  • Systems and methods for controlling cell selection in a heterogeneous cellular network based on primary direction of traffic flow
    Patent number: 9288733
    Abstract: Systems and methods are disclosed for controlling cell selection between a high power base station and a neighboring low power base station in a cellular network. In one embodiment, a primary direction of traffic flow for a user equipment located within a transition zone between a high power base station cell of the high power base station and a low power base station cell of the low power base station is determined to be either an uplink direction or a downlink direction. Cell selection for the user equipment is then controlled based on the primary direction of traffic flow for the user equipment such that selection of the high power base station cell is favored if the primary direction of traffic flow is the downlink direction and selection of the low power base station cell is favored if the primary direction of traffic flow is the uplink direction.

  • Inter-rat systems access network (AN) load balance and congestion control mechanism
    Patent number: 9288717
    Abstract: A system and method to perform load-balancing and congestion control between a primary Radio Access Technology (RAT) and a secondary RAT. A broadcast message is sent to all User Equipments (UEs) operating under the secondary RAT. If the primary RAT is congested, a congestion indicator in the broadcast message prevents the UEs from idle re-selecting or switching to the primary RAT. Even if the primary RAT is not congested, the broadcast message may still include other parameters such as one or more probability values, a group identifier for the UE groups, and a retention timer. The idle UEs in the secondary RAT that generate device-specific random values that are equal to or greater than the applicable probability threshold value(s) are allowed to reselect the primary RAT. If an idle UE fails this probability test, it may not be allowed to reselect the primary RAT again until the retention timer expires.

  • Method and arrangement for uplink power control
    Patent number: 9288766
    Abstract: The disclosure relates to methods and devices for performing uplink power control in a radio communication system. An example method comprises a step of receiving, at a user equipment (UE) a transmit power control (TPC) command. The method also comprises, if the UE does not have an uplink transmission scheduled for a subframe associated with the TPC command, a step of accumulating, by the UE, the TPC command with previously received TPC commands based on whether the UE has reached a maximum transmit power or a minimum transmit power in a reference format for a Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS) or Physical Uplink Control Channel (PUCCH) transmission. Thus the UE is enabled to receive TPC commands while the UE is not transmitting anything in the uplink.

  • Antenna Port Detection
    Publication number: 20160072598
    Abstract: There is provided presence detection of a second transmit antenna port in a distributed antenna port system. Cell-specific reference signals, CRS, are received on a first receive antenna port and a second receive antenna port. The CRS have been transmitted by a first transmit antenna port and a second transmit antenna port in the distributed antenna port system. Reference signal received power, RSRP, measurements and reference signal resource element received power, RSRERP, measurements are estimated from the CRS. Presence is detected by comparing each one of at least one metric based on filtered RSRP measurements and filtered RSRERP measurements to a respective threshold.

  • Systems and Methods For Selecting a Network Access System
    Publication number: 20160073325
    Abstract: A system according to some embodiments of the invention includes (1) a component (e.g. ANDSF) that provides a cell selection rule to a UE and (2) a component (e.g. an access node) that provides the UE with information about the load in the cell currently utilized by the UE. This enables the UE to determine whether to leave the cell, which may be a 3GPP cell, and use a different cell, which may be a non-3GPP cell, by applying the cell selection rule in conjunction with its knowledge about the load of the cell.

    Abstract: A handover control method and apparatus for limiting handover of a User Equipment (UE) from a macrocell to an underlying small cell when the UE is operating in a High Speed Mobility (HSM) mode in a radio access network. The UE receives an HSM pilot strength threshold offset parameter from the network and initiates handover from a macrocell to an underlying small cell using a first pilot strength threshold value when the UE is operating in a standard mode. The UE initiates the handover using a second pilot strength threshold value when the UE is operating in HSM mode. The second pilot strength threshold value is equal to the first pilot strength threshold value modified by the HSM pilot strength threshold offset parameter.
