Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured for discontinuous reception (DRX) operations using wakeup signals. The UE may monitor periodic wakeup signal occasions for wakeup signals and, in the event that the UE detects a wakeup indication that the UE is to initiate an active duration, the UE may power on transmit/receive circuitry for communications with a base station. In an absence of receiving the wakeup indication, the UE may be configured to transmit an uplink reference signal (e.g., a sounding reference signal) to the base station in an inactive duration of a DRX cycle in some cases. The uplink reference signal may be measured at the base station and used to determine one or more parameters for subsequent communications with the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may communicate with a user equipment (UE) or multiple UEs using multicast transmissions, and each of the multiple UEs may use shared resources to transmit feedback. A UE may receive a power control configuration associated with multicast communications and indicating one or more control parameters or weighting factors for uplink feedback. The UE may monitor a set of downlink resources for the multicast message from the base station, and may determine a decoding failure for the multicast message. The UE may determine whether to transmit uplink feedback to the base station based on the received power control parameters, such as adjusting UE transmit power using a weighting factor or other power control parameters. The UE may determine whether to transmit the uplink feedback message indicating the decoding failure based on the power control configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first transmission including encoded bits of a data packet and a second transmission including some or all of the encoded bits of the data packet. The first transmission associated with a first limited buffer rate matching (LBRM) configuration and the second transmission may be associated with a second LBRM configuration. The UE may process the first transmission and the second transmission based on the first LBRM associated with the first transmission being different than the second LBRM associated with the second transmission.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may order assignment indicator values for transmissions for use by feedback information in a feedback message. The UE may receive, during a monitoring occasion, a first control information over a first serving cell and a second control information over a second serving cell, where each control information schedules a respective transmission for a scheduled serving cell. The UE may order assignment indicator values for the transmissions based on indexes associated with the first and second serving cells (e.g., scheduling serving cells), an index associated with the scheduled serving cell, a start time of the transmissions, or some combination thereof, among other examples. The assignment indicator values may be associated with hybrid automatic repeat request acknowledgement (HARQ/ACK) feedback, such that the UE may use the assignment indicator values to construct and transmit a feedback message.

Abstract: This disclosure provides systems, methods, apparatus, and computer programs encoded on a computer storage media for determining a transmit power of an uplink transmission to one or more serving cells in a secondary cell group (SCG). In one aspect, a wireless device may determine a deadline prior to the uplink transmission to the one or more serving cells in the secondary cell group. The wireless device may determine whether to perform a semi-static uplink transmission that is not scheduled by a DCI format to a serving cell in a master cell group. The wireless device may and adjust a transmit power of the uplink transmission to the one or more serving cells in the secondary cell group in response to determining to perform the semi-static uplink transmission to the serving cell in the master cell group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating a master cell group (MCG) maximum power value and a secondary cell group (SCG) maximum power value. The UE may determine whether a combination of the maximum power values satisfies a threshold. The UE may perform a transmission on the SCG using a first transmit power and a transmission on the MCG using a second transmit power, wherein, based on the combination of the MCG maximum power value and the SCG maximum power value satisfying the threshold, the first transmit power is determined based on a time offset, or wherein, based on the combination of the MCG maximum power value and the SCG maximum power value failing to satisfy the threshold, the first transmit power is determined without using the time offset. Numerous other aspects are described.

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 identify a configuration for communications with a base station on a set of component carriers, the configuration including at least a first set of resources on a first component carrier and a second set of resources on a second component carrier. The UE may receive, from the base station, a downlink control information (DCI) message on the first component carrier, the DCI message including one or more field values indicating that the UE is to release the first set of resources on the first component carrier and the second set of resources on the second component carrier. The UE may determine, based on the received DCI message, that the first set of resources and the second set of resources are released.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain measurements related to a plurality of reference signals received by the UE. In some aspects, each of the plurality of reference signals is associated with a different set of quasi co-location (QCL) properties. The UE may determine a QCL property based at least in part on the measurements related to the plurality of reference signals. The UE may determine, based at least in part on the determined QCL property, a QCL relationship among the plurality of reference signals and a physical downlink shared channel (PDSCH). The UE may receive the PDSCH based at least in part on the QCL relationship. Numerous other aspects are provided.
