RESOURCE ALLOCATION BY COMPONENT CARRIER SUB-BANDS

摘要

A user equipment UE is signaled to utilize a second format for downlink control information as opposed to a first format. Resources allocated by the first format are not bandwidth-restricted respecting a carrier and resources allocated by the second format are restricted to a subset of bandwidth sub-bands. The UE is then scheduled on resources that are restricted to the subset of sub-bands using the second format. In various specific embodiments the sub-bands are defined by predetermined static frequency bounds for the UE specifically or for the entire cell; the sub-bands may be defined by a predetermined algorithm which identifies a sub-band index as a function of UE identity, system frame number, and/or a number of sub-bands which are in the subset. The second format has a resource allocation field whose length depends on how many physical resource blocks are in the sub-bands and therefore in the subset.
