Title: BLOCK-IFDMA MULTIPLEXING SCHEME WITH FLEXIBLE PAYLOAD
Abstract:
Various communication systems may benefit from multiplexing schemes. For example, various wireless communication systems may benefit from a block-IFDMA multiplexing scheme with a flexible payload. A method can include determining whether a first type of uplink signal or a second type of uplink signal is to be processed for transmission on an interlace. The method can also include determining whether to apply spreading based on intra-symbol spreading codes, inter-symbol spreading codes, or both intra-symbol spreading codes and inter-symbol spreading codes, based on the determination of whether the first type of uplink signal or the second type of uplink signal is to be processed for transmission. The method can further include causing transmission of the determined at least one of the first type of uplink signal and the second type of uplink signal according to the determination regarding applying spreading.
