Abstract: A method for positioning in a wireless communication system is described. The method comprises receiving, by a second node (102), a capability-request signal from a first node (106). The second node (102) transmits a capability-response signal to the first node (106). The second node (102) transmits an assistance information to the first node (106). The second node (102) transmits the configuration of the at least one reference signal to a third node (104). The second node (102) receives a reference signal from the third node (104). The second node (102) performs measurement on the reference signal and transmits report comprising the measurement to the first node (106), where the first node (106) estimates a position of the third node (104) based on the report received from the second node (102).

Abstract: In one embodiment an approach is provided to efficiently program routes on line cards and fabric modules in a modular router to avoid hot spots and thus avoid undesirable packet loss. Each fabric module includes two separate processors or application specific integrated circuits (ASICs). In another embodiment, each fabric module processor is replaced by a pair of fabric module processors arranged in series with each other, and each processor is responsible for routing only, e.g., IPv4 or IPv6 traffic. The pair of fabric module processors communicates with one another via a trunk line and any packet received at either one of the pair is passed to the other of the pair before being passed back to a line card.
