Decoupled downlink reception and uplink reception in a mixed licensed carrier and unlicensed carrier wireless communication system

A wireless device for providing decoupling of downlink reception and uplink transmission in a mixed licensed carrier and unlicensed carrier wireless communications system, comprising:

• a transceiver;
• at least one processor;
• and
• memory comprising instructions executable by the at least one processor whereby the wireless device is operable to:
• communicate with a first radio node that operates on a first carrier frequency in a licensed band to obtain a set of time resources in which the wireless device is expected to be scheduled for uplink data transmission on the first carrier frequency and/or a set of time resources in which the wireless device is expected to receive downlink control transmission on the first carrier frequency;
• communicate with a second radio node that operates on a second carrier frequency in an unlicensed band to obtain, based on the set of time resources in which the wireless device is expected to be scheduled for uplink data transmission on the first carrier frequency and/or the set of time resources in which the wireless device is expected to receive downlink control transmission on the first carrier frequency, a set of time resources in which the wireless device will not be scheduled for downlink reception on the second carrier frequency;
• and
• receive a downlink data transmission from the second radio node on the second carrier frequency in a time resource that is not in the set of time resources in which the wireless device will not be scheduled for downlink reception on the second carrier frequency.

A radio node for providing decoupling of downlink reception and uplink transmission in a mixed licensed carrier and unlicensed carrier wireless communications system, comprising:

• at least one processor;
• and
• memory comprising instructions executable by the at least one processor whereby the radio node is operable to:
• communicate with a wireless device to agree, based on a set of time resources in which the wireless device is expected to be scheduled for uplink data transmission to another radio node on a first carrier frequency in a licensed band and/or a set of time resources in which the wireless device is expected to receive downlink control transmission on the first carrier frequency, a set of time resources in which the wireless device will not be scheduled for downlink reception from the radio node on a second carrier frequency in an unlicensed band;
• and
• transmit a downlink data transmission to the wireless device on the second carrier frequency in a time resource that is not in the set of time resources in which the wireless device will not be scheduled for downlink reception on the second carrier frequency.
