Abstract
Official abstract text for this publication.
Disclosed herein are a method and apparatus for requesting scheduling in a wireless communication system. More specifically, a method of requesting scheduling for transmitting uplink data in a wireless communication system may include transmitting, by user equipment (UE), a Scheduling Request (SR) of an SR type selected from multiple SR types to an eNB, receiving, by the UE, an uplink grant determined according to the selected SR type from the eNB, and transmitting, by the UE, uplink data to the eNB through a physical uplink shared channel (PUSCH) resource allocated by the uplink grant.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of requesting, by user equipment (UE), scheduling for transmitting uplink data in a wireless communication system, the method comprising: transmitting, by the UE, a Scheduling Request (SR) of an SR type selected from multiple SR types to an eNB; receiving, by the UE, an uplink grant determined according to the selected SR type from the eNB; and transmitting, by the UE, uplink data to the eNB through a physical uplink shared channel (PUSCH) resource allocated by the uplink grant. 2 . The method of claim 1 , wherein at least one of an index of a physical uplink control channel (PUCCH) resource, an SR periodicity, or an SR subframe offset for sending the SR is differently configured according to each of the multiple SR types. 3 . The method of claim 1 , wherein a size of the uplink data is determined for each of the multiple SR types. 4 . The method of claim 3 , wherein the PUSCH resource allocated by the uplink grant is determined based on the size of the uplink data according to the selected SR type. 5 . The method of claim 3 , wherein a size of a soft buffer set by the eNB is determined based on the size of the uplink data according to the selected SR type. 6 . The method of claim 1 , wherein a resource allocation procedure for sending the uplink data is determined according to the multiple SR types. 7 . The method of claim 1 , further comprising receiving, by the UE, multiple SR configuration information for configuring the multiple SR types from the eNB. 8 . The method of claim 7 , wherein the multiple SR configuration information includes at least any one of information about an index of a PUCCH resource, an SR periodicity, or an SR subframe offset corresponding to each of the multiple SR types. 9 . The method of claim 1 , further comprising: receiving, by the UE, an uplink grant for sending a Buffer Status Report (BSR) from the eNB if the SR is an SR for sending the BSR; and sending, by the UE, the BSR to the eNB through a PUSCH resource allocated by the uplink grant for sending the BSR. 10 . User equipment requesting scheduling for transmitting uplink data in a wireless communication system, comprising: a Radio Frequency (RF) unit for sending and receiving radio signals; and a processor, wherein the processor is configured to: transmit a Scheduling Request (SR) of an SR type selected from multiple SR types to an eNB, receive an uplink grant determined according to the selected SR type from the eNB, and transmit uplink data to the eNB through a physical uplink shared channel (PUSCH) resource allocated by the uplink grant.
