    摘要: Discontinuous reception (DRX) alignment techniques for dual-connectivity architectures are described. In one embodiment, for example, user equipment (UE) may comprise one or more radio frequency (RF) transceivers, one or more RF antennas, and logic, at least a portion of which is in hardware, the logic to receive a radio resource control (RRC) configuration information message containing a small cell RRC configuration information element (IE), the small cell RRC configuration IE to contain a small cell discontinuous reception (DRX) configuration IE comprising one or more inter-cell-coordinated small cell DRX parameters, the logic to determine a start time for a small cell DRX cycle based on at least one of the one or more inter-cell-coordinated small cell DRX parameters and initiate the small cell DRX cycle at the determined start time. Other embodiments are described and claimed.

    摘要: A method for low overhead system information acquisition (LOSIA) is disclosed. The LOSIA method includes several techniques for transmitting common channels in a next generation Radio Access Technology (xRAT). Instead of transmitting system information in a periodic, static, cell-specific, wideband manner, the transmission is triggered by user equipment in an “on demand” manner. The LOSIA method allows the network to control the overhead, bandwidth, and periodicity, as well as other characteristics. The LOSIA method employs several different techniques to trigger the information upon which the network can act, for example, by transmitting different payloads depending on the received trigger.

    摘要: Embodiments of UE and methods for measurement of Reference Signal Received Quality (RSRQ) are generally described herein. The UE may be configured to determine an RSRQ of a serving cell and an RSRQ of a target cell based on an indicated RSRQ measurement type. The measurement type may be received as part of a measurement configuration Information Element (IE) that indicates a first or second RSRQ measurement type. For the first RSRQ measurement type, the RSRQ may be determined based on a Received Signal Strength Indicator (RSSI) over common reference signals (CRS). For the second RSRQ measurement type, the RSRQ may be determined based on an RSSI that is based on a received power of one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols received at the UE.
