Abstract: This disclosure relates to techniques for synchronization signals. The synchronization signal comprise a primary synchronization signal (PSS) generated based on a PSS sequence and a secondary synchronization signal (SSS) generated based on an SSS sequence. The SSS sequence may be generated based on a first sequence corresponding to a first cyclic shift and a second sequence corresponding to a second cyclic shift. The first cyclic shift and the second cyclic shift are associated with Cell ID. The PSS sequence may be generated based on one of the first and the second sequences.

Abstract: Methods (700, 900) and nodes (110, 120) for transmission of broadcast information, over at least one antenna port, in a subframe, which transmission is received by a receiver (110) in a wireless communication system (100). The broadcast information is transmitted over a set of antenna ports comprising at least one antenna port, in at least one subframe (300) comprising a set of time-frequency resources, wherein a cell-specific reference signal, CRS, is not transmitted in each subframe (300). The method (700) comprises defining (701) a set of antenna ports for the set of time-frequency resources. Also, the method (700) comprises transmitting (702) the broadcast information on the defined (701) set of antenna ports, thereby using said set of time-frequency resources exclusively, such that they are unused for any other antenna port.

Abstract: Embodiments provide methods and devices for data transmission and assignment of uplink control channel resources in an uplink FDD carrier, for enabling a recipient to provide HARQ feedback for data transmitted in the downlink using carrier aggregation of a downlink FDD carrier and at least one TDD carrier. A method includes associating each downlink subframe in the downlink FDD carrier with an uplink control channel subframe in the uplink FDD carrier, associating each downlink subframe and special subframe in the TDD carrier with an uplink control channel subframe in the uplink FDD carrier, assigning uplink control channel resources in the uplink FDD carrier to the recipient, according to the made associations, and transmitting data on said downlink FDD carrier and/or TDD carrier, to be received by the recipient.

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.
