1. A method of generating control channel messages in a wireless communication system, the method comprising:
- allocating at least a portion of available logical resources to a control channel for forward link, wherein the allocated portion of the available logical resources comprises logical control channel resources that are distinct from logical traffic channel resources allocated for data transmission, wherein a variable amount of logical resources is allocated to the control channel, and wherein logical resources not used for the control channel are available for allocation to one or more other channels;
assigning the logical control channel resources to physical channel resources to obtain assigned physical channel resources, wherein the assigned physical channel resources correspond to combinations of sub-carriers and symbols;
generating at least one message;
encoding the at least one message to generate at least one message symbol; and
transmitting the at least one message symbol on at least a portion of the assigned physical channel resources.

Abstract
A shared signaling channel can be used in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system to provide signaling, acknowledgement, and power control messages to access terminals within the system. The shared signaling channel may comprise reserved logical resources that can be assigned to subcarriers, OFDM symbols, or combinations thereof.

13. An apparatus configured to generate control channel messages in a wireless communication system, the apparatus comprising:
-
a scheduler configured to allocate at least a portion of available logical resources to a control channel for forward link, wherein the allocated portion of the available logical resources comprises logical control channel resources that are distinct from logical traffic channel resources allocated for data transmission, wherein a variable amount of logical resources is allocated to the control channel, and wherein logical resources not used for the control channel are available for allocation to one or more other channels, and to assign the logical control channel resources to physical channel resources to obtain assigned physical channel resources, wherein the assigned physical channel resources correspond to combinations of sub-carriers and symbols; a signaling module configured to generate at least one signaling message; and a transmitter coupled to the signaling module, the transmitter configured to transmit the at least one signaling message utilizing at least a portion of the assigned physical channel resources. - View Dependent Claims (14, 15, 16, 17, 18, 19, 29, 30, 31)

20. An apparatus for generating control channel messages in a wireless communication system, the apparatus comprising:
-
means for allocating at least a portion of available logical resources to a control channel for forward link, wherein the allocated portion of the available logical resources comprises logical control channel resources that are distinct from logical traffic channel resources allocated for data transmission, wherein a variable amount of logical resources is allocated to the control channel, and wherein logical resources not used for the control channel are available for allocation to one or more other channels; means for assigning the logical control channel resources to physical channel resources to obtain assigned physical channel resources, wherein the assigned physical channel resources correspond to combinations of sub-carriers and symbols; means for generating at least one message; means for encoding the at least one message to generate at least one message symbol; and means for transmitting the at least one message symbol on at least a portion of the assigned physical channel resources. - View Dependent Claims (21, 22, 23, 24, 25, 32, 33, 34)

35. A computer program product, comprising:
a non-transitory processor-readable medium comprising; code for causing at least one processor to allocate at least a portion of available logical resources to a control channel, wherein the allocated portion of the available logical resources comprises logical control channel resources that are distinct from logical traffic channel resources allocated for data transmission, wherein a variable amount of logical resources is allocated to the control channel, and wherein logical resources not used for the control channel are available for allocation to one or more other channels, code for causing the at least one processor to assign the logical control channel resources to physical channel resources to obtain assigned physical channel resources, wherein the assigned physical channel resources correspond to combinations of sub-carriers and symbols, code for causing the at least one processor to generate at least one message, code for causing the at least one processor to encode the at least one message to generate at least one message symbol, and code for causing the at least one processor to send the at least one message symbol on at least a portion of the assigned physical channel resources.
