Abstract: There is provided a method, performed by a network node, for steering of access between cells. The method comprises receiving (1301), from user equipment, a report indicating failure to access a cell, also referred to as a rejecting cell, due to internal reasons of another network node, also referred to as a rejecting network node, serving the rejecting cell. The method also comprises steering (1302) the access of the user equipment between cells by modifying at least one offloading parameter and/or threshold based on the report indicating failure to access the rejecting cell due to internal reasons of the rejecting network node serving the rejecting cell. With this new type of report the network can modify offloading parameter(s) and/or threshold(s) in a more suitable way since the network has more information available.

Abstract: This disclosure details example methods and apparatuses for a wireless communication network and for devices operating in such networks that reduce or eliminate the need for performing random access procedures to obtain appropriate Timing Advance, “TA”, values for use with new TA groups that include cells split from an existing TA group and/or new cells not in any existing TA groups defined for a given device. It is advantageously recognized herein that a TA relationship between one or more cells in an old or existing TA group of a device and one or more cells in a new TA group of the device may be known or otherwise estimated, e.g., based on known delay differences, cell sizes, etc. The TA relationship is used to initialize the TA value used for the new group, e.g., by copying or offsetting the current TA value of the old or existing TA group.

Abstract: A UE (30) configured in multi-carrier with at least one secondary cell (SCell) may send feedback signaling to the network when measurement gaps are active, which prevent the UE (30) from communicating on the primary cell (PCell). Criteria, signaling means, and pre-defined rules are described for selecting feedback signaling and for selecting the alternative cell (e.g., suitable SCell) for transmitting the selected feedback signaling to the network node during the measurement gaps. Similarly, a SCell may be used to receive scheduling information during measurement gaps.

Abstract: Techniques for avoiding or reducing unnecessary CSI and/or SRS transmissions in a wireless communications system. In an example method, a user terminal periodically transmits (620) CSI and/or SRS according to corresponding periodic CSI transmission opportunities or periodic SRS transmission opportunities, or both, during a first period in which the UE is operating according to a short DRX cycle. In a second period immediately following the first period and during which the user terminal is operating according to a long DRX cycle, the user terminal reduces or suppresses (630) periodic transmissions of CSI and/or SRS. This may be done, for example, by suppressing periodic transmission of CSI and/or SRS, after a first delay time or first delay times or by reducing the rate of transmission of CSI and/or SRS, after a second delay time or second delay times. A combination of these and other disclosed approaches may be used.

Abstract: A method, implemented in a first node, that is in communication with a second node and a mobile device, includes determining a traffic type of a first traffic bearer within a packet data network connection between the second node and the mobile device. The method further includes marking the first traffic bearer as movable or non-movable based on the determined traffic type. The method also includes in response to determining that the first traffic bearer has been marked as non-movable, marking all other traffic bearers in the packet data network connection between the second node and the mobile device as non-movable.

Abstract: The technology presented in this disclosure pertains to telecommunication. For example, there is presented a method of operating a wireless terminal 30. A timing advance command (TAC) control element (CE) is received over a radio interface (from a network node 28). Upon receipt of the TAC CE, the method continues by updating UL (uplink) transmission timing for cells in a timing advance (TA) group even when a TA timer for the associated TA group is not running.

Abstract: According to a first aspect of embodiments herein, the object is achieved by a method in a terminal for handling a timing reference. The terminal is served by multiple serving cells of a wireless network, and is configured with a first Timing Advance, TA, group comprising the multiple serving cells, one of which, a current TR cell, acts as the timing reference for the multiple serving cells. When the current TR cell becomes unavailable for the terminal, the terminal autonomously selects a new TR cell to act as the timing reference for the multiple serving cells in the TA group.

Abstract: A method is provided in a user equipment node for dynamically selecting a random access response window value for use with random access procedures in a network. The method comprises the step of determining if a random access response window value is being signalled from the network for a first serving cell currently associated with the user equipment node. If so, the random access response window value being signalled for the first serving cell is used when performing a random access procedure in the first serving cell. If not, an alternative random access response window value for the first serving cell is used when performing a random access procedure in the first serving cell.

Abstract: Method and mobile node in a wireless communication network for determining when to transmit a signal. The mobile node operates in a wireless communication network comprising a first cell and a second cell where the mobile node is synchronized to the first cell. The method comprises determining a timing reference based on a reception of a downlink transmission in the first cell and transmitting the signal, to be received in the second cell, at a point in time based on the timing reference and a timing advance value of the first cell.

Abstract: According to some embodiments, a wireless communication device within a coverage area of a first network is configured to act according to first configuration information associated with the first network. The wireless communication device detects when it has moved outside the coverage area of the first network and, in response, applies an out-of-coverage configuration management rule. The rule indicates how to manage the first configuration information outside the coverage area of the first network.

Abstract: A method, performed in a user equipment (UE) includes: saving a timing advance (TA) value when a TA timer associated with the TA value expires, the TA value indicating when the UE should start its uplink transmission before a nominal time given by the timing of a downlink signal received by the UE; and starting the TA timer in response to the UE receiving a TA command from an evolved Node B while the TA value is saved, the TA command containing an update for the TA value. A corresponding UE is presented.

Abstract: QoS is built into a peer network within existing Internet infrastructure itself lacking QoS, by enabling a network peer to continuously discern the network's ability to deliver to that peer a particular Content Object (distributed in groups of component Packages among neighboring VOD peers) within predetermined times. Content Objects are divided into groups of component Packages and distributed to Clusters of neighboring network peers, enhancing QoS upon subsequent retrieval. Tracking Files (lists of network peers storing Package groups) and Tracking Indexes (lists of network peers storing Tracking Files) are generated to facilitate “on demand” Content Objects retrieval. Dynamically monitoring network traffic (including VOD functionality, bandwidth and reliability) creates “distributed closed-loop feedback,” and in response, attributes of individual network peers (e.g., Trust Level and membership within a particular Cluster) are modified, and “content balancing” functions performed (e.g.

Abstract: Some of the example embodiments presented herein are directed towards a user equipment (501), and corresponding method therein, for uplink timing alignment. The user equipment (501) may initiate a timing advance value to zero during a creation of a timing advance group, a modification of a timing advance group, or if a TAC MAC CE command has not been performed. The user equipment (501) may further update the timing advance value based on a received TAC MAC CE command. Some of the example embodiments presented herein are directed towards a base station, and corresponding method therein, for uplink timing alignment. The base station (401) may be configured to estimate a proximity of the user equipment (501) to an uplink receive or an uplink cell size of the user equipment. The base station may determine a TAC MAC CE based on the estimation and send the TAC MAC CE to the user equipment (501) for uplink timing alignment.

Abstract: A method in a user equipment (121) for adjusting a transmit timing of uplink transmissions to a network node (110) in a telecommunications system (100) is provided. The user equipment (121) is configurable with more than one aggregated serving cells. The more than one aggregated serving cells are divided into one or more groups of serving cells based on a timing advance value of each of the aggregated serving cells. The one or more groups of serving cells each comprises a timing reference serving cell. The reception timing of a downlink transmission from a timing reference serving cell is used as a timing reference for the transmit timing of uplink transmissions for the serving cells in the group of serving cells comprising the timing reference serving cell, respectively.

Abstract: In a method for assigning serving cells of a mobile terminal to timing advance groups, a network node transmits a Medium Access Control (MAC) control element to a mobile terminal in a wireless communication network. The MAC control element includes a set of first indicators, with each first indicator specifying whether a corresponding serving cell of the mobile terminal is to be included in a timing advance group. The MAC control element also includes at least one second indicator, with each second indicator specifying a timing advance group, and also specifying, via a defined mapping, the serving cell of the mobile terminal to which the timing advance group corresponds.
