1. An apparatus, comprising:
- a transceiver 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 to perform concurrent communications 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 sends an announcement on a control channel including time and a data channel used for the directional transmission, or under a distributed MAC, said transceiver sends an announcement on the control channel including information regarding the directional transmission,upon receiving the announcement, said additional transceivers each determine, for a predetermined amount of time, whether the directional transmission is receive thereby, andeach of said additional transceivers indicate, on the control channel, compatibility with the directional transmission, if that additional transceiver does not hear the directional transmission within the predetermined amount of time, otherwise indicate incompatibility with the directional transmission.

6. A method, comprising:
-
configuring a transceiver for spatial reuse using a virtual time division multiple access (TDMA) technique such that the transceiver sends a directional transmission to a receiving device in a wireless personal area network, wherein the spatial reuse allows additional non -interfering spatially-separate transceivers to perform concurrent communications without interfering with the directional transmission of said transceiver; and defining a number of spatial reuse groups based on division of all links associated with said transceiver and said additional transceivers, said defining including; under centralized MAC, sending, from a Coordinator, an announcement on a control channel including time and a data channel used for the directional transmission, or under a distributed MAC, sending, from said transceiver, an announcement on the control channel including information regarding the directional transmission, upon receiving the announcement, determining, by each of said additional transceivers, for a predetermined amount of time, whether the directional transmission is received thereby, and indicating on the control channel, by each of said additional transceivers, compatibility with the directional transmission, if that additional transceiver does not hear the directional transmission within the predetermined amount of time, otherwise indicating incompatibility with the directional transmission. - View Dependent Claims (7, 8, 9, 10)

11. An article comprising a non-transitory storage-medium having stored thereon instructions, that, when executed by a computing platform, results in:
-
configuring a transceiver for spatial reuse using a virtual time division multiple access (TDMA) technique such that the transceiver sends a directional transmission to a receiving device in a wireless personal area network, wherein the spatial reuse allows additional non-interfering spatially-separate transceivers to perform concurrent communications without interfering with the directional transmission of said transceiver; and defining a number of spatial reuse groups based on division of all links associated with said transceiver and said additional transceivers, said defining including; under a centralized MAC, sending, from a coordinator, an announcement on a control channel including time and a data channel used for the directional transmission, or under a distributed MAC, sending, from said transceiver, an announcement on the control channel including information regarding the directional transmission, upon receiving the announcement, determining, by each of said additional transceivers, for a predetermined amount of time, weather the directional transmission is received thereby, and indicating on the control channel, by each of said additional transceivers, compatibility with the directional transmission, if that additional transceiver does not hear the directional transmission within the predetermined amount of time, otherwise indicating incompatibility with the directional transmission. - View Dependent Claims (12, 13, 14, 15)
