Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may convey uplink control information (UCI) to a base station using a multi-slot or single slot uplink channels. In some cases, however, transmissions scheduled on a first set of resources allocated for multi-slot transmission of a first uplink channel may overlap with one or more slots of a second set of resources allocated for multi-slot transmission of a second uplink control channel. Accordingly, the UE may employ a number of different techniques to transmit the UCI. In a first case, the UE may map the UCI to at least one of the overlapping slots of the first uplink channel. In a second case, the UE may drop the second uplink channel which carries the UCI. In a third case, and the UE may map the UCI to an overlapping slot of the second uplink channel.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, devices may implement multiple autoencoders for communications. A wireless device may select an autoencoder to use for communications based on a size parameter for a message. For example, a user equipment (UE) may receive a grant from a base station indicating a size parameter for communicating a message. The UE and base station may determine, from a set of neural network (NN)-based encoders configured at the UE, an NN-based encoder corresponding to the size parameter. The UE may communicate the message with the base station according to the grant and based on the determined NN-encoder. In some examples, the UE and base station may determine a number of resource segments from a set of resources allocated for communication and may determine respective NN-based encoders for the different resource segments.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for transmitting a channel state information (CSI) report from a user equipment (UE). The CSI report may be a UE initiated CSI report or may be based on a downlink grant. The UE may receive a downlink grant scheduling a physical downlink shared channel (PDSCH) and a demodulation reference signal (DMRS). The UE may determine to report a CSI in response to a measurement of a downlink measurement resource or in response to the downlink grant requesting the CSI. The UE may determine a reserved uplink resource on which to report the CSI. The UE may transmit a CSI report on the reserved uplink resource.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a single downlink control information (DCI) to indicate two multicast physical downlink shared channels (PDSCHs) for UEs of different capabilities. With the single DCI, different UEs with different capabilities may each receive separate PDSCHs, but the base station may transmit a single downlink control channel to signal the single DCI. The DCI may contain information for each of the multicast PDSCHs, such as a modulation and coding scheme, a time-domain resource assignment, a frequency-domain resource assignment, an antenna ports configuration, etc. for each multicast PDSCH. Subsequently, each UE may receive corresponding multicast PDSCHs parameters from this DCI based on the UE type or capability and may monitor for and receive a corresponding PDSCH from the base station. Additionally, the base station may transmit an activation message for the UEs to receive the single DCI.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit one or more synchronization signal blocks (SSBs), each SSB including a system information block (SIB), to one or more user equipments (UEs). A UE of the one or more UEs may select an SSB with a corresponding SSB index for receiving a SIB and subsequently a multicast transmission from the base station. The multicast transmission may include transmitting a multicast control channel, a multicast traffic channel, or both. The SIB may include one or more parameters for receiving the multicast transmission. The UE may identify one or more monitoring occasions for monitoring a physical downlink control channel for scheduling the multicast transmission based on the SSB index. The UE may receive the multicast transmission in accordance with the one or more parameters from the physical downlink control channel during the one or more monitoring occasions.

Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may receive, from a network entity, information indicating one or more of sounding reference signal (SRS) ports selected by the network entity and associated linear combination coefficients, determine subband precoding based at least in part on the selected SRS ports and linear combination coefficient, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.
