Patent number: 10771128Abstract: A wireless communication network uses Multi-User Multiple Input Multiple Output (MU-MIMO). Network circuitry stores geographic data that indicates geographic containers. Transceiver circuitry wirelessly receives network signaling from User Equipment (UEs) located in the geographic containers. The network circuitry processes the network signaling to determine UE MU-MIMO correlation factors between the UEs and associate the UE MU-MIMO correlation factors with the geographic containers. The network circuitry processes the UE MU-MIMO correlation factors associated with the geographic containers to determine container MU-MIMO correlation factors between the geographic containers. The network circuitry selects UEs for MU-MIMO based on their container MU-MIMO correlation factors.

Patent number: 10681598Abstract: A wireless communication network serve User Equipment (UEs) over Fifth Generation New Radio (5GNR) and Long Term Evolution (LTE). A 5GNR access node receive user data for wireless delivery to the UEs and splits the user data into LTE and 5GNR portions. The 5GNR access node transfers the 5GNR portion to the UEs over 5GNR links and transfers the LTE portion to an LTE access node over X2 links. The LTE access node transfers the LTE portion to the UEs over LTE links. The 5GNR access node identifies X2 link quality. When the X2 link experiences low quality, the 5GNR access node transfers user data to the UEs over 5GNR links without splitting the data to LTE. When the X2 link status has adequate quality, then the 5GNR access node starts splitting user data to LTE again.Type: GrantFiled: August 21, 2019Date of Patent: June 9, 2020Assignee: Sprint Communications Company L.P.Inventors: Krishna D.

Patent number: 10439787Abstract: A Long Term Evolution (LTE) access node to serve User Equipment (UEs) with a wireless Carrier Aggregation (CA) data communication service. A data processing system schedules CA Primary Component Carriers (PCCs), CA intra-band Secondary Component Carriers (SCCs) and CA inter-band SCCs for the UEs. A wireless transceiver wirelessly exchanges user data with the UEs based on the scheduling to serve the UEs with the CA PCCs, the CA intra-band SCCs, and the CA inter-band SCCs. The data processing system detects that a number of the UEs exceeds a UE threshold, and in response, identifies the UEs that use an LTE channel for their CA inter-band SCCs but not for their CA PCCs. The data processing system disables the LTE channel for the UEs that use the LTE channel for their CA inter-band SCCs but not for their CA PCCs.Type: GrantFiled: November 27, 2017Date of Patent: October 8, 2019Assignee: Sprint Communications Company L.P.Inventors: Chunmei Liu, Hemanth Balaji Pawar, Pratik Kothari, Krishna D.

Patent number: 9736746Abstract: Systems and methods of operating multimode 3G/4G communications devices in an overlapping 3G/4G coverage area (e.g., WiMAX or LTE/CDMA-EvDO) include determining a loading condition of the 3G and 4G base stations. If the 3G and 4G base stations are lightly loaded, one or more 4G Channel Quality Indicators (CQI) are compared with one or more corresponding 3G Data Rate Control (DRC) indices to determine which of the 3G and 4G networks allows a higher data throughput. The dual mode communications device is handed off to a 4G base station associated with the 4G coverage if the 4G network allows the higher data throughput; otherwise, the dual mode communications device is handed off to a 3G base station. User priorities, application categories, and/or MIMO and diversity modes may be used to determine handoff if the base stations are more than lightly loaded.Type: GrantFiled: June 27, 2014Date of Patent: August 15, 2017Assignee: CLEARWIRE IP HOLDINGS LLCInventors: Swati Tiwari, Hemanth Balaji Pawar, Esmail Dinan, Krishna Sitaram, Jong-Hak Jung

Patent number: 9467938Abstract: Methods and systems are provided for using DRCLocks for conducting call admission control. In an embodiment, an access node provides service to a plurality of access terminals on a carrier in a coverage area, where the plurality of access terminals does not include a first access terminal. The access node receives a request for new service on the carrier in the coverage area from the first access terminal over an air interface, and responsively determines whether an aggregate-DRCLock condition is met. If the aggregate-DRCLock condition is met, the access node denies the request for new service.Type: GrantFiled: April 29, 2009Date of Patent: October 11, 2016Assignee: Sprint Spectrum L.P.Inventors: Shilpa Kowdley Srinivas, Anoop K.

Patent number: 9420474Abstract: A method includes communicating data to a plurality of user equipment (UE) in a cell using a plurality of beamforms. Each of the plurality of beamforms has a main lobe and side lobes, where the main lobe is directed toward a corresponding UE of the plurality of UE. For each beamform of the plurality of beamforms, a position of the beamform is determined. Furthermore, it is determined that one or more small cells of the plurality of small cells are available to serve the corresponding UE based on determining that the one or more small cells are positioned within the main lobe of the beamform using the determined position of the beamform and one or more positions of the one or more small cells. Based on the one or more small cells being determined as available to serve the corresponding UE, beamforming is disabled to the corresponding UE from the cell, thereby preventing the side lobes of the beamform from interfering with other radio communications in the cell.Type: GrantFiled: February 10, 2015Date of Patent: August 16, 2016Assignee: Sprint Communications Company L.P.Inventors: Hemanth Balaji Pawar, Krishna Datt Sitaram, Daniel Alberto Vivanco, Shilpa Kowdley Srinivas

Patent number: 9258754Abstract: Systems and methods of operating multimode 3G/4G communications devices in an overlapping 3G/4G coverage area (e.g., WiMAX or LTE/CDMA EvDO) include determining if a number associated with temporarily-disabled sectors of an available sector set of the multimode device while the device is operational with a 3G base station is at least equal to a threshold number. If the number is at least equal to the threshold number, a scan for a sector in the 4G network to handover the operation of the multimode device from the 3G base station associated with the 3G coverage to a 4G base station associated with the 4G coverage is initiated. A scan for a fixed period of time for a new available sector in the 3G network to be added in the available sector set may be initiated; and, if a new available sector is added to the sector set, it may be redetermined if the number associated with the temporarily-disabled sectors is at least equal to the threshold number, before initiating the scan for a sector in the 4G network.Type: GrantFiled: March 11, 2013Date of Patent: February 9, 2016Assignee: Clearwire IP Holdings LLCInventors: Hemanth Balaji Pawar, Krishna D.
