Data parsing to support resource unit aggregation
This disclosure provides methods, devices and systems for data parsing for resource unit (RU) aggregation. A wireless communication device (such as an access point (AP) or a station (STA)) may allocate a set of RUs for a receiving device in a basic service set (BSS). The set of RUs may be associated with multiple bandwidth segments of a bandwidth allocation and may be non-contiguous or contiguous. The wireless communication device may determine a data parsing and encoding scheme for a set of information bits. The data parsing may be implemented at a medium access control (MAC) layer or physical (PHY) layer and the encoding may correspond to a joint encoding or a separate encoding for each RU of the allocation. The wireless communication device may then distribute the coded bits to the set of RUs for transmission.
