Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.

Abstract: Certain aspects of the present disclosure provide techniques for resource allocation and hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback for multi-cell scheduling. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a configuration for a plurality of carriers, receiving, from the BS, control information indicating whether resources for a data channel are allocated in a concatenated pair of carriers of the plurality of carriers, and communicating on the data channel with the BS based on the control information.

Abstract: Certain aspects of the present disclosure provide techniques for techniques for bandwidth part (BWP) operations when a user equipment (UE) is configured with multi-cell physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) scheduling. A method that may be performed by a UE includes receiving, from a base station (BS), first downlink control information (DCI) indicating whether resources are allocated for at least one data channel on multiple carriers, the first DCI configuring at least one BWP configuration to be activated on the multiple carriers, interpreting the first DCI based on the at least one BWP configuration to be activated, and communicating with the BS in accordance with the first DCI as interpreted based on the at least one BWP configuration.

Abstract: Apparatus, methods, and computer-readable media for facilitating a programmable smart repeater with in-band control are disclosed herein. An example method for wireless communication at a repeater includes establishing a control link with a control node and receiving, via the control link, a configuration of one or more parameters of the repeater to forward communication between a first wireless device and a second wireless device. The example method also includes transitioning an MT component of the repeater to a power saving mode for at least a period of time after receiving the configuration and forwarding the communication between the first wireless device and the second wireless device based on the one or more parameters in the configuration. The disclosed techniques may enable reduction in control signaling between the control node and the repeater to provide power savings for the MT of the repeater and lower signal overhead for the control node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, an indication of a transmission on a sidelink resource from the first UE to the second UE. The UE may transmit, to the second UE, data on the sidelink resource based at least in part on the indication of the transmission. Numerous other aspects are provided.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for Type 3 HARQ-ACK codebook enhancements for URLLC. A UE may receive a configuration for reporting HARQ-ACK feedback for a subset of HARQ process IDs included in a set of HARQ process IDs. The set of HARQ process IDs may be associated with a Type 3 HARQ-ACK codebook. The subset of HARQ process IDs may be associated with a modified Type 3 HARQ-ACK codebook that is smaller than the Type 3 HARQ-ACK codebook. The UE may receive, based on the configuration, a trigger for the modified Type 3 HARQ-ACK codebook and report, based on the trigger, the modified Type 3 HARQ-ACK codebook including the HARQ-ACK feedback for the subset of HARQ process IDs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a report that includes measurements associated with one or more downlink reference signals that are received using a set of candidate downlink beams. The UE may transmit one or more uplink reference signals using a set of candidate uplink beams. The UE may receive, from the base station, information that indicates, among the set of candidate downlink beams and the set of candidate uplink beams, a best uplink beam to use for one or more uplink transmissions. For example, the base station may select the best uplink beam based at least in part on the measurements associated with the one or more downlink reference signals and measurements associated with the one or more uplink reference signals. Numerous other aspects are provided.

Abstract: Generating, by a user equipment (UE) of a wireless access network, for a set of contention-based random access occasions of a base station of the network, a random number over an interval. For the generated random number meeting a threshold value within the interval, transmitting, by the UE and to the base station, a random access preamble within one of the random access occasions of the set. For the generated random number not meeting the threshold value, attempting, by the UE, contention-based access to the network within a subsequent set of random access occasions of the base station, the subsequent set of random access occasions occurring after the set of contention-based random access occasions of the base station.
