Abstract: In an aspect, a network component (e.g., BS, server, etc.) obtains measurement information associated with uplink signal(s) from UE(s), with the uplink signal(s) having reciprocity with one or more downlink beams of wireless node(s) (e.g., TRP, reference UE, etc.). The network component determines (e.g., generates or refines) a measurement (e.g., RFFP-P) model based on the measurement information. The network component provides the measurement (e.g., RFFP-P) model to a target UE. The target UE receives at least one signal (e.g., PRS) on the one or more downlink beams from the wireless node(s). The target UE processes the at least one signal (e.g., predicts target UE location) based at least in part on the measurement (e.g., RFFP-P) model.

Abstract: Aspects relate to techniques for enhancing sidelink scheduling information to include a priority assigned to a sidelink transmission. For example, a transmitting wireless communication device may receive sidelink scheduling information scheduling a sidelink transmission from a transmitting wireless communication device to a receiving wireless communication device. The sidelink scheduling information may further include a priority indicator associated with the sidelink transmission. The transmitting wireless communication device may then transmit the sidelink transmission to the receiving wireless communication device based on the scheduling information. The priority indicator may further facilitate hybrid automatic repeat request (HARQ) codebook construction on the sidelink and uplink for the transmission of acknowledgement information of the sidelink transmission.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving, from a network device, a request to initiate gradient computations for a round of federated learning. The method also includes computing gradients in response to receiving the request to initiate gradient computation. The method further includes informing the network device of availability of the gradients. The method still further includes receiving, from the network device, information to enable transfer of the gradients to the network device. The method further includes transferring the gradients to the network device in response to receiving the information to enable transfer.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for propagation delay compensation (PDC). In some systems, a network entity and a group of user equipment (UEs) may support a group-based PDC procedure according to which the network entity may provide group-based PDC information to the group of UEs. In some aspects, a UE may participate in such a group-based PDC procedure in accordance with a clock accuracy constraint of the UE and depending on whether other UEs are likely to have similar PDC information. The network entity may assign an identifier (ID) to the group of UEs and scramble a message including the group-based PDC information using the ID. As such. UEs of the group of UEs may decode the message using the ID and adjust a timing of communications with the network entity using the group-based PDC information.

Abstract: Aspects presented herein may enable a network entity to calculate a relative clock drift between a Tx antenna panel and an Rx antenna panel that use different RF hardware/circuits (e.g., clocks). In one aspect, a network entity obtains a plurality of RTT measurements between a Tx antenna panel, a device with a known position, and an Rx antenna panel over a period of time, where the Tx antenna panel is associated with a first clock and the Rx antenna panel is associated with a second clock. The network entity obtains a first timing delay associated with the device based on the plurality of RTT measurements. The network entity calculates a clock offset between the Tx antenna panel and the Rx antenna panel based on the obtained first timing delay associated with the device.

Abstract: A method of wireless communication by a user equipment (UE) includes generating, by an upper analog media access control (MAC-A) layer of a protocol stack, a data packet with a header and a data field. The header indicates a neural network identifier (ID) and a request ID. The data field includes gradient data for a federated learning iteration. The method also includes transferring the data packet to lower layers of the protocol stack for transmission to a network device across a wireless network.

Abstract: A method for redirecting a user equipment (UE) from a first network to a second network is described. The method includes determining, at a wireless access point of the first network, information for the UE about one or more mobile network operator (MNO) networks. The method also includes selecting the second network for redirection from among the one or more MNO networks based on the determined information. The method further includes sending the UE a redirection message that redirects the UE from the first network to the second network.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving a configuration message indicating a group common control resource allocated to a set of UEs that includes the UE, identifying a hashing function assigned to the UE for detecting control messaging communicated via the group common control resource that is addressed to the UE, receiving, via the group common control resource, a control message indicating addressing data and a bitmap, and processing the addressing data using the hashing function and the bitmap to determine applicability of the control message to the UE.

Abstract: Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may receive, from a base station, a logged measurement configuration including a PLMN ID and a NID, the logged measurement configuration further including at least one of a trace reference, a logging area, a MDT PLMN list, or a MDT NPN list. The apparatus may also store the PLMN ID and the NID based on the received logged measurement configuration. Additionally, the apparatus may compare the PLMN ID and the NID to an MDT SNPN list to identify if the PLMN ID and the NID are included in the MDT SNPN list. The apparatus may also transmit, to the base station, an availability indicator if the PLMN ID and the NID are included in the MDT SNPN list.
