Title: SPATIAL SHARING PROCEDURES IN WLAN SYSTEMS
Abstract:
A method and apparatus for receiving a NAV setting message is disclosed. The NAV setting message may include at least a group ID, a duration field and a TRN field. Based on the group ID of the NAV setting message, a determination may be made as to whether or not NAV setting message is a message of a same BSS of a STA. This determination may provide an indication as to whether or not an associated AP is busy for the duration indicated by the NAV setting message. When an associated AP is busy, a STA may determine to not transmit. When an associated AP is available, a STA may transmit accordingly. An AP may also make a determination to transmit available data based on any NAV setting messages received. This determination may be based on a group ID, a TRN field or a combination of the two.
