Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may establish a wireless connection with a primary cell and may identify a set of antenna modules of the UE and multiple sets of receive beams. Each set of receive beams may include at least one beam from each antenna module. The UE may perform a measurement procedure on signals received from one or more candidate secondary cells using at least a first set of receive beams. The UE may then transmit, to the primary cell, a measurement report based on performing the measurement procedure upon determining that at least one of the multiple sets of receive beams satisfies a threshold value and before performing the measurement procedure on signals received from the one or more candidate secondary cells using at least one remaining set of receive beams.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may measure a beam, according to a measurement configuration, to determine a channel condition value of the beam, modify the channel condition value based at least in part on at least one of one or more beam characterizations, a derivation of a beamforming gain value, or an estimation of the beamforming gain value, and transmit, to a base station, a measurement report indicating the modified channel condition value. Numerous other aspects are provided.

Abstract: Described features are directed to staggered frequency channel changing for cells of spectrum sharing networks. In some examples users communicating on one or more frequency channels of a spectrum sharing network may receive an indication that those channels are to be vacated, for example that the frequency channels are not to be transmitted on, or otherwise used for communications. Cells of the spectrum sharing network may receive the indication and perform staggered (e.g., sequential or randomly-timed) channel changes. The staggered channel changes may facilitate handover of user devices of the spectrum sharing network by, for example, reducing a number of cells that are simultaneously undergoing a channel change procedure. Thus, staggered frequency channel changing may reduce user service interruptions and radio link failures in a spectrum sharing network.

Abstract: Methods and apparatus are disclosed for interference mitigation of an open-access node. The method includes determining, at the open-access node, whether uplink interference from a mobile entity is above a threshold. The method includes adjusting a transmission power to trigger a hand-in of the mobile entity in response to determining the uplink interference is above the threshold. The method includes handing-in the mobile entity from a first cell in response to adjusting the transmission power. The method includes redirecting the mobile entity to a second cell different from the first cell.

Abstract: Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a total received signal strength from transmitting nodes at the receiver. Transmit power may be defined for an access node (e.g., a femto node) such that a corresponding outage created in a cell (e.g., a macro cell) is limited while still providing an acceptable level of coverage for access terminals associated with the access node. An access node may autonomously adjust its transmit power based on channel measurement and a defined coverage hole to mitigate interference and perform a self-calibration process.

Abstract: Methods, apparatuses, and computer program products are disclosed for facilitating a beacon-assisted handover from a macro network to a femto cell during an active call. A femto cell management system assigns a unique identifier to a femto cell, which the femto cell utilizes to broadcast a beacon at a frequency different than the operating frequency of the femto cell. A wireless terminal receives a control message from the macro network directing the wireless terminal to scan particular frequencies. The wireless terminal subsequently provides a report to the macro network identifying attributes ascertained from the scan, which includes attributes associated with the beacon. The macro network then performs a handover from the macro network to the femto cell as a function of the attributes.
