Abstract

The invention proposes method of providing measurement reports. The eNodeB sends (S 10 , S 11 ) a user equipment information about a plurality of subframe patterns used by a plurality of wireless networks respectively, and notifies (S 12 , S 13 ) the user equipment associations between the measurement reports and said plurality of subframe patterns. The user equipment measures (S 14 ) channel information in at least one subframe patterns, generates measurement reports for said at least one subframe patterns according to said association, and sends (S 15 , S 16 ) said measurement reports to said eNodeB. The eNodeB relates (S 17 ) each of the received measurement reports with the corresponding subframe pattern according to said association.

First claim

What is claimed is:

1. A method, in a user equipment, of providing measurement reports, wherein said user equipment is interfered by a plurality of wireless networks, said method comprising:
receiving, from a eNodeB, information about a plurality of subframe patterns respectively used by said plurality of wireless networks;
obtaining, from the eNodeB, associations between the measurement reports and said plurality of subframe patterns;
measuring channel information in at least one subframe patterns, and generating measurement reports for said at least one subframe patterns according to said association;
sending said measurement reports to said eNodeB.

2. A method according to claim 1 , wherein said subframe pattern comprises positions of at least one of blank frames and almost blank frames in said pattern, and said measuring step measures said channel information according to signals from the eNodeB and interferences from said plurality of wireless networks in said blank frames and/or almost blank frames in said pattern.

3. A method according to claim 1 , wherein said receiving step receives the information about said plurality of subframe patterns via RRC signaling, one measurement report is associated with one pattern, and wherein said association comprises one of the following:
the measurement report is associated with the pattern relating to the index of the subframe in which the user equipment sends the measurement report;
the measurement report is associated the pattern relating to the index of the subframe in which the user equipment received the request for measurement report from the eNodeB.

4. A method according to claim 3 , wherein said obtaining step further comprises at least one of:
receiving, from the eNodeB, instruction to send the measurement report for one specific pattern;
receiving, from the eNodeB, instruction to activate or deactivate the measurement report for one specific pattern.

5. A method according to claim 1 , wherein said receiving step receives said plurality of subframe patterns through either user equipment specific signaling or multicast/broadcast signaling; and/or wherein the method further comprises the step before said measuring step and said sending step: receiving, from the eNodeB, instruction to provide or not to provide said measurement reports.

6. A method according to claim 1 , wherein said user equipment is Pico user equipment, said eNodeB is a Pico eNodeB and said plurality of wireless networks are macro cells; or wherein said user equipment is macro user equipment, said eNodeB is a macro eNodeB and said plurality of wireless networks are femto cells.

7. A method, in an eNodeB, of assisting a user equipment to provide measurement reports, wherein said user equipment is interfered by a plurality of wireless networks, said method comprising:
sending said user equipment information about a plurality of subframe patterns used by said plurality of wireless networks respectively;
notifying said user equipment associations between the measurement reports and said plurality of subframe patterns;
receiving measurement reports from said user equipment, said measurement reports are based on channel information measured by said user equipment in at least one of said plurality of subframe patterns;
relating each of the received measurement reports with the corresponding subframe pattern according to said association.

8. A method according to claim 7 , wherein said subframe pattern comprises positions of at least one of blank frames and almost blank frames in said pattern, and said channel information is measured according to signals from the eNodeB and interferences from said plurality of wireless networks measured by said user equipment in said blank frames and/or almost blank frames.

9. A method according to claim 7 , wherein said sending step sends the information about a plurality of subframe patterns via RRC signaling, and one measurement report is associated with one pattern, said association comprises one of the following:
the measurement report is associated with the pattern relating to the number of subframe in which the eNodeB is to receive the measurement report from the user equipment;
the measurement report is associated the pattern relating to the number of subframe in which the eNodeB sends the request for the measurement report to the user equipment.

10. A method according to claim 7 , said notifying step comprising either:
notifying the user equipment to send the measurement report for one specific pattern; or
notifying the user equipment to activate or deactivate the measurement report for one specific pattern.

11. A method according to claim 7 , wherein said sending step sends said plurality of subframe patterns through user equipment specific signaling or multicast/broadcast signaling; and wherein the method further comprises the step of:
sending instruction to the user equipment to provide or not to provide measurement reports.

12. A method according to claim 8 , further comprising:
scheduling data transmissions to the user equipment on at least one of said blank frames and said almost blank frames, according to the measurement reports together with the corresponding subframe pattern.

13. A method according to claim 7 , wherein said eNodeB is a Pico eNodeB, said user equipment is Pico user equipment, and said plurality of wireless networks are macro cells; or wherein said eNodeB is a macro eNodeB, said user equipment is macro user equipment, and said plurality of wireless networks are femto cells.

14. A device, in a user equipment, of providing measurement reports, wherein said user equipment is interfered by a plurality of wireless networks, said device comprises:
a fifth unit for receiving, from a eNodeB, information about a plurality of subframe patterns respectively used by said plurality of wireless networks;
a sixth unit for obtaining, from the eNodeB, associations between the measurement reports and said plurality of subframe patterns;
a seventh unit for measuring channel information in at least one subframe patterns, and generating measurement reports for said at least one subframe patterns according to said association;
an eighth unit for sending said measurement reports to said eNodeB.

15. A device, in an eNodeB, of assisting a user equipment to provide measurement reports, wherein said user equipment is interfered by a plurality of wireless networks, said device comprises:
a first unit for sending said user equipment information about a plurality of subframe patterns used by said plurality of wireless networks respectively;
a second unit for notifying said user equipment associations between the measurement reports and said plurality of subframe patterns;
a third unit for receiving measurement reports from said user equipment, said measurement reports are based on channel information measured by said user equipment in at least one of said plurality of subframe patterns;
a fourth unit for relating each of the received measurement reports with the corresponding subframe pattern according to said association.

16. A method according to claim 1 , wherein said receiving step receives the information about said plurality of subframe patterns via RRC signaling, and one measurement report is associated with one pattern.

17. A method according to claim 1 , wherein said association comprises one of the following:
the measurement report is associated with the pattern relating to the index of the subframe in which the user equipment sends the measurement report;
the measurement report is associ
