    摘要: A communications device transmits/receives data from/to a mobile communications network including one or more network elements arranged to form a wireless access interface for transmitting/receiving data. An up-link includes a control channel for transmitting signalling information from the communications device to the mobile communications network in accordance with a predetermined format in which signals which representing the signalling information occupy, in the time domain, the predetermined number of frequency division multiplexed symbols of the control channel. A controller is configured to control a transmitter unit to transmit the signals and a receiver unit to receive the signals to transmit or receive the data. The controller is configured to adapt the transmission of the signals representing the signalling information transmitted, by the transmitter unit, in the control channel to occupy a smaller number of the predetermined number of frequency division multiplexed symbols of the time period of the control channel.

    摘要: The present invention relates to a wireless communication system, and more particularly, to an uplink control information transmitting/receiving method and device. A method for a terminal to transmit acknowledgement information in a wireless communication system according to an embodiment of the present invention includes: determining whether the transmission of a scheduling request is set in one uplink subframe, where acknowledgement information on downlink transmission in a downlink subframe set including M(M≥1) downlink subframes is to be transmitted; determining a Physical Uplink Control Channel (PUCCH) format and a resource with which the acknowledgement information is to be transmitted; and transmitting the acknowledgement information by using the PUCCH format and the resource. Here, if the transmission of the scheduling request is set in the one uplink subframe, there is no Semi-Persistent Scheduling (SPS) releasing Physical Downlink Control Channel (PDCCH) in the downlink subframe set. If the acknowledgement information corresponds to only one Physical Downlink Shared Channel (PDSCH) indicated by the detection of a corresponding Physical Downlink Control Channel (PDCCH) received on only a Primary Cell (PCell) in the downlink subframe set, and a Downlink Assignment Index (DAI) value of the PDCCH is 1, the acknowledgement information and the scheduling request may be transmitted using PUCCH format 1b.

    摘要: A transmission apparatus and method for a communication system based on Orthogonal Frequency Division Multiplexing-Code Division Multiplexing (OFDM-CDM). A frequency spreader multiplies symbols to be transmitted by a frequency spreading factor and outputs frequency spread symbols whose number corresponds to the frequency spreading factor. Buffers whose number corresponds to the frequency spreading factor temporarily store the frequency spread symbols in a unit of a predefined number of symbols. A time spreader multiplies parallel frequency spread symbols from the buffers by a time spreading factor and outputs frequency-time spread symbols. An Inverse Fast Fourier Transform (IFFT) processor performs IFFT on the frequency-time spread symbols, and outputs an OFDM symbol. A Guard Interval (GI) inserter inserts a GI into a signal output from the IFFT processor and transmits the signal. The system can obtain complete diversity gain and residual gain due to the effect of a time-varying channel in any channel environment.

    摘要: A wireless transmitter comprising an encoder for encoding a set of information bits to provide a set of code symbols at a data rate. A demultiplexer provides the set of code symbols in first and second code symbol subsets, each having different code symbol rates, to first and second modulators, wherein the data rate is equal to a combination of the different code symbol rates. The first and second modulators respectively modulate the first and second code symbol subsets according to first and second code symbol rate formats, respectively, wherein the different code symbol rates have a ratio equal to a number other than one, to provide a modulated first code symbol subset and a second code symbol subset. A transmission subsystem provides the modulated first code symbol subset on a first carrier frequency and the modulated second code symbol subset on a second carrier frequency.

    摘要: A method of an apparatus for transmitting data in a multiple carrier system comprises encoding data and dividing the resulting encoded symbols for transmission on different frequencies. The transmitter comprises a control processor (50) for determining the capacity of each of a plurality of channels and selecting a data rate for each channel depending on the determined capacity. A plurality of transmission subsystems (56 to 72) are responsive to the control processor (50). Each transmission subsystem is associated with a respective one of the plurality of channels for scrambling encoded data with codes unique to the channel for transmission in the channel. A variable demultiplexer (56) under the control of the control processor (50) demultiplexes the encoded data into the plurality of transmission subsystems at a demultiplexing rate derived from the data rates selected for the channels by the controller. In one embodiment of the transmission subsystems, the encoded symbols are provided to a symbol repetition unit (58) which keeps the symbol rate of data to be transmitted fixed. In another embodiment, no symbol repetition is provided and variable length Walsh sequences are used to handle data rate variations.
