This application provides a data sending method and a communication apparatus. The method includes: A first node determines, based on a quality of a channel between the first node and a second node, a sending time for starting to send data, where the first node is one of several candidate previous-hop nodes of the second node. The first node starts to send the data to the second node at the sending time. According to the data sending method, when a node needs to send data to a next-hop node of the node, the node may determine, based on quality of a channel between the node and the next-hop node of the node, a sending time for starting to send the data.

A method is provided for each router to individually manage retransmissions at run time in a single chip computer die or a single computer that includes cores or compute nodes and routers that interconnect the cores or the compute nodes. Each router compares static energy saving and dynamic energy increase from turning off a retransmission buffer of the router in a monitoring phase. When the static energy saving is greater than the dynamic energy increase, the router turns off the retransmission buffer in a subsequent monitoring phase. When the static energy saving is less than the dynamic energy increase, the router turns on the retransmission buffer in the subsequent monitoring phase.

A calculation accuracy of a communication quality for use in selecting a communication path is improved. A radio communication device includes: a first calculator configured to calculate a transmission quality indicator value of each of a plurality of parent candidate nodes on the basis of a transmission frame transmitted from an own device to each of the plurality of parent candidate nodes; a second calculator configured to calculate a reception quality indicator value of each of the parent candidate nodes on the basis of a reception frame transmitted from each of the plurality of parent candidate nodes and received by the own device; and a selector configured to select a parent node for use in the communication path among the plurality of parent candidate nodes on the basis of the transmission quality indicator value and the reception quality indicator value.

Techniques are directed to determining a rank value associated with a first network node. An example method includes determining a second network node indicated as being a preferred parent network node for the first network node. A first rank value is processed to determine a second rank value, the first rank value corresponding to a path from the second network node to a destination network node, including rounding up the first rank value in a predetermined manner to at least a second next higher integral rank value than the first rank value, to determine the second rank value. The second rank value is processed with at least a third rank value to determine the rank value associated with the first network node, the third rank value associated with a path from one of a plurality of candidate parent network nodes, for the first network node, to the destination network node.

The present disclosure relates to a pre-5th-generation (5G) or 5G communication system for supporting higher data rates beyond 4th-generation (4G) communication systems such as a long term evolution (LTE) system. The disclosure includes a first evolved node B (eNB) in a communication system supporting dual connectivity. The first eNB includes a controller configured to detect that a path between a second eNB and a terminal is blocked, and a transmitter configured to transmit, to the terminal, a first data unit of a plurality of data units to be transmitted through the path between the second eNB and the terminal.

A wireless communication system includes a first wireless communication device, and a second wireless communication device. The first wireless communication device includes: a communicator that delivers, to the second wireless communication device, data addressed to a third wireless communication device and receives, from the second wireless communication device, information on communication quality according to failed data of which delivery fails among the data delivered from the second wireless communication device to the third wireless communication device; and a controller that controls delivery of the data in accordance with the information on the communication quality.

A method of managing a telecommunications network, the telecommunications network having a first user and a second user, the method comprising the step of: ascertaining a competitive characteristic associated with the first user and a competitive characteristic associated with the second user (210); comparing the ascertained competitive characteristics (220); identifying whether there is a disparity between the competitive characteristics that exceeds a threshold (230), thereby to identify a competitive advantage associated with the first or second user; and if it is identified that the disparity exceeds the threshold, adapting a network configuration of a network connection associated with the first user so as to offset the competitive advantage associated with the first or second user (240).

Certain aspects of the present disclosure provide techniques for support response-based resource management. A UE may determine an uplink response to be transmitted in response to a downlink transmission by a first TRP participating in CoMP to the UE with a second TRP. The first UE may select which of the first TRP or the second TRP to transmit the uplink response to, based at least in part on the determined uplink response and may transmit the uplink response to the selected first or second TRP.
