Signaling QoS requirements and UE power preference in LTE-A networks

摘要

Embodiments for signaling quality of service (QoS) requirements and user equipment (UE) power preference in LTE-A networks are generally described herein. In some embodiments, a power preference indication (PPI) is received at an eNB from a UE to set a power saving preference for the UE. A communication session is established using radio resource control (RRC) messages between the UE and the eNB to identify a preference for QoS configuration for handling traffic provided to the UE by the eNB. The QoS for traffic provided by the eNB to the UE is managed by the eNB based on the identified preference for QoS configuration for handling traffic provided to the UE.

1. A method for signaling quality of service (QoS) requirements and user equipment (UE) power preference in LTE-A networks, comprising:
receiving, at an evolved nodeB (eNB), a message comprising a power preference indication (PPI) from a UE to set a power saving preference for the UE to execute in a low power consumption configuration when handling data traffic provided by the eNB and a QoS preference when handling data traffic provided by the eNB, the message further comprising:
a PPI field comprising a PPI bit that indicates the PPI and a QoS preference indication bit that indicates the QoS preference, in which the PPI bit takes values that specify between a normal power consumption configuration and the low power consumption configuration and the QoS preference indication bit takes values that specify between a high QoS configuration whose use satisfies a QoS guarantee for the UE and a low QoS configuration whose use provides low QoS for the UE in the low power consumption configuration; detecting a conflict between the PPI and the QoS preference in which the conflict causes the UE, in observation of the QoS preference, to consume more power than the low power consumption configuration; and managing, by the eNB, a QoS configuration for data traffic provided by the eNB based on the identified QoS preference such that one of a configuration that is primarily optimized for power saving and a configuration to satisfy the QoS of active traffic is selected to resolve the conflict between the PPI and the QoS preference based on the message.
