  • Patent number: 11540161
    Abstract: In a wireless communication terminal in a wireless communication system for performing a control not to transmit signals, or to transmit signals with a reduction in a transmission power by a part of radio resources for a downlink signal in a cell provided by a base station, the terminal receives control information in generating a report related to a measurement result of the cell provided by the base station, monitors a state of a radio link with an own cell, and performs measurement on reception of the downlink signal. If an instruction for restricting the measurement to a part of the radio resources is included in the control information from the base station after the radio link failure occurs, the terminal generates and transmits a radio link failure report including the measurement result in the radio resources as instructed when the radio link failure occurs.

  • Publication number: 20220408372
    Abstract: The invention relates to methods for adjusting the transmit power utilized by a mobile terminal for uplink transmissions, and to methods for adjusting the transmit power used by a mobile terminal for one or more RACH procedures. The invention is also providing apparatus and system for performing these methods, and computer readable media the instructions of which cause the apparatus and system to perform the methods described herein. In order to allow for adjusting the transmit power of uplink transmissions on uplink component carriers, the invention suggests introducing a power scaling for uplink PRACH transmissions performing RACH procedures on an uplink component carrier. The power scaling is proposed on the basis of a prioritization among multiple uplink transmissions or on the basis of the uplink component carriers on which RACH procedures are performed.

  • Patent number: 11405831
    Abstract: When a handover request for performing a handover of a terminal (70) from a macro cell C1 to a CSG cell C2 is received from an SeNB 10 (S8), a base station (TeNB) (40) of the CSG cell C2 transmits a handover response in accordance with a handover enabled/disabled state (S12). The handover response includes an identifier of the terminal (70) in the CSG cell C2. Upon receiving the response, the SeNB (10) notifies the identifier to the terminal (70) (S14). The TeNB (40) repeatedly transmits a dedicated signal containing a handover command via a dedicated channel set using the identifier at an interval shorter than a gap period (S18). Accordingly, whether or not access is permitted can be judged promptly and a smooth handover can be realized.

  • Patent number: 11388635
    Abstract: When detecting occurrence of an event for transmitting a measurement report of a radio condition of a cell at a frequency set for a base station apparatus, to the base station apparatus (3) communicating with a terminal apparatus (2), the terminal apparatus (2) in a wireless communication system (1) creates a measurement report including information indicating radio conditions of cells at a frequency at which the event occurred and at another different frequency. The base station apparatus (3) controls whether or not to perform handover of the terminal apparatus (2) to another cell, on the basis of the measurement report transmitted from the terminal apparatus (2). Thereby, there is provided a wireless communication system in which a base station apparatus and the terminal apparatus are communicable with each other using multiple frequencies, the wireless communication system being capable of shortening time required for handover.

  • Publication number: 20220070880
    Abstract: The invention relates to methods for improving a scheduling request transmission between a UE and a base station. The transmission of the scheduling request is postponed, by implementing a threshold that the data in the transmission buffer has to reach, before a transmission of the scheduling request is triggered. In one variant, the data in the transmission buffer needs to reach a specific amount, to trigger a scheduling request. The invention refers to further improvements: the PDDCH monitoring time window is delayed after sending a scheduling request; the dedicated scheduling request resources of the PUCCH are prioritized differently such that low-priority scheduling requests are transmitted less often.
