Problems solved by technology

[0004] However, the WiGig specification does not allow the use of Automatic Repeat Request (ARQ) schemes during broadcast / multicast transmissions
Furthermore, ARQ is not the most effective error control scheme in time-sensitive applications (e.g., multimedia, gaming, etc.), especially when the channel suffers from long outages and slow When the packet loss rate is high

Abstract

A method and apparatus perform forward error correction in a wireless communication device in a wireless communication network. Application layer forward error correction (AL-FEC) capability information is transmitted during a capabilities exchange. A single parity check (SPC) AL-FEC code is applied on a set of k source packets to encode systematic packets for the source packets and at least one parity packet. A header of each encoded packet includes a parity packet indicator. The encoded packets are processed in a media access control (MAC) layer and a physical (PHY) layer for transmission.

Description

technical field [0001] This application relates generally to reliable data transmission over wireless connections, and more particularly to a method for implementing forward error correction (FEC) architecture at the application layer for communication over Wireless Gigabit Alliance (WiGig) links Methods and Equipment. Background technique [0002] The high demand for reliable multimedia transmission over wireless connections presents great challenges to engineers. Typically, video media requires high transfer rates under latency constraints. Additionally, media is sent over broadcast channels, such as streaming of TV channels, or over multicast channels, such as delivering video encapsulated in large files to many users. The properties of these channels, in addition to delay constraints, rule out the option of having a feedback channel for acknowledging the success of the transmission. As a result, in such cases, alternative techniques are required to ensure the reliabil...
