摘要:
In an MBMS service desired to be received, if a condition for performing an MBMS request (an MBMS request trigger criterion) is satisfied (S3: YES), a mobile station 20a in an idle mode (RRC_IDLE) enters an MBMS request transmission process, transmits a preamble to a base station 10b, receives a random access response including scheduling information for transmitting a Message 3 and the like from the base station 10b, and transmits the Message 3 including an RRC Connection Request (including an NAS ID of the mobile station itself), the MBMS request and channel quality information to the base station 10b (S4), and if an Message 4, which includes RRC Connection Setup that is destined for the mobile station itself and includes the NAS ID, and which includes feedback resource assignment information, is received from the base station 10b (S5: YES), the mobile station 20a transits to a connected mode (RRC_CONNECTED), and also uses the designated resource to provide feedback to the base station (S6). Thereby, the MBMS service can be efficiently provided via SCPTM transmission.

Provided are a communication system, a base station apparatus, a mobile station apparatus, and a communication method which can effectively manage measurement information held by a base station apparatus and a mobile station apparatus in a system comprising a plurality of component carriers. The mobile station apparatus is used in a mobile communication system configured by a base station apparatus and a mobile station apparatus. For a plurality of cells with the cell having different frequency, a reference cell with respect to an object to be measured is defined as a measurement reference cell when executing a measurement. The mobile station apparatus specifies one or more of the measurement reference cell for the object to be measured and executes a measurement of the object to be measured for the specified one or more of the measurement reference cell.

A mobile communication system includes a mobile station device and a base station device. The mobile station device has multiple modes concerning a gap section control in a state of being wirelessly connected to the base station device and includes a feedback-period setting unit that sets a feedback period for notifying the base station device of information concerning a downlink channel quality indication in each of the modes based on downlink-data requirement conditions. The base station device includes a resource-allocation-period setting unit that sets an uplink resource allocation period for feedback of the downlink channel quality indication in each of the modes or a downlink resource allocation period based on the downlink-data requirement conditions.
摘要:
A folding portable terminal which can be changed into a desired shape depending on applications of functions such as a telephone, a digital camera, and the like. A folding portable terminal (1) comprises a case (10) with a display section (11) and a case (20) with an operating section (21), and the cases are foldably linked through a hinge mechanism. The hinge mechanism comprises a first hinge section (12) formed by providing a first rotation axis at substantially the center of the case (10) that can be rotated about the first rotation axis in the folding or opening direction relative to the case (20); a second hinge section (24) formed by providing a second rotation axis at substantially the upper end part of the case (20) so as to be parallel to the first rotation axis, the case (20) being rotated in the folding or opening direction relative to the case (10); and means (13a) for linking both ends of the first rotation axis and both ends of the second rotation axis. The hinge mechanism enables the display section (11) and the operating section (21) to be folded without being faced each other, and a user can operate the operating section (21) or view the display section (11) in the folded state.

Provided are a communication system, a base station apparatus, a mobile station apparatus, and corresponding communication methods. A mobile station apparatus (200) comprises: wireless circuitry (203) configured to: communicate with a base station apparatus by carrier aggregation using a plurality of serving cells, wherein a carrier frequency of a serving cell of the plurality of serving cells is different from a carrier frequency of another serving cell of the plurality of serving cells, and receive, from the base station apparatus, a measurement configuration which includes a reporting configuration, a measurement object and a measurement identity which links the measurement object to the reporting configuration, wherein the measurement object indicates a carrier frequency corresponding to a measurement; and radio resource control circuitry (209) configured to perform the measurement, wherein in case that an entry condition of the event corresponding with an event identity of the reporting configuration is fulfilled, the wireless circuitry is configured to transmit, to the base station apparatus, a measurement report which includes measurement results of all of the serving cells.
摘要:
The present invention is to enable reduction of constraint brought by generation of ID codes of reference signals to be used for cooperative reception and the allocation of the reference signals when radio communication is carried out between a plurality of base station apparatuses and a terminal unit. Terminal units UE201 to UE205 are terminal units existing in the cellular zone of a base station apparatus BS200 and are performing communication with base station apparatus UE200. When terminal unit UE201 is located at the edge of cell and its reception characteristic degrades, another base station apparatus, specifically, base station apparatus BS100 also performs cooperative transmission while terminal unit UE201 performs cooperative reception. In this case, in order to demodulate the signal from base station apparatus BS100, an ID code of a reference signal that is different from the reference signal the terminal unit uses to demodulate the signal from a solo base station apparatus is used as the ID code of the reference signal that is transmitted from base station apparatus BS100 and specific to the terminal unit.
