CONTROL CHANNEL TRANSMISSION METHOD AND DEVICE

摘要

Embodiments of the present invention relate to the communications field and provide a control channel transmission method and apparatus, which can ensure a balance between actual sizes of eCCEs mapped from control channels, further ensure a performance balance when demodulating each eCCE, and reduce implementation complexity of a scheduler. The method includes: grouping REs except a DMRS in each physical resource block pair of L determined physical resource block pairs used to transmit a control channel into N eREGs, and calculating the number of valid REs except other overheads in each eREG of the N eREGs; and then mapping each of the eCCEs onto M eREGs according to the number of valid REs included in each eREG of the N eREGs of each physical resource block pair, and sending the eCCE by using the resource elements included in the eREG.
