Detailed ways

In order to facilitate the understanding of the embodiments of the present invention, the PUCCH format (PUCCH format, PF) is first introduced below:

The PUCCH format includes: PUCCH format 0-4, a total of 5 types of PUCCH formats, of which the design features of each PUCCH format are shown in Table 1.

Table 1:

The number of demodulation reference signal (Demodulation Reference Signal, DMRS) symbols of PUCCH format 1 (PF1) is shown in Table 2.

Table 2:

Among them, it is the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols of PF1, which represents the number of symbols of DMRS resources or the DMRS in each hop when frequency hopping in the time slot is enabled. Symbol number.

The Orthogonal Cover Code (OCC) sequence of PF1 data symbols and DMRS symbols is shown in Table 3:

table 3:

Indicates the number of data or DMRS symbols, and i is the index of the OCC sequence.

For PF2, there is a DMRS on every symbol.

For PF3, PF4, the symbol positions occupied by DMRS in PUCCH are shown in Table 4.

Table 4:

The PUCCH repeated transmission in the prior art only supports the transmission of the same PUCCH format in multiple slots or sub-slots, and the number of symbols of the same PUCCH resource. Under some slot or sub-slot uplink and downlink configurations, it leads to uplink transmission. Resources cannot be fully utilized. As shown in Figures 1a and 1b:

In Figure 1a, the previous slot is a special slot. If PUCCH repeated transmission is performed in the unit of slot, the specific symbols (10-13) in the figure cannot be used for PUCCH repeated transmission, resulting in insufficient number of symbols in the slot. , Cannot be used for PUCCH transmission.

In Figure 1b, the previous slot is a special slot. If PUCCH transmission is performed in sub-slot units, the part of the specific symbol (0-2) in the third or fourth sub-slot in the figure cannot be used for PUCCH Transmission, the reason is to ensure that the PUCCH resources (uplink symbols 10-13) in the second sub-slot maintain the same starting symbol position and number of symbols.

Due to the foregoing reasons, in the case of repeated PUCCH transmission, uplink resources cannot be fully utilized for PUCCH transmission, which reduces resource utilization and PUCCH coverage performance.

Referring to FIG. 3, an embodiment of the present invention provides a method for repeated PUCCH transmission. The method is executed by a terminal, and includes: step 301 and step 302.

Step 301: Determine the first parameter of PUCCH;

Step 302: Perform PUCCH transmission in a first time resource according to the first parameter, and the first time resource is used for repeated PUCCH transmission.

It can be understood that the first time resource is a time slot or a sub-slot, but of course it is not limited to this;

The first parameter may include one or more of the following: (1) physical uplink control channel resource location; (2) resource block (Resource Block, RB) number, (3) orthogonal code, (4) PUCCH format; (5) The number of symbols used for PUCCH transmission.

Wherein, for example, the first time resources used for PUCCH repeated transmission may include at least two, and the at least two first time resources may include one of the following:

(1) At least two time slots, such as time slot 1, time slot 2, time slot 3, and time slot 4. It should be understood that the number of time slots used for PUCCH repeated transmission is not limited;

(2) At least two sub-slots, such as sub-slot 1, sub-slot 2, sub-slot 3, and sub-slot 4. It is understandable that the number of sub-slots used for PUCCH repeated transmission is not limited;

(3) At least one time slot and at least one sub-slot, such as time slot 1, sub-slot 1, time slot 2, and sub-slot 2. It should be understood that the time slot and sub-slot used for PUCCH repeated transmission are not limited. quantity.

It can be understood that the sub-slot is a continuous symbol in a slot, and the number of symbols in the sub-slot is less than the number of symbols in the slot. For example, the time slot includes symbols 0-13, and the sub-slot includes symbols 0-6.

For example, four PUCCH repeated transmissions are performed through slot1, sub-slot1, slot2, and sub-slot2. The first parameter of PUCCH repeated transmission in slot1 can be the same as the first parameter of PUCCH repeated transmission in sub-slot1. The first parameter for PUCCH repeated transmission or the first parameter for PUCCH repeated transmission in sub-slot 2 may be different, or the first parameter for PUCCH repeated transmission in slot 1 may be different from the first parameter for PUCCH repeated transmission in slot 2. The first parameter of PUCCH repeated transmission in sub-slot1 is different from the first parameter of PUCCH repeated transmission in sub-slot2, that is, the resource of four PUCCH transmissions in slot1, sub-slot1, slot2, and sub-slot2. The size can be different. To avoid the problem that PUCCH resources in different slots or sub-slots are required to be the same for PUCCHs that are repeatedly transmitted.

In some embodiments, step 301 includes: determining the first parameter of the PUCCH according to the number of available symbols of the first time resource.

For example, the UE determines the PUCCH format according to the number of available symbols (symbol) of each slot or sub-slot. The above-mentioned number of available symbols can also be referred to as the number of symbols available for PUCCH transmission, such as

Express.

Solution (1): If

The UE uses PF0 for PUCCH transmission, otherwise the UE uses PF1 for PUCCH transmission.

Optionally, in _{the case of O UCI} ≤ 2, use this scheme (1) to determine the PUCCH format;

Solution (2): If

The UE uses PF2 for PUCCH transmission, otherwise the UE uses PF3 or PF4 for PUCCH transmission.

Optionally, in _{the case of O UCI} > 2, use this scheme (2) to determine the PUCCH format.

Among them, O _UCI is a bit of at least one of Hybrid Automatic Repeat reQuest Acknowledgement (Hybrid Automatic Repeat reQuest Acknowledgement, HARQ-ACK), Channel State Information (CSI) and Uplink Scheduling Request (SR) Or the sum of the number of bits of at least two of HARQ-ACK, CSI, and SR, such as the sum of the number of bits of HARQ-ACK and CSI, or the sum of the number of bits of HARQ-ACK, CSI, and SR.

It should be noted that N1 and N2 in the above-mentioned scheme 1 and scheme 2 may be the same or different, and the values of N1 and N2 are not specifically limited in the embodiment of the present invention.

It is understandable that the method of determining the time domain resource location, frequency domain resource location, RB number, orthogonal code or the number of symbols used for PUCCH transmission based on the number of available symbols of the first time resource is similar to this, and will not be described here. .

In other embodiments, step 301 includes: determining the first parameter of the PUCCH according to the number of symbols transmitted by the PUCCH of the first time resource, where the number of symbols transmitted by the PUCCH

Less than or equal to the number of available symbols of the first time resource

For example, the number of symbols transmitted by the UE according to the PUCCH in each slot or sub-slot

Determine the first parameter of PUCCH, where

In some embodiments, step 302 includes: performing PUCCH transmission on part of the available symbols of the first time resource according to the first parameter.

For example, in slot or sub-slot

Before or after

PUCCH transmission is performed on two symbols, where,

Less than

In other embodiments, step 301 includes: performing PUCCH transmission on all available symbols of the first time resource according to the first parameter.

That is, the UE is

PUCCH transmission is performed in each symbol.

In other embodiments, step 302 includes: if the number of available symbols in the first time resource is less than the number of symbols in the PUCCH resource, performing PUCCH transmission on the available symbols in the first time resource.

For example, if the number of available symbols in a slot or sub-slot

Less than the number of symbols for PUCCH resources

Then the UE performs PUCCH transmission in the available symbols in a slot or sub-slot.

Optionally, the number of symbols of the PUCCH resource

It is configured on the network side; or, the number of symbols of the PUCCH resource

Is the maximum number of symbols of PUCCH resources in the PUCCH resource set, that is, the number of symbols of PUCCH resources

Is the number of symbols of the PUCCH resource with the most or least number of symbols in the PUCCH resource set; or, the number of symbols of the PUCCH resource

The symbol number of the resource is the symbol number of the PUCCH resource determined in the complete first-time resource (complete slot or sub-slot).

A complete slot or sub-slot means that all symbols can be used for PUCCH transmission.

In some embodiments, the UE may perform PUCCH transmission in the following manner:

Method 1: PUCCH transmission is performed through rate matching;

Method 2: PUCCH transmission is carried out by means of Puncture.

For example, the first N symbols in a punch slot or sub-slot,

Example 1, in

Before

PUCCH transmission is performed on the last N symbols of the symbols;

Example 2, in

After

in,

Represents the number of symbols of PUCCH resources,

Represents the number of available symbols for the first time resource.

In some embodiments, the method further includes: the UE determining an orthogonal cover code sequence.

Exemplarily, the manner in which the UE determines the orthogonal cover code sequence includes one or more of the following:

(1) Determine the orthogonal cover code sequence according to the number of symbols of the PUCCH resource configured on the network side and the orthogonal cover code index (OCC index);

Further, the N elements in the orthogonal cover code sequence are not used, for example, the first N elements in the orthogonal cover code sequence are not used, or the last N elements in the orthogonal cover code sequence are not used. The value of N in the N elements is not specifically limited;

(2) Determine the orthogonal cover code sequence according to the number of symbols used for PUCCH transmission;

(3) Determine the orthogonal cover code sequence according to the number of symbols used for PUCCH transmission and the orthogonal cover code index value.

Optionally, the foregoing orthogonal cover code index is a predefined index value.

In some embodiments, the UE may perform PUCCH transmission in the following manner:

If the first time resource includes multiple PUCCH resources, PUCCH transmission is performed through the PUCCH resource that meets the preset condition;

Wherein, the preset conditions include one or more of the following:

(1) The number of symbols of PUCCH resources

Less than or equal to the number of available symbols for the first time resource

Further, if there are at least two PUCCH resources that satisfy the preset condition (1), PUCCH transmission is performed through the PUCCH resource with the largest or smallest number of symbols among the at least two PUCCH resources.

(2) The start symbol of the PUCCH resource is the start symbol of the available symbols of the first time resource;

(3) The start symbol of the PUCCH resource is the symbol after the start symbol of the available symbols of the first time resource.

In some embodiments, the method further includes:

The number of resource blocks of the PUCCH resource is determined according to the number of symbols of the PUCCH resource used for PUCCH transmission.

For example, use the following formula to obtain the resource block number of PUCCH resources:

Among them, M is the number of resource blocks;

Is the number of subcarriers used to transmit uplink control information in each resource block;

Is the number of symbols for transmitting uplink control information among the number of symbols available for PUCCH transmission in the first time resource;

Q _m represents the modulation method;

r is the code rate, for example, r can be the maximum code rate configured by the network;

O _UCI is the number of bits in at least one of HARQ-ACK, CSI and SR, or the sum of the number of bits in at least two of HARQ-ACK, CSI and SR;

O _CRC cyclic redundancy check bit number.

Optionally, if M is the maximum number of RBs corresponding to the PUCCH format and still cannot satisfy the above inequality, then M RBs are used for PUCCH transmission, that is, the number of resource blocks of the PUCCH resource may be the maximum number of resource blocks corresponding to the PUCCH format.

In the embodiment of the present invention, the available symbols include one or more of the following:

(1) Flexible symbols or uplink symbols;

(2) The first symbol, which is not indicated as a downlink symbol or a flexible symbol by a slot format indicator (Slot Format Indicator, SFI) transmitted by a physical downlink control channel (Physical Downlink Control Channel, PDCCH);

(3) The second symbol, the second symbol is a flexible symbol, and the terminal does not detect the PDCCH indicated by the transmission slot format configured by the network;

(4) The third symbol, the third symbol does not overlap the fourth symbol in the time domain, and the fourth symbol includes one or more of the following: downlink physical signal, symbol received by downlink physical channel, uplink physical signal And symbols sent by the uplink physical channel, the uplink physical channel and/or uplink physical signal, the downlink physical signal and/or the downlink physical channel and the physical uplink control channel belong to the same serving cell or different serving cells.

Among them, the downlink physical signal may include one or more of the following: synchronization signal block, physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) and channel state information reference signal (Channel State Information-Reference Signals, CSI-RS); uplink; The physical signal may include one or more of the following: physical random access channel (Physical Random Access Channel, PRACH), uplink sounding reference signal (Sounding Reference Signal, SRS), and PUCCH.

In this way, in the case of repeated PUCCH transmission, the terminal can use different first parameters in multiple first time resources (slot or sub-slot) for PUCCH transmission, so that the terminal can make full use of PUCCH resources and increase PUCCH resources The utilization rate and PUCCH coverage performance.

The following will be introduced in conjunction with Embodiment 1, Embodiment 2, Embodiment 3, and Embodiment 4.

The network can configure the UE to perform PUCCH repeated transmission in a slot or a sub-slot. The sub-slot is a continuous symbol in a slot, and the number of symbols in the sub-slot is less than the number of symbols in the slot.

Example one:

If the network side is configured for the UE to perform PUCCH repeated transmission in multiple slots or sub-slots. The number of symbols of PUCCH resources determined by the UE

Including one or more of the following:

a) The number of symbols for PUCCH transmission indicated by the network side;

b) The number of symbols of the PUCCH resource with the largest or smallest number of symbols in the PUCCH set. The PUCCH set may be: a PUCCH resource set determined by the UE according to the interval in which the UCI bit number is located.

c) The number of symbols of the PUCCH resource determined in the complete slot or sub-slot.

It is understandable that the number of symbols of PUCCH resources

It can be the number of symbols indicated by the network.

Optionally,

It is the number of symbols of the PUCCH resource determined in each slot or sub-slot for repeated PUCCH transmission, for example, the maximum/minimum number of symbols.

For example, the _{number of symbols of the PUCCH resource corresponding to the number of bits of O UCI} , if multiple PUCCH resources satisfy the condition, the number of symbols of the PUCCH resource with the largest or smallest number of symbols is selected.

Optionally, the UE assumes that PUCCH resources on all slots or sub-slots are available PUCCH resources. For example, if multiple PUCCH resources are configured on a slot or sub-slot, the UE considers that all PUCCH resources are available and determines the PUCCH. Symbol number of resource

That is, it will not be because the number of symbols of the PUCCH resource configured on the slot or sub-slot is greater than the number of available symbols

And sure

Is less than or equal to

Optionally,

Equal to the number of symbols in slot or sub-slot.

Optionally,

It is equal to the number of symbols of the PUCCH resource determined by the UE in the kth slot or sub-slot, for example, k=1.

For some incomplete slots or sub-slots, there are only partial symbols, for example,

Symbols can be used for PUCCH transmission, causing the UE to be unable to perform

PUCCH transmission of symbols, namely

It should be noted that each PUCCH resource identifier can be bound to the PUCCH format. When the UE determines the PUCCH resource, it also determines the PUCCH format.

Embodiment 2: Regarding PUCCH transmission in a rate matching or puncturing manner, and determining an orthogonal cover code sequence.

If the number of available symbols in a slot or sub-slot

Less than the number of symbols for PUCCH resources

Then the UE performs PUCCH transmission in the available symbols.

For example, rate matching (rate matching) or puncturing (puncturing) can be used for PUCCH transmission.

Exemplarily, in

Before

Symbols for PUCCH transmission, not after

Symbols for PUCCH transmission.

Or in

After

Symbols for PUCCH transmission, not in the front

Symbols for PUCCH transmission.

Further, if the PUCCH format uses a time domain OCC sequence, the OCC sequence can be determined in the following manner:

According to the transmission

The number of UCI symbols (n1) and the number of demodulation reference signal (Demodulation Reference Signal, DMRS) symbols (n2) among the symbols to determine the OCC sequence used,

That is, the OCC sequence of the corresponding length is selected according to n1 and n2.

It is understandable that the index value of the OCC sequence (OCC sequence Index) may be configured by the network, or may be a preset value, for example, OCC sequence Index=0.

As shown in Figure 4, the network side configures the UE to perform PUCCH repeated transmission, and PUCCH transmission is performed in 4 sub-slots.

In the first sub-slot in the figure, only the last 4 symbols (3-6) are available. In the last 3 sub-slots, all 7 symbols (0-6) are available. The UE is based on the 7-symbol sub-slot. -PUCCH format configured on the slot for transmission.

If the network is configured with multiple PUCCH resources, each PUCCH resource corresponds to a PUCCH format, and each PUCCH resource corresponds to a preset range of UCI bits. The UE determines the PUCCH format according to the number of UCI bits to be transmitted.

The PUCCH resource transmitted in the first sub-slot (sub-slot that cannot be fully utilized) corresponds to the first 3 symbols (0-2) of the 7 symbols, or the last 4 symbols (3-6).

Optionally, for the 7-symbol PUCCH, the number of DMRS and UCI symbols are 4 and 3, respectively, and the length of the used OCC is 4 and 3, respectively. After the transmitted PUCCH symbol is 4, that is, after truncation, the number of DMRS and UCI symbols are 2 and 2, respectively. Then the length of the used OCC is also 2 and 2, then the OCC Index that the UE can use is equal to the length of the network. The OCC Index configured for the PUCCH of 7 or a predefined OCC Index, for example, Index=0.

Or, truncating the OCC sequence with lengths of 4 and 3, and use 2 of them to form an equivalent OCC sequence.

Example three

The UE determines the number of RBs of the PUCCH resource according to the number of symbols of the PUCCH resource used for PUCCH transmission, and uses the following method to determine:

Among them: M is the number of RBs;

Is the number of subcarriers used to transmit UCI in each RB;

For PUCCH transmission in the slot or sub-slot

The number of symbols in the symbol to transmit UCI;

Q _m represents the modulation method;

r is the code rate, for example, the maximum code rate indicated by the network side through high-level signaling;

M is the minimum number of RBs that satisfy the above inequality.

It should be noted that if the maximum number of RBs for a PUCCH format still cannot satisfy the above inequality, then M is the maximum number of RBs;

O _UCI is the number of bits in at least one of HARQ-ACK, CSI and SR, or the sum of the number of bits in at least two of HARQ-ACK, CSI and SR;

O _CRC represents the number of cyclic redundancy check bits.

For example, for PUCCH format 3, M=16.

In some embodiments, PUCCH transmission can be performed in the first sub-slot, that is, the UE directly uses

PUCCH transmission is performed on a symbol, and the above rules are used to determine the number of RBs for PUCCH resources.

In other embodiments, PUCCH transmission may be performed in the first sub-slot, that is, the network may configure multiple PUCCH resources in the sub-slot, and the PUCCH format of each PUCCH resource and the number of symbols of the PUCCH resource may be different.

The UE selects PUCCH resources according to the number of available symbols in the sub-slot.

For example, the network configures two PUCCH resources, the first PUCCH resource is 4 symbols PUCCH format 3, the second PUCCH resource includes 7 symbols, and the PUCCH format is PUCCH format 3. For the first sub-slot, since there are only 4 available symbols, the first PUCCH is used for transmission; for the second sub-slot, since all 7 symbols are available, the second PUCCH resource is selected.

It is understandable that if there are multiple PUCCH resources

Select the PUCCH resource with the most or least number of symbols. After the PUCCH resource is determined, the number of RBs for the PUCCH resource is determined according to the above rules.

For example, if the number of symbols of the first PUCCH resource is 2, and the number of symbols of the second PUCCH resource is 7, then the PUCCH transmission in the first sub-slot uses the first PUCCH resource, that is, the number of symbols is 2. PUCCH transmission can be performed on the first 2 or last 2 symbols in the first sub-slot.

Example four

UE according to the number of available symbols in each slot or sub-slot

Determine the PUCCH format.

Solution (1): If

The UE uses PF0 for PUCCH transmission, otherwise the UE uses PF1 for PUCCH transmission.

Optionally, in _{the case of O UCI} ≤ 2, use this scheme (1) to determine the PUCCH format;

Solution (2): If

The UE uses PF2 for PUCCH transmission, otherwise the UE uses PF3 or PF4 for PUCCH transmission.

Optionally, in _{the case of O UCI} > 2, use this scheme (2) to determine the PUCCH format.

Wherein, O _UCI is the number of bits of at least one of HARQ-ACK, CSI, and SR, or the sum of the number of bits of at least two of HARQ-ACK, CSI, and SR.

It should be noted that N1 and N2 in the above-mentioned scheme 1 and scheme 2 may be the same or different, and the values of N1 and N2 are not specifically limited in the embodiment of the present invention.

Referring to FIG. 5, an embodiment of the present invention provides a terminal, and the terminal 500 includes:

The first determining module 501 is configured to determine the first parameter of the PUCCH;

The transmission module 502 is configured to perform PUCCH transmission at the first time resource according to the first parameter;

Among them, the first time resource is used for PUCCH repeated transmission.

In some embodiments, the first determining module 501 is further configured to: determine the first parameter of the PUCCH according to the number of available symbols of the first time resource; or, determine the number of symbols transmitted by the PUCCH of the first time resource.
