The UE also determines the plurality of PUCCH resources from the plurality of second resource lists in the second PUCCH resource set based on the received index. In one example, each PUCCH resource of the plurality of PUCCH resources is from a different second of the plurality of second resource lists A list of resources, and associated with the received index.

In one embodiment, the UE receives configuration information each including one or more PUCCH resource sets in the third resource list, wherein at least two PUCCH resource sets in the one or more PUCCH resource sets are configured to have the same maximum UCI The payload size, and based on the payload size of the UCI including the HARQ-ACK feedback for the downlink transmission, determine a plurality of third PUCCH resource sets from the configured one or plurality of PUCCH resource sets, wherein the plurality of third PUCCH resource sets Resource sets have the same maximum UCI payload size. The UE may also determine the plurality of PUCCH resources from the plurality of third resource lists in the plurality of third PUCCH resource sets based on the received index. In one example, each PUCCH resource 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 each including one or a plurality of PUCCH resource sets in a fourth resource list, each fourth resource list includes a plurality of PUCCH resource candidate sets, and each PUCCH resource candidate set includes a plurality of PUCCH resource candidate sets PUCCH resources. The UE may also determine a fourth PUCCH resource set from the configured one or more PUCCH resource sets based on the payload size of the UCI including the HARQ-ACK feedback for the downlink transmission. The UE may also determine the first PUCCH resource candidate set from the fourth resource list in the determined fourth PUCCH resource set based on the received index, the plurality of PUCCH resources included in the first PUCCH resource candidate set being the determined complex number PUCCH resources.

I. Multiple PUCCH resources for UCI reporting

FIG. 1 illustrates a wireless communication system 100 in accordance with some embodiments of the present invention. System 100 may include user equipment (UE) 110 and base station (BS) 120 . In some examples, system 100 employs a fifth generation (5G) new radio (NR) air interface developed by the 3rd Generation Partnership Project (3GPP). In some examples, system 100 employs other wireless Communication Technology. In some examples, system 100 employs non-standardized wireless communication technology.

In some examples, BS 120 may be a base station implementing a gNB node specified in the 5G NR air-interface standard developed by 3GPP. In one example, BS 120 may be configured to control one or more antenna arrays to form directional Tx or Rx beams for transmitting or receiving wireless signals. The UE 110 may be a mobile phone, a laptop computer, an in-vehicle mobile communication device, a 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 the BS 120 and the UE 110, the BS 120 and the UE 110 can communicate with each other according to the corresponding communication protocol.

In various embodiments, UE 110 may send (or report) uplink control information (UCI) on a physical uplink control channel (PUCCH) to support data on a downlink transmission channel or an uplink transmission channel transmission. The UCI may include a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) for receipt of a Downlink Shared Channel (DL-SCH) transport block (or transport sub-block when using Code Block Grouping (CBG)), Downlink scheduling uses channel status information (CSI) on downlink channel conditions and scheduling requests (SRs) indicating that the UE 110 needs uplink resources for uplink shared channel (UP-SCH) transmission.

The UCI may be sent on PUCCH resources specially allocated for PUCCH transmission. For example, PUCCH resources may be frequency and time domain physical transmission resources, such as resources of a plurality of symbols and a plurality of physical resource blocks (PRBs) on an Orthogonal Frequency Division Multiplexing (OFDM) resource grid.

In an example (not shown in Figure 1), BS 120 may configure UE 110 with one PUCCH resource corresponding to the UCI to be transmitted. This configuration may be performed, for example, through radio resource control (RRC) signaling, medium access (MAC) layer control elements (CE), downlink control information, or a combination thereof. Assuming that the system 100 operates on licensed spectrum, the configured PUCCH resources can easily be used by the UE 110 . However, when licensed spectrum is introduced into system 100, the The configuration of a single PUCCH resource for UCI reporting may be unreliable.

FIG. 2A shows the system 100 operating on an unlicensed band 201 . The unlicensed frequency band 201 is divided into a plurality of sub-bands from 210 to 213, each sub-band having, for example, a bandwidth of 20 MHz. BS 120 may configure PUCCH resources 220 to UE 110 for transmission of UCI. Before transmitting the UCI, the UE 110 may perform an access procedure (such as a listen-before-talk (LBT) access procedure) on each sub-band 210-213 to determine whether the sub-band 210-213 is available. As shown, the LBT access process may fail on sub-bands 211 and 213 due to detection of transmission activity by another transmitter in sub-bands 211 and 213. Conversely, since no transmission activity is detected in sub-bands 210 and 212, the LBT access process may be successful on sub-bands 210 and 212. Therefore, transmission is allowed on sub-bands 210 and 212, while transmission is not allowed on sub-bands 211 and 213. Subbands 210-213 may be referred to as LBT subbands when LBT access procedures are performed prior to accessing those subbands.

The PUCCH resource 220 can be pre-scheduled by the BS 120 without knowing whether the corresponding sub-band 211 is available when the PUCCH 220 is to be transmitted. When the sub-band 211 is determined to be unavailable, the transmission of the PUCCH resource 220 may have to be abandoned. When operating on unlicensed spectrum 201, failure to return important information (eg, HARQ-ACK) can degrade the performance of system 100.

To improve reliability of UCI reporting on sub-bands, in some examples, a plurality of PUCCH resources may be configured for one UCI transmission. FIG. 2B shows a situation where a plurality of candidate PUCCH resources 230-233 distributed in different sub-bands 210-213, respectively, are arranged. As shown, candidate PUCCH resources 230 and 232 may be used for UCI reporting when subbands 210 and 212 are available due to LBT access procedures. UE 110 may select a PUCCH resource (eg, PUCCH resource 230) from candidate PUCCH resources 230 and 232 to perform UCI transmission.

Figure 1 shows the UCI reporting process 130 corresponding to the situation of Figure 2B. In a first step 131 of the process 130, the configuration information of the plurality of PUCCH resources 230-233 may be signaled from the BS 120 to the UE 110 through one or more signaling transfers. Depends on what to send from UE to BS 120 The content of the corresponding UCI reported (eg, HARQ-ACK or CSI) and the method used for UCI reporting may provide different configurations in step 131 . UE 110 may determine or obtain a plurality of PUCCH resources 230-233 accordingly. In the second step 132, the UE 110 may send the UCI on a PUCCH resource selected from the plurality of PUCCH resources 230-233 configured in the first step 131 based on the result of the LBT access procedure.

The sub-bands 210 - 213 in the example of FIGS. 2A-2B may be included in a bandwidth part (BWP) or component carrier configured to the UE 110 . In other examples, sub-bands 210-213 may each be configured as component carriers and combined using a carrier aggregation scheme. In other examples, a scheme of multiple PUCCH resources for UCI reporting may be configured on carriers in the licensed spectrum. Under such a configuration, no LBT process is performed before subbands are accessed, and various PUCCH resources at different frequency and time locations can be provided to improve the reliability of UCI reporting.

II. Plural PUCCH resources for HARQ-ACK feedback

1. Example of HARQ-ACK feedback using 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 the PUCCH resource ID 321, the starting PRB 322 in the frequency domain, the resource format 323, and possibly other parameters. The resource format configuration 330 (corresponding to the resource format 323 indicated by the PUCCH resource configuration) may indicate the start symbol 331, the number of PRBs 332 (optional), the number of symbols 333 (optional), and other possible 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, PUCCH resource 301 has a PUCCH resource ID of #2, starting from PRB #4 until PRB #11 (for 8 PRBs), and starting from symbol #2 until symbol #7 (for 6 symbols) in the frequency domain. As shown in the figure, through the PUCCH resource configuration, the PUCCH resources in the frequency domain and the time domain can be identified.

Figure 4 shows an example of a PUCCH resource set configuration 400 for HARQ-ACK feedback. As shown, PUCCH resource set configuration 400 may indicate a number (eg, 4) of PUCCH resource sets (eg, tagged with #1, #2, etc.). Each PUCCH resource set used for HARQ-ACK reporting may typically include information on a PUCCH resource set ID (401), a unique maximum UCI payload size (402) (eg, 2 bits, 10 bits, or 40 bits) and a resource list (403) including one or more PUCCH resource IDs. In the example of Figure 4, the maximum UCI payload size information (402) is indicated in the form of the maximum payload size minus 1 (represented by maxPayloadMinus1). From the PUCCH resource ID, the PUCCH resource configuration as described in the example of FIG. 3 can be identified.

Figure 5 shows an example of a process 500 for the UE 110 to determine which PUCCH resource from the selected PUCCH resource set 510 should be used for HARQ-ACK feedback. For example, UE 110 may receive configuration information for the number of PUCCH resource sets (eg, 4). During the first step, the UE 110 may select a PUCCH resource set 510 from the configured PUCCH resource set based on the payload size of the UCI to be sent. For example, the selected PUCCH resource set 510 may indicate the smallest maximum payload size that can accommodate the payload size to be sent among the configured PUCCH resource sets.

During the second step, the UE 110 may select a PUCCH resource (represented by the PUCCH resource ID) from the resource list 511 in the selected PUCCH resource set 510 based on the index from the DCI providing the downlink transmission (referred to as the indication index) ). This selection is illustrated in mapping table 520, where different indices (referred to as mapping indices) are associated with different PUCCH resource IDs.

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

FIG. 6 shows 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 the plurality of PUCCH resources and one or more sets of PUCCH resources may be received at the UE 110 from the BS 120, eg, via RRC signaling. Configuration information may be sent with a separate RRC message.

At S620, an indication index from a PUCCH resource indicator field in the DCI providing downlink transmission may be received. For example, the downlink transmission may be a physical downlink shared channel (PDSCH) transmission or a semi-persistently scheduled (SPS) PDSCH version transmission. The DCI associated with the downlink transmission may indicate the PUCCH resource for the received HARQ-ACK feedback of the downlink transmission by using the PUCCH resource indicator. Additionally, DCI may provide a time offset (eg, in terms of slots or symbols) relative to DCI or downlink transmissions to indicate the timing of PUCCH resources for HARQ-ACK feedback.

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

In some examples, BS 120 may request UE 110 to provide CSI reports along with HARQ-ACK feedback for specific downlink transmissions, which may increase the UCI payload size. Additionally, UE 110 may need to send an SR to request uplink transmission resources. SR can also be included in UCI.

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

At S640, the PUCCH resource 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 the mapping index to the PUCCH resource list in the PUCCH resource set determined at S630.

At S650, the UCI may be sent 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 a plurality of PUCCH resources suitable for different types of PUCCH structures. For example, compared to Long Term Evolution (LTE), a more flexible PUCCH structure is defined in NR to target different applications and use cases. The NR PUCCH structure can have a short or long duration. The short duration PUCCH may span 1 or 2 symbols in a slot and is multiplexed with the downlink or uplink data channel in a time division multiplexing (TDM) manner. For example, a short duration PUCCH can be inserted into the last part of a slot to achieve fast HARQ-ACK feedback. Conversely, long-duration PUCCHs may span from 4 to 11 symbols and are multiplexed in time slots in a frequency division multiplexing (FDM) manner. Therefore, a long-duration PUCCH may provide sufficient coverage and robustness required for some use cases.

Therefore, in step S620, the BS 120 may determine the indication index corresponding to the PUCCH resource based on the corresponding PUCCH structure suitable for the specific application and optionally other parameters (eg, channel conditions, UE capabilities, etc.). The indication index is then provided to UE 110.

2. An example of providing a plurality of PUCCH resources for HARQ-ACK feedback

FIG. 7 shows a HARQ-ACK feedback process according to an embodiment of the present invention 700. In process 700, a plurality of PUCCH resources are provided for HARQ-ACK feedback based on a resource mapping rule indexed to PUCCH. Process 700 may be performed by UE 110 and system 100 is used to interpret process 700 .

As shown in FIG. 7, the process 700 starts at S701, ends at S799, and includes steps from S710 to S750. Steps S710 to S730 may be respectively similar to steps S610 to S630 in the example of FIG. 6 . However, steps S740 to S750 are different from steps S640 to S650. The difference between process 600 and process 700 is highlighted in Figure 7 with an underline.

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 an indicated index.

As shown, the selected PUCCH resource set 810 includes a resource list 811 . The number of candidate PUCCH resources may be selected from the resource list 811 based on the mapping table 820 (with

Express). In the example in Figure 8,

Take the value 3. In various examples,

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

At S750, the UCI may be sent on at least one PUCCH resource among the plurality of PUCCH resources determined at S740. For example, the candidate PUCCH resources determined at S740 may be distributed over a plurality of sub-bands. After the LBT access process, a subset of the plurality of sub-bands are available. Therefore, UE 110 may select one or a plurality of candidate PUCCH resources among the available sub-bands for transmission of UCI source.

FIG. 9 illustrates another HARQ-ACK feedback process 900 in accordance with an embodiment of the present invention. In process 900, a plurality of PUCCH resources are provided for HARQ-ACK feedback based on a selected PUCCH resource set comprising a plurality of resource lists. Process 900 may be performed by UE 110 and system 100 is used to interpret process 900 .

As shown in FIG. 9, the process 900 starts at S901, ends at S999, and includes steps from S910 to S950. Compared with 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 difference between process 600 and process 900 is highlighted in Figure 9 with an underline.

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

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

At S1240, based on the indication index received at S1220, the plurality of PUCCH resources may be determined from the 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 resource list of the plurality of resource lists.

Figure 13 shows an example of determining a plurality of PUCCH resources from a plurality of selected PUCCH resource sets 1310-1320. As shown, PUCCH resource sets 1310-1320 may each have information 1311-1322 indicating the same maximum UCI payload size, and thus PUCCH resource sets 1310-1320 are simultaneously selected from the plurality of PUCCH resource sets configured at S1210. The mapping index may be determined according to an indication index that explicitly or implicitly indicates the mapping index. Based on the mapping index and according to the mapping table 1330, two PUCCH resource IDs can be determined from the two selected PUCCH resource sets 1310 and 1320.

Process 1500 may be performed by UE 110 and system 100 is used to interpret process 1500.

As shown in FIG. 15, the process 1500 may start 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-S1550 are different from steps S610 and S640-S650. The difference between process 600 and process 1500 is highlighted in Figure 15 with an underline.

Specifically, at S1510, configuration information of a plurality of PUCCH resources and one or more PUCCH resource sets may be received. 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. Then, a plurality of PUCCH resources in the PUCCH resource candidate set can be used for HARQ-ACK feedback.

Figure 16 shows an example of determining a PUCCH resource candidate set from the selected PUCCH resource set 1610. As shown, the PUCCH resource set 1610 may include a resource list 1611 on which one or more PUCCH resource candidate sets (represented by PUCCH candidate sets) may be listed. Each PUCCH resource candidate set may include a plurality of PUCCH resource IDs. The mapping index in the mapping table 1620 may be determined based on the indication index received at S1520. The indicated index may indicate the mapping index explicitly or implicitly.

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

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

3. Example process for providing a plurality of PUCCH resources for HARQ-ACK feedback

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

At S1710, configuration information of 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 of one or more PUCCH resources may be different.

In a first example, 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, one or more PUCCH resource sets may each include a unique Maximum UCI payload size and resource lists each including PUCCH resource IDs.

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

In a fourth example, one or more PUCCH resource sets may each include a unique maximum UCI payload size and a resource list in which the 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 the DCI providing downlink transmission may be received.

At S1730, one or more PUCCH resource sets from the configured PUCCH resource sets may be determined based on the 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 in S1710, one PUCCH resource set may be determined. For the third example at S1710, since different PUCCH resource sets can share the same maximum UCI payload size, a plurality of PUCCH resource sets can be determined.

At S1740, based on the indication index received at S1720, a plurality of PUCCH resources may be determined from one or a plurality of 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 in S1710, a specific mapping rule between the indication index and the plurality of PUCCH resources on the resource list of the PUCCH resource set determined in S1730 may be employed to determine the plurality of PUCCH resources.

Corresponding to the second example at S1710, the mapping index may be first determined based on the indication index. Then, using the mapping index, a plurality of PUCCH resource sets determined in S1730 can be obtained from the A PUCCH resource ID is selected in each PUCCH resource list in the PUCCH resource list. Alternatively, the 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, the mapping index may be determined first based on the indication index. Then, using the mapping index, a PUCCH resource ID can be selected from each PUCCH resource set of the plurality of PUCCH resource sets determined at S1730.

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

At S1750, the UCI may be sent on at least one PUCCH resource among the plurality of PUCCH resources determined at S1740. For example, a plurality of PUCCH resources may be distributed in a set of subbands. UE 110 may perform an LBT access procedure to determine which sub-bands are available. The UE 110 may then select one or a plurality of PUCCH resources in the available sub-bands for transmitting the UCI. The process 1700 may then proceed to S1799 and terminate at S1799.

III. Plural PUCCH resources for CSI reporting

1. An example of CSI reporting using a single PUCCH resource configured in BWP

In some examples, UE 110 may perform CSI reporting in accordance with the CSI reporting configuration. For example, a UE 110 operating on a carrier may be configured with one or more BWPs (eg, up to four BWPs). Each BWP may be a contiguous set of PRBs selected from the carrier. As configured, each BWP may have a BWP ID, a certain frequency location, size, a base parameter set (numerology) and a control resource set (CORSET). Typically, one BWP is active among multiple configured BWPs at a given time. UE 110 may not transmit PUSCH or PUCCH on an inactive BWP. For CSI reporting purposes, the CSI reporting configuration may specify PUCCH resources per BWP. when in active BWP In operation, in response to the request of the BS 120, the UE 110 may determine the PUCCH resource configured in the active BWP, and send a CSI report on the PUCCH resource.

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

Figure 19 illustrates 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 S1910.

At S1910, configuration information for CSI reporting may be received. The configuration information may include a PUCCH CSI resource list including one or a plurality of PUCCH CSI resources among the component carriers. Each PUCCH CSI resource specifies the PUCCH resource ID associated with the BWP ID. The configuration information may further include one or more PUCCH resources, and each PUCCH resource is associated with a PUCCH resource ID. The configuration information may be signaled from the BS 120 to the UE 110, eg, through one or more messages of RRC signaling.

UE 110 may operate on a carrier divided into a plurality of BWPs. Each BWP may be associated with a BWP ID indicated in the PUCCH CSI resource list. Therefore, based on the received PUCCH CSI resources, the PUCCH resources can be determined for each BWP of the carrier using the corresponding BWP ID.

BS 120 may request UE 110 to perform CSI reporting, eg, through RRC, MAC CE, or DCI signaling. The request from BS 120 may specify timing for CSI reporting. Alternatively, the request from BS 120 may specify a timing sequence for UE 110 to periodically perform CSI reporting.

At S1920, the BWP ID of the active BWP in the carrier can be determined to perform CSI Report.

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

At S1940, the UCI including at least the CSI report may be sent on the PUCCH resource configured in the PUCCH CSI resource determined at S1930. Then, the process 1900 may proceed to S1999 and terminate at S1999.

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

Figure 20 illustrates a CSI reporting process 2000 in accordance with an embodiment of the present invention. In process 2000, a plurality of PUCCH resources in a BWP are provided for CSI reporting based on a PUCCH CSI resource list in which a plurality of PUCCH resource IDs are associated with a BWP. Process 2000 may be executed by UE 110 and system 100 is used to interpret process 2000.

As shown in FIG. 20, the process 2000 starts at S2001, ends at S2099, and includes steps from S2010 to S2040. Steps S2020 to S2030 may be respectively similar to steps S1920 to S1930 in the example of FIG. 19 . However, steps S2010 and S2040 are different from steps S1910 and S1940. The difference between Process 1900 and Process 2000 is highlighted in Figure 20 with an underline.

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

Figure 21 shows an example CSI reporting configuration 2100 in which a plurality of 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.

In S2030, when the PUCCH CSI resources are determined from the resource list configured in S2010, a plurality of PUCCH resources indicated by the PUCCH CSI resources may be determined.

In S2040, the UCI including at least the CSI report may be sent on at least one PUCCH resource among the plurality of PUCCH resources configured in the PUCCH CSI resource determined in S2030. For example, a plurality of PUCCH resources may be distributed among a plurality of sub-bands of the active BWP on which the UE 110 operates. UE 110 may perform an LBT access procedure to determine which sub-bands are available. The UE 110 may then select one or more of the PUCCH resources in the available sub-bands for transmitting the UCI. Additionally, the UCI may include the SR when the UE 110 needs uplink resources for data transmission.

Figure 22 illustrates another CSI reporting process 2200 in accordance with an embodiment of the present invention. In process 2200, a plurality of PUCCH resources are provided for CSI reporting based on a CSI reporting configuration that includes a plurality of PUCCH CSI resource lists. Process 2200 may be executed by UE 110 and system 100 is used to interpret process 2200.

As shown in FIG. 22, the process 2200 may start 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, step S2210 and steps S2230-S2240 are different from steps S1910 and steps S1930-S1940. The difference between process 1900 and process 2200 is highlighted in Figure 22 with an underline.

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

Figure 23 shows an example of a CSI reporting configuration 2300 including a plurality of PUCCH CSI resource lists 2310-2330. Each PUCCI resource list may include one or more PUCCHs CSI resources. Each PUCCH CSI resource may specify one PUCCH resource ID associated with the 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 the same as the BWP IDs in the PUCCH CSI resources 2321-2323 of the PUCCH CSI resource list 2320, respectively. Under such a configuration, for one active BWP ID, a plurality of PUCCH resource IDs can 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, each of the plurality of PUCCH CSI resources includes the same BWP ID. Therefore, a plurality of PUCCH resource IDs among a plurality of PUCCH CSI resources can be identified.

In S2240, the UCI including at least the CSI report may be sent on at least one PUCCH resource among the plurality of PUCCH resources configured in the plurality of PUCCH CSI resources determined in S2230. Similarly, a plurality of PUCCH resources may be distributed in different sub-bands. UE 110 may select a subset of PUCCH resources for CSI reporting based on the availability of various subbands.

3. Example process of providing a plurality of PUCCH resources in BWP for CSI reporting

Figure 24 illustrates an example process 2400 for providing a plurality of PUCCH resources for CSI reporting in accordance with some embodiments of the present invention. Process 2400 may be performed at UE 110 . System 100 is used to illustrate process 2400. Process 2400 may start at S2401 and proceed to S2410.

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

In a second example, the configuration information may include a plurality of PUCCH CSI resource lists, each of which includes one or a plurality of PUCCH CSI resources among the carriers. 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, the BWP ID of the active BWP in the carrier can 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, corresponding to the first example, one PUCCH CSI resource indicating one of the active BWP IDs may be determined. Therefore, a plurality of PUCCH resource IDs indicated in the PUCCH CSI resource can be identified. Corresponding to the second example, a plurality of PUCCH CSI resources on different PUCCH CSI resource lists and sharing the same active BWP ID may be determined. Therefore, a plurality of PUCCH resources indicated by a plurality of PUCCH CSI resources can be identified.

At S2440, the UCI including at least the CSI report may be sent on at least one PUCCH resource among the plurality of PUCCH resources indicated at S2430. Similarly, those PUCCH resources indicated at S2430 may be distributed in different sub-bands. UE 110 may perform LBT access procedures and select from a subset of those PUCCH resources in the available subbands. Process 2400 may proceed to S2499 and terminate at S2499.
