Abstract: Aspects relate to measuring downlink beam quality in the presence of self-interference when operating in a full duplex mode configured for concurrent transmission and reception within an overlapping bandwidth. A user equipment (UE) may communicate with a base station over one or more of a plurality of uplink beams and downlink beams. For each uplink beam, the UE may obtain beam quality measurements associated with each of the downlink beams to identify a set of usable downlink beams. The UE may further transmit a report to the base station indicating the set of usable downlink beams for at least one uplink beam.

Abstract: A method at a scheduling entity might include determining that interference is present from a neighboring scheduling entity, which implements a second subcarrier spacing that is different from a first subcarrier spacing of the scheduling entity. The scheduling entity might request the neighboring scheduling entity to negotiate a bandwidth group (BWG), where the BWG is a bandwidth occupied by downlink subcarriers within which a transmission parameter is maintained. The method might include negotiating a bandwidth of the bandwidth group and transmitting, if negotiating is successful, downlink data to a scheduled entity served by the scheduling entity according to the negotiated bandwidth. The transmission parameter might be a precoder, rank, modulation order, power inside each BWG, or numerology. The numerology might be scalable and might be a combination of subcarrier spacing and cyclic prefix (CP) overhead. The subcarrier spacing might be scaled while keeping constant the CP overhead as a percentage of a symbol duration.

Abstract: Certain aspects of the present disclosure generally relate to techniques for selecting a base graph to be used for wireless communications. Selection can be based on a variety of factors. Abase graph can be used to derive a low-density parity-check (LDPC) code used for encoding a retransmission of an original transmission. An exemplary method generally includes selecting, based on a modulation and coding scheme (MCS) and a resource allocation (RA) for transmitting a codeword, a base graph (BG), from which to derive a low density parity check (LDPC) code for use in encoding data bits in the codeword (e.g., encoding data bits of a bitstream such that some redundant bits are included in the codeword), encoding the data bits to generate the codeword using the LDPC code derived from the selected BG, and transmitting the codeword using the MCS via resources of the RA.

Abstract: An apparatus and method of wireless communications includes transmitting, by a user equipment (UE), a mid-amble position indication and/or a UE capability information, wherein at least one of the mid-amble position indication or the UE capability information facilitate identification of a mid-amble position within a slot.

For example, the preamble and the mid-amble include pilot signals, such as Demodulation Reference Signals (DMRSs).

Abstract: Methods, systems, devices, and apparatuses are described for location tracking in which each tag used to track an asset or person in an indoor environment transmits ranging waveforms used to estimate a location of the tag. Multiple tags may concurrently transmit without interfering with each other by having each tag use a distinct frequency shift for the ranging waveforms. Access points may be deployed throughout the indoor environment as part of a wireless network (e.g., ultra-wideband or UWB network) that tracks the assets. The access points may receive the ranging waveforms transmitted by the tags and may perform measurements based on the ranging waveforms. The measurements may be sent to a tracking management server to estimate the location of the tags. The server may also determine and assign the distinct frequency shifts used by the tags and may modify the assignment when the number of tags being tracked changes.
