PACKAGE SUBSTRATES EMPLOYING PAD METALLIZATION LAYER FOR INCREASED SIGNAL ROUTING CAPACITY, AND RELATED INTEGRATED CIRCUIT (IC) PACKAGES AND FABRICATION METHODS (17656477)

Inventor Joan Rey Villarba Buot

Brief explanation

The abstract describes a new type of package substrate for integrated circuits (ICs) that allows for increased signal routing capacity without increasing the overall thickness of the IC package. This is achieved by using a thinner outer metallization layer, called a pad metallization layer, which includes metal pads for external connections. By using this pad metallization layer, more space is available in the adjacent metallization layer for signal routing within the package substrate. This increases the overall signal routing density without adding a full-sized additional metallization layer, which would make the package thicker.

Abstract

Package substrates employing a pad metallization layer for increased signal routing capacity, and related integrated circuit (IC) packages and fabrication methods. To support increased signal routing density in an IC package while mitigating an increase in overall IC package thickness, an outer metallization layer of the package substrate is provided as a thinner, pad metallization layer. A metal layer in the pad metallization layer includes metal pads for forming external connections to the package substrate. This allows an area in the adjacent metallization layer that would otherwise have larger width metal pads for forming external interconnects, to be used for other signal routing within the package substrate. This can increase the overall signal routing density of the package substrate while mitigating the increase in overall package substrate thickness if a full-sized additional metallization layer were added to the package substrate.

It can store basic safety messages and sensor data for a certain amount of time before discarding them. When a collision is detected, the OBU sends a report with the stored information to a server. It can also request other vehicles to upload relevant collision information. If one vehicle detects a collision involving another vehicle, it can communicate this information to other entities and a server.

Abstract

A communication device mounted on a vehicle, e.g., On-Board Unit (OBU), communicates collision related information to other road entities, e.g., other vehicles or roadside units (RSUs) or a server, after a collision is detected. The OBU may temporarily store basic safety messages (BSMs) (and optionally sensor data) for a predesignated number of seconds before discarding the BSMs (and optionally sensor data) on a continuing basis. When a collision is detected, the OBU sends a report, e.g., to a server, with the stored BSMs (and optionally sensor data) to a server. After a collision detection, the OBU may send a request to other vehicles to upload relevant collision related information. Additionally, if a first vehicle detects the collision of a second vehicle, the first vehicle may communicate collision related information to other entities and a server.

Brief explanation

This abstract describes techniques for using positioning reference signals (PRS) in full duplex scenarios. In a wireless communication method, a user equipment (UE) receives a positioning reference signal that covers a certain frequency range. During the same time slot, the UE also transmits a signal in a different frequency range that overlaps with the first frequency range. The UE then processes the received positioning reference signal, excluding the frequencies that were used for transmission.

Inventor Weimin DUAN

Brief explanation

This abstract describes systems and techniques for wireless communications. It introduces the concept of resource allocation for joint communications and RF sensing of objects. The abstract explains that a radar receiver can determine the accuracy of its sensing measurements based on measurements associated with a target. It can then transmit a message to a network entity, indicating the need to modify the allocation of sensing resources for communications data. The network entity receives this message and determines the allocation of sensing resources for the communications data. The radar receiver then receives resource allocation signaling from the network entity based on the indication to modify the allocation of sensing resources.

CHANNEL SENSING FOR DYNAMIC FREQUENCY SELECTION (DFS)-ASSISTED SIGNALS (18252665)

Inventor Siyi CHEN

Brief explanation

The abstract describes a wireless communication system where a base station detects a channel using a sensing time period. If the base station receives a dynamic frequency selection (DFS) signal from a user equipment (UE) during this time period, it decides not to communicate on the corresponding beam or channel for a certain period of time. This decision is based on the beam or channel being added to a non-occupancy list. The abstract mentions that there are other aspects of the disclosure that are described as well.

METHODS TO HANDLE SLICING ACCOUNTING FOR EVOLVED PACKET DATA GATEWAY WI-FI ACCESS (18325832)

Inventor Juan Zhang

Brief explanation

The abstract describes methods, systems, and devices for wireless communications. It explains that a user equipment (UE) can connect to a base station in a cellular radio network. The UE receives an access policy from the cellular radio network, which specifies a preference for the UE to connect to a core network function through a non-cellular radio network. However, the UE finds that the gateway between the non-cellular radio network and the core network function is not configured, and the gateway selection policy of the cellular radio network is also not configured. As a result, the UE establishes a connection to a legacy core network function of a legacy cellular radio network through a legacy gateway.

NEW BEAM IDENTIFICATION FOR PHYSICAL DOWNLINK CONTROL CHANNEL (PDCCH) REPETITION (18018634)

Inventor Yan Zhou

Brief explanation

This disclosure presents systems, methods, and apparatus for identifying beams for the physical downlink control channel (PDCCH) repetition.
