Transmission method and apparatus for wireless network, communication node and storage medium

1. A transmission method for a wireless network, applied to a first communication node and comprising:

receiving a physical-layer protocol data unit (PPDU) which carries first identifier information;

determining whether to classify the PPDU as a PPDU outside a basic service set, BSS, or as a PPDU inside the BSS;

in response to classifying the PPDU as a PPDU outside the BSS, keeping a locally stored network allocation vector (NAV) unchanged; and

in response to classifying the PPDU as a PPDU inside the BSS, updating the locally stored NAV and ignoring the updated NAV in a process of multi-access point transmission;

wherein the determining whether to classify the PPDU as a PPDU outside a basic service set, BSS, or as a PPDU inside the BSS comprises:

in response to at least one access point establishing a multi-access point transmission group and the first communication node belonging to the multi-access point transmission group, determining to classify the PPDU as a PPDU inside the BSS; or

in response to at least one access point making a multi-access point transmission agreement and the first communication node participating in the multi-access point transmission agreement, determining to classify the PPDU as a PPDU inside the BSS.

2. The method of claim 1 , wherein:

the first identifier information is used to trigger a multi-access point transmission operation; and

the method further comprises:

performing the multi-access point transmission operation according to the first identifier information.

3. The method of claim 1 , further comprising:

in response to the PPDU further comprising second identifier information, determining whether to participate in the multi-access point transmission according to the second identifier information;

in response to determining to participate in the multi-access point transmission, updating the locally stored NAV and ignoring the updated NAV in the process of multi-access point transmission; and

in response to determining not to participate in the multi-access point transmission, keeping the locally stored NAV unchanged.

4. The method of claim 1 , wherein:

the first identifier information is indicated by a first setting field in a Media Access Control (MAC) header in a radio frame in the PPDU, or indicated by a second setting field in a physical-layer signaling field in the PPDU; and

in response to the PPDU further comprising second identifier information, the second identifier information is indicated by a third setting field in the MAC header in the radio frame in the PPDU, or indicated by a fourth setting field in the physical-layer signaling field in the PPDU.

5. The method of claim 1 , wherein the locally stored NAV is a NAV for multi-access point transmission.

6. A transmission method for a wireless network which is applied to a second communication node, comprising:

generating a physical-layer protocol data unit (PPDU) which carries first identifier information; and

sending the PPDU to a first communication node to cause the first communication node to:

determine whether to classify the PPDU as a PPDU outside a basic service set, BSS, or as a PPDU inside the BSS;

keep a locally stored network allocation vector, NAV, unchanged, in response to classifying the PPDU as a PPDU outside the BSS; and

update the locally stored NAV and ignore the updated NAV in a process of multi-access point transmission, in response to classifying the PPDU as a PPDU inside the BSS;

wherein the first communication node determines to classify the PPDU as a PPDU inside the BSS, in response to at least one access point establishing a multi-access point transmission group and the first communication node belonging to the multi-access point transmission group; or the first communication node determines to classify the PPDU as a PPDU inside the BSS, in response to at least one access point making a multi-access point transmission agreement and the first communication node participating in the multi-access point transmission agreement.

7. The method of claim 6 , wherein the first identifier information is used to trigger at least one communication node to perform a multi-access point transmission operation.

8. The method of claim 6 , wherein the PPDU further comprises:

second identifier information used to indicate a receiver of a radio frame in the PPDU.

9. The method of claim 6 , wherein:

the first identifier information is indicated by a first setting field in a Media Access Control (MAC) header in a radio frame in the PPDU, or indicated by a second setting field in a physical-layer signaling field in the PPDU; and

in response to the PPDU further comprising second identifier information, the second identifier information is indicated by a third setting field in the MAC header in the radio frame in the PPDU, or indicated by a fourth setting field in the physical-layer signaling field in the PPDU.

10. A communication node, comprising:

at least one processor; and

a storage apparatus, configured to store at least one program;

wherein the at least one program, when executed by the at least one processor, causes the at least one processor to implement the transmission method for a wireless network of claim 1 .

11. A non-transitory computer-readable storage medium storing a computer program, wherein the computer program, when executed by a processor, causes the processor to implement the transmission method for a wireless network of claim 1 .

12. A communication node, comprising:

at least one processor; and

a storage apparatus, configured to store at least one program;

wherein the at least one program, when executed by the at least one processor, causes the at least one processor to implement the transmission method for a wireless network of claim 6 .

13. A non-transitory computer-readable storage medium storing a computer program, wherein the computer program, when executed by a processor, causes the processor to implement the transmission method for a wireless network of claim 6 .
