US 8,077,690 B2 · Resource allocation in cellular communication systems

Abstract

A method for assigning resources to frequency selective (FS) and frequency non-selective (FNS) users, for example, in an orthogonal frequency-division multiplexing (OFDM) wireless communication system, including assigning a first frequency resource to at least one FS user during a time interval, wherein the first frequency resource includes at least two near contiguous sub-carriers, and assigning a second frequency resource to at least one FNS user during the same time interval, the second frequency resource includes for each FNS user at least two non-contiguous sub-carriers, wherein the first and second frequency resources are part of a common frequency channel.

A method for assigning frequency selective (FS) and frequency non-selective (FNS) resources to users in an orthogonal frequency-division multiplexing (OFDM) wireless communication system, the method comprising:

assigning, at a scheduling entity, a FS frequency resource to a first user during a time interval,
the FS frequency resource assignment includes at least two contiguous sub-channels;
assigning a FNS frequency resource to a second user during the same time interval,
the FNS frequency resource assignment includes at least two sub-channels non-contiguous in frequency,
wherein the FS resource and FNS resource assignments are part of a common frequency channel and wherein the at least two non-contiguous sub-channels of the FNS frequency resource assignment are separated by not less than one quarter of the common frequency channel.
