<P>PROBLEM TO BE SOLVED: To assign resources corresponding to discontinuous portions of bandwidth. <P>SOLUTION: A single assignment may be used to assign multiple disjoint portions of bandwidth to be used by a wireless terminal at the same time as an uplink or downlink band. Different portions of bandwidth allocated to a terminal may have different numbers and/or locations of guard subcarriers with relevant guard subcarrier information being communicated to the wireless terminal in a broadcast signal or being determined from stored information. The disjoint portions of bandwidth allocated for use to a terminal may be separated by a carrier band, e.g., 1.25 MHz or more, which is not available for use because it is owned by another service provider. Some embodiments are implemented using OFDM signals where a wireless terminal may generate or receive a symbol including subcarriers (tones) corresponding to the different discontinuous portions but not the bandwidth separating the discontinuous portions. <P>COPYRIGHT: (C)2013,JPO&INPIT |
