Abstract
An apparatus is disclosed having a receiver configured to communicate, by a first apparatus, with a second apparatus in a first mode; determine side information by the first apparatus based on the communication during the first mode; and store the side information by the first apparatus for communication in a second mode with the second apparatus, wherein the first and second modes of communication have different date rates. A method for wireless communications is also disclosed.
Claims19
A method of wireless communications comprising:
- communicating, by a first apparatus, with a second apparatus in a first mode, wherein the first mode comprises a pairing of the first and second apparatuses in a channel environment associated with a first SNR;
- determining device information by the first apparatus based on the communication during the first mode;
- and
- storing the device information by the first apparatus for communication in a second mode with the second apparatus, wherein the second mode comprises a data exchange between the first and second apparatuses in a channel environment associated with a second SNR, wherein the first SNR is greater than the second SNR, and wherein the first and second modes of communication have different data rates.
