Abstract: Techniques, systems and apparatus are described for reducing battery power consumption during a discontinuous reception and transmission mode of operation of a communication device. When operating in the discontinuous reception and transmission mode, a communication device can process radio frequency signals received from base stations to identify a set of active base stations based on a quality of the received radio frequency signals. This can reduce the total number of base stations to decode the corresponding system frame number (SFN). Based on the decoded SFN, the communication device can select a base station to perform hand-off.
Abstract: Implementations and techniques for multicore processors having a domain interconnection network configured to associate a first collision domain network with a second collision domain network in communication are generally disclosed.
Abstract: In a method of operating a communication network (20) a time division duplex (TDD) frame (F) of information is communicated over a radio interface (32) between a wireless terminal (30) and a base station node (28). The method comprises the wireless terminal (30) receiving plural downlink (DL) subframes of the frame and, in response thereto, configuring a Physical Uplink Control Channel (PUCCH) channel to comprise up to four acknowledgements by using only two PUCCH channel resources and using PUCCH format 1a or PUCCH format 1b. In an example embodiment a PUCCH channel resource is specified by a sequence utilized for transmission of at least part of the PUCCH channel and a cyclical shift applied to the sequence. The two sequences of the respective two PUCCH resources are orthogonal, and the cyclical shift of the two PUCCH resources can be in a frequency domain, a time domain, or both the frequency domain and the time domain.

Abstract: The present disclosure discloses a method for processing a measurement task in a carrier aggregation system, which includes: deleting all measurement tasks related to a source Secondary Cell (Scell); or deleting a measurement task related to an Scell in a deleted source Scell; or doing not delete a measurement task related to the source Scell when a source Scell is reassigned to another frequency having a measurement object, and modifying a measurement object corresponding to the measurement task related to the source Scell to a measurement object of the reassigned frequency.
Abstract: A wireless communications system employs code-division multiple access information transmission techniques where the uplink and downlink transmission bandwidths are unequal. The higher bandwidth is an integer multiple of the lower bandwidth. The present system requires a base station and a subscriber unit to have two pseudo-random code generators which can be clocked separately. Alignment of the uplink and downlink pseudo-random spreading codes is achieved by truncating the code sequence for the lower speed link at the conclusion of a complete code sequence for the higher speed link.
Abstract: In a two-way ranging scheme where a first apparatus (e.g., device) determines a distance to a second apparatus (e.g., device), specified packets are sent between these apparatuses at specified times to facilitate the determination of the distance. In some aspects, these packets may be defined and/or sent in a manner that enables the apparatuses to detect a leading edge of a received packet with a high degree of accuracy. For example, an apparatus may transmit a packet a defined period of time after transmitting or receiving another packet. In addition, a packet may comprise a defined symbol sequence that is used by an apparatus that receives the packet to identify a leading edge of the packet.

Abstract: In a method for establishing S1 signaling connections in an evolved network during a handover of a UE moves from a first evolved NodeB to a second eNodeB, the first eNodeB sends to the second eNodeB information about a first S1 signaling connection parameter, which is associated with a first S1 signaling connection between the first eNodeB and a core network while the UE is in the first eNodeB. The second eNodeB allocates a second S1 signaling connection parameter associated with a second S1 signaling connection between the second eNodeB and the core network when the UE moves from the first eNodeB to the second eNodeB, and transmits the received first S1 signaling parameter and the allocated second S1 signaling parameter to the core network for establishing the second S1 signaling connection.

Abstract: Data communications are effected in a network having a plurality of different network devices, at least two of the network devices connected to a common wired network link and in which each network device is assigned to communicate during different time slots within a communication cycle. Stored communication protocol data is used to evaluate received configuration data specifying a communication schedule. An output indicative of a non-compliant communication is generated if the evaluation indicates that the communication schedule fails to comply with the protocol data. If the communication schedule complies with the stored communication protocol data, the communication schedule is stored and used to communicate data between the network devices, via a central communication circuit according to time slots specified in the evaluated communication schedule.

Abstract: A method for testing a packet data signal transceiver via its packet data signal interface. The packet data signal interface is used to convey test packet data signals from the test equipment to the DUT, and response packet data signals responsive to such test packet data signals from the DUT to the test equipment.
Abstract: In a wireless and/or power line communication (PLC) network environment, techniques for multicast of data and management of multicast groups assist in regulating bandwidth consumption and provision of desired multicast data. Nodes indicate interest in multicast groups by transmission of reports upstream. Report transmission may be suppressed to balance bandwidth with need for multicast data. Multicast data packets may be retransmitted downstream to fulfill requests indicated by the reports at a rate and/or frequency based on multicast packet duplication or redundancy. Information, such as broken links or “leave” packets, may indicate that one or more downstream nodes should be removed from a forwarding state. However such removal may impact other nodes. A query may be transmitted downstream, to determine if retransmission/forwarding of multicast retransmissions should continue. Query transmission may be based on a balance between query bandwidth consumption and the needs of downstream nodes.

Abstract: Transmission techniques are provided that improve service continuity and reduce interruptions in delivery of content that can be caused by transitions that occur when the User Equipment (UE) moves from one cell to the other, or when the delivery of content changes from a Point-to-Point (PTP) connection to a Point-to-Multipoint (PTM) connection in the same serving cell, and vice-versa. Such transmission techniques enable seamless delivery of content across cell borders and/or between different transmission schemes such as Point-to-Multipoint (PTM) and Point-to-Point (PTP). Mechanisms for adjusting different streams and for recovering content from each data block during such transitions are also provided so that data is not lost during a transition. In addition, mechanisms for realigning data during decoding at a receiving terminal are also provided.

Abstract: A network device receives, from a remote user device, a requested test that includes test Internet protocol (IP) packets, and converts the test IP packets into hardware test commands. The network device also performs, based on the hardware test commands, the requested test on a component of a network device card to produce hardware test results. The network device further converts the hardware test results into test results in an IP packet format, and provides the tests results in the IP packet format to the remote user device.
Abstract: A receiver may receive alerts from a radio-broadcast following a tone or other indication preceding each alert, for example, the National Oceanic and Atmospheric Administration's (NOAA) broadcasted weather alerts. Received alerts may be recorded and stored for future playback to an end user, and the receiver may indicate to the user that an alert has been stored, varying the type of indication according to the type of alert stored. The receiver may record alerts specific to one or more zip codes, geographic regions, Global Positioning System (GPS) coordinates, Federal Information Processes Standards (FIPS) codes, Specific Area Messaging Encoding (SAME) profiles, or other user location data. The user may then select locations and type of alerts to be replayed. Additionally, the receiver may be used in conjunction with other co-located devices to provide information to an end user through a variety of methods and devices.
Abstract: A communication system which can automatically construct a network, as well as reducing power consumption of each node in the network is provided. A child node calculates a timing of next receiving broadcast information based on timing information included in broadcast information. It then accepts input of broadcast information transmitted from a management node and transmits a registration request. It further accepts input of broadcast information transmitted from the management node and determines whether or not it is registered in the network based on slot assignment information included in the broadcast information. If the child node determines that it is registered in the network, it calculates a timing for receiving a reply request transmitted from the management node.
