  • Patent number: 10644925
    Abstract: A transmission scheme for transmitting control data segments over a control channel using multi-layer or hierarchical modulation is disclosed. According to principles described herein, first and second control data segments are modulated to form multi-layer symbols configured such that the first control data segment is recoverable via demodulation at a lower order while a second control data segment is recoverable via demodulation at a higher order. In at least some embodiments, the scheme dynamically adapts this higher order to current channel conditions so as to maximize the control channel's spectral efficiency, while at the same time still allowing the system to statically fix the modulation order for the first control data segment, e.g., to maintain (blind) decoding complexity. By transmitting control data in segments using multi-layer modulation, spectral efficiency of the control channel may be improved.

  • Patent number: 10575363
    Abstract: Systems and methods relating to an unacknowledged connection release in a cellular communications network are disclosed. In some embodiments, a method of operation of a base station in a cellular communications network comprises sending a connection release message to a wireless device that is in an Out-of-Sync (OOS) state and releasing a connection with the wireless device without receiving, from the wireless device, an acknowledgement of receipt of the connection release message. In this manner, signaling overhead for releasing the connection of the wireless device that is in OOS state is substantially reduced.

  • Publication number: 20190335528
    Abstract: Embodiments of the present disclosure are related to achieving better tradeoffs between battery saving and latency to, e.g., support ultra-low latency applications by introducing soft Discontinuous Reception (DRX). In some embodiments, a method of operation of a wireless device in a wireless communications network comprises monitoring, during a DRX awake period, two or more control channel subsets during two or more time periods within the DRX awake period, respectively. The two or more control channel subsets are different subsets of a plurality of candidate control channels. In some embodiments, the two or more time periods are two or more subframes. The candidate control channels are control channels that the wireless device is configured to monitor. The two or more control channel subsets can be selected to, e.g., reduce latency while not increasing energy consumption as compared to legacy DRX.

  • Patent number: 9877325
    Abstract: A system and method for joint scheduling in a dual-carrier fixed wireless backhaul network is disclosed, wherein the primary carrier is a licensed band, and the secondary carrier is a lower cost shared band or an unlicensed band. The network comprises a plurality of Hub modules, each serving a cluster of one or more Remote backhaul modules (RBMs). A special frame structure and a control channel on the primary carrier carries control signalling messages for RBMs assigned to either the primary or secondary carrier. RBMs with a performance metric, such a spectral efficiency, above a threshold are assigned to the primary carrier. Other RBMs are assigned the secondary carrier, and a channel assignment is then performed. A transmission mode is determined based on instantaneous channel conditions, to optimize overall system performance across a network neighborhood and meet RBM quality of service requirements. A centralized server/processing unit co-ordinates dual carrier joint scheduling functions.

  • Patent number: 9369925
    Abstract: Embodiments are provided for scheduling resources considering data rate-efficiency and fairness trade-off. A value of Jain's fairness index (JFI) is determined for transmitting a service to a plurality of users, and accordingly a sum of throughputs is maximized for transmitting the service to the users. Alternatively, a sum of throughputs is determined first and accordingly the JFI is maximized. Maximizing the sum of throughputs or JFI includes selecting a suitable value for a tuning parameter in an efficiency and fairness trade-off relation model. In accordance with the values of sum of throughputs and JFI, a plurality of resources are allocated for transmitting the service to the users. For static or quasi-static channels, the relation model is a convex function with a monotonic trade-off property. For ergodic time varying channels, the tuning parameter is selected by solving the relation model using a gradient-based approach.

  • Patent number: 9338672
    Abstract: Systems and methods are disclosed for coordinating hub-beam selection in wireless backhaul networks and optionally, for joint hub-beam selection and slot assignment. Data indicative of path loss is measured or estimated for each of a set of RBMs and for each hub-beam of a respective multi-beam serving hub. A performance metric is computed, and hub-beam selection is made based on optimizing the performance metric across the set of RBMs. A serving hub may use reserved frames to train an RBM on each hub-beam and communicate beam selections, e.g. based on minimizing path loss on a per-cell or per-sector basis, or maximizing a sum-utility function for improved performance over a neighborhood of the network. A beam assignment map may be shared amongst serving hubs. A weight table of good and bad beam combinations may be generated to evaluate the cost of a hub-beam combination, for joint hub-beam selection and slot assignment.
