Patent number: 12034645Abstract: A voice coding rate is selected for a voice call involving a user equipment (UE) device based on an air interface efficiency of the base station serving the UE device. The air interface efficiency of the base station is determined based on at least one of (i) a beamforming capability of the base station, (ii) a multi-user multiple-input multiple-output (MU-MIMO) capability of the base station, or (iii) an antenna configuration of the base station. The voice coding rate could be selected by either the UE device or by the base station. The UE device transmits to the base station during the voice call one or more voice frames that convey voice data coded at the selected voice coding rate. During the voice call, a new air interface efficiency may be determined, and a new voice coding rate may be selected based on the new air interface efficiency.Type: GrantFiled: May 13, 2022Date of Patent: July 9, 2024Inventors: Hemanth B.

Patent number: 11849437Abstract: Disclosed are methods and systems to facilitate management of carriers to help ensure QoS for single-carrier UEs. In particular, a base station may serve one or more first user equipment devices (UEs) on just a first carrier. While doing so, the base station may determine that each of the one or more first UEs being served on just the first carrier is receiving threshold low quality of service from the base station on the first carrier. Responsive to this determining, the base station may (i) select one or more second UEs based on the one or more second UEs being served by the base station on both the first carrier and one or more other carriers and (ii) discontinue serving each selected second UE on the first carrier while continuing to serve each selected second UE on one or more other carriers.Type: GrantFiled: March 18, 2021Date of Patent: December 19, 2023Assignee: Sprint Spectrum LLCInventors: Chunmei Liu, Pratik Kothari, Hemanth B.

Method and system for latency-based management of carriers on which to serve a user equipment device
Patent number: 11357004Abstract: A method and system for managing carriers on which a base station provides service to a user equipment device (UE), based on consideration of latency. A base station that is arranged to operate on a plurality of carriers may, while serving a UE on a set of one or more carriers of the plurality, select, from at least two other carriers of the plurality, an additional carrier to add to the set of one or more carriers on which the base station serves the UE, and may make the selection based a latency on the selected carrier. In response to selecting the additional carrier, the base station may add the selected carrier to the set of one or more carriers on which the base station serves the UE, and may then serve the UE on the set of one or more carriers including the selected carrier.Type: GrantFiled: November 24, 2015Date of Patent: June 7, 2022Assignee: Sprint Spectrum L.P.Inventors: Hemanth B.

Patent number: 11343832Abstract: Systems and methods are described for transmitting a beamformed signal to a wireless device proximate to an antenna system. An uplink signal may be received at an access node from a wireless device in communication with the access node. It may be detected that the wireless device is proximate to an antenna system, wherein the antenna system does not comprise the access node. The detection may be based on a determined location for the wireless device, an indication from the antenna system, a retrieved signal level metric for the wireless device, and the like. It may be then determined that a beamformed signal is to be transmitted to the wireless device based on the detecting. And the beamformed signal may be transmitted from the access node to the wireless device.Type: GrantFiled: February 11, 2016Date of Patent: May 24, 2022Assignee: T-Mobile Innovations LLCInventors: Hemanth Pawar, Krishna Sitaram, Pratik Kothari, Chunmei Liu

Patent number: 10548063Abstract: A wireless device or UE is configured to function as a relay on behalf of a donor access node. The relay UE performs call admission controls including balancing the resources of the relay access node with the resources provided by the donor access node providing services to end UEs via the relay access node, i.e. a backhaul connection of the relay UE. The backhaul throughput is compared to a throughput requirement of the end UEs being served by the relay UE. If the throughput requirement is larger than the backhaul throughput, any new connection requests from an additional end UE may be rejected. A threshold may be defined to ensure that there are ample resources at the backhaul prior to accepting connection requests from additional end UEs.Type: GrantFiled: November 24, 2015Date of Patent: January 28, 2020Assignee: Sprint Spectrum L.P.Inventors: Chunmei Liu, Krishna Sitaram, Hemanth Pawar, Pratik Kothari

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: 10440716Abstract: A method and system for controlling wireless communication over an air interface between a base station and a user equipment device (UE) served by the base station. In examples, the base station is configured to use a particular modulation and coding scheme (MCS) to transmit downlink control signals over the air interface to the UE without the base station beamforming the downlink control signals to the UE. Responsive to the base station determining that the UE is experiencing threshold poor RF conditions on the air interface, the base station reconfigures itself to beamform downlink control signals to the UE. And, given that the base station is reconfigured to beamform downlink control signals to the UE, the base station further reconfigures itself to use a higher-order MCS to transmit downlink control signals to the UE.Type: GrantFiled: January 6, 2017Date of Patent: October 8, 2019Assignee: Sprint Spectrum L.P.Inventors: Hemanth B.

Patent number: 10383101Abstract: Link adaptation for an uplink channel is dynamically performed based on changes in uplink resources in the wireless network, the changes based on frame configuration. If the ratio of uplink to downlink subframes in the new frame configuration is smaller, the throughput is increased by increasing a modulation and coding scheme of the uplink channel, and transmit power of wireless devices. If the ratio of uplink to downlink subframes is increased in the new frame configuration, the throughput is decreased, and the wireless device is instructed to transmit using reduced transmit power.Type: GrantFiled: March 6, 2017Date of Patent: August 13, 2019Assignee: Sprint Spectrum L.P.Inventors: Hemanth Pawar, Krishna Sitaram, Chunmei Liu, Pratik Kothari

Patent number: 10320519Abstract: Methods and systems for controlling service by a base station when the base station is serving both a first UE without carrier aggregation and a plurality of second UEs with carrier aggregation. As a basis for invoking carrier aggregation service for the first UE, the base station selects one of the second UEs to transition from being served by the base station with carrier aggregation to being served by the base station without carrier aggregation. The base station makes such a selection based at least in part on a modulation and coding scheme that the base station uses to serve the selected one of the second UEs. The base station transitions from serving the selected second UE with carrier aggregation to serving the selected second UE without carrier aggregation. And the base station transitions from serving the first UE without carrier aggregation to serving the first UE with carrier aggregation.Type: GrantFiled: January 23, 2017Date of Patent: June 11, 2019Assignee: Sprint Spectrum L.P.Inventors: Pratik Kothari, Chunmei Liu, Hemanth B.
