METHODS AND APPARATUS OF IMPLEMENTING AND/OR USING A CONTROL CHANNEL
First Claim
1. A method of operating a wireless terminal comprising:
- using a first control subchannel allocated by a base station to the wireless terminal, said first control subchannel including a first set of control channel segments during a first time period, said first set including a first number of control channel segments; and
receiving a mode control signal from the base station, said mode control signal commanding said wireless terminal to switch from a first mode of operation to a second mode of operation, wherein during the second mode of operation, said first set of resources comprises a different amount of control channel segments per unit time than during said first mode of operation.

Abstract
Wireless terminals and base stations support multiple modes of dedicated control channel operation wherein wireless terminals are allocated different amounts of dedicated uplink resources for reporting control information. A set of dedicated control channel segments is utilized by a wireless terminal to communicate uplink control information reports to its serving base station attachment point. Full tone and split-tone modes of dedicated control channel operation are supported. In full tone mode, a single wireless terminal is allocated each of the dedicated control channel segments associated with a single logical tone. In split tone mode, dedicated control channel segments associated with a single logical tone are allocated between different wireless terminals, with each of the multiple wireless terminals receiving a different non-overlapping subset of the dedicated control channel segments. Logical dedicated control channel tones can be dynamically reallocated for full-tone mode use or split tone mode use.
