This provides a search space group indication and further provides a method of search space group switching.

Apparatuses, methods, and systems are disclosed for transmitting SL CSI using an uplink channel. One apparatus includes a transceiver that receives a first SL-CSI value from a RX UE via one of a plurality of unicast links. The apparatus includes a processor that generates a SL-CSI report comprising the first SL-CSI value, wherein the first SL-CSI value is tagged with an identifier that identifies the RX UE. The processor controls the transceiver to transmit the SL-CSI report using an uplink channel.

Provided are a data transmission method and apparatus and a storage medium. The data transmission method includes that a first communication node succeeds in channel contention on a first channel; the first communication node performs channel detection on a second channel within the preset duration before the sending moment of the first channel to acquire a detection result; and the first communication node sends a notification frame to a second communication node on the second channel in response to the detection result being idle, where the notification frame is used for instructing the second communication node not to send data on the second channel.

The present disclosure provides a method for transmitting and receiving a sidelink positioning reference signal and a terminal. The method includes: when a resource occupied by the sidelink positioning reference signal collides with a resource occupied by at least one type of information in a first information set, not transmitting the S-PRS on the collided resource, wherein the first information set includes: at least one of a sidelink physical channel, a sidelink reference signal, a sidelink synchronization signal, a sidelink synchronization signal block, an automatic gain control information and a guard period information.

Disclosure discloses a method and a device in a node for wireless communications.
