The clients may send conventional protocol data over a channel and, concurrently, send sensor data over an alternative channel. In some cases, client devices may exchange their protocol data, modify their own protocol data based on the exchanged data, and send the modified protocol data to the access point. This may allow the clients to adjust their grouping.Type: GrantFiled: September 9, 2020Date of Patent: September 26, 2023Assignee: Apple, Inc.Inventors: Raghuram C. Kamath, Diego C.

Patent number: 11751232Abstract: A communication management resource partitions allocated wireless bandwidth into a first portion (such as first virtual bandwidth or first bandwidth part) and a second portion (such as virtual bandwidth or second bandwidth part). The communication management resource determines wireless interference associated with transmission of first wireless communications over the different bandwidth portions such as from a wireless base station to multiple communication devices while in a first mode. Depending on the wireless interference determined during the first mode, the communication management resource controls conveyance of second wireless communications over the allocated wireless bandwidth to the multiple communication devices in a second mode. In one instance, the communication management system operates one or more communication devices in a device-to-device mode to alleviate wireless interference associated with use of the allocated wireless bandwidth.Type: GrantFiled: January 27, 2021Date of Patent: September 5, 2023Assignee: Charter Communications Operating, LLCInventors: Volkan Sevindik, Vijay K.

Patent number: 11737168Abstract: In an aspect, a slave UE and a master UE each establish an attachment to a core network of a cellular communications system. The slave UE obtains security credentials configured to encrypt and decrypt traffic between the slave UE and the core network. A D2D connection is established between the slave UE and the master UE (e.g., tethering). One or more communication functions are offloaded from the slave UE to the master UE, including at least one communication function with the core network for maintaining the attachment of the slave UE to the core network. Application-layer data is relayed to/from the slave UE over the D2D connection.

Patent number: 11736381Abstract: Embodiments described herein are directed to establishment of a cognitive heterogeneous ad hoc mesh network. Participant objects transmit notification signals to inform other participant objects in line-of-sight of their position and movement. These notification signals are used by each participant to establish an ad hoc mesh network between the recipient and the sender. The participants can also utilize echoes of the notification signals to detect and estimate the position and movement of participant or non-participant objects. Participant objects can share this positional information with one another to refine the estimated position and movement of non-participant objects or to correct errors in participant-reported positioning information. The position of each other participant and non-participant object is updated based on an individualized update rate that dynamically changes based on the distance and velocity of closure between the participant and the other participant or non-participant object.Type: GrantFiled: April 7, 2021Date of Patent: August 22, 2023Assignee: QUIXOTIC HOLDINGS, LLCInventors: Matthew David Perdew, Ryan Scott Luther
