Abstract: Apparatuses and methods for wireless communication are provided. In an aspect, a user equipment (UE) receives a DCI from a base station, the DCI including an update to a periodically-occurring scheduling, where an absolute time for the update to take effect is specified in an RRC configuration of the DCI. The UE applies the update to the periodically-occurring scheduling for communications of the UE beginning at and following the absolute time. In another aspect, the UE receives at least one downlink communication that updates a plurality of SPS or CG parameters. The UE determines an action time for the update to take effect for each parameter, where the action time is a function of a type of each parameter. The UE applies the update to each parameter for communications of the UE beginning at and following a respective action time.

Abstract: Methods and devices for discontinuous reception signaling for wireless communications systems are described. A base station may determine a semi-persistent scheduling (SPS) configuration and a discontinuous reception configuration (DRX) associated with the semi-persistent scheduling (SPS) configuration for a user equipment (UE). The base station may transmit the SPS configuration to the UE. The SPS configuration may indicate one or more DRX parameters for the DRX configuration. A UE may receive the semi-persistent scheduling configuration from the base station. The UE may identify one or more DRX parameters for the discontinuous reception configuration based on the SPS configuration. The UE may monitor a downlink control channel in accordance with the DRX configuration.

Abstract: Certain aspects of the present disclosure provide techniques for determining an energy per resource element (EPRE) ratio for non-zero power (NZP) channel state information reference signals (CSI-RSs) when a device is measuring a wireless channel. A method that may be performed by a user equipment (UE) includes determining, based on an indication, an energy per resource element (EPRE) ratio for a non-zero power (NZP) channel state information reference signal (CSI-RS) resource; and measuring a channel based on the determined EPRE ratio and CSI-RSs associated with the NZP CSI-RS resource.

Abstract: A parameter server located at a base station may coordinate federated learning among multiple user equipment (UEs) using over-the-air (OTA) aggregation with power control to mitigate aggregation distortion due to amplitude misalignment. The parameter server may select a first group of UEs for a first OTA aggregation session of a federated learning round based on a common received power property of each UE in the first group of UEs. The parameter server may transmit a global model to the first group of UEs. Each UE in the first group may train the global model based on a local dataset and transmit values associated with the trained local model. The parameter server may receive, on resource elements for the first group of UEs, a first aggregate amplitude modulated analog signal representing a combined response from the first group of UEs.

Abstract: Certain aspects of the present disclosure provide techniques for reporting and responding to beam failure events based on a receiving cell restriction rule. An example method includes detecting an occurrence of a threshold number of beam failures for a connection between a UE and a set of cells; identifying a candidate beam for restoring the connection between the UE and the set of cells in response to detecting the occurrence of the threshold number of beam failures; transmitting, to one or more cells in the set of cells, a beam failure recovery (BFR) request including an identification of the candidate beam; receiving, from a cell in the set of cells, a BFR response in response to transmitting the BFR request, wherein the BFR response is received according to a restriction rule; and resuming communications with the set of cells based on the BFR response.

Abstract: Methods, systems, and devices for wireless communications are described. Some systems may support the transmission of a predicted negative acknowledgment (NACK) indication for a downlink data message. In some cases, a base station may transmit a downlink data message to a user equipment (UE). The UE may perform a decoding process for the message. The UE may determine whether the decoding process is likely to fail during a first portion of the decoding process prior to completion of the decoding process. The UE may transmit a predicted NACK message to the base station prior to a feedback opportunity configured for the UE to transmit feedback based on a result of the completed decoding process. The base station may determine whether to retransmit the downlink data message based on the predicted NACK message, such that the predicted NACK message may reduce the latency associated with retransmission of downlink data messages.
