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 corresponding 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 corresponding second determination, independent of the first determination, to route downlink traffic to the UE during the period via the first BS or the second BS, wherein the period ends when the first BS makes a next first determination or a next second determination for the first data bearer of the one or more data bearers; and
participating in the data connection based on the first and second determinations, wherein the participating comprises;
receiving, during the period, all uplink traffic for the first data bearer according to the corresponding first determination, andtransmitting, during the period, all downlink traffic for the first data bearer according to the corresponding second determination.

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.

10. A method for wireless communications, comprising:
-
receiving, from a first base station (BS), a first configuration indicating uplink traffic during a period for a first data bearer of one or more data bearers is to be sent via the first BS or a second BS different from the first BS, and downlink traffic during the period for the first data bearer of the one or more data bearers is to be sent via the first BS or the second BS, wherein the uplink and downlink traffic for the first data bearer of the one or more data bearers is independently configured for routing via the first BS or the second BS and wherein the period ends upon receiving a second configuration, different from the first configuration, from the first BS indicating uplink traffic during another period for the first data bearer of the one or more data bearers is to be sent via the first BS or the second BS, and downlink traffic during the other period for the first data bearer of the one or more data bearers is to be sent via the first BS or the second BS; and sending, via the first BS or the second BS, a configuration complete message to the first BS in response to the first configuration. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. An apparatus for wireless communications, comprising:
-
a processor configured to; establish a data connection with a user equipment (UE) via one or more data bearers; make, for a first data bearer of the one or more data bearers, a corresponding first determination to route uplink traffic from the UE during a period via a first base station (BS) or a second BS different from the first BS; make, for the first data bearer of the one or more data bearers, a corresponding second determination, independent of the first determination, to route downlink traffic to the UE during the period via the first BS or the second BS, wherein the period ends when the processor makes a next first determination or a next second determination for the first data bearer of the one or more data bearers; and participate in the data connection based on the first and second determinations by; receiving, during the period, all uplink traffic for the first data bearer according to the corresponding first determination, and transmitting, during the period, all downlink traffic for the first data bearer according to the corresponding second determination; and a memory coupled to the processor. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)

26. An apparatus for wireless communications, comprising:
-
a processor configured to; receive, from a first base station (BS), a first configuration indicating uplink traffic during a period for a first data bearer of one or more data bearers is to be sent via the first BS or a second BS different from the first BS, and downlink traffic during the period for the first data bearer of the one or more data bearers is to be sent via the first BS or the second BS, wherein the uplink and downlink traffic for the first data bearer of the one or more data bearers is independently configured for routing via the first BS or the second BS and wherein the period ends upon receiving a second configuration, different from the first configuration, from the first BS indicating uplink traffic during another period for the first data bearer of the one or more data bearers is to be sent via the first BS or the second BS, and downlink traffic during the other period for the first data bearer of the one or more data bearers is to be sent via the first BS or the second BS; and send, via the first BS or the second BS, a configuration complete message to the first BS in response to the first configuration; and a memory coupled to the processor. - View Dependent Claims (27, 28, 29, 30, 31, 32)
