Abstract: A method and Radio Access Network (RAN) Intelligent Controller (RIC) modeling interference patterns in a Massive Multiple Input, Multiple Output (MIMO) network. Information associated with beams transmitted in an Open RAN (O-RAN) is obtained. An interference matrix identifying interference patterns is generated based on the information associated with the beams transmitted in the O-RAN. One or more optimization solutions are determined based on the interference patterns identified in the interference matrix. One or more signals are sent to one or more elements in the O-RAN to implement the one or more optimization solutions.

Abstract: In a communication system (100) where a wireless relay node (RN) (114) relays data packets between a Node B (112) and a user equipment (UE) (102), the RN receives (608) a data packet from the Node B via a first wireless link (115), conveys (614) the received data packet to the UE via a second wireless link (120), determines (616) whether the UE is likely to handoff, and in response to determining that the UE is likely to handoff, delays conveying (620, 622) an acknowledgment of the data packet to the Node B until an acknowledgment has been received from the UE. In another embodiment, the RN may use a status report (720) to inform the Node B of data packets that have not been transmitted to the UE or that have been transmitted to the UE but for which an acknowledgement has not been received from the UE.

Abstract: A method, system, and base station for providing subband signal to noise ratio (SNR) correction in the scheduling of communication resources. A Scheduling Correction (SC) utility receives periodic subband and wideband channel quality indicator (CQI) reports from one or more wireless devices. The SC utility records a subframe report period for a respective subband CQI report. The SC utility calculates the age of the subband report to determine whether the subband CQI report remains valid. If the subband report is invalid, the SC utility utilizes the wideband CQI report for (current) transmission scheduling. However, if the subband report is valid, the SC utility utilizes: (a) the subband CQI report for transmission scheduling from the most current reporting subframe; or (b) a modified subband CQI value with a correction that utilizes the wideband CQI report, if the subband CQI report was not received at the most current reporting subframe.
