Abstract:
The present disclosure provides a response method and device for groupcast data transmission, and a computer storage medium. The method includes: a first node transmits at least one groupcast frame to at least one groupcast group including more than one second node; a second node receives the groupcast frame, where a groupcast address carried by the groupcast frame corresponds to a groupcast group where the second node is located; the first node transmits trigger information to second nodes corresponding to the groupcast group; the second node receives the trigger information; when being determined to be a second node for randomly contending for transmitting a groupcast response frame, the second node contends for transmitting the groupcast response frame on a random access resource block allocated by the trigger information; when being determined to be a second node for regularly transmitting the groupcast response frame, the second node transmits, according to the trigger information, the groupcast response frame on a specified fixed access resource block.
Abstract:
Provided is a channel access method. The method includes: after a radio frame is received, determining that the radio frame is an overlapping basic service set (OBSS) radio frame; determining that the OBSS radio frame is a radio frame of a specified type or determining whether the OBS S radio frame carries specific spatial multiplexing instruction information; updating a local network allocation vector according to duration information carried in the OBSS radio frame; and performing channel access according to the local network allocation vector. Provided are a channel access device and a storage medium.
