Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a first wireless device may receive one or more sidelink control information messages scheduling a first multi-bit feedback and indicating a number of priority field values associated with respective feedback bits of the first multi-bit feedback. In such cases, the priority of the first multi-bit feedback may correspond to the highest priority field value. The first wireless device may determine that a first set of resources allocated for the first multi-bit feedback at least partially overlaps with a second set of resources allocated for a second feedback having a second priority, and the first wireless device may select the first or second feedback to transmit or receive based on the determined priorities of the first multi-bit feedback or the second feedback.

Abstract: Apparatus and methods are presented for synchronising a slave device signal to a reference timebase, in situations where the slave device lacks knowledge of the propagation delay for signals from the reference device, e.g. if the positions of one or both of the devices are unknown or classified, or the inter-device signal propagation distance is otherwise a-priori unknown. Reference signal propagation delay is determined using an exchange of signals between the devices, with each device using a differencing procedure for eliminating effects of receiver line bias and other hardware delays. In another aspect an exchange of signals between the devices is used to detect a time residual arising from an inaccurate propagation delay estimate. The synchronisation methods can be applied to a plurality of slave devices for providing a synchronised location network. In certain embodiments signals are transmitted wirelessly, while in other embodiments they are transmitted via a fixed line.

Abstract: A user equipment (UE) transmits concurrent channel state information (CSI) processing capability information to a base station. The capability information can take various forms, and is intended to constrain the base station in the types of CSI requests that can be made to the UE. For example, the UE may indicate different CSI processing capabilities for intra-CC and inter-CC cases and/or for different codebook types. The UE may also specify supported combinations of codebook types for concurrent CSI reporting. The UE may also specify maximum resources or weighting factors for different codebook types. The UE may further restrict the rank information it provides and use a priority rule for “dropping” CSI report data due to payload size restrictions. The base station may direct, or the UE may implement, improved utilization of CSI resources that are shared for multiple concurrent CSI reports. Minimum time requirements for CSI reporting may also be relaxed.

Abstract: The present disclosure relates in general to telecommunications. In one of its aspects, the technology presented herein concerns a method, implemented in an Access Point (AP), for transmitting data intended for a terminal in a cell-free massive Multiple-Input and Multiple-Output (MIMO) communications system. The AP is grouped into a cluster together with other APs and the cluster operates autonomously. The cluster is connected to, and managed by, one Central Processing Unit (CPU). A message that the AP is selected to serve the terminal and data intended for said terminal are received from the CPU. Power control is independently conducted, exclusively considering the terminals that are served by the AP itself. Thereafter, said intended data is transmitted to the terminal.

Abstract: Systems and methods are disclosed for adjusting clock frequencies of endpoint devices in a mesh network for narrowband and ultra-narrowband communications. An endpoint device receives a reference timing signal over a wireless network from a reference device in the network. The endpoint device determines the current value of the clock frequency of the endpoint device and further determines the frequency difference between the reference frequency of the reference timing signal and the current value of the clock frequency. Based on the frequency difference, the endpoint generates a control signal and applies the control signal to the crystal oscillator of the endpoint device to adjust the frequency of the crystal oscillator. The endpoint device communicates with another device in the network using the oscillating signal generated by the adjusted crystal oscillator.

Abstract: Systems and methods are provided for optimizing resource consumption by bringing intelligence to the key allocation process for fast roaming. Specifically, embodiments of the disclosed technology use machine learning to predict which AP a wireless client device will migrate to next. In some embodiments, machine learning may also be used to select a subset of top neighbors from a neighborhood list. Thus, instead of allocating keys for each of the APs on the neighborhood list, key allocation may be limited to the predicted next AP, and the subset of top neighbors. In some embodiments, a reinforcement learning model may be used to dynamically adjust the size of the subset in order to optimize resources while satisfying variable client demand.
