摘要:
A photoresist polymer includes a first repeating unit and a second repeating unit. The first repeating unit includes a fluorine leaving group that is configured to be removed by a photo-chemical reaction. The second repeating unit includes a silicon-containing leaving group that is configured to be removed by the fluorine leaving group when the fluorine leaving group is removed from the first repeating unit.
摘要:
A method for allocating physical resources to an Acknowledgement (ACK)/Negative Acknowledgement (NACK) signal channel representative of a response signal in a wireless communication system. The method includes grouping ACK/NACK signal channels corresponding to a plurality of resource blocks used for transmission of a data channel or a control channel into a plurality of groups so ACK/NACK signal channels having consecutive indexes do not belong to the same group; and allocating same frequency resources to ACK/NACK signal channels belonging to the same ACK/NACK signal channel group and allocating orthogonal sequences so ACK/NACK signal channels in each ACK/NACK signal channel group are distinguished in a code domain.

A transmission/reception method and apparatus for a mobile communication system supporting uplink MIMO is provided. In the transmission method, a User Equipment (UE) transmits two transport blocks according to a predetermined number of layers and respective precoding indices, an evolve Node B (eNB) transmits, when one of the transport blocks is lost, a negative acknowledgement for the lost transport block, and the UE sets a precoding index for the lost transport block to a predetermined value to retransmit the lost transport block while maintaining the number of layers.

A method and system are provided for controlling uplink transmission power in a wireless communication system. At least one of a plurality of downlink carriers and a plurality of uplink carriers are aggregated, and the plurality of downlink carriers and the plurality of uplink carriers are mapped between a User Equipment (UE) and a network in the wireless communication system. A message relating to uplink carrier transmission power is received at the UE from the network via a downlink carrier. Uplink transmission power of one or more uplink carriers is controlled in accordance with the message and aggregation and mapping of at least one of the downlink carrier and the one or more uplink carriers.

A user equipment (UE) is configured to communicate with a plurality of base stations in a wireless network. The UE includes a processor that receive a downlink grant scheduling a physical downlink shared channel (PDSCH) for the UE, the downlink grant being transmitted in a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (ePDCCH). The processor also receives UE-specific demodulation reference signals (UE-RS) provided for demodulation of the PDSCH, wherein the UE-RS are scrambled according to a scrambling sequence initialized with an initialization value cinit. The downlink grant includes a one-bit scrambling identifier (SCID) information field configured to indicate a pair of values comprising a scrambling identifier nSCID and a virtual cell ID Nv-IDcell out of two candidate pairs, the pair of values to be used for determining the initialization value cinit for the UE-RS.

A method is provided for controlling retransmission by a User Equipment (UE) in a wireless communication system supporting Multiple Input Multiple Output (MIMO) technology. A plurality of transport blocks is initially transmitted to a Node B. A retransmission request for at least one transport block among the plurality of transport blocks is received from the Node B. A precoding matrix for retransmission of the at least one transport block is determined based on the retransmission request for the at least one transport block. The at least one transport block is retransmitted using the determined precoding matrix.

Methods and apparatus are provided for transmitting and receiving reference signals through distributed antennas deployed within a service area of a base station in a mobile communication system. First control information, including at least two scrambling factor combinations, is received at a terminal from the base station. Second control information, indicating one of the at least two scrambling factor combinations, is received at the terminal from the base station. The one of the at least two scrambling factor combinations is selected based on the second control information. An initial value of a demodulation reference signal sequence is calculated using the selected scrambling factor combination. The demodulation reference signal sequence is received using the initial value.

A method for transmitting and receiving a control channel message in a mobile communication system using multiple antennas is provided. A base station determines whether a common pilot is used or a dedicated pilot is used. It also determines whether a corresponding Multiple Input Multiple Output (MIMO) mode is a Multi-CodeWord (MCW) MIMO mode or a Single CodeWord (SCW) MIMO mode, and determines whether knockdown precoding is used or ready-made precoding is used. The base station generates a control channel message field including a pilot pattern and a precoding type according to the determination results, and transmits the generated control channel message to the terminal. The terminal receives a control channel message transmitted from a base station. The terminal determines whether a common pilot is used or a dedicated pilot is used, whether a corresponding MIMO mode is an MCW MIMO mode or an SCW MIMO mode, and whether knockdown precoding is used or ready-made precoding is used. The terminal analyzes the control channel message field according to the determination results, and determines a data reception method according to the analysis result.
