    Abstract: A method and apparatus for sending a channel quality indication (CQI) via a shared channel while a wireless transmit/receive unit (WTRU) is in a Cell_FACH state without having a dedicated channel allocated for the WTRU are disclosed. A WTRU performs a measurement of at least one parameter and generates a CQI based on the measurement. The WTRU then transmits the CQI via a random access channel (RACH). The CQI may be transmitted using an RACH preamble. A plurality of signature sequences may be divided into a plurality of groups. The WTRU may select one group based on the CQI and randomly select a signature sequence among signature sequences in the selected group for transmitting the RACH preamble. The CQI may be appended to the RACH preamble. The CQI may be transmitted via a control part or a data part of the RACH message.

    Abstract: A METHOD AND SYSTEM FOR IMPROVING RESPONSIVENESS IN EXCHANGING MANAGEMENT AND CONTROL FRAMES IN A WIRELESS LOCAL AREA NETWORK ARE DISCLOSED. AN INITIATOR (102, 202, 302, 402, 502, 602) SENDS A FRAME (ACTION, MANAGEMENT, CONTROL OR DATA FRAME) TO A RESPONDER (104, 204, 304, 404, 504, 604). UPON CORRECTLY RECEIVING THE FRAME, THE RESPONDER (104, 204, 304, 404, 504, 604) SENDS A RESPONSE FRAME TO THE INITIATOR (102, 202, 302, 402, 502, 602) INSTEAD OF DIRECTLY SENDING AN ACKNOWLEDGEMENT, ACK PACKET. THE RESPONDER (104, 204, 304, 404, 504) PREFERABLY ACCESSES THE WIRELESS MEDIUM TO SEND THE RESPONSE FRAME IN A SHORT INTER-FRAME SPACING, SIFS. WITH THIS SCHEME, A LONG DELAY ASSOCIATED WITH HAVING TO CONTEND FOR THE WIRELESS MEDIUM TO SEND THE RESPONSE FRAME IS AVOIDED AND THEREFORE, THE RESPONSIVENESS AND TIMELINESS OF THE FEEDBACK MECHANISM IS SIGNIFICANTLY ENHANCED. THE RESPONSE FRAME MAY BE PIGGYBACKED ON OR AGGREGATED WITH ANOTHER PACKET. THE MOST ILLUSTRATIVE DRAWING IS

    Abstract: A peer-to-peer communication system using a direct link setup (DLS) is disclosed. A mobile station (STA) establishes a direct communication link with another STA by sending a message requesting a DLS to an access point (AP), (i.e., a centralized controller). The AP may accept or reject the DLS request based on channel measurements. If the DLS request is accepted, the DLS is established such that the STAs may directly communicate with each other. An established DLS connection may be torn down by the AP sending a message including a DLS teardown request to one of the STAs, or based on channel measurements. The system may be an AD hoc network including a plurality of STAs without an AP where each STA maintains a database of one-hop and two hop STAs, and establishes a direct link to other STAs after informing neighboring STAs of an intention to establish a direct communication link. 1Q, 104 114-- 106 120 108- LO1= E 12a QSTAb ST

    Abstract: A method and system applies MAC transmission opportunity (TXOP) protection for multiple mode operation in a WLAN system. In particular, MAC mechanisms are defined to support multiple mode CTS frames, and multiple mode CF-End frames sent by the AP, each in a format appropriate for the corresponding mode which also applies to a single mode as a trivial case. MAC mechanisms permit truncation of TXOP duration for releasing the unused portion of the TXOP when no further data for transmission is available. Release of unused protected TXOP is possible for both protected AP transmissions. K=Z11/17 * Lai W *~ ( \ ( D C'A -S u0 10- 0- 1 SA iIs00 C Uj LU Co C-a Sils LiLU CD:: v)~~ LL U

    Abstract: A METHOD AND SYSTEM APPLIES MAC TRANSMISSION OPPORTUNITY (TXOP) PROTECTION FOR MULTIPLE MODE OPERATION IN A WLAN SYSTEM. IN PARTICULAR, MAC MECHANISMS ARE DEFINED TO SUPPORT MULTIPLE MODE CTS FRAMES, AND MULTIPLE MODE CF-END FRAMES SENT BY THE AP, EACH IN A FORMAT APPROPRIATE FOR THE CORRESPONDING MODE WHICH ALSO APPLIES TO A SINGLE MODE AS A TRIVIAL CASE. MAC MECHANISMS PERMIT TRUNCATION OF TXOP DURATION FOR RELEASING THE UNUSED PORTION OF THE TXOP WHEN NO FURTHER DATA FOR TRANSMISSION IS AVAILABLE. RELEASE OF UNUSED PROTECTED TXOP IS POSSIBLE FOR BOTH PROTECTED AP TRANSMISSIONS AND STA TRANSMISSIONS.
