Abstract: Certain aspects of the present disclosure provide techniques for channel state information measurement adaptation to maximum multiple-input multiple-output layers. A method that may be performed by a user equipment (UE) includes receiving a first channel state information (CSI) report configuration including one or more first CSI reference signal (CSI-RS) resources, wherein each first CSI-RS resource comprises a first resource set; determining, based on an indication of a maximum number of multiple-input multiple-output (MIMO) layers that the UE is expected to receive, a first resource subset on which to report first CSI; and reporting the first CSI to a base station (BS), wherein the first CSI is based on the determined first resource subset.

Abstract: To enable full-duplex communication in a time division duplexing (TDD) band, a network node (e.g., a user equipment (UE)) may be configured to communicate in one or more flexible bandwidth parts (BWPs) using BWP-specific TDD patterns regardless of a TDD pattern configured for the underlying band. However, in some cases, half-duplex communication may offer better performance than full-duplex communication (e.g., when full-duplex communication may cause self-interference or there is a need for high throughput half-duplex communication). Accordingly, some aspects described herein relate to timing considerations and switching indications for indicating an interval in which the network node is to operate in the flexible BWP using the BWP-specific TDD pattern and switching between the BWP-specific TDD pattern and the TDD pattern of the underlying band (e.g., using switching indications based on a number or quantity of transmission time intervals and/or a timer, among other examples).

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment (UE). For example, the UE receives a physical downlink shared channel (PDSCH) channel state information (CSI) report configuration from a network entity. The UE monitors a PDSCH transmission. The UE generates and transmits a CSI report to the network entity, based on the monitoring and in accordance with the PDSCH CSI report configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may determine, within a sub-band full duplex (SBFD) slot, an allocation of first and second virtual resource block (VRB) groups to physical resource blocks (PRBs) across first and second disjoint bandwidth part (BWP) segments based upon one or more VRB-to-PRB mapping rules, and may communicate data over the first and second sets of PRBs in accordance with the allocation.

Abstract: A user equipment may be configured to implement a procedure for combining half-duplex and full-duplex channel state information (CSI) into a single report. In some aspects, the user equipment may receive uplink control information configuration information including one or more parameters for multiplexing half-duplex (HD) channel state information (CSI) and full-duplex (FD) CSI as a combined CSI report, and receive a first reference signal associated with a HD mode and a second reference signal associated with a FD mode. Further, the user equipment may transmit, to a base station, the combined CSI report based on the one or more parameters, the first reference signal, and the second reference signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a power headroom report (PHR) including data indicating power headroom (PH) for the UE, the PH indicating a difference between a maximum output power of the UE and an actual transmission power. The UE may adjust an energy harvesting reception process based at least in part on the PH satisfying a first threshold. Numerous other aspects are described.

Abstract: Techniques are provided for utilizing sounding reference signals (SRS) in full duplex scenarios. An example method for facilitating a measurement of a propagation channel in a wireless network includes receiving first sounding reference signal configuration information associated with a first frequency location in the component carrier, receiving second sounding reference signal configuration information associated with a second frequency location in the component carrier, wherein the second frequency location is disjoint from the first frequency location in the component carrier, and transmitting a first sounding reference signal and a second sounding reference signal based on the respective first sounding reference signal configuration information and the second sounding reference signal configuration information.
