    Abstract: Various embodiments may be generally directed to techniques for configuring a secondary RF chain of a mobile device—in particular, a secondary receiver chain—to perform wireless network measurements when the secondary RF chain is not used for data communications. Various embodiments provide for a primary RF chain to provide data communications with a wireless network and for the secondary RF chain to be capable of providing aggregated data communications with the wireless network. Various embodiments provide for the mobile device to determine that the wireless network does not support carrier aggregation and to reconfigure the secondary receiver chain, which would otherwise be left unused or inactive, to perform wireless network measurements. System throughout can be improved in comparison to using the primary RF chain for performing the wireless network measurements.

    Abstract: 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.

    Abstract: A mobile terminal device includes a processing circuit and a receiver circuit. The processing circuit is configured to determine if a multimedia data stream associated with a mobile communication network is received, identify a set of reception timing occasions of the multimedia data stream, and calculate an alternate radio measurement schedule based on the set of reception timing occasions. The receiver circuit is configured to receive the multimedia data stream and perform one or more radio measurements according to the alternate radio measurement schedule if the multimedia data stream is received while the mobile terminal device is in an idle radio connection state, and perform one or more radio measurements according to a default radio measurement schedule if no multimedia data stream is received while the mobile terminal device is in the idle radio connection state.

    Abstract: A closed loop MIMO feedback system is described in which the number of available antenna ports is less than the number of antenna elements. In one implementation, sounding reference signals, received from a number of UEs, may be used, by a base station, to generate and transmit a number of OFDMA Channel State Information Reference Signals (CSI-RSs). The OFDMA CSI-RSs may be determined based on the top eigen beams associated with an average channel covariance matrix determined based on the received sounding reference signals. A UE, in response to receiving the OFDMA CSI-RSs, may determine a preferred eigen beam and transmit a quantized version of the preferred eigen beam back to the eNB. Subsequent communications with the UE may be made using beamforming techniques that are based on the quantized version of the preferred eigen beam.

    Abstract: Systems and methods are provided for handling different timing advance (TA) adjustment delays corresponding to different transmission time intervals (TTIs) from different serving cells under carrier aggregation or dual connectivity. A user equipment (UE) selects and implements one TA adjustment delay even if two or more serving cells transmit with different TTIs. In one embodiment, the UE uses a predetermined TA adjustment delay for each of a plurality of TA commands received from serving cells with different TTI lengths. In another embodiment, the UE uses a TA adjustment delay that is a maximum value of the TA adjustment delays for the TTIs from the different serving cells.

    Abstract: A new radio (NR) capable user equipment (UE) to determine whether to skip cellular measurements using s-Measure configuration based on measurements of a synchronization signal (SS) block (SSB) and/or Channel State Information Reference Signal (CSI-RS) using an s-Measure configuration. For example, an s-Measure configuration can include a reference signal received power (RSRP) value and an indicator whether to apply the value to an NR SS block or a CSI-RS. If the value meets or exceeds the measurement for the indicated signal measurement, the s-Measure is satisfied. For example, in an embodiment, the network configures a single s-Measure configuration (e.g., either an NR SS s-Measure configuration or a CSI-RS s-Measure configuration), which when satisfied the UE does not perform further measurements.

    Abstract: User equipment (UE), an enhanced NodeB (eNB) and method of improving positioning accuracy and enabling vertical domain positioning of the UE are generally described. The UE may receive a prsInfo control signal having at least one PRS configuration and subsequently a plurality of Reference Signals (RSs). The RSs may have a first Positioning Reference Signal (PRS) pattern in a first set of PRS subframes and a second PRS pattern in a second set of PRS subframes received prior to a subsequent first set of PRS subframes. The RSs may have a vertical positioning RS and a lateral positioning RS. The UE may measure PRS resource elements (REs), each having a PRS, in the first and second PRS pattern. The UE may transmit a measurement of the PRS in the first and second PRS pattern. The patterns may enable horizontal and vertical positioning to be determined.
