The present application does not limit the specific implementation method. For example, predefined can refer to information defined in a protocol.

[0070] In the embodiments of the present application, "protocol" may refer to a standard protocol in the field of communications, for example, it may include an LTE protocol, a NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0071] Next, we will introduce SubBand non-overlapping Full Duplex (SBFD):

[0072] To overcome the problems of weak uplink coverage, long uplink latency, and insufficient uplink capacity caused by limited uplink (UL) resource allocation in Time Division Duplexing (TDD) technology, SBFD technology was proposed. SBFD technology allows data to be simultaneously transmitted and received on different subbands within the same subframe, time slot, or symbol. SBFD is primarily used on the network equipment side, while the user equipment (UE) side maintains its current state, specifically only transmitting or receiving data within the same subframe, time slot, or symbol. SBFD is also known as Cross Division Duplex (XDD) technology.

[0073] Exemplarily, the SBFD technology, as shown in Figure 1, configures a portion of the frequency domain resources corresponding to a downlink (DL) time domain unit as an uplink subband. As shown in Figure 1(a), the middle subband of the frequency domain resources corresponding to a DL time domain unit is configured as an uplink subband. Alternatively, as shown in Figure 1(b), the upper subband of the frequency domain resources corresponding to a DL time domain unit is configured as an uplink subband.

[0074] Generally speaking, SBFD operations meet the following requirements:

[0075] SBFD operates within one TDD carrier.

[0076] The SBFD solution is designed within a single uplink and downlink BWP pair with aligned center frequencies.

[0077] In a TDD carrier, an SBFD symbol (including a traditional uplink symbol) has at most one uplink subband. This uplink subband can be located in the middle of the TDD carrier or on both sides of the TDD carrier.

[0078] Furthermore, to maintain compatibility with symbol-level TDD uplink and downlink configurations, a time slot is allowed to include both SBFD symbols and non-SBFD symbols. Figure 2 shows a time slot diagram provided by related art. A portion of the frequency domain resources corresponding to the downlink symbols (D) and flexible symbols (F) in a time slot shown in Figure 2 is configured as an uplink subband.

[0079] Frequent switching between SBFD and non-SBFD symbols can increase implementation complexity and cause transmission interruptions. To avoid frequent SBFD symbol switching, a TDD cycle is specified to contain at most two transition points: one from a non-SBFD symbol to an SBFD symbol, and the other from an SBFD symbol to a non-SBFD symbol. For example, the transition point is between symbols 8 and 9 in Figure 2. A transition point can be at a slot boundary or within a slot.

[0080] PUCCH resources are generally configured at the upper and lower edges of the channel bandwidth, which can avoid uplink resource fragmentation and utilize other resources to transmit PUSCH. Therefore, if the above configuration rules are still followed, the location of PUCCH resource configuration will be different for SBFD time slots (time slots that only include SBFD symbols) and non-SBFD time slots (time slots that only include non-SBFD symbols). In addition, the interference encountered by the uplink is different for SBFD symbols and non-SBFD symbols, so the uplink quality is different, and the number and direction of the transmitting and receiving antennas / panels may also be different, which also leads to different resources, power control and other parameters for PUCCH transmission on SBFD symbols and non-SBFD symbols. Therefore, whether and how to configure resources, frequency hopping parameters, power control parameters, and spatial beam parameters for SBFD symbols and non-SBFD symbols separately is an urgent problem to be solved.

[0081] Next, the Physical Uplink Control Channel (PUCCH) is introduced:

[0082] PUCCH-related parameters are configured through PUCCH configuration (PUCCH-Config). PUCCH-related parameters include at least one of the following:

[0083] PUCCH resource set and PUCCH resources, including time domain resources (startingSymbolIndex, nrofSymbols), frequency domain resources (startingPRB, secondHopPRB), maximum code rate (maxCodeRate), orthogonal cover code (OCC) parameters, etc.

[0084] Physical Downlink Shared Channel (PDSCH) to HARQ-ACK time offset configuration: dl-DataToUL-ACK;

[0085] Scheduling request configuration: SchedulingRequestResourceConfig;

[0086] PUCCH spatial parameter configuration: PUCCH-SpatialRelationInfo;

[0087] PUCCH power control configuration: PUCCH-PowerControl.

[0088] The time domain position of the PUCCH is determined by determining the time domain position of the PUCCH based on the time domain position of the PDSCH and the time domain offset between the PDSCH and the HARQ-ACK.

[0089] Figure 3 shows a schematic diagram of a method for determining PUCCH resources provided by related technologies. K PUCCH resource sets are configured, where K is a positive integer, and the number of uplink control information (UCI) bits carried by each PUCCH resource set is different. Taking K=4 as an example, four PUCCH resource sets are configured: set 0, set 1, set 2, and set 3, and each set may include the same or different PUCCH formats. As shown in Figure 3, the number of UCI bits carried by set 0 is 2 bits, the number of UCI bits carried by set 1 is N2-2 bits, the number of UCI bits carried by set 2 is N3-N2 bits, and the number of UCI bits carried by set 3 is 1706-N3 bits, where N2 and N3 are pre-configured values. A PUCCH resource set is determined from the K PUCCH resource sets based on the number of UCI bits to be transmitted, and then a PUCCH resource is determined from the set based on the PUCCH Resource Indicator (PRI) in the DCI.

[0090] Figure 4 shows a schematic diagram of a mobile communication system provided by an exemplary embodiment of the present application. The mobile communication system includes a network device 110 and a terminal device 120, and may or may not include a terminal device 130, which is not limited in the present application.

The term "gNB" refers to a base station (B, gNB) or a transmission point (TRP or TP), or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DU), or a base station in a Beyond Fifth Generation (B5G) or a 6th Generation (6G) mobile communication system, or a core network (CN), fronthaul, backhaul, radio access network (RAN), network slicing, or a serving cell, primary cell (PCell), primary secondary cell (PSCell), special cell (SpCell), secondary cell (SCell), or neighboring cell of a terminal device.

[0093] In some embodiments, the network device 110 and the terminal device 120 communicate with each other via some air interface technology, such as a Uu interface.

[0094] For example, there are two communication scenarios between network device 110 and terminal device 120: uplink communication scenario and downlink communication scenario. Uplink communication, or uplink transmission, refers to sending signals or data to network device 110; downlink communication, or downlink transmission, refers to sending signals or data to terminal device 120.

[0095] In some embodiments, the terminal device 120 and the terminal device 130 communicate with each other via some air interface technology, such as a PC5 interface.

The first side communication scenario refers to terminal device 120 sending a signal to terminal device 130, while the second side communication scenario refers to terminal device 130 sending a signal to terminal device 120.

[0097] In some embodiments, terminal device 120 and terminal device 130 are both within the network coverage and located in the same cell, or terminal device 120 and terminal device 130 are both within the network coverage but located in different cells, or terminal device 120 is within the network coverage but terminal device 130 is outside the network coverage.

[0098] In some embodiments of the present application, "NR" may also be referred to as a 5G NR system or a 5G system. A 5G mobile communication system may include a non-standalone (NSA) network and / or a standalone (SA) network.

[0100] The mobile communication system provided in the embodiment of the present application can be applied to but not limited to at least one of the following communication scenarios: an uplink communication scenario, a downlink communication scenario, and a sidelink communication scenario.

[0101] For a timeslot containing both SBFD and non-SBFD symbols, determining the uplink channel resources presents the following issues, using the PUCCH as an example:

[0102] Question 1: Because the PUCCH resource is determined by first determining the time slot where the HARQ-ACK is located through the PDSCH to HARQ-ACK time domain offset configuration indication in the DCI, and then indicating a PUCCH resource in the above time slot through the PRI in the DCI, when there are both SBFD symbols and non-SBFD symbols in a time slot, before reading the PRI in the DCI, it is not known whether the indicated PUCCH resource is located in the SBFD symbol or the non-SBFD symbol. Figure 5 shows a schematic diagram of determining PUCCH resources provided by an exemplary embodiment of the present application. Assuming that PUCCH resource set 1 is configured for SBFD symbols and PUCCH resource set 2 is configured for non-SBFD symbols, the first horizontally filled square in Figure 5 is the first PUCCH resource in PUCCH resource set 1, and the second horizontally filled square is the first PUCCH resource in PUCCH resource set 2. For a terminal device, assuming that the PRI value in the received DCI is 000, which is used to indicate the first PUCCH resource, the terminal device cannot determine which PUCCH resource set the first PUCCH resource belongs to, PUCCH resource set 1 or PUCCH resource set 2. In other words, both PUCCH resources located in SBFD symbols and PUCCH resources located in non-SBFD symbols may be PUCCH resources that the network device wants to indicate.

[0103] Question 2: In a time slot with both SBFD symbols and non-SBFD symbols, if only one PUCCH resource is supported for transmission, or at least two PUCCH resources overlap, the terminal device multiplexes the uplink control information (UCI) carried by at least two PUCCH resources in the above time slot into one PUCCH for transmission. Then, whether the multiplexed PUCCH is determined from the PUCCH resource corresponding to the SBFD symbol or from the PUCCH resource corresponding to the non-SBFD symbol is also a problem that needs to be solved.

[0104] An embodiment of the present application provides a method for determining uplink channel resources. FIG6 shows a flow chart of a method for determining uplink channel resources provided by an exemplary embodiment of the present application, the method being executed by a terminal device, and comprising:

[0105] Step 610: Determine a target uplink channel resource among the uplink channel resources configured in the first configuration or the second configuration.

[0106] The first configuration and the second configuration are used to configure relevant parameters of the uplink channel resources, the first configuration corresponds to the first type of time domain resources, and the second configuration corresponds to the second type of time domain resources.

[0107] In some embodiments, uplink channel resources include at least one of the following: PUCCH resources, physical uplink shared channel (PUSCH) resources, physical random access channel (PRACH) resources, etc. The embodiments of the present application are not limited to this, and PUCCH resources are used as an example for illustration. The PUCCH resources in the embodiments of the present application are all illustrative examples and can be upgraded to uplink channel resources.

[0108] In some embodiments, the time domain resources include at least one of the following: a symbol, a symbol group, a time slot, a sub-time slot, a frame, and a subframe. In the embodiments of the present application, the specific type of time domain resources is not limited. For example, the first configuration corresponds to a first type of symbol, and the second configuration corresponds to a second type of symbol. For example, the first configuration corresponds to an SBFD symbol, and the second configuration corresponds to a non-SBFD symbol. An SBFD symbol is a symbol that includes at least one of an uplink subband, a downlink subband, and a guard band, while a non-SBFD symbol is a symbol that does not include any of the above subbands.

[0109] In some embodiments, the method is applicable to a time unit comprising a first type of time domain resource and a second type of time domain resource. Exemplarily, the first type of time domain resource is an SBFD symbol, the second type of time domain resource is a non-SBFD symbol, and the time unit is a mixed symbol slot comprising both SBFD and non-SBFD symbols.

[0110] In some embodiments, the first configuration is applicable to time slots in which all symbols are SBFD symbols, and also to time slots in which some symbols are SBFD symbols; the second configuration is applicable to time slots in which all symbols are non-SBFD symbols, and also to time slots in which some symbols are non-SBFD symbols.

[0111] For illustration, using the uplink channel resource as a PUCCH resource as an example, Figure 7 shows a schematic diagram of PUCCH resources provided by an exemplary embodiment of the present application. Taking the PUCCH resources in a time slot as an example, at the frequency domain location of the first configuration, seven PUCCH resources are configured, each occupying two symbols; at the frequency domain location of the second configuration, seven PUCCH resources are configured, each occupying two symbols. The first and second configurations share the same time domain resource parameters and can be applied to time slots with different symbol types. For example, when the slot only includes SBFD symbols, the target PUCCH resources are determined among the 7 PUCCH resources located in the middle position configured by the first configuration; when the slot only includes non-SBFD symbols, the target PUCCH resources are determined among the 7 PUCCH resources located in the upper position configured by the second configuration; when the slot includes SBFD symbols and non-SBFD symbols, taking the example that SBFD symbols occupy 8 symbols and non-SBFD symbols occupy 6 symbols, the first configuration is used to determine the target PUCCH resource in the SBFD symbol (one of the first 4 shaded blocks in the figure); and the second configuration is used to determine the target PUCCH resource in the non-SBFD symbol (one of the last 3 shaded blocks in the figure).

[0112] In some embodiments, the first configuration and the second configuration share time domain resource parameters. For example, as shown in FIG8 , the first configuration (PUCCH configuration 1) includes at least one of the following: frequency domain resource parameter 1, maximum code rate 1, OCC parameter 1, etc.; the second configuration (PUCCH configuration 2) includes at least one of the following: frequency domain resource parameter 2, maximum code rate 2, OCC parameter 2, etc.; the embodiment of the present application uses the first configuration and the second configuration to share time domain parameters as an example. Among them, frequency domain resource parameter 1 and frequency domain resource parameter 2 are usually different, maximum code rate 1 and maximum code rate 2 can be the same or different, and OCC parameter 1 and OCC parameter 2 can be the same or different. The shared time domain resource parameters can be additionally configured by the network device or agreed upon by the communication protocol.

[0113] In some embodiments, the first configuration and the second configuration do not share time domain resource parameters. For example, as shown in FIG9 , at the frequency domain position of the first configuration, there are 7 PUCCH resources, each of which occupies 2 symbols; at the frequency domain position of the second configuration, there are 7 PUCCH resources, each of which occupies 1 symbol. As shown in FIG10 , the first configuration (PUCCH configuration 1) includes at least one of the following: frequency domain resource parameter 1, time domain resource parameter 1, maximum code rate 1, OCC parameter 1, etc.; the second configuration (PUCCH configuration 2) includes at least one of the following: frequency domain resource parameter 2, time domain resource parameter 2, maximum code rate 2, OCC parameter 2, etc. Among them, time domain resource parameter 1 and time domain resource parameter 2 are different. The first configuration or the second configuration can also be a PUCCH configuration (PUCCH-Config), a PUCCH resource set (PUCCH-ResourceSet), or a PUCCH resource (PUCCH-resource).

[0114] In some embodiments, the target uplink channel resource is a resource used to send uplink control information (UCI). In some embodiments, the target uplink channel resource is a resource used to feedback HARQ-ACK or a HARQ-ACK codebook; in some embodiments, the target uplink channel resource is a resource used when at least two UCIs are multiplexed.

[0115] In some embodiments, determining the target uplink channel resource includes at least one of the following methods:

[0116] Method 1: Determine the configuration (first configuration or second configuration) corresponding to the target uplink channel resource according to the time domain resources occupied by the target uplink channel resource.

[0117] Taking the target uplink channel resource as a resource for feedback of HARQ-ACK or HARQ-ACK codebook as an example, the resource index and / or time domain resource of the target uplink channel resource is indicated by DCI, such as by the PRI field of DCI. After determining the time domain resource occupied by the target uplink channel resource based on the DCI, the first configuration or the second configuration is selected based on the time domain resource occupied by the target uplink channel resource to determine other configuration parameters of the target uplink channel resource other than the time domain resource parameters.

[0118] In some embodiments, when the time domain resources occupied by the target uplink channel resources are first type time domain resources, the target uplink channel resources are determined among the uplink channel resources configured by the first configuration; when the time domain resources occupied by the target uplink channel resources are second type time domain resources, the target uplink channel resources are determined among the uplink channel resources configured by the second configuration.

[0119] Taking the uplink channel resource as the PUCCH resource as an example, Figure 11 shows a schematic diagram of determining the target PUCCH resource provided by an exemplary embodiment of the present application. Referring to Figure 11, if the terminal device receives DCI 1, the DCI 1 schedules the transmission of PDSCH 1. Based on the time domain offset from PDSCH to HARQ-ACK, time slot 1 is determined after PDSCH 1. Assume that the value of PRI in DCI 1 is 010, which is used to indicate the third PUCCH resource. The symbol occupied by the third PUCCH resource is an SBFD symbol, and the SBFD symbol is associated with the first configuration. The terminal device determines the frequency domain parameters and other parameters (transmit power, maximum code rate, OCC parameters, etc.) of the third PUCCH resource based on the first configuration. Since the third PUCCH resource included therein occupies the same time domain symbol regardless of whether the first configuration or the second configuration is used, the time domain symbol type of the target PUCCH resource is first determined, and then the first configuration or the second configuration is determined based on the time domain symbol type. Figure 12 shows a schematic diagram of determining the target PUCCH resource provided by an exemplary embodiment of the present application. Referring to Figure 12, if the terminal device receives DCI 2, the DCI 2 schedules the transmission of PDSCH 2. Based on the time domain offset from PDSCH to HARQ-ACK, time slot 2 is determined after PDSCH 2. Assume that the value of PRI in DCI 2 is 110, which is used to indicate the 7th PUCCH resource. The symbol occupied by the 7th PUCCH resource is a non-SBFD symbol, and the non-SBFD symbol is associated with the second configuration. The terminal device then determines the frequency domain parameters and other parameters (transmit power, maximum code rate, OCC parameters, etc.) of the 7th PUCCH resource based on the second configuration.

[0120] Determining the target uplink channel resource in the first configuration or the second configuration based on the time domain resources occupied by the target uplink channel resource is simple to implement, can reduce the amount of calculation and power consumption of the terminal device, and improve the efficiency of determining the target uplink channel resource.

[0121] In some embodiments, determining relevant parameters of the target uplink channel resource according to the time domain resources occupied by the target uplink channel resource is determined according to the first configuration or the second configuration.

[0122] Exemplarily, if the target PUCCH resource occupies an SBFD symbol, then all or part of the relevant parameters of the target PUCCH resource are determined according to the first configuration; if the target PUCCH resource occupies a non-SBFD symbol, then all or part of the relevant parameters of the target PUCCH resource are determined according to the second configuration.

[0123] In some embodiments, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), orthogonal cover code (Orthogonal Cover Code, OCC) parameters, time domain resource parameters (e.g., starting symbol index startingSymbolIndex, number of symbols nrofSymbols).

[0124] In some embodiments, in the first configuration and the second configuration, the time domain resource configuration corresponding to the associated uplink channel resources is the same. In this case, the relevant parameters determined for the target uplink channel resource according to the first configuration or the second configuration do not include the time domain resource parameter.

[0125] In some embodiments, the terminal device expects that the time domain resource configuration corresponding to the associated uplink channel resources in the first configuration and the second configuration is the same; and / or the terminal device does not expect that the time domain resource configuration corresponding to the associated uplink channel resources in the first configuration and the second configuration is different. That is, the time domain resource parameters are carried in the first configuration and the second configuration and are exactly the same in both configurations.

[0126] In some embodiments, the time domain resource configurations corresponding to the associated uplink channel resources do not need to be configured separately, so that regardless of which configuration the terminal device uses to determine the uplink channel resources, the time domain resources are the same. In some embodiments, the time domain resource parameters shared by the first and second configurations are additionally configured by the network device or agreed upon by the communication protocol. In this case, the time domain resource parameters are not included in the first and second configurations.

[0127] In some embodiments, the associated uplink channel resources correspond to the same uplink channel resource identifier; or, the two uplink channel resource identifiers corresponding to the associated uplink channel resources have a pre-agreed corresponding relationship.

[0128] In some embodiments, the uplink channel resources are PUCCH resources as an example, a first PUCCH resource set is configured in a first configuration, and a second PUCCH resource set is configured in a second configuration. The first PUCCH resource set and the second PUCCH resource set are from different configurations, but there are associated PUCCH resources in the two PUCCH resource sets.

[0129] In some embodiments, uplink channel resources corresponding to the same uplink channel resource identification (IDentification, ID) are associated. The uplink channel resource is an example of a PUCCH resource. Referring to part (a) of FIG13 , for example, in a first PUCCH resource set, there are 7 PUCCH resources whose PUCCH resource IDs are 1, 2, 3, 4, 5, 6, and 7, respectively, and in a second PUCCH resource set, there are 7 PUCCH resources whose PUCCH resource IDs are 1, 2, 3, 4, 5, 6, and 7, respectively. The PUCCH resources whose corresponding PUCCH resource IDs are all 1 are associated PUCCH resources, and the PUCCH resources whose corresponding PUCCH resource IDs are all 2 are associated PUCCH resources, and so on; or,

[0130] The uplink channel resources of two uplink channel resource IDs with a pre-agreed corresponding relationship are associated. The uplink channel resource is an example of a PUCCH resource. Referring to part (b) of FIG13 , for example, in the first PUCCH resource set, the 7 PUCCH resources whose PUCCH resource IDs are 1, 2, 3, 4, 5, 6, and 7 are respectively, and in the second PUCCH resource set, the 7 PUCCH resources whose PUCCH resource IDs are 8, 9, 10, 11, 12, 13, and 14 are respectively, it is pre-agreed that the PUCCH resource with a PUCCH resource ID of 1 is associated with the PUCCH resource with a PUCCH resource ID of 8, and the PUCCH resource with a PUCCH resource ID of 2 is associated with the PUCCH resource with a PUCCH resource ID of 1. The source is associated with the PUCCH resource with PUCCH resource ID 9, the PUCCH resource with PUCCH resource ID 3 is associated with the PUCCH resource with PUCCH resource ID 10, the PUCCH resource with PUCCH resource ID 4 is associated with the PUCCH resource with PUCCH resource ID 11, the PUCCH resource with PUCCH resource ID 5 is associated with the PUCCH resource with PUCCH resource ID 12, the PUCCH resource with PUCCH resource ID 6 is associated with the PUCCH resource with PUCCH resource ID 13, and the PUCCH resource with PUCCH resource ID 7 is associated with the PUCCH resource with PUCCH resource ID 14.

[0131] In some embodiments, a candidate PUCCH resource of the target PUCCH resource is indicated by a PUCCH Resource Indicator (PRI) (one is further selected according to the first configuration or the second configuration). For example, when the PRI value is 000, it indicates that the target PUCCH resource is a PUCCH resource with a PUCCH resource ID of 1 or a PUCCH resource with a PUCCH resource ID of 8; when the PRI value is 001, it indicates that the target PUCCH resource is a PUCCH resource with a PUCCH resource ID of 2 or a PUCCH resource with a PUCCH resource ID of 9; when the PRI value is 010, it indicates that the target PUCCH resource is a PUCCH resource with a PUCCH resource ID of 3 or a PUCCH resource with a PUCCH resource ID of 10; When the value is 011, it indicates that the target PUCCH resource is the PUCCH resource with PUCCH resource ID 4 or the PUCCH resource with PUCCH resource ID 11; when the PRI value is 100, it indicates that the target PUCCH resource is the PUCCH resource with PUCCH resource ID 5 or the PUCCH resource with PUCCH resource ID 12; when the PRI value is 101, it indicates that the target PUCCH resource is the PUCCH resource with PUCCH resource ID 6 or the PUCCH resource ID 13; when the PRI value is 110, it indicates that the target PUCCH resource is the PUCCH resource with PUCCH resource ID 7 or the PUCCH resource ID 14.

[0132] The associated uplink channel resources may correspond to the same uplink channel resource identifier, or may be two uplink channel resource identifiers with a pre-agreed corresponding relationship, which can adapt to the association requirements of uplink channel resources in different situations.

[0133] In some embodiments, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), orthogonal cover code (OCC) parameters. The relevant parameters do not include time domain resource parameters, such as starting symbol index (startingSymbolIndex) and number of symbols (nrofSymbols). The time domain resource parameters are configured through other configurations, not through the first configuration or the second configuration.

[0134] When the relevant parameters do not include time domain resource parameters, they will be configured through other configurations, which is more flexible.

[0135] In some embodiments, the PUCCH resources used by at least one of the signals including the Scheduling Request (SR), Channel-State Information (CSI) report, and Semi-Persistent Scheduling Hybrid Automatic Repeat reQuest ACKnowledgment (SPS HARQ-ACK) corresponding to the first configuration are the PUCCH resources configured by the first configuration; the PUCCH resources used by at least one of the signals including the SR, CSI report, and SPS HARQ-ACK corresponding to the second configuration are the PUCCH resources configured by the second configuration.

[0136] In some embodiments, the relevant parameters of SR, CSI report, and SPS HARQ-ACK are configured in their respective corresponding configurations (first configuration or second configuration), for example, in their respective corresponding PUCCH configurations (PUCCH-Config).

[0137] Method 2: Determine the target uplink channel resource according to the instruction of the first DCI.

[0138] In some embodiments, the target uplink channel resource is a PUCCH resource used to feedback HARQ-ACK, and the HARQ-ACK is a HARQ-ACK of the PDSCH scheduled by the first DCI.

[0139] In some embodiments, the terminal device receives a first DCI, which is not only used to schedule the PDSCH but also used to indicate the first configuration or the second configuration used by the target PUCCH resource and the PRI corresponding to the target PUCCH resource.

[0140] In some embodiments, determining the target uplink channel resource in the uplink channel resources configured in the first configuration or the second configuration includes at least one of the following:

[0141] When the first DCI indicates a first configuration, the target uplink channel resource is determined from the uplink channel resources configured by the first configuration; when the first DCI indicates a second configuration, the target uplink channel resource is determined from the uplink channel resources configured by the second configuration; wherein the first DCI is used to indicate the target uplink channel resource. For example, the first DCI is also used to indicate the PRI corresponding to the target PUCCH resource.

[0142] Determining the target uplink channel resource according to the indication of the first DCI can improve the flexibility and accuracy of the target uplink channel resource indication.

[0143] In some embodiments, the first configuration or second configuration related parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), OCC parameters, time domain resource parameters (e.g., starting symbol index startingSymbolIndex, number of symbols nrofSymbols).

[0144] The first configuration or the second configuration may also be a PUCCH configuration (PUCCH-Config), a PUCCH resource set (PUCCH-ResourceSet), or a PUCCH resource (PUCCH-resource).

[0145] In some embodiments, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), and OCC parameters. The relevant parameters do not include time domain resource parameters, such as starting symbol index (startingSymbolIndex) and number of symbols (nrofSymbols). The time domain resource parameters are configured through other configurations, not through the first configuration or the second configuration.

[0146] In some embodiments, the manner in which the first DCI indicates the first configuration or the second configuration includes explicit indication and implicit indication.

[0147] Explicit instructions:

[0148] In some embodiments, the first DCI includes a first indication field, where the first indication field is used to indicate the first configuration or the second configuration.

[0149] In some embodiments, based on a DCI format known before the filing date, the first indication field is a newly added indication field, or part of the bits of a known indication field.

[0150] In some embodiments, the first indication field is an indication field added outside the uplink channel resource indication field, or the first indication field is part of the bits of the uplink channel resource indication field.

[0151] When the first indication field is a newly added indication field outside the uplink channel resource indication field, it can indicate the first configuration or the second configuration more flexibly; when the first indication field is a partial bit of the uplink channel resource indication field, such as the highest bit or the lowest bit of the PRI indication field, no additional DCI overhead is added.

[0152] In some embodiments, the first indication field is part of the bits of the uplink channel resource indication field, including: the first indication field is the highest bit or the lowest bit of the PRI indication field.

[0153] The highest bit or the lowest bit of the PRI indication field is used to indicate the first configuration or the second configuration, and the remaining bits in the PRI indication field are used to indicate the PUCCH resource in the first configuration or the second configuration. Figure 14 shows a schematic diagram of the PRI indication field provided by an exemplary embodiment of the present application. When the PRI indication field takes the value 011, the highest bit takes the value 0 to indicate the first configuration, and the remaining bits take the value 11 to indicate the fourth PUCCH resource in the first configuration.

[0154] In some embodiments, when the time domain resources include a sub-time domain resource type, the sub-time domain resource type is used to indicate the first configuration or the second configuration; when the time domain resources include at least two sub-time domain resource types, the first DCI includes a first indication field, and the first indication field is used to indicate the first configuration or the second configuration.

[0155] Exemplarily, when a time slot includes only one symbol type, the first configuration or the second configuration is determined by the symbol type, and all bits of the first indicator field (PRI indicator field) are used to indicate the PUCCH resource. When a time slot includes at least two symbol types, some bits in the first indicator field are used to indicate the first configuration or the second configuration, and the remaining bits are used to indicate the target PUCCH resource. As shown in Figure 7, when a time slot includes only SBFD symbols, the first configuration is determined by the symbol type. When a time slot includes only non-SBFD symbols, the second configuration is determined by the symbol type. When a time slot includes both SBFD and non-SBFD symbols, the highest bit in the first indicator field is used to indicate the first configuration or the second configuration, and the remaining bits are used to indicate the target PUCCH resource.

[0156] Implicit instructions:

[0157] In some embodiments, the DCI format of the first DCI is used to indicate the first configuration or the second configuration; or, the DCI format of the first DCI is associated with the first configuration or the second configuration; or, the Radio Network Temporary Identifier sequence (RNTI) used to scramble the first DCI is used to indicate the first configuration or the second configuration; or, the RNTI used to scramble the first DCI is associated with the first configuration or the second configuration; or, the resource position or resource index of the downlink control resource carrying the first DCI is used to indicate the first configuration or the second configuration; or, the resource position or resource index of the downlink control resource carrying the first DCI is associated with the first configuration or the second configuration.

[0158] Exemplarily, when the DCI format of the first DCI is format A, it is used to indicate the first configuration; when the DCI format of the first DCI is format B, it is used to indicate the second configuration. When the RNTI is the first RNTI, it is used to indicate the first configuration; when the RNTI is the second RNTI, it is used to indicate the second configuration.

[0159] For example, when the resource index is a control channel element (CCE) index, when the CCE index number is 1, it indicates the first configuration; when the CCE index number is 2, it indicates the second configuration. In one embodiment, the CCE index number may refer to the lowest CCE index number where the PDCCH is located, or the highest CCE index number where the PDCCH is located.

[0160] Indicating the first configuration or the second configuration in different ways can meet the needs of different scenarios without requiring additional DCI overhead.

[0161] Method 3: Determine the target uplink channel resources according to the instructions of the higher-layer signaling.

[0162] In some embodiments, the terminal device receives high-layer signaling, which is used to indicate the first configuration or the second configuration corresponding to the target uplink channel resource.

[0163] In some embodiments, when higher-layer signaling indicates a first configuration, the target uplink channel resource is determined among the uplink channel resources configured by the first configuration; and / or, when higher-layer signaling indicates a second configuration, the target uplink channel resource is determined among the uplink channel resources configured by the second configuration.

[0164] In some embodiments, the first configuration or the second configuration is used in a time unit including at least two types of time domain resources through high-layer signaling configuration. The time unit including at least two types of time domain resources can be a time slot including at least two types of symbols, referred to as a mixed-type time slot.

[0165] The upper layer refers to the protocol layer above the physical layer, such as the System Information Block (SIB), Radio Resource Control (RRC), and Media Access Control (MAC).

[0166] In some embodiments, the first configuration or second configuration related parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), OCC parameters, time domain resource parameters (e.g., starting symbol index startingSymbolIndex, number of symbols nrofSymbols).

[0167] The first configuration or the second configuration may also be a PUCCH configuration (PUCCH-Config), a PUCCH resource set (PUCCH-ResourceSet), or a PUCCH resource (PUCCH-resource).

[0168] In some embodiments, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), and OCC parameters. The relevant parameters do not include time domain resource parameters, such as starting symbol index (startingSymbolIndex) and number of symbols (nrofSymbols). The time domain resource parameters are configured through other configurations, not through the first configuration or the second configuration.

[0169] The high-level signaling configured by the network device can support a variety of configuration methods, be configured according to actual needs, and does not require additional DCI overhead. Take the uplink channel resource as an example to illustrate, the advantage of agreeing to use the first configuration is to ensure that the PUCCH resource falls within the valid uplink resource (valid UL resource), and the advantage of agreeing to use the second configuration is to avoid uplink resource fragmentation, while the link interference is relatively small. For example, in a time slot within a period of time, only SBFD symbols are included, and the network device instructs the terminal device to use the first configuration through high-level signaling; for another example, in a time slot within another period of time, only non-SBFD symbols are included, and the network device instructs the terminal device to use the second configuration through high-level signaling. For another example, the high-level signaling carries the window parameters of at least one time window and the correspondence between each time window and the first configuration or the second configuration, then the terminal device determines the first configuration or the second configuration to use for the current time window based on the above correspondence. The window parameters of the time window include: at least one of: starting position, ending position, length, cycle starting point, and cycle length.

[0170] Figure 15 shows a schematic diagram of a high-level signaling indication provided by an exemplary embodiment of the present application. The high-level signaling carries window parameters of the first time window and the second time window, and the first time window corresponds to the first configuration and the second time window corresponds to the second configuration. The starting position of the first time window is the starting position of the first symbol, and the length is 8 symbols; the starting position of the second time window is the starting position of the 9th symbol, and the length is 6 symbols. Taking the example of SBFD symbols occupying 8 symbols and non-SBFD symbols occupying 6 symbols, the first configuration is used in the SBFD symbol to determine the target PUCCH resource (one of the first 4 shaded blocks in the figure); the second configuration is used in the non-SBFD symbol to determine the target PUCCH resource (one of the last 3 shaded blocks in the figure).

[0171] Method 4: Determine the target uplink channel resources according to the communication protocol.

[0172] In some embodiments, when the first configuration is used based on the communication protocol agreement, the target uplink channel resource is determined among the uplink channel resources configured by the first configuration; when the second configuration is used based on the communication protocol agreement, the target uplink channel resource is determined among the uplink channel resources configured by the second configuration.

[0173] In some embodiments, according to a communication protocol, the first configuration or the second configuration is used in a time unit including at least two types of time domain resources. The time unit including at least two types of time domain resources can be a time slot including at least two types of symbols, referred to as a mixed type time slot.

[0174] In some embodiments, the first configuration or second configuration related parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), OCC parameters, time domain resource parameters (e.g., starting symbol index startingSymbolIndex, number of symbols nrofSymbols).

[0175] The first configuration or the second configuration may also be a PUCCH configuration (PUCCH-Config), a PUCCH resource set (PUCCH-ResourceSet), or a PUCCH resource (PUCCH-resource).

[0176] In some embodiments, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), and OCC parameters. The relevant parameters do not include time domain resource parameters, such as starting symbol index (startingSymbolIndex) and number of symbols (nrofSymbols). The time domain resource parameters are configured through other configurations, not through the first configuration or the second configuration.

[0177] The communication protocol stipulates that no network equipment configuration is required, and there is no additional DCI overhead. For example, using the PUCCH resource as the uplink channel resource, the advantage of using the first configuration is that it ensures that the PUCCH resource falls within the valid uplink resource (valid UL resource). The advantage of using the second configuration is that it avoids uplink resource fragmentation and reduces link interference.

[0178] For example, if a time slot within a certain period includes only SBFD symbols, the communication protocol stipulates the use of the first configuration. Another example is that a time slot within another period includes only non-SBFD symbols, and the communication protocol stipulates the use of the second configuration. In another example, if the communication protocol stipulates window parameters for at least one time window and a correspondence between each time window and the first or second configuration, the terminal device determines whether to use the first or second configuration for the current time window based on this correspondence. The window parameters of a time window include at least one of: a starting position, an ending position, a length, a period start point, and a period length.

[0179] In some embodiments, a UE is provided first and second for each of {PUCCH-ResourceSet,PUCCH-Resource except the startingSymbolIndex and nrofSymbols},respectively for use with PUCCH (SR, CSI, HARQ-ACK)occupying the first symbol type and the second symbol type respectively,where,the first symbol type and second symbol type are SBFD symbol type and non-SBFD symbol type.

[0180] In some embodiments, a first and a second configuration for each of {PUCCH-ResourceSet,PUCCH-Resource},respectively for use with PUCCH(SR,CSI,HARQ-ACK)occupying the first symbol type and the second symbol type respectively,where,the first symbol type and the second symbol type are SBFD symbol type and non-SBFD symbol type.UE expects that the corresponding PUCCH resource in the first config and the second config to occupy the same symbols.

[0181] In some embodiments, the terminal device is configured with a second configuration parameter and an offset value, the second configuration parameter corresponds to the second configuration, the offset value is a resource block (RB) offset (RB offset), and the RB offset is used to adjust the frequency domain resources of the PUCCH resources. Taking the first configuration corresponding to the SBFD symbol and the second configuration corresponding to the non-SBFD symbol as an example, the RB offset is the frequency domain offset of the PUCCH resource located in the SBFD symbol relative to the PUCCH resource located in the non-SBFD symbol.

[0182] In some embodiments, the terminal device is configured with a first configuration parameter and an offset value, the first configuration parameter corresponds to a first configuration, and the offset value is an RB offset. Taking the first configuration corresponding to SBFD symbols and the second configuration corresponding to non-SBFD symbols as an example, the RB offset is the frequency domain offset of the PUCCH resources located in the non-SBFD symbols relative to the PUCCH resources located in the SBFD symbols.

[0183] Figure 16 shows a schematic diagram of the PUCCH resource offset provided by an exemplary embodiment of the present application. Taking the case where the terminal device is configured with the second configuration parameter (PUCCH configuration 3) and the offset value, the offset value is an RB offset, the first configuration corresponds to the SBFD symbol, and the second configuration corresponds to the non-SBFD symbol as an example, the frequency domain resource parameters in PUCCH configuration 3 are added with the offset value and together with other resource parameters form PUCCH configuration 4.

[0184] Figure 17 shows a schematic diagram of a PUCCH resource offset provided by an exemplary embodiment of the present application. In some embodiments, the starting position of the PUCCH resource corresponding to the non-SBFD symbol is the configured starting RB, and the starting position of the PUCCH resource corresponding to the SBFD symbol is (startingPRB+RB_offset)mod(UL_subband size∩active UL BWP size), where startingPRB is the starting physical resource block, RB_offset is the RB offset, UL_subband size is the uplink subband size, active UL BWP size is the size of the activated uplink bandwidth portion, ∩ is the intersection operation, and mod is the remainder operation. The RBs occupied by the PUCCH resource located in the SBFD symbol are 1 RB starting from the starting position, or n RBs, where n is the number of PRBs parameter (nrofPRBs).

[0185] In some embodiments, the RB offset may be one RB offset, or a list of RB offsets, where each RB offset corresponds to one PUCCH resource or one PUCCH resource set.

[0186] In some embodiments, the terminal device receives a set of configuration parameters (PUCCH-Config), in which each PUCCH resource set includes N PUCCH resources, where N is twice the maximum number of PUCCH resources that can be configured in the current PUCCH resource set, wherein the first N / 2 PUCCH resources correspond to non-SBFD symbols, and the last N / 2 PUCCH resources correspond to SBFD symbols, or the first N / 2 PUCCH resources correspond to SBFD symbols, and the last N / 2 PUCCH resources correspond to non-SBFD symbols, and the first N / 2 PUCCH resources and the last N / 2 PUCCH resources share or do not share the time domain configuration.

[0187] In some embodiments, the terminal device receives a set of configuration parameters (PUCCH-Config), which includes M PUCCH resource sets, where the first M / 2 PUCCH resource sets correspond to non-SBFD symbols and the last M / 2 PUCCH resource sets correspond to SBFD symbols, or the first M / 2 PUCCH resource sets correspond to SBFD symbols and the last M / 2 PUCCH resource sets correspond to non-SBFD symbols, and the first M / 2 PUCCH resource sets and the last M / 2 PUCCH resource sets share or do not share the time domain configuration.

[0188] Figure 18 shows a schematic diagram of configuring PUCCH resources according to an exemplary embodiment of the present application. In a time slot, the first seven symbols are SBFD symbols, and the eighth to fourteenth symbols are non-SBFD symbols. In some embodiments, the first seven PUCCH resources in the PUCCH resource set are located at a first frequency domain location; the last seven PUCCH resources in the PUCCH resource set are located at a second frequency domain location.

[0189] In some embodiments, the information configured separately in the above method also includes at least one of the following in addition to PUCCH resources: PUCCH power control configuration parameters (PUCCH-PowerControl), PUCCH spatial configuration parameters (PUCCH-SpatialRelationInfo), SR configuration parameters (SchedulingRequestResourceConfig), etc.; the information shared by the above method also includes the time domain offset configuration (dl-DataToUL-ACK) from PDSCH to HARQ-ACK.

[0190] Method 5: Determine a target uplink channel resource, where the target uplink channel resource is an uplink channel resource used when at least two UCIs are multiplexed.

[0191] In some embodiments, the target uplink channel resource is an uplink channel resource used when at least two UCIs are multiplexed, and the at least two uplink channel resources corresponding to the at least two UCIs before multiplexing are in the same time unit, or the at least two uplink channel resources overlap.

[0192] In some embodiments, the first configuration or second configuration related parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), OCC parameters, time domain resource parameters (e.g., starting symbol index startingSymbolIndex, number of symbols nrofSymbols).

[0193] The first configuration or the second configuration may also be a PUCCH configuration (PUCCH-Config), a PUCCH resource set (PUCCH-ResourceSet), or a PUCCH resource (PUCCH-resource).

[0194] In some embodiments, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), and OCC parameters. The relevant parameters do not include time domain resource parameters, such as starting symbol index (startingSymbolIndex) and number of symbols (nrofSymbols). The time domain resource parameters are configured through other configurations, not through the first configuration or the second configuration.

[0195] The terminal device is about to transmit at least two uplink channel resources (carrying at least two UCIs) in the first time slot, and the at least two uplink channel resources overlap (partially or fully), or at least two uplink channel resources are in the same time unit (time slot, sub-time slot, symbol group, etc.), wherein the first time slot is a mixed symbol time slot type, that is, including SBFD symbols and non-SBFD symbols, then the terminal device multiplexes at least two UCIs in the target uplink channel resource for transmission, and the method for determining the target uplink channel resource includes at least one of the following:

[0196] Method 1: When at least two uplink channel resources correspond to the first configuration, the target uplink channel resource is determined among the uplink channel resources configured by the first configuration; when at least two uplink channel resources correspond to the second configuration, the target uplink channel resource is determined among the uplink channel resources configured by the second configuration.

[0197] Taking the uplink channel resource as an example, FIG19 shows a schematic diagram of determining PUCCH resources provided by an exemplary embodiment of the present application. Exemplarily, the first configuration indicates PUCCH resource set 1 and PUCCH resource set 2. Each PUCCH resource in PUCCH resource set 1 occupies 2 symbols, and each PUCCH resource in PUCCH resource set 2 occupies 4 symbols (not shown in the figure). Assuming that PUCCH1 and PUCCH2 both belong to PUCCH resource set 1, if at least two UCI multiplexed payloads correspond to PUCCH resource set 2, the target PUCCH resource is a PUCCH resource selected from PUCCH resource set 2.

[0198] Method 2: When at least two uplink channel resources correspond to the first configuration and the second configuration, the target uplink channel resource is determined among the uplink channel resources configured by the first configuration; or, when at least two uplink channel resources correspond to the first configuration and the second configuration, the target uplink channel resource is determined among the uplink channel resources configured by the second configuration.

[0199] Taking the uplink channel resource as an example, FIG20 shows a schematic diagram of determining PUCCH resources provided by an exemplary embodiment of the present application. Exemplarily, the first configuration indicates PUCCH resource set 1 and PUCCH resource set 2, with each PUCCH resource in PUCCH resource set 1 occupying 2 symbols and each PUCCH resource in PUCCH resource set 2 occupying 4 symbols (not shown in the figure). The second configuration indicates PUCCH resource set 3 and PUCCH resource set 4, with each PUCCH resource in PUCCH resource set 3 occupying 2 symbols and each PUCCH resource in PUCCH resource set 4 occupying 4 symbols (not shown in the figure).

[0200] Assume that PUCCH1 belongs to PUCCH resource set 1 and corresponds to the first configuration; and PUCCH2 belongs to PUCCH resource set 3 and corresponds to the second configuration. If the target PUCCH resource after multiplexing always uses the second configuration, and if at least two UCI multiplexed payloads correspond to PUCCH resource set 2 or 4, the target PUCCH resource is a PUCCH resource selected from PUCCH resource set 4.

[0201] If at least two PUCCH resources correspond to the first configuration and the second configuration, and the target PUCCH resource corresponds to the first configuration, taking the first configuration corresponding to the SBFD symbol as an example, the middle subband of the SBFD symbol can be configured as an uplink subband to ensure that the target PUCCH resource is within the valid uplink resource (valid UL resource); or, if at least two PUCCH resources correspond to the first configuration and the second configuration, and the target PUCCH resource corresponds to the second configuration, taking the second configuration corresponding to the non-SBFD symbol as an example, uplink resource fragmentation can be avoided while reducing link interference.

[0202] Mode 3: When at least two uplink channel resources correspond to the first configuration and the second configuration, and a dynamically scheduled first uplink channel resource is present among the at least two uplink channel resources, the target uplink channel resource is determined according to at least one of the following:

[0203] The time domain resource type corresponding to the first uplink channel resource; the configuration corresponding to the first uplink channel resource; and the DCI corresponding to the first uplink channel resource.

[0204] Case 1: determining the target uplink channel resource according to the time domain resource type corresponding to the first uplink channel resource.

[0205] In some embodiments, when at least two uplink channel resources correspond to a first configuration and a second configuration, a dynamically scheduled first uplink channel resource exists among the at least two uplink channel resources, and the first uplink channel resource is located in a first type of time domain resource, determining a target uplink channel resource among the uplink channel resources configured by the first configuration;

[0206] When at least two uplink channel resources correspond to a first configuration and a second configuration, there is a dynamically scheduled first uplink channel resource among the at least two uplink channel resources, and the first uplink channel resource is located in the second type of time domain resources, determine the target uplink channel resource among the uplink channel resources configured by the second configuration.

[0207] Taking the uplink channel resource as a PUCCH resource and the time domain resource as a symbol as an example, when the first PUCCH resource is located in an SBFD symbol, the target PUCCH resource is determined in the PUCCH resources configured by the first configuration; when the first PUCCH resource is located in a non-SBFD symbol, the target PUCCH resource is determined in the PUCCH resources configured by the second configuration.

[0208] FIG21 is a schematic diagram illustrating a method for determining PUCCH resources according to an exemplary embodiment of the present application. Assuming that at least two PUCCH resources are PUCCH 1 and PUCCH 2, and that PUCCH 1 corresponds to a first configuration and PUCCH 2 corresponds to a second configuration, the first PUCCH resource dynamically scheduled by DCI is PUCCH 1. When PUCCH 1 is located in an SBFD symbol, a target PUCCH resource is determined within the PUCCH resources configured in the first configuration. For example, a PUCCH resource set in the first configuration is determined based on the multiplexed payload of at least two UCIs, and the target PUCCH resource is determined within the PUCCH resource set.

[0209] Case 2: Determine the target uplink channel resource according to the configuration corresponding to the first uplink channel resource.

[0210] In some embodiments, when at least two uplink channel resources correspond to a first configuration and a second configuration, a dynamically scheduled first uplink channel resource exists among the at least two uplink channel resources, and the first uplink channel resource corresponds to the first configuration, determining a target uplink channel resource among the uplink channel resources configured by the first configuration;

[0211] When at least two uplink channel resources correspond to a first configuration and a second configuration, a dynamically scheduled first uplink channel resource exists among the at least two uplink channel resources, and the first uplink channel resource corresponds to the second configuration, a target uplink channel resource is determined among the uplink channel resources configured by the second configuration.

[0212] Continuing with Figure 21, assuming that at least two PUCCH resources are PUCCH 1 and PUCCH 2, and PUCCH 1 corresponds to a first configuration and PUCCH 2 corresponds to a second configuration, the first PUCCH resource dynamically scheduled by DCI is PUCCH 1. When PUCCH 1 corresponds to the first configuration, a target PUCCH resource is determined within the PUCCH resources configured in the first configuration. For example, a PUCCH resource set in the first configuration is determined based on the multiplexed payload of at least two UCIs, and the target PUCCH resource is determined within this PUCCH resource set.

[0213] Case three: determining the target uplink channel resource according to the DCI corresponding to the first uplink channel resource.

[0214] In some embodiments, when at least two uplink channel resources correspond to a first configuration and a second configuration, a dynamically scheduled first uplink channel resource exists among the at least two uplink channel resources, and the second DCI indicates the first configuration, determining a target uplink channel resource among the uplink channel resources configured by the first configuration; and / or,

[0215] When at least two uplink channel resources correspond to a first configuration and a second configuration, a dynamically scheduled first uplink channel resource exists among the at least two uplink channel resources, and a second DCI indicates the second configuration, a target uplink channel resource is determined among the uplink channel resources configured by the second configuration.

[0216] In the case where there is a dynamically scheduled first uplink channel resource among at least two uplink channel resources, the target uplink channel resource is determined according to the time domain resource type corresponding to the first uplink channel resource, or the configuration corresponding to the first uplink channel resource, or the DCI corresponding to the first uplink channel resource, which is more flexible and adaptable to the needs of different scenarios.

[0217] In some embodiments, the second indication field in the second DCI is used to indicate the first configuration or the second configuration; or, the DCI format in the second DCI is used to indicate the first configuration or the second configuration; or, the RNTI used to scramble the second DCI is used to indicate the first configuration or the second configuration; or, the resource location or resource index carrying the second DCI is used to indicate the first configuration or the second configuration.

[0218] Exemplarily, the second indication field indicates the first configuration or the second configuration through one bit. For example, when the bit value is 0, it indicates the first configuration, and when the bit value is 1, it indicates the second configuration.

[0219] When the DCI format of the second DCI is format A, it is used to indicate the first configuration; when the DCI format of the second DCI is format B, it is used to indicate the second configuration. When the RNTI is the first RNTI, it is used to indicate the first configuration; when the RNTI is the second RNTI, it is used to indicate the second configuration. When the resource index is a CCE index, when the CCE index number is 1, it is used to indicate the first configuration; when the CCE index number is 2, it is used to indicate the second configuration.

[0220] Through the above different indication methods, the first configuration or the second configuration can be accurately indicated in different situations.

[0221] If there are multiple dynamically scheduled first uplink channel resources, the configuration information corresponding to the target uplink channel resource is determined according to the indication of the last DCI among the multiple DCIs corresponding to the multiple dynamically scheduled first uplink channel resources, or is determined according to the configuration information corresponding to the uplink channel resource indicated by the last DCI.

[0222] That is, when at least two uplink channel resources correspond to the first configuration and the second configuration, there are at least two first uplink channel resources dynamically scheduled by at least two second DCIs among the at least two uplink channel resources, and the last DCI indicates the first configuration, determine the target uplink channel resource among the uplink channel resources configured by the first configuration;

[0223] When at least two uplink channel resources correspond to a first configuration and a second configuration, there are at least two first uplink channel resources dynamically scheduled by at least two second DCIs among the at least two uplink channel resources, and the last DCI indicates the second configuration, the target uplink channel resource is determined among the uplink channel resources configured by the second configuration.

[0224] The at least two second DCIs correspond one-to-one to the at least two first uplink channel resources, and the last DCI is the last one of the at least two second DCIs.

[0225] Taking the uplink channel resource as an example, FIG22 shows a schematic diagram of determining PUCCH resources provided by an exemplary embodiment of the present application. At least two PUCCH resources are PUCCH 1 and PUCCH 2. When PUCCH 1 corresponds to the first configuration and PUCCH 2 corresponds to the second configuration, DCI 1 indicates PUCCH 1, DCI 2 indicates PUCCH 2, and the second DCI is the last DCI, DCI 2. When DCI 2 indicates the first configuration and the PRI indication field value is 00, a target PUCCH resource set is determined from the multiple PUCCH resource sets indicated by the first configuration based on the multiplexed payloads of at least two UCIs. PUCCH 3 (target PUCCH resource) is the first PUCCH resource in the target PUCCH resource set. The multiple PUCCH resource sets correspond to different payloads or PUCCH formats.

[0226] In some embodiments, the terminal device does not expect that the configurations corresponding to at least two uplink channel resources are different; or, the terminal device expects that the configurations corresponding to at least two uplink channel resources are the same; or, the terminal device expects that at least two uplink channel resources both correspond to the first configuration; or, the terminal device expects that at least two uplink channel resources both correspond to the second configuration.

[0227] In some embodiments, the terminal device does not expect the target uplink channel resource to be configured or indicated by the network device, and the target uplink channel resource is in a time slot including both the first type of time domain resources and the second type of time domain resources.

[0228] In some embodiments, the configurations corresponding to the at least two uplink channel resources include a first configuration and / or a second configuration.

[0229] In some embodiments, the uplink channel resource is a PUCCH resource as an example. When the configurations corresponding to at least two PUCCH resources are different and the UCI corresponding to the at least two PUCCH resources are not multiplexed, two HARQ-ACK codebooks are constructed, HARQ-ACK codebook 1 corresponds to the first configuration, and HARQ-ACK codebook 2 corresponds to the second configuration.

[0230] Figure 23 shows a schematic diagram of transmitting a HARQ-ACK codebook according to an exemplary embodiment of the present application. DCI 1 schedules PUCCH 1 to transmit HARQ-ACK codebook 1, and DCI 2 schedules PUCCH 2 to transmit HARQ-ACK codebook 2. PUCCH 1 corresponds to the first PUCCH configuration, and PUCCH 2 corresponds to the second PUCCH configuration. In this case, the two codebooks are not multiplexed; PUCCH 1 continues to transmit HARQ-ACK codebook 1, and PUCCH 2 continues to transmit HARQ-ACK codebook 2.

[0231] In some embodiments, the method for determining uplink channel resources further includes: receiving a first configuration and a second configuration.

[0232] In some embodiments, a first configuration parameter and a second configuration parameter are received, the first configuration parameter corresponds to the first configuration, and the second configuration parameter corresponds to the second configuration; or, a first configuration parameter and an offset value are received, the first configuration parameter corresponds to the first configuration, and the configuration parameter after the first configuration parameter is offset based on the offset value corresponds to the second configuration; or, a group of configuration parameters are received, the group of configuration parameters includes a first configuration parameter and a second configuration parameter, the first configuration parameter corresponds to the first configuration, and the second configuration parameter corresponds to the second configuration.

[0233] The separate configuration in the above method includes configuring the first configuration parameter and the second configuration parameter separately; it also includes configuring the first configuration parameter, and the configuration parameter corresponding to the second configuration is obtained by offsetting the first configuration parameter based on the offset value; it also includes configuring a group of configuration parameters, which includes 2 parts, the first part of the parameters corresponds to the first configuration parameter, and the second part of the parameters corresponds to the second configuration parameter.

[0234] In some embodiments, the offset value is a resource block (RB) offset or an RB offset list. The RB offset is used to adjust the frequency domain resources of the PUCCH resources. Taking the first configuration corresponding to SBFD symbols and the second configuration corresponding to non-SBFD symbols as an example, the RB offset is the frequency domain offset of the PUCCH resources located in the SBFD symbols relative to the PUCCH resources located in the non-SBFD symbols, or the RB offset is the frequency domain offset of the PUCCH resources located in the non-SBFD symbols relative to the PUCCH resources located in the SBFD symbols.

[0235] To sum up, the method provided in this embodiment determines the target uplink channel resources among the uplink channel resources configured by the first configuration or the second configuration; wherein the first configuration and the second configuration are used to configure relevant parameters of the uplink channel resources, the first configuration corresponds to the first type of time domain resources, and the second configuration corresponds to the second type of time domain resources, so that the terminal device can use different configurations to determine the uplink channel resources to be used for different types of time domain resources.

[0236] FIG24 shows a flowchart of a method for determining uplink channel resources provided by an exemplary embodiment of the present application. The method is executed by a terminal device and includes:

[0237] Step 2410: Determine a target uplink channel resource among the uplink channel resources configured in at least one of the first configuration, the second configuration, and the third configuration.

[0238] Among them, the third configuration is used to configure the relevant parameters of the uplink channel resources in the time unit having the first type of time domain resources and the second type of time domain resources, the first configuration is used to configure the relevant parameters of the uplink channel resources in the time unit having (only) the first type of time domain resources, and the second configuration is used to configure the relevant parameters of the uplink channel resources in the time unit having (only) the second type of time domain resources.

[0239] In some embodiments, the third configuration in the method is applicable to a time unit including a first type of time domain resources and a second type of time domain resources.

[0240] In some embodiments, one of the first configuration, the second configuration, and the third configuration is determined according to the time unit where the target uplink channel resource is located; and the target uplink channel resource is determined among the uplink channel resources indicated by the configuration.

[0241] The target uplink channel resource is determined according to the time unit where the target uplink channel resource is located, which is simple to implement.

[0242] When the time unit where the target uplink channel resource is located is a first type of time domain resource, determining the target uplink channel resource in the uplink channel resources configured by the first configuration;

[0243] When the time unit where the target uplink channel resource is located is a second type of time domain resource, determining the target uplink channel resource in the uplink channel resources configured by the second configuration;

[0244] In a case where the time unit where the target uplink channel resource is located includes the first type of time domain resources and the second type of time domain resources, the target uplink channel resource is determined among the uplink channel resources configured by the third configuration.

[0245] Taking the first configuration, the second configuration and the third configuration corresponding to the first time slot type, the second time slot type and the third time slot type respectively as an example, the first time slot type is a time slot type that only includes SBFD symbols, the second time slot type is a time slot type that only includes non-SBFD symbols, and the third time slot type is a time slot type that includes both SBFD symbols and non-SBFD symbols.

[0246] In some embodiments, the uplink channel resources used by at least one of the SR, CSI report, and SPS HARQ-ACK signals corresponding to the first configuration are the uplink channel resources configured by the first configuration;

[0247] The uplink channel resources used by at least one of the SR, CSI report, and SPS HARQ-ACK signals corresponding to the second configuration are the uplink channel resources configured by the second configuration;

[0248] The uplink channel resources used by at least one of the SR, CSI report, and SPS HARQ-ACK signals corresponding to the third configuration are the uplink channel resources configured by the third configuration.

[0249] In some embodiments, the method further includes: receiving the first configuration and the third configuration; or, receiving the second configuration and the third configuration; or, receiving the first configuration, the second configuration, and the third configuration.

[0250] The specific implementation details of the receiving configuration are shown in the embodiment of FIG6 and will not be repeated here.

[0251] In summary, the method provided in this embodiment determines the target uplink channel resource by using the uplink channel resources configured by at least one of the first configuration, the second configuration, and the third configuration. The third configuration is used to configure the relevant parameters of the uplink channel resources in the time unit having the first type of time domain resources and the second type of time domain resources, the first configuration is used to configure the relevant parameters of the uplink channel resources in the time unit having (only) the first type of time domain resources, and the second configuration is used to configure the relevant parameters of the uplink channel resources in the time unit having (only) the second type of time domain resources, so that the terminal device can use different configurations to determine the uplink channel resources to be used for different types of time domain resources.

[0252] FIG25 shows a flowchart of a method for sending resource configuration provided by an exemplary embodiment of the present application. The method is executed by a network device and includes:

[0253] Step 2510: Send the first configuration and the second configuration.

[0254] The first configuration and the second configuration are used to configure relevant parameters of the uplink channel resources, the first configuration corresponds to the first type of time domain resources, and the second configuration corresponds to the second type of time domain resources.

[0255] In some embodiments, a first configuration parameter and a second configuration parameter are sent, the first configuration parameter corresponds to the first configuration, and the second configuration parameter corresponds to the second configuration; or, a first configuration parameter and an offset value are sent, the first configuration parameter corresponds to the first configuration, and the configuration parameter after the first configuration parameter is offset based on the offset value corresponds to the second configuration; or, a group of configuration parameters are sent, the group of configuration parameters includes the first configuration parameter and the second configuration parameter, the first configuration parameter corresponds to the first configuration, and the second configuration parameter corresponds to the second configuration.

[0256] The separate configuration in the above method includes configuring the first configuration parameter and the second configuration parameter separately; it also includes configuring the first configuration parameter, and the configuration parameter corresponding to the second configuration is obtained by offsetting the first configuration parameter based on the offset value; it also includes configuring a group of configuration parameters, which includes 2 parts, the first part of the parameters corresponds to the first configuration parameter, and the second part of the parameters corresponds to the second configuration parameter.

[0257] In some embodiments, the offset value is a resource block (RB) offset (RB offset), and the RB offset is used to adjust the frequency domain resources of the PUCCH resources. Taking the first configuration corresponding to SBFD symbols and the second configuration corresponding to non-SBFD symbols as an example, the uplink channel resources are PUCCH resources as an example for explanation. The RB offset is the frequency domain offset of the PUCCH resources located in the SBFD symbols relative to the PUCCH resources located in the non-SBFD symbols, or the RB offset is the frequency domain offset of the PUCCH resources located in the non-SBFD symbols relative to the PUCCH resources located in the SBFD symbols.

[0258] In some embodiments, the uplink channel resources include at least one of the following: PUCCH resources, physical uplink shared channel (PUSCH) resources, physical random access channel (PRACH) resources, etc. The embodiments of the present application are not limited to this, and generally use PUCCH resources as an example for description.

[0259] In some embodiments, the time domain resources include at least one of the following: a symbol, a symbol group, a time slot, a sub-time slot, a frame, and a subframe. In the embodiments of the present application, the specific type of time domain resources is not limited. For example, the first configuration corresponds to a first type of symbol, and the second configuration corresponds to a second type of symbol. For example, the first configuration corresponds to an SBFD symbol, and the second configuration corresponds to a non-SBFD symbol. An SBFD symbol is a symbol that includes at least one of an uplink subband, a downlink subband, and a guard band, while a non-SBFD symbol is a symbol that does not include any of the above subbands.

[0260] In some embodiments, the method is applicable to a time unit including a first type of time domain resources and a second type of time domain resources.

[0261] In some embodiments, the first configuration is applicable to time slots in which all symbols are SBFD symbols, and also to time slots in which some symbols are SBFD symbols; the second configuration is applicable to time slots in which all symbols are non-SBFD symbols, and also to time slots in which some symbols are non-SBFD symbols.

[0262] For illustration, using the uplink channel resource as a PUCCH resource as an example, Figure 7 shows a schematic diagram of PUCCH resources provided by an exemplary embodiment of the present application. Taking the PUCCH resources in a time slot as an example, at the frequency domain location of the first configuration, seven PUCCH resources are configured, each occupying two symbols; at the frequency domain location of the second configuration, seven PUCCH resources are configured, each occupying two symbols. The first and second configurations share the same time domain resource parameters and can be applied to time slots with different symbol types. For example, when the slot only includes SBFD symbols, the target PUCCH resources are determined among the 7 PUCCH resources located in the middle position configured by the first configuration; when the slot only includes non-SBFD symbols, the target PUCCH resources are determined among the 7 PUCCH resources located in the upper position configured by the second configuration; when the slot includes SBFD symbols and non-SBFD symbols, taking the example that SBFD symbols occupy 8 symbols and non-SBFD symbols occupy 6 symbols, the first configuration is used to determine the target PUCCH resource in the SBFD symbol (one of the first 4 shaded blocks in the figure); and the second configuration is used to determine the target PUCCH resource in the non-SBFD symbol (one of the last 3 shaded blocks in the figure).

[0263] In some embodiments, the first configuration and the second configuration share time domain resource parameters. For example, as shown in FIG8 , the first configuration (PUCCH configuration 1) includes at least one of the following: frequency domain resource parameter 1, maximum code rate 1, OCC parameter 1, etc.; the second configuration (PUCCH configuration 2) includes at least one of the following: frequency domain resource parameter 2, maximum code rate 2, OCC parameter 2, etc.; the embodiment of the present application uses the first configuration and the second configuration to share time domain parameters as an example. Among them, frequency domain resource parameter 1 and frequency domain resource parameter 2 are usually different, maximum code rate 1 and maximum code rate 2 can be the same or different, and OCC parameter 1 and OCC parameter 2 can be the same or different. The shared time domain resource parameters can be additionally configured by the network device or agreed upon by the communication protocol.

[0264] In some embodiments, the first configuration and the second configuration do not share time domain resource parameters. For example, as shown in FIG9 , at the frequency domain position of the first configuration, there are 7 PUCCH resources, each of which occupies 2 symbols; at the frequency domain position of the second configuration, there are 7 PUCCH resources, each of which occupies 1 symbol. As shown in FIG10 , the first configuration (PUCCH configuration 1) includes at least one of the following: frequency domain resource parameter 1, time domain resource parameter 1, maximum code rate 1, OCC parameter 1, etc.; the second configuration (PUCCH configuration 2) includes at least one of the following: frequency domain resource parameter 2, time domain resource parameter 2, maximum code rate 2, OCC parameter 2, etc. Among them, time domain resource parameter 1 and time domain resource parameter 2 are different. The first configuration or the second configuration can also be a PUCCH configuration (PUCCH-Config), a PUCCH resource set (PUCCH-ResourceSet), or a PUCCH resource (PUCCH-resource).

[0265] In some embodiments, the target uplink channel resource is a resource used to send uplink control information (UCI). In some embodiments, the target uplink channel resource is a resource used to feedback HARQ-ACK or a HARQ-ACK codebook; in some embodiments, the target uplink channel resource is a resource used when at least two UCIs are multiplexed.

[0266] In some embodiments, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), orthogonal cover code (Orthogonal Cover Code, OCC) parameters, time domain resource parameters (e.g., starting symbol index startingSymbolIndex, number of symbols nrofSymbols).

[0267] In some embodiments, in the first configuration and the second configuration, the time domain resource configuration corresponding to the associated uplink channel resources is the same. In this case, the relevant parameters determined for the target uplink channel resource according to the first configuration or the second configuration do not include the time domain resource parameter.

[0268] In some embodiments, the terminal device expects that the time domain resource configuration corresponding to the associated uplink channel resources in the first configuration and the second configuration is the same; and / or the terminal device does not expect that the time domain resource configuration corresponding to the associated uplink channel resources in the first configuration and the second configuration is different. That is, the time domain resource parameters are carried in the first configuration and the second configuration and are exactly the same in both configurations.

[0269] The network device will try to configure itself in accordance with the expectations of the terminal device, but it may not always do so. In some cases, the network device may send configuration information in a manner that the terminal device does not expect. In this case, this application does not limit how the terminal device handles the unexpected configuration information; for example, the terminal device may independently implement it.

[0270] In some embodiments, the time domain resource configurations corresponding to the associated uplink channel resources do not need to be configured separately, so that the time domain resources are the same regardless of which configuration the terminal device uses to determine the uplink channel resources.

[0271] In some embodiments, the time domain resource parameters shared by the first configuration and the second configuration are additionally configured by the network device or agreed upon by the communication protocol. In this case, the first configuration and the second configuration do not include the time domain resource parameters.

[0272] In some embodiments, the associated uplink channel resources correspond to the same uplink channel resource identifier; or, the two uplink channel resource identifiers corresponding to the associated uplink channel resources have a pre-agreed corresponding relationship.

[0273] In some embodiments, the uplink channel resources are PUCCH resources as an example, a first PUCCH resource set is configured in a first configuration, and a second PUCCH resource set is configured in a second configuration. The first PUCCH resource set and the second PUCCH resource set are from different configurations, but there are associated PUCCH resources in the two PUCCH resource sets.

[0274] In some embodiments, uplink channel resources having the same uplink channel resource identification (IDentification, ID) are associated. For example, the uplink channel resource is a PUCCH resource. Referring to part (a) of FIG13 , for example, in a first PUCCH resource set, the 7 PUCCH resources whose PUCCH resource IDs are 1, 2, 3, 4, 5, 6, and 7, respectively, and in a second PUCCH resource set, the 7 PUCCH resources whose PUCCH resource IDs are 1, 2, 3, 4, 5, 6, and 7, respectively, the PUCCH resources whose corresponding PUCCH resource IDs are all 1 are associated PUCCH resources, the PUCCH resources whose corresponding PUCCH resource IDs are all 2 are associated PUCCH resources, and so on; or,

[0275] The uplink channel resources of two uplink channel resource IDs with a pre-agreed corresponding relationship are associated. The uplink channel resource is an example of a PUCCH resource. Referring to part (b) of FIG13 , for example, in the first PUCCH resource set, the 7 PUCCH resources whose PUCCH resource IDs are 1, 2, 3, 4, 5, 6, and 7 are respectively, and in the second PUCCH resource set, the 7 PUCCH resources whose PUCCH resource IDs are 8, 9, 10, 11, 12, 13, and 14 are respectively, it is pre-agreed that the PUCCH resource with a PUCCH resource ID of 1 is associated with the PUCCH resource with a PUCCH resource ID of 8, and the PUCCH resource with a PUCCH resource ID of 2 is associated with the PUCCH resource with a PUCCH resource ID of 1. The source is associated with the PUCCH resource with PUCCH resource ID 9, the PUCCH resource with PUCCH resource ID 3 is associated with the PUCCH resource with PUCCH resource ID 10, the PUCCH resource with PUCCH resource ID 4 is associated with the PUCCH resource with PUCCH resource ID 11, the PUCCH resource with PUCCH resource ID 5 is associated with the PUCCH resource with PUCCH resource ID 12, the PUCCH resource with PUCCH resource ID 6 is associated with the PUCCH resource with PUCCH resource ID 13, and the PUCCH resource with PUCCH resource ID 7 is associated with the PUCCH resource with PUCCH resource ID 14.

[0276] In some embodiments, a candidate PUCCH resource of the target PUCCH resource is indicated by a PUCCH Resource Indicator (PRI) (one is further selected according to the first configuration or the second configuration). For example, when the PRI value is 000, it indicates that the target PUCCH resource is a PUCCH resource with a PUCCH resource ID of 1 or a PUCCH resource with a PUCCH resource ID of 8; when the PRI value is 001, it indicates that the target PUCCH resource is a PUCCH resource with a PUCCH resource ID of 2 or a PUCCH resource with a PUCCH resource ID of 9; when the PRI value is 010, it indicates that the target PUCCH resource is a PUCCH resource with a PUCCH resource ID of 3 or a PUCCH resource with a PUCCH resource ID of 10; When the value is 011, it indicates that the target PUCCH resource is the PUCCH resource with PUCCH resource ID 4 or the PUCCH resource with PUCCH resource ID 11; when the PRI value is 100, it indicates that the target PUCCH resource is the PUCCH resource with PUCCH resource ID 5 or the PUCCH resource with PUCCH resource ID 12; when the PRI value is 101, it indicates that the target PUCCH resource is the PUCCH resource with PUCCH resource ID 6 or the PUCCH resource ID 13; when the PRI value is 110, it indicates that the target PUCCH resource is the PUCCH resource with PUCCH resource ID 7 or the PUCCH resource ID 14.

[0277] The associated uplink channel resources may correspond to the same uplink channel resource identifier, or may be two uplink channel resource identifiers with a pre-agreed corresponding relationship, which can adapt to the association requirements of uplink channel resources in different situations.

[0278] In some embodiments, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), orthogonal cover code (OCC) parameters. The relevant parameters do not include time domain resource parameters, such as starting symbol index (startingSymbolIndex) and number of symbols (nrofSymbols). The time domain resource parameters are configured through other configurations, not through the first configuration or the second configuration.

[0279] When the relevant parameters do not include time domain resource parameters, they will be configured through other configurations, which is more flexible.

[0280] In some embodiments, the PUCCH resources used by at least one of the signals including the Scheduling Request (SR), Channel-State Information (CSI) report, and Semi-Persistent Scheduling Hybrid Automatic Repeat reQuest ACKnowledgment (SPS HARQ-ACK) corresponding to the first configuration are the PUCCH resources configured by the first configuration; the PUCCH resources used by at least one of the signals including the SR, CSI report, and SPS HARQ-ACK corresponding to the second configuration are the PUCCH resources configured by the second configuration.

[0281] In some embodiments, the relevant parameters of SR, CSI report, and SPS HARQ-ACK are configured in their respective corresponding configurations (first configuration or second configuration), for example, in their respective corresponding PUCCH configurations (PUCCH-Config).

[0282] In some embodiments, the network device generates a first DCI after determining the target uplink channel resources used by the terminal device.

[0283] In some embodiments, the network device sends a first DCI, where the first DCI is used to indicate the first configuration or the second configuration, and to indicate a target uplink channel resource used by the terminal device.

[0284] In some embodiments, the manner in which the first DCI indicates the first configuration or the second configuration includes explicit indication and implicit indication.

[0285] Explicit instructions:

[0286] In some embodiments, the first DCI includes a first indication field, where the first indication field is used to indicate the first configuration or the second configuration.

[0287] In some embodiments, based on a DCI format known before the filing date, the first indication field is a newly added indication field, or part of the bits of a known indication field.

[0288] In some embodiments, the first indication field is an indication field added outside the uplink channel resource indication field, or the first indication field is part of the bits of the uplink channel resource indication field.

[0289] When the first indication field is a newly added indication field outside the uplink channel resource indication field, it can indicate the first configuration or the second configuration more flexibly; when the first indication field is a partial bit of the uplink channel resource indication field, such as the highest bit or the lowest bit of the PRI indication field, no additional DCI overhead is added.

[0290] In some embodiments, the first indication field is part of the bits of the uplink channel resource indication field, including: the first indication field is the highest bit or the lowest bit of the PRI indication field.

[0291] The highest bit or the lowest bit of the PRI indication field is used to indicate the first configuration or the second configuration, and the remaining bits in the PRI indication field are used to indicate the PUCCH resource in the first configuration or the second configuration. Figure 14 shows a schematic diagram of the PRI indication field provided by an exemplary embodiment of the present application. When the PRI indication field takes the value 011, the highest bit takes the value 0 to indicate the first configuration, and the remaining bits take the value 11 to indicate the fourth PUCCH resource in the first configuration.

[0292] In some embodiments, when the time domain resources include a sub-time domain resource type, the sub-time domain resource type is used to indicate the first configuration or the second configuration; when the time domain resources include at least two sub-time domain resource types, the first DCI includes a first indication field, and the first indication field is used to indicate the first configuration or the second configuration.

[0293] Exemplarily, when a time slot includes only one symbol type, the first configuration or the second configuration is determined by the symbol type, and all bits of the first indicator field (PRI indicator field) are used to indicate the PUCCH resource. When a time slot includes at least two symbol types, some bits in the first indicator field are used to indicate the first configuration or the second configuration, and the remaining bits are used to indicate the target PUCCH resource. As shown in Figure 7, when a time slot includes only SBFD symbols, the first configuration is determined by the symbol type. When a time slot includes only non-SBFD symbols, the second configuration is determined by the symbol type. When a time slot includes both SBFD and non-SBFD symbols, the highest bit in the first indicator field is used to indicate the first configuration or the second configuration, and the remaining bits are used to indicate the target PUCCH resource.

[0294] Implicit instructions:

[0295] In some embodiments, the DCI format of the first DCI is used to indicate the first configuration or the second configuration; or, the DCI format of the first DCI is associated with the first configuration or the second configuration; or, the Radio Network Temporary Identifier sequence (RNTI) used to scramble the first DCI is used to indicate the first configuration or the second configuration; or, the RNTI used to scramble the first DCI is associated with the first configuration or the second configuration; or, the resource position or resource index of the downlink control resource carrying the first DCI is used to indicate the first configuration or the second configuration; or, the resource position or resource index of the downlink control resource carrying the first DCI is associated with the first configuration or the second configuration.

[0296] Exemplarily, when the DCI format of the first DCI is format A, it is used to indicate the first configuration; when the DCI format of the first DCI is format B, it is used to indicate the second configuration. When the RNTI is the first RNTI, it is used to indicate the first configuration; when the RNTI is the second RNTI, it is used to indicate the second configuration.

[0297] For example, when the resource index is a control channel element (CCE) index, when the CCE index number is 1, it indicates the first configuration; when the CCE index number is 2, it indicates the second configuration. In one embodiment, the CCE index number may refer to the lowest CCE index number where the PDCCH is located, or the highest CCE index number where the PDCCH is located.

[0298] Indicating the first configuration or the second configuration in different ways can meet the needs of different scenarios without requiring additional DCI overhead.

[0299] In some embodiments, the network device sends high-layer signaling to the terminal device, where the high-layer signaling is used to indicate the first configuration or the second configuration.

[0300] In some embodiments, a first configuration or a second configuration is used in a time slot including at least two types of time domain resources, configured via higher-layer signaling. The higher layers refer to protocol layers above the physical layer, such as the System Information Block (SIB), Radio Resource Control (RRC), and Media Access Control (MAC).

[0301] Configuring high-layer signaling by network devices can support a variety of configuration methods based on actual needs without requiring additional DCI overhead. For example, using the PUCCH resource as an uplink channel resource, the advantage of using the first configuration is that it ensures that the PUCCH resource falls within the valid uplink resource (UL resource). The advantage of using the second configuration is that it avoids uplink resource fragmentation and reduces link interference.

[0302] For example, if a time slot within a period includes only SBFD symbols, the network device instructs the terminal device to use the first configuration via high-layer signaling. For another example, if a time slot within another period includes only non-SBFD symbols, the network device instructs the terminal device to use the second configuration via high-layer signaling. For another example, if the high-layer signaling carries the window parameters of at least one time window and the correspondence between each time window and the first or second configuration, the terminal device determines the first or second configuration to use for the current time window based on the correspondence. The window parameters of a time window include at least one of: a starting position, an ending position, a length, a period start point, and a period length.

[0303] Figure 15 shows a schematic diagram of a high-level signaling indication provided by an exemplary embodiment of the present application. The high-level signaling carries window parameters of the first time window and the second time window, and the first time window corresponds to the first configuration and the second time window corresponds to the second configuration. The starting position of the first time window is the starting position of the first symbol, and the length is 8 symbols; the starting position of the second time window is the starting position of the 9th symbol, and the length is 6 symbols. Taking the example of SBFD symbols occupying 8 symbols and non-SBFD symbols occupying 6 symbols, the first configuration is used in the SBFD symbol to determine the target PUCCH resource (one of the first 4 shaded blocks in the figure); the second configuration is used in the non-SBFD symbol to determine the target PUCCH resource (one of the last 3 shaded blocks in the figure).

[0304] In some embodiments, the first configuration or the second configuration is used for the target uplink channel resource determined to be used by the terminal device; the target uplink channel resource is the uplink channel resource used when at least two UCIs of the terminal device are multiplexed, and at least two uplink channel resources corresponding to at least two UCIs before multiplexing are in the same time unit, or at least two uplink channel resources overlap.

[0305] In some embodiments, a target uplink channel resource used by the terminal device is determined, wherein the target uplink channel resource is an uplink channel resource used when at least two UCIs of the terminal device are multiplexed.

[0306] In some embodiments, after determining the target uplink channel resource used by the terminal device, at least two multiplexed UCIs are received on the target uplink channel resource.

[0307] In some embodiments, the target uplink channel resource is the uplink channel resource used when at least two UCIs of the terminal device are multiplexed, and at least two uplink channel resources corresponding to at least two UCIs before multiplexing are in the same time unit, or at least two uplink channel resources overlap.

[0308] Taking the uplink channel resource as an example, which is a PUCCH resource, the terminal device will transmit at least two PUCCH resources (carrying at least two UCIs) in the first time slot, and at least two PUCCH resources overlap (partially overlap or fully overlap), or at least two PUCCH resources are in the same time unit (time slot, sub-time slot, symbol group, etc.), where the first time slot is a mixed symbol time slot type, i.e., including SBFD symbols and non-SBFD symbols, then the terminal device multiplexes at least two UCIs in the target PUCCH resource for transmission.

[0309] In some embodiments, when the at least two uplink channel resources include a dynamically scheduled first uplink channel resource, the network device determines, for the terminal device, at least two target uplink channel resources for UCI multiplexing based on a multiplexing resource determination method of related technologies. The method further includes:

[0310] A second DCI is sent, where the second DCI is used to indicate the first configuration or the second configuration corresponding to the target uplink channel resource, and is used to indicate the first uplink channel resource.

[0311] Case 1: The time domain resource type corresponding to the first uplink channel resource indicated by the second DCI is the same as the time domain resource type corresponding to the target uplink channel resource. That is, when the target uplink channel resource corresponds to an SBFD symbol, the first uplink channel resource also corresponds to an SBFD symbol; when the target uplink channel resource corresponds to a non-SBFD symbol, the first uplink channel resource also corresponds to a non-SBFD symbol.

[0312] Case 2: The configuration corresponding to the first uplink channel resource indicated by the second DCI is the same as the configuration corresponding to the target uplink channel resource. That is, when the target uplink channel resource corresponds to the first configuration, the first uplink channel resource also corresponds to the first configuration; when the target uplink channel resource corresponds to the second configuration, the first uplink channel resource also corresponds to the second configuration.

[0313] Case three: The second indication field in the second DCI is used to indicate the first configuration or the second configuration; or, the DCI format in the second DCI is used to indicate the first configuration or the second configuration; or, the RNTI used to scramble the second DCI is used to indicate the first configuration or the second configuration; or, the resource location or resource index carrying the second DCI is used to indicate the first configuration or the second configuration.

[0314] Exemplarily, the second indication field indicates the first configuration or the second configuration through one bit. For example, when the bit value is 0, it indicates the first configuration, and when the bit value is 1, it indicates the second configuration. When the DCI format of the second DCI is format A, it is used to indicate the first configuration; when the DCI format of the second DCI is format B, it is used to indicate the second configuration. When the RNTI is the first RNTI, it is used to indicate the first configuration; when the RNTI is the second RNTI, it is used to indicate the second configuration. In the case where the resource index is a CCE index, when the CCE index number is 1, it is used to indicate the first configuration; when the CCE index number is 2, it is used to indicate the second configuration.

[0315] Through the above different indication methods, the first configuration or the second configuration can be accurately indicated in different situations.

[0316] In some embodiments, when at least two first uplink channel resources are dynamically scheduled by at least two second DCIs, the network device sends a last DCI, and the last DCI is used to indicate the first configuration or the second configuration corresponding to the target uplink channel resource; wherein the last DCI is the last of the at least two second DCIs.

[0317] In some embodiments, the method further includes: determining a target uplink channel resource used by the terminal device among the uplink channel resources configured by the first configuration or the second configuration.

[0318] In some embodiments, when a first configuration is used based on a communication protocol agreement, a target uplink channel resource used by a terminal device is determined among the uplink channel resources configured by the first configuration; when a second configuration is used based on a communication protocol agreement, a target uplink channel resource used by a terminal device is determined among the uplink channel resources configured by the second configuration.

[0319] The communication protocol stipulates that no network equipment configuration is required, and there is no additional DCI overhead. For example, using the PUCCH resource as the uplink channel resource, the advantage of using the first configuration is that it ensures that the PUCCH resource falls within the valid uplink resource (valid UL resource). The advantage of using the second configuration is that it avoids uplink resource fragmentation and reduces link interference.

[0320] For example, if a time slot within a certain period includes only SBFD symbols, the communication protocol stipulates the use of the first configuration. Another example is that a time slot within another period includes only non-SBFD symbols, and the communication protocol stipulates the use of the second configuration. In another example, if the communication protocol stipulates window parameters for at least one time window and a correspondence between each time window and the first or second configuration, the terminal device determines whether to use the first or second configuration for the current time window based on this correspondence. The window parameters of a time window include at least one of: a starting position, an ending position, a length, a period start point, and a period length.

[0321] In some embodiments, when at least two uplink channel resources correspond to the first configuration, the target uplink channel resources used by the terminal device are determined among the uplink channel resources configured by the first configuration; when at least two uplink channel resources correspond to the second configuration, the target uplink channel resources used by the terminal device are determined among the uplink channel resources configured by the second configuration.

[0322] Taking the uplink channel resource as the PUCCH resource as an example, Figure 19 shows a schematic diagram of determining the PUCCH resource provided by an exemplary embodiment of the present application. The at least two PUCCH resources include PUCCH 1 and PUCCH 2. When PUCCH 1 and PUCCH 2 both correspond to the first configuration, the target PUCCH resource used by the terminal device is determined among the PUCCH resources configured by the first configuration.

[0323] If the at least two PUCCH resources both correspond to the first configuration, the target PUCCH resource corresponds to the first configuration; if the at least two PUCCH resources both correspond to the second configuration, the target PUCCH resource corresponds to the second configuration.

[0324] In some embodiments, when at least two uplink channel resources correspond to a first configuration and a second configuration, the target uplink channel resources used by the terminal device are determined among the uplink channel resources configured by the first configuration; or, when at least two uplink channel resources correspond to a first configuration and a second configuration, the target uplink channel resources used by the terminal device are determined among the uplink channel resources configured by the second configuration.

[0325] Taking the uplink channel resource as the PUCCH resource as an example, Figure 20 shows a schematic diagram of determining the PUCCH resource provided by an exemplary embodiment of the present application. The at least two PUCCH resources include PUCCH 1 and PUCCH 2. When PUCCH 1 and PUCCH 2 correspond to the first configuration and the second configuration, the target PUCCH resource used by the terminal device is determined in the PUCCH resources configured by the first configuration.

[0326] If at least two PUCCH resources correspond to the first configuration and the second configuration, and the target PUCCH resource corresponds to the first configuration, taking the first configuration corresponding to the SBFD symbol as an example, the middle subband of the SBFD symbol can be configured as an uplink subband to ensure that the target PUCCH resource is within the valid uplink resource (valid UL resource); or, if at least two PUCCH resources correspond to the first configuration and the second configuration, and the target PUCCH resource corresponds to the second configuration, taking the second configuration corresponding to the non-SBFD symbol as an example, uplink resource fragmentation can be avoided while reducing link interference.

[0327] In some embodiments, a UE is provided first and second for each of {PUCCH-ResourceSet,PUCCH-Resource except the startingSymbolIndex and nrofSymbols}, respectively for use with PUCCH (SR, CSI, HARQ-ACK) occupying the first symbol type and the second symbol type respectively, where the first symbol type is SBFD symbol and the second symbol type is non-SBFD symbol.

[0328] In some embodiments, a first and a second configuration for each of {PUCCH-ResourceSet,PUCCH-Resource},respectively for use with PUCCH(SR,CSI,HARQ-ACK)occupying the first symbol type and the second symbol type respectively,where,the first symbol type and the second symbol type are SBFD symbol type and non-SBFD symbol type.UE expects that the corresponding PUCCH resource in the first config and the second config to occupy the same symbols.

[0329] In some embodiments, the terminal device is configured with a second configuration parameter and an offset value, the second configuration parameter corresponds to the second configuration, the offset value is a resource block (RB) offset (RB offset), and the RB offset is used to adjust the frequency domain resources of the PUCCH resources. Taking the first configuration corresponding to the SBFD symbol and the second configuration corresponding to the non-SBFD symbol as an example, the RB offset is the frequency domain offset of the PUCCH resource located in the SBFD symbol relative to the PUCCH resource located in the non-SBFD symbol.

[0330] In some embodiments, the terminal device is configured with a first configuration parameter and an offset value, the first configuration parameter corresponds to a first configuration, and the offset value is an RB offset. Taking the first configuration corresponding to SBFD symbols and the second configuration corresponding to non-SBFD symbols as an example, the RB offset is the frequency domain offset of the PUCCH resources located in the non-SBFD symbols relative to the PUCCH resources located in the SBFD symbols.

[0331] Figure 16 shows a schematic diagram of the PUCCH resource offset provided by an exemplary embodiment of the present application. Taking the case where the terminal device is configured with the second configuration parameter (PUCCH configuration 3) and the offset value, the offset value is an RB offset, the first configuration corresponds to the SBFD symbol, and the second configuration corresponds to the non-SBFD symbol as an example, the frequency domain resource parameters in PUCCH configuration 3 are added with the offset value and together with other resource parameters form PUCCH configuration 4.

[0332] Figure 17 shows a schematic diagram of a PUCCH resource offset provided by an exemplary embodiment of the present application. In some embodiments, the starting position of the PUCCH resource corresponding to the non-SBFD symbol is the configured starting RB, and the starting position of the PUCCH resource corresponding to the SBFD symbol is (startingPRB+RB_offset)mod(UL_subband size∩active UL BWP size), where startingPRB is the starting physical resource block, RB_offset is the RB offset, UL_subband size is the uplink subband size, active UL BWP size is the size of the activated uplink bandwidth portion, ∩ is the intersection operation, and mod is the remainder operation. The RBs occupied by the PUCCH resource located in the SBFD symbol are 1 RB starting from the starting position, or n RBs, where n is the number of PRBs parameter (nrofPRBs).

[0333] In some embodiments, the RB offset may be one RB offset, or a list of RB offsets, where each RB offset corresponds to one PUCCH resource or one PUCCH resource set.

[0334] In some embodiments, a set of configuration parameters (PUCCH-Config) is configured for the terminal device, and each PUCCH resource set in the set of configuration parameters includes N PUCCH resources, where N is twice the maximum number of PUCCH resources that can be configured in the current PUCCH resource set, wherein the first N / 2 PUCCH resources correspond to non-SBFD symbols, and the last N / 2 PUCCH resources correspond to SBFD symbols, or the first N / 2 PUCCH resources correspond to SBFD symbols, and the last N / 2 PUCCH resources correspond to non-SBFD symbols, and the first N / 2 PUCCH resources and the last N / 2 PUCCH resources share or do not share the time domain configuration.

[0335] In some embodiments, a set of configuration parameters (PUCCH-Config) is configured for the terminal device, and the set of configuration parameters includes M PUCCH resource sets, wherein the first M / 2 PUCCH resource sets correspond to non-SBFD symbols, and the second M / 2 PUCCH resource sets correspond to SBFD symbols, or the first M / 2 PUCCH resource sets correspond to SBFD symbols, and the second M / 2 PUCCH resource sets correspond to non-SBFD symbols, and the first M / 2 PUCCH resource sets and the second M / 2 PUCCH resource sets share or do not share the time domain configuration.

[0336] Figure 18 shows a schematic diagram of configuring PUCCH resources according to an exemplary embodiment of the present application. In a time slot, the first seven symbols are SBFD symbols, and the eighth to fourteenth symbols are non-SBFD symbols. In some embodiments, the first seven PUCCH resources in the PUCCH resource set are located at a first frequency domain location; the last seven PUCCH resources in the PUCCH resource set are located at a second frequency domain location.

[0337] In some embodiments, the information configured separately in the above method also includes at least one of the following in addition to PUCCH resources: PUCCH power control configuration parameters (PUCCH-PowerControl), PUCCH spatial configuration parameters (PUCCH-SpatialRelationInfo), SR configuration parameters (SchedulingRequestResourceConfig), etc.; the shared configuration information in the above method also includes the time domain offset configuration (dl-DataToUL-ACK) from PDSCH to HARQ-ACK.

[0338] In some embodiments, after determining the target uplink channel resource used by the terminal device, UCI sent by the terminal device, such as a HARQ-ACK codebook, is received on the target uplink channel resource.

[0339] In some embodiments, the terminal device does not expect that the configurations corresponding to at least two uplink channel resources are different; or, the terminal device expects that the configurations corresponding to at least two uplink channel resources are the same; or, the terminal device expects that at least two uplink channel resources both correspond to the first configuration; or, the terminal device expects that at least two uplink channel resources both correspond to the second configuration.

[0340] In some embodiments, the terminal device does not expect the target uplink channel resource to be configured or indicated by the network device, and the target uplink channel resource is in a time slot including both the first type of time domain resources and the second type of time domain resources.

[0341] The network device will try to configure itself in accordance with the expectations of the terminal device, but it may not always do so. In some cases, the network device may send configuration information in a manner that the terminal device does not expect. In this case, this application does not limit how the terminal device handles the unexpected configuration information; for example, the terminal device may independently implement it.

[0342] In some embodiments, the configurations corresponding to the at least two uplink channel resources include a first configuration and / or a second configuration.

[0343] In some embodiments, when the configurations corresponding to at least two uplink channel resources are different, the UCI corresponding to at least two uplink channel resources are not multiplexed. At this time, the terminal device will construct two HARQ-ACK codebooks, HARQ-ACK codebook 1 corresponds to the first configuration, and HARQ-ACK codebook 2 corresponds to the second configuration.

[0344] To sum up, the method provided in this embodiment sends a first configuration and a second configuration; wherein, the first configuration and the second configuration are used to configure relevant parameters of the uplink channel resources, the first configuration corresponds to the first type of time domain resources, and the second configuration corresponds to the second type of time domain resources, so that the terminal device can use different configurations to determine the uplink channel resources to be used for different types of time domain resources.

[0345] FIG26 shows a flowchart of a method for sending resource configuration provided by an exemplary embodiment of the present application. The method is executed by a network device and includes:

[0346] Step 2610: Send the third configuration.

[0347] The third configuration is used to configure relevant parameters of uplink channel resources in a time unit having first-type time domain resources and second-type time domain resources.

[0348] For the specific implementation details of the sending configuration, please refer to the embodiment of Figure 25 and will not be repeated here.

[0349] In some embodiments, the uplink channel resources used by at least one of the SR, CSI report, and SPS HARQ-ACK signals corresponding to the third configuration are the uplink channel resources configured by the third configuration.

[0350] In some embodiments, the relevant parameters of SR, CSI report, and SPS HARQ-ACK are configured in their respective corresponding configurations (third configurations), for example, in their respective corresponding PUCCH configurations (PUCCH-Config).

[0351] In some embodiments, the method further includes: sending a first configuration and / or a second configuration; wherein the first configuration is used to configure relevant parameters of uplink channel resources in time units having (only) first type of time domain resources, and the second configuration is used to configure relevant parameters of uplink channel resources in time units having (only) second type of time domain resources.

[0352] In some embodiments, the uplink channel resources used by at least one of the SR, CSI report, and SPS HARQ-ACK signals corresponding to the first configuration are the uplink channel resources configured by the first configuration; the uplink channel resources used by at least one of the SR, CSI report, and SPS HARQ-ACK signals corresponding to the second configuration are the uplink channel resources configured by the second configuration.

[0353] In some embodiments, the relevant parameters of SR, CSI report, and SPS HARQ-ACK are configured in their respective corresponding configurations (first configuration or second configuration), for example, in their respective corresponding PUCCH configurations (PUCCH-Config).

[0354] In some embodiments, the method further includes: determining the target uplink channel resources used by the terminal device among the uplink channel resources configured by at least one of the first configuration, the second configuration, and the third configuration; wherein the first configuration corresponds to the first type of time domain resources, and the second configuration corresponds to the second type of time domain resources.

[0355] In some embodiments, taking the example that the first configuration, the second configuration and the third configuration correspond to the first time slot type, the second time slot type and the third time slot type respectively, the first time slot type is a time slot type that only includes SBFD symbols, the second time slot type is a time slot type that only includes non-SBFD symbols, and the third time slot type is a time slot type that includes both SBFD symbols and non-SBFD symbols.

[0356] To sum up, the method provided in this embodiment sends a third configuration; wherein, the third configuration is used to configure relevant parameters of the uplink channel resources of the time unit having the first type of time domain resources and the second type of time domain resources, so that the terminal device can use the third configuration to determine the uplink channel resources to be used for the mixed type of time domain resources.

[0357] In the above embodiments, the embodiment corresponding to FIG6 , the embodiment corresponding to FIG24 , the embodiment corresponding to FIG25 , and the embodiment corresponding to FIG26 may be implemented individually or in combination, and this application does not impose any limitation thereto.

[0358] FIG27 shows a block diagram of an apparatus for determining uplink channel resources provided by an exemplary embodiment of the present application. The apparatus can be implemented as a terminal device, or as a part of a terminal device, through software or hardware, or a combination of both. The apparatus includes:

[0359] The determination module 2710 is configured to determine a target uplink channel resource from the uplink channel resources configured in the first configuration or the second configuration.

[0360] The first configuration and the second configuration are used to configure relevant parameters of the uplink channel resources, the first configuration corresponds to the first type of time domain resources, and the second configuration corresponds to the second type of time domain resources.

[0361] In one possible design of this embodiment, the uplink channel resources include at least one of the following: PUCCH resources, physical uplink shared channel (PUSCH) resources, physical random access channel (PRACH) resources, etc. This embodiment of the present application is not limited to this, and the PUCCH resources are used as an example for illustration. The PUCCH resources in the embodiments of the present application are all illustrative examples and can be upgraded to uplink channel resources.

[0362] In one possible design of this embodiment, the time domain resources include at least one of the following: a symbol, a symbol group, a time slot, a sub-time slot, a frame, and a subframe. The specific type of time domain resources is not limited in the embodiments of the present application. Generally, the first configuration corresponds to a first type of symbol, and the second configuration corresponds to a second type of symbol. For example, the first configuration corresponds to an SBFD symbol, and the second configuration corresponds to a non-SBFD symbol. An SBFD symbol is a symbol that includes at least one of an uplink subband, a downlink subband, and a guard band, while a non-SBFD symbol is a symbol that does not include any of the above subbands.

[0363] In a possible design of this embodiment, the first configuration is applicable to time slots in which all symbols are SBFD symbols, and also to time slots in which some symbols are SBFD symbols; the second configuration is applicable to time slots in which all symbols are non-SBFD symbols, and also to time slots in which some symbols are non-SBFD symbols.

[0364] In a possible design of this embodiment, the first configuration and the second configuration share time domain resource parameters.

[0365] In a possible design of this embodiment, the first configuration and the second configuration do not share time domain resource parameters.

[0366] In one possible design of this embodiment, the target uplink channel resource is a resource used to send uplink control information (UCI). In one possible design of this embodiment, the target uplink channel resource is a resource used to feedback HARQ-ACK or a HARQ-ACK codebook. In one possible design of this embodiment, the target uplink channel resource is a resource used when multiplexing at least two UCIs.

[0367] In a possible design of this embodiment, the determination module 2710 is used to determine the target uplink channel resources through at least one of the following methods.

[0368] Method 1: Determine the configuration (first configuration or second configuration) corresponding to the target uplink channel resource according to the time domain resources occupied by the target uplink channel resource.

[0369] Taking the target uplink channel resource as a resource for feedback of HARQ-ACK or HARQ-ACK codebook as an example, the resource index and / or time domain resource of the target uplink channel resource is indicated by DCI, such as by the PRI field of DCI. After determining the time domain resource occupied by the target uplink channel resource based on the DCI, the first configuration or the second configuration is selected based on the time domain resource occupied by the target uplink channel resource to determine other configuration parameters of the target uplink channel resource other than the time domain resource parameters.

[0370] In a possible design of this embodiment, the determination module 2710 is used to determine the target uplink channel resource among the uplink channel resources configured by the first configuration when the time domain resources occupied by the target uplink channel resource are the first type of time domain resources; and to determine the target uplink channel resource among the uplink channel resources configured by the second configuration when the time domain resources occupied by the target uplink channel resource are the second type of time domain resources.

[0371] Determining the target uplink channel resource in the first configuration or the second configuration based on the time domain resources occupied by the target uplink channel resource is simple to implement, can reduce the amount of calculation and power consumption of the uplink channel resource determination device, and improve the efficiency of determining the target uplink channel resource.

[0372] In a possible design of this embodiment, the relevant parameters of the target uplink channel resource are determined according to the first configuration or the second configuration based on the time domain resources occupied by the target uplink channel resource.

[0373] Exemplarily, if the target PUCCH resource occupies an SBFD symbol, then all or part of the relevant parameters of the target PUCCH resource are determined according to the first configuration; if the target PUCCH resource occupies a non-SBFD symbol, then all or part of the relevant parameters of the target PUCCH resource are determined according to the second configuration.

[0374] In a possible design of this embodiment, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), orthogonal cover code (Orthogonal Cover Code, OCC) parameters, time domain resource parameters (e.g., starting symbol index startingSymbolIndex, number of symbols nrofSymbols).

[0375] In a possible design of this embodiment, in the first configuration and the second configuration, the time domain resource configuration corresponding to the associated uplink channel resource is the same. In this case, the relevant parameters determined for the target uplink channel resource according to the first configuration or the second configuration do not include the time domain resource parameter.

[0376] In one possible design of this embodiment, the uplink channel resource determination apparatus expects that the time domain resource configurations corresponding to the associated uplink channel resources in the first configuration and the second configuration are the same; and / or the uplink channel resource determination apparatus does not expect that the time domain resource configurations corresponding to the associated uplink channel resources in the first configuration and the second configuration are different. That is, the time domain resource parameters are carried in the first configuration and the second configuration and are exactly the same in both configurations.

[0377] In one possible design of this embodiment, the time domain resource configurations corresponding to the associated uplink channel resources do not need to be configured separately, so that the time domain resources are the same regardless of which configuration the uplink channel resource determination device uses to determine the uplink channel resources. In one possible design of this embodiment, the time domain resource parameters shared by the first and second configurations are additionally configured by the network device or agreed upon by the communication protocol. In this case, the time domain resource parameters are not included in the first and second configurations.

[0378] In a possible design of this embodiment, the associated uplink channel resources correspond to the same uplink channel resource identifier; or, the two uplink channel resource identifiers corresponding to the associated uplink channel resources have a pre-agreed corresponding relationship.

[0379] In one possible design of this embodiment, an uplink channel resource is a PUCCH resource as an example. A first PUCCH resource set is configured in a first configuration, and a second PUCCH resource set is configured in a second configuration. The first PUCCH resource set and the second PUCCH resource set are from different configurations, but there are associated PUCCH resources in the two PUCCH resource sets.

[0380] In a possible design of this embodiment, uplink channel resources corresponding to the same uplink channel resource identifier (IDentification, ID) are associated; or,

[0381] The uplink channel resources corresponding to two uplink channel resource IDs having a pre-agreed corresponding relationship are associated.

[0382] The associated uplink channel resources may correspond to the same uplink channel resource identifier, or may be two uplink channel resource IDs with a pre-agreed corresponding relationship, which can adapt to the association requirements of uplink channel resources in different situations.

[0383] In one possible design of this embodiment, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), and orthogonal cover code (OCC) parameters. The relevant parameters do not include time domain resource parameters, such as starting symbol index (startingSymbolIndex) and number of symbols (nrofSymbols). The time domain resource parameters are configured through other configurations, not through the first configuration or the second configuration.

[0384] When the relevant parameters do not include time domain resource parameters, they will be configured through other configurations, which is more flexible.

[0385] In a possible design of this embodiment, the PUCCH resources used by at least one of the signals including the Scheduling Request (SR), Channel State Information (CSI) report, and Semi-Persistent Scheduling Hybrid Automatic Repeat reQuest ACKnowledgment (SPS HARQ-ACK) corresponding to the first configuration are the PUCCH resources configured by the first configuration; the PUCCH resources used by at least one of the signals including the SR, CSI report, and SPS HARQ-ACK corresponding to the second configuration are the PUCCH resources configured by the second configuration.

[0386] In a possible design of this embodiment, relevant parameters of SR, CSI report, and SPS HARQ-ACK are configured in their respective corresponding configurations (first configuration or second configuration), for example, in their respective corresponding PUCCH configurations (PUCCH-Config).

[0387] Method 2: Determine the target uplink channel resource according to the instruction of the first DCI.

[0388] In one possible design of this embodiment, determination module 2710 is configured to, when a first DCI indicates a first configuration, determine a target uplink channel resource from among the uplink channel resources configured by the first configuration; and, when the first DCI indicates a second configuration, determine the target uplink channel resource from among the uplink channel resources configured by the second configuration; wherein the first DCI is configured to indicate the target uplink channel resource. For example, the first DCI is further configured to indicate a PRI corresponding to the target PUCCH resource.

[0389] Determining the target uplink channel resource according to the indication of the first DCI can improve the flexibility and accuracy of the target uplink channel resource indication.

[0390] In a possible design of this embodiment, the first configuration or second configuration related parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), OCC parameters, time domain resource parameters (e.g., starting symbol index startingSymbolIndex, number of symbols nrofSymbols).

[0391] The first configuration or the second configuration may also be a PUCCH configuration (PUCCH-Config), a PUCCH resource set (PUCCH-ResourceSet), or a PUCCH resource (PUCCH-resource).

[0392] In some embodiments, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), and OCC parameters. The relevant parameters do not include time domain resource parameters, such as starting symbol index (startingSymbolIndex) and number of symbols (nrofSymbols). The time domain resource parameters are configured through other configurations, not through the first configuration or the second configuration.

[0393] In a possible design of this embodiment, the manner in which the first DCI indicates the first configuration or the second configuration includes explicit indication and implicit indication.

[0394] Explicit instructions:

[0395] In a possible design of this embodiment, the first DCI includes a first indication field, and the first indication field is used to indicate the first configuration or the second configuration.

[0396] In some embodiments, based on a DCI format known before the filing date, the first indication field is a newly added indication field, or part of the bits of a known indication field.

[0397] In a possible design of this embodiment, the first indication field is an indication field added outside the uplink channel resource indication field, or the first indication field is part of the bits of the uplink channel resource indication field.

[0398] When the first indication field is a newly added indication field outside the uplink channel resource indication field, it can indicate the first configuration or the second configuration more flexibly; when the first indication field is a partial bit of the uplink channel resource indication field, such as the highest bit or the lowest bit of the PRI indication field, no additional DCI overhead is added.

[0399] In a possible design of this embodiment, the first indication field is part of the bits of the uplink channel resource indication field, including: the first indication field is the highest bit or the lowest bit of the PRI indication field.

[0400] The highest bit or the lowest bit of the PRI indication field is used to indicate the first configuration or the second configuration, and the remaining bits in the PRI indication field are used to indicate the PUCCH resources in the first configuration or the second configuration.

[0401] In a possible design of this embodiment, when the time domain resources include a sub-time domain resource type, the sub-time domain resource type is used to indicate the first configuration or the second configuration; when the time domain resources include at least two sub-time domain resource types, the first DCI includes a first indication field, and the first indication field is used to indicate the first configuration or the second configuration.

[0402] Exemplarily, when a time slot includes only one symbol type, the first configuration or the second configuration is determined by the symbol type, and all bits of the first indicator field (PRI indicator field) are used to indicate the PUCCH resource. When a time slot includes at least two symbol types, some bits in the first indicator field are used to indicate the first configuration or the second configuration, and the remaining bits are used to indicate the target PUCCH resource. As shown in Figure 7, when a time slot includes only SBFD symbols, the first configuration is determined by the symbol type. When a time slot includes only non-SBFD symbols, the second configuration is determined by the symbol type. When a time slot includes both SBFD and non-SBFD symbols, the highest bit in the first indicator field is used to indicate the first configuration or the second configuration, and the remaining bits are used to indicate the target PUCCH resource.

[0403] Implicit instructions:

[0404] In a possible design of this embodiment, the DCI format of the first DCI is used to indicate the first configuration or the second configuration; or, the DCI format of the first DCI is associated with the first configuration or the second configuration; or, the Radio Network Temporary Identifier sequence (RNTI) used to scramble the first DCI is used to indicate the first configuration or the second configuration; or, the RNTI used to scramble the first DCI is associated with the first configuration or the second configuration; or, the resource position or resource index of the downlink control resource carrying the first DCI is used to indicate the first configuration or the second configuration; or, the resource position or resource index of the downlink control resource carrying the first DCI is associated with the first configuration or the second configuration.

[0405] Exemplarily, when the DCI format of the first DCI is format A, it is used to indicate the first configuration; when the DCI format of the first DCI is format B, it is used to indicate the second configuration. When the RNTI is the first RNTI, it is used to indicate the first configuration; when the RNTI is the second RNTI, it is used to indicate the second configuration.

[0406] For example, when the resource index is a control channel element (CCE) index, when the CCE index number is 1, it indicates the first configuration; when the CCE index number is 2, it indicates the second configuration. In one embodiment, the CCE index number may refer to the lowest CCE index number where the PDCCH is located, or the highest CCE index number where the PDCCH is located.

[0407] Indicating the first configuration or the second configuration in different ways can meet the needs of different scenarios without requiring additional DCI overhead.

[0408] Method 3: Determine the target uplink channel resources according to the instructions of the higher-layer signaling.

[0409] In a possible design of this embodiment, the determination module 2710 is used to determine the target uplink channel resources among the uplink channel resources configured by the first configuration when the high-level signaling indicates the first configuration; and to determine the target uplink channel resources among the uplink channel resources configured by the second configuration when the high-level signaling indicates the second configuration.

[0410] In one possible design of this embodiment, high-layer signaling is used to configure, in a time unit including at least two types of time domain resources, the use of the first configuration or the second configuration. The time unit including at least two types of time domain resources may be a time slot including at least two types of symbols, referred to as a mixed-type time slot.

[0411] The upper layer refers to the protocol layer above the physical layer, such as the System Information Block (SIB), Radio Resource Control (RRC), and Media Access Control (MAC).

[0412] In a possible design of this embodiment, the first configuration or second configuration related parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), OCC parameters, time domain resource parameters (e.g., starting symbol index startingSymbolIndex, number of symbols nrofSymbols).

[0413] The first configuration or the second configuration may also be a PUCCH configuration (PUCCH-Config), a PUCCH resource set (PUCCH-ResourceSet), or a PUCCH resource (PUCCH-resource).

[0414] In some embodiments, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), and OCC parameters. The relevant parameters do not include time domain resource parameters, such as starting symbol index (startingSymbolIndex) and number of symbols (nrofSymbols). The time domain resource parameters are configured through other configurations, not through the first configuration or the second configuration.

[0415] Configuring high-level signaling by network devices can support a variety of configuration methods, be configured according to actual needs, and do not require additional DCI overhead. Taking the uplink channel resource as an example, the benefit of agreeing to use the first configuration is to ensure that the PUCCH resource falls within the valid uplink resource (valid UL resource), and the benefit of agreeing to use the second configuration is to avoid uplink resource fragmentation and reduce link interference. For example, during a period of time, the time slots only include SBFD symbols, and the network device instructs the uplink channel resource determination device to use the first configuration through high-level signaling; for another example, during another period of time, the time slots only include non-SBFD symbols, and the network device instructs the uplink channel resource determination device to use the second configuration through high-level signaling. For another example, the high-level signaling carries the window parameters of at least one time window and the correspondence between each time window and the first configuration or the second configuration. The uplink channel resource determination device determines the first configuration or the second configuration to use for the current time window based on the above correspondence. The window parameters of the time window include at least one of: starting position, ending position, length, cycle start point, and cycle length.

[0416] Method 4: Determine the target uplink channel resources according to the communication protocol.

[0417] In a possible design of this embodiment, the determination module 2710 is used to determine the target uplink channel resources among the uplink channel resources configured by the first configuration when the first configuration is used based on the communication protocol agreement; and to determine the target uplink channel resources among the uplink channel resources configured by the second configuration when the second configuration is used based on the communication protocol agreement.

[0418] In one possible design of this embodiment, according to the communication protocol, the first configuration or the second configuration is used in a time unit including at least two types of time domain resources. The time unit including at least two types of time domain resources can be a time slot including at least two types of symbols, referred to as a mixed-type time slot.

[0419] In a possible design of this embodiment, the first configuration or second configuration related parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), OCC parameters, time domain resource parameters (e.g., starting symbol index startingSymbolIndex, number of symbols nrofSymbols).

[0420] The first configuration or the second configuration may also be a PUCCH configuration (PUCCH-Config), a PUCCH resource set (PUCCH-ResourceSet), or a PUCCH resource (PUCCH-resource).

[0421] In some embodiments, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), and OCC parameters. The relevant parameters do not include time domain resource parameters, such as starting symbol index (startingSymbolIndex) and number of symbols (nrofSymbols). The time domain resource parameters are configured through other configurations, not through the first configuration or the second configuration.

[0422] The communication protocol stipulates that no network equipment configuration is required, and there is no additional DCI overhead. For example, using the PUCCH resource as the uplink channel resource, the advantage of using the first configuration is that it ensures that the PUCCH resource falls within the valid uplink resource (valid UL resource). The advantage of using the second configuration is that it avoids uplink resource fragmentation and reduces link interference.

[0423] For example, if a time slot within a certain period includes only SBFD symbols, the communication protocol stipulates the use of the first configuration. Another example is that a time slot within another period includes only non-SBFD symbols, and the communication protocol stipulates the use of the second configuration. In another example, if the communication protocol stipulates the window parameters of at least one time window and the correspondence between each time window and the first configuration or the second configuration, the uplink channel resource determination device determines the first configuration or the second configuration to use for the current time window based on the correspondence. The window parameters of a time window include at least one of: a starting position, an ending position, a length, a cycle start point, and a cycle length.

[0424] In one possible design of this embodiment, a UE is provided first and second for each of {PUCCH-ResourceSet,PUCCH-Resource except the startingSymbolIndex and nrofSymbols}, respectively for use with PUCCH (SR, CSI, HARQ-ACK) occupying the first symbol type and the second symbol type respectively, where the first symbol type and the second symbol type are SBFD symbol type and non-SBFD symbol type.

[0425] In one possible design of this embodiment, a first configuration and a second configuration are provided for each of {PUCCH-ResourceSet,PUCCH-Resource}, respectively for use with PUCCH (SR, CSI, HARQ-ACK) occupying the first symbol type and the second symbol type respectively, where the first symbol type is SBFD symbol type and the second symbol type is non-SBFD symbol type.UE expects that the corresponding PUCCH resource in the first config and the second config to occupy the same symbols.

[0426] In a possible design of this embodiment, the device for determining uplink channel resources is configured with a second configuration parameter and an offset value, where the second configuration parameter corresponds to a second configuration, and the offset value is a resource block (RB) offset (RB offset). The RB offset is used to adjust the frequency domain resources of the PUCCH resources. Taking the first configuration corresponding to SBFD symbols and the second configuration corresponding to non-SBFD symbols as an example, the RB offset is the frequency domain offset of the PUCCH resources located in the SBFD symbols relative to the PUCCH resources located in the non-SBFD symbols.

[0427] In a possible design of this embodiment, the device for determining uplink channel resources is configured with a first configuration parameter and an offset value, where the first configuration parameter corresponds to a first configuration, and the offset value is an RB offset. Taking the first configuration corresponding to SBFD symbols and the second configuration corresponding to non-SBFD symbols as an example, the RB offset is the frequency domain offset of the PUCCH resources located in the non-SBFD symbols relative to the PUCCH resources located in the SBFD symbols.

[0428] Figure 16 shows a schematic diagram of a PUCCH resource offset provided by an exemplary embodiment of the present application. Taking the uplink channel resource determination device as an example, which is configured with a second configuration parameter (PUCCH configuration 3) and an offset value, where the offset value is an RB offset, the first configuration corresponds to an SBFD symbol, and the second configuration corresponds to a non-SBFD symbol, the frequency domain resource parameters in PUCCH configuration 3 are added with the offset value and together with other resource parameters form PUCCH configuration 4.

[0429] Figure 17 shows a schematic diagram of a PUCCH resource offset provided by an exemplary embodiment of the present application. In a possible design of this embodiment, the starting position of the PUCCH resource corresponding to the non-SBFD symbol is the configured starting RB, and the starting position of the PUCCH resource corresponding to the SBFD symbol is (startingPRB+RB_offset)mod(UL_subband size∩active UL BWP size), where startingPRB is the starting physical resource block, RB_offset is the RB offset, UL_subband size is the uplink subband size, active UL BWP size is the size of the activated uplink bandwidth part, ∩ is the intersection operation, and mod is the remainder operation. The RB occupied by the PUCCH resource located in the SBFD symbol is 1 RB starting from the starting position, or n RBs, where n is the PRB number parameter (nrofPRBs).

[0430] In a possible design of this embodiment, the RB offset may be one RB offset or a list of RB offsets, where each RB offset corresponds to one PUCCH resource or one PUCCH resource set.

[0431] In a possible design of this embodiment, the uplink channel resource determination device receives a set of configuration parameters (PUCCH-Config), where each PUCCH resource set includes N PUCCH resources, where N is twice the maximum number of PUCCH resources that can be configured in the current PUCCH resource set, wherein the first N / 2 PUCCH resources correspond to non-SBFD symbols, and the last N / 2 PUCCH resources correspond to SBFD symbols, or the first N / 2 PUCCH resources correspond to SBFD symbols, and the last N / 2 PUCCH resources correspond to non-SBFD symbols, and the first N / 2 PUCCH resources and the last N / 2 PUCCH resources share or do not share the time domain configuration.

[0432] In a possible design of this embodiment, the uplink channel resource determination device receives a set of configuration parameters (PUCCH-Config), which includes M PUCCH resource sets, where the first M / 2 PUCCH resource sets correspond to non-SBFD symbols and the last M / 2 PUCCH resource sets correspond to SBFD symbols, or the first M / 2 PUCCH resource sets correspond to SBFD symbols and the last M / 2 PUCCH resource sets correspond to non-SBFD symbols, and the first M / 2 PUCCH resource sets and the last M / 2 PUCCH resource sets share or do not share the time domain configuration.

[0433] In a possible design of this embodiment, the information configured separately in the above method also includes at least one of the following in addition to PUCCH resources: PUCCH power control configuration parameters (PUCCH-PowerControl), PUCCH spatial configuration parameters (PUCCH-SpatialRelationInfo), SR configuration parameters (SchedulingRequestResourceConfig), etc.; the information shared by the above method also includes the time domain offset configuration (dl-DataToUL-ACK) from PDSCH to HARQ-ACK.

[0434] Method 5: Determine a target uplink channel resource, where the target uplink channel resource is an uplink channel resource used when at least two UCIs are multiplexed.

[0435] In a possible design of this embodiment, the target uplink channel resource is the uplink channel resource used when at least two UCIs are multiplexed, and the at least two uplink channel resources corresponding to the at least two UCIs before multiplexing are in the same time unit, or the at least two uplink channel resources overlap.

[0436] The uplink channel resource determination device is about to transmit at least two uplink channel resources (carrying at least two UCIs) in the first time slot, and the at least two uplink channel resources overlap (partially overlap or fully overlap), or the at least two uplink channel resources are in the same time unit (time slot, sub-time slot, symbol group, etc.), wherein the first time slot is a mixed symbol time slot type, that is, including SBFD symbols and non-SBFD symbols, then the uplink channel resource determination device multiplexes the at least two UCIs in the target uplink channel resource for transmission.

[0437] In a possible design of this embodiment, the first configuration or second configuration related parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), OCC parameters, time domain resource parameters (e.g., starting symbol index startingSymbolIndex, number of symbols nrofSymbols).

[0438] The first configuration or the second configuration may also be a PUCCH configuration (PUCCH-Config), a PUCCH resource set (PUCCH-ResourceSet), or a PUCCH resource (PUCCH-resource).

[0439] In some embodiments, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), and OCC parameters. The relevant parameters do not include time domain resource parameters, such as starting symbol index (startingSymbolIndex) and number of symbols (nrofSymbols). Time domain resource parameters are configured through other configurations, not through the first configuration or the second configuration.

[0440] In a possible design of this embodiment, the determination module 2710 is used to determine the target uplink channel resources through at least one of the following methods.

[0441] Method 1: Determination module 2710 is used to determine the target uplink channel resource among the uplink channel resources configured by the first configuration when at least two uplink channel resources both correspond to the first configuration; and to determine the target uplink channel resource among the uplink channel resources configured by the second configuration when at least two uplink channel resources both correspond to the second configuration.

[0442] Taking the uplink channel resource as an example, FIG19 shows a schematic diagram of determining PUCCH resources provided by an exemplary embodiment of the present application. Exemplarily, the first configuration indicates PUCCH resource set 1 and PUCCH resource set 2. Each PUCCH resource in PUCCH resource set 1 occupies 2 symbols, and each PUCCH resource in PUCCH resource set 2 occupies 4 symbols (not shown in the figure). Assuming that PUCCH1 and PUCCH2 both belong to PUCCH resource set 1, if at least two UCI multiplexed payloads correspond to PUCCH resource set 2, the target PUCCH resource is a PUCCH resource selected from PUCCH resource set 2.

[0443] Method 2: Determination module 2710 is used to determine the target uplink channel resource among the uplink channel resources configured by the first configuration when at least two uplink channel resources correspond to the first configuration and the second configuration; or, to determine the target uplink channel resource among the uplink channel resources configured by the second configuration when at least two uplink channel resources correspond to the first configuration and the second configuration.

[0444] Taking the uplink channel resource as an example of a PUCCH resource, FIG20 shows a schematic diagram of determining a PUCCH resource provided by an exemplary embodiment of the present application. Exemplarily, the first configuration indicates that there are PUCCH resource set 1 and PUCCH resource set 2, each PUCCH resource in PUCCH resource set 1 occupies 2 symbols, and each PUCCH resource in PUCCH resource set 2 occupies 4 symbols (not shown in the figure). The second configuration indicates that there are PUCCH resource set 3 and PUCCH resource set 4, each PUCCH resource in PUCCH resource set 3 occupies 2 symbols, and each PUCCH resource in PUCCH resource set 4 occupies 4 symbols (not shown in the figure).

[0445] Assume that PUCCH1 belongs to PUCCH resource set 1 and corresponds to the first configuration; and PUCCH2 belongs to PUCCH resource set 3 and corresponds to the second configuration. If the target PUCCH resource after multiplexing always uses the second configuration, and if at least two UCI multiplexed payloads correspond to PUCCH resource set 2 or 4, the target PUCCH resource is a PUCCH resource selected from PUCCH resource set 4.

[0446] If at least two PUCCH resources correspond to the first configuration and the second configuration, and the target PUCCH resource corresponds to the first configuration, taking the first configuration corresponding to the SBFD symbol as an example, the middle subband of the SBFD symbol can be configured as an uplink subband to ensure that the target PUCCH resource is within the valid uplink resource (valid UL resource); or, if at least two PUCCH resources correspond to the first configuration and the second configuration, and the target PUCCH resource corresponds to the second configuration, taking the second configuration corresponding to the non-SBFD symbol as an example, uplink resource fragmentation can be avoided while reducing link interference.

[0447] Mode 3: The determination module 2710 is configured to determine the target uplink channel resource according to at least one of the following when the at least two uplink channel resources correspond to the first configuration and the second configuration and a dynamically scheduled first uplink channel resource exists among the at least two uplink channel resources:

[0448] The time domain resource type corresponding to the first uplink channel resource; the configuration corresponding to the first uplink channel resource; and the DCI corresponding to the first uplink channel resource.

[0449] Case 1: determining the target uplink channel resource according to the time domain resource type corresponding to the first uplink channel resource.

[0450] In one possible design of this embodiment, the determining module 2710 is configured to determine a target uplink channel resource in the uplink channel resources configured in the first configuration, when at least two uplink channel resources correspond to the first configuration and the second configuration, a dynamically scheduled first uplink channel resource exists among the at least two uplink channel resources, and the first uplink channel resource is located in the first type of time domain resources;

[0451] When at least two uplink channel resources correspond to a first configuration and a second configuration, there is a dynamically scheduled first uplink channel resource among the at least two uplink channel resources, and the first uplink channel resource is located in the second type of time domain resources, determine the target uplink channel resource among the uplink channel resources configured by the second configuration.

[0452] Taking the uplink channel resource as a PUCCH resource and the time domain resource as a symbol as an example, when the first PUCCH resource is located in an SBFD symbol, the target PUCCH resource is determined in the PUCCH resources configured by the first configuration; when the first PUCCH resource is located in a non-SBFD symbol, the target PUCCH resource is determined in the PUCCH resources configured by the second configuration.

[0453] FIG21 is a schematic diagram illustrating a method for determining PUCCH resources according to an exemplary embodiment of the present application. Assuming that at least two PUCCH resources are PUCCH 1 and PUCCH 2, and that PUCCH 1 corresponds to a first configuration and PUCCH 2 corresponds to a second configuration, the first PUCCH resource dynamically scheduled by DCI is PUCCH 1. When PUCCH 1 is located in an SBFD symbol, a target PUCCH resource is determined within the PUCCH resources configured in the first configuration. For example, a PUCCH resource set in the first configuration is determined based on the multiplexed payload of at least two UCIs, and the target PUCCH resource is determined within the PUCCH resource set.

[0454] Case 2: Determine the target uplink channel resource according to the configuration corresponding to the first uplink channel resource.

[0455] In one possible design of this embodiment, the determining module 2710 is configured to determine a target uplink channel resource among the uplink channel resources configured in the first configuration, when at least two uplink channel resources correspond to a first configuration and a second configuration, and a dynamically scheduled first uplink channel resource exists among the at least two uplink channel resources, and the first uplink channel resource corresponds to the first configuration;

[0456] When at least two uplink channel resources correspond to a first configuration and a second configuration, a dynamically scheduled first uplink channel resource exists among the at least two uplink channel resources, and the first uplink channel resource corresponds to the second configuration, a target uplink channel resource is determined among the uplink channel resources configured by the second configuration.

[0457] Continuing with Figure 21, assuming that at least two PUCCH resources are PUCCH 1 and PUCCH 2, and PUCCH 1 corresponds to a first configuration and PUCCH 2 corresponds to a second configuration, the first PUCCH resource dynamically scheduled by DCI is PUCCH 1. When PUCCH 1 corresponds to the first configuration, a target PUCCH resource is determined within the PUCCH resources configured in the first configuration. For example, a PUCCH resource set in the first configuration is determined based on the multiplexed payload of at least two UCIs, and the target PUCCH resource is determined within this PUCCH resource set.

[0458] Case three: determining the target uplink channel resource according to the DCI corresponding to the first uplink channel resource.

[0459] In a possible design of this embodiment, the determination module 2710 is configured to determine the target uplink channel resource in the uplink channel resources configured by the first configuration, when at least two uplink channel resources correspond to the first configuration and the second configuration, there is a dynamically scheduled first uplink channel resource among the at least two uplink channel resources, and the second DCI indicates the first configuration; and / or,

[0460] When at least two uplink channel resources correspond to a first configuration and a second configuration, a dynamically scheduled first uplink channel resource exists among the at least two uplink channel resources, and a second DCI indicates the second configuration, a target uplink channel resource is determined among the uplink channel resources configured by the second configuration.

[0461] In the case where there is a dynamically scheduled first uplink channel resource among at least two uplink channel resources, the target uplink channel resource is determined according to the time domain resource type corresponding to the first uplink channel resource, or the configuration corresponding to the first uplink channel resource, or the DCI corresponding to the first uplink channel resource, which is more flexible and adaptable to the needs of different scenarios.

[0462] In a possible design of this embodiment, the second indication field in the second DCI is used to indicate the first configuration or the second configuration; or, the DCI format in the second DCI is used to indicate the first configuration or the second configuration; or, the RNTI used to scramble the second DCI is used to indicate the first configuration or the second configuration; or, the resource location or resource index carrying the second DCI is used to indicate the first configuration or the second configuration.

[0463] Exemplarily, the second indication field indicates the first configuration or the second configuration through one bit, for example, when the bit value is 0, it indicates the first configuration, and when the bit value is 1, it indicates the second configuration. When the DCI format of the second DCI is format A, it is used to indicate the first configuration; when the DCI format of the second DCI is format B, it is used to indicate the second configuration. When the RNTI is the first RNTI, it is used to indicate the first configuration; when the RNTI is the second RNTI, it is used to indicate the second configuration. In the case where the resource index is a CCE index, when the CCE index number is 1, it is used to indicate the first configuration; when the CCE index number is 2, it is used to indicate the second configuration.

[0464] Through the above different indication methods, the first configuration or the second configuration can be accurately indicated in different situations.

[0465] If there are multiple dynamically scheduled first uplink channel resources, the configuration information corresponding to the target uplink channel resource is determined according to the indication of the last DCI among the multiple DCIs corresponding to the multiple dynamically scheduled first uplink channel resources, or is determined according to the configuration information corresponding to the uplink channel resource indicated by the last DCI.

[0466] In a possible design of this embodiment, the determining module 2710 is configured to determine a target uplink channel resource among the uplink channel resources configured by the first configuration, when at least two uplink channel resources correspond to the first configuration and the second configuration, at least two first uplink channel resources dynamically scheduled by at least two second DCIs exist among the at least two uplink channel resources, and the last DCI indicates the first configuration;

[0467] When at least two uplink channel resources correspond to a first configuration and a second configuration, there are at least two first uplink channel resources dynamically scheduled by at least two second DCIs among the at least two uplink channel resources, and the last DCI indicates the second configuration, the target uplink channel resource is determined among the uplink channel resources configured by the second configuration.

[0468] The at least two second DCIs correspond one-to-one to the at least two first uplink channel resources, and the last DCI is the last one of the at least two second DCIs.

[0469] Taking the uplink channel resource as an example, FIG22 shows a schematic diagram of determining PUCCH resources provided by an exemplary embodiment of the present application. At least two PUCCH resources are PUCCH 1 and PUCCH 2. When PUCCH 1 corresponds to the first configuration and PUCCH 2 corresponds to the second configuration, DCI 1 indicates PUCCH 1, DCI 2 indicates PUCCH 2, and the second DCI is the last DCI, DCI 2. When DCI 2 indicates the first configuration and the PRI indication field value is 00, a target PUCCH resource set is determined from the multiple PUCCH resource sets indicated by the first configuration based on the multiplexed payloads of at least two UCIs. PUCCH 3 (target PUCCH resource) is the first PUCCH resource in the target PUCCH resource set. The multiple PUCCH resource sets correspond to different payloads or PUCCH formats.

[0470] In a possible design of this embodiment, the device for determining the uplink channel resources does not expect that the configurations corresponding to at least two uplink channel resources are different; or, the device for determining the uplink channel resources expects that the configurations corresponding to at least two uplink channel resources are the same; or, the device for determining the uplink channel resources expects that at least two uplink channel resources both correspond to the first configuration; or, the device for determining the uplink channel resources expects that at least two uplink channel resources both correspond to the second configuration.

[0471] In a possible design of this embodiment, the device for determining the uplink channel resources does not expect to configure or indicate the target uplink channel resources through the network device, and the target uplink channel resources are in a time slot that includes both the first type of time domain resources and the second type of time domain resources.

[0472] In a possible design of this embodiment, the configurations corresponding to at least two uplink channel resources include a first configuration and / or a second configuration.

[0473] In a possible design of this embodiment, the uplink channel resource is a PUCCH resource. When the configurations corresponding to at least two PUCCH resources are different and the UCI corresponding to the at least two PUCCH resources are not multiplexed, two HARQ-ACK codebooks are constructed. HARQ-ACK codebook 1 corresponds to the first configuration, and HARQ-ACK codebook 2 corresponds to the second configuration.

[0474] In a possible design of this embodiment, the receiving module 2720 is used to receive the first configuration and the second configuration.

[0475] In a possible design of this embodiment, the receiving module 2720 is used to receive a first configuration parameter and a second configuration parameter, the first configuration parameter corresponds to the first configuration, and the second configuration parameter corresponds to the second configuration; or, to receive a first configuration parameter and an offset value, the first configuration parameter corresponds to the first configuration, and the configuration parameter after the first configuration parameter is offset based on the offset value corresponds to the second configuration; or, to receive a group of configuration parameters, a group of configuration parameters includes a first configuration parameter and a second configuration parameter, the first configuration parameter corresponds to the first configuration, and the second configuration parameter corresponds to the second configuration.

[0476] The separate configuration in the above method includes configuring the first configuration parameter and the second configuration parameter separately; it also includes configuring the first configuration parameter, and the configuration parameter corresponding to the second configuration is obtained by offsetting the first configuration parameter based on the offset value; it also includes configuring a group of configuration parameters, which includes 2 parts, the first part of the parameters corresponds to the first configuration parameter, and the second part of the parameters corresponds to the second configuration parameter.

[0477] In a possible design of this embodiment, the offset value is a resource block (RB) offset (RB offset) or an RB offset list (RB offset list). The RB offset is used to adjust the frequency domain resources of the PUCCH resources. Taking the first configuration corresponding to SBFD symbols and the second configuration corresponding to non-SBFD symbols as an example, the RB offset is the frequency domain offset of the PUCCH resources located in the SBFD symbols relative to the PUCCH resources located in the non-SBFD symbols, or the RB offset is the frequency domain offset of the PUCCH resources located in the non-SBFD symbols relative to the PUCCH resources located in the SBFD symbols.

[0478] This embodiment uses one determination module 2710 and one receiving module 2720 as an example for illustration. The number of determination modules 2710 and receiving modules 2720 is not limited. For an introduction to the function of the determination module 2710, refer to the content of step 610 in the embodiment of FIG. 6 . For an introduction to the function of the receiving module 2720, refer to the content of step 610 in the embodiment of FIG. 6 .

[0479] FIG28 shows a block diagram of an apparatus for determining uplink channel resources provided by an exemplary embodiment of the present application. The apparatus can be implemented as a terminal device, or as a part of a terminal device, through software or hardware, or a combination of both. The apparatus includes:

[0480] The determination module 2810 is configured to determine a target uplink channel resource from the uplink channel resources configured in at least one of the first configuration, the second configuration, and the third configuration.

[0481] Among them, the third configuration is used to configure the relevant parameters of the uplink channel resources in the time unit having the first type of time domain resources and the second type of time domain resources, the first configuration is used to configure the relevant parameters of the uplink channel resources in the time unit having (only) the first type of time domain resources, and the second configuration is used to configure the relevant parameters of the uplink channel resources in the time unit having (only) the second type of time domain resources.

[0482] In a possible design of this embodiment, the determination module 2810 is used to determine the target uplink channel resource based on the time domain resource where the target uplink channel resource is located.

[0483] The target uplink channel resource is determined according to the time domain resource where the target uplink channel resource is located, and the implementation is simple.

[0484] In a case where the time domain resource where the target uplink channel resource is located is a first type of time domain resource, the target uplink channel resource is determined among the uplink channel resources configured by the first configuration; in a case where the time domain resource where the target uplink channel resource is located is a second type of time domain resource, the target uplink channel resource is determined among the uplink channel resources configured by the second configuration; in a case where the time domain resource where the target uplink channel resource is located includes first type of time domain resources and second type of time domain resources, the target uplink channel resource is determined among the uplink channel resources configured by the third configuration.

[0485] Taking the first configuration, the second configuration and the third configuration corresponding to the first time slot type, the second time slot type and the third time slot type respectively as an example, the first time slot type is a time slot type that only includes SBFD symbols, the second time slot type is a time slot type that only includes non-SBFD symbols, and the third time slot type is a time slot type that includes both SBFD symbols and non-SBFD symbols.

[0486] In a possible design of this embodiment, the uplink channel resources used by at least one of the SR, CSI report, and SPS HARQ-ACK signals corresponding to the first configuration are the uplink channel resources configured by the first configuration; the uplink channel resources used by at least one of the SR, CSI report, and SPS HARQ-ACK signals corresponding to the second configuration are the uplink channel resources configured by the second configuration; and the uplink channel resources used by at least one of the SR, CSI report, and SPS HARQ-ACK signals corresponding to the third configuration are the uplink channel resources configured by the third configuration.

[0487] In a possible design of this embodiment, the receiving module 2820 is used to receive the first configuration and the third configuration; or, receive the second configuration and the third configuration; or, receive the first configuration, the second configuration, and the third configuration.

[0488] In some embodiments, the receiving module 2820 is further configured to receive at least one of the first DCI, the second DCI, and higher layer signaling.

[0489] This embodiment uses one determination module 2810 and one receiving module 2820 as an example. The number of determination modules 2810 and receiving modules 2820 is not limited. For an introduction to the function of determination module 2810, refer to step 2410 in the embodiment of FIG. 24 . For an introduction to the function of receiving module 2820, refer to step 2410 in the embodiment of FIG. 24 .

[0490] FIG29 shows a block diagram of a resource configuration sending device provided by an exemplary embodiment of the present application. The device can be implemented as a network device or as a part of a network device through software or hardware or a combination of both. The device includes:

[0491] The sending module 2910 is used to send a first configuration and a second configuration; wherein the first configuration and the second configuration are used to configure relevant parameters of uplink channel resources, the first configuration corresponds to the first type of time domain resources, and the second configuration corresponds to the second type of time domain resources.

[0492] In a possible design of this embodiment, the sending module 2910 is used to send a first configuration parameter and a second configuration parameter, where the first configuration parameter corresponds to the first configuration and the second configuration parameter corresponds to the second configuration; or, to send a first configuration parameter and an offset value, where the first configuration parameter corresponds to the first configuration and the configuration parameter after the first configuration parameter is offset based on the offset value corresponds to the second configuration; or, to send a group of configuration parameters, where a group of configuration parameters includes a first configuration parameter and a second configuration parameter, where the first configuration parameter corresponds to the first configuration and the second configuration parameter corresponds to the second configuration.

[0493] The separate configuration in the above method includes configuring the first configuration parameter and the second configuration parameter separately; it also includes configuring the first configuration parameter, and the configuration parameter corresponding to the second configuration is obtained by offsetting the first configuration parameter based on the offset value; it also includes configuring a group of configuration parameters, which includes 2 parts, the first part of the parameters corresponds to the first configuration parameter, and the second part of the parameters corresponds to the second configuration parameter.

[0494] In a possible design of this embodiment, the offset value is a resource block (RB) offset (RB offset). The RB offset is used to adjust the frequency domain resources of the PUCCH resources. Taking the first configuration corresponding to SBFD symbols and the second configuration corresponding to non-SBFD symbols as an example, the uplink channel resources are PUCCH resources as an example for explanation. The RB offset is the frequency domain offset of the PUCCH resources located in the SBFD symbols relative to the PUCCH resources located in the non-SBFD symbols, or the RB offset is the frequency domain offset of the PUCCH resources located in the non-SBFD symbols relative to the PUCCH resources located in the SBFD symbols.

[0495] In one possible design of this embodiment, the uplink channel resources include at least one of the following: PUCCH resources, physical uplink shared channel (PUSCH) resources, physical random access channel (PRACH) resources, etc. This embodiment of the present application is not limited to this, and generally uses PUCCH resources as an example for description.

[0496] In one possible design of this embodiment, the time domain resources include at least one of the following: a symbol, a symbol group, a time slot, a sub-time slot, a frame, and a subframe. The specific type of time domain resources is not limited in the embodiments of the present application. Generally, the first configuration corresponds to a first type of symbol, and the second configuration corresponds to a second type of symbol. For example, the first configuration corresponds to an SBFD symbol, and the second configuration corresponds to a non-SBFD symbol. An SBFD symbol is a symbol that includes at least one of an uplink subband, a downlink subband, and a guard band, while a non-SBFD symbol is a symbol that does not include any of the above subbands.

[0497] In a possible design of this embodiment, the first configuration is applicable to time slots in which all symbols are SBFD symbols, and also to time slots in which some symbols are SBFD symbols; the second configuration is applicable to time slots in which all symbols are non-SBFD symbols, and also to time slots in which some symbols are non-SBFD symbols.

[0498] In a possible design of this embodiment, the first configuration and the second configuration share time domain resource parameters.

[0499] In a possible design of this embodiment, the first configuration and the second configuration do not share time domain resource parameters.

[0500] In one possible design of this embodiment, the target uplink channel resource is a resource used to send uplink control information (UCI). In one possible design of this embodiment, the target uplink channel resource is a resource used to feedback HARQ-ACK or a HARQ-ACK codebook. In one possible design of this embodiment, the target uplink channel resource is a resource used when multiplexing at least two UCIs.

[0501] In a possible design of this embodiment, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), orthogonal cover code (Orthogonal Cover Code, OCC) parameters, time domain resource parameters (e.g., starting symbol index startingSymbolIndex, number of symbols nrofSymbols).

[0502] In a possible design of this embodiment, in the first configuration and the second configuration, the time domain resource configuration corresponding to the associated uplink channel resource is the same. In this case, the relevant parameters determined for the target uplink channel resource according to the first configuration or the second configuration do not include the time domain resource parameter.

[0503] In one possible design of this embodiment, the terminal device expects that the time domain resource configuration corresponding to the associated uplink channel resources in the first configuration and the second configuration is the same; and / or the terminal device does not expect that the time domain resource configuration corresponding to the associated uplink channel resources in the first configuration and the second configuration is different. That is, the time domain resource parameters are carried in the first configuration and the second configuration and are exactly the same in both configurations.

[0504] The resource configuration sending device will try to configure in accordance with the terminal device's expectations, but it may not be 100% in accordance with the terminal device's expectations. In some cases, the resource configuration sending device may send configuration information in a manner that the terminal device does not expect. In this case, how the terminal device handles the unexpected configuration information is not limited by this application, and for example, it can be implemented independently by the terminal device.

[0505] In a possible design of this embodiment, the time domain resource configuration corresponding to the associated uplink channel resources does not need to be configured separately, so that the time domain resources are the same regardless of which configuration the terminal device uses to determine the uplink channel resources.

[0506] In a possible design of this embodiment, the time domain resource parameters shared by the first configuration and the second configuration are additionally configured by the sending device of the resource configuration, or agreed upon by the communication protocol. In this case, the first configuration and the second configuration do not include the time domain resource parameters.

[0507] In a possible design of this embodiment, the associated uplink channel resources correspond to the same uplink channel resource identifier; or, the two uplink channel resource identifiers corresponding to the associated uplink channel resources have a pre-agreed corresponding relationship.

[0508] In one possible design of this embodiment, an uplink channel resource is a PUCCH resource as an example. A first PUCCH resource set is configured in a first configuration, and a second PUCCH resource set is configured in a second configuration. The first PUCCH resource set and the second PUCCH resource set are from different configurations, but there are associated PUCCH resources in the two PUCCH resource sets.

[0509] In a possible design of this embodiment, uplink channel resources corresponding to the same uplink channel resource identification (IDentification, ID) are associated; or, uplink channel resources of two uplink channel resource IDs having a pre-agreed corresponding relationship are associated.

[0510] The associated uplink channel resources may correspond to the same uplink channel resource identifier, or may be two uplink channel resource IDs with a pre-agreed corresponding relationship, which can adapt to the association requirements of uplink channel resources in different situations.

[0511] In one possible design of this embodiment, the relevant parameters include at least one of the following: frequency domain resource parameters (e.g., starting physical resource block startingPRB, second hop physical resource block secondHopPRB), maximum code rate (maxCodeRate), and orthogonal cover code (OCC) parameters. The relevant parameters do not include time domain resource parameters, such as starting symbol index (startingSymbolIndex) and number of symbols (nrofSymbols). The time domain resource parameters are configured through other configurations, not through the first configuration or the second configuration.

[0512] When the relevant parameters do not include time domain resource parameters, they will be configured through other configurations, which is more flexible.

[0513] In a possible design of this embodiment, the PUCCH resources used by at least one of the signals including the Scheduling Request (SR), Channel State Information (CSI) report, and Semi-Persistent Scheduling Hybrid Automatic Repeat reQuest ACKnowledgment (SPS HARQ-ACK) corresponding to the first configuration are the PUCCH resources configured by the first configuration; the PUCCH resources used by at least one of the signals including the SR, CSI report, and SPS HARQ-ACK corresponding to the second configuration are the PUCCH resources configured by the second configuration.

[0514] In a possible design of this embodiment, relevant parameters of SR, CSI report, and SPS HARQ-ACK are configured in their respective corresponding configurations (first configuration or second configuration), for example, in their respective corresponding PUCCH configurations (PUCCH-Config).

[0515] In a possible design of this embodiment, the sending module 2910 is used to send a first DCI, where the first DCI is used to indicate the first configuration or the second configuration, and to indicate the target uplink channel resources used by the terminal device.

[0516] In a possible design of this embodiment, the manner in which the first DCI indicates the first configuration or the second configuration includes explicit indication and implicit indication.

[0517] Explicit indication: In a possible design of this embodiment, the first DCI includes a first indication field, and the first indication field is used to indicate the first configuration or the second configuration.

[0518] In some embodiments, based on a DCI format known before the filing date, the first indication field is a newly added indication field, or part of the bits of a known indication field.

[0519] In a possible design of this embodiment, the first indication field is an indication field added outside the uplink channel resource indication field, or the first indication field is part of the bits of the uplink channel resource indication field.

[0520] When the first indication field is a newly added indication field outside the uplink channel resource indication field, it can indicate the first configuration or the second configuration more flexibly; when the first indication field is a partial bit of the uplink channel resource indication field, such as the highest bit or the lowest bit of the PRI indication field, no additional DCI overhead is added.

[0521] In a possible design of this embodiment, the first indication field is part of the bits of the uplink channel resource indication field, including: the first indication field is the highest bit or the lowest bit of the PRI indication field.

[0522] The highest bit or the lowest bit of the PRI indication field is used to indicate the first configuration or the second configuration, and the remaining bits in the PRI indication field are used to indicate the PUCCH resources in the first configuration or the second configuration.

[0523] In a possible design of this embodiment, when the time domain resources include a sub-time domain resource type, the sub-time domain resource type is used to indicate the first configuration or the second configuration; when the time domain resources include at least two sub-time domain resource types, the first DCI includes a first indication field, and the first indication field is used to indicate the first configuration or the second configuration.

[0524] Exemplarily, when a time slot includes only one symbol type, the first configuration or the second configuration is determined by the symbol type, and all bits of the first indicator field (PRI indicator field) are used to indicate the PUCCH resource. When a time slot includes at least two symbol types, some bits in the first indicator field are used to indicate the first configuration or the second configuration, and the remaining bits are used to indicate the target PUCCH resource. As shown in Figure 7, when a time slot includes only SBFD symbols, the first configuration is determined by the symbol type. When a time slot includes only non-SBFD symbols, the second configuration is determined by the symbol type. When a time slot includes both SBFD and non-SBFD symbols, the highest bit in the first indicator field is used to indicate the first configuration or the second configuration, and the remaining bits are used to indicate the target PUCCH resource.

[0525] Implicit indication: In a possible design of this embodiment, the DCI format of the first DCI is used to indicate the first configuration or the second configuration; or, the DCI format of the first DCI is associated with the first configuration or the second configuration; or, the Radio Network Temporary Identifier sequence (RNTI) used to scramble the first DCI is used to indicate the first configuration or the second configuration; or, the RNTI used to scramble the first DCI is associated with the first configuration or the second configuration; or, the resource position or resource index of the downlink control resource carrying the first DCI is used to indicate the first configuration or the second configuration; or, the resource position or resource index of the downlink control resource carrying the first DCI is associated with the first configuration or the second configuration.

[0526] Exemplarily, when the DCI format of the first DCI is format A, it is used to indicate the first configuration; when the DCI format of the first DCI is format B, it is used to indicate the second configuration. When the RNTI is the first RNTI, it is used to indicate the first configuration; when the RNTI is the second RNTI, it is used to indicate the second configuration.

[0527] For example, when the resource index is a control channel element (CCE) index, when the CCE index number is 1, it indicates the first configuration; when the CCE index number is 2, it indicates the second configuration. In one embodiment, the CCE index number may refer to the lowest CCE index number where the PDCCH is located, or the highest CCE index number where the PDCCH is located.

[0528] Indicating the first configuration or the second configuration in different ways can meet the needs of different scenarios without requiring additional DCI overhead.

[0529] In a possible design of this embodiment, the sending module 2910 is used to send high-layer signaling to the terminal device, where the high-layer signaling is used to indicate the first configuration or the second configuration.

[0530] In one possible design of this embodiment, a first configuration or a second configuration is used in a time slot including at least two types of time domain resources, through high-layer signaling configuration. The high-layer refers to a protocol layer above the physical layer, such as a system information block (SIB), radio resource control (RRC), and media access control (MAC).

[0531] The resource configuration sending device can support a variety of configuration methods for high-level signaling, allowing for configuration based on actual needs without requiring additional DCI overhead. For example, using the PUCCH resource as the uplink channel resource, the advantage of agreeing on the first configuration is that it ensures that the PUCCH resource falls within the valid uplink resource (UL resource). The advantage of agreeing on the second configuration is that it avoids uplink resource fragmentation and reduces link interference.

[0532] For example, if the time slots within a period of time only include SBFD symbols, the sending device of the resource configuration instructs the terminal device to use the first configuration through high-layer signaling. For another example, if the time slots within another period of time only include non-SBFD symbols, the sending device of the resource configuration instructs the terminal device to use the second configuration through high-layer signaling. For another example, if the high-layer signaling carries the window parameters of at least one time window and the correspondence between each time window and the first configuration or the second configuration, the terminal device determines the first configuration or the second configuration to use for the current time window based on the above correspondence. The window parameters of the time window include at least one of: starting position, ending position, length, cycle start point, and cycle length.

[0533] In a possible design of this embodiment, the first configuration or the second configuration is used to determine the target uplink channel resource for use by the terminal device; the target uplink channel resource is the uplink channel resource used when at least two UCIs of the terminal device are multiplexed, and at least two uplink channel resources corresponding to at least two UCIs before multiplexing are in the same time unit, or at least two uplink channel resources overlap.

[0534] In a possible design of this embodiment, the determination module 2920 is used to determine the target uplink channel resources used by the terminal device, wherein the target uplink channel resources are the uplink channel resources used when at least two UCIs of the terminal device are multiplexed.

[0535] In a possible design of this embodiment, after determining the target uplink channel resource used by the terminal device, the receiving module 2930 is used to receive at least two multiplexed UCIs on the target uplink channel resource.

[0536] In a possible design of this embodiment, the target uplink channel resource is the uplink channel resource used when at least two UCIs of the terminal device are multiplexed, and at least two uplink channel resources corresponding to at least two UCIs before multiplexing are in the same time unit, or at least two uplink channel resources overlap.

[0537] Taking the uplink channel resource as an example, which is a PUCCH resource, the terminal device will transmit at least two PUCCH resources (carrying at least two UCIs) in the first time slot, and at least two PUCCH resources overlap (partially overlap or fully overlap), or at least two PUCCH resources are in the same time unit (time slot, sub-time slot, symbol group, etc.), where the first time slot is a mixed symbol time slot type, i.e., including SBFD symbols and non-SBFD symbols, then the terminal device multiplexes at least two UCIs in the target PUCCH resource for transmission.

[0538] In one possible design of this embodiment, when the at least two uplink channel resources include a dynamically scheduled first uplink channel resource, the resource configuration sending device determines, for the terminal device, at least two target uplink channel resources for UCI multiplexing based on a related art multiplexing resource determination method. Sending module 2910 is further configured to send a second DCI, where the second DCI is used to indicate the first configuration or the second configuration corresponding to the target uplink channel resource, and is used to indicate the first uplink channel resource.

[0539] Case 1: The time domain resource type corresponding to the first uplink channel resource indicated by the second DCI is the same as the time domain resource type corresponding to the target uplink channel resource. That is, when the target uplink channel resource corresponds to an SBFD symbol, the first uplink channel resource also corresponds to an SBFD symbol; when the target uplink channel resource corresponds to a non-SBFD symbol, the first uplink channel resource also corresponds to a non-SBFD symbol.

[0540] Case 2: The configuration corresponding to the first uplink channel resource indicated by the second DCI is the same as the configuration corresponding to the target uplink channel resource. That is, when the target uplink channel resource corresponds to the first configuration, the first uplink channel resource also corresponds to the first configuration; when the target uplink channel resource corresponds to the second configuration, the first uplink channel resource also corresponds to the second configuration.

[0541] Case three: The second indication field in the second DCI is used to indicate the first configuration or the second configuration; or, the DCI format in the second DCI is used to indicate the first configuration or the second configuration; or, the RNTI used to scramble the second DCI is used to indicate the first configuration or the second configuration; or, the resource location or resource index carrying the second DCI is used to indicate the first configuration or the second configuration.

[0542] Exemplarily, the second indication field indicates the first configuration or the second configuration through one bit. For example, when the bit value is 0, it indicates the first configuration, and when the bit value is 1, it indicates the second configuration. When the DCI format of the second DCI is format A, it is used to indicate the first configuration; when the DCI format of the second DCI is format B, it is used to indicate the second configuration. When the RNTI is the first RNTI, it is used to indicate the first configuration; when the RNTI is the second RNTI, it is used to indicate the second configuration. In the case where the resource index is a CCE index, when the CCE index number is 1, it is used to indicate the first configuration; when the CCE index number is 2, it is used to indicate the second configuration.

[0543] Through the above different indication methods, the first configuration or the second configuration can be accurately indicated in different situations.

[0544] In a possible design of this embodiment, when at least two first uplink channel resources are dynamically scheduled by at least two second DCIs, the sending module 2910 is used to send the last DCI, and the last DCI is used to indicate the first configuration or the second configuration corresponding to the target uplink channel resource; wherein the last DCI is the last one of the at least two second DCIs.

[0545] In a possible design of this embodiment, the determination module 2920 is used to determine the target uplink channel resources used by the terminal device among the uplink channel resources configured by the first configuration or the second configuration.

[0546] In a possible design of this embodiment, the determination module 2920 is used to determine the target uplink channel resources used by the terminal device among the uplink channel resources configured by the first configuration when the first configuration is used based on the communication protocol agreement; and to determine the target uplink channel resources used by the terminal device among the uplink channel resources configured by the second configuration when the second configuration is used based on the communication protocol agreement.

[0547] The communication protocol stipulates that the transmitting device does not need resource configuration, and there is no additional DCI overhead. Taking the uplink channel resource as an example, the benefit of using the first configuration is to ensure that the PUCCH resource falls within the valid uplink resource (valid UL resource). The benefit of using the second configuration is to avoid uplink resource fragmentation and reduce link interference.

[0548] For example, if a time slot within a certain period includes only SBFD symbols, the communication protocol stipulates the use of the first configuration. Another example is that a time slot within another period includes only non-SBFD symbols, and the communication protocol stipulates the use of the second configuration. In another example, if the communication protocol stipulates window parameters for at least one time window and a correspondence between each time window and the first or second configuration, the terminal device determines whether to use the first or second configuration for the current time window based on this correspondence. The window parameters of a time window include at least one of: a starting position, an ending position, a length, a period start point, and a period length.

[0549] In a possible design of this embodiment, the determination module 2920 is used to determine the target uplink channel resources used by the terminal device among the uplink channel resources configured by the first configuration when at least two uplink channel resources both correspond to the first configuration; and to determine the target uplink channel resources used by the terminal device among the uplink channel resources configured by the second configuration when at least two uplink channel resources both correspond to the second configuration.

[0550] Taking the uplink channel resource as the PUCCH resource as an example, Figure 19 shows a schematic diagram of determining the PUCCH resource provided by an exemplary embodiment of the present application. The at least two PUCCH resources include PUCCH 1 and PUCCH 2. When PUCCH 1 and PUCCH 2 both correspond to the first configuration, the target PUCCH resource used by the terminal device is determined among the PUCCH resources configured by the first configuration.

[0551] If the at least two PUCCH resources both correspond to the first configuration, the target PUCCH resource corresponds to the first configuration; if the at least two PUCCH resources both correspond to the second configuration, the target PUCCH resource corresponds to the second configuration.

[0552] In a possible design of this embodiment, the determination module 2920 is used to determine the target uplink channel resources used by the terminal device among the uplink channel resources configured by the first configuration when at least two uplink channel resources correspond to the first configuration and the second configuration; or, to determine the target uplink channel resources used by the terminal device among the uplink channel resources configured by the second configuration when at least two uplink channel resources correspond to the first configuration and the second configuration.

[0553] Taking the uplink channel resource as the PUCCH resource as an example, Figure 20 shows a schematic diagram of determining the PUCCH resource provided by an exemplary embodiment of the present application. The at least two PUCCH resources include PUCCH 1 and PUCCH 2. When PUCCH 1 and PUCCH 2 correspond to the first configuration and the second configuration, the target PUCCH resource used by the terminal device is determined in the PUCCH resources configured by the first configuration.

[0554] If at least two PUCCH resources correspond to the first configuration and the second configuration, and the target PUCCH resource corresponds to the first configuration, taking the first configuration corresponding to the SBFD symbol as an example, the middle subband of the SBFD symbol can be configured as an uplink subband to ensure that the target PUCCH resource is within the valid uplink resource (valid UL resource); or, if at least two PUCCH resources correspond to the first configuration and the second configuration, and the target PUCCH resource corresponds to the second configuration, taking the second configuration corresponding to the non-SBFD symbol as an example, uplink resource fragmentation can be avoided while reducing link interference.

[0555] In one possible design of this embodiment, a UE is provided first and second for each of {PUCCH-ResourceSet,PUCCH-Resource except the startingSymbolIndex and nrofSymbols}, respectively for use with PUCCH (SR, CSI, HARQ-ACK)occupying the first symbol type and the second symbol type respectively,where,the first symbol type and second symbol type are SBFD symbol type and non-SBFD symbol type.

[0556] In one possible design of this embodiment, a first configuration and a second configuration are provided for each of {PUCCH-ResourceSet,PUCCH-Resource}, respectively for use with PUCCH (SR, CSI, HARQ-ACK) occupying the first symbol type and the second symbol type respectively, where the first symbol type is SBFD symbol type and the second symbol type is non-SBFD symbol type.UE expects that the corresponding PUCCH resource in the first config and the second config to occupy the same symbols.

[0557] In a possible design of this embodiment, the terminal device is configured with a second configuration parameter and an offset value, the second configuration parameter corresponds to the second configuration, the offset value is a resource block (RB) offset (RB offset), and the RB offset is used to adjust the frequency domain resources of the PUCCH resources. Taking the first configuration corresponding to the SBFD symbol and the second configuration corresponding to the non-SBFD symbol as an example, the RB offset is the frequency domain offset of the PUCCH resource located in the SBFD symbol relative to the PUCCH resource located in the non-SBFD symbol.

[0558] In a possible design of this embodiment, the terminal device is configured with a first configuration parameter and an offset value, the first configuration parameter corresponds to the first configuration, and the offset value is an RB offset. Taking the first configuration corresponding to the SBFD symbol and the second configuration corresponding to the non-SBFD symbol as an example, the RB offset is the frequency domain offset of the PUCCH resource located in the non-SBFD symbol relative to the PUCCH resource located in the SBFD symbol.

[0559] Figure 16 shows a schematic diagram of the PUCCH resource offset provided by an exemplary embodiment of the present application. Taking the case where the terminal device is configured with the second configuration parameter (PUCCH configuration 3) and the offset value, the offset value is an RB offset, the first configuration corresponds to the SBFD symbol, and the second configuration corresponds to the non-SBFD symbol as an example, the frequency domain resource parameters in PUCCH configuration 3 are added with the offset value and together with other resource parameters form PUCCH configuration 4.

[0560] Figure 17 shows a schematic diagram of a PUCCH resource offset provided by an exemplary embodiment of the present application. In a possible design of this embodiment, the starting position of the PUCCH resource corresponding to the non-SBFD symbol is the configured starting RB, and the starting position of the PUCCH resource corresponding to the SBFD symbol is (startingPRB+RB_offset)mod(UL_subband size∩active UL BWP size), where startingPRB is the starting physical resource block, RB_offset is the RB offset, UL_subband size is the uplink subband size, active UL BWP size is the size of the activated uplink bandwidth part, ∩ is the intersection operation, and mod is the remainder operation. The RB occupied by the PUCCH resource located in the SBFD symbol is 1 RB starting from the starting position, or n RBs, where n is the PRB number parameter (nrofPRBs).

[0561] In a possible design of this embodiment, the RB offset may be one RB offset or a list of RB offsets, where each RB offset corresponds to one PUCCH resource or one PUCCH resource set.

[0562] In a possible design of this embodiment, a set of configuration parameters (PUCCH-Config) is configured for the terminal device, and each PUCCH resource set in this set of configuration parameters includes N PUCCH resources, where N is twice the maximum number of PUCCH resources that can be configured in the current PUCCH resource set, wherein the first N / 2 PUCCH resources correspond to non-SBFD symbols, and the last N / 2 PUCCH resources correspond to SBFD symbols, or the first N / 2 PUCCH resources correspond to SBFD symbols, and the last N / 2 PUCCH resources correspond to non-SBFD symbols, and the first N / 2 PUCCH resources and the last N / 2 PUCCH resources share or do not share the time domain configuration.

[0563] In a possible design of this embodiment, a set of configuration parameters (PUCCH-Config) is configured for the terminal device, and the set of configuration parameters includes M PUCCH resource sets, where the first M / 2 PUCCH resource sets correspond to non-SBFD symbols, and the last M / 2 PUCCH resource sets correspond to SBFD symbols, or the first M / 2 PUCCH resource sets correspond to SBFD symbols, and the last M / 2 PUCCH resource sets correspond to non-SBFD symbols, and the first M / 2 PUCCH resource sets and the last M / 2 PUCCH resource sets share or do not share the time domain configuration.

[0564] Figure 18 shows a schematic diagram of configuring PUCCH resources according to an exemplary embodiment of the present application. In a time slot, the first seven symbols are SBFD symbols, and the eighth to fourteenth symbols are non-SBFD symbols. In one possible design of this embodiment, the first seven PUCCH resources in the PUCCH resource set are located at a first frequency domain location; the last seven PUCCH resources in the PUCCH resource set are located at a second frequency domain location.

[0565] In a possible design of this embodiment, the information configured separately in the above method also includes at least one of the following in addition to PUCCH resources: PUCCH power control configuration parameters (PUCCH-PowerControl), PUCCH spatial configuration parameters (PUCCH-SpatialRelationInfo), SR configuration parameters (SchedulingRequestResourceConfig), etc.; the shared configuration information in the above method also includes the time domain offset configuration (dl-DataToUL-ACK) from PDSCH to HARQ-ACK.

[0566] In a possible design of this embodiment, the receiving module 2930 is used to determine the target uplink channel resources used by the terminal device, and then receive the UCI sent by the terminal device on the target uplink channel resources, such as the HARQ-ACK codebook.

[0567] In a possible design of this embodiment, the terminal device does not expect that the configurations corresponding to at least two uplink channel resources are different; or, the terminal device expects that the configurations corresponding to at least two uplink channel resources are the same; or, the terminal device expects that at least two uplink channel resources both correspond to the first configuration; or, the terminal device expects that at least two uplink channel resources both correspond to the second configuration.

[0568] In a possible design of this embodiment, the terminal device does not expect to configure or indicate the target uplink channel resources through the resource configuration sending device, and the target uplink channel resources are in a time slot that includes both the first type of time domain resources and the second type of time domain resources.

[0569] The resource configuration sending device will try to configure in accordance with the terminal device's expectations, but it may not be 100% in accordance with the terminal device's expectations. In some cases, the resource configuration sending device may send configuration information in a manner that the terminal device does not expect. In this case, how the terminal device handles the unexpected configuration information is not limited by this application, and for example, it can be implemented independently by the terminal device.

[0570] In a possible design of this embodiment, the configurations corresponding to at least two uplink channel resources include a first configuration and / or a second configuration.

[0571] In a possible design of this embodiment, when the configurations corresponding to at least two uplink channel resources are different, the UCI corresponding to the at least two uplink channel resources is not multiplexed. In this case, the terminal device will construct two HARQ-ACK codebooks, HARQ-ACK codebook 1 corresponds to the first configuration, and HARQ-ACK codebook 2 corresponds to the second configuration.

[0572] This embodiment uses one sending module 2910, one determining module 2920, and one receiving module 2930 as an example.
