Abstract
High throughput channel operation in a mesh wireless local area network (WLAN) is disclosed. A mesh network comprises a plurality of mesh points and a network management entity (NME). The NME is configured to retrieve capability and configuration data from the mesh points. The NME configures at least one mesh point with respect to IEEE 802.11n channelization and legacy protection mode based on the capability and configuration data.
Claims21
An access point (AP) comprising:
- a wireless receiver configured to receive, from each of a plurality of wireless transmit receive units (WTRUs), configuration information, wherein configuration information received from at least one of the plurality of WTRUs includes information regarding coexistence of a 20 MHz channel and a 40 MHz channel, green field protection information, space time block coding (STBC) information, and legacy signal field (L-SIG) transmission opportunity (TXOP) protection information;
- and
- a wireless transmitter configured to transmit, to at least one of the plurality of WTRUs, instructions for controlling operation of the at least one of the plurality of WTRUs regarding IEEE 802.11n channelization and legacy protection, wherein a content of the instructions for controlling the operation of the at least one of the plurality of WTRUs regarding IEEE 802.11n channelization and legacy protection is based at least on the configuration information from each of the plurality of WTRUs.
A wireless transmit and receive unit (WTRU) comprising:
- a wireless transmitter configured to transmit configuration information, wherein the configuration information includes information regarding coexistence of a 20 MHz channel and a 40 MHz channel, green field protection information, space time block coding (STBC) information, and legacy signal field (L-SIG) transmission opportunity (TXOP) protection information;
- and
- a wireless receiver configured to receive instructions for controlling operation of the WTRU regarding IEEE 802.11n channelization and legacy protection, wherein a content of the instructions for controlling the operation of the WTRU regarding IEEE 802.11n channelization and legacy protection is based at least on the configuration information.
