    摘要: A STA, AP and method of reducing channel allocation control overhead are disclosed. The STA receives a high-efficiency Physical Layer Convergence Protocol Data Unit (HE PPDU) having a HE SIG-A field followed by a HE SIG-B field. The SIG-B field has user-specific subfields (USS), each having a stream allocation value (SAV) for an associated STA and associated with a unique stream index number (SIN) indicating a position among the USSs. The SINs increase with increasing position from the SIG-B field. The number of channels allocated in each USS is constrained to stay the same or monotonically change with increasing SIN. The STA determines channel allocation from the SAV, SIN and number of USSs. The channels may be allocated non-contiguously. The SAVs in most USSs may indicate an allocation to increasing or decreasing channels and in the final USS to at least one channel starting from a final or initial channel.
