Traffic Shaping Mechanism for UE Power Saving in Connected Mode

摘要

A method of uplink shaping and scheduling request (SR) prohibition in RRC Connected Mode is proposed. A UE applies DRX operation in a wireless network, the UE is in RRC Connection mode. The UE processes a data packet to be sent to the network. The data packet is associated with a traffic type. If the data packet belongs to a normal traffic type, then the UE transmits a scheduling request (SR) to the network. If the data packet belongs to a background traffic type, then the UE buffers the data packet and is prohibited from sending the SR to the network until a triggering condition is satisfied. By reducing the activity of uplink transmission, UE power consumption is improved and signaling overhead is reduced.

1. A method, comprising:
applying a discontinuous reception (DRX) operation by a user equipment (UE) in a wireless network, wherein the UE is in radio resource control (RRC) Connected mode; processing a data packet to be sent to the network, wherein the data packet is associated with a traffic type; transmitting a scheduling request (SR) to the network if the data packet belongs to a normal traffic type; and buffering the data packet if the data packet belongs to a background traffic type, wherein the UE is prohibited from sending the SR to the network until a triggering condition is satisfied.
