Claim of US Patent No. 10,172,122

1. A method of operating a Long-Term Evolution (LTE) base station to facilitate identification of uplink interference, wherein the LTE base station serves a plurality of User Equipment (UE) devices and one or more relay nodes, the method comprising:identifying a first scheduling group comprising the plurality of UE devices and a second scheduling group comprising the one or more relay nodes based on LTE registration data;
allocating uplink LTE resource blocks by scheduling a first portion of the uplink LTE resource blocks at one end of a channel spectrum to the UE devices in the first scheduling group and scheduling a second portion of the uplink LTE resource blocks at an opposite end of the channel spectrum to the one or more relay nodes in the second scheduling group; and
monitoring for interference in the uplink LTE resource blocks to determine if the interference is associated with the one or more relay nodes in the second scheduling group.
