A METHOD OF PROVIDING CONTROL INFORMATION FOR USER EQUIPMENT IN AN LTE COMMUNICATION SYSTEM

摘要

There is provided a method of providing control information for UEs (150) in data communication with an eNodeB (110) over a LTE wireless communication system (100). This method includes: encoding at least one E-PDCCH that includes control information for configuring the UEs (150) to communicate data with the eNodeB (110) over the LTE wireless communication system (100); mapping the at least one E-PDCCH on at least one allocated pair of PRBs according to an E-CCE structure including a variable number of REGs; varying the number of REGs in an E-CCE structure to optimise the channel capacity utilisation for the E-PDCCH mapping; and communicating the at least one E-PDCCH mapped onto the at least one allocated pair of PRBs to the UEs (150) so that the UEs (150) can be configured to communicate the data over the LTE wireless communication system (100) based on the control information.
