摘要:
To maintain communications of uplink ACK/NACK signals even for a transition period during which the number of aggregated component carriers is added/removed by higher layer signaling, it is a feature providing a reception section that receives the PDSCH for each of CCs that constitute the system band, a demodulation section (406) that demodulates the received PDSCH of each of CCs, an ACK/NACK signal generating section (418) that generates an uplink ACK/NACK signal in response to a demodulation result of the PDSCH in the demodulation section (406), and a mapping section (415) that allocates radio resources to an uplink ACK/NACK signal of the anchor block using LTE, while allocating user-specific radio resources to uplink ACK/NACK signals of the other CCs.

A rectangular tubular terminal connecting portion (11) includes two side plates (17) standing up from opposite sides of a base plate (15) via curved portions (16). A resilient contact piece (20) includes a substantially arcuate turned portion (21) extending forward from a front end (15F) of the base plate (15) and a main portion (22) extending back from an extending end of the turned portion (21). First slits (24) extend back from a front end (11F) of the terminal connecting portion (11) along lateral edges (21S) of the turned portion (21), second slits (25) extend from the rear ends of the first slits (24) along the front ends (15F, 16F) of the base plate (15) and the curved portions (16), and protecting plates (26) defined by the first and second slits (24, 25) are cantilevered toward the turned portion (21).

摘要:
A housing (10) is formed with jig insertion holes (20) penetrating through an outer wall (19) located at a side of deformation spaces (17) opposite to locking lances (14). Deformation restrictions (42) of a front retainer (40) are formed with guides (49) that are cut out to allow an unlocking jig inserted through the jig insertion hole (20) to reach the locking lance (14) when the front retainer (40) is at a retracted position and to position the unlocking jig in a width direction crossing both a resiliently deforming direction of the locking lances (14) and an inserting direction of terminal fittings (30) into cavities (13).
摘要:
A restriction (30) is provided for preventing a second housing (20) from being fit in an incorrect oblique posture into a receptacle (12). The restriction includes restricting ribs (31) projecting from an inner surface of the receptacle (12) and restricting grooves (32) formed by recessing an outer surface of the second housing (20). Each restricting rib (31) includes a first rib (31A) extending in a connecting direction and second ribs (31B) located behind the front end of the first rib (31A) in the connecting direction. Each restricting groove (32) includes a first groove (32A) extending in the connecting direction and second grooves (32B) located before the rear end of the first groove (32A) in the connecting direction.
摘要:
A connector has a housing (12) and a frame (15). The housing (12) has a wall (58) and a lock (19) that is resiliently deformable outward in the thickness direction of the wall (58). The lock (19) engages an interlocking portion (18) in the frame (15) when the housing (12) and the frame (15) are connected properly. A bracket (16) is inserted into a deformation area (62) for the lock (19) to prevent deformation of the lock (19). Thus, the lock (19) remains engaged with the interlocking portion (18) even if a force acts in a direction to separate the housing (12) and the frame (15).

The present invention is designed to provide a radio base station apparatus, a mobile terminal apparatus, a radio communication system and a radio communication method which can cope with an increased number of users. A radio base station apparatus is provided with: a signal generating section that generates a first downlink control signal and a second downlink control signal for a mobile terminal apparatus; a first multiplexing section that multiplexes the first downlink control signal on a control region up to a predetermined number of symbols from the top of a subframe; a second multiplexing section that frequency-division-multiplexes the second downlink control signal on radio resources from the next symbol in the control region to the last symbol of the subframe; and a transmission section that transmits the first downlink control signal multiplexed on the control region and the second downlink control signal multiplexed on the radio resources.

In order to report aperiodic channel state information (A-CSI) flexibly even when a user terminal performs radio communication using a plurality of component carriers (CCs) in an HetNet environment, the present invention provides an aperiodic channel sate information reporting method comprising: a step of transmitting in advance, from a pico base station (PeNB) to pico UE, channel state measurement target information having information about presence or absence of reporting of channel state information and a subframe as a measurement target associated with trigger bit information indicating information about presence or absence of reporting of channel state information and a component carrier as a measurement target (step ST401); and a step of reporting channel state information of the subframe and the component carrier designated by the trigger bit information transmitted on a PDCCH, to the pico base station (PeNB) on a PUSCH (step ST406).
