20140023010 | EFFICIENT EXTENDED POWER HEADROOM REPORTING FOR SEMI-PERSISTENT SCHEDULING - The invention relates to a method for transmitting power headroom information from a user equipment to the base station. The transmission is made dependent on scheduling type of the uplink resource, for which the power headroom information is to be calculated and over which it is to be transmitted. If the uplink resource is dynamically scheduled, then the extended power headroom report according to Rel. 10 is transmitted; if it is scheduled persistently, e.g. as part of a semi-persistent scheduling configuration, then a basic power headroom report according to Rel. 8/9 is transmitted. The invention circumvents the problem of delaying data in persistently allocated uplink resources when transmitting an extended power headroom report. | 01-23-2014 |
20140029586 | PROPAGATION DELAY DIFFERENCE REPORTING FOR MULTIPLE COMPONENT CARRIERS - 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. | 01-30-2014 |
20140307674 | BUFFER STATUS REPORTING IN A MOBILE COMMUNICATION SYSTEM - The 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. | 10-16-2014 |
20140307681 | POWER-LIMIT REPORTING IN A COMMUNICATION SYSTEM USING CARRIER AGGREGATION - 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. | 10-16-2014 |
20140348045 | COMMUNICATION TERMINAL AND METHOD FOR USE IN A COMMUNICATION TERMINAL - The present invention describes a method for configuring a measurement report type to be used by a receiver to report a measurement to a transmitter, wherein the measurement is reported to the transmitter in a report signal over a control channel. The method includes selecting a first measurement report type and at least one second measurement report type to be used by the receiver to report the measurement, generating a measurement reporting pattern defining an occurrence of the first measurement report type and the at least one second measurement report type in the report signal transmitted by the receiver to the transmitter over control channel, and notifying the first measurement report type, the at least one second measurement report type, and the generated measurement reporting pattern to the receiver. | 11-27-2014 |
20140362722 | COMPONENT CARRIER ACTIVATION AND DEACTIVATION USING RESOURCE ASSIGNMENTS - 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. This indication is for example implemented by means of a bit-mask that indicates which of the configured uplink component carriers are to be activated respectively deactivated. | 12-11-2014 |
20150049705 | COEXISTENCE INTERFERENCE REPORTING MECHANISM - The invention relates methods for interference reporting by a mobile terminal in a mobile communication system. The invention is also providing apparatus for performing these methods, and computer readable media the instructions of which cause the apparatus to perform the methods described herein. In order to allow for interference reporting, the mobile terminal detects an interference condition between the communication with the base station via the first resource and a communication with the wireless communication device via the second resource, reports on the interference condition to the base station; receives reconfiguration information indicating a third resource and reconfigures the communication with the base station to the third resource. Further, the mobile terminal detects whether or not the interference condition persists for potential communications with the base station via the first resource, and, in case the interference condition has been re(optional) solved, reports on an interference resolution to the base station. | 02-19-2015 |
