Patent number: 11228382Abstract: Methods and devices for controlling channel occupancy measurement quality are disclosed. A wireless device is configured for carrier aggregation under operation with frame structure type 3. The wireless device is configured to obtain a channel occupancy threshold, obtain a set of received signal strength indication, RSSI, samples on a carrier frequency and obtain a quality criterion for a channel occupancy measurement.

Patent number: 11166314Abstract: 802.11ax nodes benefit from additional medium accesses through multi-user uplink provided by an AP, compared to legacy node. To restore fairness in medium access, the invention proposes to update node's EDCA parameters, in particular EDCA backoffs, using penalty values each time the node successfully transmits data to the AP over OFDMA resource units. This is to reduce the probability for the node to access anew a communication channel through conventional EDCA contention. The penalty value is preferably provided by the AP which has an overview of the system and may be adjusted based on information local to the node, for instance the amount of data transmitted or its current contention window. For instance, the penalty value is added to the current value of the EDCA backoff counters upon successful OFDMA transmission by the node.Type: GrantFiled: July 12, 2017Date of Patent: November 2, 2021Assignee: Canon Kabushiki KaishaInventors: Stéphane Baron, Patrice Nezou, Pascal Viger

Patent number: 11108590Abstract: A network mechanism for a communication network, e.g., Ethernet environment, includes a first control mechanism with an assigned first physical port and a second control mechanism with an assigned second physical port, the first and the second physical port being configured to receive and send data via a transmission medium. The network mechanism is configured such that transmitted data from the first control mechanism are coupled by an internal transmit connector of the first control mechanism via the first physical port into the transmission medium and received data at the second physical port are routed to an internal receive connector of the first control mechanism. Alternatively, received data can be routed crosswise to the other control mechanism, i.e., the control mechanism not assigned to the receiving physical port. The crosswise routing enables the formation of two independent ring-shaped communication paths of different transmit/receive directions within a single physical ring-shaped network.Type: GrantFiled: May 30, 2013Date of Patent: August 31, 2021Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Michael Armbruster, Ludger Fiege, Johannes Riedl, Thomas Schmid, Andreas Zirkler

Patent number: 11050599Abstract: Uplink synchronization may be achieved without adjusting for timing advance by using longer/larger cyclic prefix durations to compensate for differences in propagation delays, including the cell round-trip delays and environment based multipath delays. In this way, timing advance reference signaling may be omitted from the uplink transmissions. The cyclic prefix duration may be determined based on a characteristic of a base station's coverage area, such as a coverage area size or coverage area type. For example, a longer cyclic prefix length may be used when a base station has a larger coverage area than when the base station has a smaller coverage area. As another example, a different cyclic prefix length may be used for different coverage types. The method provided in this embodiment improves the capabilities of automatic driving and ADAS of electric vehicles. The method can be applied to vehicle networking, such as V2X, LTE-V, V2X, etc.Type: GrantFiled: September 22, 2017Date of Patent: June 29, 2021Assignee: Huawei Technologies Co., Ltd.Inventors: Liqing Zhang, Malte Schellmann

Patent number: 11032841Abstract: Aspects of the disclosure relate to an active set management scheme implemented by a scheduler in a multiple-input multiple-output (MIMO) network that minimizes capacity and interference issues. For example, the scheduler can initially group each base station into a separate active set. The scheduler can then analyze each active set to determine whether the active set is a good or bad based on the level of interference in and the number of MIMO transmit dimensions available in the respective active set. If the scheduler determines that an active set is a bad, the scheduler can determine a set of metrics that each represent a capacity and link quality that would result if the bad active set is combined with another active set. Based on the set of metrics, the scheduler can combine the bad active set with another active set, and repeat this process until no bad active sets remain.Type: GrantFiled: April 26, 2019Date of Patent: June 8, 2021Assignee: XCOM Labs, Inc.Inventors: Tamer Adel Kadous, Michael Mingxi Fan

Patent number: 10993141Abstract: A method and apparatus are disclosed. In an example from the perspective of a first device, the first device is configured with a second set of slot offsets by a network. The first device receives, from the network, a second Downlink Control Information (DCI) scheduling a sidelink resource.
