Abstract: A method for receiving an uplink signal in a wireless communication system, and a device therefore. The method according to one embodiment includes transmitting a control channel signal including a resource allocation (RA) field; and receiving an uplink signal. A size of the RA field is represented by an expression including RASizeA and RASizeB. RASizeA is a first number of bits required for representing a resource indication value (RIV) corresponding to a starting resource block (RB) and a length of contiguously allocated RBs within a given uplink bandwidth. RASizeB is a second number of bits required for representing a combinatorial index r corresponding to 4 indexes used to indicate a start resource block group (RBG) index and an end RBG index of a first RB set and a start RBG index and an end RBG index of a second RB set within the given uplink bandwidth.

Abstract: A base station apparatus communicates with a mobile station apparatus transmitting a data signal and a reference signal for channel estimation. The base station includes: a simultaneous transmission setting part which sets simultaneous transmission control information indicating whether or not to enable simultaneous transmission of the data signal and the reference signal, a transmission section which transmits the set simultaneous transmission control information to the mobile station apparatus; and a radio resource control section which determines whether or not to enable simultaneous transmission of the data signal and the reference signal on the basis of a power headroom which is notified from the mobile station apparatus, the headroom being a difference between the maximum transmit power value of the mobile station apparatus and a prescribed power value estimated for uplink transmission.

Abstract: The invention relates to a receiving unit in a wireless communication network comprising a processing unit being configured to generate Automatic Repeat request (ARQ) feed-back messages for acknowledgement or negative acknowledgement of received data units in a wireless communication channel. In order to avoid signalling overhead, it is proposed that said processing unit is further configured to delay the generation of Automatic Repeat request (ARQ) feedback messages until the processing unit has recognized irregularities in the data transmission or until the number (C) of delayed Automatic Repeat request (ARQ) feedback messages has reached a threshold value.

Abstract: A network switch including a set of communication ports is provided. The communication ports may have an allocated prebuffer to store data during packet switching operations. The network switch may further include a calendar associated with the set of communication ports that provides bandwidth configuration for the set of communication ports. The network switch may further include a secondary calendar that may be dynamically setup. The secondary calendar may provide an alternative bandwidth configuration strategy for the set of communication ports. The switch includes circuitry that may increase the prebuffer size and upon the successful increase of the prebuffer size reconfigure the set of communication ports from the original calendar to the secondary calendar, without a reboot. The circuitry may reset the prebuffer size after reconfiguration is complete and the switch may continue operation according to the reconfigured settings.

Abstract: Basestation equipment in a mobile data network is subject to harsh environmental conditions at many remote locations. International Business Machines Corporation (IBM) has introduced a Mobile Internet Optimization Platform (MIOP) appliance, referred herein as the MIOP@NodeB. This appliance is placed at the edge or basestation of a mobile data network to provide a platform for hosting applications and enhancing mobile network services. The introduction of an edge appliance provides a platform for additional reliability functions. A predictive failure mechanism in the basestation appliance mitigates the effects of predicted failures in a mobile network basestation due to weather conditions. The predictive failure mechanism considers historical data, ambient environmental conditions, weather alerts and weather forecasts to take pre-emptive action to avert partial or total failure of the basestation equipment.

Abstract: A method of forwarding traffic through a network node including an ingress IO card, an egress IO card, and a pair of parallel switch fabric cards. One of the switch fabric cards is designated as a working switch fabric card, and the other one of the switch fabric cards is designated as a protection switch fabric card. In the ingress IO card, the traffic flow is divided into a committed information rate (CIR) component and an extra information rate (EIR) signal. Under a normal operating condition of the node, the ingress IO card forwards the CIR traffic component through the working switch fabric card, and forwards the EIR traffic component through the protection switch fabric card. Upon detection of a failure impacting the working switch fabric card, the ingress IO card drops the EIR traffic component and forwards the CIR traffic component through the protection switch fabric card.

Abstract: Techniques are generally described related to a mobile ad-hoc network. One example method for transmitting data from a source node to a destination node in a mobile ad-hoc network may include receiving a route reply packet from a first node by a second node; identifying the route reply packet as an overheard route reply packet by the second node; adding a first routing entry in a routing table of the second node and the first routing entry being associated with the overheard route reply packet by the second node; broadcasting a routing entry added message associated with the first routing entry by the second node; receiving data transmitted from a third node and the data being transmitted by the third node responsive to the routing entry added message by the second node; and sending data received from the third node towards the destination node via an active route established based on the first routing entry in the routing table of the second node by the second node.

Abstract: A system, method, and computer readable medium that facilitate indirect routing of mobile-originated short messages for a mobile station attached with a femtocell system are provided. A convergence server uses indirect routing for delivery of a short message. The MS may elect to use a traffic or paging channel for delivery of the short message. If the MS selects the traffic channel for delivery of the message and if there is no existing traffic channel, the MS may first attempt to establish a traffic channel. If an active traffic channel is already established between the mobile station and the femtocell system, the mobile station sends the message to the femtocell system which, in turn, forwards the message to the convergence server.

A corresponding network device, computer program and computer program product are also presented.

Abstract: Disclosed is a satellite communication system that allocates bandwidth to maximize the capacity of the communication system while providing service to geographical areas having different demands. A smaller portion of the frequency spectrum can be allocated for subscriber beams that supply service to low demand areas. A larger portion of the frequency spectrum can be provided to subscriber beams that provide access to high demand areas. Allocation of bandwidth can be determined by the amount of demand in low demand areas versus the amount of demand in high demand areas. High demand gateways are physically located in low demand subscriber beams, while low demand gateways are physically located in high demand subscriber beams, which prevents interference.

Abstract: A radio communication system comprises a communication channel for the transmission of data packets from a primary station having a plurality of antennas to a secondary station having at least one antenna. The channel comprises a plurality of paths, and the primary station transmits a plurality of packets substantially simultaneously. Each of the plurality of packets is transmitted via a different subset of the plurality of paths, for example by arranging for each packet to be transmitted via a different antenna or antenna beam. The secondary station receives the plurality of data packets, determines whether each packet is received correctly and signals this determination (typically as an acknowledgement or a negative acknowledgement to the primary station for each of the plurality of packets. The signalling may be by any convenient means, for example transmitting each acknowledgement or negative acknowledgement via a different subset of available uplink paths.

Abstract: Disclosed is a method for determining whether a machine-to-machine group identifier (MGID) for identifying a multicast service flow is supported in a wireless access system that supports machine-to-machine (M2M) communication, wherein the multicast service flow is shared by a group of M2M terminals within an M2M group zone that is allocated to the terminals. The method comprises the steps of: receiving from the first base station M2M group zone information of the first base station and neighboring base stations; receiving from the second base station system information of the second base station; and determining whether the MGID that is received from the first base station is supported by the second base station by comparing the system information of the second base station and the M2M group zone information on the neighboring base stations.

Abstract: A method and apparatus for connecting multiple customer sites over a wide area network (WAN) using an overlay network is described. In one embodiment of the invention, each one of multiple customer edge (CE) routers establishes a Border Gateway Protocol (BGP) session with one or more BGP route reflectors and announces their private IP network prefixes and one or more transport IP addresses to reach that CE router. The BGP route reflector(s) reflect those IP network prefixes and the one or more transport IP addresses to reach that specific CE router to the other CE routers. The CE routers receive those reflected IP network prefixes and the corresponding transport IP address(es) to reach that CE router in which those IP network prefixes belong and register them in their corresponding routing/forwarding data structures. In this way, the CE routers learn how to reach each other.

Abstract: A system, method, and computer readable medium that facilitates delivery of mobile-terminated short message service messages to a mobile station attached with a femtocell system are provided. A convergence server deployed in a core network receives a short message for short message service delivery to a mobile station attached with a femtocell system. If there is no active traffic channel with the mobile station, or if the short message is to be delivered to the mobile station via a paging channel, the femtocell system triggers an authentication process. The convergence server constructs a short message service delivery request message, transmits the short message service delivery request message to the femtocell system, and receives one of an acknowledgement and a negative acknowledgment regarding delivery of the short message to the mobile station. The convergence server thereafter notifies the message center of the acknowledgment or negative acknowledgement received thereby.
