Abstract: Disclosed are techniques for wireless positioning performed by a user equipment. For example, the method includes entering into a Radio Resource Control (RRC) inactive state. The method includes monitoring, during a first time interval, while the user equipment is in the RRC inactive state, one or more first bandwidth parts having a first bandwidth to perform a first operation. The method includes monitoring, during a second time interval, while the user equipment is in the RRC inactive state, one or more second bandwidth parts having a second bandwidth to perform a second operation. The second bandwidth is different than the second bandwidth.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network, a list of serving cells including a first serving cell that is using a control resource set (CORESET) for single frequency network (SFN) transmissions. Additionally, the UE may receive, from the network, a control element indicating two transmission configuration indicator (TCI) states and associated with the first serving cell and the CORESET. Accordingly, the UE may process the control element based at least in part on determining that one or more additional serving cells in the list are not using the CORESET for SFN transmissions. Numerous other aspects are described.

Abstract: A method of wireless communication by a user equipment (UE) in a non-terrestrial network (NTN) includes transmitting a first small data transmission to a base station during a first transmission occasion associated with a first NTN beam, while the UE remains in an inactive mode or idle mode. The method further includes identifying a switch from the first NTN beam to a second NTN beam. The method still further includes transmitting a subsequent small data transmission to the base station during a second transmission occasion associated with the second NTN beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a beam failure detection (BED) reference signal set in one or more slots in a full-duplex mode and in one or more slots in a half-duplex mode. The UE may detect beam failure due to self-interference based at least in part on a comparison of measurements of the BFD reference signal set in the full-duplex mode and half-duplex mode. The UE may switch from the full-duplex mode to the half-duplex mode for slots configured for the full-duplex mode based at least in part on detecting beam failure due to self-interference. Numerous other aspects are described.

Abstract: The present disclosure relates to methods and devices for wireless communication at an apparatus, e.g., a UE or a base station. The base station may be configured to configure one or more RACH resources for a FD RACH configuration and transmit, to at least one UE, an indication of the one or more RACH resources configured for the FD RACH configuration. The UE may be configured to receive the indication of the FD RACH configuration for the one or more RACH resources. The UE may further be configured to select, based on the received indication, at least one RACH resource of the one or more RACH resources for the FD RACH configuration and transmit, to the first base station via the selected at least one RACH resource, at least one message of a RACH procedure based on the FD RACH configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of sub-bandwidth part (BWP) channel configurations for wireless communications at the UE, where each sub-BWP channel configuration of the set of sub-BWP channel configurations may include one or more sets of resources spanning at least a portion of a respective BWP in the frequency domain. The UE may receive, from the base station, a control message indicating a first sub-BWP channel configuration of the set of sub-BWP channel configurations, the first sub-BWP channel configuration supporting wireless communication for a full-duplex communication mode and a half-duplex communication mode. The UE may communicate with the base station during a first transmission time interval (TTI) using the first sub-BWP channel configuration indicated via the control message and based on the full-duplex communication mode or the half-duplex communication mode.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling indicating a configuration for use by the UE to select one or more of a plurality of resource sets for a bandwidth part (BWP) for the UE, where each of the resource sets comprise reference signal resources that correspond to one or more antenna ports of the UE. The UE may receive, from the base station, an activation message instructing the UE to activate at least one resource set of the plurality of resource sets for reference signal transmission using the BWP. The UE may transmit a reference signal over the activated resource set using the BWP and at least one antenna port of the one or more antenna ports based at least in part on the activation message, the antenna port corresponding to the activated resource set.

Abstract: Methods, systems, and devices for wireless communications are described that support signaling of compressed gradient vectors in a machine learning system that utilizes federated learning. The compressed gradient vectors may be used to report stochastic gradients from multiple edge devices (e.g., multiple user equipment (UE) devices) that are combined into a global model at an edge server (e.g., a base station). A base station may configure a UE with one or more parameters for quantizing a local stochastic gradient, and for reporting the quantized local stochastic gradient in a set of compressed gradient vectors. Each vector of the compressed gradient vectors may be associated with a different stage of a multi-stage compression procedure for reporting the local stochastic gradient, and multiple reports from multiple UEs may be aggregated in a federated learning procedure associated with a machine learning algorithm.
