Wireless communication system using multiple-serving nodes

A wireless device in a Long Term Evolution (LTE) wireless communication system, the wireless device comprising:

• a processor coupled to a memory containing processor-executable instructions, wherein the processor is configured to:
• receive a first physical downlink control channel (PDCCH) and a first physical hybrid automatic repeat request indicator channel (PHICH) from a first serving node simultaneously with receiving a second PDCCH and a second PHICH from a second serving node geographically positioned separately from the first serving node, wherein the first and second serving nodes are each configured to schedule transmissions with the wireless device without coordinating with one another such that uplink and downlink transmissions between the first serving node and the wireless device are scheduled independently from uplink and downlink transmissions between the second serving node and the wireless device;
• and
• transmit a first physical uplink control channel (PUCCH) to the first serving node simultaneously with transmitting a second PUCCH to the second serving node,
• wherein the wireless device receives data from the first serving node in a physical downlink shared channel (PDSCH) and transmits the data to the second serving node in a physical uplink shared channel (PUSCH),
• wherein the first PDCCH, the first PHICH, and the PDSCH are multiplexed to be transmitted from the first serving node, and
• wherein the second PUCCH and the PUSCH are multiplexed to be transmitted to the second serving node.

A system of communication in a Long Term Evolution (LTE) wireless communication system, the system of communication comprising:

• a wireless device;
• a first serving node communicatively linked to the wireless device;
• and
• a second serving node communicatively linked to the wireless device and geographically positioned separately from the first serving node, wherein the first and second serving nodes are configured to schedule transmissions with the wireless device without coordinating with one another such that uplink and downlink transmissions between the first serving node and the wireless device are scheduled independently from uplink and downlink transmissions between the second serving node and the wireless device;
• wherein the first serving node transmits a first physical downlink control channel (PDCCH) and a first physical hybrid automatic repeat request indicator channel (PHICH) to the wireless device simultaneously with the second serving node transmitting a second PDCCH and a second PHICH to the wireless device;
• wherein the wireless device transmits a first physical uplink control channel (PUCCH) to the first serving node simultaneously with transmitting a second PUCCH to the second serving node;
• wherein the wireless device receives data from the first serving node in a physical downlink shared channel (PDSCH) and transmits the data to the second serving node in a physical uplink shared channel (PUSCH);
• wherein the first PDCCH, the first PHICH, and the PDSCH are multiplexed to be transmitted from the first serving node;
• and
• wherein the second PUCCH and the PUSCH are multiplexed to be transmitted to the second serving node.
