Patent number: 11792742Abstract: Some techniques and apparatuses described herein permit a user equipment (UE) to transition among different power configurations, which include different values for different power parameters, that impact an amount of power consumed by the UE. In some aspects, these transitions may be signaled by a base station based at least in part on traffic volume for the UE, which may assist with improving throughput and/or extending battery life of the UE. Furthermore, these transitions may be signaled dynamically, such as in downlink control information (DCI) and/or a medium access control (MAC) control element (CE) MAC-CE, which may conserve battery power and/or network resources as compared to reconfiguring the UE using an RRC message, and which may allow the UE to be reconfigured quickly as conditions associated with the UE change.Type: GrantFiled: June 29, 2021Date of Patent: October 17, 2023Assignee: QUALCOMM IncorporatedInventors: Huilin Xu, Peter Pui Lok Ang, Wanshi Chen, Joseph Binamira Soriaga, Linhai He

Patent number: 11784695Abstract: Channel state information (CSI) operations are disclosed with regard to elevation beamforming (EB)/full dimension (FD) multiple input, multiple output (ED/FD-MIMO) operations. With CSI processing associated with multiple CSI-reference signal (CSI-RS) resources, ambiguities may arise in determining the CSI reporting type and rank. CSI reporting type may be determined using a last reported beam selection indicator (BI) or, in the absence of a BI, may be determined according to a predefined rule. When rank and BI are reported separately and rank is absent, user equipment may determine a default reference rank for CSI reporting based on either or both of previously reported rank or BI. When rank and BI are jointly reported, encoding schemes with fixed bitwidths determined based on either CSI-RS processes or resources may be used to enhance decoding. CSI-RS antenna ports, processes, or resources may also be used in determining application of CSI processing relaxation.Type: GrantFiled: January 25, 2022Date of Patent: October 10, 2023Assignee: QUALCOMM IncorporatedInventors: Chao Wei, Yu Zhang, Wanshi Chen, Peter Gaal
