuration period.

[0257] For another example, when both pattern 1 and pattern 2 are configured, the bitmap is applied to one or both of pattern 1 and pattern 2. That is, the bitmap may be common to pattern 1 and pattern 2, or may be specifically applicable to only pattern 1 or pattern 2. In the latter case, pattern 1 and pattern 2 have different bitmaps, e.g., bitmap 1 for pattern 1 and bitmap 2 for pattern 2.

[0258] Take the index of a TDD uplink and downlink pattern period (TDD-UL-DL pattern period) or a slot configuration period (slot configuration period) as an example.

[0259] For example, it may be the index of the TDD UL-DL pattern period in the SBFD subband configuration period. For example, if the index is indicated, the corresponding TDD-UL-DL pattern period of pattern 1 and / or the corresponding TDD-UL-DL pattern period of pattern 2 includes SBFD symbols, otherwise, the SBFD symbols are not included. Vice versa.

[0260] For another example, it may be a time slot configuration period index in an SBFD subband configuration period. For example, if an index is indicated, the TDD-UL-DL pattern period of pattern 1 and / or the TDD-UL-DL pattern period of pattern 2 in the corresponding time slot configuration period include SBFD symbols; otherwise, SBFD symbols are not included. Vice versa.

[0261] Taking the start and / or end of the TDD uplink and downlink pattern period (TDD-UL-DL pattern period) or slot configuration period (slot configuration period) including the first time domain resource as an example. For example, the start / first and / or end / last TDD-UL-DL pattern period (pattern 1 and / or pattern 2) includes an SBFD sybmol.

[0262] Taking the number of the TDD-UL-DL pattern periods or slot configuration periods including the first time domain resource as an example, for example, the start / first and / or end / last slot configuration period includes SBFD sybmols.

[0263] Take the number of the TDD uplink and downlink pattern periods (TDD-UL-DL pattern period) or time slot configuration period (slot configuration period) that does not include the first time domain resource as an example. For example, the number of TDD-UL-DL pattern periods of pattern 1 and / or pattern 2 does not include SBFD sybmol, or the number of time slot configuration periods (slot configuration period) does not include SBFD sybmol.

[0264] The above schematically illustrates whether the period includes the first time domain resource. The present application is not limited thereto. For example, various combinations of the above embodiments may be performed. The following further illustrates how to configure / determine whether there is a corresponding first time domain resource configuration when Pattern 1 and Pattern 2 are configured.

[0265] In some embodiments, whether the first pattern and / or the second pattern corresponds to the configuration of the first time domain resource is indicated by the TDD uplink and downlink configuration or the first configuration.

[0266] In some examples, cell-specific configuration is used as an example.

[0267] For example, the TDD-UL-DL-ConfigCommon IE includes information (called SBFD (time domain) resource configuration or information for configuring SBFD symbols in a TDD-UL-DL pattern period) and / or information for (called information for indicating a period) and / or the aforementioned information. Thus, the TDD-UL-DL-ConfigCommon IE of pattern1 and pattern2 can respectively (optionally) provide / indicate (for / correspond to) the SBFD time domain resources (SBFD slots and / or symbols) and / or periods of pattern1 and pattern2. At this time, the TDD-UL-DL-ConfigCommon IE can be regarded as an (RRC) IE used to configure time location of SBFD subbands or SBFD symbols. There is no need to configure / determine whether pattern1 and pattern2 have corresponding SBFD time domain resource configurations through additional information.

[0268] In some examples, Cell-specific / UE-specific configuration is taken as an example.

[0269] For example, the above information may be included in other messages / IEs besides the TDD-UL-DL-ConfigCommon IE. How to provide / indicate (for / correspond to) SBFD time domain resources (SBFD slots and / or symbols) for pattern 1 and pattern 2 may be referred to the following embodiments.

[0270] In some embodiments, one or two SBFD resource configurations may be provided, and one SBFD resource configuration corresponds to one or both of pattern 1 and pattern 2. For example, when one SBFD resource configuration is provided, one SBFD resource configuration corresponds to one or both of pattern 1 and pattern 2; when two SBFD resource configurations are provided, the two SBFD resource configurations correspond to pattern 1 and pattern 2, respectively. One SBFD resource configuration, for example, provides the position of the SBFD (time domain) resource (symbol / slot) included in the TDD-UL-DL pattern period of the corresponding pattern 1 or pattern 2, and applies to all TDD-UL-DL pattern periods including SBFD symbols of the corresponding pattern 1 or pattern 2 included in one / each SBFD subbands configuration period.

[0271] For example, the SBFD resource configurations corresponding to pattern 1 and pattern 2 are indicated using the same information field. For example, when only one SBFD resource configuration is provided, it corresponds to pattern 1 or pattern 2 by default. When two SBFD resource configurations are provided, they correspond to pattern 1 and pattern 2, sequentially according to the configuration order. For another example, the information field or SBFD resource configuration includes information indicating that the SBFD resource configuration corresponds to pattern 1 and / or pattern 2. For another example, the above examples can be combined.

[0272] For example, when only one SBFD resource configuration and / or only pattern 1 is provided, the above information is not provided or is provided as an option, or is absent or optional (i.e., it may or may not be present). For example, when this information is not provided, the SBFD resource configuration corresponds to pattern 1 by default. When two SBFD resource configurations and / or both pattern 1 and pattern 2 are provided, this information is required or must be present.

[0273] For another example, the SBFD resource configurations corresponding to pattern 1 and pattern 2 are indicated through different information fields.

[0274] In some embodiments, one or two groups of SBFD resource configurations may be provided, and one group of SBFD resource configurations corresponds to one or two of pattern 1 and pattern 2. For example, when one group of SBFD resource configurations is provided, one group of SBFD resource configurations corresponds to one or two of pattern 1 and pattern 2; when two groups of SBFD resource configurations are provided, the two groups of SBFD resource configurations correspond to pattern 1 and pattern 2, respectively. A group of SBFD resource configurations includes one or more SBFD resource configurations. One SBFD resource configuration, for example, provides the position of an SBFD (time domain) resource (symbol / slot) included in a TDD-UL-DL pattern period. One SBFD resource configuration in one group of SBFD resource configurations is applied to one or more TDD-UL-DL pattern periods including SBFD symbols of corresponding pattern 1 or pattern 2 included in a period. Different SBFD resource configurations in one group of SBFD resource configurations are applied to different TDD-UL-DL pattern periods including SBFD symbols in the period.

[0275] For example, the same information field indicates a set of SBFD resource configurations corresponding to pattern 1 and pattern 2. For example, when only one set of SBFD resource configurations is provided, the default is pattern 1 or pattern 2. When two sets of SBFD resource configurations are provided, pattern 1 and pattern 2 are corresponding in the order in which they are configured. For another example, the information field or SBFD resource configuration includes information indicating that the SBFD resource configuration corresponds to pattern 1 and / or pattern 2. For another example, the above examples can be combined.

[0276] For example, when only one SBFD resource configuration set and / or only pattern 1 is provided, the above information is not provided or is provided as an option, or is absent or optional (i.e., it may or may not be present). For example, when this information is not provided, the SBFD resource configuration set corresponds to pattern 1 by default. When two SBFD resource configuration sets and / or both pattern 1 and pattern 2 are provided, this information is required or must be present.

[0277] For another example, the SBFD resource configurations corresponding to pattern 1 and pattern 2 are indicated through different information fields.

[0278] In some implementations, it is also possible to consider how to release the SBFD resource configuration for pattern 1 and / or pattern 2. For example, the SBFD resource configuration has an identifier for indicating information on releasing the SBFD resource configuration, and the identifier indicating the SBFD resource configuration indicates that the corresponding SBFD resource configuration is released.

[0279] The following further describes how to configure / determine the position of the first time domain resource included in a pattern in a period.

[0280] In some embodiments, the first time domain resource in a pattern period or a first time slot configuration period is indicated by at least one of the following information, or the configuration for the first time domain resource (first configuration, such as an SBFD configuration) may include at least one of the following information:

[0281] A starting time slot including the first time domain resource and a starting symbol of the first time domain resource in the starting time slot; an ending time slot including the first time domain resource and an ending symbol of the first time domain resource in the ending time slot;

[0282] The starting time slot of the first time domain resource, the starting symbol of the first time domain resource in the starting time slot, and the number of symbols of the first time domain resource;

[0283] The end slot of the first time domain resource, the end symbol of the first time domain resource in the end slot, and the number of symbols of the first time domain resource;

[0284] a starting symbol of the first time domain resource, and the number of symbols of the first time domain resource;

[0285] The end symbol of the first time domain resource, and the number of symbols of the first time domain resource;

[0286] The starting symbol of the first time domain resource and the ending symbol of the first time domain resource.

[0287] In some examples, information associated with a time slot and information associated with a time slot symbol may be configured or indicated to be arranged in positive order on a timeline.

[0288] Figure 29 is an example diagram of determining the location of the first time domain resource according to an embodiment of the present application. As shown in Figure 29, for example, information such as slot offset = 1, symbol offset = 9, number of slots = 3, and number of symbols = 9 can be configured or indicated to determine the location of the first time domain resource.

[0289] Figure 30 is another example diagram of determining the location of the first time domain resource according to an embodiment of the present application. As shown in Figure 30 , for example, information such as slot offset = 2, symbol offset = 5, number of slots = 1, and number of symbols = 9 can be configured or indicated to determine the location of the first time domain resource.

[0290] The following is a schematic description of various configuration information.

[0291] In some implementations, a starting time slot of the first time domain resource may be configured or indicated.

[0292] In some examples, the starting / first slot (of slots) including SBFD symbols is taken as an example.

[0293] For example, the first configuration may include: (1) the slot offset from the starting / first slot (of slots) including SBFD symbols to (2) the first slot in a TDD-UL-DL pattern period, or, the slot offset from the first slot in a TDD-UL-DL pattern period to the starting / first slot (of slots) including SBFD symbols, or, the slot offset between the first slot in a TDD-UL-DL pattern period and the starting / first slot (of slots) including SBFD symbols.

[0294] For example, when the slot offset is 0 or 1, the starting / first slot (of slots) including SBFD symbols is the first slot in the cycle (corresponding to slot index 0 or 1); when the slot offset is 1 or 2, the starting / first slot (of slots) including SBFD symbols is the second slot in the cycle (corresponding to slot index 1 or 2), and so on.

[0295] For example, the first configuration may include a slot index of a starting / first slot (of slots) including SBFD symbols. For example, when the slot index is 0 or 1, the starting / first slot (of slots) including SBFD symbols is the first slot in the cycle; when the slot index is 1 or 2, the starting / first slot (of slots) including SBFD symbols is the second slot in the cycle, and so on.

[0296] In some examples, taking the number of slots not including SBFD symbols (or including only non-SBFD symbols, or including all non-SBFD symbols) as an example, the count starts from the first slot in the TDD-UL-DL pattern period to the last slot in the period not including SBFD symbols.

[0297] For example, the first configuration may include the number of slots not including SBFD symbols. For example, when the number of slots is 0, the starting / first slot (of slots) including SBFD symbols is the first slot in the cycle; when the number of slots is 1, the starting / first slot (of slots) including SBFD symbols is the second slot in the cycle, and so on.

[0298] In some examples, taking n slots not including full SBFD symbols (or including all non-SBFD symbols, or including both SBFD symbols and non-SBFD symbols) as an example, the count starts from the first slot in the TDD-UL-DL pattern period to the last slot not including all SBFD symbols.

[0299] For example, the first configuration may include: the number of slots not including full SBFD symbols. For example, when the number of slots is 0, the starting / first slot (of slots) including SBFD symbols is the first slot in the cycle and the starting / first SBFD symbol is the first symbol of the first slot (in this case, relevant information about the starting / first SBFD symbol may not be required); when the number of slots is 1, the starting / first slot (of slots) including SBFD symbols is the second slot in the cycle, and so on.

[0300] In some implementations, a starting symbol of the first time domain resource in a starting time slot may be configured or indicated.

[0301] In some examples, a starting / first SBFD symbol in the starting slot is taken as an example.

[0302] For example, the first configuration may include: the symbol offset from (4) the first symbol in the starting slot to (3) the starting / first SBFD symbol in the starting slot, or the symbol offset from the starting / first SBFD symbol in the starting slot to the first symbol in the starting slot, or the symbol offset between the starting / first SBFD symbol in the starting slot and the first symbol in the starting slot.

[0303] For example, when the symbol offset is 0 or 1, the starting / first SBFD symbol in the starting slot is the first symbol in the starting slot (corresponding to symbol index 0 or 1); when the symbol offset is 1 or 2, the starting / first SBFD symbol in the starting slot is the second symbol in the starting slot (corresponding to symbol index 1 or 2), and so on.

[0304] For example, the first configuration may include a symbol index of a starting / first SBFD symbol in the starting slot. For example, when the symbol index is 0 or 1, the starting / first SBFD symbol in the starting slot is the first symbol in the starting slot; when the symbol index is 1 or 2, the starting / first SBFD symbol in the starting slot is the second symbol in the starting slot, and so on.

[0305] In some examples, taking the number of SBFD symbols in the starting slot as an example, the counting starts from the first SBFD symbol in the starting slot to the last (SBFD) symbol in the starting slot.

[0306] For example, the first configuration may include the number of SBFD symbols in the starting slot. For example, when the number of symbols is 1, the starting / first SBFD symbol is the last symbol in the starting slot. When the number of symbols is 2, the starting / first SBFD symbol is the second-to-last symbol in the starting slot, and so on.

[0307] In some examples, taking the number of non-SBFD symbols in the starting slot (not including full SBFD symbols) as an example, the counting starts from the first (non-SBFD) symbol in the starting slot to the last non-SBFD symbol in the starting slot.

[0308] For example, the first configuration may include the number of slots not including full SBFD symbols. For example, when the number of symbols is 0, the starting / first SBFD symbol is the first symbol in the starting slot. When the number of symbols is 1, the starting / first SBFD symbol is the second symbol in the starting slot, and so on.

[0309] In some implementations, the end slot of the first time domain resource may be configured or indicated.

[0310] In some examples, an ending slot (of slots) including SBFD symbols is taken as an example.

[0311] For example, the first configuration may include: (5) a slot offset from the ending slot (of slots) including SBFD symbols to the first slot in a TDD-UL-DL pattern period, or a slot offset from the first slot in a TDD-UL-DL pattern period to the ending slot (of slots) including SBFD symbols, or a slot offset between the first slot in a TDD-UL-DL pattern period and the ending slot (of slots) including SBFD symbols.

[0312] For example, when the slot offset is 0 or 1, the ending slot (of slots) including SBFD symbols is the first slot in the cycle (corresponding to slot index 0 or 1); when the slot offset is 1 or 2, the ending slot (of slots) including SBFD symbols is the second slot in the cycle (corresponding to slot index 1 or 2), and so on.

[0313] For example, the first configuration may include: (5) a slot index of an ending slot (of slots) including SBFD symbols. For example, when the slot index is 0 or 1, the ending slot (of slots) including SBFD symbols is the first slot in the cycle; when the slot index is 1 or 2, the ending slot (of slots) including SBFD symbols is the second slot in the cycle, and so on.

[0314] For example, the first configuration may include: (5) the slot offset from the ending slot (of slots) including SBFD symbols to the starting / first slot (of slots) including SBFD symbols, or the slot offset from the starting / first slot (of slots) including SBFD symbols to the ending slot (of slots) including SBFD symbols, or the slot offset between the starting / first slot (of slots) including SBFD symbols and the ending slot (of slots) including SBFD symbols.

[0315] For example, the first configuration may include: a slot offset from the ending slot (of slots) including SBFD symbols to (7) the first slot including full SBFD symbols, or a slot offset from the first slot including full SBFD symbols to the ending slot (of slots) including SBFD symbols, or a slot offset between the first slot including full SBFD symbols and the ending slot (of slots) including SBFD symbols.

[0316] In some examples, the number of slots including SBFD symbols is taken as an example, for example, counting between the start slot and / or the end slot including the SBFD symbols.

[0317] In some examples, the first configuration may include the number of slots including SBFD symbols except the starting slot and / or the last slot that includes SBFD symbols as an example.

[0318] In some examples, the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols is taken as an example.

[0319] For example, the first configuration may include: a time slot offset from (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols to (2) the first slot in a TDD-UL-DL pattern period, or a time slot offset from (2) the first slot in a TDD-UL-DL pattern period to (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols, or a time slot offset between (2) the first slot in a TDD-UL-DL pattern period and (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols.

[0320] For example, if the time slot offset is 0 or 1, then (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols is the first time slot of the cycle (corresponding to time slot index 0 or 1); if the time slot offset is 1 or 2, then (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols is the second time slot of the cycle (corresponding to time slot index 1 or 2); and so on.

[0321] For example, the first configuration may include: (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols, a time slot index. For example, if the time slot index is 0 or 1, then (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols is the first time slot of the cycle; if the time slot index is 1 or 2, then (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols is the second time slot of the cycle; and so on.

[0322] For another example, the first configuration may include: a time slot offset from (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols to (1) starting / first slot (of slots) including SBFD symbols, or a time slot offset from (1) starting / first slot (of slots) including SBFD symbols to (8), or a time slot offset between (1) starting / first slot (of slots) including SBFD symbols and (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols.

[0323] For another example, the first configuration may include: a time slot offset from (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols to (7) the first slot including full SBFD symbols, or a time slot offset from (7) the first slot including full SBFD symbols to (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols, or a time slot offset between (7) the first slot including full SBFD symbols and (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols.

[0324] For another example, the first configuration may include: a time slot offset from (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols to (5) the ending slot (of slots) including SBFD symbols, or a time slot offset from (5) the ending slot (of slots) including SBFD symbols to (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols, or a time slot offset between (5) the ending slot (of slots) including SBFD symbols and (8) the first slot of slots not including SBFD symbols after configured SBFD symbols or slots including SBFD symbols.

[0325] In some implementations, the end / last symbol of the first time domain resource in the end slot may be configured or indicated.

[0326] In some examples, the ending / last symbol of SBFD symbols in the ending slot is taken as an example.

[0327] For example, the first configuration may include: a symbol offset from (10) the first symbol in the ending slot to (9) the ending / last symbol of SBFD symbols in the ending slot, or a symbol offset from (9) to (10), or a symbol offset between (9) the ending / last symbol of SBFD symbols in the ending slot and (10) the first symbol in the ending slot.

[0328] For example, when the symbol offset is 0 or 1, (9) the ending / last symbol of SBFD symbols in the ending slot is the first symbol in the ending slot (corresponding to symbol index 0 or 1); when the symbol offset is 1 or 2, (9) the ending / last symbol of SBFD symbols in the ending slot is the second symbol in the ending slot (corresponding to symbol index 1 or 2), and so on.

[0329] For example, the first configuration may include: (9) the ending / last symbol of SBFD symbols in the ending slot. For example, when the symbol index is 0 or 1, (9) the ending / last symbol of SBFD symbols in the ending slot is the first symbol of the ending slot; when the sequence index is 1 or 2, (9) the ending / last symbol of SBFD symbols in the ending slot is the second symbol in the starting slot, and so on.

[0330] In some examples, taking the number of SBFD symbols in the ending slot as an example, the counting starts from the first SBFD symbol in the ending slot to the last (SBFD) symbol in the ending slot.

[0331] In some examples, taking the number of non-SBFD symbols in the ending slot as an example, the counting starts from the first non-SBFD symbol in the ending slot to the last non-SBFD symbol in the ending slot.

[0332] In some examples, information related to time slots and information related to time slot symbols may be configured or indicated to be arranged in opposite order of the timeline.

[0333] Figure 31 is an example diagram of determining the location of a first time domain resource according to an embodiment of the present application. As shown in Figure 31 , for example, information such as slot offset = 1 / -1, number of slots = 3, number of symbols = 9, and number of symbols = 5 can be configured or indicated to determine the location of the first time domain resource.

[0334] In some examples, information associated with a symbol may be configured or indicated to be arranged in positive order of a timeline.

[0335] For example, the first configuration may include: (11) starting / first SBFD symbol in a TDD-UL-DL pattern period. In an example, for example, a symbol offset from (11) starting / first SBFD symbol in a TDD-UL-DL pattern period to (12) the first symbol in a TDD-UL-DL pattern period, or a symbol offset from (12) the first symbol in a TDD-UL-DL pattern period to (11) starting / first SBFD symbol in a TDD-UL-DL pattern period, or a symbol offset between (12) the first symbol in a TDD-UL-DL pattern period and (11) starting / first SBFD symbol in a TDD-UL-DL pattern period. In another example, for example, the symbol index of (11) starting / first SBFD symbol in a TDD-UL-DL pattern period in the period; for example, if the symbol index is 0 or 1, then (11) is the first symbol of the period; if the symbol index is 1 or 2, then (11) starting / first SBFD symbol in a TDD-UL-DL pattern period is the second symbol of the period, and so on.

[0336] For another example, the first configuration may include: information for configuring the number of SBFD symbols in a TDD-UL-DL pattern period.

[0337] In some examples, information associated with a symbol may be configured or indicated to be arranged in the opposite order of the timeline.

[0338] For example, the first configuration may include: (13)ending / last SBFD symbol in a TDD-UL-DL pattern period. In an example, for example, a symbol offset from (13)ending / last SBFD symbol in a TDD-UL-DL pattern period to (14)the first UL symbol in a TDD-UL-DL pattern period, or a symbol offset from (14)the first UL symbol in a TDD-UL-DL pattern period to (13)ending / last SBFD symbol in a TDD-UL-DL pattern period, or a symbol offset between (14)the first UL symbol in a TDD-UL-DL pattern period and (13)ending / last SBFD symbol in a TDD-UL-DL pattern period. In another example, for example, the symbol index of the (13)ending / last SBFD symbol in a TDD-UL-DL pattern period in the period; for example, if the symbol index is 0 or 1, then the (13)ending / last SBFD symbol in a TDD-UL-DL pattern period is the first symbol of the period; if the symbol index is 1 or 2, then the (13)ending / last SBFD symbol in a TDD-UL-DL pattern period is the second symbol of the period, and so on.

[0339] For another example, the first configuration may include: information for configuring the number of SBFD symbols in a TDD-UL-DL pattern period.

[0340] The above schematically illustrates how to determine the position of the first time domain resource, but the present application is not limited thereto. For example, various combinations of the above implementations may be performed.

[0341] In some embodiments,

[0342] If the symbols in the SBFD resource are indicated as uplink by the TDD uplink and downlink configuration, the symbols are non-SBFD resources; or

[0343] The symbol indicated as uplink by the TDD uplink / downlink configuration is configured as an SBFD resource, then the symbol is a non-SBFD resource; or

[0344] Symbols indicated as uplink by the TDD uplink / downlink configuration are not expected to be configured as SBFD resources; or

[0345] The TDD uplink and downlink configuration indicates that the symbols in the SBFD resources are uplink symbols or downlink symbols instead of flexible symbols; or

[0346] For cells configured with SBFD configuration, the terminal device does not expect to be provided with TDD uplink and downlink configuration.

[0347] In some embodiments,

[0348] DCI format 2_0 is used to indicate SBFD resources and uplink and downlink of flexible symbols; or

[0349] DCI format 2_0 is used to indicate uplink and downlink of flexible symbols; or

[0350] DCI format 2_0 is used to indicate the uplink and downlink of flexible symbols of non-SBFD resources; or

[0351] For cells configured with SBFD, the terminal device is not expected to be configured to monitor DCI format 2_0; or

[0352] For cells configured with SBFD configuration, terminal devices are not expected to be configured to monitor DCI format 2_0 with slot format indication (SFI).

[0353] The information used to indicate the link direction of the first time domain resource is further described below.

[0354] In some embodiments, the information for indicating the link direction of the first time domain resource indicates the link direction of the first time domain resource and / or the second time domain resource based on one of the following periods:

[0355] A configuration period of the first time domain resource;

[0356] a pattern period (TDD-UL-DL pattern period) or a first time slot configuration period;

[0357] Second time slot configuration period.

[0358] In some embodiments, the information used to indicate the link direction of the first time domain resource is (only) used to indicate the link direction of the first time domain resource configured in the downlink resource.

[0359] In some embodiments, the terminal device receives TDD uplink and downlink dedicated configuration information, where the TDD uplink and downlink dedicated configuration information indicates a link direction of the first time domain resource and / or the second time domain resource based on one of the following periods:

[0360] A configuration period of the first time domain resource;

[0361] a pattern period (TDD-UL-DL pattern period) or a first time slot configuration period;

[0362] Second time slot configuration period.

[0363] For example, the TDD uplink and downlink dedicated configuration information is only used to indicate the link direction (eg, DL, UL) of the flexible time domain resources that are not configured with the first time domain resources.

[0364] For example, the TDD uplink and downlink dedicated configuration information is used to indicate the link direction of flexible time domain resources that are not configured with the first time domain resources (or do not correspond to the first time domain resources and do not overlap with the first time domain resources) and flexible time domain resources that are configured with the first time domain resources (or do not correspond to the first time domain resources and do not overlap with the first time domain resources).

[0365] In some embodiments, an uplink signal or channel is sent or a downlink signal or channel is received in the first time domain resource, wherein the frequency domain resource used to send the uplink signal or channel belongs to a third frequency domain resource, and / or the frequency domain resource used to receive the downlink signal or channel belongs to a fourth frequency domain resource;

[0366] The uplink signal or channel includes SRS, PUCCH, PUSCH or PRACH, and the downlink signal or channel includes PDCCH, PDSCH, CSI-RS or DL ​​PRS.

[0367] In some embodiments, if an uplink signal or channel is configured or scheduled to be sent and the frequency domain resources corresponding to the uplink signal or channel include resources that do not belong to the first frequency domain resources or the third frequency domain resources, the uplink signal or channel is not sent, and / or, if a downlink signal or channel is configured to be received and the downlink signal or channel includes resources that do not belong to the second frequency domain resources or the fourth frequency domain resources, the downlink signal or channel is not received.

[0368] In some embodiments, when information is provided for indicating the link direction of the first time domain resource, an uplink signal or channel is no longer sent on the first time domain resource indicated as downlink by the information, and / or a downlink signal or channel is no longer received on the first time domain resource indicated as uplink by the information.

[0369] In some embodiments, in a first time domain resource, or in a first time domain resource indicated as downlink or uplink by information not used to indicate the link direction of the first time domain resource, if SSB is indicated, no uplink signal or channel is sent in the first time domain resource, or an uplink signal or channel is sent.

[0370] In some embodiments, the SSB is indicated by ssb-PositionsInBurst in SIB1 or ssb-PositionsInBurst in ServingCellConfigCommon or ssb-PositionsInBurst in SSB-MTCAdditionalPCI associated to physical cell ID with active TCI states for PDCCH or PDSCH, or configured for L1 beam measurement / reporting or NonCellDefiningSSB.

[0371] In some embodiments, an uplink signal or channel configured by a higher layer is not sent in the first time domain resource, and an uplink signal or channel scheduled by DCI is sent.

[0372] In some embodiments, information is received for instructing the terminal device to autonomously select the first time domain resource or the first time domain resource indicated as downlink or uplink in the link direction not used to indicate the first time domain resource not to send an uplink signal or channel (configured by a higher layer) or to send the uplink signal or channel (configured by a higher layer).

The method of the embodiment of the present application may also include other steps or processes. For the specific content of these steps or processes, reference may be made to the relevant art.

[0374] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0375] According to an embodiment of the present application, a terminal device obtains the resources of the network device operating in full-duplex mode based on information from the network device. As a result, the network device can operate in full-duplex mode (receiving and transmitting simultaneously), and the terminal device can also use the corresponding resources to send and receive signals when the network device operates in full-duplex mode. This can improve the capacity and coverage of uplink transmission, reduce the latency of uplink transmission, and improve resource allocation flexibility and resource utilization.
