  • Patent number: 10298463
    Abstract: A communication network includes nodes. The nodes are capable of communicating over a current generation network, which will include 5G before long. One, some, or all of the nodes are also capable of communicating over a previous generation network, to which 4G will be relegated before long. A third node receives a first signal from a first node over the current generation network, a second signal that is a retransmission of the first signal from a second node over the current generation network, and network dimensional parameters from the first node and/or the second node over the previous generation network. The network dimensional parameters enable the third node to determine precise locations of the first node and the second node. Using a function of the network dimensional parameters, the third node can correlate the first signal and the second signal and generate a simplified signal therefrom.

  • Patent number: 10278124
    Abstract: Methods and systems are provided for calculating a bias value based on radio frequency signal power measurements. A wireless communication device (WCD) measures the powers of radio frequency signals received by the WCD, including a first radio frequency signal transmitted by a first base station of a wireless network and a second radio frequency signal transmitted by a second base station of the wireless network. The first base station transmits radio frequency signals at a higher power than the second base station. The WCD calculates a bias value based on at least one of the measured powers of the first radio frequency signal and the second radio frequency signal. The bias value, in combination with the measured powers of the first and second radio frequency signals, can be used to select one of the first and second base stations.

  • Patent number: 9854496
    Abstract: A novel and efficient connected mode cell reselection procedure is proposed to improve the mobility performance for user equipments (UEs) configured with extended connected mode Discontinuous Reception (DRX) cycle in LTE systems. A UE-centric mobility mechanism with which a UE performs cell reselection in RRC connected mode is proposed. The UE is allowed to select a target cell without handover signaling in the source cell and when needed to initiate signaling with the target cell, for which signal quality is much better. In this way, handover failures due to failed signaling in the source cell can be avoided. More specifically, the proposed mobility mechanism reduces signaling overhead and is inherently robust towards different DRX cycle settings, i.e., longer DRX cycles do not cause more failures, or more overhead, or more battery consumption.

One of the cooperating nodes is a base station being associated with a UE group comprising UEs having correlated mobility related parameters. The method in the base station comprises receiving, from a first UE in the UE group, a mobility related parameter associated with the first UE. The method further comprises determining whether to initiate a mobility related procedure for a second UE in the UE group based on the received mobility related parameter; and further comprises initiating the mobility related procedure for the second UE when it is determined that the mobility related procedure is to be performed. Thereby, prediction and decisions related to mobility events, e.g. handover events, for the second UE or for the whole group may be performed e.g.

  • Patent number: 9554313
    Abstract: Cell relocation procedures to address handover between a macro radio network controller (RNC) and a home base station in a wireless communication network, while accounting for access control or membership verification procedures needed to support a Closed Subscriber Group (CSG) at the home base station. An example method begins with the receiving of a request for handover of the mobile terminal from an RNC of the macro wireless network. A closed subscriber group (CSG) identifier for the home base station and a cell access mode for the home base station are then sent, to a core network node associated with the macro wireless network, for use by the core network node in membership verification or access control for the mobile terminal. In response, the home base station receives a CSG membership status for the mobile terminal from the core network node.

    Abstract: A femto cell neighbor list message for a wireless communication system that includes the frequencies and pseudonoise offsets reserved for macro cells and femto cells is disclosed. When the user equipment discovers the femto cell, the user equipment can read the Femto Cell Identification Message and present the identification information to the subscriber. In absence of this knowledge, a manual femto cell search must search all frequencies and all pseudonoise offsets resulting in lengthy search times.

  • Patent number: 9503989
    Abstract: A method and apparatus for power control for wireless transmissions on multiple component carriers corresponding to multiple serving cells associated with multiple timing advances are disclosed. A wireless transmit/receive unit (WTRU) may determine transmit powers for a first physical channel for a first serving cell in a first timing advanced group (TAG) and a second physical channel for a second serving cell in a second TAG. The first TAG may less timing advanced than the second TAG. The WTRU may determine a WTRU configured maximum output power (PCMAX) for an overlapping portion, which may be a portion of a transmission of the first channel in a first subframe that overlaps in time with a portion of a transmission of the second channel in a next subframe. The WTRU may adjust the channels such that a sum of their transmit powers in the overlapping portion does not exceed the determined PCMAX.
