The method of claim 1 , wherein, after transmitting the configuration information, the third cell transmits a message to the first cell and the second cell requesting that the first cell and the second cell provide, on a one-time basis or on a periodic basis, status information regarding usage of one or more resource blocks shared by the first cell and the second cell.
10. The method of claim 9 , wherein the third cell uses the status information to determine at least one different resource block that is to be shared by the first cell and the second cell, and wherein the third cell provides a location of the at least one different resource block to the first cell and the second cell.
11. The method of claim 1 , wherein the configuration information is provided to the second cell by the first cell and is determined by the first cell based on information received from the second cell, the received information comprising at least one of:
at least one maximum number of transmission layers possible in the second cell; and
at least one allowed number of transmission layers requested by the second cell.
12. The method of claim 11 , wherein the received information is received by the first cell in a response to a coordinator request message transmitted from the first cell to the second cell, the coordinator request message further including a request by the first cell to act as a coordinator for resource sharing between the first cell and the second cell, and the response further indicating acceptance or non-acceptance by the second cell of the request by the first cell to act as a coordinator.
13. The method of claim 1 , wherein the configuration information is determined through a negotiation procedure performed by the first cell and the second cell, the negotiation procedure comprising the first cell and the second cell sending to one another a configuration message containing information pertinent to the respective cell, the information comprising at least one of a maximum number of transmission layers possible in the respective cell, a number of transmission layers requested by the respective cell, a reference signal configuration requested by the respective cell for signal demodulation and measurement, and a modulation format requested by the respective cell for use within shared resource blocks, wherein configuration messages continue to be exchanged between the first cell and the second cell until the first cell and the second cell agree on configuration information that is acceptable to both the first cell and the second cell.
14. A system for communication in a wireless telecommunication network, the system comprising:
a first cell capable of transmitting, to a first user equipment (UE), a first signal on a resource block configured to be shared by more than one cell; and
