Abstract: Aspects relate to wireless communications utilizing cross carrier scheduling Methods and apparatus include generating at least one slot in a control channel from a scheduling cell, the at least one slot including a plurality of control channel segments such as PDCCH segments, which are arranged at respective times within the at least one slot. Each of the control channel segments includes control information such as DCIs corresponding to respective slots for a scheduled cell. Distributing the control channel information in segments or spans over time affords improved decoding timing in a UE in the scheduled cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) supporting full duplex communications may determine that a set of downlink messages to be transmitted from a base station to the UE overlaps in time with a set of uplink messages to be transmitted from the UE. Accordingly, the UE may determine a downlink transmission power adjustment value for the set of downlink messages. In some examples, the base station may indicate the downlink transmission power adjustment value to the UE via radio resource control (RRC) signaling, a downlink control information (DCI) message, or both. The UE may transmit the set of uplink messages while simultaneously receiving the set of downlink messages with a transmission power that corresponds to the downlink transmission power adjustment value. Adjusting the transmission power for the set of downlink messages may reduce self-interference at the UE, the base station, or both.

Abstract: This disclosure provides systems, methods and apparatuses for identifying physical downlink control channel (PDCCH) parameters, such as a PDCCH blind decode limit and a PDCCH control channel element limit, for implementations where a user equipment (UE) is configured with two or more cell groups. The techniques described herein permit the UE or a base station to determine the quantity of cell groups that is to be considered when determining the PDCCH parameters, permit the UE to indicate PDCCH capability values across multiple frequency ranges, and permit the base station to schedule a quantity of PDCCHs for the UE that results in a quantity of blind decodes that exceeds a PDCCH blind decode limit or a quantity of control channel elements that exceeds a PDCCH control channel element limit.

Abstract: Methods, systems, and devices for wireless communications are described. Sidelink communications between user equipments (UE)s may include services that demand low latency and high reliability, such as extended reality (XR) and ultra-reliable low latency communications (URLLC). Given the latency demands for XR and URLLC, XR and URLLC may be higher priority than other communications types. A UE may determine that data for transmission over sidelink has a high priority level based on a remaining packet delay budget associated with the data. UEs may monitor for sidelink transmissions in accordance with network configured discontinuous reception (DRX) cycles. The DRX cycles configured by the network for sidelink communications, however, may not match with the periodicity of XR traffic. For XR communications, the transmitting UE may indicate an offset to apply to a DRX cycle such that the receiving UE may adjust the DRX cycle to match the periodicity of the XR communications.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be instructed to, or may autonomously determine to, extend a monitoring time period (e.g., by extending the on duration to cover more downlink transmissions, or by extending the on duration and continuing to monitor after on durations, or both). In some examples, a wakeup signal (WUS) or a downlink control information (DCI) message may explicitly indicate an amount of time to extend the on duration or inactivity timer (or to pause the inactivity timer). In some examples, the network may configure the UE with a power threshold (e.g., charging rate, discharging rate, energy harvesting rate, current power levels, or power headroom), or a traffic rate (e.g., number of transport blocks per time interval), and the UE may autonomously extend the on duration or timer if its energy levels or traffic rate exceeds the threshold.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive from a base station a measurement configuration signal comprising a measurement resource configuration associated with a cross-link interference signal strength measurement. The UE may perform the cross-link interference signal strength measurement for one or more UEs associated with one or more intra-frequency neighboring cells according to the measurement resource configuration, wherein the cross-link interference signal strength measurement is performed during an intra-frequency measurement gap. The UE may transmit a report of the cross-link interference signal strength measurement to the base station.

Abstract: Aspects relate to dynamically changing the slot format of a slot between half-duplex and sub-band full-duplex and/or to changing flexible symbols within a flexible slot between half-duplex and sub-band full-duplex when a base station is configured to operate in a sub-band full-duplex mode. A slot format indicator (SFI) indicating the slot format of the slot may be signaled, for example, via downlink control information (DCI) mapped to a downlink control channel or medium access control (MAC) control element (MAC-CE) mapped to a downlink data channel. To improve reliability, various SFI boosting mechanisms may further be employed. For example, the base station may apply a higher aggregation level to the SFI, transmit repetitions of the SFI across multiple beams, apply a CRC enhancement and/or MCS enhancement to the downlink control channel carrying the SFI, and/or apply a power boost to the SFI.

Abstract: The described techniques relate to improved methods, systems, devices, and apparatuses that support interference mitigation for remote devices. A first wireless device (e.g., a base station) may detect remote interference with its communications caused by a second wireless device (e. g., a second, remote base station) based on, for example, a measured interference over thermal noise level exceeding a threshold. The first wireless device may identify a set of time-frequency resources for remote interference reference signals and a data transmission for a user equipment (UE) that is in communication with the first wireless device. The first wireless device may transmit a remote interference signal to a second wireless device (e. g., a second base station) via the set of time-frequency resources. The first wireless device may further signal a resource allocation to the UE for the UE to use for transmitting uplink transmissions to the first wireless device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may transmit configuration information indicating a first precoding matrix indicator (PMI) parameter and a second PMI parameter, wherein the first PMI parameter is associated with non-simultaneous activity of a distributed unit (DU) and a mobile termination (MT), and wherein the second PMI parameter is associated with simultaneous activity of the DU and the MT. The wireless node may perform a communication in accordance with a selected PMI parameter of the first PMI parameter and the second PMI parameter based at least in part on whether the DU and the MT are simultaneously active. Numerous other aspects are described.

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.
