Frequency hopping

摘要

A communications node operable to communicate with another communications node over a communications channel having a plurality of frequency resources, the communications node includes data defining a division of the communications channel into a plurality of contiguous sub-bands each having N frequency resources, wherein each frequency resource in a sub-band has a corresponding frequency resource in each of the other sub-bands, data defining an initial allocation of the frequency resources, a resource determination module operable to apply a frequency shift to the initially allocated frequency resources in accordance with a frequency hopping sequence to determine frequency resources to use for communicating information with the other communications node, wherein the frequency shift applied moves the initially allocated frequency resources to corresponding frequency resources in another sub-band, a transceiver for communicating information with the other communications node using the determined frequency resource.

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 in which there is stored data defining a division of the communications channel into a plurality of contiguous sub-bands each having N frequency resources, wherein each frequency resource in a sub-band has a corresponding frequency resource in each of the other sub-bands; a memory in which there is stored 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, wherein the frequency shift applied moves the set of contiguously allocated resource blocks to corresponding frequency resources in another sub-band; a transceiver for communicating information with the other communications node using the determined frequency resource.
