Abstract
An extreme-high-throughput (EHT) physical-layer protocol data unit (PPDU) is signaled between a first station (STA) and a second STA to indicate a resource unit (RU) allocation with respect to multiple users. One or more RU allocated to the first STA or the second STA as indicated in the EHT PPDU can be determined by using a RU allocation table that includes, in addition to entries corresponding to RUs allocatable to a plurality of users, one or more empty RU entries corresponding to one or more of an empty 242-tone RU, an empty 484-tone RU and an empty 996-tone RU.
Claims20
A method, comprising:
- signaling between a first station (STA) and a second STA an extreme-high-throughput (EHT) physical-layer protocol data unit (PPDU) indicating a resource unit (RU) allocation with respect to multiple users;
- and
- determining one or more RU allocated to the first STA or the second STA as indicated in the EHT PPDU by using a RU allocation table comprising, in addition to entries corresponding to RUs allocatable to a plurality of users, one or more empty RU entries corresponding to one or more of an empty 242-tone RU, an empty 484-tone RU and an empty 996-tone RU.
An apparatus, comprising:
- a transceiver configured to communicate wirelessly;
- and
- a processor coupled to the transceiver and configured to perform operations comprising:
- signaling, via the transceiver, between a first station (STA) and a second STA an extreme-high-throughput (EHT) physical-layer protocol data unit (PPDU) indicating a resource unit (RU) allocation with respect to a plurality of users;
- and
- determining one or more RU allocated to the first STA or the second STA as indicated in the EHT PPDU,
- wherein a number of one or more user fields in the EHT PPDU is less than a number of a plurality of RU allocation subfields in the EHT PPDU in an event that at least one of the plurality of RU allocation subfields corresponds to an empty RU not assigned to any user.
