Title:
DYNAMIC CONFIGURATION OF STREAM PARAMETERS BASED ON MODULATION SCHEME
Document Type and Number:
WIPO Patent Application WO/2020/214467
Kind Code:
A3
Abstract:
This disclosure provides methods, devices and systems for signaling modulation schemes and stream parameters such that the modulation schemes and stream parameters can be adapted dynamically while maintaining an existing wireless connection. Some implementations include signaling, via a first channel, a set of stream parameters that govern communications on a second channel when a particular modulation scheme is used to modulate the packets transmitted via the second channel. A transmitting device may select a respective set of stream parameters for each of multiple modulation schemes. For example, in addition to an initial modulation scheme and set of stream parameters, the transmitting device can select alternative modulation schemes and sets of stream parameters that are optimized for the respective modulation schemes. The transmitting device signals the modulation schemes and the respective sets of stream parameters via the first channel in advance of switching modulation schemes for the second channel. The transmitting device is enabled to change the modulation scheme and the set of stream parameters on the fly by including an indication of the modulation scheme in the next packet it transmits via the second channel.
