The present invention relates to a method for transmitting an uplink or downlink grant in a wireless communication system that supports uplink and downlink multiple input multiple output (MIMO) schemes. The method comprises: determining a downlink control information (DCI) format for an uplink or downlink grant to generate control information: attaching a cyclic redundancy check (CRC) for detecting an error in the created control information; and channel-coding the CRC-attached control information, wherein the control information comprises a bit flag for distinguishing whether the grant is an uplink grant or a downlink grant.

The present invention relates to a method and device for sending and receiving control data on a wireless communications system employing an aggregated carrier arrangement. In a method for transmitting control data on a wireless communications system supporting carrier aggregation according to one aspect of the present invention, a base station transmits, to a mobile station, information relating to physical cell ID (physical cell identification, hereinafter “PCI”) for use in uplink signal transmission, and receives an uplink signal generated from the mobile station using the PCI.

There is provided a method for allocating subframes in a radio communications system that performs communication by using a radio frame including a plurality of subframes, the method including: selecting a backhaul downlink subframe in which a base station is to transmit a signal to a relay station; and allocating the backhaul downlink subframe to a substitution subframe which is not limitation subframes, when the selected backhaul downlink subframe corresponds to one of the limitation subframes, wherein the limitation subframes are subframes in which the relay station is to transmit essential information to a relay user equipment. Therefore, it is possible to overcome a limitation that is present in a link between the base station and the relay station, perform an HARQ operation, and improve the efficiency of radio resource allocation.

A method for transmitting ACK/NACK (Acknowledgement/Negative ACK) signals in a wireless communication system is disclosed. The method comprises receiving a plurality of data blocks from a base station; generating ACK/NACK signals corresponding to the plurality of data blocks; allocating resources for transmitting ACK/NACK signals, wherein the resources are allocated independently per slot; and transmitting the ACK/NACK signals through one uplink component carrier by using the allocated resources. Preferably, the step of allocating resources includes allocating the resources to minimize the difference in the number of the ACK/NACK signals transmitted per slot.

The present invention relates to a method and to an apparatus for supporting carrier aggregation. More particularly, the present invention relates to a method for enabling user equipment to receive a signal from a base station in a wireless communication system which supports carrier aggregation, wherein said the method comprises the steps of: setting a first component carrier to a paused state; receiving state change information for the first component carrier via the second component carrier during the paused state of the first component carrier; and monitoring a control channel via the first component carrier if the state change information indicates a predetermined value. The present invention also relates to an apparatus for the method.
摘要:
The method for wireless resource subframe allocation comprises the following steps: allocation of the control channel based on the first RAT (Radio Access Technology) of the first control domain, which includes the OFDM symbol of the first number from the sub-frame containing multiple OFDM symbols and multiple subcarriers in the frequency domain; allocation of the control channel based on the second RAT of the second control domain including the OFDM symbol of the second number which follows said first control domain; and the allocation of a data channel in the data domain which includes the OFDM symbols positioned outside said first control domain and second control domain. This invention provides a sub-frame structure which is compatible with existing wireless communication systems. This method allows the continued use of existing control channel systems or base signal structures. The method is also capable of supporting advanced features.
