TTI bundling in a random access procedure

摘要

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.

主权项

1. A method that facilitates performing random access in a wireless communication environment, comprising:
transmitting a random access preamble to a base station; receiving a random access response from the base station in response to the random access preamble, the random access response having an indicator that indicates whether to bundle a plurality of Transmission Time Intervals (TTIs) for a scheduled transmission; determining whether to bundle the plurality of TTIs for the scheduled transmission based upon the indicator included in the random access response and an uplink bandwidth; selectively bundling the plurality of TTIs for the scheduled transmission when a determination is made that the uplink bandwidth is less than a threshold value; and transmitting a payload of the scheduled transmission to the base station within a common Transport Block (TB) using the bundled plurality of TTIs.
