摘要： This application provides an information transmission method and a communication apparatus. The method includes: A terminal device determines a first time resource, where the first time resource includes at least one time unit, and the first time resource is for sending a first reference signal RS. The terminal device determines a second time resource, where the second time resource includes at least one time unit, and the second time resource is for sending a second RS. There are K time units between the first time resource and the second time resource, and K is a natural number. K falls within a first value range, and a guard period GP between the first time resource and the second time resource includes a first quantity of time units. Alternatively, K falls within a second value range, and a GP does not exist. The terminal device sends the first RS on the first time resource, and sends the second RS on the second time resource. According to the foregoing method, in this application, a GP between different RSs is defined. This improves scheduling flexibility of a network device.

摘要： This application provides a reference signal transmission method and a communication apparatus. In the reference signal transmission method, a second time unit is a time unit indicated by a time offset indicator n in valid uplink transmission time units or valid downlink transmission time units starting from a first time unit. The first time unit is used to receive first information. The first information is used to trigger a terminal device to transmit a reference signal. The second time unit is used by the terminal device to transmit the reference signal. Compared with a manner in which the time offset indicator n indicates a time offset between the first time unit and the second time unit, this implementation helps improve flexibility of selecting the first time unit, and reduce a quantity of bits required by the time offset indicator n.

摘要： This application relates to a sequence detection method and a device. In embodiments of this application, K candidate frequency domain root sequences may be first filtered based on a differentiation result of received first sequence and differentiation results of candidate frequency domain root sequences, and a candidate frequency domain root sequence to which the first sequence actually corresponds only needs to be determined based on the first sequence and the K candidate frequency domain root sequences. For example, there are U candidate frequency domain root sequences. In this case, a current calculation amount is calculation of U * C s cross correlation values. In embodiments of this application, a calculation amount is calculation of only L * U + K * C s , where C s represents a quantity of sampled time domain cyclic shift values, and L represents a quantity of differentiation granularities. If K is less than U, the calculation amount required in embodiments of this application is far less than the calculation amount required for current sequence detection. Therefore, the technical solution in embodiments of this application can greatly reduce detection complexity of a signal receive end, and improve detection efficiency.

摘要： This application provides a reference signal mapping method and an apparatus, to resolve a problem that a quantity of supported ports and a quantity of supported transmitted streams are excessively small due to an existing reference signal mapping rule in which a fixed quantity of time-frequency resources are used for mapping. This improves system performance and a capacity, and can be applied to MIMO systems such as 5G and V2X. The method includes: determining a plurality of resource groups and a plurality of port groups in a time-frequency unit based on a preset or configured size of a first frequency domain unit and a preset or configured first port index, and mapping, based on a port group to which a port corresponding to the first port index belongs, a reference signal corresponding to the port to a resource group corresponding to the port group in the time-frequency unit.

摘要： This application provides a sequence-based signal processing method and apparatus. A sequence used for sending a signal on a PUSCH is determined. The sequence is a sequence { x n } including N elements, x n is an element in the sequence { x n }, and the determined sequence { x n } is a sequence satisfying a preset condition. Then, a first signal is generated and sent. By using the determined sequence, when a signal is sent on the PUSCH, relatively good sequence frequency domain flatness can be maintained, and a relatively low PAPR value and a relatively low cross-correlation between sequences can be maintained, thereby satisfying a communications application environment in which a signal is sent on the PUSCH, especially an NR system scenario or an NR similar scenario.
