Abstract: Methods, systems, and devices for wireless communications and capability signaling for enhanced handover processes are described. A user equipment (UE) may transmit, to a source base station, a band combination indicator to indicate at least one band combination supported by the UE. The source base station may transmit a source base station configuration and at least one band combination supported by the UE to a target base station for use during a handover procedure. The target base station may then transmit to the source base station, a target base station configuration to use in the handover procedure. The source base station may transmit to the UE, both base station configurations to be applied during the handover procedure which may include a number of band combinations. The UE may communicate during handover execution with both base stations using at least one band combination indicated in the received base station configurations.

Abstract: Methods, systems, and devices for dynamic monitoring modes for synchronization signal block (SSB) transmissions are described. A user equipment (UE) may monitor one or more first SSB transmission opportunities for SSB transmissions from a base station and determine an SSB failure rate. Based on the failure rate, the UE may select a mode for monitoring one or more second SSB transmission opportunities. For example, if the failure rate is greater than a threshold, the UE may select a first mode for monitoring a first quantity of the one or more second SSB transmission opportunities. Additionally, if the failure rate is less than the threshold, the UE may select a second mode for monitoring a second quantity different than the first quantity of the one or more second SSB transmission opportunities. The UE may monitor the one or more second SSB transmission opportunities according to the selected mode for monitoring.

Abstract: Techniques are provided, which may be used for determining a position of a user equipment (mobile device). In certain example implementations, tones in positioning signals from one or more sources that may interfere with certain positioning signals be estimated and some form of interference mitigation may be applied, which may better enable the user equipment to acquire certain other positioning signals that may be useful in determining a position of the user equipment.

Abstract: Embodiments include methods of testing wireless devices for beam forming performance. Various aspects may include determining measurements of communication performance of the wireless device at each of a number of different angular orientations of the wireless device with respect to an antenna within a test chamber, and determining whether the wireless device satisfies beam forming performance requirements by comparing the measurements of communication performance to pass/fail criteria. Further embodiments may include a wireless device testing apparatus configured to perform testing wireless devices for beam forming performance. In some embodiments, a wireless device testing apparatus may include a test chamber, an antenna within the test chamber, a rotatable positioning system within the test chamber configured to hold a wireless device and rotate the wireless device within a range of orientations with respect to the antenna, and a computing device coupled to the antenna and the rotatable positioning system.
