A loss correction encoding device having an improved capability of loss correction using LDPC-CC includes a rearranging unit that rearranges information data contained in n information packets according to the constraint length Kmax and the encoding rate (q−1)/q of a check polynomial of the loss correction code used in a loss correction encoding unit. Specifically, the rearranging unit rearranges the information data in such a way that continuous Kmax×(q−1) pieces of information data after rearrangement are contained in different information packets. The rearranging unit distributes the information data to information blocks from n information packets, where n satisfies the formula Kmax×(q−1)≤n.

A transport framework for heterogeneous data streams includes session management module and a connection management module. The session management module is configured to receive a request to establish a first stream that is used for transmitting or receiving data, where the request includes an express indication as to whether the first stream is reliable or unreliable; construct a first data frame based on application data; handoff the first data frame to the connection management module; and maintain a record for the first data frame that includes whether the first data frame is successfully transmitted to the receiver. The connection management module is configured to receive the first data frame of the first stream from the session management module; receive a second frame from the session management module; encapsulate the first data frame and the second frame in a packet; and transmit the packet to the receiver using an unreliable protocol.

A method performed by a user equipment (UE) wirelessly connected to a wireless communication network for facilitating transmission of a real-time media flow from a sender towards the UE is described. The method includes sending a request to the network, requesting a packet loss prediction and a throughput prediction for transmission of a real-time media flow from the network towards the UE. The method also includes receiving, from the network, information of a predicted UE throughput and a predicted UE packet loss predicted by the network in response to the sent request. In some embodiments, the method also includes sending the received information to a sender of the real-time media flow to the UE.

Devices, computer-readable media, and methods for selecting a type of packet loss protection for a network-based communication based upon a latency estimate are disclosed. For example, a processing system including at least one processor may obtain a latency estimate for a network-based communication, determine whether the latency estimate exceeds a latency threshold for selecting a type of packet loss protection, and select, the type of packet loss protection for the network-based communication from among a first type of packet loss protection and a second type of packet loss protection based upon the determining. When the latency estimate is determined to not exceed the latency threshold, the first type of packet loss protection is selected. When the latency estimate is determined to exceed the latency threshold, the second type of packet loss protection is selected.

A method and apparatus for allocating resources to a wireless transmit receive unit (WTRU) includes the WTRU transmitting a signature sequence to a Node B, receiving an acknowledge signal from the Node B, and determining a default resource index. The resource index is associated with enhanced dedicated channel (E-DCH) parameters.

Embodiments provide a method and an apparatus including: A first terminal apparatus determines at least one of a reception capability parameter or a transmission capability parameter based on a first parameter, where the reception capability parameter includes a quantity of channels that can be received in a first time interval, the transmission capability parameter includes a maximum quantity of transmitted bits, and the first parameter is configured by a network device, where the first parameter includes one or more of the following: a maximum interval between slots of initial transmission and last retransmission, a subcarrier spacing, and a sub-band size.

A communication technique and a system for fusing a 5.sup.th generation (5G) communication system with Internet of things (IoT) technology for supporting a higher data rate after a 4.sup.th generation (4G) system is provided. The disclosure can be applied to intelligent services (e.g., a smart home, a smart building, a smart city, a smart car or a connected car, healthcare, digital education, retail, security and safety related services, and the like), based on 5G communication technology and IoT related technology. The disclosure provides a method and an apparatus for indicating an alternative resource in the event of a collision of configured grants.

A method and apparatus for selecting a sidelink resource for a sidelink CSI reporting in a wireless communication system is provided. A first wireless device triggers the SL CSI reporting for the PC5-RRC connection. A first wireless device determines to create a sidelink grant corresponding to transmission of a single MAC PDU based on the triggered SL CSI reporting or a SL data available for transmission. A first wireless device triggers a resource selection procedure based on the determination. A first wireless device selects a sidelink resource in the resource selection procedure.

A resource such as a server derives multiple streams of data based on particular content. Each of the multiple streams of data is encoded to enable play back of the content according to a different level of quality. The server transmits the multiple streams of data of differing levels of quality on a multicast link downstream to one or more intermediate nodes that, in turn, distribute the streams of data to end users. For example, an intermediate node retrieves a respective stream of data from the multiple streams of data and forwards the selected stream of data over a second portion of the multicast link to a respective client device. The intermediate node can transmit a different stream of data to the respective client device depending on available bandwidth. The client device plays back the transmitted stream of data to produce a rendition of the particular content.

A wireless device receives configuration parameters of one or more configured grants of an unlicensed cell. The wireless device receives a downlink control information indicating an uplink grant for a first TB corresponding to a first HARQ process. The wireless device stores, based on a first LBT procedure indicating a busy channel, the first TB in a first HARQ buffer associated with the first HARQ process. The first LBT is for a scheduled transmission of the first TB. The wireless device flushes, based on a second LBT procedure indicating a busy channel, a second HARQ buffer associated with a second HARQ process. The second LBT procedure is for a scheduled transmission of a second TB via a first configured grant of the one or more configured grants.
