Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive from a network entity a message indicating one or more sets of parameters for a set of carriers supported by the UE, the one or more sets of parameters indicating communication parameters for communications via the set of carriers. The UE may monitor for a field of a control message based on the message. A field size of the field may be based on the sets of parameters, and a respective value for the field may indicate a respective set of parameters of the sets of parameters for one or more carriers of the set of carriers. Based on receiving a control message and decoding the associated field, the UE may communicate via at least one carrier of the set of carriers using the respective set of parameters for the at least one carrier.

Abstract: Methods, systems, and devices for wireless communication are described. A network entity may schedule uplink resource allocations across multiple cells by defining selection criteria for the uplink resource allocations in which to transmit a channel state information (CSI) report. For example, a user equipment (UE) may receive a control signal from the network entity, which may schedule the UE to transmit the CSI report in an uplink resource allocation on a component carrier in a carrier aggregation configuration. In some examples, the UE may transmit the CSI report by multiplexing the CSI report in uplink resource allocations on multiple component carriers. In some examples, the CSI report may be transmitted in an uplink resource allocation on a smallest component carrier index. Accordingly, the defined selection criteria may allow for more efficient procedures at the UE, which may result in increased efficiency and decreased overhead.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a control resource set (CORESET) associated with a first radio access technology (RAT). The UE may receive an indication of a pattern for puncturing a control signal associated with the first RAT around resources allocated for reference signals associated with a second RAT. The UE may communicate the control signal according to the pattern. In some examples, the CORESET may be associated with a transmission configuration indicator (TCI) state and the UE may receive a message scheduling a data signal based on the CORESET. The data signal may be associated with the first RAT. The UE may receive an indication of a pattern for rate-matching the data signal around the resources allocated for reference signals associated with the second RAT. The UE may communicate the data signal according to the pattern.

Abstract: Systems, methods, and devices for secondary cell activation using temporary reference signals are provided. In one aspect, a method of wireless communication performed by a user equipment (UE), includes receiving, from a base station (BS) via a first cell, an activation command to activate a second cell different from the first cell, and receiving, from the BS via the second cell during an activation period, a first reference signal different from a synchronization signal block (SSB). The method further includes performing a measurement of the first reference signal, and operating in the second cell based on the measurement. In some aspects, using reference signals different from SSBs may reduce the delay associated with activating the secondary cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may provide hybrid automatic repeat request (HARQ) feedback for multiple physical channels (e.g., multiple physical downlink shared channels (PDSCH)) scheduled via cross component carrier scheduling. A base station may transmit downlink control information (DCI) messages via physical downlink control channel (PDCCH), to the UE to schedule the multiple PDSCH over multiple component carriers. The UE may monitor for the multiple PDSCH over the multiple component carriers, respectively. The UE may identify resource allocations to use for HARQ feedback transmissions associated with the multiple PDSCH, based on the DCI messages received. The DCI may include a number of control fields that the UE may use to determine resource allocations to use for the HARQ feedback transmissions. The UE may thus improve coverage for wireless communications by supporting HARQ feedback for multiple PDSCH scheduled via cross component carrier.

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: Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes receiving first downlink (DL) control information (DCI) for scheduling resources in time in a system frame for transmission of one or more uplink (UL) data channels and hybrid automatic request (HARQ) signaling for acknowledging whether one or more downlink data channels have been successfully decoded, the one or more UL data channels and the HARQ signaling being configured based on a UL to DL resource ratio associated with a time-division duplex (TDD) subframe configuration. In certain aspects, the UE generates the one or more UL data channels and the HARQ signaling, and transmits the UL data channels and the HARQ signaling using the scheduled resources and in accordance with the TDD subframe configuration.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station, a first indication to disable hybrid automatic repeat request (HARQ) feedback for a number of instances of a multicast transport block (TB). The method also includes receiving, from the base station, a second indication identifying a value of the number of instances of the multicast TB. The method further includes receiving, from the base station, one or more instances of the multicast TB. The method still further includes determining, based on the one or more received instances, whether the multicast TB is recoverable. The method further includes selectively transmitting, to the base station, HARQ feedback after all instances of the multicast TB have been transmitted by the base station based on the determination of whether the multicast TB is recoverable.

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.
