20130064065 | Transceiver with Automatic Detection of Unshielded Twisted Pair or Shielded Twisted Pair Cabling - Typical transceivers have multiple near-end and multiple far-end crosstalk cancellation filters. Crosstalk cancellation is one of the largest contributors to power dissipation in the DSP portion of high speed Ethernet transceivers. By detecting the cable type, a transceiver could automatically turn off its crosstalk cancellation filters when driving shielded twisted pair (STP) cables and substantially reduce the overall power dissipation in this configuration. Adaptive digital crosstalk cancellers automatically adjust the coefficients of a digital filter to match the coupling function between two channels. The impulse response of an optimal crosstalk cancellation filter can be used to determine a metric indicating the amount of coupling between the two channels. STP cables will have a much lower amount of coupling between wire-pairs than unshielded twisted pair cables. | 2013-03-14 |

In a normal mode, the signals are separated by a normal interval. When the base station enters the energy-saving mode, an interval between a first frame-structured signal and a next second frame-structured signal is increased from the normal interval to a longer energy-saving interval. The base station interrupts transmission of one or more third frame-structured signals during the energy-saving interval, and then includes the data regions of the interrupted signals in the frame of the second frame-structured signal. | 2013-03-14 |
20130064158 | Connection States for a User Entity in a Serving Gateway of an Evolved Packet Core System - A serving gateway node (SGW) and a method therefore is being provided being adapted for operating in a network in which a control-plane tunnel between a mobility manage-men! entity (MME) and a serving gateway node (SGW), a control plane tunnel between the serving gateway node (SGW) and a packet gateway node (PGW), and one or more user plane tunnels between the serving gateway node (SGW) and the packet gateway node (PGW), may be set up, the serving gateway (SGW) comprising an application layer control mechanism (APL LR CTRL), interface means, (!F) and a data base (DB). The serving gateway (SGW) is adapted for entering a state of ECM-IDLE ( | 2013-03-14 |
20130064159 | Systems and Methods for Optimizing the Distribution of Point-to-Point and Broadcast Messages in a Layered Mesh Network - Various aspects of the present invention relate to optimizing the distribution of point-to-point and broadcast messages in a layered mesh network of nodes. In one aspect, a node in the mesh network identifies a point-to-point frequency for sending a point-to-point message to a preferred node, which facilitates communication with a collector node. The node also identifies a broadcast frequency of the preferred node that is distinct from the point-to-point frequency. According to one configuration, the broadcast frequency is offset a predetermined number of frequency channels from the point-to-point frequency. In addition to listening on the broadcast frequency, the node further identifies and listens on a receive frequency for point-to-point messages from other nodes. | 2013-03-14 |
20130064160 | METHODS FOR MANAGING AT LEAST ONE BROADCAST/MULTICAST SERVICE BEARER - A central resource manager is communicatively coupled to a broadcast/multicast service (BMS) capable system. The BMS capable system has a radio access network that includes at least one BMS service area and a total number of BMS bearers for transporting media streams. Each BMS service area has associated therewith a portion of the total number of BMS bearers. The central resource manager allocates, to a first local call controller of a plurality of local call controllers, a first portion of the total number of BMS bearers to be managed locally by the first local call controller, and identifies the first portion of the total number of BMS bearer to the first local call controller. The central resource manager also manages a second portion of the total number of BMS bearers for a subsequent allocation to at least one local call controller of the plurality of local call controllers. | 2013-03-14 |
20130064161 | Group Addressing for Multicast Transmissions for Power Savings at Physical Layer - Techniques are provided to enable group addressing for multicast transmissions in a frame that is configured to support multi-user transmissions. The frame comprises a header field that is configured to indicate to recipient devices associated with a multi-user transmission interval during which time, frequency and spatial channel resources are allocated to allow for the transmission of a data frame or simultaneous transmission of corresponding ones of a plurality of data frames to respective recipient devices. In the header field, group identification information is wirelessly transmitted that indicates a group of recipient devices which are to receive a transmission during the multi-user transmission interval. Data is wirelessly transmitted for a multicast transmission during the multi-user transmission interval that follows the header field, where the multicast transmission is intended for a group of recipient devices that are members of a multicast group corresponding to group identification information contained in the header field. | 2013-03-14 |
20130064162 | Capability Extensions for Multimedia Broadcast Multicast Services - A base station of a mobile communication network supports continuity of a Multimedia Broadcast Multicast Service, MBMS, for a terminal. The base station receives, from the terminal, an information element informing the base station of a combination of bands, which the terminal supports for carrier aggregation. The terminal supports MBMS reception on any carrier configurable as a serving cell for the terminal according to the information element. The base station derives, from the received information element, MBMS reception capabilities of the terminal. The base station determines a number of carriers, which are configurable by the base station as serving cell of the terminal, such that the terminal is enabled to receive at least one MBMS. | 2013-03-14 |
20130064163 | METHOD FOR MINIMIZING COLLISIONS OF MESSAGES RESPONSIVE TO MULTI- OR BROADCAST MESSAGES IN A RADIO COMMUNICATIONS SYSTEM - A radio communication system comprises an access station that is adapted and configured to transmit a rateless encoded multicast message to a plurality of radio terminals. Each of the radio terminals transmits a reply message to the access station upon successful reception of the multicast message, wherein the transmit resources are selected from a predefined set of agreed transmit resources, where the selection is influenced by certain characteristics of the reception of the multicast message. | 2013-03-14 |
