First Claim
Patent Images
1. A method of operating a node of a telecommunications system, the method comprising:
- controlling how many Control Channel Elements, CCEs, of a frequency or time division multiplexing radio interface are used to transmit a Physical Downlink Control Channel, PDCCH, message to a User Equipment unit, UE, based on a rate of expected responses that the node does not receive from the UE for previously transmitted PDCCH messages to the UE.

Abstract
Methods and nodes of a telecommunications system are disclosed. How many Control Channel Elements of a Frequency Division Multiplexing radio interface are used to transmit a Physical Downlink Control Channel message from a node of the telecommunications system to a User Equipment unit are controlled based on whether the node received from the User Equipment unit a response to a prior Physical Downlink Control Channel message transmitted to the User Equipment unit.

11. A node of a telecommunications system, the node comprising:
-
a transceiver configured to communicate over a frequency or time division multiplexing radio interface with a User Equipment unit, UE; and a Physical Downlink Control Channel, PDCCH, processor configured to control how many Control Channel Elements, CCEs, of the radio interface are used to transmit a PDCCH message to the UE based on a rate of expected responses that the node does not receive from the UE for previously transmitted PDCCH messages to the UE. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
