摘要： This document discloses a solution for generating a reference symbol sequence for a radio transmitter. According to an aspect, a method comprises in a transmitter apparatus: generating a Zadoff-Chu sequence for a reference signal; performing a frequency-domain cyclic shift on the Zadoff-Chu sequence; extending the cyclically shifted sequence to a desired length; performing a time-domain cyclic shift on the sequence having the desired length, resulting in a reference symbol sequence; arranging the reference symbol sequence to at least some resource elements of a set of physical resource blocks, and causing transmission of the reference symbol sequence in the set of physical resource blocks.

摘要： Various communication systems may benefit from improved signaling. For example, communication systems may benefit from sending a multi-numerology reference signal that allows a receiving user equipment to perform simultaneous beamforming training, and channel estimation or channel state information acquisition. A method may include receiving at a user equipment a multi-numerology joint reference signal (610). The reference signal may include a reference signal for data channel demodulation or channel state information acquisition, and beamforming training. The method may also include performing simultaneous beamforming training and channel estimation or channel state information acquisition based on the multi-numerology joint reference signal (620).

摘要： Various communication systems may benefit from the appropriate monitoring of communication channels. For example, certain wireless communication systems may benefit from downlink control channel monitoring optimized for discontinuous reception mode and/or narrowband operation. A method can include selecting a search space configuration from a plurality of search space configurations for a user equipment. The method can also include operating the user equipment in the selected search space configuration.

摘要： A cellular communication system comprising a plurality of user equipment and a network infrastructure. Radio resource of the plurality of cells is divided into more than one radio resource groups. A network infrastructure element detects a requirement of radio resource allocation for a user equipment and determines effective interference to be generated by the required radio resource to a defined group of neighboring cells. User equipment is allocated a radio resource from one of the radio resource groups on the basis of the determined effective interference to be generated to the defined group of neighboring cells. Inter-cell interference decreases and the throughput of the cellular system increases, but the exchange of physical layer information is not increased.

摘要： According to an aspect, there is provided a waveform processing device. The waveform processing device includes circuitry for receiving an input signal including one or more subsequent orthogonal frequency division multiplexing, OFDM, symbol blocks each of which includes a cyclic prefix and an OFDM data block and corresponds to one or more subbands. Further, the waveform processing device includes circuitry for segmenting each OFDM symbol block of the input signal into a set of a pre-defined number of partially overlapping signal blocks of equal length so that non-overlapping samples of the pre-defined number of partially overlapping signal blocks in each set include, in combination, an OFDM data block. Moreover, the waveform processing device includes circuitry for filtering each signal block in each set and for combining the filtered signal blocks in each set using overlap-and-save processing to produce one or more filtered OFDM data blocks for each subband.
