A terminal includes a reception unit that receives a request for channel state information from another terminal, a control unit that identifies a reference signal and a predetermined period, to be used for measurement, based on the request and receives one or more shared channels including the reference signal to measure the channel state information, and a transmission unit that transmits a report associated with the measured channel state information to the other terminal within the predetermined period.

A resource configuration indication method includes that: the terminal device sends time domain resource indication information, wherein the time domain resource indication information is configured to indicate a transmission period and the number of time domain resource units.

A system may receive published messages over an uplink channel. The system may, via channel control logic (CCL), delegate the messages to one or more subject-domain downlink channels (SDDCHs). The CCL may determine to create new SDDCHs to facilitate accurate placement of messages within defined subject-domains corresponding to the various SDDCHs.

This application provides a data transmission method and an apparatus, and may be applied to fields such as user equipment cooperation, sidelink relay, user relay, and internet of vehicles. A first terminal apparatus receives at least two pieces of downlink control information from a first network apparatus in a first slot, where the at least two pieces of downlink control information include first downlink control information and second downlink control information, the first downlink control information is used to indicate a first sidelink resource used by the first terminal apparatus to send first sidelink information to a second terminal apparatus, and the second downlink control information is used to indicate a second sidelink resource used by the first terminal apparatus to send second sidelink information to a third terminal apparatus.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive, from a first wireless device, an uplink communication using a first guard interval. The IAB may receive, from a second wireless device, a downlink communication using a second guard interval, a second length of the second guard interval being different from a first length of the first guard interval. The IAB may process the uplink communication and the downlink communication in a same fast Fourier transform window. Numerous other aspects are described.

Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may generate statistical modeling of sensing outcomes (e.g., may identify one or more measurement statistics), and may transmit values that are quantized based on the one or more measurement statistics. Measurement statistics may include one or more of mean and variance of sensing results (e.g., channel quality measurements such as signal to interference ratio (SIR)), auto-correlation of measurements or measurement statistics over time, auto-covariance, or the like. In some examples, a UE may incorporate channel measurement statistics into a waveform (e.g., the coordination report) or otherwise compress the measurements. The UE may measure its own self-interference, and may indicate (e.g., in the coordination message) resource availability that reflects the measured self-interference. A receiving UE may use the coordination message to schedule subsequent sidelink communications (e.g., with the transmitting UE or with other UEs).

Methods, systems, and devices for wireless communications are described. In some examples, a base station may send signaling to multiple user equipments (UEs) indicating for the UEs to switch to a radio frequency bandwidth. The UEs may operate according to a reduced set of communication operations in accordance with the radio frequency bandwidth. For example, the UEs may refrain from monitoring one or more channels, may not transmit on one or more channels, or the like. The UEs may switch out of the radio frequency bandwidth based on a trigger event, such as a timer expiring, receiving an indication in a downlink control information (DCI) message, or the like.

Methods, systems, and devices for wireless communications are described. A sidelink message may be scheduled for a UE during a first short transmission time interval (TTI). The first short TTI and a second short TTI for transmitting a sidelink feedback message corresponding to the sidelink message may both be shorter in duration than a another, longer type of TTI. The UE may transmit automatic gain control information in a first symbol period of the second TTI, transmit the sidelink feedback message in a second symbol period of the second TTI (after the first symbol period of the second TTI), and switch from operating in a transmitting mode to operating in a receiving mode during a third symbol period of the second TTI (after the second symbol period of the second TTI).

The present disclosure relates to retuning methods and apparatus. One example method includes determining a first resource and a second resource, where the first resource is used to receive a physical downlink control channel (PDCCH) or physical downlink shared channel (PDSCH), the first resource is determined based on a first frequency domain resource and M consecutive symbols of a downlink pilot timeslot in a special subframe, the second resource is used to send a sounding reference signal (SRS), the second resource is determined based on a second frequency domain resource and an uplink pilot timeslot in the special subframe, all or a part of the second frequency domain resource is not in the first frequency domain resource, and determining, in the last N consecutive symbols of the downlink pilot timeslot, a guard period for retuning.

Embodiments of the disclosure generally relate to resource configuration. A network device configures, based on an access mode of a terminal device, an information transmission pattern for the terminal device from a first resource set associated with a MOMA mode and a second resource set associated with a NOMA mode.
