Claim 9:
10. A method, the method comprising:
receiving, by a transceiver in a client device for wireless communication, frequency resource information to indicate a set of frequency resources for a physical random access channel (PRACH) preamble transmission, the received frequency resource information being configured:
to indicate each frequency resource comprising: 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;

selecting, by a processor in the client device for wireless communication, a frequency resource of the set of frequency resources based at least partially on the received frequency resource information;
generating, by the processor in the client device for wireless communication, a PRACH preamble to be transmitted on the selected frequency resource; and
transmitting, by the transceiver in the client device for wireless communication, the generated PRACH preamble on the selected frequency resource.
