Abstract
A technique for transmitting uplink scheduling grant information (702) from a network node to a wireless device in unlicensed spectrum is described. As to a method aspect of the technique, a listen before talk (LBT) process is performed (202) on each of at least one carrier in the unlicensed spectrum. The uplink scheduling grant information is transmitted (304) on one of the at least one carrier in response to a positive result of the LBT process on the one carrier. The uplink scheduling grant information (702) is indicative of an uplink scheduling grant on multiple carriers in the unlicensed spectrum.
Claims17
A method of transmitting uplink scheduling grant information from a network node to a wireless device in unlicensed spectrum, the method comprising:
- performing a listen before talk (LBT) process on each of at least one carrier in the unlicensed spectrum;
- transmitting the uplink scheduling grant information on one of the at least one carrier in response to a positive result of the LBT process on the one carrier, the uplink scheduling grant information being indicative of an uplink scheduling grant on multiple carriers in the unlicensed spectrum;
- determining a metric for a plurality of carriers available in the unlicensed spectrum;
- and
- selecting the multiple carriers based on the metric.
A non-transitory computer readable recording medium storing a computer program product for controlling transmission of uplink scheduling grant information from a network node to a wireless device in unlicensed spectrum, the computer program product comprising software instructions which, when run on processing circuitry of one or more computing devices, causes the one or more computing devices to:
- perform a listen before talk (LBT) process on each of at least one carrier in the unlicensed spectrum;
- transmit the uplink scheduling grant information on one of the at least one carrier in response to a positive result of the LBT process on the one carrier, the uplink scheduling grant information being indicative of an uplink scheduling grant on multiple carriers in the unlicensed spectrum;
- determine a metric for a plurality of carriers available in the unlicensed spectrum;
- and
- select the multiple carriers based on the metric.
A device for transmitting uplink scheduling grant information from a network node to a wireless device in unlicensed spectrum, the device comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the device is operative to:
- perform a listen before talk (LBT) process on each of at least one carrier in the unlicensed spectrum;
- transmit the uplink scheduling grant information on one of the at least one carrier in response to a positive result of the LBT process on the one carrier, the uplink scheduling grant information being indicative of an uplink scheduling grant on multiple carriers in the unlicensed spectrum;
- determine a metric for a plurality of carriers available in the unlicensed spectrum;
- and
- select the multiple carriers based on the metric.
