Abstract: Various communication systems may benefit from an improved signaling protocol. For example, machine type communications may benefit from improved scheduling signaling. A method includes receiving at a user equipment a signal comprising a radio configuration time trace from a base station. The radio configuration time trace parameter defines future, time-limited radio configuration options for a user equipment. The method also includes determining at the user equipment a radio access action based on access action based on the received radio configuration options. In addition, the method includes using the radio configuration options to carry out the determined radio access action.

Abstract: A method comprising: receiving first information at a user equipment, storing at least some of the received first information at the user equipment; in response to incorrect decoding of at least some of the received first information by the user equipment, receiving second information at the user equipment, the second information comprising a hybrid automatic repeat request (HARQ) re-transmission of at least some of the first information, and the second information further comprising a scheduling allocation, the scheduling allocation comprising scheduling information of the received first information; and using the scheduling allocation, by the user equipment, to perform soft-combining of the stored first information and the received re-transmission of at least some of the first information.

Abstract: Methods and apparatuses for Orthogonal Frequency Division Multiplexing (OFDM) based communication are disclosed. In a method at least some least important bits derived from data to be transmitted are mapped into at least one portion of an OFDM transmission unit, the at least one portion being reserved for the least important bits. More important bits derived from said data are mapped into a different portion of the ODFM transmission unit.

Abstract: Systems, methods, apparatuses, and computer program products for generating sequences for zero-tail discrete fourier transform (DFT)-spread-orthogonal frequency division multiplexing (OFDM) (ZT DFT-s-OFDM) reference signals. One method includes adding a zero vector to an input sequence, and performing an iterative manipulation of the input sequence. The performing of the iterative manipulation of the input sequence may include, for example: computing frequency domain response of the sequence, normalizing elements of the computed frequency domain sequence to unitary power while maintaining phase of each of the elements, converting the sequence to time domain, generating a zero-padded sequence by forcing a zero head and tail of the sequence, and repeating the steps until a final sequence with zero-tail and flat frequency response is obtained.

Abstract: An apparatus and method for performing an admission control of a terminal device with an antenna array in a cellular network is provided. The admission control decision is based on a direction-specific load determined by an estimation of a load-dependent directional parameter. Additionally, a cell-splitting function with at least two scrambling codes can be implemented.
