Abstract:
1. A communications node operable to communicate with another communications node over a communications channel having a plurality of frequency resources, the communications node comprising: a memory which stores data defining a division of the communications channel into a plurality of contiguous sub-bands each having N frequency resources; a memory which stores data defining an allocation of said frequency resources comprising a set of contiguously allocated resource blocks; a resource determination module operable to apply a frequency shift to the set of contiguously allocated resource blocks in accordance with a frequency hopping sequence to determine frequency resources to use for communicating information with the other communications node and in accordance with the following equation: where NRB is the total number of frequency resource blocks in the transmission band N is the number of contiguous frequency resource blocks in each sub-band x is the set of contiguously allocated resource blocks y is the frequency hopped resource t is a time counter a(t) is the frequency hopping shift applied at time point t, and is an integer value from the set {0, 1, . . . , S−1}; and S is the number of sub-bands; and a transceiver for communicating information with the other communications node using the determined frequency resource.
