    Abstract: An arrangement configured to be employed within a user equipment (UE). The arrangement includes control circuitry. The control circuitry is configured to obtain a measurement configuration, where the measurement configuration complies with license assisted access (LAA) and includes a measurement window; obtain one or more discovery reference signals (DRS) from an evolved Node B (eNodeB) during the measurement window; determine SINR estimates based on the one or more DRS, compare the SINR estimates to a threshold; generate a target cell measurement based on the one or more DRS, the SINR estimates and the measurement configuration; and generate a measurement report that includes the target cell measurement.

    Abstract: A method of Automatic Gain Control (AGC) gain adjustment by a wireless device, including receiving a reference signal and data from a secondary cell operating in unlicensed spectrum; and adjusting the AGC gain for the secondary cell based on the reference signal, which is received in a same measurement timing configuration period as the data. Further, a method of AGC gain adjustment including receiving a primary reference signal from a primary cell operating in licensed spectrum; and adjusting the AGC gain for a secondary cell operating in unlicensed spectrum based on the primary reference signal and at least one of a transmission power difference, a reception power difference, and a propagation path loss difference between the primary cell and the secondary cell.

    Abstract: User equipment performs autonomous time adjustment that includes selecting a Timing Error Limit (i.e. Te_NR) and Maximum Autonomous Time Adjustment Step (i.e. Tq_NR) based on bandwidth (BW) and subcarrier spacing (SCS). In one embodiment, given a certain downlink BW, if the SCS=x(kHz) and the Te_NR of this SCS is N, then the Te_NR of SCS=x/2(kHz) is 2*N. Given a certain downlink BW, if the SCS=x(kHz) and the Te_NR of this SCS is N, then the Te_NR of SCS=2*x(kHz) is N/2. For example, given BW=10 MHz, if the Te_NR of SCS=30k Hz is n*Ts_NR (TS_NR is the basic timing unit for NR system), then the Te_NR of SCS=60 kHz is N/2*Ts_NR, and the Te_NR of SCS=15 kHz is 2*N*Ts_NR.
