摘要： A method and apparatus for wireless communication of multimedia broadcast multicast services (MBMS) data and unicast data using separate downlink carriers and are disclosed. A wireless transmit/receive unit (WTRU) having a single receiver that is switchable to receive either carrier is provided. A network station, such as a Node-B, preferably encodes K MBMS data packets to N MBMS encoded packets using erasure correction coding where N is preferably significantly greater than ( K + v ) which is a determined number of MBMS encoded packets sufficient to recover the K MBMS data packets. The Node-B preferably generates a superframe for carrying the N MBMS encoded packets for each MBMS and transmits the superframe via an MBMS carrier. The Node-B preferably schedules a unicast transmission such that the WTRU is provided with sufficient time to switch to the MBMS carrier to receive at least ( K + v ) MBMS encoded packets per superframe.

摘要： A method for network coding of packets between End Nodes (ENs) and a Relay Node (RN) in wireless communications can be performed at the RN. This method may include: receiving a new packet at the RN from one of the ENs; determining the source node of the new packet at the RN; providing a buffer for each EN; determining whether the buffer associated with the EN that is not the source of the new packet (non-source buffer) has the new packet buffered and based upon such determination, either: (1) storing the new packet in the EN buffer that is the source of the new packet on a condition that the non-source buffer is empty; or (2) network coding the new packet with an existing packet in the non-source buffer.

摘要： A method for multicasting a packet begins by providing a buffer for each of two user equipments (UEs) in communication with a base station. A determination is made whether there is a previously unsent packet at the base station. A second determination is made whether both UE buffers are non-empty. A non-empty buffer is flushed if there is no previously unsent packet and if one of the buffers is non-empty. A packet is selected to be transmitted if there is a previously unsent packet or if both buffers are non-empty. The buffers are updated based on feedback received from the UEs.

摘要： A method and apparatus is used for generating a perfectly random secret key between two or more transceivers in a wireless communication network. In a point- to-point system, both transceivers produce an estimate of the channel impulse response (CIR) based on the received radio signal. The CIR estimation is synchronized and may include error correction and detection. A long secret key of bits is generated from a digitized version of the CIR estimate, from which a perfectly secret encryption key is derived by privacy amplification.

摘要： A method and system for generating a secret key from joint randomness shared by wireless transmit/receive units (WTKUs) are disclosed. A first WTRU and a second WTRU perform channel estimation to generate a sampled channel impulse response (CIR) on a channel between the first WTRU and the second WTRU. The first WTRU generates a set of bits from the sampled CIR and generates a secret key and a syndrome, (or parity bits), from the set of bits. The first WTRU sends the syndrome, (or parity bits), to the second WTRU. The second WTRU reconstructs the set of bits from the syndrome, (or parity bits), and its own sampled CIR, and generates the secret key from the reconstructed set of bits.

摘要： A wireless transmit/receive unit (WTRU) and a Node B, respectively, perform joint randomness not shared by others (JRNSO) measurement to generate JRNSO bits based on a channel estimate between the WTRU and the Node B. The WTRU and the Node B then perform a reconciliation procedure to generate a common JRNSO bits. The Node B sends the common JRNSO bits to a serving network. The WTRU and the SN secure a session key (such as an integrity key, a cipher key and an anonymity key), using the common JRNSO bits. The JRNSO measurements are performed on an on-going basis, and the session key is updated using a new set of common JRNSO bits. The JRNSO bits may be expanded by using a pseudorandom number generator (PNG) or a windowing technique. A handover may be intentionally induced to increase the JRNSO bits generation rate.

摘要： A secret stream of bits begins by receiving a public random stream contained in a wireless communication signal at a transmit/receive unit. The public random stream is sampled and specific bits are extracted according to a shared common secret. These extracted bits are used to create a longer secret stream. The shared common secret may be generated using JRNSO techniques, or provided to the transmit/receive units prior to the communication session. Alternatively, one of the transmit/receive unit is assumed to be more powerful than any potential eavesdropper. In this situation, the powerful transmit/receive unit may broadcast and store a public random stream. The weaker transmit/receive unit selects select random bits of the broadcast for creating a key. The weaker transmit/receive unit sends the powerful transmit/receive unit the selected bit numbers, and powerful transmit/receive unit uses the random numbers to produce the key created by the weaker transmit/receive unit.
