Abstract: In accordance with implementations, a device determines an AI/ML model training capability of the device. The AI/ML model training capability indicates a capability of the device to contributively participate in an AI/ML model training process with at least a second device in a wireless communication network. The AI/ML model training capability is determined based on at least one of a current processing capability of the device, a current volume of training data available for the AI/ML model training process at the device, or a sensing capacity of the device to collect the training data for the AI/ML model training process. The device then transmits the AI/ML model training capability to the second device.

Abstract: Embodiments of this application provide a data transmission method, a network device, and a terminal device. The method may include detecting, by a network device, a first signal in an uplink signal. The method may also include determining, by the network device, a signal structure of the uplink signal based on a result of detecting the first signal. Furthermore, the method may include receiving, by the network device, the uplink signal based on the signal structure, and/or responding to the uplink signal based on the signal structure. According to the data transmission method in the embodiments of this application, before receiving data, the network device can determine the signal structure, used by the terminal device, of the uplink signal, and then use a corresponding receiving method to avoid complexity and a reliability risk that are caused by completely blind detection performed by the network device.

Abstract: Methods and apparatuses are disclosed for semi-persistent scheduling and configured grant transmission configurations. An example method, which is performed by a communication device, includes the steps of: transmitting, to a user equipment (UE), a radio resource control (RRC) signal or activation downlink control information (DCI) signal for semi-persistent scheduling (SPS) or configured grant (CG) transmission configuration; and transmitting, to the UE, a physical layer control signal comprising an indication of one or more parameters for SPS or CG transmission.

Abstract: In some wireless communication scenarios, a user equipment (UE) may perform sensing and feedback measurements or results, which a transmit-and-receive point (TRP) may then use to determine information about objects and/or conditions in the vicinity of the TRP. However, the UE might be in a power-saving state when the TRP requires the UE to perform the sensing. In some embodiments, the UE can be triggered to perform sensing as part of the paging information transmitted from the TRP, e.g. in the paging downlink control information (DCI) and/or in the paging message or in another message scheduled by the DCI.

Abstract: Current frame structures in Long-Term Evolution (LTE) and New Radio (NR) are not designed to accommodate full duplex (FD) communication. Embodiments are disclosed in which frame structures are provided that support FD communication and frequency division duplex (FDD) communication and time division duplex (TDD) communication. In some embodiments, there is defined two separate and independent frame structures: a frame structure for reception (e.g. a downlink frame structure) and a frame structure for transmission (e.g. an uplink frame structure).

Abstract: Different filtered-orthogonal frequency division multiplexing (f-OFDM) frame formats may be used to achieve the spectrum flexibility. F-OFDM waveforms are generated by applying a pulse shaping digital filter to an orthogonal frequency division multiplexed (OFDM) signal. Different frame formats may be used to carry different traffic types as well as to adapt to characteristics of the channel, transmitter, receiver, or serving cell. The different frame formats may utilize different sub-carrier (SC) spacings and/or cyclic prefix (CP) lengths. In some embodiments, the different frame formats also utilize different symbol durations and/or transmission time interval (TTI) lengths.
