An system comprising: a transceiver (510, 520) adapted for use in a wireless personal area network, wherein said transceiver is configured for spatial reuse using a virtual time division multiple access, TDMA, technique based on a directional transmission to a receiving device, wherein the spatial reuse allows additional non-interfering spatially separate transceivers (530, 550) to perform concurrent transmissions without interfering with the directional transmission of said transceiver, wherein all links associated with said transceiver and said additional transceivers are divided into a number of spatial reuse groups based on a message flow wherein: under a centralized MAC a Coordinator is configured to announce on a control channel a time and a data channel to be used for the directional transmission of an existing link or under a distributed MAC, said transceivers are configured to announce their directional transmissions individually; upon receiving the announcement said additional transceivers (530, 540, 550) are configured to listen for a predetermined time to determine whether the additional transceivers can detect the directional transmission; and each of the additional transceivers are configured to report (440, 445) under a centralized MAC their compatibility with the link under consideration through said control channel. a transceiver (510, 520) adapted for use in a wireless personal area network, wherein said transceiver is configured for spatial reuse using a virtual time division multiple access, TDMA, technique based on a directional transmission to a receiving device, wherein the spatial reuse allows additional non-interfering spatially separate transceivers (530, 550) to perform concurrent transmissions without interfering with the directional transmission of said transceiver, wherein all links associated with said transceiver and said additional transceivers are divided into a number of spatial reuse groups based on a message flow wherein: under a centralized MAC a Coordinator is configured to announce on a control channel a time and a data channel to be used for the directional transmission of an existing link or under a distributed MAC, said transceivers are configured to announce their directional transmissions individually; upon receiving the announcement said additional transceivers (530, 540, 550) are configured to listen for a predetermined time to determine whether the additional transceivers can detect the directional transmission; and each of the additional transceivers are configured to report (440, 445) under a centralized MAC their compatibility with the link under consideration through said control channel. under a centralized MAC a Coordinator is configured to announce on a control channel a time and a data channel to be used for the directional transmission of an existing link or under a distributed MAC, said transceivers are configured to announce their directional transmissions individually; upon receiving the announcement said additional transceivers (530, 540, 550) are configured to listen for a predetermined time to determine whether the additional transceivers can detect the directional transmission; and each of the additional transceivers are configured to report (440, 445) under a centralized MAC their compatibility with the link under consideration through said control channel.
