       FIG.  1    illustrates a network environment  100  in accordance with some embodiments. The network environment  100  may include a UE  104  and a gNB  108 . The gNB  108  may be a base station that provides one or more wireless access cells, for example, 3GPP New Radio “NR” cells, through which the UE  104  may communicate with the gNB  108 . The UE  104  and the gNB  108  may communicate over an air interface compatible with 3GPP technical specifications such as those that define Fifth Generation (5G) NR system standards. 
     The gNB  108  may include a gNB controller  112  coupled with one or more TRPs, for example, TRP  116  and TRP  120 . In general, the gNB controller  112  may perform the majority of the operations of a communication protocol stack, including scheduling, while the TRPs  116  and  120  act as distributed antennas. In some embodiments, the TRPs  116  and  120  may perform some lower-level operations of the communication protocol stack (for example, analog physical (PHY) layer operations). 
     The gNB  108  may use the TRPs  116  and  122  to geographically separate points at which a signal may be transmitted to, or received from, the UE  104 . This may increase flexibility of using multiple-input, multiple-output and beamforming enhancements for communicating with the UE  104 . The TRPs  116  and  120  may be used to transmit downlink transmissions to the UE  104  and receive uplink transmissions from the UE  104 . In some embodiments, the distributed transmit/receive capabilities provided by the TRPs  116  and  120  may be used for coordinated multipoint or carrier aggregation systems. 
     The gNB  108  may transmit information (for example, data and control signaling) in the downlink direction by mapping logical channels on the transport channels, and transport channels onto physical channels. The logical channels may transfer data between a radio link control (RLC) and media access control (MAC) layers; the transport channels may transfer data between the MAC and PHY layers; and the physical channels may transfer information across the air interface. 
     The UE  104  and the TRPs  116  may include an array of antenna elements in one or more antenna panels that allow receive or transmit beamforming. Beamforming may improve the uplink and downlink budgets by determining and using uplink and downlink beams that increase antenna gain and overall system performance. The UE  104  and the gNB  108  may determine desired uplink-downlink beam pairs using beam management operations based on reference signal measurements and channel reciprocity assumptions. 
     In the downlink direction, the TRPs  116  and  120  may send synchronization signal blocks (SSBs) and channel state information—reference signals (CSI-RSs) that are measured by the UE  104  to determine the desired downlink beam pair for transmitting/receiving physical downlink control channel (PDCCH) and physical downlink shared channel (PDSCH) transmissions. In some embodiments, the network elements may assume uplink/downlink beam correspondence and use the desired downlink beam pair as the desired uplink beam pair for PUSCH and PUCCH transmissions. In some embodiments, beam pairs may be independently determined for the uplink direction based on sounding reference signals (SRSs) transmitted by the UE  104 . In various embodiments, beam management may include different stages such as initial acquisition of the uplink and downlink beams, and later refinement of the uplink and downlink beams. 
     In addition to beam management, the SRSs may be used for uplink channel-aware scheduling and link adaptation, estimation of the downlink propagation channel when channel reciprocity exists, and both codebook and non-codebook-based transmissions. 
     The PUCCH may be used to transmit uplink control information (UCI) including, for example, hybrid-automatic repeat request (HARQ) acknowledgements, scheduling requests, and periodic and semi-persistent channel state information (CSI) reports. The PUSCH may be used to transfer user data in the user plane and signaling radio bearer (SRB) messages in the control plane. The PUSCH may also be used to transfer various control information such as, for example, buffer status reports, cell-radio network temporary identifiers (C-RNTIs), configured grant configuration, and power headroom reports. 
     As briefly discussed above, Release 15 and 16 of 3GPP provide repetitions of PUCCH and PUSCH in some situations to increase reliability. For example, for the longer PUCCH formats (for example, PUCCH formats  1 ,  3 , and  4 ), the gNB can configure the UE to repeatedly transmit a PUCCH resource in one or more slots. For PUSCH, the gNB can configure the UE to repeatedly transmit the PUSCH with repetition type A or repetition type B. In PUSCH repetition type A, each PUSCH repetition may be mapped to a consecutive slot. For example, a first PUSCH repetition may be mapped to a first slot, a second PUSCH repetition may be mapped to a second slot that immediately follows the first slot, and so on. In PUSCH repetition type B, each PUSCH repetition may be mapped to consecutive symbols. The consecutive symbols may be in one or more slots. In Release 15 and 16, all the repetitions of PUCCH or PUSCH are transmitted from the same beam. 
     Release 17 of 3GPP introduces further enhancement schemes for PUCCH and PUSCH. For example, PUCCH/PUSCH may be transmitted repeatedly within a slot or across slots where different beams may be used for different repetitions. The repetitions of different beams may be transmitted to the same or different TRPs. 
     PUCCH repetitions transmitted on different beams may use different PUCCH resources to transmit the same UCI. The resources configured for the PUCCH repetitions may be in one or more slots. Alternatively, PUCCH repetitions transmitted on different beams may use a PUCCH resource configured with more than one beam. Thus, there may be two ways to implement PUCCH repetition. First, more than one PUCCH resource may be configured to transmit the UCI. Second, more than one beam may be configured for a PUCCH resource that is used to transmit the UCI. The different beams used for transmitting the PUCCH repetitions may be defined by different spatial relations, transmission configuration indicators (TCIs), or power control parameters. 
     PUSCH repetitions transmitted on different beams may use different time/frequency resources configured by RRC or granted by a single downlink control information (DCI) or multiple DCIs to transmit the same PUSCH payload. The resources configured for the PUSCH repetitions may be in one or more slots. The different beams used for transmitting the PUSCH repetitions may be defined by different SRS resource indicators (SRIs), transmission precoder matrix indicators (TPMIs), or power control parameters. 
     In some situations, uplink transmissions may collide with one another. For example, a mapping function in the UE  104  may map first and second uplink transmissions on the same or at least partially overlapping uplink resources. In these situations, the UE  104  may need to perform a collision resolution procedure to determine the transmissions to be sent on the uplink resources. Collision resolution procedures may be defined for a variety of uplink collisions including the following seven specific cases. Case 1 includes a collision between a PUCCH without repetition and a PUSCH with repetition type A. Case 2 includes a collision between a PUCCH without repetition and a PUSCH with repetition type B. Case 3 includes a collision between PUCCH with repetition and PUSCH with repetition of type A or B. Case 4 includes a collision between a PUCCH with repetition and another PUCCH with repetition. Case 5 includes a collision between a PUCCH with repetition and a PUSCH without repetition. Case 6 includes a collision between a PUCCH with repetition and an SRS. Case 7 includes a collision between a PUSCH with repetition and an SRS. 
     Collision resolution procedures for uplink transmissions from a plurality of beams may follow one or more of the following principles. First, it may be desirable to keep UCI transmitted with multi-beam operation to improve reliability. Second, priority of UCI may be based on a target receiving TRP. Third, it may be desirable to transmit UCI based on the correct beam targeting to the corresponding receiving TRP. Various embodiments describe collision resolution procedures influenced by these principles. 
     Collision resolution procedures with respect to case 1—PUCCH without repetition colliding with PUSCH with repetition type A—may be addressed as follows. 
     A first option, driven by the second and third principles described above, may determine uplink transmissions based on target TRPs of the PUCCH and PUSCH. For example, if the PUCCH and the PUSCH are associated with the same TRP (for example, they are to be transmitted to the same TRP), the UCI from the PUCCH may be multiplexed to all of the PUSCH repetitions. If the PUCCH in the PUSCH are not associated with the same TRP, the UE  104  may drop the PUCCH, the PUSCH repetition in overlapped symbols, or all the PUSCH repetitions. The transmissions to be dropped may be based on a priority determined by an associated TRP index.  FIG.  2    illustrates a collision resolution procedure  200  that describe these concepts in accordance with some embodiments. 
     As shown in  FIG.  2   , the UE  104  may receive a PUCCH  204  for transmission on a first beam, for example beam X, and may also receive PUSCH repetitions  208 . The first two PUSCH repetitions, for example, PUSCH repetition #1 and #2, may be scheduled for transmission on beam X, while the last two PUSCH repetitions, for example, PUSCH repetitions #3 and #4, may be scheduled for transmission on beam Y. 
     In the collision resolution procedure  200 , the UE  104  may determine that PUCCH  204  is to collide with PUSCH repetition #1 of PUSCH repetitions  208 . The UE  104  may determine the uplink transmissions based on target TRPs of the PUCCH  204  and the PUSCH repetitions  208 . In some embodiments, the target TRPs may be determined based on control resource set (CORESET) information corresponding to the PDCCH that schedules the PUCCH  204  and the PUSCH repetitions  208 . 
     The gNB  108  may transmit the scheduling PDCCHs using resource elements that belong to a CORESET. A search space configuration may refer to a particular CORESET to define a search space, for example, a specific set of resource blocks and symbols where the UE  104  is to attempt to decode the PDCCH. The gNB  108  may configure up to three CORESETs for an active downlink bandwidth part of a serving cell. The CORESET may be configured by a ControlResourceSet information element that defines frequency domain resources to indicate resource blocks allocated to the CORESET, a duration to indicate a number of symbols allocated to the CORESET (which may be 1, 2, or 3 orthogonal frequency division multiplexing (OFDM) symbols), and quasi-co-location (QCL) information to support a successful reception of the PDCCH. In some embodiments, the gNB  108  may configure one or more CORESET pools to allow TRPs  116  and  120  transmitting PDCCHs that may potentially schedule fully or partially overlapped PUSCHs/PUCCHs in time. To configure the CORESET pools, the gNB  108  may include a CORESET pool index in the ControlResourceSet IE to associate the CORESET with a corresponding CORESET pool. The CORESET pool index may correspond to a TRP index as described herein. In some embodiments, the gNB  108  may configure up to two different CORESET pools. 
     If the PDCCHs that schedule the PUCCH and the PUSCH are associated with the same CORESET pool, for example, they are both associated with the same CORESET pool index, they may be transmitted from the same TRP. Accordingly, the target TRP for the PUCCH (TRP PUCCH ) may be the same as the target TRP for the PUSCH (TRP PUSCH ). In this situation, the UE  104  may multiplex UCI from the PUCCH  204  to all the PUSCH repetitions  208  resulting in PUSCH repetitions of transmission sequence  212 . The PUSCH repetitions of transmission sequence  212  may then be transmitted to the TRP. 
     If TRP PUCCH  is different than TRP PUSCH , the UE  104  may determine the transmission based on a priority of the associated TRP indices, for example, CORESET pool indices. In some embodiments, the CORESET pool index with the lower value may be considered to have a relatively higher priority. 
     In some embodiments, if the priority of TRP PUCCH  (Pri(TRP PUCCH )) is greater than the priority of TRP PUSCH  (Pri(TRP PUSCH )), the UE  104  may choose one of two sub-options. In a first sub-option, the UE  104  may drop the PUSCH repetition that collides with the PUCCH  204 , for example, PUSCH repetition #1, and transmit the remaining repetitions. This is shown as transmission sequence  216  of  FIG.  2   . In a second sub-option, the UE  104  may drop all PUSCH repetitions resulting in transmission sequence  220  that only includes the PUCCH. The UE  104  may use this option upon a determination that the likelihood of a successful transmission of the remaining PUSCH repetitions is less than a predetermined threshold. In this scenario, the use of the transmission resources required to transmit only some of the repetitions may not be justified by the likelihood of success. 
     In some embodiments, if Pri(TRP PUSCH )) is greater than Pri(TRP PUCCH ), the UE  104  may drop the PUCCH  204 . The resulting transmission sequence  224  may then correspond to the PUSCH repetitions  208 . 
     A second option for case 1, driven by the first principle described above, may determine uplink transmissions based on timeline constraints for transmitting UCI. The timeline constraints may be based on configuration information provided by the gNB  108  or processing capability of the UE  104 . For example, if the UCI includes HARQ-ACK information related to a reception of PDSCH, the UE  104  may need a certain amount of time to process the PDSCH and generate the corresponding HARQ-ACK information. Therefore, the UE  104  may not be able to multiplex UCI onto PUSCH repetitions that occur before the time needed for these operations. In some embodiments, the timeline constraints may be consistent with those described in 3GPP Technical Specification (TS) 38.213 v16.2.0 (2020-06). 
       FIG.  3    illustrates a collision resolution procedure  300  that may be used for the second option of case 1 in accordance with some embodiments. Similar to the collision resolution procedure  200 , collision resolution procedure  300  includes a PUCCH  304  that conflicts with a first repetition of PUSCH repetitions  308 . In this embodiment, the UE  104  may determine that: PUSCH repetition #1 is the first PUSCH repetition for the transmit beam X that satisfies the timeline constraints; and PUSCH repetition #2 is the first PUSCH repetition for the transmit beam Y that satisfies the timeline constraints. Therefore, the UE  104  may generate the sequence  312  in which UCI is multiplexed to PUSCH repetition #1 and PUSCH repetition #3. 
     In some embodiments, the second option of case 1 may be used regardless of the associated TRP indices. Alternatively, the second option of case 1 may be employed when both the PUSCH and the PUCCH are directed to the same TRP. Thus, it could be used as an alternative to transmission sequence  212 . 
     Collision resolution procedures for case 2—PUCCH without repetition colliding with PUSCH with repetition type B—may include first and second options that may be similar to those described above with respect to case 1. Case 2 may also include a third option as discussed herein. 
       FIG.  4    includes a collision resolution procedure  400  in accordance with some embodiments. The collision resolution procedure  400  may correspond to a first option for case 2, where a PUCCH without repetition collides with PUSCH with repetition type B. In particular, PUCCH  404  may collide with the first two repetitions of the PUSCH repetitions  408 . Given that the PUSCH repetitions  408  are of a repetition type B, one slot may include more than one repetition. As shown, one slot may include two repetitions. 
     If the PUCCH  404  and the PUSCH repetitions  408  are associated with the same TRP, for example, TRP PUSCH  equals TRP PUCCH , the UE  104  may multiplex UCI from the PUCCH  404  to all the PUSCH repetitions  408  resulting in PUSCH repetitions of transmission sequence  412 . The PUSCH repetitions of transmission sequence  412  may then be transmitted to the TRP. 
     If the PUCCH  404  and the PUSCH repetitions  408  are associated with different TRPs, e.g., If TRP PUCCH  is different than TRP PUSCH , the UE  104  may determine the transmission based on a priority of the associated TRP index, for example a CORESET pool index. In some embodiments, the CORESET pool index with the lower value may be considered to have a relatively higher priority. 
     In some embodiments, if Pri(TRP PUCCH ) is greater than Pri(TRP PUSCH ), the UE  104  may choose one of two sub-options. In a first sub-option, the UE  104  may drop the PUSCH repetitions that collide with the PUCCH  404 , for example, PUSCH repetitions #1 and #2, and transmit the remaining repetitions. This is shown as transmission sequence  416  of  FIG.  4   . In a second option, the UE  104  may drop all PUSCH repetitions resulting in transmission sequence  420  that only includes the PUCCH. 
     In some embodiments, if Pri(TRP PUSCH )) is greater than Pri(TRP PUCCH ), the UE  104  may drop the PUCCH  204 . The resulting transmission sequence  424  may then correspond to the PUSCH repetitions  208 . 
       FIG.  5    illustrates a collision resolution procedure  500  that may be used for the second option of case 2 in accordance with some embodiments. Collision resolution procedure  500  includes a PUCCH  504  that conflicts with first and second repetitions of PUSCH repetitions  508 . In this embodiment, the UE  104  may multiplex the UCI to the first actual PUSCH repetitions among the repetitions that meet the timeline constraint (defined in section 9.2.5 of TS 38.214, for example) with the same beam. As used herein, the first “actual PUSCH” may refer to the first PUSCH transmission that is actually to be transmitted. The UE  104  may determine that: PUSCH repetition #1 is the first PUSCH repetition for the transmit beam X that satisfies the timeline constraints; and PUSCH repetition #3 is the first PUSCH repetition for the transmit beam Y that satisfies the timeline constraints. Therefore, the UE  104  may generate the sequence  512  in which the UCI is multiplexed to PUSCH repetition #1 and PUSCH repetition #3. 
     The collision resolution procedure  500  may be independent of the TRP indices associated with the PUSCH/PUCCH transmissions. Alternatively, the collision resolution procedure  500  may be used when the TRP indices are the same, for example, as an alternative to transmission sequence  412 . 
     In some embodiments, a third option for a collision resolution procedure for case 2, which may also be based on principle 1, may be used. In this option, the UCI may be multiplexed to all the PUSCH repetitions. In various embodiments, this may be based on, or independent from, consideration of target TRPs associated with the PUCCH or PUSCH transmissions. 
     In some embodiments, case 3—PUCCH with repetition colliding with PUSCH with repetition type A or B—may include options 1-3 similar those described above with respect to case 2, for example. 
       FIG.  6    includes a collision resolution procedure  600  in accordance with some embodiments. Collision resolution procedure  600  may be based on principles 2 and 3. 
     The collision resolution procedure  600  may correspond to a first option for case 3, where a PUCCH with repetition collides with PUSCH with repetition type A or B. In particular, PUCCH repetitions  604  may collide with the first two repetitions of the PUSCH repetitions  608 . The PUSCH repetitions  608  are shown with repetition type A, with one repetition per slot; however, similar concepts are also applicable to PUSCH repetitions of type B. 
     If the PUCCH repetitions  604  and the PUSCH repetitions  608  are associated with the same TRP, for example, TRP PUSCH  equals TRP PUCCH , the UE  104  may multiplex UCI from the PUCCH repetitions  604  to all the PUSCH repetitions  608  resulting in PUSCH repetitions of transmission sequence  612 . The PUSCH repetitions of transmission sequence  612  may then be transmitted to the TRP. 
     If the PUCCH repetitions  604  and the PUSCH repetitions  608  are associated with different TRPs, e.g., if TRP PUCCH  is different than TRP PUSCH , the UE  104  may determine the transmission based on a priority of the associated TRP index, for example, a CORESET pool index. In some embodiments, the CORESET pool index with the lower value may be considered to have a relatively higher priority. 
     In some embodiments, if Pri(TRP PUCCH ) is greater than Pri(TRP PUSCH ), the UE  104  may choose one of two sub-options. In a first sub-option, the UE  104  may drop the PUSCH repetitions that collide with the PUCCH repetitions  604 , for example, PUSCH repetitions #1 and #2, and transmit the remaining repetitions. This is shown as transmission sequence  616  of  FIG.  6   . In a second sub-option, the UE  104  may drop all PUSCH repetitions resulting in transmission sequence  620  that only includes the PUCCH repetitions. 
     In some embodiments, if Pri(TRP PUSCH )) is greater than Pri(TRP PUCCH ), the UE  104  may drop one or more of the PUCCH repetitions  604 . The resulting transmission sequence  624  may then correspond to the PUSCH repetitions  608 . In some embodiments, only the PUCCH repetitions with overlapped symbols may be dropped. For example, if one or more PUCCH repetitions do not overlap with the PUSCH repetitions, those may be transmitted. In other embodiments, all the PUCCH repetitions may be dropped even if only some of the PUCCH repetitions overlap with PUSCH repetitions. 
       FIG.  7    illustrates a collision resolution procedure  700  that may be used for the second option of case 3 in accordance with some embodiments. Collision resolution procedure  700  may be based on principle 1. 
     Collision resolution procedure  700  includes PUCCH repetitions  704  that collide with first and second repetitions of PUSCH repetitions  708 . In this embodiment, the UE  104  may multiplex the UCI to the first actual PUSCH repetitions among the repetitions that meet the timeline constraint (defined in section 9.2.5 of TS 38.214, for example) with the same beam. The UE  104  may determine that: PUSCH repetition #1 is the first PUSCH repetition for the transmit beam X that satisfies the timeline constraints; and PUSCH repetition #3 is the first PUSCH repetition for the transmit beam Y that satisfies the timeline constraints. Therefore, the UE  104  may generate the sequence  712  in which the UCI is multiplexed to PUSCH repetition #1 and PUSCH repetition #3. 
     The collision resolution procedure  700  may be independent of the TRP indices associated with the PUSCH/PUCCH transmissions. Alternatively, the collision resolution procedure  700  may be used when the TRP indices are the same, for example, as an alternative to transmission sequence  612 . 
     In some embodiments, a third option for a collision procedure for case 3, which may also be based on principle 1, may be used. In this option, the UCI may be multiplexed to all the PUSCH repetitions. In various embodiments, this may be based on, or independent from, consideration of target TRPs associated with the PUCCH or PUSCH transmissions. 
     In some embodiments, different options may be used for PUCCH with repetitions within a slot or across slots. For example, option 1 may be used when PUCCH repetitions are within a slot, while option 2 may be used when PUCCH repetitions are across slots. Other options may be used in other embodiments. 
     Collision resolution procedures to address case 4—PUCCH with repetition colliding with another PUCCH with repetition—may be based on relative priorities of the PUCCHs. The priority-based collision-resolution procedure, which may be based on principles 1-3, may include the UE  104  dropping at least some of the PUCCH repetitions having lower priority. 
     In various embodiments, priority may be based on one or more of: UCI type, an associated TRP index (for example, a CORESET pool index); a number beams configured across all repetitions for the PUCCH transmission; a starting slot index; or a repetition type (for example, intra-slot repetition or inter-slot repetition). 
     With respect to UCI type, some embodiments may include, in order of decreasing priority, HARQ-ACK, SR, CSI with high-priority, and CSI with low priority. 
     With respect to associated TRP index, some embodiments may assign a higher priority to a lower index, which may be a TRP index or a CORESET pool index. 
     With respect to a number of beams, some embodiments may assign a higher priority to a PUCCH having repetitions on more beams. For example, if a first PUCCH has repetitions across three beams, and a second PUCCH has repetitions across to beams, the first PUCCH may have a higher priority than the second PUCCH. In other embodiments, the priorities may be reversed with the second PUCCH having the relatively higher priority. 
     With respect to the starting slot index, some embodiments may assign a higher priority to the PUCCH that has the earlier starting slot index. 
     With respect to the repetition type, some embodiments may assign a higher priority to the PUCCH having an intra-slot repetition. Other embodiments may reverse the priority and the PUCCH having inter-slot repetitions may be afforded the higher priority. 
     Various embodiments may include nested priorities based on the above PUCCH characteristics. A first example may include the following. The PUCCH priority is first determined by a number of beams to be used to transmit the PUCCH repetitions. If the number of beams of the same, the priority is determined by UCI type. If the UCI type is the same, the priority is determined by the starting slot index. A second example may include the following. The PUCCH priority is first determined by associated TRP indices. If the PUCCHs are associated with the same TRP index, the priority may be determined by UCI type. If the UCI type is the same, the priority may be determined by the starting slot index. Other embodiments may include other nested priority examples. 
     Embodiments addressing case 5—PUCCH with repetition colliding with PUSCH without repetition—may be addressed as follows. The UE  104  may determine whether to drop the PUSCH or the PUCCH based on option 1 of case 1. See, for example, the collision resolution procedure  200  of  FIG.  2   . 
     Embodiments addressing case 6—PUCCH with repetition colliding with an aperiodic SRS—may be addressed as follows. If priority for the PUCCH is configured to be 0, only the PUCCH repetitions and overlapped symbols may be dropped. This may be applied for PUCCH with repetitions within a slot or across slots. 
     For case 7, PUSCH with repetition colliding with an SRS, if the PUSCH is configured with a priority equal to 1, the UE  104  may not transmit the SRS and overlapped symbols. Otherwise, the collision may not be allowed in the SRS may be transmitted after the PUSCH. 
     In some embodiments an additional option may be considered to introduce a higher-layer signaling to determine the channel that should be dropped. This higher-layer signaling, which may be RRC signaling, may be used in any one of the cases 1-7. In various embodiments, a default collision resolution procedure may operate such as that described above in any one of cases 1-7. This default procedure may be overridden by the higher-layer signaling. 
     In some embodiments, scheduling restrictions may be introduced to avoid the specific collisions described above with respect to cases 1-7. 
       FIG.  8    may include an operation flow/algorithmic structure  800  in accordance with some embodiments. The operation flow/algorithmic structure  800  may be performed or implemented by a UE such as, for example, UE  104  or  1200 ; or components thereof, for example, baseband processor  1204 A. 
     The operation flow/algorithmic structure  800  may include, at  804 , identifying a collision between a first uplink channel transmission and a second uplink channel transmission. The first and second uplink channel transmissions may be PUSCH or PUCCH transmissions, with or without repetitions. If the physical uplink channel transmissions include repetitions, the repetitions may be in consecutive slots (for example, repetition type A) or in consecutive symbols within a slot or across slots (for example, repetition type B). 
     In some embodiments, the collision may be identified at a mapping function in physical layer processing of the UE. The collisions may occur based on the transmissions being at least partially overlapping in time or frequency. In various embodiments, the collisions may be similar to any of the collisions described above with respect to cases 1-7. Additional or alternative collision scenarios may be detected and addressed in various embodiments. 
     The operation flow/algorithmic structure  800  may further include, at  808 , determining target TRPs for the first and second physical uplink channel transmissions. In some embodiments, the target TRPs may be determined based on TRP indices (for example, CORESET pool indices) associated with each of the physical uplink channel transmissions. In some embodiments, the association between the TRP indices and the physical uplink channel transmissions may be based on the PDCCH scheduling or otherwise configuring the resources for the physical uplink channel transmissions. 
     The operation flow/algorithmic structure  800  may further include, at  812 , performing a collision resolution procedure based on the target TRPs. The collision resolution procedure may be similar to any of those described above. For example, in some embodiments the collision resolution procedure may include determining relative priority of the first and second physical uplink channel transmissions based on the target TRP associated with each. In some embodiments this may be done by prioritizing transmissions associated with lower TRP indices. Other embodiments may include other manners of prioritization. 
     In some embodiments, if the target TRPs are the same, the UCI from a PUCCH transmission may be multiplexed to one or more PUSCH repetitions for transmission. If the target TRPs are different, the transmission associated with the relatively higher priority TRP may be transmitted, and some or all of the transmission associated with the relatively lower priority TRP may be dropped. 
     The operation flow/algorithmic structure  800  may further include, at  816 , transmitting the first or second physical uplink channel transmissions. In some embodiments, only the higher priority physical uplink channel transmission may ultimately be transmitted. In other embodiments, portions of the lower-priority physical uplink channel transmission may also be transmitted. For example, non-overlapped repetitions of the lower-priority physical uplink channel transmission may be transmitted in some embodiments. In other embodiments, information from the lower-priority physical uplink channel transmission may be multiplexed with the higher-priority physical uplink channel transmission as described herein. 
       FIG.  9    may include an operation flow/algorithmic structure  900  in accordance with some embodiments. The operation flow/algorithmic structure  900  may be performed or implemented by a UE such as, for example, UE  104  or  1200 ; or components thereof, for example, baseband processor  1204 A. 
     The operation flow/algorithmic structure  900  may include, at  904 , detecting a collision between first PUCCH repetitions and second PUCCH repetitions. The collision detected at  904  may correspond to case 4 described herein. 
     The operation flow/algorithmic structure  900  may further include, at  908 , determining priority information associated with the first and second PUCCH repetitions. The priority information may include information related to parameters that configure the respective PUCCH repetitions for transmission. In some embodiments, these parameters may include information related to target TRP (for example, associated TRP indices), a number of beams on which the respective PUCCH repetitions are to be transmitted, a starting slot in which the respective PUCCH repetitions are to be transmitted, repetition types of the respective PUCCH repetitions, or types of UCI carried in the respective PUCCH repetitions. 
     The operation flow/algorithmic structure  900  may further include, at  912 , determining first PUCCH repetitions have a relatively higher priority. The relative priorities may be determined by referencing one or more of the parameters of the priority information. As described elsewhere, nested priorities may include a plurality of the parameters being referenced in a defined order. For example, if first parameters are equal among the respective PUCCH repetitions, relative priorities may be determined by referencing second parameters, and so on. 
     The operation flow/algorithmic structure  900  may further include, at  916 , transmitting the first PUCCH repetitions and dropping one or more of the second PUCCH repetitions. In some embodiments, only the repetitions of the second PUCCH that overlap/collide with the first PUCCH repetitions may be dropped. Alternatively, all the repetitions of the second PUCCH may be dropped regardless of whether they overlap/collide with the first PUCCH repetitions. 
       FIG.  10    may include an operation flow/algorithmic structure  1000  in accordance with some embodiments. In some embodiments, the operation flow/algorithmic structure  1000  may be performed or implemented by a UE, for example, UE  104  or  1200 ; or components thereof, for example, baseband processor  1204 A. 
     The operation flow/algorithmic structure  1000  may include, at  1004 , identifying a collision between a PUCCH transmission and a PUSCH transmission. The PUSCH transmission may include a plurality of PUSCH repetitions that are to be transmitted on at least two beams. 
     The operation flow/algorithmic structure  1000  may further include, at  1008 , multiplexing UCI from the PUCCH transmission to a PUSCH repetition on each of a plurality of beams. In some embodiments, the UCI may only be transmitted on one PUSCH repetition per beam. The particular PUSCH repetition may be selected based on timeline constraints. For example, the selected PUSCH repetition may be the earliest occurring PUSCH repetition that is capable of carrying the UCI. In various embodiments, this may be determined based on configuration information provided by a gNB or processing capability of the UE. In other embodiments, the UCI may be multiplexed to all PUSCH repetitions. 
     The operation flow/algorithmic structure  1000  may further include, at  1012 , transmitting the PUSCH repetitions. 
       FIG.  11    illustrates beamforming circuitry  1100  in accordance with some embodiments. The beamforming circuitry  1100  may include a first antenna panel, panel 1  1004 , and a second antenna panel, panel 2  1108 . Each antenna panel may include a number of antenna elements. Other embodiments may include other numbers of antenna panels. 
     Digital beamforming (BF) components  1128  may receive an input baseband (BB) signal from, for example, a baseband processor such as, for example, baseband processor  1204 A of  FIG.  12   . The digital BF components  1128  may rely on complex weights to pre-code the BB signal and provide a beamformed BB signal to parallel radio frequency (RF) chains  1120 / 1124 . 
     Each RF chain  1120 / 1124  may include a digital-to-analog converter to convert the BB signal into the analog domain; a mixer to mix the baseband signal to an RF signal; and a power amplifier to amplify the RF signal for transmission. 
     The RF signal may be provided to analog BF components  1112 / 1116 , which may apply additionally beamforming by providing phase shifts in the analog domain. The RF signals may then be provided to antenna panels  1104 / 1108  for transmission. 
     In some embodiments, instead of the hybrid beamforming shown here, the beamforming may be done solely in the digital domain or solely in the analog domain. 
     In various embodiments, control circuitry, which may reside in a baseband processor, may provide BF weights to the analog/digital BF components to provide a transmit beam at respective antenna panels. These BF weights may be determined by the control circuitry to provide the directional provisioning of the serving cells as described herein. In some embodiments, the BF components and antenna panels may operate together to provide a dynamic phased-array that is capable of directing the beams in the desired direction. 
       FIG.  12    illustrates a UE  1200  in accordance with some embodiments. The UE  1200  may be similar to and substantially interchangeable with UE  104  of  FIG.  1   . 
     The UE  1200  may be any mobile or non-mobile computing device, such as, for example, mobile phones, computers, tablets, industrial wireless sensors (for example, microphones, carbon dioxide sensors, pressure sensors, humidity sensors, thermometers, motion sensors, accelerometers, laser scanners, fluid level sensors, inventory sensors, electric voltage/current meters, actuators, etc.), video surveillance/monitoring devices (for example, cameras, video cameras, etc.), wearable devices (for example, a smart watch), relaxed-IoT devices. In some embodiments, the UE may be a RedCap UE or NR-Light UE. 
     The UE  1200  may include processors  1204 , RF interface circuitry  1208 , memory/storage  1212 , user interface  1216 , sensors  1220 , driver circuitry  1222 , power management integrated circuit (PMIC)  1224 , antenna structure  1226 , and battery  1228 . The components of the UE  1200  may be implemented as integrated circuits (ICs), portions thereof, discrete electronic devices, or other modules, logic, hardware, software, firmware, or a combination thereof. The block diagram of  FIG.  12    is intended to show a high-level view of some of the components of the UE  1200 . However, some of the components shown may be omitted, additional components may be present, and different arrangement of the components shown may occur in other implementations. 
     The components of the UE  1200  may be coupled with various other components over one or more interconnects  1232 , which may represent any type of interface, input/output, bus (local, system, or expansion), transmission line, trace, optical connection, etc. that allows various circuit components (on common or different chips or chipsets) to interact with one another. 
     The processors  1204  may include processor circuitry such as, for example, baseband processor circuitry (BB)  1204 A, central processor unit circuitry (CPU)  1204 B, and graphics processor unit circuitry (GPU)  1204 C. The processors  1204  may include any type of circuitry or processor circuitry that executes or otherwise operates computer-executable instructions, such as program code, software modules, or functional processes from memory/storage  1212  to cause the UE  1200  to perform operations as described herein. 
     In some embodiments, the baseband processor circuitry  1204 A may access a communication protocol stack  1236  in the memory/storage  1212  to communicate over a 3GPP compatible network. In general, the baseband processor circuitry  1204 A may access the communication protocol stack to: perform user plane functions at a PHY layer, MAC layer, RLC layer, PDCP layer, SDAP layer, and PDU layer; and perform control plane functions at a PHY layer, MAC layer, RLC layer, PDCP layer, RRC layer, and a non-access stratum layer. In some embodiments, the PHY layer operations may additionally/alternatively be performed by the components of the RF interface circuitry  1208 . 
     The baseband processor circuitry  1204 A may generate or process baseband signals or waveforms that carry information in 3GPP-compatible networks. In some embodiments, the waveforms for NR may be based cyclic prefix OFDM “CP-OFDM” in the uplink or downlink, and discrete Fourier transform spread OFDM “DFT-S-OFDM” in the uplink. 
     The memory/storage  1212  may include one or more non-transitory, computer-readable media that includes instructions (for example, communication protocol stack  1236 ) that may be executed by one or more of the processors  1204  to cause the UE  1200  to perform various operations described herein. The memory/storage  1212  include any type of volatile or non-volatile memory that may be distributed throughout the UE  1200 . In some embodiments, some of the memory/storage  1212  may be located on the processors  1204  themselves (for example, L1 and L2 cache), while other memory/storage  1212  is external to the processors  1204  but accessible thereto via a memory interface. The memory/storage  1212  may include any suitable volatile or non-volatile memory such as, but not limited to, dynamic random access memory (DRAM), static random access memory (SRAM), eraseable programmable read only memory (EPROM), electrically eraseable programmable read only memory (EEPROM), Flash memory, solid-state memory, or any other type of memory device technology. 
     The RF interface circuitry  1208  may include transceiver circuitry and radio frequency front module (RFEM) that allows the UE  1200  to communicate with other devices over a radio access network. The RF interface circuitry  1208  may include various elements arranged in transmit or receive paths. These elements may include, for example, switches, mixers, amplifiers, filters, synthesizer circuitry, control circuitry, etc. 
     In the receive path, the RFEM may receive a radiated signal from an air interface via antenna structure  1226  and proceed to filter and amplify (with a low-noise amplifier) the signal. The signal may be provided to a receiver of the transceiver that down-converts the RF signal into a baseband signal that is provided to the baseband processor of the processors  1204 . 
     In the transmit path, the transmitter of the transceiver up-converts the baseband signal received from the baseband processor and provides the RF signal to the RFEM. The RFEM may amplify the RF signal through a power amplifier prior to the signal being radiated across the air interface via the antenna  1226 . 
     In various embodiments, the RF interface circuitry  1208  may be configured to transmit/receive signals in a manner compatible with NR access technologies. 
     The antenna  1226  may include antenna elements to convert electrical signals into radio waves to travel through the air and to convert received radio waves into electrical signals. The antenna elements may be arranged into one or more antenna panels. The antenna  1226  may have antenna panels that are omnidirectional, directional, or a combination thereof to enable beamforming and multiple input, multiple output communications. The antenna  1226  may include microstrip antennas, printed antennas fabricated on the surface of one or more printed circuit boards, patch antennas, phased array antennas, etc. The antenna  1226  may have one or more panels designed for specific frequency bands including bands in FR1 or FR2. 
     The user interface circuitry  1216  includes various input/output (I/O) devices designed to enable user interaction with the UE  1200 . The user interface  1216  includes input device circuitry and output device circuitry. Input device circuitry includes any physical or virtual means for accepting an input including, inter alia, one or more physical or virtual buttons (for example, a reset button), a physical keyboard, keypad, mouse, touchpad, touchscreen, microphones, scanner, headset, or the like. The output device circuitry includes any physical or virtual means for showing information or otherwise conveying information, such as sensor readings, actuator position(s), or other like information. Output device circuitry may include any number or combinations of audio or visual display, including, inter alia, one or more simple visual outputs/indicators (for example, binary status indicators such as light emitting diodes “LEDs” and multi-character visual outputs, or more complex outputs such as display devices or touchscreens (for example, liquid crystal displays “LCDs,” LED displays, quantum dot displays, projectors, etc.), with the output of characters, graphics, multimedia objects, and the like being generated or produced from the operation of the UE  1100 . 
     The sensors  1220  may include devices, modules, or subsystems whose purpose is to detect events or changes in its environment and send the information (sensor data) about the detected events to some other device, module, subsystem, etc. Examples of such sensors include, inter alia, inertia measurement units comprising accelerometers, gyroscopes, or magnetometers; microelectromechanical systems or nanoelectromechanical systems comprising 3-axis accelerometers, 3-axis gyroscopes, or magnetometers; level sensors; flow sensors; temperature sensors (for example, thermistors); pressure sensors; barometric pressure sensors; gravimeters; altimeters; image capture devices (for example, cameras or lensless apertures); light detection and ranging sensors; proximity sensors (for example, infrared radiation detector and the like); depth sensors; ambient light sensors; ultrasonic transceivers; microphones or other like audio capture devices; etc. 
     The driver circuitry  1222  may include software and hardware elements that operate to control particular devices that are embedded in the UE  1200 , attached to the UE  1100 , or otherwise communicatively coupled with the UE  1200 . The driver circuitry  1222  may include individual drivers allowing other components to interact with or control various input/output (I/O) devices that may be present within, or connected to, the UE  1200 . For example, driver circuitry  1222  may include a display driver to control and allow access to a display device, a touchscreen driver to control and allow access to a touchscreen interface, sensor drivers to obtain sensor readings of sensor circuitry  1220  and control and allow access to sensor circuitry  1220 , drivers to obtain actuator positions of electro-mechanic components or control and allow access to the electro-mechanic components, a camera driver to control and allow access to an embedded image capture device, audio drivers to control and allow access to one or more audio devices. 
     The PMIC  1224  may manage power provided to various components of the UE  1200 . In particular, with respect to the processors  1204 , the PMIC  1224  may control power-source selection, voltage scaling, battery charging, or DC-to-DC conversion. 
     In some embodiments, the PMIC  1224  may control, or otherwise be part of, various power saving mechanisms of the UE  1200 . For example, if the platform UE is in an RRC_Connected state, where it is still connected to the RAN node as it expects to receive traffic shortly, then it may enter a state known as Discontinuous Reception Mode (DRX) after a period of inactivity. During this state, the UE  1200  may power down for brief intervals of time and thus save power. If there is no data traffic activity for an extended period of time, then the UE  1200  may transition off to an RRC_Idle state, where it disconnects from the network and does not perform operations such as channel quality feedback, handover, etc. The UE  1200  goes into a very low power state and it performs paging where again it periodically wakes up to listen to the network and then powers down again. The UE  1200  may not receive data in this state; in order to receive data, it must transition back to RRC_Connected state. An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable. 
     A battery  1228  may power the UE  1200 , although in some examples the UE  1200  may be mounted deployed in a fixed location, and may have a power supply coupled to an electrical grid. The battery  1228  may be a lithium ion battery, a metal-air battery, such as a zinc-air battery, an aluminum-air battery, a lithium-air battery, and the like. In some implementations, such as in vehicle-based applications, the battery  1228  may be a typical lead-acid automotive battery. 
     It is well understood that the use of personally identifiable information should follow privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining the privacy of users. In particular, personally identifiable information data should be managed and handled so as to minimize risks of unintentional or unauthorized access or use, and the nature of authorized use should be clearly indicated to users. 
     For one or more embodiments, at least one of the components set forth in one or more of the preceding figures may be configured to perform one or more operations, techniques, processes, or methods as set forth in the example section below. For example, the baseband circuitry as described above in connection with one or more of the preceding figures may be configured to operate in accordance with one or more of the examples set forth below. For another example, circuitry associated with a UE, base station, network element, etc. as described above in connection with one or more of the preceding figures may be configured to operate in accordance with one or more of the examples set forth below in the example section. 
     EXAMPLES
