Abstract

Systems and methodologies are described that facilitate effectuating a random access procedure in a wireless communication environment. A random access preamble can be sent from an access terminal to a base station, and a random access response can be sent from the base station to the access terminal in response. The random access response can allocate resources to be utilized by the access terminal for a scheduled transmission (e.g., message 3,...). Further, a plurality of Transmission Time Intervals (TTIs) can be bundled for the scheduled transmission. Moreover, a payload of the scheduled transmission can be transmitted to the base station from the access terminal within a common Transport Block (TB) using the bundled plurality of TTIs. According to an example, employment of TTI bundling can be controlled on a per network basis, per base station basis, or per access terminal basis.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional No. 61 / 089,816, filed August 18, 2008, entitled "A METHOD AND APPARATUS FOR TTI BUNDLING IN A WIRELESS COMMUNICATION" (A METHOD AND APPARATUS FOR TTI BUNDLING IN A WIRELESS COMMUNICATION) Interest in patent applications. The entirety of the above application is incorporated herein by reference. technical field [0003] The following description relates generally to wireless communications and, more particularly, to bundling transmission time intervals (TTIs) for use in random access procedures practiced in wireless communication systems. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication; for example, voice and / or data can be provided over these wireless communication systems. A typical wireless communication system, or network, may provide multiple users with access to one or more shared resources (eg, b...
