| 20140126556 | Signalling Arrangement for Inter-Site Carrier Aggregation Having Only Single Component Carrier Available in Uplink Direction - An apparatus is described which is connectable to a first network node by a first downlink component carrier and to at least a second network node by a at least second downlink component carrier, wherein the apparatus provides a single uplink connection. The uplink connection is shared among a first uplink component carrier to the first network node and at least a second up link component carrier to the at least second network node. Sharing of the uplink connection may be performed in a time divisional multiplexed manner. Furthermore, a corresponding method is described. | 2014-05-08 |
| 20140126557 | RADIO TRANSMISSION/RADIO RECEPTION DEVICE AND METHOD FOR COMMUNICATION WITHIN A, IN PARTICULAR WIRELESS, MOTOR VEHICLE COMMUNICATION SYSTEM INTERACTING IN AD-HOC FASHION - The invention relates to a radio transmission/radio reception device and to a method for communication within a, in particular wireless, motor vehicle communication system interacting in ad-hoc fashion which are configured such that the radio transmission/radio reception device emits a piece of information about the scope of envisaged reports, at least one further radio transmission/radio reception device receives the information, and the further radio transmission/radio reception device takes the received information as a basis for stipulating a frequency for the emission of chronologically successive reports. | 2014-05-08 |
| 20140126558 | SCHEDULING METHOD AND DEVICE HAVING CONTINUITY IN A WIRELESS PERSONAL AREA COMMUNICATION NETWORK - The present description discloses a method for a first device to transmit data in a WPAN (wireless personal area network), comprising the steps of: transmitting, to a second device, a message requesting a transmission bandwidth for transceiving non-competitive data of a first device; receiving, from the second device, transmission bandwidth allocation information corresponding to the message requesting the transmission bandwidth; and transceiving data to/from the second device according to the transmission bandwidth allocation information, wherein the transmission bandwidth allocation information may include length, gap, and window information on the transmission bandwidth for non-competitive transception. | 2014-05-08 |
| 20140126559 | IN-PLACE A-MSDU AGGREGATION FOR WIRELESS SYSTEMS - A sub-frame is generated for each MSDU to be aggregated in an A-MSDU and the sub-frame is stored in place in memory. For each sub-frame, an MSDU descriptor identifying the memory location of the sub-frame is stored in a queue. When a transmit opportunity for an MPDU arises, a DMA engine sequentially transfers the components of sub-frames stored in memory to a PHY layer using a list or other sequence of DMA descriptors obtained from at least a subset of the MSDU descriptors. Thus, these MSDU descriptors allow the aggregation of A-MSDUs to be initiated while the MSDUs are in place in the same memory in which they were initially stored. | 2014-05-08 |
| 20140126560 | SYSTEMS AND METHODS FOR ROUTING HOME AREA NETWORK (HAN) MESSAGES - Embodiments of the disclosure can provide systems and methods for routing home area network (HAN) messages. In one embodiment, a system can be provided. The system can include at least one memory that stores computer-executable instructions; at least one processor configured to access the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions. The computer-executable instructions can receive, by the at least one processor, an instruction for a HAN gateway; send the instruction to a transmission agent for routing to the HAN gateway; and transmit, by the transmission agent, the instruction to the HAN gateway. | 2014-05-08 |
| 20140126561 | WORK GROUP BRIDGE NOMADIC ROAMING - In an example embodiment, an 802.11 or Ethernet work-group local area network (WG-LAN) is assigned a global name. The WG-LAN name is bound to a local virtual local area network identifier (VLAN-ID) in parent access points (APs). A path update protocol is employed to synchronize the WG-LAN/VLAN-ID bindings in a work-group bridge with the bindings of its' parent AP. | 2014-05-08 |
