Disjoint bearer routing

Abstract

Methods and apparatus for switching bearers between radio access technologies (RATs) are described. According to aspects of the present disclosure, the uplink part of a bearer may be served by one RAT, while the downlink part of the bearer is served by another RAT. A part of a bearer may be served by more than one RAT. Methods and apparatus for communicating via bearer with parts served by differing RATs are also described.

1 . A method for wireless communications by a first base station (BS), comprising:
 establishing a data connection with a user equipment (UE) via one or more data bearers;   making, for a first data bearer of the one or more data bearers, a first determination to route uplink traffic from the UE during a period via the first BS or a second BS different from the first BS;   making, for the first data bearer of the one or more data bearers, a second determination to route downlink traffic to the UE during the period via the first BS or the second B S;   receiving, during the period, uplink traffic for the first data bearer according to the first determination, and   transmitting, during the period, downlink traffic for the first data bearer according to the second determination.
