Systems and methods relating to adjusting uplink coverage in a cellular communications network are disclosed. In some embodiments, a method of operation of a network node to adjust uplink coverage for one or more cells in a cellular communications network comprises determining that there is a need to adjust uplink beam transformations for one or more cells of a plurality of cells in a cellular communications network. For each cell of the one or more cells, the uplink beam transformation for the cell is a transformation of received uplink signals for the cell from an antenna domain to a beam domain. The method further comprises, upon determining that there is a need to adjust the uplink beam transformations for the one or more cells, determining new uplink beam transformations for the one or more cells and applying the new uplink beam transformations for the one or more cells.

A device, method, and computer-readable medium are provided for detecting and mitigating signal interference due to passive intermodulation at a base station. Generally, when antennas are configured to transmit at two or more different bands or frequencies, particular combinations of frequencies can introduce passive intermodulation at one of the corresponding receive bands or frequencies. Passive intermodulation is exacerbated, in some instances, due to the presence of non-linearities in the RF path. Embodiments can be configured to automatically detect the presence of passive intermodulation in one of the receive bands or frequencies and dynamically mitigate the affected receive signal to maintain optimal system performance.

A user terminal according to one aspect of the present disclosure includes a receiving section that receives an instruction to transmit a reference signal for forming spherical coverage, and a transmitting section that transmits the reference signal, forming the spherical coverage, based on the transmission instruction. According to one aspect of the present disclosure, the formation of spherical coverage can be properly controlled.

The present disclosure provides techniques that may be applied, for example, for determining phase tracking reference signal (PT-RS) patterns/configurations. As described herein, PT-RS may be mapped to a symbol based, at least in part, on one or more symbols in which a PT-RS is expected to be punctured due to a collision with at least one of time or frequency resources allocated to another signal or to another wireless device, a MCS, and/or an expected PT-RS density.

The present application is at leasted directed to an apparatus including a non-transitory memory including instructions to perform random access in a beam sweeping network having a cell. The network includes a downlink sweeping subframe, an uplink sweeping subframe and a regular sweeping subframe. The apparatus also includes a processor operably coupled to the non-transitory memory. The processor is configured to execute the instructions of selecting an optimal downlink transmission beam transmitted by the cell during the downlink sweeping subframe. The processor is also configured to execute the instructions of determining an optimal downlink reception beam from the optimal downlink transmission beam. The processor is further configured to execute the instructions of determining a random access preamble and a physical random access channel (PRACH) resource via resource selection from the optimal downlink transmission beam.
