Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive first control signaling indicating a configuration that associates a plurality of resource indicator values with a downlink resource and a plurality of different guard band sizes with the downlink resource. The UE may receive second control signaling indicating a schedule for a downlink transmission in the downlink resource and indicating a first resource indicator value of the plurality of resource indicator values. The UE may monitor the downlink resource for the downlink transmission based on the first control signaling, the second control signaling, and a guard band positioned relative to the downlink resource that has a first guard band size of the plurality of different guard band sizes that is associated with the first resource indicator value.

Abstract: Methods, systems, and devices for wireless communications are described. A full-duplex device may perform a channel access procedure using multiple threshold values to determine whether self-interference at the full-duplex device is affecting the channel access procedure. For example, if a first amount of energy detected during a first sensing operation of the channel access procedure is determined to be between a first threshold value and a second threshold value, the full-duplex device may perform a self-interference measurement on the shared channel and may transmit on the shared channel if the self-interference measurement exceeds a self-interference threshold value. Additionally or alternatively, if the self-interference measurement does not exceed the self-interference threshold value, the full-duplex device may refrain from transmitting on the shared channel. In some examples, the self-interference measurement may include a correlation measurement, a signal-to-noise ratio (SNR) measurement, or a combination thereof.

Abstract: Full-duplex communication techniques are described. Some aspects may utilize full-duplex-slot formats, such as may be provided in addition to or in the alternative to uplink, downlink, and flexible slot formats. A full-duplex slot implemented in accordance with a full-duplex-slot format provides a slot in which the frequency band may be used for both uplink and downlink transmissions. Downlink and/or uplink transmissions of a full-duplex slot may occur in overlapping frequency bands or in adjacent frequency bands. A first wireless device may transmit slot signaling comprising one or more full-duplex-slot-indicator parameters. A second wireless device may base one or more full-duplex slot configuration determinations on a full-duplex-slot configuration. The second wireless device may apply one or more full-duplex-slot-indicator-parameter rules with respect to full-duplex-slot-indicator parameters for determining a full-duplex-slot format. Other aspects and features are also claimed and described.

Abstract: Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal (SRS) to the base station. The base station characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. As part of applying the channel information, the base station forms the beam to the UE based on the uplink channel information obtained from the SRS. The UE may include an array of antennas, each UE transmitting a different SRS that the base station receives and uses to characterize the downlink. Multiple UEs (or a single UE with multiple antennas) transmit SRS at the same time and frequency allocation (non-orthogonal), but with each sending its own unique SRS. Further, multiple UEs (or a single UE with multiple antennas) may send their SRS at unique time/frequency allocations (orthogonal).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station via the transceiver, an indication to apply an amplitude drooping based at least in part on an uplink band being adjacent to a downlink band in a full-duplex operation. The UE may transmit, to the base station via the transceiver, an uplink transmission in the uplink band based at least in part on the amplitude drooping. Numerous other aspects are described.

Abstract: Techniques are provided for calibrating group delay for a low-tier UE by leveraging the relatively high accuracy of RTT positioning for a premium UE. This can enable online/in-field group delay calibration of low-tier UEs, allowing for low-tier UEs to be calibrated when needed. Depending on desired functionality, techniques for calibration may include the use of RTT measurements with a base station, or an RTT measurement between the low-tier UE and the premium UE.

Abstract: Methods, systems, and devices for dynamically configuring connected discontinuous reception (C-DRX) configurations supporting network power modes are described. In some examples, a user equipment (UE) may receive a first control signaling configuring the UE with multiple C-DRX configurations, each C-DRX configuration of the multiple C-DRX configurations corresponding to a respective network power mode. In some examples, the UE may receive a second control signaling including an identifier indicating a C-DRX configuration, of the multiple C-DRX configurations, corresponding to a first network power mode (e.g., an enhanced network power savings mode) at a base station, where the first network power mode may indicated a set of features active at the base station. The UE may communicate with the base station in accordance with the indicated C-DRX configuration and based on the first network power mode.
