Abstract: Approaches provide for determining spectral information for a communications signal, such as a wideband communications signal. For example, a communications signal (e.g., a wideband signal) is received at a set of analog-to-digital converters (ADCs). The output of the ADCs is divided into a set of segments. A center frequency for each segment is determined based on the segment bandwidth and a number of segments in the set. The segments can be filtered, buffered, and analyzed using at least one digital signal processing technique (e.g., Fast Fourier Transform (FFT) technique to generate a representation of the segments in the frequency domain. Thereafter, the spectrum of frequency components (i.e., the frequency-domain representation) of the segments can be used to determine the power spectral density of the communications signal for different resolutions based on a resolution mode of the system or other criteria of the system.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for co-located Basic Service Sets (BSSs). A BSS refers to an access point (AP), wireless channel configuration, and associated stations (STAs). In one aspect, a wireless local area network (WLAN) apparatus may operate multiple virtual access points (VAPs) and multiple BSSs. The BSS may be considered co-located if they are implemented in the same physical device (such as a WLAN apparatus). Furthermore, the BSSs may be considered co-hosted if they share the same band and wireless channel, but independently signal different management frames. To aid STAs in learning about the co-located or co-hosted BSSs, the present disclosure provides techniques to advertise the co-located or co-hosted BSSs. Further improvements for co-hosted BSSs include the use of control frames that can aggregate information for more than one co-hosted BSS sharing a same wireless channel.

Abstract: Systems, methods, computer-readable medium, and apparatus are disclosed that allow for control information to be provided in an efficient manner during short burst transmission. For example, an apparatus may be configured to receive downlink control information (DCI) that indicates an allocated resource from a base station. The apparatus may also receive data from the base station. The apparatus may generate a cyclically shifted sequence that corresponds to a sequence that is cyclically shifted based on at least one of an ACK or NACK for the received data and a SR. The apparatus may then transmit the cyclically shifted sequence in the allocated resource within one symbol period of a slot of a subframe to the base station. Thus, by transmitting the SR and the ACK/NACK in one symbol, control information for short burst transmissions can be provided in a more temporally efficient manner without adding excessive complexity to the UE.
