Abstract: A base station performs joint channel estimation for a set of physical uplink control channels (PUCCHs), where one or more PUCCHs of the set of PUCCHs comprises a corresponding DMRS from a user equipment (UE). The UE receives an indication to transmit the set of PUCCHs, one or more PUCCHs of the set of PUCCHs comprising a DMRS from the base station. The base station transmits, and the UE receives, spatial filter or power control information elements for each PUCCH of the set of PUCCHs. The UE transmits the PUCCHs comprising corresponding DMRS based on a same spatial filter with a same power control parameters, spatial filter or power control information element for a first PUCCH of the set of PUCCHs indicating the same spatial filter or same power control parameter, the set of PUCCHs having phase continuity.

Abstract: A base station performs joint channel estimation for a set of physical uplink shared channels (PUSCHs) with bundled DMRS from a user equipment (UE). The UE receives an indication to transmit the set of PUSCHs, each PUSCH of the set of PUSCHs comprising a corresponding DMRS from the base station. The base station transmits, and the UE receives, a sounding reference signal resource indicator for each PUSCH of the set of PUSCHs. The UE transmits the PUSCHs based on a same sounding reference single resource, the SRI for a first PUSCH of the set of PUSCHs indicating the same SRS resource.

Abstract: Wireless communications systems and methods related to sidelink transmissions from a relay user equipment (UE) to a remote UE are provided. For example, a first UE receives, from a second UE, a configuration indicating a set of resource regions spaced apart from each other in time. The first UE monitors, in one or more of the resource regions, for sidelink control information. The first UE receives, from the second UE based on the monitoring, the sidelink control information in a first resource region of the set of the resource regions. The first UE receives, from the second UE based on the sidelink control information, sidelink data.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a transmitting device may transmit a reference signal indicating a first service type supported by the transmitting device and a receiving device may receive the reference and determine whether to measure a signal strength associated with the reference signal based on determining whether the first service type supported by the transmitting device and a second service type supported by the receiving device are a same service type. For example, the receiving device may measure the reference signal if the first service type indicated by the reference signal and the second service type supported by the receiving device are the same service type. Alternatively, the receiving device may refrain from measuring the reference signal if the first service type indicated by the reference signal and the second service type supported by the receiving device are different service types.

Abstract: Wireless communication techniques that include techniques for setting power of peak reduction tones are discussed. A UE may receive a signal. The UE may set power associated with at least one peak reduction tone in accordance with a path loss between the UE and a base station. The path loss may be in accordance with the received signal. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for beam management for make-before-break (MBB) handover. A method that may be performed by a user equipment (UE) includes establishing a first cell connection with a first base station (BS) while maintaining an existing second cell connection with a second BS, and determining that a first transmission time of a first signal transmitted by the first BS is less than a threshold time duration from a second transmission time of a second signal transmitted by the second BS. In some examples, the first signal is associated with one or more first communication metrics and the second signal is associated with one or more second communication metrics, wherein each of the one or more first communication metrics and the one or more second communication metrics comprise one or more quality of service (QoS) metrics.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method includes selecting between a first frequency range and a second frequency range to transmit a physical channel, the second frequency range being higher than the first frequency range, and jointly encoding at least two fields of the physical channel based at least in part on the selected frequency range. In some cases, the method includes selecting between a first frequency range and a second frequency range to transmit a physical channel. In some cases, the second frequency range is higher than the first frequency range. The method may further include adjusting a quantity of bits associated with a field of the physical channel based at least in part on the selected frequency range.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with comprising a set of monitoring occasions for a reference signal. While the UE is in an inactive mode or an idle mode, a configuration for the set of monitoring occasions may be updated. The UE may be transmitted an indication of the updated set of monitoring occasions while the UE is in the inactive mode or the idle mode. The indication for the updated set of monitoring occasions may be sent via paging or system information messages.

In some aspects, a transmitter may identify a set of resource elements on which to transmit a reference signal based at least in part on a numerology being used by the transmitter and at least one of a maximum system numerology or a minimum system numerology; and transmit the reference signal on the identified set of resource elements. In some aspects, a receiver may identify a set of resource elements from which to obtain a reference signal based at least in part on a numerology being used by the receiver and at least one of a maximum system numerology or a minimum system numerology; and obtain the reference signal from the identified set of resource elements.
