Abstract

A resource indication method in a wireless local area network is provided, where the method includes generating, by an access point, a data frame that includes a preamble, where the preamble includes a signaling indication part B (SIG-B), the SIG-B includes a common part and a user part following the common part. The common part is used to indicate a quantity of scheduled stations, identification information of the scheduled station, and a location of communication resource information of the scheduled station in the user part, the user part is used to indicate the communication resource information of the scheduled station, and the communication resource information includes resource indication information, MCS information of a data part, spatial flow quantity information, or power control information; and sending the data frame.

Claims

1. A method comprising:

generating, by an access point in a wireless local area network, a data frame that comprises a preamble, wherein the preamble comprises a signaling indication part B (SIG-B), wherein the SIG-B comprises a common part and a user part following the common part, wherein the common part indicates information for determining an end location or an end time of the common part, identification information of a scheduled station, and a location of communication resource information of the scheduled station in the user part, wherein the user part indicates the communication resource information of the scheduled station, and wherein the communication resource information comprises resource indication information, modulation and coding scheme (MCS) information of a data part, spatial flow quantity information, or power control information; and

sending, by the access point, the data frame.

2. The method according to claim 1,

wherein the identification information of the scheduled station in the common part comprises identification information of the scheduled station arranged in order, and

wherein an order of the communication resource information of the scheduled station in the user part is the same as an order of the identification information of the scheduled station indicated in the common part, to determine a location of the communication resource information of the scheduled station in the user part according to the order of the identification information of the scheduled station.

3. The method according to claim 2, wherein the identification information of the scheduled station comprises identification information of the scheduled station arranged at random, identification information of the scheduled station arranged in ascending order of identifier sizes of the scheduled station, or identification information of the scheduled station arranged in descending order of identifier sizes of the scheduled station.

4. The method according to claim 1,

wherein the common part comprises a first part with a fixed length and a second part with a non-fixed length that follows the first part,

wherein the first part indicates the information for determining the end location or the end time of the common part, and wherein the first part comprises a quantity of scheduled stations, an orthogonal frequency division multiple access (OFDMA) symbol quantity of the common part or the second part or an OFDMA symbol end time of the common part or the second part, and

wherein the second part indicates an identification information list of the scheduled station.

5. An access point in a wireless local area network, the access point comprising:

a processor; and

a non-transitory computer readable storage medium storing a program for execution by the processor, the program including instructions to;

generate a data frame that comprises a preamble, wherein the preamble comprises a signaling indication part B (SIG-B), wherein the SIG-B comprises a common part and a user part following the common part, wherein the common part indicates information for determining an end location or an end time of the common part, identification information of a scheduled station, and a location of communication resource information of the scheduled station in the user part, wherein the user part indicates the communication resource information of the scheduled station, and wherein the communication resource information comprises resource indication information, modulation and coding scheme (MCS) information of a data part, spatial flow quantity information, or power control information; and

transmit the data frame.

6. The access point according to claim 5,

wherein the identification information of the scheduled station in the common part comprises identification information of the scheduled station that is arranged in order, and

wherein an order of the communication resource information of the scheduled station in the user part is the same as an order of the identification information that is of the scheduled station that is indicated in the common part, to determine a location of the communication resource information of the scheduled station in the user part according to the order of the identification information of the scheduled station.

7. The access point according to claim 5, wherein the identification information of the scheduled station comprises identification information of the scheduled station that is arranged at random, identification information of the scheduled station that is arranged in ascending order of identifier sizes of the scheduled station, or identification information of the scheduled station that is arranged in descending order of identifier sizes of the scheduled station.

8. The access point according to either of claim 5,

wherein the common part comprises a first part with a fixed length and a second part with a non-fixed length that follows the first part,

wherein the first part indicates the information for determining the end location or the end time of the common part, and wherein first part comprises a quantity of scheduled stations, an orthogonal frequency division multiple access (OFDMA) symbol quantity of the common part or the second part, or an OFDMA symbol end time of the common part or the second part, and

wherein the second part indicates an identification information list of the scheduled station.
