Abstract: A slave node (300) is slave equipment that operates in accordance with a control frame transmitted from a master node (200). The slave node calculates a control frame statistic that is a statistic of one or more control frames transmitted from the master equipment and estimates a master environment value based on the calculated control frame statistic. The slave node measures a slave environment value. The slave node estimates a frequency deviation of a master clock based on the estimated master environment value and estimates a frequency deviation of a slave clock based on the measured slave environment value. The slave node modifies a clock value of the slave clock based on a difference between the frequency deviation of the master clock and the frequency deviation of the slave clock.

Abstract: A method and system for controlling a full-duplex communication system to operate as a time domain duplexing system with dynamic bandwidth allocation. One method includes detecting a change in conditions which necessitates an updated transmit time allocation and generating a LLDP advertisement which reflects the updated transmit time allocation. The initiating port transmits the LLDP advertisement to a link partner to notify the link partner of the updated transmit time allocation and in response, the initiating port receives a link partner LLDP advertisement from the link partner. The updated transmit time allocation is provided to a TCI client and the TCI client updates the reconciliation sublayer with updated transmit time allocation. Then implementing, using the reconciliation sublayer, transmit time allocations for a PHY layer and a MAC layer. Transmitting the data with the PHY layer occurs over a channel during transmit time allocations as defined by the reconciliation sublayer.

Abstract: Systems, apparatuses, and methods are described for wireless communications. A base station may transmit wireless device-specific downlink control information comprising HARQ feedback to a wireless device. Coordinating a plurality of HARQ feedbacks may result in complicated processing at the base station and/or a delay to schedule a HARQ feedback for the wireless device. The transmission of the downlink control information may not require HARQ feedback from a wireless device. By reducing the transmission of HARQ feedback, the channel capacity utilized for error correction transmissions can be reduced, thereby enhancing resource utilization.

Abstract: The user devices in managed networks, such as 5G and 6G networks, are required to adapt their uplink transmissions to the base station's resource grid, including the timing and frequency structure of the resource grid. Message-heavy legacy synchronization procedures can consume substantial resources. Therefore, a simpler, faster procedure is disclosed in which synchronization parameters are standardized where possible, timing signals are configured in minimal size where possible, and the user device collaborates with the base station to adjust the user device's clock setting, clock rate, timing advance (to match the base station's symbol boundaries), and Doppler correction (to match the base station's subcarrier frequency), without exchanging data messages other than very brief timing signals. Such ultra-lean synchronization procedures may enable low-complexity synchronization in future high-frequency communications.
