Information transmission method, network device, and user equipment

A second user equipment, comprising:

• a processor;
• and
• a storage medium storing instructions that, when executed by the processor, cause the second user equipment to:
• receive a broadcast frame from a network apparatus, wherein the broadcast frame comprises first duration information and second duration information, wherein the first duration information is configured to indicate a first time range of association beamforming training (A-BFT) for a first user equipment corresponding to the 802.11ad standard, wherein the second duration information is configured to indicate a second time range of A-BFT for the second user equipment corresponding to the 802.11ay standard, and wherein a duration of the second time range is equal to or greater than a duration of the first time range;
• determine the second time range and randomly select a second timeslot from the second time range;
• and
• send a second-type frame to the network apparatus in the second timeslot, wherein a transmission duration of a first-type frame transmitted in a first timeslot randomly selected from the first time range is equal to or greater than a transmission duration of the second-type frame;
• wherein the first duration information is located in an A-BFT length field of a beacon interval (BI) control field in the broadcast frame, and the second duration information is located in at least one bit in the BI control field other than the A-BFT length field.

A non-transitory computer-readable storage medium storing instructions that, when executed, cause a network apparatus to:

• send a broadcast frame, wherein the broadcast frame comprises first duration information and second duration information, wherein the first duration information is configured to indicate a first time range of association beamforming training (A-BFT) for a first user apparatus corresponding to the 802.11ad standard, wherein the second duration information is configured to indicate a second time range of A-BFT for a second user apparatus corresponding to the 802.11ay standard, and wherein a duration of the second time range is equal to or greater than a duration of the first time range;
• receive a first-type frame from the first user apparatus in a first timeslot randomly selected from the first time range;
• and
• receive a second-type frame from the second user apparatus in a second timeslot randomly selected from the second time range, wherein a transmission duration of the first-type frame is equal to or greater than a transmission duration of the second-type frame;
• wherein the first duration information is located in an A-BFT length field of a beacon interval (BI) control field in the broadcast frame, and the second duration information is located in at least one bit in the BI control field other than the A-BFT length field.
