BACKGROUND

In the new radio (NR) , sub-band full duplex scheme allows a downlink transmission and an uplink transmission performed in the same slot. An uplink transmission may include signals of a physical uplink shared channel (PUSCH) or signals of a physical uplink control channel (PUCCH) . As shown in Fig. 12, if a user equipment (UE) transmits a PUSCH over multiple slots and the UE would transmit a PUCCH with uplink control information (UCI) , such as HARQ-ACK and channel state information (CSI) that overlaps with the PUSCH transmission, the UE multiplexes the UCI in the PUSCH transmission. Thus, the number of coded modulation symbols for transmitting the UCI should be determined. In this way, the UE can determine the occupied resource by the UCI on the PUSCH based on the determined number of coded modulation symbols and transmit the UCI, and the base station (BS) can determine the occupied resource by the UCI on the PUSCH based on the same number of coded modulation symbols and receive the UCI.

DETAILED DESCRIPTION

The detailed description of the appended drawings is intended as a description of preferred embodiments of the present application and is not intended to represent the only form in which the present application may be practiced. It should be understood that the same or equivalent functions may be accomplished by different embodiments that are intended to be encompassed within the spirit and scope of the present application.

Reference will now be made in detail to some embodiments of the present application, examples of which are illustrated in the accompanying drawings.

FIG. 1 illustrates a wireless communication system 100 according to some embodiments of the present application. FIG. 1 includes a BS101 and a (UE 103. An uplink 105 and a downlink 107 are used to transmit data and signal between the BS 101 and the US 103. In the uplink 105, a PUCCH and a PUSCH may be implemented to transmit data and signal from the UE 103 to the BS 101. In the downlink 107, a PDCCH and a PDSCH may be implemented to transmit data and signal from the BS to the UE.

I. NR resource allocation

Before NR UE transmits PUSCH, including dynamic scheduled PUSCH and CG PUSCH, it receives frequency domain resource allocation assignment and time domain resource assignment from NR gNB to determine the frequency and time domain resource of the PUSCH.

I. 1. Resource allocation in frequency domain

For dynamically scheduled PUSCH and CG Type 2 PUSCH, the UE shall determine the resource assignment using the resource allocation field in the detected PDCCH DCI. But for CG Type 1 PUSCH, the resource assignment applied for the transmission is provided by higher layer parameter frequencyDomainAllocation in configuredGrantConfig. The frequency domain resource assignment indicates to a scheduled UE a set of resource blocks (RB) within the active bandwidth part. The RB indexing for resource allocation is determined within the UE's active bandwidth part.

I. 2. Resource allocation in time domain

I. 2. i. Dynamically scheduled PUSCH

For dynamically scheduled PUSCH, the 'time domain resource assignment' field value m of the DCI provides a row index m + 1 to an allocated table, and the used resource allocation table could be predefined by 3GPP specification or could be configured by ahigher layer parameter. The indexed row defines the slot offset K ₂, the start and length indicator SLIV, or directly the start symbol S and the allocation length L, and the number of repetitions (if numberOfRepetitions is present in the resource allocation table) to be applied in the PUSCH transmission, where slot offset K ₂ is used to indicate the number of slots between the DCI received slot and PUSCH transmitted slot.

There are four main schemes for resource allocation in time domain of dynamically scheduled PUSCH, including PUSCH repetition Type A introduced in Rel-15, and PUSCH repetition Type B introduced in Rel-16. Enhancements on PUSCH repetition type A are beneficial for PUSCH coverage enhancements for TDD. It is recommended to support the specification in Rel-17. TB processing over multi-slot PUSCH (TBOMS) is beneficial for PUSCH coverage enhancements. It is recommended to support TBOMS in Rel-17. For a certain PUSCH transmission, the scheme used could be configured by a higher layer parameter. Time domain resource allocation for these four schemes could be found as follows.

For PUSCH repetition Type A, the starting symbol S relative to the start of the slot, and the number of consecutive symbols L counting from the symbol S allocated for the PUSCH are determined from the start and length indicator SLIV of the indexed row.

if (L-1) ≤7 then

SLIV=14· (L-1) +S

else

SLIV=14· (14-L+1) + (14-1-S)

where 0＜L≤14-S.

When transmitting PUSCH scheduled by DCI format 0_1 or 0_2 in PDCCH with CRC scrambled with C-RNTI, MCS-C-RNTI, or CS-RNTI with NDI=1, the number of repetitions K is determined as:

- if numberOfRepetitions is present in the resource allocation table, the number of repetitions K is equal to numberOfRepetitions;

- else if the UE is configured with pusch-AggregationFactor, the number of repetitions K is equal to pusch-AggregationFactor;

- otherwise K=1.

For PUSCH repetition Type A, in case K>1, the same symbol allocation is applied across the K consecutive slots. The UE shall repeat the TB across the K consecutive slots applying the same symbol allocation in each slot.

For example, assuming K ₂ =1, S=2 (indicating that the PUSCH transmission starts at the symbol #2, i.e., the third symbol) , L=8 (indicating that the length of the PUSCH transmission is 8) , K=4, then the time domain resource for PUSCH with PUSCH repetition Type A could be seen in FIG. 2. In FIG. 2, each slot includes 14 symbols, and one rectangle in one slot indicates 2 symbols. In FIG. 2, data transmitted in PUSCH #0 to PUSCH #3 are identical. Thus, the data transmitted in PUSCH #0 are transmitted 4 times in total.

For PUSCH repetition Type A, a PUSCH transmission in a slot of a multi-slot PUSCH transmission is omitted if any symbol of the PUSCH overlaps with the set of symbols of the slot that are indicated to a UE as downlink by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated.

For PUSCH repetition Type B, the number of nominal repetitions is given by numberOfRepetitions. For the n-th nominal repetition, n = 0, …, numberOfRepetitions -1,

- The slot where the nominal repetition starts is given by

and the starting symbol relative to the start of the slot is given by

- The slot where the nominal repetition ends is given by

and the ending symbol relative to the start of the slot is given by

Here K _s is the slot where the PUSCH transmission starts, and

is the number of symbols per slot. The starting symbol S relative to the start of the slot, and the number of consecutive symbols L counting from the symbol S allocated for the PUSCH are provided by startSymbol and length of the indexed row of the resource allocation table, respectively.

For PUSCH repetition Type B, a symbol that is indicated as downlink by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated, is considered as an invalid symbol for PUSCH repetition Type B transmission. After determining the invalid symbol (s) for PUSCH repetition type B transmission for each of the K nominal repetitions, the remaining symbols are considered as potentially valid symbols for PUSCH repetition Type B transmission. If the number of potentially valid symbols for PUSCH repetition type B transmission is greater than zero for a nominal repetition, the nominal repetition consists of one or more actual repetitions, where each actual repetition consists of a consecutive set of all potentially valid symbols that can be used for PUSCH repetition Type B transmission within a slot. An actual repetition with a single symbol is omitted except for the case of L=1.

An actual repetition is omitted if any symbol of the PUSCH is overlapped with the set of symbols of the slot that are indicated to a UE as downlink by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated.

For example, assuming K ₂ =0, S=2, L=8, K=4, then the time domain resource for PUSCH with PUSCH repetition Type B could be seen in FIG. 3. In FIG. 3, each slot includes 14 symbols, and one rectangle in one slot indicates 2 symbols. FIG. 3 (A) shows four nominal repetitions (nominal repetition #0 to nominal repetition #3) . Upon consideration of downlink transmissions indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, FIG. 3 (B) shows five actual repetitions (actual repetition #0 to actual repetition #4) , in which each of the five actual repetitions may occupy different symbols in a slot.

For enhanced PUSCH repetition Type A, the resource allocation in time domain is almost the same as PUSCH repetition type A, except that the number of repetitions is counted on the basis of available slots. A slot is determined as unavailable if at least one of the symbols indicated by TDRA (time domain resource allocation) for a PUSCH in the slot overlaps with the symbol not intended for UL transmissions, and semi-static flexible symbol configured by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated, is considered as available.

For example, assuming K ₂ =1, S=2, L=8, K=4, then the time domain resource for PUSCH with enhanced PUSCH repetition Type A could be seen in FIG. 4. In FIG. 4, each slot includes 14 symbols, and one rectangle in one slot indicates 2 symbols. In FIG. 4, data transmitted in PUSCH #0 to PUSCH #3 are identical. Thus, the data transmitted in PUSCH #0 are transmitted 4 times in total. In slot #2, the first symbol to fourth symbol are occupied by a downlink transmission (e.g., configured by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated) , and the transmissions of PUSCH #1 to PUSCH #3 are in slot#3-slot#5.

For TBOMS, time domain resource determination can be performed via PUSCH repetition Type A like TDRA. The number of slots K allocated for TBOMS is determined by using a row index of a TDRA list, configured via RRC and is counted based on the available slots for UL transmission. The transmission in each slot could be named as one transmission part of the TB in this invention. The determination of available slots is as defined in enhanced PUSCH repetition Type A.

For example, assuming K ₂ =1, S=2, L=8, K=4, then the time domain resource for PUSCH with TBOMS could be seen in FIG. 5. In FIG. 5, each slot includes 14 symbols, and one rectangle in one slot indicates 2 symbols. In FIG. 5, data transmitted in PUSCH #0 to PUSCH #3 may be different. A transport block may be divided into four parts, and the four parts are transmitted in PUSCH #0 to PUSCH #3, respectively. In slot #2, the first symbol to fourth symbol are occupied by a downlink transmission (e.g., configured by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated) , and the transmissions of PUSCH #1 to PUSCH #3 are in slot#3-slot#5.

I. 2. ii. CG (configured grant) PUSCH

For CG Type 1 PUSCH transmissions, the higher layer parameter timeDomainAllocation value m provides a row index m+1 pointing to the determined time domain resource allocation table, where the start symbol and length are determined following the procedure defined here for dynamically scheduled PUSCH. For CG Type 2 PUSCH transmissions, the resource allocation follows UL grant received on the DCI.

There are also four main schemes for resource allocation in time domain of CG PUSCH including Type 1 or Type 2. They have some differences in the schemes for dynamically scheduled PUSCH, such as PUSCH repetition Type A, PUSCH repetition Type B, enhanced PUSCH repetition Type A and TBOMS. The number of (nominal) repetitions K to be applied to the transmitted transport block is provided by the indexed row in the time domain resource allocation table if numberOfRepetitions is present in the table; otherwise K is provided by the higher layer configured parameters repK. Other procedures defined in clause of dynamically scheduling could be reused.

For PUSCH repetition Type B, for PUSCH transmissions with a Type 1 or Type 2 configured grant, the nominal repetitions and the actual repetitions are determined according to the procedures for PUSCH repetition Type B defined in clause of dynamically scheduling PUSCH.

II. Multiplexing of uplink control information (UCI)

If a UE transmits a PUSCH over multiple slots and the UE would transmit a PUCCH with HARQ-ACK and/or CSI information over a single slot that overlaps with the PUSCH transmission in one or more slots of the multiple slots, and the PUSCH transmission in the one or more slots fulfills the conditions in clause 9.2.5 for multiplexing the HARQ-ACK and/or CSI information, the UE multiplexes the HARQ-ACK and/or CSI information in the PUSCH transmission in the one or more slots.

If a UE transmits a PUSCH with repetition Type B and the UE would transmit a PUCCH with HARQ-ACK and/or CSI information over a single slot that overlaps with the PUSCH transmission in one or more slots, the UE expects all actual repetitions of the PUSCH transmission that would overlap with the PUCCH transmission to fulfill the conditions in clause 9.2.5 (in 3GPP TS 38.213 V17.0.0 (2021-12) ) for multiplexing the HARQ-ACK and/or CSI information, and the UE multiplexes the HARQ-ACK and/or CSI information in the earliest actual PUSCH repetition of the PUSCH transmission that would overlap with the PUCCH transmission and includes more than one symbol. The UE does not expect that all actual repetitions that would overlap with the PUCCH transmission do not include more than one symbol.

For UCI on PUSCH, the procedure includes:

(1) UCI bit sequence generation:

this procedure is to determine the information bits of the UCI, including HARQ-ACK, CSI part 1 and part 2, and CG-UCI. The output of this procedure is a ₀,a ₁, a ₂, a ₃, ..., a _A-1, where A is the payload size; the details could be found in the specification 3GPP TS 38.212 V17.0.0 (2021-12) .

(2) Code block segmentation and CRC attachment:

the details could be found in the specification 3GPP TS 38.212 V17.0.0 (2021-12) .

(3) Channel coding of UCI:

the UCI could be encoded by polar or channel coding of small block lengths; the details could be found in the specification 3GPP TS 38.212 V17.0.0 (2021-12) ;

(4) Rate matching.

V. Sub-band full duplex

In order to realize superior data rate and latency, 5G spectrum on higher frequency bands is inevitable. It is a big question to overcome the coverage reduction on such carriers introduced in 3GPP Rel. 18, since 3GPP Rel. 18 may introduce a new duplexing scheme. that the new duplexing scheme enables simultaneous use of downlink and uplink within a TDD carrier using a non-overlapping frequency resource, which could be named sub-band full duplex. The intention of this scheme is to extend the duration over which uplink transmission could occur for improved uplink coverage and capacity. And the simultaneous use of DL and UL is only at gNB, not at UE side. An example of a duplexing scheme could be seen in FIG. 6. In FIG. 6, DL (downlink) #0 and DL #1 are duplex with UL (uplink) #0 in different sub-bands of slot #0. In FIG. 6, DL #2 and DL #3 are duplex with UL #1 in different sub-bands of slot #1.

According to the background NR resource allocation above, it is observed that gNB could only indicate one frequency domain resource in the BWP (Band Width Part) . For PUSCH repetition Type A, PUSCH repetition Type B, and enhanced PUSCH repetition A, frequency resource of each repetition is same. For TBOMS, frequency resource of each part of the transmission is same.

As a result, in sub-band full duplex scenario, the indicated frequency domain resource may cross multiple sub-bands configured with different transmission directions in some slots, such as PUSCH 1 shown in FIG. 7. This situation could be avoided by indicating a small frequency domain resource by gNB, which means that the indicated frequency domain resource would cross multiple sub-bands configured with different transmission directions in any slot. For dynamically scheduled PUSCH without repetition, this method would not have any limitation. However, for CG PUSCH transmission without repetition or PUSCH with repetition or TBOMS, always indicating a small frequency domain resource is not reasonable considering the scheduling flexibility and resource utilization.

Therefore, some methods of the present application could be used to solve the issue of how to transmit PUSCH if the indicated frequency domain resource of PUSCH would cross multiple sub-bands configured with different transmission directions in sub-band full duplex scenario. The embodiments of the present application are described as follows.

V. 1 Solution 1: at least two frequency domain resources are indicated, and they are for different slot separately. The different slots include slot for normal slot and the slot for sub-band full duplex slot.

V. 1 Solution 1-1

For PUSCH transmission with PUSCH repetition type A, these two resource assignments could be different and are used to indicate two frequency domain resource used in slots configured with sub-band full duplex scheme and normal slots respectively.

For each PUSCH repetition, the used frequency domain resource is chosen according to the whether the occupied slot of the repetition is configured with sub-band full duplex scheme. For example, in FIG. 8, slot #0 and slot #1 are configured with sub-band full duplex scheme, one frequency domain resource was used for PUSCH repetition 1and PUSCH repetition 2; and the other frequency domain resource is used for PUSCH repetition 3 and PUSCH repetition 4 in normal slot #2 and slot #3.

V. 1 Solution 1-2

For PUSCH transmission with PUSCH repetition type B, these two resource assignments could be different and are used to indicate two frequency domain resource used in slots configured with sub-band full duplex scheme and normal slots respectively.

V. 1 Solution 1-2-1

For each nominal PUSCH repetition, the used frequency domain resource is chosen according to the whether the occupied slot (decided by the starting symbol) of the nominal repetition is configured with sub-band full duplex scheme. For example, in FIG. 9 (A) , the starting symbol of nominal repetition 1, nominal repetition 2 and nominal repetition 3 are in slot #0 and slot #1 who are configured with sub-band full duplex scheme, so one lower frequency domain resource configured for slots with sub-band full duplex was used for nominal repetition 1, nominal repetition 2 and nominal repetition 3, the other frequency domain resource is used for nominal repetition 4. After that, the resource for actual repetition could be determined according to current technology in section 1, for example in FIG. 9 (A) , the determined actual repetition could be found in FIG. 9 (B) , seven (7) actual repetitions are decided for PUSCH transmission.

V. 1 Solution 1-2-2

For each actual PUSCH repetition, the used frequency domain resource is chosen according to the whether the occupied slot of the actual repetition is configured with sub-band full duplex scheme. For example, in FIG. 10, in slot #0 and slot #1 configured with sub-band full duplex scheme, one frequency domain resource was used for actual PUSCH repetition 1 to actual PUSCH repetition 4, in normal slot #2 and slot #3, the other frequency domain resource is used for actual PUSCH repetition 5, actual PUSCH repetition 6, and actual PUSCH repetition 7.

V. 1 Solution 1-3

For PUSCH transmission with TBOMS, these two resource assignments could be different and are used to indicate two frequency domain resource used in slots configured with sub-band full duplex scheme and normal slots respectively.

For each transmission part, the used frequency domain resource is chosen according to whether the occupied slot of transmission part is configured with sub-band full duplex scheme. For example, in FIG. 11, in slot #0 and slot #1 configured with sub-band full duplex scheme, one frequency domain resource was used for transmission part 1 and transmission part 2, in normal slot #2 and slot #3, the other frequency domain resource is used for transmission part 3 and transmission part 4.

V. 2 Solution 2: one frequency domain resource is indicated, then UE adjusts this resource to adapt the sub-band configuration according to predefined rules.

For example, for a slot without sub-band full duplex, the indicated frequency resource is applied; and for a slot with sub-band full duplex, the applied frequency resource would be reduced to fit the size of the sub-band. In this way, at least two frequency domain resources could be determined for different slot separately. Use of these two resources could be the same as Solution 1.

For all solutions in the disclosure of the present application , the term "slot" could be replaced by "time unit. " A time unit may one or multiple frames, one or multiple sub-frames, one or multiple slots, one or multiple sub-slots, or one or multiple symbols.

According to above solutions, we can find that in full duplex scenario, for PUSCH repetition Type A, TB processing over multiple slots, or PUSCH repetition Type B, there could be at least two frequency domain resources determined for PUSCH transmission and the size of these frequency domain resources could be different.

If one PUCCH with HARQ-ACK and/or CSI information over in one slot is overlapped with PUSCH slot #0, PUSCH slot #1, and/or PUSCH slot #2 over multiple slots as shown in FIG. 12. If the PUSCH transmission in the one or more slots fulfills the conditions for multiplexing the HARQ-ACK and/or CSI information, the UE multiplexes the HARQ-ACK and/or CSI information in the PUSCH transmission in the one or more slots. The frequency domain resource of the PUSCH could be different in different slots, which means at least two values could be calculated for parameter

How to calculate the number of coded modulation symbols of UCI should be decided.

In the present application, for all the embodiments, except the enhancement in the embodiment, other procedure could be same as the number of coded modulation symbols of UCI calculation method in II. Multiplexing of uplink control information (UCI)

Similarly, if a UE transmits a PUSCH with repetition Type B and the UE would transmit a PUCCH with HARQ-ACK and/or CSI information over a single slot that overlaps with the PUSCH transmission in one or more slots, the UE expects all actual repetitions of the PUSCH transmission that would overlap with the PUCCH transmission to fulfill the conditions for multiplexing the HARQ-ACK and/or CSI information, and the UE multiplexes the HARQ-ACK and/or CSI information in the earliest actual PUSCH repetition of the PUSCH transmission that would overlap with the PUCCH transmission and includes more than one symbol. The frequency domain resource of the PUSCH could be different in different repetitions, which means at least one value could be calculated for parameter

How to calculate coded modulation symbols of UCI should be decided.

The disclosure of the present application proposes embodiments to determine the number of coded modulation symbols of UCI. For example, the embodiments may include calculating the number of coded modulation symbols of UCI on PUSCH when there are at least two frequency domain resources are determined for the PUSCH in sub-band full duplex scenario. The disclosure of the present application may assume gNB (generalized NodeB) configures the different transmission direction for sub-bands in some slot by higher layer signaling or dynamic signaling. Thus, the UE may know whether a slot is with sub-band full duplex or not and the transmission direction of each sub-band.

When there are at least two frequency domain resources are determined for the PUSCH in sub-band full duplex scenario, determining the number of coded modulation symbols of UCI may include Step 1 and Step 2. Furthermore, Step 2 may be either Step 2-1 or Step 2-2.

VI. Step 1:

Step 1 may include determining a PUCCH with UCI over a single slot. Step 1 may include determining the PUCCH overlapping with the PUSCH transmission in one or more slots. The frequency domain resources for the PUSCH transmission in one or more slots include at least two numbers of subcarriers. The UCI may be HARQ-ACK and/or CSI information.

VII. Step 2-1:

Step 2-1 may include determining the coded modulation symbols of UCI based on the one number of subcarriers among the at least two numbers of subcarriers.
