UNBALANCED WIRELESS COMMUNICATION WITH GROUP OF DEVICES
Aspects of this disclosure relate to group of wireless communication devices communicating with a network system in a coordinated manner. The wireless communication can be unbalanced between uplink and downlink. In some instances, the network system can wirelessly communicate uplink data with the group of devices and wirelessly communicate downlink data with a single device of the group. In some other instances, the network system can wirelessly communicate downlink data with the group of devices and wirelessly communicate uplink data with a single device of the group.
1 . A method of multiple-input multiple-output (MIMO) wireless communication, the method comprising:
receiving, by a network system, first uplink MIMO data associated with a primary user equipment from the primary user equipment;
receiving, by the network system, second uplink MIMO data associated with the primary user equipment from a secondary user equipment, wherein the primary user equipment is in communication with the secondary user equipment via a peer-to-peer link;
aggregating, by the network system, the first uplink MIMO data together with the second uplink MIMO data; and
transmitting, by the network system, downlink data associated with the primary user equipment to a single user equipment via cellular communications.
2 . The method of claim 1 , wherein the single user equipment is the primary user equipment.
3 . The method of claim 1 , further comprising sending a pairing command, by the network system, to at least one of the primary user equipment or the secondary user equipment, wherein the pairing command initiates coordinated transmission of the uplink MIMO data by the primary user equipment and the secondary user equipment to the network system.
4 . The method of claim 1 , further comprising sending, by the network system, a command to cause the peer-to-peer link to be established.
5 . The method of claim 1 , further comprising obtaining, by the network system, joint channel information associated with the primary user equipment and the secondary user equipment, wherein the aggregating is based on the joint channel information.
6 . The method of claim 1 , further comprising determining, by the network system, that the first uplink data and the second uplink data are both associated with the primary user equipment based on a common identifier.
7 . The method of claim 1 , further comprising establishing a tunnel between the network system and the primary user equipment through the secondary user equipment, wherein the second uplink data MIMO data is received from the secondary user equipment via the tunnel.
8 . The method of claim 1 , wherein the first uplink MIMO data and the second uplink MIMO data are received via the same serving node of the network system.
9 . The method of claim 1 , wherein the first uplink MIMO data and the second uplink MIMO data are received via different transmit-receive points.
10 . The method of claim 1 , wherein the network system comprises a plurality of distributed transmit-receive points.
11 . The method of claim 1 , wherein the receiving the first uplink MIMO data and the receiving the first uplink MIMO data are performed at least partly concurrently.
12 . A method of multiple-input multiple-output (MIMO) wireless communication, the method comprising:
while a primary user equipment is in communication with a secondary user equipment via a peer-to-peer link,
transmitting, by a network system, a first part of a downlink MIMO data transmission for the primary user equipment to the primary user equipment;
transmitting, by the network system, a second part of the downlink MIMO data transmission for the primary user equipment to the secondary user equipment; and
receiving, by the network system, uplink data for the primary user equipment from a single user equipment via cellular communications.
13 . The method of claim 12 , wherein the single user equipment is the primary user equipment.
14 . The method of claim 12 , wherein the single user equipment is the secondary user equipment.
15 . The method of claim 12 , further comprising obtaining, by the network system, joint channel information associated with the primary user equipment and the secondary user equipment, wherein the transmitting the first part of the downlink MIMO data and the transmitting the second part of the downlink MIMO data are based on the joint channel information.
16 . The method of claim 12 , further comprising:
determining, by the network system, to pair the primary user equipment and the secondary user equipment for coordinated transmission of downlink data; and
in response to the determining, transmitting, by the network system, a pairing command to at least one of the primary user equipment or the secondary user equipment.
17 . The method of claim 12 , further comprising sending, by the network system, a command to initiate the peer-to-peer link.
18 . The method of claim 12 , wherein the transmitting the first part of the downlink MIMO data and the transmitting the second part of the downlink MIMO data comprise providing different spatial beams to the primary user equipment and the secondary user equipment such that the different beams are spatially multiplexed.
