Dynamic reception procedures for device energy saving
A radio access network node may configure a user equipment with primary and secondary discontinuous reception occasion resource information. The node may transmit traffic to the user equipment that is received by the node at a regular/predictable rate during primary discontinuous reception ON periods. If the node receives traffic of a flow at an irregular or unpredictable rate, the node may transmit a secondary reception occasion indication to the user equipment indicative of secondary reception occasion resources usable by the user equipment during a configured primary discontinuous reception OFF period to receive the irregular or unpredictable traffic. The secondary reception occasion indication may comprise an index indicative of secondary discontinuous reception occasion resource information configured in the user equipment, which may maintain a receiver chain in an active state to receive the irregular or unpredictable traffic during an indicated secondary reception occasion ON period.
