摘要:
A method for use in a wireless transmit receive unit (WTRU) for two-stage reordering of received protocol data units (PDUs). The method comprising receiving PDUs from Node-Bs, wherein each of the received PDUs has a transmission sequence number (TSN), reordering the received PDUs from Node-Bs using the TSN in a MAC layer in different reordering queues, delivering the received PDUs from reordering queues to one logical channel in the RLC layer, reordering the received PDUs in the RLC layer based on a sequence number (SN), starting a timer when at least a RLC PDU is missing based on SN of the RLC PDU, and transmitting a status report indicating a missing RLC PDU based on SN of the RLC PDU if the timer expires, wherein transmission of the status report is delayed if a RLC PDU is missing based on SN of the RLC PDU and the timer is running.
摘要:
Method and apparatus are disclosed for optimizing Random Access Channel (RACH) transmissions from wireless transmit/receive units (WTRUs) for multiple transmissions. A WTRU may initiate uplink transmission for a random access procedure using a configured time resource such that the uplink resources may be time shared by a plurality of WTRUs. The transmission time may be calculated on an absolute or relative basis. A backoff time may be applied before starting the uplink transmission. The backoff time may be WTRU-specific, WTRU group-specific, specified per access class and may be determined based on a priority basis. A scaling factor may be applied to the backoff time. A contention free allocation method may be used to determine the appropriate resource. The data may be transmitted with and without a preamble. The WTRUs may include machine type communication devices and may be grouped in accordance with a number of factors or characteristics.

A method comprising detecting closed subscriber group (CSG) proximity based on an autonomous search function; signaling a proximity indication to a network, wherein the proximity indication includes at least one priority of at least one allowed neighbor CSG cell. A method comprising, performing measurements on neighboring CSG cells; and generating a measurement report including measurements of at least one neighboring CSG cell; and transmitting a message including a measurement report and a CSG priority for at least one CSG cell.
摘要:
Methods and apparatus are disclosed for a wireless transmit/receive unit (WTRU) to detect and perform measurements with respect to Home Node-Bs (HNB) and Home evolved Node-Bs (H(e)NB) (collectively “HNB”). The methods may include generating and transmitting a request for a measurement configuration that may include gap allocations to detect and measure a primary scrambling code or a physical cell identity of a target HNB for at least one frequency or radio access technology (RAT). The request may be in response to the WTRU entering a HNB cell for which the WTRU has stored fingerprint information and whose closed subscriber group ID is in the WTRU's whitelist. The network may configure the WTRU to measure the requested frequency or RAT in response to the proximity report/request. Methods are described for releasing the measurement configuration.
摘要:
Systems and methods are provided for receiving data from multiple cells. A wireless transmit and receive unit (WTRU) may receive data from cells in a multi-point set that includes a primary serving cell and one or more assisting serving cells. The WTRU measures the quality of cells in the multipoint set as well as neighboring cells. Based on the cell quality, the WTRU triggers a reporting event, such cell adding event, cell removal event, or cell replacement event, and sends a measurement report to the network. The WTRU receives an indication of a change to the multi-point set from the network, and modifies the multi-point set accordingly.

摘要:
Methods and apparatus are provided for performing group-based machine-to-machine (M2M) communication. Machine-type communication (MTC) wireless transmit/receive units (WTRUs) may operate in M2M groups. A group of MTC WTRUs may be paged collectively as a group. An MTC WTRU may store an individual international mobile subscriber identity (IMSI) associated with the MTC WTRU, and a group-based IMSI associated with the MTC group that the MTC WTRU belongs to. The MTC WTRU may use one or both IMSIs to receive paging messages. When the MTC WTRU receives a paging message, the MTC WTRU may compare a recipient IMSI contained in the paging message to the individual IMSI and the group-based IMSI. If the recipient IMSI matches the individual IMSI and the group-based IMSI, the MTC WTRU may proceed to process the paging message.
摘要:
A wireless mesh network with digital rights management (DRM) interoperability is disclosed. A first DRM-capable mesh point (MP) performs a discovery procedure for detecting neighbor MPs and identifies at least one other DRM-capable MP among the detected neighbor MPs. The first DRM-capable MP then performs an association procedure only with the DRM-capable MPs. The first DRM-capable MP assigns DRM roles to the associated DRM-capable MPs. A digital content is then distributed from the first DRM-capable MP to another DRM-capable MP via the mesh network. The DRM interoperability may be based on a networked environment for media orchestration (NEMO) architecture proposed by the Coral Consortium or any DRM interoperability architectures.
摘要:
A method and system for enforcing user rights on user data, and maintaining consistency of the user data in a data network are disclosed. Each of a plurality of entities controls one or more network devices which are connected via the data network. Each network device includes at least one user data node which contains at least one elementary piece of user data. The elementary piece of user data is associated with a traceability graph including at least one traceability link. The traceability link connects a source user data node and a destination user data node. The user data node also contains rights information which comprises a rule-based policy regarding the user data. The rights information is also propagated to other entities based on the traceability graph. Consistency of the user data is achieved and owner's rights are enforced based on the traceability graph.
摘要:
A method and system for distributing data to at least one communication device are disclosed. When multiple communication devices request the same data, a seeder sends a different piece of the data to each communication device and the communication devices share the piece of data each other by using a wireless connection established between them. The communication devices automatically suspend and resume downloading of the piece of the data from other communication devices as the communication device performs a handover. The receiver may be given super-distribution rights. When a destination communication device requests data, a content provider identifies a source communication device which possesses the same data and has the source communication device to forward the data to the destination communication device. The source communication device re-encrypts the data with a new encryption key and the destination communication device obtains a license from a rights issuer to decrypt the data.
