  • Publication number: 20230239906
    Abstract: In a communication system having a plurality of user equipment (UE) devices that are operating in a contention based mode for device-to-device (D2D) communication, each UE device transmits a preferred transmission indicator when a condition for preferred transmission is met at the UE device. If a UE device receives a preferred transmission indicator, the UE device delays transmission of a D2D scheduling assignment (SA) to contend for communication resources for D2D communication. The length of the delay can be based on a number of preferred transmission indicators that are received. The preferred transmission indicator is based on a buffer size in one example.

  • Publication number: 20230239913
    Abstract: A base station (eNB) determines device-to-device (D2D) transmission parameters for signal transmission over a D2D communication link between a first user equipment (UE) device and a second UE device. The eNB instructs the first UE device to transmit a reference signal that is received by the second UE device. The second UE device reports D2D channel characteristic information indicative of the received reference signal. Based on the D2D channel characteristic information, the base station determines the D2D transmission parameters and provides the parameters to the first UE device.

  • Patent number: 11696337
    Abstract: An unmanned aerial vehicle (UAV) receives a set of Random Access preambles, determines its UAV status, and selects a Random Access preamble from the set of Random Access preambles. In some cases, the set of Random Access preambles are allocated for use by UAVs and are common to a plurality of neighboring cells. The UAV transmits the selected Random Access preamble to multiple neighboring cells. One of the neighboring cells that received the selected Random Access preamble transmits a Random Access Response to the UAV. The UAV determines which cell sent the Random Access Response, reselects to the cell that sent the Random Access Response, and transmits a Radio Resource Control (RRC) Connection Establishment Request to the reselected cell. Upon completion of a Random Access Channel (RACH) procedure, the reselected cell becomes the serving cell for the UAV.

  • Publication number: 20230208604
    Abstract: A receiving user equipment (UE) device transmits a distance-based hybrid automatic repeat request (HARQ) feedback message to a transmitting UE device based on sidelink signal quality when location information is unavailable. The receiving UE device is one of a group of UE devices receiving a groupcast data transmission from the transmitting UE device where the groupcast data transmission comprises a distance-based hybrid automatic repeat request (HARQ) feedback configuration. When location information is unavailable to the receiving UE device, the receiving UE device transmits the distance-based HARQ feedback if the signal strength of a signal received from the transmitting UE device is above a threshold and does not send the HARQ feedback if the signal quality is below the threshold. The threshold may be received from the transmitting UE device.

  • Patent number: 11683796
    Abstract: Communication equipment communicating in a licensed frequency band identifies unused unlicensed communication resources within an unlicensed frequency band. The communication equipment uses the identified unlicensed communication resources to communicate within the unlicensed frequency band. In some circumstances, the unused unlicensed communication resources are identified based on resource information received from a base station where the resource information identifies unlicensed communication resources that will be used by the base station. In other circumstances, the unused unlicensed communication resources are identified based on frequency band measurements of the unlicensed frequency band over an observation time duration longer than a sensing time duration used by unlicensed equipment using the unlicensed frequency band.

  • Patent number: 11683845
    Abstract: A communication control method used in a user equipment, a user equipment, an apparatus for controlling a user equipment, and a base station that communicates with user equipment. The user equipment performs a predetermined data transmission in which it transmits uplink user data in an RRC idle state. When the user equipment is in an RRC connected state, it transmits an RRC message to a base station indicating that the user equipment is interested to perform the predetermined data transmission after transitioning to RRC idle mode. The base station receives, from user equipment when the user equipment is in an RRC connected state, the RRC message indicating that the user equipment is interested to perform the predetermined data transmission after transitioning to RRC idle mode.
