User equipment in close proximity may transfer data and control information. For example, the user equipment may exchange data or data sets between each other. Each user equipment can receive and transmit data using radio access technologies. A group of user equipments may include active user equipment and passive user equipment. Active user equipment connects with one or more base stations and transfers data on a wireless communication network via the base station. The active user equipment may communicate with other active user equipment and passive user equipment. Passive user equipment may not connect to any base station and/or the wireless communication network and may communicate with other passive user equipment and active user equipment (e.g., via a sidelink, peer-to-peer, or device-to-device channel).

Unified operation for user equipment groups

Formation of user equipment groups

Methods and systems for controlling uplink (UL) transmission power of a user equipment (UE) electronic device includes determining, using the UE electronic device, that a maximum power availability for a transmission between the UE and a wireless network node is not appropriate to current conditions. Based on the determination that maximum power availability is not appropriate the UE electronic device sends a request to the wireless network node to reduce power for communication with the wireless network node. Based on the request, the UE electronic device communicates at a reduced power level for communications with the wireless network node.

Dynamic power reduction requests for wireless communications

Systems and methods for user equipment group management and control

Cooperative communication for user equipment groups

Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for triggering a change in beam configuration based on UL beam conditions. The UE may detect an unsafe UL beam condition for an UL beam based, at least in part, on an MPE level being exceeded by the UL beam. In response to the detection, remedial actions that to alleviate the unsafe UL beam condition may be performed. The remedial actions may prioritize UL beam quality over DL beam quality and may include reducing a transmit power of the UL beam based on an MPR, triggering an intra-panel antenna switch to a candidate UL beam that satisfies one or more conditions for intra-panel beam switching, triggering an inter-panel antenna switch to a candidate UL beam that satisfies one or more conditions for intra-panel beam switching, and/or signaling a beam failure to a network serving the UE.

Beam management solution for MPE

A preamble of physical layer (PHY) data unit includes a first legacy portion and a first non-legacy portion that follows the first legacy portion. The first non-legacy portion includes i) a first orthogonal frequency division multiplexing (OFDM) symbol that immediately follows the first legacy portion and that is modulated using binary phase shift keying (BPSK), and ii) a second OFDM symbol that immediately follows the first OFDM symbol and that is modulated using BPSK modulation rotated by 90 degrees (Q-BPSK). The modulation of the first and second OFDM symbols indicates to a receiver device that conforms to a first communication protocol that the data unit conforms to the first communication protocol. The first OFDM symbol being modulated using BPSK modulation causes a receiver device that conforms to a second communication protocol to determine that the PHY data unit conforms to a third communication protocol.

Physical layer frame format for WLAN

An electronic device may be provided with wireless circuitry and control circuitry. The wireless circuitry may include a phased antenna array. Sensors and other circuitry in the electronic device may generate sensor data such as accelerometer data, gyroscope data, magnetometer data, location data, and spatial ranging data. The wireless circuitry may establish and maintain one or more wireless links with external devices based on the sensor data as the device moves over time. For example, the wireless circuitry may perform physical layer beam adjustments, inter-radio access technology handovers, intra-radio access technology handovers, and/or dual connectivity adjustments based on the sensor data. This may allow the device to maintain one or more wireless links without having to sweep the signal beam of the phased antenna array over its entire field of view each time the device has moved.

Electronic devices having sensor-augmented wireless link management

The present application relates to devices and components including apparatus, systems, and methods for determining a beam for communication between a user equipment and a base station. For example, angle of arrival estimates may be utilized for determining the beam for communication.

Sensor assisted beam tracking

Methods and systems include beamformed wireless communications to and from a user equipment electronic device. During operation of the user equipment electronic device, a change in slot aggregation is made. Using the aggregated slots, the user equipment electronic device and/or a wireless network utilize beam sweeps to determine a best beam pairing by repeating a shared channel in the aggregated slots with a beam sweep of multiple beams between the user equipment electronic device and the wireless network.

Beam sweeping with slot aggregation

Methods and apparatuses are disclosed for performing fast beam tracking in a wireless communication environment. A UE signals to a gNB its capabilities for intra-symbol beam sweeping. Depending on configuration, the UE can either assume that the intra-symbol beam sweeping configuration will be implemented, or will await a response from the gNB before implementing intra-symbol beam sweeping. Although this is generally carried out during initial access between the UE and the gNB, the beam sweeping configuration can be dynamically updated by either the UE or the gNB during established communication. For example, the UE can signal a desired change via its MAC CE, and the gNB can signal its change to the UE via DCI.

System and method for fast beam tracking in a cellular environment

Methods and apparatus provide for a wireless network to enable multiple-transmission reception point (multi-TRP) uplink (UL) time division multiplexed (TDMed) repetition transmission. The network may receive, from a user equipment (UE), beam measurements of downlink reference signals associated with a plurality of UL transmission beams from the UE to the multi-TRP. Based on criteria associated with the beam measurements received from the UE, the network enables the UE for the multi-TRP UL TDMed repetition transmission using the plurality of UL transmission beams. In addition, or in other scenarios, coordination is provided between the network and the UE to improve UL TDMed repetition transmissions when a UE switches between antenna panels.

Methods and apparatus for multi-TRP UL transmission

Systems and methods for using ranging signals with cellular devices. The ranging signals may utilize ranging slots and resources at least partially allocated by a cellular network. The resources may include frequencies used for uplink or downlink communications between the cellular network and the cellular devices. Alternatively, the resources may include frequencies outside of a spectrum used for communication between the cellular network and the cellular devices.
