Patent number: 11871254Abstract: A base station can maintain a transmission beam toward a user device, even in changing conditions, by realtime incremental feedback in 5G and 6G. The incremental feedback is a compact one-of-three request, from the user device, indicating a higher, keep-same, or lower adjustment of a transmission parameter such as the power or beam angle. The base station then adds or subtracts a predetermined increment to that transmission parameter, thereby improving reception with each downlink message. Such incremental adjustment continues with each message to the user device, until the optimum value is reached, at which time the user device selects the keep-same choice. For efficient optimization, the base station can vary the increment size, for example escalating to larger sizes upon repeated same-sign requests, and then de-escalating to smaller increments for fine-tuning and beam optimization. Many other aspects are disclosed.Type: GrantFiled: March 28, 2023Date of Patent: January 9, 2024Assignee: ULTRALOGIC 6G, LLCInventors: David E. Newman, R. Kemp Massengill

Patent number: 8576786Abstract: A hierarchical downlink (DL) synchronization channel (SCH) is provided for wireless OFDM/OFDMA systems. The SCH includes a Primary SCH (P-SCH) for carrying PA-Preambles used for coarse timing and frequency synchronization, and a Secondary SCH (S-SCH) for carrying SA-Preambles used for cell ID detection. The total time length occupied by P-SCH and S-SCH is equal to one OFDM symbol time length of a data channel, and S-SCH is located in front of P-SCH in each DL frame. A perfect multi-period time-domain structure is created and maintained in P-SCH to increase preciseness of frame boundary estimation. With overlapping deployment of macrocells and femtocells, a predefined SCH configuration scheme is provided to separate frequency subbands used for macrocells and femtocells such that interferences in S-SCH can be mitigated. In addition, a self-organized SCH configuration scheme is provided to allow more flexibility for femtocells to avoid or introduce interference in S-SCH.Type: GrantFiled: December 30, 2009Date of Patent: November 5, 2013Assignee: MediatekInventors: Pei-Kai Liao, Yu-Hao Chang, Kuo-Ming Wu

Patent number: 8559363Abstract: A method of enabling extension of a network service of a first domain to a remote customer site hosted by an Access Gateway (AG) in a Provider Ethernet domain. In the first domain, the remote customer site is represented as being hosted by a border gateway (BG) connected to the Provider Ethernet domain, such that subscriber packets associated with the network service are forwarded to or from the remote customer site via the BG. In the Provider Ethernet domain, a trunk connection is instantiated through the Provider Ethernet domain between the host AG and the BG. A trunk cross-connection function is installed in the host AG, for transferring subscriber packets associated with the network service between a respective attachment virtual circuit (AVC) through which the remote customer site is connected to the host AG and an extended AVC tunnelled through the trunk connection.Type: GrantFiled: November 16, 2012Date of Patent: October 15, 2013Assignee: Rockstar Consortium US LPInventor: Liam Casey

Patent number: 8542641Abstract: Disclosed herein are methods and systems that may, among other possible benefits, help an access network to more quickly re-assign a forward traffic channel. An exemplary method involves an access network: (i) making a determination that a forward traffic channel is invalid, wherein the forward traffic channel is initially assigned to a first access terminal; and (ii) in response to the determination that the forward traffic channel is invalid: (a) after sending a first configuration message indicating that the forward traffic channel is invalid, waiting for at least a predetermined wait period before sending a second configuration message indicating that the forward traffic channel is valid; and (b) before the predetermined wait period has ended, making the forward traffic channel available for re-assignment to a second access terminal.Type: GrantFiled: September 13, 2010Date of Patent: September 24, 2013Assignee: Sprint Spectrum L.P.Inventor: Sachin R Vargantwar

Patent number: 8532143Abstract: A method is proposed for decoding a plurality of data packets received through a meshed communications network for the retrieval of source packets transmitted by one or more source nodes, the meshed communications network comprising relay nodes generating combined packets, each combined packet consisting of a linear combination of source packets. During the decoding by a destination node, this method consists in performing two decoding operations of which the first is a decoding by group of packets and the second is a decoding that takes account of pieces of likelihood information resulting from the first decoding. The fact of first of all carrying out a decoding with groups of packets makes it possible to exploit the repetitions (or redundancies) of packets in a meshed network to optimize the bit error rate during the decoding of source data transmitted on the communications network.Type: GrantFiled: November 5, 2010Date of Patent: September 10, 2013Assignee: Canon Kabushikia KiashaInventor: Mounir Achir
