Abstract: An electronic device may include communications circuitry, sensing circuitry, and a set of antennas having first and second feeds for covering different polarizations. The communications circuitry may transmit signals with a first polarization using each of the antennas and may concurrently transmit signals with a second polarization using all but a selected one of the antennas. The sensing circuitry may concurrently transmit sensing signals with the first polarization using one of the antennas and may receive sensing signals with the second polarization using the selected antenna. The sensing signals may include chirp signals generated to include muted periods that correspond to a range of frequencies that overlap frequencies at which the wireless circuitry is subject to radio-frequency interference. This may allow for concurrent wireless communications and sensing operations without interference between the communications circuitry and the sensing circuitry.

Abstract: A wireless communication system may use federated learning to develop a global model. The system may initialize parameters of user equipment (UE) models. A network node may select multiple UEs to participate in federated training. The selected UEs may choose one or more model layers to generate local models. The network node may aggregate the local models to generate a global model. The process may be repeated until the global model converges.

Abstract: Triggering an uplink (UL) gap at a base station may include decoding a user equipment (UE) UL gap capability report received from a UE. A radio resource control (RRC) UL gap configuration for transmission to the UE may be encoded. The RRC UL gap configuration may include configuration information associated with at least one of a periodicity, offset, or length. Measurement information received from the UE may be decoded. The measurement information may include at least one of a power headroom value, a PCMAX,f,c value, or a P value. Based on the power headroom value, the PCMAX,f,c value, or the P value, the UL gap configuration may be activated by encoding a medium access control (MAC) control element (MAC CE) for transmission to the UE.

Abstract: A first device may transmit a first symbol for a second device and a second symbol for a third device. The first device may generate a first dictionary and a second dictionary that satisfy a complementary rule. The first device may modulate the first symbol onto an entry from the first dictionary to produce first modulated data and may modulate the second symbol onto an entry from the second dictionary to produce second modulated data. The first device may generate a third symbol as a joint modulation of the first and second modulated data and may transmit the third symbol using a resource element. The second device may decode the third symbol based on the first dictionary to recover the first symbol. The third device may decode the third symbol based on the second dictionary to recover the second symbol. Privacy may be maintained between the second and third devices.

Abstract: Apparatuses for FR2 UL gap configuration, and associated configuring methods. In one aspect, a dedicated radio resource control (RRC) signaling is used to configure a UL gap by transmitting. The UL gap configuration may indicate a reference cell to determine a UL gap pattern for a multi-radio dual connectivity (MR-DC) configuration. The UL gap configuration may indicate a system frame number (SFN) and a subframe of the reference cell used for calculating the UL gap pattern. The reference cell can be selected from a list of cells including FR1 cells or can be limited to FR2 cells.

Abstract: A distributed multi-antenna system includes a first access point configured to emit first beams to a user equipment device. The first access point is also configured to receive, from the user equipment device, an indication of a first beam selected from the first beams via a beam sweeping procedure. The distributed multi-antenna system also includes a second access point configured to receive, from the user equipment device or the first access point, the indication. The second access point is also configured to emit a second beam of second beams corresponding to the second access point to transmit data to the user equipment device based on the indication and a location of the second access point.

Abstract: Techniques discussed herein can facilitate enhancements to measurement for a User Equipment (UE) in Radio Resource Control (RRC) Connected mode for configuration of Carrier Aggregation (CA) and/or Dual Connectivity (DC). One example embodiment comprises a UE device comprising a processor configured to perform operations comprising: transmitting a UE Assistance Information message comprising a measurement request; receiving a first RRCReconfiguration message comprising a measConfig information element (IE); performing one or more measurements on each of on one or more frequencies based at least on the RRC measConfig IE, wherein the one or more frequencies comprise at least one non-serving frequency associated with a neighboring cell; transmitting a MeasurementReport message that indicates the one or more measurements for at least one of the one or more frequencies; and receiving a second RRCReconfiguration message that configures the UE with the at least one of the one or more frequencies.

Abstract: 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).
