Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select an uplink transmission power sharing configuration to use for transmission of one or more uplink messages. The uplink transmission power sharing configuration may be based on a first uplink transmission power capability of a first radio frequency (RF) chain of the UE and on a second uplink transmission power capability of a second RF chain of the UE. The UE may transmit the one or more uplink messages to a network entity in accordance with the uplink transmission power sharing configuration. Specifically, the UE may transmit the one or more uplink messages via the first RF chain using a first transmission power, and may transmit the one or more uplink messages via the second RF chain using a second transmission power that is different from the first transmission power.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may receive a feedback configuration for providing feedback for downlink communications from a base station. Based on the feedback configuration, the UE may determine whether one or more feedback processes has a multicast-only configuration for multicast data communications, or a multicast-or-unicast configuration for either multicast data communications or unicast data communications. The UE may decode one or more transmissions associated with the one or more feedback processes based on the multicast-only or multicast-or-unicast configuration, and may determine a feedback codebook based on the multicast-only or multicast-or-unicast configuration of the one or more feedback processes. The UE may monitor for retransmissions of one or more multicast data communications based on the feedback process configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a scheduling configuration for scheduling communications on a first component carrier. The scheduling configuration may indicate at least a first downlink control channel candidate on a second component carrier that is linked for control message repetition to a second downlink control channel candidate on one of the first component carrier or a third component carrier. The UE may then receive, from the base station and based on the scheduling configuration, at least one repetition of a control message in the first downlink control channel candidate or the second downlink control channel candidate, the control message scheduling a communication between the base station and the UE over the first component carrier. The UE may then transmit or receive the communication with the base station over the first component carrier.

Abstract: This disclosure provides systems, methods and apparatus for a signaling mechanism associated with activating a secondary cell (SCell) for uplink control information (UCI), including under circumstances in which the SCell is deactivated and belongs to a timing advance group (TAG) lacking a valid timing advance (TA) value. In one aspect, a user equipment (UE) and one or more components of a network entity may employ a signaling mechanism for establishing an SCell as a PUCCH-SCell in scenarios in which the PUCCH-SCell belongs to a secondary TAG (sTAG) lacking a valid TA value. The signaling mechanism may include signaling to directly provide the network entity with beam measurement information associated with one or more SCells of the sTAG or may include singling that the network entity may use to derive the beam measurement information associated with the one or more SCells of the sTAG.

Abstract: Aspects include systems, methods, devices, and non-transitory processor readable storage mediums for managing a broadcast signal of an apparatus for wireless communication. Various aspects may enable an apparatus to send a message using either omnidirectional transmissions or beamformed transmission based on whether the altitude of the apparatus meets an altitude threshold. In some implementations and aspects, the processor of the apparatus may determine a type of the message and may select the altitude threshold based on the determined message type. In some implementations and aspects, the processor of the apparatus may send the message using beamformed transmissions in response to determining that the message is intended for reception by a certain type of second apparatus.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may apply a scaling factor to a transport block of a first size, where the scaling factor may increase the transport block from the first size to a second size. The base station may interleave a set of parts of the transport block of the second size across a set of transmission time intervals (TTIs) in accordance with a transport block allocation pattern, where the set of TTIs may be contiguous or separated from each other by one or more intervening intervals. The base station may transmit, to a user equipment, an indication of the transport block allocation pattern applied to the transport block of the second size, and may transmit the set of parts of the transport block of the second size across the set of TTIs in accordance with the transport block allocation pattern.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that indicates whether a common search space (CSS) is associated with a first type of physical downlink control channel (PDCCH) or a second type of PDCCH. The first type of PDCCH may correspond to a cell-broadcast PDCCH and the second type of PDCCH may correspond to a UE-specific PDCCH. The CSS may be for downlink control information (DCI) with a cyclic redundancy check scrambled by a group radio network temporary identifier (G-RNTI) that schedules a multicast and broadcast service (MBS). The UE may receive, from the base station, the first type of PDCCH or the second type of PDCCH. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques may provide for handling of priority indications in scenarios where simultaneous physical uplink control channel (PUCCH)-physical uplink shared channel (PUSCH) is supported. For example, wireless communications systems may configure (e.g., via radio resource control (RRC) signaling) simultaneous PUCCH-PUSCH across two or more carriers, where piggybacking of feedback information on uplink shared channel transmission may be disabled. Further, a grant (e.g., downlink control information (DCI) scheduling a PUSCH transmission) may include a priority index field to indicate a priority associated with a transmission or resources scheduled by the grant. The described techniques may provide for efficient handling of priority indications associated with scheduled transmissions that overlap when simultaneous PUCCH-PUSCH is supported (e.g., techniques are provided for performing or dropping scheduled transmissions that overlap when simultaneous PUCCH-PUSCH is enabled based on any priority indications associated with the overlapping scheduled transmissions).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a set of resources for one or more synchronization signal blocks (SSBs) associated with one or more pseudo-random sequences. The one or more pseudo-random sequences and the set of resources may be indicated by an output of a pseudo-random function (PRF) that is based on a timing parameter, a cell identifier, and a key. In some examples, the UE may monitor a set of resources within a control resource set for a downlink control channel, where the set of resources for the downlink control channel is based on an output of the PRF. The UE communicate with a network entity via a cell associated with the cell identifier based on the monitoring.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether an uplink communication for a first radio access technology (RAT) has been dynamically scheduled or semi-statically configured, wherein the UE is in a dual connectivity mode using the first RAT and a second RAT. The UE may identify an uplink subframe for transmission of the uplink communication based at least in part on whether the uplink communication has been dynamically scheduled or semi-statically configured, and based at least in part on a downlink-reference uplink-downlink configuration. The UE may transmit the uplink communication in the identified uplink subframe. Numerous other aspects are provided.
