Uplink delay budget feedback
First Claim
1. A method that facilitates providing uplink delay budget feedback in a wireless communication environment, comprising:
- determining a lowest delay budget from a plurality of Radio Link Control (RLC) service data units (SDUs);
configuring a portion of a Medium Access Control (MAC) header to include at least one code corresponding to a delay threshold for the lowest delay budget; and
transmitting the MAC header to a base station.

Abstract
Systems and methodologies are described that facilitate signaling and/or utilizing uplink delay budget related feedback in a wireless communication environment. A lowest delay budget associated with a most urgent Radio Link Control (RLC) service data unit (SDU) retained in a buffer of an access terminal can be determined. Further, a portion of a Medium Access Control (MAC) header (e.g., two reserved bits, . . . ) can be configured to carry a code related to a delay threshold corresponding to the lowest delay budget. Moreover, the MAC header can be transferred to a base station. The base station can detect the code carried by the portion of the MAC header, and a delay threshold can be determined as a function of the detected code (e.g., utilizing a radio bearer specific mapping). According to an example, the access terminal can be scheduled for uplink transmission as a function of the delay threshold.
