A random access preamble can be received from the UE based on the random access procedure timeline, and a response to the random access preamble can be determined or transmitted based on the random access procedure timeline.

Abstract: A victim user equipment (UE) may experience cross-link interference (CLI) from transmissions from an aggressor UE. The present disclosure provides for configuration of a CLI report that accurately characterizes the CLI experienced by the victim UE. A base station may transmit to the victim UE, a configuration for CLI reporting associated with one or more channel state information interference measurement (CSI-IM) resources. The victim UE may generate a CLI report based on the configuration for CLI reporting and the CSI-IM resources. The victim UE may transmit the CLI report to the base station. The base station may use the CLI report to mitigate the CLI, for example, by scheduling the aggressor UE and the victim UE to reduce CLI experienced by the victim UE.

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: Methods, systems, and devices for wireless communication are described. A method at a user equipment (UE) includes receiving signaling that indicates a carrier aggregation (CA) configuration (having carriers configured for UL and downlink (DL) data transmissions) and an auxiliary uplink (UL) configuration (having carriers configured for UL reference signal transmissions). The method also includes receiving a resource assignment on a DL carrier of the CA configuration, and transmitting an aperiodic sounding reference signal (A-SRS) using the one or more carriers of the auxiliary UL configuration based at least in part on the received resource assignment. Another method is performed by a UE having a CA configuration and an A-SRS configuration, including receiving a resource assignment on a DL carrier in the CA configuration, detecting a trigger for transmitting an A-SRS, determining UL resources of the A-SRS configuration for transmitting the A-SRS, and transmitting the A-SRS on the determined UL resources.

A method that may be performed by a user equipment (UE) generally includes receiving at least one reference signal (RS), performing an RS measurement based on the at least one RS, and transmitting, to a base station (BS), at least one first message indicating a recommendation for SRI selection determined based on the RS measurement.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify and schedule a set of bits in the physical uplink shared channel (PUSCH) for transmission of feedback for downlink transmissions occurring after transmission of the uplink grant scheduling the PUSCH. After receiving the uplink grant, a user equipment (UE) may receive control channel (PDCCH) transmissions that schedule downlink transmissions. The UE may monitor for and generate feedback for the downlink transmission. The UE may then utilize the bits indicated by the UL grant to transmit the feedback. In some examples, the UE may determine whether the indicated bits are adequate to transmit the feedback for the later downlink transmissions. When the UE determines that the extra bits are not adequate (e.g., there are not enough bits), then the UE may determine to transmit the feedback separate from the PUSCH resources scheduled by the uplink grant.

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.

In aspects, a UE may receive, from a base station, DCI including a request for HARQ-ACK feedback associated with at least one resource that is unavailable. The HARQ-ACK feedback may be based on one or more one-shot HARQ-ACK codebooks including one or more bits. The UE may transmit, to the base station, the HARQ-ACK feedback associated with the at least one resource that is unavailable, where the HARQ-ACK feedback includes the one or more one-shot HARQ-ACK codebooks including the one or more bits.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein relate to a user equipment (UE) that may include a wakeup radio in addition to a main radio to monitor for wakeup signals while the UE is in a sleep mode. The wakeup radio receiver may use less power than the main radio. In some examples, a first UE may indicate to a wireless node (e.g., a controlling sidelink UE or a network entity) that the UE is capable of sending wakeup signals to a second UE. In such examples, the wireless node may transmit a wakeup signal intended for the second UE to the first UE based on the capability report. The first UE may relay the wakeup signal to the second UE. Responsive to receiving the wakeup signal, the second UE may wake up the main radio of the second UE for communications.

The base station may transmit a first control message to the UE to indicate a set of downlink resources for a downlink message associated with the subband uplink precoding information for the UE. The base station may transmit a second control message to the UE to indicate a set of uplink resources for an uplink message. The base station may transmit the downlink message to the UE via the set of downlink resources indicated by the first control message. The downlink message, the second control message, or both may include the subband uplink precoding information for the UE. The UE may transmit an uplink message to the base station via the set of uplink resources using the subband uplink precoding information.
