摘要： Provided are a wireless communication method, a terminal device, and a network device. The method includes determining, by a terminal device based on a first timer and a first counter, whether a persistent listen before talk (LBT) failure event occurs on a first resource pool. The first resource pool is a resource pool associated with a first transmission resource. The first transmission resource is a transmission resource used by the terminal device for sidelink transmission. The first timer is a timer corresponding to the first resource pool. The first counter is configured to count the number of LBT failures occurring on the first resource pool during operation of the first timer.

摘要： Provided are an information processing method, a device and a storage medium, achieving sidelink data retransmission. The method includes: a transmitting terminal using an unlicensed spectrum to send data, to a receiving terminal on an HARQ process. When the data needs to be retransmitted, the transmitting terminal generates indication information and sends the indication information to a network device, such that the network device learns of data transmission on the HARQ process to determine whether a new radio resource needs to be configured for data retransmission. In the method, the indication information sent by the transmitting terminal indicates the data transmission on at least one HARQ process, thereby solving the problem that since the transmitting terminal uses the unlicensed spectrum to send the data, the network device is unable to learn of the date transmission of each HARQ process. The method improves the data transmission efficiency of a communication system.

摘要： A method and apparatus for information transmission, a method and apparatus for information reception, devices, and a storage medium are provided in the disclosure. The disclosure relates to the field of mobile communication technology. The method for information transmission is applied to a second node in a mobile communication system. The method includes the following. Transmit information of a first model to a first node in the mobile communication system, where the information of the first model is used to set up the first model in the first node. The first model is one of an encoding model and a decoding model matched with the encoding model. The second node in the mobile communication system transmits the information of the first model to the first node, so that an encoding model and a decoding model matched with the encoding model can be provided for the first node and the second node, respectively, thereby implementing information exchange in the mobile communication system.

摘要： Provided in the embodiments of the present application are a wireless communication method, a terminal device, and a network device, the method comprising: a terminal device acquires CG configuration information; and, on the basis of the CG configuration information, the terminal device implements sidelink transmission, the CG configuration information comprising: information of a plurality of CG resource sets in one CG resource period. Thus, there is no need for the network device to dynamically schedule resources for initial data transmission or re-transmission on the sidelink, so that there is no need to introduce additional latency, ensuring prompt acquisition of retransmission resources.
