    Abstract: Methods and apparatus related to pulse shaped and overlapped reference signals are disclosed. Signaling that indicates information associated with a length of a base sequence and a length of a cyclic rotation is communicated between a first communication device and a second communication device in a wireless communication network. A DMRS is also communicated in the wireless communication network. The DMRS comprises a DMRS sequence of a target length, and the DMRS sequence comprises the base sequence cyclically rotated by the length of the cyclic rotation. Cyclic extension is also applied a base sequence in some embodiments.

    Abstract: This application provides a symbol processing method and apparatus. The method includes: A transmitting end generates a first transmit symbol and a second transmit symbol. A length of a cyclic prefix of the first transmit symbol is greater than a length of a cyclic prefix that corresponds to a subcarrier spacing of the first transmit symbol. The transmitting end sends the first transmit symbol and the second transmit symbol. The first transmit symbol and the second transmit symbol are consecutive in time domain. The first transmit symbol is located after the second transmit symbol. The first transmit symbol is a symbol that carries a reference signal, and the second transmit symbol is a symbol that carries a data signal.

    Abstract: Embodiments of the present invention disclose a communication method and a device. The method is applied to any terminal in a positioning system that includes one or more network devices and one or more terminals. The method includes: A terminal receives a measurement indication from a network device. The terminal receives reference signals from the network device, and measures the reference signals based on the measurement indication, where the reference signals are used for positioning measurement. The terminal sends one or more groups of measurement results to the network device, where reference signals corresponding to each group of measurement results have an association relationship, and the association relationship includes that each group of measurement results is measurement results of a same receive beam. According to the embodiments of the present invention, positioning efficiency can be improved.

    Abstract: This application provides a symbol processing method and apparatus. The method includes: obtaining a plurality of complex-valued symbols; dividing the plurality of complex-valued symbols into a plurality of sets, where each set corresponds to one transmitted symbol; and performing a copy operation on the plurality of sets, so that two sets corresponding to two transmitted symbols that are consecutive in time domain have some same complex-valued symbols. By enabling two sets corresponding to two transmitted symbols that are consecutive in time domain to have some same complex-valued symbols, a guard interval between symbols can be flexibly configured when a cyclic prefix length is fixed.
