Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications networks may support carrier aggregation such that a user equipment (UE) may operate on both a primary cell using a first frequency range and a secondary cell using a second frequency range. In some cases, a beam failure associated with one or more beams of the secondary cell may be identified by the UE, and a beam failure recovery procedure may be triggered. The UE may send a beam failure recovery request message in an uplink data field of a physical uplink control channel (PUCCH) message to a base station of the primary cell. In response to the beam failure recovery request message, the base station of the primary cell may transmit a response to the UE which includes beam failure mitigation information.

Abstract: This disclosure provides methods, devices and systems for pre-compensation of downlink communication based on a transmission of a request for the pre-compensation from a user equipment (UE). For example, the UE may determine an impairment at the UE that has a greater severity (a greater impact on downlink communication) or is associated with a greater amount of resources for processing relative to a remainder of a set of impairments that is experienced at the UE and the UE may transmit a request for pre-compensation of the impairment by a base station. The base station may transmit feedback to the UE indicating a confirmation of pre-compensation for the impairment by the base station or to deferment of compensation for the impairment back to the UE. If the base station acknowledges pre-compensation for the impairment, the base station may pre-compensate a downlink transmission to the UE for the impairment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive multiple spatial dimension multiplexed (SDM) communications via a single antenna panel of the UE. The UE may perform phase noise correction for the multiple SDM communications based at least in part on phase tracking reference signals received via a single communication of the multiple SDM communications. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may determine, for a user equipment (UE) operating in a mobility state, route information. The BS may transmit, to the UE, information identifying a set of beams based at least in part on the route information. The UE may perform a set of neighbor cell measurements, in connection with movement along the predicted route, using the set of beams. Numerous other aspects are provided.

Abstract: Methods related to wireless communication systems and communication with dynamic switching between coherent and non-coherent modulation for are provided. A first wireless communication device transmits, to a second wireless communication device based on a coherent modulation mode, a first communication signal including coherently modulated first information data. The first wireless communication device transmits, to the second wireless communication device based on a non-coherent modulation mode, a second communication signal including non-coherently modulated second information data. Other features are also claimed and described.

Abstract: A base station may multiplex a peak suppression information message (PSIM) on a physical downlink shared channel (PDSCH) with data for efficient implementation of PSIMs for peak to average power ratio (PAPR) reduction. A base station may clip peaks from a signal to be transmitted and capture information of the clipped peaks into a PSIM. The base station may then multiplex the PSIM on the PDSCH such that a receiving device (for example, a user equipment (UE)) may receive the signal and reconstruct the signal (for example, PDSCH data) using the PSIM. According to some aspects, each PDSCH symbol may include a PSIM for a previous PDSCH symbol, or the PSIM may be for the current symbol. Various aspects of the techniques described herein may further provide for PSIM positioning in frequency, PSIM modulation, PSIM channel coding, PSIM multiple-input multiple-output (MIMO) configurations, among other examples.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that tone reservation is to be applied to one or more subcarriers for one or more downlink communications. The UE may transmit one or more uplink signals, using the one or more subcarriers, for measurement by a base station. The UE may receive the one or more downlink communications having the tone reservation applied to the one or more subcarriers, the one or more subcarriers having tone reservation applied based at least in part on the measurement of the one or more uplink signals on the one or more subcarriers. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless networks may maintain up-to-date location information for the UE by periodically determining the location the UE using a low power transponding mechanism while the UE is in an inactive state. The UE may monitor a first beam to receive one or more transponder search signals during one or more transponder occasions, and between paging attempts from one or more of the base stations of the network. The UE may receive the one or more transponder search signals, and may transmit a transponder response message to a base station including a UE identifier associated with the inactive state. The base station may receive the transponder response message, and may conduct various location measurements for the UE using the transponder response.

Abstract: Methods, systems, and devices for wireless communications are described. An access device in a network of access devices may determine that a wireless device is in a coverage area of one of the access devices based on a coverage pattern of the access devices and a sensor coupled with the access device. The access device may estimate a trajectory of the wireless device based on information obtained by the sensor. After estimating the trajectory of the wireless device, the access device may transmit an indication to one or more of the other access devices to enter (or remain in) an active state based on the trajectory of the wireless device and the coverage pattern. The indication may also include a set of beams for the other access device to activate.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration of random access resources from a base station. The configuration may indicate a quantity of a plurality of random access preambles, a quantity of a plurality of synchronization signal blocks (SSBs), and a quantity of random access preambles per SSB. The received configuration may indicate that each random access preamble of the plurality of random access preambles is available to the UE in the random access occasion for each SSB of a plurality of SSBs transmitted by the base station. The UE may select a random access preamble of the plurality of random access preambles based at least in part on the received configuration and transmit the selected random access preamble to the base station in the random access occasion.
