Aspects of the disclosure relate to wireless communication using channel state information (CSI) correlation information for determining the validity of a CSI report. A user equipment (UE) can determine the CSI correlation information based on reference signal resources scheduled for measuring CSI and interference on a channel between the UE and a network entity. In some aspects, the CSI correlation information can be determined based on channel correlation information and/or interference correlation information.

A method performed by a wireless communication device includes determining whether to transmit a first Sidelink Synchronization Signal (SLSS) according to a priority parameter when an occasion of the first SLSS collides with a Physical Sidelink Feedback Channel (PSFCH) that carries Sidelink Feedback Control Information (SFCI). The priority parameter is associated with a Physical Sidelink Shared Channel (PSSCH) that corresponds to the PSFCH.

A configuration information sending method and an apparatus is applied to fields such as user cooperation, user relay, and an internet of vehicles. First configuration information is sent to a first user group, where the first configuration information indicates at least one resource element, the first user group includes a first terminal apparatus and a second terminal apparatus, and the first terminal apparatus is configured to assist in information transmission between a first network apparatus and the second terminal apparatus. The first network apparatus sends first downlink control information to the first user group, where the first downlink control information indicates a first resource element in the at least one resource element and a first time-frequency resource, and the first time-frequency resource belongs to the first resource element.

Disclosed is a method for determining hybrid automatic repeat request process information. The method comprises: a first terminal device determining, according to a first hybrid automatic repeat request (HARQ) process identifier indicated by a network device, a second HARQ process identifier corresponding to a sidelink transmission. Further disclosed are a terminal device and a storage medium.

Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) engages in a downlink positioning session, a sidelink positioning session, or both with one or more first network entities, and transmits at least one positioning capability report to one or more second network entities, the at least one positioning capability report including one or more parameters indicating joint downlink and sidelink capabilities of the UE to process both downlink positioning reference signals (DL-PRS) and sidelink positioning reference signals (SL-PRS).

A method for performing wireless communication by a first device includes: receiving, from a base station, downlink control information (DCI) for scheduling a sidelink (SL) resource, the DCI including information related to time between a physical sidelink feedback channel (PSFCH) resource and a physical uplink control channel (PUCCH) resource and information related to the PUCCH resource; transmitting, to a second device, a plurality of physical sidelink control channels (PSCCHs) and a plurality of physical sidelink shared channels (PSSCHs) based on the DCI; determining a plurality of PSFCH resources based on an index of a slot and a sub channel related to the plurality of PSSCHs and a source ID of the first device; receiving a plurality of pieces of SL HARQ feedback related to the plurality of PSSCHs; and transmitting, to the base station, one piece of SL hybrid automatic repeat request (HARQ) feedback on one PUCCH resource.

A wireless communication method and a device are provided. The method includes: obtaining, by a terminal device, sidelink configuration information for a sidelink licensed carrier and a sidelink unlicensed carrier; and transmitting and/or receiving, by the terminal device, sidelink data on the sidelink licensed carrier and the sidelink unlicensed carrier according to the sidelink configuration information. By obtaining the sidelink configuration information for the sidelink licensed carrier and the sidelink unlicensed carrier, the sidelink licensed carrier and the sidelink unlicensed carrier can be managed coordinately. That is, with the sidelink licensed carrier, the access delay of the unlicensed carrier and the reliability of data transmission on the sidelink unlicensed carrier become controllable, thereby reducing the access delay and improving the reliability of data transmission. Accordingly, the QoS requirement of the service data can be met.

Disclosed are a method and an apparatus for transmitting an uplink frame in a wireless LAN. The method for transmitting an uplink frame in a wireless LAN may comprise: a step in which an STA receives a downlink PPDU from an AP through a downlink dedicated channel; a step in which the STA performs a first channel switching from the downlink dedicated channel to a general channel on the basis of information about TXOP duration for transmitting the downlink PPDU if STA indication information included in the received downlink PPDU does not indicate the STA and a pending uplink frame is present in the STA; a step in which the STA performs a channel access for transmitting the uplink frame via the general channel on a time resource corresponding to the TXOP duration; and a step in which the STA performs a second channel switching from the general channel to the downlink dedicated channel on the basis of the information about TXOP duration.

The UE also includes a transmitter configured to transmit the sidelink transmission in the different periodicity according to the at least one of the plurality of SPS configurations. The BS includes a controller configured to select at least one SPS configuration among a plurality of SPS configurations for a UE. Each of the SPS configurations configures the UE with a different periodicity of a sidelink transmission to be transmitted to another UE. The BS also includes a transmitter configured to transmit the selected at least one SPS configuration to the UE.
