| 20090201907 | MULTI-HOP COMMUNICATIONS IN A WIRELESS NETWORK - Systems and techniques are disclosed relating to wireless communications. The systems and techniques involve wireless communications wherein a module or communications device is configured to select first and second terminal pairs, the first terminal pair having a first transmitting terminal and a first receiving terminal, and the second terminal pair having a second transmitting terminal and a second receiving terminal, schedule a first signal transmission from the first transmitting terminal to an intermediate terminal, the first signal transmission being destined for the first receiving terminal, schedule, simultaneously with the first signal transmission, a second signal transmission from the second transmitting terminal to the second receiving terminal, and schedule a power level for each of the first and second signal transmissions that satisfies a target quality parameter for each of the intermediate terminal and the second receiving terminal. | 08-13-2009 |
| 20090285116 | MULTIPLE FREQUENCY BAND OPERATION IN WIRELESS NETWORKS - Embodiments for bandwidth allocation methods, detecting interference with other systems, and/or redeploying in alternate bandwidth are described. Higher bandwidth channels may be deployed at channel boundaries ( | 11-19-2009 |
| 20090290616 | METHOD AND APPARATUS FOR DETERMINING THE SPATIAL CHANNELS IN AN SPATIAL DIVISION MULTIPLE ACCESS (SDMA)-BASED WIRELESS COMMUNICATION SYSTEM - An access point is disclosed herein that comprises a wireless network adapter configured to support a backhaul connection for a peer node to a network; a processing system configured to calculate precoding matrices that define spatial streams; and a transceiver configured to transmit data to the nodes on the spatial streams. | 11-26-2009 |
| 20100040019 | WIRELESS COMMUNICATION SYSTEMS WITH FEMTO NODES - Systems and methods for performing a handoff of an access terminal from a macro node to a femto node are disclosed. In one embodiment, the femto node is configured to transmit a predetermined signal for determining signal quality and an identifier that uniquely identifies the femto node to the access terminal. The access terminal is configured to transmit the identifier to the macro node. The femto node is identified as a hand in target based on the transmitted identifier and the macro node is configured to hand in the access terminal to the femto node. | 02-18-2010 |
| 20100040038 | WIRELESS COMMUNICATION SYSTEMS WITH FEMTO CELLS - Systems and methods of uniquely identifying communication nodes in a wireless communication system are described herein. One embodiment of the disclosure provides a wireless apparatus comprising a transceiver configured to receive a first identifier during at least one time slot. The first identifier identifies a first communication node. The apparatus further comprises a processing circuit configured to determine if the first identifier is received during a first time slot that is different from at least one pre-assigned time slot. | 02-18-2010 |
| 20100080163 | APPARATUS AND METHODS OF PROVIDING AND RECEIVING VENUE LEVEL TRANSMISSIONS AND SERVICES - A venue-cast system and method for providing and receiving venue level transmissions and services, including discovery of a venue specific transmission by receiving an overhead signal from a non-venue network, extracting information for receiving the venue specific transmission from the overhead signal, and tuning to receive the venue specific transmission based on the extracted information. The venue level transmission may be provided and received in a manner that does not prevent an access terminal from receiving a local area or wide area transmission. | 04-01-2010 |
| 20110154144 | ENHANCED BLOCK ACKNOWLEDGEMENT - Embodiments disclosed herein address the need in the art for enhanced block acknowledgement. In one embodiment, a receiver indicates a decoding delay for a maximum size aggregate frame in Block Ack negotiation, which may be used by a transmitter to determine to which Block Ack Request a Block Acknowledgement is responsive. In another embodiment, a Transmission Sequence Number (TSN) may be included in a Block Ack Request. The receiver includes the TSN in the corresponding Block Ack response. This allows the transmitter to determine which frames are “in transit.” The TSN may be used to identify blocks. In another embodiment, a TSN may be associated with one or more transmitted frames. While, the TSN is not transmitted with the Block Ack Request, the transmitter may determine which TSN corresponds with a Block Ack response in accordance with acknowledgements contained therein. Combinations of these techniques may be deployed. Various other aspects are also presented. | 06-23-2011 |
| 20110223952 | DISTRIBUTED HIERARCHICAL SCHEDULING IN AN AD HOC NETWORK - An ad hoc network with distributed hierarchical scheduling is disclosed. In one aspect, stations in a network mesh detect interfering neighbor stations and form interference lists. Stations transmit their interference lists. Scheduling stations schedule allocations for child stations in response to interference lists, received remote allocations, or a combination thereof. Coordination messages are transmitted including frame structure, allocations, and interference lists, among others. In another aspect, an ad hoc mesh network may be organized into a tree topology. In an example wireless backhaul network, this matches traffic flow. Distributed, hierarchical scheduling is provided where parents schedule communication with children while respecting already scheduled transmissions to/from interferers and to/from interferers of their respective children. Procedures to construct interference constraints for distributed, hierarchical scheduling are described, resulting in efficient scheduling and reuse in an ad hoc wireless network, without centralized scheduling. Various other aspects are also disclosed. | 09-15-2011 |
