A survey on 3GPP heterogeneous networks
Aleksander Damnjanovic,J. Montojo,Yongbin Wei,Ji Tingfang,Tao Luo,Madhavan Srinivasan Vajapeyam,Taesang Yoo,Osok Song,Durga Prasad Malladi +8 more
TL;DR: The need for an alternative strategy, where low power nodes are overlaid within a macro network, creating what is referred to as a heterogeneous network is discussed, and a high-level overview of the 3GPP LTE air interface, network nodes, and spectrum allocation options is provided, along with the enabling mechanisms.
Patent
Registration and access control in femto cell deployments
TL;DR: In this paper, the authors describe a system and methodologies that facilitate distributing and/or utilizing a Closed Subscriber Group (CSG) Identifier (ID) that identifies a CSG corresponding to a base station and distinguishes between the base station permitting access to members of the CSG and not-members.
Patent

Rajarshi Gupta,Fatih Ulupinar,Parag A. Agashe,Peerapol Tinnakornsrisuphap,Rajat Prakash,Gavin Bernard Horn,Gerardo Giaretta,Kalle Ahmavaara,Osok Song +8 more
TL;DR: In this article, the authors propose to provide different mobility management functionality at different nodes in a system whereby mobility management for a given node may be provided by a different node for different types of traffic.
Patent
Method and apparatus for transmitting and receiving status report comprising received status of packet data in a mobile communication system
TL;DR: In this article, a method and terminal apparatus for transmitting a status report comprising a received status of packet data in a mobile communication system are provided, in which whether transmission of an implicit Negative Acknowledge (NACK) signal is required for requesting retransmission of at least one non-received data packet whose sequence number is unidentified is determined, if transmission of the implicit NACK signal was required, and if transmission was not required, the status report was transmitted to the transmitter.
Patent
Managing network-initiated quality of service setup in mobile device and network
TL;DR: In this paper, the authors describe a system that manages the employment of network-initiated resource allocation and user equipment (UE) in the context of policy and charging control (PCC).
