Abstract
A method performed by a wireless device in a wireless communication system, the method including detecting a first subframe, wherein the first subframe includes a first slot and a second slot, and wherein orthogonal frequency division multiplexing (OFDM) symbols in the first slot are not occupied, detecting a second subframe, wherein the second subframe a next subframe of the first subframe, and wherein all OFDM symbols in the second subframe are occupied and receiving a downlink signal from a network on an unlicensed carrier via at least one of the first subframe and the second subframe.
Claims14
A method performed by a wireless device in a wireless communication system, the method comprising:
- detecting that a first subframe on an unlicensed carrier is a partial subframe in which a part of orthogonal frequency division multiplexing (OFDM)
- symbols are unoccupied according to an indication in downlink control information (DCI) received from a network;
- detecting that a second subframe next to the first subframe on the unlicensed carrier is a full subframe in which all OFDM symbols are occupied based on detecting that the first subframe is the partial subframes;
- and
- performing a downlink reception from the network on the unlicensed carrier via at least one of the first subframe and the second subframe.
A wireless device in a wireless communication system, the wireless device comprising:
- a memory;
- a transceiver;
- and
- at least one processor, coupled to the memory and the transceiver, and configured to:
- detect that a first subframe on an unlicensed carrier is a partial subframe in which a part of orthogonal frequency division multiplexing (OFDM)
- symbols are unoccupied according to an indication in downlink control information (DCI) received from a network;
- detect that a second subframe next to the first subframe on the unlicensed carrier is a full subframe in which all OFDM symbols are occupied based on detecting that the first subframe is the partial subframe;
- and
- control the transceiver to perform a downlink reception from the network on the unlicensed carrier via at least one of the first subframe and the second subframe.
A processor for a wireless device in a wireless communication system, wherein the processor is configured to:
- detect that a first subframe on an unlicensed carrier is a partial subframe in which a part of orthogonal frequency division multiplexing (OFDM)
- symbols are unoccupied according to an indication in downlink control information (DCI) received from a network;
- detect that a second subframe next to the first subframe on the unlicensed carrier is a full subframe in which all OFDM symbols are occupied based on detecting that the first subframe is the partial subframe;
- and
- control the transceiver to perform a downlink reception from the network on the unlicensed carrier via at least one of the first subframe and the second subframe.
