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 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 of broadcasting a message among user equipment in a broadcast area covered by a wireless communication network is proposed. The wireless communication network comprises at least one radio base station which is adapted to manage communications of user equipment in one or more respective served areas. The method comprises having the at least one radio base station identifying user equipment comprised in the broadcast area; among the user equipment within the broadcast area, estimating a set of transmitter user storing the message to be broadcasted; among the user equipment within the broadcast area, estimating a set of receiver user equipment not storing the message and being able to receive the message sent by at least one transmitter user equipment through a device to device communication, and selecting a subset of transmitter user equipment for transmitting the message ensuring that the receiver user equipment in said set receive the message with a predetermined confidence.

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.
