Abstract
Idle mobile devices are used as cooperating devices to support coordinated multipoint transmission and reception for uplink and downlink communications between a primary mobile device and its serving base station. For uplink communications, the cooperating mobile devices receive the uplink transmission from the primary mobile device and retransmit the received data signal to the serving base station for the primary mobile device. For downlink communications, the cooperating mobile devices receive the downlink transmission from the serving base station and retransmit the received data signal to the primary mobile device.
Claims44
A method implemented by a cooperating mobile device in a wireless communication network for supporting coordinated multipoint transmission and reception for a primary mobile device, said method comprising:
- joining, by said cooperating mobile device, a coordinating set for the primary mobile device, said coordinating set including a serving base station for the primary mobile device;
- receiving, by the cooperating mobile device as a member of said coordinating set, a data signal transmitted from one of the primary mobile device and the serving base station to the other;
- and
- retransmitting, by the cooperating mobile device as a member of said coordinating set, the data signal to the other of the serving base station and the primary mobile device.
A cooperating mobile device in a wireless communication network for supporting coordinated multipoint transmission and reception for a primary mobile device, said cooperating mobile device comprising:
- a transceiver circuit configured to transmit and receive signals over a wireless communication channel;
- and
- a processing circuit including a coordinated multipoint control circuit and configured to:
- join a coordinating set for the primary mobile device, said coordinating set including a serving base station for the primary mobile device;
- receive, as a member of the coordinating set for the primary mobile device, a data signal transmitted from one of the primary mobile device and the serving base station to the other;
- and
- retransmit, as a member of the coordinating set for the primary mobile device, the data signal to the other of the serving base station and the primary mobile device.
A method implemented by a serving base station in a wireless communication network for supporting coordinated multipoint transmission and reception for a primary mobile device, said method comprising:
- receiving, by the serving base station, a first data signal transmitted by a primary mobile device;
- receiving, by the serving base station, a second data signal as retransmitted by a cooperating mobile device in a coordinating set for the primary mobile device, wherein the second data signal comprises a retransmission of the first data signal;
- and
- combining the first and second data signals to produce a combined data signal.
A base station in a wireless communication network for supporting coordinated multipoint transmission and reception for a primary mobile device, said base station comprising:
- a transceiver circuit configured to transmit and receive signals over a wireless communication channel;
- and
- a processing circuit including a coordinated multipoint control circuit and configured to:
- receive a first copy of a data signal transmitted by a primary mobile device;
- receive a second data signal as retransmitted by a cooperating mobile device in a coordinating set for the primary mobile device;
- and
- combine the first and second data signals to produce a combined data signal.
A method of coordinated multipoint reception implemented by a primary mobile device, said method comprising:
- receiving, by the primary mobile device, a first data signal transmitted by a serving base station;
- receiving, by the primary mobile device, a second data signal transmitted by a cooperating mobile device in a coordinating set for the primary mobile device, wherein the second data signal comprises a retransmission of the first data signal;
- and
- combining the first and second data signals to produce a combined data signal.
A primary mobile device in a wireless communication network capable of coordinated multipoint reception, said mobile device comprising:
- a transceiver circuit configured to transmit and receive signals over a wireless communication channel;
- and
- a processing circuit including a coordinated multipoint control circuit and configured to:
- receive a first data signal transmitted by a serving base station;
- receive a second data signal transmitted by a cooperating mobile device in a coordinating set for the primary mobile device, wherein the second data signal comprises a retransmission of the first data signal;
- and
- combine the first and second data signals to produce a combined data signal.
