Abstract
A method and apparatus for handling overlap of multiple channels in a wireless communication system is provided. A user equipment (UE), which operates in half-duplex frequency division duplex (FDD), determines that a periodic uplink (UL) transmission collides with a physical downlink shared channel (PDSCH) reception in a subframe, and performs either the periodic UL transmission or the PDSCH reception in the subframe. When the periodic UL transmission corresponds to a semi-persistent scheduled (SPS) physical uplink shared channel (PUSCH), the PDSCH reception is performed.
Claims14
A method performed by a wireless device in a wireless communication system, the method comprising:
- identifying a first subframe in which a periodic uplink (UL) transmission is scheduled, wherein the periodic UL transmission comprises a UL transmission which is based on a semi-persistent scheduling (SPS);
- identifying a second subframe in which a physical downlink shared channel (PDSCH) reception is scheduled;
- comparing a priority of the periodic UL transmission with a priority of the PDSCH reception, based on the second subframe being identical to the first subframe;
- and
- based on a result of the comparison, performing one of the periodic UL transmission or the PDSCH reception and dropping the other one of the periodic UL transmission or the PDSCH reception,
- wherein the wireless device operates in a half-duplex frequency division duplex (FDD).
A wireless device in a wireless communication system, the wireless device comprising:
- a memory;
- a transceiver;
- and
- at least one processor operatively coupled to the memory and the transceiver, wherein the at least one processor is configured to:
- identify a first subframe in which a periodic uplink (UL) transmission is scheduled, wherein the periodic UL transmission comprises a UL transmission which is based on a semi-persistent scheduling (SPS);
- identify a second subframe in which a physical downlink shared channel (PDSCH) reception is scheduled;
- compare a priority of the periodic UL transmission with a priority of the PDSCH reception, based on the second subframe being identical to the first subframe;
- and
- based on a result of the comparison, perform one of the periodic UL transmission or the PDSCH reception and drop the other one of the periodic UL transmission or the PDSCH reception,
- wherein the wireless device operates in a half-duplex frequency division duplex (FDD).
