摘要： Embodiments of this application provide a communication processing method for a resource request and a related device. In the communication processing method, a terminal side device sends K uplink resource requests on K (K is an integer greater than or equal to 2) uplink channel resources in a transmission time unit (for example, 1 millisecond) to request an uplink resource used for uplink transmission, where cyclic shifts of a code division multiplexing (CDM) sequence used to send the K uplink resource requests on the K uplink channel resources are specific to the terminal side device, or a value of K is specific to the terminal side device, or a combination of the cyclic shifts and K is specific to the terminal side device.

摘要： Disclosed is a reference signal transmission method and a device. The method includes converting, by a sending device, a frequency domain reference signal from frequency domain to time domain, to generate a time domain reference signal. The frequency domain reference signal includes a reference signal sequence mapped to a frequency domain resource. The reference signal sequence is determined based on a Zadoff-Chu (ZC) sequence, and a length value of the ZC sequence is selected from at least two length values. The method includes sending, by the sending device, the time domain reference signal. According to the reference signal transmission method, one ZC sequence is selected from at least two ZC sequences with different lengths to generate the reference signal sequence, so that the generated reference signal sequence is characterized by a low PAPR and an low RCM, and is used to generate a reference signal, to improve data transmission performance.

摘要： A data sending apparatus includes a processor and a transceiver. The processor is configured to generate K first frequency-domain data streams, wherein a kth first frequency-domain data stream of the K first frequency-domain data streams is determined by performing preprocessing on a kth first modulated data stream, and the preprocessing includes at least a Fourier transform, a cyclic extension, or a phase rotation. The processor is further configured to map the K first frequency-domain data streams to frequency-domain resources to generate a time-domain symbol, and the transceiver is configured to send the time-domain symbol.

摘要： A method and an apparatus for switching a cell state are provided, and relate to the field of communication technologies. The method includes: A terminal device receives a first instruction from a network device, and switches a serving cell state based on the first instruction. The first instruction indicates to switch the serving cell state of the terminal device to or from a first state. When the serving cell state is the first state, a downlink carrier of a serving cell supports downlink communication, and an uplink carrier of the serving cell does not support uplink communication.
