Disclosed are a data transmission method and apparatus, which are used for realizing low-delay and high-reliability transmission of data in a new radio (NR) system. The method comprises: determining an actual transmission opportunity in a transmission period according to a notification of a network side, and determining a first transmission opportunity on the basis of the actual transmission opportunity, wherein there are T valid transmission opportunities between the first transmission opportunity and a first moment, the valid transmission opportunities include an actual transmission opportunity with an RV of zero, and the first moment is before the end of the transmission period or before the start of a period of a second configuration authorization configuration; when data is ready before the first transmission opportunity and after the second transmission opportunity, starting data transmission at the first transmission opportunity, wherein the second transmission opportunity is the actual transmission opportunity before the first transmission opportunity; and when the data is ready after the first transmission opportunity, starting the data transmission in the next period. Therefore, a valid starting position may be determined according to a received signaling indication.

An information transmission method includes sending, by a terminal, second information and uplink data. The uplink data is sent in a second access mode. The second information indicates a first access mode. The first access mode is useable by the terminal to send the uplink data before the terminal sends the uplink data in the second access mode.

This application discloses a method and an apparatus for sending auxiliary information, a method and an apparatus for receiving auxiliary information, a terminal, and a network side device, and belongs to the field of communication technologies. The method for sending auxiliary information includes: sending auxiliary information for a target configuration to a network side device, where the target configuration is a configuration related to transmission of a preconfigured physical uplink shared channel PUSCH resource.

Various aspects of the present disclosure relate to generating a notification that instructs a user equipment (UE) to perform a configured grant-small data transmission (CG-SDT) action to cause CG-SDT resources of the UE to be released. A base station generates a notification with an instruction to perform a CG-SDT action and communicates the notification to a UE. The UE receives the instruction and performs the CG-SDT action to release CG-SDT resources allocated to the UE while the UE is in an inactive state.

An information multiplexing method and apparatus, and user equipment are provided. The method includes: in a case that time domain resources for an uplink data channel and at least one uplink control channel overlap, multiplexing at least one UCI onto the uplink data channel, and coding the at least one UCI based on type information of the at least one UCI, where the at least one UCI is UCI carried on the at least one uplink control channel.

A method for sidelink (SL) configured grant (CG) resource determination, a terminal device, and a storage medium are provided. The method for SL CG resource determination includes the following. A terminal device determines a time-domain resource for a first SL CG according to at least one of: a number of slots corresponding to a period of the first SL CG in a resource pool associated with the first SL CG and an offset in time domain of a target SL transmission resource in the first SL CG relative to a first SL transmission resource.

Methods, systems, and devices for sidelink configured grant skipping are described. In some examples, a first user equipment (UE) may receive, from a base station, an indication of periodic data resources for a plurality of sidelink data transmissions and an indication of negative scheduling request resources for the first UE to report a skipped sidelink data transmission associated with the plurality of sidelink data transmissions. In some examples, the first UE may transmit, to a second UE, an indication of the skipped sidelink data transmission and may transmit, to a base station, a negative scheduling request using the negative scheduling request resources, where the negative scheduling request may report the skipped data transmissions associated with the plurality of sidelink data transmissions.

Methods, systems, and devices for wireless communications are described. that support preconfigured uplink resources (PUR) in wireless communications. A base station may communicate that support for PUR is available, and may allocate PUR resources to a user equipment (UE) based on requests from the UE. The UE may receive an indication that the base station supports PUR, such as via a system information block (SIB), determine to request PUR, and transmit a PUR request message to the base station. A PUR response from the base station may indicate configuration, or reconfiguration of PUR allocation for the UE that may be used for uplink transmissions, or release of the PUR allocation.

The embodiments of the present disclosure provide a data communication method, a terminal device and a network device. The method includes: according to Configured Grant (CG) resource configuration information, determining, by a terminal device, a CG resource usage mode. The CG resource configuration information is sent by a network device.

Disclosed are a CG configuration method and apparatus, and a device and a storage medium, which relate to the field of communications. The method comprises: a network device configuring at least one CG for a terminal, wherein the at least one CG comprises at least one of a first-type CG and a second-type CG, and the first-type CG and/or the second-type CG is used for a shared spectrum access operation. By means of the present application, in an NR-U scenario, a breakthrough occurs in terms of the limitation that only a CG resource for an NR-U can be configured, and a network device configures at least one type of CG for the same UE, thereby improving the communication quality and success rate.
