Abstract: The apparatus in some aspects may be a wireless device configured to operate a first transceiver in a first connected mode with a first radio access network (RAN) and a second transceiver in a second connected mode with a second RAN. The apparatus may further be configured to transmit a first communication via the first transceiver and obtain, based on a second communication via the second transceiver, an indication of a cancellation of one or more symbols for the first communication via the first transceiver. The apparatus may also be configured to refrain from transmitting, based on the indication, a remaining portion of the first communication via a set of symbols including the one or more symbols.

Abstract: Various aspects generally relate to communication. In some aspects, a receiver may receive, from a transmitter over a wired infrastructure, a frequency division multiplexed (FDM) signal. The receiver may map the FDM signal to a spatial division multiplexed (SDM) signal including multiple spatial layers, wherein the SDM signal mapped to the FDM signal compensates for a frequency error between the transmitter and the receiver. The receiver may provide the SDM signal to a multiple-input multiple-output (MIMO) transceiver. Numerous other aspects are described.

Abstract: A data processing system for selecting configurations for virtual functions includes a runtime processor coupled to a reconfigurable processor having arrays of coarse-grained reconfigurable units. The runtime processor receives a virtual function request specifying resource requirements including compute requirements, memory requirements, or performance requirements. The runtime processor analyzes the resource requirements to determine a resource profile characterizing the virtual function's computational needs, evaluates available configuration options that provide different array allocations, and selects a configuration that matches the resource profile to configuration capabilities. Selection is based on comparing the resource profile against capability thresholds, where configurations providing one array per virtual function satisfy low requirements, configurations providing two arrays satisfy medium requirements, and configurations providing four arrays satisfy high requirements.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques may enable a user equipment (UE) to use a frequency estimator (e.g., a maximum likelihood estimator) that may be based on a pilot signal sent over M distinct symbols. That is, the frequency estimator may be based on all available cross-correlations of pilot signals in a reference signal. In some examples, the frequency estimator may achieve an increased pull-in range and estimation performance based on weighting the available cross-correlations in accordance with the channel statistics. The described techniques may also support asymmetrical symbol spacings between pilot signals in one or more reference signals, which may further improve pull-in range of the frequency estimator. Additionally, or alternatively, aspects of the frequency estimator may be combined with aspects of another frequency estimator to increase the pull-in range with relatively low computation complexity at the UE.
