    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: A method and a wireless transmit/receive unit, WTRU, to facilitate paging in high speed downlink packet access, HSDPA, wireless communications, the method comprising: when the WTRU is in one of a CELL PCH and URA PCH state: receiving, from a base station, HSDPA associated paging indicator channel, PICH, information elements comprising PICH information; compiling a list of candidate PICHs for HSDPA after receiving the information element; determining a value k corresponding to a number of candidates; calculating a selection index equal to:U_RNTI mod k, where U RNTI is a universal mobile telecommunications system (UMTS) terrestrial radio access network (UTRAN) radio network transaction identity (U-RNTI) of the WTRU; selecting a PICH information from the list of candidate PICHs based on the selection index; awakening from a sleep mode during paging occasions derived from the PICH information; monitoring for a paging indicator over a PICH using the selected PICH information; monitoring for a high speed dedicated shared channel, HS-DSCH, radio network transaction identity, H-RNTI; monitoring a high speed shared channel using the received H-RNTI; and returning to the sleep mode, if no H-RNTI is received.

    Abstract: A receiver that reduces impulse response interference using a model of the received signal similar to that used in block linear equalizers. Block linear equalizers comprise decorrelating receivers, zero-forcing receivers, minimum mean square error receivers and the like. The invention comprises an interference computation processor feedback loop (43) for correcting the output of a direct interference canceller (39). The m iterative process removes interferers from the output symbols of a matched-filter (35). The receiver uses received signal models of the various block linear equalizers that do not assume that each subchannel consists of several distinct paths. The receiver ertimates the impulse response characteristic of each subchannel as a whole.

    Abstract: A wireless communication method and system for assigning multi-paths to Rake receiver fingers. A Rake finger assignment database is established in which multi-path signals (300) are categorized into a verified group and an unverified group. Each multi-path is assigned to an individual bin in the database. Each bin includes a pilot phase data field (310), an antenna data field (315), a code data field (320), an averaged signal strength data field (325), an assigned flag data field (330), a verification flag data field (335), an update flag data field (340), an assigned Rake finger number data field (345) and an assignment time counter data field (350). The multi-path signals in the verified group are further categorized into an assigned subgroup and an unassigned subgroup. During a measurement interval, each of a plurality of newly measured multi-path signals is compared to the multi-path signals in the database and is processed accordingly.
