Abstract

The invention discloses an apparatus configured to report aperiodic channel state information for dual connectivity. Embodiments of a system and method for reporting channel state information (CSI) ina wireless network are generally described herein. In some embodiments, an apparatus of a User Equipment (UE) can include physical layer circuitry to receive, in a first subframe, a first aperiodic CSI request from a first cell group, and a second aperiodic CSI request from a second cell group. The UE can include processing circuitry to determine a number of requested CSI processes correspondingto the first aperiodic CSI request and the second aperiodic CSI request. Additionally, the processing circuitry can select a subset of the requested CSI processes when the determined number of requested CSI processes is more than five. Furthermore, the processing circuitry can calculate CSI for the selected CSI processes.

Description

[0001] Case Description [0002] This application is a divisional application of an invention patent application with an application date of October 16, 2015, an application number of 201580056191.6, and a title of "A device configured to report aperiodic channel state information for dual connectivity". technical field [0003] Embodiments relate to radio access networks. Some embodiments relate to aperiodic channel state information (CSI) processing and reporting in cellular networks, such as Long Term Evolution (LTE) and LTE-Advanced (LTE-A) networks. Background technique [0004] Current problems in transmitting data over wireless networks can include low throughput, frequent handovers, handover failures, inefficient offloading, and service interruptions. [0005] Dual connectivity in LTE networks can significantly improve throughput per user, reduce handovers, and reduce Switching failure. [0006] Regarding low throughput, dual connectivity can increase throughput ...
