Abstract:
1. A method comprising: a first base station serving a user equipment device (UE) in a connected state over a first time division duplex (TDD) air interface defining a first TDD frame arrangement, wherein the first TDD frame arrangement defines a first downlink-uplink sequence; the first base station receiving from the UE in an uplink transmission on the first TDD air interface a report of a second TDD frame arrangement used by a second base station on a second TDD air interface, wherein the second TDD frame arrangement defines a second downlink-uplink sequence and is different than the first TDD frame arrangement in at least one respect selected from the group consisting of (i) the second downlink-uplink sequence being different than the first downlink-uplink sequence and (ii) the first TDD frame arrangement and second TDD frame arrangement being unsynchronized with each other in time; and based at least in part on the received report of the second TDD frame arrangement used by the second base station, the first base station avoiding downlink transmission of bearer traffic to the UE during times when the second TDD frame arrangement defines uplink transmission, while continuing to serve the UE in the connected state.
