20080318612 | Method and Apparatus For Limiting Peer-to-Peer Communication Interference - Peer-to-peer communication between user terminals in a licensed spectrum is enabled by a method comprising the following steps: —communicating directly, peer-to-peer, between the first and the second mobile terminal, and —disconnecting the peer-to-peer communication in dependence of control signals received or not received from the base station. Thus, according to the invention, the network is enabled to control the peer-to-peer communication between two user terminals. | 12-25-2008 |
20100034185 | Radio quality based channel resource management - The present invention provides a quality based resource management fin a radio communications system. In this resource management, channel resources are dynamically allocated to a multi-resource capable mobile unit based on a radio quality of a radio link between the mobile unit and an associated base station. Thus, the amount of these resources to be allocated to the mobile unit is determined based on this radio quality and can be dynamically updated based on new quality reports. A high experienced quality means that more resources are allocated. The quality based resource allocation can also be combined with a quality based transmission scheduling. In such a case, mobile units experiencing a high quality are allowed to transmit more often in a period of time than mobile units with low quality. | 02-11-2010 |
