technical field

The present disclosure relates to the field of communication technologies, and in particular, to an information transmission method, device, terminal equipment, and network equipment.

Background technique

In the fifth-generation mobile communication (Fifth-generation, 5G) new radio (New Radio, NR) system, the terminal (User Equipment, UE) needs to transmit to the base station (gNB) through the Physical Uplink Control Channel (PUCCH) Uplink control information. For example, the UE sends a Hybrid Automatic Repeat reQuest-ACKnowledgment (HARQ-ACK) feedback information to the gNB according to whether it receives the Physical Downlink Shared Channel (PDSCH) sent by the gNB correctly or not, This information belongs to one type of uplink control information; specifically, the HARQ-ACK feedback information can be sent through the bearer of the PUCCH. However, the capacity of PUCCH is limited. Especially before the UE completes initial access and obtains UE-specific Radio Resource Control (Radio Resource Control, RRC) configuration, all UEs that have not obtained UE-specific RRC PUCCH configuration will share the same PUCCH resource set, and record the PUCCH resource The set is "initial PUCCH resource set". For the UE, the initial PUCCH resource set is determined through protocol pre-definition combined with gNB broadcast configuration instruction information.

In addition, at present, NR is about to support a reduced complexity (Reduced Capability, RedCap) UE (that is, a UE with reduced capability). An important application scenario of RedCap UE is industrial sensor network, so it is foreseeable that the number of RedCap UE may be huge. When a large number of RedCap UEs access the NR network at the same time, it may cause excessive access delay or even access failure due to insufficient capacity of the initial PUCCH resource set.

The content involved in the solutions provided by the embodiments of the present disclosure will be firstly introduced below.

In the related NR technology, the gNB indicates the index of a resource set through the broadcasted system information PUCCH common resource indication information (pucch-ResourceCommon). The initial PUCCH resource set (Table 1 is currently predefined).

Table 1: PUCCH resource sets before dedicated PUCCH resource configuration (PUCCH resource sets before dedicated PUCCH resource configuration)

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 format 1 used by the PUCCH of the initial PUCCH resource set, the first symbol (symbol) in a slot (slot) is symbol 10, and the number of symbols is 4, which is used to determine the physical resource block offset of the PUCCH frequency domain position (Physical Resource Block offset, PRB offset) (also

) is 0, and the set of available initial cyclic shift indexes (initial CS index) includes 2, which are {0,6}. in table 1 above

is the bandwidth of the uplink initial bandwidth part (Bandwidth Part, BWP).

In the above Table 1, the initial PUCCH resource set corresponding to any row configuration has only 16 PUCCH resources; and, for the PUCCH format 1, it is currently specified that the index of its Orthogonal Cover Code (OCC) is 0. The OCC with an index of 0 is a sequence of all 1s, and using the sequence of all 1s for scrambling is equivalent to performing scrambling without using any mask.

When the UE performs HARQ-ACK feedback on the PDSCH, it determines the resources of the PUCCH to be used in the following way:

1. The UE determines the PUCCH index (ie resource index)

Among them, N _CCE is the number of control channel elements (control channel element, CCE) included in the control resource set (CORESET) where the PDCCH used to schedule the PDSCH is located, and n _{CCE, 0} is the actual PDCCH that the UE is scheduled to receive the PDSCH. The index of the first CCE in the CCE, _ΔPRI is the value indicated by the "PUCCH resource indication field" in the downlink control information (Downlink Control Information, DCI) (carried in the PDCCH) that schedules the PDSCH, and the value range is 0 ~7. To sum up, the possible value range of r _PUCCH is 0-15. Note here that the formula symbols involved in this disclosure

Indicates that the value inside the symbol is rounded down.

2. The UE determines the physical frequency domain resource block (Physical Resource Block, PRB) position index and initial CS index of the PUCCH according to r _PUCCH :

(1) If

but:

1) The first physical resource block index of the first hop (hop1) of PUCCH is

The index of the first PRB of the second hop (hop2) is

It is the bandwidth of the uplink initial BWP. N _CS is the number of Initial CS indexes included in the initial cyclic shift set.

2) The Initial CS index is (that is, equal to) r _PUCCH mod N _CS , where N _CS is the number of Initial CS indexes contained in the initial cyclic shift set. The symbol mod represents a remainder operation, for example, r _PUCCH mod N _CS represents the remainder of r _PUCCH divided by N _CS .

(2) If

but:

1) The first PRB index of hop1 is

The index of the first PRB of hop2 is

2) The Initial CS index is (r _PUCCH -8) mod N _CS .

Still taking the initial PUCCH resource set as the row with index 3 in Table 1 as an example (the initial cyclic shift index set includes 2 elements at this time, so N _CS =2), assuming that the UE The "PUCCH resource indication field" of the CCE and DCI indicates that r _PUCCH = 5, because

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 =5mod2=1, that is, the Initial CS is 6 in {0,6}. Among them: '0' in {0,6} corresponds to index 0, and '6' corresponds to index 1.

In addition, at present, at the same time, the network device will only indicate one row in the above table 1, and the initial PUCCH resource set corresponding to this row contains 16 PUCCH resources, that is, all UEs that have not obtained UE-specific RRC PUCCH configuration before sharing For the 16 PUCCH resources, the capacity of the PUCCH cannot be increased by means such as OCC (the method in the related art is equivalent to not using OCC). Therefore, only 16 UEs at most can send the PUCCH in the same slot time.

When a large number of RedCap UEs access NR, the capacity of the initial PUCCH resource in the related art may not be enough to support multiple RedCap UEs that have not yet entered the RRC connection state to send PUCCH at the same time. This will increase the feedback delay of the RedCap UE, increase the access delay, and may even lead to access failure.

Based on the above, the embodiments of the present disclosure provide an information transmission method, device, terminal equipment, and network equipment to solve the problem in the related art that the terminal cannot access or the access delay is too large due to insufficient PUCCH capacity. Among them, the method, device, terminal device and network device are based on the same application idea, and since the principles of the method, device, terminal device and network device to solve problems are similar, the implementation of the method, device, terminal device and network device can be referred to each other, Repeated points will not be repeated.

The information transmission method provided by the embodiment of the present disclosure is applied to a terminal device, as shown in FIG. 2 , including:

Step 21: Determine the target PUCCH resource from the first physical uplink control channel PUCCH resource set according to the first information;

Step 22: Send the PUCCH to the network device in the target PUCCH resource; wherein, the first information includes: a Cell-Radio Network Temporary Identity (C-RNTI) corresponding to the terminal device, an initial The synchronization signal block (Synchronization Signal Block, SSB) index selected when accessing the network, the random access opportunity (Random Access Channel Occasion, RO) index selected when initially accessing the network, the first PRB position information, the first CCE information, The first PUCCH resource indication (PUCCH Resource Indication, PRI) information, and at least one item in the first formula; the first PRB position information is the PRB position information of the physical downlink shared channel PDSCH, and the first CCE information is the scheduling The CCE information of the physical downlink control channel PDCCH of the PDSCH, the first PRI information is the extended PRI information of the downlink control information DCI in the PDCCH scheduling PDSCH, and the first formula is that the terminal equipment enters the radio resource control RRC connection The formula for determining the PUCCH resource index after the state; the number of elements of the first category set corresponding to the first PUCCH resource set is greater than the number of elements of the first category set corresponding to the second PUCCH resource set, and/or, the first category set corresponding to the second PUCCH resource set The quantity of the first category set corresponding to a PUCCH resource set is greater than the quantity of the first category set corresponding to the second PUCCH resource set; the first category set includes: an initial cyclic shift CS index set, an orthogonal mask OCC set, At least one of a time domain resource set and a frequency domain resource set; the second PUCCH resource set is a defined resource set, for example, the second PUCCH resource set is the PUCCH resource set in Table 1 above.

Wherein, the PRI field represents the PUCCH resource indication field;

Regarding "the number of elements of the first category set corresponding to the first PUCCH resource set is greater than the number of elements of the first category set corresponding to the second PUCCH resource set, and/or, the number of elements of the first category set corresponding to the first PUCCH resource set The number of a category set is greater than the number of the first category set corresponding to the second PUCCH resource set" can be understood as: the capacity of the first PUCCH resource set will be greater than the capacity of the second PUCCH resource set;

The application scenario of this solution is illustrated below with an example.

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

As shown in Figure 4, the applicable scenario of this solution is illustrated (the terminal device is taken as user equipment UE, and the network device is taken as gNB (next generation B node (fifth generation mobile communication system base station)) as an example); among them, Multiple UEs including UE1 and UE2 initiate random access to the gNB to apply for wireless network connection services; the gNB receives a random access request from at least one UE and provides wireless services for it. Data interaction and transmission are performed between the gNB and UE1 and UE2 through wireless communication.

From the above, the network elements involved in this solution mainly include:

(1) Network equipment, such as base stations, gNB;

(2) Terminal equipment, such as user equipment, UE, RedCap UE.

The solutions provided by the embodiments of the present disclosure are described below with specific examples. A terminal device is taken as an example, and a network device is taken as an example of a base station.

Example 1

In this example, the first method is adopted: increasing the number of initial cyclic shift indexes in the PUCCH resource set to expand the capacity of the initial PUCCH resource set.

About expanding the capacity of the initial PUCCH resource set:

In the current configuration of all initial PUCCH resource sets (refer to Table 1 above), the available initial cyclic shift index sets (Set of initial CS indexes) are {0,3}, {0,4,8}, {0,6 } or {0,3,6,9}.

In this example, the 'Extended Set of initial CS indexes' is used. That is, in the initial PUCCH resource set, there is at least one line of configuration in which 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'. In particular, in this example, the number of indexes in the new Set is N _S times the number of indexes in the original Set (corresponding to the first expansion multiple or the second expansion multiple), and N _S is a positive integer greater than 1.

Specifically, for example, a new initial PUCCH resource set table can be pre-defined as shown in Table 2, wherein some of the Set of initial CS indexes are higher than the Set of initial CS in the original initial PUCCH resource set table (corresponding to Table 1 above). New configurations with many indexes, such as the Set of initial CS indexes corresponding to indexes 7 to 14.

Table 2

The above table 2 is just an illustration, and there are also other configurations with more initial cyclic displacement index numbers, such as extending {0,6} to {0,2,4,6,8,10}, which will not be described here limited.

After the initial PUCCH resource capacity is increased by using more initial cyclic shift index numbers, it is also necessary to consider how to indicate the extended PUCCH resource. Wherein, the PUCCH resource includes such dimensions as PRB position and initial cyclic shift index.

In this example, the method of indicating a new (initial cyclic shift index number increased) PUCCH resource mainly has two directions:

(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 resource according to the extended r′ _PUCCH .

Specifically, the r′ _PUCCH can be extended by the following methods:

A. According to the extension of C-RNTI;

The 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 extended initial PUCCH resource index r' _PUCCH .

Some possible approaches include:

or,

(SFN is the system frame number, specifically refers to the frame number of the system frame where the UE sends the PUCCH, or the system frame number of the PDSCH corresponding to the PUCCH, or the system frame number of the PDCCH that schedules the PDSCH. The introduction of SFN can make different time The index of the initial cyclic shift of the PUCCH is different, which is beneficial to the randomization of the interference of the UE to other cells); but it is not limited thereto.

In a word, the extended r′ _PUCCH can be determined according to the C-RNTI, and this solution is applicable.

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

In the initial access phase, UE will select 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 .

Some possible approaches include:

or,

But not limited to this.

In a word, the extended r′ _PUCCH can be determined according to the I _SSB or I _RO , and this solution is applicable.

C. According to the frequency domain PRB position expansion of PDSCH;

In this manner, the PRB index I _PRB of the PDSCH may optionally be the index of the first (ie, the lowest frequency) PRB of the PDSCH, or the index of the last (ie, the highest frequency) PRB of the PDSCH. The I _PRB is used to determine r' _PUCCH .

Some possible approaches include:

or,

But not limited to this. Among them, Floor(x) means to round down x, which is equivalent to

Ceil means to round up x, which is equivalent to

In a word, it only needs to determine the extended r' _PUCCH according to the I _PRB , and this solution is applicable.

D. According to the CCE extension of the PDCCH scheduling PDSCH;

The CCE index I _CCE of the PDCCH may optionally be the index of the first CCE of the PDCCH, or the index of the last PRB. It should be noted that unlike PDSCH, the first and last CCEs here are determined in a predefined manner, not necessarily the lowest or highest frequency CCEs.

Some possible approaches include:

But not limited to this.

In a word, the extended r′ _PUCCH can be determined according to the _ICCE , and this solution is applicable.

E. Extend according to the extended PRI information of the DCI in the PDCCH that schedules the PDSCH;

At present, the DCI for scheduling PDSCH received by the UE in the initial access phase includes a 3-bit PRI field, which is used to determine

Wherein, ΔPRI is an indication value of the _PRI field in the DCI.

In this method, the PRI field in DCI is extended from 3 bits to 3+x bits, where

UE can be based on the original formula

r' _PUCCH in the range of 0 to 2 ^4+x -1 is determined.

F. According to a specific formula (the formula for determining the _rPUCCH by the UE in the RRC_CONNECTED (connected) state, corresponding to the above-mentioned first formula) expansion;

At present, when the UE completes the initial access, it will enter the RRC connected state (that is, RRC_CONNECTED) state. The base station can configure UE-specific PUCCH resource sets for the UE, and can configure up to four PUCCH resource sets. Wherein, the first UE-specific PUCCH resource set may include R _PUCCH PUCCH resources. When R _PUCCH is greater than 8, r _PUCCH is determined according to the following formula:

For the extended initial PUCCH resource set, it is obvious that R _PUCCH >8. Therefore, in this manner, the above formula is directly reused to indicate r' _PUCCH . The p in the above formula represents the index of the CORESET, which is equivalent to p=0 in this manner.

Further, in direction (1), after determining the r' _PUCCH through the methods A to F above, the UE determines the PRB position index and (extended) initial CS index of the PUCCH according to the r' _PUCCH .

A possible method is:

(1) If

but:

1) The first physical resource block index of the first hop hop1 of PUCCH is

The index of the first PRB of the second hop hop2 is

2) The Initial CS index is r' _PUCCH mod(N _S ×N _CS ).

(2) If

but:

1) The first PRB index of the first hop hop1 is

The index of the first PRB of the second hop hop2 is

2) The Initial CS index is (r' _PUCCH -8) mod (N _S ×N _CS ).

In the above formula, a new parameter N′ _CS can also be used to represent N _S ×N _CS , and the two are equivalent.

There may also be other methods of determining the PRB and (extended) initial CS index according to the r' _PUCCH , and this solution is also applicable.

(2) The scope of the initial PUCCH resource index r _PUCCH is not extended, but the extended CS is determined on the basis of the PRB and CS resources of the PUCCH in the related art through an additional sub-index;

Specifically, in direction (2), it is often necessary to determine an initial cyclic shift sub-index (denoted as I _S ), and further determine the initial cyclic shift index under the extended initial PUCCH resource set according to the sub-index, Record it as I _new . Direction (2) and direction (1) essentially realize the indication of the extended initial PUCCH resource through additional information (such as C-RNTI, SSB index, etc.).

Specifically, in the direction (2), the following method can be used to indicate the specific PRB of the PUCCH after the initial cyclic shift index number is enlarged:

A. Determined according to C-RNTI;

1) First, it is necessary to obtain an initial cyclic shift sub-index according to the C-RNTI (denoted as I _S , corresponding to the above-mentioned target index, and the same applies to the following calculation methods):

I _S can be calculated according to the formula: I _S =C-RNTI mod N _S (as mentioned above, the number of indexes in the new Set is N _S times the number of indexes in the original Set);

Alternatively, I _S can be calculated according to the formula: I _S =(C-RNTI+SFN) mod N _S ;

Or in other ways, as long as I _S can be uniquely determined by the C-RNTI and I _S ={0,1,...,N _S -1}.

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, the same applies to the following calculation methods), and I _S , determine the initial Circular shift index I _new (corresponding to the above-mentioned final index, the same applies to the following calculation methods). For example:

According to the formula I _new =I× _NS +I _S , determine the initial cyclic shift index under the extended initial PUCCH resource set.

A specific example is: For example, suppose 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 }, expansion factor N _S =3, sub-index I _S =0, 1, 2; if I = 0, I _S = 1 obtained through the above calculation or instruction, then I _new = 0×3+1 = 1; then For example, if I=1, I _S =2, then I _new =1×3+2=5.

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 the index in the new set Subset, I = 0 corresponds to the subset {0, 2, 4}, I = 1 corresponds to the subset {6, 8, 10}, and I _S indicates which specific index in a certain subset is used as 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, and I=0 corresponds to the starting point being {0, 0 of 2,4,6,8,10}, I=1 corresponds to 6 whose starting point is {0,2,4,6,8,10}, and I _S indicates that under a certain starting point, it is necessary to offset The initial cyclic shift index under the new collection is obtained by shifting several indexes.

B. Determined according to the SSB index or RO index selected during initial access;

First, an initial cyclic shift sub-index (denoted as I _S ) needs to be obtained according to the SSB index I _SSB or RO index I _RO selected by the UE in the initial access phase:

Similar to the above case of A, 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 a method similar to the above-mentioned A to determine I _new according to I _S and I.

C. Determine the frequency domain PRB position according to the PDSCH;

In this manner, 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 the PDSCH. in:

The PRB index I _PRB of the PDSCH may optionally be the index of the first (ie, the lowest frequency) PRB of the PDSCH, or the index of the last (ie, the highest frequency) PRB of the PDSCH.

Then, similar to the case of A above, it can be based on formula 1: I _S = I _PRB mod N _S , or formula 2:

or other formulas to determine I _S , and then use a method similar to the above-mentioned A to determine I _new according to I _S and I, which will not be repeated here. in,

Indicates the downlink BWP bandwidth for PDSCH transmission.

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

D. Determine according to the CCE of the PDCCH that schedules the PDSCH;

In this manner, 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 that schedules the PDSCH.

The CCE index I _CCE of the PDCCH may optionally be the index of the first CCE of the PDCCH, or the index of the last PRB. It should be noted that unlike PDSCH, the first CCE and the last CCE here are not necessarily the lowest or highest frequency CCEs.

Then similar to the case of A above, I _S can be determined according to formula 1: I _S = I _CCE mod N _S , or formula 2: I _S = floor(I _CCE /ceil( _NCCE / _NS )), or other formulas , and then use a method similar to the above-mentioned A to determine I _new according to I _S and I, which will not be repeated here. Wherein, N _CCE represents the number of CCEs included in the control resource set (CORESET) where the PDCCH used to schedule the PDSCH is located.

E. Determine according to the extended PRI information of the DCI in the PDCCH scheduling the PDSCH;

Wherein, ΔPRI is the indicated value of the _PRI field.

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

1) 3 bits of the 3+x bits still indicate the _ΔPRI in the range of 0 to 7 according to the current method, so that the UE can

Determine the r _PUCCH in the range of 0 to 15, and further determine I; and the x bits in the 3+x bits (can indicate 0, 1, 2, ..., 2 ^x -1) indicate I _S , and use the method in A above OK I _new , where

In a word, the capacity of the initial PUCCH resource set can be expanded by increasing the number of initial cyclic shift indexes in the PUCCH resource set. Specifically, the above methods A-E may be used to determine which initial cyclic shift index (in the expanded initial PUCCH resource set) to use.

Further, considering how the UE judges that the new initial PUCCH resource set (extended set) and/or the original PUCCH resource set (before extended set) should be used; the embodiments of the present disclosure provide the following content:

This section 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, RedCap UE can use the appropriate initial PUCCH resource set in the following ways:

(1) Pre-defined mode (corresponding to the above-mentioned terminal device belonging to the first type of pre-defined terminal). For example, it can be stipulated that: RedCap UEs, or UEs that support PUCCH expansion, use the extended (new) initial PUCCH resource set, and non-RedCap UEs (non-RedCap UEs) or UEs that do not support PUCCH expansion still use the original initial PUCCH resource set by default . This method is simple to implement, and can also make the network system have better compatibility.

(2) A mode of semi-static indication (corresponding to receiving the above-mentioned system information broadcasted by the network device). For example, the base station may broadcast a system message (such as a system information block SIB1), and in the SIB1 indicate whether the initial PUCCH resource set used by the RedCap UE (or a UE supporting PUCCH expansion) is a new set or an original set. This method has better flexibility than the predefined way.

(3) A manner of DCI indication (corresponding to receiving the above-mentioned downlink control information DCI sent by the network device). For example, in the DCI that schedules the UE to receive the PDSCH (such as the DCI transmitted by the scheduling message Msg4), 1 bit of information is used to indicate the RedCap UE (or the UE that supports PUCCH expansion) to use the initial PDSCH feedback in the PUCCH. Whether the PUCCH resource set is a new set or an original set. The 1-bit information can be obtained by further extending the PRI field, or can be obtained by using redundant bits not used in the current DCI. This method has the highest flexibility.

It is explained here that the extended (new) initial PUCCH resource set can be realized 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 Setof 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; no limitation is made here.

Example 2

In this example, method 2 is adopted: using OCC (Orthogonal Cover Code, orthogonal mask) to scramble the PUCCH to expand the capacity of the initial PUCCH resource set.

The basic principle of OCC scrambling is: after the transmitting end scrambles the sequences with mutually orthogonal OCC codes, the receiving end can distinguish the sequences of different OCC codes by means of coherent detection. At present, in NR, the index of the OCC of the PUCCH that specifies the initial PUCCH resource set is 0, and the OCC with the index of 0 is a sequence of all 1s. Using the OCC sequence of all 1s for scrambling is actually equivalent to not using any OCC for scrambling. .

About expanding the capacity of the initial PUCCH resource set:

In this example, different OCC codes are used to scramble the PUCCH in the initial PUCCH resource set. The same PUCCH scrambled by multiple orthogonal OCC codes can be detected and distinguished by the base station even if it is sent using the same time-frequency resource, thereby increasing the capacity of the PUCCH.

It should be pointed out that this example using OCC is applicable to PUCCH format 1.

In this solution, there is no restriction on the specific OCC code used, as long as it is an orthogonal code with a suitable length. A possible example is to use the currently specified orthogonal codes used by PUCCH format 1 (usually only used in non-initial PUCCHs):

Table 3: Orthogonal sequences of PUCCH format 1 (Orthogonal sequences

for PUCCH format 1) (m in the formula here represents the mth number in the sequence, and φ(m) represents the value of the mth number in the sequence)

The PUCCH in the initial PUCCH resource set can be scrambled by using the OCC code specified in the above table.

A concrete example:

Assuming that the initial PUCCH resource set is configured as configuration index 7 of Table 1, the format of the initial PUCCH is PUCCH format 1, and the time domain length is 10 Orthogonal Frequency Division Multiplexing (OFDM) symbols; due to the initial PUCCH Intra-slot frequency hopping must be used, and the time domain length of each hop is half of the total length, so it is 5 OFDM symbols, so OCC corresponds to the above table 3

In the row of , there are 5 mutually orthogonal OCC codes at this time, which are

row, the code whose index is i=0, 1, 2, 3, 4 is equivalent to extending the original OCC code

times. These 5 OCC codes can be used to scramble a PUCCH with a length of 10 OFDM symbols (and frequency hopping within a slot).

Regarding how to indicate the extended PUCCH resources; specifically, what is the index i of the OCC that the UE should use, similar to example 1, there are two possible directions:

Direction (1) is to extend the initial PUCCH resource index to r' _PUCCH , and determine the PUCCH resource (including OCC besides PRB and initial CS) according to the extended r' _PUCCH . In this direction, for how to determine r' _PUCCH , refer specifically to the manner of determining r' _PUCCH in Example 1 (for example, according to the C-RNTI), and the method is the same. Need to pay attention to use

(that is, the expansion multiple of the OCC index) replaces _NS (the expansion multiple of the initial cyclic shift index) in Example 1. details as follows:

A. According to the extension of C-RNTI;

Some possible approaches include:

or,

Some possible approaches include:

or,

But not limited to this.

C. According to the frequency domain PRB position expansion of PDSCH;

Some possible approaches include:

or,

Ceil means to round up x, which is equivalent to

D. According to the CCE extension of the PDCCH scheduling PDSCH;

Some possible approaches include:

But not limited to this.

Wherein, ΔPRI is an indication value of the _PRI field in the DCI.

In this method, the PRI field in DCI is extended from 3 bits to 3+x bits, where

UE can be based on the original formula

r' _PUCCH in the range of 0 to 2 ^4+x -1 is determined.

When determining the PRB position index, initial CS index and OCC index i of the PUCCH according to the r′ _PUCCH , a feasible method is:

(1) Calculate the intermediate variable r″ _PUCCH = r′ _PUCCH mod 16;

(2) calculation

(3) If

but:

1) The first physical resource block index of the first hop hop1 of PUCCH is

The index of the first PRB of the second hop hop2 is

2) The Initial CS index is r″ _PUCCH mod N _CS .

(4) If

but:

1) The first PRB index of the first hop hop1 is

The index of the first PRB of the second hop hop2 is

2) The Initial CS index is (r″ _PUCCH -8) mod N _CS .

There may also be other methods of determining the PRB, initial CS index, and OCC index according to the r' _PUCCH , and this solution is also applicable.

In this example, direction (2) does not extend the range of the initial PUCCH resource index r _PUCCH , but needs to determine an OCC sub-index (that is, i); direction (2) and direction (1) essentially use additional information (such as C-RNTI, SSB index, etc.) to realize the indication of the extended initial PUCCH resources.

The specific methods for determining the OCC index i under direction (2) may include:

A. Determined according to C-RNTI;

Referring to the method for determining I _S in Example 1, it can also be used to determine the OCC index i. Need to pay attention to use

(that is, the OCC index expansion multiple) replaces _NS (initial cyclic shift index expansion multiple) in Example 1, and it is no longer necessary to calculate I _new , but to calculate i.

For example, by

or

Calculate i; or other methods, as long as i can be uniquely determined by C-RNTI and

That's it.

(that is, the total number of OCC indexes) replaces _NS (the total number of initial cyclic shift indexes) in Example 1, and it is no longer necessary to calculate I _new , but to calculate i. specific:

It is necessary to obtain an OCC index (denoted as i) according to the SSB index I _SSB or RO index I _RO selected by the UE in the initial access phase:

Similar to the situation of A above, according to the formula

or

and so on to determine i.

C. Determine the frequency domain PRB position according to the PDSCH;

In this manner, 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. in:

Then similar to the situation of A above, according to formula 1:

or formula 2:

or other formulas to determine i. in,

Indicates the downlink BWP bandwidth for PDSCH transmission.

The difference between the effects of the above two formulas (Formula 1 and Formula 2) can be similarly seen in Figure 5, where it is assumed

Formula 1 corresponds to: the index i changes cyclically with the increase of I _PRB , and Formula 2 corresponds to: dividing the PRB as a whole into

area, i depends on which area the PRB index of the PDSCH is in. DL initial BWP in the figure represents the downlink initial bandwidth part.

D. Determine according to the CCE of the PDCCH that schedules the PDSCH;

In this manner, the PUCCH resource (such as i index) used by the UE for HARQ-ACK feedback for a certain PDSCH is determined according to the CCE index of the PDCCH that schedules the PDSCH.

Then similar to the situation of A above, according to formula 1:

or formula 2:

or other formulas to determine i. Wherein, N _CCE represents the number of CCEs included in the control resource set (CORESET) where the PDCCH used to schedule the PDSCH is located.

Wherein, ΔPRI is the indicated value of the _PRI field.

Determine the r _PUCCH ranging from 0 to 15, 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) indicate i ;in

In a word, different OCC codes can 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 A-E may be used to determine which OCC code to use.

It is explained here that the relevant content in Example 1 can be adaptively adjusted and applied to the solution in Example 2, so details are not repeated here.

In addition, in this example, since the initial CS field is not extended, there is no need to calculate I _new as in Example 1.

Example 3

In this example, the capacity of the initial PUCCH resource set is expanded by way three: increasing the number of usable PRBs in the initial PUCCH resource set and/or time-domain symbol groups.

Currently, through

Determine r _PUCCH (the value range is 0 to 15, a total of 16 states), and then determine the PRB position of the PUCCH according to the index number N _CS in the initial cyclic shift index set (such as

) and an initial cyclic shift index (such as r _PUCCH mod N _CS ).

In short, currently, in the frequency domain, the number of PRBs used by the initial PUCCH resource is very limited. For example, if N _CS =4, only 4 PRBs are actually used; if N _CS =2, only 8 PRBs are actually used. In the time domain, there is only one symbol group used in each slot, that is, a symbol group starting from the first symbol and continuing 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 only occupies the last 2 symbols of a slot in the time domain (starting from symbol 12 and continuing for 2 symbols).

Table 4

About expanding the capacity of the initial PUCCH resource set:

In this example, in the frequency domain, the capacity of the initial PUCCH set can be expanded by increasing the number of usable PRBs in the initial PUCCH resource set to the original K _f times (K _f is an integer greater than 1); PRB resource extension in domain dimension can be used for all initial PUCCH resource set configurations.

In the time domain, the initial PUCCH resource set may also be extended to K _t symbol groups from one slot including only one symbol group (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 configuration in which the number of PUCCH symbols does not exceed 7.

Table 5 below shows an example of extending time-domain resources. For the initial PUCCH resource configurations 0-6, by adding an optional value of the first symbol in a slot, the time-domain resources are expanded by K _t = 2 times. Therefore, these configurations The PUCCH resource is also expanded by 2 times.

table 5

In this example, only frequency domain resources may be extended, only time domain resources may be extended, or both frequency domain and time domain resources may be extended. When both the frequency domain and the time domain are extended, the extended resource in the time-frequency domain can be jointly encoded, and can be identified by a unified index, or can be identified by an index in the frequency domain and time domain respectively, which are equivalent , is not limited here.

Regarding how to indicate the extended PUCCH resources, frequency domain extension is taken as an example to introduce below. The cases of time domain extension and time-frequency domain extension are similar to the case of frequency domain extension.

Specifically, the index of the PRB that the UE should use (denoted as

), similar to Example 1, there are two feasible directions:

Direction (one) is to extend the initial PUCCH resource index to r' _PUCCH , and determine the PUCCH resource (PRB and initial CS) according to the extended r' _PUCCH . In this direction, for how to determine r' _PUCCH , refer specifically to the manner of determining r' _PUCCH in Example 1 (for example, according to the C-RNTI), and the method is the same. It should be noted that K _f (that is, the expansion multiple of the number of available PRBs in the initial PUCCH resource set) is used instead of _NS (the expansion multiple of the initial cyclic shift index) in Example 1. specific:

A. According to the extension of C-RNTI;

Some possible approaches include:

or,

Some possible approaches include:

or,

But not limited to this.

C. According to the frequency domain PRB position expansion of PDSCH;

Some possible approaches include:

or,

Ceil means to round up x, which is equivalent to

D. According to the CCE extension of the PDCCH scheduling PDSCH;

Some possible approaches include:

But not limited to this.

Wherein, ΔPRI is an indication value of the _PRI field in the DCI.

In this method, the PRI field in DCI is extended from 3 bits to 3+x bits, where

UE can be based on the original formula

r' _PUCCH in the range of 0 to 2 ^4+x -1 is determined.

Furthermore, when the number of PRBs increases to the original K _f times, how to "determine the PRB index according to r' _PUCCH

One possible method is:

(1) If

but:

1) The first physical resource block index of the first hop hop1 of PUCCH is

The index of the first PRB of the second hop hop2 is

It is the bandwidth of the uplink initial BWP.

2) The Initial CS index is r' _PUCCH mod N _CS .

(2) If

but:

1) The first PRB index of the first hop hop1 is

The index of the first PRB of the second hop hop2 is

2) The Initial CS index is (r' _PUCCH -8×K _f ) mod N _CS .

There may also be other methods of determining the PRB and initial CS index according to the r' _PUCCH , and this solution is also applicable.

In this example, direction (two) does not extend the range of the initial PUCCH resource index r _PUCCH , but needs to determine a sub-index of a PRB (denoted as I _k ); direction (two) and direction (one) are essentially through additional The information (such as C-RNTI, SSB index, etc.) realizes the indication of the extended initial PUCCH resource.

Specifically, in the direction (2), the following method can be used to indicate the specific PRB of the PUCCH after the number of PRBs is enlarged:

A. Determined according to C-RNTI;

(1) Refer to Method A of Example 1. First, a sub-index of a PRB (denoted as I _k ) needs to be obtained according to the C-RNTI:

I _k can be calculated according to the formula: I _k =C-RNTI mod K _f ; or,

I k 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 system where the PDSCH corresponding to the PUCCH is located The frame number, or the system frame number where the PDCCH scheduling the PDSCH is located.

Or in other ways, as long as I _k can be uniquely determined by the C-RNTI and I _k = {0, 1, ..., K _f -1}.

(2) Then, according to the formula

or

(Here, take the first hop of PUCCH frequency hopping as an example, and the second hop is similar), determine the new PRB index

Regarding the second hop of PUCCH frequency hopping, for example: according to the formula

or

Determine the new PRB index

Referring to the method for determining I _S in Example 1, it can also be used to determine the sub-index I _k of the PRB. Then similar to the method A above, the index of the PRB can be determined

The determination of the sub-index I _k is specific:

According to the SSB index I _SSB or RO index I _RO selected by the UE in the initial access phase, an initial cyclic shift sub-index (denoted as I _k ) needs to be obtained:

Similar to the above case of A, 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 .

C. Determine the frequency domain PRB position according to the PDSCH;

The determination of the sub-index I _k is specific:

In this method, the PUCCH resources used by the UE for HARQ-ACK feedback for a certain PDSCH (such as

index) is determined according to the PRB index of the PDSCH. in:

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 . in,

Indicates the downlink BWP bandwidth for PDSCH transmission.

The effect difference of the above two formulas (Formula 1 and Formula 2) can be similarly referred to in FIG. 5 , where it is assumed that K _f =4. Formula 1 corresponds to: the index I _k changes cyclically with the increase of I _PRB , and Formula 2 corresponds to: dividing the PRB into K _f regions as a whole, and I _k depends on which region the PRB index of the PDSCH is in. DL initial BWP in the figure represents the downlink initial bandwidth part.

D. Determine according to the CCE of the PDCCH that schedules the PDSCH;

The determination of the sub-index I _k is specific:

index) is determined according to the CCE index of the PDCCH that schedules the PDSCH.

Then similar to the case of A above, I _k can be determined according to formula 1: I _k = I _CCE mod K _f , or formula 2: I _k = floor(I _CCE /ceil( _NCCE /K _f )), or other formulas . Wherein, N _CCE represents the number of CCEs included in the control resource set (CORESET) where the PDCCH used to schedule the PDSCH is located.

Regarding the determination of the sub-index I _k , specifically:

Wherein, ΔPRI is the indicated value of the _PRI field.

Determine the r _PUCCH ranging from 0 to 15, and further determine the initial PRB index (corresponding to the above initial index); and the x bits in the 3+x bits (can indicate 0, 1, 2, ..., 2 ^x -1) indicate I _k , where

In a word, the capacity of the initial PUCCH resource set can be expanded by increasing the number of usable PRBs in the PUCCH resource set. Specifically, at least one of the above methods A-E may be used to determine the index of the expanded PRB.

It is explained here that the relevant content in Example 1 can be adaptively adjusted and applied to the solution in Example 3, and details are not repeated here.

Example 4

This example is only for illustration, and the methods in the above examples 1-3 can be used in combination.

For example, the PUCCH capacity can be extended by simultaneously "extending the initial cyclic shift index" and "using OCC for scrambling". If the initial cyclic shift index set is extended by N _S times, and the OCC code used is extended by

times, the final PUCCH capacity is expanded by

times.

In the case of combined use, the method in the above examples can still be used to determine the resources of the PUCCH after capacity expansion.

Take the determination of sub-indexes (I _S , I _k , i, etc.) according to at least one method in AE in the above example as an example, when using 2 (or 3) methods to expand the initial PUCCH capacity, you can choose from AE Two (or three) different methods are used in combination to obtain sub-indices respectively, and further determine at least one of a new initial cyclic shift index, an OCC index, and a PRB index.

For another example, multiple different sub-indices (I _S , I _k , i) can be obtained by using the same method in AE. Taking the need to obtain three sub-indices as an example, using C-RNTI as an example, (I _S , I _k , i) can be respectively obtained according to the same C-RNTI according to the following formula:

Here, K represents K _f . Either K _t , or the product of K _f and K _t .

Of course, other methods are also possible, as long as (I _S , I _k , i) can be accurately determined, this solution is also applicable.

As can be seen from the above, the solutions provided by the embodiments of the present disclosure mainly involve:

(1) For the initial PUCCH resource set, expand the capacity by extending its initial cyclic shift index set, using OCC scrambling, expanding its PRB set, etc. (see examples 1-4 for details).

(2) For the initial PUCCH resource with expanded capacity, how to determine the new cyclic shift index set, OCC and PRB index (see directions (1) (2) and specific methods A-F in each example for details).

In summary, compared with related technologies, the capacity of the initial PUCCH resource set is very limited. When a large number of RedCap UEs access NR, the capacity of the initial PUCCH resources in related technologies may not be sufficient to support multiple RedCap UEs that have not yet entered the RRC connection state. Send PUCCH at the same time; this solution expands the capacity of PUCCH without changing the basic framework of the initial PUCCH resource set in related technologies, and reduces the risk of RedCap UE's feedback delay increase, access delay becoming longer, and access failure .
