Abstract

Embodiments of the present invention relate to a terminal scheduling method, a station, and a terminal. The method includes: sending, by a first station, a first notification message to a first terminal that is also in a first service set, where the first notification message is used to instruct the first terminal to send a sounding signal; receiving, by the first station, mutual interference information sent by a second terminal, where the mutual interference information includes a signal parameter value used to represent that signal interference is generated between the second terminal and the first terminal and identifier information used to determine the first terminal that sends the sounding signal, and the mutual interference information is sent if the second terminal obtains the sounding signal by means of listening; and performing, by the first station, scheduling processing on the first terminal and the second terminal according to the signal parameter value and the identifier information.

First claim

What is claimed is:

1. A terminal scheduling method, wherein the method comprises:
sending, by a first station, a first notification message to a first terminal that is also in a first service set, wherein the first notification message is used to instruct the first terminal to send a sounding signal;
receiving, by the first station, mutual interference information sent by a second terminal, wherein the mutual interference information comprises a signal parameter value used to represent that signal interference is generated between the second terminal and the first terminal and identifier information used to determine the first terminal that sends the sounding signal, and the mutual interference information is sent if the second terminal obtains the sounding signal by means of listening; and
performing, by the first station, scheduling processing on the first terminal and the second terminal according to the signal parameter value and the identifier information.

2. The terminal scheduling method according to claim 1 , wherein the first notification message comprises identifier information of an in-band/out-of-band time-frequency resource block used to send the sounding signal, so that the first terminal sends the sounding signal on the in-band/out-of-band time-frequency resource block.

3. The terminal scheduling method according to claim 2 , wherein the second terminal is specifically a terminal in the first service set; or
the second terminal is specifically a terminal in a second service set, wherein the second service set is a service set neighboring to the first service set; and
after the sending, by a first station, a first notification message to a first terminal that is also in a first service set, the method further comprises:
if the second terminal is in the first service set, sending, by the first station, a listening message to the specified second terminal, wherein the listening message is used to instruct the second terminal to listen to the sounding signal; or
if the second terminal is in the second service set, sending, by the first station, a second notification message to a second station in the second service set, wherein the second notification message is used by the second station to send a listening message to the specified second terminal, and the listening message is used to instruct the second terminal to listen to the sounding signal.

4. The terminal scheduling method according to claim 3 , wherein if the first terminal sends the sounding signal on the out-of-band time-frequency resource block, the sounding signal comprises identifier information of a communications module in the first terminal; and
the receiving, by the first station, mutual interference information sent by a second terminal, wherein the mutual interference information comprises a signal parameter value used to represent that signal interference is generated between the second terminal and the first terminal and identifier information used to determine the first terminal that sends the sounding signal specifically comprises:
if the first terminal sends the sounding signal on the in-band time-frequency resource block, and the second terminal is in the first service set and obtains the sounding signal by means of listening, receiving, by the first station, the mutual interference information sent by the second terminal, wherein the mutual interference information comprises the signal parameter value and the identifier information of the in-band time-frequency resource block; or
if the first terminal sends the sounding signal on the out-of-band time-frequency resource block, and the second terminal is in the first service set and obtains the sounding signal by means of listening, receiving, by the first station, the mutual interference information sent by the second terminal, wherein the mutual interference information comprises the signal parameter value and the identifier information of the communications module; or
if the first terminal sends the sounding signal on the in-band/out-of-band time-frequency resource block, and the second terminal is in the second service set and obtains the sounding signal by means of listening, receiving, by the first station, the mutual interference information that is sent by the second terminal by using the second station, wherein the mutual interference information comprises the signal parameter value and the identifier information of the in-band time-frequency resource block/the identifier information of the communications module.

5. The terminal scheduling method according to claim 4 , wherein the performing, by the first station, scheduling processing on the first terminal and the second terminal according to the signal parameter value and the identifier information specifically comprises:
updating, by the first station, a terminal mutual interference list according to the signal parameter value and the identifier information of the in-band time-frequency resource block/the identifier information of the communications module; and
performing, by the first station, scheduling processing on the first terminal and the second terminal by using the terminal mutual interference list.

6. The terminal scheduling method according to claim 5 , wherein the performing, by the first station, scheduling processing on the first terminal and the second terminal by using the terminal mutual interference list specifically comprises:
if the second terminal is in the first service set, scheduling, by the first station, either terminal of the first terminal and the second terminal to send an uplink/downlink signal on a first time-frequency resource block;
if the first terminal sends the uplink/downlink signal on the first time-frequency resource block, obtaining, by the first station from the terminal mutual interference list, identifier information of the second terminal whose signal parameter value does not exceed an interference threshold; and
sending, by the first station, a first scheduling message to the second terminal according to the identifier information of the second terminal, wherein the first scheduling message is used to instruct the second terminal to send a downlink/uplink signal on the first time-frequency resource block; or
if the second terminal sends the uplink/downlink signal on the first time-frequency resource block, obtaining, by the first station from the terminal mutual interference list, identifier information of the first terminal whose signal parameter value does not exceed an interference threshold; and
sending, by the first station, a first scheduling message to the first terminal according to the identifier information of the first terminal, wherein the first scheduling message is used to instruct the first terminal to send a downlink/uplink signal on the first time-frequency resource block.

7. The terminal scheduling method according to claim 5 , wherein the performing, by the first station, scheduling processing on the first terminal and the second terminal by using the terminal mutual interference list specifically comprises:
if the second terminal is in the first service set, scheduling, by the first station, either terminal of the first terminal and the second terminal to send an uplink/downlink signal on a first time-frequency resource block;
if the first terminal sends the uplink/downlink signal on the first time-frequency resource block, obtaining, by the first station from the terminal mutual interference list, identifier information of the second terminal whose signal parameter value exceeds the interference threshold; and
sending, by the first station, a second scheduling message to the second terminal according to the identifier information of the second terminal, wherein the second scheduling message comprises id
