Abstract: In some implementations, a ultra-wideband (UWB) device comprises a Global Anchor for a network of UWB anchors having a plurality of clusters and initiator anchors (Init-Anchors). The Global Anchor may obtain metric information comprising a centrality metric value of each Init-Anchor from information communicated to the Global-Anchor in a first control phase. The Global Anchor may determine a slot schedule for a second control phase, wherein: determining the slot schedule is based on the centrality metric values of the plurality of Init-Anchors; the slot schedule comprises an allocation of time slots of the second control phase among the plurality of Init-Anchors for wireless radio frequency (RF) communication; and the allocation of time slots includes a first set of time slots for upstream communication followed by a second set of time slots for downstream communication. The Global Anchor may send the slot schedule to an Init-Anchor of the plurality of Init-Anchors.

Abstract: A base station may precode a first reference signal using a first precoder (P1) and at least one second reference signal using at least one second precoder (P2). At least two UEs may measure the first reference signal and the at least one second reference signal, and transmit channel state feedback based on the measuring (m11 and m12 for a first UE, and m21 and m22 for a second UE). The channel state feedback may comprise channel state information compressed by at least one neural network. The base station may derive a higher-level precoder (W) for multiple-input multiple-output (MIMO) downlink transmission to the at least two UEs.

Abstract: Some techniques and apparatuses described herein provide reporting of multiple feedbacks for a same transport block (TB) or a same code block group (CBG) of a signal, such as a physical downlink shared channel. Thus, in case of a failure to decode a signal via a first set of antennas, a user equipment (UE) can perform a second decoding attempt via a second set of antennas (before or after transmitting first feedback). The UE may report a result of the first decoding attempt in a first feedback, and may report a result of the second decoding attempt in a second feedback. Some techniques and apparatuses described herein also provide soft feedback (e.g., information other than a binary acknowledgment (ACK) or negative ACK (NACK)) for a transmission, such as information indicating whether a second attempt to decode the transmission is likely to be successful.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may be configured to transmit one or more reference signals to a second wireless device using a first antenna array at the first wireless device and in accordance with a first precoder matrix. The first wireless device may receive, from the second wireless device based on the one or more reference signals, a feedback message indicating an estimated rotational misalignment, an estimated spatial misalignment, or both, between the first antenna array at the first wireless device and a second antenna array at the second wireless device. The first wireless device may then transmit a message to the second wireless device in accordance with a second precoder matrix that is modified relative to the first precoder matrix based at least in part on the estimated rotational misalignment, the estimated spatial misalignment, or both.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) or a base station, or both, may determine a configuration for partitioning a set of sequences into multiple sequence pools associated with multiple UEs. The UE or the base station, or both, may determine a sequence pool associated with the UE based on the configuration, which may include parameters or instructions for determining the sequence pool associated with the UE. The UE or the base station, or both, may select a subset of sequences from the sequence pool associated with the UE and construct a codebook including the subset of sequences. The UE may select a sequence from the constructed codebook based on a quantity of bits of a payload and may transmit the payload to the base station using the selected sequence.

Abstract: Aspects relate to adaptation of the modulation and coding scheme (MCS) of a downlink transmission to a scheduled entity that overlaps in time with an uplink transmission from the scheduled entity when the scheduled entity is operating in a full-duplex mode. A transport block corresponding to the downlink transmission may include a plurality of code block groups (CBGs). When at least a portion of the CBGs overlap in time with the uplink transmission, the MCS of the entire transport block or the MCS of the overlapping CBGs may be adjusted to accommodate and/or mitigate interference between downlink and uplink transmissions. The CBGs may further be time-interleaved over a plurality of symbols allocated for the downlink transmission to accommodate and/or mitigate interference between downlink and uplink transmissions. Other aspects, features, and embodiments are also claimed and described.
