Abstract: Aspects of the present disclosure relate to wireless communication systems, and in particular, to techniques for generation and processing of an embedding representing a beam for communication. Certain aspects provide a method for wireless communication by a wireless node. The method generally includes receiving an embedding representing a characterization associated with a beam; providing the embedding to a machine learning (ML) model; generating one or more communication parameters for communication using the beam via the ML model based on the embedding; and communicating using the one or more communication parameters.

Abstract: In some aspects, the present disclosure provides methods, apparatuses, and systems for efficient thermal mitigation while maintaining wireless device performance on a primary component carrier (PCC). Embodiments described may include implementation of target transceiver module configurations, where bandwidth (e.g., PCC bands and secondary component carrier (SCC) bands) may be monitored by a wireless device based on intra-module target configurations and/or inter-module target configurations. An intra-module target configuration may include a target transceiver module monitoring both PCC bands and SCC bands. An inter-module target configuration may include or refer to a plurality of target transceiver modules together monitoring PCC bands and SCC bands. In scenarios where operating temperatures exceed temperature thresholds, target transceiver module configurations may be implemented to transition PCC bands, SCC bands, or both, from a PCC-resident transceiver module to another transceiver module to reduce the operating temperatures of concern. Various additional and alternative aspects are described herein.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE may partially disable transmissions on a transmission port based on a temperature condition (e.g., chipset temperature or skin temperature exceeding threshold). In a further aspect, the UE may enable the partially disabled transmissions on the transmission port in response to cessation of the temperature condition. In a further aspect, the UE may transmit a capability indication to a base station that indicates that the UE is capable of supporting a transition from a multi-layer (rank-2) communication mode to a single-layer (rank-1) communication mode.

Abstract: Certain aspects of the present disclosure provide techniques for scheduling component carriers and one or more operations on a per NB RF chain basis. A method that may be performed by a user equipment (UE) includes monitoring occurrences of a first number of operations to be performed for a plurality of component carriers (CCs) according to different periodicities, determining a second number of available narrow band (NB) radio frequency (RF) chains, and scheduling, on the available NB RF chains, up to the second number of the operations to be performed for the plurality of CCs based on a scheduling algorithm if the first number is greater than the second number.

Abstract: A wireless communication device can expedite beam scans for beam management. The wireless communication device can perform a beam scan using a first beam reference signal of a synchronization signal block (SSB) and a second beam reference signal associated with a physical broadcast control channel (PBCH) of the SSB. For each synchronization signal block (SSB) index (e.g., transmit beam) monitored by the wireless communication device, the wireless communication device can obtain a respective beam quality metric on each of two or more respective receive beams using at least the first and second beam reference signals. Other aspects, features, and embodiments are also claimed and described.

Abstract: In embodiments, a base station may send to a user equipment (UE) a P3 beam management (BM) channel state information reference signal (CSI-RS) having two ports, and may receive from the UE a P3 BM report in response. The P3 BM report may include a proactive UE beam switch indication and a CSF report corresponding to the best UE beam determined by a UE based on the P3 BM CSI-RS. The base station may determine whether the P3 BM report includes an indication that the UE will perform a beam switch from a first UE beam to a second UE beam, and may determine a UE beam switch slot during which the UE will perform the beam switch. Starting at the beam switch slot, the base station may send a physical downlink shared data channel (PDSCH) transmission to the UE using the adjusted downlink transmission parameters.

In some aspects, a user equipment (UE) may transmit, based at least in part on a transmit configuration, a first communication associated with a first group of logical channels associated with at least a portion of an ON duration of an uplink transmission interval configuration. The UE may transmit, based at least in part on the transmit configuration, a second communication during at least a portion of an OFF duration of the uplink transmission interval configuration, wherein the transmit configuration indicates a first amount of energy for the first communication based at least in part on the first communication being associated with the first group of logical channels and a second amount of energy for the second communication based at least in part on the second communication being associated with a second group of logical channels. Numerous other aspects are provided.
