  • Patent number: 11470666
    Abstract: A user equipment (UE) may experience poor communication with a network access device, and the network access device may configure the UE to connect to, and route communications through, one or more relay nodes (e.g., which may be another UE, a network operator-deployed relay, etc.). Techniques are described whereby these relay nodes may autonomously form a wireless backhaul network. Sequential implementations are considered such that the size of the wireless backhaul network may scale efficiently. In some examples, the wireless backhaul network may form by reusing existing connectivity establishment procedures. Importantly, the proposed techniques enable a relay to possess (e.g., be configured with) functionality that may traditionally be associated with a UE, base station, and gateway. Such multi-faceted functionality may enable the described sequential formation of wireless backhaul networks with tree topology.

    Abstract: This application provides a transmission method and device. The method includes: receiving, by a first device, a first RRC message sent by a second device, where the first RRC message includes first data and identification information, and then sending, by the first device, the first data and the identification information to a donor eNB of the first device by using a second RRC message. Because the first device and the second device send data by using an RRC message, network functions of the first device and the second device are simplified, and data transmission efficiency is increased after a plurality of relay nodes access an NB-IoT network.

  • Patent number: 11382091
    Abstract: A communication apparatus includes circuitry and a transmitter. The circuitry maps a precoded downlink control signal to one of a plurality of mapping candidates. The precoded downlink control signal is prepared using a first precoding for single-antenna port transmission with a single antenna port in localized allocation mode. The precoded downlink control signal is prepared using a second precoding for multi-antenna ports transmission with two antenna ports in distributed allocation mode. The plurality of mapping candidates is comprised of a plurality of aggregation levels, and one or more of the aggregation levels that is higher than a boundary among the plurality of aggregation levels is associated with only the multi-antenna ports transmission, the boundary being determined based on signaling indicated from the base station apparatus. The transmitter transmits the precoded downlink control signal.

  • Patent number: 11375364
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a broadcast transmitter, a broadcast signal including one or more multi-resolution messages. The UE may decode at least one of the one or more multi-resolution messages based on receiving the broadcast signal from the broadcast transmitter, and may determine that a data rate associated with the broadcast signal is less than a threshold based on the decoding. The UE may transmit a signal querying the broadcast reception capability of a base station based on determining the data rate. In response to the query signal, the UE may receive a signal indicating a broadcast reception capability of the base station, and may communicate, with the base station, based on the broadcast reception capability of the base station.

  • Patent number: 11368261
    Abstract: A method for transmitting consecutive messages forming a frame for a telecommunication system. The system has M sources, optionally L relays, and a destination, M?2, L?0. An orthogonal multiple-access multiple-relay channel scheme is used between the M sources and the L relays with a maximum number of M+T max time intervals per transmitted frame, including M intervals allocated during a first phase to the consecutive transmission of the M sources and T used intervals for at least one cooperative transmission allocated during a second phase to at least one node selected according to a selection strategy. T used?Tmax. The link adaptation implemented by the destination is slow and maximizes average utility metrics under constraint of an average individual BLER for each source. The utility metrics include average spectral efficiency tied to the strategy for selecting the nodes intervening during the second phase.

  • Patent number: 11363580
    Abstract: A method, apparatus, and computer program product modifying the usage of control resources for data transmission by focusing on reducing overhead of the control channel in order to maximize the spectral efficiency by configuring physical resources into two parts for an allocation into control information for the first part, and data for both the first part and the second part or data for only the second part. Data allocation in the first part based is derived based on the data allocation in the second part and the control information allocation in the first part. The number of control symbols within a subframe or transmission time interval is minimized on the downlink control signaling, used mainly for downlink and uplink grant signaling, and for the uplink HARQ ACK/NACK feedback. Where overhead is not the only problem, usage of two symbols is proposed due to the limitations of radio frequency beamforming.
