Systems and methods for link adaption in wireless communication systems
First Claim
1. A first wireless device, comprising:
- a transmitter configured totransmit a request, to a second wireless device via a communication channel, for the second wireless device to (i) perform link adaptation on the communication channel, wherein performing the link adaptation includes determining parameters associated with an estimated quality of the communication channel, and (ii) determine, based on the parameters, a preferred modulation and coding scheme (MCS); and
a receiver configured to receive a response from the second wireless device via the communication channel, wherein the response received by the receiver of the first wireless device includes the preferred MCS determined by the second wireless device and the parameters,wherein the transmitter is further configured to, based on the preferred MCS determined by the second wireless device and received from the second wireless device at the first wireless device, select an MCS for transmission of data from the first wireless device to the second wireless device via the communication channel.

Abstract
A first wireless device includes a transmitter and a receiver. The transmitter is configured to transmit a request for parameters to a second wireless device via a communication channel, wherein the parameters include at least one of (i) an estimated quality of the communication channel and (ii) a modulation and coding scheme (MCS) for transmission via the communication channel. The transmitter is further configured to, based on at least one of the parameters, select a MCS for transmission to the second wireless device via the communication channel. The receiver is configured to receive a response from the second wireless device via the communication channel, wherein the response includes the parameters.
