Abstract: A data transmission method includes obtaining a first sequence, determining a first element in the first sequence, and performing data transmission with a network device in one frequency hopping cycle based on a frequency corresponding to an element in the first sequence. The first sequence includes Q elements that correspond to Q different frequencies. Q is a positive integer greater than 1. A first frequency corresponding to a first terminal device at a first frequency hopping moment, and corresponding to the first element. A second frequency corresponding to the first terminal device at an ith frequency hopping moment, and corresponding to a second element obtained by cyclically moving from the first element in a left or right direction for i−1 times according to a specified rule, and i is a positive integer from 2 to M, and M is a positive integer greater than or equal to 2.

Abstract: A user equipment receives first indication information from a network device, where the first indication information indicates a status of each resource block group in a grant-free GF resource, the GF resource includes one or more resource block groups, each resource block group includes at least one resource block, and a status of one resource block group includes a congested state or an idle state. The user equipment performs first communication with the network device by using a first resource, where the first resource is determined based on the first indication information, and the first resource is at least one resource block group in the GF resource.

Abstract: This application relates to the field of wireless communication technologies. A terminal device receives configuration information, which indicates that one first combination is mapped to a plurality of downlink reference signals, and one first combination is mapped to a plurality of second combinations. The terminal device then determines a mapping relationship between a first combination and downlink reference signals, a mapping relationship between a first combination and second combinations, and a mapping relationship between second combinations and downlink reference signals based on the configuration information. Next, a first preamble is sent on a first RO included in a first combination, and a first uplink reference signal is sent on a first PO included in a second combination. The selected first combination has a mapping relationship with the selected second combination. A selected downlink reference signal group is indicated by the selected first combination.

Abstract: A communication method and apparatus to prevent a network device from frequently configuring signatures for a terminal device, and to reduce signaling overheads and power consumption of the network device and the terminal device. A terminal device determines a first downlink signal from a plurality of downlink signals. The terminal device determines, based on the first downlink signal, at least one signature from a plurality of signatures that have a mapping relationship or an association relationship with the plurality of downlink signals. The terminal device sends data by using the at least one signature.

Abstract: Embodiments of this application relate to the field of wireless communication technologies, including the field of Wi-Fi technologies, and provide a pilot symbol transmission method and an apparatus, to reduce a possibility that pilots sent by different users in a network collide. In the method, a terminal device may send a codeword, and the codeword may include a pilot symbol and a data symbol. The pilot symbol may include a non-zero pilot symbol and a zero pilot symbol, and the data symbol may include a non-zero data symbol and a zero data symbol. According to the foregoing solutions, the pilot symbol sent by the terminal device may include the non-zero pilot symbol and the zero pilot symbol, so that the pilot symbol sent by the terminal device is sparse.
