Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station, and a processor communicatively coupled to the transceiver. The processor is configured to receive a configuration message from the base station, wherein the configuration message indicates a model identifications (ID) and one or more signals and measure the one or more signals to generate a data set corresponding to the model ID. The processor is further configured to train a first artificial intelligence (AI) model corresponding to the model ID using the data set; generate a second data set corresponding the model ID; and transmit the second data set and the model ID to the base station. The second data set is used to train a second AI model corresponding to the model ID.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for relaxing evaluation of radio link quality. According to embodiments of the present disclosure, a terminal device transmits, to a network device, capability information indicating a capability of the terminal device to relax an evaluation of a radio link quality. The terminal device receives, from the network device, a relaxation configuration for relaxing the evaluation. The terminal device performs the evaluation using a relaxed evaluation period determined based on the relaxation configuration. The relaxed evaluation period is longer than a normal evaluation period without relaxing the evaluation.

Abstract: Systems and methods for beam failure recovery (BFR) are disclosed herein. A user equipment (UE) receives downlink (DL) reference signal(s) on corresponding beam(s) from a base station. The UE performs beam failure detection (BFD) on such beams used for user data to determine whether a beam failure has occurred, and candidate beam detection (CBD) on such beams not used for user data to identify candidate beams for recovering from the beam failure. The BFD and the CBD are based on both uplink (UL) channel performance considerations and DL channel performance considerations, as determined using the DL reference signal(s), such that a beam failure may be determined in the UL, the DL, or both, and a candidate beam may be identified for UL, DL, or both. The UE sends a beam failure recovery request BFRQ with this information to the base station, and the system changes beams accordingly.

The UE receives configuration information associated with inserting phase tracking-reference signals (PT-RS) into a physical uplink control channel (PUCCH) signal, generates a first signal that is to be transmitted over the PUCCH and is configured to include one or more PT-RS and transmits the first signal over the PUCCH. The UE may also generate a second signal that is to be transmitted over the PUSCH and is configured to include one or more PT-RS, wherein the configuration information further comprises configuration information associated with inserting PT-RS into a physical uplink control (PUSCH) signal and transmit the second signal over the PUSCH, wherein the PUCCH and PUSCH transmissions are performed simultaneously over different component carriers (CCs).

Abstract: Systems and methods disclosed herein relate to acknowledgement signaling sent by a user equipment (UE) in response to downlink control information (DCI) received from a base station that schedules the use of multiple physical uplink control channels (multi-PUSCH) or multiple physical downlink control channels (multi-PDSCH). Acknowledgement signaling may inform the base station that DCI scheduling the multi-PUSCH/multi-PDSCH was received (or not), so that the base station may reclaim those scheduled resources in the case that the UE remains unaware of them. Methods for performing this signaling include, e.g., the use of HARQ-ACK codebooks (whether in a semi-static or dynamic manner), and aperiodic sounding reference signals (A-SRS). Embodiments involving such DCI received across multiple component carriers of different serving cells of the UE are contemplated. Acknowledgment signaling according to multi-PUSCH/multi-PDSCH subgroups, monitoring windows, acknowledgment signaling enablement/disablement, and the use of DCI to trigger acknowledgment signaling are also discussed.
