Physical HARQ indicator channel (PHICH) resource assignment signaling in a wireless communication environment
First Claim
1. A method that facilitates disseminating Physical Hybrid Automatic Repeat Request (HARQ) Indicator Channel (PHICH) resource assignments in a wireless communication environment, comprising:
- encoding at least a portion of a current PHICH resource assignment for a current Transmission Time Interval (TTI) and at least a portion of a subsequent PHICH resource assignment for a subsequent TTI within a common encoded signal; and
transmitting the common encoded signal to an access terminal during the current TTI.

Abstract
Systems and methodologies are described that facilitate signaling Physical Hybrid Automatic Repeat Request (HARQ) Indicator Channel (PHICH) resource assignments in a wireless communication environment. At least a portion of a current PHICH resource assignment for a current Transmission Time Interval (TTI) and at least a portion of a subsequent PHICH resource assignment for a subsequent TTI can be encoded within a common encoded signal. Further, the common encoded signal can be sent to an access terminal during the current TTI. For instance, the common encoded signal can be transmitted via a Physical Broadcast Channel (PBCH). Alternatively, the common encoded signal can be sent through dedicated Radio Resource Control (RRC) signaling during handover. The access terminal can decode the common encoded signal received from the base station to identify the current PHICH resource assignment (or portion thereof) and the subsequent PHICH resource assignment (or portion thereof).
