Abstract

A method, system, and computer program product for transmission of data in a wireless communications system. A first downlink data is transmitted to a user equipment using a first downlink frequency. A first uplink data is received from the user equipment utilizing a first uplink frequency. A second downlink data is transmitted to the user equipment using a second downlink frequency. A second uplink data is received using the first uplink frequency.

First claim

What is claimed is:

1. A computer-implemented method, comprising:
receiving, by a first base station, an uplink control information from a second base station;
transmitting, by the first base station, a downlink control information to the second base station;
scheduling, by at least one of the first and second base stations, based on the received uplink control information and downlink control information, at least one data packet for transmission on a downlink to at least one user device; and
transmitting, by at least one of the first and second base stations, the at least one data packet to the at least one user device;
wherein at least one of the first and second base stations are communicatively coupled to at least one centralized unit; and
the method further comprises receiving from the at least one centralized unit, by the at least one of the first and second base stations communicatively coupled to the at least one centralized unit, Packet Data Convergence Protocol (PDCP) control information configured to be used by the at least one of the first and second base stations communicatively coupled to the at least one centralized unit in transmitting the at least one data packet.

2. The method according to claim 1 , wherein the uplink control information includes at least one of the following: at least one downlink acknowledgment/non-acknowledgement associated, a channel state information, a precoding matrix indicator, a rank indicator, and any combination thereof.

3. The method according to claim 1 , wherein the downlink control information includes a modulation coding scheme.

4. The method according to claim 3 , wherein the downlink control information includes a resource indication value.

5. The method according to claim 1 , wherein the first base station and the second base station are configured to exchange at least one of the following: a buffer status information associated with at least one of the first base station and the second base station, an average throughput associated with at least one of the first base station and the second base station, a cell loading associated with at least one of the first base station and the second base station, a channel quality associated with at least one of the first base station and the second base station, and any combination thereof.

6. The method according to claim 1 , where the first and second base stations include at least one of the following: an eNodeB base station, a gNodeB base station, and any combination thereof.

7. The method according to claim 6 , wherein at least one of the first base station and the second base station includes at least one of the following: a radio transmitter, a radio receiver, and any combination thereof.

8. The method according to claim 7 , wherein the first and second base stations are base stations operating in at least one of the following communications systems: a long term evolution communications system and a new radio communications system.

9. The method according to claim 6 , wherein the at least one centralized unit is configured to terminate communications with at least one of the first and second base stations.

10. The method according to claim 1 , wherein the at least one centralized unit includes a multi-connectivity traffic shaping function component configured to determine a size of one or more packet data units for transmission to at least one of the first and second base stations, wherein the size of the one or more packet data units is determined based on a radio link control buffer status associated with at least one of: the first base station, the second base station, the at least one centralized unit, and any combination thereof, wherein the one or more packet data units are transmitted to at least one of the first and second base stations.

11. A system comprising:
at least one programmable processor; and
a non-transitory machine-readable medium storing instructions that, when executed by the at least one programmable processor, cause the at least one programmable processor to perform operations comprising:
receiving, by a first base station, an uplink control information from a second base station;
transmitting, by the first base station, a downlink control information to the second base station;
scheduling, by at least one of the first and second base stations, based on the received uplink control information and downlink control information, at least one data packet for transmission on a downlink to at least one user device; and
transmitting, by at least one of the first and second base stations, the at least one data packet to the at least one user device;

wherein at least one of the first and second base stations are communicatively coupled to at least one centralized unit; and
the operations further comprise receiving from the at least one centralized unit, by the at least one of the first and second base stations communicatively coupled to the at least one centralized unit, Packet Data Convergence Protocol (PDCP) control information configured to be used by the at least one of the first and second base stations communicatively coupled to the at least one centralized unit in transmitting the at least one data packet.

12. The system according to claim 11 , wherein the uplink control information includes at least one of the following: at least one downlink acknowledgment/non-acknowledgement associated, a channel state information, a precoding matrix indicator, a rank indicator, and any combination thereof.

13. The system according to claim 11 , wherein the downlink control information includes a modulation coding scheme.

14. The system according to claim 13 , wherein the downlink control information includes a resource indication value.

15. The system according to claim 11 , wherein the first base station and the second base station are configured to exchange at least one of the following: a buffer status information associated with at least one of the first base station and the second base station, an average throughput associated with at least one of the first base station and the second base station, a cell loading associated with at least one of the first base station and the second base station, a channel quality associated with at least one of the first base station and the second base station, and any combination thereof.

16. The system according to claim 11 , where the first and second base stations include at least one of the following: an eNodeB base station, a gNodeB base station, and any combination thereof.

17. The system according to claim 16 , wherein at least one of the first base station and the second base station includes at least one of the following: a radio transmitter, a radio receiver, and any combination thereof.

18. The system according to claim 17 , wherein the first and second base stations are base stations operating in at least one of the following communications systems: a long term evolution communications system and a new radio communications system.

19. The system according to claim 11 , wherein the at least one centralized unit is configured to terminate communications with at least one of the first and second base stations;
wherein the at least one centralized unit includes a multi-connectivity traffic shaping function component configured to determine a size of one or more packet data units for transmission to at least one of the first and second base stations, wherein the size of the one or more packet data units is determined based on a radio link control buffer status associated with a
