Abstract: Methods, systems, and devices for wireless communication are described. A wireless communication device may receive control signaling that indicates a change in one or more radio frequency thresholds for wireless signaling. The wireless communication device may perform, as part of an in-band clipping procedure, noise repetition and noise shaping to reduce a peak-to-average power ratio (PAPR) associated with the wireless signaling. The noise repetition and the noise shaping may include generating a set of values with one or more first values and one or more second values. The one or more first values may be associated with an error margin between a sample of a wireless communication signal and a clipping threshold. The one or more second values may be inversions of the one or more first values. The wireless communication device may apply the set of values to the wireless communication signal to reduce PAPR.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide assisted access to a serving cell for wireless communications. A UE may receive a broadcast system information message from the first cell. The broadcast system information message may include system information usable for communicating with the second cell. Using the received system information, the UE may transmit, to the first cell, a random access channel (RACH) preamble message in order to establish a connection with the second cell. The first cell may transmit, to the second cell in response to receiving the RACH preamble message, a wake-up signal.

Abstract: Apparatuses and methods for on power state transitions are described. An apparatus is configured to receive, from a network node, a DL EOC indication to trigger a status indication. The apparatus is configured to transmit, to the network node and based on the DL EOC indication, the status indication indicative of a status of a buffer or a delay of the UE and an estimated time at which the UE estimates an arrival of a next UL packet. Another apparatus is configured to transmit, to a UE, a DL EOC indication to trigger a status indication. The apparatus is configured to receive, from the UE and based on the DL EOC indication, the status indication indicative of a status of a buffer or a delay of the UE and an estimated time at which the UE estimates an arrival of a next UL packet.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating one or more communication patterns from a base station. The one or more communication patterns may indicate to the UE to adjust one or more parameters for transmitting an uplink communication during a set of time resources, a set of beams, a set of ports, or any combination thereof. During the resources indicated in the one or more communication patterns, the base station may estimate a cross link interference channel between the base station and a second base station. The one or more communication patterns may indicate a hopping pattern for each subband of a bandwidth part. The base station may configure the UE with a timing advance based on the message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, a physical sidelink shared channel (PSSCH) transmission in an uplink slot or in a smaller-bandwidth slot. The UE may transmit, to the second UE and based at least in part on the PSSCH transmission, hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback in a physical sidelink feedback channel (PSFCH) resource of the uplink slot or of the smaller-bandwidth slot based at least in part on a PSSCH-to-PSFCH mapping, wherein a quantity of PSFCH resources differs between the uplink slot and the smaller-bandwidth slot based at least in part on different resource pool bandwidths between the uplink slot and the smaller-bandwidth slot. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) derives a time reversal (TR) precoder based at least in part on an estimated channel between the first UE and a second UE, and sends, to the second UE, a TR-precoded sidelink (SL) positioning reference signal (PRS). The estimated channel may be based on channel state information (CSI) associated with a wideband (WB) reference signal (RS). The TR precoder may be based on transmissions or receptions on a SL communication channel between the first UE and the second UE.

Abstract: Certain aspects of the present disclosure provide techniques for configuring and operating virtual cells including virtual cells operating in non-contiguous subbands. A method that may be performed by a user equipment (UE) includes: receiving signaling indicating a plurality of non-contiguous subbands configured for a virtual cell; and communicating in the virtual cell via the non-contiguous subbands.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may perform a decoding operation on a downlink message for the UE. The UE may store, in a buffer of the UE, decoding information associated with the decoding operation on the downlink message based at least in part on the decoding operation on the downlink message being at least partially unsuccessful. In some examples, the UE may transmit, to a network entity, a report indicating buffer usage information of the buffer of the UE, where the buffer usage information indicates one or more parameters associated with the decoding information stored in the buffer of the UE. In some cases, the buffer usage information may indicate one or more transport blocks for which entries are present in the buffer of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, control signaling indicating a communication frame structure for communications between the UE and the network entity, where the communication frame structure includes a guard band between a first channel and a second channel in a frequency domain. The UE may receive a control message indicating a set of resources for a message between the UE and the network entity, where at least a subset of resources of the set of resources are included within the guard band. The UE may then communicate the message with the network entity within the set of resources and in accordance with a set of parameters that satisfy one or more conditions for performing communications within the guard band.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may employ one or more scheduling constraints to support efficient utilization of techniques for intra-device handling of overlapping scheduled uplink transmissions (e.g., intra-device dynamic resource cancelation and multiplexing) as well as inter-device handling of overlapping scheduled uplink transmissions (e.g., inter-device dynamic resource cancelation and multiplexing). Scheduling constraints may define how a device may apply intra-device and inter-device multiplexing and cancelation rules for various scenarios. For example, a device may apply intra-UE cancelation rules before inter-device cancelation rules. In some examples, later-received grants or uplink preemption indications (ULPIs) may not change a device's previously established decision to drop an uplink transmission. As another example, a device may not expect to receive a grant for an uplink transmission that would arise in subsequent cancelation of that uplink transmission due to a previously-received grant or previously-received ULPI.
