  • Patent number: 11297562
    Abstract: Aspects of the present disclosure relate to a method in a terminal configured to receive transmissions from a telecommunications network. The method comprises receiving a transmission on an anchor carrier, the transmission including control information. The method comprises receiving, on the anchor carrier, an allocation of a non-anchor carrier for receiving data, wherein the non-anchor carrier has a frequency. The method comprises performing a cell search operation, comprising scanning a plurality of frequencies for a cell of the telecommunications network, and inhibiting the frequency of the non-anchor carrier in the scanning.

  • Patent number: 10805978
    Abstract: A system, device and methodology for releasing a connection between user equipment (UE) and a node in a communications network is disclosed. The method includes, at the UE, responsive to an application layer indication that no further data is expected by the UE, receiving a RRC connection release message from the node and transmitting, from the UE, a radio link control (RLC) status message using RLC acknowledged mode (AM) to the node. An early connection release timer at the UE and node based on RLC AM parameters for a signal radio bearer (SRB) is started and upon expiry of the early connection release timer, the node releases the RRC connection. This obviates the need to wait a full 10 s per the 3GPP standard to release the connection during periods of poor radio connectivity, and reduces power consumption at the UE.

  • Patent number: 9445337
    Abstract: In accordance with one embodiment, there is provided a method for use by a wireless cellular telecommunications device camped on a first cell. The method comprises, at the device: selecting a parameter applicable to a priority-based re-selection algorithm and also applicable to another cell; measuring an attribute of a signal received from a second cell; and, evaluating the second cell for re-selection according to a ranking algorithm based at least on the selected parameter and the measured attribute. A device and computer readable medium are also provided.

  • Patent number: 9060314
    Abstract: A wireless cellular telecommunications device stores a first parameter obtained from system information of a first cell and measures an attribute of a signal received from a candidate cell, determines if the candidate cell is a closed subscriber group cell, and evaluates the candidate cell for re-selection. If the candidate cell is determined to be a closed subscriber group cell, the evaluation of the candidate cell for re-selection is based on at least the measured attribute irrespective of the first stored parameter, that first stored parameter indicating a minimum value for the measured attribute.

  • Patent number: 9049657
    Abstract: A user equipment and a method performed by the user equipment is provided. The method comprises receiving a network message from a network, inhibiting a sending of a user equipment message to the network and transitioning to a target state. The user equipment is adaptable/adapted and/or configurable/configured to receive a network message from a network, inhibit a sending of a user equipment message to the network and transition to a target state. The network message indicates the target state to which the user equipment is to transition.

  • Patent number: 9014688
    Abstract: A user equipment (UE), comprising at least one component configured to support a handover during decreasing radio conditions, wherein an event is triggered using at least one of a time to trigger for rapid degradation or radio conditions (TTTrd) value and a filter coefficient for rapid degradation of radio conditions (FCrd) value that are different than the corresponding standard values indicated by a network. Also included is a UE, comprising at least one component configured to support a method comprising obtaining cell measurements using network indicated standard parameters and parameters configured for rapid degradation of radio conditions, monitoring radio conditions, and evaluating an event using the parameters configured for rapid degradation of radio conditions if rapid degradation of radio conditions is detected, or using the network indicated standard parameters otherwise.
