  • Patent number: 10785679
    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.

  • Publication number: 20200128606
    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.

  • Patent number: 9036624
    Abstract: Data streams are transmitted from a node towards a receiver in a communication network in the form of data packets for playout via a reproduction buffer at the receiver. The data packets are arranged in a scheduling queue and dropped from the scheduling queue if their sojourn time in the queue exceeds a given drop deadline. The reproduction buffer is emulated at the node in order to determine respective playout values for the data packets which are indicative of expected playout instants for the data packets by the reproduction buffer at the receiver. The drop deadlines are assigned to the data packets as a function of the respective playout values determined via the reproduction buffer as emulated at the node.

  • Patent number: 8964867
    Abstract: A method executed in a wireless communication network including at least one base station associated to a corresponding area transmitting/receiving data to/from corresponding user terminals located within the area. The method generates a user-rate matrix for each base station. Each element of the user-rate matrix provides a corresponding score, in terms of achievable rate, to a user terminal or group of user terminals within the corresponding area when a transmission is made to/from the user terminal or group of user terminals, respectively, from/to the base station by employing a selected transmission mode. The method further processes the elements of the user-rate matrix to create a scheduling list sorting the elements by a decreasing score, and associating to each user terminal a corresponding selected transmission mode based on the scheduling list for the transmission/reception of data to/from the base station.

  • Patent number: 8908511
    Abstract: In a method of scheduling transmission services over a high speed packet access communication link such as a HSDPA and/or a HSUPA link a list of queues is created for transmission services to be provided over the link. The queues, which include both Real Time and Non Real Time queues, are allotted respective service priorities based e.g. on a channel quality indicator and/or a Quality of Service indicator to produce an ordered list of queues based on the service priorities. The link resources needed for serving at least one set of queues having higher priorities in the ordered list are estimated and a check is made. If these resources are available, the set of queues having higher priorities in the ordered list are served. If the resources required are not available, at least one queue is removed from the ordered list of queues.

  • Patent number: 8767760
    Abstract: In a communication network, a node receives from user equipment information on the length of a queue of information units to be transmitted to the node from the user equipment. The information, for possible use by the node in scheduling transmission of these information units from the user equipment, is in the form of quantized queue length information indicative of a lower bound and an upper bound for the queue length. Transmission of information units from the user equipment to the node is detected at the node, and an improved estimate of the queue length is produced by correcting the lower bound and the upper bound via subtraction of the number of the detected information units transmitted from the user equipment to the node.
