Enhancement for Scheduling Request Triggering Based on Traffic Condition
First Claim
1. A method for a user equipment (UE), comprising:
- detecting a traffic condition;
determining a modified scheduling request (SR) trigger based on the traffic condition; and
transmitting a scheduling request to a base station based on the modified SR trigger, wherein the scheduling request is transmitted via a physical uplink control channel (PUCCH) or a random access channel (RACH).

Abstract
A method for scheduling request triggering based on traffic condition is provided. The method supports detecting a traffic condition, determining a modified scheduling request (SR) trigger based on the traffic condition and transmitting a scheduling request to a base station based on the modified SR trigger. In one embodiment, the modified SR trigger is a data buffer or a data generation rate exceeding a threshold. In one embodiment, the threshold is related to a prioritized Bit Rate (PBR) or a bucket Size Duration (BSD) or both. In another embodiment, the threshold is configured by the base station based on a size of the smallest grant under the traffic condition. In one embodiment, the threshold is updated when DRX state changes. In another embodiment, during DRX sleep state, the SR period is longer or SR is stopped.

7. A method for a user equipment (UE), comprising:
-
detecting a traffic condition, wherein the UE is configured for Discontinuous Reception (DRX) mode for power saving, and wherein the traffic condition indicates whether the UE is in DRX sleep time; determining a modified scheduling request (SR) trigger based on the traffic condition; and transmitting a scheduling request based on the modified SR trigger, wherein the scheduling request is transmitted via a physical uplink control channel (PUCCH) or a random access channel (RACH). - View Dependent Claims (8, 9, 10, 11)

12. A user equipment (UE) in a mobile communication network, comprising:
-
a traffic detection module that detects a traffic condition, wherein the traffic condition indicates whether the UE is in a background traffic mode in RRC_CONNECTED state; a scheduling request module that determines a modified scheduling request (SR) trigger based on the traffic condition; and a transmitter that transmits a scheduling request based on the modified SR trigger. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
