Abstract: An uplink data transmission method and an apparatus include or relate to a terminal device which determines, based on indication information of a network device, a time-frequency resource corresponding to a random access resource, or a part of a time frequency resource in the random access resource, to directly transmit uplink data. Configuration information of a time-frequency resource for random access may be reused for configuration information of the time-frequency resource, so that signaling overheads are reduced and a resource utilization is improved.

Abstract: A random access method and an apparatus are described that provide improved transmission efficiency of a response message based on the response message scheduled by a plurality of PDCCHs. A terminal device receives a first control channel resource set used to monitor a common physical downlink control channel PDCCH and a second control channel resource set used to monitor a specific PDCCH that are sent by a network device. The terminal device sends a first message to the network device, and the terminal device monitors a first search space corresponding to the first control channel resource set and a second search space corresponding to the second control channel resource set to receive at least one of the common PDCCH and the specific PDCCH, to schedule a PDSCH that carries a response message of the first message.

Abstract: Embodiments of this application provide a data transmission method and apparatus and a storage medium. The method includes: After obtaining a first identifier and a second identifier that uniquely identify a first device, the first device scrambles, by using the first identifier, checked data obtained through CRC check. After performing channel coding on to-be-transmitted data and scrambled checked data, the first device scrambles, by using the second identifier, coded data obtained through channel coding, and finally sends scrambled data. In this way, after receiving the scrambled data, a second device may perform descrambling by using the second identifier, and then perform CRC check, to determine whether the received data is correct and determine the first identifier of the first device.

Abstract: This application provides example scrambling-based data transmission methods and apparatuses. A scrambling manner is determined based on a sending waveform. The scrambling manner can include frequency domain scrambling, time domain scrambling, or time-frequency domain scrambling. To-be-scrambled data can be scrambled based on the scrambling manner, to obtain scrambled output data. The scrambled output data can be sent. The sending waveform can be a discrete Fourier transform spreading orthogonal frequency division multiplexing (DFT-s-OFDM) waveform or a cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) waveform.

Abstract: This application provides a resource configuration method and a communications apparatus. The method includes: receiving resource configuration information sent by a network device, where the resource configuration information includes at least one of the following: indication information used to indicate a time domain period or indication information used to indicate a transmission occasion TO determining manner, and the TO determining manner includes a first TO determining manner or a second TO determining manner; and determining, based on the resource configuration information, time domain positions of N TOs within the time domain period. Therefore, a terminal device may determine, based on the resource configuration information, the time domain positions of the N TOs within the time domain period, so that the terminal device repeatedly sends uplink data on the N TOs, improving data transmission reliability.
