Abstract: In an aspect, a user equipment (UE) obtains, during a positioning procedure with a location server, one or more positioning measurements of one or more positioning reference signal (PRS) resources transmitted by one or more network nodes, applies a machine learning model to at least the one or more positioning measurements to obtain one or more predicted future positioning measurements associated with the one or more network nodes, and transmits positioning information to the location server. This positioning information includes the one or more positioning measurements and the one or more predicted future positioning measurements, a current position of the UE determined based, at least in part, on the one or more positioning measurements and a predicted future position of the UE determined based, at least in part, on the one or more predicted future positioning measurements, or both.

Abstract: Techniques are discussed herein for transmission of location information by a user equipment (UE) to other UEs. A UE receives Satellite Positioning System (SPS) signals and determines whether the SPS signals are reliable. The UE determines a location estimate to be transmitted to other UEs using the SPS signals if the SPS signals are determined to be reliable and using non-SPS information if the SPS signals are determined to be not reliable. The location information is transmitted to other UEs in a message that includes an indication of the source of information used to generate the location estimate. A UE that receives the message may determine its location estimate based, at least in part, on the indication of the source of information, e.g., by determining whether SPS signals are reliable based, at least in part, on the indication of the source of information received in the message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication, and to channel aware modulation order selection for wireless communications. For example, a user equipment (UE) may transmit one or more channel-related parameters to a network node. The network node may select a modulation order in accordance with the one or more channel-related parameters and one or more network parameters that are transmitted to the UE. The network node may modulate a bitset in accordance with the modulation order to generate a modulated bitstream that is transmitted to the UE. The UE may select the same modulation order in accordance with the one or more channel parameters and the one or more network parameters received from the network node, such that the UE may demodulate the modulated bitstream in accordance with the modulation order to generate a demodulated bitset.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may convey uplink control information (UCI) to a base station using a multi-slot or single slot uplink channels. In some cases, however, transmissions scheduled on a first set of resources allocated for multi-slot transmission of a first uplink channel may overlap with one or more slots of a second set of resources allocated for multi-slot transmission of a second uplink control channel. Accordingly, the UE may employ a number of different techniques to transmit the UCI. In a first case, the UE may map the UCI to at least one of the overlapping slots of the first uplink channel. In a second case, the UE may drop the second uplink channel which carries the UCI. In a third case, and the UE may map the UCI to an overlapping slot of the second uplink channel.

The UE may perform channel estimation for the broadcast channel in accordance with one or more delay spread values associated with a multi-path profile of the broadcast channel, where the one or more delay spread values are based at least in part on the first delay value associated with the small delay CDD scheme. The UE may receive a message via the broadcast channel based at least in part on performing the channel estimation.

Abstract: This disclosure provides methods, components, devices and systems for channel access techniques in a multi-hop framework for ultra-high reliability (UHR). Some aspects more specifically relate to a transmission opportunity (TXOP) sharing mechanism according to which wireless communication devices can relay data frames along multiple hops within a same TXOP, a coordinated medium access scheme associated with relaying data frames between a root access point (AP) and a wireless station (STA) via multiple service periods, and various signaling mechanisms and frame formats according to which wireless communication devices can exchange or negotiate information associated with a coordinated medium access scheme. In some implementations, a coordinated medium access scheme may be associated with multiple time epochs (each associated with a service period) and differentiated channel access across the multiple time epochs may facilitate the relay with or without TXOP sharing within the associated service periods.

Abstract: This disclosure provides systems and methods for requesting wireless resources for peer-to-peer (P2P) communications. In some implementations, a wireless communication device transmits a frame over a wireless medium to an access point (AP), the frame including a medium access control (MAC) header carrying a request for the AP to allocate part of a transmission opportunity (TXOP) for P2P communications between the wireless communication device and a client device. The wireless communication device receives a trigger frame allocating a portion of the TXOP for the P2P communications, and transmits or receives P2P data to or from the client device over the wireless medium during the allocated portion of the TXOP. In some instances, the MAC header of the frame includes a Quality-of-Service (QoS) Control field carrying the request. In some other instances, the MAC header of the frame includes an Aggregated-Control (A-Control) subfield carrying the request.

Abstract: This disclosure provides methods, components, devices and systems for overlapping physical layer protocol data unit (PPDU) end point offset. Some aspects more specifically relate to staggering the end times of overlapping PPDUs transmitted by multiple access points (APs) such that the corresponding block acknowledgments (BAs) are staggered by durations exceeding BA locking periods for the APs. In some examples, a BA may be transmitted by a wireless station (STA) to an AP a short interframe space (SIFS) after the end time of a PPDU transmitted by the AP. When multiple APs transmit concurrent PPDUs, multiple STAs may accordingly transmit corresponding BAs. By implementing techniques to stagger the BAs, an AP that locks onto a BA and determines that the BA is intended for another AP can receive a next staggered BA intended for the AP.

Abstract: A self-aligned contact (SAC) and method for making the same is disclosed. In an aspect a field effect transistor (FET) structure comprises a channel connecting a first source or drain (S/D) region to a second S/D region, a gate structure, comprising a multi-layer metal gate between gate spacers, disposed above a gate region that at least partially surrounds the channel, a self-alignment structure, also referred to as a “hat”, disposed above the gate structure and covering at least the multi-layer metal gate and the gate spacers, and a first S/D contact that is self-aligned to the hat and connected to the first S/D region.

Abstract: Deep vias may be employed on a die to connect transistor circuits on a front side to a power distribution network on a back side. Deep vias extending from a second die surface to a first die surface over an entire length may have high resistance interfaces to circuit interconnects that couple the deep vias to transistor circuits. Deep vias adjacent to transistor channel regions in the transistor circuits may also cause unwanted capacitance. An exemplary deep via includes an interface region and at least one non-interface region, where the interface region includes an interface between the deep via and a circuit interconnect, and the at least one non-interface region extends a second distance that is less than the distance between the first die surface and the second die surface. In this manner, capacitance is reduced, and resistance may be reduced.
