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.
Claims32
A method that facilitates controlling a transmission power and detecting state disconnect of a first wireless terminal, comprising:
- assigning at least one ON identifier to the first wireless terminal, the at least one ON identifier being associated with a first predetermined subset of transmission units and a second predetermined subset of the transmission units;
- transmitting a power command in at least one transmission unit of the first predetermined subset of transmission units;
- and
- transmitting information as a function of a terminal identifier of the first wireless terminal in at least one transmission unit of the second predetermined subset of transmission units.
The method of 6, wherein the information comprises at least one bit of the scrambling mask, a bit position of the at least one bit within the scrambling mask being a function of the particular transmission unit.
A wireless communications apparatus, comprising:
- a memory configured to retain a terminal identifier associated with a wireless terminal and at least one ON identifier allocated to the wireless terminal, the at least one ON identifier being associated with a first predetermined subset of transmission units and a second predetermined subset of the transmission units;
- and
- a processor configured to issue a power command in at least one transmission unit of the first predetermined subset of transmission units and transmits information from the terminal identifier in at least one transmission unit of the second predetermined subset of transmission units.
A wireless communications apparatus for verifying an identity and controlling transmission power of a wireless terminal, comprising:
- means for assigning a ON identifier to the wireless terminal, the ON identifier being associated with a first predetermined subset of transmission units and a second predetermined subset of the transmission units;
- means for transmitting a power command in at least one transmission unit of the first predetermined subset of the transmission units;
- and
- means for transmitting information associated with the wireless terminal based on a terminal identifier in at least one transmission unit of the second predetermined subset of the transmission units.
A non-transitory machine-readable medium having stored thereon machine-executable instructions, comprising:
- a first instruction set for assigning an ON identifier to a wireless terminal, the ON identifier being associated with a first predetermined subset of transmission units and a second predetermined subset of the transmission units;
- a second instruction set to issue a power command in at least one transmission unit of the first predetermined subset of transmission units;
- and
- a third instruction set to cause transmission of information related to the wireless terminal based upon a terminal identifier in at least one transmission unit of the second predetermined subset of transmission units.
A processor that executes the following instructions:
- assigning an ON identifier to a wireless terminal related to a first predetermined subset of transmission units and a second predetermined subset of transmission units;
- transmitting a power command in at least one transmission unit of the first predetermined subset of transmission units;
- and
- transmitting information based at least in part upon a terminal identifier of the wireless terminal in at least one transmission unit of the second predetermined subset of transmission units.
