The present disclosure relates to a method of controlling a timeout event for a data packet transmission in a wireless communications network, and a node performing the method. In an aspect, a method of controlling a timeout event for a data packet transmission in a wireless communications network is provided, wherein a data packet retransmission timer initially is set to a timeout value indicating the maximum allowed round-trip time (RTT) for the data packet transmission and a timeout event occurs upon the retransmission timer expiring. The method includes observing the RTT for the data packet transmission over a connection in the network, increasing, upon the retransmission timer expiring before a measured value is available for the observed RTT, the timeout value for the retransmission timer, and determining whether a currently set timeout value for the retransmission timer is to be decreased or not.

A slave station system 2 includes: a first shared slave station device 10 connected to a plurality of master station devices including at least a first master station device 3a and a second master station device 3b different from the first master station device 3a, and a second shared slave station device 20 connected to the first shared slave station device 10. The first shared slave station device 10 is equipped with a first individual function unit 11a corresponding to the first master station device 3a and a second individual function unit 11b corresponding to the second master station device 3b. The second shared slave station device 20 is equipped with a common function unit 21 connected to the first individual function unit 11a and the second individual function unit 11b and functioning regardless of the types of the plurality of master station devices.

A method includes: receiving, by a network data analytics function entity, a first message that is sent by an application function entity and that includes a measurement event and an identity ID of an application; obtaining a first measurement parameter based on the measurement event; receiving, by the network data analytics function entity, a notification message that is sent by a terminal and that is used to indicate the network data analytics function entity to perform data collection on the application; sending a second message including the ID of the application and the first measurement parameter to a policy control function entity, and requesting the policy control function entity to send the second measurement parameter to the terminal.

Methods, systems, and devices for wireless communications are described. A first parent node of a wireless backhaul network may receive, from a donor node of the wireless backhaul network, a token for a child node of the wireless backhaul network, the token being unique to a first wireless link between the first parent node and the child node. The first parent node may determine that a triggering event has occurred for a second wireless link between the first parent node and a second parent node. The first parent node may transmit, in response to determining that the triggering event has occurred, the token to the child node over the first wireless link to indicate for the child node to select a third parent node of the wireless backhaul network.

Disclosed herein is a wireless mesh network comprised of ultra-high-capacity nodes that are capable of establishing ultra-high-capacity links (e.g., point-to-point or point-to-multipoint bi-directional communication links) using a millimeter wave spectrum, including but not limited to 28 Ghz, 39 Ghz, 37/42 Ghz, 60 Ghz (including V band), or E-band frequencies, as examples. The higher capacity and/or extended range of these ultra-high-capacity nodes/links may be achieved via various advanced signal processing techniques. Further, these ultra-high-capacity nodes/links may be used in conjunction with other types of point-to-point and/or point-to-multipoint links to build a multi-layer wireless mesh network.
