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

[0009]The present disclosure, for example, relates to one or more techniques for improving CSF reporting. The techniques may enable wireless transmission links to be operated with fiber-like link reliability, without sacrificing efficiency. In one set of techniques, CSF reporting may be conditioned on a parameter other than error probability and / or conditioned on multiple parameters. Also, values for a parameter other than data rate may be reported in a CSF report and / or values for multiple parameters may be reported in a CSF report. Furthermore, different parameter values or combinations of parameter values may be reported based on multiple given values for one or more other parameters. In another set of techniques, interference on a wireless channel may be measured, an interfering device responsible for the interference may be identified, and CSF reporting may be modified to include an indication of the interfering device and a correlation of interference from the interfering device with time and / or frequency. In yet another set of techniques, CSF reporting may be modified to indicate a correlation of one or more CSF parameters (e.g., a data rate parameter) with time and / or frequency.

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).
