Patent ID: 11950214

Abstract:
A client device for wireless communication includes a transceiver and a processor. 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 frequency resource information includes at least one of: 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. The resource element allocation is repeated in each block of the at least one B-IFDM interlace.
