Abstract

Wireless communications systems and methods related to intra-packet rate adaptation are provided. A first wireless communication device communicates, with a second wireless communication device, an intra-packet modulation coding scheme (MCS) switching configuration. The first wireless communication device receives, from the second wireless communication device, a communication signal including a first data packet based on the intra-packet MCS switching configuration. The first data packet includes at least a first portion encoded by a first MCS and a second portion encoded by a second MCS different from the first MCS.

First claim

What is claimed is:

1 . A method of wireless communication, comprising:
communicating, by a first wireless communication device with a second wireless communication device, an intra-packet modulation coding scheme (MCS) switching configuration; and receiving, by the first wireless communication device from the second wireless communication device, a communication signal including a first data packet based on the intra-packet MCS switching configuration, the first data packet including at least a first portion encoded by a first MCS and a second portion encoded by a second MCS different from the first MCS.

2 . The method of claim 1 , wherein the communicating includes:
transmitting, by the first wireless communication device to the second wireless communication device, the intra-packet MCS switching configuration indicating that the first wireless communication device is capable of switching from the first MCS to the second MCS within the first data packet.

3 . The method of claim 1 , wherein the communicating includes:
receiving, by the first wireless communication device from the second wireless communication device, the intra-packet MCS switching configuration indicating that the first data packet is transmitted based on a switch from the first MCS to the second MCS.

4 . The method of claim 1 , wherein the communicating includes:
transmitting, by the first wireless communication device to the second wireless communication device, the intra-packet MCS switching configuration including timing information for switching from the first MCS to the second MCS within the first data packet.

5 . The method of claim 4 , further comprising:
determining, by the first wireless communication device, the timing information based on an error vector magnitude (EVM) parameter associated with the first wireless communication device.

6 . The method of claim 1 , wherein the receiving includes:
receiving, by the first wireless communication device from the second wireless communication device, the first portion encoded by the first MCS; and receiving, by the first wireless communication device from the second wireless communication device after receiving the first portion, the second portion encoded by the second MCS including a higher MCS order than the first MCS.

7 . The method of claim 6 , wherein the receiving further includes:
receiving, by the first wireless communication device from the second wireless communication device, a third portion of a second data packet encoded by a third MCS; and receiving, by the first wireless communication device from the second wireless communication device after receiving the third portion, a fourth portion of the second data packet encoded by a fourth MCS including a higher MCS order than the third MCS, wherein the first portion and the second portion are associated with a first multiple-input multiple-output (MIMO) stream, and wherein the third portion and the fourth portion are associated with a second MIMO stream different from the first MIMO stream.

8 . The method of claim 1 , wherein the receiving includes:
