Abstract: The present disclosure presents a method and apparatus for controlling an uplink (UL) rate of one or more use equipments (UEs) served by a base station. For example, the method may include obtaining one or more measurements of a plurality of signals from a sub-set of the one or more UEs served by the base station over a period of time. Furthermore, such an example method may include comparing the measurements to one or more respective target values to generate a power activity indicator (PAI) metric and comparing the measurements to one or more respective target values to generate a power activity indicator (PAI) metric. As such, the uplink interference in heterogeneous networks may be controlled.

Abstract: A method of wireless communication by an open radio access network-radio unit (O-RU) includes transmitting to an open radio access network-distribution unit (O-DU), a first message including antenna calibration capabilities. The O-RU receives, responsive to the first message, a second message from the O-DU. The second message includes a subscription to calibration mode switching. The O-RU dynamically adapts an antenna calibration mode to a self-calibration mode in response to a radio frequency performance metric being less than a predefined threshold value prior to expiration of a calibration timer.

Abstract: Certain aspects of the present disclosure provide techniques for interference management reference signal (RS) transmission. An example method, performed at a first network entity, generally includes applying a frequency domain function to a first copy of a first reference signal (RS) sequence to obtain a modified first copy of the first RS sequence, and outputting, to a second network entity, frequency domain samples of the modified first copy of the first RS sequence and frequency domain samples of a second copy of the first RS sequence.

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.
