Abstract

The invention relates to a method for supporting transmission of a scheduling request in user equipment in an enhanced carrier aggregation system. The method comprises the following steps of receiving signaling for indicating configuration of dedicated scheduling request resources of the user equipment, wherein the user equipment supports the transmission of the scheduling request on physical uplink control channels (PUCCH) on secondary cells (SCell); and determining a change of state of activation / deactivation of a first secondary cell for configuring the scheduling request resources on the physical uplink control channel and determining a transmission method for the scheduling request of the user equipment based on the change of state. The configuration of the dedicated scheduling request resources is one of the following configurations that the dedicated scheduling request resources are only configured on a PUCCH of a primary cell (PCell), the dedicated scheduling request resources are only configured on the PUCCH of one secondary cell (SCell), the dedicated scheduling request resources are configured on the PUCCHs of a plurality of secondary cells (SCell) and the dedicated scheduling request resources are configured on the PUCCH of the primary cell (PCell) and the PUCCH of one or more of secondary cells (SCell).

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more particularly, to a method for supporting scheduling request transmission in a user equipment in an enhanced carrier aggregation system and a method for configuring a base station in an enhanced carrier aggregation system A method of scheduling request transmission for user equipment. Background technique [0002] In RAN#66, a consensus has been reached that the carrier aggregation user equipment supports the transmission of the physical uplink control channel PUCCH on the secondary cell SCell. UCI (Uplink Control Information) transmitted on the Physical Uplink Control Channel PUCCH includes Scheduling Request (SR), CQI (Channel Quality Index: Channel Quality Index) and ACK / NACK. Issues related to the physical layer specification of the physical uplink control channel PUCCH have been discussed in RAN1, such as CQI and ACK / NACK related content. Next, the required L...
