FR1 and FR2 may be associated with potential bottleneck channels. For example, in FR1, a potential bottleneck channel may be a PUSCH for enhanced mobile broadband (eMBB). The PUSCH for eMBB may be associated with frequency division duplexing (FDD) or time division duplexing (TDD) with a certain slot configuration (e.g., DDDSU, DDDSUDDSUU, or DDDDDDDSUU, where "D" represents a downlink slot, "S" represents a special slot, and "U" represents an uplink slot). In FR1, another potential bottleneck channel may be a PUSCH for Voice over Internet Protocol (VoIP). The PUSCH for VoIP may be associated with FDD or TDD with a certain slot configuration (e.g., DDDSU, or DDDSUDDSUU). In FR2, a potential bottleneck channel may be a PUSCH for eMBB, which may be associated with a certain slot configuration (e.g., DDDSU or DDSU). In FR2, another potential bottleneck channel may be a PUSCH for VoIP with a certain slot configuration (e.g., DDDSU or DDSU).

For PUSCH repetition type A, a UE may repeat a transport block across consecutive slots applying a same symbol allocation in each slot. However, for PUSCH repetition type A, a number of PUSCH repetitions may be based at least in part on a quantity of available uplink/special slots, as counting PUSCH repetitions based at least in part on the consecutive slots may limit a number of actual PUSCH repetitions.

<FIG> is a diagram illustrating an example <NUM> of a PUSCH repetition type A counting, in accordance with the present disclosure.

As shown by reference number <NUM>, in a PUSCH repetition counting for TDD (unpaired spectrum), a plurality of downlink slots, uplink slots, and/or special slots may be provided based at least in part on a slot configuration. A first PUSCH repetition may be associated with a first slot (an uplink slot or a special slot) and have a count value of <NUM>, and a count value for each subsequent slot (e.g., uplink slot, downlink slot, or special slot) may be incremented by one.

In this example, the first PUSCH repetition associated with the first slot may correspond to the count value of <NUM>, and a second PUSCH repetition associated with a second slot may correspond to a count value of <NUM>, as the first slot and the second slot may be separated by non-uplink slots (e.g., downlink slots). Further, the first slot and the second slot may be associated with a same symbol allocation. For example, when symbols <NUM>-<NUM> are used in the first slot for the first PUSCH repetition, then symbols <NUM>-<NUM> may also be used in the second slot for the second PUSCH repetition.

As shown by reference number <NUM>, in a PUSCH repetition counting for FDD (paired spectrum), a plurality of PUSCH repetitions may occur based at least in part on a slot configuration. A first PUSCH repetition may be associated with a first slot and have a count value of <NUM>, and a count value for each subsequent slot may be incremented by one.

As shown by reference number <NUM>, in a PUSCH repetition counting for TDD (paired spectrum), a plurality of PUSCH repetitions may occur based at least in part on a slot configuration. A first PUSCH repetition may be associated with a first slot and have a count value of <NUM>. In this example, the count value may not increment by one for each consecutive slot, irrespective of whether a next slot is an uplink slot, a downlink slot, or a special slot. Rather, the count value may only be incremented for a subsequent uplink/special slot.

In this example, the first PUSCH repetition associated with the first slot may correspond to the count value of <NUM>, and a second PUSCH repetition associated with a second slot may correspond to a count value of <NUM>, even though the first slot and the second slot may be separated by non-uplink slots (e.g., downlink slots). Thus, in this example, a quantity of PUSCH repetitions may be counted on a basis of available uplink/special slots, and the quantity of PUSCH repetitions may not be counted on a basis of consecutive slots, which may limit a number of actual PUSCH repetitions.

<FIG> is a diagram illustrating an example <NUM> of a DAPS-based handover, in accordance with the present disclosure. The DAPS-based handover may involve a UE, a source MCG (or source base station), a target MCG (or target base station), and a user plane function.

The DAPS-based handover may reduce a handover interruption time by enabling the UE to simultaneously connect to both the source MCG and the target MCG during the DAPS-based handover. The DAPS-based handover may be applicable to an intra-frequency handover, an intra-band inter-frequency handover, and/or an inter-band inter-frequency handover.

As shown in <FIG>, in a first action, a UE may perform radio resource management (RRM) reference signal measurements, where the RRM reference signal may be a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS). In a second action, an event trigger may occur at the UE, and in a third action, the UE may transmit a measurement report to the source MCG. The measurement report may indicate the RRM reference signal measurements. In a fourth action, the source MCG may perform a DAPS-based handover decision based at least in part on the measurement report. In a fifth action, the source MCG may prepare the target MCG for the DAPS-based handover.

In a sixth action, the source MCG may transmit a radio resource control (RRC) reconfiguration message to the UE. The RRC reconfiguration message may indicate a handover command. In a seventh action, the UE may connect to the target MCG, and in an eighth action, the UE may transmit an RRC reconfiguration complete message to the target MCG. In a ninth action, the target MCG may perform a source MCG connection release decision, and in a tenth action, the source MCG and the target MCG may communicate a handover connection setup complete indication. In an eleventh action, the target MCG may transmit, to the UE, an instruction to release the source MCG, and in a twelfth action, the UE may release the source MCG based at least in part on the indication received from the target MCG. In a thirteenth action, the UE may transmit an RRC reconfiguration complete message to the target MCG. In a fourteenth action, UE context information may be released with the source MCG. In a fifteenth action, the UE may communicate data on the target MCG.

In this example of the DAPS-based handover, the UE may be connected to both the source MCG and the target MCG during the handover of the UE from the source MCG to the target MCG. For example, between action seven and action eleven, the UE may continue data transmissions and receptions on the source MCG, even though the UE may also be connected to the target MCG.

For a DAPS-based handover that is not intra-frequency, a UE may transmit on a target cell (e.g., a target cell associated with a target MCG), and the UE may cancel a transmission to a source cell (e.g., a source cell associated with a source MCG). In other words, the UE may transmit only on the target cell and may cancel the transmission to the source cell. The UE may transmit on the target cell and cancel the transmission to the source cell based at least in part on UE transmissions on the target cell and the source cell being in overlapping time resources, the UE not indicating a capability for power sharing between the source MCG and the target MCG in the DAPS-based handover, and the UE indicates a support of uplink transmission cancellations associated with the DAPS-based handover.

For a DAPS-based handover that is intra-frequency, the UE may transmit on the target cell and cancel the transmission to the source cell based at least in part on UE transmissions on the target cell and the source cell being in overlapping time resources.

<FIG> is a diagram illustrating an example <NUM> of an uplink cancellation in a DAPS-based handover, in accordance with the present disclosure.

As shown in <FIG>, a UE may be connected to a source MCG and a target MCG during the DAPS-based handover. The UE may communicate with the source MCG based at least in part on a first slot configuration, and the UE may communicate with the target MCG based at least in part on a second slot configuration. In this example, the first slot configuration may be associated with a first slot that corresponds to an uplink transmission, a second slot that corresponds to an uplink transmission, a third slot that corresponds to a non-uplink transmission (e.g., a downlink transmission), and a fourth slot that corresponds to an uplink transmission. The second slot configuration may be associated with a first slot that corresponds to a non-uplink transmission, a second slot that corresponds to an uplink transmission, a third slot that corresponds to an uplink transmission, and a fourth slot that corresponds to a non-uplink transmission. In this example, since the second transmission associated with both the first slot configuration and the second slot configuration are uplink transmissions, the UE may cancel the second slot with the uplink transmission with respect to the source MCG. In other words, during the second slot associated with the first slot configuration and the second slot configuration, the UE may perform the uplink transmission to the target MCG and may cancel the uplink transmission to the source MCG.

A UE may be handed over from a source MCG to a target MCG based at least in part on a DAPS-based handover. During the DAPS-based handover, the UE may communicate with both a source base station associated with the source MCG and a target base station associated with the target MCG. Regardless of whether the DAPS-based handover is an intra-frequency DAPS-based handover, the UE may perform a transmission on the target MCG and may cancel a transmission on the source MCG based at least in part on the transmission on the source MCG overlapping in time with the transmission on the target MCG. However, a UE behavior may not be defined for a situation in which a PUSCH transmission with repetition on the source MCG is canceled based at least in part on an uplink transmission on the target MCG when DAPS-based handover is enabled for the UE.

In various aspects of techniques and apparatuses described herein, a UE may transmit, to a source base station associated with a source MCG, a PUSCH repetition in each of one or more slots of the source MCG during a DAPS-based handover of the UE from the source MCG to a target MCG. The UE may perform, to a target base station associated with the target MCG, an uplink transmission in one or more slots to the target MCG during the DAPS-based handover. In some aspects, the UE may cancel PUSCH repetitions associated with the source MCG that overlap in time with the uplink transmission to MCG. In some aspects, the UE may count the PUSCH repetitions based at least in part on slots of the source MCG associated with canceled PUSCH repetitions. In some aspects, the UE may count the PUSCH repetitions based at least in part on counting the slots of the source MCG associated with the canceled PUSCH repetitions. In some aspects, the UE may count the PUSCH repetitions based at least in part on not counting the slots of the source MCG associated with the canceled PUSCH repetitions.

<FIG> is a diagram illustrating an example <NUM> of PUSCH repetitions during handover, in accordance with the present disclosure. As shown in <FIG>, example <NUM> includes communication between a UE (e.g., UE <NUM>), a source base station UE (e.g., base station 110a), and a target base station (e.g., base station 110b). In some aspects, the UE, the source base station, and the target base station may be included in a wireless network such as wireless network <NUM>.

As shown by reference number <NUM>, the UE may transmit, to the source base station associated with a source MCG, a PUSCH repetition in each of one or more slots of the source MCG. The one or more slots may be uplink slots and/or special slots. The UE may transmit PUSCH repetitions in the one or more slots of the source MCG during a DAPS-based handover of the UE from the source MCG to a target MCG. In some aspects, the PUSCH repetitions may be associated with a PUSCH repetition Type A, in which a same symbol allocation is applied in each of the one or more slots of the source MCG.

In some aspects, the UE may receive, from the source base station, a configuration associated with a quantity of PUSCH repetitions. The UE may transmit, to the source base station, the PUSCH repetitions in the one or more slots of the source MCG based at least in part on the configuration.

In some aspects, the DAPS-based handover may be associated with an FDD-to-FDD handover. In some aspects, the DAPS-based handover may be associated with a TDD-to-TDD handover. In some aspects, the DAPS-based handover may be associated with a TDD-to-FDD handover. In some aspects, the DAPS-based handover may be associated with an FDD-to-TDD handover. Further, FDD may be associated with a paired spectrum and TDD may be associated with an unpaired spectrum.

As shown by reference number <NUM>, the UE may perform, to the target base station associated with the target MCG, an uplink transmission in one or more slots to the target MCG during the DAPS-based handover. The uplink transmission may be a physical uplink control channel (PUCCH) transmission, a PUSCH transmission, a sounding reference signal (SRS), a physical random access channel (PRACH) transmission, or a message <NUM> (Msg3) PUSCH transmission.

In some aspects, the UE may cancel PUSCH repetitions associated with the source MCG that overlap in time with the uplink transmission to MCG, where the one or more slots of the target MCG may be associated with the uplink transmission from the UE. In some aspects, the UE may cancel the PUSCH repetitions associated with the source MCG based at least in part on a lack of UE capability for power sharing between the source MCG and the target MCG during the DAPS-based handover. In some aspects, the UE may cancel the PUSCH repetitions associated with the source MCG based at least in part on a UE capability of canceling uplink transmissions during the DAPS-based handover.

In some aspects, the UE may count the PUSCH repetitions based at least in part on slots of the source MCG associated with canceled PUSCH repetitions. In one example, the UE may count the PUSCH repetitions based at least in part on counting the slots of the source MCG associated with the canceled PUSCH repetitions. In another example, the UE may count the PUSCH repetitions based at least in part on not counting the slots of the source MCG associated with the canceled PUSCH repetitions.

In some aspects, the PUSCH repetitions associated with the source MCG may fully overlap in time with the uplink transmission to MCG. In some aspects, the PUSCH repetitions associated with the source MCG may partially overlap in time with the uplink transmission to MCG.

In some aspects, when the UE may transmit a PUSCH repetition over a quantity of <MAT> slots available for PUSCH repetition transmissions in the source MCG, and the UE does not transmit a PUSCH repetition in a slot included in the quantity of <MAT> slots due to the slot overlapping in time with an uplink transmission to the target MCG, the UE may or may not count the slot included in the quantity of <MAT> slots. The slot in the quantity of <MAT> slots may be the slot associated with a canceled PUSCH repetition due to the slot overlapping in time with the uplink transmission to the target MCG. In this example, <MAT> may represent a slot (e.g., an uplink slot or a special slot) associated with a PUSCH repetition. The uplink transmission to the target MCG may be associated with a PUCCH, a PUSCH, an SRS, a PRACH, or a Msg3 PUSCH.

<FIG> is a diagram illustrating an example <NUM> of PUSCH repetitions during handover, in accordance with the present disclosure.

As shown in <FIG>, a plurality of slots may be configured for PUSCH repetition transmissions to a source MCG, and a plurality of slots may be configured for uplink transmissions (e.g., PUCCH transmissions, PUSCH transmissions, SRS transmissions, PRACH transmissions, and/or Msg3 PUSCH transmissions) to a target MCG. A UE may perform PUSCH repetition transmissions to the source MCG on one or more slots associated with the source MCG, and the UE may perform uplink transmissions to the target MCG on one or more slots associated with the target MCG. However, for slots associated with the source MCG that overlap in time with uplink transmissions in slots associated with the target MCG, the UE may cancel PUSCH repetition transmissions in those slots associated with the source MCG. In other words, the UE may cancel the PUSCH repetition transmissions in those slots and instead may perform the uplink transmissions to the target MCG.

A slot format configuration (e.g., a configuration of uplink slots, downlink slots, and special slots) may be defined for the source MCG and a slot format configuration may be defined for the target MCG. In an FDD-to-FDD handover, in a first counting scheme in which the UE counts slot(s) of the source MCG that are associated with canceled PUSCH repetition transmissions due to uplink transmissions to the target MCG that overlap in time resources, the UE may associate a first slot with a first PUSCH repetition transmission with a count value of <NUM>, and each subsequent slot may be associated with a count value that is incremented by one, irrespective of whether a subsequent slot is associated with a canceled PUSCH repetition transmission. In a second counting scheme in which the UE does not count slot(s) of the source MCG that are associated with canceled PUSCH repetition transmissions due to uplink transmissions to the target MCG that overlap in time resources, the UE may associate a first slot with a first PUSCH repetition transmission with a count value of <NUM>, and each subsequent slot that is associated with a PUSCH repetition transmission (e.g., not a canceled PUSCH repetition transmission) may be associated with a count value that is incremented by one.

As an example, in the second counting scheme, slots <NUM> and <NUM> may not be counted since the PUSCH repetition transmission to the source MCG is canceled based at least in part on the uplink transmission to the target MCG.

As shown in <FIG>, a slot format configuration (e.g., a configuration of uplink slots, downlink slots, and special slots) may be defined for the source MCG and a slot format configuration may be defined for the target MCG. In a TDD-to-TDD handover, in a first counting scheme in which the UE counts slot(s) of the source MCG that are associated with canceled PUSCH repetition transmissions due to uplink transmissions to the target MCG that overlap in time resources, the UE may associate a first slot with a first PUSCH repetition transmission with a count value of <NUM>, and each subsequent slot may be associated with a count value that is incremented by one, irrespective of whether a subsequent slot is associated with a canceled PUSCH repetition transmission. In a second counting scheme in which the UE does not count slot(s) of the source MCG that are associated with canceled PUSCH repetition transmissions due to uplink transmissions to the target MCG that overlap in time resources, the UE may associate a first slot with a first PUSCH repetition transmission with a count value of <NUM>, and each subsequent slot that is associated with a PUSCH repetition transmission (e.g., not a canceled PUSCH repetition transmission) may be associated with a count value that is incremented by one.

<FIG> is a diagram illustrating an example process <NUM> performed, for example, by a UE, in accordance with the present disclosure. Example process <NUM> is an example where the UE (e.g., UE <NUM>) performs operations associated with PUSCH repetitions during handover.

As shown in <FIG>, in some aspects, process <NUM> includes transmitting, to a source base station associated with a source MCG, a PUSCH repetition in each of one or more slots of the source MCG during a DAPS-based handover of the UE from the source MCG to a target MCG (block <NUM>). For example, the UE (e.g., using transmission component <NUM>, depicted in <FIG>) transmits, to a source base station associated with a source MCG, a PUSCH repetition in each of one or more slots of the source MCG during a DAPS-based handover of the UE from the source MCG to a target MCG, as described above.

As further shown in <FIG>, in some aspects, process <NUM> includes performing, to a target base station associated with the target MCG, an uplink transmission in one or more slots to the target MCG during the DAPS-based handover, wherein PUSCH repetitions associated with the source MCG that overlap in time with the uplink transmission to MCG are canceled and a counting of the PUSCH repetitions is based at least in part on slots of the source MCG associated with canceled PUSCH repetitions (block <NUM>). For example, the UE (e.g., using transmission component <NUM>, depicted in <FIG>) performs, to a target base station associated with the target MCG, an uplink transmission in one or more slots to the target MCG during the DAPS-based handover, wherein PUSCH repetitions associated with the source MCG that overlap in time with the uplink transmission to MCG are canceled and a counting of the PUSCH repetitions is based at least in part on slots of the source MCG associated with canceled PUSCH repetitions, as described above.

In a first aspect, the counting of the PUSCH repetitions includes counting the slots of the source MCG associated with the canceled PUSCH repetitions.

In a second aspect, alone or in combination with the first aspect, the counting of the PUSCH repetitions includes not counting the slots of the source MCG associated with the canceled PUSCH repetitions.

In a third aspect, alone or in combination with one or more of the first and second aspects, the PUSCH repetitions associated with the source MCG fully overlap in time with the uplink transmission to MCG.

In a fourth aspect, alone or in combination with one or more of the first through third aspects, the PUSCH repetitions associated with the source MCG partially overlap in time with the uplink transmission to MCG.
