Abstract: A system and method for improving the link adaptation in a wireless communication system is disclosed. User Equipment (UE) forms an interference hypothesis by amending a measured interference and noise by artificially injecting, to the measured interference and noise, interference corresponding to at least one emulated interfering isotropic signal that is virtually transmitted over an associated estimated effective channel. The UE further determines at least one channel state information (CSI) report based on the interference hypothesis, and transmits the CSI report to the network.

Abstract: Fuel cell batteries are provided, and in particular hydrogen fuel cell batteries composed of at least one stack of cells. The battery is divided into at least two groups of cells able to be supplied with hydrogen separately. In a first phase, only the first group of cells and not the second is supplied; unconsumed hydrogen may however flow between the two groups via at least one evacuation manifold connected to the cells of the two groups. In a second phase, the supply to the two groups is reversed, unconsumed hydrogen still being able to flow between the two groups via the evacuation manifold. In a third phase, after a series of alternations of the two first phases, the two groups are first simultaneously supplied, then a purge valve of the evacuation manifold is opened then closed.

Abstract: Example embodiments presented herein are directed towards the management of a Maximum Transfer Unit (MTU) related path failure. The example embodiments comprise an originating node, or a node sending a data message, identifying a path with a re-transmission count that is equal to or greater than a predetermined heartbeat threshold value. The originating node further extends a heartbeat message size according to a maximum message transfer size. The originating sends the extended heartbeat message of the identified path and manages the identified path based on results of the extended heartbeat message transmission.

Abstract: A method and apparatus for handling Packet Data Network (PDN) connections between a 3GPP core network node and a User Equipment (UE) via a non-3GPP access network. The UE sends to a gateway node in the non-3GPP access network a first message requesting establishment of a PDN connection. The UE obtains a key associated with the PDN connection and subsequently sends to the gateway node data packets relating to the PDN connection, each data packet including the key. The key allows the gateway node to identify the PDN connection even when multiple PDN connections are used by the UE.

Abstract: Methods and systems present solutions to, for example, the problem of unnecessary preparedness for suspended retransmissions in the user equipment (UE) which contributes to power drain in the device battery. One method for monitoring a Physical Downlink Control Channel (PDCCH) for adaptive retransmission grants in a radio communication system includes: monitoring, by a user equipment (UE), the PDCCH for adaptive retransmission grants; receiving, by the UE, a hybrid automatic repeat request (HARQ) acknowledge (ACK) message, and ceasing, by the UE, to monitor the PDCCH for adaptive retransmission grants after receipt of the HARQ ACK message.

Abstract: According to the teachings herein, an LTE or other wireless communication network provides for independent control of SRS transmissions by a UE or other wireless device. The network advantageously sends DCI messages for SRS power control using a modified format 3/3A, where the message length conforms to that used for conventional format 3/3A messages but where the message is masked using a distinct RNTI. Correspondingly, the wireless device is configured to recognize from the distinct RNTI that the received TPC commands are targeted to controlling the uplink transmit power used by the wireless device for SRS transmissions.

Abstract: The present invention relates to a method and a positioning server in a radio access network for collecting radio fingerprint positioning data records from different nodes. The data records comprise geographical positions and radio network communication parameters and are stored and grouped in clusters in the positioning server. A geometrical shape representing a geographical area based on the network communication parameters in the collected positioning data records in the cluster is computed. When a notification about changed network configuration parameters for a radio cell is received, known positioning servers simply erase all positioning data records related to that radio cell. This results in the unavailability of still valid positioning data. The present invention overcomes this problem by selectively erase positioning data records in the positioning server only when the configuration parameters have changed beyond a predefined value range.

Abstract: The set of resource aggregation levels available for forming an enhanced control channel message may vary from one subframe to another, based on the level of puncturing in the transmitted subframes. An example method begins with determining (2710) members of a set of aggregation levels usable to aggregate the non-overlapping subsets of resource elements for transmitting downlink control information. This determining is based on a puncturing level to be used for the transmission of the downlink control information. Downlink control information for the given subframe is mapped (2720) to one or more non-overlapping subsets of resource elements in the at least one block of time-frequency resources, according to an aggregation level selected from the determined set, and then transmitted (2730), in the one or more non-overlapping subsets. This method may be repeated for each of several subframes, where the puncturing may differ from one subframe to another.

Abstract: A method for routing a terminating call to a user equipment via a first control node for controlling the call, wherein the user equipment is attached to a second control node which is adapted to provide routing information. The method comprises determining, by the second control node, if the user equipment is attached to the second control node over a third control node, wherein the attachment over the third control node indicates that call control shall be performed by a specific service domain. Based on the determining, the provided routing information is selected by the second control node, wherein the routing information indicates to the first control node if the further call establishment to the user equipment is controlled either by the second control node or by the third control node. The call is then routed, by the first control node, according to the selected routing information.
