Abstract: Methods and nodes for transmission of downlink control channel signals in a downlink frequency carrier of a wireless communication system, wherein at least two PRB pairs, configurable for the transmission of a downlink control channel have different numbers of time-frequency resource elements available for the transmission of said downlink control channel. The method comprises allocating at least one set S of PRB pairs; arranging time-frequency resource elements from said set S into an aggregation comprising at least one level; determining a set LS of aggregation levels supported for the transmission of a downlink control channel within the allocated set of PRB pairs, based on the number of time-frequency resource elements available for the transmission of a downlink control channel in PRB pairs of the set S; and transmitting the downlink control channel within said set S of PRB pairs.

Abstract: Methods and apparatus are provided for facilitating synchronization between a base station (BS) and a user equipment (UE) in a mobile communication system. The UE receives a synchronization signal originated by the BS. The synchronization signal is encoded with a selected cyclically permutable (CP) codeword. Encoding of the synchronization signal is facilitated by a repetitive cyclically permutable (RCP) codeword derivable from the selected CP codeword. The RCP codeword has a plurality of codeword elements each associated with a value, the value of at least one codeword element in the RCP codeword being repeated in another codeword element position in the RCP codeword. And the synchronization signal is decoded in accordance with repetitive structure of the RCP codeword.

Abstract: The invention relates to a client device (100) and a network access node (300) for transmitting and receiving a random access preamble. The modulation sequence for the random access preamble is based on a first sequence and a second sequence. The first sequence is a sequence from a set of near-orthogonal sequences and the second sequence is a sequence from a set of constant envelope sequences. Due to its construction, the random access preamble herein provides low PAPR and suppresses the side-lobes in its auto-correlation function while producing a set of preambles with low cross-correlation. Furthermore, the invention also relates to corresponding methods and a computer program.

Abstract: The disclosure relates to a network node and a user device. The network node is configured to determine a resource indicator comprising a single resource allocation value that specifies a first start index and a first number of frequency resources. The first start index and the first number of frequency resources are used for allocating a first set of contiguous frequency resources within a first sub-band, and a corresponding first set of contiguous frequency resources within a second sub-band. The first sub-band and the second sub-band are non-overlapping and comprise equal number of frequency resources. The network node includes a transceiver configured to transmit a transmission grant comprising the resource indicator to the user device.
