Abstract: A system, apparatus, method, and non-transitory computer readable medium for resource sharing between at least a first radio access network (RAN) and a second RAN may include at least one base station and a resource manager corresponding to the at least one base station. The resource manager may determine whether to allocate at least one future slot of a radio frame of the common carrier as a first RAN slot or a second RAN slot based on received RAN resource utilization information corresponding to a current slot of the radio frame of the common carrier, or active connection information corresponding to active RAN connections served by the base station; generate RAN resource allocation information corresponding to the at least one future slot based on results of the determining, and transmit the RAN resource allocation information to at least one RAN scheduler corresponding to the base station.

Abstract: According to an aspect, there is provided an apparatus for the performing the following. The apparatus implements, separately for at least one downlink beam, a reinforcement learning model, where a state defines which of the plurality of uplink beams belong to a priority beam set for uplink reception corresponding to a downlink beam, an action is defined as an addition of a new uplink beam to the priority beam set, a removal of an uplink beam from the priority beam set or doing nothing and a reward is calculated based on a change in uplink signal-to-noise ratio due to an action adjusted with a cost for taking the action. The apparatus calculates iteratively at least one optimal state using at least one reinforcement learning model based on uplink signal-to-noise ratio statistics and on the plurality of optimal downlink beams for transmission to said plurality of terminal devices.

Abstract: Disclosed is a method including transmitting one or more reference signals to one or more user devices; performing preliminary sensing over a sensing area of interest based at least partly on the one or more reference signals; allocating, based at least partly on the preliminary sensing, radio resources for performing sensing with a higher resolution than a resolution of the preliminary sensing; and performing the sensing with the higher resolution over the sensing area of interest by using the allocated radio resources.

Abstract: Spatial and antenna information of a UAV is determined. Using at least the spatial and antenna information, a set of candidate transmission-reception beam pairs is determined, each pair between one of a set of one or more antenna panels in the UAV and one of multiple TRPs, wherein one or more of the multiple TRPs includes a receiver-only antenna panel that is oriented upward. Beam sweeping is configured to be performed for the set of candidate transmission-reception beam pairs. Based on results of the beam sweeping, a transmission-reception beam pair of the set of candidate transmission-reception beam pairs is selected to be used for uplink communication(s) from the UAV to a determined TRP in the determined best transmission-reception beam pair. The UAV may send the spatial and antenna information toward a wireless communication network including the multiple TRPs, and may send this periodically or based on thresholds.
