Abstract: A method and apparatus for transmitting and receiving via a high speed downlink shared channel (HS-DSCH) is disclosed. A wireless transmit/receive unit (WTRU) receives the HS-DSCH while operating in a cell forward access channel (Cell-FACH) state, a cell paging channel (Cell-PCH) state, or URA paging channel (URA-PCH) state.

Abstract: A method and apparatus for adjusting a channel quality indicator (CQI) feedback period to increase uplink capacity in a wireless communication system are disclosed. The uplink capacity is increased by reducing the uplink interference caused by CQI transmissions. A wireless transmit/received unit (WTRU) monitors a status of downlink transmissions to the WTRU and sets the CQl feedback period based on the status of the downlink transmissions to the WTRU. A base station monitors uplink and downlink transmission needs. The base station determines the CQI feedback period of at least one WTRU based on the uplink and downlink transmissions needs and sends a command to the WTRU to change the CQl feedback period of the WTRU. A WTfRU MONITORS A STATUS OF 102 DOWNLINK TRANSMiSSIONS TO THE WTRU. THE WTRU SETS THE CQt FEEDBACK PERIOD BASED ON THE STATUS OF DOWNUNK TRANSMISSIONS TO THE WTRU, (START 20 A BASE STATION MONITORS UPLINK TRANSMISSION NEEDS AND DOWNUNK TRANSMISSION NEEDS.

Abstract: A wireless transmit/receive units (WTRUs) receives a downlink transmission from a Node-B and decodes the downlink transmission. If the decoding is not successful, the WTRU sends a pre-defined burst signifying a negative acknowledgement (NACK) to the Node-B via a contention-based shared feedback channel. The pre-defined burst may be sent only once without requiring an acknowledgement. The Node-B calibrates a downlink transmit power so that the downlink transmission is transmitted to the WTRUs with a high likelihood. The Node-B may send a downlink transmission including multiple data streams processed using different modulation and coding schemes so that a WTRU having a high signal quality decodes all data streams while a WTRU having a low signal quality decodes less than all data streams. The Node-B sends a channel quality indicator (CQI) threshold so that each WTRU determines a data stream to report feedback based on the CQI threshold and a measured CQI.

Abstract: This invention relates to wireless local area networks, and particularly to the IEEE 802.11 family of standards. It consists of a method and apparatus that can be implemented in access points (APs) and subscriber wireless transmit/receive units (WTRUs), in order to allow an AP to initiate re-association of a WTRU to itself or a different AP. The invention improves the robustness of the network by enabling more efficient load balancing, congestion control, and roaming, without compromising the user experience.

Abstract: A method and apparatus for No-TX mode for a wireless transmit/receive unit (WTRU) and Node B that suspends the transmission of power control 5 updates and associated signaling over dedicated uplink and downlink channels. Triggers and signals between the WTRU and Node B activate and disable No-TX mode. A radio link is re-established to resume data transmission when No-TX mode is disabled, and data may also be transmitted during defined transmission opportunities while in No-TX mode.

Abstract: 5 An improved method of network management, particularly in the context of standards IEEE802.11 and IEEE802.11k, through two new MAC measurements, with attendant advantages. The two new measurements include WTRU uplink traffic loading measurement, and an AP service loading measurement and is generally applicable at least to layers 1 and 2 as applied to at least 802.11k in the 10 context of OFDM and CDMA 2000 systems, but is applicable to other scenarios as well. A method for determining and advertising congestion is also provided for a Wireless Local Area Network (WLAN) system. The present invention also introduces a method for managing congestion when congestion is detected. This aspect for the present invention applies primarily to wireless systems that use the 15 Carrier Sense Multiple Access/ Collision advantageously implemented in selectively configured WTRUs of various forms.
