Abstract: Systems and methods for integrating bandwidth management (BWM) equipment into a network in order to manage the use of bandwidth over multiple radio access technologies (RATs) relating to communications between a wireless transmit receive unit and a mobile core network (MCN). When integrating itself into the network, a BWM server may be placed between a MCN and an femto access point. In order for WTRUs to communicate with the MCN through the femto access point and a BWM server, a BWM server may need deep packet inspection capabilities.

Abstract: Methods and base stations are described. A base station includes a receiver, a processor and a transmitter. The receiver receives a first data block associated with an uplink temporary block flow (TBF), and the first data block includes a first header that includes a temporary flow identity (TFI) that identifies the uplink TBF. The processor generate a piggybacked acknowledgement/non-acknowledgement (PAN) field corresponding to the uplink TBF and a PAN check sequence (PCS) based on the PAN field, masks a subset of PCS bits with the TFI to generate a masked PCS, and generates a second data block, associated with a downlink TBF, that includes a second header, a data part corresponding to the downlink TBF, the PAN field, and the masked PCS. The transmitter transmits the second data block.

Abstract: A method and apparatus for indicating a temporary block flow (TBF) to which a piggybacked acknowledgement/non-acknowledgement (PAN) field is addressed. A PAN check sequence (PCS) is created, for example using a cyclic redundancy check (CRC) encoding. The PCS is masked with a temporary flow identity (TFI) assigned to a TBF or a mask generated based on the TFI. A data block including the PAN field and the masked PCS is then processed for transmission. The mask may be generated by converting the TFI using an (M, N) code, M being not greater than the number of bits of the PCS and N being the number of bits of the TFI. With this scheme, a TFI may be transmitted in a PAN field without using explicit bits to identify the TBF.

Abstract: A wireless communication method and apparatus are disclosed for assigning different phases, (i.e., time periods), to perform data transmissions over designated frequency bands in a cooperative relaying system. In phase 1, a relay station (RS) listens to a wireless transmit/receive unit (WTRU) and successfully receives b information bits. In phase 2, the RS and WTRU cooperatively transmit these b information bits to the destination. These transmissions may be performed in a unicast scheme, wherein a WTRU sends information to a selected RS in phase 1, and the RS forwards the information to a base station (BS) in phase 2. The transmission may also be performed in a multicast scheme, wherein the WTRU sends information to the RS and the BS in phase 1, and the RS transmits a subset the information to the BS in phase 2.

Abstract: A method and apparatus are described. A wireless transmit/receive unit (WTRU) generates data bits and piggybacked acknowledgement/non-acknowledgement (PAN) bits and generates a plurality of symbols based on the data bits and the PAN bits. Each symbol of the plurality of symbols represents a plurality of bits and has a least significant bit (LSB) position, and no PAN bits are present in the LSB position of each of the plurality of symbols. The plurality of symbols are transmitted.

Abstract: Methods and apparatus are described. A wireless transmit/receive unit (WTRU) generates a piggybacked acknowledgement/non-acknowledgement (PAN) field and a PAN check sequence (PCS) from the PAN field. The WTRU masks the PCS with a temporary flow identity (TFI) that includes a specific sequence of a plurality of bit values that represents information other than an identification of a particular TBF. The WTRU transmits data that includes the PAN field and the masked PCS.

Abstract: The present invention is related to a method and apparatus for enhancing security of communications. The apparatus comprises a security processing unit, a data processing unit, a cross-layer watermarking unit, and optionally a smart antenna processor. The security processing unit generates a token/key to be used in watermarking and sends a node security policy to other components. The data processing unit generates user data. The cross-layer watermarking unit includes at least one of Layer-2/3, Layer-1 and Layer-0. Each layer performs a different scheme or degree of watermarking. The cross-layer watermarking unit embeds the token/key into the user data transmission on at least one of the layers selectively in accordance with a security policy.

Abstract: Method and apparatus delivering voice/data services within a piconet operating over a limited range or over a WLAN communicating with 3GPP devices by reformatting data into IP format before delivering to the WLAN. The service is short message service (SMS). Upon receipt of an SMS message, relevant routing information is retrieved. A PDGW address for the SMS message is identified and is sent to the PDGW address which identifies the WLAN user equipment (UE) for receiving the SMS and reformats the SMS message into IP format (text or encapsulation) for delivery to the UE. A protocol architecture is provided for SMS delivery over WLANs, in particular, for UMTS/CDMA based SMS over WLAN through two alternative mechanisms, i.e., SMS tunneling and SMS proxy, for protocols for the delivery of SMS across the WLAN. The invention enhances standard 802.11 in the context of UMTS and CDMA 2000; as well as other scenarios.

A gateway device may intercept a communication associated with the device. The gateway device may route the communication such that the communication bypasses a core network. The gateway device may report information associated with the communication to a core network entity. The gateway device may receive a command message. The command message may include a request for a surveillance status of the device. The gateway device may send a response message. The response message may indicate a surveillance status of the device. The gateway device may receive an activate surveillance signal for the device. The gateway device may receive a deactivate surveillance signal for the device. Upon receiving the deactivate surveillance signal, the gateway device may stop further reporting.

Abstract: A method and an apparatus for indicating a temporary block flow (TBF) to which a piggybacked acknowledgement/non-acknowledgement (PAN) field is addressed. A method and apparatus of performing receive processing to reduce the probability of false acceptance of erroneous PANs are also disclosed. A transmit station generates a PAN check sequence (PCS) and performs a channel coding on a PAN field and the PCS. The transmit station scrambles the encoded bits of the PAN field and the PCS with a TBF-specific scrambling code. Because of the scrambling, the PCS decoding at a receive station will pass if the data block is received by an intended receive station, while the PCS decoding will fail if received by a non-intended receive station. Alternatively, the scrambling may be performed before the channel coding. Alternatively, the transmit station may combine the PAN field and a temporary flow identity (TFI) to generate a PCS.

A sequence may be generated from a temporary flow identity (TFI) to which the PAN field is addressed and masked with a PAN check sequence (PCS).

A secondary identifier may indicate a TBF to which the PAN field is addressed. A special value may be used to represent all TBFs assigned and a secondary identifier may indicate a TBF to which the PAN field is addressed. A special value on the PAN field may be used for control purposes for indicating an action affecting a group of receiving stations listening to the radio block.
