Abstract
A method of communicating, by a first device, with at least one second device in a wireless local area network (WLAN) system includes allocating at least one resource unit (RU) within a bandwidth to a second device; generating at least one subfield defining the at least one RU; generating a trigger frame comprising a user information field comprising the at least one subfield, and transmitting a PPDU including the trigger frame to the at least one second device, wherein the generating comprises setting at least seven bits associated with the at least one RU and setting at least two bits as a value defining a subband that includes the at least one RU when the band width comprises at least four subbands.
Claims12
A method of communicating, by a first device, with at least one second device in a wireless local area network (WLAN) system, the method comprising:
- allocating a multi-resource unit (RU) within a bandwidth to the at least one second device, the multi-RU including at least two single RUs;
- generating at least one subfield defining the multi-RU;
- and
- transmitting a physical layer protocol data unit (PPDU) including the at least one subfield to the at least one second device,
- wherein the generating the at least one subfield comprises:
- generating at least seven bits in a first subfield based on a size of the multi-RU and an index of the multi-RU;
- and
- generating at least one first bit in the first subfield and at least one second bit in a second subfield based on a subband where the multi-RU is located within the bandwidth,
- wherein the first subfield is a RU allocation subfield, and the second subfield is a PS 160 subfield.
A method of communicating, by a second device, with a first device in a wireless local area network (WLAN) system, the method comprising:
- receiving a physical layer protocol data unit (PPDU) from the first device;
- extracting at least one subfield defining a multi-resource unit (RU) allocated to the second device within a bandwidth, the multi-RU including at least two single RUs;
- and
- identifying the multi-RU based on the at least one subfield,
- wherein the identifying the multi-RU comprises:
- identifying a size of the multi-RU based on at least seven bits in a first subfield included in the at least one subfield and
- identifying, based on at least one first bit in the first subfield and at least one second bit in a second subfield included in the at least one subfield, a subband where the multi-RU is located within the bandwidth,
- wherein the first subfield is an RU allocation subfield, and the second subfield is a PS 160 subfield.
