User equipment enhancement for diverse data application
Methods for UE enhancements for diverse data application are disclosed. In one embodiment of the invention, the UE applies a discontinuous reception (DRX) or discontinuous transmission (DTX) operation in a wireless network. The UE detects one or more predefined traffic conditions. Based on the detected traffic conditions, the UE either stays in the long DRX state longer or extends the short DRX cycle timer. In other embodiments of the invention, the UE configures an idle mode trigger condition. The UE detects one or more predefined traffic condition. Based on the detected traffic conditions, the UE may restart the inactivity timer. In other embodiments of the invention, the UE detects one or more predefined traffic conditions. The UE adaptively adjusts RLF triggering parameters based on the detected traffic conditions.
1. A method, comprising:
applying a discontinuous reception (DRX) and/or discontinuous transmission (DTX) operation by a user equipment (UE) in a wireless network, wherein the UE is either in a current DRX state of a long DRX state or in a short DRX state;
detecting one or more DRX state transition triggering events that would trigger a DRX state transition, wherein the DRX state transition triggering events include sending or receiving a data transmission, and an expiration of DRX state transition timer;
detecting a plurality of traffic conditions including whether the data transmission exceeds a predefined threshold, whether buffered data for transmission exceeds the predefined threshold, whether the data transmission is for one of predefined logical channels, whether the data transmission is for a predefined logical channel group, whether the data transmission is a predefined specific uplink transmission, whether the data transmission is a predefined specific downlink transmission, whether the UE is in a non-power-saving state, and whether the logical channel is in the non-power-saving state;
extending an inactivity timer when a plurality of the traffic conditions are met by the UE; and
upon expiration of the inactivity timer, entering a short or long DRX cycle.
2. The method of claim 1 , wherein one of the traffic conditions is a network command that prohibits the DRX state transition, and wherein the network command is based on a traffic condition report sent by the UE.
3. The method of claim 1 , wherein the DRX state is the long DRX state, and wherein one of the traffic conditions that prohibits the DRX state transition is background traffic or low QoS traffic.
4. The method in claim 1 , further comprising:
dynamically adjusting the UL transmission occasion period that applies to PUCCH transmission, RACH transmission, or contention based UL transmissions.
5. The method of claim 4 , wherein the UL transmission occasion period is adjusted to a longer period upon detecting at least one of the traffic conditions: the data transmission is larger than a predefined threshold volume, the data transmission is for one of predefined logical channels or one of a predefined logical channel group, and the UE or the logical channel is in a non-power-saving state.
6. The method of claim 1 , further comprising:
sending one or more traffic condition synchronization information by the UE to the wireless network by either MAC control elements or by RRC signaling.
7. The method of claim 6 , wherein the traffic condition synchronization information comprises at least one of: a DRX state, a UE power-saving or non-power-saving state, a background traffic type, a low QoS traffic type, and a short DRX inactivity timer.
