A wafer support pin has a front end contacted with a wafer such that the front end is flat or rounded. Thus, gravitational stress is minimized during annealing the wafer, thereby minimizing slip dislocation. This wafer support pin is suitably used for annealing of a wafer, particularly high temperature rapid thermal annealing of a large-diameter wafer.

An apparatus and method for feeding back Channel Quality Information (CQI) in a wireless communication system are provided. Total channels are grouped into certain number of groups according to downlink channel estimates. Group indexes are determined for the channels. Feedback information is generated using the group indexes of the channels and representative values of the groups. Then, the generated feedback information can be transmitted.

A low-complexity dynamic channel allocation apparatus and method in a multi-carrier communication system are provided. In the low-complexity dynamic channel allocation method, subcarriers are initially allocated to total users and two users are selected from among all possible cases of two users out of the total users. The power gain of each of the subcarriers initially allocated to the selected two users is calculated, which can be generated by reallocating each subcarrier to the other user through subcarrier swapping. The power gains of the initially allocated subcarriers are ordered for each of the selected users and a pair of subcarriers with the greatest power gains for the two users are selected. Subcarriers are reallocated to the two users by swapping the selected subcarriers between the two users.
