Claim 11:
12. A network node device for wireless communication, comprising a transceiver and a processor, wherein:
the transceiver is configured to:
transmit frequency resource information to indicate a set of frequency resources for physical random access channel (PRACH) preamble transmission, the transmitted frequency resource information being configured:
to indicate each frequency resource comprising at: an interlace information indicating at least one of an interlace of a block-interlaced frequency-division multiplexing (B-IFDM) allocation, a resource element allocation information indicating a subset of resource elements within each block of the at least one B-IFDM interlace, and a resource element spacing information,
such that an at least one resource element within at least one block of the at least one B-IFDM interlace is allocated for the transmission of one PRACH preamble according to a tone-interlaced frequency-division multiplexing (T-IFDM) allocation and the resource element allocation is repeated in each block of the at least one B-IFDM interlace, wherein a distribution of the subset of resource elements within each block of the at least one B-IFDM interlace is non-uniform; and
receive a signal comprising at least one PRACH preamble, each of the at least one PRACH preambles transmitted on one frequency resource of the indicated set of frequency resources, and the processor is configured to derive at least one index from the received signal, each derived index corresponding to one of the PRACH preambles contained in the received signal.
