US 2022/0030458 A1 · DETERMINING DATA AVAILABLE FOR TRANSMISSION

Abstract

Apparatuses, methods, and systems are disclosed for determining data available for transmission. One method includes associating a packet data convergence protocol entity with a first radio link control entity and a second radio link control entity belonging to two different cell groups. The method includes determining an amount of data available for transmission, the amount of data available for transmission including packet data convergence protocol data and radio link control data pending for initial transmission in the first radio link control entity and the second radio link control entity. The method includes comparing the amount of data available for transmission with a threshold. The method includes submitting the packet data convergence protocol data to a first radio link control entity in response to the amount of data available for transmission being below the threshold.

Dependent claims

A method of a user equipment, the method comprising:

establishing an uplink split bearer, wherein establishing the uplink split bearer comprises associating a packet data convergence protocol entity with a first radio link control entity and a second radio link control entity;
receiving first configuration information for the first radio link control entity, wherein the first configuration information indicates that the first radio link control entity is a primary radio link control entity;
configuring the first radio link control entity based on the first configuration information;
and
in response to one link being used for an uplink data transmission of the uplink split bearer, transmitting the uplink data transmission using the first radio link control entity.
