摘要:
A method and apparatus for mitigating interference in a wireless communication system supporting heterogeneous networks are disclosed. When the wireless communication system includes a first network and a second network, the method includes generating information indicating whether each of uplink component carriers is used for transmission of control information in the first network, and transmitting the information to a UE. A component carrier used for transmission of control information in the first network is different from a component carrier used for transmission of control information in the second network.

Provided are a method and an apparatus for applying control information in a wireless communication system. The method includes the steps of: receiving a setting for ACK/NACK(acknowledgement/not-acknowledgement) repetition from a base station; receiving control information to be applied at a particular time point from the base station; transmitting ACK/NACK for the control information; and performing an operation according to the control information at the particular time point when the transmitted ACK/NACK is ACK, wherein the operation at the particular time point is applied to a subframe which is determined according to the setting for ACK/NACK repetition.

Disclosed are a method and a device for transmitting an ACK/NACK in a time division duplex (TDD)-based wireless communication system. A terminal receives an uplink grant that includes uplink resource allocation and piggyback information, and determines an ACK/NACK response for at least one downlink transmission block according to said piggyback information. The terminal multiplexes the ACK/NACK response with an uplink transport block and transmits the multiplexed ACK/NACK response.

Disclosed are a multi-carrier supporting method and apparatus. A terminal receives information on at least one allocated component carrier from among a plurality of component carriers from a base station, and receives activation control information on an active component carrier that is activated from among the at least one allocated component carrier via a downlink control channel. The terminal transmits a reception acknowledgement for the activation control information via an uplink control channel.

A method and apparatus for transmitting reception acknowledgment for hybrid automatic repeat request (HARQ) in a wireless communication system are provided. A user equipment receives a plurality of downlink resource allocations on a plurality of downlink control channels by using a plurality of downlink carriers, and receives a plurality of downlink transfer blocks on a plurality of downlink shared channels indicated by the plurality of downlink resource allocations. The user equipment determines a plurality of acknowledgment (ACK)/negative acknowledgment (NACK) resource indices based on a plurality of resource indices obtained from downlink resources which use the plurality of downlink control channels. The user equipment transmits ACK/NACK for the plurality of downlink transfer blocks by using ACK/NACK resources indicated by the plurality of ACK/NACK resource indices.

A method of transmitting a control signal using efficient multiplexing is disclosed. The present invention includes the steps of multiplexing a plurality of 1-bit control signals within a prescribed time-frequency domain by code division multiple access (CDMA) and transmitting the multiplexed control signals, wherein a plurality of the 1-hit control signals include a plurality of the 1-bit control signals for a specific transmitting side. Accordingly, reliability on 1-bit control signal transmission can be enhanced.
摘要:
A method for performing a wireless communication between a UE and a BS in a wireless communication system supporting a first UE using a single frequency band and a second UE using a plurality of frequency bands, to each of which OFDM is applied, is disclosed. The method includes being allocated one or more downlink component carriers for the second UE from the BS, and receiving the one or more downlink component carriers from the BS by the second UE. The one or more downlink component carriers are cyclically shifted by different cyclic shift values and the cyclic shifting is performed by multiplying each of the one or more downlink component carriers by a linear phase having a different inclination.
