Abstract
Embodiments of this application provide an information transmission method, a network device, and a user equipment. The method provided in this application includes: sending, by a network device, a broadcast frame that includes first duration information and second duration information that are of A-BFT (Association Beamforming Training); receiving a frame sent by a first user equipment in a timeslot randomly selected from a first time range; and receiving a frame sent by a second user equipment in a timeslot randomly selected from a second time range. According to the embodiments of this application, beamforming training efficiency can be improved.
Claims20
An information transmission method, comprising:
- sending, by a network device, a broadcast frame, wherein the broadcast frame comprises first duration information and second duration information that are of association beamforming training A-BFT, wherein the first duration information to indicates a first time range for a first user equipment from which a timeslot is selected randomly by the first user equipment, and the second duration information indicates a second time range for a second user equipment from which a timeslot is selected randomly by the second user equipment;
- receiving, by the network device, a first-type frame from the first user equipment in the timeslot randomly selected from the first time range;
- and
- receiving, by the network device, a second-type frame from the second user equipment in the timeslot randomly selected from the second time range.
An information transmission method, comprising:
- receiving, by a second user equipment, a broadcast frame sent by a network device, wherein the broadcast frame comprises first duration information and second duration information that are of association beamforming training A-BFT, wherein the first duration information indicates a first time range for a first user equipment from which a timeslot is selected randomly by the first user equipment, and the second duration information indicates a second time range for the second user equipment from which a timeslot is selected randomly by the second user equipment;
- determining, by the second user equipment, a second time range according to the second duration information, and randomly selecting a timeslot from the second time range;
- and
- sending, by the second user equipment, a second-type frame to the network device in the timeslot randomly selected from the second time range.
A network device, comprising:
- a transmitter;
- and
- a receiver,
- wherein the transmitter is configured to send a broadcast frame, wherein the broadcast frame comprises first duration information and second duration information that are of association beamforming training A-BFT, wherein the first duration information indicates a first time range for a first user equipment from which a timeslot is selected randomly by the first user equipment, and the second duration information indicates a second time range for a second user equipment from which a timeslot is selected randomly by the second user equipment;
- and
- wherein the receiver is configured to:
- receive a first-type frame from the first user equipment in the timeslot randomly selected from the first time range;
- and
- receive a second-type frame from the second user equipment in the timeslot randomly selected from the second time range.
A second user equipment, comprising:
- a receiver;
- a transmitter;
- and
- a processor, wherein the processor is connected to the receiver and connected to the transmitter,
- wherein:
- the receiver is configured to receive a broadcast frame sent by a network device, wherein the broadcast frame comprises first duration information and second duration information that are of association beamforming training A-BFT, wherein the first duration information indicates a first time range for a first user equipment from which a timeslot is selected randomly by the first user equipment, and the second duration information indicates a second time range for the second user equipment from which a timeslot is selected randomly by the second user equipment;
- the processor is configured to:
- determine a second time range according to the second duration information, and randomly select a timeslot from the second time range;
- and
- the transmitter is configured to send a second-type frame to the network device in the timeslot randomly selected from the second time range.
