Abstract: A method of an IAB node may comprise: receiving an RRC message including measurement control information from a base station; transmitting RRC reconfiguration information including the measurement control information to each of a plurality of terminals; receiving a measurement report message including a measurement report generated by each of the plurality of terminals based on the measurement control information from each of the plurality of terminals; and grouping the measurement report messages received from the plurality of terminals into a grouped message report message, and transmitting the grouped measurement report message to the base station according to a grouped measurement reporting periodicity.

Abstract: A method of a terminal, according to an exemplary embodiment of the present disclosure, may include: requesting access to a mobile integrated access backhaul (IAB) based on cell search; receiving a tracking area (TA) update procedure stop request message from an Access and Mobility Management Function (AMF) of a core network; and deactivating a TA update procedure based on the TA update procedure stop request message.

Abstract: A method of an integrated access and backhaul (IAB) node may include: receiving, from a target base station, one or more user equipment (UE) context setup request messages including terminal radio resource reconfiguration information; sharing context information including the terminal radio resource reconfiguration information with a source IAB-distributed unit 1 (IAB-DU1); configuring terminal reconfiguration information using the shared context information; and transmitting one or more UE context setup response messages including the terminal reconfiguration information to the target base station in response to the one or more UE context setup request messages.

Abstract: Apparatus and methods tune analog filters that are parts of systems. When an analog filter is inserted into a system, the analog filter can be difficult to tune because of the difficulty in observing the analog filter's characteristics without being interfered by other circuits in the system. In one embodiment, analog filters are bypassed, and a response is determined. To this response, a time-invariant digital filter is applied to generate a reference response, such as an ideal response. The analog filters are then enabled and adjusted so that the difference between the response of the system and the reference response is minimized. This technique can be applied to arbitrary-order analog filters and can be used even when other circuits affect the observed filter response.

Abstract: The present invention is related to methods and apparatus that compensate for quadrature impairments of an analog quadrature modulator and/or demodulator over a relatively wide signal bandwidth. One embodiment pre-distorts baseband signals in a quadrature modulator compensation signal processor (QMCSP) to negate the quadrature impairment of an analog quadrature modulator and corrects a received baseband signal in a quadrature demodulator compensation signal processor (QDCSP) to cancel the quadrature impairment of an analog quadrature demodulator. The QMCSP and the QDCSP contain adaptive digital filter correction structures that pre-compensate and post-compensate, respectively, for the quadrature impairments introduced by the analog quadrature modulator and the analog quadrature demodulator over a relatively wide bandwidth.
