Description

Method, device and equipment for determining sub-band resources Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, apparatus, and device for determining sub-band resources. Background Art

[0002] The TDD (Time Division Duplex) system is widely used in mobile communication systems, such as the 5G system. In the TDD system, the frame structure can be divided into DL (Downlink) time slots, UL (Uplink) time slots, and flexible time slots.

[0003] A DL time slot includes multiple DL symbols, and downlink data is processed in the frequency domain resources corresponding to these DL symbols. A UL time slot includes multiple UL symbols, and uplink data is processed in the frequency domain resources corresponding to these UL symbols. A flexible time slot includes at least one F (Flexible) symbol. The F symbol can be used for DL, i.e., downlink data is processed in the frequency domain resources corresponding to the F symbol. The F symbol can also be used for UL, i.e., uplink data is processed in the frequency domain resources corresponding to the F symbol. The F symbol can also be used for a GP (Guard Period), i.e., the frequency domain resources corresponding to the F symbol are used to protect uplink and downlink switching.

[0004] The TDD system may operate in HD (Half Duplex) mode, that is, at the same time, the same frequency domain resources may only be used for UL or DL.

[0033] The terms used in the embodiments of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The singular forms "a," "the," and "the" used in this application and claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to any or all possible combinations of one or more associated listed items.

[0034] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present application, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" used may also be interpreted as "at the time of" or "when" or "in response to determining".

[0035] TDD systems can operate in HD mode, meaning that the same frequency domain resources can only be used for UL or DL ​​at the same time. To make more flexible use of frequency domain resources and improve resource utilization, TDD systems can also operate in FD (Full-Duplex) mode, meaning that the same frequency domain resources are used for both UL and DL at the same time, that is, uplink and downlink data can be processed simultaneously on the same frequency domain resources.

[0036] In a TDD system, the frame structure is divided into DL time slots, UL time slots, and flexible time slots. Once the frame structure is determined, the UE can transmit and receive data according to the frame structure. For UEs using HD (Half Duplex) mode, the base station (such as the gNB) schedules the UE to transmit or receive according to the frame structure. For UEs using FD mode, the base station schedules the UE to transmit, receive, or both according to the frame structure. In summary, the base station can configure the frame structure and notify the UE of the frame structure so that the UE understands the frame structure and can correctly transmit and receive data. Furthermore, knowing the frame structure allows the UE to be aware of potential inter-UE interference and use interference cancellation techniques to mitigate interference and improve communication reliability.

[0037] For example, in a TDD system, for a frame structure that is primarily used for uplink transmission, more UL time slots are usually configured. This results in fewer DL time slots, which in turn limits the downlink transmission rate and increases the transmission delay of downlink data, resulting in a longer downlink transmission delay and the non-utilization of downlink services.

[0038] In one example of the present application, a subband resource determination method is proposed, which configures flexible downlink subband resources and uplink subband resources for the UE in the BWP. For example, it is possible to configure uplink subband resources using downlink time slots or flexible time slots, and transmit uplink data using the uplink subband resources. Transmitting uplink data using downlink time slots or flexible time slots can improve the uplink transmission rate and reduce the transmission delay of uplink data. In addition, it is also possible to configure downlink subband resources using uplink time slots or flexible time slots, and transmit downlink data using downlink subband resources. Transmitting downlink data using uplink time slots or flexible time slots can improve the downlink transmission rate and reduce the transmission delay of downlink data.

[0039] In one example of the present application, a method for determining subband resources is proposed. The method can be applied to a UE. FIG1A is a flow chart of the method for determining subband resources. The method may include:

[0040] Step 111: Receive a subband resource indication message sent by a base station. The subband resource indication message may include frequency domain resource information of a first type of subband. The first type of subband may be an uplink subband or a downlink subband.

[0041] Step 112: Determine the starting position and / or ending position of the first-class subband based on the frequency domain resources of the first-class subband indicated by the frequency domain resource information of the first-class subband, and determine the starting position or ending position of the protection subband through the starting position and / or ending position of the first-class subband.

[0042] Step 113: Receive a protection subband configuration message sent by the base station. The protection subband configuration message may include the length of the protection subband, such as the number of PRBs occupied by the protection subband.

[0043] Step 114: Determine the guard subband resources from the BWP using the starting position of the guard subband and the length of the guard subband, or determine the guard subband resources from the BWP based on the ending position of the guard subband and the length of the guard subband.

[0044] The BWP is used to configure SBFD frequency domain resources (i.e., SBFD subband resources). SBFD subband resources can include uplink and downlink subband resources. Therefore, the BWP is used to configure uplink and downlink subband resources. Of course, the BWP can also be used to configure guard subband resources (which are not SBFD subband resources). Therefore, the guard subband resources can be determined from the BWP.

[0045] In one example of the present application, a method for determining subband resources is proposed. The method can be applied to a base station. FIG1B is a flow chart of the method for determining subband resources. The method may include:

[0046] Step 121: Send a subband resource indication message to the UE, where the subband resource indication message includes frequency domain resource information of the first-class subband. The subband resource indication message is used to instruct the UE to determine the starting position and / or ending position of the first-class subband based on the frequency domain resources of the first-class subband indicated by the frequency domain resource information, and to determine the starting position or ending position of the guard subband based on the starting position and / or ending position of the first-class subband.

[0047] Step 122: Send a guard subband configuration message to the UE, where the guard subband configuration message includes the guard subband length. The configuration message instructs the UE to determine the guard subband resources from the BWP using the guard subband start position and the guard subband length, or to determine the guard subband resources from the BWP based on the guard subband end position and the guard subband length.

[0048] In one example, the configuration message for the guard subband may be a semi-static configuration message. The base station may send the semi-static configuration message to the UE, and the UE may receive the semi-static configuration message sent by the base station. The semi-static configuration message includes the length of the guard subband, that is, the UE may obtain the length of the guard subband from the semi-static configuration message.

[0049] In one example, the configuration message for the protection subband can be a semi-static configuration message and a dynamic configuration message. The base station can send the semi-static configuration message to the UE, and the UE can receive the semi-static configuration message sent by the base station. The semi-static configuration message includes a subband length list, and the subband length list can include the lengths of multiple protection subbands. Then, the base station can send a dynamic configuration message to the UE, and the UE can receive the dynamic configuration message sent by the base station. The dynamic configuration message includes index information, and the index information is used to indicate the length of a protection subband corresponding to the index information selected from the subband length list. In this case, the UE can obtain the index information from the dynamic configuration message and obtain the length of the protection subband based on the index information.

[0050] In one example, the UE determines the starting position or ending position of the guard subband based on the starting position and / or ending position of the first-class subband. This may include: if the first-class subband is located at the upper boundary of the BWP, determining the ending position of the guard subband based on the starting position of the first-class subband. Alternatively, if the first-class subband is located at the lower boundary of the BWP, determining the starting position of the guard subband based on the ending position of the first-class subband. Alternatively, if the first-class subband is located in the middle of the BWP, determining the starting position of the guard subband above the first-class subband based on the ending position of the first-class subband, and determining the ending position of the guard subband below the first-class subband based on the starting position of the first-class subband.

[0051] In one example, the frequency domain resource information of the first type of subband may include a bitmap configuration of a subband resource group occupied by the first type of subband. If the bitmap configuration indicates that the subband resource group corresponds to a first value, then the subband resource group is occupied by the first type of subband. If the bitmap configuration indicates that the subband resource group corresponds to a second value, then the subband resource group is not occupied by the first type of subband. In this case, the UE may determine the frequency domain resources occupied by the first type of subband based on the bitmap configuration of the subband resource group occupied by the first type of subband. The first value and the second value may be configured based on experience, such as the first value being 1 and the second value being 0.

[0052] In one example, the frequency-domain resource information of the first-category subband may include a first-category subband resource indicator value corresponding to the first-category subband, where the first-category subband resource indicator value is determined by the starting physical resource block position of the first-category subband and the number of consecutive physical resource blocks occupied by the first-category subband. In this case, the UE may derive the starting physical resource block position of the first-category subband and the number of consecutive physical resource blocks occupied by the first-category subband based on the first-category subband resource indicator value, and then determine the frequency-domain resources occupied by the first-category subband based on the starting physical resource block position of the first-category subband and the number of consecutive physical resource blocks occupied by the first-category subband.

[0053]

[0054] A subband resource indicator value, PRB Start Based on the above formula, when the first subband resource indicator value SBRIV is known, the UE can deduce the starting physical resource block position of the first subband and the number of consecutive physical resource blocks occupied by the first subband.

[0055] In one example, the frequency-domain resource information of the first-category subband may include a second-subband resource indicator value corresponding to the first-category subband, where the second-subband resource indicator value is determined by the starting subband resource group position of the first-category subband and the number of consecutive subband resource groups occupied by the first-category subband. In this case, the UE may derive the starting subband resource group position of the first-category subband and the number of consecutive subband resource groups occupied by the first-category subband based on the second subband resource indicator value, and then determine the frequency-domain resources occupied by the first-category subband based on the starting subband resource group position of the first-category subband and the number of consecutive subband resource groups occupied by the first-category subband.

[0056] The process of obtaining the second subband resource indication value includes: The second subband resource indicator value is determined in the following manner: SBRIV = N SBG *(L SBG -1)+SBG start Otherwise, the second subband resource indicator value is determined as follows: SBRIV = N SBG *(N SBG -L SBG +1)+(N SBG -1-SBG start ). Among them, L SBG Indicates the number of consecutive subband resource groups occupied by the first type of subband, N SBG Indicates the total number of subband resource groups in the BWP where the first subband is located, SBRIV indicates the second subband resource indicator value, SBG start Based on the above formula, when the second subband resource indicator value SBRIV is known, the UE can deduce the starting subband resource group position of the first type of subband and the number of consecutive subband resource groups occupied by the first type of subband.

[0057] In one example, before sending the subband resource indication message to the UE, the base station may also send a subband configuration type indication message to the UE, and the UE may receive the subband configuration type indication message sent by the base station. If the subband configuration type indication message indicates a bitmap type, this indicates that the subband resource indication message carries the bitmap configuration of the subband resource group occupied by the first type of subband. That is, the UE determines the frequency domain resources occupied by the first type of subband based on the bitmap configuration of the subband resource group occupied by the first type of subband.

[0058] Alternatively, if the subband configuration type indication message is used to indicate the SBRIV type, it means that the subband resource indication message carries the first subband resource indication value corresponding to the first type of subband, that is, the UE can parse the first subband resource indication value SBRIV and derive the starting physical resource block position of the first type of subband and the number of consecutive physical resource blocks occupied by the first type of subband based on the first subband resource indication value SBRIV.

[0059] Alternatively, if the subband configuration type indication message is used to indicate the SBRIV and SBG types, it means that the subband resource indication message carries the second subband resource indication value corresponding to the first type of subband, that is, the UE can parse the second subband resource indication value SBRIV and derive the starting subband resource group position of the first type of subband and the number of continuous subband resource groups occupied by the first type of subband based on the second subband resource indication value SBRIV.

[0060] In one example, after the UE determines the protected subband resources from the BWP, if the frequency domain resources of the first-category subband are uplink subband resources, the UE determines the downlink subband resources from the BWP based on the uplink subband resources and the protected subband resources. If the frequency domain resources of the first-category subband are downlink subband resources, the UE determines the uplink subband resources from the BWP based on the downlink subband resources and the protected subband resources.

[0061] In one example, a BWP may include multiple subband resource groups. After the UE determines the protection subband resources from the BWP, if the subband resource group is a frequency-domain resource group that includes uplink subband resources and protection subband resources, the UE transmits uplink data on the uplink subband resources of the subband resource group, or prohibits transmitting uplink data on the uplink subband resources of the subband resource group. If the subband resource group is a subband resource group that includes downlink subband resources and protection subband resources, the UE receives downlink data on the downlink subband resources of the subband resource group, or prohibits receiving downlink data on the downlink subband resources of the subband resource group.

[0062] In one example, the first type of subband may be a frequency domain resource configured on an SBFD symbol. The base station may send a frame structure configuration message to the UE, and the UE may receive the frame structure configuration message sent by the base station, where the frame structure configuration message includes the start symbol of the SBFD symbol and the length of the SBFD symbol. The frame structure configuration message may be a semi-static frame structure configuration message. If the frame structure configuration message is a semi-static frame structure configuration message, the frame structure configuration message is TDD-UL-DL-ConfigCommon (common configuration) or TDD-UL-DL-ConfigDedicated (dedicated configuration) in the RRC message.

[0063] The SBFD symbol start symbol and SBFD symbol length are used to determine the total number of SBFD symbols used to configure the first type of subband. For example, the SBFD symbol start symbol indicates the first SBFD symbol in the frame structure, and the SBFD symbol length indicates the number of symbols from the start symbol forward. Alternatively, the SBFD symbol start symbol indicates the last SBFD symbol in the frame structure, and the SBFD symbol length indicates the number of symbols from the start symbol forward.

[0064] In one example, the first type of subband may be a frequency domain resource configured on an SBFD symbol. The base station sends an RRC message to the UE, and the UE receives the RRC message sent by the base station. The RRC message includes multiple time slot format combinations, each time slot format combination including a time slot format type indicating that the SBFD symbol is included.

[0065] The base station may send a DCI message to the UE, and the UE receives the DCI message sent by the base station. The DCI message includes an index of a target time slot format combination. After receiving the DCI message, the UE selects a corresponding target time slot format combination from multiple time slot format combinations based on the index of the target time slot format combination. Based on the target time slot format combination, the UE determines all SBFD symbols used to configure the first type of subband.

[0066] As can be seen from the above technical solution, the UE determines the starting or ending position of the protection subband based on the subband resource indication message. Based on the protection subband configuration message, the UE determines the length of the protection subband, identifies the protection subband resources from the BWP, and distinguishes between uplink subband resources, downlink subband resources, and protection subband resources within the BWP. The UE uses SBFD subband resources (SBFD subband resources include uplink subband resources and downlink subband resources) for data transmission, improving resource utilization, enhancing network coverage and capacity, and reducing transmission delay.

[0067] The above technical solution of the present application is described below with reference to examples.

[0068] In a TDD system, the frame structure is divided into UL slots, DL slots, and flexible slots (F slots) according to the time slots. The symbols in the flexible slots can be configured as UL symbols, DL symbols, and F symbols. F symbols can be used for UL, DL, or GP. Among them, uplink data can be transmitted in the UL slots, UL symbols in the flexible slots, or F symbols. Uplink data cannot be transmitted in the DL slots or DL ​​symbols in the flexible slots. Downlink data can be transmitted in the DL slots, DL symbols in the flexible slots, or F symbols. Downlink data cannot be transmitted in the UL slots or UL symbols in the flexible slots.

[0069] Full-duplex communication can be achieved through SBFD. This means that SBFD subband resources (frequency domain resources) can be configured within a BandWidth Part (BWP). SBFD subband resources can include uplink and downlink subband resources. This allows data to be transmitted in different directions than other frequency domain resources at the same time on these SBFD subband resources. For example, SBFD subband resources can be configured within a BWP within a DL time slot, and uplink data can be transmitted via the SBFD subband resources, allowing uplink data to be transmitted within the DL time slot. SBFD subband resources can also be configured within a BWP within a DL symbol within a flexible time slot, and uplink data can be transmitted via the SBFD subband resources, allowing uplink data to be transmitted within the DL symbol within the flexible time slot.

[0070] SBFD subband resources are configured in the BWP of the UL time slot, and downlink data is transmitted through the SBFD subband resources, so that the downlink data is transmitted in the UL time slot. SBFD subband resources are configured in the BWP of the UL symbol of the flexible time slot, and downlink data is transmitted through the SBFD subband resources, so that the downlink data is transmitted in the UL symbol of the flexible time slot.

[0071] In one example, the SBFD sub-band resources may be frequency domain resources in an SBFD time slot or an SBFD symbol. The SBFD symbol may be defined as a symbol of an SBFD sub-band. On the SBFD sub-band of these SBFD symbols, the base station and the UE may perform full-duplex communication. That is, uplink transmission, downlink transmission, or simultaneous uplink and downlink transmission may be performed on the SBFD sub-band resources.

[0072] SBFD subband resources can be explicitly designated as uplink, downlink, or flexible. When a SBFD subband resource is designated as flexible, uplink or downlink scheduling can be flexibly performed on the SBFD subband resource. If no SBFD subband resource is explicitly designated as flexible, it can be used for uplink or downlink data transmission. SBFD symbol configuration includes the following: which symbols in the DL time slot, UL time slot, and F time slot are used for SBFD transmission, as well as the implementation period and starting point.

[0073] SBFD subband resources indicated as uplink are called uplink subband resources, abbreviated as UL SB, meaning they are used for uplink. SBFD subband resources indicated as downlink are called downlink subband resources, abbreviated as DL SB, meaning they are used for downlink. Frequency domain resources indicated as guard subbands are called guard subband resources, abbreviated as GB, meaning they are used for guard subbands.

[0074] For a half-duplex UE supporting the SBFD function, the UE can obtain configurations related to SBFD subband resources. However, the UE can only receive DL data or send UL data at the same time (symbol).

[0075] The base station configures SBFD subband resources for half-duplex UEs that support the SBFD function. SBFD subband resources are configured for the UE in DL time slots or DL ​​symbols. These SBFD subband resources are used to transmit UL data, meaning they can be uplink subband resources. DL symbols configured with SBFD subband resources are SBFD symbols. In addition to the uplink subband resources, SBFD symbols contain downlink subband resources and guard subband resources, with the guard subband resources located between the uplink and downlink subband resources.

[0076] SBFD subband resources are configured for the UE in a UL timeslot or UL symbol, and are used to transmit DL data. This means the SBFD subband resources can be downlink subband resources. UL symbols configured with SBFD subband resources are SBFD symbols. In addition to the downlink subband resources, SBFD symbols contain uplink subband resources and guard subband resources, with the guard subband resources located between the uplink and downlink subband resources.

[0077] SBFD subband resources are configured for the UE in the F time slot or F symbol, and the SBFD subband resources are used to transmit DL data (or UL data). That is, the SBFD subband resources can be downlink subband resources (or uplink subband resources). F symbols configured with SBFD subband resources are SBFD symbols. In addition to the downlink subband resources (or uplink subband resources), the SBFD symbols contain uplink subband resources (or downlink subband resources) and guard subband resources. The guard subband resources are located between the uplink subband resources and the downlink subband resources.

[0078] In one example, the base station in the subsequent embodiments is a full-duplex base station that can process both DL and UL data. The UE in the subsequent embodiments is a half-duplex UE that supports the SBFD function and can only process either DL or UL data at a time and can obtain all SBFD configuration parameters.

[0079] To support FD communication, SBFD subband resources may be semi-statically configured, such as through RRC (Radio Resource Control) signaling, or dynamically configured, such as through DCI (Downlink Control Information).

[0080] The time domain resources of SBFD, that is, the frame structure of SBFD, can be configured through semi-static configuration or semi-static configuration plus dynamic indication. Dynamic indication can also change SBFD symbols.

[0081] First, protect the configuration of sub-band resources.

[0082] When configuring downlink sub-band resources and uplink sub-band resources in the BWP, it is necessary to configure a protection bandwidth (i.e., protection sub-band resources) between the downlink sub-band resources and the uplink sub-band resources. By protecting the sub-band resources, the interference between the sub-bands can be reduced, that is, the protection sub-band resources need to be configured in the BWP.

[0083] For example, uplink subband resources (UL SB) and guard subband resources (GB) can be configured on the BWP, and then the downlink subband resources (DL SB) can be implicitly derived, that is, the remaining resources in the BWP except the uplink subband resources and guard subband resources are downlink subband resources.

[0084] For another example, downlink subband resources and protection subband resources can be configured on the BWP. Based on the downlink subband resources and protection subband resources, the uplink subband resources can be implicitly derived, that is, the remaining resources in the BWP except the downlink subband resources and protection subband resources are uplink subband resources.

[0085] For another example, uplink subband resources and downlink subband resources can be configured on the BWP. Based on the uplink subband resources and downlink subband resources, the protection subband resources can be implicitly derived, that is, the remaining resources in the BWP except the uplink subband resources and downlink subband resources are protection subband resources.

[0086] In one example, the frequency domain resources and protection subband resources of the first subband can be configured, and then the frequency domain resources of the second subband can be implicitly derived, that is, the frequency domain resources and protection subband resources of the first subband are explicitly configured. The frequency domain resources of the first subband can be uplink subband resources, and the frequency domain resources of the second subband can be downlink subband resources, that is, the uplink subband resources and protection subband resources are explicitly configured. Alternatively, the frequency domain resources of the first subband can be downlink subband resources, and the frequency domain resources of the second subband can be uplink subband resources, that is, the downlink subband resources and protection subband resources are explicitly configured.

[0087] In an example, to explicitly configure protected subband resources, you can use the following method:

[0088] The base station indicates the uplink subband resources by removing the total number of PRBs occupied by the uplink subband resources and their specific frequency domain locations, as well as the total number of PRBs occupied by the protection subband resources and their specific frequency domain locations from the BWP. The remaining number is the total number of PRBs occupied by the downlink subband resources and their specific frequency domain locations. In this case, the protection subband resources can be explicitly indicated or set to 0. There are two ways to indicate the frequency domain resources of the protection subband resources: indicating the starting PRB and the total number of occupied frequency domain resources (M*N), as shown in Table 1, which is the first way to indicate the frequency domain resources of the protection subband resources; or calculating the total number of occupied protection subband resources based on the start and end positions of the frequency domain resources, as shown in Table 2, which is the second way to indicate the frequency domain resources of the protection subband resources.

[0089] Table 1

[0090] Table 2

[0091] The first indication method of frequency domain resources for protected sub-band resources is to protect sub-band resources through starting position, frequency domain resource allocation indication and frequency domain resource unit indication. Assume that the number of PRBs in BWP is N PRB , the starting position needs log2(N PRB ) bits of data, the optional number of frequency domain resource unit indication (P) is N, which requires log2(N) bits. The frequency domain resource allocation indication is the number of frequency domain resource PRBs divided by the frequency domain resource unit indication, and then rounded up, that is, ceil(N PRB / P) bits. Taking 100MHz bandwidth as an example, that is, 273 PRBs, 5 optional frequency domain resource units in Table 1, P = 16PRB as an example, log2(N PRB )+log2(N)+ceil(N PRB / P) = 9 + 18 + 3 = 30 bits. If the uplink sub-band resource is located in the middle of the BWP, two protection bandwidths are required between the uplink sub-band resource and the downlink sub-band resource, that is, 60 bits are required.

[0092] The second indication method of the frequency domain resources for the protection subband resources adopts the representation method of the starting position and the ending position, assuming that the number of PRBs in the BWP is N PRB The starting and ending positions need to be clearly indicated. A protection bandwidth requires 2*log2(N PRB ) bits. Taking 100MHz bandwidth as an example, a single guard bandwidth requires 18 bits. If the uplink subband resource is located in the middle of the BWP, two guard bandwidths are required between the uplink subband resource and the downlink subband resource, that is, 36 bits are required.

[0093] Regardless of the first indication method or the second indication method, the protection sub-band resources require more bits to indicate, which will greatly increase the signaling overhead and thus reduce the data transmission rate.

[0094] In response to the above findings, to explicitly configure the protection subband resources, the following method can be used: the base station sends a protection subband configuration message to the UE, and the UE receives the protection subband configuration message, where the protection subband configuration message includes the length of the protection subband. The UE can use the starting position and / or ending position of the first-category subband to determine the starting position or ending position of the protection subband, and then use the starting position and length of the protection subband to determine the protection subband resources from the BWP. Alternatively, the UE can determine the protection subband resources from the BWP based on the ending position and length of the protection subband.

[0095] For example, when explicit configuration of guard subband resources is required, this can be achieved through semi-static or dynamic configuration, and the guard subband resources can be configured together with the frequency domain resources of the first type of subband (such as uplink subband resources). The length of the guard subband can be flexibly configured based on the actual scenario. For example, in an environment with large frequency selective fading, a longer guard bandwidth can be configured as much as possible to reduce inter-subband interference. By explicitly configuring guard subband resources, the needs of different service scenarios can be met.

[0096] When semi-static configuration is used, the protection subband configuration message can be a semi-static configuration message. That is, the protection subband resources are configured to the UE via a semi-static configuration message (such as an RRC message). The base station can select the protection subband length from a set of optional lengths and then send the protection subband length to the UE via an RRC message. The UE then determines the protection subband length from the RRC message based on the agreement between the base station and the UE.

[0097] For example, the length of the guard subband can be {1, 2, 3, 4, 5, 6, 7, 8, 16}. Alternatively, only typical values, such as {1, 2, 4, 6, 8}, can be configured. These are just a few examples of possible lengths and are not limiting. The length of the guard subband can be set arbitrarily. The guard subband length is optional. If not configured, dynamic scheduling by the base station ensures the guard bandwidth between the UL and DL.

[0098] An example of configuring parameters for an RRC message is as follows:

[0099] guardBandSizeInSbfd enumerate{1,2,3,4,5,6,7,8},optional

[0100] For example, the base station may select a value from {1, 2, 3, 4, 5, 6, 7, 8} as the length of the guard subband, and the base station may send the length of the guard subband to the UE through the RRC message.

[0101] When dynamic configuration is adopted, the configuration message of the protection subband may be a semi-static configuration message and a dynamic configuration message. The semi-static configuration message may be an RRC message, and the dynamic configuration message may be a DCI message.

[0102] The base station can send an RRC message to the UE, and send an optional protection bandwidth list (also called a subband length list) to the UE through the RRC message. The protection bandwidth list can include the lengths of multiple protection subbands. An example of the protection bandwidth list is as follows: sbfdGuardBandList sequence{1,2,3,4,5,6,7,8}, that is, the lengths of multiple protection subbands can be {1,2,3,4,5,6,7,8} respectively, and there is no restriction on this.

[0103] Then, the base station can send a DCI message to the UE. The base station sends the protection bandwidth indication to the UE through the DCI message. The protection bandwidth indication is an index information, and the index information is used to indicate the index value of the protection bandwidth list, that is, the length of the first protection subband in the protection bandwidth list.

[0104] Among them, the size of the protection bandwidth indication is log2(sizeof(sbfdGuardBandList)). Referring to the protection bandwidth list above, the bit size occupied by the protection bandwidth indication is log2(8)=3 bits, 0 corresponds to the first value in the protection bandwidth list, 1 corresponds to the second value in the protection bandwidth list, and so on.

[0105] A new parameter may be additionally introduced into the DCI message, and the new parameter is used to represent the protection bandwidth indication. For example, an example of the protection bandwidth indication is as follows: sbfdGuardBandIndicator.

[0106] Based on the guard bandwidth indication in the DCI message, the UE may select the length of the guard subband corresponding to the guard bandwidth indication from the subband length list, that is, obtain the length of the guard subband.

[0107] In an example, the protection subband resources are configured to be of a fixed size and are adjacent to the frequency domain resources of the first type of subband (such as uplink subband resources or downlink subband resources). In addition to the frequency domain resources and protection subband resources of the first type of subband, the remaining part is the frequency domain resources of the second type of subband (such as downlink subband resources or uplink subband resources). The number of protection subband resources is determined according to the position of the frequency domain resources of the first type of subband.

[0108] For example, if the frequency domain resources of the first-class subband are located in the middle of the BWP, there are two guard subband resources, one located between the frequency domain resources of the first-class subband and the frequency domain resources of the second-class subband on both sides. If the frequency domain resources of the first-class subband are located at one end of the BWP, there is only one guard subband resource, and the guard subband resource is located between the frequency domain resources of the first-class subband and the frequency domain resources of the second-class subband.

[0109] If the frequency domain resources of the first type of subband are not configured starting from the BWP edge, and the number of PRBs between the BWP edge and the nearest PRB in the frequency domain resources of the first type of subband is less than the number of protection subband resources, then there are no frequency domain resources of the second type of subband between the BWP edge and the frequency domain resources of the first type of subband.

[0110] In an example, the UE can determine the starting position or ending position of the protection subband by the starting position and / or ending position of the first type of subband, and then use the starting position of the protection subband and the length of the protection subband to determine the protection subband resources from the BWP, or use the ending position of the protection subband and the length of the protection subband to determine the protection subband resources from the BWP.

[0111] If the first-class subband is located at the upper boundary of the BWP, the UE can determine the end position of the guard subband based on the start position of the first-class subband. Alternatively, if the first-class subband is located at the lower boundary of the BWP, the UE can determine the start position of the guard subband based on the end position of the first-class subband. Alternatively, if the first-class subband is located in the middle of the BWP, the UE can determine the start position of the guard subband above the first-class subband based on the end position of the first-class subband, and determine the end position of the guard subband below the first-class subband based on the start position of the first-class subband.

[0112] After the UE determines the protected subband resources, it can determine the frequency domain resources of the second type of subband from the BWP based on the frequency domain resources of the first type of subband and the protected subband resources. For example, if the frequency domain resources of the first type of subband are uplink subband resources, the downlink subband resources are determined from the BWP based on the uplink subband resources and the protected subband resources. If the frequency domain resources of the first type of subband are downlink subband resources, the uplink subband resources are determined from the BWP based on the downlink subband resources and the protected subband resources.

[0113] The frequency domain resource unit indication may be used to determine the granularity of the frequency domain resource group of the subband. The frequency domain resource group of the subband is also referred to as an SBG, and the granularity of the SBG may be equal to the RBG.

[0114] Taking the frequency domain resources of the first type of sub-band as uplink sub-band resources as an example, referring to Figure 2, a schematic diagram of the configuration of uplink sub-band resources and protection sub-band resources is given. The uplink sub-band resources are located in the middle of the BWP. The BWP can include 17 SBGs (Subband Groups, also known as sub-band resource granularity), and SBG is equal to RBG, that is, the BWP includes 17 RBGs, such as RBG0-RBG16 in Figure 2.

[0115] As shown in Figure 2, the size of an RBG is 8 PRBs. Due to the limitation of the total number of PRBs, the number of PRBs corresponding to the last RBG can be less than or equal to 8. For example, RBG0 corresponds to PRBs 0-7, RBG1 corresponds to PRBs 8-15, ..., and RBG16 corresponds to PRBs 128-132.

[0116] As shown in Figure 2, assuming the uplink subband resource is located in the middle of the BWP, there are two guard subband resources. One guard subband resource corresponds to RBG4, and the size of this guard subband resource is 4 PRBs. For example, this guard subband resource corresponds to PRBs 36-39, and this guard subband resource is located between the uplink subband resource and the downlink subband resource. Obviously, for this guard subband resource, the UE can determine the end position of the guard subband below the uplink subband resource (i.e., the 39th PRB) by the starting position of the uplink subband resource (i.e., the 40th PRB).

[0117] Another guard subband resource corresponds to RBG13. This guard subband resource is sized at 4 PRBs, such as PRBs 104-107, and is located between the uplink and downlink subband resources. Obviously, for this guard subband resource, the UE can determine the starting position of the guard subband above the uplink subband resource (i.e., the 104th PRB) by the ending position of the uplink subband resource (UL SB) (i.e., the 103rd PRB).

[0118] In one example, the guard subband resource size may be different from the RBG size, and the two may not be aligned. That is, an RBG may include both guard subband resources and uplink subband resources, that is, some PRBs are configured as guard subbands, and the remaining PRBs are configured as uplink subbands. Alternatively, an RBG may include both guard subband resources and downlink subband resources, that is, some PRBs are configured as guard subbands, and the remaining PRBs are configured as downlink subbands. In this case, if this RBG is not used during PDSCH scheduling, resources will be wasted, such as PRBs 36-39 and PRBs 104-107 in Figure 2, which will result in some resource waste.

[0119] To avoid resource waste, after the UE determines the protection subband resources from the BWP, if the subband resource group is a frequency domain resource group that includes uplink subband resources and protection subband resources, the UE may send uplink data on the uplink subband resources of the subband resource group, or the UE may prohibit sending uplink data on the uplink subband resources of the subband resource group. Alternatively, if the subband resource group is a subband resource group that includes downlink subband resources and protection subband resources, the UE may receive downlink data on the downlink subband resources of the subband resource group, or the UE may prohibit receiving downlink data on the downlink subband resources of the subband resource group.

[0120] For example, the following agreement is made between the base station and the UE: If the base station uses frequency domain resource allocation type 0 (FDRA0) when scheduling the UE, the RBGs occupied by the protected subband resources can still be indicated for use, but the RBG size becomes the RBG size minus the protected subband resource size. That is, for the UE, when making a PDSCH call, the RBG occupied by the protected subband resources is still indicated as 1, but both the base station and the UE believe that only a portion of the PRBs in the RBG that are not occupied by the protected subband resources are used. Accordingly, when calculating the PDSCH transport block size (TBS), the PRBs occupied by the protected subband resources in the RBG are removed.

[0121] If the base station adopts frequency domain resource allocation type 1 (FDRA1) when scheduling the UE, the RBGs occupied by the protected subband resources are not used, and the base station does not use the PRBs occupied by the protected subband resources when scheduling the PDSCH.

[0122] Second, the configuration of frequency domain resources of the first type of sub-band.

[0123] The base station may send a subband resource indication message to the UE, where the subband resource indication message includes frequency domain resource information of the first-category subband, so that the UE may determine the frequency domain resources of the first-category subband from the BWP based on the frequency domain resource information of the first-category subband. The first-category subband may be an uplink subband or a downlink subband, and the frequency domain resources of the first-category subband may be an uplink subband resource or a downlink subband resource.

[0124] In an example, the frequency domain resources of the first type of subband can be configured as follows:

[0125] Method 1: Subband configuration based on bit mapping.

[0126] When explicitly configuring the first-class subband and the protection subband, the first-class subband is configured using a bitmap scheme, which is called a bitmap scheme. In order to save the number of bits, the frequency domain resource unit indication can be used to determine the frequency domain resource granularity of the subband. The frequency domain resource granularity of the subband is also called the subband resource group (SBG). The granularity of the SBG can be equal to the RBG. After determining the SBG, the number of bits occupied by the subband resource allocation indication (Bitmap) is determined according to the size of the BWP, that is, Indicates the size of BWP, that is, the number of PRBs. If it cannot be divided by SBG, then the frequency domain resource indicated by the last bit will be smaller than SBG, and its size is

[0127] Then, the resources occupied by the first type of subband are determined using the Bitmap. The "1" in the Bitmap is used to indicate that the corresponding frequency domain resources in the SBG are allocated to the frequency domain resources of the first type of subband, and the "0" in the Bitmap is used to indicate that the corresponding frequency domain resources in the SBG are not allocated to the frequency domain resources of the first type of subband.

[0128] As shown in Figure 2, taking the first type of subband as an uplink subband as an example, the uplink subband is located in the middle of the BWP, the SBG is equal to 8, the size of the guard subband is 4 PRBs, there are two guard subbands located between the uplink subband and the downlink subbands on both sides, and the subband resource allocation indication bitmap is configured as 00000111111110000.

[0129] In summary, the frequency domain resource information for the first-class subband may include a bitmap configuration of the subband resource group occupied by the first-class subband. If the bitmap configuration indicates that the subband resource group corresponds to a first value (e.g., 1), then the subband resource group is occupied by the first-class subband. If the bitmap configuration indicates that the subband resource group corresponds to a second value (e.g., 0), then the subband resource group is not occupied by the first-class subband. In this case, the UE determines the frequency domain resources occupied by the first-class subband based on the bitmap configuration of the subband resource group occupied by the first-class subband.

[0130] In one example, when implicitly configuring protected subband resources, that is, explicitly configuring uplink and downlink subband resources, and deriving protected subband resources based on the uplink and downlink subband resources, bitmaps need to be configured for both uplink and downlink subband resources. If bitmaps are used to indicate uplink and downlink subband resources, the size of the protected subband resources is an integer multiple of the RBG.

[0131] Method 2: Subband configuration based on subband resource indication value.

[0132] When the first type of subband is explicitly configured, the first type of subband is determined by the subband resource indication value (SBRIV) consisting of the starting position and length. This scheme is called the SBRIV scheme. Among them, SBRIV can be determined by the starting PRB position RB of the first type of subband. Start and the number of consecutive PRBs occupied by the first type of subband L RB To determine the starting PRB position RB of the first type of subband Start Also known as PRB Start , the number of consecutive PRBs occupied by the first type of subband L RB Also denoted as L PRB .

[0133] In summary, the frequency domain resource information of the first type of sub-band may include the sub-band resource indication value SBRIV corresponding to the first type of sub-band (for the convenience of distinction, it can be recorded as the first sub-band resource indication value), and the first sub-band resource indication value is the starting physical resource block position PRB of the first type of sub-band. Start and the number of consecutive physical resource blocks occupied by the first type of subband L PRB In this case, the UE can derive the starting physical resource block position PRB of the first type of subband based on the first subband resource indicator value SBRIV Start and the number of consecutive physical resource blocks occupied by the first type of subband L PRB , and then determine the frequency domain resources occupied by the first type of subband based on the starting physical resource block position of the first type of subband and the number of consecutive physical resource blocks occupied by the first type of subband.

[0134]

[0135] in, Indicates the total number of physical resource blocks in the BWP where the first type of subband is located, that is, the number of PRBs in the BWP where the first type of subband is located, L PRB ≥1 and cannot exceed

[0136] In an example, taking the uplink subband as the first type of subband, when explicitly configuring the protection subband resources, the protection subband resources are adjacent to the uplink subband resources (learned through SBRIV). In the entire BWP, except for the uplink subband resources and the protection subband resources, the remaining resources are downlink subband resources.

[0137] In one example, if the subband resource indication message is configured semi-statically, the subband resource indication message may be an RRC message, which indicates the uplink subband resource by introducing a new parameter in the RRC message. For example, the new parameter may be ulSubband, and the bit size thereof is If there are a maximum of several uplink sub-band resources in the BWP, several of the above parameters need to be configured.

[0138] As shown in FIG2 , the size of the protection subband resource is 4, there is only one uplink subband resource, and the length of the uplink subband resource is 64 PRBs, and the starting position is 40. The RRC message can be shown in Table 3.

[0139] Table 3

[0140] In an example, if the sub-band resource indication message is dynamically configured, the sub-band resource indication message may be a DCI message. An example of the DCI message may be shown in Table 4.

[0141] Table 4

[0142] In one example, when implicitly configuring protected subband resources, that is, explicitly configuring uplink and downlink subband resources, in addition to introducing ulSubband, additional configuration parameters for downlink subband resources, such as dlSubband, are required. The number of parameters required depends on the number of downlink subband resources.

[0143] Mode 3: Subband configuration based on a subband resource indicator value and a subband resource group.

[0144] When explicitly configuring the first type of subband, you can use SBG as the unit for configuration. SBRIV is determined by the starting SBG position of the first type of subband. Start and the number of consecutive SBGs occupied by the first type of subband L SBG The scheme is called SBRIV+SBG scheme, and the first type of subband is determined by the subband resource indication value (SBRIV: Subband Resource Indication Value) composed of the starting SBG position and the number of SBGs.

[0145] In summary, the frequency domain resource information of the first type of sub-band may include the sub-band resource indicator value SBRIV corresponding to the first type of sub-band (for the convenience of distinction, it can be recorded as the second sub-band resource indicator value), and the second sub-band resource indicator value is the starting sub-band resource group position SBG of the first type of sub-band. Start and the number of consecutive subband resource groups occupied by the first type of subband L SBG In this case, the UE can derive the starting subband resource group position SBG of the first type of subband based on the second subband resource indicator value SBRIV Start and the number of consecutive subband resource groups occupied by the first type of subband L SBG, and then determining the frequency domain resources occupied by the first type of subband based on the starting subband resource group position of the first type of subband and the number of consecutive subband resource groups occupied by the first type of subband.

[0146] The process of obtaining the second subband resource indication value may include: if The following method is used

[0147]

[0148] In an example, taking the uplink subband as the first type of subband, when explicitly configuring the protection subband resources, the protection subband resources are adjacent to the uplink subband resources (learned through SBRIV). In the entire BWP, except for the uplink subband resources and the protection subband resources, the remaining resources are downlink subband resources.

[0149] In one example, if the subband resource indication message is configured semi-statically, the subband resource indication message may be an RRC message, which indicates the uplink subband resource by introducing a new parameter in the RRC message. For example, the new parameter may be ulSubband, and the bit size occupied by the ulSubband parameter is Depending on the maximum number of uplink sub-band resources in the BWP, several of the above parameters need to be configured.

[0150]

[0151] Table 5

[0152] In an example, if the sub-band resource indication message is dynamically configured, the sub-band resource indication message may be a DCI message. An example of the DCI message may be shown in Table 6.

[0153] Table 6

[0154] From the parameter sizes of Mode 2 and Mode 3, it can be seen that when the SBRIV+SBG solution is adopted, the required signaling overhead is much smaller than that of the SBRIV solution, thereby saving signaling overhead.

[0155] In one example, when implicitly configuring protected subband resources, that is, explicitly configuring uplink and downlink subband resources, in addition to introducing ulSubband, additional configuration parameters for downlink subband resources, such as dlSubband, are required. The number of parameters required depends on the number of downlink subband resources.

[0156] In one example, the base station can inform the UE in advance of the method used to configure the frequency domain resources of the first-category subband. This allows the UE to determine the frequency domain resources of the first-category subband based on the correct resource allocation method, and then determine the protected subband resources and the frequency domain resources of the second-category subband. For example, before sending the subband resource indication message to the UE, the base station may also send a subband configuration type indication message to the UE. The subband configuration type indication message may be an RRC message or another type of message.

[0157] If the subband configuration type indication message is used to indicate the bitmap type, it means that the subband resource indication message carries the bitmap configuration of the subband resource group occupied by the first type of subband. The UE determines the frequency domain resources occupied by the first type of subband based on the bitmap configuration, that is, adopts method 1 to determine the frequency domain resources occupied by the first type of subband.

[0158] Alternatively, if the subband configuration type indication message is used to indicate the SBRIV type, it means that the subband resource indication message carries the first subband resource indication value corresponding to the first type of subband. The UE can parse the first subband resource indication value SBRIV and determine the frequency domain resources occupied by the first type of subband based on the first subband resource indication value SBRIV, that is, use method 2 to determine the frequency domain resources occupied by the first type of subband.

[0159] Alternatively, if the subband configuration type indication message is used to indicate SBRIV and SBG types, it means that the subband resource indication message carries the second subband resource indication value corresponding to the first type of subband. The UE can parse the second subband resource indication value SBRIV and determine the frequency domain resources occupied by the first type of subband based on the second subband resource indication value SBRIV, that is, use method 3 to determine the frequency domain resources occupied by the first type of subband.

[0160] An example of a subband configuration type indication message (RRC message) may be: sbfdFdraType Enumerate{Type0, Type1, Type2}OPTIONAL. Type0 represents the Bitmap type, Type1 represents the SBRIV type, and Type2 represents both SBRIV and SBG types. For example, the parameter sbfdFdraType Enumerate is configured when SBFD is enabled and is not configured when SBFD is disabled.

[0161] Third, the configuration of SBFD symbols. SBFD subband resources can be frequency domain resources configured on SBFD symbols. To configure SBFD subband resources, you need to configure SBFD symbols. For example, the first type of subband is a frequency domain resource configured on an SBFD symbol, and the second type of subband is a frequency domain resource configured on an SBFD symbol.

[0162] The TDD frame structure is divided into UL slots, DL slots, and S slots based on time slots. Symbols in S slots can be configured as UL symbols, DL symbols, and flexible (F) symbols. F symbols can be used for UL, DL, or GP. Regarding the TDD frame structure, the base station can inform the UE through the semi-static configuration mode TDD-UL-DL-ConfigCommon / TDD-UL-DL-ConfigDedicated.

[0163] In TDD-UL-DL-ConfigCommon, a maximum of two frame structure modes can be configured. Each mode can configure the period of the frame structure, as well as the specific configuration of each time slot and symbol in the period (such as DL, UL or F, etc.). These two modes together determine the current overall frame structure.

[0164] A frame structure configured semi-statically in TDD is shown in FIG3 . The uplink and downlink ratio is 1:4, the S time slot is time slot 3, and symbols #10 and #11 are configured as F symbols for GP for uplink and downlink switching.

[0165] In TDD-UL-DL-ConfigDedicated, the symbols configured as F in TDD-UL-DL-ConfigCommon can be changed, and the F symbols can be further configured as DL or UL.

[0166] In addition, the TDD frame structure can also be dynamically indicated through DCI, allowing the time slot format indication (SFI: Slot Format Indicator) to be sent through DCI format 2_0 to change the F symbol and further configure it into a DL or UL symbol, but it is not allowed to change the semi-statically configured DL and UL symbols.

[0167] In the above-mentioned method, the semi-static configuration scheme of the frame structure does not clearly indicate the location of the SBFD symbols, so it is impossible to configure the SBFD symbols. On the other hand, the DL and UL symbols cannot be changed through dynamic DCI indication, which is not conducive to the flexible adjustment of the SBFD symbol location.

[0168] In response to the above findings, this embodiment proposes a method for configuring SBFD symbols, including a semi-static configuration method for SBFD symbols and a dynamic configuration method for SBFD symbols, which are described below.

[0169] Case 1: Semi-static configuration method of SBFD symbols.

[0170] The base station may send a frame structure configuration message to the UE, and the UE receives the frame structure configuration message. The frame structure configuration message may be a semi-static frame structure configuration message, and the frame structure configuration message includes the start symbol of the SBFD symbol and the length of the SBFD symbol. The UE may determine all SBFD symbols used to configure SBFD subband resources (such as uplink subband resources and downlink subband resources) based on the start symbol of the SBFD symbol and the length of the SBFD symbol.

[0171] For example, SBFD symbols (time domain resources) can be indicated by a semi-static frame structure configuration message, which can be an RRC message such as TDD-UL-DL-ConfigCommon (common configuration) or TDD-UL-DL-ConfigDedicated (dedicated configuration). For example, the SBFD frame structure is DXXXU, where X represents the time slot containing the SBFD symbol, which contains one or more SBFD symbols.

[0172] In one example, the SBFD symbol can be semi-statically configured using the start symbol of the SBFD symbol and the length of the SBFD symbol. The start symbol of the SBFD symbol indicates the first symbol of the SBFD symbol in the frame structure pattern (e.g., the symbol index value starting from the first symbol), and the length of the SBFD symbol indicates the number of symbols continuing from the start symbol. Alternatively, the start symbol of the SBFD symbol indicates the last symbol of the SBFD symbol in the frame structure pattern (e.g., the symbol index value starting from the last symbol), and the length of the SBFD symbol indicates the number of symbols continuing from the start symbol.

[0173] For flexibility, two SBFD-related patterns can be configured within a frame structure period. These two SBFD patterns are optional, enabled only 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 including a start symbol and length. Both sets of SBFD configuration information are optional.

[0174] The value of the start symbol of the first set of configuration information indicates the first symbol of the SBFD, which is calculated backward from the first symbol in the current frame structure pattern, and the length indicates the symbol length of the SBFD.

[0175] The value of the start symbol of the second set of configuration information indicates the first symbol of the SBFD, which is calculated from the last symbol in the current frame structure pattern. The length indicates the symbol length of the SBFD.

[0176] If the length of each SBFD group, measured from its starting symbol, exceeds the range of the frame structure pattern period, the excess part is invalid. There is no restriction on whether two groups of SBFD symbols overlap or not, which is actually configured by the base station.

[0177] In an example, the RRC message for SBFD symbol configuration is as follows:

[0178] Case 2: Dynamic configuration method of SBFD symbols.

[0179] The base station may send an RRC message to the UE, which receives the RRC message. The RRC message may include multiple time slot format combinations, each of which includes a time slot format type indicating an SBFD symbol. The base station may send a DCI message to the UE, which receives the DCI message. The DCI message may include an index of a target time slot format combination. After receiving the DCI message, the UE may select a corresponding target time slot format combination from the multiple time slot format combinations based on the index of the target time slot format combination; based on the target time slot format combination, the UE may determine all SBFD symbols used to configure SBFD subband resources (such as uplink subband resources and downlink subband resources).

[0180] For example, SBFD symbols can be dynamically configured using a slot format indication method. To better support SBFD, a new slot format type, designated as the X symbol, is introduced when SBFD is enabled, based on the existing D, U, and F symbols in the slot structure. This new slot format type represents an SBFD symbol. In other words, SBFD mode supports four symbol types: D, U, F, and X. This allows the slot format indication method to indicate the slot format type of an SBFD symbol.

[0181] For example, the TDD frame structure is implemented through semi-static configuration and dynamic indication. Multiple slot format combinations (SFCs) are defined in high-layer signaling using the SFI. For example, the base station selects slot formats that meet service requirements and adds them to the SFC. Table 7 shows some of the slot formats. D represents a DL symbol, U represents an UL symbol, and F represents a flexible symbol. Each SFC is identified by a fixed ID and contains one or more slot format types. After completing the SFI configuration, the base station sends the multiple slot format combinations to the UE in an RRC message.

[0182] Table 7

[0183] Then, after configuring multiple slot format combinations through RRC messages, the base station notifies the UE of the index of the SFC to be used through the periodic PDCCH (Physical Downlink Control Channel) in DCI format 2_0. Part of the information structure of DCI format 2_0 is as follows:

[0184] -If the higher layer parameter slotFormatCombToAddModList is configured,

[0185] -Slot format indicator 1,Slot format indicator 2,…,Slot format indicator N

[0186] When configuring the timeslot structure using the SFI method, only the F symbol in the timeslot structure can be changed.

[0187] In the SBFD system, multiple SBFD SFCs are also semi-statically configured, with the SFI in the DCI indicating which specific SBFD SFC to use. However, in the dynamic configuration of SBFD symbols, any symbol can be modified using the SFI, changing D / U / F to X, or changing F / X to D or U. To distinguish it from the slot formats in Table 7, a new slot format is introduced specifically for SBFD. In slot format indexes #0-#55, all slot formats (#2-#55) containing the F symbol are changed to X. New slot format types are then defined starting with #56, as shown in Table 8.

[0188] Table 8

[0189] Once the position of the SBFD symbol in the time slot is determined, it is only necessary to select the appropriate time slot format index in Table 8. When the time slot format index is added to the SFC of the SBFD, the X symbol represents the SBFD symbol. For example, an example of the RRC message of the SFC can be as follows:

[0190] SlotFormatCombinationsPerCell::=SEQUENCE{

[0191] …

[0192] slotFormatCombinations SEQUENCE(SIZE(1..maxNrofSlotFormatCombinationsPerSet))OF SlotFormatCombination OPTIONAL,

[0193] slotFormatCombinations-SBFD SEQUENCE(SIZE(1..maxNrofSlotFormatCombinationsPerSet))OF SlotFormatCombination-SBFD OPTIONAL,

[0194] ...,

[0195] }

[0196] The SlotFormatCombination-SBFD field represents the SBFD slot format combination field. This field can carry the combination identifier corresponding to the SBFD slot format combination and the slot format index of the slot format. The SlotFormatCombination-SBFD field is configured with a maximum of maxNrofSlotFormatCombinationsPerSet elements. Each element is defined as follows:

[0197] SlotFormatCombination-SBFD::=SEQUENCE{

[0198] slotFormatCombinationId-SBFD SlotFormatCombinationId,

[0199] slotFormats-SBFD SEQUENCE(SIZE(1..maxNrofSlotFormatsPerCombination))OF INTEGER(0..255)

[0200] }

[0201] Among them, slotFormatCombinationId-SBFD represents the identifier, and its value starts from 0 and goes up to maxNrofSlotFormatCombinationsPerSet-1 in sequence, that is, the value can be 0, 1, 2, ..., maxNrofSlotFormatCombinationsPerSet-1, etc. slotFormats-SBFDx represents the unique slot format index of the slot format. A maximum of maxNrofSlotFormatsPerCombination can be configured. The slot format index value is selected from Table 8, and each index value can range from 0 to 255. If error! Reference source not found. After slotFormatCombinationId-SBFD is configured, slotFormatCombinations will be ignored, that is, the slot structure configuration in SBFD mode will overwrite the slot structure configuration in non-SBFD mode. On the contrary, if slotFormatCombinations-SBFD is not configured, then the frame structure depends on the configuration of slotFormatCombinations, that is, it works according to the mode in traditional TDD.

[0202] When indicating the SFI for SBFD via DCI, DCI format 2_0 continues to be used, but a new SFI is introduced for SBFD. The configuration in DCI format 2_0 can be seen as follows: SBFD Slot format indicator 1, SBFD Slot format indicator 2, ..., SBFD Slot format indicator N correspond to slotFormatCombinationId-SBFD in SlotFormatCombination-SBFD, respectively.

[0203] -If the higher layer parameter slotFormatCombToAddModList is configured,

[0204] -if the higher layer parameter slotFormatCombinations-SBFD is configured

[0205] -SBFD Slot format indicator 1,SBFD Slot format indicator 2,…,SBFD Slot format indicator N,

[0206] -else

[0207] -Slot format indicator 1,Slot format indicator 2,…,Slot format indicator N

[0208] When the D / U / F configuration is set to X, the activated and effective subband resource configuration is used. That is, the uplink subband resource, downlink subband resource, and guard subband resource configuration in the newly configured X symbol are the same as the subband resource configuration in other X symbols. When changing from X to D or U, the X symbol becomes an all-D or all-U symbol.

[0209] As can be seen from the above technical solution, the UE determines the starting or ending position of the protection subband based on the subband resource indication message. The length of the protection subband is determined based on the protection subband configuration message. The UE then determines the protection subband resources from the BWP and can distinguish between uplink subband resources, downlink subband resources, and protection subband resources within the BWP. The UE uses SBFD subband resources for data transmission, improving resource utilization, increasing network coverage and capacity, and reducing downlink transmission latency.

[0210] By configuring a fixed guard bandwidth, SBFD frequency domain resource configuration only requires uplink or downlink subband resources, reducing air interface signaling overhead. By proposing different subband frequency domain resource configuration schemes, flexible subband frequency domain resource configuration is possible, with different schemes resulting in different air interface signaling overheads, allowing for flexible selection. SBFD symbols can be flexibly configured, such as by changing D / U / F symbols to X symbols, or X / F symbols to D / U symbols, to adapt to different scenario requirements.

[0211] To better support SBFD communication systems and maintain compatibility with TDD systems, sub-band frequency domain resources are configured for SBFD communications. SBFD sub-band frequency domain resources are configured by configuring DL sub-bands or UL sub-bands and guard bandwidth sizes. Different sub-band configuration strategies are proposed to achieve SBFD sub-band frequency domain resource configuration, reducing air interface signaling overhead and freeing up air interface resources for data transmission. Based on the configured sub-band frequency domain resources, the BWP can be dynamically configured, allowing for flexible adjustment to serve different service scenarios.

[0212] Based on the same inventive concept, a subband resource determination device corresponding to the subband resource determination method, as well as a base station and a UE are also provided. Since the principles of solving the problem by the base station and the UE are similar to those of the subband resource determination method, the implementation of the base station and the UE refers to the subband resource determination method, and the repeated parts are not repeated here.

[0213] Based on the same application concept as the above method, this application proposes an example of a subband resource determination device applied to a user equipment, as shown in FIG4A , comprising:

[0214] A receiving module 41 is configured to receive a subband resource indication message sent by a base station, where the subband resource indication message includes frequency domain resource information of a first type of subband;

[0215] a determination module 42, configured to determine a starting position and / or an ending position of the first-class subband based on the frequency domain resources of the first-class subband indicated by the frequency domain resource information of the first-class subband, and determine a starting position or an ending position of the guard subband using the starting position and / or the ending position of the first-class subband;

[0216] The receiving module 41 is further configured to receive a protection subband configuration message sent by the base station, where the protection subband configuration message includes the length of the protection subband;

[0217] The determination module 42 is further configured to determine the guard subband resources from the BWP using the starting position of the guard subband and the length of the guard subband, or to determine the guard subband resources from the BWP based on the ending position of the guard subband and the length of the guard subband.

[0218] In one example, when the receiving module 41 receives the configuration message of the protection subband sent by the base station, it is specifically used to: receive a semi-static configuration message sent by the base station, where the semi-static configuration message includes the length of the protection subband; or

[0219] Receive a semi-static configuration message sent by a base station, where the semi-static configuration message includes a subband length list, where the subband length list includes lengths of multiple guard subbands; and receive a dynamic configuration message sent by the base station, where the dynamic configuration message includes index information, where the index information is used to indicate a guard subband length corresponding to the index information, selected from the subband length list.

[0220] In one example, the determining module 42 determines the starting position or ending position of the guard subband based on the starting position and / or ending position of the first-type subband: if the first-type subband is located at the upper boundary of the BWP, determining the ending position of the guard subband based on the starting position of the first-type subband; or

[0221] If the first-type sub-band is located at the lower boundary of the BWP, the starting position of the protection sub-band is determined by the ending position of the first-type sub-band; or

[0222] If the first-class sub-band is located in the middle of the BWP, the starting position of the guard sub-band above the first-class sub-band is determined by the ending position of the first-class sub-band, and the ending position of the guard sub-band below the first-class sub-band is determined by the starting position of the first-class sub-band.

[0223] In one example, the frequency domain resource information of the first type of subband includes a bitmap configuration of a subband resource group occupied by the first type of subband; wherein, if the bitmap configuration indicates that the subband resource group corresponds to a first value, then the subband resource group is occupied by the first type of subband; if the bitmap configuration indicates that the subband resource group corresponds to a second value, then the subband resource group is not occupied by the first type of subband; or,

[0224] The frequency domain resource information of the first type of subband includes a first subband resource indicator value corresponding to the first type of subband; wherein the first subband resource indicator value is determined by the starting physical resource block position of the first type of subband and the number of consecutive physical resource blocks occupied by the first type of subband; or

[0225] The frequency domain resource information of the first type of subband includes a second subband resource indication value corresponding to the first type of subband; wherein the second subband resource indication value is determined by the starting subband resource group position of the first type of subband and the number of consecutive subband resource groups occupied by the first type of subband.

[0226] In one example, the process of obtaining the first subband resource indicator value includes:

[0227]

[0228] Among them, L PRB Indicates the number of consecutive physical resource blocks occupied by the first type of subband, Indicates the total number of physical resource blocks in the BWP where the first type of subband is located, SBRIV indicates the first subband resource indicator value, PRB Start Indicates the starting physical resource block position of the first type of subband.

[0229] In one example, the process of obtaining the second subband resource indicator value includes:

[0230] like The second subband resource indicator value is determined in the following manner: SBRIV=N SBG *(L SBG -1)+SBG start Otherwise, the second subband resource indicator value is determined as follows: SBRIV = N SBG *(N SBG -L SBG +1)+(NSBG -1-SBG start );

[0231] Among them, L SBG Indicates the number of consecutive subband resource groups occupied by the first type of subband, N SBG Indicates the total number of subband resource groups in the BWP where the first type of subband is located, SBRIV indicates the second subband resource indicator value, SBG start Indicates the starting subband resource group position of the first type of subband.

[0232] In one example, the receiving module 41 is further configured to receive a subband configuration type indication message sent by the base station; if the subband configuration type indication message is used to indicate a bitmap type, determining that the subband resource indication message carries a bitmap configuration of a subband resource group occupied by the first type of subband; or

[0233] If the subband configuration type indication message is used to indicate the SBRIV type, determining that the subband resource indication message carries the first subband resource indication value corresponding to the first type of subband; or

[0234] If the subband configuration type indication message is used to indicate SBRIV and SBG types, it is determined that the subband resource indication message carries the second subband resource indication value corresponding to the first type of subband.

[0235] In one example, the first type of subband is an uplink subband, or the first type of subband is a downlink subband; the determination module 42 is further used to: if the frequency domain resources of the first type of subband are uplink subband resources, then based on the uplink subband resources and the protection subband resources, determine the downlink subband resources from the BWP; or, if the frequency domain resources of the first type of subband are downlink subband resources, then based on the downlink subband resources and the protection subband resources, determine the uplink subband resources from the BWP.

[0236] In one example, the BWP includes multiple subband resource groups; the apparatus further includes:

[0237] a sending module, configured to, if the sub-band resource group is a frequency domain resource group including uplink sub-band resources and protection sub-band resources, send uplink data in the uplink sub-band resources of the sub-band resource group, or prohibit sending uplink data in the uplink sub-band resources of the sub-band resource group;

[0238] The sending module is further configured to, if the sub-band resource group includes downlink sub-band resources and protection sub-band resources, receive downlink data on the downlink sub-band resources of the sub-band resource group, or prohibit receiving downlink data on the downlink sub-band resources of the sub-band resource group.

[0239] In one example, the first type of subband is a frequency domain resource configured on a SBFD symbol;

[0240] The receiving module 41 is further configured to: receive a frame structure configuration message sent by the base station, the frame structure configuration message including a start symbol of an SBFD symbol and a length of the SBFD symbol; wherein the frame structure configuration message is a semi-static frame structure configuration message;

[0241] The determining module 42 is further configured to determine all SBFD symbols used to configure the first type of subband according to the starting symbol of the SBFD symbol and the length of the SBFD symbol.

[0242] In an example, the start symbol of the SBFD symbol indicates the first symbol of the SBFD symbol in the frame structure, and the length of the SBFD symbol indicates the number of symbols continuing from the start symbol; or, the start symbol of the SBFD symbol indicates the last symbol of the SBFD symbol in the frame structure, and the length of the SBFD symbol indicates the number of symbols continuing from the start symbol.

[0243] If the frame structure configuration message is a semi-static frame structure configuration message, the frame structure configuration message is TDD-UL-DL-ConfigCommon or TDD-UL-DL-ConfigDedicated in the RRC message.

[0244] In one example, the first type of subband is a frequency domain resource configured on a SBFD symbol;

[0245] The receiving module 41 is further used to receive an RRC message sent by the base station, the RRC message including multiple time slot format combinations, each time slot format combination including a time slot format type for indicating an SBFD symbol; receive a DCI message sent by the base station, the DCI message including an index of a target time slot format combination; the determining module 42 is further used to select a corresponding target time slot format combination from the multiple time slot format combinations according to the index of the target time slot format combination; and determine all SBFD symbols used to configure the first type of subband based on the target time slot format combination.

[0246] Based on the same application concept as the above method, this application proposes an example of a subband resource determination device, which is applied to a base station. As shown in FIG4B , the device may include:

[0247] An acquisition module 43 is configured to acquire frequency domain resource information of a first type of sub-band;

[0248] a sending module 44, configured to send a subband resource indication message to a user equipment, the subband resource indication message including frequency domain resource information of a first-category subband; wherein the subband resource indication message is used to instruct the user equipment to determine a starting position and / or an ending position of the first-category subband based on the frequency domain resources of the first-category subband indicated by the frequency domain resource information of the first-category subband, and to determine a starting position or an ending position of a guard subband based on the starting position and / or the ending position of the first-category subband;

[0249] The acquisition module 43 is further configured to acquire the length of the protection subband;

[0250] The sending module 44 is further configured to send a protection subband configuration message to the user equipment, where the protection subband configuration message includes the length of the protection subband; wherein the configuration message is used to instruct the user equipment to determine the protection subband resources from the BWP using the starting position of the protection subband and the length of the protection subband, or to determine the protection subband resources from the BWP based on the ending position of the protection subband and the length of the protection subband.

[0251] In one example, when the sending module 44 sends a configuration message of a protection subband to the user equipment, it is specifically used to: send a semi-static configuration message to the user equipment, where the semi-static configuration message includes the length of the protection subband; or send a semi-static configuration message to the user equipment, where the semi-static configuration message includes a subband length list, where the subband length list includes the lengths of multiple protection subbands; and send a dynamic configuration message to the user equipment, where the dynamic configuration message includes index information, where the index information is used to indicate a length of a protection subband corresponding to the index information selected from the subband length list.

[0253] The frequency domain resource information of the first type of subband includes a first subband resource indicator value corresponding to the first type of subband; wherein the first subband resource indicator value is determined by the starting physical resource block position of the first type of subband and the number of consecutive physical resource blocks occupied by the first type of subband; or

[0254] The frequency domain resource information of the first type of subband includes a second subband resource indication value corresponding to the first type of subband; wherein the second subband resource indication value is determined by the starting subband resource group position of the first type of subband and the number of consecutive subband resource groups occupied by the first type of subband.

[0255] In one example, the process of obtaining the first subband resource indicator value includes:

[0256]

[0257] Among them, L PRB Indicates the number of consecutive physical resource blocks occupied by the first type of subband, Indicates the total number of physical resource blocks in the BWP where the first type of subband is located, SBRIV indicates the first subband resource indicator value, PRB Start Indicates the starting physical resource block position of the first type of subband.

[0258] In one example, the process of obtaining the second subband resource indicator value includes:

[0259] like The second subband resource indicator value is determined in the following manner: SBRIV=N SBG *(L SBG -1)+SBG start Otherwise, the second subband resource indicator value is determined as follows: SBRIV = N SBG *(N SBG -L SBG +1)+(N SBG -1-SBG start );

[0260] Among them, L SBG Indicates the number of consecutive subband resource groups occupied by the first type of subband, N SBG Indicates the total number of subband resource groups in the BWP where the first type of subband is located, SBRIV indicates the second subband resource indicator value, SBG start Indicates the starting subband resource group position of the first type of subband.

[0261] In one example, the sending module 44 is further configured to send a subband configuration type indication message to the user equipment; wherein: if the subband configuration type indication message is used to indicate a bitmap type, the subband resource indication message carries a bitmap configuration of a subband resource group occupied by the first type of subband; or, if the subband configuration type indication message is used to indicate an SBRIV type, the subband resource indication message carries a first subband resource indication value corresponding to the first type of subband; or,

[0262] If the subband configuration type indication message is used to indicate SBRIV and SBG types, the subband resource indication message carries the second subband resource indication value corresponding to the first type of subband.

[0263] In one example, the first type of subband is a frequency domain resource configured on a SBFD symbol;

[0264] The sending module 44 is further configured to send a frame structure configuration message to the user equipment, where the frame structure configuration message includes a start symbol of an SBFD symbol and a length of the SBFD symbol; wherein the frame structure configuration message is a semi-static frame structure configuration message;

[0265] The starting symbol of the SBFD symbol and the length of the SBFD symbol are used to determine all SBFD symbols configured for the first type of subband;

[0270] Based on the same application concept as the above method, a base station is proposed in an example of the present application, as shown in Figure 5A. The base station may include a processor 511 and a machine-readable storage medium 512, and the machine-readable storage medium 512 stores machine-executable instructions that can be executed by the processor 511; the processor 511 is used to execute the machine-executable instructions to implement the subband resource determination method disclosed in the above example of the present application.
