Channel access period allocation method, apparatus, and system

A channel access period allocation apparatus, wherein the apparatus is an access point (AP), and the apparatus comprises:

• a processor;
• and
• a non-transitory computer readable storage medium storing instructions that are executable by the processor, wherein the instructions are executed by the processor to:
• receive first information sent by a first station (STA), wherein the first information is used by the first STA to request a dynamic service period (DSP) from the AP;
• and
• send second information to the first STA, wherein the second information is used to instruct the first STA to send a data frame to the AP in a first DSP, wherein a start time of the first DSP falls within a first preset time period following an end time of a service period (SP) of the first STA, and the first DSP requested by the first STA is pre-allocated to a second STA having a priority that is lower than that of the first STA, wherein a time delay of the first STA for sending the data frame satisfies a time delay requirement of a quality of service QoS in the first preset time period, wherein the first DSP comprises a first sub-DSP and a second sub-DSP, and the first sub-DSP is before the second sub-DSP;
• send, by the AP, third information to the first STA at a start time of the first sub-DSP, wherein the third information is used by the AP to perform on the first STA at least one of:
• a coding control and a lens control;
• and
• wherein the send, by the AP, the second information to the first STA comprises:
• send, by the AP, the second information to the first STA in the first sub-DSP, wherein the second information is used to instruct the first STA to send the data frame to the AP in the second sub-DSP.
