Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may operate by asynchronously transmitting code division multiple access (CDMA) uplink signals to a network entity. The UE may transmit the CDMA signals via an uplink channel that may be shared with orthogonal frequency multiplexing (OFDM) signaling transmitted by one or more other UEs. The UE may indicate to the network entity a capability for communicating with CDMA waveforms and may use CDMA waveforms based on transmitting the indication. The UE may also receive one or more parameters associated with using the CDMA waveforms, and may use CDMA waveforms based on the one or more parameters. The uplink channel may be a random access channel (RACH) and may support RACH transmissions, or may be a data channel and support data transmissions.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for lens design for full-duplex communication. In some aspects, a device may use a lens design that enables full-duplex operation through a lens by facilitating an avoidance or mitigation of self-interference during full-duplex operation. The lens may have a first, antenna-facing surface and a second, outward-facing surface and, to avoid or mitigate self-interference due to reflection off the lens, the first surface may have a first curvature associated with a relatively small radius. In such examples, the device may transmit wireless signaling from a transmitting element and a reflection off the lens may be dispersed or otherwise oriented away from a receiving element in accordance with a design of the first curvature. In some implementations, the lens may include an anti-reflective coating to further reduce reflection off the lens.

Abstract: A mobile wireless device may dynamically alter a downlink MIMO function by switching it on and off, or switching between different downlink MIMO configurations, such as 2×MIMO and 4×MIMO. Still further, a mobile device having greater than two antennas may dynamically select a subset of the antennas to be used to receive a MIMO transmission, and further, enable a mobile device to request a subset of antennas at a base station to be used for the MIMO transmission. This dynamic control of the MIMO mode or configuration may be achieved by using implicit signaling, by way of an enlarged code word set in CQI feedback transmissions, or by using explicit signaling, by way of E-DPCCH orders. In this way, a MIMO-capable mobile device may dynamically be configured for downlink MIMO transmissions as the conditions demand, enabling MIMO to be switched off when its use might otherwise cause performance to suffer.

Abstract: Disclosed are systems and techniques for transferring device content using radio frequency (RF) sensing. For instance, a first wireless device can identify a first user of the first wireless device based on a first radio frequency (RF) signature associated with the first user. The first wireless media device can determine a disengagement of the first user from the first wireless media device. In response to the disengagement, content information associated with usage of the first wireless device by the first user can be captured.
