Abstract: A signal generation method is disclosed, to enhance an anti-interference capability and a coverage area of a signal. The method includes: A first device obtains a first signal based on transmission information through channel encoding, where the transmission information includes information that the first device needs to send to a second device; the first device generates a second signal based on the first signal through repetition or frequency spread transformation; the first device generates a third signal based on the second signal through linear encoding; and the first device generates a target signal based on the third signal through signal modulation, where the target signal is sent to the second device. Associated devices are also described.

Abstract: A communication method and device. The method includes: inventory indication information sent by a network device to a terminal device includes information for determining a target terminal device. The inventory indication information indicates that the network device selects the target terminal device to initiate a random access request, or the inventory indication information indicates that the network device supports the target terminal device in initiating a random access request. In this way, the network device may select, based on target terminal devices of different types, or target terminal devices having different capabilities, a target device to perform random access, thereby improving random access efficiency of a second device and performance of subsequent data transmission of the target terminal device.

Abstract: A data transmission method and a communication apparatus. A first device may determine a second sequence, where the second sequence is obtained based on a base sequence and a first mask, and the first mask corresponds to a first encoding scheme. The first device sends the second sequence and a first sequence, where the first sequence includes a first encoded bit sequence obtained by encoding an information bit sequence based on the first encoding scheme, the first encoded bit sequence includes N bits, and N is a positive integer. The second device receives the second sequence and the first sequence from the first device and processes the received first encoded bit sequence by using a decoding scheme corresponding to the first encoding scheme. This manner is applicable to long-distance data transmission and may reduce missed detection and false detection of the first encoded bit sequence.

Abstract: This application provides resource allocation methods and apparatuses. In an implementation, a method includes: receiving, by a first apparatus from a second apparatus, a first index value in a first index value set that comprises a plurality of index values, each index value corresponds to a combination of values of a parameter in a parameter group that comprises a plurality of parameters, the first index value corresponds to a first frequency domain resource; and sending, by the first apparatus, uplink information on the first frequency domain resource.
