Journal ArticleDOI
DS-CDMA synchronization in time-varying fading channels
TL;DR: An estimator based on subspace identification techniques is proposed, and the Cramer-Rao bound, which serves as an optimality criterion, is derived and is experimentally shown to be robust against the near-far problem.
Proceedings ArticleDOI
WCDMA enhanced uplink - principles and basic operation
TL;DR: An overview of the design targets, the basic principles, and how they are integrated into WCDMA are given.
Proceedings ArticleDOI

Pucch resource allocation for carrier aggregation in lte-advanced
Astely David,Baldemair Robert,Dirk Gerstenberger,Daniel Larsson,Lars Lindbom,Stefan Parkvall +5 more
TL;DR: In this article, the authors propose a method and apparatus for signaling uplink control information in a mobile communication network using carrier aggregation, which allows the transmission, on a single uplink component carrier, of control information associated with a downlink transmission on multiple aggregated downlink component carriers.
Patent
Using an uplink grant as trigger of first or second type of CQI report
TL;DR: In this article, a UE and an associated base station receive channel state feedback from the UE to determine whether the UE has received an uplink grant from the base station or not.
