A method performed by a network node (160) includes serving a cell area by a first physical network node for a first time duration. The first physical network node uses an identifier of a logical network node. For a second time duration, the cell area is served by a second physical network node. The second physical network node uses the identifier of the logical network node. The first physical network node serves the cell area with a first frequency band and the second physical network node serves the cell area with a second frequency band.

Techniques and apparatus for channel mapping in shared spectrum in the presence of higher tier users are provided. One technique includes evaluating, for different channel locations of orthogonal channel(s) within available spectrum, an amount of transmission limitation imposed to a group of devices due to incumbent protection, an amount of available bandwidth, and/or a maximum contiguous channel size. A channel location is assigned to each orthogonal channel, based on the evaluation. Another technique includes determining first channel location(s) in order to assign at least a first orthogonal channel within available spectrum. Each first orthogonal channel is associated with a group of devices sharing bandwidth within one or more networks. An exchange is participated in with a network entity to share a first set of information associated with the first channel locations. A determination is made whether to modify portion(s) of the first set of information, based on the exchange.

Systems and methods of WLAN communication including efficient spatial reuse mechanisms for relay transmissions between a repeater network and non-AP STAs in OFDMA. The non-AP STAs are grouped based on their connectivity with the individual repeaters and the radio coverage regions of the repeaters. Each group is either a non-overlapping group with the constituent non-AP STAs located in a non-overlapping coverage region of a particular repeater, or an overlapping group with the constituent non-AP STAs located in an overlapping coverage region of two or more repeaters. Based on the grouping, certain RUs (or subchannels) are reused for multiple groups without causing inter-group interference, thereby expanding the bandwidths used in the relay operations. RU allocation based on grouping can be used in combination with transmit power adjustment to achieve efficient spatial reuse in OFDMA.

Embodiments of the present disclosure provide a resource management method and apparatus for a cell cluster and a communications system. The method includes: transmitting resource allocation information by a base station taken as a cluster head of the cell cluster to other base stations in the cell cluster. By transmitting the resource allocation information by the base station taken as the cluster head of the cell cluster to the other base stations in the cell cluster, resource allocation for the cells may be performed efficiently, capabilities of coordinating inter-cell interference may be improved, and as the cell cluster may be expanded to cell clusters of a lower level or more levels, scalability of the network may be improved.

A system for allocating resources in a communications network includes a plurality of access points, where each access point in the plurality of access points is in communication with one or more user devices. The system also includes a central controller in communication with the plurality of access points. The central controller is configured to receive traffic information and channel information for access point—user device links in the communications network. The central controller is also configured to receive an intensity of independent homogeneous Poisson traffic intended for the one or more user devices. The central controller is further configured to determine a joint resource allocation based at least in part on the received traffic and channel information and the intensity of independent homogeneous Poisson traffic, where the joint resource allocation is determined with an algorithm.
