  • Patent number: 10117193
    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.

  • Publication number: 20180254879
    Abstract: This invention relates to a proposal of an uplink resource assignment format and a downlink resource assignment format. Furthermore, the invention relates to the use of the new uplink/downlink resource assignments in methods for (de)activation of downlink component carrier(s) configured for a mobile terminal, a base station and a mobile terminal. To enable efficient and robust (de)activation of component carriers, while minimizing the signaling overhead, the invention proposes a new uplink/downlink resource assignment format that allow the activation/deactivation of individual downlink component carriers configured for a mobile. The new uplink or downlink resource assignment comprises an indication of the activation state of the configured downlink component carriers, i.e., indicate which downlink component carrier(s) is/are to be activated or deactivated.

  • Publication number: 20180249531
    Abstract: The disclosure relates to methods for improving the DRX operation of a UE by introducing an additional DRX wake-up cycle, which runs in parallel to the short and/or long DRX cycle. The DRX wake-up cycle defines time intervals after which the UE starts monitoring the PDCCH for a wake-up duration of time; the UE does not perform any other operation during the wake-up duration apart from monitoring the PDCCH. The time intervals of the wake-up cycle between the wake-up durations are preferably shorter than the one of the DRX long cycle, and may have the same or a shorter length than the ones of the DRX short cycle. The wake-up duration may be as long as the on-duration of the DRX short/long cycle, or may be preferably much shorter, such as only one or a few subframes.

  • Publication number: 20180077600
    Abstract: An invention relates to methods for transmitting a buffer status report (BSR) in a mobile communication system, more particularly to the definition of rules for triggering, generating and transmitting BSRs. The invention also relates to a data transmission method utilizing new rules to decide data of which radio bearers is transmitted within a given transmission time interval. Moreover, the invention relates to scheduling method for radio resources that is taking into account additional scheduling-relevant information from the buffer status reporting and/or data transmission method. To avoid unnecessary grants from the network and to suggest an advanced handling of data transmissions the invention suggests a buffer status reporting and data transmission schemes that take into account the scheduling mode of data of radio bearers pending for transmission to decide whether to report on it in a buffer status report, respectively, whether to multiplex the data to a transport block for transmission.

  • Publication number: 20180007642
    Abstract: The invention relates to methods for informing an eNodeB on the transmit power status of a user equipment in a mobile communication system using component carrier (CC) aggregation. Furthermore, the invention is also related to the implementation of these methods by hardware and their implementation in software. The invention proposes procedures that allow the eNodeB to recognize the power usage status of a UE in a communication system using carrier aggregation. The UE indicates to the eNodeB, when the UE is close to using its total maximum UE transmit power or when it has exceeded same. This is achieved by the UE including indicator(s) and/or new MAC CEs to one or more protocol data units transmitted on respective component carriers within a single sub-frame that is providing the eNodeB with power status information. The MAC CEs may report a per-UE power headroom. Alternatively, the MAC CEs may report per-CC power headrooms and/or power reductions applied to the respective uplink CCs.

  • Publication number: 20170295590
    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.

  • Patent number: 9756594
    Abstract: The invention relates to methods for reporting on downlink timings by a mobile terminal in a mobile communication system. In order to allow for an aggregation access point to obtain information on propagation delay differences of downlink transmissions on aggregated serving cells, the invention suggests the mobile terminal to report timing information based on reception time difference information for a the target/reference cell. The mobile terminal performs measurements relating to transmission and/or reception time differences on the target/reference cell, and reports same to the eNodeB. The eNodeB compares the measurement result to a predefined maximum propagation delay time difference. Alternatively, the mobile terminal performs the measurements, compares same to the predefined maximum propagation delay time difference and then report the comparison result to the eNodeB.

  • Patent number: 9749927
    Abstract: The invention relates methods for time aligning uplink transmissions by a mobile terminal in a mobile communication system, and to methods for performing a handover of a mobile terminal to a target aggregation access point. 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 aligning the timing of uplink transmissions on uplink component carriers, where different propagation delays are imposed on the transmissions on the uplink component carriers, the inventions suggests to time align the uplink component carriers based on a reference time alignment of a reference cell and a reception time difference or propagation delay difference between the downlink transmissions in the reference cell and the other radio cells, the uplink component carriers of which need to be time aligned.

  • Patent number: 9655160
    Abstract: The invention relates to methods for avoiding in-device coexistence (IDC) interference in a mobile terminal in a mobile communication system, apparatus for performing these methods, and computer readable media instructions to cause the apparatus to perform the methods. In order to avoid IDC interference, an IDC interference indication is reported for at least one of a first cell and a second cell on which an interference condition is detected. In response, an activation/deactivation pattern is received for at least one of the first and second cells for which the interference condition is detected. The activation/deactivation pattern indicates an off-duration and an offset specifying a time-period during which communication via the at least one of the first and second cells is to be deactivated.
