[0005] Electronic devices can communicate with wireless communication networks by wirelessly sending and receiving signals. Uplink L1 / L2 control signaling can be used to support data transmission on downlink or uplink transmission channels. In Long Term Evolution (LTE) or New Radio (NR) networks, uplink control information (UCI) can be transmitted via resources used for uplink L1 / L2 control on the physical uplink control channel (PUCCH). UCI includes hybrid automatic repeat request-acknowledgement (HARQ-ACK), channel state information (CSI) and scheduling request (SR). Summary of the invention

[0006] Aspects of the present invention provide an electronic device including a transceiver and a processing circuit and a method for wireless communication. The transceiver may receive configuration information for PUCCH resource configuration from a network in a wireless communication system. The configuration information may indicate a first interlace set including a first set of frequency domain physical resources. The processing circuit may determine resource allocation of PUCCH resources in the frequency domain based at least on the first interlace set. The transceiver may send UCI on the PUCCH resources.

[0007] In one embodiment, the configuration information further indicates a second interleaving set including a second set of frequency domain physical resources. The processing circuit can determine resource allocation of PUCCH resources in the frequency domain based on the first interleaving set and the second interleaving set. In one example, the configuration information further indicates a PUCCH format configuration of the PUCCH resources, and the PUCCH format configuration indicates the second interleaving set.

[0008] In one embodiment, the configuration information further indicates the number of one or more interleaving sets of PUCCH resources. The one or more interleaving sets include a first interleaving set. The processing circuit may determine resource allocation of the PUCCH resources in the frequency domain based on the one or more interleaving sets.

[0009] In one embodiment, the configuration information further indicates subband allocation information of at least one subband within the bandwidth of the PUCCH resource. The processing circuit may determine the resource allocation of the PUCCH resource in the frequency domain based at least on the first interleaving set and the subband allocation information. In one example, the processing circuit may determine the resource allocation of the PUCCH resource in the frequency domain as the intersection of the first set of frequency domain physical resources and at least one subband.

[0010] In one example, the configuration information further indicates a second interlace set including a second set of frequency domain physical resources.

The processing circuit may determine resource allocation of at least one candidate resource in the frequency domain based at least on the first interleaving set and the subband allocation information. The processing circuit may determine resource allocation of the PUCCH resource in the frequency domain from the at least one candidate resource. In one example, the processing circuit may determine the resource allocation in the frequency domain for each of the at least one candidate resource as the intersection of the first set of frequency domain physical resources and a corresponding resource in the at least one subband.

[0013] In one example, the configuration information further indicates a second interleaving set including a second set of frequency domain physical resources. The processing circuit can determine the resource allocation of each of the at least one candidate resource in the frequency domain as an intersection of the first and second sets of frequency domain physical resources and a corresponding resource in the at least one subband.

[0014] The configuration method of PUCCH resources proposed in the present invention can specify the maximum power spectral density (PSD) allowed in certain frequency bands to ensure limited interference between communication devices sharing the same frequency band. In order to meet the PSD requirement, the communication device can spread the transmission signal to a wider bandwidth through this staggered set allocation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 A block diagram of an exemplary communication system 100 according to an embodiment of the present invention is shown. The communication system 100 includes a network 101 and an electronic device 110 that receives a wireless communication service from the network 101. The electronic device 110 may be configured to receive configuration information 140 for PUCCH resource configuration from the network 101. The configuration information 140 indicates a first interleaving set of a first group of frequency-domain physical resources including PUCCH resources. The electronic device 110 may be configured to determine resource allocation of PUCCH resources in the frequency domain based at least on the first interleaving set. The configuration information 140 also indicates a second interleaving set including a second group of frequency-domain physical resources and subband allocation information of at least one subband within the bandwidth of the PUCCH resources, etc. In addition to the first interleaving set, the electronic device 110 may also determine resource allocation of PUCCH resources in the frequency domain based on the second interleaving set, the subband allocation information, etc.

[0028] In one example, the network 101 includes a fifth-generation (5G) radio access network (RAN) (or next generation (NG) RAN) and a 5G core network (5GC) using 5G mobile network technology. The base station 120 in the network 101 is a next generation Node B (gNB) specified in the 5G New Radio (NR) air interface standard developed by the 3rd Generation Partnership Project (3GPP).

[0029] The network 101 includes various base stations, such as base station 120, and core nodes interconnected using any suitable network technology (such as wired, wireless, cellular communication technology, local area network (LAN), wireless LAN (WLAN), fiber optic network, wide area network (WAN), peer-to-peer network, Internet, etc.). In some embodiments, the network 101 uses any suitable wireless communication technology, such as second generation (2G), third generation (3G) and fourth generation (4G) mobile network technology, 5G mobile network technology, global system for mobile communication (GSM), LTE, NR technology, etc. to provide wireless communication services to electronic devices (such as electronic device 110). In some examples, the network 101 adopts wireless communication technology developed by 3GPP. In one example, the base stations in the network 101 form one or more access networks, and the core nodes form one or more core networks. The access network can be a RAN, such as a 5GRAN or a NG RAN. The core network can be an evolved packet core (EPC), a 5GC, etc.

[0030] In various examples, base station 120 may be referred to as a Node B, an evolved Node B, a gNB, etc. Base station 120 includes hardware components and software components configured to enable wireless communications between base station 120 and electronic device 110. In addition, core nodes include hardware components and software components that form a backbone to manage and control services provided by network 101.

[0031] In some embodiments, high frequencies, also referred to as millimeter wave (mmWave) frequencies, are used as carrier frequencies in the communication system 100 to increase network capacity. In one example, the high frequency is higher than 6 GHz, such as between 24-84 GHz. In one example, a carrier frequency less than 6 GHz is referred to as a low frequency, such as between 600 MHz and less than 6 GHz. For example, frequency range 1 (FR1) includes frequencies below 7 GHz, and frequency range 2 (FR2) includes frequencies in the range of 24.25-52.6 GHz. Signals (or beams) with millimeter wave frequencies as carrier frequencies, referred to as high frequency (HF) signals, may experience greater propagation losses and may be sensitive to blocking. Therefore, for HF signals, the base station 120 and the electronic device 110 may perform beamforming transmission and / or reception to compensate for propagation losses.

[0032] In one embodiment, the electronic device 110 can be any suitable electronic device configured to determine resource allocation of PUCCH resources based on configuration information of the PUCCH resources (e.g., including a first interleaving set, a second interleaving set (optional), and subband allocation information (optional)). Resource allocation includes resource allocation in the frequency domain (e.g., resource blocks (RB)) and resource allocation in the time domain (e.g., symbols). In one example, the electronic device 110 is a terminal device (e.g., user equipment) for wireless communication, such as a mobile phone, a smart phone, a tablet computer, a laptop computer, a smart device, a wearable device, etc.

[0033] refer to Figure 1 , the electronic device 110 includes a transceiver 113, a processing circuit 117, and a memory 115, which are coupled together (e.g., using a bus architecture 111). The transceiver 113 can be configured to receive signals from the network 101 (e.g., the base station 120) and send signals to it. The signals can include high-frequency signals (e.g., FR2) and low-frequency signals (e.g., FR1). The signals can be sent via directional beams or beam pairs in beamforming transmission / reception.

[0034] refer to Figure 1 , the electronic device 110 may transmit (e.g., report) UCI ​​via PUCCH to support data transmission on a downlink or uplink transmission channel. UCI includes HARQ-ACK for a received downlink shared channel (DL-SCH) transmission block, CSI related to downlink channel conditions for downlink scheduling, and SR for uplink resources for uplink shared channel (UP-SCH) transmission. UCI may be sent by the transceiver 113 via PUCCH and may be received by the network 101.

[0035] UCI may be sent via PUCCH resources (e.g., resources specifically allocated for PUCCH transmission). For example, PUCCH resources may be frequency domain and time domain physical transmission resources, such as resources including multiple symbols and multiple RBs (e.g., physical resource blocks (PRBs)) on a resource grid (e.g., an orthogonal frequency division multiplex (OFDM) resource grid). In one example, the PUCCH resources may be configured for the electronic device 110 by the network 101 (e.g., the base station 120). For example, configuration may be performed via radio resource control (RRC) signaling, a medium access control (MAC) layer control element (CE), downlink control information, or a combination thereof.

[0036] The signal received from the network 101 (e.g., the base station 120) includes configuration information 140. The configuration information 140 may indicate frequency domain physical resource information and time domain resource information for configuring PUCCH resources. The frequency domain physical resource information includes a first interleaving set index of a first interleaving set (or a starting interleaving set), a starting RB index of a starting RB in the first interleaving set, a second interleaving set index of a second interleaving set, the number of one or more interleaving sets including the first interleaving set, and subband allocation information of at least one subband (e.g., within a bandwidth). The configuration information 140 may also indicate bandwidth information of a bandwidth, for example, information indicating a carrier and a BWP in a carrier. According to the configuration information 140, each of the bandwidth, the carrier, and the BWP may include multiple RBs. In an example, the first interleaving set and the second interleaving set are within a bandwidth or a carrier. The configuration information 140 may also indicate subband information of one or more subbands within a bandwidth. According to the configuration information 140, each subband may include multiple RBs within a bandwidth. In an example, the subband information may also be predefined in the specification.

[0037] The one or more interleaving sets optionally include a second interleaving set and an additional interleaving set. In one example, the one or more interleaving sets include the first interleaving set, and the number of the one or more interleaving sets is 1. In one example, the one or more interleaving sets include the first interleaving set and the second interleaving set, and the number of the one or more interleaving sets is 2. In one example, the one or more interleaving sets include the first interleaving set, the second interleaving set, and the additional interleaving set, so that the number of the one or more interleaving sets is greater than 2.

[0038] The time domain resource information includes symbols allocated for PUCCH resources as indicated based on a starting symbol (or first symbol) indication (eg, a first symbol index) and the number of symbols.

[0039] Figure 2 An example of a PUCCH resource 201 according to an embodiment of the present invention is shown. The PUCCH resource 201 includes frequency domain resources, such as PRBs (such as PRBs 4-11) and time domain resources, such as symbols (such as symbols 2-7). The PUCCH resource 201 may be configured based on a PUCCH resource configuration 220, a resource format configuration (e.g., a PUCCH format configuration) 230, and the like. The PUCCH resource 201 may be configured for the electronic device 110. The configuration information 140 may indicate a PUCCH format configuration 230 for the PUCCH resource configuration 220. In an example, the configuration information 140 including the PUCCH resource configuration 220 and / or the resource format configuration 230 may be sent from the network 101 to the electronic device 110 (e.g., via RRC signaling).

[0040] The PUCCH resource configuration 220 may indicate a PUCCH resource ID (e.g., PUCCH-RESOURCEID=#2) 221, a starting frequency-domain physical resource (e.g., a starting PRB in the frequency domain (e.g., STARTINGPRB=PRB#4)) 222, a resource format (e.g., PUCCH-FORMATX, where "X" includes a value indicating a specific format) 223, and / or other parameters. A resource format configuration 230 corresponding to the resource format 223 may indicate a starting symbol 231 (e.g., based on a starting symbol index (e.g., STARTINGSYMBOLINDEX=symbol#2)), the number of symbols (optional) 233, the number of frequency-domain physical resources (e.g., the number of PRBs (e.g., NROFPRBS=8)) 232 (optional), and / or other parameters. When the number of frequency-domain physical resources 232 is equal to 1, the number of frequency-domain physical resources 232 may be omitted from the resource format configuration 230. Similarly, when the number of symbols 233 is equal to 1, the number of symbols 233 may be omitted.

[0041] refer to Figure 2, a PUCCH resource 201 is shown in a resource grid (e.g., an OFDM resource grid) 210. The resource grid 210 includes a plurality of PRBs in the frequency domain, each PRB having an index (e.g., #0, #1, #2, etc.), and a plurality of symbols in the time domain, each symbol having an index (e.g., #0, #1, #2, etc.). The PUCCH resource 201 may be specified by a PUCCH resource configuration 220 and a resource format configuration 230. The PUCCH resource 201 may be located within a time slot 211, for example, the time slot 211 includes 14 symbols with indices from #0 to #13. For example, the PUCCH resource 201 has a PUCCH resource ID #2 in the frequency domain, includes PRBs #4-#11 (starting from PRB #4 indicated by 222 and including eight PRBs indicated by 232), and includes symbols #2-#7 (starting from symbol #2 indicated by 231 and including six symbols indicated by 233). As described above, PUCCH resources (eg, PUCCH resources 201 ) in the frequency domain and the time domain may be identified based on a PUCCH resource configuration (eg, PUCCH resource configuration 220 ).

[0042] In some examples, the PUCCH resource configuration 220 also indicates the frequency hopping within the time slot and the starting frequency domain physical resource after the frequency hopping (e.g., for the second hop). Figure 10-11 As shown, resource format 223 (e.g., PUCCH-format X) can be any suitable format, such as PUCCH-format 0 (e.g., X=0), PUCCH-format 1 (e.g., X=1), PUCCH-format 2 (e.g., X=2), PUCCH-format 3 (e.g., X=3), PUCCH-format 4 (e.g., X=4), PUCCH-format 2-r16, PUCCH-format 3-r16, etc.

[0043] In addition to Figure 2 In addition to configuring PUCCH resources using continuous RBs (e.g., PRB#4-#11) as shown, PUCCH resources can also be configured based on non-continuous RBs, such as RBs in an interleaving set structure (also called a block interleaving set structure or an interleaving set structure). In one example, such as in an unlicensed band, a frequency domain physical resource with a block interleaving set structure can be configured for PUCCH resources to meet the requirements of occupied channel bandwidth (OCB) and power spectral density, PSD level. Therefore, PUCCH resources (e.g., in an unlicensed band) can be configured with one or more interleaving sets.

[0044] An interlace set may be a basic unit of frequency domain resource allocation, including a group of frequency domain physical resources, for example, within a specific bandwidth (eg, a carrier or a BWP in a carrier). The set of frequency domain physical resources may be equidistantly distributed in the frequency domain within the specific bandwidth. Figure 3 An example of M (e.g., M=10) interleaving sets #0-#9 according to one embodiment of the present invention is shown. A resource grid (e.g., OFDM resource grid) 310 includes a plurality of symbols (e.g., symbols #0-#13) in the time domain and a plurality of RBs (e.g., RB#0-#105) in the frequency domain. The subcarrier spacing (SCS) can be any suitable frequency, such as 15khz, 30khz, 60khz, 120khz, 240khz, etc. In one example, the SCS is 15khz.

[0045] M interlace sets #0-#9 may be specified or defined based on resource grid 310. In one example, a bandwidth (e.g., 20 MHz) includes 106 RBs (e.g., RBs #0-105), and the M interlace sets are within the bandwidth. Each interlace set of the M interlace sets #0-#9 (e.g., interlace set #m with index m) includes N RBs. N may be any suitable number, such as 10 or 11. Reference Figure 3 , when m is 0, 1, 2, 3, 4, or 5, interlace set #m includes 11 RBs: RB#(0+m), RB#(M+m), RB#(2×M+m), RB#(3×M+m), RB#(4×M+m), RB#(5×M+m), RB#(6×M+m), RB#(7×M+m), RB#(8×M+m), RB#(9×M+m), and RB#(10×M+m), where m=10. In one example, interlace set #0 (m=0; in Figure 3 RB#0, RB#10, RB#20…RB#100, interleaving set #1 includes 11 RBs: RB#1, RB#11, RB#21…RB#101. When m is 6, 7, 8, and 9, interleaving set #m includes 10 RBs: RB(0+m), RB(m+m), RB(2×m+m), RB(3×m+m), RB(4×m+m), RB(5×m+m), RB(6×m+m), RB(7×m+m), RB(8×m+m), and (RB+m). For example, interleaving set #9 includes 10 RBs: RB#9, RB#19, RB#29…RB#99. Figure 3 Line 351 in lists the index m of the corresponding interleave set #m.

[0046] The frequency domain physical resource sets in interlace set #m are equidistantly distributed in the frequency domain within a specific bandwidth, and the frequency difference (or frequency interval) between two adjacent RBs in interlace set #m may correspond to the frequency difference of m RBs (eg, 10 RBs).

[0047] Return to reference Figure 1 , the processing circuit 117 may be configured to determine the resource allocation of the PUCCH resources based on the configuration information 140 for configuring the PUCCH resources. The processing circuit 117 may be configured to determine the resource allocation of the PUCCH resources in the frequency domain based on the configuration information 140. As described above, the PUCCH resources may be configured based on one or more interleaving sets. The configuration information 140 may indicate information of one or more interleaving sets, for example, a first interleaving set (or a starting interleaving set) of a first group of frequency-domain physical resources including the PUCCH resources, subband allocation information of at least one subband within the bandwidth of the PUCCH resources, a second interleaving set of a second group of frequency-domain physical resources including the PUCCH resources, and the like. According to various aspects of the present invention, the processing circuit 117 may be configured to determine the resource allocation of the PUCCH resources in the frequency domain based at least on the first interleaving set. In one embodiment, the processing circuit 117 may determine the resource allocation of the PUCCH resources in the frequency domain based on the first interleaving set and the second interleaving set. In another embodiment, the processing circuit 117 may determine the resource allocation of the PUCCH resources in the frequency domain based at least on the first interleaving set and the subband allocation information. In one example, the processing circuit 117 may be configured to determine that the PUCCH resources include a subset of the first group of frequency-domain physical resources within at least one subband. The subset of the first group of frequency-domain physical resources may be the intersection of the first group of frequency-domain physical resources and at least one subband. In one example, the processing circuit may determine the resource allocation of the PUCCH resources in the frequency domain as the intersection of the first group of frequency-domain physical resources and at least one subband. In one embodiment, the processing circuit 117 may be configured to determine that the PUCCH resources include a combined subset of the first and second groups of frequency-domain physical resources within at least one subband. The combined subset may be the intersection of the first and second groups of frequency-domain physical resources and at least one subband. In one example, the processing circuit may be configured to determine the resource allocation of the PUCCH resources in the frequency domain as the intersection of the first and second groups of frequency-domain physical resources and at least one subband.

[0048] In one embodiment, the processing circuit 117 may be configured to determine the frequency domain resource allocation of at least one candidate resource based at least on the first interleaving set and the subband allocation information. The processing circuit 117 may also be configured to determine the resource allocation of the PUCCH resource in the frequency domain from the at least one candidate resource. In one example, the processing circuit 117 may be configured to determine that at least one candidate resource including a subset of the first group of frequency domain physical resources (the frequency domain physical resource is within at least one subband of the subset of the first group of frequency domain physical resources) may be the intersection of the first group of frequency domain physical resources and at least one subband. In one example, the processing circuit may be configured to determine the frequency domain resource allocation of each of the at least one candidate resource as the intersection of the first group of frequency domain physical resources and the corresponding resource in at least one subband. In another example, the processing circuit 117 may be configured to determine that at least one candidate resource including the first group and the second group of frequency domain physical resources (the frequency domain physical resource is within at least one subband of the subset of the first group of frequency domain physical resources) may be the intersection of the first group and the second group of frequency domain physical resources and at least one subband. In one example, the processing circuit may be configured to determine resource allocation in the frequency domain for each of the at least one candidate resource as an intersection of the first and second groups of frequency domain physical resources and corresponding resources in at least one subband.

[0049] As described above, at least one subband may be within a bandwidth, and the bandwidth may be a carrier or a BWP in a carrier.

[0050] As described above, the configuration information 140 may indicate time domain resource information, for example, a symbol (eg, a starting symbol (or first symbol) indication (eg, a first symbol index) and the number of symbols allocated for the PUCCH resource. Figure 2 As described above, the processing circuit 117 may be configured to determine resource allocation of the PUCCH resources in the time domain based on the time domain resource information in the configuration information 140 .

[0051] The processing circuit 117 may be implemented using various technologies, such as an integrated circuit / one or more processors executing software instructions, etc.

[0052] The memory 115 may be any suitable device for storing data and instructions to control the operation of the electronic device 110. The memory 115 may store information (e.g., configuration information (e.g., configuration information 140), PUCCH resource configuration (e.g., PUCCH resource configuration 220)), PUCCH resource format configuration (e.g., PUCCH resource format configuration 230), block interleaving set structure (e.g., Figure 3 The memory 115 may store UCI to be sent from the electronic device 110 to the network 101.

[0053] In one embodiment, the memory 115 may be a non-volatile memory, such as a read-only memory, a flash memory, a magnetic computer storage device, a hard disk drive, a solid-state drive, a floppy disk, a magnetic tape, an optical disk, etc. In one embodiment, the memory 115 may be a random access memory (RAM). In one embodiment, the memory 115 includes a non-volatile memory and a volatile memory.

[0054] The network 101 includes a processing circuit 125 that can configure PUCCH resources for the electronic device 110. The processing circuit 125 can be located at any suitable location within the network 101. In one example, the processing circuit 125 is located in the base station 120. The processing circuit 125 can determine configuration information 140 (e.g., a first interlace set for PUCCH resources, subband allocation information, a second interlace set for PUCCH resources, etc.). The configuration information 140 can be sent from the network 101 (e.g., the base station 120) to the electronic device 110. The UCI can be sent from the electronic device 110 via the PUCCH and can be received by the network 101.

[0055] As described above, resource allocation of PUCCH resources in the frequency domain can be determined based on at least the first interleaving set in the configuration information 140 of the PUCCH resources. According to various aspects of the present invention, PUCCH resources can be configured based on the first interleaving set (or the starting interleaving set). In one example, in addition to the first interleaving set, the configuration information 140 also indicates a second interleaving set, and resource allocation of PUCCH resources in the frequency domain can be determined based on the first interleaving set and the second interleaving set. In one example, the configuration information 140 may indicate the number of one or more interleaving sets of PUCCH resources, wherein the one or more interleaving sets include the first interleaving set. Therefore, resource allocation of PUCCH resources in the frequency domain can be determined based on one or more interleaving sets.

[0056] Figure 4An example of a PUCCH resource configured based on a first interleaving set according to an embodiment of the present invention is shown. As described above, a resource grid (e.g., an OFDM resource grid) 310 includes a plurality of symbols in the time domain (e.g., symbols 0-13) and a plurality of RBs in the frequency domain (e.g., RB-0-105). The PUCCH resource may be configured based on a PUCCH resource configuration 420 included in the configuration information 140. The PUCCH resource configuration 420 may indicate a PUCCH resource ID (e.g., #2) 421, a starting frequency domain physical resource (e.g., a starting interleaving set or a first interleaving set (e.g., interleaving set #4) 422 in the frequency domain), a resource format (e.g., PUCCH-FORMATX, where "X" includes a value indicating a specific format) 423, and / or other parameters. The resource format configuration (e.g., PUCCH format configuration) 430 corresponding to the resource format 423 in the configuration information 140 may indicate a starting symbol (e.g., a starting symbol index or symbol #2) 431, a number of symbols (e.g., 6 symbols) 433, a second interleaving set (e.g., based on a second interleaving set index) 432 (e.g., interleaving set #7), and / or other parameters. When the second interleaving set is not available or does not exist, the second interleaving set 432 may be omitted from the resource format configuration 430. Similarly, when the number of symbols 433 is equal to 1, the number of symbols 433 may be omitted. The configuration information 140 may indicate a PUCCH format configuration 430 for the PUCCH resource configuration 420, and the PUCCH format configuration 430 may indicate the second interleaving set 432.

[0057] As mentioned above Figure 3 As described, the interleaving set structure includes M (e.g., M=10) interleaving sets #0-#9. Based on the first interleaving set (e.g., the first interleaving set index) indicated by the PUCCH resource configuration 420 and the second interleaving set (e.g., the second interleaving set index) 432 indicated by the resource format configuration 430, the PUCCH resources include the interleaving set 4 (or the first interleaving set) indicated by 422 and the interleaving set 7 (or the second interleaving set) indicated by 432 in the frequency domain. Based on the resource format configuration 430 (e.g., 431 and 433), the PUCCH resources include symbols #2-#7 in the time domain. Reference Figure 4 , the PUCCH resources are highlighted by the grey area in the resource grid 310 .

[0058] The frequency domain resource configuration of PUCCH resources can be summarized as follows. Interlace sets #4 and #7 indicated by the first interlace set and the second interlace set (in Figure 4 Alternatively, the PUCCH resources configured by interlace sets 4 and 7 may be specified by the RBs in interlace sets 4 and 7. For example, interlace set 4 corresponds to interlace set m, where m is 4. Figure 3As described above, interlace set 4 (i.e., m=4) includes 11 RBs: RB#4, RB#14, RB#24, RB#34, RB#44, RB#54, RB#64, RB#74, RB#84, RB#94, and RB#104. Interlace set #7 corresponds to interlace set #m, where m is 7. As described above with reference to Figure 3 As described, interlace set 7 (ie, m=7) includes 10 RBs: RB#7, RB#17, RB#27, RB#37, RB#47, RB#57, RB#67, RB#77, RB#87, and RB#97.

[0059] Figure 5 An example of a PUCCH resource configured based on a first interleaving set according to an embodiment of the present invention is shown. The resource grid 310 is described above, so a detailed description is omitted for brevity. The PUCCH resource may be configured based on a PUCCH resource configuration 520 included in the configuration information 140. The PUCCH resource configuration 520 may indicate a PUCCH resource ID (e.g., #2) 521, a starting frequency domain physical resource (e.g., a starting interleaving set or a first interleaving set (e.g., interleaving set #4) in the frequency domain) 522, a resource format (e.g., PUCCH-FORMATX, where "X" includes a value indicating a specific format) 523, and / or other parameters. The resource format configuration (e.g., PUCCH format configuration) 530 corresponding to the resource format 523 in the configuration information 140 may indicate a starting symbol (e.g., a starting symbol index or symbol #2) 431, the number of symbols (e.g., 6 symbols) 533, the number of one or more interleaving sets configured for the PUCCH resource 532 (e.g., NROFINTERLACES=3), and / or other parameters. When the number 532 of one or more interleaving sets is 1, the number 532 of one or more interleaving sets may be omitted from the resource format configuration 530. Similarly, when the number of symbols 533 is equal to 1, the number of symbols 533 may be omitted. The configuration information 140 may indicate a PUCCH format configuration 530 for the PUCCH resource configuration 520, and the PUCCH format configuration 530 may indicate the number 532 of one or more interleaving sets configured for the PUCCH resource.

[0060] Based on the PUCCH resource configuration 520 (e.g., 522) and the resource format configuration 530 (e.g., 532) included in the configuration information 140, the processing circuit 117 may determine that the PUCCH resource includes interlace sets #4-#6 in the frequency domain. Based on the resource format configuration 430 (e.g., 531 and 533), the PUCCH resource includes symbols #2-#7. Figure 5 , the PUCCH resources are highlighted by the grey area in the resource grid 310 .

[0061] The frequency domain resource configuration of PUCCH resources can be summarized as follows. Interlace sets K1, K1+1...K1+K-1 are configured for PUCCH resources, where K may refer to the number of one or more interlace sets, and K1 may refer to the first interlace set index (e.g., 522). Figure 5 , K is 3, K1 is 4, so PUCCH resource configuration interlace sets #4, #5 and #6 (in Figure 5 highlighted in grey in the figure).

[0062] The PUCCH resources configured by interlace sets 4 to 6 can be specified using RB indexes (e.g., #0-#105). The RB index can be described using formula (1):

[0063] RB Index = RB start +k+n×M(1)

[0064] Among them, RB start refers to the starting frequency domain physical resource, such as RB#4. k corresponds to 0, 1…(K-1), so for interleaving sets #4-#6 (e.g., K=3), K is 0, 1, and 2, respectively. M is the number of interleaving sets in the interleaving set structure (e.g., the total number of interleaving sets), and Figure 5 M may also refer to the frequency difference (or spacing) between consecutive RBs in each interlace set #0-#9. As described above, for a corresponding RB of one of interlace sets #4-#6, n is 0, 1, 2 ... N-1, where N is the number of RBs in the interlace set. N may be 10 or 11. As described above, for interlace sets #0-#5, N is 11, and for interlace sets #6-#9, N is 10.

[0065] Based on the above description, for interleaving sets #4-#6, RB startis 4, K is 3, M is 10, and N is 11. In addition, for the RBs in the corresponding interlace set, n is 0, 1, 2...10. Therefore, for interlace set #4, k is 0, so based on equation (1), the RB indices for n being 0, 1, 2...10 are 4, 14, 24...104. Therefore, interlace set #4 includes 11 RBs: RB#4, RB#14, RB#24, RB#34, RB#44, RB#54, RB#64, RB#74, RB#84, RB#94, and RB#104. For interlace set #5, k is 1. Similarly, based on equation (1), the RB indices for n being 0, 1, 2...10 are 5, 15, 25...105. Therefore, interlace set 5 includes 11 RBs: RB#5, RB#15, RB#25, RB#35, RB#45, RB#55, RB#65, RB#75, RB#85, RB#95, and RB#105. For interlace set #6, k is 2, so based on equation (1), the RB indexes for n being 0, 1, 2, ... 10 are 6, 16, 26, ... 106. Therefore, interlace set 6 includes 11 RBs: RB#6, RB#16, RB#26, ... RB#106.

[0066] As described above, resource allocation of PUCCH resources in the frequency domain may be determined based on at least the first interleaving set in the configuration information 140 of the PUCCH resources. In one example, the configuration information 140 further indicates subband allocation information for at least one subband of the PUCCH resources. Therefore, resource allocation of PUCCH resources in the frequency domain may be determined based on at least the first interleaving set and the subband allocation information.

[0067] The bandwidth can be divided into one or more subbands. Each subband includes a subset (available) of the frequency domain physical resources (e.g., available RBs) of the bandwidth. The configuration information 140 may indicate subband information of one or more subbands within the bandwidth. According to the configuration information 140, each subband includes a subset of RBs of the bandwidth. In one example, the subband information may also be predefined in the specification. If there are multiple subbands within the bandwidth, the multiple subbands may be orthogonal, for example, there is no overlap between adjacent subbands. The multiple subbands may be non-orthogonal, for example, there is overlap between adjacent subbands. The bandwidth may be a carrier or a BWP in a carrier. Reference Figure 6 and 7 , such as a bandwidth of carrier 601, can be divided into subbands 610-613 (e.g., referred to as subbands 0-3 in carrier 601). In one example, subbands #0-#3 are orthogonal. Figure 7 , the carrier 601 includes a BWP 701, and the BWP 701 may be divided into subbands 611-613 (eg, referred to as subbands #0-#2 in the BWP 701). Generally, one carrier includes one or more BWPs.

[0068] The PUCCH resource configuration includes subband allocation information to indicate to the electronic device 110 at least one subband within the bandwidth, and the at least one subband may be configured with a frequency domain physical resource configuration. Figure 6 , the PUCCH resource configuration 620 included in the configuration information 140 may indicate subband allocation information 624 (eg, using a subband index in the bandwidth), such as SUBBANDALLOCATION=SUBBAND#1.

[0069] The PUCCH resource configuration 620 included in the configuration information 140 may indicate the starting frequency domain physical resource and resource format. Figure 4 As described, the PUCCH resource configuration 620 may indicate a PUCCH resource ID (e.g., #2) 621, a starting frequency domain physical resource (e.g., a starting interleaving set or a first interleaving set in the frequency domain (such as interleaving set #0)) 622, a resource format (e.g., PUCCH-FORMATX, where "X" includes a value indicating a specific format) 623 and / or other parameters.

[0070] In addition, the resource format configuration (e.g., PUCCH format configuration) 630 corresponding to the indicated resource format 623 in the configuration information 140 includes multiple frequency-domain physical resources. When there are multiple frequency-domain physical resources, the frequency-domain physical resources within the bandwidth can be indicated based on the starting frequency-domain physical resource (e.g., 622) and the number of frequency-domain physical resources. In an example, the number of frequency-domain physical resources is 1 and can therefore be omitted.

[0071] The frequency domain physical resource may be represented by one or more interleaving sets including the first interleaving set. When the one or more interleaving sets include the second interleaving set, the resource format configuration 630 included in the configuration information 140 may use the following example: Figure 6 The second interleaving set index (e.g., interleaving set 1) shown indicates the second interleaving set 632. When the second interleaving set is not available or does not exist, the second interleaving set 632 can be omitted from the resource format configuration 630. Alternatively, the resource format configuration 630 can indicate the number of one or more interleaving sets configured for the PUCCH resource by replacing the second interleaving set 632 with the number of one or more interleaving sets (e.g., NROFINTERLACES, such as 2). The configuration information 140 can indicate a PUCCH format configuration 630 for the PUCCH resource configuration 620, and the PUCCH format configuration 630 can indicate the second interleaving set 632.

[0072] The resource format configuration 630 may indicate a starting symbol (eg, a starting symbol index or symbol #2) 631, the number of symbols (eg, 6 symbols) 633, and / or other parameters. Similarly, when the number of symbols 633 is equal to 1, the number of symbols 633 may be omitted.

[0073] The frequency domain physical resource configured for the PUCCH resource may be determined as a combination or intersection of at least one subband indicated by 624 and the frequency domain physical resource indicated by the PUCCH resource configuration 620 (eg, indicated by 622, 632 (if applicable)). Figure 6 , the frequency-domain physical resources indicated by the PUCCH resource configuration 620 include a first interlace set (e.g., interlace set 0 indicated by 622) and a second interlace set (e.g., interlace set 1 indicated by 632), and thus the frequency-domain physical resources include RB 640. On the other hand, at least one subband indicated by the subband allocation information 624 in the PUCCH resource configuration 620 includes subband 611 (or subband 1 in carrier 601). Subbands 610, 612, and 613 are not included in at least one subband. Therefore, the intersection or combination of at least one subband (e.g., subband 611) and the frequency-domain physical resources 640 includes RBs 640(1)-640(5). Therefore, it can be determined that RBs 640(1)-640(5) are configured for PUCCH resources. In one example, it can be determined that symbols #2-#7 are configured for PUCCH resources based on 631 and 633. Subsequently, the electronic device 110 can send UCI on the PUCCH resources.

[0074] refer to Figure 7 , carrier 601 includes BWP 701, and BWP 701 may be divided into subbands 611-613. Subbands 611-613 may be referred to as subbands #0-#2 in BWP 701, respectively. Figure 7 In addition to the BWP 701 in which the subband allocation information may refer to one or more subband indices in the BWP 701, it may be related to Figure 6 PUCCH resources are configured similarly to what is described in .

[0075] The PUCCH resource configuration 720 included in the configuration information 140 may indicate subband allocation information 724, for example, using a subband index in the BWP 701 (such as SUBBANDALLOCATION=SUBBAND#0 in the BWP 701). The PUCCH resource configuration 720 may indicate a PUCCH resource ID (e.g., #2) 721, a first interleaving set in the frequency domain (e.g., interleaving set #0) 722, a resource format (e.g., PUCCH-FORMATX, where "X" includes a value indicating a specific format) 723, and / or other parameters. In the resource format configuration (e.g., PUCCH format configuration) 730 corresponding to the indicated resource format 723 included in the configuration information 140, a second interleaving set 732 (e.g., interleaving set #1) is indicated. When the second interleaving set does not exist, the second interleaving set 732 may be omitted from the resource configuration 730. The resource format configuration 730 may indicate a starting symbol (e.g., a starting symbol index or symbol #2) 731, a number of symbols (e.g., 6 symbols) 733, and / or other parameters. Similarly, when the number of symbols 733 is 1, the number of symbols 733 may be omitted. The configuration information 140 indicates a PUCCH format configuration 730 for the PUCCH resource configuration 720, and the PUCCH format configuration 730 may indicate a second interleaving set 732.

[0076] refer to Figure 7 , the frequency domain physical resources indicated by the PUCCH resource configuration 720 include a first interlace set (eg, interlace set 0) and a second interlace set (eg, interlace set 1), so as described above with reference Figure 6 The frequency domain physical resources include RB 640. On the other hand, at least one subband indicated by the subband allocation information 724 in the PUCCH resource configuration 720 includes subband 611 (referred to as subband 0 in BWP 701). Subbands 612-613 in BWP 701 are not included in the at least one subband. Therefore, the intersection or combination of at least one subband (e.g., subband 611) and the frequency domain physical resources 640 includes RB 640(1)-640(5). Therefore, it can be determined that RB 640(1)-640(5) is configured for PUCCH resources. In one example, it can be determined based on 731 and 733 that symbols #2-#7 are configured for PUCCH resources. Subsequently, the electronic device 110 can send UCI on the PUCCH resources.

[0077] As described above, the configuration information 140 may indicate a first interlace set and subband allocation information for at least one subband within the bandwidth of the PUCCH resource. According to aspects of the present invention, at least one frequency domain candidate resource (also referred to as a frequency domain candidate resource or at least one candidate resource) may be within at least one subband. Resource allocation for at least one candidate resource in the frequency domain may be determined based at least on the first interlace set and the subband allocation information. Resource allocation for the PUCCH resource in the frequency domain may be determined based on the determined at least one candidate resource. As described above, the bandwidth may be a carrier or a BWP in a carrier.

[0078] As described above, the first interleaving set may include a first set of frequency domain physical resources. It may be determined that the at least one candidate resource includes a subset of the first set of frequency domain physical resources located within the at least one subband, wherein the subset of the first set of frequency domain physical resources may be a combination or intersection of the first set of frequency domain physical resources and the subband. In one example, the resource allocation of each of the at least one candidate resource in the frequency domain is determined as the intersection of the first set of frequency domain physical resources and a corresponding subband in the at least one subband.

[0079] In one embodiment, the configuration information 140 further indicates a second interleaved set including a second set of frequency domain physical resources. Therefore, it can be determined that the at least one candidate resource includes a combined subset of the first set and the second set of frequency domain physical resources located in the at least one subband, wherein the combined subset may be an intersection of the first set and the second set of frequency domain physical resources and the at least one subband. In one example, the resource allocation of each of the at least one candidate resource in the frequency domain is determined as an intersection of the first and second sets of frequency domain physical resources and a corresponding subband in the at least one subband.

[0080] At least one candidate resource may be configured. In one example, one of the at least one candidate resource may be determined or selected as a PUCCH resource, and the electronic device 110 may send UCI on one of the at least one determined or selected candidate resources. In one example, multiple of the at least one candidate resource may be determined or selected as PUCCH resources, and the electronic device 110 may send UCI on each of the multiple resources determined in the at least one candidate resource. In one example, if one of the at least one candidate resource is available, the electronic device 110 may send UCI on one of the at least one candidate resource. In one example, the electronic device 110 may send UCI on each available resource in the at least one candidate resource.

[0081] Figure 8An example of at least one candidate resource according to an embodiment of the present invention is shown. As described above, the bandwidth is a carrier 601 including subbands 610-613 (or subbands 0-3 in carrier 601). At least one candidate resource may be configured for a PUCCH resource (e.g., #2) based on a PUCCH resource configuration 820. The PUCCH resource configuration 820 included in the configuration information 140 may indicate subband allocation information 824 (e.g., using a subband index in carrier 601, such as SUBBANDALLOCATION=SUBBAND#1 and SUBBAND#2). The PUCCH resource configuration 820 may indicate a PUCCH resource ID (e.g., #2) 821, a first interleaving set in the frequency domain (e.g., interleaving set #0) 822, a resource format (e.g., a PUCCH format configuration) (e.g., PUCCH-FORMATX, where "X" includes a value indicating a specific format) 823 and / or other parameters. In the resource format configuration 830 included in the configuration information 140 corresponding to the indicated resource format 823, a second interleaving set 832 (e.g., interleaving set #1) is indicated. When the second interleaving set does not exist, the second interleaving set 832 can be omitted from the resource configuration 830. The resource format configuration 830 can indicate a starting symbol (e.g., a starting symbol index or symbol #2) 831, a number of symbols (e.g., 6 symbols) 833, and / or other parameters. Similarly, when the number of symbols 833 is 1, the number of symbols 833 can be omitted. In addition, if at least one subband is located within the BWP, the above description can be appropriately adjusted. The at least one subband may include any appropriate number of subbands, such as 1, 2, etc. The number of interleaving sets configured in the PUCCH resource configuration may be 1, 2, etc. In one example, the number of interleaving sets is 1 (e.g., a first interleaving set) or 2 (e.g., a first interleaving set and a second interleaving set). The configuration information 140 may indicate a PUCCH format configuration 830 for the PUCCH resource configuration 820 , and the PUCCH format configuration 830 may indicate a second interlace set 832 .

[0082] In one example, the first candidate resource in the frequency domain is the intersection of the RBs in the first interlace set and the second interlace set and the RBs in subband 611 (e.g., RB 640), so the first candidate resource in the frequency domain includes RBs 640(1)-640(5). The second candidate resource in the frequency domain is the intersection of the RBs in the first interlace set and the second interlace set and the RBs in subband 612 (e.g., RB 640), so the second candidate resource in the frequency domain includes RBs 640(6)-640(10).

[0083] Fig. 9An example of RB set configuration (also referred to as intra-cell guard-band configuration) according to an embodiment of the present invention is shown. Bandwidth (e.g., carrier 901, BWP 901 in carrier 901) may be provided without or with any appropriate number of intra-cell (also referred to as intra-carrier) guard bands by RRC configuration, default configuration, etc. (e.g., for operations for shared spectrum channel access). The number of intra-cell guard bands in the bandwidth may be 0, 1, 2, etc. The intra-cell guard band may be divided into a plurality of RB sets based on the RB set configuration. Each of the plurality of RB sets includes a subset of (available) RBs of the bandwidth. The intra-cell guard band includes RBs, such as common RBs (CRBs), and therefore, the intra-cell guard band may be defined by a starting CRB and the size of the intra-cell guard band specified by a plurality of CRBs in the intra-cell guard band. The number of CRBs may be any suitable non-negative integer, such as 0, 1, 2, etc. The size of the intra-cell guard band or the number of CRBs may be zero, and therefore no intra-cell guard band is configured. In another example, if no RB set configuration (also called intra-cell guard band configuration) is provided for a bandwidth, one RB set may still be defined within the bandwidth, where the RB set may include all (available) RBs of the bandwidth.

[0084] One or more RB sets in a bandwidth are determined (eg, by electronic device 110 ) according to an intra-cell guard band configuration of the bandwidth. As described above, the bandwidth may be carrier 901 or BWP 902 in carrier 901 .

[0085] refer to Fig. 9 , carrier 901 can be divided into RB groups 910-913 by intra-cell guard bands 925-927. Carrier 901 also includes inter-cell (also called inter-carrier) guard bands 921-922. In one example, RB groups 910-913 are located between inter-cell guard bands 921-922. One of the inter-cell guard bands 921-922 can separate carrier 901 from another carrier. For RB sets 910-913, the RB set indexes within carrier 901 are 0, 1, 2, and 3, respectively.

[0086] The BWP 902 may be divided into RB groups 911-913 by intra-cell guard bands 926-927. For the RB sets 911-913, the RB set indexes in the BWP 902 may be 0, 1, and 2, respectively. In one example, the RB groups 911-913 are located between the inter-cell guard band 922 and the intra-cell guard band 925. Generally, one carrier may be configured with one or more BWPs. When a carrier includes multiple BWPs, the RB set in one of the multiple BWPs may be located between two intra-cell guard bands in the carrier.

[0087] Various PUCCH resource configurations (e.g., PUCCH resource configurations 220, 420, 520, 620, 720, and 820) including various parameters are described above. In some embodiments, the PUCCH resource includes parameters, such as PUCCH ResourceId (e.g., Figure 2 221) and the PUCCH resource index provided by the resource format (eg, Figure 2 223) in the PUCCH format resource format configuration (for example, Figure 2 PUCCH-FORMATX configuration 230).

[0088] In some examples, if the UE (e.g., electronic device 110) does not configure an interlace set and therefore useInterlacePUCCH-PUSCH is not provided to the UE in BWP-UplinkDedicated, the PUCCH resource also includes parameters, such as the index of the first PRB before or without frequency hopping, for example, Figure 2 The starting PRB 222 in the , the index of the first PRB after frequency hopping by secondHopPRB, and the indication of frequency hopping (eg, intra-slot frequency hopping) by intraSlotFrequency-Hopping.

[0089] In some examples, if the UE (e.g., electronic device 110) is configured with an interlace set and therefore useInterlacePUCCH-PUSCH is provided to the UE in BWP-UplinkDedicated, the PUCCH resource also includes parameters, such as the index of the first interlace set of interlace set 0 (e.g., Figure 4 The RB set may correspond to a subband, and the index of the RB set may correspond to a subband index (eg, 724).

[0090] If useInterlacePUCCH-PUSCH is provided to the UE (eg, the electronic device 110) in BWP-UplinkDedicated, the UE may use the active uplink (UL) BWP (eg, Figure 7 BWP 701 in PUCCH transmission) available RBs (e.g., Figure 7 RB 640(1)-640(5)) in the RB 640(1)-640(5)) is determined as the first RE corresponding to the interlace set index provided by interlace set 0 (eg, Figure 7640) and (if provided) interlace set 1 (e.g., the second interlace set or interlace set #1 732) and the second RB (e.g., Figure 7 The above intersection may be generated in a first interlace set (eg, indicated by interlace set 0). RBs. It can be 10 or 11. If a second interleaving set is provided (e.g., indicated by interleaving set 1), the intersection can be generated in the second interleaving set RBs. It can be 10 or 11.

[0091] As described above, the PUCCH resource includes a resource format configuration (e.g., PUCCH-FORMATX configuration 230, 430, 530, 630, 730, or 830) of a PUCCH format provided by a resource format (e.g., PUCCH-FORMATX in 223, 423, 523, 623, 723, or 823). Any suitable PUCCH format may be used. Figure 10-11 Examples of PUCCH formats (or resource formats) 1010-1016 according to an embodiment of the present invention are shown. If the resource format indicates PUCCH format 1010 or PUCCH-format0 (for example, X=0 in PUCCH-FORMATX), the PUCCH format configured for the PUCCH resource is PUCCH-format0. Therefore, the PUCCH resource includes the index of the initial cyclic shift provided by initialCyclicShift, the number of symbols of PUCCH transmission provided by nrofSymbols, and the first symbol of PUCCH transmission provided by startingSymbolndex. The index of the initial cyclic shift (for example, initialCyclicShift) can be any integer in the range of 0 to 11, the number of symbols of PUCCH transmission (for example, nrofSymbols) can be 1 or 2, and the first symbol of the PUCCH shift (for example, startingSymbolIndex) can be any integer in the range of 0 to 13.

[0092] If the resource format indicates PUCCH format 1011 or PUCCH-format1 (e.g., X=1 in PUCCH-FORMATX), the PUCCH format configured for the PUCCH resource is PUCCH-format1. Therefore, the PUCCH resource includes an index for the initial cyclic shift provided by initialCyclicShift, the number of symbols for PUCCH transmission provided by nrofSymbols, the first symbol for PUCCH transmission provided by startingsymbolndex, and an index of an orthogonal cover code (OCC) provided by timeDomainOCC. The index of the initial cyclic shift (e.g., initialCyclicShift) can be any integer in the range of 0 to 11, the number of symbols for PUCCH transmission (e.g., nrofSymbols) can be any integer in the range of 4 to 14, the first symbol of PUCCH transmission (e.g., startingSymbolIndex) can be any integer in the range of 0 to 10, and the index of the OCC (e.g., timeDomainOCC) can be any integer in the range of 0 to 6.

[0093] If the resource format indicates PUCCH format 1012 or PUCCH-format 2 (e.g., X=2 in PUCCH-FORMATX), the PUCCH format configured for the PUCCH resource is PUCCH-format 2. Therefore, the PUCCH resource includes the number of PRBs provided by nrofPRBs, the number of symbols of PUCCH transmission provided by nrofSymbols, and the first symbol of PUCCH transmission provided by startingSymbolIndex. The number of PRBs (e.g., nrofPRBs) can be any integer in the range of 1 to 16, the number of symbols of PUCCH transmission (e.g., NROFSYMBOL) can be 1 or 2, and the first symbol of PUCCH transmission (e.g., startingSymbolIndex) can be any integer in the range of 0 to 13.

[0094] If the resource format indicates PUCCH format 1013 or PUCCH-format 3 (e.g., X=3 in PUCCH-FORMATX), the PUCCH format configured for the PUCCH resource is PUCCH-format 3. Therefore, the PUCCH resource includes the number of PRBs provided by nrofPRBs, the number of symbols of PUCCH transmission provided by nrofSymbols, and the first symbol of PUCCH transmission provided by startingSymbolIndex. The number of PRBs (e.g., nrofPRBs) can be any integer in the range of 1 to 16, the number of symbols of PUCCH transmission (e.g., nrofSymbols) can be any integer in the range of 4 to 14, and the first symbol of PUCCH transmission (e.g., startingSymbolIndex) can be any integer in the range of 0 to 10.

[0095] If the resource format indicates PUCCH format 1014 or PUCCH-format 4 (e.g., X=4 in PUCCH-FORMATX), the PUCCH format configured for the PUCCH resource is PUCCH-format 4. Therefore, the PUCCH resource includes the number of symbols for PUCCH transmission provided by nrofSymbols, the OCC length provided by occ-Length, the OCC index provided by occ-index, and the first symbol for PUCCH transmission provided by startingSymbolIndex. The number of symbols for PUCCH transmission (e.g., nrofSymbols) can be any integer in the range of 4 to 14, the OCC length (e.g., OCC length) can be enumerated as {n2, n4}, the OCC index (e.g., OCC index) can be enumerated as {n0, n1, n2, n3}, and the first symbol of PUCCH transmission (e.g., startingSymbolIndex) can be any integer in the range of 0 to 10.

[0096] In one embodiment, if useInterlacePUCCH-PUSCH is provided to the UE (e.g., electronic device 110) in BWP-UplinkDedicated and the resource format indicates PUCCH format 1016 or PUCCH-format2-r16, the PUCCH resources also include (if provided) the index of the second interleaving set of interleaving set 1 or interleaving set 1-r16. The index of the second interleaving set (e.g., interleaving set 1 or interleaving set 1-r16) can be any integer in the range of 0 to 9. In an example, if the resource format indicates PUCCH format 1015 or PUCCH-format2-r16 and interleaving set 1 is not provided, the PUCCH resources include (if provided) the OCC length indicated by OCC-length-r16 and the OCC index indicated by OCC-index-r16. In an example, the UE may assume that the OCC with the lowest index in the first interleaving set PRBs, and if configured, the second interlace set is used for PUCCH transmission.

[0097] refer to Fig.11 , in one example, PUCCH-format2-r16 and PUCCH-format3-r16 include the number of symbols for PUCCH transmission provided by nrofSymbols and the first symbol of PUCCH transmission provided by startingSymbolIndex. For PUCCH-format2-r16, the number of symbols for PUCCH transmission (e.g., nrofSymbols) can be 1 or 2, and the first symbol of PUCCH transmission (e.g., startingsymbolndex) can be any integer in the range of 0 to 13. For PUCCH-format3-r16, the number of symbols for PUCCH transmission (e.g., nrofSymbols) can be any integer in the range of 4 to 14, and the first symbol of PUCCH transmission (e.g., startingSymbolIndex) can be any integer in the range of 0 to 10.

[0098] Fig.12 1 is a flowchart of an example process 1200 according to an embodiment of the present invention. The process 1200 may be implemented by an electronic device (eg, the electronic device 110). The process 1200 starts from step S1201 and proceeds to step S1210.

[0099] In step S1210, configuration information for PUCCH resource configuration may be received from a network (e.g., network 101) in a wireless communication system (e.g., wireless communication system 100). As described above, as shown in reference figures 4-8, the configuration information (e.g., configuration information 140) may indicate a first interleaving set of a first group of frequency-domain physical resources including PUCCH resources. In addition, in various examples, the configuration information may indicate a second interleaving set of PUCCH resources, the number of one or more interleaving sets, subband allocation information, etc. In addition to the above-mentioned frequency-domain physical resource information, the configuration information also indicates time-domain resource information (e.g., a starting symbol such as a starting symbol index, the number of symbols, etc.). The configuration information may be based on the PUCCH resource configuration (e.g., respectively, such as Figure 4-8 420, 520, 620, 720 and 820) and PUCCH format configurations corresponding to the PUCCH formats (e.g., respectively as shown in Figure 4-8 430, 530, 630, 730 and 830) are used to indicate frequency domain physical resource information and time domain resource information. Figure 2 , 4 -8, 10 and 11 describe various PUCCH formats. In one example, the configuration information indicates a PUCCH format configuration for PUCCH resource configuration, and the PUCCH format configuration indicates a second interlace set.

[0100] As mentioned above Figure 4-8 In step S1220, resource allocation of PUCCH resources in the frequency domain may be determined based at least on the first interleaving set.

[0101] At step S1230, UCI may be sent from the electronic device to the network on the PUCCH resources as described above. Process 1200 proceeds to step S1299 and ends.

[0102] The steps in process 1200 may be implemented in any suitable order. In addition, one or more steps in process 1200 may be modified, combined, or omitted. Other steps may be added. For example, before S1230, as described above, resource allocation of PUCCH resources in the time domain may be determined based on time domain resource information (e.g., the starting symbol index and the number of symbols (if available) indicated by the PUCCH format).

[0103] Any suitable technology may be used to implement the various circuits, circuits, components, modules, etc. in the present invention, such as an integrated circuit (IC), multiple ICs, a digital signal processor (DSP), a microprocessor, a central processing unit (CPU), a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), etc. In one example, the various circuits, components, modules, etc. may also include one or more processing circuits that execute software instructions.

[0104] Although aspects of the present invention have been described in conjunction with specific exemplary embodiments, various substitutions, modifications and changes may be made to these examples. Therefore, the embodiments described in the present invention are merely illustrative and not restrictive. Changes may be made without departing from the scope set forth in the claims.
