Abstract: An apparatus and methods are provided for paging in a HSDPA connected mode CELL_PCH or URA_PCH state. Preferably, a WTRU is configured to select various PICH information that is broadcast by a base station. The WTRU is preferably configured to receive paging messages, based on the selected PICH information. In one embodiment, a preferred WTRU is configured to receive paging messages, based on a PICH, a HS-SCCH, and a HS-PDSCH. In another embodiment, a preferred WTRU is configured to receive paging messages, based on a PICH and a HS-PDSCH. In both embodiments, a time delay parameter is preferably used so that the WTRU may listen for either the HS-SCCH or HS-PDSCH for a period of time and return to a sleep mode if no paging message is received.

Abstract: Systems, methods, and instrumentalities to select a distributed gateway (D-GW). A WTRU may be configured to detect a request for an address associated with content. The WTRU may receive an address list associated with the content. The WTRU may select a distributed gateway (D-GW). If an address of a currently connected D-GW is included in the address list, the WTRU may select the currently connected D-GW. If the address of the currently connected D-GW is not in the address list and an address of an anchor D-GW that is not currently connected is included in the address list, the WTRU may select the anchor D-GW that is not currently connected. If the address of the currently connected D-GW is not in the address list and the address of the anchor D-GW that is not currently connected is not in the address list, the WTRU may select the currently connected D-GW.

Abstract: A method and apparatus are provided to enable or aid network-controlled selection of an IP address (and anchor) to be used by a WTRU on an application/service basis. In one example, a method is provided for a WTRU to establish a link with a gateway, transmit a query related to a selected application via the gateway, receive an advertisement for an internet protocol (IP) address, and use the IP address to communicate via the gateway with respect to the selected application. It may be assumed that there are more than one possible IP address/anchor available for the WTRU to use, as it might be the case in a mobility environment, in which an operator can provide addresses with different mobility capabilities.

Abstract: Embodiments for enabling traffic content identification by a wireless transmit/receive unit are provided. The WTRU may store interface binding entries in a database associating links in a web page to various traffic content types, such as video, audio, and text. Upon a request to access one of the links, a socket may be created based on a data mobility policy associated with the traffic content type. Alternately, the database may associate the links directly to interface types based on the data mobility policies. The Access Network Discovery and Selection Function (ANDSF) may provide the data mobility policies to the WTRU.

Abstract: A method and apparatus for power control for distributed wireless communication is disclosed including one or more power control loops associated with a wireless transmit/receive unit (WTRU). Each power control loop may include open loop power control or closed loop power control. A multi-phase power control method is also disclosed with each phase representing a different time interval and a WTRU sends transmissions at different power levels to different set of node-Bs or relay stations during different phases to optimize communications.

Abstract: Systems, methods, and instrumentalities are provided to implement content caching. An entity running an external application (EA) may establish a connection between the EA and a centralized cloud controller (CCC) to access a service on the CCC. The EA may receive credentials for access to the service. The connection between the EA and the CCC may be established over a first interface. The EA may send to the service on the CES a query for an available small cell network (SCN) storage. The EA may receive from the service on the CES reply comprising a link to an allocated SCN storage. The EA may ingest one or more contents using the link in the allocated SCN storage. A wireless transmit/receive unit (WTRU) may receive the cached content from an edge server in a small cell network.

Abstract: Systems and/or methods may be used to select an anchor node. For example, a device may detect or more anchor nodes that may be available for the device to connect to. The device may determine whether to handover to one of the detected anchor nodes based on capability information including load information of the anchor nodes. The device may connect to a detected anchor node based on the the capability information including the load information. The detected anchor nodes may be grouped and the device may select and connect to an anchor node based on the groupings. The device may also store a history including a route of the device and anchor nodes on the route and may use such information to determine whether to connect to detected anchor node. The device may further use proximity to content to determine whether to connect to a detected anchor node.

Abstract: Embodiments contemplate that the transfer of an Internet Protocol (IP) address from one (e.g. a first) Gateway (GW) to another (e.g. a second) Gateway (GW) may improve the Dynamic Mobility Management (DMM) handling in any network environment, including a dense network environment. Embodiments contemplate a dense network may enable a User Equipment (UE or wireless transmit/receive unit (WTRU)) to be connected to the closest GW while the IP address transfer may enable the usage of a relatively short data path (e.g. perhaps a “shortest” data path), which may be useful in the context of DMM, perhaps even for existing flows. Using the contemplated capability of moving IP addresses may minimize the number of IP addresses allocated and/or the number of tunnels to be maintained.

Abstract: A wireless transmit/receive unit (WTRU) may detect another WTRU over bluetooth. The WTRU may send to the another WTRU a message to transfer selected media. The WTRU may transfer the selected media to the another WTRU over WiFi.

Abstract: Embodiments contemplate network stack virtualization which may be virtualization of a portion of the communication stack, such as the protocol stack, in some embodiments, multiple functionally of independent copies of the protocol stack may be simultaneously running on the terminal and/or serving the needs of different applications. This may allow independent operation from the application point of view, including connectivity to different networks with different identities. Embodiments contemplate that any number of such virtual network stacks can be instantiated, perhaps in some embodiments depending on the characteristics of an active application. Embodiments also contemplate the presentation of multiple allocated internet protocol (IP) addresses that may have sufficient information to enable an intelligent source IP address selection on the WTRU. The WTRU may be able to select an optimum IP address, perhaps in some embodiments depending on which application may be started.

Abstract: A method and apparatus may be used to receive a first transmission. The first transmission of data bits may have a first redundancy version in a transmission time interval (TTI) from either a first node or a second node. The first transmission may have a first redundancy version in a TTI from both the first node and the second node. The method and apparatus may receive a second transmission of the data bits having a second redundancy version in a second TTI. The second transmission may be received from a different one of the first node, the second node, or both the first node and the second node. The first and second redundancy versions may be different redundancy versions. The method and apparatus may combine the received bits of the first and second transmissions to recover the first data bits.

Abstract: A protocol engine (PE) for processing data within a protocol stack in a wireless transmit/receive unit (WTRU) is disclosed. The protocol stack executes decision and control operations. The data processing and re-formatting which was performed in a conventional protocol stack is removed from the protocol stack and performed by the PE. The protocol stack issues a control word for processing data and the PE processes the data based on the control word. Preferably, the WTRU includes a shared memory and a second memory. The shared memory is used as a data block place holder to transfer the data amongst processing entities. For transmit processing, the PE retrieves source data from the second memory and processes the data while moving the data to the shared memory based on the control word. For receive processing, the PE retrieves received data from the shared memory and processes it while moving the data to the second memory.

Abstract: A method and apparatus for performing Joint Randomness Not Shared by Others (JRNSO) is disclosed. In one embodiment, JRNSO is determined in Frequency Division Duplex (FDD) using a baseband signal loop back and private pilots. In another embodiment, JRNSO is determined in Time Division Duplex (TDD) using a baseband signal loop back and combinations of private pilots, private gain functions and Kalman filtering directional processing. In one example, the FDD and TDD JRSNO embodiments are performed in Single-Input-Single-Output (SISO) and Single-Input-Multiple-Output (SIMO) communications. In other examples, the FDD and TDD embodiments are performed in Multiple-Input-Multiple-Output (MIMO) and Multiple-Input-Single-Output (MISO) communications. JRNSO is determined by reducing MIMO and MISO communications to SISO or SIMO communications. JRNSO is also determined using determinants of MIMO channel products. Channel restrictions are removed by exploiting symmetric properties of matrix products.

Abstract: A method and apparatus are described for supporting dynamic and distributed mobility management (DMM). A wireless transmit/receive unit (WTRU) may attach to a first distributed gateway (D-GW), and configure a first Internet protocol (IP) address based on a prefix locally provided by the first D-GW. The WTRU may move and attach to a second D-GW while carrying out an on-going communication session with a correspondent node (CN). The WTRU may configure a second IP address based on a prefix provided by the second D-GW. The WTRU may use the first IP address for carrying out the on-going session and use the second IP address for a new communication session.

Abstract: 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.

Abstract: A method and apparatus used to transmit and receive weighted data transmissions over a plurality of antennas using a plurality of different pilot signals. Different pilot signals are produced and a different pilot signal of the plurality of pilot signals is transmitted on each of a plurality of antennas. Each of the pilot signals is derived from a pseudo noise (PN) sequence and a bit sequence of the PN sequence for each of the pilot signals is different. A plurality of data streams are produced in which each of the data streams has data bits combined with bits of a PN sequence. The data streams are weighted in response to weight information received from a receiving device and the plurality of weighted data streams are transmitted using the plurality of antennas.

Abstract: Systems, methods, and instrumentalities are disclosed to implement hierarchical policies for local networks. In one representative method, a first local node may establish a dedicated local IP access (LIPA) packet data network (PDN) connection for a local service provided via a local network. The method may include responsive to a request for access to the local service, the first local node receiving a quality of service (QoS) requirement for the requested local service; sending, to a second local node, a dedicated bearer request with a specified QoS level based on a global policy and network-information specific to the local network; and receiving a dedicated bearer response with the specified QoS level.

Abstract: A wireless transmit receive unit (WTRU) may be configured to operate as a gateway, for instance as a remote mobility anchor. The WTRU may establish one or more direct, device-to-device communication links with respective complementary WTRUs. When an established device-to-device link between two WTRUs is lost, one or both of the WTRUs may initiate a fallback procedure to respective fallback gateways. An IP flow that originated over the device-to-device link may be moved to the respective fallback gateways.

Abstract: A method and apparatus may be used in cooperative relays with incremental redundancy (IR) and distributed spatial multiplexing. A wireless transmit/receive unit (WTRU) may listen to the base station (BS) transmission during a first phase of the communication, and use cooperation between a relay station (RS) and the BS for the data transmission during a second phase to improve performance. During the second phase, both the BS and the RS may transmit data to the WTRU, using either distributed Space Time Block Codes/Space Frequency Block Codes (STBC/SFBC) or distributed spatial multiplexing.
