[0096] Other implementations are possible. Some variants can be created by simply changing the order of the newly added fields in the frame / message format. Other variations are possible by using only some of the proposed new fields.

[0097] The teachings herein can be implemented as a network with access points to multiple WTRUs at the data link layer, medium access control layer, or network layer, which can be implemented as application specific integrated circuits (ASICs), digital signal processors (DSP) or software. The teaching discloses 802.11 based WLAN systems or OFDM / MIMO using Radio Resource Management (RRM) and Radio Resource Control (RRC), however they can be used in existing and hereafter inverted other types of wireless systems.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application Nos. 61 / 261085 and 61 / 261151, filed November 13, 2009, the contents of which are incorporated herein by reference. technical field [0003] This application relates to wireless communications. Background technique [0004] The earliest version of the IEEE 802.11 standard provided a data transfer rate of 1Mbps. In subsequent revisions, that is, IEEE 802.11b, a physical layer data transmission rate of 11Mbps is provided. With the introduction of Orthogonal Frequency Division Multiplexing (OFDM) in the IEEE 802.11g and IEEE 802.11a revisions for the 2.4GHz and 5GHz bands respectively, the data transmission rate supported at the physical (PHY) layer is increased to 54Mbps. The IEEE 802.11n enhancement increases the data transfer rate supported on top of the MAC layer to 100 Mbps. [0005] Wireless local area networks (WLANs) are being designed with very h...
