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 allocating resource blocks of a transmission frame on a cellular network. The cellular network includes a cluster of antennas and a master unit of the cluster. Each antenna of each cluster is configured to provide radio coverage over a corresponding cell to exchange data with corresponding user equipment in communication with the antenna. During the transmission frame the antennas of the cluster are configured to be selectively activated and muted according to a plurality of cluster muting conditions.

Abstract: A method for managing a cellular network, which comprises a plurality of macro nodes defining respective macro cells and a plurality of small nodes within said macro cells, the method comprising, at each current time snapshot of a plurality of time snapshots and for each macro cell, providing, according to a history traffic load of the cellular network, an overload probability in a first configuration of the cellular network with only macro nodes activated. The method further comprises identifying, among said plurality of time snapshots, first candidate time snapshots for small nodes deactivation in each first candidate time snapshot the overload probability being lower than a threshold overload probability, and if the current time snapshot is one among the first candidate time snapshots, deactivating each small node having a current number of allocated radio resources lower than a threshold number.
