Abstract:
1. In a communication system in which User Equipments (UEs) receive Downlink Control Information (DCI) formats transmitted through respective Physical Downlink Control Channels (PDCCHs) from a base station over a transmission time interval, a method for a UE to transmit signals in a Physical Uplink Shared Channel (PUSCH) over a communication system operating bandwidth in response to reception of a DCI format, the method comprising the steps of: determining first frequency resources for transmission of the signals in the PUSCH from second frequency resources indicated by a first DCI format; determining values of all other parameters for the transmission of the signals in the PUSCH by other signaling exclusive of the first DCI format; and transmitting the signals in the PUSCH using the first frequency resources, wherein the size of the first DCI format is same that of a second DCI format for Scheduling PCH (Paging Channel), RACH (Random Access Channel) Response or SIB (Secondary Information Block) Transmissions, and wherein the all other parameters comprise the DCI Format Indication Flag, Modulation-Coding Scheme (MCS), New Data Indicator (NDI), Transmission Power Control (TPC), Cyclic Shift Indicator (CSI), Frequency Hopping (FH), CQI Request, Resource Allocation Type and Zero Padding.
