A session management function (SMF) receives, from a wireless device, a first message requesting establishment of a PDU session for a network slice associated with a service of a communication service provider (CSP). The first message comprises a single network slice selection assistance information (S-NSSAI) of the network slice and a CSP identifier (ID). The SMF sends, to the wireless device, a second message accepting the establishment of the PDU session for the network slice associated with the service of the CSP.

A method, network node and wireless device for fractional reuse of resources with flexible energy detection in unlicensed spectrum are disclosed. According to one aspect, a method in a network node includes associating each of a plurality of sets of resources within a cell with a different energy detection (ED) threshold, the resources in each set of the plurality of sets of resources being at least one of time resources and frequency resources.

Operation of a wireless network access point (AP) to communicate with a first set of one or more wireless client devices using a wireless protocol in which spatial reuse of channels is supported via at least a dynamically configurable basic service set (BSS) identifier of the wireless AP. The BSS identifier is utilized to identify overlapping BSSs (OBSSs). A first set of one or more wireless client devices communicate using a wireless protocol in which spatial reuse of channels is supported via at least a dynamically configurable BSS identifier of the wireless AP. The BSS identifier is utilized to identify OBSSs. Unauthorized network activity is detected based on the BSS identifier and a received BSS identifier associated with the received transmissions. A dynamic adjustment is made to one of the BSS identifiers of the AP or the received BSS identifier in response to detected unauthorized network activity.

A multi-carrier cellular wireless network (400) employs base stations (404) that transmit two different groups of pilot subcarriers: (1) cell-specific pilot subcarriers, which are used by a receiver to extract information unique to each individual cell (402), and (2) common pilots subcarriers, which are designed to possess a set of characteristics common to all the base stations (404) of the system. The design criteria and transmission formats of the cell-specific and common pilot subcarriers are specified to enable a receiver to perform different system functions. The methods and processes can be extended to other systems, such as those with multiple antennas in an individual sector and those where some subcarriers bear common network/system information.

A communication method, a base station, a radio communication node, and a user equipment are provided. A base station determines first resource configuration information, where the first resource configuration information is used for indicating N radio resource sets that are used when N radio communication nodes separately perform communication with a user equipment UE, and the radio resource includes a time domain resource and/or a frequency domain resource. The base station sends the first resource configuration information to the UE, where the UE communicates with a corresponding transmission point by using respective radio resource sets of transmission points, and the respective radio resource sets of the transmission points do not intersect. Therefore, a base station does not need to schedule a radio resource, thereby lowering a delay requirement on a backhaul link and eliminating interference.
