Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station and while operating in a dual connectivity mode, an uplink grant in a first subframe of a set of subframes. The uplink grant may schedule transmission of uplink data. The UE may determine a second subframe of the set of subframes to transmit the uplink data and a third subframe of the set of subframes to monitor for feedback associated with transmission of the uplink data. The second subframe and the third subframe may be determined based on combinations of a primary cell time division duplex (TDD) uplink-downlink (UL-DL) configuration and a DL-reference UL-DL configuration. each of the combinations may have at least three uplink transmission subframes or three downlink monitoring subframes within a ten-subframe cycle. The UE may thus perform wireless communications in accordance with the transmission timelines.

Abstract: Certain aspects of the present disclosure provide techniques for dynamically controlling uplink transmit power for multi-connectivity transmissions. An example method generally includes communicating with a first cell group and a second cell group in a multi-connectivity mode, determining whether to multiplex uplink control information (UCI) of a first transmission with a payload of a second transmission on a physical uplink shared channel (PUSCH) based at least in part on a reserved transmission power level associated with the first cell group, and transmitting, to the first cell group, at least one of the UCI or the payload based on the determination.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications network may set priorities for cell groups in dual connectivity. A higher priority cell group may reserve slots and indicate the reserved slots to the lower priority cell group, for example by a backhaul connection. The high priority cell group may also indicate additional, non-reserved slots, which the lower priority cell group may reserve or use for scheduling. One of the cell groups may transmit a slot format indication (SFI) to a user equipment (UE) in the dual connectivity to indicate the slot reservations. In some cases, a hybrid automatic repeat request (HARQ) timing parameter may be based on a number of reserved slots. In some cases, power control may be varied based on whether the UE is capable of simultaneous uplink and downlink transmission.

Abstract: Various aspects of the disclosure relate to reporting power headroom of an apparatus such as a user equipment (UE). For an apparatus that uses beamforming, the power headroom associated with the beam the apparatus is using for wireless communication (e.g., with a base station) may be lower than the power headroom associated with another beam that the apparatus could use for the wireless communication. The disclosure relates in some aspects to using one beam for wireless communication and using the power headroom for another beam for a power headroom report. In this way, the apparatus may always report its full transmit power capability.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive a first set of grants for performing uplink transmissions between the UE and a first group of cells associated with a first radio access technology (RAT) and a second set of grants for performing uplink communication between the UE and a second group of cells associated with a second RAT. The UE may determine that a combined transmit power exceeds a total power limit or that there may be a potential of the combined power exceeding the total power limit. The UE may further perform the uplink communication with the first group of cells using the first RAT and the second group of cells using the second RAT.

Abstract: Methods, systems, and devices for wireless communications are described. A non-terrestrial network (NTN) device (e.g., a satellite, base station) may transmit, to a user equipment (UE), at a first frequency a synchronization signal block (SSB) that indicates a second frequency of a control resource set (CORESET) relative to the SSB, where the second frequency is based on one or more of: a CORESET bandwidth, a combination of a first parameter associated with a first portion of the SSB and a second parameter associated with a second portion of the SSB, or both. The UE may monitor the CORESET at the indicated second frequency for a downlink control channel transmission. The NTN device may transmit, to the UE, a downlink control channel transmission over the CORESET. The NTN device may transmit, to the UE, system information based on the downlink control channel transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a network may establish communications over a directional beam. The UE may receive, from the network, a configuration of one or more channel sounding messages for one or more directional beams, where each directional beam of the one or more directional beams is associated with a set of narrowband carriers, and each of the one or more channel sounding messages being configured for transmission on a narrowband carrier of the set of narrowband carriers. The UE may determine a trigger for transmitting the one or more channel sounding messaged based at least in part on the configuration and transmit, to the network, the one or more channel sounding messages on respective narrowband carriers in accordance with the trigger and the configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) receives one or more downlink signals using a first beam associated with a first set of frequency resources, switches from the first beam to a second beam associated with a second set of frequency resources, selects a set of frequency resources for transmitting feedback information associated with the one or more downlink signals, and transmits the feedback information to the base station using the selected set of frequency resources. In some examples, the UE transmits one or more uplink signals to a base station using a first beam associated with a first set of frequency resources, switches from the first beam to a second beam associated with a second set of frequency resources, and determines whether to send a retransmission of the one or more uplink signals based at least in part on switching.

Abstract: Aspects described herein relate to configuring a media access control (MAC)-control element (CE) to update a sounding reference signal (SRS) beam within a wireless communication system. Other aspects described herein relate to configuring default beam information for determining a beam for data channel communications within the wireless communication system. A user equipment (UE) or other device can determine to use the default beam information for configuring the beam for a data channel communication and for performing power control using, e.g., physical uplink shared channel (PUSCH) parameters. In addition, in some examples, the device can transmit the data channel communication using a beam configured based on the default beam information.
