Abstract: Aspects of the disclosure relate to determining channel state information (CSI) on a component carrier. In an example operation, a device determines a mapping between first time-frequency resources corresponding to a first component carrier (CC) and second time-frequency resources corresponding to a second CC using a prediction algorithm. The device receives, from a base station, a channel state information reference signal (CSI-RS) on the first time-frequency resources corresponding to the first CC and measures first CSI on the first time-frequency resources corresponding to the first CC based on the received CSI-RS. The device further predicts second CSI on the second time-frequency resources corresponding to the second CC based on the measured first CSI using the prediction algorithm. The device then generates a CSI report based on the predicted second CSI and sends the CSI report to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for communicating capability information (e.g., regarding neural network blocks supported by a user equipment (UE) and a base station). A base station may configure one or more neural network block parameters, and may transmit the neural network block parameters to the UE. The UE may configure or reconfigure a neural network block according to the neural network block parameters, and may process one or more signals, e.g., baseband signals, generated by the UE using the neural network block and the neural network block parameters.

Abstract: A control resource region of an New Radio system slot structure may be separated into control resource sets, only some of which may be used for control transmissions. Aspects presented herein improve the efficient utilization of resources by enabling data transmission in resources of the DL control resource region and/or the UL control resource region. A UE receives an indication of a control resource set in a control resource region of a slot that may provide a control channel resource or a data channel resource and performs rate matching for data transmissions in the data channel based at least in part on the indication. The indication may be a semi-static indication, e.g., RRC signaling, of the control resource set.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a base station. The apparatus may transmit a first grant to a UE. The apparatus may determine whether an acknowledgment to the first grant is received. When the acknowledgment to the first grant fails to be received by the apparatus, the apparatus may transmit, to the UE, a second grant including information regarding the first grant. In another aspect, an apparatus may be a UE. The apparatus may receive a first grant. The first grant may include a first Mayday bit. The apparatus may receive a second grant. The second grant may include a TTI count corresponding to a number of unacknowledged TTIs. The second grant may further include a second Mayday bit.

Abstract: Methods, systems, and devices are described for wireless communication employing two-stage control channel messaging. Systems, methods, and apparatuses for two stage two-stage physical downlink control channel (PDCCH) with a downlink control information (DCI) flag and DCI format size indicator are described. For instance, the present disclosure presents an example method of wireless communication at a wireless device, which may include receiving, at a first bandwidth and during a transmission time interval (TTI), a first control channel message. In addition, the example method may include determining, based on a flag in the first control channel message, whether a second control channel message is present in the TTI. Furthermore, the example method may include receiving, at a second bandwidth, the second control channel message where the flag indicates that the second control channel message is present for the TTI.
