Patent number: 11968554Abstract: Systems and methods are provided for dynamically changing a channel state information (CSI) reporting protocol by adjusting CSI reporting frequency for a wireless device communicating with an access node within a wireless network. The methods and systems identify undesirable signal performance parameters at a particular wireless device and adjust the CSI reporting frequency when the undesirable signal performance parameters meet a predetermined threshold. The method changes the CSI reporting frequency for the wireless device to enable more frequent CSI reporting to the access node to facilitate reallocation of resources.Type: GrantFiled: June 30, 2020Date of Patent: April 23, 2024Assignee: Sprint Spectrum LPInventor: Sreekar Marupaduga

Patent number: 11930459Abstract: Methods and systems are provided for dynamically disabling beamforming functionality of one or more frequency bands. For example, a frequency band may have beamforming enabled. One or more user devices may be connected to the frequency band having beamforming enabled for access to a wireless telecommunications network. User devices connected with the frequency band may be at various locations of a network cell of the wireless telecommunications network (e.g., a cell center, middle cell, cell edge). Fading information may be received by one or more of the user devices connected with the frequency band. One or more fading channel measurements of the first frequency band may be above a threshold.

Patent number: 11910253Abstract: When a first radio of a UE has an air-interface connection with an access node on a first carrier and the UE encounters a trigger for the UE to scan for and report to the access node coverage on a second carrier, a second radio of the UE, rather than the first radio of the UE, will conduct the scanning, and the first radio of the UE will then report to access node over the air-interface connection on the first carrier a result of the scanning conducted by the second radio. Optimally, the first radio of the UE thus need not tune away from its air-interface connection with the access node in order for the UE to scan for target coverage on the second carrier. And the process could thereby help avoid the interruption of communication between the UE and the access node on the air-interface connection over the first carrier.Type: GrantFiled: April 15, 2022Date of Patent: February 20, 2024Assignee: T-Mobile USA, Inc.Inventors: Anurag Thantharate, Sougata Saha, Sreekar Marupaduga

Patent number: 11901645Abstract: Systems, methods, and computer-readable media herein dynamically adjust the number of elements active within a neighboring base station in order to reduce the back lobe overlap and thus reduce the interference caused by such an overlap. User devices assigned to communicate with an antenna array are monitored to determine if they are experiencing a decreased level of performance which may be caused by an overlapping back lobe from a neighboring cell site. If the user device's performance falls below a threshold value, the gain associated with the neighboring cell site is dynamically reduced in order to reduce the back lobe overlap.Type: GrantFiled: December 9, 2022Date of Patent: February 13, 2024Assignee: T-MOBILE INNOVATIONS LLCInventor: Sreekar Marupaduga
