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: A client device for wireless communication has a transceiver, and a processor. The transceiver receives frequency resource information to indicate a set of frequency resources for a PRACH preamble transmission. The frequency resource information indicates each frequency resource having: interlace information of B-IFDM allocation, resource element allocation information indicating a subset of resource elements within each block of the B-IFDM interlace, and resource element spacing information, such that a resource element within a block of the B-IFDM interlace is allocated for the transmission of one PRACH preamble according to a T-IFDM allocation. The resource element allocation is repeated in each block of the B-IFDM interlace. The processor is configured to select a frequency resource based on the received frequency resource information, and generate a PRACH preamble to be transmitted on the selected frequency resource. The transceiver transmits the generated PRACH preamble on the selected frequency resource.
