Disclosure of Invention

Aspects of the present disclosure provide a method for a User Equipment (UE) to report Uplink Control Information (UCI) reports based on a plurality of Physical Uplink Control Channel (PUCCH) resources configured to the UE. In one embodiment, a UE receives configuration information of a PUCCH resource and one or more PUCCH resource sets from a Base Station (BS) in a wireless communication system. The UE also receives an index from a PUCCH resource indicator field in Downlink Control Information (DCI) providing the downlink transmission. The UE may determine one or more PUCCH resource sets from the configured one or more PUCCH resource sets based on a payload size (payload size) of UCI including hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback for the downlink transmission. The UE may also determine a plurality of PUCCH resources from the determined set of one or more PUCCH resources based on the received index and transmit UCI on one of the determined plurality of PUCCH resources.

In one example, the plurality of determined PUCCH resources are distributed over different sub-bands.

In one embodiment, a UE receives configuration information for one or more PUCCH resource sets each including a first resource list, and determines a first PUCCH resource set from the configured one or more PUCCH resource sets based on a payload size of UCI including HARQ-ACK feedback for a downlink transmission. The UE determines a plurality of PUCCH resources from a first resource list in a first PUCCH resource set based on the received index according to an index-to-PUCCH resource mapping rule.

In one embodiment, a UE receives configuration information for one or more PUCCH resource sets each including a plurality of second resource lists, and determines a second PUCCH resource set from the configured one or more PUCCH resource sets based on a payload size of UCI including HARQ-ACK feedback for downlink transmission. The UE also determines a plurality of PUCCH resources from a plurality of second resource lists in a second PUCCH resource set based on the received indices. In one example, each of the plurality of PUCCH resources is from a different one of the plurality of second resource lists and is associated with the received index.

In one embodiment, a UE receives configuration information for one or more PUCCH resource sets each including a third resource list, wherein at least two PUCCH resource sets of the one or more PUCCH resource sets are configured to have the same maximum UCI payload size, and determines a plurality of third PUCCH resource sets from the configured one or more PUCCH resource sets based on a payload size of UCI including HARQ-ACK feedback for a downlink transmission, wherein the plurality of third PUCCH resource sets have the same maximum UCI payload size. The UE may also determine a plurality of PUCCH resources from a plurality of third resource lists in a plurality of third PUCCH resource sets based on the received index. In one example, each of the plurality of PUCCH resources is from a different third resource list of the plurality of third resource lists and is associated with the received index.

In one embodiment, the UE may receive configuration information for one or more PUCCH resource sets each including a fourth resource list, each fourth resource list including a plurality of PUCCH resource candidate sets, each PUCCH resource candidate set including a plurality of PUCCH resources.

Detailed Description

I. Multiple PUCCH resources for UCI reporting

Fig. 1 illustrates a wireless communication system 100 in accordance with some embodiments of the present disclosure. System 100 may include a User Equipment (UE)110 and a Base Station (BS) 120. In some examples, system 100 employs a fifth generation (5G) New Radio (NR) air interface developed by the third generation partnership project (3 GPP). In some examples, system 100 employs other wireless communication technologies developed by various standard development organizations. In some examples, system 100 employs non-standardized wireless communication technologies.

In some examples, BS120 may be a base station implementing a gNB node specified in the 5G NR air interface standard developed by 3 GPP. In one example, BS120 may be configured to control one or more antenna arrays to form a directional Tx or Rx beam for transmitting or receiving wireless signals. The UE110 may be a mobile phone, a laptop computer, a vehicle-mounted mobile communication device, a utility meter (utility meter) fixed at a specific location, and the like. Similarly, in one example, BS 110 may employ one or more antenna arrays to generate directional Tx or Rx beams for transmitting or receiving wireless signals. Depending on the air interface between BS120 and UE110, BS120 and UE110 may communicate with each other according to respective communication protocols.

In various embodiments, UE110 may send (or report) Uplink Control Information (UCI) on a Physical Uplink Control Channel (PUCCH) to support data transmission on a downlink transport channel or an uplink transport channel UCI may include a hybrid automatic repeat request acknowledgement (HARQ-ACK) for a received downlink shared channel (D L-SCH) transport block (or transport sub-block when using Code Block Grouping (CBG)), Channel State Information (CSI) related to downlink channel conditions useful for downlink scheduling, and a Scheduling Request (SR) indicating that UE110 needs uplink resources for uplink shared channel (UP-SCH) transmission.

The UCI may be transmitted on PUCCH resources exclusively allocated for PUCCH transmission. For example, PUCCH resources may be frequency and time domain physical transmission resources, such as resources of multiple symbols and multiple Physical Resource Blocks (PRBs) on an Orthogonal Frequency Division Multiplexing (OFDM) resource grid.

In an example (not shown in fig. 1), BS120 may configure UE110 with one PUCCH resource corresponding to UCI to be transmitted. The configuration may be performed, for example, by Radio Resource Control (RRC) signaling, Medium Access (MAC) layer Control Element (CE), downlink control information, or a combination thereof. The configured PUCCH resources may be readily available to UE110, assuming system 100 operates in the licensed spectrum. However, when introducing licensed spectrum into the system 100, the configuration of a single PUCCH resource for UCI reporting on unlicensed spectrum may be unreliable.

Fig. 2A illustrates a situation in which the system 100 operates on an unlicensed band 201, the unlicensed band 201 is divided into a plurality of sub-bands from 210 to 213, each having, for example, a bandwidth of 20MHz the BS120 may configure the PUCCH resource 220 to the UE110 for transmission of UCI prior to transmission of UCI, the UE110 may perform an access procedure, such as a listen-before-talk (L BT) access procedure, on each sub-band 210 and 213 to determine whether the sub-band 210 and 213 are available, as shown, the L BT access procedure may fail on the sub-bands 211 and 213 due to detection of transmission activity by another transmitter in the sub-bands 211 and 213.

The PUCCH resource 220 may be scheduled in advance by the BS120 without knowing whether the corresponding subband 211 is available when the PUCCH 220 is to be transmitted. When it is determined that the subband 211 is not available, transmission of the PUCCH resource 220 may have to be dropped. Failure to feedback important information (e.g., HARQ-ACK) when operating on unlicensed spectrum 201 may reduce the performance of system 100.

FIG. 2B illustrates a situation where multiple

candidate PUCCH resources

230 and 233, which are respectively distributed in

different subbands

210 and 213, are configured, as shown, when subbands 210 and 212 are available due to L BT access procedures,

candidate PUCCH resources

230 and 232 may be used for UCI reporting, UE110 may select a PUCCH resource (e.g., PUCCH resource 230) from

candidate PUCCH resources

230 and 232 to perform UCI transmission.

Fig. 1 shows a UCI reporting process 130 corresponding to the scenario of fig. 2B, in a first step 131 of the process 130, configuration information of a plurality of PUCCH resources 230-.

The

subbands

210 and 213 in the examples of fig. 2A-2B may be included in a bandwidth part (BWP) or component carriers configured to the UE 110. in other examples, the

subbands

210 and 213 may each be configured as component carriers and combined using a carrier aggregation scheme.

Multiple PUCCH resources for HARQ-ACK feedback

1. Example of HARQ-ACK feedback with PUCCH resources

Fig. 3 shows an example of a PUCCH resource configuration 320, a resource format configuration 330, and a PUCCH resource 301 corresponding to the PUCCH resource configuration 320. As shown, the PUCCH resource configuration 320 may indicate a PUCCH resource ID 321, a starting PRB 322 in the frequency domain, a resource format 323, and possibly other parameters. Resource format configuration 330 (corresponding to resource format 323 indicated by PUCCH resource configuration) may indicate a starting symbol 331, a number of PRBs 332 (optional), a number of symbols (optional), and possibly other parameters.

PUCCH resources 301 are shown in OFDM resource grid 310 as specified by PUCCH resource configuration 320 and resource format configuration 330. For example, the PUCCH resource 301 has a PUCCH resource ID of #2, starting from PRB #4 up to PRB #11 (for 8 PRBs) and starting from symbol #2 up to symbol #7 (for 6 symbols) in the frequency domain. As shown, PUCCH resources in the frequency domain and the time domain may be identified by PUCCH resource configuration.

Fig. 4 shows an example of PUCCH resource set configuration 400 for HARQ-ACK feedback. As shown, the PUCCH resource set configuration 400 may indicate the number (e.g., 4) of PUCCH resource sets (e.g., with a label of #1, #2, etc.). Each PUCCH resource set for HARQ-ACK reporting may generally include a PUCCH resource set ID (401), information of a unique maximum UCI payload size (402) (e.g., 2 bits, 10 bits, or 40 bits), and a resource list (403) including one or more PUCCH resource IDs. In the example of fig. 4, the information (402) of the maximum UCI payload size is indicated in the form of a maximum payload size reduction of 1 (represented by maxpayloyadminus 1). From the PUCCH resource ID, a PUCCH resource configuration as described in the example of fig. 3 may be identified.

Fig. 5 shows an example of a process 500 for the UE110 to determine which PUCCH resource from the selected set of PUCCH resources 510 should be used for HARQ-ACK feedback. For example, the UE110 may receive configuration information for the number of PUCCH resource sets (e.g., 4). During the first step, the UE110 may select one PUCCH resource set 510 from the configured PUCCH resource sets based on the payload size of the UCI to be transmitted. For example, the selected PUCCH resource set 510 may indicate a minimum maximum payload size that can accommodate a payload size to be transmitted among the configured PUCCH resource sets.

During the second step, based on the index (referred to as an indication index) from the DCI providing the downlink transmission, the UE110 may select a PUCCH resource (represented by a PUCCH resource ID) from a resource list 511 in the selected PUCCH resource set 510. This option is exemplified in the mapping table 520, where different indices (referred to as mapping indices) are associated with different PUCCH resource IDs in the mapping table 520.

Each of the mapping indexes in the mapping table 520 may be explicitly indicated by an indication index conveyed by the UCI or may be obtained based on the indication index (implicitly indicated) conveyed by the UCI. For example, when the size of the resource list 511 is less than or equal to 8, an indication index in a PUCCH resource indicator field (e.g., having a length of 3 bits) in the corresponding DCI may be used as a mapping index in the mapping table 520. In contrast, when the size of the resource list 511 is greater than 8 (e.g., 30), the mapping index used in the mapping table may be calculated based on the value (indication index) of the PUCCH resource indicator field and other parameters received by the corresponding PDCCH with which the DCI is associated.

Fig. 6 illustrates an example process 600 for providing a single PUCCH resource for HARQ-ACK feedback. Process 600 may be performed at UE 110. System 100 is used to illustrate process 600. Process 600 may begin at S601 and proceed to S610.

At S610, configuration information for a plurality of PUCCH resources and one or more PUCCH resource sets may be received at UE110 from BS120, e.g., through RRC signaling. The configuration information may be sent with a separate RRC message.

At S620, an indication index from a PUCCH resource indicator field in DCI providing a downlink transmission may be received. For example, the downlink transmission may be a transmission of a Physical Downlink Shared Channel (PDSCH) or a transmission of a semi-persistent scheduling (SPS) PDSCH version. DCI associated with a downlink transmission may indicate PUCCH resources for received HARQ-ACK feedback for the downlink transmission by using a PUCCH resource indicator. In addition, the DCI may provide a time offset (e.g., in terms of slots or symbols) relative to the DCI or downlink transmission to indicate the timing of the PUCCH resources for HARQ-ACK feedback.

The UCI carrying HARQ-ACK feedback may be sent later on the indicated PUCCH resources. In some examples, multiple downlink transmissions on the same or different carriers occurring over multiple time periods may be indicated with the same PUCCH resource, and HARQ-ACK feedback for the multiple downlink transmissions may form a codebook and may be transmitted using the indicated PUCCH resource. Accordingly, the payload size of the UCI carrying the codebook may vary depending on the number of multiple downlink transmissions.

In some examples, the BS120 may request the UE 120 to provide CSI reports along with HARQ-ACK feedback for a particular downlink transmission, which may increase the payload size of the UCI. In addition, the UE110 may need to send an SR to request uplink transmission resources. The SR may also be included in the UCI.

At S630, a PUCCH resource set may be determined from the PUCCH resource set configured at S610 based on a payload size of UCI including at least HARQ-ACK feedback for downlink transmission at S620.

At S640, PUCCH resources may be determined from the PUCCH resource set determined at S630 based on the indication index received at S620. For example, the indication index may explicitly or implicitly indicate a mapping index to a PUCCH resource list in the PUCCH resource set determined at S630.

At S650, UCI may be transmitted on the PUCCH resource determined at S640. The process 600 may then proceed to S699 and terminate at S699.

In process 600, a set of PUCCH resources with a certain maximum UCI payload size may provide multiple PUCCH resources suitable for different types of PUCCH structures, e.g., a more flexible PUCCH structure is defined in NR as compared to long term evolution (L TE) to address different applications and use cases.

Accordingly, at step S620, the BS120 may determine an indication index corresponding to the PUCCH resource based on the corresponding PUCCH structure and optionally other parameters (e.g., channel conditions, UE capabilities, etc.) suitable for the particular application. The indication index is then provided to UE 110.

2. Example of providing multiple PUCCH resources for HARQ-ACK feedback

Fig. 7 illustrates a HARQ-ACK feedback process 700 according to an embodiment of the present disclosure. In process 700, multiple PUCCH resources are provided for HARQ-ACK feedback based on the resource mapping rule indexed to PUCCH. Process 700 may be performed by UE110 and system 100 is used to explain process 700.

As shown in fig. 7, process 700 begins at S701, ends at S799, and includes steps from S710 to S750. Steps S710 to S730 may be similar to steps S610 to S630, respectively, in the example of fig. 6. However, steps S740 to S750 are different from steps S640 to S650. The differences between process 600 and process 700 are highlighted by underlining in fig. 7.

Specifically, at S740, a plurality of PUCCH resources may be determined from the resource list in the PUCCH resource set determined at S730 based on the indication index received at S720. In particular, step S740 is performed based on an index-to-PUCCH resource mapping rule that associates a plurality of PUCCH resources with one indication index.

Fig. 8 illustrates an example of an index to PUCCH resource mapping rule according to an embodiment of the present disclosure. As shown, the selected PUCCH resource set 810 includes a resource list 811. The number of candidate PUCCH resources (for use) may be selected from the resource list 811 based on the mapping table 820

Representation). In the example of figure 8, it is shown that,

taking the value of 3. In one of the various examples, the display may be,

may be a default value or may be signaled from BS120 to UE110 through RRC, MAC CE, or DCI signaling.

The mapping index in the mapping table 820 may be explicitly or implicitly indicated by the indication index received at S720. Then, three PUCCH resource IDs (e.g., 10 th ID, 11 th ID, and 12 th ID of the resource list 811) associated with the mapping index (e.g., index 3) may be determined according to the mapping table 820. As such, the indication index may be mapped to an expected PUCCH resource.

At S750, UCI may be transmitted on at least one of the plurality of PUCCH resources determined at S740. for example, the candidate PUCCH resources determined at S740 may be distributed over a plurality of subbands. following the L BT access procedure, a subset of the plurality of subbands is available.

Fig. 9 illustrates another HARQ-ACK feedback process 900 according to an embodiment of the present disclosure. In process 900, multiple PUCCH resources are provided for HARQ-ACK feedback based on a selected PUCCH resource set including multiple resource lists. Process 900 may be performed by UE110 and system 100 is used to explain process 900.

As shown in fig. 9, the process 900 starts at S901, ends at S999, and includes steps from S910 to S950. Compared to the process 600 in the example of fig. 6, steps S920 to S930 may be similar to steps S620 to S630, while steps S910, S940, and S950 are different from steps S610, S640, and S650. The differences between process 600 and process 900 are highlighted by underlining in fig. 9.

Specifically, at S910, configuration information for a plurality of PUCCH resources and one or more PUCCH resource sets may be received. In particular, among those PUCCH resource sets, a plurality of PUCCH resource sets may each include a plurality of resource lists.

At S940, a plurality of PUCCH resources may be determined from the plurality of resource lists of the PUCCH resource set determined at S930 based on the indication index received at S920.

Fig. 10 shows an example of determining a plurality of PUCCH resources from a plurality of resource lists in a selected PUCCH resource set 1010. The selected PUCCH resource set 1010 may include multiple resource lists 1011a-1011 n. Suppose to determine

And one PUCCH resource.

Each of the plurality of PUCCH resources may be from a different one of resource lists 1011a-1011n in the selected PUCCH resource set 1010.

In the example of figure 10, it is shown,

may be equal to the number of resource lists 1011a-1011 n. Therefore, as shown in mapping table 1020, a plurality of PUCCH resource IDs each from a different one of resource lists 1011a-1011n may be determined corresponding to the mapping index determined based on the indication index received at S920, and the PUCCH resource ID associated with the mapping index may be selected. The association between the PUCCH resource ID and the mapping index may be predefined.

Figure 11 illustrates the determination from multiple resource lists 1011a-1011n in a selected PUCCH resource set 1110Another example of multiple PUCCH resources. In the example of fig. 11, the number of PUCCH resources to be determined

May be less than the number of resource lists 1110a-1110n in the selected PUCCH resource set 1110. As shown, two resource lists 1110a and 1110c (a first resource list and a third resource list) are selected (e.g., based on predefined rules), and based on the mapping index, two PUCCH resource IDs may be determined from the two resource lists 1110a and 1110 c.

Similar to the example of fig. 8, the number of PUCCH resources

May be a default number or may be indicated by RRC, MAC CE or DCI signaling. In other examples, the determination may be made in other different ways

At S950, UCI may be transmitted on at least one PUCCH resource of the plurality of PUCCH resources determined at S940.

Fig. 12 shows another HARQ-ACK feedback process 1200 according to an embodiment of the present disclosure. In process 1200, multiple PUCCH resources are provided for HARQ-ACK feedback based on multiple selected PUCCH resource sets having the same maximum UCI payload size. Process 1200 may be performed by UE110 and system 100 is used to explain process 1200.

As shown in fig. 12, process 1200 begins at S1201, ends at S1299, and includes steps from S1210 to S1250. Compared to the process 600 in the example of fig. 6, step S1220 may be similar to step S620, while steps S1210 and S1230 to S1205 are different from steps S610 and S640 to S650. The differences between process 600 and process 1200 are highlighted by underlining in fig. 12.

Specifically, at S1210, configuration information of a plurality of PUCCH resources and a plurality of PUCCH resource sets may be received. In particular, some of the plurality of PUCCH resource sets may be configured to have the same maximum UCI payload size. There may be different maximum UCI payload sizes in the configuration information, each maximum UCI payload size being associated with multiple PUCCH resource sets. Accordingly, a plurality of PUCCH resource sets may be selected corresponding to a payload size of UCI to be transmitted.

At S1230, a plurality of PUCCH resource sets may be determined from the configured plurality of PUCCH resource sets based on a payload size of UCI including at least HARQ-ACK feedback for the downlink transmission described at S1220. For example, the plurality of PUCCH resource sets may have the same maximum UCI payload size, which is the smallest maximum UCI payload size among the configured plurality of PUCCH resource sets that may accommodate UCI.

At S1240, based on the indication index received at S1220, a plurality of PUCCH resources may be determined from a resource list in the plurality of PUCCH resource sets determined at S1230. For example, each of the plurality of PUCCH resources may be from a different one of the plurality of resource lists.

Fig. 13 shows an example of determining a plurality of PUCCH resources from a plurality of selected PUCCH resource sets 1310 and 1320. As shown, the PUCCH resource sets 1310-1320 may each have information 1311-1321 indicating the same maximum UCI payload size, and thus the PUCCH resource sets 1310-1320 are simultaneously selected from the plurality of PUCCH resource sets configured at S1210. The mapping index may be determined from an indication index that explicitly or implicitly indicates the mapping index. Based on the mapping index and according to the mapping table 130, two PUCCH resource IDs may be determined from the two selected PUCCH resource sets 1310 and 1320.

Figure 14 shows another example of determining a plurality of PUCCH resources from a plurality of selected PUCCH resource sets 1410a-1410 n. The PUCCH resource sets 1410a-1410n may include information indicating the same maximum UCI payload size, and thus PUCCH resource sets 1410a-1410n are simultaneously selected from a plurality of PUCCH resource sets configured at S1210. Based on a number of candidate PUCCH resources to be determined

PUCCH resources can be determinedSubsets (numbers) of sets 1410a-1410n

). As an example of this, the following is given,

take the number 2 and therefore select the first set of PUCCH resources and the third set of PUCCH resources from the sets of PUCCH resources 1410a-1410n in fig. 14. Then, based on the mapping index determined from the indication index received at S1220, the mapping index may be determined from

Selecting among a plurality of PUCCH resource sets (a first PUCCH resource set and a third PUCCH resource set)

And one PUCCH resource.

Number of candidate PUCCH resources

May be equal to the selected PUCCH resource set (example of fig. 13) or may be smaller than the selected PUCCH resource set (example of fig. 14).

At S1250, UCI may be transmitted on at least one PUCCH resource of the plurality of PUCCH resources determined at S1240.

Fig. 15 shows another HARQ-ACK feedback process 1500 according to an embodiment of the present disclosure. In process 1500, a plurality of PUCCH resources are provided for HARQ-ACK feedback based on a selected PUCCH resource set including a PUCCH resource candidate set, each PUCCH resource candidate set including a plurality of PUCCH resource IDs. Process 1500 may be performed by UE110 and system 100 is used to explain process 1500.

As shown in fig. 15, process 1500 may begin at S1501, end at S1599, and include steps from S1510 to S1550. Compared to the process 600 in the example of fig. 6, steps S1520-S1530 may be similar to steps S620-S630, while steps S1510 and S1540 through S1550 are different from steps S610 and S640 through S650. The differences between process 600 and process 1500 are highlighted by underlining in fig. 15.

In particular, some of the PUCCH resource sets may each include a resource list that includes a set of PUCCH resource candidate sets instead of PUCCH resource IDs. Each PUCCH resource candidate set may include a plurality of PUCCH IDs.

At S1540, a PUCCH resource candidate set may be determined from the resource list in the PUCCH resource set determined at S1530, based on the indication index received at S1520. Subsequently, multiple PUCCH resources in the PUCCH resource candidate set may be used for HARQ-ACK feedback.

Accordingly, a plurality of PUCCH resources indicated by the selected PUCCH resource candidate set may be determined.

At S1550, UCI may be transmitted on at least one PUCCH resource of the plurality of PUCCH resources configured in the PUCCH resource candidate set determined at S1540.

3. Example Process to provide multiple PUCCH resources for HARQ-ACK feedback

Fig. 17 illustrates an example process 1700 of providing multiple PUCCH resources for HARQ-ACK feedback in accordance with some embodiments of the present disclosure. Process 1700 may be performed at UE 110. System 100 is used to illustrate process 1700. The process 1700 may begin at S1701 and proceed to 1710.

At S1710, configuration information for a plurality of PUCCH resources and one or more PUCCH resource sets may be received. Each of the PUCCH resources may be associated with a PUCCH resource ID. For different examples, the configuration information for one or more PUCCH resources may be different.

In a first example, the one or more PUCCH resource sets may each include a unique maximum UCI payload size and a resource list in which a plurality of PUCCH resource IDs are listed.

In a second example, the one or more PUCCH resource sets may each include a unique maximum UCI payload size and a plurality of resource lists each including a plurality of PUCCH resource IDs.

In a third example, the plurality of PUCCH resource sets may each include a resource list in which a plurality of PUCCH resource IDs are listed. However, different members of the plurality of PUCCH resource sets may share the same maximum UCI payload size and thus may be selected together corresponding to the payload of UCI to be reported.

In a fourth example, the one or more PUCCH resource sets may each include a unique maximum UCI payload size and a resource list in which a plurality of PUCCH resource candidate sets are listed. In each PUCCH resource set, a plurality of PUCCH resource IDs are listed.

At S1720, an indication index from a PUCCH resource indicator field in DCI providing a downlink transmission may be received.

At S1730, one or more PUCCH resource sets from the configured PUCCH resource sets may be determined based on a payload size of the UCI to be reported. The UCI may include at least HARQ-ACK feedback for downlink transmissions. Corresponding to the first example, the second example, or the fourth example at S1710, one PUCCH resource set may be determined. For the third example at S1710, multiple PUCCH resource sets may be determined since different PUCCH resource sets may share the same maximum UCI payload size.

At S1740, based on the indication index received at S1720, a plurality of PUCCH resources may be determined from the one or more PUCCH resource sets determined at S1730. In one example, the plurality of PUCCH resources are distributed over different sub-bands.

Corresponding to the first example at S1710, a specific mapping rule indicating an index and a plurality of PUCCH resources on a resource list of the PUCCH resource set determined at S1730 may be employed to determine the plurality of PUCCH resources.

Corresponding to the second example at S1710, a mapping index may first be determined based on the indication index. Then, using the mapping index, a PUCCH resource ID may be selected from each of the plurality of PUCCH resource lists of the PUCCH resource set determined at S1730. Alternatively, a PUCCH resource ID may be selected from each of the subsets of the plurality of PUCCH resource lists of the PUCCH resource set determined at S1730.

Corresponding to the third example at S1710, a mapping index may first be determined based on the indication index. Then, with the mapping index, a PUCCH resource ID may be selected from each of the plurality of PUCCH resource sets determined at S1730.

Corresponding to the fourth example at S1710, a mapping index may first be determined based on the indication index. Then, using the mapping index, a PUCCH resource candidate set may be selected from the PUCCH resource list of the PUCCH resource set determined at S1730. The PUCCH resource candidate set provides a plurality of PUCCH resource IDs.

At S1750, uci may be transmitted on at least one of the plurality of PUCCH resources determined at S1740-e.g., the plurality of PUCCH resources may be distributed among a set of subbands-UE 110 may perform L BT access procedure to determine which subbands are available-UE 110 may then select one or more of the available subbands to use to transmit uci-process 1700 may then proceed to S1799 and terminate at S1799.

Multiple PUCCH resources for CSI reporting

1. Example of CSI reporting with a single PUCCH resource configured in BWP

In some examples, UE110 may perform CSI reporting according to a CSI reporting configuration. For example, a UE110 that may operate on a carrier is configured with one or more BWPs (e.g., up to four BWPs). Each BWP may be a set of contiguous PRBs selected from the carriers. Each BWP may have a BWP ID, a certain frequency location, a size, a base parameter set (numerology), and a control resource set (CORSET), as configured. Typically, one BWP is active in multiple configured BWPs at a given time. UE110 may not send PUSCH or PUCCH on inactive BWP. The CSI reporting configuration may specify PUCCH resources per BWP for CSI reporting purposes. While operating in active BWP, in response to a request by BS120, UE110 may determine a PUCCH resource configured in active BWP and send a CSI report on the PUCCH resource.

Fig. 18 shows an example of a CSI reporting configuration 1800. The CSI reporting configuration may include a PUCCH CSI resource list 1810. The PUCCH CSI resource list 1810 may include one or more PUCCH CSI resources 1811-1813. Each PUCCH hcsi resource may include a BWP ID and a PUCCH resource ID. It can be seen that a PUCCH resource represented by a corresponding PUCCH resource ID is configured for each BWP represented by a BWP ID.

Fig. 19 shows an example process 1900 for providing PUCCH resources for CSI reporting. Process 1900 may be performed at UE 110. System 100 is used to illustrate process 1900. Process 1900 may begin at S1901 and proceed to 1910.

At S1910, configuration information for CSI reporting may be received. The configuration information may include a PUCCH CSI resource list containing one or more PUCCH CSI resources in the component carrier. Each PUCCH CSI resource specifies a PUCCH resource ID associated with a BWP ID. The configuration information may further include one or more PUCCH resources, each PUCCH resource being associated with a PUCCH resource ID. The configuration information may be signaled from BS120 to UE110, e.g., via one or more messages of RRC signaling.

UE110 may operate on a carrier that is divided into multiple BWPs. Each BWP may be associated with a BWP ID indicated in the PUCCH CSI resource list. Accordingly, based on the received PUCCH CSI resource, a PUCCH resource may be determined for each BWP of the carrier using a corresponding BWP ID.

BS120 may request UE110 to perform CSI reporting, e.g., through RRC, MAC CE, or DCI signaling. The request from BS120 may specify the timing for CSI reporting. Alternatively, the request from BS120 may specify a timing sequence for UE110 to periodically perform CSI reporting.

At S1920, a BWP ID of an active BWP in the carrier may be determined to perform CSI reporting.

At S1930, PUCCH CSI resources may be determined from the PUCCH CSI resource list received at S1910 based on the BWP ID determined at S1920.

At S1940, UCI including at least CSI report may be transmitted on PUCCH resources configured in the PUCCH CSI resources determined at S1930. Process 1900 may then proceed to S1999 and terminate at S1999.

2. Example of providing multiple PUCCH resources in BWP for CSI reporting

Fig. 20 illustrates a CSI reporting process 2000 in accordance with an embodiment of the disclosure. In process 2000, the plurality of PUCCH resources in BWP are provided for CSI reporting based on a PUCCH CSI resource list in which a plurality of PUCCH resource IDs are associated with one BWP. Process 2000 may be performed by UE110 and system 100 is used to explain process 2000.

As shown in fig. 20, the process 2000 starts at S2001 and ends at S2099, and includes steps from S2010 to S2040. Steps S2020 to S2030 may be similar to steps S1920 to S1930 in the example of fig. 19, respectively. However, step S2010 and step S2040 are different from step S1910 and step S1940. The differences between process 1900 and process 2000 are highlighted by underlining in fig. 20.

Specifically, at S2010, configuration information for CSI reporting may be received. The configuration information may include a resource list including one or more PUCCH CSI resources in a carrier. In particular, for each PUCCH CSI resource, a plurality of PUCCH resource IDs are designated as being associated with the BWP ID. These BWP IDs may correspond to BWPs divided from carriers.

Fig. 21 shows an example CSI reporting configuration 2100 in which multiple PUCCH resources are configured for one BWP. As shown, in CSI reporting configuration 2100, PUCCH CSI resource list 2110 includes a plurality of PUCCH CSI resources 2111-2113. Each of the PUCCH CSI resources 2111-2113 includes a BWP ID and a plurality of PUCCH resource IDs.

At S2040, UCI including at least CSI reports may be transmitted on at least one of a plurality of PUCCH resources configured in the PUCCH CSI resources determined at S2030. for example, the plurality of PUCCH resources may be distributed among a plurality of subbands of an active BWP on which the UE110 operates the UE110 may perform L BT access procedure to determine which subbands are available.

Fig. 22 shows another CSI reporting process 2200 according to an embodiment of the present disclosure. In process 2200, a plurality of PUCCH resources are provided for CSI reporting based on a CSI reporting configuration comprising a plurality of PUCCH CSI resource lists. Process 2200 may be performed by UE110 and system 100 is used to explain process 2200.

As shown in fig. 22, process 2200 may begin at S2201, end at S2299, and include steps from S2210 to S2240. Step S2220 may be similar to step S1920 in the example of fig. 19, respectively. However, steps S2210 and S2230-S2240 are different from steps S1910 and S1930-S1940. The differences between process 1900 and process 2200 are highlighted by underlining in fig. 22.

Specifically, at S2210, configuration information for CSI reporting may be received. In particular, the configuration information may include a plurality of resource lists, each resource list including one or more PUCCH CSI resources in the same carrier. Each PUCCH hcsi resource includes a BWP ID and a PUCCH resource ID. These BWP IDs may correspond to BWPs divided from carriers.

Fig. 23 shows an example of a CSI reporting configuration 2300 comprising a plurality of PUCCH CSI resource lists 2310 and 2330. Each PUCCI resource list may include one or more PUCCH CSI resources. Each PUCCH CSI resource may specify one PUCCH resource ID associated with a BWP ID. In addition, the same BWP ID may be indicated in different PUCCH CSI resource lists. For example, the BWP IDs in the PUCCH CSI resources 2311-2313 of the PUCCH CSI resource list 2310 may be respectively the same as the BWP IDs in the PUCCH CSI resources 2321-2323 of the PUCCH CSI resource list 2320. Under such a configuration, for one active BWP ID, a plurality of PUCCH resource IDs may be determined from a plurality of PUCCH CSI resource lists.

At S2230, a plurality of PUCCH CSI resources may be determined from the plurality of resource lists based on the BWP ID determined at S2220. For example, the plurality of PUCCH CSI resources each include the same BWP ID. Accordingly, a plurality of PUCCH resource IDs among the plurality of PUCCH CSI resources may be identified.

At S2240, UCI including at least a CSI report may be transmitted on at least one PUCCH resource of the plurality of PUCCH resources configured among the plurality of PUCCH CSI resources determined at S2230. Similarly, multiple PUCCH resources may be distributed in different subbands. UE110 may select a subset of PUCCH resources for CSI reporting based on the availability of the respective subbands.

3. Example procedure to provide multiple PUCCH resources in BWP for CSI reporting

Fig. 24 illustrates an example process 2400 for providing multiple PUCCH resources for CSI reporting, in accordance with some embodiments of the present disclosure. Process 2400 may be performed at UE 110. System 100 is used to illustrate process 2400. Process 2400 may begin with S2401 and proceed to 2410.

At S2410, configuration information for CSI reports in carriers may be received. The configuration information changes for different examples. In a first example, the configuration information may include one PUCCH CSI resource list including one or more PUCCH CSI resources in a carrier. Each PUCCH CSI resource may include a BWP ID associated with a plurality of PUCCH resource IDs.

Unlike the first example, each PUCCH CSI resource may include a BWP ID associated with one PUCCH resource, and different PUCCH CSI resource lists may indicate the same BWP ID.

At S2420, a BWP ID for an active BWP in the carrier may be determined.

At S2430, one or more PUCCH CSI resources may be determined from the one or more PUCCH CSI resource lists based on the BWP ID. For example, one PUCCH CSI resource indicating an active BWP ID may be determined, corresponding to the first example. Accordingly, a plurality of PUCCH resource IDs indicated in the PUCCH CSI resource may be identified. Corresponding to the second example, multiple PUCCH CSI resources on different PUCCH CSI resource lists and sharing the same active BWP ID may be determined. Accordingly, a plurality of PUCCH resources indicated by a plurality of PUCCH CSI resources may be identified.

At S2440, uci including at least CSI reports may be transmitted on at least one of the plurality of PUCCH resources indicated at S2430. similarly, those PUCCH resources indicated at S2430 may be distributed in different subbands.
