Apparatus and method for scheduling timeslot

A method for scheduling a timeslot, comprising:

• acquiring, by an apparatus, first interference information for determining whether a link of a first basic service set (BSS) experiences interference from a link of at least one second BSS;
• acquiring, by the apparatus, second interference information for determining whether the link of the at least one second BSS experiences interference from the link of the first BSS;
• acquiring, by the apparatus, timeslot scheduling information of the link of the at least one second BSS, wherein the timeslot scheduling information indicates information about a scheduled timeslot of the link of the at least one second BSS;
• and
• scheduling, by the apparatus, a timeslot for the link of the first BSS according to the first interference information, the second interference information, and the timeslot scheduling information, so that the link of the first BSS and the link of the at least one second BSS do not interfere with each other when communication is performed in a same timeslot;
• wherein before acquiring the first interference information, the method further comprises:
• receiving interference measurement indication information from a synchronization personal basis service set control point (PCP) or a synchronization access point (AP) within a cluster to which the first BSS and the at least one second BSS belong, wherein the interference measurement indication information indicates that a PCP or an AP of each of the first BSS and the at least one second BSS are to send channel quality measurement request information to a user station (STA) of the respective BSS, and wherein PCPs or APs of the first BSS and the at least one second BSS belong to a same cluster;
• wherein the interference measurement indication information is carried in a Media Access Control (MAC) element, and the MAC element comprises a cluster spatial sharing enable field that enables or disables a service period (SP) spatial sharing mechanism between the first BSS and the at least one second BSS.

An apparatus for scheduling a timeslot, comprising a processor and a memory, wherein the memory is configured to provide instructions for the processor, and wherein, based on the instructions, the processor is configured to perform the following steps:

• acquiring interference measurement indication information from a synchronization personal basis service set control point (PCP) or a synchronization access point (AP) within a cluster to which a first basic service set (BSS) and at least one second BSS belong, wherein the interference measurement indication information indicates that a PCP or an AP of each of the first BSS and the at least one second BSS is to send channel quality measurement request information to a user station (STA) of the respective BSS, and wherein PCPs or APs of the first BSS and the at least one second BSS belong to a same cluster;
• acquiring first interference information for determining whether a link of the first BSS experiences interference from a link of the at least one second BSS;
• acquiring first interference information for determining whether a link of the first BSS experiences interference from a link of the at least one second BSS;
• acquiring second interference information for determining whether the link of the at least one second BSS experiences interferences from the link of the first BSS;
• acquiring timeslot scheduling information of the link of the at least one second BSS, wherein the timeslot scheduling information indicates information about a scheduled timeslot of the link of the at least one second BSS;
• and
• scheduling a timeslot for the link of the first BSS according to the first interference information, the second interference information, and the timeslot scheduling information, so that the link of the first BSS and the link of the at least one second BSS do not interfere with each other when communication is performed in a same timeslot;
• wherein the interference measurement indication information is carried in a Media Access Control (MAC) element, and the MAC element comprises a cluster spatial sharing enable field that enables or disables a service period (SP) spatial sharing mechanism between the first BSS and the at least one second BSS.
