Resource indication processing method, processing apparatus, access point, and station
A resource indication processing method is disclosed, and is applied to a wireless local area network that uses an OFDMA technology. The method includes: sending or receiving a trigger frame, where the trigger frame includes information (I 1 ) used to indicate whether the trigger frame allows random access transmission.
1. A Wireless Local Area Network (WLAN) transmitting method,
the method comprising:
sending, by an access point (AP), a trigger frame which includes a common information part and one or more user information parts located after the common information part,
wherein the common information part comprises sub-channel allocation information for indicating one or more sub-channels,
wherein at least one of the one or more user information parts comprises a user identifier (AID), a start location indication field and a number indication field,
wherein the AID is a value indicating that one or more contiguous resource units (RUs) allocated based on the at least one of the one or more user information parts are used for random access, the start location indication field is used to indicate a start location of the one or more contiguous RUs used for random access, and the number indication field is used to indicate a number of the one or more contiguous RUs used for random access, and
wherein the sub-channel allocation information further indicates a quantity of RUs, of the one or more contiguous RUs, associated with each sub-channel indicated by the sub-channel allocation information.
2. The method of claim 1 , wherein the value of the AID comprises: 0.
3. The method of claim 1 , wherein the sub-channel allocation information indicates the one or more sub-channels by dividing a whole channel into the one or more sub-channels.
4. The method of claim 1 , wherein the sub-channel allocation information comprises a bitwise mapping specifying the quantity of RUs for each sub-channel.
5. A Wireless Local Area Network (WLAN) receiving method,
the method comprising:
receiving, by a station, a trigger frame which includes a common information part and one or more user information parts located after the common information part,
wherein the common information part comprises sub-channel allocation information for indicating one or more sub-channels,
wherein at least one of the one or more user information parts comprises a user identifier (AID), a start location indication field and a number indication field,
wherein the AID is a value indicating that one or more contiguous resource units (RUs) allocated based on the at least one of the one or more user information parts is used for random access, the start location indication field is used to indicate a start location of the one or more contiguous RUs used for random access, and the number indication field is used to indicate a number of the one or more contiguous RUs used for random access, and
wherein the sub-channel allocation information further indicates a quantity of RUs, of the one or more contiguous RUs, associated with each sub-channel indicated by the sub-channel allocation information.
6. The method of claim 5 , wherein the value of the AID comprises: 0.
7. An apparatus of a Wireless Local Area Network (WLAN) comprising:
a processor; and
a memory communicatively coupled with the processor and storing instructions that when executed by the processor, configure the processor for:
sending a trigger frame, which includes a common information part and one or more user information parts located after the common information part,
wherein the common information part comprises sub-channel allocation information for indicating one or more sub-channels,
wherein at least one of the one or more user information parts comprises a user identifier (AID), a start location indication field and a number indication field,
wherein the AID is a value indicating that one or more contiguous resource units (RUs) allocated based on the at least one of the one or more user information parts are used for random access, the start location indication field is used to indicate a start location of the one or more contiguous RUs used for random access, and the number indication field is used to indicate a number of the one or more contiguous RUs used for random access, and
wherein the sub-channel allocation information further indicates a quantity of RUs, of the one or more contiguous RUs, associated with each sub-channel indicated by the sub-channel allocation information.
8. The apparatus of claim 7 , wherein the value of the AID comprises: 0.
9. An apparatus of a Wireless Local Area Network (WLAN) comprising:
a processor; and
a memory communicatively coupled with the processor and storing instructions that when executed by the processor, configure the processor for:
receiving a trigger frame, which includes a common information part and one or more user information parts located after the common information part,
wherein the common information part comprises sub-channel allocation information for indicating one or more sub-channels,
wherein at least one of the one or more user information parts comprises a user identifier (AID), a start location indication field and a number indication field,
wherein the AID is a value indicating that one or more contiguous resource units (RUs) allocated based on the at least one of the one or more user information parts is used for random access, the start location indication field is used to indicate a start location of the one or more contiguous RUs used for random access, and the number indication field is used to indicate a number of the one or more contiguous RUs used for random access, and
wherein the sub-channel allocation information further indicates a quantity of RUs, of the one or more contiguous RUs, associated with each sub-channel indicated by the sub-channel allocation information.
10. The apparatus of claim 9 , wherein the value of the AID comprises: 0.
