In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0051] The embodiments of the present disclosure provide a method, device, and storage medium for determining resources.

[0052] In a first aspect, an embodiment of the present disclosure provides a method for determining resources, including:

[0055] In the above embodiment, the terminal can determine the frequency domain resources occupied by the physical shared channel in different types of time slots based on the single FDRA field in the first information, thereby avoiding increasing the signaling overhead of the first information and improving the reliability of full-duplex communication.

[0195] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0196] As shown in FIG1 , a communication system 100 includes a terminal 101 and a network device 102 .

[0199] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0200] In some embodiments, the access network device 102-1 can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0201] In some embodiments, network device 102 includes a core network device 102-2. Core network device 102-2 can be a single device, multiple devices, or a group of devices. Network elements can be virtual or physical. The core network, for example, includes at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0202] Terminal 101 can access core network device 102-2 through access network device 102-1.

[0203] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0204] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0205] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, systems utilizing other communication methods, and next-generation systems based on these. Furthermore, a combination of multiple systems (for example, a combination of LTE or LTE-A with 5G) may also be used.

[0206] Uplink resources can be allocated within the active uplink bandwidth part (active UL BWP). When the uplink subband (UL subband) is located in the middle of the UL BWP, the network device can ensure that the uplink transmission is located in the middle of the active UL BWP to ensure that the uplink transmission can be within the UL subband.

[0207] Currently, a network device can configure an uplink subband (UL subband) for uplink data transmission in a downlink time slot (DL slot) for a full-duplex terminal 101, and schedule the terminal's uplink data transmission within the time-frequency range of the UL subband. Generally speaking, the size and frequency domain position of the UL subband configured by the network device 102 are different from the size and frequency domain range of the activated uplink bandwidth part (UL Bandwidth Part, active UL BWP). For example, as shown in FIG1B , the frequency domain range of the UL subband can completely fall within the frequency domain range of the UL BWP. For another example, as shown in FIG1C , the frequency domain range of the UL subband does not completely fall within the frequency domain range of the UL BWP.

[0208] The 3rd Generation Partnership Project (3GPP) has reached a conclusion regarding the transmission behavior of full-duplex terminals on the UL subband: the terminal does not expect to receive uplink data outside the frequency domain range of the UL BWP.

[0209] In the embodiment of the present disclosure, the physical shared channel performs repeated transmission on multiple time slots and may occupy time slots of different types.

[0210] Exemplarily, the physical shared channel may include but is not limited to a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) and a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH).

[0211] Exemplarily, in the embodiments of the present disclosure, a first type of time slot and a second type of time slot may be included.

[0212] A first sub-band is configured on the first type of time slot, and a transmission direction of the first type of time slot is different from a transmission direction of the first sub-band.

[0213] For example, the first type of time slot may be called a Subband-Based Full Duplex (SBFD) time slot. This type of time slot is configured with a first subband, and the transmission direction of the SBFD time slot is different from the transmission direction of the first subband.

[0214] For example, the transmission direction of the time slot is uplink, and the transmission direction of the first sub-band is downlink.

[0215] For another example, the transmission direction of the time slot is downlink, and the transmission direction of the first subband is uplink.

[0216] For another example, the transmission direction of the time slot is flexible, and the transmission direction of the first sub-band is uplink or downlink.

[0217] The first subband is not configured in the second type of time slot.

[0218] Exemplarily, the second type of time slot may be referred to as a non-subband-based full duplex (non-SBFD) time slot.

[0219] The transmission mode of the second type of time slot can be uplink, downlink or flexible, and no first subband with the opposite transmission direction is configured.

[0220] In the embodiment of the present disclosure, when the physical shared channel is repeatedly transmitted in the SBFD time slot and the non-SBFD time slot, the frequency domain resource allocation can be determined in the following manner:

[0221] Option 1: Frequency Domain Resource Allocation (FDRA) is determined separately for SBFD time slots and non-SBFD time slots.

[0222] Option 1-1: Independent FDRA configuration or indication for SBFD timeslots and non-SBFD timeslots.

[0223] Option 1-2, separate frequency resources are determined for SBFD timeslots and non-SBFD timeslots based on a single FDRA configuration or indication.

[0224] Option 1-3: single FDRA configuration or indication and resource block (RB) offset.

[0225] Option 2: rate matching or puncturing is performed on RBs outside the DL sub-band or UL sub-band of the DL / UL channel or signal.

[0226] Option 3: discard or delay the DL channels, DL signals, UL channels, and UL signals that overlap with RBs outside the DL subband or UL subband in the SBFD time slot.

[0227] For options 1-2 (option 1-3 is essentially the same as option 1-2), there is no need to add additional signaling overhead, and there will be no loss of transmission performance, which can effectively give play to the technical advantages of SBFD technology in reducing latency and increasing uplink coverage. Therefore, the present disclosure provides a method and device for determining resources, and a storage medium based on options 1-2, which can allow the terminal to determine the frequency domain resources occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot respectively through a single FDRA domain. Ensure that the terminal and the network device have a consistent understanding of the frequency domain resources occupied by the physical shared channel in different types of time slots, avoid increasing the signaling overhead of the first information, and improve the reliability of full-duplex communication.

[0228] FIG2A is an interactive diagram of a method for determining resources according to an embodiment of the present disclosure. As shown in FIG2A , an embodiment of the present disclosure relates to a method for determining resources, and the method includes:

[0229] Step S2101 : In response to a physical shared channel needing to perform repeated transmission on multiple time slots of multiple types, the network device 102 respectively determines resources occupied by the physical shared channel for transmission on a first type of time slot and a second type of time slot.

[0230] In some embodiments, physical shared channels include but are not limited to PDSCH and PUSCH.

[0231] In some embodiments, the terms "uplink", "uplink", "physical uplink", etc. can be used interchangeably.

[0232] In some embodiments, the terms "downlink," "physical downlink," and "downlink" are interchangeable. In some embodiments, the plurality of time slots of the plurality of types include time slots of a first type and time slots of a second type.

[0233] In some embodiments, a first sub-band is configured on a first type of time slot, and a transmission direction of the first type of time slot is different from a transmission direction of the first sub-band. The first type of time slot may be the SBFD time slot in the aforementioned embodiment.

[0234] In one example, the transmission direction refers to uplink, downlink, or flexible.

[0235] Exemplarily, the transmission direction of the first type of time slot may be uplink, and the transmission direction of the first sub-band may be downlink.

[0236] Exemplarily, the transmission direction of the first type of time slot may be downlink, and the transmission direction of the first subband may be uplink.

[0237] Exemplarily, the transmission direction of the first type of time slot may be flexible, and the transmission direction of the first subband may be downlink.

[0238] Exemplarily, the transmission direction of the first type of time slot may be flexible, and the transmission direction of the first subband may be uplink.

[0239] In some embodiments, the first subband is not configured in the second type of timeslot.The second type of timeslot may be the non-SBFD timeslot in the aforementioned embodiment.

[0240] In some embodiments, resources include but are not limited to frequency domain resources and / or time domain resources. Resources may also include spatial domain resources, which is not limited in this disclosure.

[0241] In some embodiments, the network device 102 may determine the time domain resources occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot, respectively. The determined frequency domain resources may be configured for the terminal 101 to transmit the physical shared channel.

[0242] In an example, the network device 102 may determine the symbol occupied by the physical shared channel in the first type of time slot and the second type of time slot, respectively. Exemplarily, the symbol may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol.

[0243] In some embodiments, the network device 102 may determine frequency domain resources occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot, respectively. The determined frequency domain resources may be configured for the terminal 101 to transmit the physical shared channel.

[0244] In an example, the network device 102 may configure the frequency domain resources occupied by the physical shared channel within a frequency domain range of a first sub-band on a first type of time slot.

[0245] In an example, the network device 102 may configure the frequency domain resources occupied by the physical shared channel within the frequency domain range of the BWP in an activated state on the second type of time slot.

[0246] In some embodiments, the network device 102 determines the resources (including time domain resources and frequency domain resources) occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot, respectively, which may include at least one of the following:

[0247] Determining that the number of second resources occupied by each repeated transmission of the physical shared channel is equal to the number of first resources;

[0248] Determining a starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot;

[0249] Determine a starting symbol index occupied by each repeated transmission of the physical shared channel in the second time slot.

[0250] In an example, the second resource quantity may be determined based on the number of RBs and the number of symbols occupied by each repeated transmission of the physical shared channel.

[0251] Exemplarily, the second resource quantity may be equal to the product of the number of RBs occupied by each repeated transmission of the physical shared channel in the second time slot and the number of symbols.

[0252] Exemplarily, the second resource quantity may be obtained by mapping based on a mapping relationship among the number of RBs, the number of symbols, and the number of resources.

[0253] In the embodiment of the present disclosure, there is no limitation on the method for determining the quantity of the second resources.

[0254] In an example, the first resource quantity is the resource quantity occupied by the first physical shared channel in the first time slot. Exemplarily, the first resource quantity may be determined based on the number of RBs and the number of symbols occupied by the first physical shared channel in the first time slot.

[0255] Exemplarily, the first resource quantity may be equal to the product of the number of RBs occupied by the first physical shared channel in the first time slot and the number of symbols.

[0256] Exemplarily, the first resource quantity may be obtained by mapping based on a mapping relationship among the number of RBs, the number of symbols, and the number of resources.

[0257] In the embodiment of the present disclosure, there is no limitation on the method for determining the first resource quantity.

[0258] The first time slot is a time slot for transmitting the first physical shared channel configured by the network device 102. The first time slot may be an SBFD time slot or a non-SBFD time slot, which is not limited in the present disclosure.

[0259] For example, if the first time slot is a non-SBFD time slot, the number of RBs occupied by the first physical shared channel in the first time slot is 20, and the number of symbols occupied is 7, then the first resource quantity N = 20 × 7 = 140. The second resource quantity occupied by each repeated transmission of the physical shared channel subsequently configured by the network device 102 is also 140.

[0260] In one example, the network device 102 may determine the starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot based on a first method, for example, the first method may be a protocol agreed method or a predefined method. The second time slot is the time slot occupied by any repeated transmission (repetetion) of the physical shared channel, and the second time slot may be an SBFD time slot or a non-SBFD time slot, which is not limited in the present disclosure. Of course, the first time slot and at least one second time slot include both SBFD time slots and non-SBFD time slots. Accordingly, when the network device 102 determines the starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot based on the first method, the network device 102 does not need to indicate the starting RB index through downlink signaling or downlink message, and the terminal 101 can also determine the starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot based on the first method.

[0261] For example, the first method includes but is not limited to any of the following:

[0262] Determine a starting RB index based on the terminal identifier;

[0263] Determine the starting RB index based on the Cell-Radio Network Temporary Identifier (C-RNTI);

[0264] The starting RB index is determined based on the specific RB index.

[0265] The network device 102 may perform a modulo operation on the terminal identifier using the total number of available resources and configure the quotient or remainder as the starting RB index. Alternatively, the network device 102 may determine the starting RB index based on a mapping relationship between the terminal identifier and the starting RB index.

[0266] The network device 102 may perform a modulo operation on the C-RNTI using the total number of available resources and configure the quotient or remainder as the starting RB index. Alternatively, the network device 102 may determine the starting RB index based on a mapping relationship between the C-RNTI and the starting RB index.

[0267] The network device 102 may configure a specific RB index within the first sub-band, such as a maximum value, a minimum value, or other specific value of the RB index, as the starting RB index.

[0268] The above description is merely exemplary, and any scheme in which the network device 102 configures the starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot based on a predefined manner should fall within the protection scope of the present disclosure.

[0269] In one example, the network device 102 may configure, according to its own decision, the starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot. Accordingly, the network device 102 may indicate the configured starting RB index through downlink signaling or a downlink message, and the terminal 101 may also determine the starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot based on the configuration of the network device 102.

[0270] In one example, the network device 102 can determine the starting symbol index occupied by each repeated transmission of the physical shared channel on the second time slot based on a first method, such as a protocol-agreed method. The second time slot is the time slot occupied by any repeated transmission (repetetion) of the physical shared channel, and the second time slot can be an SBFD time slot or a non-SBFD time slot, which is not limited in the present disclosure. Accordingly, when the network device 102 determines the starting symbol index occupied by each repeated transmission of the physical shared channel on the second time slot based on the first method, the network device 102 does not need to indicate the starting RB index through downlink signaling or downlink message, and the terminal 101 can also determine the starting symbol index occupied by each repeated transmission of the physical shared channel on the second time slot based on the first method.

[0271] Of course, in the embodiment of the present disclosure, the first time slot and the second time slot include both SBFD time slots and non-SBFD time slots.

[0272] For example, the first method includes but is not limited to any of the following:

[0273] Determine the starting symbol index based on the terminal identifier;

[0274] Determine the starting symbol index based on the C-RNTI;

[0275] Determines the starting symbol index based on a specific symbol index.

[0276] The network device 102 may perform a modulo operation on the terminal identifier using the total number of available resources and configure the quotient or remainder as the starting symbol index. Alternatively, the network device 102 may determine the starting symbol index according to a mapping relationship between the terminal identifier and the starting symbol index.

[0277] The network device 102 may perform a modulo operation on the C-RNTI using the total number of available resources and configure the quotient or remainder as the starting symbol index. Alternatively, the network device 102 may determine the starting symbol index based on a mapping relationship between the C-RNTI and the starting symbol index.

[0278] Therein, one time slot includes 14 OFDM symbols, and the network device 102 may determine a specific symbol index, such as 0, 1, ..., 13, as a starting RB index.

[0279] The above description is merely exemplary, and any scheme in which the network device 102 configures the starting symbol index occupied by each repeated transmission of the physical shared channel in the second time slot based on a predefined manner should fall within the protection scope of the present disclosure.

[0280] In one example, the network device 102 may configure, according to its own decision, the starting symbol index occupied by each repeated transmission of the physical shared channel in the second time slot. Accordingly, the network device 102 may indicate the configured starting symbol index through downlink signaling or a downlink message, and the terminal 101 may also determine the starting symbol index occupied by each repeated transmission of the physical shared channel in the second time slot based on the configuration of the network device 102.

[0281] It should also be noted that the symbol occupied by each repeated transmission of the physical shared channel configured by the network device may belong to the same second time slot, and the second time slot may be an SBFD time slot or a non-SBFD time slot.

[0282] Alternatively, the symbol occupied by each repeated transmission of the physical shared channel configured by the network device may belong to multiple consecutive second time slots, and the multiple consecutive second time slots may all be SBFD time slots or all be non-SBFD time slots, or may include SBFD time slots and non-SBFD time slots. If the first time slot is a non-SBFD time slot, the multiple consecutive second time slots may all be SBFD time slots. If the first time slot is an SBFD time slot, the multiple consecutive second time slots may all be non-SBFD time slots. If the first time slot is an SBFD time slot or a non-SBFD time slot, the multiple consecutive second time slots may include SBFD time slots and non-SBFD time slots.

[0283] In some embodiments, the total number of resources occupied by the physical shared channel configured by the network device 102 for the terminal 101 may be less than or equal to the number of third resources included in the first subband on any time slot of the first type, that is, not exceeding the resource upper limit of the first subband.

[0284] The total number of resources may be determined based on the number of RBs and symbols occupied by the physical shared channel.

[0285] Exemplarily, the total number of resources may be equal to the product of the number of RBs occupied by the physical shared channel and the number of symbols.

[0286] Exemplarily, the total number of resources may be obtained by mapping based on a mapping relationship among the number of RBs, the number of symbols, and the number of resources.

[0287] In the embodiments of the present disclosure, there is no limitation on the method for determining the total number of resources.

[0288] The third resource quantity is determined based on the number of RBs and the number of symbols occupied by the first subband in the first type of time slot.

[0289] Exemplarily, the third resource quantity may be equal to the product of the number of RBs and the number of symbols occupied by the first subband in the first type of time slot. For example, if the first subband in any SBFD time slot includes 24 RBs and 20 symbols, then the third resource quantity is 24 × 20 = 480. The total number of resources occupied by the physical shared channel configured by network device 102 for the terminal should be less than or equal to 480, that is, the product of the number of RBs and the number of symbols occupied by the physical shared channel is less than or equal to 480. This ensures that the RB and symbol resources occupied by the physical shared channel in SBFD time slots or non-SBFD time slots do not exceed the resource upper limit of the first subband.

[0290] Exemplarily, the third resource quantity may be obtained by mapping based on a mapping relationship among the number of RBs, the number of symbols, and the number of resources.

[0291] In the embodiment of the present disclosure, there is no limitation on the method for determining the quantity of the third resource.

[0292] At this time, the symbol occupied by each repeated transmission of the physical shared channel configured by the network device 102 belongs to a second time slot, wherein the second time slot can be an SBFD time slot or a non-SBFD time slot.

[0293] In some embodiments, when the total number of RBs and symbols occupied by the physical shared channel configured by network device 102 for terminal 101 does not exceed the resource upper limit of the first subband, the coding information for repeated transmission of the physical shared channel remains unchanged. The coding information includes, but is not limited to, the MCS level and / or the size of the Transfer Block Set (TBS).

[0294] In some embodiments, the total number of resources occupied by the physical shared channel configured by the network device 102 may also exceed the resource upper limit of the first subband. In this case, to ensure that the number of second resources occupied by each repeated transmission of the physical shared channel is equal to the number of first resources, the symbol occupied by each repeated transmission of the physical shared channel configured by the network device 102 may belong to multiple consecutive second time slots. The multiple consecutive second time slots may all be SBFD time slots, or all be non-SBFD time slots, or may include both SBFD time slots and non-SBFD time slots, which is not limited in this disclosure.

[0295] In some embodiments, terms such as "frame", "radio frame", "subframe", "slot", "sub-slot", "mini-slot", "symbol", "symbol", and "transmission time interval (TTI)" can be used interchangeably.

[0296] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0297] Step S2102: The network device 102 determines a bit value of a frequency domain resource allocation FDRA field based on the frequency domain resources respectively occupied by the physical shared channel in the first type of time slot and the second type of time slot.

[0298] In some embodiments, the network device 102 may determine a bit value of the FDRA field based on a resource block (RB) occupied by the first physical shared channel in the first time slot.

[0299] In one example, when the FDRA field adopts resource allocation type 0 (RA type 0), the network device 102 can determine the bitmap indicated by the FDRA field based on the RB or resource block group (RBG) occupied by the first physical shared channel in the first time slot.

[0300] For example, assuming that there are 8 RBs in the first time slot, the first physical shared channel occupies RB#2 to RB#7 in the first time slot, and the bit map indicated by the bit value of the FDRA field is: 00111100.

[0301] Exemplarily, in order to save signaling resources in the FDRA domain, the bitmap indicated by the bit value of the FDRA domain may be determined according to the RBG occupied by the first physical shared channel in the first time slot.

[0302] For example, an RBG includes two consecutive RBs. Assuming that there are 8 RBs in the first time slot, the first physical shared channel occupies RB#2 to RB#7 in the first time slot, and the bit map indicated by the bit value of the FDRA field is: 0110.

[0303] In one example, when the FDRA field uses Resource Allocation Type 1 (RA type 1), the bit value of the FDRA field is used to indicate the Start and Length Indicator Value (SLIV). The network device 102 can determine the bit value of the FDRA field based on the starting RB index and the number of continuous RBs of the first physical shared channel in the first time slot.

[0304] For example, there are 8 RBs in the first time slot, and the first physical shared channel occupies RB#2 to RB#7 in the first time slot, the starting RB index is 2, and the number of continuous RBs is 6. Based on the correspondence between the starting RB index, the number of continuous RBs and SLIV, the terminal can determine a unique SLIV, assuming it is n. The network device 102 determines that the bit value indicated by the FDRA field is used to indicate the value n.

[0305] In some embodiments, when the network device 102 configures the starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot based on its own decision, the FDRA field is also used to indicate the starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot.

[0306] In some embodiments, the network device 102 may also determine a bit value of the frequency domain resource indication information based on the resource block (RB) occupied by the first physical shared channel in the first time slot. The frequency domain resource indication information may be used to indicate the frequency domain resource for performing repeated transmission on the physical shared channel configured by the network device 102 for the terminal 101.

[0307] The method for determining the bit value of the frequency domain resource indication information is similar to the method for determining the bit value of the FDRA field, and will not be repeated here.

[0308] Step S2103: The network device 102 determines a bit value of the TDRA field in the first information based on the time domain resources respectively occupied by the physical shared channel in the first type of time slot and the second type of time slot.

[0309] In some embodiments, the network device 102 may determine a bit value of the TDRA field based on the symbol occupied by the first physical shared channel in the first time slot.

[0310] The method for determining the bit value of the TDRA field is similar to the method for determining the bit value of the TDRA field in step S2102. For example, the bitmap indicated by the bit value of the TDRA field can be determined based on the symbol occupied by the first physical shared channel in the first time slot. Alternatively, a SLIV can be determined based on the starting symbol index and the number of consecutive symbols of the first physical shared channel in the first time slot, and the bit value of the TDRA field is determined to indicate the specific value of the SLIV.

[0311] In some embodiments, when the network device 102 configures the starting symbol index occupied by each repeated transmission of the physical shared channel in the second time slot based on its own decision, the TDRA field is also used to indicate the starting symbol index occupied by each repeated transmission of the physical shared channel in the second time slot.

[0312] In some embodiments, the network device 102 may also determine a bit value of the time domain resource indication information based on the symbol occupied by the first physical shared channel in the first time slot. The time domain resource indication information may be used to indicate the time domain resources for performing repeated transmission on the physical shared channel configured by the network device 102 for the terminal 101.

[0313] The method for determining the bit value of the time domain resource indication information is similar to the method for determining the bit value of the TDRA field, and will not be repeated here.

[0314] Step S2104: Send first information to the terminal 101; wherein the first information carries a single FDRA field.

[0315] In some embodiments, terminal 101 receives the first information.

[0316] In some embodiments, the first information may be DCI or Radio Resource Control (RRC) signaling.

[0317] In some embodiments, the first information carries a single FDRA field, and the bit value of the FDRA field has been determined in the aforementioned step S2102.

[0318] In some embodiments, the first information carries frequency domain resource indication information. The bit value of the frequency domain resource indication information has been determined in the aforementioned step S2102. In this case, the network device 102 only needs to indicate the frequency domain resource of the first physical shared channel through the frequency domain resource indication information, and does not need to indicate the frequency domain resource of each repeated transmission of the physical shared channel, thereby also achieving the purpose of saving signaling resources for the first information.

[0319] In some embodiments, the first information may also carry frequency domain resource indication information, where the frequency domain resource indication information is used to indicate the frequency domain resources occupied by the physical shared channel in the first type of time slot and the second type of time slot, respectively.

[0320] In some embodiments, the first information carries a single TDRA field, and the bit value of the TDRA field has been determined in the aforementioned step S2103.

[0321] In some embodiments, the first information carries time domain resource indication information. The bit value of the time domain resource indication information has been determined in the aforementioned step S2103. In this case, the network device 102 only needs to indicate the time domain resource of the first physical shared channel through the time domain resource indication information, and does not need to indicate the time domain resource of each repeated transmission of the physical shared channel, thereby also achieving the purpose of saving signaling resources for the first information.

[0322] In some embodiments, the first information may also carry multiple TDRA fields. Exemplarily, the number of TDRA fields is 2, which are used to indicate the time domain resources occupied by the physical shared channel in the first type of time slot and the second type of time slot, respectively.

[0323] In some embodiments, the first information may also carry time domain resource indication information, where the time domain resource indication information is used to indicate the time domain resources occupied by the physical shared channel in the first type of time slot and the second type of time slot, respectively.

[0324] In some embodiments, the name of the first information is not limited, and it can be, for example, an indication message, a first message, a first signaling, a DCI, an RRC message, an RRC signaling, etc.

[0325] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0326] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0327] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0328] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0329] In step S2105 , the terminal 101 determines frequency domain resources occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot, respectively, based on the indication of the FDRA field.

[0330] In some embodiments, the terminal 101 may determine the RB occupied by the first physical shared channel in the first time slot based on an indication of the FDRA field.

[0331] In an example, the terminal 101 may determine the RB occupied by the first physical shared channel in the first time slot based on the bitmap indicated by the FDRA field.

[0332] In an example, the terminal 101 may determine the RB occupied by the first physical shared channel in the first time slot based on the value indicated by the bit value of the FDRA field, that is, SLIV.

[0333] Furthermore, the terminal 101 may determine the symbol occupied by the first physical shared channel in the first time slot based on an indication of the TDRA field in the first information.

[0334] In an example, the terminal 101 may determine the symbol occupied by the first physical shared channel in the first time slot based on the bitmap indicated by the TDRA field.

[0335] In an example, the terminal 101 may determine the symbol occupied by the first physical shared channel in the first time slot based on the value indicated by the bit value of the TDRA field, that is, SLIV.

[0336] The terminal 101 may determine the first resource quantity occupied by the first physical shared channel in the first time slot based on the number of RBs and the number of symbols occupied by the first physical shared channel in the first time slot.

[0337] Exemplarily, the terminal 101 may determine that the first resource quantity is equal to the product of the number of RBs occupied by the first physical shared channel in the first time slot and the number of symbols.

[0338] Exemplarily, the terminal 101 may determine the first resource quantity as the resource quantity obtained by mapping the number of RBs and the number of symbols occupied by the first physical shared channel in the first time slot based on the mapping relationship among the number of RBs, the number of symbols, and the number of resources.

[0339] The first time slot may be an SBFD time slot or a non-SBFD time slot, which is not limited in the present disclosure.

[0340] For example, the number of RBs occupied by the first physical shared channel in the first time slot is 20, the number of symbols occupied is 7, and the first resource quantity N=20×7=140.

[0341] The terminal 101 may determine the RBs and symbols occupied by each repeated transmission of the physical shared channel in the second time slot based on the first resource quantity.

[0342] In some embodiments, the terminal 101 may determine that the second resource quantity occupied by each repeated transmission of the physical shared channel is equal to the first resource quantity, wherein the second resource quantity is determined based on the number of RBs and the number of symbols occupied by each repeated transmission of the physical shared channel.

[0343] And / or, the terminal 101 may determine the starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot.

[0344] And / or, the terminal 101 may also determine a starting symbol index occupied by each repeated transmission of the physical shared channel in the second time slot.

[0345] In an example, assuming that the number of first resources is 140, the terminal 101 may determine that the number of second resources occupied by each repeated transmission of the physical shared channel is also 140.

[0346] Exemplarily, the terminal 101 may determine the RBs and symbols occupied by each repeated transmission of the physical shared channel in the second time slot based on the second resource quantity.

[0347] The second time slot is an SBFD time slot, the RB occupied by each repeated transmission of the physical shared channel is located in the frequency domain range of the first subband, and the product of the number of RBs occupied by each repeated transmission of the physical shared channel and the number of symbols in the second time slot is determined to be equal to the second resource quantity.

[0348] The second time slot is a non-SBFD time slot, the RB occupied by each repeated transmission of the physical shared channel is within the frequency domain range of the BWP, and the product of the number of RBs occupied by each repeated transmission of the physical shared channel and the number of symbols determined in the second time slot is equal to the second resource quantity.

[0349] Exemplarily, the terminal 101 may determine the number of RBs and the number of symbols obtained by mapping the second number of resources as the RBs and symbols occupied by each repeated transmission of the physical shared channel based on the mapping relationship among the number of RBs, the number of symbols, and the number of resources.

[0350] In an example, the terminal 101 may determine the starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot based on the first method.

[0351] The first method includes but is not limited to: determining the starting RB index based on the terminal identifier, the C-RNTI, and the specific RB index included in the first subband. The method in which the terminal 101 determines the starting RB index based on the first method is similar to the method in which the network device 102 determines the starting RB index based on the first method, and will not be repeated here.

[0352] In an example, the terminal 101 may re-parse the FDRA field to determine the starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot.

[0353] For example, the FDRA field indicates a bit map, and the terminal 101 determines the starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot by re-parsing the FDRA field in the second time slot.

[0354] For another example, the bit value of the FDRA field indicates SLIV, and the terminal 101 determines the starting RB index occupied by each repeated transmission of the physical shared channel in the second time slot by re-parsing the FDRA field in the second time slot.

[0355] In an example, the terminal 101 may determine the starting symbol index occupied by each repeated transmission of the physical shared channel in the second time slot based on the first method.

[0356] The first method includes but is not limited to: determining the starting symbol index based on the terminal identifier, C-RNTI, and specific symbol index. The method in which the terminal 101 determines the starting symbol index based on the first method is similar to the method in which the network device 102 determines the starting symbol index based on the first method, and will not be repeated here.

[0357] In an example, the terminal 101 may re-parse the TDRA field to determine the starting symbol index occupied by each repeated transmission of the physical shared channel in the second time slot.

[0358] For example, the TDRA field indicates a bit map, and the terminal 101 determines the starting symbol index occupied by each repeated transmission of the physical shared channel in the second time slot by re-parsing the TDRA field in the second time slot.

[0359] For another example, the bit value of the TDRA field indicates SLIV, and the terminal 101 determines the starting symbol index occupied by each repeated transmission of the physical shared channel in the second time slot by re-parsing the TDRA field in the second time slot.

[0360] In some embodiments, the terminal 101 does not expect the total number of resources occupied by the physical shared channel to be greater than the third number of resources included in the first subband on any time slot of the first type, that is, not to exceed the resource upper limit of the first subband.

[0361] The total number of resources is determined based on the number of RBs and symbols occupied by the physical shared channel.

[0362] Exemplarily, the total number of resources may be equal to the product of the number of RBs occupied by the physical shared channel and the number of symbols.

[0363] Exemplarily, the total number of resources may be obtained by mapping based on a mapping relationship among the number of RBs, the number of symbols, and the number of resources.

[0364] In the embodiments of the present disclosure, there is no limitation on the method for determining the total number of resources.

[0365] The third resource quantity is determined based on the number of RBs and the number of symbols occupied by the first subband in the first type of time slot.

[0366] Exemplarily, the third resource quantity may be equal to the product of the number of RBs occupied by the first subband in the first type of time slot and the number of symbols.

[0367] Exemplarily, the third resource quantity may be obtained by mapping based on a mapping relationship among the number of RBs, the number of symbols, and the number of resources.

[0368] In the embodiment of the present disclosure, there is no limitation on the method for determining the quantity of the third resource.

[0369] In some embodiments, the terminal 101 does not expect the total number of resources occupied by the received physical shared channels to be greater than the third number of resources included in the first sub-band on any of the first type of time slots. Alternatively, the terminal 101 does not expect the total number of resources occupied by the sent physical shared channels by the network device 102 to be greater than the third number of resources included in the first sub-band on any of the first type of time slots.

[0370] Among them, "not expecting to receive" can be interpreted as not receiving on time domain resources and / or frequency domain resources, or it can be interpreted as not performing subsequent processing on the data after receiving it; "not expecting to send" can be interpreted as not sending, or it can be interpreted as sending but not expecting the recipient to respond to the content sent.

[0371] Accordingly, the terminal 101 determines that the symbol occupied by each repeated transmission of the physical shared channel belongs to a second time slot, wherein the second time slot may be an SBFD time slot or a non-SBFD time slot, which is not limited in the present disclosure.

[0372] In some embodiments, when terminal 101 determines that the first resource quantity exceeds the resource upper limit of the first subband, it may determine that the symbol occupied by each repeated transmission of the physical shared channel belongs to multiple consecutive second time slots. The multiple consecutive second time slots may all be SBFD time slots, or all be non-SBFD time slots, or may include both SBFD time slots and non-SBFD time slots, which is not limited in this disclosure.

[0373] In some embodiments, the terminal 101 may determine that a physical shared channel performs repeated transmission over the multiple time slots, and the coding information of the physical shared channel remains unchanged; wherein the coding information is used to indicate at least one of the following: MCS level; TBS size.

[0374] In some embodiments, the method for determining resources involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2105. For example, step S2101 can be implemented as an independent embodiment, step S2102 can be implemented as an independent embodiment, step S2103 can be implemented as an independent embodiment, steps S2102+S2103 can be implemented as an independent embodiment, steps S2101 to S2103 can be implemented as independent embodiments, step S2104 can be implemented as an independent embodiment, step S2105 can be implemented as an independent embodiment, steps S2104+S2105 can be implemented as independent embodiments, and steps S2101 to S2105 can be implemented as independent embodiments, but are not limited thereto.

[0375] In some embodiments, step S2102 and step S2103 may be executed in an interchanged order or simultaneously.

[0376] In some embodiments, step S2101 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if repeated transmission of the physical shared channel is not performed, that is, the network device 102 determines not to perform coverage enhancement, step S2101 may not be performed.

[0377] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the terminal 101 determines, based on the first method or other method, the frequency domain resources occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot, step S2102 may not be performed.

[0378] In some embodiments, step S2103 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the terminal 101 determines the time domain resources occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot, respectively, based on the first method or other methods, step S2103 may not be performed.

[0379] In some embodiments, step S2104 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the terminal 101 receives resource indication information sent by another execution entity, thereby determining the frequency domain resources and / or time domain resources occupied by the physical shared channel when transmitting in the first type of time slot and the second type of time slot, respectively, step S2104 may not be performed.

[0380] In some embodiments, step S2105 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the terminal 101 determines the frequency domain resources occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot based on other indication information, step S2105 may not be performed.

[0381] In some embodiments, steps S2101 to S2105 are optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, the terminal 101 and the network device 102 use the method shown in the subsequent FIG. 2B to determine the frequency domain resources occupied by the physical shared channel for performing repeated transmission in multiple time slots of multiple types, and steps S2101 to S2105 may not be performed.

[0382] In the above embodiment, the terminal can determine the frequency domain resources occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot, respectively, based on the indication of the single FDRA field in the first information sent by the network device. This ensures that the terminal and the network device have a consistent understanding of the frequency domain resources occupied by the physical shared channel in different types of time slots, thereby improving the reliability of full-duplex communication.

[0383] FIG2B is an interactive diagram of a method for determining resources according to an embodiment of the present disclosure. As shown in FIG2B , an embodiment of the present disclosure relates to a method for determining resources, and the method includes:

[0384] Step S2201 : In response to a physical shared channel needing to perform repeated transmission on multiple time slots of multiple types, the network device 102 respectively determines resources occupied by the physical shared channel for transmission on a first type of time slot and a second type of time slot.

[0385] The implementation method of step S2201 is similar to the implementation method of the above-mentioned step S2101, and will not be repeated here.

[0386] Step S2202 : The network device 102 determines a bit value of a frequency domain resource allocation FDRA field based on the frequency domain resources respectively occupied by the physical shared channel in the first type of time slot and the second type of time slot.

[0387] In some embodiments, when the FDRA field adopts RA type 0, the network device 102 may determine the bitmap indicated by the FDRA field based on the RBGs occupied by the physical shared channel in the first type of time slot and the second type of time slot.

[0388] In some embodiments, when the FDRA field adopts RA type 0, the network device 102 may determine the bit value of the FDRA field based on the starting RB index and the number of RBs respectively occupied by the physical shared channel in the first type of time slot and the second type of time slot.

[0389] Exemplarily, the bit value of the FDRA field is used to indicate SLIV, and the SLIV is determined based on the starting RB index and the number of RBs occupied by the physical shared channel for transmission in the first type of time slot or the second type of time slot.

[0390] In some embodiments, the network device 102 may also determine a bit value of the frequency domain resource indication information based on the RBGs occupied by the physical shared channel in the first time slot and the second type of time slot, respectively. The frequency domain resource indication information may be used to indicate the frequency domain resources for performing repeated transmission on the physical shared channel configured by the network device 102 for the terminal 101.

[0391] In some embodiments, the network device 102 may also determine the bit value of the frequency domain resource indication information based on the starting RB index and the number of RBs occupied by the physical shared channel in the first time slot and the second type of time slot, respectively. The frequency domain resource indication information may be used to indicate the frequency domain resources for performing repeated transmission on the physical shared channel configured by the network device 102 for the terminal 101.

[0392] The method for determining the bit value of the frequency domain resource indication information is similar to the method for determining the bit value of the FDRA field, and will not be repeated here.

[0393] Step S2203: Send first information to the terminal 101; wherein the first information carries a single FDRA field.

[0394] In some embodiments, terminal 101 receives the first information.

[0395] In some embodiments, the first information may be DCI or Radio Resource Control (RRC) signaling.

[0396] In some embodiments, the first information carries a single FDRA field, and the bit value of the FDRA field has been determined in the aforementioned step S2202.

[0397] In some embodiments, the first information carries frequency domain resource indication information, and the bit value of the frequency domain resource indication information has been determined in the aforementioned step S2202.

[0398] In some embodiments, the name of the first information is not limited, and it can be, for example, an indication message, a first message, a first signaling, a DCI, an RRC message, an RRC signaling, etc.

[0399] In the embodiment of the present disclosure, whether the first information includes a TDRA field, the number of TDRA fields included, and the bit value of the TDRA field may not be considered.

[0400] It is understandable that the number of TDRA fields may be 2. Accordingly, the network device 102 may determine the bit values ​​of the two TDRA fields based on the symbols occupied by the physical shared channel in the first type of time slot and the second type of time slot, respectively.

[0401] Alternatively, the number of TDRA fields is 1, and the network device 102 determines the bit value of the TDRA field in a manner similar to that of a single FDRA field.

[0402] In the embodiment of the present disclosure, it is not necessary to pay attention to whether the first information contains time domain resource indication information or the bit value of the time domain resource indication information.

[0403] It is understandable that, in the embodiment of the present disclosure, the bit value of the TDRA field in the first information may be determined in combination with the relevant steps in FIG. 2A , for example, step S2103 .

[0404] In step S2204, the terminal 101 determines, based on the indication of the FDRA field, the frequency domain resources occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot.

[0405] In some embodiments, the FDRA field adopts RA type 0, and the terminal 101 determines the resource block groups RBGs occupied by the physical shared channel in the first type of time slot and the second type of time slot based on the bit map indicated by the FDRA field.

[0406] In some embodiments, the FDRA field adopts RA type 1, and the terminal 101 determines the starting RB index and the number of RBs occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot respectively based on the SLIV indicated by the FDRA field.

[0407] Step S2205 , the network device 102 sends second information to the terminal 101 .

[0408] In some embodiments, if the number of RB resources occupied by the physical shared channel configured by the network device 102 exceeds the RB upper limit of the first sub-band, the network device 102 may determine that the terminal 101 adjusts the coding information of the physical shared channel in the first type of time slot. When the physical shared channel uses the adjusted coding information, each RB occupied in the first type of time slot is located within the frequency domain of the first sub-band.

[0409] The network device 102 may send second information to the terminal 101. The second information is used to indicate the adjusted coding information, wherein the coding information includes but is not limited to the MCS level and the TBS size.

[0410] In some embodiments, terminal 101 receives second information.

[0411] In some embodiments, the name of the second information is not limited.

[0412] In some embodiments, the network device 102 may send the second information via DCI or RRC signaling.

[0413] In some embodiments, the network device 102 may send the second information to the terminal 101 via the first information.

[0414] For example, the network device 101 sends the adjusted coding information to the terminal 101 via DCI. The DCI carries a single FDRA field, which is used by the terminal 101 to determine the frequency domain resources occupied by repeated transmission of the physical shared channel in different types of time slots.

[0415] Alternatively, the network device 102 may not send the second information, and the terminal 101 may determine the adjusted coding information according to the first method. The coding information includes but is not limited to the MCS level and the TBS size.

[0416] Step S2206: At least part of the RBs occupied by the physical shared channel in the first type of time slot is outside the frequency domain range of the first subband, and the terminal 101 adjusts the coding information of the physical shared channel in the first type of time slot.

[0417] In some embodiments, the terminal 101 may determine the adjusted coding information based on the first method.

[0418] Exemplarily, the first method may be a protocol-agreed method or a predefined method.

[0419] Exemplarily, the terminal 101 may determine the adjusted coding information according to a mapping relationship between the number of RBs occupied by the physical shared channel in the first type of time slot and the coding information.

[0420] Exemplarily, the terminal 101 may determine specific coding information as the adjusted coding information.

[0421] The specific coding information may be coding information agreed upon in the protocol.

[0422] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0423] In some embodiments, the terminal 101 may receive the second information sent by the network device 102 to determine the adjusted coding information.

[0424] Each RB occupied by the physical shared channel using the adjusted coding information in the first type of time slot is located in the frequency domain range of the first subband.

[0425] In some embodiments, the method for determining resources involved in the embodiments of the present disclosure may include at least one of steps S2201 to S2206. For example, step S2201 can be implemented as an independent embodiment, step S2202 can be implemented as an independent embodiment, step S2203 can be implemented as an independent embodiment, steps S2102+S2203 can be implemented as independent embodiments, steps S2201 to S2204 can be implemented as independent embodiments, step S2205 can be implemented as an independent embodiment, step S2206 can be implemented as an independent embodiment, steps S2205+S2206 can be implemented as independent embodiments, and steps S2201 to S2206 can be implemented as independent embodiments, but are not limited thereto.

[0426] In some embodiments, steps S2201 to S2206 involved in the embodiments of the present disclosure can be combined with steps S2101 to S2105 in Figure 2A. For example, in the case of multiple network devices, some network devices and terminal 101 can use steps S2101 to S2105 in Figure 2A to determine the frequency domain resources occupied by the physical shared channel in different types of time slots, and some network devices and terminal 101 can use steps S2201 to S2206 in Figure 2B to determine the frequency domain resources occupied by the physical shared channel in different types of time slots. For another example, network device 102 can use steps S2101 to S2105 in Figure 2A or steps S2201 to S2206 in Figure 2B to determine the frequency domain resources occupied by the physical shared channel in different types of time slots with terminal 101 during different time periods. For another example, network device 102 may perform one or more of steps S2101 to S2105 in FIG. 2A before or simultaneously with any of steps 2201 to S2206. This disclosure is not limited to this. In some embodiments, step S2201 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if repeated transmission of the physical shared channel is not performed, that is, if network device 102 determines not to perform coverage enhancement, step S2201 may not be performed.

[0427] In some embodiments, step S2202 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the terminal 101 determines, based on the first method or other method, the frequency domain resources occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot, step S2202 may not be performed.

[0428] In some embodiments, step S2203 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the terminal 101 receives resource indication information sent by another execution entity, thereby determining the frequency domain resources and / or time domain resources occupied by the physical shared channel when transmitting in the first type of time slot and the second type of time slot, step S2203 may not be performed.

[0429] In some embodiments, step S2204 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the terminal 101 determines the frequency domain resources occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot based on other resource indication information, step S2204 may not be performed.

[0430] In some embodiments, step S2205 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the terminal 101 determines the adjusted coding information based on the first method, step S2204 may not be performed.

[0431] In some embodiments, step S2206 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when all RBs occupied by the physical shared channel in the first type of time slot are within the frequency domain of the first subband, step S2206 may not be performed.

[0432] In some embodiments, steps S2201 to S2206 are optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, the terminal 101 and the network device 102 use the method shown in FIG2A to determine the frequency domain resources occupied by the physical shared channel for performing repeated transmission in multiple time slots of multiple types, and steps S2201 to S2206 may not be performed.

[0433] In the above embodiment, the terminal can determine the frequency domain resources occupied by the physical shared channel for transmission in the first type of time slot and the second type of time slot, respectively, based on the indication of the single FDRA field in the first information sent by the network device, and can adjust the coding information of the physical shared channel so that the RB occupied by the physical shared channel in the first type of time slot is within the frequency domain range of the first subband. This ensures that the terminal and the network device have a consistent understanding of the frequency domain resources occupied by the physical shared channel in different types of time slots, thereby improving the reliability of full-duplex communication.

[0544] On the terminal side, for an SBFD-aware terminal, when it needs to send / receive data channels on multiple slots, and the slots where the data channels are transmitted include SBFD slots and non-SBFD slots, the frequency domain resources of the channels in the SBFD slots and non-SBFD slots are determined by the following method:

[0545] Method 1: The terminal determines the first number of RB-symbol resources N required for PDSCH or PUSCH transmission based on the time-frequency resource occupancy of the first PDSCH or PUSCH in the corresponding slot. Taking N as a reference, the time-frequency resources occupied by each repeated transmission of the PUSCH or PDSCH in the second time slot are determined. The terminal does not expect the total time-frequency resources allocated by the base station to exceed the resource upper limit in any slot, that is, the terminal does not expect the RB-symbol resources occupied by the PUSCH / PDSCH in the UL slot or DL ​​slot to exceed the total resources of the UL subband / DL subband.

[0546] For example, if the first PDSCH or PUSCH is transmitted in a non-SBFD slot and occupies 20 RBs in the frequency domain and 7 OFDM symbols in the time domain, then N = 20 × 7. Therefore, the time-frequency resources occupied in the SBFD slot should also be N, for example, N = 10 × 14, which means it occupies 10 RBs in the frequency domain and 14 OFDM symbols in the time domain.

[0547] The starting RB index (index) of the frequency domain resource is determined in a predefined manner, or by re-analyzing the FDRA.

[0548] The starting OFDM symbol index of the time domain resource is determined in a predefined manner or by re-parsing the TDRA.

[0549] Method 2: The terminal determines the first resource number N of RB-symbols required for the transmission of the PDSCH or PUSCH based on the time-frequency resource occupancy of the first PDSCH or PUSCH in the corresponding slot. Taking N as a reference, determine the time-frequency resources occupied by each repeated transmission of PUSCH or PDSCH in the second time slot. When the total amount of time-frequency resources occupied by PDSCH or PUSCH is greater than the carrying capacity of one SBFD slot, the terminal determines the total amount of time-frequency resources occupied by its PDSCH or PUSCH in M ​​consecutive SBFD slots, that is, one TBS is transmitted in the DL subband or UL subband of M consecutive SBFD slots. M is a positive integer greater than 1.

[0550] For example, if the first PDSCH or PUSCH is transmitted in a non-SBFD slot and occupies 20 RBs in the frequency domain and 7 OFDM symbols in the time domain, then N = 20 × 14. The time-frequency resources occupied in the SBFD slot should also be N, for example, N = 10 × 14, which means it occupies 10 RBs in the frequency domain and 28 OFDM symbols in the time domain.

[0551] The starting RB index of the frequency domain resource is determined in a predefined manner, or by re-analyzing the FDRA.

[0552] The starting OFDM index of the time domain resource is determined in a predefined manner or by re-analyzing the TDRA.

[0553] Method 3: The terminal determines the frequency domain resource allocation for the SBFD slot and the non-SBFD slot respectively according to the FDRA indication field. When the frequency domain resource range allocated by the base station exceeds the subband range, the terminal adjusts the expected MCS level and / or TBS size for the slot.

[0554] For RA type 0, the terminal determines the RBG for data channel transmission according to the bitmap

[0555] For RA type 1, the terminal independently parses SLIV within the active BWP and subband range to determine S and L.

[0556] Network device side:

[0557] When a network device schedules or configures an uplink transmission that spans both an SBFD slot and a non-SBFD slot, the network device uses the FDRA field carried in the DCI to determine the frequency domain resources for the SBFD slot and the non-SBFD slot, respectively, using the following method:

[0558] Method 1: The network device determines the first resource quantity N of RB-symbols required for the transmission of the PDSCH or PUSCH based on the time-frequency resource allocation of the first PDSCH or PUSCH in the corresponding slot. With N as a reference, the time-frequency resources occupied by each repeated transmission of the PUSCH or PDSCH in the second time slot are determined. The terminal does not expect the total time-frequency resources allocated by the network device to exceed the resource upper limit in any one slot, that is, the terminal does not expect the RB-symbol resources occupied by the PUSCH or PDSCH in the UL slot or DL ​​slot to exceed the total resources of the UL subband or DL ​​subband.

[0559] The specific method is as on the terminal side and will not be repeated here.

[0560] Method 2: The network device determines the first resource number N of RB-symbols required for the transmission of the PDSCH or PUSCH based on the time-frequency resource allocation of the first PDSCH or PUSCH in the corresponding slot. Taking N as a reference, determine the time-frequency resources occupied by each repeated transmission of PUSCH or PDSCH in the second time slot. When the total amount of time-frequency resources occupied by PDSCH or PUSCH is greater than the carrying capacity of one SBFD slot, the terminal determines the total amount of time-frequency resources occupied by its PDSCH or PUSCH in M ​​consecutive SBFD slots, that is, one TBS is transmitted in the DL subband or UL subband of M consecutive SBFD slots. M is a positive integer greater than 1.

[0561] The specific method is as on the terminal side and will not be repeated here.

[0562] Method 3: The network device determines the frequency domain resource allocation for the SBFD slot and the non-SBFD slot respectively according to the FDRA indication information. When the frequency domain resource range allocated by the base station exceeds the subband range, the terminal adjusts the MCS level and / or TBS size expected in the slot.

[0563] The specific method is as on the terminal side and will not be repeated here.

[0564] In Example 1, it is assumed that the terminal is a Rel-18 or later version terminal with half-duplex capability or full-duplex capability, and this patent does not impose any restrictions. It is assumed that the base station side performs full-duplex operation in the downlink time slot of the time division duplexing (TDD) frequency band, that is, it schedules downlink data and uplink data at the same time. When performing full-duplex operation, the base station side adopts one of the following methods, and this patent does not impose any restrictions:

[0565] The frequency domain resources used for DL ​​transmission and UL transmission within a DL slot are independent of each other and do not overlap, as shown in FIG4A ;

[0566] The frequency domain resources used for DL ​​transmission and UL transmission in the DL slot completely overlap, as shown in FIG4B ;

[0567] Frequency domain resources used for DL ​​transmission and UL transmission in a DL slot partially overlap, as shown in FIG4C .

[0568] Assume that the current system's time-division duplex uplink and downlink (TDD) configuration is DDDDDDSUUU, where D stands for downlink, U stands for uplink, and F stands for flexible. Furthermore, the bandwidth of the DL BWP in the DL slot differs from the bandwidth of the UL BWP in the UL slot. For the TDD band, the center frequencies of the DL BWP and UL BWP must be aligned. For example, as shown in Figure 4D, the center frequencies of the DL BWP and UL BWP configurations are aligned.

[0569] In this embodiment, it is assumed that the base station schedules uplink transmission of an SBFD-aware UE using DCI format 0-0, DCI format 0-1, DCI format 0-2, DCI format 0-3, or any other DCI format for scheduling uplink transmission. Alternatively, the base station configures a periodic PUSCH for the terminal through RRC signaling. This patent does not impose any restrictions on the uplink transmission type and indication method. The uplink transmission can be within the UL subband of the SBFD slot or within the active UL BWP of the non-SBFD slot. This patent does not impose any restrictions.

[0570] In this embodiment, the PUSCH is used as an example, and it is assumed that repeated transmission is enabled for the PUSCH, and the number of repeated transmissions R = 4. A specific example is as follows. As can be seen, because the frequency domain resources occupied by the UL subband are often smaller than the frequency domain resources occupied by the active UL BWP, the available uplink frequency domain resources in the SBFD slot are smaller than those in the non-SBFD slot.

[0571] In case 1, as shown in Figure 5A, assume that the first PUSCH transmission occurs in slot #4. The frequency resources occupied by PUSCH are not considered in the UL subband size. Therefore, PUSCH repetitions #2, #3, and #4 all exceed the frequency range of the UL subband. Case 1 prevents the PUSCH in the SBFD slot from being properly transmitted, impacting transmission performance.

[0572] Case 2, shown in Figure 5B, assumes the first PUSCH transmission is in slot #4, and the PUSCH frequency resources are considered within the UL subband size, ensuring that the PUSCH frequency resources are within the UL subband. Case 2 limits PUSCH scheduling flexibility and can cause uplink resource segmentation within the UL slot.

[0573] In this embodiment, the frequency domain resources occupied by the repeatedly transmitted or periodically transmitted PUSCH in the SBFD slot and the non-SBFD slot are determined by the following method, thereby saving FDRA indication information, improving the flexibility of PUSCH scheduling, configuration and transmission, and improving the system uplink performance.

[0574] For example, as shown in Figure 6A, the terminal determines the first number of RB-symbol resources N required for PDSCH / PUSCH transmission based on the time-frequency resource occupancy of the first PUSCH in the corresponding slot. Using N as a reference, the time-frequency resources occupied by PUSCH / PDSCH transmitted in other slots are determined. The terminal does not expect the total time-frequency resources allocated by the base station to exceed the resource upper limit in any slot, that is, the terminal does not expect the RB-symbol resources occupied by PUSCH / PDSCH in the UL slot or DL ​​slot to exceed the total resources of the UL subband / DL subband.

[0575] In this embodiment, it is assumed that the first PUSCH transmission of PUSCH occurs in a non-SBFD slot, that is, in a UL slot or a flexible slot. Specifically, take the aforementioned TDD UL-DL time slot structure and UL subband configuration as an example. Assume that the number of repeated PUSCH transmissions is R=4, and the first PUSCH is transmitted in slot#4. In this embodiment, it is assumed that the PUSCH is scheduled through DCI. The DCI has only one FDRA and TDRA domain for one PUSCH on a cell. Assume that the UL subband occupies 20 RBs in the frequency domain and occupies the entire slot in the time domain.

[0576] In this embodiment, it is assumed that the time-frequency resources occupied by the first PUSCH indicated by the base station are: 40 RBs in the frequency domain and 7 OFDM symbols in the time domain. It can be seen that the frequency domain resources occupied by the PUSCH exceed the frequency domain resources included in the UL subband.

[0577] Based on the above resource allocation, the terminal and base station determine time-frequency resources consisting of 40*7 RBs within the UL subband. In this embodiment, the PUSCH occupies 14 OFDM symbols in the time domain and 20 RBs in the frequency domain within the SBFD slot. This ensures that the total number of time-frequency resources occupied by SBFD and non-SBFD slots is the same, allowing them to fully reuse the same MCS level and TBS.

[0578] Furthermore, in order to determine the starting position of the time-frequency resources occupied by the PUSCH in the SBFD slot, the following method can be used to determine it:

[0579] For the starting resource position in the frequency domain (ie, the starting RB index),

[0580] It is determined in a manner predefined in the protocol, for example, the frequency domain starting position of the UE in the UL subband is determined according to the UE ID or C-RNTI, or the RB with the largest index or the RB with the smallest index contained in the UL subband.

[0581] Alternatively, the FDRA field is reparsed (type1RA), that is, the SLIV indicated by the FDRA field is parsed to obtain S, and S is modulo the number of RBs included in the UL subband to finally obtain its starting frequency domain position within the UL subband range.

[0582] Alternatively, the starting frequency domain position in the SBFD slot configured by RRC signaling is determined:

[0583] For the time domain starting position, that is, the starting OFDM symbol index;

[0584] It is determined in a manner predefined in the protocol, for example, the time domain starting position of the UE in the SBFD slot is determined according to the UE ID or C-RNTI, or is OFDM symbol #0.

[0585] Alternatively, the starting OFDM symbol is still determined according to TDRA

[0586] Alternatively, the starting OFDM symbol is determined according to the TDRA and the number of symbols it occupies in the SBFD slot.

[0587] The size of the frequency domain resources and the size of the time domain resources are converted using the aforementioned method.

[0588] Of course, this patent does not impose any restrictions on any TDD configuration and any UL subband.

[0589] Furthermore, the terminal does not expect the total number of time-frequency resources after conversion to exceed the total number of time-frequency resources included in one slot of the UL subband.

[0590] In Example 2, the prerequisites are the same as those in Example 1. Case 1 is shown in FIG5A , and Case 2 is shown in FIG5B .

[0591] In this embodiment, the frequency domain resources occupied by the repeatedly transmitted or periodically transmitted PUSCH in the SBFD slot and the non-SBFD slot are determined by the following method, thereby saving FDRA indication information, improving the flexibility of PUSCH scheduling, configuration and transmission, and improving the system uplink performance.

[0592] For example, as shown in Figure 6B, the terminal determines the number of RB-symbol resources N required for PDSCH / PUSCH transmission based on the time-frequency resource occupancy of the first PDSCH / PUSCH in the corresponding slot. Using N as a reference, the time-frequency resources occupied by the PUSCH / PDSCH transmitted in other slots are determined. When the total amount of time-frequency resources occupied by the PDSCH / PUSCH is greater than the carrying capacity of one SBFD slot, the terminal determines the total amount of time-frequency resources occupied by its PDSCH / PUSCH in M ​​consecutive SBFD slots, that is, one TBS is transmitted in the DL subband or UL subband of M consecutive SBFD slots.

[0593] In this embodiment, it is assumed that the first PUSCH transmission of PUSCH occurs in a non-SBFD slot, that is, in a UL slot or a flexible slot. Specifically, take the aforementioned TDD UL-DL time slot structure and UL subband configuration as an example. Assume that the number of repeated PUSCH transmissions is R=4, and the first PUSCH is transmitted in slot#4. In this embodiment, it is assumed that the PUSCH is scheduled through DCI. The DCI has only one FDRA and TDRA domain for one PUSCH on a cell. Assume that the UL subband occupies 20 RBs in the frequency domain and occupies the entire slot in the time domain.

[0594] In this embodiment, it is assumed that the time-frequency resources occupied by the first PUSCH indicated by the base station are: 40 RBs in the frequency domain and 14 OFDM symbols in the time domain. It can be seen that the frequency domain resources occupied by the PUSCH exceed the frequency domain resources included in the UL subband.

[0595] Based on the above resource allocation, the terminal and base station determine time-frequency resources consisting of 40*14 RBs within the UL subband. In this embodiment, the PUSCH occupies 24 OFDM symbols in the time domain and 20 RBs in the frequency domain within the SBFD slot. This ensures that each PUSCH repetition occupies the same total time-frequency resources in both the SBFD and non-SBFD slots, allowing full reuse of the same MCS level and TBS.

[0596] Of course, this patent does not impose any restrictions on any TDD configuration and any UL subband.

[0597] Furthermore, in order to determine the starting position of the time-frequency resources occupied by the PUSCH in the SBFD slot, the following method can be used to determine it:

[0598] For the starting resource position in the frequency domain (ie, the starting RB index),

[0599] It is determined in a manner predefined in the protocol, for example, the frequency domain starting position of the UE in the UL subband is determined according to the UE ID or C-RNTI, or the RB with the largest index or the RB with the smallest index contained in the UL subband.

[0600] Alternatively, the FDRA field is reparsed (type1RA), that is, the SLIV indicated by the FDRA field is parsed to obtain S, and S is modulo the number of RBs included in the UL subband to finally obtain its starting frequency domain position within the UL subband range.

[0601] Alternatively, the starting frequency domain position in the SBFD slot is determined by RRC signaling configuration.

[0602] For the time domain starting position, that is, the starting OFDM symbol index

[0603] It is determined in a manner predefined in the protocol, for example, the time domain starting position of the UE in the SBFD slot is determined according to the UE ID or C-RNTI, or is OFDM symbol #0.

[0604] Alternatively, the starting OFDM symbol is still determined according to TDRA

[0605] Alternatively, the starting OFDM symbol is determined according to the TDRA and the number of symbols it occupies in the SBFD slot.

[0606] The size of the frequency domain resources and the size of the time domain resources are converted using the aforementioned method.

[0607] In Example 3, the prerequisites are the same as those in Example 1. Case 1 is shown in FIG5A , and Case 2 is shown in FIG5B .

[0608] In this embodiment, the frequency domain resources occupied by the repeatedly transmitted or periodically transmitted PUSCH in the SBFD slot and the non-SBFD slot are determined by the following method, thereby saving FDRA indication information, improving the flexibility of PUSCH scheduling, configuration and transmission, and improving the system uplink performance.

[0609] For example, as shown in Figure 6C, the terminal determines the frequency domain resource allocation for the SBFD slot and the non-SBFD slot respectively according to the FDRA indication field. When the frequency domain resource range allocated by the base station exceeds the subband range, the terminal adjusts the MCS level and / or TBS size expected in the slot.

[0610] When the frequency domain resource allocation type is RA type 0, the UE determines the RBG used for data channel transmission according to the bitmap.

[0611] When the frequency domain resource allocation type is RA type 1, the UE independently parses SLIV within the active BWP and subband range to determine S and L.

[0612] Specifically, the terminal transmits the PUSCH only within the UL subband range of a slot.

[0613] In this embodiment, it is assumed that the first PUSCH transmission of PUSCH occurs in a non-SBFD slot, that is, in a UL slot or a flexible slot. Specifically, take the aforementioned TDD UL-DL time slot structure and UL subband configuration as an example. Assume that the number of repeated PUSCH transmissions is R=4, and the first PUSCH is transmitted in slot#4. In this embodiment, it is assumed that the PUSCH is scheduled through DCI. The DCI has only one FDRA and TDRA domain for one PUSCH on a cell. Assume that the UL subband occupies 20 RBs in the frequency domain and occupies the entire slot in the time domain.

[0614] In this embodiment, it is assumed that the time-frequency resources occupied by the first PUSCH indicated by the base station are: 40 RBs in the frequency domain and 7 OFDM symbols in the time domain. It can be seen that the frequency domain resources occupied by the PUSCH exceed the frequency domain resources included in the UL subband.

[0615] According to the above resource allocation, the terminal and the base station determine the time-frequency domain resources containing 40*7 RBs in the UL subband. In this embodiment, the time-frequency domain resources occupied by the PUSCH in the SBFD slot are 7 OFDM symbols in the time domain and 20 RBs in the frequency domain. Assuming that the base station indicates that the MCS level of the PUSCH in the non-SBFD slot is MCS#4, the MCS level used for the PUSCH repetition transmitted in the SBFD slot is MCS#10. The MCS used in the non-SBFD slot and the SBFD slot can be determined according to a predefined method, or determined according to the relevant MCS offset configured by the RRC, or determined according to the indication information in the DCI. This patent does not impose any restrictions.

[0616] In this embodiment, the method for determining the time-frequency resources of PUSCH repetition in the SBFD slot is as described in Embodiment 1 to Embodiment 2, and will not be repeated here.

[0617] In Example 4, the methods described in Examples 1-3 can be applied to PDSCHs transmitted simultaneously in SBFD slots and non-SBFD slots, such as PDSCHs with slot aggregation enabled or semi-persistent scheduling (SPS) PDSCHs. The specific methods are as described in Examples 1-3 and are not repeated in this example.

For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods.
