Abstract
In order to reduce latency in new radio access technology (NR), a method and apparatus for configuring a pre-scheduled physical uplink shared channel (PUSCH) is proposed. A user equipment (UE) receives a configuration of the pre-scheduled PUSCH from a network, wherein the configuration includes a percentage of resource for the pre-scheduled PUSCH, and transmits UL data via the pre-scheduled PUSCH according to the percentage of resource to the network. Further, the UE receives a dynamic indication of adjusting the percentage of resource for the pre-scheduled PUSCH from the network, and transmits UL data via the pre-scheduled PUSCH according to the adjusted percentage of resource to the network.
Claims13
A method for configuring a pre-scheduled physical uplink shared channel (PUSCH) by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving a configuration of the pre-scheduled PUSCH from a network, wherein the configuration includes a percentage of resource for the pre-scheduled PUSCH;
- transmitting UL data via the pre-scheduled PUSCH according to the percentage of resource to the network;
- receiving a dynamic indication of adjusting the percentage of resource for the pre-scheduled PUSCH from the network;
- and
- transmitting UL data via the pre-scheduled PUSCH according to the adjusted percentage of resource to the network,
- wherein the indication indicates that the percentage of resource for the pre-scheduled PUSCH is decreased, and
- wherein a highest or lowest physical resource block (PRB) is selected.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a memory;
- a transceiver;
- and
- a processor, coupled to the memory and the transceiver, that:
- controls the transceiver to receive a configuration of a pre-scheduled physical uplink shared channel (PUSCH) from a network, wherein the configuration includes a percentage of resource for the pre-scheduled PUSCH,
- controls the transceiver to transmit UL data via the pre-scheduled PUSCH according to the percentage of resource to the network,
- controls the transceiver to receive a dynamic indication of adjusting the percentage of resource for the pre-scheduled PUSCH from the network, and
- controls the transceiver to transmit UL data via the pre-scheduled PUSCH according to the adjusted percentage of resource to the network,
- wherein the indication indicates that the percentage of resource for the pre-scheduled PUSCH is decreased, and
- wherein a highest or lowest physical resource block (PRB) is selected.
