Abstract: A computing system performs shared cache allocation to allocate cache resources to groups of tasks. The computing system monitors the bandwidth at a memory hierarchy device that is at a next level to the cache in a memory hierarchy of the computing system. The computing system estimates a change in dynamic power from a corresponding change in the bandwidth before and after the cache resources are allocated. The allocation of the cache resources are adjusted according to an allocation policy that receives inputs including the estimated change in the dynamic power and a performance indication of task execution.

Abstract: Techniques pertaining to physical-layer (PHY) parameter designs enabling resource unit (RU) duplication and tone repetition for next-generation wireless local area networks (WLANs) are described. An apparatus (e.g., station (STA)) generates an RU or multi-RU (MRU). The apparatus then performs a wireless communication with the RU or MRU. In generating the RU or MRU, the apparatus codes a spatial stream using a binary convolutional coding (BCC) interleaver or a low-density parity-check (LDPC) tone mapper. In performing the wireless communication, the apparatus performs the wireless communication with RU duplication or tone repetition in a frequency domain.

Abstract: Techniques pertaining to channeling state information (CSI) compression are described. A user equipment (UE) that is in wireless communication with a base station node acquires channel state information (CSI) at least associated with the wireless communication. The UE further compresses the CSI into CSI feedback for the base station node via an artificial intelligence (AI)/machine-learning (ML)-based encoder that implements at least one of convolutional projection, expandable kernels, or multi-head re-attention (MHRA).

Abstract: An antenna structure is provided. The antenna structure includes a first metal layer and a second metal layer disposed over the first metal layer. The second metal layer forms a first antenna resonating element operating at a first band and has a first opening. The antenna structure also includes a third metal layer disposed over the second metal layer. The third metal layer forms a second antenna resonating element operating at a second band, which is different from the first band. The antenna structure further includes a first transmission line extending from the first metal layer to the second metal layer and a second transmission line extending from the first metal layer through the first opening to the third metal layer.

Abstract: Disclosed herein are system, method, and computer program product embodiments for reducing GPU load by programmatically controlling shading rates in computer graphics. GPU load may be reduced by applying different shading rates to different screen regions. By reading the depth buffer of previous frames and performing image processing, thresholds may be calculated that control the shading rates. The approach may be run on any platform that supports VRS hardware and primitive- or image-based VRS. The approach may be applied on a graphics driver installed on a client device, in a firmware layer between hardware and a driver, in a software layer between a driver and an application, or in hardware on the client device. The approach is flexible and adaptable and calculates and sets the variable rate shading based on the graphics generated by an application without requiring the application developer to manually set variable rate shading.

Abstract: A transmission interface between at least a first module and a second module is proposed. The transmission interface includes at least two physical transmission mediums. Each physical transmission medium is arranged to carry a multiplexed signal in which at least two signals are integrated. The at least two physical transmission mediums include a first physical transmission medium arranged to carry a first multiplexed signal including a first IF signal and a reference clock signal. The first IF signal and the reference clock signal are at different frequencies.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an access point (AP) multi-link device (MLD). In certain configurations, the AP MLD establishes a primary link on a first channel and a non-primary link on a second channel. The AP MLD determines to perform a channel switch operation to switch a first link of the primary link and the non-primary link to operating on a different channel. The AP MLD transmits, on the primary link and prior to the switching of the first link, a first management frame including a first element indicating a target switching time for the switching of the first link. The AP MLD transmits, on the primary link after the switching of the first link, a second management frame indicating that an AP on the first link is in operation.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE transmits a capability report to a base station. The capability report indicates one or more capabilities of an aggregated mobile terminal (MT) formed by the UE and one or more devices each being a component device. The UE receives configurations of an initial set of reference signals from the base station. The configurations respond to the one or more capabilities. The UE transmits an initial report to the base station. The initial report indicates codebook parameters. The UE receives codebook configurations of a codebook from the base station. The codebook is for generating a downlink precoder matrix for CSI reporting or for generating an uplink precoder matrix for uplink transmission.

Abstract: Various techniques and schemes pertaining to primary link identification schemes in wireless communications are described. An access point (AP) multi-link device (MLD) establishes a plurality of links, the plurality of links comprising a primary link and a non-primary link that constitute a non-simultaneous-transmission-and-reception (NSTR) link pair. An AP affiliated with the AP transmits a beacon frame with an indication on whether or not the AP or a reported AP is affiliated with an NSTR AP MLD and is operating on the primary link of the NSTR link pair.
