  • Patent number: 10448400
    Abstract: The present disclosure relates to a technique for radio link monitoring in a wireless communication system, and to operation procedures of the base station and user equipment and a method for radio link quality evaluation on the basis of the technique. In the method, the user equipment divides the downlink channel bandwidth into multiple frequency ranges, measures channel states for each frequency range, and evaluates the radio link quality based on channel state measurement results. Thereafter, the user equipment sends frequency range quality information to the base station, which may then utilize the same for downlink resource allocation. Hence, it is possible to solve the problem of the existing scheme wherein the user equipment enters the physical layer problem detection state or the radio link failure state although a frequency range usable for service provisioning is present within the downlink channel bandwidth.

The predetermined timer is a timer configured to define a maximum waiting time from transmission of the connection reestablishment request signal to reception of a connection reestablishment response signal in the mobile station.

  • Patent number: 10091693
    Abstract: The present invention facilitates handoffs for a mobile terminal in a wireless access network that is capable of supporting different types of handoffs. The different handoff types may include soft handoffs and fast base station switching (FBSS). In operation, context information associated with supporting wireless communications between the wireless access network and the mobile terminal are determined. Based on whether the context information is shared between base stations involved in the handoff or transferred from one base station to another of the base stations involved in the handoff, a particular handoff type is selected from the different handoff types that are available. Selecting the specific type of handoff to use may also be based on the level of context information that is available, the actual content of the context information, application preferences, channel conditions, base station or mobile terminal capabilities, or any combination thereof.

  • Patent number: 10050761
    Abstract: Methods that are performed by a user equipment (UE) and corresponding methods of base stations that allow a UE to determine whether the UE is in a carrier aggregation enabled or disabled state. One exemplary embodiment of a method performed by a UE determines a first artificial value for a first parameter and a second artificial value for a power headroom (PHR) for a secondary component carrier (SCC), the first and second artificial values being substantially low relative to a configuration of the network, generates an artificial report including the first and second artificial values, transmits the artificial report to a primary cell providing a primary component carrier (PCC) and receives an indication that the UE is placed in a carrier aggregation disabled state.

  • Patent number: 9974109
    Abstract: A wireless communication system is presented in which user equipment (UE) performs non-intra-frequency (NIF) cell reselection. The NIF cell reselection process can: detect, on a discontinues reception (DRX) cycle, whether a NIF for a second cell has passed a second reselection threshold; perform, on the DRX cycle, additional checks or measurements to determine whether a higher priority NIF for a third cell has passed a third reselection threshold; and continue a cell reselection process for the second cell and the third cell. The NIF cell reselection techniques can help ensure that the UE reselects to higher priority cells without expending an unnecessary amount power.

    Abstract: A method includes establishing a first session (e.g., a Wi-Fi call) via a first connection to a first network, where the connection to the first network is provided by a first receiver of the mobile device, and monitoring a characteristic of the first connection to the first network. The method includes determining whether the characteristic satisfies a threshold. When the characteristic does not satisfy the threshold, the method includes activating a second receiver of the mobile device, establishing a second connection to a second network, and initiating a handover procedure to transfer the first session from the first network to the second network. The second connection to the second network is provided by the second receiver of the mobile device. As a result of the handover procedure, the first session may be merged with or transferred to a second session (e.g., a cellular call) provided via the second network.

  • Patent number: 9900141
    Abstract: A receiving apparatus for SNR estimation of a signal such as the LTE PUCCH, transmitted over a channel of an OFDM wireless communication system. The proposed apparatus brings determines the noise power level in the frequency domain based on a noise covariance matrix where timing errors are back compensated in the equation since timing error is expressed a complex exponential therein. Contrary to the common methods used for determining the noise power level, in the present invention deriving the channel estimate components from the pilot symbol(s) comprised in the received signal is not required. Based on the present invention, user's transmit power is reduced thereby improving battery power longevity. Further, since interference is reduced, more users may be multiplexed together in the same resources. A method and a computer program product are also claimed.
