Abstract
A communication device for handling a transmission in an unlicensed band comprises a storage unit for storing instructions and a processing circuit coupled to the storage unit. The process sing circuit is configured to execute the instructions stored in the storage unit. The instructions comprise receiving a configuration for an occupancy of an unlicensed band; performing a clear channel assessment (CCA) in a time interval of the unlicensed band; performing an uplink (UL) transmission in a first subframe of the unlicensed band according to a result of the CCA; and transmitting a reservation signal near a boundary of the first subframe according to the configuration.
Claims23
A communication device for handling a transmission in an unlicensed band, comprising:
- a storage unit, for storing instructions of:
- receiving a configuration for an occupancy of an unlicensed band;
- performing a clear channel assessment (CCA) in a time interval of the unlicensed band;
- performing an uplink (UL) transmission in a first subframe of the unlicensed band according to a result of the CCA;
- determining whether to transmit a reservation signal near a boundary of the first subframe according to the configuration;
- transmitting the reservation signal at an end of the first subframe, at a start of a second subframe after the first subframe, at an end of a third subframe before the first subframe or in at least one subframe before the first subframe, according to the configuration after performing the CCA;
- and
- not transmitting the reservation signal according to the configuration, when the configuration instructs the communication device not to transmit the reservation signal;
- and
- a processing circuit, coupled to the storage unit, configured to execute the instructions stored in the storage unit.
A method for handling a reception in an unlicensed band, comprising:
- a network transmitting a configuration for an occupancy of an unlicensed band to a communication device;
- the network determining whether to transmit a reservation signal near a boundary of a first subframe according to the configuration;
- the network transmitting the reservation signal at an end of the first subframe, at a start of a second subframe after the first subframe or at an end of a third subframe before the first subframe according to the configuration;
- the network not transmitting the reservation signal, when the configuration instructs the network not to transmit the reservation signal;
- and
- the network performing an uplink (UL) reception in the first subframe of the unlicensed band from the communication device, after transmitting the reservation signal or a downlink (DL) subframe.
A network for handling a reception in an unlicensed band, comprising:
- a storage unit, for storing instructions of:
- transmitting a configuration for an occupancy of an unlicensed band to a communication device;
- determining whether to transmit a reservation signal near a boundary of a first subframe according to the configuration;
- transmitting the reservation signal at an end of the first subframe, at a start of a second subframe after the first subframe or at an end of a third subframe before the first subframe according to the configuration;
- not transmitting the reservation signal, when the configuration instructs not to transmit the reservation signal;
- and
- performing an uplink (UL) reception in the first subframe of the unlicensed band from the communication device, after transmitting the reservation signal or a downlink (DL) subframe;
- and
- a processing circuit, coupled to the storage unit, configured to execute the instructions stored in the storage unit.
