the On Duration and Inactivity Timer are of fixed lengths, while the Active-Time is of varying length based on scheduling decisions and UE decoding success. Only On Duration and Inactivity Timer duration are signaled to the UE by the eNB. There is only one DRX configuration used in the UE at any time. The UE applies an On Duration on wake-up from DRX sleep. This is also applicable in the case where the UE has only one service that is being handled through the allocation of predefined resources, allowing other signaling such as RRC to be sent during the remaining portion of the active time. New transmissions can only take place during the Active-Time. PDCCH has not been successfully decoded during the On Duration, the UE follows the DRX configuration. This also applies to the subframes where the UE has been allocated predefined resources. If the UE successfully decodes a PDCCH in the first transmission, the UE stays awake and starts the Inactivity Timer, even if PDCCH is successfully decoded in the subframes where the UE has also been allocated predefined resources, until a MAC control message instructs the UE to re-enter DRX cycle or until the Inactivity Timer expires. If a short DRX cycle is configured, the UE first follows the short DRX cycle and after a longer period of inactivity the UE follows the long DRX cycle; otherwise, the UE follows the long DRX cycle directly. When the DRX cycle is configured, the network detects whether the UE would remain in E-UTRAN coverage by requesting the UE to send periodic signals to the network. 6.13.4 Quality of Service An Evolved Packet System bearer/E-UTRAN Radio Access Bearer (E-RAB)** is the level of gran- ularity for bearer-level QoS control in the EPC/E-UTRAN. As a result, service data flows mapped to the same EPS bearer receive the same bearer-level packet forwarding treatment, e.g., scheduling policy, queue management policy, rate shaping policy, RLC configuration, etc. One EPS bearer/ E-RAB is established when the UE connects to PDN and remains throughout the lifeti
