    Abstract: A technology for a user equipment (UE) that is operable to connect to a third generation partnership project (3GPP) long term evolution (LTE) cell in a cellular network. Logged minimization of drive test (MDT) measurements can be recorded at the UE at a selected rate when the UE is in a radio resource control (RRC) idle mode in a first LTE cell in a cellular network. A change in a UE state of the RRC idle mode can be identified. The Logged MDT measurements can stop being recorded at the UE when the UE state changes from a camped normally UE state to another UE state of the RRC idle mode.

  • Patent number: 9264191
    Abstract: Embodiments of an enhanced node B (eNB) and methods for network-assisted interference cancellation with reduced signaling in a 3GPP LTE network are generally described herein. In some embodiments, the number of transmission options is reduced by introducing a smaller signaling codebook. In some embodiments, higher-layer feedback from the UE to the eNodeB is established to inform the eNB about certain NA-ICS capabilities of the UE. In some embodiments, the number of signaling options is reduced by providing only certain a priori information. In some embodiments, correlations in the time and/or frequency domain are exploited for reducing the signaling message. In some embodiments, differential information is signaled in the time and/or frequency domain for reducing the signaling message.

  • Patent number: 9258747
    Abstract: Embodiments of User Equipment (UE) and methods for fast handover failure recovery in a 3GPP LTE network are generally described herein. In some embodiments, the UE may initiate handover (HO) failure recovery by transmission of a random-access channel (RACH) 2 message when both a radio-link failure (RLF) timer and a time-to trigger (TTT) timer are concurrently running. The RACH 2 message may be a message transmitted on a random-access channel for radio-resource control (RRC) connection re-establishment. The RLF timer may be activated as part of a radio-link monitoring (RLM) process based on radio-link conditions with a serving cell, and the TTT timer may have been activated as part of a HO process based on a measurement reporting event.

  • Patent number: 9258723
    Abstract: Systems, methods, and device for adjusting an operation time of a radio link failure timer are disclosed herein. User equipment (UE) may be configured to communicatively couple to an evolved Universal Terrestrial Radio Access Network (E-UTRAN). The UE use different radio link failure timer parameters depending on the speed of the UE. The radio link failure timer may run for a longer time for rapidly moving UEs and run for a shorter time for slowly moving UEs. In an embodiment, the UE may scale the radio link failure timer by a scaling factor. In another embodiment, the UE may include multiple radio link failure timers for different speeds. The radio link failure timer parameters for each speed may be specified by the E-UTRAN in a one-to-one communication. The E-UTRAN may determine which parameters to use for each UE based on characteristics of the UE.
