  • Patent number: 10271285
    Abstract: A wireless telecommunication system includes base stations for communicating with terminal devices. One or more base stations support a power boost operating mode in which a base station's available transmission power is concentrated in a subset of its available transmission resources to provide enhanced transmission powers as compared to transmission powers on these transmission resources when the base station is not operating in the power boost mode. A base station establishes an extent to which one or more base stations in the wireless telecommunications system supporting the power boost operating mode conveys an indication of this to a terminal device. The terminal device receives the indication and uses the corresponding information to control its acquisition of a base station of the wireless telecommunication system, for example by taking account of which base stations support power boosting and/or when power boosting is supported during a cell attach procedure.

In a mobile communication system according to the present invention, each of plural radio base stations (eNB#1, eNB#2) reduces, upon detecting that the mobile station (UE) is performing transmission at a maximum transmission power (PCMAX, c), by a predetermined amount a transmission power of the mobile station (UE) in a cell (#1/#2A to #2C) under the control thereof and notifies other radio base station (eNB) of the predetermined amount.

  • Patent number: 9813966
    Abstract: A first wireless device is served with an access node. The access node has a first coverage area. A second wireless device is served with a sub-cell access node. The sub-cell access node has a second coverage area that is contained within the access node coverage area. Based on the determination to reduce the load on the sub-cell access node, a handover of a wireless device from the sub-cell access node to the access node is caused by reducing the transmit power used by the sub-cell access node. Based on a comparison of a first signal quality indicator associated with a first sub-cell access node to a second signal quality indicator associated with a second sub-cell access node, a transmit power from the first access node is reduced.

  • Patent number: 9750007
    Abstract: A device receives information regarding allocation of an enhanced dedicated channel radio network temporary identifier (E-RNTI) to user equipment in a cell forward access channel (Cell_FACH) state, and receives information regarding a state change associated with the user equipment. The device determines that the E-RNTI can be released based on the state change, and provides, to another device, a request to release the E-RNTI in response to the state change and so that the E-RNTI can be used by other user equipment.

  • Patent number: 9705941
    Abstract: A softphone application is provided that facilitates device switching between devices twinned therewith. In an aspect, a first device employing the softphone application generates a request to switch a media session between a second device and a third device to be between the first device and the third device and the softphone application sends, the request to an application server device associated with a cellular service provider identity. The request comprises a first identifier for the first device, a second identifier for the second device, and a device switch indicator. The request is configured to initiate a switch of the media session to being between the first device and the third device based on a determination that the first device and the second device are associated with a common mobile subscriber identity registered for an account associated with the cellular service provider identity.

  • Patent number: 9705657
    Abstract: A method and apparatus for scheduling in a wireless communication system configured for coordinated scheduling are disclosed. The scheduling apparatus sets a gain to be obtained when a terminal performs coordinated scheduling in a neighboring cell. The scheduling apparatus determines whether the terminal in the neighboring cell has moved between a first region where coordinated scheduling is not performed and a second region where coordinated scheduling is performed. Next, if it is determined that the terminal in the neighboring cell has moved between the first region where coordinated scheduling is not performed and the second region where coordinated scheduling is performed, the scheduling apparatus controls the radio unit in the neighboring cell to set an Modulation and Coding Scheme (MCS) level based on the gain and perform scheduling based on the MCS level.

    Abstract: Described embodiments provide controlling signal transmission in a plurality of radio units. The plurality of radio units may be coupled to a digital unit. The digital unit may be spatially separated from the plurality of radio units. Signal quality measurements may be received from multiple radio units when a user equipment is located within an overlapping service area of the multiple radio units. Determination may be made as to whether to simultaneously use at least two of the multiple radio units to transmit a data signal to the user equipment based on the received signal quality measurements. At least two of the multiple radio units may be controlled to transmit a same data signal to the user equipment using a same channel based on the determination result.
