There are provided a method and system of controlling traffic in a cellular network comprising at least one site characterized by a plurality of cells sharing a common antenna and operating in different frequencies. The method comprises processing performance-related data and network topology-related to obtain, for each cell of the plurality of cells, a performance score, thus giving rise to a set of frequency-dependent scores associated with the shared antenna; and enabling provisioning of the shared antenna in accordance with the set of frequency-dependent scores associated with the shared antenna. When no leading frequency is configured for the shared antenna, the provisioning is enabled merely when each score in the set of frequency-dependent scores meets respective adjustment criteria; and when a frequency among the different frequencies is configured as a leading frequency, the provisioning is enabled merely when a score corresponding to the leading frequency meets an adjustment criterion for the leading frequency.

Described is a method of reducing uplink inter-cell interference in a cellular communications network. The method comprises identifying in a cell any user equipments (UEs) which are susceptible to interference (ISUs) from another UE, particularly another UE in a neighboring cell. The method includes identifying in said cell any UEs causing interference (ICUs) to at least one neighboring cell and, more particularly, causing interference to a UE in a neighboring cell. The identified ISUs and ICUs are combined into a priority list for frequency resource reservation or allocation in said cell. The method may include limiting the identification of ISUs and ICUs to a selected number of UEs within the cell.

Systems and methods provide for beam detection in a wireless communication system. An apparatus for a UE may be configured to identify a plurality of CSI-RS resources corresponding to different Tx beams configured for measurement by the UE, measure an L1-RSRP for the plurality of CSI-RS resources, determine a selected Tx beam of the different Tx beams based on measured L1-RSRP values for the plurality of CSI-RS resources, and determine a measurement accuracy of a first L1-RSRP value corresponding to the selected Tx beam based on successful beam detection probability.

A mobile device determines based on a signal strength threshold when tracking devices communicatively coupled to the mobile device are lost or left behind. The mobile device communicatively couples to a tracking device and receives a first signal transmitted by the tracking device with a signal strength greater than a signal strength threshold. The mobile device receives a second signal transmitted by the tracking device and determines a measure of signal strength based on the second signal. While the mobile device is still communicatively coupled to the tracking device, and responsive to determining that the measure of signal strength of the second signal is less than the signal strength threshold, the mobile device generates a notification that the tracking device may be lost or left behind to alert the user of the mobile device.
