  • Publication number: 20240137915
    Abstract: A network base station can select, for each of one or more attached terminals, a respective downlink transmission mode (DTM) based at least in part on respective channel condition information (CCI). The base station can determine a subframe allocation of DTMs to subframes of a radio frame, and transmit downlink data to terminals based the subframe allocation. Additionally or alternatively, the base station can receive load information from a second base station associated with a different access network and determine the subframe allocation based on the load information. The subframe allocation can associate a specific access network with each subframe. Additionally or alternatively, the base station can send the subframe allocation to the second base station. Additionally or alternatively, the base station can determine a proportion of GBR traffic of a particular DTM, determine a reference-signal transmission rate associated with that DTM, and transmit reference signals accordingly.

  • Publication number: 20240129950
    Abstract: Methods, systems, and a non-transitory computer storage media storing computer-useable instructions are provided to ensure quality of experience (QoE) for extended reality (XR) devices over WiFi networks. A WiFi connectivity device receives a pairing request from an XR device. The pairing request contains an XR identifier that indicates one or more service needs of the XR device and identifies a priority of the XR device for data rate and bandwidth assignment. A negotiating agent, which can reside in the XR device or the WiFi connectivity device, negotiates a channel selection for the XR device. The channel selection negotiated is based on the XR identifier. After negotiation is complete, the XR device pairs with the WiFi connectivity device and receives scheduled transmissions on the negotiated channel.

  • Publication number: 20240129946
    Abstract: The disclosed technology provides a system and method for determining an uplink (UL) waveform for a mobile device to use for UL transmission in carrier aggregation or dual connectivity modes, where the UL waveform is selected to eliminate or minimize the deleterious effects of intermodulation distortion (IMD). The system identifies frequency bands scheduled for use by the mobile device for concurrent UL transmissions and for DL transmissions and determines if the combination of frequency bands can lead to high IMD. If the combination can lead to high IMD, the system can instruct the mobile device to switch to a Discrete Fourier Transform (DFT)-spread Orthogonal Frequency Division Multiplexing (OFDM) (DFT-s-OFDM) waveform for UL transmissions; if the combination would not likely lead to high IMD, the system can instruct the mobile device to switch to a Cyclic Prefix OFDM (CP-OFDM) waveform for the UL transmissions.

  • Publication number: 20240119840
    Abstract: A computer server receives messages from a computer device located in proximity to the computer server. The messages are generated by at least one vehicle and translated into IP packets using an N2 control plane interface and an N3 user plane interface implemented in the computer device. A message can include a direction of operation of a vehicle. From a mobile device, information is received describing motion of a user of the mobile device. The information includes a trajectory of the user. The mobile device and the vehicle are located at less than a threshold distance from the computer device. A potential collision is determined between the vehicle and the user based on the direction of operation of the vehicle and the trajectory of the user. An alert is sent to the mobile device indicating the potential collision.

  • Publication number: 20240119829
    Abstract: A roadside unit (RSU) receives, from a first set of on-board units (OBUs) of a first set of vehicles, messages describing events triggered by the first set of OBUs in response to basic safety messages (BSMs). Each BSM is received by a vehicle from the RSU or another vehicle over a PC5 interface. Each vehicle is operating at less than a threshold distance from the RSU. A timestamp is assigned to each event. A feature vector is extracted from the timestamped events. A machine learning model generates an update to functionality of the RSU based on the feature vector. The machine learning model is trained to update the functionality for vehicular management. The RSU is operated using the updated functionality to communicate with a second set of OBUs of a second set of vehicles for preventing vehicular collisions among the second set of vehicles.

  • Publication number: 20240121855
    Abstract: A telecommunication network associated with a wireless telecommunication provider can be configured to switch between New Radio (NR) Dual Connectivity (DC) and NR Carrier Aggregation (CA) in 5G cellular networks. According to examples, a UE is not limited to using a single mode (e.g., either NR CA or NR DC) that is initially selected for use by the UE. For example, a UE can be reconfigured during a session to switch from NR DC to NR CA when the UE moves toward mid-cell and/or a cell edge. In other examples, the UE can be reconfigured to switch from NR CA to NR DC when the UE moves closer to the cell. To determine when to switch, one or more network conditions (e.g., UE RF conditions) can be monitored. In some examples, a gNB can monitor power headroom reports (PHRs) received from the UE to determine when to switch.

  • Publication number: 20240109443
    Abstract: The present invention discloses methods and systems for scheduling and distributing power for electric vehicle chargers, through enabling and disabling a plurality of relays at a system. One of the criteria to allow an authenticated user to use an electric vehicle charger is whether there is enough electricity capacity. When the user is allowed to use a scheduled electric vehicle charger, its location is then sent to the user. Alert messages can be generated if charging does not begin within a first time limit and the cancellation of a reservation will take place if the second time limit is reached.

  • Patent number: 11936761
    Abstract: A component of a cellular communication system is configured to prioritize data packets based on packet tags that have been associated with the data packets. The packet tags may comprise an application identifier and a customer identifier, as examples. A Packet Data Convergence Protocol (PDCP) layer of a radio protocol stack receives a data packet and associated packet tags and assigns the data packet to a preferred transmission queue or a non-preferred transmission queue, based on the packet tags associated with the data packet. In order to manage queue overflows, data packets of the non-preferred transmission queue may be discarded when they have been queued for more than a predetermined length of time. Data packets of the preferred transmission queue, however, are retained regardless of how long they have been queued.

  • Patent number: 11917471
    Abstract: A telecommunication network associated with a wireless telecommunication provider can be configured to dynamically switch the primary cell (PCell) used by user equipment (UE) for carrier aggregation (CA) in 5G cellular networks. Instead of remaining anchored to an initially selected PCell, a different PCell may be dynamically selected based on different network conditions. The network conditions may include network congestion, network capacity, uplink speed, location of the UE, an activity of the UE (e.g., is the UE uploading or planning to upload data), and the like. As an example, the PCell may be selected from an n41 (2.5 GHz) cell and an n71 (600 MHz) cell. When the UE is close to the n41 cell, the n41 cell may be selected. When the UE is moving away from the cell center and toward the cell edge, the PCell may be switched from the n41 cell to the n71 cell.

  • Publication number: 20240040487
    Abstract: Spatial compute devices form an ad-hoc communication network that comprises point-to-point wireless links between the spatial compute devices. The spatial compute devices exchange application data for a user application over the ad-hoc communication network. The spatial compute devices indicate their ad-hoc communication network, user application, and application users to an application server system. A new spatial compute device detects the ad-hoc communication network and queries the application server system. The application server system responds to the new device with the application users that are currently using the user application over the ad-hoc communication network. The new device presents to a user the application users that are currently using the user application over the ad-hoc network, and in response, receives a user selection of the user application.

  • Patent number: 11889430
    Abstract: A user equipment (UE), such as a mobile phone, may support multiple power classes. Power classes can define maximum output power levels for uplink transmissions. A base station of a radio access network (RAN) can, based on metrics reported by the UE, dynamically instruct the UE to switch to using a different power class. For example, the base station may instruct the UE to switch from using a first power class with a higher maximum output power to using a second power class with a lower maximum output power, in order to preserve battery life of the UE in situations in which the second power class provides sufficient output power for uplink transmissions to reach the base station.
