Abstract: Aspects of the present disclosure provide a self-contained subframe structure for time division duplex (TDD) carriers. Information transmitted on a TDD carrier may be grouped into subframes, and each subframe can provide communications in both directions (e.g., uplink and downlink) to enable such communications without needing further information in another subframe. In one aspect of the disclosure, a single subframe may include scheduling information, data transmission corresponding to the scheduling information, and acknowledgment packets corresponding to the data transmission. Furthermore, the subframe may additionally include a header and/or a trailer to provide certain bi-directional communications functions.

Abstract: Methods, systems, and devices for wireless communications are described in which a network entity may use a lower power sleep procedure to reduce power consumption, and monitor for a wake-up signal (WUS) from at least one user equipment (UE) during configured WUS occasions. The WUS from one or more UEs may provide information of one or more attributes of data traffic that is present at a transmit buffer of the one or more UEs. A WUS configuration may be provided from a network entity that allows the selection of a particular WUS to indicate one or more attributes of the data traffic at the UE. The WUS may convey information such as buffer status, power headroom, a priority of traffic, latency targets of the traffic, or any combinations thereof. The WUS may also give an indication of a requested duration of an active mode at the network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a downlink configuration including a set of resources for receiving downlink transmissions. The UE may determine, based on the downlink configuration, an uplink configuration including a set of resources for transmitting scheduling requests at a set of scheduling request occasions. In some aspects, the set of scheduling request occasions may be arranged according to a non-uniform spacing pattern in the time domain. The UE may transmit, to a base station, one or more scheduling requests based on the uplink configuration.

Abstract: Certain aspects of the present disclosure provide techniques for configuring data transmission. Aspects relate to determining a data transmission configuration utilizing a machine-learning based algorithm, such as a data transmission configuration for ultra-reliable low-latency communication (URLLC) applications. A method that may be performed by a base station (BS) includes receiving a feedback report from a user equipment (UE) including an indication of a first state corresponding to a plurality of channel condition parameters and determining one or more actions based, at least in part, on the first state. The BS may determining the one or more actions utilizing a machine learning algorithm that uses a second state, where the second state is based, at least in part, on the first state.

Abstract: Techniques for peak-to-average power ratio (PAPR) reduction are described. Wireless devices may use one or more PAPR shaping resources, such as expanded bandwidth and/or pulse-shaping filtering, for shaping a signal to reduce PAPR. For example, expanded bandwidth may be utilized for adding a cyclic affix (CA), such as may comprise a cyclic prefix (CP), cyclic suffix (CS), etc., and combinations thereof, to a frequency domain data signal to provide a CP augmented frequency domain data signal used to generate a reduced PAPR time domain data signal. Additionally or alternatively, pulse-shaping filtering may be applied to a frequency domain signal to provide a pulse-shaped frequency domain data signal used to generate a reduced PAPR time domain data signal. Other aspects and features are also claimed and described.

Abstract: Aspects of the present disclosure include methods and devices for informing a base station of autonomously selected SL resources to allow the base station to adjust the DL transmission to mitigate the degradation of the reception of a DL transmission due to self-interference that overlaps with a SL transmission. A device may be configured to select resources for a SL transmission and to transmit, in an UL transmission to a base station, an indication of the resources selected for the SL transmission. A base station may be configured to receive, in an UL transmission, an indication of resources selected for a SL transmission from a UE, and to transmit, based on the indication of the resources selected for the SL transmission, at least one DL transmission that overlaps in time with the SL transmission.

Abstract: A base station performs joint channel estimation for a set of physical uplink shared channels (PUSCHs) with bundled DMRS from a user equipment (UE). The UE receives an indication to transmit the set of PUSCHs, each PUSCH of the set of PUSCHs comprising a corresponding DMRS from the base station. The base station transmits, and the UE receives, a sounding reference signal resource indicator for each PUSCH of the set of PUSCHs. The UE transmits the PUSCHs based on a same sounding reference single resource, the SRI for a first PUSCH of the set of PUSCHs indicating the same SRS resource.
