Classification: CPC H | IPC H

Claim 0:
1. A client device for wireless communication, the client device comprising: a transceiver, and a processor, wherein:
the transceiver is configured to receive 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;

the processor is configured to select a frequency resource of the set of frequency resources based at least partially on the received frequency resource information, and to generate a PRACH preamble to be transmitted on the selected frequency resource; and
the transceiver is further configured to transmit the generated PRACH preamble on the selected frequency resource.
