SIGNALING FOR CONFIGURABLE DUAL-CLUSTER RESOURCE ASSIGNMENTS

摘要

A virtual resource block VRB tree is configured according to granularity of resource blocks RBs, cluster size options and frequency span, at least one of which is signaled on a downlink. A first cluster of RBs is identified by a first resource allocation RA index and selected from the configured VRB tree. A second cluster of RBs, separated in frequency from the selected first cluster of RBs and identified by a second RA index, is selected from the configured VRB tree. The selected first and second clusters of RBs selected from the configured VRB tree is mapped to respective first and second clusters of uplink physical RBs. Certain frequency band combinations of two RB clusters may be made illegal for various reasons. The granularity of RB may be Me {1, 2, 3, 4} physical RBs, and the cluster size options may be an integer k multiple of M.
