Abstract: A video encoder may transform residual data by using a transform selected from a group of transforms. The transform is applied to the residual data to create a two-dimensional array of transform coefficients. A scanning mode is selected to scan the transform coefficients in the two-dimensional array into a one-dimensional array of transform coefficients. The combination of transform and scanning mode may be selected from a subset of combinations that is based on an intra-prediction mode. The scanning mode may also be selected based on the transform used to create the two-dimensional array. The transforms and/or scanning modes used may be signaled to a video decoder.

The base station determines a set of downlink transmission requirements based on the downlink compensation capability of the at least one UE, and transmits data to the at least one UE in accordance with the set of downlink transmission requirements.

Abstract: This disclosure provides methods, devices and systems for access point (AP) steering or frequency band steering based on a location of a station (STA). In some aspects, an AP may determine the location of the STA based on timing information and may steer the STA based on the location. To obtain the timing information, the AP may exchange fine timing measurement (FTM) frames with the STA. The AP may determine a distance between itself and the STA based on the timing information. The AP also may obtain distance information from other APs. Using the distance between itself and the STA, as well as the distance information from other APs, the AP may determine a location of the STA and steer the STA based on its location. The AP may steer the STA to a different frequency band of the same AP or to different AP altogether.

Each of a plurality of sensor pixels in the ultrasonic fingerprint sensor may include nine distinct ultrasonically-sensitive regions electrically coupled to a common readout circuit, where there is an ultrasonically-sensitive region of another sensor pixel disposed between each of the nine distinct ultrasonically-sensitive regions. The ultrasonic fingerprint sensor may further include circuitry for binning together groups of sensor pixels during certain lower-resolution operations such as touch sensor operations. The ultrasonic fingerprint sensor may be used in capturing fingerprint images that are then used in an authentication process.

Abstract: A base station may transmit downlink control information messages (DCIs) that schedule multiple physical downlink shared channels (PDSCHs) in a single DCI (multi-PDSCH DCIs) to a UE. The base station may generate DCIs with multiple downlink association index (DAI) bitwidths. The base station generate a given DCI with a DAI bitwidth based on a DCI format of the DCI, based on whether the DCI is a multi-PDSCH DCI, based on a carrier that the DCI is transmitted on, or whether the base station is capable of scheduling the UE with multi-PDSCH DCIs in general. The UE may determine the DAI bitwidth of received DCIs and may determine whether any DCIs were missed based on the DAI and the bitwidth of the DAI.

Abstract: This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to pilot tone designs that support distributed transmission. A transmitting device may modulate a physical layer convergence protocol (PLCP) protocol data unit (PPDU) on a number (M) of tones representing a logical RU associated with the legacy tone plan and may further map the M tones to M noncontiguous subcarrier indices associated with a wireless channel. The transmitting device may transmit the PPDU, over the wireless channel, with a number (N) of pilot tones each having a respective location relative to the M tones as mapped to the M noncontiguous subcarrier indices. In some implementations, the relative locations of the N pilot tones may be different than relative locations of a number (K) of pilot tones associated with the logical RU.

In the event of a collision in reserved resources of multiple different sources, the sources or relays may determine a priority of each communication and transmit a selected communication based on the priority determination.
