Abstract: Compressing translation lookaside buffer (TLB) tags using a TLB metadata buffer in processor-based devices is disclosed herein. In some aspects, a processor-based device provides a memory management unit (MMU) that includes a TLB and a TLB metadata buffer comprising a plurality of TLB metadata buffer entries storing corresponding TLB metadata. The MMU is configured to select a TLB metadata buffer entry for use in accessing the TLB of the processor-based device. After selecting the TLB metadata buffer entry, the MMU stores a pointer to the TLB metadata buffer entry as an active TLB metadata pointer. When the MMU subsequently receives a memory access request comprising a virtual address (VA), the MMU generates a TLB entry in the TLB for the VA, and stores the active TLB metadata pointer as part of the TLB tag of the TLB entry in lieu of the TLB metadata of the TLB metadata buffer entry.

Abstract: This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels.

In some other implementations, the sequence of values may be obtained based on relative locations of the N noncontiguous subcarrier indices in the wireless channel.

Abstract: This disclosure provides systems, methods and apparatuses for a high priority route selection descriptor (RSD) selection timer. A protocol data unit (PDU) session may be established for an application associated with a user equipment (UE). If the PDU session is associated with a lower RSD priority than the highest RSD priority for the application, the UE may initiate an RSD selection timer. After expiration of the RSD selection timer, the UE may try to establish another PDU session for the application with the highest RSD priority for the application. If another PDU session with the highest RSD priority is accepted, the UE may release the initial PDU session with the lower RSD priority and establish a new PDU session with the highest RSD priority. Such implementations may increase data rates, quality of service, and reliability for the application, decrease latency of the application, or decrease power consumption of the UE.

Abstract: This disclosure provides methods and devices for introducing a power save protocol (for example, a lower power mode) for a multi-link devices (MLDs). Some aspects more specifically relate to reducing power consumption in an access point (AP) MLD, and more particularly, to a power save protocol (or a lower power mode) for an AP MLD. In some aspects, an AP MLD may initiate a lower power mode to save power for as long as possible while still maintaining minimal receive (RX) and transmit (TX) functionality. When requested by an associated station (STA), the AP MLD may then transition from the lower power mode to a higher power mode with full RX and TX functionality with a minimal delay. The described techniques may also account for trade-offs and constraints which arise due to different use cases and scenarios as well as different device configurations.
