Abstract:
Disclosed are a terminal device for receiving a signal in a wireless communication system for supporting a plurality of component carriers and a method thereof. In the terminal device for receiving the signal in the system for supporting the component carriers, a receiver receives a Physical Downlink Control Channel (PDCCH) including control information of a first type component carrier from a base station or a relay. A processor performs a decoding operation or controls an operation in a slip mode on the basis of control information included in a PDCCH in a second type component carrier after a time corresponding to a particular time offset value passes from a transmission time point of the PDCCH.

A method for efficiently transmitting and receiving a paging message and system information from and in a mobile station of a broadband wireless access system is disclosed. A method for receiving a paging message in a mobile station comprises receiving paging information from a serving base station, the paging information including paging sub group identifier (paging sub group ID) indicating a paging sub group to which the mobile station belongs; and receiving the paging message for a predetermined paging interval of the paging sub group, wherein the paging sub group is determined separately from a paging group and a geographical location determining the paging group, and is maintained while the mobile station is being operated in an idle mode.
Abstract:
According to one embodiment, a method of allocating a radio resource for a relay station includes: transmitting configuration information through a higher layer signal, the configuration information including information regarding an OFDM symbol at which a relay zone begins; allocating the relay zone to the relay station in a subframe based on the configuration information; and transmitting a relay control channel to the relay station in the relay zone. The subframe includes OFDM symbols in a time domain and subcarriers in a frequency domain. The relay zone includes a subset of the OFDM symbols in the time domain and a portion of the subcarriers in the frequency domain. The configuration information indicates an OFDM symbol from among a second OFDM symbol, a third OFDM symbol and a fourth OFDM symbol. The relay control channel is transmitted from the fourth OFDM symbol of the subframe.

Abstract:
Disclosed are a repeater for receiving signals from a base station in a wireless communication system, and a signal receiving method. The base station reports, to each repeater, information on the aggregation level of a relay-control channel element (R-CCE) of a relay-physical downlink control channel (R-PDCCH) via an explicit signaling method or implicit signaling method. In the event the base station reports via an explicit signaling method, the repeater receives, from the base station, information on the aggregation level of R-CCE which is a transmission unit of R-PDCCH, wherein the information contains control information for the repeater. Then, the repeater decodes an R-PDCCH region on an R-CCE aggregation level basis in accordance with the received R-CCE aggregation level information.
Abstract:
Disclosed are an apparatus and a method for transmitting/receiving control information in a wireless communication system. In a repeater according to the present invention, a receiving antenna can receive control information for a hybrid automatic repeat reQuest ACKnowledgement (HARQ ACK) feedback on the data transmission of a base station from the base station through higher layer signaling. On the basis of the control information, a processor can determine a resource in an upper link control channel to be used for the transmission of the HARQ feedback. A transmitting antenna can transmit the HARQ feedback to the base station through the resource that has been determined.
Abstract:
The present invention relates to a relay node device for receiving control information from a base station and a method therefor. The relay node device according to the present invention comprises: a receiver, which receives information about an area where a relay-physical downlink control channel (R-PDCCH), the channel for transmitting control information for the relay node from a base station, is allocated; a processor, which searches for at least one R-PDCCH for the relay node based on the R-PDCCH allocation information received; and an R-PDCCH receiver, which receives the at least one R-PDCCH from the fourth symbol of the first slot in a downlink backhaul subframe of the area where the at least one R-PDCCH searched for by the processor has been allocated.
Abstract:
The invention relates to a method of transmitting an uplink signal at a communication apparatus in a wireless communication system. The wireless communication system can receive pattern information of downlink subframes for a base station (BS)-to-the communication apparatus transmission as a bitmap; receive resource block (RB) information associated with a control channel for the BS-to-the communication apparatus transmission; receive the control channel from a fourth orthogonal frequency division multiplexing (OFDM) symbol of the downlink subframe n corresponding to a downlink subframe index n based on the RB information and the pattern information, the downlink subframe n comprising at least one downlink subframe other than downlink subframe 0, downlink subframe 4, downlink subframe 5 and downlink subframe 9; receive a data channel in the downlink subframe n; and transmit feedback information associated with the data channel to the BS via an uplink subframe for the communication apparatus-to-the BS transmission.
Abstract:
A method of transmitting uplink control information by a relay node includes: receiving resource allocation information and sequence information in accordance with a predetermined physical uplink control channel (PUCCH) transmission format for the relay node from an eNode B; and transmitting a PUCCH, to which a sequence corresponding to the sequence information is applied, to the eNode B through a predetermined number of symbols in a second slot of a resource region indicated by the resource allocation information. The predetermined PUCCH transmission format includes: a first format for transmitting ACK/NACK information indicating success or failure of reception of a codeword received from the eNode B; a second format for transmitting channel quality information (CQI) indicating a channel quality state; and a third format for transmitting a scheduling request (SR) signal. A resource for PUCCH transmission format for a user equipment is reused for transmission of the predetermined PUCCH transmission format.
