Abstract: Methods, systems, and devices for wireless communications are described in which control resources may be identified, and a data transmission may be rate-matched around the one or more control channels of multiple UEs or at multiple aggregation levels in the control resources. A user equipment (UE) may identify a search space for a first control channel, and the rate-matching of the data transmission may be performed based on a location of the search space in the control resources. In some cases, a base station may provide a mapping of resources (e.g., a bitmap) within the control resources that are occupied, which may be used for rate-matching.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may receive, from a base station, a first downlink control information message in a downlink control channel, the first downlink control information message scheduling first resources of a downlink shared channel for a second downlink control information message. The UE may identify a first, UE-specific scrambling sequence for the second downlink control information message. The UE may receive, from the base station, the second downlink control information message based on the first scrambling sequence, the second downlink control information message scheduling second resources of the downlink shared channel for a data message. The UE may receive, from the base station, the data message in the second resources scheduled by the second downlink control information message.

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 transmit, to another UE, a sidelink channel state information reference signal (S-CSI-RS) and an indication associated with triggering a non-codebook based precoded S-CSI-RS. The UE may receive, from the other UE, the non-codebook based precoded S-CSI-RS. The UE may transmit, to the other UE, a non-codebook based channel state information (CSI) report medium access control (MAC) control element (MAC-CE) that includes an indication of one or more selected precoding beams based at least in part on the non-codebook based precoded S-CSI-RS. Numerous other aspects are described.

Abstract: This disclosure provides a method and apparatus for detecting a transition of a memory cell current from a first state to a second state. An example apparatus includes a memory cell, a supplemental current source, a comparator, a reference voltage and a reference current source in a configuration that allows for real time detection of the transition of a memory cell. Detection of a memory cell current transition is captured when the output of the comparator transitions from one state to a second state in response to a sensing voltage exceeding the reference voltage.
