Ultra reliable link design

Abstract

Techniques are described for wireless communication. A first method includes measuring, by a first device, a condition of a wireless channel; and generating at least one channel side information feedback message based on the measured condition of the wireless channel. The at least one channel side information feedback message provides information on a relationship of a set of parameters, including a data rate parameter, an error probability parameter, and at least one of a deadline parameter or a transmission link parameter. A second method includes measuring, by a first device, interference on a wireless channel; identifying an interfering device for the wireless channel based on the measurement; and generating a channel side information feedback message based on the measured interference on the wireless channel. The channel side information feedback message indicates the interfering device for the wireless channel and a correlation of interference from the interfering device with time or frequency.

Description

CROSS REFERENCES[0001]The present application for Patent claims priority to U.S. Provisional Patent Application No. 62 / 027,623 by Ji et al., entitled “Ultra Reliable Link Design,” filed Jul. 22, 2014, assigned to the assignee hereof, and expressly incorporated by reference herein.BACKGROUND[0002]1. Field of Disclosure[0003]Aspects of the present disclosure relate to wireless communications, and specifically to improved channel side information feedback (CSF) reporting.[0004]2. Description of Related Art[0005]Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include code-division multiple access (CDMA) systems, time-division multiple access (TDMA) sys...

AI Technical Summary

Benefits of technology

The present patent relates to improving CSF reporting in wireless communication systems. The techniques described in the patent involve conditioning the reporting of certain parameters on other parameters, such as error probability, data rate, and deadline. The methods may also involve measuring the condition of the wireless channel and transmitting the information to another device in a wireless communication system. The patent provides various means for implementing these techniques, such as instructions for a processor or computer program product. The technical effects of the patent include improved reliability of wireless transmission links, increased efficiency of wireless communication, and better performance in interference mitigation.

Problems solved by technology

When a receiving device and a transmitting device are communicating over a channel, there is a probability (an error probability) that a given transmission will be lost (e.g., not received or properly decoded by the receiving device).

Unfortunately, current CSF reporting may not be robust enough for certain mission-critical services (e.g., medical services, industrial-grade services, and / or military services).
