摘要： Devices and methods for adjusting resource management procedures in a User Equipment (UE) machine device communicating with one or more nodes in a communication network. In one embodiment, a method includes determining, during a first time period, the number of handovers, N, for the UE from a serving node to a different node. The method further includes comparing the value, N, to a threshold, wherein if the value, N, is greater than the threshold, mobility pattern information for the UE includes an indication of high mobility, and if the value, N, is less than or equal to the threshold, the mobility pattern information includes an indication of low mobility. The method also includes transmitting machine device capability information, including the indicated mobility pattern information, to be used for determining an adjustment to a resource management procedure for the UE.

摘要： The proposed technology provides a computationally efficient way to find suitable routes under consideration of multiple metrics. The considered multi-hop network is represented by a connected graph having nodes and links interconnecting the nodes. The method comprises the step (S1) of obtaining a value of a reference route between a source node and a destination node in the connected graph according a first routing metric. The method further comprises the step (S2) of modifying, based on the value of the reference route according to the first routing metric, the connected graph by modifying link cost, with respect to a second routing metric, of at least one link in the connected graph. The method also comprises the step (S3) of determining at least part of a route between the source node and the destination node in the modified connected graph, based on the modified link cost, according to the second routing metric.

摘要： The iterative decoding of blocks may be continued or terminated based on CRC checks. In an example embodiment, one iteration of an iterative decoding process is performed on a block whose information bits are covered by a CRC. The iterative decoding process is stopped if the CRC checks for a predetermined number of consecutive iterations. In another example embodiment, a decoding iteration is performed on a particular sub-block of multiple sub-blocks of a transport block, which includes a single CRC over an entirety of the transport block. The CRC is checked using decoded bits obtained from the decoding iteration on the particular sub-block and decoded bits obtained from previous decoding iterations on other sub-blocks of the multiple sub-blocks. The decoding iteration is then performed on a different sub-block if the CRC does not check. Also, the decoding iterations for the sub-blocks may be terminated if the CRC checks.

摘要： A Radio Access Network (RAN) (10) and method for rapid handover of a mobile station between a Source Radio Network Controller (SRNC) (12) and a Target Radio Network Controller (TRNC) (21) in the RAN. A mobile station (16) initially served by the SRNC accesses an Enhanced General Packet Radio Service (EGPRS) network (27) through the RAN for conducting a packet-switched call. When handover to the TRNC is required, the SRNC notifies the TRNC that relocation of the mobile station to the TRNC is requested. The TRNC reserves radio resources required to serve the mobile station in the TRNC, and notifies the SRNC that relocation is approved. An Iux interface (11) may be established between the SRNC and the TRNC for direct communication of control signaling. Alternatively, the control signaling between the SRNC and the TRNC may pass through the EGPRS network. The EGPRS begins bi-casting Packet Data Units (PDUs) (44) to both the SRNC and the TRNC until notified by the TRNC that the handover is complete (45). The mobile station is then handed over to the TRNC, and the EGPRS network is notified by the TRNC that the handover is complete. With the Iux interface (11), control signaling that is specific to the RAN does not have to be passed through the EGPRS network.

摘要： The disclosure relates to future radio access systems and more specifically to methods for media access in future radio access systems. The present disclosure presents a method performed in a first node 10c in a wireless communication system, of accessing a shared channel for transmission from the first node to at least one second node 20d. The method comprises the step of receiving, from a third node a pilot signal announcing reception in the third node 10a, wherein the pilot signal comprises information enabling estimation of a channel response from the first node 10c to the third node 10a. The method further comprises estimating, using the pilot signal, a channel response from the first node to the third node and predicting, based on the estimated channel response, an interference level at the receiver of the third node of a directive transmission from the first node to the second node. The method finally comprises accessing the shared channel based on the predicted interference level. The presented method mitigates the problem of hidden nodes for directive transmissions. The disclosure relates to methods for reserving and accessing a shared media in radio access systems, as well as to wireless network nodes.

摘要： Systems and methods are disclosed for adjusting Radio Link Monitoring, RLM, Radio Link Failure, RLF, detection, RLF recovery, and/or connection establishment failure detection for wireless devices (16) in a cellular communications network (10) depending on mode of operation. In one embodiment, a node (14, 16) in the cellular communications network (10) determines whether a wireless device (16) (e.g., a Machine Type Communication, MTC, device) is to operate in a long range extension mode of operation or a normal mode of operation. The node (14, 16) then applies different values for at least one parameter depending on whether the wireless device (16) is to operate in the long range extension mode or the normal mode. The at least one parameter includes one or more RLM parameters, one or more RLF detection parameters, and/or one or more RLF recovery parameters.

摘要： Systems and methods for computing and/or utilizing mutual information based link metrics for a link in a wireless mesh network are disclosed. In one embodiment, one or more mutual information values are computed for a link between a transmitter of a first network node and a receiver of a second network node in a wireless mesh network. Each of the one or more mutual information values is computed for a different hypothesized transmission mode for the link. One or more link metrics for the link are computed as a function of the mutual information values, where each link metric is computed based on a different one of the one or more mutual information values. In this manner, a link metric is computed for each of the one or more hypothesized transmission modes for the link. At least one of the link metrics are then provided to a routing update module.
