摘要： 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.

摘要： In a wireless communication system including at least one wireless transmit/receive unit (WTRU) and at least one Node-B (NB), an activation or deactivation state is determined for each of a plurality of HARQ processes. A signal that includes the activation or deactivation state for each of the HARQ processes is transmitted to the WTRU. In response to receiving the signal, the WTRU activates or deactivates a particular HARQ process in accordance with the activation or deactivation state for each of the HARQ processes contained in the received signal.

摘要： Methods and apparatus for mitigating in-device interference are described. The methods may include an in-device interference event (e.g. an interference situation), and the processing of events may depend on the priority of the technologies. A handover to another frequency or radio access technology (RAT) may occur in case a co-existing technology may be activated. The network may signal to the device a list of frequencies or RATs that it may be allowed to measure and handoff to. A network may provide a scaling value that the device may use to speed up reaction to the interference. The device may apply a scaling factor to an “out of synch’ counter and/or the radio link failure (RLF) timer used for the RLF procedure. The device may apply different scaling factors for the measurements and time to trigger events. The device may trigger a report to the network requesting gaps for an alternate RAT.

摘要： 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.

摘要： 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 a least 802.11k in the 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 of the present invention applies primarily to wireless systems that use the Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) mechanism. The methods are advantageously implemented in selectively configured WTRUs of various forms.
