A user equipment including: a transmission unit that transmits a signal to a base station apparatus using a preconfigured uplink resource; a reception unit that receives a signal from the base station apparatus; and a control unit that starts or restarts a predetermined timer in response to receiving the signal from the base station apparatus.

User equipment, base station apparatus and communication method

A user equipment includes a control unit that sets an operation mode of the user equipment to an idle mode; and a transmission unit that transmits, while a time alignment retained by the control unit is valid, information indicating presence of the user equipment on each of transmission resources with a predetermined frequency in a time direction, from among a plurality of transmission resources that is preconfigured for transmitting data in the idle mode and arranged in the time direction, wherein the transmission unit stops transmitting the information indicating the presence of the user equipment in response detecting that the time alignment is invalid.

User equipment, base station and communication method

A terminal includes a receiving unit that receives information indicating whether each condition of one or more conditions for validating a time alignment is activated or deactivated; and a control unit that independently activates or deactivates each condition of the one or more conditions in accordance with the received information.

Terminal, base station, and communication method

A user equipment includes a control unit that sets an operation mode of the user equipment to an idle mode; a transmission unit that transmits data by using a preconfigured radio resource for transmitting data in the idle mode; and a reception unit that receives transmission acknowledgement information for the data by monitoring at least one search space from a paging search space or an additional search space that is to be monitored in the idle mode.

User equipment and communication method

A base station apparatus including: a transmission unit that transmits a first activation signal, which is an activation signal that becomes a trigger for monitoring a paging occasion, for each group of grouped user equipments and transmits a second activation signal, which is a activation signal common to multiple groups, wherein the transmission unit transmits, to the user equipment, information instructing whether to perform monitoring of the second activation signal or information indirectly instructing whether to perform monitoring of the second activation signal.

Base station apparatus and user equipment

A communication device used as a first communication device in a wireless communication system including the first communication device, a second communication device communicating with the first communication device, and a user equipment communicating with the first communication device, includes an acquisition unit configured to acquire a parameter used for performing a random access procedure from the second communication device; and a control unit configured to transmit, in the case of receiving a random access preamble from the user equipment in a random access channel indicated by the parameter, information indicating that the random access preamble indicated by the parameter is received from the user equipment to the second communication device.

Communication device and random access control method

An interface method between a central-aggregate apparatus and an extension apparatus is provided, which includes: transmitting, by the central-aggregate apparatus, uplink signal indication information for a user equipment and an identifier of the user equipment to the extension apparatus; retaining, by the extension apparatus, the identifier and uplink signal information extracted from the received uplink signal indication information and transmitting an uplink signal indication to the user equipment; receiving an uplink signal transmitted from the user equipment based on one or both of the retained uplink signal information and identifier; extracting data information from the uplink signal, estimating uplink communication quality based on the uplink signal, and transmitting one or both of the extracted data information and the estimated uplink communication quality to the central-aggregate apparatus; and receiving, by the central-aggregate apparatus, one or both of the data information and the uplink communication quality from the extension apparatus.

Interface method between central aggregate apparatus and extension apparatus, and radio control system

A radio base station is disclosed including an extension station and a central aggregate station, wherein the extension station includes a processor that determines whether a resource used when a user equipment transmits an uplink reference signal is allocated, a first receiver that receives the uplink reference signal from the user equipment based on a determination result of processor, wherein the processor calculates measurement information based on the uplink reference signal received by the first receiver, and a transmitter that transmits the measurement information calculated by the processor to the central aggregate station, and the central aggregate station includes a receiver that receives the measurement information from the extension station.

Radio base station and measurement information transmission/reception method
