摘要： A method and system are provided to perform channelization in a wireless communication network, wherein the wireless communication network including at least one base station that is communicatively coupled to at least one mobile terminal. A bandwidth of the wireless communication network is divided into a plurality of zones at the base station. Resource blocks are provided at the base station to receive data symbols transmitted in the wireless communication network. A plurality of resource blocks are combined at the base station to form a physical basic channel unit which are allocated to one of the plurality of zones at the base station. A permutation is performed on the physical basic channel unit to form a logical basic channel unit. A channel is provided to communicatively couple the base station and the mobile terminal so that the mobile terminal may send an access grant message and a user identification to the base station to transmit data in the logical basic channel unit.

摘要： One method of wireless communication involves acknowledging that an anchor base station received a handover indication signal. Another method involves: receiving, from base stations of an active set, offset signals identifying a respective differences in time between a reference time and respective times when the base station received a ranging signal from a mobile station; and transmitting, to the mobile station, a ranging control signal in response to the respective offset signals. Another method involves transmitting, to a mobile station in response to an active set signal, a system configuration information signal including system configuration information of a base station in an active set. Another method involves determining an uplink control channel power parameter in response to channel condition signals received from base stations in an active set. Another method involves transmitting a control signal to base stations in an active set on respective control channels. Apparatuses are also disclosed.

摘要： Apparatus and methods are provided for transitioning wireless devices between a plurality of states having increasing resource intensity from a least resource intensive state to a most resource intensive second state. All power-on wireless devices are ranked. A respective subset of the power-on wireless devices is assigned to each state, the power-on wireless devices of the subsets having rankings which increase with resource intensity of the state. Signalling is generated to the wireless devices to instruct them to implement any change in state. The priorities which are calculated for the purpose of state scheduling are preferably the same as those, or at least based upon the priorities used for packet scheduling.

摘要： The invention provides various schemes for negotiating communications between wireless mesh network nodes operating in accordance with the IEEE 802.11e standard. However, more generally, the invention can be operated in accordance with other communication standards.According to a broad embodiment of the invention, a method is provided in which meeting durations are divided into at least two portions, an uplink transmission portion and a downlink transmission portion. In order to protect the negotiation packets from collisions, the negotiation process is combined with the uplink and downlink data transmissions. In some aspects of the invention, the negotiation process is protected from collisions by using the transmission opportunity (TXOP) protocol that is available in the IEEE 802.11e standard. The inventive methods can be used with a contention based protocol or a contention free based protocol.According to another broad embodiment of the invention there is provided a wireless network node capable of implementing methods described for negotiating communications between neighbouring nodes.

摘要： Implementations of a registration procedure are described. The registration procedure includes a Access and Mobility Function (AMF) selection procedure and a Session Management Function (SMF) selection procedure. The AMF receives a Non-Access Stratum (NAS) registration request pertaining a User Equipment (UE). At least partially in response to the registration request: the AMF registers the UE on the network; and establishes a Protocol Data Unit (PDU) session for the UE. The AMF transmits a registration response to the UE. An access node of the network receives a Radio Resource Control (RRC) registration request from a User Equipment (UE). At least partially in response to the registration request: The access node selects an AMF, and forwards a corresponding Non-Access Stratum (NAS) registration request to the selected AMF. The NAS registration request includes PDU session request information pertaining to the UE.

摘要： An aspect of the disclosure provides a method for session admission at a node in an infrastructure provider network. The method includes receiving a connection request from a user equipment not associated with a network with which the infrastructure provider network is associated and obtaining from the user equipment, an identification of a service provider with which the infrastructure provider network is associated. Access authorization is then requested from the identified service provider. Embodiments allow such a process to provide government mandated free access, or for some other service provider to pay for the service.
