valued i, where i is an integer. If NLGPRU = 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 multicarrier support is provided, an allocation including the last ith mini-band LRU in partition FP0 is allocated together with the ith guard mini-band LRU. When the adjacent RF carrier is not an active carrier for the MS, the guard sub-carriers in between active and non-active 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. 9.8.2 Uplink Subchannelization and Permutation The subchannelization schemes in the uplink are similar to the downlink with the exception of the difference in permutation granularity. Similar to downlink, each uplink subframe is divided into a number of frequency partitions (i.e., FPi, i = 0, 1, 2, 3), where each partition comprises a set of physical resource units across the number of OFDM symbols available in the subframe. Each frequency partition can include localized and/or distributed physical resource units. Each frequency partition can be used for different purposes, such as fractional frequency reuse. A physical resource unit is the basic physical unit for resource allocation in the uplink which contains Psc sub-carriers by Nsym OFDM symbols. The Psc parameter is equal to 18 and the number of OFDM symbols Nsym is equal to 6, 7, 5, or 9, depending on the type of subframe (i.e., type-1, type-2, 9.8 Subchannelization and permutation type-3, or type-4). Similarly, a logical resource unit is defined as the basic unit for distributed and localized resource allocations which have the same size as a physical resource unit. The size of logical resource units for uplink control chan
