Patent ID: 8817739

Claim:
A method for performing uplink transmission in a time domain transmission unit, the method comprising: receiving, by a user equipment from a base station, hopping-mode information indicating whether a frequency hopping is an inter-slot hopping or an inter-subframe hopping; and performing, by the user equipment, the uplink transmission using a resource block in the time domain transmission unit, wherein the resource block for the uplink transmission is given using a subband hopping based on the following Equation: an index of the resource block=(a reference index+a(t)*N RB sb )mod N RB sb ·N sb where “N sb ” is a number of subbands, “N RB sb ” is a number of resource blocks for each subband, “a(t)” is a random integer and “t” is an index of the time domain transmission unit, wherein: the index of the time domain transmission unit is an index of a slot when the hopping-mode information indicates that the frequency hopping is the inter-slot hopping; and the index of the time domain transmission unit is an index of a subframe when the hopping-mode information indicates that the frequency hopping is the inter-subframe hopping.
