AI Technical Summary

Problems solved by technology

Without this information, the base station cannot optimally and efficiently prioritize access terminals while meeting delay bound requirements
However, currently, delay information is typically not communicated from the access terminal to the base station
Thus, the base station may know the amount of data in the access terminal's buffer provided by the buffer status report, but lacks information about the length of time that data has been in the buffer

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 026,046, filed February 4, 2008, entitled "UPLINK DELAY BUDGET FEEDBACK IN LTE." The foregoing application is hereby incorporated by reference in its entirety. technical field [0003] The following description relates generally to wireless communications, and more specifically, to providing uplink delay budget feedback in wireless communications systems. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication, eg, voice and / or data may be provided via these wireless communication systems. A typical wireless communication system or network can provide multiple users access to one or more shared resources (eg, bandwidth, transmit power, . . . ). For example, a system may employ various multiple access techniques such as Frequency Division Multiplexing (FDM), Time Division M...
