The network node monitors a congestion level for communication, and, if the congestion level reaches a first threshold, the network node orders for at least one device in a RRC connected mode to be released from the RRC connected mode to an RRC idle mode or an RRC inactive mode, thereby disabling a capability of the at least one device to provide one or more re-transmission requests while keeping an ability of the at least one device to further receive the multicast transmission.

Abstract: The disclosure relates to an OTDOA positioning technique wherein different base stations transmit different variations of the same basic PRS or other positioning signal synchronously as an SFN signal to effect an observed time shift at the UE between the different variations of the basic PRS signal or positioning signal. This added time shift resulting from the transmission of different variations by different base stations effectively spreads the corresponding channel impulses in the CIR of the SFN signal in the time domain so that the UE is better able to detect and discriminate between different instances of the positioning signal transmitted from different base stations.
