Abstract: A data sending method, a related device, and a system are described. The method includes sending, by a network device, resource location information of a first reference signal and a physical channel to a terminal, where a first time-frequency resource on which the first reference signal is mapped overlaps a second time-frequency resource corresponding to the physical channel. An overlapping resource is not used to transmit the physical channel, and a third time-frequency resource in the second time-frequency resource other than the overlapping resource is used to transmit the physical channel. Alternatively, an overlapping resource is used to send a second reference signal; or an overlapping region is used to send a second reference signal, where the terminal skips sending the first reference signal, and the second reference signal is orthogonal to the first reference signal.

Abstract: The present invention provides a signal sending apparatus, a signal detection apparatus, a signal sending and detection system, a signal sending method, and a signal detection method. The apparatus determines a time unit that is in each time window and that is used to transmit a synchronization signal, and transmits the synchronization signal in the determined time unit in each time window. Therefore, a synchronization signal is always located in a time unit that has a fixed location in each time window, so that a device at a receive end needs to perform detection only in a fixed time unit in each time window, thereby reducing complexity of designing and detecting the synchronization signal.

Abstract: In a system and method of control channel transmission in the communications field, REs, except those used for transmitting a DMRS, are grouped in each physical resource block pair of L physical resource block pairs. The L physical resource block pairs are determined to be used to transmit a control channel into N eREGs. The number of valid REs are calculated except other overheads in each eREG of the N eREGs. Each of the eCCEs are mapped onto M eREGs according to the number of valid REs included in each eREG of the N eREGs of each physical resource block pair. The eCCE is sent in the REs included in the eREG.

Abstract: The present disclosure includes example resource selection methods and apparatuses. The example method includes configuring a CSI process for a second device, where the CSI process corresponds to configuration information of K reference signal resources or configuration information of K reference signal antenna port groups. A reference signal is sent to the second device according to the configuration information corresponding to the CSI process, so that the second device obtains a corresponding channel quality measurement result by measuring the reference signal, where the channel quality measurement result includes a precoding matrix indicator (PMI). The PMI is used to indicate a serial number of a precoding matrix selected by the second device, and the selected precoding matrix is a matrix in a preset precoding matrix set, where the preset precoding matrix set is determined according to K and a quantity T of beams to be selected.
