Abstract: Certain aspects of the present disclosure provide techniques for a configurable mode for a response to random access message. A method that may be performed by a user equipment (UE) includes receiving an indication from a base station (BS) that the BS operates according to a first mode in which the BS unicasts a RACH response during a two-step RACH procedure or a second mode in which the BS multicasts the RACH response. The RACH response includes a PDCCH and PDSCH. The UE sends a RACH message to the BS comprising a preamble and payload. The UE monitors and decodes the PDCCH of the RACH response based on the indicated first mode or second mode. The UE decodes the PDSCH of the RACH response and sends feedback to the BS based on the indicated first mode or second mode.

Abstract: Aspects relate to supporting power control for physical uplink control channel (PUCCH) transmissions on an uplink secondary component carrier (SCC) of a wireless communication system. In some aspects, a user equipment (UE) receives a power control configuration from a base station for use by the UE for a PUCCH transmission on a selected uplink SCC. The UE then transmits, based at least in part on the power control configuration, the PUCCH to the base station on the selected uplink SCC. Closed-loop and open-loop power control examples are provided. In some aspects, common or shared power control configurations are provided by the base station for use with each component carrier of a PUCCH group. In other aspects, carrier-specific power control configurations are provided by the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be capable of operating according to a first transmission efficiency operating mode and a second transmission efficiency operating mode that is less power efficient than the first transmission efficiency operating mode. The first transmission efficiency operating mode may be associated with a first undesired emission level that is greater than a second undesired emission level associated with the second transmission efficiency operating mode. The UE may select to operate in one of the two transmission efficiency operating modes based on one or more communication parameters (e.g., indicated by control signaling received from a base station). For example, the UE may select to operate in the first transmission efficiency operating mode based on determining that one or more of the communication parameters satisfies at least one parameter criterion for operating in the first transmission efficiency operating mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first set of resources associated with a semi-persistent scheduling (SPS) acknowledgement/negative acknowledgement (A/N) feedback message, wherein the SPS A/N feedback message is deferred to a second set of resources by the UE. The UE may receive an indication of a third set of resources associated with a dynamic A/N feedback message, wherein the second set of resources and the third set of resources are associated with a collision. The UE may perform an action based on the second set of resources and the third set of resources being associated with the collision. The UE may transmit at least one of the SPS A/N feedback message or the dynamic A/N feedback message based on performing the action. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration identifying a first set of frequency resources for transmitting a sounding reference signal, where the sounding reference signal may be used at least for downlink channel state information acquisition. The UE may receive an indication of an association between the configuration for the sounding reference signal and a second set of frequency resources and determine, based on the association, values for one or more sounding reference signal transmission parameters for the first set of frequency resources. The UE may transmit the sounding reference signal on the first set of frequency resources based on the determined one or more values.

Abstract: Aspects relate to a base station configuring a user equipment (UE) with multiple (e.g., at least two) hybrid automatic repeat request (HARQ) feedback granularities. In some examples, a first HARQ feedback granularity may be for transmitting HARQ feedback in a first quantity of symbols and a second HARQ feedback granularity may be for transmitting HARQ feedback in a second quantity of symbols. The base station may send an indication to the UE that specifies which HARQ feedback granularity the UE is to use for sending HARQ feedback.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a UE capability associated with reference signal reporting by the UE. The UE may receive, from the base station, a data packet and an indication of a mode for hybrid automatic repeat request (HARQ) feedback reporting based on the UE capability. The UE may determine that a slot includes first resources for transmitting a sounding reference signal (SRS) and second resources for transmitting HARQ feedback for the data packet. The UE may transmit, to the base station during the slot and based on the indication of the mode for HARQ feedback reporting, the HARQ feedback and one or more of the SRS or CSI associated with the HARQ feedback.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may group, into a common slot, a first plurality of consecutive uplink slots included in a first component carrier and a second plurality of consecutive uplink slots included in a second component carrier. The UE may determine whether an uplink transmission is scheduled in at least one of the first plurality of consecutive uplink slots or the second plurality of consecutive uplink slots. The UE may transmit on the first component carrier or on the second component carrier in the common slot or determine whether to switch a transmit chain based at least in part on whether an uplink transmission is scheduled in at least one of the first plurality of consecutive uplink slots or the second plurality of consecutive uplink slots. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, or devices for wireless communications may implement receiving a grant for a first transmission scheduled for a first set of resources, the first transmission associated with a first transmission parameter; receiving an indication to cancel the first transmission; dropping the first transmission based on receiving the indication; determining a second transmission parameter for a second transmission based on the first transmission parameter and irrespective of dropping the first transmission; and performing or receiving the second transmission according to the second transmission parameter. Alternatively, a device may receive an indication to cancel the second transmission; drop the second transmission based on receiving the indication; and refraining from rescheduling the first transmission on the first set of resources based on receiving the indication and irrespective of dropping the second transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus for wireless communication at a wireless node comprises one or more memories, and one or more processors, coupled to the memory. The one or more processors can be configured to transmit or receive tri-state feedback indicating a result of decoding one or more communications. The tri-state feedback can be associated with three potential states. The three potential states can indicate whether (i) decoding of a control channel was unsuccessful, (ii) decoding of the control channel was successful and decoding of a data channel was unsuccessful, or (iii) decoding of the control channel and the data channel was successful.
