  • Patent number: 9955484
    Abstract: A mobile radio device uses its own location/position information to itself select a radio access resource from a plurality of radio access resources shared among a plurality of mobile radio devices; and sends a transmission on a wireless shared radio access channel using the selected radio access resource. In non-limiting embodiments: the location/position information represents global/absolute physical position, or a position relative to a local reference location within an access region which may be a cell, building, roadway, etc.; and the radio access resources are time slots; frequency blocks; and/or preambles. The examples have a map or algorithm stored in the device's local memory that associates different access resources to different discrete location areas within the access region; the algorithm identifies the location area that corresponds to the location/position information and outputs the selected access resource (or an index/identifier of it) associated with the identified location area.

  • Publication number: 20170318458
    Abstract: A user equipment (UE) has both cellular and non-cellular links. The network sends it a first indication to maintain using a first set of security keys generated from a parameter specific to a source access node after the UE hands over the cellular link to a target access node without changing a wireless termination (WT) that is connected with the UE via the non-cellular link. The network uses that key to maintain the non-cellular link with the UE after the cellular link handover. From the UE's perspective it uses that key to authenticate its non-cellular link prior to the cellular link handover, but this handover does not change the WT which communicates with the UE via the non-cellular link so the UE can, only in response to receiving a first indication associated with the handover, use that same key to maintain that non-cellular link after the handover.

  • Publication number: 20150072699
    Abstract: The present invention relates to methods and apparatuses for controlling cell configuration in a cellular network, wherein a cell identity and a local cell spectrum resource entity or profile are assigned to an access device in response to a result of sensing a local radio environment at said access device to detect possible neighbor cells. The assigned local cell spectrum resource entity or profile is used to allocate cell spectrum resource from a shared multi-operator spectrum to said access device.

  • Patent number: 8842652
    Abstract: A relay node receives from user equipments UE CQI reports which give a CQI value per radio band resource RBR, from which are aggregated across the RBRs and/or aggregated per UE across that UE's RBR values. The relay node reports an indication of the average to its controlling access node (eNodeB), either explicitly or implicitly (e.g., a gain applied to the CQI of the downlink between the relay and access nodes). The relay node also checks the UEs' buffer status (actual or predicted) and reports either periodically or based on an underflow/overflow occurrence. For periodic reports, each UE buffer experiencing the overrun/underrun is reported.

  • Patent number: 8543064
    Abstract: Uplink interference coupling is estimated between a first cell and a second cell by adjusting downlink interference coupling between the cells at least according to user equipment UE transmit power per physical resource block PRB. This estimated uplink interference coupling is used to decide whether to take a component carrier into use in the first cell. In various embodiments: the uplink interference coupling is estimated by adjusting the downlink interference coupling according to transmit power per PRB of a first UE in the first cell and transmit power per PRB of a second UE in the second cell; and by further adjusting the downlink interference coupling according to path losses of the first and second UEs; and the transmit power per PRB as well as the path loss of the second UE is determined from signaling received in the first cell from the second UE operating in the second cell.

  • Publication number: 20090257356
    Abstract: A method includes making measurements of a received channel, and transmitting a channel quality report that includes at least one resource block-specific report indicative of a value of a channel quality metric over a bandwidth x, and that further includes an additional report indicative of the value of the channel quality metric over a bandwidth y, where y is greater than x. The channel quality metric may be a signal to interference plus noise ratio (SINR), and the additional channel quality report may be indicative of a difference between a mean value of the SINR of physical resource blocks found by a user equipment to exceed a reporting threshold and a mean value of the SINR over the measurement bandwidth y.

  • Publication number: 20080268863
    Abstract: An approach is provided for efficient signaling for reporting of channel quality information. A parameter is set for a silent period associated with reporting of channel quality information. The channel quality information is transmitted by the terminal only during a time instant outside of the silent period. The silent period is a time interval before transmission of the quality information by the terminal to an inactive state from an active state.
