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: Embodiments of the present application provide a signal sending method, a device, and a system. A base station modulates, by using a first modulation scheme, signaling carried in a control channel, and modulates, by using a second modulation scheme, data carried in a traffic channel; and the base station sends, to UE, a signal obtained after modulation. In this way, the base station can independently select a modulation scheme for the control channel and the traffic channel, avoiding a case in which a modulation scheme used by the control channel and a modulation scheme used by the traffic channel must be the same, so that the base station can flexibly select a channel modulation scheme.

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.
