E-UTRA is the air interface of 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) upgrade path for mobile networks. It is an acronym for Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access, also referred to as the 3GPP work item on the Long Term Evolution (LTE) also known as the Evolved Universal Terrestrial Radio Access (E-UTRA) in early drafts of the 3GPP LTE specification. E-UTRAN is the initialism of Evolved UMTS Terrestrial Radio Access Network and is the combination of E-UTRA, user equipment (UE), and E-UTRAN Node B or Evolved Node B (EnodeB).

System and method for satellite-long term evolution (s-lte) air interface
InactiveUS20100068993A1Facilitates broadband high-speed dataRadio transmissionDifferentiatorAir interface
An air interface for use with a mobile satellite system that extends the baseline LTE interface modulation and coding from 3GPP. The LTE OFDM and S-FDMA technologies are used in the lowest FDD E-UTRA assigned bandwidth of 1.4 MHz but can be extended up to 7 other bands. The key differentiator for S-LTE from LTE would be the use of 32-ary Amplitude Phase Shift Keying (32-APSK) in the uplink channel for S-FDMA with LDPC and turbo coding and 64-QAM in the downlink channel for OFDM with LDPC and turbo coding. This new mechanism for S-LTE with new combination of coding will allow a robust channel model for S-LTE air interface and will enable the S-LTE air interface to have an efficient link budget. The S-LTE air interface of the present invention can be implemented in 700 MHz, 1.5 GHz, 2.1 GHz and 2.6 GHz bands or any future bands allocated for the specific air interface.

Gap scheduling method based on minimum gap patterns in long term evolution system
InactiveUS20080085710A1Preventing overload of the n/wEffective latencyConnection managementRadio/inductive link selection arrangementsInter layerCell lists
The method herein concerns Long Term Evolution (LTE) whereby the measurement Gap Scheduling is decided between the UE and the E-UTRA network. The measurement Gap Scheduling will be required whenever the UE is measuring an Inter Layer LTE cell or an Inter RAT cell. The minimum Gap pattern based system depends on the priority cell list. Accordingly, the UE chooses a minimum gap pattern and indicates the same to the network, when the UE is required a gap pattern. The network takes the UE recommendation and approves the same or suggests a proper Gap Mode. Also disclosed is the use of Blind Handovers in the LTE system. This is based on a Cell Priority list. The most prioritized cell is chosen for Blind HO, in order to improve the overall cell load / schedule condition.

Combined open loop/closed loop (CQI-based) uplink transmit power control with interference mitigation for E-UTRA
A combined open loop and closed loop (channel quality indicator (CQI)-based) transmit power control (TPC) scheme with interference mitigation for a long term evolution (LTE) wireless transmit / receive unit (WTRU) is disclosed. The transmit power of the WTRU is derived based on a target signal-to-interference noise ratio (SINR) and a pathloss value. The pathloss value pertains to the downlink signal from a serving evolved Node-B (eNodeB) and includes shadowing. An interference and noise value of the serving eNodeB is included in the transmit power derivation, along with an offset constant value to adjust for downlink (DL) reference signal power and actual transmit power. A weighting factor is also used based on the availability of CQI feedback.

Radio Bearer Dependent Forwarding For Handover
ActiveUS20090042573A1Reduces X interface trafficReduce decreaseWireless commuication servicesWireless communicationTraffic capacityReal-time data
This invention employs an inherent tradeoff in a radio bearer dependent data handling method for intra-E-UTRA handoffs. For user equipment using real time data, the source node forwards to the target node not yet acknowledged real time service data units and disconnects. This makes the handoff latency short at the expense of data traffic between nodes. For user equipment not needing real time data, the source node continues to receive user equipment acknowledgements during a time out period and only forwards service data units acknowledged during the time out period. This reduces X2 interface traffic between the source and target nodes but extends the handoff latency.

In another novel aspect, a small cell in a low load condition requests measurement reports from multiple UEs. Multiple UEs reply with a measurement report request message, which contains the detected neighbor ID and the traffic load of the UE. The low-load small cell contains information obtained from the measurement report in the shutdown request message. In another novel aspect, the small cell broadcasts an open request message.
