Abstract
A method for multi-connectivity between a plurality of base stations and user equipment includes estimating, at the user equipment, a first round trip time (RTT) taken in transmitting first data to a first base station, estimating, at the user equipment, a second RTT taken in transmitting second data to a second base station, and determining a size of the first data which is to be transmitted to the first base station, based on the first RTT and the second RTT.
Claims20
A method performed by a user equipment communicating with a plurality of base stations through a plurality of channels, the method comprising:
- estimating a first round trip time (RTT) based on a first block error rate (BLER) of a first channel among the plurality of channels;
- estimating a second RTT based on a second BLER of a second channel among the plurality of channels;
- determining a size of first uplink data and a size of second uplink data based on the first RTT and the second RTT;
- and
- transmitting the first uplink data and the second uplink data through the first channel and the second channel, respectively,
- wherein the first uplink data and the second uplink data are included in uplink data to be transmitted through the plurality of channels.
A method performed by a first base station communicating with a user equipment through a first channel, the method comprising:
- estimating a first round trip time (RTT) based on a first block error rate (BLER) of the first channel;
- obtaining a second RTT of a second channel, wherein the user equipment communicates with a second base station through the second channel;
- determining a size of first downlink data and a size of second downlink data based on the first RTT and the second RTT;
- transmitting the first downlink data through the first channel;
- and
- providing the second downlink data to the second base station,
- wherein the first downlink data and the second downlink data are included in downlink data to be transmitted to the user equipment.
A method performed by a common internet protocol anchor communicating with a user equipment through plurality of base stations, the method comprising:
- obtaining a first round trip time (RTT) of a first channel between the user equipment and a first base station among the plurality of base stations;
- obtaining a second RTT of a second channel between the user equipment and a second base station among the plurality of base stations;
- calculating a size of first downlink data and a size of second downlink data based on the first RTT and the second RTT;
- providing the first downlink data and the second downlink data to the first base station and the second base station, respectively,
- wherein the first downlink data and the second downlink data are included in downlink data to be transmitted to the user equipment, and
- wherein the first RTT and the second RTT are estimated based on a first block error rate (BLER) of the first channel and a second BLER of the second channel, respectively.
