1. A method for wireless communications, comprising:
- determining if a data rate control (DRC) cover received from an access terminal is erased and a DRC erasure criteria related to the DRC cover is met;
determining, if the DRC cover is erased and said DRC erasure criteria is determined met, if a data source control (DSC) value received from the access terminal is erased; and
scheduling transmission for the access terminal from a sector associated with the DRC cover, if the DRC cover is determined not erased.

Abstract
Embodiments disclosed herein relate to methods and systems for server selection during feedback channel impairment in wireless communications. The feedback channel may be provided by a data rate control (DRC) channel, transmitted from an access terminal to an access network relating the selected serving sector (DRC cover) and the desired data rate (DRC rate) for transmission on forward link. During DRC cover erasure (e.g., due to channel impairment), a data source control (DSC) channel may be used as complimentary information to assist the DRC erasure mapping decision at the access network.
