A network node is configured with a common preamble format for a shared spectrum comprising a first Radio Access Technology (RAT) and a second RAT. The RACH procedure is common for the first and second RAT. The network node configures the network node with a common preamble location in time and frequency for the first and second RAT. The network node configures the UE with a preamble group comprising a number of preambles distributed between the first and second RAT for the common preamble format. When receiving from the UE, a first RACH message comprising a first preamble at the common preamble location according to the UE configuring, the network node decides whether the first RAT, the second RAT, or both the first and second RAT, shall be used for a second RACH message to be sent to the UE.

Network node and method for processing preambles in a random access channel

Embodiments herein relate to a method performed by a network node (), for handling baseband resources in a wireless communications network (). The network node () estimates an uplink resource need f( . . . ) and a downlink resource need g( . . . ) for a future Transmission Time Interval i based on resource metrics from one or more previous Transmission Time Intervals. The network node () determines a resource division between uplink and downlink based on the estimated uplink and downlink resource needs. The network node () further schedules the uplink and downlink resources based on the determined resource division.

Network node and method performed therein for handling baseband resources

To perform wireless communication scheduling, a network node () calculates a corresponding layer limit for each of a plurality of scheduling intervals of a cell () served to a plurality of user equipment via multi-user multiple-input multiple-output (MU-MIMO). The network node () schedules time-frequency resource utilization such that, for each of the scheduling intervals, no time-frequency resource is scheduled for use by more of the UEs () than the layer limit corresponding to the scheduling interval.
