Abstract: Aspects relate to cross-carrier scheduling in wireless communication. A scheduling entity generates scheduling information that schedules a plurality of data transmissions to or from a user equipment (UE) on a first carrier having a first numerology. The scheduling entity then transmits the scheduling information to the UE on a second carrier having a second numerology different than (e.g., less than) the first numerology. The scheduling information is transmitted using control resources allocated based on slot indexes of a plurality of slots configured for communicating the data transmissions on the first carrier.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide signaling formats to cause a UE to switch to an active BWP in a secondary cell (SCell) secondary cell group (SCG). The techniques may be used when the UE is connected to a secondary node on a dormant BWP such that the UE connects to the secondary node on the active BWP. The UE may receive, from a master node, downlink control information (DCI) indicating a transition to an active BWP for the communication link with the secondary node. The UE may then perform a communication with the secondary node on the active bandwidth part in accordance with the DCI. The DCI may include SCell or SCG bitmaps, extra bits that signal to the UE that an activation corresponds to a SCG, and/or RNTIs that signal to the UE that the activation corresponds to a SCG.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, cross-link interference information identifying a cross-link interference strength at the second UE; determine an uplink transmit power based at least in part on the cross-link interference strength at the second UE; and transmit, on an uplink, using the determined uplink transmit power. 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 select a downlink control information (DCI) mode to be used by the UE, wherein the selected DCI mode is one of: a joint DCI mode in which a DCI for an uplink and a DCI for a downlink are monitored jointly, or a separate DCI mode in which one or more of the DCI for the uplink or the DCI for the downlink are monitored separately; and monitor at least one of the DCI for the uplink or the DCI for the downlink in accordance with the selected DCI mode. Numerous other aspects are provided.

Abstract: Techniques and apparatus for intra-frequency measurement of Layer 3 (L3)-based channel state information reference signals (CSI-RSs) are described. An example method that may be performed by a user equipment (UE) includes transmitting an indication based on a UE capability to simultaneously receive downlink data from a serving cell on one or more first resources and measure one or more CSI-RSs from a target cell on one or more second resources. The one or more first resources at least partially overlap the one or more second resources in a time domain and a frequency domain. The method also includes performing a CSI-RS measurement procedure, based on the UE capability.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication for applying resource element (RE) skipping to a symbol where a beam change is to occur. A transmitter and a receiver determine that a beam change is to occur during the symbol. The transmitter allocates bits to a subset of REs for the symbol in a frequency domain allocation. Each RE of the subset is spaced apart by a number of empty REs. The transmitter performs an inverse fast Fourier transform (IFFT) on the REs to generate a time domain signal including a number of repetitions of a transmitted waveform. The receiver receives the time domain signal during at least a portion of the symbol. The receiver performs a fast Fourier transform (FFT) on the time domain signal and determines transmitted bits or a channel from the subset of REs output from the FFT.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a resource for measuring cross link interference (CLI). The UE may determine that the resource overlaps with (e.g., at least partially overlaps) one or more symbols or a transmission occasion. The UE may determine, according to what the resource overlaps with, whether to measure CLI over the resource. For example, if one or more of the symbols is uplink or if the resource verlaps a transmission occasion, the UE may not measure CLI. If one or more of the symbols are downlink, the UE may measure CLI. If one or more of the symbols is flexible or has an unknown type, the UE may determine whether to measure CLI based on a type of the control signaling.
