Abstract: Systems and method for providing downlink control information (DCI) sizes prioritization rules to enable a wireless network to monitor and decode a number of DCI sizes without exceeding a DCI sizes budget of a UE are disclosed. In embodiments, a UE monitors for a downlink control information (DCI) message having one of a number of different formats and one of a number of different sizes. The UE is configured with a DCI sizes budget indicating a number of different DCI sizes that the UE is configured to decode. The UE applies a DCI sizes prioritization rule to generate a prioritized set of DCI sizes. The prioritized set of DCI sizes includes a number of DCI sizes to be monitored, which is less than or equal to the DCI sizes budget. The UE decodes the DCI message based on the prioritized set of DCI sizes.

Abstract: Aspects are provided which allow a user equipment (UE) to identify a low-bandwidth (low-BW) CORESET-0 and associated CSS based on reception bandwidth of the UE. The base station may configure different frequency and time-domain resources of the low-BW CORESET in order to optimize resource utilization of the low-BW CORESET-0, and the low-tier UE may identify these resources of CORESET-0 and CSS from the system configuration information received in a master information block (MIB). As a result, low tier UEs may operate in a same cell as legacy UEs without the need for the base station to transmit additional signaling to either legacy UEs or lower tier UEs for the UEs to receive their respective CORESET-0's and identify a physical downlink channel (PDCCH).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine that a user equipment (UE) is to use a differential reporting mode based at least in part on a channel state information (CSI) report from the UE. The base station may transmit to the UE, signaling to cause the UE to use the differential reporting mode based at least in part on determining that the UE is to use the differential reporting mode. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message identifying a backbone model that is combinable with at least one task-specific model to generate a multi-model machine learning application. The UE may receive the backbone model and a first task-specific model identified by the control message. The UE use a multi-model machine learning application that is a combination of the backbone model and the first task-specific model to process one or more received signals to generate one or more outputs. The UE may communicate with a wireless device based on the one or more outputs.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform channel state information (CSI) measurements on one or more reference signal transmissions received from a base station. Based on the CSI measurements, the UE may generate a CSI report, and the UE may transmit the CSI report to the base station. In some cases, the generated CSI report may include a first portion and a second portion. The first portion may indicate whether the second portion of the CSI report includes full-band CSI feedback or partial-band CSI feedback. The second portion may provide the CSI feedback for one or more identified sub-bands. In some cases, the second portion may include a sub-band index indicating the identified sub-bands. Additionally or alternatively, the second portion may include a bitmap indicating a correspondence between multiple CSI feedback values and multiple corresponding sub-band indexes.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for managing remote interference using a previously detected relationship between an aggressor base station and a victim base station. The described techniques provide for allocating reference signal sequences for various victim base stations to send to an aggressor base station. The victim base station may trigger the aggressor base station to perform reference signal monitoring based on the previously detected victim-aggressor relationship, and may transmit a reference signal carrying a unique identifier based on the triggering. The first base station may send a request that the second base station to transmit a reference signal for enabling the first base station to measure interference of a wireless channel, and performing interference mitigation techniques at the first base station, the second base station, or both, to mitigate the remote interference.
