  • Patent number: 11558851
    Abstract: A donor communication station transmits a unicast transmission comprising a plurality of device data sets where each device data set directed to each of a plurality of user equipment (UE) devices. A relay node receives the unicast transmission and retransmits the data sets in a broadcast transmission over a broadcast communication channel to the plurality of UE devices. In one example, the donor communication station encodes data for multiple user equipment (UE) devices by applying broadcast encoding to the data for each device before applying outer encoding to the data. The dual encoded data is transmitted to the relay node over a dedicated channel. The relay node applies outer decoding to the dual encoded data to retrieve the broadcast encoded data. The relay node then transmits the broadcast encoded device data in a broadcast transmission without outer encoding.

  • Patent number: 11558145
    Abstract: An origination device (e.g., a base station) receives relaying information from a signal forwarding device in a grant or a broadcast message. The relaying information can be information pertaining to channel conditions and/or quality (e.g., a Channel Quality Indicator) of a first communication link between the signal forwarding device and a destination device, and/or an encoding rate based on channel conditions associated with the first communication link. The origination device utilizes the relaying information to determine a first set of encoding parameters that correspond to channel conditions associated with the first communication link between the signal forwarding device and a destination device. The origination device encodes a first set of data according to the first set of encoding parameters and transmits the encoded first set of data to the signal forwarding device. The signal forwarding device transmits the encoded first set of data to the destination device.

  • Publication number: 20230007726
    Abstract: The methods, devices, and systems discussed herein involve a mobile wireless communication device (WCD) receiving a first discontinuous reception (DRX) cycle configuration from a network. In some examples, the first DRX cycle configuration is a U E-specific DRX cycle configuration. In other examples, the first DRX cycle configuration is a default DRX cycle configuration. The WCD also receives a second DRX cycle configuration that is different from the first DRX cycle configuration from the network. In some examples, the second DRX cycle configuration is compatible with a sidelink DRX cycle configuration of a D2D-capable device. Upon entering a first area that is near a potential safety scenario, such as an intersection, the WCD receives a signal containing an indicator. In response to receiving the signal, the WCD utilizes the second DRX cycle configuration to detect one or more device-to-device (D2D) transmissions from a D2D-capable device.

  • Patent number: 11509387
    Abstract: In response to an instruction received from a base station, a signal forwarding device applies a signal forwarding scheme selected from a plurality of signaling forwarding schemes by a scheduler. The signal forwarding scheme may be applied by the signal forwarding device to forward signals from the base station to a user equipment (UE) device and/or from the UE device to the base station. The scheduler selects the signal forwarding scheme based on channel characteristics of the channel between the signal forwarding device and the UE device and/or the channel between the signal forwarding device and the base station. Although at least some of the channel characteristics are determined by the base station, at least some of the channel characteristics can be determined by the signal forwarding device in some situations.

  • Patent number: 11425686
    Abstract: A relay node receives a data block containing multiplexed data streams intended for multiple user equipment (UE) devices being served by the relay node. The relay node extracts the data streams from the data block and allocates them each to a separate narrowband channel that is associated with a particular UE device. The relay node repeatedly transmits the narrowband channels to the UE devices in a broadcast transmission that is transmitted for a predetermined number of repetitions. Each UE device decodes their own respective narrowband channel to obtain the data stream intended for the UE device associated with a particular narrowband channel. A feedback mechanism is utilized by the relay node to determine whether to retransmit a data packet or a new data packet in subsequent broadcast transmissions.

  • Publication number: 20220264451
    Abstract: A device-specific synchronization signal (DS-SS) is transmitted by a base station within a data channel transmission to a mobile device before a paging time window for the mobile device. After a sleep state, the mobile device attempts to acquire the DS-SS without decoding a downlink control channel to obtain signal transmission information related to transmission of the page message from a base station. In addition to providing timing information for resynchronization, the DS-SS indicates the existence of a page message for the mobile device within the data channel. The mobile device returns to the sleep state in response to not detecting a DS-SS that indicates a page message. Prior to entering a sleep state, the mobile device receives transmission format information indicative of a transmission format of the DS-SS.

  • Publication number: 20220248293
    Abstract: A neighboring cell determines that uplink interference from an unmanned aerial vehicle (UAV) exceeds a first threshold at the neighboring cell. The neighboring cell transmits an uplink interference indicator to the UAV. In some examples, the UAV informs its serving cell of the uplink interference experienced by the neighboring cell. The serving cell can utilize information received from the UAV to make handover decisions or scheduling decisions for the UAV that caused the uplink interference. In other examples, the UAV can temporarily refrain from transmitting on at least some of its uplink resources or utilize different uplink resources for uplink data transmissions. In still other examples, the UAV can utilize downlink measurements to select which neighboring base station System Information Block messages should be monitored for an uplink interference indicator.

  • Publication number: 20220225313
    Abstract: The methods, devices, and systems discussed herein utilize a 2-stage Sidelink Control Information (SCI) design when a forwarding user equipment device (UE) forwards the time-frequency location of communication resources that (1) have been reserved by another UE, or (2) are available for the receiving UE to use for device-to-device (D2D) data transmissions. In some examples, the 1st and 2nd stages of the SCI are required to decode the data channel. In these examples, part of the SCI is in the 1st stage, and the remaining part is in the 2nd stage. Thus, a UE that receives the 2-stage SCI decodes the 1st stage for sensing whether the associated data channel is being used. The 2nd stage has the remaining relevant SCI required to demodulate and decode the same associated data channel.
