Patent Description:
Document <CIT> discloses a method for transmitting and receiving uplink control information between a terminal and a base station on a physical uplink shared channel (PUSCH) without data (e.g., UL-SCH) and operation of devices supporting the same.

The invention is disclosed by the appended claims.

Transmit processor <NUM> may also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS), a demodulation reference signal (DMRS), and/or the like) and synchronization signals (e.g., the primary synchronization signal (PSS) and secondary synchronization signal (SSS)).

On the uplink, at UE <NUM>, a transmit processor <NUM> may receive and process data from a data source <NUM> and control information (e.g., for reports that include RSRP, RSSI, RSRQ, CQI, and/or the like) from controller/processor <NUM>.

Controller/processor <NUM> of base station <NUM>, controller/processor <NUM> of UE <NUM>, and/or any other component(s) of <FIG> may perform one or more techniques associated with multiplexing uplink control information (UCI) for a UE with multiple antenna panels, as described in more detail elsewhere herein. For example, controller/processor <NUM> of base station <NUM>, controller/processor <NUM> of UE <NUM>, and/or any other component(s) of <FIG> may perform or direct operations of, for example, process <NUM> of <FIG>, process <NUM> of <FIG>, and/or other processes as described herein. Memories <NUM> and <NUM> may store data and program codes for base station <NUM> and UE <NUM>, respectively. In some aspects, memory <NUM> and/or memory <NUM> may include a non-transitory computer-readable medium storing one or more instructions (e.g., code, program code, and/or the like) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, interpreting, and/or the like) by one or more processors of the base station <NUM> and/or the UE <NUM>, may cause the one or more processors, the UE <NUM>, and/or the base station <NUM> to perform or direct operations of, for example, process <NUM> of <FIG>, process <NUM> of <FIG>, and/or other processes as described herein. In some aspects, executing instructions may include running the instructions, converting the instructions, compiling the instructions, interpreting the instructions, and/or the like.

In some aspects, UE <NUM> may include means for determining that a physical uplink control channel (PUCCH) transmitted on a first antenna panel of the UE is to overlap with a physical uplink shared channel (PUSCH) transmitted on a second antenna panel of the UE based at least in part on downlink control information (DCI) scheduling the PUCCH and the PUSCH, means for determining to transmit UCI on one or more of the PUCCH or the PUSCH based at least in part on determining that the PUCCH is to overlap with the PUSCH, means for transmitting the UCI on one or more of the PUCCH or the PUSCH based at least in part on determining to transmit the UCI on one or more of the PUCCH or the PUSCH, and/or the like. In some aspects, such means may include one or more components of UE <NUM> described in connection with <FIG>, such as controller/processor <NUM>, transmit processor <NUM>, TX MIMO processor <NUM>, MOD <NUM>, antenna <NUM>, DEMOD <NUM>, MIMO detector <NUM>, receive processor <NUM>, and/or the like.

In some aspects, base station <NUM> may include means for transmitting first DCI scheduling a PUCCH to be transmitted on a first antenna panel of a UE and second DCI scheduling a PUSCH to be transmitted on a second antenna panel of the UE, where the PUCCH is to overlap with the PUSCH, means for receiving UCI associated with the first DCI and the second DCI on one of the PUCCH or the PUSCH, and/or the like. In some aspects, such means may include one or more components of base station <NUM> described in connection with <FIG>, such as antenna <NUM>, DEMOD <NUM>, MIMO detector <NUM>, receive processor <NUM>, controller/processor <NUM>, transmit processor <NUM>, TX MIMO processor <NUM>, MOD <NUM>, antenna <NUM>, and/or the like.

<FIG> is a diagram illustrating an example <NUM> of a slot format, in accordance with various aspects of the present disclosure. As shown in <FIG>, time-frequency resources in a radio access network may be partitioned into resource blocks, shown by a single resource block (RB) <NUM>. An RB <NUM> is sometimes referred to as a physical resource block (PRB). An RB <NUM> includes a set of subcarriers (e.g., <NUM> subcarriers) and a set of symbols (e.g., <NUM> symbols) that are schedulable by a base station <NUM> as a unit. In some aspects, an RB <NUM> may include a set of subcarriers in a single slot. As shown, a single time-frequency resource included in an RB <NUM> may be referred to as a resource element (RE) <NUM>. An RE <NUM> may include a single subcarrier (e.g., in frequency) and a single symbol (e.g., in time). A symbol may be referred to as an orthogonal frequency division multiplexing (OFDM) symbol. An RE <NUM> may be used to transmit one modulated symbol, which may be a real value or a complex value.

In some telecommunication systems (e.g., NR), RBs <NUM> may span <NUM> subcarriers with a subcarrier spacing of, for example, <NUM> kilohertz (kHz), <NUM>, <NUM>, or <NUM>, among other examples, over a <NUM> millisecond (ms) duration. A radio frame may include <NUM> slots and may have a length of <NUM>. However, a slot length may vary depending on a numerology used to communicate (e.g., a subcarrier spacing, a cyclic prefix format, and/or the like). A slot may be configured with a link direction (e.g., downlink or uplink) for transmission. In some aspects, the link direction for a slot may be dynamically configured. In some communications systems, such as <NUM> or NR, a UE may transmit a communication to a base station on a physical uplink channel (e. , a PUCCH, a PUSCH, and/or the like) in one or more slots.

<FIG> is a diagram <NUM> showing an example of a downlink (DL)-centric slot or wireless communication structure, in accordance with various aspects of the present disclosure. The DL-centric slot may include a control portion <NUM>. The control portion <NUM> may exist in the initial or beginning portion of the DL-centric slot. The control portion <NUM> may include various scheduling information and/or control information corresponding to various portions of the DL-centric slot. In some configurations, the control portion <NUM> may be a physical downlink control channel (PDCCH), as indicated in <FIG>. In some aspects, the control portion <NUM> may include legacy PDCCH information, shortened PDCCH (sPDCCH) information, a control format indicator (CFI) value (e.g., carried on a physical control format indicator channel (PCFICH)), one or more grants (e.g., downlink grants, uplink grants, and/or the like), and/or the like.

The DL-centric slot may also include a DL data portion <NUM>. The DL data portion <NUM> may sometimes be referred to as the payload of the DL-centric slot.

The DL-centric slot may also include an uplink (UL) short burst portion <NUM>. The UL short burst portion <NUM> may sometimes be referred to as an UL burst, an UL burst portion, a common UL burst, a short burst, an UL short burst, a common UL short burst, a common UL short burst portion, and/or various other suitable terms. In some aspects, the UL short burst portion <NUM> may include one or more reference signals. Additionally, or alternatively, the UL short burst portion <NUM> may include feedback information corresponding to various other portions of the DL-centric slot. For example, the UL short burst portion <NUM> may include feedback information corresponding to the control portion <NUM> and/or the data portion <NUM>. Non-limiting examples of information that may be included in the UL short burst portion <NUM> include an acknowledgement (ACK) signal (e.g., a PUCCH ACK, a PUSCH ACK, an immediate ACK), a negative acknowledgement (NACK) signal (e.g., a PUCCH NACK, a PUSCH NACK, an immediate NACK), a scheduling request (SR), a buffer status report (BSR), a hybrid automatic repeat request (HARQ) indicator, a channel state indication (CSI), a channel quality indicator (CQI), a sounding reference signal (SRS), a demodulation reference signal (DMRS), PUSCH data, and/or various other suitable types of information. The UL short burst portion <NUM> may include additional or alternative information, such as information pertaining to random access channel (RACH) procedures, scheduling requests, and various other suitable types of information.

The foregoing is one example of a DL-centric wireless communication structure, and alternative structures having similar features may exist without necessarily deviating from the aspects described herein.

<FIG> is a diagram <NUM> showing an example of an UL-centric slot or wireless communication structure, in accordance with various aspects of the present disclosure.

The control portion <NUM> in <FIG> may be similar to the control portion <NUM> described above with reference to <FIG>. The UL-centric slot may also include an UL long burst portion <NUM>. The UL long burst portion <NUM> may sometimes be referred to as the payload of the UL-centric slot. The UL portion may refer to the communication resources utilized to communicate UL data from the subordinate entity (e.g., UE) to the scheduling entity (e.g., UE or BS). In some configurations, the control portion <NUM> may be a PDCCH.

The UL-centric slot may also include an UL short burst portion <NUM>. The UL short burst portion <NUM> in <FIG> may be similar to the UL short burst portion <NUM> described above with reference to <FIG>, and may include any of the information described above in connection with <FIG>.

<FIG> illustrates an example <NUM> of transmissions with multiple antenna panels, in accordance with various aspects of the present disclosure.

A UE may use multiple antenna panels for transmission or reception, and each antenna panel may be distinguished from the other antenna panel using different kinds of information. Although an antenna panel or an antenna panel identifier (ID) is used herein for purposes of discussion, the antenna panel may be associated with a set of signals or channels, and correspondingly, the antenna panel ID may be derived or associated with the set of signals or channel IDs. For example, a control resource set (CORESET) may be configured with a CORESET pool index. A first antenna panel may be associated with DCI in a CORESET with a first CORESET pool index value (e.g., <NUM>) and a second antenna panel may be associated with DCI in a CORESET with a second CORESET pool index value (e.g., <NUM>). Other information may be used to distinguish antenna panels. An SRS set ID or SRS resource ID may be associated with the first antenna panel and another SRS set ID or SRS resource ID may be associated with the second antenna panel. A beam ID or beam group ID may be associated with the first antenna panel, and another beam ID or beam group ID may be associated with the second antenna panel.

The beam may be configured with a transmission configuration indication (TCI) state or a spatial filter setting for either downlink reception or uplink transmission, or the beam may be configured with spatial relation information indicated for transmitting uplink signals. In some aspects, the beam may be indicated by a reference signal (RS) such as synchronization signal block (SSB), a channel state information RS (CSI-RS), or an SRS. When a set of beam IDs are configured, a first half of the set of beam IDs may be associated with the first antenna panel, and the second half of the set of beam IDs may be associated with the second antenna panel. When a pair of TCI states are indicated in the DCI, the first TCI state ID in the pair may be associated with the first antenna panel, and the second TCI state ID in the pair may be associated with the second panel.

Other information may be used to indicate antenna panels. For example, an uplink transmit power control configuration may include a close loop index, and a first close loop index value (e.g., <NUM>) may be associated with the first antenna panel and a second close loop index value (e.g., <NUM>) may be associated with the second antenna panel. An antenna port ID or antenna port group ID may be associated with the first antenna panel, and another antenna port ID or antenna port group ID may be associated with the second antenna panel, where the antenna port may include but is not limited to a PUSCH antenna port, an SRS antenna port, and a phase tracking RS antenna port. A DMRS code division multiplexing (CDM) group ID may be associated with the first antenna panel, and another DMRS CDM group ID may be associated with the second antenna panel. A timing advance group (TAG) ID may be associated with the first antenna panel, and another TAG ID may be associated with the second antenna panel. A PUCCH resource ID or resource group ID may be associated with the first antenna panel, and another PUCCH resource ID or resource group ID may be associated with the second antenna panel. When a set of PUCCH resource IDs are configured, the first half of the set of PUCCH resource IDs may be associated with the first antenna panel, and the second half of the set of PUCCH resource IDs may be associated with the second antenna panel. A radio network temporary identifier (RNTI) may be associated with the first antenna panel, and another RNTI may be associated with the second antenna panel. A physical cell identity (PCI) or synchronization signal block (SSB) set ID may be associated with the first antenna panel, and another PCI or SSB set ID may be associated with the second antenna panel. By indicating the signal or channel IDs, the associated panel can be indicated, and the corresponding panel ID can be indicated.

<FIG> shows examples of a UE that is to transmit multiple PUSCHs with a same cell index and or a same starting time. The UE may use spatial division multiplexing (SDM) to transmit PUSCHs (e.g., PUSCH1, PUSCH2 shown in <FIG>) with different transmitted precoding matrix indicators (TPMIs), spatial relation information (SRI), and/or transmission configuration indicator (TCI) for each panel. The UE may use time division multiplexing (TDM) to transmit PUSCH1 before PUSCH2. The UE may use frequency division multiplexing (FDM) to transmit PUSCH1 and PUSCH2 at the same time but in different frequency bands.

<FIG> illustrates an example <NUM> of transmissions with multiple antenna panels, in accordance with various aspects of the present disclosure. <FIG> shows how different CORESET pool indices may be used to differentiate multiple TRPs or multiple antenna panels.

A UE may use multiple panels for transmissions to multiple TRPs or receptions from multiple TRPs. PUCCH/PUSCH collisions from different panels may be avoided by various techniques, and the UE does not expect overlapping PUCCH/PUSCH transmissions toward different TRPs. For PUCCH/PUSCH transmissions toward the same TRP, Release <NUM> multiplexing rules may apply, such as described in connection with <FIG>. In some aspects, PUCCH resources may be associated with CORESETs, and these CORESETs may be used to differentiate between TRPs, in order to determine whether there are overlapping PUCCH/PUSCH transmissions among TRPs. PUSCHs may be associated with TRPs and differentiated by scheduling CORESETs for targeted TRPs. For example, <FIG> shows first DCI, which schedules PUSCH1 or PUCCH1, may be located in CORESET A with CORESET pool index value <NUM>, and second DCI, which schedules PUSCH2 or PUCCH2, may be located in CORESET B with CORESET pool index value <NUM>. In <FIG>, PUxCH1 represents either PUSCH1 or PUCCH1. Therefore, the first DCI may be associated with the first TRP and the second DCI may be associated with the second TRP, and correspondingly, the PUSCH1 or PUCCH1 may be associated with the first TRP and the PUSCH2 or PUCCH2 may be associated with a second TRP.

<FIG> illustrates an example <NUM> of transmissions with multiple antenna panels, in accordance with various aspects of the present disclosure. <FIG> shows joint feedback for a first DCI (DCI1) and a second DCI (DCI2).

If a UE is provided first DCI (DCI1) in a CORESET with a CORESET pool index value of <NUM> and second DCI (DCI2) in a CORESET with a CORESET pool index value of <NUM> (e.g., each of first and second DCI schedules a PDSCH transmission), the UE may provide joint ACK/NACK for both the first DCI associated with the first TRP and the second DCI associated with the second TRP, where UCI of ACK/NACK for the first DCI associated with the first TRP and UCI of ACK/NACK for the second DCI associated with the second TRP are transmitted jointly in one uplink channel. If the first DCI associated with the first TRP is for scheduling PUSCH, and the second DCI associated with the second TRP is for scheduling PUCCH, the UE may transmit the UCI of ACK/NACK associated with different TRPs in a single uplink channel, either by the PUSCH, or by the PUCCH. For example, PUxCH1 in <FIG> represents UCI is transmitted on either PUSCH1 or PUCCH1.

The UE may transmit on uplink channels using multiple panels. For example, the UE may transmit the UCI associated with both TRPs on a joint PUCCH from any of the multiple panels of the UE. The UE may also transmit on one or more PUSCHs from one or more of the multiple panels. The UE may have to transmit UCI on one or more these uplink channels. However, it has not been specified on which channel or channels the UE is to transmit the UCI when there are PUCCH/PUSCH transmissions on multiple panels. Without clear directions for UCI transmission in association with transmission on multiple panels, the UE may not effectively communicate UCI to a base station and scheduling may suffer. As a result, communications may become degraded.

According to various aspects described herein, a UE may be configured with instructions for transmitting UCI if PUCCH and PUSCH is transmitted on multiple panels. For example, the UE may have stored configuration information (e.g., associated with a standard) with instructions that direct the UE with how to transmit the UCI. The UE may also provide a UE capability information to a base station, and the base station may provide the instructions in a radio resource control (RRC) configuration message based at least in part on the UE capability information.

The UE may determine that a PUCCH transmitted on a first antenna panel of the UE is to overlap with a PUSCH transmitted on a second antenna panel of the UE based at least in part on DCI scheduling the PUCCH and the PUSCH. The UE may provide feedback to the base station in UCI, to help the base station determine whether downlink transmissions are received and/or learn of conditions related to receiving the transmissions. The UCI may include any of the ACK/NACK information, CSI report information and the scheduling request information. The UE may determine to transmit UCI on one or more of the PUCCH or the PUSCH when the PUCCH and the PUSCH overlap in time. For example, the UE may transmit UCI on the PUSCH and not on the PUCCH. If the PUCCH is a joint PUCCH which transmits UCI associated with different TRPs and overlaps with a PUSCH, the UE may transmit UCI associated with different TRPs on the joint PUCCH instead of on the PUSCH. A base station that transmitted the DCI may know how the UE is configured to transmit UCI and may receive the UCI based at least in part on how the UE is configured to transmit the UCI. Having received the UCI, the base station is able to schedule uplink channel transmissions. As a result, the UE and the base station avoid degraded communications for transmissions on the multiple panels of the UE.

<FIG> illustrates an example <NUM> of multiplexing UCI for a UE with multiple antenna panels, in accordance with various aspects of the present disclosure. <FIG> shows three options for UCI transmission involving a joint PUCCH.

Option <NUM> shows first DCI and second DCI scheduling on a joint PUCCH and a PUSCH that are to overlap in time. Uplink transmissions on the first panel of the UE are shown in <FIG> as a dark box, uplink transmissions on the second panel of the UE are shown as a white box with a solid line, and a joint PUCCH is shown with a shaded box. The cancelled uplink transmission is shown as a dashed line box. For this option, when a joint PUCCH with UCI associated with different TRPs overlaps with a PUSCH, the UE may transmit UCI for both the first DCI associated with the first TRP and for the second DCI associated with the second TRP on the overlapped PUSCH, the UE may not transmit UCI on the joint PUCCH and may cancel the PUCCH transmission.

Option <NUM>-<NUM> shows first DCI and second DCI scheduling a joint PUCCH and a PUSCH (PUSCH1) that are to overlap in time. Another PUSCH (PUSCH2) is scheduled but PUSCH2 does not overlap with the joint PUCCH. For this option, when a joint PUCCH with UCI associated with both the first DCI associated with the first TRP and the second DCI associated with the second TRP overlaps with a PUSCH, the UE may transmit UCI on the joint PUCCH, and the UE may cancel the PUSCH transmissions. The UE may not cancel PUSCH2 since PUSCH2 does not overlap with the joint PUCCH.

Option <NUM>-<NUM> shows first DCI and second DCI scheduling a joint PUCCH and a PUSCH that are to overlap in time. For this option, the UE may be enabled to simultaneously transmit PUCCH and PUSCH, and the UE may transmit UCI on the joint PUCCH and on the PUSCH.

In some aspects, each of the options may use a separate UE capability report and a separate RRC configuration. For example, the UE may indicate a UE capability for Option <NUM>, a UE capability for Option <NUM>-<NUM>, and/or a UE capability for Option <NUM>-<NUM>. Correspondingly, the UE may receive an RRC configuration message for Option <NUM>, an RRC configuration message for Option <NUM>-<NUM>, and/or an RRC configuration message for Option <NUM>-<NUM>.

<FIG> illustrates an example <NUM> of multiplexing UCI for a UE with multiple antenna panels, in accordance with various aspects of the present disclosure. <FIG> shows three more options for UCI transmission involving a joint PUCCH. In <FIG>, the UE may have a PUSCH scheduled on each antenna panel.

Option <NUM> shows first DCI and second DCI scheduling a joint PUCCH and PUSCHs (PUSCH1 and PUSCH2) that are to overlap in time. Uplink transmissions on the first panel of the UE are shown in <FIG> as a dark box, uplink transmissions on the second panel of the UE are shown as a white box with a solid line, and joint PUCCH transmissions are shown with a shaded box. The cancelled uplink transmission is shown as a dashed line box. For this option, when a joint PUCCH with UCI for both the first DCI associated with the first TRP and the second DCI associated with the second TRP overlaps with multiple PUSCHs from different antenna panels, the UE may transmit UCI for both PUSCH1 and PUSCH2, and may cancel the joint PUCCH transmission.

Option 3A shows first DCI and second DCI scheduling a joint PUCCH, PUSCH1, and PUSCH2 that are to overlap in time. In some aspects, the UE may transmit UCI on PUSCH1 or PUSCH2 based at least in part on a starting position of each PUSCH. For example, the UE may transmit UCI on whichever PUSCH has an earliest starting symbol. In some aspects, when a joint PUCCH with UCI for both the first DCI associated with the first TRP and the second DCI associated with the second TRP overlaps with multiple PUSCHs from different antenna panels, the UE may transmit UCI on PUSCH1 or PUSCH2 based at least in part on a DMRS CDM group index or a frequency domain resource assignment (FDRA). For example, the UE may transmit UCI on whichever PUSCH has a or DMRS CDM group index lowest FDRA.

Option <NUM> shows first DCI and second DCI scheduling a joint PUCCH and a PUSCH that are to overlap in time. For this option, the UE may transmit UCI on a PUSCH that is associated with the same panel. For example, when a joint PUCCH with UCI for both the first DCI associated with the first TRP and the second DCI associated with the second TRP overlaps with multiple PUSCHs from different antenna panels, the UE may transmit UCI for the first DCI associated with the first TRP (e.g., UCI1) on PUSCH1, which is associated with the first panel because the first TRP may be associated with the first panel. UE may transmit UCI for the second DCI associated with the second TRP (e.g., UCI2) on PUSCH2, which is associated with the second panel because the second TRP may be associated with the second panel.

<FIG> illustrates an example <NUM> of multiplexing UCI for a UE with multiple antenna panels, in accordance with various aspects of the present disclosure. As shown in <FIG>, example <NUM> includes communication between a base station (BS) <NUM> (e.g., a BS <NUM> depicted in <FIG> and <FIG>) and a UE <NUM> (e.g., a UE <NUM> depicted in <FIG> and <FIG>). In some aspects, base station <NUM> and UE <NUM> may be included in a wireless network such as wireless network <NUM>. Base station <NUM> and UE <NUM> may communicate on a wireless access link, which may include an uplink and a downlink.

As shown by reference number <NUM>, BS <NUM> may transmit first DCI scheduling a PUCCH to be transmitted on a first panel of UE <NUM> and second DCI scheduling a PUSCH to be transmitted on a second panel of UE <NUM>. In some aspects, the first DCI may be transmitted in a first CORESET, and the second DCI may be transmitted in a second CORESET. In some aspects, the second DCI may schedule multiple PUSCHs on multiple panels. In some aspects, the first DCI may schedule a joint PUCCH.

As shown by reference number <NUM>, UE <NUM> may determine that the PUCCH is to overlap with the PUSCH based at least in part on the first DCI and the second DCI. UE <NUM> may determine that the PUCCH is to overlap with the PUSCH based at least in part on a result of comparing resources that are assigned to the PUCCH and resources that are assigned to the PUSCH. If one or more of the resources align in time, frequency, and/or space, the PUCCH and the PUSCH are considered to overlap.

As shown by reference number <NUM>, UE <NUM> may determine to transmit UCI on the PUCCH and/or the PUSCH based at least in part on determining that the PUCCH is to overlap with the PUSCH. The UCI may provide feedback to BS <NUM> to help BS <NUM> determine whether downlink transmissions are received and/or feedback about conditions related to receiving the transmissions. UE <NUM> may determine on which channels to transmit UCI based at least in part on one or more of the aspects described in connection with <FIG> and/or <NUM>. For example, UE <NUM> may receive DCI that schedules the UE to transmit a PUCCH on both the first panel and the second panel, which may be a joint PUCCH. UE <NUM> may determine to transmit UCI on the PUSCH and not on the joint PUCCH, based at least in part on a configuration for transmitting UCI. UE <NUM> may obtain the configuration from stored configuration information or from an RRC message from BS <NUM>. In some aspects, UE <NUM> may transmit UCI on the joint PUCCH and not on the PUSCH.

As shown by reference number <NUM>, UE <NUM> may transmit the UCI, associated with the first DCI and the second DCI, based at least in part on which channels UE <NUM> determined for the UCI. BS <NUM> may receive the UCI and schedule future transmissions on the PUCCH and/or on the PUSCH.

Example process <NUM> is an example where the UE (e.g., UE <NUM>, UE <NUM> depicted in <FIG>, and/or the like) performs operations associated with UCI multiplexing for multiple panels.

As shown in <FIG>, in some aspects, process <NUM> may include determining that a PUCCH transmitted on a first antenna panel of the UE is to overlap with a PUSCH transmitted on a second antenna panel of the UE based at least in part on DCI scheduling the PUCCH and the PUSCH (block <NUM>). For example, the UE (e.g., using receive processor <NUM>, transmit processor <NUM>, controller/processor <NUM>, memory <NUM>, and/or the like) may determine that a PUCCH transmitted on a first antenna panel of the UE is to overlap with a PUSCH transmitted on a second antenna panel of the UE based at least in part on DCI scheduling the PUCCH and the PUSCH, as described in connection with <FIG>.

As further shown in <FIG>, in some aspects, process <NUM> may include determining to transmit UCI on one or more of the PUCCH or the PUSCH based at least in part on determining that the PUCCH is to overlap with the PUSCH (block <NUM>).

For example, the UE (e.g., using receive processor <NUM>, transmit processor <NUM>, controller/processor <NUM>, memory <NUM>, and/or the like) may transmit the UCI on one or more of the PUCCH or the PUSCH based at least in part on determining to transmit the UCI on one or more of the PUCCH or the PUSCH, as described above in connection with <FIG>.

In a first aspect, the PUCCH is a joint PUCCH transmitted by both the first antenna panel and the second antenna panel.
