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.
Claims25
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 user equipment (UE) for wireless communication comprising:
- means for receiving information indicative of a plurality of candidate uplink component carriers in the non-mmW spectrum, each of the plurality of candidate uplink component carriers available to be associated with a particular downlink component carrier in the mmW spectrum;
- means for selecting at least a primary uplink component carrier from the plurality of candidate uplink component carriers in response to receiving the information indicative of the plurality of candidate uplink component carriers;
- and
- means for transmitting a signal to a base station using the primary uplink component carrier.
1 more element
A user equipment (UE) comprising:
- receive circuitry configured to receive mmW signals on one or more downlink mmW carriers;
- memory circuitry configured to store received information indicative of a plurality of candidate uplink component carriers in the non-mmW spectrum, each of the plurality of candidate uplink component carriers available to be associated with a particular downlink component carrier;
- processor circuitry configured to access the information indicative of the plurality of candidate uplink component carriers and to select at least a primary uplink component carrier;
- and
- transmit circuitry configured to transmit a signal to a base station using the primary uplink component carrier.
