Abstract: A wireless device is provided that determines a set of expected packets from a second wireless device, each expected packet of the set of expected packets comprising an expected cyclic redundancy check (CRC) of a set of expected CRCs, receives a packet from the second wireless device, the received packet comprising a header and a first CRC, determines whether a second CRC generated based on the header in the received packet matches the first CRC received in the received packet, determines, when the generated second CRC does not match the first CRC received in the received packet, a third CRC of the set of expected CRCs based on the first CRC, and replaces the received header with a header corresponding to the determined third CRC.

Abstract: Systems and methods are disclosed for compensating I-Q imbalance in a wireless receiver. The receiver may employ a quadrature downconverter configured to receive an RF signal input and output an in-phase component and a quadrature component at an IF, an IF rotation block configured to downconvert the in-phase and quadrature components to baseband and an I-Q correction block configured to compensate for an I-Q imbalance in the received signal, wherein the I-Q correction block is positioned downstream from the IF rotation block in the signal path. Performing the I-Q correction after conversion to baseband may allow the compensation calculations to operate at a reduced digital rate. Similarly, digitally adjusting the gain of the signal prior to I-Q compensation may reduce the number of bits that are manipulated during the compensation process. These features may represent significant efficiencies as compared to I-Q corrections performed at IF.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a responding device may receive a signal from an initiating device. The responding device may estimate, from the signal, a channel impulse response (CIR) that represents signal reflections from one or more objects as multiple taps. The responding device may select one or more taps, from the multiple taps, that are within a first time window that starts at a first offset from a reference point and that has a first specified time duration. The responding device may transmit, to the initiating device, a CIR report that indicates the one or more taps. Numerous other aspects are described.

Abstract: A user equipment (UE) includes a first communication component configured to use a first frequency band, such as ultra-wide band (UWB), and a second communication component configured to use an intermediate frequency (IF) band that overlaps with the UWB band, such as an IF millimeter wave (mmWave) band. The second communication component conducts an IF signal along an internal signal conduction line that may interfere with UWB processing. A processor of the UE is configured to detect an indication of such interference, and, in response to the indication of interference, control the second communication component to adjust a characteristic of the IF band signal to mitigate the interference, such as by reducing its signal strength. The amount by which the IF band signal strength is reduced may be controlled to achieve a desired tradeoff between various performance metrics, such as power consumption and quality of service.

Abstract: In some implementations, a server may send a request to a first wireless device for capability information, wherein the first wireless device is capable of transmitting both cellular and ultra-wideband (UWB) wireless signals. The server may receive a response from the first wireless device, the response comprising the capability information regarding a capability of the first wireless device for performing UWB positioning. The server may determine first UWB assistance data for the first wireless device based at least in part on (i) the capability information and (ii) information regarding one or more positioning signals transmitted in a cellular wireless network, wherein the first UWB assistance data comprises one or more parameters for a first set of one or more UWB positioning sessions between the first wireless device and a second wireless device. The server may send the first UWB assistance data from the server to the first wireless device.
