    Abstract: An apparatus is disclosed for passive intermodulation distortion filtering. The apparatus includes a radio-frequency front-end circuit. The radio-frequency front-end circuit includes a transmit filter circuit and a receive filter circuit. The transmit filter circuit includes a passive circuit configured to combine at least two radio-frequency transmit signals associated with different transmit frequency bands. The transmit filter circuit also includes a filter coupled between the passive circuit and a first feed of an antenna. The filter is configured to attenuate frequencies associated with a receive frequency band. The receive filter circuit is coupled to a second feed of the antenna and is configured to pass the frequencies associated with the receive frequency band.

    Abstract: Positioning methods suitable for use in a wireless network that utilizes beamformed communication are disclosed. In an aspect, a range and/or granularity for reporting a reference signal timing difference (RSTD) may be configurable according to one or more beam parameters (e.g., a repetition factor, a beam shape, a frequency band, a subcarrier spacing numerology, a cyclic prefix, etc.). In another aspect, a transmitting node may transmit one or more parameters associated with a beam used to transmit a positioning reference signal (e.g., an angle of departure, a zenith of departure, a beamwidth, etc.). According to another aspect, a cyclic prefix length for a positioning reference signal that a transmitting node transmits via one or more beams may be configured to increase a number of neighbor cells visible to a receiving node.

    Abstract: Methods, systems, and devices are described for mobility robustness optimization. A network may be organized into base station clusters, and mobility information may be exchanged within the cluster. Each base station may then receive statistics based on the collected information. In some examples the cluster mobility statistics are used to generate a handover transition matrix identifying a probability of a UE remaining with a target base station within the cluster for a threshold period following a handover from a source base station that is also within the cluster. Based on the cluster mobility statistics, the base station may determine that the probability of the UE remaining with the potential target base station for the threshold period is low. The base station may then select an alternative handover target. The base station may then adjust the mobility parameters of the UE in order to direct it to the alternative handover target.

    Abstract: In one or more access points of a wireless communication network, a method for participating in a distributed clustering process directed at defining clusters of access points wherein each of the clusters comprises a cluster head and associated member nodes includes determining a marginal cost of associating an access point to each of distinct clusters of access points, based on a defined cost function, and associating the access point to one of the clusters of APs for which the marginal cost is minimized. The method may be performed by multiple access points in a peer-to-peer fashion and iterated until a stable cluster configuration is obtained. A cluster head may similarly be appointed in a distributed fashion by a current cluster head comparing total cost functions between different cluster configurations with different cluster heads.
