Abstract: Methods and apparatus in a multi-carrier cellular wireless network with random access improve receiving reliability and reduce interference of uplink orthogonal frequency division multiplex (OFDM) signals of a random access, while improving the detection performance of a base station receiver by employing specifically configured ranging signals. The OFDM signals of the random access are transmitted in a at least one block indicated in configuration information. Uplink signals are transmitted with a timing adjusted based on a received time advance and a power adjusted based on a received power adjustment.

Abstract: Systems and methods are described herein to permit the adaptation of the time advance range in cellular communication systems. An exemplary method includes receiving a physical random access channel (PRACH) preamble format from a network node, deriving a timing advance (TA) range for the wireless device based on the PRACH preamble format, and transmitting a PRACH preamble sequence to the network node. Associated wireless devices and network nodes are included.

Abstract: In order to provide flexible scaling and dynamic reconfiguration, a wireless local area network controller includes a virtual dataplane with one or more virtual machines. These virtual machines pre-calculate processing parameters for packets in a data flow. For example, the pre-calculated processing parameters may include: encapsulation parameters, quality-of-service parameters and priority parameters. Subsequently, when one of the virtual machines receives a packet in the data flow on an input port, the virtual machine modifies information in a header of the packet based on one or more of the pre-calculated processing parameters and information associated with the data flow (which specifies the one or more pre-calculated processing parameters). Then, the virtual machine transmits the packet on an output port. In this way, the virtual machine maintains a fixed inter-packet time between packets in the data flow.

Abstract: A gateway is described which facilitates a change of communication cell for a mobile device in a communication system, which includes a core network. The gateway receives messages from a base station operating a cell and forwards the messages received from the base station to the core network. The gateway intercepts a message relating to a change of communication cell, from a source cell in which the mobile communication device is located to a target cell, to determine if the core network needs to be notified of the change of cell. When it is determined that the core network needs to be notified, the gateway generates a message for providing information relating to the change of cell to the core network and transmits the message to the core network.
