Abstract
Methods, systems, and devices for wireless communication are described. Downlink carriers in the millimeter wave spectrum may be paired with one or more carriers in a lower frequency spectrum, such as one or more uplink carriers in a sub-6 GHz band.
Claims50
A method of wireless communication performed by a user equipment (UE) in communication with a base station, the method comprising:
- receiving information indicative of a plurality of candidate uplink component carriers in the non-mmW (millimeter wave) spectrum, each of the plurality of candidate uplink component carriers available to be associated with a particular downlink component carrier in the mmW spectrum;
- in response to receiving the information indicative of the plurality of candidate uplink component carriers, selecting at least a primary uplink component carrier from the plurality of candidate uplink component carriers;
- and
- transmitting a signal to the base station using the primary uplink component carrier.

A method of wireless communication performed by a user equipment (UE) in communication with a base station, the method comprising:
- receiving information indicative of an initial configured primary uplink component carrier from the base station, wherein the initial configured primary uplink component carrier is a non-mmW carrier paired with a particular downlink mmW carrier;
- transmitting a UE capability report to the base station using the initial configured primary uplink component carrier, wherein the UE capability report includes UE uplink carrier capability information;
- and
- receiving a configuration of one or more secondary uplink component carriers associated with the particular downlink mmW carrier from the base station in response to the UE capability report.
