Abstract
A training packet sending method and apparatus, where the method includes generating, by a first device, a training packet, where the training packet includes a preamble, a header, and a training field, and the header includes at least a legacy header, and repeatedly sending, by the first device, the preamble using N channels, sending the legacy header in the header using the N channels, and sending the training field to at least one second device using H channels of the N channels, where N is greater than 1, and H is greater than 1 and less than or equal to N.
Claims20
A data packet sending method, comprising:
- generating, by a first device, a training packet, wherein the training packet comprises a preamble, a header, and a training field, and wherein the header comprises a legacy header;
- and
- repeatedly sending, by the first device, the preamble using N channels;
- sending, by the first device, the legacy header in the header using the N channels;
- and
- sending, by the first device, the training field to at least one second device using H channels of the N channels, wherein the N is greater than one, and wherein the H is greater than one and less than or equal to the N.
A training packet receiving method, comprising:
- receiving, by a second device on L channels of N channels, a training field from a first device using a training packet, wherein the training packet comprises a preamble, a header comprising a legacy header, and the training field, wherein the preamble is repeatedly received from the first device using the N channels, wherein the legacy header in the header is received from the first device using the N channels, wherein the training field is received from the first device using H channels of the N channels, wherein the N is greater than one, wherein the H is greater than one and less than or equal to the N, and wherein the L is less than or equal to the H;
- measuring, by the second device, the L channels based on the received training field;
- determining, by the second device measurement results of the L channels;
- and
- transmitting, by the second device, the measurement results of the L channels to the first device.
A training packet sending apparatus, comprising:
- a processor configured to generate a training packet, wherein the training packet comprises a preamble, a header, and a training field, and wherein, the header comprises a legacy header;
- and
- a transceiver coupled to processor and configured to:
- repeatedly send the preamble using N channels;
- send the legacy header in the header using the N channels;
- and
- send the training field to at least one second device using H channels of the N channels, wherein the N is greater than one, and wherein the H is greater than one and less than or equal to the N.
A data packet receiving apparatus, comprising:
- a transceiver configured to receive, on L channels of N channels, a training field from a first device using a training packet, wherein the training packet comprises a preamble, a header comprising a legacy header, and the training field, wherein:
- the preamble is repeatedly received from the first device using the N channels, wherein the legacy header in the header is received from the first device using the N channels, wherein the training field is received from the first device using H channels of the N channels, wherein the N is greater than one, wherein the H is greater than one and less than or equal to the N, and wherein the L is less than or equal to the H;
- and
- a processor coupled to the transceiver and configured to:
- measure the L channels based on the received training field;
- determine measurement results of the L channels;
- and
- transmit the measurement results of the L channels to the first device.
