Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to an information transmission method, apparatus, terminal device, and network device. Background Art

[0002] In a 5G NR (New Radio) system, a UE (User Equipment) needs to send uplink control information to a gNB (gNode B) through a PUCCH (Physical Uplink Control Channel). For example, the UE sends a HARQ-ACK (Hybrid Automatic Repeat reQuest - ACKnowledgment) feedback message to the gNB according to whether it correctly receives the PDSCH (Physical Downlink Shared Channel) sent by the gNB. This message belongs to one type of uplink control information; specifically, the HARQ-ACK feedback message can be carried and sent through the PUCCH. However, the capacity of the PUCCH is limited. Especially before the UE completes initial access and obtains UE-specific RRC (Radio Resource Control) configuration, all UEs that have not obtained UE-specific RRC PUCCH configuration will share a same PUCCH resource set, and this PUCCH resource set is denoted as the "initial PUCCH resource set". For a UE, this initial PUCCH resource set is determined by a method of protocol predefined combined with gNB broadcast configuration indication information.

[0003] In addition, currently, NR is about to support a Reduced Capability (RedCap) UE (i.e., a UE with reduced capabilities). An important application scenario of RedCap UEs is industrial sensor networks. Therefore, it can be foreseen that the number of RedCap UEs may be very large. When a large number of RedCap UEs simultaneously access the NR network, it may lead to excessive access delay or even access failure due to the insufficient capacity of the initial PUCCH resource set.

The network device can be used to mutually replace the received air frames and Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the management of the attributes of the air interface. For example, the network device involved in the embodiments of this application can be a network device (Base Transceiver Station, BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or a network device (NodeB) in a Wide-band Code Division Multiple Access (WCDMA), or an evolved network device (evolutional Node B, eNB or e-NodeB) in a Long Term Evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), or a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc. The embodiments of this application do not limit this. In some network architectures, the network device can include a centralized unit (centralized unit, CU) node and a distributed unit (distributed unit, DU) node, and the centralized unit and the distributed unit can also be geographically separated.

[0326] A network device and a terminal device can each use one or more antennas for Multi-Input Multi-Output (MIMO) transmission. The MIMO transmission can be Single User MIMO (SU-MIMO) or Multiple User MIMO (MU-MIMO). According to the form and quantity of the root antenna combination, the MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or it can be diversity transmission, precoding transmission, beamforming transmission, etc.

[0327] First, the content involved in the solution provided by the embodiments of the present application will be introduced below.

[0328] In the existing NR technology, the gNB indicates the index of a resource set through the broadcast system information pucch-ResourceCommon (PUCCH common resource indication information). The index value ranges from 0 to 15 and is used to indicate which initial PUCCH resource set corresponding to the configuration in Table 1 (Table 1 is predefined currently) the UE uses.

[0329] Table 1: PUCCH resource sets before dedicated PUCCH resource configuration

[0330]

[0331] For example, if the resource set index value is 3, it means that the initial PUCCH resource set is the row corresponding to index 3 in Table 1 above. The PUCCH used by the PUCCH in this initial PUCCH resource set is of PUCCH format 1. The first symbol in a slot is symbol 10, and the number of symbols is 4. The PRB offset (that is ) for determining the PUCCH frequency domain position is 0, and the available set of initial cyclic shift indices (initial CS index) includes 2, which are {0, 6}. in Table 1 above is the bandwidth of the uplink initial BWP.

[0332] In Table 1 above, there are only 16 PUCCH resources in the initial PUCCH resource set corresponding to any row configuration; moreover, for PUCCH format 1 among them, currently, the index of its Orthogonal Cover Code (OCC) is specified as 0. The OCC with index 0 is an all-1 sequence, and scrambling with an all-1 sequence is equivalent to scrambling without using any mask.

[0333] When the UE performs HARQ-ACK feedback on the PDSCH, the resources of the specific PUCCH used are determined in the following manner:

[0334] 1. The UE determines the index of the PUCCH (i.e., the resource index) where N CCE is the number of Control Channel Elements (CCEs) included in the Control Resource Set (CORESET) where the PDCCH scheduling the PDSCH is located, n CCE,0 is the index of the first CCE among the CCEs occupied by the PDCCH that actually schedules the UE to receive the PDSCH, and Δ PRI is the value indicated by the "PUCCH Resource Indicator Field" in the Downlink Control Information DCI (carried in the PDCCH) that schedules the PDSCH, and its value range is 0 to 7. In summary, the possible value range of r PUCCH is 0 to 15. Here, it is noted that the formula symbols involved in this application represent rounding down the value within the symbol.

[0335] 2. The UE determines the Physical Resource Block (PRB) position index and the initial CS index of the PUCCH according to r PUCCH :

[0336] (1) If then:

[0337] 1) The index of the first physical resource block of the first hop hop1 of the PUCCH is The index of the first PRB of the second hop hop2 is is the bandwidth of the uplink initial BWP. N CS is the number of Initial CS indices included in the initial cyclic shift set.

[0338] 2) The Initial CS index is (i.e., equal to) r PUCCH mod N CS where N CS is the number of Initial CS indices included in the initial cyclic shift set. The symbol mod represents the remainder operation. For example, rPUCCH mod N CS represents r PUCCH divided by N CS the remainder.

[0339] (2) If then:

[0340] 1) The first PRB index of the first hop hop1 is The index of the first PRB of the second hop hop2 is

[0341] 2) Initial CS index is (r PUCCH - 8) mod N CS .

[0342] Still taking the initial PUCCH resource set as an example of the row with index 3 in Table 1 above (at this time, the initial cyclic shift index set includes 2 elements, so N CS = 2), assuming that the UE determines r according to the first CCE of the PDCCH (Physical Downlink Control Channel) and the "PUCCH Resource Indicator Field" of the DCI PUCCH = 5, then since Therefore, it can be determined that the first PRB index of the first hop of the PUCCH is The first PRB index of the second hop is And the Initial CS index is r PUCCH mod N CS = 5 mod 2 = 1, that is, Initial CS is 6 in {0, 6}. Among them: '0' in {0, 6} corresponds to index 0, and '6' corresponds to index 1.

[0343] In addition, currently, at the same moment, the network device only indicates one row in Table 1 above. The corresponding initial PUCCH resource set contains 16 PUCCH resources. That is, all UEs before obtaining the UE-specific RRC PUCCH configuration share these 16 PUCCH resources, and the capacity of the PUCCH cannot be improved by means such as OCC (the existing method is equivalent to not using OCC). Therefore, in the time of the same slot, at most 16 UEs can send PUCCH.

[0344] When a large number of RedCap UEs access NR, the capacity of the existing initial PUCCH resources may not be sufficient to support multiple RedCap UEs that have not entered the RRC connected state to send PUCCH simultaneously. This will lead to an increase in the feedback delay and access delay of RedCap UEs, and may even lead to access failure.

[0345] Based on the above, embodiments of the present application provide an information transmission method, apparatus, terminal device, and network device to solve the problem in the prior art that the terminal cannot access or the access delay is too large due to insufficient PUCCH capacity. Among them, the method, apparatus, terminal device, and network device are based on the same inventive concept.

[0398] Method 2: Use OCC to scramble PUCCH, where the number N of OCCs > 1 (corresponding to the first category set including: an orthogonal mask OCC set);

[0399] Method 3: Increase the frequency-domain resources (such as PRBs) and / or time-domain resources (such as orthogonal frequency-division multiplexing symbol groups OFDM symbol group) in the PUCCH resource set, corresponding to the first category set including: a time-domain resource set and / or a frequency-domain resource set;

[0400] II. Regarding how to specifically determine the PUCCH resources used in the "extended initial PUCCH resource set", there are the following two directions (applicable to terminal devices or network devices):

[0401] (1) Expand the range of the initial PUCCH resource index r′ PUCCH and determine the PUCCH resources according to the expanded r′ PUCCH Corresponding to determining the PUCCH resource index according to the first information and the first expansion multiple; determining the target PUCCH resource from the first PUCCH resource set according to the PUCCH resource index.

[0402] (2) Do not expand the range of the initial PUCCH resource index r PUCCH but determine at least one of the expanded CS, OCC, and time-frequency resources based on the additional sub-index on the basis of the existing PRBs and / or CS resources of the PUCCH. Corresponding to determining the target index according to the first information and the second expansion multiple; determining the target PUCCH resource from the first physical uplink control channel PUCCH resource set according to the target index.

[0403] Direction (1) and direction (2) are substantially equivalent.

[0404] Regardless of direction (1) or direction (2), the extended PUCCH resources can be specifically determined according to the following information (corresponding to the above first information):

[0405] A. Cell radio network temporary identifier C-RNTI;

[0406] B. Synchronization signal block SSB index or random access occasion RO index selected at initial access;

[0407] C. Frequency-domain PRB position of PDSCH; corresponding to the above first PRB position information;

[0408] D. Control channel element CCE of the PDCCH scheduling PDSCH; corresponding to the above first CCE information;

[0409] E. Extended PRI field (PUCCH resource indication field) information of DCI in the PDCCH scheduling the PDSCH; corresponding to the above first PRI information;

[0410] F. Specific formula (r formula when the UE is in RRC_CONNECTED); corresponding to the above first formula; specifically, the extended r′ can be determined according to this formula PUCCH formula); PUCCH .

[0411] The application scenarios of this solution will be illustrated below.

[0412] This solution can be applied to the 5G NR system, which includes network devices and terminal devices; this solution can also be applied to other systems as long as the terminal device needs to send PUCCH to the network device.

[0413] As Figure 4 shown, the applicable scenarios of this solution are illustrated (the terminal device is taken as the user equipment UE, and the network device is taken as the gNB (next-generation B node (base station of the fifth-generation mobile communication system))); among them, multiple UEs including UE1 and UE2 initiate random access to the gNB to apply for wireless network connection services; the gNB receives random access requests from at least one UE and provides wireless services for it. Data interaction and transmission are carried out between the gNB and UE1 and UE2 through wireless communication.

[0414] Thus, the network elements involved in this solution mainly include:

[0415] (1) Network devices, such as base stations, gNBs;

[0416] (2) Terminal devices, such as user equipment, UE, RedCap UE.

[0417] The solution provided in the embodiments of this application will be specifically illustrated below. The terminal device is taken as the UE, and the network device is taken as the base station.

[0418] Example 1

[0419] In this example, through Method 1: increasing the number of initial cyclic shift indexes in the PUCCH resource set to expand the capacity of the initial PUCCH resource set.

[0420] Regarding expanding the capacity of the initial PUCCH resource set:

[0421] In all current configurations of the initial PUCCH resource set (refer to Table 1 above), the available set of initial cyclic shift indexes (Set of initial CS indexes) is {0, 3}, {0, 4, 8}, {0, 6} or {0, 3, 6, 9}.

[0422] In this example, an 'extended Set of initial CS indexes' is used. That is, in the initial PUCCH resource set, in at least one row of the configuration, the number of initial CS indexes in the 'Set of initial CS indexes' is greater than the number in the 'original Set of initial CS indexes'. Specifically, in this example, the number of indexes in the new Set is N S times (corresponding to the first expansion multiple or the second expansion multiple mentioned above), and N S is a positive integer greater than 1.

[0423] Specifically, for example, a new table of the initial PUCCH resource set can be predefined as Table 2 below, where some of the Set of initial CS indexes are new configurations with more indexes than those in the original table of the initial PUCCH resource set (corresponding to Table 1 above), such as the partial Set of initial CS indexes corresponding to indexes 7 to 14.

[0424] Table 2

[0425]

[0426]

[0427] The above Table 2 is only for illustration, and there can be other configurations with more initial cyclic shift indexes, such as expanding {0, 6} to {0, 2, 4, 6, 8, 10}, which is not limited here.

[0428] After increasing the initial PUCCH resource capacity by using more initial cyclic shift indexes, it is also necessary to consider how to indicate the extended PUCCH resources. Among them, the PUCCH resources include dimensions such as PRB positions and initial cyclic shift indexes.

[0429] In this example, there are mainly two directions for indicating the new (with an increased number of initial cyclic shift indexes) PUCCH resources:

[0430] (1) Extend the range of the initial PUCCH resource index r PUCCH (denote the extended initial PUCCH resource index as r′ PUCCH ), and determine the PUCCH resources according to the extended r′ PUCCH .

[0431] Specifically, the following methods can be used to extend r′PUCCH :

[0432] A. Extended according to C-RNTI;

[0433] C-RNTI is a cell radio network temporary identifier configured by the base station for the UE. Different UEs under the same cell have different C-RNTIs. Therefore, the C-RNTI can be used to determine the initial PUCCH resource index r' of the extension PUCCH .

[0434] Some feasible methods include:

[0435] Or,

[0436] (SFN is the system frame number, specifically referring to the frame number of the system frame where the UE sends the PUCCH, or the frame number of the system frame where the PDSCH corresponding to the PUCCH is located, or the frame number of the system frame where the PDCCH scheduling the PDSCH is located. Introducing SFN can make the indexes of the initial cyclic shift of the PUCCH at different times different, which is beneficial to randomize the interference of the UE to other cells); but not limited thereto.

[0437] In short, the extended r' can be determined according to the C-RNTI PUCCH That's all, and this solution is applicable.

[0438] B. Extended according to the SSB index or RO index selected during initial access;

[0439] During the initial access phase, the UE will select the SSB and RO for random access according to some signal measurement results. The SSB index I selected by the UE SSB or the RO index I RO can be used to determine r' PUCCH .

[0440] Some feasible methods include:

[0441] Or,

[0442] but not limited thereto.

[0443] In short, the extended r' can be determined according to I SSB or I RO That's all, and this solution is applicable. PUCCH That's all, and this solution is applicable.

[0444] C. Extended according to the frequency-domain PRB position of the PDSCH;

[0445] In this method, the PRB index I of the PDSCH PRB, optionally, it can be the index of the first (i.e., the lowest frequency) PRB of the PDSCH or the index of the last (i.e., the highest frequency) PRB of the PDSCH. This I PRB is used to determine r′ PUCCH .

[0446] Some feasible methods include:

[0447] Or,

[0448] but not limited thereto. Among them, Floor(x) represents rounding down x, which is equivalent to ceil represents rounding up x, which is equivalent to

[0449] In short, the extended r′ can be determined according to I PRB and this solution can be applied accordingly. PUCCH That's all.

[0450] D. Extension according to the CCE of the PDCCH scheduling the PDSCH;

[0451] The CCE index I of the PDCCH CCE , optionally, can be the index of the first CCE of the PDCCH or the index of the last PRB. It should be noted that different from the PDSCH, the first and last CCEs here are determined in a predefined manner and are not necessarily the lowest frequency or the highest frequency CCEs.

[0452] Some feasible methods include:

[0453]

[0454] but not limited thereto.

[0455] In short, the extended r′ can be determined according to I CCE and this solution can be applied accordingly. PUCCH That's all.

[0456] E. Extension according to the extended PRI information of the DCI in the PDCCH scheduling the PDSCH;

[0457] Currently, the DCI for scheduling the PDSCH received by the UE during the initial access phase includes a 3-bit PRI field, which is used to determine where Δ PRI is the indication value of the PRI field in the DCI.

[0458] In this method, the PRI field in the DCI is extended from 3 bits to 3 + x bits, where The UE can calculate according to the original formula Determine r' in the range of 0 to 2 4+x -1 PUCCH .

[0459] F. Determine r according to a specific formula (for a UE in the RRC_CONNECTED state, the formula corresponding to the above first formula) and expand; PUCCH The formula is expanded according to the above first formula;

[0460] Currently, after the UE completes initial access, it will enter the RRC_CONNECTED state. The base station can configure UE-specific PUCCH resource sets for the UE, and up to 4 PUCCH resource sets can be configured. Among them, for the first UE-specific PUCCH resource set, it can include R PUCCH PUCCH resources. When R PUCCH is greater than 8, r PUCCH is determined according to the following formula:

[0461]

[0462] For the expanded initial PUCCH resource set, obviously R PUCCH > 8. Therefore, in this method, the above formula is directly reused to indicate r' PUCCH . In the above formula, p represents the index of the CORESET, which is equivalent to p = 0 in this method.

[0463] Furthermore, in direction (1), after determining r' through the above methods A to F, etc., the UE determines the PRB position index and (expanded) initial CS index of the PUCCH according to r' PUCCH . PUCCH

[0464] A feasible method is:

[0465] (1) If then:

[0466] 1) The index of the first physical resource block of the first hop hop1 of the PUCCH is The index of the first PRB of the second hop hop2 is

[0467] 2) The Initial CS index is r' PUCCH mod(N S × N CS ).

[0468] (2) If then:

[0469] 1) The index of the first PRB of the first hop hop1 is​ The index of the first PRB of the second hop hop2 is

[0470] 2) The Initial CS index is (r′ PUCCH -8) mod (N S × N CS ).

[0471] In the above formula, a new parameter N′ CS can also be used to represent N S × N CS , and the two are equivalent.

[0472] There can also be other methods to determine the PRB and (extended) initial CS index according to r′ PUCCH , and this solution is also applicable.

[0473] (II) Without expanding the range of the initial PUCCH resource index r PUCCH , but determining the extended CS based on the existing PRB and CS resources of the PUCCH through an additional sub-index;

[0474] Specifically, in direction (II), it is often necessary to determine a sub-index of the initial cyclic shift (denoted as I S ), and further determine the index of the initial cyclic shift in the extended initial PUCCH resource set according to this sub-index, denoted as I new . Essentially, both direction (II) and direction (I) achieve the indication of the extended initial PUCCH resource through additional information (such as C-RNTI, SSB index, etc.).

[0475] Specifically, in direction (II), the following method can be used to indicate the specific PRB of the PUCCH after expanding the number of initial cyclic shift indexes:

[0476] A. Determine according to C-RNTI;

[0477] 1) First, an initial cyclic shift sub-index (denoted as I S , corresponding to the above target index, and the same in the following calculation methods) needs to be obtained according to C-RNTI:

[0478] It can be calculated according to the formula: I S = C-RNTI mod N S (As mentioned before, the number of indexes in the new Set is N S times that in the original Set), and I S can be calculated;

[0479] Or, it can be calculated according to the formula: IS =(C - RNTI + SFN) mod N S Calculate to obtain I S ;

[0480] Or other methods, as long as I can be uniquely determined by C - RNTI S And I S ={0, 1, …, N S - 1} is fine.

[0481] 2) Then, according to the above index r PUCCH mod N CS or (r PUCCH - 8) mod N CS (denoted as I, corresponding to the above initial index, and the same applies to the following calculation methods), and I S , determine the initial cyclic shift index I in the new set new (corresponding to the above final index, and the same applies to the following calculation methods). For example:

[0482] According to the formula I new = I × N S + I S , determine the initial cyclic shift index in the extended initial PUCCH resource set.

[0483] A specific example is: For example, assume the original initial cyclic shift set is {0, 6}, that is, N CS = 2, I = 0, 1; and the new set is {0, 2, 4, 6, 8, 10}, the expansion multiple N S = 3, the sub - index I S = 0, 1, 2; if I = 0, I S = 1 is obtained through the above calculation or indication method, then I new = 0 × 3 + 1 = 1; again, if I = 1, I S = 2, then I new = 1 × 3 + 2 = 5.

[0484] It can be understood that in the new set {0, 2, 4, 6, 8, 10}, it can be considered that the original index I no longer directly indicates the specific initial cyclic shift index, but indicates a subset in the new set. I = 0 corresponds to the subset {0, 2, 4}, I = 1 corresponds to the subset {6, 8, 10}, and I S then indicates which specific index in a subset is used as the initial cyclic shift index in the new set; or, it can be considered that the original index I no longer directly indicates the specific initial cyclic shift index, but indicates the starting point of the index in the new set. I = 0 corresponds to 0 starting from {0, 2, 4, 6, 8, 10}, I = 1 corresponds to 6 starting from {0, 2, 4, 6, 8, 10}, and IS It indicates how many indices need to be offset from a certain starting point to obtain the initial cyclic shift index under the new set.

[0485] B. Determined according to the SSB index or RO index selected at initial access;

[0486] First, it is necessary to obtain a sub-index of the initial cyclic shift (denoted as I SSB or RO index I RO ) based on the SSB index I S selected by the UE during the initial access phase:

[0487] Similar to the situation in A above, according to the formula I S = I SSB mod N S , or I S = (I SSB + SFN) mod N S , or I S = I RO mod N S , or I S = (I RO + SFN) mod N S , etc., to determine I S , and then use the method similar to that in A above to determine I S and I to determine I new .

[0488] C. Determined according to the frequency-domain PRB position of the PDSCH;

[0489] In this method, the PUCCH resource (such as the I new index) used by the UE for HARQ-ACK feedback for a certain PDSCH is determined according to the PRB index of this PDSCH. Among them:

[0490] The PRB index I PRB of the PDSCH can optionally be the index of the first (i.e., the lowest frequency) PRB of the PDSCH, or the index of the last (i.e., the highest frequency) PRB of the PDSCH.

[0491] Then, similar to the situation in A above, according to formula 1: I S = I PRB mod N S , or formula 2: or other formulas to determine I S , and then use the method similar to that in A above to determine I S and I to determine I new , which will not be elaborated here. Among them, Indicates the bandwidth of the downlink BWP for transmitting PDSCH.

[0492] The effect difference between the above two formulas (Formula 1 and Formula 2) is as Figure 5 shown, where it is assumed that N S = 4. Formula 1 corresponds to: the index I S cyclically changes as I PRB increases, while Formula 2 corresponds to: dividing the PRB as a whole into N S regions, and I S depends on which region the PRB index of the PDSCH is in. The DL initial BWP in the figure represents the downlink initial bandwidth part.

[0493] D. Determined according to the CCE of the PDCCH scheduling the PDSCH;

[0494] In this method, the PUCCH resource (such as the I new index) used by the UE for HARQ-ACK feedback for a certain PDSCH is determined according to the CCE index of the PDCCH scheduling this PDSCH.

[0495] The CCE index I CCE of the PDCCH can optionally be the index of the first CCE of the PDCCH or the index of the last PRB. It should be noted that different from the PDSCH, the first CCE and the last CCE here are not necessarily the lowest-frequency or highest-frequency CCEs.

[0496] Then, similar to the situation in A above, according to Formula 1: I S = I CCE mod N S , or Formula 2: I S = floor(I CCE / ceil(N CCE / N S ))), or other formulas to determine I S , and then use the method similar to that in A above to determine I S and I to determine I new , which will not be elaborated here. Among them, N CCE represents the number of CCEs included in the control resource set (CORESET) where the PDCCH scheduling the PDSCH is located.

[0497] E. Determined according to the extended PRI information of the DCI in the PDCCH scheduling the PDSCH;

[0498] Currently, the DCI of the PDSCH received by the UE during the initial access phase includes a 3-bit PRI field, which is used to determine where Δ PRI is the indication value of the PRI field.

[0499] In this method, the PRI field is extended from 3 bits to 3 + x bits to indicate a specific initial cyclic shift index in the expanded initial cyclic shift index set. For example:

[0500] 1) The 3 bits in the 3 + x bits still indicate Δ in the range of 0 to 7 according to the current method PRI , so that the UE can determine r in the range of 0 to 15 according to and further determine I; while the x bits in the 3 + x bits (which can indicate 0, 1, 2,..., 2 PUCCH -1) indicate I x and determine I through the method in A above S , where new In short, the capacity of the initial PUCCH resource set can be expanded by increasing the number of initial cyclic shift indices in the PUCCH resource set. Specifically, the above methods A - E can be used to determine which initial cyclic shift index (in the expanded initial PUCCH resource set) to use.

[0501]

[0502] Furthermore, considering how the UE determines whether to use the new initial PUCCH resource set (the expanded set) and / or the original PUCCH resource set (the set before expansion); the embodiments of the present application provide the following content:

[0503] This part can also be used for subsequent examples. From the use of the new initial PUCCH resource set and / or the original initial PUCCH resource set, the RedCap UE can use the appropriate initial PUCCH resource set in the following way:

[0504] (1) The predefined method (corresponding to the above-mentioned terminal device belonging to the predefined first type of terminal). For example, it can be stipulated that: the RedCap UE, or the UE supporting PUCCH capacity expansion, uses the expanded (new) initial PUCCH resource set, and the non-RedCap UE (non-RedCap UE) or the UE not supporting PUCCH capacity expansion still defaults to using the original initial PUCCH resource set. This method is simple to implement and can also make the network system have better compatibility.

[0505] ​(2) Semi-static indication method (corresponding to the system information received by the network device through broadcast transmission mentioned above). For example, the base station can broadcast system messages (such as System Information Block SIB1), and indicate in SIB1 whether the initial PUCCH resource set used by the RedCap UE (or the UE supporting PUCCH expansion) is a new set or the original set. This method has better flexibility compared to the predefined method.

[0506] (3) DCI indication method (corresponding to the downlink control information DCI received from the network device as mentioned above). For example, in the DCI for scheduling the UE to receive PDSCH (such as the DCI for scheduling the transmission of Msg4), use 1-bit information therein to indicate whether the initial PUCCH resource set used by the RedCap UE (or the UE supporting PUCCH expansion) for feedback on the PDSCH in the PUCCH is a new set or the original set. This 1-bit information can be obtained by further expanding the PRI field or using the redundant bits not used in the current DCI. This method has the highest flexibility.

[0507] It should be noted here that the extended (new) initial PUCCH resource set can be implemented by defining a new initial PUCCH resource set. Of course, it is also possible not to predefine a new table, but only define a new Set of initial CS indexes. For example, new Set0 of initial CS indexes and Set1 of initial CS indexes can be defined for PUCCH format 0 and PUCCH format 1 respectively; there is no limitation here.

[0508] Example 2

[0509] In this example, through Method 2: Use OCC (Orthogonal Cover Code) to scramble the PUCCH to expand the capacity of the initial PUCCH resource set.

[0510] The basic principle of OCC scrambling is that after the transmitting end scrambles the sequence with mutually orthogonal OCC codes, the receiving end can distinguish the sequences of different OCC codes through coherent detection methods. In the current NR, it is stipulated that the index of the OCC of the PUCCH in the initial PUCCH resource set is 0, and the OCC with index 0 is a sequence of all 1s. Using the all-1 OCC sequence for scrambling is actually equivalent to not using any OCC for scrambling.

[0511] Regarding the expansion of the capacity of the initial PUCCH resource set:

[0512] In this example, different OCC codes are used to scramble the PUCCH in the initial PUCCH resource set. The same PUCCH scrambled with multiple mutually orthogonal OCC codes can be detected and distinguished by the base station even when transmitted using the same time-frequency resources, thereby increasing the capacity of the PUCCH.

[0513] It should be noted that the use of OCC in this example is applicable to PUCCH format 1.

[0514] In this solution, there is no restriction on the specific OCC codes used, as long as they are orthogonal codes of appropriate length. A possible example is to use the orthogonal codes specified for PUCCH format 1 that are currently defined (usually only used in non-initial PUCCH):

[0515] Table 3: Orthogonal Sequences for PUCCH Format 1 for PUCCH format 1 (where m in the formula here represents the m-th number in the sequence, and φ(m) represents the value of the m-th number in the sequence)

[0516]

[0517] The PUCCH in the initial PUCCH resource set can be scrambled by using the OCC codes specified in the above table.

[0518] A specific example:

[0519] Suppose the initial PUCCH resource set is configured with the configuration index 7 in Table 1. At this time, the format of the initial PUCCH is PUCCH format 1, and the time domain length is 10 OFDM symbols; since the initial PUCCH must use frequency hopping within a time slot, and the time domain length of each hop is half of the total length, so it is 5 OFDM symbols. Therefore, the OCC corresponds to the row in the above Table 3. At this time, there are 5 mutually orthogonal OCC codes, which are respectively the row, and the codes with indexes i = 0, 1, 2, 3, 4, which is equivalent to expanding the original OCC code by times. These 5 OCC codes can be used to scramble the PUCCH with a length of 10 OFDM symbols (and frequency hopping within a time slot).

[0520] Regarding how to indicate the extended PUCCH resources; specifically, for the index i of the OCC that the UE should use, similar to Example 1, there are two feasible directions:

[0521] Direction (1) is to extend the initial PUCCH resource index to r′ PUCCH and according to the extended r′ PUCCHDetermine the PUCCH resources (including OCC in addition to PRB and initial CS). In this direction, for how to determine r′ PUCCH , specifically, the method of determining r′ in Example 1 can be referred to PUCCH . The method is the same. It should be noted that (i.e., the OCC index expansion multiple) is used to replace N in Example 1 S (the initial cyclic shift index expansion multiple). Specifically as follows:

[0522] A. Expand according to C-RNTI;

[0523] C-RNTI is the cell radio network temporary identifier configured by the base station for the UE. Different UEs under the same cell have different C-RNTIs. Therefore, the C-RNTI can be used to determine the expanded initial PUCCH resource index r′ PUCCH .

[0524] Some feasible methods include:

[0525] Or,

[0526] (SFN is the system frame number, specifically referring to the frame number of the system frame where the UE sends the PUCCH, or the frame number of the system frame corresponding to the PDSCH of the PUCCH, or the frame number of the system frame where the PDCCH scheduling the PDSCH is located. Introducing SFN can make the indexes of the initial cyclic shifts of the PUCCH at different times different, which is beneficial to the interference randomization of the UE to other cells); but not limited to this.

[0527] In short, the expanded r′ can be determined according to the C-RNTI PUCCH , and this solution is applicable.

[0528] B. Expand according to the SSB index or RO index selected during initial access;

[0529] During the initial access phase, the UE will select the SSB and RO for random access according to some signal measurement results. The SSB index I SSB or RO index I RO selected by the UE can be used to determine r′ PUCCH .

[0530] Some feasible methods include:

[0531] Or,

[0532] but not limited to this.

[0533] In summary, the extended r′ can be determined according to I SSB or I RO and this solution is applicable in all cases. PUCCH That's all.

[0534] C. Extended according to the frequency-domain PRB position of PDSCH;

[0535] In this method, the PRB index I of PDSCH PRB , optionally, can be the index of the first (i.e., the lowest-frequency) PRB of PDSCH, or the index of the last (i.e., the highest-frequency) PRB of PDSCH. This I PRB is used to determine r′ PUCCH .

[0536] Some feasible methods include:

[0537] Or,

[0538] but not limited to this. Among them, Floor(x) represents rounding down x, which is equivalent to ceil represents rounding up x, which is equivalent to

[0539] In summary, the extended r′ can be determined according to I PRB and this solution is applicable in all cases. PUCCH That's all.

[0540] D. Extended according to the CCE of the PDCCH scheduling PDSCH;

[0541] The CCE index I of PDCCH CCE , optionally, can be the index of the first CCE of PDCCH, or the index of the last PRB of PDCCH. It should be noted that different from PDSCH, the first and last CCEs here are determined in a predefined manner and are not necessarily the lowest-frequency or highest-frequency CCEs.

[0542] Some feasible methods include:

[0543]

[0544] but not limited to this.

[0545] In summary, the extended r′ can be determined according to I CCE and this solution is applicable in all cases. PUCCH That's all.

[0546] E. Extended according to the extended PRI information of the DCI in the PDCCH scheduling PDSCH;

[0547] Currently, the DCI for scheduling PDSCH received by the UE during the initial access phase includes a 3-bit PRI field, which is used to determine where Δ PRI is the indication value of the PRI field in the DCI.

[0548] In this method, the PRI field in the DCI is extended from 3 bits to 3 + x bits, where The UE can determine r′ in the range of 0 to 2 -1 according to the original formula 4+x -1. PUCCH .

[0549] F. Extended according to a specific formula (the formula for determining r of the UE in the RRC_CONNECTED state, corresponding to the above first formula); PUCCH The formula for the UE in the RRC_CONNECTED state, corresponding to the above first formula) is extended;

[0550] Currently, when the UE completes the initial access, it will enter the RRC connected state (i.e., the RRC_CONNECTED state). The base station can configure UE-specific PUCCH resource sets for the UE, and up to 4 PUCCH resource sets can be configured. Among them, for the first UE-specific PUCCH resource set, it can include R PUCCH PUCCH resources. When R PUCCH is greater than 8, r PHCCH is determined according to the following formula:

[0551]

[0552] For the extended initial PUCCH resource set, it is obvious that R PUCCH > 8. Therefore, in this method, the above formula is directly reused to indicate r′ PUCCH . In the above formula, p represents the index of the CORESET, which is equivalent to p = 0 in this method.

[0553] When determining the PRB position index, the initial CS index, and the OCC index i of the PUCCH according to r′ PUCCH , a feasible method is as follows:

[0554] (1) Calculate the intermediate variable r″ PUCCH = r′ PUCCH mod 16;

[0555] (2) Calculate

[0556] (3) If then:

[0557] 1) The index of the first physical resource block of the first hop hop1 of the PUCCH is The index of the first PRB of the second hop hop2 is

[0558] 2) The Initial CS index is r″ PUCCH mod N CS 。

[0559] (4) If then:

[0560] 1) The index of the first PRB of the first hop hop1 is The index of the first PRB of the second hop hop2 is

[0561] 2) The Initial CS index is (r″ PUCCH - 8) mod N CS 。

[0562] There can also be other methods for determining the PRB, initial CS index, and OCC index based on r′ PUCCH This solution is also applicable.

[0563] In this example, in direction (two), the range of the initial PUCCH resource index r PUCCH is not extended, but a sub - index of OCC (i.e., i) needs to be determined; essentially, both direction (two) and direction (one) use additional information (such as C - RNTI, SSB index, etc.) to indicate the extended initial PUCCH resource.

[0564] Specific methods for determining the OCC index i in direction (two) can be:

[0565] A. Determine according to C - RNTI;

[0566] Refer to the method for determining I S in Example 1, which can also be used to determine the OCC index i. It should be noted that (i.e., the OCC index expansion multiple) is used to replace N S (the initial cyclic shift index expansion multiple) in Example 1, and there is no need to calculate I new , but calculate i.

[0567] For example, i = C - RNTI mod or i = (C - RNTI + SFN) mod is calculated to obtain i; or other methods, as long as i can be uniquely determined by C - RNTI and that's okay.

[0568] B. Determine according to the SSB index or RO index selected during initial access;

[0569] Referring to the method for determining I in Example 1, the same method can be used to determine the OCC index i. It should be noted that S (i.e., the total number of OCC indices) is used to replace N in Example 1 (i.e., the total number of initial cyclic shift indices), and there is no need to calculate I S anymore, but calculate i instead. Specifically: new

[0570] According to the SSB index I SSB or the RO index I RO selected by the UE during the initial access phase, an OCC index (denoted as i) can be obtained:

[0571] Similar to the case of A above, i can be determined according to the formula i = I SSB or i = (I SSB + SFN) mod or i = I RO mod or i = (I RO + SFN) mod and other methods to determine i.

[0572] C. Determine according to the frequency-domain PRB position of the PDSCH;

[0573] Referring to the method for determining I in Example 1, the same method can be used to determine the OCC index i. It should be noted that S (i.e., the total number of OCC indices) is used to replace N in Example 1 (i.e., the total number of initial cyclic shift indices), and there is no need to calculate I S anymore, but calculate i instead. Specifically: new

[0574] In this method, the PUCCH resource (such as the i index) used by the UE for HARQ-ACK feedback for a certain PDSCH is determined according to the PRB index of the PDSCH. Among them:

[0575] The PRB index I PRB of the PDSCH can optionally be the index of the first (i.e., the lowest frequency) PRB of the PDSCH, or the index of the last (i.e., the highest frequency) PRB of the PDSCH.

[0576] Then, similar to the case of A above, i can be determined according to Formula 1: i = I PRB mod or Formula 2: or other formulas to determine i. Among them, represents the bandwidth of the downlink BWP for transmitting the PDSCH.

[0577] The difference in the effects of the above two formulas (Formula 1 and Formula 2) can be similarly referred to Figure 5 , where it is assumed that Formula 1 corresponds to: the index i cyclically changes as I PRB increases, while Formula 2 corresponds to: dividing the PRB as a whole into regions, and i depends on which region the PRB index of the PDSCH is in. The DL initial BWP in the figure represents the downlink initial bandwidth part.

[0578] D. Determined according to the CCE of the PDCCH scheduling the PDSCH;

[0579] Referring to the method for determining I S in Example 1, the same method can be used to determine the OCC index i. It should be noted that (i.e., the total number of OCC indices) is used to replace N S (the total number of initial cyclic shift indices) in Example 1, and there is no need to calculate I new , but calculate i. Specifically:

[0580] In this method, the PUCCH resource (such as the i index) used by the UE for HARQ-ACK feedback for a certain PDSCH is determined according to the CCE index of the PDCCH scheduling the PDSCH.

[0581] The CCE index I CCE of the PDCCH, optionally, can be the index of the first CCE of the PDCCH or the index of the last PRB. It should be noted that different from the PDSCH, the first CCE and the last CCE here are not necessarily the CCEs with the lowest frequency or the highest frequency.

[0582] Then, similar to the situation in A above, according to Formula 1: i = I CCE mod or Formula 2: or other formulas to determine i. Among them, N CCE represents the number of CCEs included in the control resource set (CORESET) where the PDCCH scheduling the PDSCH is located.

[0583] E. Determined according to the extended PRI information of the DCI in the PDCCH scheduling the PDSCH;

[0584] Referring to the method for determining I S in Example 1, the same method can be used to determine the OCC index i. It should be noted that (i.e., the total number of OCC indices) is used to replace N S(Total number of initial cyclic shift indices), and no longer need to calculate I new , but calculate i. Specifically:

[0585] Currently, the DCI for scheduling PDSCH received by the UE during the initial access phase includes a 3-bit PRI field, which is used to determine Where Δ PRI This is the indication value of the PRI domain.

[0586] In this method, the PRI field is extended from 3 bits to 3+x bits to indicate a specific initial cyclic shift index in the expanded initial cyclic shift index set. For example:

[0587] 1) The 3 bits in the 3+x bits still follow the current method, indicating a delta in the range of 0 to 7 PRI , so that the UE can Determine r in the range of 0 to 15 PUCCH , and further determine the initial OCC index (corresponding to the above initial index); and the x bits in the 3+x bits (can indicate 0, 1, 2, ..., 2 x -1) indicates i;

[0588] In summary, different OCC codes may be used to scramble the PUCCH in the initial PUCCH resource set to expand the capacity of the initial PUCCH resource set. Specifically, at least one of the above methods AE may be used to determine which OCC code to use.

[0589] It is noted here that the relevant contents in Example 1 can be adaptively adjusted and applied to the solution in Example 2, and will not be repeated here.

[0590] In addition, in this example, since the initial CS domain is not extended, there is no need to calculate I as in Example 1. new .

[0591] Example 3

[0592] In this example, method three is adopted: increasing the number of available PRBs and / or time domain symbol groups in the initial PUCCH resource set to expand the capacity of the initial PUCCH resource set.

[0593] Currently, through Determine r PUCCH (value range 0 to 15, a total of 16 states), and then according to the index number N in the initial circular shift index set CS , respectively determine the PRB position of PUCCH (such as ) and the initial cyclic shift index (such as r PUCCH modN CS ).

[0594] In summary, currently, in the frequency domain, the number of PRBs used for the initial PUCCH resources is very limited. For example, if N CS = 4, the total number of actually used PRBs is only 4; if N CS = 2, the number of actually used PRBs is only 8. In the time domain, only one symbol group is used in each time slot, that is, the symbol group starting from the first symbol and lasting for the number of symbols. For example, in the initial PUCCH resource set with index 0 in Table 4 below, for each PUCCH resource in it, it occupies only the last 2 symbols of one time slot in the time domain (starting from symbol 12 and lasting for 2 symbols).

[0595] Table 4

[0596]

[0597] Regarding expanding the capacity of the initial PUCCH resource set:

[0598] In this example, in the frequency domain, the capacity of the initial PUCCH set can be expanded by increasing the number of available PRBs in the initial PUCCH resource set to K f times (K f is an integer greater than 1); the expansion of PRB resources in the frequency domain can be used for all initial PUCCH resource set configurations.

[0599] In the time domain, it can also be expanded from including only one symbol group in one time slot in the initial PUCCH resource set to K t symbol groups (K t is an integer greater than 1). Optionally, the durations (number of symbols) of these symbol groups are the same, only the first symbol is different, and these symbol groups do not overlap with each other. It should be noted that this method is applicable to the PUCCH resource set configurations where the number of symbols of PUCCH does not exceed 7.

[0600] Table 5 below gives an example of expanding time domain resources. For the initial PUCCH resource configurations 0 - 6, by increasing the optional values of the first symbol in one time slot, the time domain resources are expanded by K t = 2 times, so the PUCCH resources under these configurations are also expanded by 2 times.

[0601] Table 5

[0602]

[0603] In this example, only the frequency-domain resources can be expanded, or only the time-domain resources can be expanded, or both the frequency-domain and time-domain resources can be expanded. When both the frequency-domain and time-domain are expanded, the expanded resources in the time-frequency domain can be jointly coded and can be identified by a unified index, or can be identified by the frequency-domain and time-domain indexes respectively, which are all equivalent and are not limited herein.

[0604] Regarding how to indicate the expanded PUCCH resources, the following takes the frequency-domain expansion as an example for introduction. The cases of time-domain expansion and both time-frequency domain expansion are similar to the case of frequency-domain expansion.

[0605] Specifically, for the index of the PRB that the UE should use (denoted as ), similar to Example 1, there are two feasible directions:

[0606] Direction (1) is to expand the initial PUCCH resource index to r′ PUCCH , and determine the PUCCH resources (PRB and initial CS) according to the expanded r′ PUCCH . In this direction, for how to determine r′ PUCCH , specifically, the method for determining r′ PUCCH in Example 1 can be referred to (such as according to C-RNTI), and the method is the same. It should be noted that K f (that is, the expansion multiple of the available PRB number in the initial PUCCH resource set) is used to replace N S (the initial cyclic shift index expansion multiple) in Example 1. Specifically:

[0607] A. Expand according to C-RNTI;

[0608] C-RNTI is the cell radio network temporary identifier configured by the base station for the UE. Different UEs under the same cell have different C-RNTIs. Therefore, the expanded initial PUCCH resource index r′ PUCCH can be determined using C-RNTI.

[0609] Some feasible methods include:

[0610] Or,

[0611] (The SFN is the system frame number, specifically referring to the frame number of the system frame where the UE sends the PUCCH, or the frame number of the system frame where the PDSCH corresponding to the PUCCH is located, or the frame number of the system frame where the PDCCH scheduling the PDSCH is located. Introducing the SFN can make the indexes of the initial cyclic shifts of the PUCCH at different times different, which is beneficial to randomize the interference of the UE to other cells); however, it is not limited thereto.

[0612] In summary, the extended r′ can be determined according to the C-RNTI PUCCH That's all, and this solution is applicable.

[0613] B. Extended according to the SSB index or RO index selected at initial access;

[0614] During the initial access phase, the UE will select an SSB and an RO for random access based on some signal measurement results. The SSB index I SSB or the RO index I RO can be used to determine r′ PPCCH .

[0615] Some feasible methods include:

[0616] Or,

[0617] However, it is not limited thereto.

[0618] In summary, the extended r′ can be determined according to I SSB or I RO That's all, and this solution is applicable. PUCCH That's all, and this solution is applicable.

[0619] C. Extended according to the frequency-domain PRB position of the PDSCH;

[0620] In this method, the PRB index I PRB of the PDSCH, optionally, can be the index of the first (i.e., the lowest frequency) PRB of the PDSCH, or the index of the last (i.e., the highest frequency) PRB of the PDSCH. This I PRB is used to determine r′ PUCCH .

[0621] Some feasible methods include:

[0622] Or,

[0623] However, it is not limited thereto. Among them, Floor(x) represents rounding down x, which is equivalent to ceil represents rounding up x, which is equivalent to

[0624] In summary, it is possible to determine the extended r′ according to I PRB That's all, and this solution is applicable in all cases. PUCCH That's all, and this solution is applicable in all cases.

[0625] D. Extension according to the CCE of the PDCCH scheduling the PDSCH;

[0626] The CCE index I of the PDCCH CCE , which can optionally be the index of the first CCE of the PDCCH or the index of the last PRB. It should be noted that different from the PDSCH, the first and last CCEs here are determined in a predefined manner and are not necessarily the CCEs with the lowest or highest frequency.

[0627] Some feasible methods include:

[0628]

[0629] However, it is not limited to this.

[0630] In summary, it is possible to determine the extended r′ according to I CCE That's all, and this solution is applicable in all cases. PUCCH That's all, and this solution is applicable in all cases.

[0631] E. Extension according to the extended PRI information of the DCI in the PDCCH scheduling the PDSCH;

[0632] Currently, the DCI of the PDSCH received by the UE during the initial access phase includes a 3-bit PRI field for determining where Δ PRI is the indicated value of the PRI field in the DCI.

[0633] In this method, the PRI field in the DCI is extended from 3 bits to 3 + x bits, where the UE can determine r′ in the range of 0 to 2 -1 according to the original formula 4+x -1 range of r′ PUCCH .

[0634] F. Extension according to a specific formula (the formula for determining r for a UE in the RRC_CONNECTED (connected) state, corresponding to the above first formula); PUCCH That's all, and this solution is applicable in all cases.

[0635] Currently, when the UE completes the initial access, it will enter the RRC connected state (i.e., the RRC_CONNECTED state). The base station can configure UE-specific PUCCH resource sets for the UE, with a maximum of 4 UE-specific PUCCH resource sets. Among them, for the first UE-specific PUCCH resource set, it can include R PUCCHPUCCH resources. When R PUCCH is greater than 8, r PUCCH is determined according to the following formula:

[0636]

[0637] For the extended initial PUCCH resource set, it is obvious that R PUCCH > 8. Therefore, in this method, the above formula is directly reused to indicate r′ PUCCH . In the above formula, p represents the index of the CORESET, which is equivalent to p = 0 in this method.

[0638] Furthermore, when the number of PRBs increases to K f times the original, how to "determine the PRB index according to r′ PUCCH ", a feasible method is: "

[0639] (1) If then:

[0640] 1) The index of the first physical resource block of the first hop hop1 of the PUCCH is The index of the first PRB of the second hop hop2 is is the bandwidth of the uplink initial BWP.

[0641] 2) The Initial CS index is r′ PUCCH mod N CS .

[0642] (2) If then:

[0643] 1) The index of the first PRB of the first hop hop1 is The index of the first PRB of the second hop hop2 is

[0644] 2) The Initial CS index is (r′ PUCCH - 8 × K f ) mod N CS .

[0645] There can also be other methods to determine the PRB and the initial CS index according to r′ PUCCH , and this solution is also applicable.

[0646] In this example, in direction (2), the range of the initial PUCCH resource index r PUCCH is not extended, but a sub-index of a PRB (denoted as I k); Directions (II) and (I) both essentially indicate the extended initial PUCCH resources through additional information (such as C-RNTI, SSB index, etc.).

[0647] Specifically, the following method can be used to indicate the specific PRBs of the PUCCH after the number of PRBs is increased under Direction (II):

[0648] A. Determine according to C-RNTI;

[0649] (1) Refer to Method A in Example 1. First, a sub-index of a PRB (denoted as I k ) needs to be obtained from the C-RNTI:

[0650] It can be calculated according to the formula: I k = C-RNTI mod K f , and I k can be obtained; or,

[0651] It can be calculated according to the formula: I k = (C-RNTI + SFN) mod K f , where SFN is the system frame number, specifically referring to the frame number of the system frame where the UE sends the PUCCH, or the frame number of the system frame corresponding to the PDSCH of the PUCCH, or the frame number of the system frame where the PDCCH scheduling the PDSCH is located. k Or other methods, as long as I

[0652] can be uniquely determined by the C-RNTI and I k and I k = {0, 1,..., K f - 1} is sufficient.

[0653] (2) Then, according to the formula or (taking the first hop of PUCCH hopping as an example here, and the second hop is similar), determine the new PRB index Regarding the second hop of PUCCH hopping, for example: according to the formula or determine the new PRB index

[0654] B. Determine according to the SSB index or RO index selected during initial access;

[0655] Refer to the method for determining I S in Example 1, which can also be used to determine the sub-index I k of the PRB. Then, similar to Method A above, the index of the PRB regarding the sub-index Ik Determine specifically:

[0656] It is necessary to obtain a sub-index of the initial cyclic shift (denoted as I SSB or the RO index I RO ) according to the SSB index I selected by the UE in the initial access phase k :

[0657] Similar to the case of A above, according to the formula I k = I SSB mod K f , or I k = (I SSB + SFN) mod K f , or I k = I RO mod K f , or I k = (I RO + SFN) mod K f , etc., to determine I k .

[0658] C. Determine according to the frequency-domain PRB position of the PDSCH;

[0659] Refer to the method of determining I S in Example 1, which can also be used to determine the sub-index I k of the PRB. Then, similar to Method A above, the index of the PRB can be determined Regarding the determination of the sub-index I k specifically:

[0660] In this method, the PUCCH resource (such as index) used by the UE for HARQ-ACK feedback for a certain PDSCH is determined according to the PRB index of the PDSCH. Among them:

[0661] The PRB index I PRB of the PDSCH can optionally be the index of the first (i.e., the lowest frequency) PRB of the PDSCH, or the index of the last (i.e., the highest frequency) PRB of the PDSCH.

[0662] Then, similar to the case of A above, according to Formula 1: I k = I PRB mod K f , or Formula 2: or other formulas to determine I k . Among them, represents the bandwidth of the downlink BWP for transmitting the PDSCH.

[0663] The difference in the effects of the above two formulas (Formula 1 and Formula 2) can be similarly referred to Figure 5 , where it is assumed that K f = 4. Formula 1 corresponds to: the index I k changing cyclically as I PRB increases, while Formula 2 corresponds to: dividing the PRB as a whole into K f regions, and I k depends on which region the PRB index of the PDSCH is in. The DL initial BWP in the figure represents the downlink initial bandwidth part.

[0664] D. Determined according to the CCE of the PDCCH scheduling the PDSCH;

[0665] Refer to the method of determining I S in Example 1, which can also be used to determine the sub-index I k of the PRB. Then, similar to Method A above, the index of the PRB regarding the sub-index I k can be determined specifically as follows:

[0666] In this method, the PUCCH resource (such as the index) used by the UE for HARQ-ACK feedback for a certain PDSCH is determined according to the CCE index of the PDCCH scheduling the PDSCH.

[0667] The CCE index I CCE of the PDCCH can optionally be the index of the first CCE of the PDCCH or the index of the last PRB. It should be noted that different from the PDSCH, the first CCE and the last CCE here are not necessarily the lowest-frequency or highest-frequency CCEs.

[0668] Then, similar to the situation in A above, according to Formula 1: I k = I CCE mod K f , or Formula 2: I k = floor(I CCE / ceil(N CCE / K f ))), or other formulas to determine I k . Among them, N CCE represents the number of CCEs included in the control resource set (CORESET) where the PDCCH scheduling the PDSCH is located.

[0669] E. Determined according to the extended PRI information of the DCI in the PDCCH scheduling the PDSCH;

[0670] Refer to the method of determining I in Example 1S The method can also be used to determine the sub-index I of the PRB k . Then, similar to Method A above, the index of the PRB can be determined Regarding the determination of the sub-index I k , specifically:

[0671] Currently, the DCI for scheduling the PDSCH received by the UE during the initial access phase includes a 3-bit PRI field, which is used to determine where Δ PRI is the indication value of the PRI field

[0672] In this method, the PRI field is extended from 3 bits to 3 + x bits to indicate a specific initial cyclic shift index in the expanded initial cyclic shift index set. For example:

[0673] 1) The 3 bits in the 3 + x bits still follow the current method to indicate Δ in the range of 0 to 7 PRI , so that the UE can determine r in the range of 0 to 15 according to and further determine the initial PRB index (corresponding to the above initial index); while the x bits in the 3 + x bits (which can indicate 0, 1, 2,..., 2 PUCCH -1) indicate I x , where k In summary, the capacity of the initial PUCCH resource set can be expanded by increasing the number of available PRBs in the PUCCH resource set. Specifically, at least one of the above Methods A - E can be used to determine the index of the expanded PRB

[0674] Here, it should be noted that the relevant content in Example 1 can be adaptively adjusted and applied to the solution in Example 3, which will not be elaborated here

[0675] It should be noted that the relevant content in Example 1 can be adaptively adjusted and applied to the solution in Example 3, which will not be elaborated here

[0676] Example 4

[0677] This example is only for illustration, and the methods in the above Examples 1 - 3 can be used in combination

[0678] For example, the PUCCH capacity can be expanded by simultaneously "expanding the initial cyclic shift index" and "using OCC for scrambling". If the initial cyclic shift index set is expanded by N S times, and the OCC code used is expanded by times, then the final PUCCH capacity is expanded by times

[0679] In the case of combined use, the methods in the above examples can still be used to determine the resources of the PUCCH with expanded capacity

[0680] Taking the sub - index (I S , I k , i, etc.) determined by at least one of the methods A - E in the above example as an example, when using 2 (or 3) methods to expand the initial PUCCH capacity, different 2 (or 3) methods can be selected from A - E and used in combination to obtain sub - indexes respectively, and further determine at least one of the new initial cyclic shift index, OCC index, and PRB index.

[0681] For another example, the same method in A - E can be used to obtain multiple different sub - indexes (I S , I k , i). Taking the need to obtain three sub - indexes as an example, using C - RNTI as an example, the following formula can be used to obtain (I S , I k , i) respectively according to the same C - RNTI:

[0682] I S = C - RNTI mod

[0683] mod

[0684] mod

[0685] where K represents K f . Or K t , or the product of K f and K t .

[0686] Of course, there can also be other ways, as long as (I S , I k , i) can be accurately determined, this solution is also applicable.

[0687] As can be seen from the above, the solution provided by the embodiments of the present application mainly involves:

[0688] (1) For the initial PUCCH resource set, expand the capacity by methods such as expanding its initial cyclic shift index set, using OCC scrambling, and expanding its PRB set (see Examples 1 - 4 for details).

[0689] (2) For the initial PUCCH resources with expanded capacity, determine the new cyclic shift index set, OCC, and PRB index by what means (see directions (1) and (2) within each example and specific methods A - F for details).

[0690] In summary, compared with the prior art, the capacity of the initial PUCCH resource set is very limited. When a large number of RedCap UEs access NR, the capacity of the existing initial PUCCH resources may not be sufficient to support multiple RedCap UEs that have not entered the RRC connected state to simultaneously send PUCCH. In this solution, without changing the basic framework of the existing initial PUCCH resource set, the capacity of the PUCCH is expanded, and the feedback delay increase, access delay elongation, and access failure risk of RedCap UEs are reduced.

[0691] The embodiment of the present application also provides a terminal device, as Figure 6 shown, including a memory 61, a transceiver 62, and a processor 63:

[0692] The memory 61 is used to store a computer program; the transceiver 62 is used to transmit and receive data under the control of the processor 63; the processor 63 is used to read the computer program in the memory 61 and perform the following operations:

[0693] Determine a target PUCCH resource from a first physical uplink control channel PUCCH resource set according to first information;

[0694] Use the transceiver 62 to send a PUCCH to a network device in the target PUCCH resource;

[0695] Wherein, the first information includes at least one of: a cell radio network temporary identifier C-RNTI corresponding to the terminal device, a synchronization signal block SSB index selected when initially accessing the network, a random access opportunity RO index selected when initially accessing the network, first frequency-domain physical resource block PRB position information, first control channel element CCE information, first PUCCH resource indication PRI information, and a first formula;

[0696] The first PRB position information is the PRB position information of a physical downlink shared channel PDSCH, the first CCE information is the CCE information of a physical downlink control channel PDCCH scheduling the PDSCH, the first PRI information is the extended PRI information of downlink control information DCI in the PDCCH scheduling the PDSCH, and the first formula is a formula for determining a PUCCH resource index after the terminal device enters a radio resource control RRC connected state;

[0697] The number of elements in the first category set corresponding to the first PUCCH resource set is greater than the number of elements in the first category set corresponding to the second PUCCH resource set, and / or, the number of the first category sets corresponding to the first PUCCH resource set is greater than the number of the first category sets corresponding to the second PUCCH resource set;

[0698] The first category set includes at least one of: an initial cyclic shift CS index set, an orthogonal mask OCC set, a time-domain resource set, and a frequency-domain resource set;

[0699] The second PUCCH resource set is a defined resource set.

[0700] In the embodiment of the present application, the terminal device determines a target PUCCH resource from a first physical uplink control channel PUCCH resource set according to first information, and sends a PUCCH to a network device in the target PUCCH resource, where the first information includes at least one of: a cell radio network temporary identity C-RNTI corresponding to the terminal device, a synchronization signal block SSB index selected when initially accessing the network, a random access occasion RO index selected when initially accessing the network, first frequency-domain physical resource block PRB position information, first control channel element CCE information, first PUCCH resource indication PRI information, and a first formula; the first PRB position information is the PRB position information of a physical downlink shared channel PDSCH, the first CCE information is the CCE information of a physical downlink control channel PDCCH scheduling the PDSCH, the first PRI information is the extended PRI information of downlink control information DCI in the PDCCH scheduling the PDSCH, and the first formula is a formula for determining a PUCCH resource index after the terminal device enters a radio resource control RRC connected state; the number of elements in the first category set corresponding to the first PUCCH resource set is greater than the number of elements in the first category set corresponding to the second PUCCH resource set, and / or, the number of the first category sets corresponding to the first PUCCH resource set is greater than the number of the first category sets corresponding to the second PUCCH resource set; the first category set includes at least one of: an initial cyclic shift CS index set, an orthogonal mask OCC set, a time-domain resource set, and a frequency-domain resource set; the second PUCCH resource set is a defined resource set; it can achieve expanding the capacity of the PUCCH without changing the basic framework of the existing initial PUCCH resource set, and using the expanded capacity for information transmission for the PUCCH, reducing risks such as increased feedback delay, increased access delay, and access failure caused by insufficient PUCCH capacity of the terminal, and well solving the problem that the terminal cannot access or the access delay is too large due to insufficient PUCCH capacity in the prior art.
