Transmission of scheduling assignments in multiple operating bandwidths

摘要

Methods and apparatuses are described for the transmission of Scheduling Assignments (SAs) from a base station to User Equipments (UEs) for data reception in the downlink or data transmission in the uplink of a communication system consisting of multiple Component Carriers (CCs). The SAs are separately coded and transmitted using elementary units (Control Channel Elements or CCEs). Locations of CCEs determine whether an SA is intended for a first CC or for a second CC. Further, the location of CCEs for an SA intended for a first CC is used to determine locations of CCEs for an SA intended for a second CC.

主权项

1. A method for transmitting a plurality of scheduling assignments (SA) through a downlink control channel in a wireless communication system supporting carrier aggregation, the method comprising the steps of:
transmitting to a user equipment (UE) a first SA for a first Component Carrier (CC) using a first set of Control Channel Elements (CCEs); and transmitting to the UE a second SA for a second CC using a second set of CCEs, wherein a second set of CCEs is positioned away by a predetermined number of CCEs relative to the first set of CCEs, and the predetermined number of CCEs correspond to a value of a CC indicator.
