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.
摘要翻译：公开了降低信道分配控制开销的STA，AP和方法。 STA接收具有HE SIG-A字段和HE SIG-B字段的高效率物理层汇聚协议数据单元（HE PPDU）。 SIG-B字段具有用户特定子字段（USS），每个子字段具有用于相关联的STA的流分配值（SAV），并且与指示USS之间的位置的唯一流索引号（SIN）相关联。 SINS随着SIG-B领域的增长而增加。在每个USS中分配的信道数量被限制为保持不变或单调随着SIN增加而变化。 STA从SAV，SIN和USS的数量确定信道分配。频道可以非连续地分配。大多数USS中的SAV可以指示从最终或初始信道开始的增加或减少信道和最终USS中的至少一个信道的分配。
