A method for generating continuous resource allocation signaling comprises: a sender determines a value of the total number of resource blocks NRB in a system according to the total resource number in the system and determines, according to the amount and location of the total resources occupied by the continuous resources allocated to the target user equipment, the number of continuous resource blocks allocated to the user equipment LCRBs and the value of the index number of the starting resource block RBstart in the continuous resource blocks allocated to the user equipment; the sender compares LCRBs−1 with └NRB/2┘ to compute the value RIV of the resource allocation signaling of the user equipment; if the LCRBs−1 is greater than the └NRB/2┘, then the RIV is NRB(NRB−LCRBs+1)±(NRB−1−RBstart); else the RIV is NRB(LCRBs−1)+RBstart; and the resource allocation signaling of the target user equipment is generated according to RIV and transmitted. An apparatus for generating continuous resource allocation signaling, and a method and an apparatus for parsing continuous resource allocation signaling, are also disclosed. The present invention ensures that under any resource allocation situation the overhead for resource allocation signaling is always
