1. A method of wireless communication performed by a user equipment, comprising:
receiving a configuration for time division multiplexed uplink carrier aggregation of a first time division duplex carrier with a second time division duplex carrier, wherein a bandwidth of the second time division duplex carrier is lower than a bandwidth of the first time division duplex carrier, wherein the configuration indicates a frame structure corresponding to the second time division duplex carrier, and wherein the frame structure comprises a 2.5 millisecond single cycle slot sequence including:
a first downlink sequence including two consecutive downlink slots,
a first special sequence following the first downlink sequence, wherein the first special sequence includes one special slot, wherein the special slot supports uplink transmissions, and
a first uplink sequence following the first special sequence, wherein the first uplink sequence includes two consecutive uplink slots; and
communicating in accordance with the configuration.
