Abstract: This application discloses a wireless communication method, apparatus, and system, to ensure service quality of terminal communication in a non-standalone (NSA) networking architecture. The wireless communication method includes starting, by a terminal, radio resource control (RRC) connection establishment with a new radio (NR) cell based on an indication of a network device, and starting a timer based on a quantity of RRC connection establishment failures of the NR cell. The timer is set to a first duration. Within the first duration, when the network device indicates to the terminal to report measurement results of the NR cell and another cell, the terminal only reports the measurement result of the other cell, not the measurement result of the NR cell.

Abstract: This application describes a congestion control method and apparatus. In this application, a network device obtains time information of one or more congestion packets in a sent first data stream, where the one or more congestion packet carries a flag indicating a congestion notification. When the first data stream is congested, the network device obtains a first congestion notification packet based on the time information of the one or more congestion packets in the first data stream, where the first congestion notification packet notifies that a packet is congested beyond a first specified interval. The network device then sends the first congestion notification packet. According to the solutions in this application, a rate of a data stream can be prevented from being increased when the data stream is congested, and packet transmission efficiency is improved.

Abstract: Embodiments of this application provide a data transmission method, a communications device, and a storage medium, to reduce pressure caused by a quantity of cross connections between intermediate nodes to the intermediate nodes in a network. In an embodiment of this application, a first communications device obtains Q first code block streams, and obtains a to-be-sent second code block stream based on the Q first code block streams. Q downlink ports are in a one-to-one correspondence with the Q first code block streams, the Q downlink ports correspond to S code block groups, one code block in the Q first code block streams corresponds to one code block group, and the second code block stream obtained by the first communications device includes L code block sets; and for each of the L code block sets, the code block set includes K code blocks corresponding to each of the S code block groups. In the solutions provided in this embodiment of this application, code block streams are multiplexed at a code block granularity, so that a quantity of cross connections between intermediate nodes in a network can be reduced, thereby reducing pressure on network management and operation and maintenance.

Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A terminal device receives an identifier of a filtering protocol version from an access network device, and then sends first capability information of the terminal device to the access network device based on the filtering protocol version. In this method, the terminal device may report capability information based on the filtering protocol version sent by the access network device. Compared with a manner in which the terminal device directly reports the capability information, this method can effectively reduce a communication problem caused by mismatch between a protocol version supported by the terminal device and a protocol version supported by the access network device and/or a protocol version supported by a core network device.
