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.

Embodiments of the present disclosure are directed to link adaptation, such as for physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH), in cases where channel state information (CSI) is available, as well as in cases where CSI is unavailable. Other embodiments may be disclosed and/or claimed.

Implementations disclosed describe techniques and systems to facilitate efficient operations of wireless networks organized in a topology of communicating nodes. Techniques include cascade synchronization of various nodes of the network by generating and maintaining a common time using times associated with ordered communications between nodes. The common time maintained by the network allows performance of synchronous action for precise industrial, medical, and testing applications. The described techniques and systems further include management of communication windows between different nodes in a way that facilitates fast and efficient propagation of data collected by the network from multiple source nodes to one or more destination nodes. The techniques further include efficient assignment and flexible management of communication frequencies (channels) to various nodes of the network to reduce interference and noise by assigning different communication frequencies to the nodes that utilize concurrent communications windows.

Some embodiments of the invention provide a method for evaluating multiple candidate resource elements that are candidates for deploying a set of one or more tenant deployable elements in a public cloud. For each particular tenant deployable element, the method deploys in the public cloud at least one instance of each of a set of one or more candidate resource elements and at least one agent to execute on the deployed resource element instance. The method communicates with each deployed agent to collect metrics for quantifying performance of the agent's respective resource element instance. The method then aggregates the collected metrics in order to generate a report that quantifies performance of each candidate resource element in the set of candidate resource elements for deploying the particular tenant deployable element in the public cloud.
