Abstract: Methods and apparatuses are provided for receiving system information by a user equipment (UE). System information including first partial bits of a system frame number (SFN) and bandwidth information are received at a first subframe of a radio frame. The system information is identical during a broadcast channel transmission period. Second partial bits of the SFN are acquired having a different value in each of radio frames within the broadcast channel transmission period.

Abstract: Methods and apparatuses are provided for wireless communications. Configuration information including a resource start offset is received. Downlink control information (DCI), transmitted using a first antenna port of a base station on an enhanced physical downlink control channel (EPDCCH) using at least one of control channel elements (CCEs), is received. A resource of a physical uplink control channel (PUCCH) is determined based on a first CCE of the at least one of CCEs, the first antenna port, information in the DCI, and the resource start offset in the configuration information, if a transmission type of the EPDCCH is localized transmission. A hybrid automatic repeat request acknowledgement (HARQ-ACK) signal is transmitted on the resource to the base station.

Abstract: A method and apparatus are described for a User Equipment (UE) to transmit in a control channel ACKnowledgement signals associated with a Hybrid Automatic Repeat reQuest process (HARQ-ACK signals) in response to receiving Transport Blocks (TBs) transmitted from a base station. The UE conveys the HARQ-ACK information by selecting one resource from multiple resources in the control channel and by selecting a constellation point of the modulation scheme for the HARQ-ACK signal. Transmission diversity is supported using different control channel resources that are already available to the UE without configuring additional resources. Design principles are described to optimally map the HARQ-ACK information to control channel resources and modulation constellation points for a Time Division Duplex (TDD) system and for a Frequency Division Duplex (FDD) system.

Abstract: Methods are described for a Node B to transmit and for a User Equipment (UE) to receive ACKnowledgement (ACK) information associated with the use of Hybrid Automatic Repeat reQuest (HARQ), also known as HARQ-ACK signaling, in a communication system that includes multiple downlink component carriers or multiple uplink component carriers. An HARQ-ACK signal to a UE is in response to a data packet transmission from the UE and may consist of 2 information bits when the UE has 2 or more transmitter antennas. The HARQ-ACK signal is always located in the same downlink component carrier as the scheduling assignment resulting to the data packet transmission from the UE.

Abstract: A method apparatus and system for efficiently transmitting and receiving channels are provided in a wireless communication system based on Orthogonal Frequency Division Multiplexing (OFDM). A multiplexing scheme differs according to a channel when a transmitter transmits a packet data channel, a common control channel and a control channel designated for a particular user. Uncoded 1-bit information is broadly dispersed in frequency and time domains using multiplexing technology for maximizing diversity in a channel for transmitting information of at least one bit to a particular user like an acknowledgement (ACK) channel. The transmitter converts a sequence obtained by multiplexing multiple bits to be transmitted to a plurality of users to parallel signals, and broadly disperses the parallel signals in the time and frequency domains. When the uncoded 1-bit information is transmitted, reception reliability is improved because channel coding and transmission are efficiently performed using a small amount of resources.

Abstract: Methods and apparatus are provided for the transmission of physical downlink control signaling. In one method, a User Equipment (UE) receives information associated with a physical resource block (PRB) for enhanced physical downlink control channel (EPDCCH) from a base station. Based on either first information received on physical control format indicator channel (PCFICH) or second information received on higher layer signaling, the UE determines a starting orthogonal frequency division multiple (OFDM) symbol on which EPDCCH transmission starts. The UE receives control information on the EPDDCH based on the information associated with the PRB and the determined starting OFDM symbol.
