Abstract: A method for managing data packets transmitted by a first user equipment to be received by a second user equipment through a radio network includes having the radio network comprising a radio transceiver station receive data packets transmitted by the first user equipment. For each data packet received, checking whether the data packet comprises a request for a data packet tunneling. For each data packet comprising a request for data packet tunneling, providing the data packet to a relay protocol entity at a Radio Link Control protocol layer. The relay protocol entity is configured for generating at least one tunneling data packet, said generating at least one tunneling data packet comprises inserting at least a portion of the transmitted data packet into the at least one tunneling data packet and transmitting the tunneling data packet to the second user equipment.

Abstract: A method manages sub-frame data transmission in a cellular network including a macro node and at least one small node associated therewith. The method includes at a macro node side: based on channel quality information from user equipment associated with the macro node, grouping the user equipment into a first group that can be served at a macro node first transmission power and a second group that has to be served at a macro node second transmission power higher than the macro node first transmission power, and determining a sub-frames pattern including: a number of no-transmission sub-frames wherein data transmission is prevented at the macro node side, a number of limited-transmission sub-frames wherein data transmission is allowed at the macro node side at only the first transmission power, and a number of normal-transmission sub frames wherein data transmission is allowed at the macro node side at the second transmission power.

Abstract: It is disclosed a method for supporting a machine-to-machine communication over a mobile communication network. The communication involves machine-to-machine devices that connect to the mobile communication network through a gateway including a transceiver module to connect to the mobile communication network over a radio link. The method includes determining whether a radio carrier is present over the radio link, and in the absence of the radio carrier, switching off the transceiver module for a first time period. After the first time period elapsed, the transceiver module is switched on for a second time period. The method further includes, after the second time period elapsed, repeating steps above. The first time period and the second time period are determined on the basis of a number of parameters whose value depend on at least one set of values provided to the gateway by the mobile communication network.

Abstract: A first user equipment can communicate with a second user equipment in a direct mode or in an infrastructure mode via a base station of a network. To communicate with the second user equipment, the first user equipment generates packets and forwards the packets to a lower protocol layer of a protocol stack. The first user equipment also acts as a buffer protocol entity by storing the packets until acknowledgement of receipt is received from the second user equipment. If the first user equipment switches from the direct mode to the infrastructure mode, or vice versa, the first user equipment forwards each of the stored packets to the lower protocol layer for transmission to the second user equipment using the current mode.

Abstract: A method for allocating communication resources for communications performed by user equipment in a mobile communication network comprises receiving a first indication about an amount of available communication resources and obtaining information about interfering communications between user equipment. The method further comprises, for each communication between user equipment to which communication resources have to be allocated, receiving a second indication about an available communication rate for an infrastructure-based communication and for a device-to-device communication, receiving a third indication about a requested communication rate for said each communication, making a selection between an infrastructure-based communication type or a device-to-device communication type based on the first, second and third indications and the information about interfering communications, and allocating communication resources to each communication on the basis of the selection between an infrastructure-based communication type or a device-to-device communication type.

Abstract: A method for scheduling radio resource allocation among active flows within a wireless communication network. The method includes, at each working period of the scheduling method; for each active flow, checking presence of priority data to be transmitted within the current working period. Each active flow having priority data to be transmitted within the current working period is classified as a priority active flow. The remaining active flows are classified as non-priority active flows, the non-priority active flows having non-priority data that need not to be transmitted within the current working period. Radio resources are allocated among the priority active flows, and corresponding priority data are transmitted over the respective allocated resources. After completing priority data transmission, the radio resources are allocated among the non-priority active flows and corresponding non-priority data are transmitted over the respective allocated radio resources until the end of the current working period.
