Abstract: A method and apparatus of time synchronizing a plurality of base stations in a wireless communication system includes receiving an indication of a timing associated with a synch burst, where the synch burst is from a mastercell having a better time synchronization quality than other cells and measured by at least one cell other than the mastercell. A request is sent to a wireless transmit/receive unit (WTRU) for a measurement of a base station time of arrival (BSTOA) value of the at least one cell other than the mastercell. The BSTOA value from the WTRU is received and a timing adjustment is sent to the at least one cell other than the mastercell.

Abstract: A method for delivering a short message service (SMS) message to an interworking wireless local area network user equipment (UE) begins by registering the UE with an Internet Protocol short message gateway (IP-SM-GW). A capability report is sent from the UE to the IP-SM-GW, the capability report including the capabilities of the UE. A SMS message is transmitted from a short message service center (SMSC) to the IP-SM-GW. The capabilities of the UE are evaluated at the IP-SM-GW to determine whether the UE can receive the SMS message, and the SMS message is delivered to the UE via the IP-SM-GW if the UE has the capabilities to receive the SMS message.

Abstract: A method and apparatus for transmitting a packet from a transmitter entity to a receiver entity in a wireless communication system are disclosed. A transmitting entity includes a radio link control (RLC) sublayer and lower layers including a medium access control (MAC) sublayer and a physical layer, where the RLC sublayer provides a protocol data unit (PDU) to the lower layers for transmission. The lower layers using a HARQ entity transmit the PDU to the receiving entity. The RLC sublayer in the transmitting entity, without an indication from an RLC sublayer of the receiving entity, provides the PDU in response to an indication from the lower layers for retransmission.

Abstract: A first media independent handover function (MIHF) receives a media independent handover (MIH) capabilities discovery request from a second MIHF and generates a MIH capabilities discovery response message, including one or more parameters. Then the first MIHF then sends the MIH capabilities discovery response to the second MIHF. Based on the information contained in the MIH capabilities discovery response, the first MIHF may receive a handover request message from the second MIHF. The one or more parameters included within the discovery response message indicates the specific technologies for which the first MIHF supports a MMB handover. The one or more parameters may include a list of the technologies for which a make-before-break (MMB) handover is supported. For example, a parameter may use a specific bit structure wherein each bit is a Boolean representation of whether MMB handover is supported for a specific type of technology.

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: The present invention is related to a wireless communication system. 3G UMTS mobile phone systems rely on a protected smart card called the UMTS integrated circuit card (UICC) that provides UMTS subscriber identity module (USIM) applications as a basis or root of various security measures protecting the communication path between the 3G mobile terminal and the UMTS wireless network (or UTRAN). Disclosed is a method by which the UICC exchanges information with a terminal, such as an Internal Key Center (IKC 1250) and a Bootstrapping Server Function (BSF 1270) enables a procedure where multiple local keys specific to applications and Network Application Functions (NAFs) (Ks_local) are used for authentication and to encrypt and decrypt messages.

Abstract: A wireless communication method and apparatus for selecting cells in an orthogonal frequency division multiple access (OFDMA) system are disclosed. A wireless transmit/receive unit (WTRU) measures a downlink path loss of a current serving cell and at least one other cell. The WTRU determines whether a path loss difference between the serving cell and the other cell is below a threshold. If the path loss difference is below the threshold, the WTRU measures a channel quality indicator (CQI) for each of the plurality of subcarrier blocks in the downlink of the current serving cell and the other cell, respectively. The WTRU reports the CQIs to a serving Node-B which selects a new cell based on the CQIs. Alternatively, a centralized access gateway (aGW) may select the new serving cell/Node-B, or the cell selection decision made by the serving Node-B may be forwarded to another Node-B via the centralized aGW.

When used in a wireless local area network, the antenna capability IE can be sent as part of a management frame, control frame, or data frame.

Abstract: Voiceband compression techniques are employed in order to enable an RF telecommunications base station to accommodate data signals of high speed voiceband modems and FAX machines. An Ultra-High Speed Codec supports voiceband modem and FAX transmissions up to 14.4 kb/s and operates using four 16-phase RF slots. Because these codecs transmit information over several RF slots which can be contiguous, the slots within RF communication channels are dynamically allocated. The Dynamic Time slot/Bandwidth Allocation feature detects and monitors the data transmission and forms a data channel from the necessary number of slots.

Abstract: Enhancements are provided for the radio link control (RLC) protocol in wireless communication systems where variable RLC packet data unit (PDU) size is allowed. When flexible RLC PDU sizes are configured by upper layers, radio network controller (RNC)/Node B flow control, RLC flow control, status reporting and polling mechanisms are configured to use byte count based metrics in order to prevent possible buffer underflows in the Node B and buffer overflows in the RNC. The enhancements proposed herein for the RLC apply to both uplink and downlink communications.
