Devices, systems, and methods for optimizing a mesh network by cloud computing. A cloud network controller may receive from multiple access points (APs) in a mesh network information related to channel quality based on measurements taken by the APs. Based on this information, the cloud network controller may forecast one or more optimal channels based on the information related to channel quality. The cloud network controller my then send to the multiple APs a message including a recommendation to switch to the one or more optimal channels based on the forecasting. The AP may then make a decision to carry out the recommended channel switch.

Various embodiments to enable Spectrum Access System (SAS) controlled interference management are disclosed herein. In one embodiment, an apparatus is provided. The apparatus includes a memory to store network configuration data and a processing device coupled to the memory. The processing device to generate a protection band based on interference measurements. The protection band is allocated to at least one of the infrastructure node of a Long-Term Evolution (LTE) network infrastructure. In this regard, the interference measurements are related to transmissions of data between infrastructure nodes of the LTE network infrastructure. Thereupon, a time slot is determined for the at least one of the infrastructure node based on the protection band. The time slot indicates an allocated time frame to access data in the LTE network infrastructure using a radio frequency in accordance with the protection band.

The present disclosure relates to wireless communication methods and apparatus. One example method is executed in a communications system including N cells, where at least two cells of the N cells perform wireless communication by using a same carrier set, the carrier set includes M carriers, the M carriers are divided into N time-frequency resource groups, the M time-frequency resources in a same time-frequency resource group are in a one-to-one correspondence with the M carriers, and time domain locations of time-frequency resources corresponding to a same carrier are different, N≥2, and M≥2. The example method includes determining, by a network device, a first time-frequency resource group from the N time-frequency resource groups, and performing, by the network device, wireless communication in a first cell of the N cells by using one or more time-frequency resources in the first time-frequency resource group.

Techniques are disclosed for increasing the sum spectral efficiency (SE) of cellular networks including Hybrid In Band Full Duplex (IBFD) cellular networks. These techniques include using various constraints to identify UEs that qualify to be included as part one or more frequency sharing groups. The qualification process may use, as one of the constraints, a distance between served UEs such that UEs that are too close to one another are disqualified. The UE frequency sharing groups may include at least two UEs that use the same shared frequency as an upload channel frequency one UE as the other UE uses for a downlink channel frequency. Techniques are also disclosed for the allocation of frequencies and to determine when the current groupings and/or allocated frequencies are invalid.

A domain manager (320) of a Radio Access Network, RAN, determines a configuration of a RAN resource partition of a network slice. The configuration defines which network elements of the RAN are assigned to the RAN resource partition of the network slice. The domain manager (320) receives at least one report (407, 408, 409) indicating, for at least one of the network elements assigned to the RAN resource partition, an amount of traffic of the network slice handled by the network element in an observation time window. Based on the at least one report (407, 408, 409), the domain manager (320) adapts the configuration of the RAN resource partition by removing one or more of the network elements from the RAN resource partition.
