This abstract describes methods and devices for a phase tracking reference scheme used by a single carrier Offset QAM (SC-OQAM) transmitter and receiver. The scheme helps estimate and correct phase errors that occur during communication between the transmitter and receiver, which can be caused by factors like phase noise or carrier frequency offset. The scheme uses PT-RS symbols to track phase errors, but these symbols can be affected by interference.

Abstract

Aspects of the present application provide methods and devices for a phase tracking reference (PT-RS) scheme for use by a single carrier Offset QAM (SC-OQAM) transmitter and receiver to estimate, and correct, phase errors that occur over the communication link between the SC-OQAM transmitter and receiver.

In order to effectively use the PT-RS to estimate and compensate for the phase noise, the interference must be appropriately considered.

Bit Index Explicit Replication Traffic Engineering Egress Protection (18318344)

Inventor Huaimo Chen

Brief explanation

The abstract describes a method used by a network node in a specific type of network domain called Bit Index Explicit Replication Traffic Engineering (BIER-TE) to provide fast egress protection. Egress protection refers to ensuring that network traffic can still be sent out of the network even if the primary exit point fails.

In this method, the network node receives a specific type of data structure called a type length value (TLV) structure. This TLV structure contains information about the backup exit node that can be used if the primary exit node fails. The information includes the bit position of the backup exit node.

Based on this information, the network node generates a forwarding table called the egress protection bit index forwarding table (EP-BIFT). This table includes the backup path to the backup exit node, and it is created using the bit position of the backup exit node.

When the network node is directly connected to the primary exit node, it uses the EP-BIFT to forward packets. This means that if the primary exit node fails, the network node can quickly switch to using the backup path specified in the EP-BIFT to ensure that packets can still be sent out of the network.

In summary, this method allows a network node in a BIER-TE domain to quickly switch to a backup exit node if the primary exit node fails, ensuring that network traffic can still be efficiently routed out of the network.

Abstract

A method implemented by a network node in a Bit Index Explicit Replication Traffic Engineering (BIER-TE) domain is used to provide fast egress protection.

Inventor Ming Zhu

Brief explanation

This abstract describes an application that presents an organic light-emitting display panel and a display apparatus. The panel includes a functional layer with an emissive layer and an optical filter layer. A pixel define layer is placed between adjacent organic light-emitting units in the emissive layer. The optical filter layer consists of black light-shielding blocks and color-blocking blocks arranged alternately.
