[0013] The terminology used in the embodiments of this invention is merely for the purpose of describing specific embodiments and is not intended to limit the invention. The singular forms “one kind,” “the said,” and “the” used in this invention and the claims are also intended to include the plural form unless the context clearly indicates otherwise. Furthermore, it should be understood that the term “and / or” used in this invention includes any or all possible combinations of one or more related enumerated items.

[0014] The embodiments of the present invention may use terms such as first, second, third, etc., to describe various types of information, but it should be understood that this information is not limited to these terms. These terms are used solely to distinguish the same type of information. For example, without departing from the scope of the present invention, first information may be called second information, and similarly, second information may be called first information. Also, depending on the context, the word "…case" used may be interpreted as "…and," "…when," or "in response to a decision."

[0015] The TDD system can operate in HD mode, meaning that at the same time, the same frequency domain resources are available for either UL or DL ​​only. To use frequency domain resources more flexibly and improve resource utilization, the TDD system can also operate in FD (Full-Duplex) mode, meaning that at the same time, the same frequency domain resources are used simultaneously for UL and DL, and that is, uplink and downlink data are processed simultaneously on the same frequency domain resources.

[0016] In a TDD system, the frame structure is divided into DL slots, UL slots, and flexible slots. Once the frame structure is determined, the UE can transmit and receive data according to the frame structure. For UEs employing HD (Half Duplex) mode, the base station (e.g., gNB) schedules the UE to transmit or receive based on the frame structure. For UEs employing FD mode, the base station schedules the UE to transmit, receive, or transmit and receive simultaneously based on the frame structure. In summary, the base station can set the frame structure and notify the UE of the frame structure, allowing the UE to know the frame structure and perform data transmission and reception accurately. From another perspective, knowing the frame structure allows the UE to know about any potential interference between UEs, enabling them to employ interference rejection techniques to mitigate interference and improve communication reliability.

[0017] For example, in a TDD system, a frame structure primarily used for uplink transmission typically has many UL slots, resulting in fewer DL slots. This limits the downlink transmission speed and increases the transmission delay of downlink data, leading to greater delay in downlink transmission and disadvantages for downlink services.

[0018] In one example of the present invention, a subband resource determination method is provided for setting flexible downlink and uplink subband resources for a UE in a BWP. For example, uplink subband resources can be set using downlink slots or flexible slots, and uplink data can be transmitted using the uplink subband resources, thereby improving the uplink transmission rate and reducing the uplink data transmission delay by using downlink slots or flexible slots to transmit uplink data. Alternatively, downlink subband resources can be set using uplink slots or flexible slots, and downlink data can be transmitted using the downlink subband resources, thereby improving the downlink transmission rate and reducing the downlink data transmission delay by using uplink slots or flexible slots to transmit downlink data.

[0019] In one example of the present invention, a subband resource determination method applicable to UE is provided, Figure 1A being a schematic flowchart of the subband resource determination method, which may include the following steps.

[0020] Step 111, receive a subband resource instruction message transmitted from the base station, which may include frequency domain resource information for a first type subband, and the first type subband may be an uplink subband or a downlink subband.

[0021] Step 112, determine the start and / or end positions of the first type subband based on the frequency domain resources of the first type subband indicated by the frequency domain resource information of the first type subband, and determine the start or end position of the guard subband based on the start and / or end positions of the first type subband.

[0022] Step 113, receive a guard subband configuration message transmitted from the base station, which may include the length of the guard subband, such as how many PRBs the guard subband will occupy.

[0023] Step 114, determine the guard subband resource from the BWP using the start position and length of the guard subband, or determine the guard subband resource from the BWP based on the end position and length of the guard subband.

[0024] BWP is used to define SBFD frequency domain resources (i.e., SBFD subband resources), which may include uplink and downlink subband resources. Of course, BWP may also be used to define guard subband resources (guard subband resources do not belong to SBFD subband resources), and therefore guard subband resources may be determined from BWP.

[0025] In one example of the present invention, a subband resource determination method applicable to a base station is provided, and Figure 1B is a schematic flowchart of the subband resource determination method, which may include the following steps.

[0026] Step 121: Send a subband resource instruction message to the UE, which includes frequency domain resource information for a first type subband, and the subband resource instruction message is used to instruct the UE to determine the start and / or end positions of the first type subband based on the frequency domain resources of the first type subband indicated by the frequency domain resource information, and to determine the start or end position of the guard subband based on the start and / or end positions of the first type subband.

[0027] Step 122: Send a guard subband configuration message to the UE, which includes the length of the guard subband. The configuration message is used to instruct the UE to determine a guard subband resource from the BWP using the start position and length of the guard subband, or to determine a guard subband resource from the BWP based on the end position and length of the guard subband.

[0028] For example, the guard subband configuration message may be a semi-static configuration message, and the base station may send a semi-static configuration message to the UE, and the UE may receive a semi-static configuration message sent from the base station. The semi-static configuration message includes the length of the guard subband, that is, the UE can obtain the length of the guard subband from the semi-static configuration message.

[0029] In one example, the guard subband configuration messages may be semi-static and dynamic configuration messages. The base station may send a semi-static configuration message to the UE, and the UE may receive a semi-static configuration message sent from the base station. The semi-static configuration message may include a subband length list, which may include the lengths of multiple guard subbands. Next, the base station may send a dynamic configuration message to the UE, and the UE may receive a dynamic configuration message sent from the base station, which may include index information, which is used to instruct the UE to select the guard subband length corresponding to the index information from the subband length list. In this case, the UE can obtain the index information from the dynamic configuration message and obtain the guard subband length based on the index information.

[0030] In one example, the step by which the UE determines the start and / or end positions of a guard subband based on the start and / or end positions of the first type subband may include, if the first type subband is located on the upper edge of the BWP, the step of determining the end position of the guard subband based on the start position of the first type subband; or if the first type subband is located on the lower edge of the BWP, the step of determining the start position of the guard subband based on the end position of the first type subband; or if the first type subband is located in the middle of the BWP, the step of determining the start position of the guard subband located above the first type subband based on the end position of the first type subband, and determining the end position of the guard subband located below the first type subband based on the start position of the first type subband.

[0031] For example, the frequency domain resource information for a first type subband may include a Bitmap setting for the subband resource group occupied by the first type subband. If the Bitmap setting determines that the subband resource group corresponds to a first value, then the subband resource group is occupied by the first type subband. If the Bitmap setting determines that the subband resource group corresponds to a second value, then the subband resource group is not occupied by the first type subband. In this case, the UE can determine the frequency domain resources occupied by the first type subband based on the Bitmap setting of the subband resource group occupied by the first type subband. The first and second values ​​may be set empirically, for example, the first value is 1 and the second value is 0.

[0032] In one example, the frequency domain resource information for a first type subband may include a first subband resource indicator value corresponding to the first type subband, which is determined based on the location of the first type subband's starting physical resource block and the number of contiguous physical resource blocks occupied by the first type subband. In this case, the UE can derive the location of the first type subband's starting physical resource block and the number of contiguous physical resource blocks occupied by the first type subband based on the first subband resource indicator value, and determine the frequency domain resources occupied by the first type subband based on the location of the first type subband's starting physical resource block and the number of contiguous physical resource blocks occupied by the first type subband.

[0033] The process for obtaining the first subband resource instruction value is as follows:

number

[0034] In one example, the frequency domain resource information for a first type subband may include a second subband resource indicator corresponding to the first type subband, the second subband resource indicator being determined based on the location of the first type subband's starting subband resource group and the number of consecutive subband resource groups occupied by the first type subband. In this case, the UE can derive the location of the first type subband's starting subband resource group and the number of consecutive subband resource groups occupied by the first type subband based on the second subband resource indicator, and determine the frequency domain resources occupied by the first type subband based on the location of the first type subband's starting subband resource group and the number of consecutive subband resource groups occupied by the first type subband.

[0035] The process for obtaining the second subband resource instruction value is as follows:

number

number

number

[0036] For example, a base station may send a subband configuration type instruction message to the UE before sending a subband resource instruction message to the UE, and the UE may receive a subband configuration type instruction message sent from the base station. If the subband configuration type instruction message is used to indicate a Bitmap type, the subband resource instruction message indicates that it carries the Bitmap configuration of the subband resource group occupied by the first type subband, i.e., the UE determines the frequency domain resources occupied by the first type subband based on the Bitmap configuration of the subband resource group occupied by the first type subband.

[0037] Alternatively, if the subband setting type instruction message is used to indicate an SBRIV type, the subband resource instruction message indicates that it carries a first subband resource instruction value corresponding to the first type subband, i.e., the UE can analyze the first subband resource instruction value SBRIV and derive, based on the first subband resource instruction value SBRIV, the location of the starting physical resource block of the first type subband and the number of consecutive physical resource blocks occupied by the first type subband.

[0038] Alternatively, if the subband setting type instruction message is used to indicate the SBRIV and SBG types, the subband resource instruction message indicates that it carries a second subband resource instruction value corresponding to the first type subband, i.e., the UE can analyze the second subband resource instruction value SBRIV and derive, based on the second subband resource instruction value SBRIV, the location of the starting subband resource group of the first type subband and the number of consecutive subband resource groups occupied by the first type subband.

[0039] In one example, after the UE determines the guard subband resource from the BWP, if the frequency domain resource of the first type subband is an uplink subband resource, the downlink subband resource is determined from the BWP based on the uplink subband resource and the guard subband resource. If the frequency domain resource of the first type subband is a downlink subband resource, the uplink subband resource is determined from the BWP based on the downlink subband resource and the guard subband resource.

[0040] For example, a BWP may include multiple subband resource groups. After the UE determines a guard subband resource from the BWP, if the subband resource group is a frequency domain resource group that includes an uplink subband resource and a guard subband resource, the UE either transmits uplink data on the uplink subband resource of the subband resource group or prohibits the transmission of uplink data on the uplink subband resource of the subband resource group. If the subband resource group is a subband resource group that includes a downlink subband resource and a guard subband resource, the UE either receives downlink data on the downlink subband resource of the subband resource group or prohibits the reception of downlink data on the downlink subband resource of the subband resource group.

[0041] In one example, the first type subband may be a frequency domain resource configured in an SBFD symbol. The base station may send a frame configuration message to the UE, and the UE may receive a frame configuration message sent from the base station, which includes the start symbol and length of the SBFD symbol. The frame configuration message may be a semi-static frame configuration message. If the frame configuration message is a semi-static frame configuration message, it is either a TDD-UL-DL-ConfigCommon (common configuration) or a TDD-UL-DL-ConfigDedicated (dedicated configuration) in an RRC message.

[0042] The start symbol and length of an SBFD symbol are used to determine all SBFD symbols necessary to establish the first type subband. For example, the start symbol of an SBFD symbol represents the first symbol in the frame structure of the SBFD symbol, and the length of the SBFD symbol represents the number of symbols following the start symbol. Alternatively, the start symbol of an SBFD symbol represents the last symbol in the frame structure of the SBFD symbol, and the length of the SBFD symbol represents the number of symbols preceding the start symbol.

[0043] In one example, the first type subband may be a frequency domain resource configured for an SBFD symbol. The base station sends an RRC message to the UE, which receives the RRC message from the base station, which includes a number of slot format combinations, each slot format combination including a slot format type to indicate an SBFD symbol.

[0044] The base station may send a DCI message to the UE, and the UE may receive a DCI message sent from the base station, which includes an index of a target slot format combination. After receiving the DCI message, the UE selects a corresponding target slot format combination from a plurality of slot format combinations based on the index of the target slot format combination, and determines all SBFD symbols for setting up the first type subband based on the target slot format combination.

[0045] As can be seen from the above technical proposal, the UE determines the start or end position of the guard subband based on the subband resource instruction message. The UE determines the length of the guard subband based on the guard subband configuration message, determines the guard subband resource from the BWP, and distinguishes between the uplink subband resource, downlink subband resource, and guard subband resource in the BWP. The UE uses the SBFD subband resource (which includes both uplink and downlink subband resources) to transmit data, improving resource utilization, increasing network coverage and capacity, and reducing transmission delay.

[0046] The above technical proposal of the present invention will be explained below with reference to examples.

[0047] In a TDD system, the frame structure is divided into UL slots, DL slots, and flexible slots (F slots) according to the slots. The symbols in the flexible slots may be set to UL symbols, DL symbols, or F symbols, and the F symbols may be used for UL, DL, or GP. Uplink data may be transmitted in the UL slots, or in the UL symbols or F symbols in the flexible slots. Uplink data cannot be transmitted in the DL slots, nor in the DL symbols in the flexible slots. Downlink data may be transmitted in the DL slots, or in the DL symbols or F symbols in the flexible slots. Downlink data cannot be transmitted in the UL slots, nor in the UL symbols in the flexible slots.

[0048] Full-duplex communication may be implemented using the SBFD method, that is, an SBFD subband resource (subband, i.e., frequency domain resource) may be set in the BWP (Bandwidth Part), and the SBFD subband resource may include uplink and downlink subband resources. In this way, at the same time, data in different directions can be transmitted in the SBFD subband resource compared to other frequency domain resources. For example, by setting an SBFD subband resource in the BWP of a DL slot and transmitting uplink data using the SBFD subband resource, uplink data can be transmitted in the DL slot. By setting an SBFD subband resource in the BWP of a DL symbol in a flexible slot and transmitting uplink data using the SBFD subband resource, uplink data can be transmitted in the DL symbol of the flexible slot.

[0049] By setting an SBFD subband resource to the BWP in a UL slot and transmitting downlink data using the SBFD subband resource, downlink data will be transmitted in the UL slot. By setting an SBFD subband resource to the BWP of the UL symbol in a flexible slot and transmitting downlink data using the SBFD subband resource, downlink data will be transmitted in the UL symbol of the flexible slot.

[0050] For example, an SBFD subband resource may be a frequency domain resource in an SBFD slot or SBFD symbol, and an SBFD symbol may be defined as a symbol for an SBFD subband. In the SBFD subband of these SBFD symbols, base stations and UEs can perform full-duplex communication, that is, uplink transmission, downlink transmission, or simultaneous uplink and downlink transmission can be performed in the SBFD subband resource.

[0051] SBFD subband resources may be explicitly designated as uplink, downlink, or Flexible. When an SBFD subband resource is designated as Flexible, it can be flexibly scheduled for uplink or downlink. If an SBFD subband resource is not explicitly designated, it means Flexible and can be used to transmit uplink or downlink data. The SBFD symbol configuration may include which symbols in the DL, UL, and F slots are used for SBFD transmission, as well as the implementation period, start point, etc.

[0052] SBFD subband resources designated as uplink are called uplink subband resources and are abbreviated as UL SB; in other words, SBFD subband resources are used for uplink. SBFD subband resources designated as downlink are called downlink subband resources and are abbreviated as DL SB; in other words, SBFD subband resources are used for downlink. Frequency domain resources designated as guard subbands are called guard subband resources and are abbreviated as GB; in other words, they are used for guard subbands.

[0053] For half-duplex UEs that support SBFD functionality, the UE can know the settings for SBFD subband resources, but the UE can only receive downlink data or transmit uplink data at the same time (symbol).

[0054] The base station configures SBFD subband resources for half-duplex UEs that support SBFD functionality. In a DL slot or DL ​​symbol, an SBFD subband resource is configured for the UE, and the SBFD subband resource is used for uplink data transmission; that is, the SBFD subband resource may also be an uplink subband resource. A DL symbol on which an SBFD subband resource is configured is an SBFD symbol, and in an SBFD symbol, resources other than the uplink subband resource are downlink subband resources and guard subband resources, with the guard subband resource located between the uplink and downlink subband resources.

[0055] In a UL slot or UL symbol, an SBFD subband resource is set to the UE, and the SBFD subband resource is used for downlink data transmission; that is, the SBFD subband resource may also be a downlink subband resource. A UL symbol in which an SBFD subband resource is set is an SBFD symbol, and in an SBFD symbol, all resources except the downlink subband resource are uplink subband resources and guard subband resources, with the guard subband resource located between the uplink subband resource and the downlink subband resource.

[0056] In an F slot or F symbol, an SBFD subband resource is set to the UE, and the SBFD subband resource is used for transmitting downlink data (or uplink data). That is, the SBFD subband resource may be a downlink subband resource (or uplink subband resource). An F symbol in which an SBFD subband resource is set is an SBFD symbol, and in an SBFD symbol, everything except the downlink subband resource (or uplink subband resource) is an uplink subband resource (or downlink subband resource) and a guard subband resource, and the guard subband resource is located between the uplink subband resource and the downlink subband resource.

[0057] In one example, the base station in the subsequent embodiment is a full-duplex base station capable of processing downlink and uplink data simultaneously. The UE in the subsequent embodiment is a half-duplex UE that supports SBFD functionality and can process only downlink or uplink data at the same time, and can know all SBFD configuration parameters.

[0058] To support FD communication, SBFD subband resources may be configured semi-statically, for example by RRC (Radio Resource Control) signaling, or dynamically, for example by DCI (Downlink Control Information).

[0059] The time-domain resources of SBFD, i.e., the SBFD frame structure, may be configured by semi-static settings, or by a combination of semi-static settings and dynamic instructions, and SBFD symbols can also be modified by dynamic instructions.

[0060] First, configure the guard subband resources.

[0061] When configuring downlink and uplink subband resources in a BWP, it is necessary to configure a guard bandwidth (i.e., a guard subband resource) between the downlink and uplink subband resources. This guard subband resource can reduce interference between subbands, and therefore, it is necessary to configure a guard subband resource in a BWP.

[0062] For example, after setting up an uplink subband resource (UL SB) and a guard subband resource (GB) in a BWP, a downlink subband resource (DL SB) can be implicitly obtained. In other words, in a BWP, the remaining resources other than the uplink subband resource and guard subband resource are downlink subband resources.

[0063] Furthermore, for example, by setting downlink subband resources and guard subband resources in a BWP, uplink subband resources can be implicitly obtained based on the downlink subband resources and guard subband resources. In other words, in a BWP, the remaining resources other than downlink subband resources and guard subband resources are uplink subband resources.

[0064] Furthermore, for example, by setting up upstream and downstream subband resources in a BWP, a guard subband resource can be implicitly obtained based on the upstream and downstream subband resources. In other words, the remaining resources in a BWP, other than the upstream and downstream subband resources, are guard subband resources.

[0065] In one example, frequency domain resources and guard subband resources for the first type subband may be set, and frequency domain resources for the second type subband may be implicitly obtained, i.e., frequency domain resources and guard subband resources for the first type subband may be explicitly set. The frequency domain resources for the first type subband may be uplink subband resources, and the frequency domain resources for the second type subband may be downlink subband resources, i.e., uplink subband resources and guard subband resources may be explicitly set. Alternatively, the frequency domain resources for the first type subband may be downlink subband resources, and the frequency domain resources for the second type subband may be uplink subband resources, i.e., downlink subband resources and guard subband resources may be explicitly set.

[0066] For example, the following method may be used to explicitly configure guard subband resources.

[0067] The base station indicates the uplink sub-band resources, deletes the total number of PRBs occupied by the uplink sub-band resources from the BWP, the specific frequency domain position, the total number of PRBs occupied by the guard sub-band resources, and the specific frequency domain position, and the rest is the total number of PRBs occupied by the downlink sub-band resources and the specific frequency domain position. At this time, the guard sub-band resources may be clearly indicated or may be 0. There are two indication methods for the frequency domain resources of the guard sub-band resources. Table 1 is the first indication method for the frequency domain resources of the guard sub-band resources that indicates the starting PRB and the total number of frequency domain resources occupied (M*N), or Table 2 is the second indication method for the frequency domain resources of the guard sub-band resources that calculates the total number of guard sub-band resources occupied based on the starting and ending positions of the frequency domain resources.

Table 1

Table 2

[0068] Regarding the first indication method for the frequency domain resources of the guard sub-band resources, the guard sub-band resources are indicated by the starting position, the frequency domain resource allocation indication, and the frequency domain resource unit indication. The number of PRBs in the BWP is N PRB Yes, log2(N PRB ) bits of data are required for the starting position. If the number of selectable frequency domain resource units (P) for the frequency domain resource unit indication is N, then log2(N) bits are required. The frequency domain resource allocation indication is the ceiling of the value obtained by dividing the number of PRBs in the frequency domain resources by the frequency domain resource unit indication, that is, ceil(N PRB / P) bits. Taking a 100 MHz bandwidth, that is, 273 PRBs, 5 selectable frequency domain resource units in Table 1, and P = 16 PRBs as an example, log2(N PRB ) + log2(N) + ceil(N PRB / P) = 9 + 18 + 3 = 30 bits are required. If the uplink subband resource is located in the middle of the BWP, two guard bandwidths are required between the uplink and downlink subband resources, i.e., 60 bits are required.

[0069] Regarding the second indication method for frequency domain resources of guard subband resources, a method for displaying the start and end positions is adopted, and the number of PRBs in BWP is N PRB If that is the case, then both the start and end positions must clearly specify concrete locations, and one guard bandwidth must be 2*log2(N PRB ) bits are required. For example, with a 100MHz bandwidth, 18 bits are required for a single guard bandwidth. If the uplink subband resource is located midway along the BWP, two guard bandwidths are required between the uplink and downlink subband resources, i.e., 36 bits are needed.

[0070] Whether using the first or second instruction method, instructing guard subband resources requires many bits, which significantly increases signaling overhead and reduces the data transmission rate.

[0071] In response to the above discovery, a method may be adopted in which the base station sends a guard subband configuration message to the UE and the UE receives the guard subband configuration message, the guard subband configuration message including the length of the guard subband. The UE can determine the start or end position of the guard subband using the start and / or end positions of the first type subband, and can determine the guard subband resource from the BWP using the start position and length of the guard subband, or can determine the guard subband resource from the BWP based on the end position and length of the guard subband.

[0072] For example, when it is necessary to explicitly configure guard subband resources, this may be done using a semi-static or dynamic configuration method, and the guard subband resources may be configured together with the frequency domain resources of the first type subband (e.g., uplink subband resources). The length of the guard subband can be flexibly configured according to the actual scenario; for example, in scenarios with highly fading frequency selectivity, interference between subbands can be reduced by setting the longest possible guard bandwidth. By explicitly configuring guard subband resources, it is possible to adapt to the needs of different scenarios.

[0073] When semi-static configuration is adopted, the guard subband configuration message may also be a semi-static configuration message; that is, the guard subband resource is configured in the UE by a semi-static configuration message (e.g., an RRC message). The base station selects the length of the guard subband from a set of selectable lengths and sends the guard subband length to the UE via an RRC message, and the UE obtains the guard subband length from the RRC message based on the agreement between the base station and the UE.

[0074] For example, the length of the guard subband may be a value such as {1, 2, 3, 4, 5, 6, 7, 8, 16}, or of course, only a few typical values ​​such as {1, 2, 4, 6, 8} may be set. Of course, the above are just some examples of selectable lengths, and the selectable values ​​for the guard subband length can be set arbitrarily without limitation. The length of the guard subband is an optional parameter, and if not set, the base station will guarantee the guard bandwidth between UL and DL through dynamic scheduling.

[0075] An example of setting parameters for an RRC message is as follows: guardBandSizeInSbfd enumerate{1,2,3,4,5,6,7,8}, optional

[0076] For example, a base station can select one value from {1, 2, 3, 4, 5, 6, 7, 8} as the length of the guard subband, and the base station can transmit the length of the guard subband to the UE via the RRC message.

[0077] When dynamic configuration is adopted, the guard subband configuration messages may be semi-static configuration messages and dynamic configuration messages, the semi-static configuration messages may be RRC messages, and the dynamic configuration messages may be DCI messages.

[0078] A base station can send an RRC message to the UE, via the RRC message, a selectable guard bandwidth list (also called a subband length list) can be sent to the UE, which may contain multiple guard subband lengths, an example of which is sbfdGuardBandList sequence{1,2,3,4,5,6,7,8}, where the lengths of the multiple guard subbands may be {1,2,3,4,5,6,7,8}, but are not limited to this.

[0079] Next, the base station can send a DCI message to the UE, via which the base station sends a guard bandwidth instruction to the UE, which is index information, and this index information is used to indicate the index value of the guard bandwidth list, i.e., the length of which guard subband in the guard bandwidth list.

[0080] The size of the guard bandwidth instruction is log2(sizeof(sbfdGuardBandList)), and referring to the aforementioned guard bandwidth list, the bit size occupied by the guard bandwidth instruction is log2(8) = 3 bits, where 0 corresponds to the first value in the guard bandwidth list, 1 corresponds to the second value in the guard bandwidth list, and so on.

[0081] A new parameter may be introduced to the DCI message, which represents a guard bandwidth indicator, for example, sbfdGuardBandIndicator.

[0082] Based on the guard bandwidth indication in the DCI message, the UE can select the length of the guard subband corresponding to the guard bandwidth indication from the subband length list, i.e., obtain the length of the guard subband.

[0083] In one example, the guard subband resources are set to a fixed size and are adjacent to the frequency domain resources of the first type subband (e.g., uplink or downlink subband resources), and the portion of the first type subband other than the guard subband resources is the frequency domain resources of the second type subband (e.g., downlink or uplink subband resources), and the number of guard subband resources is determined based on the position of the frequency domain resources of the first type subband.

[0084] For example, if the frequency domain resource of the first type subband is located in the middle of the BWP, there are two guard subband resources, each located between the frequency domain resource of the first type subband and the frequency domain resources of the second type subbands on either side. If the frequency domain resource of the first type subband is located at one end of the BWP, there is only one guard subband resource, which is located between the frequency domain resource of the first type subband and the frequency domain resource of the second type subband.

[0085] If the frequency domain resources of the first type subband are not set from the edge of the BWP, and the number of PRBs from the edge of the BWP to the nearest PRB within the frequency domain resources of the first type subband is less than the number of resources in the guard subband resources, then there are no frequency domain resources of the second type subband between the edge of the BWP and the frequency domain resources of the first type subband.

[0086] In one example, the UE can determine the start or end position of a guard subband based on the start and / or end positions of a first type subband, and can determine a guard subband resource from the BWP using the start position and length of the guard subband, or can determine a guard subband resource from the BWP based on the end position and length of the guard subband.

[0087] If the first type subband is located on the upper edge of the BWP, the UE can determine the end position of the guard subband based on the start position of the first type subband. Alternatively, if the first type subband is located on the lower edge of the BWP, the UE can determine the start position of the guard subband based on the end position of the first type subband. Alternatively, if the first type subband is located in the middle of the BWP, the UE can determine the start position of the guard subband located above the first type subband based on the end position of the first type subband, and the end position of the guard subband located below the first type subband based on the start position of the first type subband.

[0088] After determining the guard subband resources, the UE can determine the frequency domain resources of the second type subband from the BWP based on the frequency domain resources of the first type subband and the guard subband resources. For example, if the frequency domain resources of the first type subband are uplink subband resources, the downlink subband resources are determined from the BWP based on the uplink subband resources and the guard subband resources. If the frequency domain resources of the first type subband are downlink subband resources, the uplink subband resources are determined from the BWP based on the downlink subband resources and the guard subband resources.

[0089] The granularity of a subband frequency domain resource group may be determined using a frequency domain resource unit designation, and a subband frequency domain resource group is also called an SBG, and the granularity of an SBG may be equal to that of an RBG.

[0090] Taking the example that the frequency domain resource of the first type subband is an uplink subband resource, Figure 2 is a schematic diagram of the setting of the uplink subband resource and guard subband resource. The uplink subband resource is located in the middle of the BWP, and the BWP may contain 17 SBGs (Subband Groups, also called subband resource groups or subband resource granularity), where SBGs are equal to RBGs, that is, the BWP contains 17 RBGs such as RBG0 to RBG16 in Figure 2.

[0091] As shown in Figure 2, the size of an RB is 8 PRBs, and due to the limit on the total number of PRBs, the number of PRBs corresponding to the last RB may be 8 or less. For example, RBG0 corresponds to PRBs 0-7, RBG1 corresponds to PRBs 8-15, ..., RBG16 corresponds to PRBs 128-132.

[0092] Referring to Figure 2, if the uplink subband resource is located in the middle of the BWP, there are two guard subband resources, one of which corresponds to RBG4, and the size of this guard subband resource is four PRBs, for example, this guard subband resource corresponds to PRBs 36-39, and this guard subband resource is located between the uplink and downlink subband resources. Clearly, for this guard subband resource, the UE can determine the end position of the guard subband located below the uplink subband resource (i.e., the 39th PRB) by the start position of the uplink subband resource (i.e., the 40th PRB).

[0093] Another guard subband resource corresponds to RBG13, and the size of this guard subband resource is four PRBs, for example, corresponding to PRBs 104-107, and this guard subband resource is located between the upstream subband resource and the downstream subband resource. Clearly, with respect to this guard subband resource, the UE can determine the start position of the guard subband located above the upstream subband resource (i.e., the 104th PRB) by the end position of the upstream subband resource (i.e., the 103rd PRB).

[0094] For example, unlike the size of the guard subband resources and the RB, the two may not be aligned; that is, an RB may contain both guard subband resources and uplink subband resources simultaneously, meaning some PRBs are set as guard subbands and the remaining PRBs are set as uplink subbands. Alternatively, an RB may contain both guard subband resources and downlink subband resources simultaneously, meaning some PRBs are set as guard subbands and the remaining PRBs are set as downlink subbands. If this RB is not used when performing PDSCH scheduling, resource waste will occur, resulting in the waste of some resources as shown in PRB36-39 and PRB104-107 in Figure 2.

[0095] To avoid wasting resources, after the UE determines a guard subband resource from the BWP, if the subband resource group is a frequency domain resource group that includes an uplink subband resource and a guard subband resource, the UE may transmit uplink data on the uplink subband resource of the subband resource group, or the UE may prohibit the transmission of uplink data on the uplink subband resource of the subband resource group. If the subband resource group is a subband resource group that includes a downlink subband resource and a guard subband resource, the UE may receive downlink data on the downlink subband resource of the subband resource group, or the UE may prohibit the reception of downlink data on the downlink subband resource of the subband resource group.

[0096] For example, when a base station uses Frequency Domain Resource Allocation (FDRA0) when scheduling a UE, the RBG occupied by the guard subband resource may still be instructed to be used, but the size of the RBG is promised to be the RBG size minus the size of the guard subband resource. That is, when making a PDSCH call to the UE, the RBG occupied by the guard subband resource is instructed to be 1, but both the base station and the UE assume that only the PRB of the RBG not occupied by the guard subband resource will be used. Accordingly, when calculating the PDSCH Transport Block Size (TBS), the PRB occupied by the guard subband resource in the RBG is removed.

[0097] When a base station employs frequency domain resource allocation type 1 (FDRA1) when scheduling a UE, the RBG occupied by the guard subband resource is not used, and the base station does not use the PRB occupied by the guard subband resource when scheduling a PDSCH.

[0098] Setting up frequency domain resources for the second and first type subbands.

[0099] The base station may send a subband resource instruction message to the UE, which includes frequency domain resource information for a first type subband, and the UE can determine the frequency domain resource for the first type subband from the BWP based on the frequency domain resource information for the first type subband. The first type subband may be an uplink subband or a downlink subband, and the frequency domain resource for the first type subband may be an uplink subband resource or a downlink subband resource.

[0100] For example, the frequency domain resources for the first type subband may be set as follows:

[0101] Method 1: Subband configuration based on bitmap.

[0102] When a first-type subband and a guard subband are explicitly set, the first-type subband is set using a bitmap method, which is called the bitmap method. To conserve bits, the frequency domain resource granularity of the subband may be determined using a frequency domain resource unit instruction, which is also called a subband resource group (SBG), and the granularity of the SBG may be equal to that of the RBG. After the SBG is determined, the number of bits occupied by the subband resource allocation instruction (Bitmap) is determined based on the size of the BWP, i.e.,

number

number

number

number

[0103] Next, a Bitmap is used to determine the resources occupied by the first type subband. A "1" in the Bitmap indicates that the corresponding frequency domain resource within the SBG is allocated to the frequency domain resource of the first type subband, while a "0" in the Bitmap indicates that the corresponding frequency domain resource within the SBG is not allocated to the frequency domain resource of the first type subband.

[0104] As shown in Figure 2, taking the first type subband as an example, the uplink subband is located in the middle of the BWP, the SBG is 8, the size of the guard subband is 4 PRBs, the two guard subbands are located between the uplink subband and the downlink subbands on either side, and the subband resource allocation instruction Bitmap is set to 00000111111110000.

[0105] In summary, the frequency domain resource information for the first type subband may include a Bitmap setting for the subband resource group occupied by the first type subband. If the Bitmap setting determines that the subband resource group corresponds to a first value (e.g., 1), then the subband resource group is occupied by the first type subband. If the Bitmap setting determines that the subband resource group corresponds to a second value (e.g., 0), then the subband resource group is not occupied by the first type subband. In this case, the UE determines the frequency domain resources occupied by the first type subband based on the Bitmap setting of the subband resource group occupied by the first type subband.

[0106] In one example, when implicitly setting a guard subband resource, that is, explicitly setting an uplink and downlink subband resource, and deriving the guard subband resource based on the uplink and downlink subband resources, it is necessary to set a Bitmap for the uplink and downlink subband resources, respectively. When specifying the uplink and downlink subband resources using the bitmap method, the size of the guard subband resource is an integer multiple of the RGB.

[0107] Method 2: Subband configuration based on subband resource instruction values.

[0108] When a first-type subband is explicitly defined, the first-type subband is determined by a Subband Resource Indication Value (SBRIV), which consists of its starting position and length. This method is called the SBRIV method. The SBRIV is determined by the starting PRB position RB of the first-type subband. Start And the number of consecutive PRBs L occupied by the first type subband RB It may be determined based on the following, and the starting PRB position RB of the first type subband Start PRB StartAlso written as such, it refers to the number of consecutive PRBs L occupied by the first type subband. RB is L PRB It is also written as follows:

[0109] In summary, the frequency domain resource information for the first type subband may include the subband resource indicator SBRIV (referred to as the first subband resource indicator for ease of distinction) corresponding to the first type subband, and the first subband resource indicator is the position PRB of the starting physical resource block of the first type subband. Start and the number of continuous physical resource blocks L occupied by the first type subband PRB This is determined by the following: In this case, the UE determines the starting physical resource block location PRB of the first type subband based on the first subband resource instruction value SBRIV. Start and the number of continuous physical resource blocks L occupied by the first type subband PRB By deriving this, the frequency domain resources occupied by the first type subband can be determined based on the location of the starting physical resource block of the first type subband and the number of continuous physical resource blocks occupied by the first type subband.

[0110] The process for obtaining the first subband resource instruction value is as follows:

number

number

number

[0111] Here,

number

[0112] For example, if the first type subband is an uplink subband, and a guard subband resource is explicitly configured, the guard subband resource is adjacent to the uplink subband resource (known as SBRIV). In the entire BWP, excluding the uplink and guard subband resources, the remaining resources are downlink subband resources.

[0113] For example, when a subband resource instruction message is set semi-statically, the subband resource instruction message may be an RRC message, and an uplink subband resource is indicated by introducing a new parameter to the RRC message, for example, the new parameter may be ulSubband, and the size of the bits it occupies is

number

[0114] Referring to Figure 2, the size of the guard subband resource is 4, there is only one uplink subband resource, the length of the uplink subband resource is 64PRB, the starting position is 40, and the RRC message can be found in Table 3. [Table 3]

[0115] For example, if a subband resource instruction message is set dynamically, the subband resource instruction message may be a DCI message, and an example of a DCI message can be found in Table 4. [Table 4]

[0116] For example, when implicitly configuring guard subband resources, that is, when explicitly configuring uplink and downlink subband resources, it is necessary to introduce a configuration parameter for the downlink subband resource, such as dlSubband, in addition to ulSubband, and the number of parameters required will depend on the number of downlink subband resources.

[0117] Method 3: Subband configuration based on subband resource indication values ​​and subband resource groups.

[0118] When explicitly setting the first type subband, it can be set in units of SBG, and SBRIV is the starting SBG position of the first type subband. Start and the number of consecutive SBGs L occupied by the first type subband SBG This method is determined by a system called the SBRIV+SBG method, in which the first type subband is determined by a Subband Resource Indication Value (SBRIV) consisting of the starting SBG position and the number of SBGs.

[0119] In summary, the frequency domain resource information for the first type subband may include the subband resource indicator SBRIV (referred to as the second subband resource indicator for ease of distinction) corresponding to the first type subband, and the second subband resource indicator is the position SBG of the starting subband resource group of the first type subband. Start and the number of continuous subband resource groups L occupied by the first type subband. SBGThis is determined by the following: In this case, the UE determines the position of the starting subband resource group of the first type subband based on the second subband resource indicator value SBRIV. Start and the number of continuous subband resource groups L occupied by the first type subband. SBG By deriving this, the frequency domain resources occupied by the first type subband can be determined based on the position of the starting subband resource group of the first type subband and the number of consecutive subband resource groups occupied by the first type subband.

[0120] The process for obtaining the second subband resource instruction value is as follows:

number

number

number

number

number

[0121] For example, if the first type subband is an uplink subband, and a guard subband resource is explicitly configured, the guard subband resource is adjacent to the uplink subband resource (known as SBRIV). In the entire BWP, excluding the uplink and guard subband resources, the remaining resources are downlink subband resources.

[0122] For example, when a subband resource instruction message is set semi-statically, the subband resource instruction message may be an RRC message, and an uplink subband resource is indicated by introducing a new parameter to the RRC message, for example, the new parameter may be ulSubband, and the size of the bits occupied by the ulSubband parameter is

number

[0123] As shown in Figure 2,

number

number

number

[0124] For example, if a subband resource instruction message is set dynamically, the subband resource instruction message may be a DCI message, and an example of a DCI message can be found in Table 6. [Table 6]

[0125] As can be seen from the parameter sizes of Methods 2 and 3, when using the SBRIV+SBG method, the required signaling overhead is far smaller than when using the SBRIV method, thus saving signaling overhead.

[0126] For example, when implicitly configuring guard subband resources, that is, when explicitly configuring uplink and downlink subband resources, it is necessary to introduce a configuration parameter for the downlink subband resource, such as dlSubband, in addition to ulSubband, and the number of parameters required will depend on the number of downlink subband resources.

[0127] For example, the base station may notify the UE in advance of the method used to set up the frequency domain resources of the first type subband, so that the UE can determine the frequency domain resources of the first type subband according to the correct resource allocation method, and thus determine the guard subband resources and the frequency domain resources of the second type subband. For example, the base station may send a subband setting type instruction message to the UE before sending a subband resource instruction message to the UE, and this subband setting type instruction message may be an RRC message or another type of message.

[0128] When a subband configuration type instruction message is used to indicate a Bitmap type, the subband resource instruction message indicates that it carries the Bitmap configuration of the subband resource group occupied by the first type subband, and the UE determines the frequency domain resources occupied by the first type subband based on the Bitmap configuration, i.e., determines the frequency domain resources occupied by the first type subband using method 1.

[0129] Alternatively, if the subband setting type instruction message is used to indicate the SBRIV type, the subband resource instruction message indicates that it carries a first subband resource instruction value corresponding to the first type subband, and the UE can analyze the first subband resource instruction value SBRIV and determine the frequency domain resources occupied by the first type subband based on the first subband resource instruction value SBRIV, that is, it can determine the frequency domain resources occupied by the first type subband using method 2.

[0130] Alternatively, if the subband setting type instruction message is used to indicate the SBRIV and SBG types, the subband resource instruction message indicates that it carries a second subband resource instruction value corresponding to the first type subband, and the UE can analyze the second subband resource instruction value SBRIV and determine the frequency domain resources occupied by the first type subband based on the second subband resource instruction value SBRIV, that is, it can determine the frequency domain resources occupied by the first type subband using method 3.

[0131] An example of a subband configuration type instruction message (RRC message) is sbfdFdraType Enumerate{Type0,Type1,Type2} OPTIONAL. Type0 represents the Bitmap type, Type1 represents the SBRIV type, and Type2 represents the SBRIV and SBG types. For example, the parameter sbfdFdraType Enumerate is set when SBFD is enabled and not set when SBFD is disabled.

[0132] Third, setting SBFD symbols. SBFD subband resources may be frequency domain resources set in SBFD symbols, and in order to set SBFD subband resources, SBFD symbols must be set. For example, the first type subband is a frequency domain resource set in an SBFD symbol, and the second type subband is a frequency domain resource set in an SBFD symbol.

[0133] The TDD frame structure is divided into UL slots, DL slots, and S slots on a slot-by-slot basis. The symbols in the S slots may be set to UL symbols, DL symbols, and Flexible (F) symbols, and the F symbols may be used for UL, DL, or GP. Regarding the TDD frame structure, the base station can notify the UE using the semi-static configuration modes TDD-UL-DL-ConfigCommon / TDD-UL-DL-ConfigDedicated.

[0134] In TDD-UL-DL-ConfigCommon, up to two frame structure patterns can be configured. Each pattern can define the period of the frame structure and the specific settings for each slot and symbol within that period (e.g., DL, UL, or F). These two patterns work together to determine the current overall frame structure.

[0135] A semi-statically configured frame structure in TDD is shown in Figure 3. The up / down setting is 1:4, the S slot is slot 3, symbols #10 and #11 are set to F symbols and used for the GP for switching between up and down.

[0136] In TDD-UL-DL-ConfigDedicated, you may change the symbol set for F in TDD-UL-DL-ConfigCommon and further set the F symbol to DL or UL.

[0137] Furthermore, the TDD frame structure may be dynamically instructed by DCI, and it is permitted to send a Slot Format Indicator (SFI) by DCI format 2_0 to change the F symbol and then set it to a DL or UL symbol, but it is not permitted to change semi-statically set DL and UL symbols.

[0138] In the above method, the semi-static setting method for the frame structure does not allow for setting SBFD symbols because their positions are not clearly indicated. On the other hand, since DL and UL symbols cannot be changed by DCI dynamic instructions, it is disadvantageous for flexibly adjusting the position of SBFD symbols.

[0139] In response to the above findings, this embodiment proposes a method for setting SBFD symbols that includes both a semi-static setting method and a dynamic setting method for SBFD symbols, which will be described below.

[0140] Case 1: Semi-static configuration method for SBFD symbols.

[0141] The base station may send a frame structure configuration message to the UE, which receives the frame structure configuration message, which may be a semi-static frame structure configuration message, which includes the start symbol and length of the SBFD symbols. Based on the start symbol and length of the SBFD symbols, the UE can determine all the SBFD symbols for configuring SBFD subband resources (e.g., uplink subband resources and downlink subband resources).

[0142] For example, an SBFD symbol (time-domain resource) may be indicated by a semi-static frame structure configuration message, which may be an RRC message, such as TDD-UL-DL-ConfigCommon (common configuration) or TDD-UL-DL-ConfigDedicated (dedicated configuration). For example, an SBFD frame structure is DXXXU, where X represents a slot containing an SBFD symbol, which contains one or more SBFD symbols.

[0143] For example, an SBFD symbol may be set semi-statically, defined by its starting symbol and its length. Here, the starting symbol represents the first symbol in the SBFD symbol's frame structure pattern (e.g., a symbol index value counted from the first symbol), and the length of the SBFD symbol represents the number of symbols following the starting symbol. Alternatively, the starting symbol represents the last symbol in the SBFD symbol's frame structure pattern (e.g., a symbol index value counted from the last symbol), and the length of the SBFD symbol represents the number of symbols preceding the starting symbol.

[0144] For flexibility, two SBFD-related patterns can be set within a single frame structure cycle. The two SBFD patterns are selectable, are only enabled in SBFD mode, and correspond one-to-one with the current frame structure pattern. Each pattern contains two sets of SBFD symbol configuration information, each set including a start symbol and length. Both sets of SBFD configuration information are selectable.

[0145] The value of the starting symbol in the first set of configuration information represents the first symbol of the SBFD, counted from the first symbol in the current frame structure pattern, and the length represents the length of the symbols that follow the SBFD.

[0146] The value of the starting symbol in the second set of configuration information represents the first symbol of the SBFD, counted from the last symbol in the current frame structure pattern, and the length represents the length of the symbols that follow the SBFD.

[0147] Each pair of SBFD symbols is counted from its starting symbol, and if the length exceeds the range of the frame structure pattern period, the excess portion is invalid. Whether or not the two pairs of SBFD symbols overlap is not limited and is actually determined by the base station.

[0148] For example, the RRC message for setting the SBFD symbol is shown below. TDD-UL-DL-ConfigCommon ::= SEQUENCE { referenceSubcarrierSpacing SubcarrierSpacing, pattern1 TDD-UL-DL-Pattern, SBFDPattern1 TDD-UL-DL-Pattern-SBFD optional, pattern2 TDD-UL-DL-Pattern, SBFDPattern2 TDD-UL-DL-Pattern-SBFD optional, } TDD-UL-DL-Pattern-SBFD::= SEQUENCE { startSymbolOfSbfd1 INTEGER (0..maxNrofSlots* maxNrofSymbols), optional nrofSbfdSymbols1 INTEGER (0..maxNrofSlots* maxNrofSymbols), optional startSymbolOfSbfd2 INTEGER (0..maxNrofSlots* maxNrofSymbols), optional nrofSbfdSymbols2 INTEGER (0..maxNrofSlots* maxNrofSymbols), optional }

[0149] Case 2: Dynamic setting method for SBFD symbols.

[0150] The base station may send an RRC message to the UE, which receives the RRC message, which may contain multiple slot format combinations, each slot format combination containing a slot format type for indicating an SBFD symbol. The base station may send a DCI message to the UE, which receives the DCI message, which may contain an index of a target slot format combination. After receiving the DCI message, the UE can select a corresponding target slot format combination from multiple slot format combinations based on the index of the target slot format combination, and based on the target slot format combination, determine all the SBFD symbols for configuring SBFD subband resources (e.g., uplink subband resources and downlink subband resources).

[0151] For example, SBFD symbols may be set dynamically, and this dynamic setting is achieved through a slot format instruction scheme. Given that the slot structure only contains D, U, and F symbols, to better support SBFD, a new slot format type is introduced when SBFD is enabled, and this new slot format type is denoted as the X symbol. The X symbol represents an SBFD symbol; that is, in SBFD mode, there are four symbol types: D, U, F, and X. Thus, the slot format type of an SBFD symbol can be specified using the slot format instruction scheme.

[0152] For example, the TDD frame structure is completed by a combination of semi-static configuration and dynamic instruction, and in upper-layer signaling, the SFI defines multiple slot format combinations (SFCs). For example, a base station selects slot formats that meet its service needs and adds these slot formats to the SFC, some of which are shown in Table 7. D represents DL symbols, U represents UL symbols, and F represents Flexible symbols. Each SFC is identified by a fixed ID and contains one or more slot format types. After the SFI configuration is complete, the base station sends the multiple slot format combinations to the UE in an RRC message. [Table 7]

[0153] After configuring multiple slot format combinations via RRC messages, the base station notifies the UE of the SFC index to be used in DCI format 2_0 via periodic PDCCH (Physical Downlink Control Channel). Part of the information structure of DCI format 2_0 is shown below. - If the higher layer parameter slotFormatCombToAddModList is configured, -Slot format indicator 1, Slot format indicator 2, …, Slot format indicator N

[0154] When configuring the slot structure using the SFI method, only the F symbol in the slot structure can be changed.

[0155] In the SBFD system, multiple SBFD SFCs are configured in a similar semi-static manner, and the SFI in DCI indicates which specific SBFD SFC to use. However, in the dynamic configuration of SBFD symbols, any symbol can be changed using the SFI method, changing D / U / F to X, or F / X to D or U. To facilitate distinction from the slot formats in Table 7, a new slot format is introduced for SBFD as shown in Table 8, changing F to X in all slot formats (#2 to #55) where the F symbol exists in slot format indices #0 to #55, and defining a new slot format type from #56. [Table 8]

[0156] Once the position of the SBFD symbol in the slot is clarified, one can select the appropriate slot format index in Table 8. When this slot format index is added to the SFC of the SBFD, the X symbol represents the SBFD symbol. For example, an example of an RRC message in the SFC is shown below. SlotFormatCombinationsPerCell ::= SEQUENCE { ... slotFormatCombinations SEQUENCE (SIZE (1..maxNrofSlotFormatCombinationsPerSet)) OF SlotFormatCombination OPTIONAL, slotFormatCombinations-SBFD SEQUENCE (SIZE (1..maxNrofSlotFormatCombinationsPerSet)) OF SlotFormatCombination-SBFD OPTIONAL, ..., }

[0157] Here, SlotFormatCombination-SBFD represents an SBFD slot format combination field, which may include a combination identifier and a slot format index corresponding to the SBFD slot format combination. The SlotFormatCombination-SBFD field can contain up to maxNrofSlotFormatCombinationsPerSet elements, and the definition of each element is as follows. SlotFormatCombination-SBFD ::= SEQUENCE { slotFormatCombinationId - SBFD SlotFormatCombinationId, slotFormats-SBFD SEQUENCE (SIZE (1..maxNrofSlotFormatsPerCombination)) OF INTEGER (0..255) }

[0158] Here, slotFormatCombinationId-SBFD represents an identifier, whose value ranges from 0 to maxNrofSlotFormatCombinationsPerSet-1, i.e., the value can be 0, 1, 2, ..., maxNrofSlotFormatCombinationsPerSet-1, etc. slotFormats-SBFDx represents the unique slot format index of the slot format, and a maximum of maxNrofSlotFormatsPerCombination can be set. The slot format index value is selected from Table 8, and the range of each index value may be 0 to 255. After slotFormatCombinationId-SBFD is set, slotFormatCombinations is ignored, i.e., the slot structure setting in SBFD mode overrides the slot structure setting in non-SBFD mode. Conversely, if slotFormatCombinations-SBFD is not set, the frame structure depends on the setting of slotFormatCombinations, i.e., it operates in the mode of conventional TDD.

[0159] When using DCI to specify the SFI for SBFD, continue using DCI format 2_0 but introduce a new SFI for SBFD. The settings in DCI format 2_0 are shown below, where SBFD Slot format indicator 1, SBFD Slot format indicator 2, ..., SBFD Slot format indicator N each correspond to slotFormatCombinationId-SBFD within SlotFormatCombination-SBFD. - If the higher layer parameter slotFormatCombToAddModList is configured, - if the higher layer parameter slotFormatCombinations-SBFD is configured -SBFD Slot format indicator 1, SBFD Slot format indicator 2, …, SBFD Slot format indicator N, - else -Slot format indicator 1, Slot format indicator 2, …, Slot format indicator N

[0160] When D / U / F is set to X, the activated and enabled subband resource settings are used; that is, the settings for the uplink subband resource, downlink subband resource, and guard subband resource in the newly set X symbol are the same as the subband resource settings in other X symbols. When changing from X to D or U, the X symbol is changed to a full D or full U symbol.

[0161] As can be seen from the above technical proposal, the UE determines the start or end position of the guard subband based on the subband resource instruction message. Based on the guard subband setting message, the UE determines the length of the guard subband and can determine the guard subband resource from the BWP, and distinguish between uplink subband resources, downlink subband resources, and guard subband resources in the BWP. The UE uses the SBFD subband resources to transmit data, improve resource utilization, improve network coverage and network capacity, and reduce downlink transmission delay.

[0162] By setting a fixed guard bandwidth, SBFD frequency domain resource configuration can be completed simply by configuring uplink or downlink subband resources, reducing air interface signaling overhead. By proposing different subband frequency domain resource configuration methods, flexible configuration of subband frequency domain resources is possible, and the air interface signaling overhead differs for each method, allowing for flexible selection. SBFD symbols can be flexibly configured; by changing D / U / F symbols to X symbols, or X / F symbols to D / U symbols, SBFD symbols can be flexibly changed according to the needs of the scenario.

[0163] To better support SBFD communication systems and ensure compatibility with TDD systems, subband frequency domain resources are configured for SBFD communication. By configuring SBFD subband frequency domain resources using a method that sets the size of the downlink or uplink subband and guard bandwidth, and by submitting different subband configuration policies, the SBFD subband frequency domain resource configuration is completed, reducing air interface signaling overhead and utilizing more air interface resources for data transmission. Once subband frequency domain resources are configured, the BWP can be dynamically set, allowing for flexible adjustment of the BWP to accommodate different scenarios.

[0164] Based on the same concept, we further provide a subband resource determination device, base station, and UE corresponding to the subband resource determination method. Since the principle by which the base station and UE solve the problem is similar to that of the subband resource determination method, the implementation of the base station and UE should refer to the subband resource determination method, and redundant explanations will be omitted.

[0165] Based on the same concept as described above, as shown in Figure 4A, an example of the present invention is a subband resource determination device applied to user equipment, A receiving module 41 for receiving a subband resource instruction message transmitted from a base station, wherein the subband resource instruction message includes frequency domain resource information for the first type subband, and the receiving module 41 The system includes a determination module 42 for determining the start and / or end positions of the first type subband based on the frequency domain resources of the first type subband indicated by the frequency domain resource information of the first type subband, and for determining the start or end position of the guard subband based on the start and / or end positions of the first type subband, The receiving module 41 is further used to receive a guard subband setting message transmitted from the base station, the guard subband setting message includes the length of the guard subband, The determination module 42 further provides a subband resource determination device used to determine a guard subband resource from a BWP using the start position and length of the guard subband, or to determine a guard subband resource from a BWP based on the end position and length of the guard subband.

[0166] In one example, when the receiving module 41 receives a guard subband setting message transmitted from the base station, specifically, Used to receive a semi-static configuration message transmitted from a base station, the semi-static configuration message includes the length of the guard subband, Or, It is used to receive semi-static configuration messages transmitted from a base station and to receive dynamic configuration messages transmitted from a base station, wherein the semi-static configuration message includes a subband length list, the subband length list includes the lengths of a plurality of guard subbands, and the dynamic configuration message includes index information, which is used to instruct the selection of the guard subband length corresponding to the index information from the subband length list.

[0167] In one example, when the determination module 42 determines the start or end position of the guard subband based on the start and / or end positions of the first type subband, specifically, If the first type subband is located on the upper edge of the BWP, the end position of the guard subband is determined by the start position of the first type subband, or If the first type subband is located on the lower edge of the BWP, the starting position of the guard subband is determined by the ending position of the first type subband, or When the first type subband is located in the middle of the BWP, the end position of the first type subband is used to determine the start position of the guard subband located above the first type subband, and the start position of the first type subband is used to determine the end position of the guard subband located below the first type subband.

[0168] In one example, the frequency domain resource information of the first type subband includes a Bitmap setting for the subband resource group occupied by the first type subband, and if it is determined based on the Bitmap setting that the subband resource group corresponds to a first value, then the subband resource group is occupied by the first type subband, and if it is determined based on the Bitmap setting that the subband resource group corresponds to a second value, then the subband resource group is not occupied by the first type subband, or The frequency domain resource information for the first type subband includes a first subband resource indicator value corresponding to the first type subband, the first subband resource indicator value is determined based on the location of the starting physical resource block of the first type subband and the number of continuous physical resource blocks occupied by the first type subband, or The frequency domain resource information for the first type subband includes a second subband resource indicator corresponding to the first type subband, the second subband resource indicator being determined based on the position of the starting subband resource group of the first type subband and the number of consecutive subband resource groups occupied by the first type subband.

[0172] In one example, the first type subband is an uplink subband, or the first type subband is a downlink subband, and the decision module 42 further...

The transmitting module is further used, if the subband resource group is a subband resource group that includes a downlink subband resource and a guard subband resource, to either receive downlink data in the downlink subband resource of the subband resource group or to prohibit the reception of downlink data in the downlink subband resource of the subband resource group.

The determination module 42 is further used to determine all SBFD symbols for setting the first type subband, based on the start symbol and length of the SBFD symbols.

[0175] In one example, the starting symbol of the SBFD symbol represents the first symbol in the frame structure of the SBFD symbol, and the length of the SBFD symbol represents the number of symbols following the starting symbol, or the starting symbol of the SBFD symbol represents the last symbol in the frame structure of the SBFD symbol, and the length of the SBFD symbol represents the number of symbols following the starting symbol.

[0176] If the frame structure configuration message is a semi-static frame structure configuration message, the frame structure configuration message is either TDD-UL-DL-ConfigCommon or TDD-UL-DL-ConfigDedicated in the RRC message.
