USER SPECIFIC DOWNLINK POWER CONTROL CHANNEL Q-BIT
First Claim
1. A method that facilitates evaluating wireless terminal specific power control information, comprising:
- receiving an ON identifier allocating a first predetermined subset of transmission units and a second predetermined subset of transmission units;
receiving a power command in at least one transmission unit of the first subset of transmission units;
receiving information based at least in part upon a terminal identifier associated with a wireless terminal in at least one transmission unit of the second subset of transmission units;
comparing the received information associated with the wireless terminal to expected information associated with the wireless terminal; and
adjusting a power level based upon the power command when the received information matches the expected information.

Abstract
Systems and methodologies are described that facilitate controlling transmission power of a wireless terminal. A downlink power control channel segment may include an Orthogonal Frequency Division Multiplexing (OFDM) tone-symbol that may comprise a first component and a second component. The first component may be an in-phase (I) component and the second component may be a quadrature (Q) component, for example. A power command may be transmitted in the first component. Further, information associated with a wireless terminal may be transmitted in the second component. The information associated with the wireless terminal may be, for instance, a portion of a scrambling mask associated with the wireless terminal.
