Abstract: Example methods and apparatus for communicating encoded data blocks in wireless communication systems are disclosed. In one example embodiment, a method for receiving an encoded data block includes receiving a data transmission including a subset of a plurality of bits of the encoded data block. The example method also includes receiving a first control signal indicating whether the received subset is a first received subset associated with the encoded data block or whether one or more subsets were previously received for the encoded data block. The example method also further includes receiving a second control signal, the second control signal having a first state and a second state.

Abstract: Introducing a set of limitations on where different payload sizes are allowed in a control channel element aggregation ‘tree’ is shown. Following these limitations, the network element (e.g. Node B) will have a large flexibility for scheduling users, while the terminal (e.g. User Equipment) will have an option for still keeping the number of blind decoding attempts at a quite low number.

Abstract: An apparatus, such as a base station which may be an evolved Node-B, includes a wireless transmitter configurable to conduct communications with a plurality of user equipment located in a cell; and a user equipment identification module configurable to define a number of bits (m) of a cell-specific user equipment identifier that is a sequence of n bits, where m?n and to inform the user equipment of the value of m in a downlink message. The number of bits (m) represents a mask value specifying how many bits of the cell-specific user equipment identifier are to be used in signaling exchanges, thereby conserving system bandwidth and reducing signaling load.

Abstract: The invention relates to an OFDM-transmitter, comprising means for transforming (400) data to be transmitted in frequency-to-time transformation to a basic waveform containing waveform components representing subbands of the spectrum of the signal. The transmitter comprises means for forming (402) at least one alternative waveform from components of the basic waveform, where at least one component in the alternative waveform is delayed in time, and means for selecting (414) a waveform for transmission from the group of waveforms, containing the basic waveform and the at least one alternative waveform. The invention also relates to a method for transmitting an OFDM signal, a method for processing an OFDM signal and an OFDM signal processing arrangement.

Abstract: A receiver includes, in series, at least one receive antenna, a buffer, and arithmetic logic block, a symbol detector, and a phase noise estimator. A further feedback loop couples an output of the phase noise estimator to an input of the arithmetic logic block for providing an estimate of phase noise. The buffer is for storing the received signal. The arithmetic logic block, such as a multiplier, is for removing the estimate of phase noise, received via the feedback loop, from the buffered signal. The symbol detector is for estimating a symbol from the output of the arithmetic logic block. The phase noise estimator estimates phase noise from two inputs received from the symbol detector: the estimated symbol and the remainder signal. Preferably, the phase noise estimator performs an IFFT on these two inputs and Kalman filters the result. Iteratively estimating the phase noise improves precision substantially.
