 is an integer. If NLG-PRU = 0, then G-PRU[i] = G-PRUR[i]. If NRG-PRU = 0, then G-PRU[i] = G-PRUL[i]. The NG-PRU guard- PRUs are used as mini-band LRUs, i.e., the mini-band LRUs at frequency partition FP0 with no permutation for data transmission. The ith guard mini-band LRU is always allocated along with the last ith mini-band LRU in partition FP0. In other words, when an MS with multi-carrier capability is provided an allocation, it includes the last ith mini-band LRU in partition FP0 together with the ith guard mini-band LRU. When an adjacent component carrier is not an active carrier for the MS, the guard sub-carriers between active and inactive carriers are not utilized for data transmission. When the overlapped guard sub-carriers are not aligned in the frequency domain, they are not used for data transmission. The primary and secondary preambles, as well as the superframe headers, are present in fully- configured and partially-configured carriers. The location and transmission format of these overhead channels are the same as that of the single-carrier. The A-MAP is transmitted over a fully-configured component carrier. The location and transmission format of the A-MAP on the fully-configured carrier is the same as that for the single-carrier mode. Additional broadcast information related to multi- carrier operation is carried over the fully-configured carrier, except uplink information, additional broadcast information related to the operation of a partially-configured carrier can be carried on the partially-configured carrier. The uplink control channels corresponding to the single-carrier operation are supported for the fully-configured carrier. A partially-configured carrier may not include any uplink transmission capability, and is exclusively optimized for downlink-only transmission (e.g., multicast and broadcast services). The BS configures a set of component carriers on which the MS conducts measurements and sends feedback information. The BS may only allocate resources to the MS over a subset of co
