摘要： 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.

摘要： 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.

摘要： A communication terminal is capable of simultaneously communicating through a plurality of carriers by carrier aggregation, and the communication terminal comprises: a quality measurement unit for measuring the reception quality of a radio wave transmitted through a plurality of carriers from a base station of a connected cell to obtain a measured value; a primary carrier storage unit storing information specifying a primary carrier chosen from the plurality of carriers; a comparator for comparing a measured value of the primary carrier measured by the quality measurement unit to a threshold value; and a cell search unit for searching for another cell when the measured value of the primary carrier is less than or equal to the threshold value. Consequently, a search threshold value for carrier aggregation can be appropriately determined to perform a cell search and a quality measurement.
