Abstract  Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to resource allocation and physical transmission / reception of physical channels in a communication system using an OFDM scheme, and more particularly, to a resource allocation and transmission / reception method of a heterogeneous downlink control channel in consideration of frequency diversity. The present invention defines a set of rules for mapping different downlink physical channels defined in the LTE system, such as PCFICH, PHICH, and PDCCH, to mini control channel elements (mini-CCEs), which are physical resources. The mapping rules are defined such that one control channel is configured using mini-control channel elements that are separated on the frequency axis as much as possible in order to obtain frequency diversity gain without causing physical resources to collide with each other.


Resource mapping of a control channel is a process of arranging mini control channel element resources existing in two dimensions in one dimension by mini control channel element numbering rules and selecting resources of individual control channels according to resource mapping rules of physical channels. Is performed. In the resource mapping process of a physical channel, a physical channel having a largest number interval is selected to form a single physical channel.As the number interval is larger, the mini-control channel element is numbered so that the resource is separated on the frequency axis. You can get the most out of the city. First, select the mini control channel element for PCFICH, select the mini control channel element for PHICH from the remaining mini control channel elements, and finally configure the control channel element (CCE) using the remaining mini control channel elements and use it for the PDCCH. A series of processes ensure that the mini control channel elements occupied by the individual control channels do not collide with each other.
