Abstract: Methods, systems, and devices for wireless communications are described. Generally, a network entity may configure a user equipment (UE) with transmission time interval (TTI) format information, and the UE may determine time domain windows for joint channel estimation based thereon. The network entity may also configure the UE with an association between one or more demodulation reference signal (DMRS) ports and one or more phase-tracking reference signal (PTRS) ports. The UE may maintain phase continuity across physical uplink channel transmissions within a time domain window in which a PTRS is scheduled when DMRS and PTRS are transmitted via the associated DMRS and PTRS ports (e.g., when the PTRS-DMRS association is identical across the time domain window). In some cases, the UE may not maintain phase continuity across multiple physical uplink channel transmissions occurring within a time domain window when a PTRS is also scheduled within the time domain window.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a capability of the UE is sufficient for a make-before-break (MBB) handover from a source set of cells to a target set of cells, wherein the source set of cells is provided by a first set of transmit/receive points (TRPs) and the target set of cells is provided by a second set of TRPs; and selectively perform the MBB handover using a first capability configuration for the MBB handover or a second capability configuration for the MBB handover based at least in part on whether the capability of the UE is sufficient for the MBB handover. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message identifying a frequency hop configuration that configures the UE to use frequency hopping when transmitting repetitions of an uplink control channel transmission. The UE, the base station, or both may determine, based on the UE being configured with the frequency hop configuration, a frequency hop for each repetition of the uplink control channel transmission. Each frequency hop may be determined based on a corresponding uplink control channel index for a respective repetition a frequency hop for each repetition of the uplink control channel transmission. The uplink control channel index may be an uplink transmission occasion index, or a repetition index. The UE may transmit the repetitions of the uplink control channel transmission using respective frequency hops in accordance with the determination and the frequency hop configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), that is configured for demodulation reference signal (DMRS) bundling, may receive a control message that schedules first and second sets of repetitions of an uplink transmission. The UE may determine a phase coherency configuration to be applied for DMRS transmissions corresponding to each set of repetitions. The phase coherency configuration may be determined based on a phase coherency capability of the UE, and the phase coherency configuration may specify that phase coherency is to be maintained for one or more of the first set of repetitions separate from one or more of the second set of repetitions. The UE may transmit the first set of repetitions with a first set of demodulation reference signals and the second set of repetitions with a second set of demodulation reference signals in accordance with the phase coherency configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit uplink transmissions according to a frequency hopping pattern. The UE may identify that a first set of uplink transmissions are to be transmitted to a base station by a first set of resources (e.g., a first set of slots, a first set of frequency resources) as indicated by the frequency hopping pattern. The UE may further identify, based on the frequency hopping pattern, that a second set of uplink transmissions are to be transmitted to the base station by a second set of resources (e.g., a second set of slots, a second set of frequency resources). The first set of slots and the second set of slots may each include more than one slot. Additionally, the first and second set of resources may be within a same bandwidth part or in different bandwidth parts.

Abstract: Methods, systems, and devices for wireless communications are described that provide for selection of different sets of transmission beams by a user equipment (UE) for establishing beamformed communications with a base station. Each transmission beam of a first set of transmission beams may have corresponding uplink random access channel (RACH) resources. A UE may monitor for transmission beams from a base station and select a first transmission beam of the first set for communications with the base station. As part of a connection establishment, the base station may provide configuration information that indicates a second set of transmission beams that includes each transmission beam of the first set of transmission beams and at least an additional transmission beam. In some cases, the additional transmission beam may be mapped to a first RACH resource that also corresponds to a first transmission beam of the first set of transmission beams.

Abstract: Methods, systems, and devices for wireless communications are described to switch between waveform configurations based on an indicated modulation coding scheme (MCS) such that waveform switching may be signaled implicitly. A base station may configure a user equipment (UE) with a hybrid MCS table including MCS indexes associated with a first waveform configuration and MCS indexes associated with a second waveform configuration. The base station may schedule resources for an uplink transmission for the UE and may indicate an MCS index associated with the uplink transmission, using index from the MCS table. The UE may select a waveform configuration for the uplink transmission based on the MCS index. For example, the UE may compare the MCS index with a threshold MCS index of the hybrid MCS table and determine a waveform configuration associated with the MCS index based on whether the MCS index falls above or below the threshold.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a downlink control information (DCI) message scheduling a first message and including an indication that the first message is scheduled for full-duplex operation with a second message. The indication may be a DCI field configured for indicating full-duplexing, or the DCI field may be an existing DCI field configured to also indicate full-duplexing. The UE may identify a set of parameters associated with the full-duplex operation of the first message based on receiving the DCI message that includes the indication, and the UE may communicate the first message using the set of parameters associated with the full-duplex operation and based on the indication included in the DCI message.

Abstract: Wireless communications systems and methods related to resource partitioning for sidelink are provided. A first user equipment (UE) transmits, to a second UE, a time-division duplexing (TDD) configuration indicating a first set of resources time-multiplexed with a second set of resources in a sidelink resource pool, wherein the first set of resources is associated with a first link, and wherein the second set of resources is associated with a second link different from the first link. The first UE receives from the second UE over the first link, a first communication signal in a resource of the first set of resources. The first UE transmits, to the second UE over the second link, a second communication signal using a resource of the second set of resources.
