Three-phase-polarity safe reverse link shutdown
First Claim
1. A method for data communications, comprising:
- transmitting a command to a client device over a first data link, the command being encoded in one or more N-phase polarity encoded symbols and comprising an instruction revoking permission to transmit data over a second data link;
determining whether the client device is transmitting over the second data link;
causing the first and second data links to enter a hibernation state when it is determined that the client device is not transmitting on the second data link; and
causing the first and second data links to enter the hibernation state after a delay when it is determined that the client device is transmitting on the second data link, wherein the first and second data links communicate.

Abstract
System, methods and apparatus are described that facilitate data link shutdown between two devices within an electronic apparatus, enabling safe entry into a hibernation mode. A host device transmits a command to a client device over a first data link. If the client device is not transmitting over the second data link, the host devices initiates shut down of the first data link and entry to a hibernation state. A delay may be initiated when it is determined that the client device is transmitting on the second data link. The command may comprise an instruction revoking permission to transmit data over a second data link to cause the client device to terminate communication on the second data link.

31. An apparatus for wireless communication, comprising:
a processing system configured to; transmit a command to a client device over a first data link, the command comprising an instruction revoking permission to transmit data over a second data link; determine whether the client device is transmitting over the second data link; cause the first and second data links to enter a hibernation state when it is determined that the client device is not transmitting on the second data link; and cause the first and second data links to enter the hibernation state after a delay when it is determined that the client device is transmitting on the second data link.
