System and method for boundaryless service in wireless networks with cooperative transmission points

A network component for serving one or more user equipment (UEs) experiencing inter-transmission point group (TPG) interference in a wireless network, the network component comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• select a set of TPs from a plurality of TPGs in a network to serve an edge UE (EU) experiencing inter-TPG interference at a plurality of resource units (RUs), the plurality of TPGs comprising a first TPG and a second TPG, wherein the EU experiences inter-TPG interference from the first TPG at a first RU and experiences inter-TPG interference from the second TPG at a second RU, and wherein the set of TPs is selected according to a metric associated with the EU including a channel condition of the EU;
• group the selected set of TPs into a first TPG patch (TPGP) for the first RU and a second TPGP for the second RU, the first TPGP comprising one or more TPs of the first TPG, and the second TPGP comprising one or more TPs of the second TPG;
• and
• perform transmission coordination for the EU between the one or more TPs of the first TPGP and other terminals of the network at the first RU and transmission coordination for the EU between the one or more TPs of the second TPGP and other terminals of the network at the second RU.

• and
• implement inter-TPG cooperation for transmission between the TPs from the first TPG for the first RU and between the TPs from the second TPG for the second RU while maintaining required quality of service (QoS) for other terminals.

A method performed by a network component for serving one or more user equipment (UEs) experiencing inter-transmission point group (TPG) interference in a wireless network, the method comprising:

• selecting a set of transmission points (TPs) from multiple TPGs in a network to serve an edge UE (EU) experiencing inter-TPG interference at a plurality of resource units (RUs), the set of TPs selected according to a metric associated with the EU including a channel condition of the EU;
• grouping the selected set of TPs into a TPG patch (TPGP) for at least one of the plurality of RUs;
• performing transmission coordination for the EU between the TPs of the TPGP and other terminals of the network;
• for each of the TPs from the TPGs, considering for the TPGP a next TP with a better channel condition to the EU;
• performing a joint transmission to the EU using all current considered TPs;
• removing a last considered TP from the TPGP upon determining that the TPGP with all current considered TPs results in lowering network-wide utility to at least on UE outside the TPGP below an acceptable threshold;
• and
• discarding the TPGP upon determining that an improvement in the channel condition of the EU under consideration using the TPGP is below a predetermined threshold.
