Abstract
This application provides a data communications method and apparatus. The method includes: A first station (STA) receives time adjustment information, where the time adjustment information is used to indicate a sending moment at which a signal is sent by using each of at least two beams. The first STA may send data at a corresponding sending moment based on the time adjustment information using a corresponding beam. In this way, an access point (AP) can simultaneously receive data sent by one station using at least two beams. This ensures data validity and improves data communication efficiency.
Claims9
A data communications method, comprising:
- receiving from an access point, by a first station, time adjustment information indicating a sending time point at which a signal is to be sent using each of at least two beams, the at least two beams corresponding to at least one station, and the first station is one of the at least one station, wherein the time adjustment information comprises a time offset of the sending time point at which the signal is sent using a first beam in the at least two beams relative to a preset time point, and a time offset of the sending time point of each beam in the least two beams, other than the first beam, relative to the sending time point of the first beam;
- and
- sending to the access point, by the first station based on the time adjustment information, data using a beam that belongs to the first station and that is in the at least two beams.
A data communications method, comprising:
- sending, by an access point, time adjustment information to at least one station, wherein the time adjustment information indicates a sending time point at which a signal is scheduled to be sent using each of at least two beams corresponding to a first station of the at least one station, wherein the time adjustment information comprises a time offset of the sending time point at which the signal is sent using a first beam in the at least two beams relative to a preset time point, and a time offset of the sending time point of each beam in the least two beams, other than the first beam, relative to the sending time point of the first beam;
- and
- receiving, by the access point, data sent by the first station based on the time adjustment information using the at least two beams.
A data communications apparatus on a first station side, comprising:
- a transceiver;
- a memory comprising computer-executable instructions;
- and
- one or more processors in communication with the transceiver and the memory, wherein the instructions, when executed by the one or more processors, carry out a method comprising:
- receiving from an access point, time adjustment information indicating a sending time point at which a signal is to be sent using each of at least two beams, the at least two beams corresponding to at least one station, and the first station is one of the at least one station, wherein the time adjustment information comprises a time offset of the sending time point at which the signal is sent using a first beam in the at least two beams relative to a preset time point, and a time offset of the sending time point of each beam in the least two beams, other than the first beam, relative to the sending time point of the first beam;
- and
- processing, based on the time adjustment information, to control the transceiver to send data using a beam that belongs to the first station and that is in the at least two beams.
