Abstract:
1. A method for transmitting a control signal and a reference signal by a base station, the method comprising the steps of: configuring a first set of frequency resource blocks (RBs) and a second set of the frequency RBs, wherein each of the frequency RBs includes resource elements (REs); transmitting, to a user equipment (UE), the control signal over a first number of symbols in a transmission time interval (TTI) and over a first number of the REs included either in the first set of the frequency RBs or in the second set of the frequency RBs; and transmitting, to the UE, the reference signal over a second number of symbols in the TTI and over a second number of the REs included either in the first set of the frequency RBs or in the second set of the frequency RBs, wherein the first set of the frequency RBs is indicated to the UE by higher layer signaling or by broadcast signaling, and the second set of the frequency RBs is indicated to the UE by a physical control format indicator channel (PCFICH), wherein the first number of symbols and the second number of symbols are included in a data region of a subframe, and wherein the reference signal is a demodulation reference signal (DMRS).
