Abstract

A method and system are provided to perform channelization in a wireless communication network, wherein the wireless communication network including at least one base station that is communicatively coupled to at least one mobile terminal. A bandwidth of the wireless communication network is divided into a plurality of zones at the base station. Resource blocks are provided at the base station to receive data symbols transmitted in the wireless communication network. A plurality of resource blocks are combined at the base station to form a physical basic channel unit which are allocated to one of the plurality of zones at the base station. A permutation is performed on the physical basic channel unit to form a logical basic channel unit. A channel is provided to communicatively couple the base station and the mobile terminal so that the mobile terminal may send an access grant message and a user identification to the base station to transmit data in the logical basic channel unit.

combining a plurality of resource blocks at the base station to form a physical basic channel unit, wherein the pilot symbol density and the pilot symbol pattern are based on a number of resource blocks combined to form the physical basic channel unit;

allocating the physical basic channel unit to one of the plurality of zones at the base station;

performing a permutation on the physical basic channel unit to form a logical basic channel unit;

providing a channel to communicatively couple the base station and the at least one mobile terminal; and

receiving at the base station, from the at least one mobile terminal, via the channel, a message requesting access to the logical basic channel unit to transmit data.
