Abstract
A mobile station and base station are capable of communicating in a wireless network via a set of contiguous or non-contiguous sub-bands. The base station transmits a resource allocation to the mobile station. The resource allocation message includes a sub-band index (SBI) field, a number of messages field, a contiguous allocation indicator field, or a combination of these. Based on the SBI field, one or more of the number of messages field and contiguous allocation indicator field, the mobile station can identify the set of sub-bands allocated to it by the base station.
