摘要： A method and apparatus performs processing of the non-access stratus (NAS) layer (layer 3) in long term evolution (LTE) wireless transmit/receive units (WTRUs), which allows the NAS protocol layer to route layer 3 messages to the correct NAS entity, and to encode new NAS message types and information elements. A new architecture is presented that enables NAS security. When a NAS message is generated, a determination is made as to whether or not to cipher, de-cipher and/or integrity check the NAS message based on at least one of a protocol discriminator (PD) of the NAS message, an indicator field in a header of the NAS message, the type of the NAS message, a NAS security state variable, and an indication by an upper layer protocol. The NAS security state variable indicates whether NAS security is currently active or not and may comprise one bit.

摘要： A method and a wireless transmit/receive unit (WTRU), including a universal subscriber identity module (USIM), for identifying a closed subscriber group (CSG) cell are disclosed. The WTRU receives a broadcast from a cell including a cell identifier (ID). If the cell ID is associated with a CSG cell, the WTRU determines whether the CSG ID is programmed in the USIM. The cell broadcast may include a single bit information element (IE) indicating that the cell is a CSG cell. If the cell ID is a CSG ID, the cell ID may further include a plurality of fields which indicate at least one of a country, a region, an operator, and a home evolved Node-B (HeNB) number. The cell broadcast may further include a bit indicating whether the CSG cell is public or private. The cell broadcast may further include a bit indicating that emergency calls are allowed from all users.

摘要： Detecting, avoiding and/or correcting problematic puncturing patterns in parity bit streams used when implementing punctured Turbo codes is achieved without having to avoid desirable code rates. This enables identification/avoidance of regions of relatively poor Turbo code performance. Forward error correction comprising Turbo coding and puncturing achieves a smooth functional relationship between any measure of performance and the effective coding rate resulting from combining the lower rate code generated by the Turbo encoder (600) with puncturing of the parity bits. In one embodiment, methods to correct/avoid degradations due to Turbo coding are implemented by puncturing interactions when two or more stages of rate matching (610, 620) are employed.

摘要： A channel estimation method which reduces the strain on resources of a Rake receiver using a complex weight gain (CWG) algorithm. In one embodiment, a non-adaptive algorithm is used to average blocks of pilot symbols from several slots. In another embodiment, an adaptive algorithm implements sliding window averaging or a recursive filter. Using a CWG algorithm reduces the memory and processor requirements of the Rake receiver.

摘要： A method and apparatus are described for connecting nodes in an opportunistic multi-medium access control (MAC) aggregation (OMMA) network. A station (STA) on an STA side of the OMMA network may associate with an access point (AP) on an AP side of the OMMA network. The AP may transmit a first association notification message to a first node on the AP side of the OMMA network. The STA may transmit a second association notification message to a second node on the STA side of the OMMA network. An OMMA controller application (OCA) in the first node may populate or update an entry in an available STA MAC address table based on the MAC addresses in the first association notification message. The second node may transmit to the first node a client OCA notification.

摘要： A method and apparatus are described for maintaining communications connectivity for client applications that send keep-alive messages and network applications that send client-alive (i.e., "are you there?") messages. The client applications may register with a client proxy provided in an operating system (OS) of a wireless transmit/receive unit (WTRU) and indicate a respective keep-alive message signaling rate. The network applications may register with a network proxy provided in an OS of a network node and indicate a respective client-alive message signaling rate. The client proxy and/or the network proxy may, respectively, register and prioritize keep-alive and/or client-alive message requirements, determine an optimal signaling rate based on the respective keep-alive and/or client-alive message signaling rates, and generate proxy messages, (i.e., an application layer proxy keep-alive message and/or a network layer proxy client-alive message), associated with the keep-alive and/or client-alive messages. The proxy messages may be transmitted at the optimal signaling rate.

摘要： A method and apparatus are described for updating metadata, (e.g., media presentation descriptions (MPDs)). A wireless transmit/receive unit (WTRU) may transmit a hypertext transport protocol (HTTP) request message and receive an HTTP response message including metadata requested by the HTTP request message. The WTRU may then register with at least one server to establish a metadata update service based on information included in the metadata. The WTRU may fetch updated metadata in response to receiving a metadata update signal provided by the metadata update service. The information may identify a uniform resource identifier (URI) or a fully qualified domain name (FQDN) associated with an event server used to provide the metadata update service.

摘要： A method is described for establishing an end-to-end multipath connection between two peers using of a multi-connection transport protocol (MCTP) architecture. The MCTP architecture may include a packet scheduler, a queue configured to store a plurality of packets received from the packet scheduler in a particular sequence, a sub-flow manager configured to distribute the packets among a plurality of sub-flows, wherein at least two of the sub-flows are synchronized, and a synchronized congestion controller (SCC) configured to control congestion of the synchronized sub-flows. A first transmission control protocol (TCP) positive acknowledgement (ACK) may be generated when a first TCP packet is received over one of the synchronized sub-flows. Duplicate TCP packets received after the first TCP packet is received may be discarded. ACKs received after the first ACK may be discarded if they correspond to a TCP packet that was already acknowledged.
