STR capability indication method and related device

[0123] The STR capability indication method provided in the embodiment of the present application can perform two-way interference parameter or STR capability indication for a link pair in the case of asymmetric interference between links.

[0124] Understandably, inter-link interference asymmetry refers to the interference caused by transmission on one link to reception on another link, and the interference caused by transmission on another link to reception on this link ,different. For example, in some cases, sending a PPDU on one link (such as link 1) interferes with receiving a PPDU on another link (such as link 2), but receiving a PPDU on another link (such as link 2) Sending PPDUs may not interfere with receiving PPDUs on one link (eg link 1). Interlink interference asymmetry is usually related to factors such as bandwidth and transmit power on the two links. see Figure 5 , Figure 5 It is a schematic diagram of spectrum templates of different bandwidths provided by th

[0161] The STR capability indication method provided in the embodiment of the present application can combine different bandwidth combinations on two links to determine STR capability information, and determine whether to support simultaneous sending and receiving operations through the STR capability information.

[0162] Understandably, as mentioned above, there are many factors that affect the ability of STR. Embodiment 2 of the present application mainly introduces the STR capability indication method provided by the embodiment of the present application in combination with bandwidth. see Figure 7 , Figure 7 It is a schematic diagram of the frequency interval between two links provided by the embodiment of the present application. Such as Figure 7 As shown, it is assumed that the frequency interval between two links is in the non-STR state from 0 to Δf1, and is in the STR state from Δf2 to infinity. When the frequency interval between the two links is very small, such

[0243] The embodiment of the present application provides a STR capability indication method, which can combine the interference parameters corresponding to different bandwidth combinations on the two links to determine whether the two links (in different bandwidth combinations) support simultaneous sending and receiving operations, and pass the STR capability The indication information indicates whether simultaneous transceiving operations are supported on the two links (in different bandwidth combinations).

[0244] Embodiment 3 of the present application is aimed at the same scenario as the aforementioned Embodiment 2, and both discuss the above-mentioned Figure 7 In the transition frequency interval between Δf1 and Δf2, whether the two links support simultaneous sending and receiving operations. The difference is that in the aforementioned embodiment 2, by indicating the interference parameter, the opposite end determines whether to support simultaneous sending and receiving
