Abstract: Methods, systems, and devices for configuring physical downlink control channel candidates are described. The method may include monitoring, by a UE, an initial set of physical downlink control channel candidates in a first slot, receiving, by the UE, an indication of an adjusted set of physical downlink control channel candidates to monitor in a second slot based on decoding a physical downlink control channel candidate in the initial set, and monitoring, by the UE in the second slot, the adjusted set of physical downlink control channel candidates. The method may also include adaptively (e.g., autonomously) determining, by the UE, the adjusted set of physical downlink control channel candidates, and corresponding determinations by the base station.

Abstract: Methods, systems, and devices for wireless communications are described that support slot format determination for extended cyclic prefix (ECP) transmissions using normal cyclic prefix (NCP) slot formats. A slot format indicator (SFI) for NCP slots may identify transmission directions (e.g., uplink symbols, downlink symbols, or flexible symbols) for different symbols within a slot, and the SFI may provide an indication of a particular slot format that is to be used. Starting and ending times of each NCP symbol in a slot may be time domain mapped to starting and ending times of each ECP symbol in the slot. A transmission direction of each ECP symbol may be determined based at least in part on the transmission direction of at least a portion of at least one NCP symbol that fully or partially overlaps in the time domain with a corresponding ECP symbol.

Abstract: Certain aspects of the present disclosure generally relate to enhanced procedures for search, measurement, and positioning with aid of motion detection information. According to certain aspects, a method is provided for wireless communications which may be performed, for example, by a user equipment (UE). The method generally includes determining one or more parameters of the UE; dynamically adjusting a periodicity of at least one of: cell search and measurements or global positioning system (GPS) signal acquisition based, at least in part, on the one or more parameters; and performing at least one of: the cell search and measurements or GPS signal acquisition according to the adjusted periodicity. In aspects, an enhanced technique for motion state detection is provided. The method may result in power savings, for example, when the UE is stationary and can reduce the periodicity that the UE performs search, measurement and GPS signal acquisition.

Abstract: Wireless communication devices, systems, and methods related to power saving, including during connected mode operation and for extended reality (XR) data communications with or without discontinuous reception (DRX), are provided. For example, a method of wireless communication includes receiving, while in a connected mode, a configuration based on data traffic for the wireless communication device, the configuration indicating: a first zone associated with a first set of operating parameters for the wireless communication device; and a second zone associated with a second set of operating parameters for the wireless communication device, the second set of operating parameters being different than the first set of operating parameters; operating in the first zone with the first set of operating parameters to monitor for a first downlink communication signal; and operating in the second zone with the second set of operating parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a wake up signal (WUS) within a WUS monitoring occasion (WMO) indicating to initiate a discontinuous reception (DRX) on-duration, a time to initiate the DRX on-duration being based at least in part on a timing of the WMO within a set of WMOs. The UE may receive a communication based at least in part on initiating the DRX on-duration at the time. Numerous other aspects are described.

Abstract: A method by a user equipment (UE) includes receiving at least one time offset for scheduling non-terrestrial communications. The at least one first time offset is configured according to a numerology and/or a bandwidth part (BWP). The UE communicates in accordance with the time offset(s). The time offset may be a single time offset that applies across all numerologies or may be multiple time offsets, each specific to a particular numerology or bandwidth part (BWP). The time offset may be a single time offset scaled based on a current numerology configured for communications. The time offset may apply across different bandwidth parts (BWPs) or across multiple component carriers from which the UE is receiving downlink data.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate over multiple component carriers (CCs). The UE may receive control signaling indicating a joint feedback codebook configuration for jointly reporting feedback for a first CC, a second CC, and a virtual CC that may be mapped to a third CC and a fourth CC. The CE may then receive downlink control information (DCI) scheduling a first downlink transmission via the first CC and a second downlink transmission on the second CC, or both downlink transmissions may be scheduled via the virtual CC. The UE may transmit a joint feedback message for the first CC, the second CC, and the virtual CC based on the joint codebook configuration.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for grouping common DCI for CLI measurement and reporting. In a first aspect, a UE may receive DCI that is common to a group of UEs that includes the UE. The DCI may be configured to trigger at least one of an SRS transmission or a CLI measurement. The UE may transmit the SRS transmission and/or report the CLI measurement based on the DCI that is common to the group of UEs. In a second aspect, a base station may transmit at least one DCI that is common to the group of UEs to trigger the at least one of the SRS transmission or the CLI report for the group of UEs. The base station may receive the CLI report from at least a subset of UEs in the group of UEs.

Abstract: Certain aspects of the present disclosure provide techniques for transmitting demodulation reference signals (DMRS) with control channels (e.g., physical downlink control channels (PDCCHs)) that enable receiving devices to bundle (e.g., coherently combine) the DMRS over time. A UE may detect a portion of a PDCCH to the UE in at least one resource element group (REG), wherein the REG is in a segment of a control resource set (CORESET) configured for the UE or a group of UEs including the UE and the REG is during a first search space (SS) set occasion configured for the UE or the group of UEs; and process wideband (WB) DMRS in the segment during the first SS set occasion and in the segment during at least one second SS set occasion, wherein the UE does not detect another portion of the PDCCH or another PDCCH during the second SS set occasion.
