摘要: A method performed by a WTRU may comprise generating a polar factor graph and pruning the polar factor graph to generate a pruned factor graph. The pruned factor graph may include input variable nodes, check nodes and output variable nodes. The method may further comprise the initializing input variable nodes. For each of a plurality of encoding levels of the pruned factor graph, values from the input variable nodes may be transferred to the check nodes. Operations, for example, XOR) additions, may be performed on the values of the check nodes. Check nodes having a single connection to another node not used in a previous transfer may be identified. Values from the identified check nodes may be transferred to the input variable nodes. Binary values from the input variable nodes may be transferred to the output variable nodes for transmission to a receiver.

摘要: A method and apparatus are disclosed for establishing a low latency millimeter wave (mmW) backhaul connection. A base station may receive a mmW relay schedule from an evolved Node B (eNB) within one Long Term Evolution (LTE) scheduling interval. The base station may decode the mmW relay schedule, and initialize a mmW radio transmission resource according to the mmW relay schedule. The base station may receive a data packet from a second base station in a mmW transmission time interval (TTI) based on the mmW relay schedule using the initialized mmW radio transmission resource, and may transmit the data packet to a third base station based on the mmW relay schedule using the initialized mmW radio transmission resource. The transmitting may begin before the reception of the data packet is complete.

摘要: Methods, apparatuses, and systems implemented by a transmitting node (TN), are provided. A representative method implemented by a TN may include generating a first set of polar coded bits (PCBs), sending the first set of PCBs or an interleaved copy of the first set of PCBs in a first transmission, and selecting one code generating operation (CGO) from a plurality of CGOs based on a number of shortened bits associated with the shortening operation. The method may also include storing in a circular buffer a second set of PCBs based on the first set of PCBs or a mother code block (MCB) in accordance with the selected CGO, on condition that the first transmission was not successful, outputting, from the circular buffer, a copy of a part of the second set of PCBs for transmission; and sending the copy of the second set of PCBs in a second transmission.

摘要: Systems and methods related to a multi-server pull-based HTTP request-response structure over ICN systems. In one embodiment, a method comprises: publishing an ICN content request from a cNAP with identification CIDURI; receiving at the cNAP a response from at least one sNAP indicating the availability of the requested content at the at least one sNAP; identifying at the cNAP an optimal segment number, k*, and a set I* of the server IDs, i*, to participate in a network coding based transmission; transmitting the optimal segment number k* from the cNAP to each sNAP identified in the set I*; receiving, at the cNAP, network coding based transmissions from the sNAPs identified in the set I*, and performing decoding of an overall message at the cNAP.

摘要: Methods, apparatus and systems for surrogate server management in an ICN network is disclosed. One representative method may include subscribing, by a network entity, to attribute information to be published; obtaining, by the network entity, the published attribute information; determining, by the network entity, based on the obtained attribute information, whether to activate a virtual machine (VM) to be executed in a surrogate server or to deactivate the VM executing in the surrogate server; and sending, by the network entity to a second network entity, a command to activate or deactivate the VM.

摘要: Methods and apparatuses for receive (Rx) beam selection are described herein. A wireless transmit/receive unit (WTRU) may be configured to receive, from a base station (BS), configuration information for joint communication and sensing (JCS) reference signals. The configuration information may include resources for reference signal transmission and resources for measurement reporting. The WTRU may be further configured to receive, from the BS, an indication to activate a subset of the resources for JCS reference signal transmission. The WTRU may be further configured to transmit, a plurality of JCS reference signals using the activated subset of resources for reference signal transmission. The WTRU may be further configured to measure, via a plurality of Rx beams, a backscatter power associated with each of the transmitted plurality of JCS reference signals. The WTRU may be further configured to calculate beam blockage statistics based on the measured backscatter power.

摘要: Systems, methods, and instrumentalities are described herein that may be used for reduced complexity polar encoding and decoding. There may be a set of encoding nodes to be used for polar encoding. An encoding node may be associated with a bit index and/or a relaxation level. A relaxation attribute may be selected for the encoding node. A relaxation group may be determined based on the relaxation attributes. The relaxation group may include two encoding nodes associated with consecutive bit indexes, an initial relaxation level, and the first relaxation attribute. A final relaxation level may be determined. Relaxation may be performed on the encoding nodes in the relaxation group. For example, an XOR operation between the encoding nodes may be omitted. Relaxation may be performed on the encoding nodes associated with each relaxation level up to the final relaxation level.
