Inconsistence with later statement. Rejected. See resolution for comment 591 593 23.3.5 Due to regulations and/or realtime channel usage siutations, the conditions of available TV channels could be quite different from each other. Need to optionally specify independent MCS value for each available TV channel, if multiple TV channels are to be used. Need to specify an option to permit use of independent MCS value for each available TV channel, if multiple TV channels are to be used. Rejected. See multiple MCS discussion. 594 23.3.5 Can the common MCS applied to the multiple TVWS channels where SINR values are highly fluctuated? Common MCS applied to the multiple TVWS channels could degrade the performance of TVWS network, where channel conditions are widely varied. Rejected. See multiple MCS discussion. 595 23.3.5 For aggregated channels, It is better to allow unequal MCS. Unequal MCS is more efficient when conditions varies from channel to channel. Insert 'Unequal MCSs could be applied to streams assigned to non-contiguous channels'. Rejected.
