Patent
Method and apparatus for communication system
TL;DR: In this paper, the reception node identifies some missing units among the transmitted data units and transmits a reduced status message to the transmission node through a radio link, which includes a negative response to the first part of missing data units.
Patent
Improved protocol synchronization for harq background
TL;DR: In this paper, the authors propose a method and an apparatus to detect lost protocol synchronization in HARQ systems caused by ACK/NACK errors, and to prevent protocol synchronization errors by sending scheduling grants on a packet-by-packet basis.
Patent
Reducing state transition time
TL;DR: In this paper, a method and an arrangement for reducing a state transition time from a power saving state for a user equipment (18) in a communication network is presented, where the user equipment(18) one or more information parameter, such as the radio network temporary identifier for a high speed downlink shared channel (H-RNTI), is retained in order to enable a time reduction when said user equipment switches back from said power-saving state.

Procede et systeme pour assurer des retransmissions autonomes dans un systeme de communication sans fil
TL;DR: In this article, an emetteur pouvant presenter une disponibilite de puissance marginale peut retransmettre de maniere autonome des trames transmises precedemment contenant les memes donnees.
Patent
Methods and arrangements for mobile communications network
TL;DR: In this paper, an improved procedure for synchronization of reconfiguration of RRC procedures between a radio base station and UE is proposed, which is achieved by associating a new configuration to be used by UE with an additional UE identity.
