Abstract: A UE may determine a number of antenna ports associated with a frequency band that includes one or more CCs. The determined number of antenna ports may be based on a plurality of UL Tx chains for the one or more CCs/frequency band. The UE may switch from a first UL Tx chain to a second UL Tx chain, at least one of which may be associated with the one or more CCs/frequency band. The number of antenna ports may correspond to a maximum number of antenna ports of an individual CC of the one or more CCs, or to a sum of antenna ports of the one or more CCs. For the latter, the number of antenna ports may be limited to an available number of UE antenna ports when the sum of antenna ports is greater than the available number of UE antenna ports.

Abstract: Aspects are provided which allow a UE to apply power-efficient UCI multiplexing rules accounting for situations in which CCs of overlapping PUCCH and PUSCH are in different carrier groups during inter-band CA to result in improved transmission performance. The UE transmits UCI in a PUCCH in a first CC in response to the PUCCH overlapping in time with a PUSCH in a second CC and the first CC being associated with a different carrier group than the second CC. Alternatively, the UE transmits UCI in the PUSCH in the second CC in response to the PUCCH overlapping in time with the PUSCH and the first CC being associated with a same carrier group as the second CC. Furthermore, the UE may apply a diversity scheme for UCI transmissions to achieve improved reliability of UCI feedback. The UE may also indicate which carrier includes UCI based on different DMRS configurations.

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).
