Abstract: Processes, systems, and devices for wireless communications are described. A communication device may monitor a wakeup signal monitoring occasion in an inactive duration of a discontinuous reception (DRX) cycle. The communication device may transmit, in a first active duration of the DRX cycle, a channel state information (CSI) report on one or more resources based on monitoring the wakeup signal monitoring occasion. In some examples, the communication device may transmit an indication that the communication device requests reporting of the CSI report in the first active duration of the DRX cycle. The communication device may, in some examples, receive, in a second active duration of the DRX cycle, control information for the UE based on the CSI report.

Abstract: A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.

Abstract: Bandwidth part (BWP) inactivity and mode switching supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. A wireless device may be provided with multiple BWP configurations, such as may include a default half duplex BWP configuration and a default BWP configuration. Multiple timers, such as may include a BWP inactivity timer and a duplex mode timer, may be implemented for timer-based switching between BWP configurations, such as any combination of a default half duplex BWP configuration, an active half duplex BWP configuration, a default full duplex BWP configuration, and an active full duplex BWP configuration. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a wakeup signal search space (WUS-SS) set for a physical downlink shared channel (PDCCH) wakeup signal (WUS). The UE may detect the PDCCH WUS in the WUS-SS set based at least in part on monitoring the WUS-SS set. Numerous other aspects are provided.

Abstract: Generally, the described techniques provide for duplex mode configuration for control information (e.g., duplex mode configuration for communication of downlink control information). For example, duplex modes may be defined (e.g., as full duplex (FD) capable, FD only, half duplex (HD) only, etc.), and such duplex modes may be configured for control resource sets (CORESETs), search space (SS) sets, or both. In some examples, duplex modes configured for a CORESET/SS set may depend on the priority of information conveyed via the CORESET/SS set. For example, a CORESET/SS set for high priority or critical control information may be configured with a HD mode to avoid FD self-interference, while CORESET/SS set for other control information may be configured with a FD mode to improve spectrum efficiency. Techniques for resolving conflicting duplex mode configurations (e.g., when a HD mode is configured for a SS set within a CORESET configured with FD) are also described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a guard period associated with switching from a first communication mode to a second communication mode. The UE may be operating in a half-duplex frequency division duplexing mode of operation. The guard period may be determined based at least in part on at least one of: a number of phased locked loops to be used for the first communication mode and the second communication mode, and a particular subcarrier spacing associated with the UE. The UE may switch from the first communication mode to the second communication mode based at least in part on the guard period. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, based at least in part on the UE being a reduced-capability UE, control information on a reduced capability control resource set (CORESET) at least partially in a reduced capability region of a CORESET region, wherein the reduced capability CORESET is associated with a reduced configuration relative to a CORESET for a non-reduced-capability UE; and communicate in accordance with the control information. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide various flexible search space designs that can handle UEs with various capabilities and limitations. In some aspects of the disclosure, the downlink bandwidth may be divided into several self-contained sub-bands. Each sub-band may include one or more OFDM subcarriers or tones, and each UE may be configured to monitor one or more of the sub-bands for its downlink control channel. The sub-band is self-contained in such a way that each sub-band includes CCEs that are mapped to resource elements contained in the same sub-band. In some aspects of the disclosure, different sub-bands can be configured with the different transmission modes and pilot densities. The transmission mode, pilot density, and layer-ID may be determined as a function of each UE's search space.

Abstract: A UE may be configured for half-duplex communications. An access point may configure half-duplex UEs for efficient resource utilization using two or more different half-duplex configurations that include different timing for channels in different directions. A UE may determine a half-duplex configuration for use in communicating with the access point, each slot of the half-duplex configuration including at least a PDCCH on a downlink frequency and an uplink short burst on an uplink frequency, and each slot associated with a HARQ timeline. The UE may determine a direction for a slot. The UE may transmit or receive according to the direction for the slot and the half-duplex configuration.
