Inter-cell interference coordination for E-PDCCH
First Claim
Patent Images
1. A method for communication in a wireless telecommunication system, the method comprising:
- processing an indicator;
transmitting, by a first access node, the indicator to a second access node over an interface between the first access node and the second access node, wherein the indicator provides information on a transmission of a control channel by the first access node; and
transmitting, by the first access node, the control channel in an enhanced physical downlink control channel (E-PDCCH) region, wherein the control channel is frequency-division-multiplexed with data transmission, wherein the E-PDCCH region is a legacy Physical Downlink Shared Channel (PDSCH) region in which a physical downlink control channel (PDCCH) is transmitted, wherein the indicator includes one power threshold defined for the E-PDCCH.

16. A first access node in a wireless telecommunication system, the first access node comprising:
-
a memory; and a processor coupled to the memory comprising processor-executable instructions, wherein the processor is configured such that the first access node transmits over an interface between the first access node and a second access node an indicator that provides information on a transmission of a control channel and transmits the control channel in an enhanced physical downlink control channel (E-PDCCH) region, wherein the control channel is frequency-division-multiplexed with data transmission, wherein the E-PDCCH region is a legacy Physical Downlink Shared Channel (PDSCH) region in which a physical downlink control channel (PDCCH) is transmitted, wherein the indicator includes one power threshold defined for the E-PDCCH. - View Dependent Claims (17, 18, 19, 20, 21)

22. A user equipment comprising:
-
a processor; and a receiver coupled to the processor and configured to receive a control channel that was transmitted in a resource block that is frequency-division-multiplexed with a data channel, wherein the resource block is located in a region whose configuration is transmitted from an access node serving the user equipment to another access node, wherein the control channel is transmitted in an enhanced physical downlink control channel (E-PDCCH) region, wherein the control channel is frequency-division-multiplexed with data transmission, wherein the E-PDCCH region is a legacy Physical Downlink Shared Channel (PDSCH) region in which a physical downlink control channel (PDCCH) is transmitted, wherein the indicator includes one power threshold that is defined for the E-PDCCH. - View Dependent Claims (23, 24, 25)
