Uplink access request in an OFDM communication environment
The claimed subject matter relates to acquiring channel access in a wireless communication environment. A wireless terminal may transmit first and second sets of tones over respective first and second contiguous transmission periods. The first and second tone sets may be disjoint from each other and may each comprise a number of contiguous tones. The terminal may then refrain from transmitting during a third time period in order to receive a grant signal from a base station in response to the access request. The beginnings of the first time period and the second time period may be a function of a determined uplink transmission time.
