摘要： A method by a user equipment (UE) is described. The method includes instructing a physical layer of the UE to signal a scheduling request (SR) on a Physical Uplink Control Channel (PUCCH) based on whether scheduling request counter is less than the maximum number of scheduling request transmission, and transmitting, to an evolved Node B (eNB), the SR on either of the PUCCH on a primary cell and the PUCCH on a PUCCH secondary cell. The scheduling request counter is incremented in a case that the scheduling request counter is less than the maximum number of scheduling request transmission.

摘要： A communication system comprises a base station that includes circuitry and a mobile station that includes circuitry and which is configured to perform random access to the base station using a preamble. The preamble corresponds to an ID number among a plurality of ID numbers, the number of the plurality of ID numbers is constant, the plurality of ID numbers are contiguous, and the ID number is randomly selectable, by the mobile station, from a set of ID numbers which are included in the plurality of ID numbers. The base station notifies the mobile station of information indicating the number of ID numbers which are included in the set of ID numbers. The mobile station acquires, from the base station, the information indicating the number of ID numbers which are included in the set of ID numbers.

摘要： There are provided a technology associated with a terminal device, a base station apparatus, a communication system, a communication method, and an integrated circuit, in all of which efficient communication control is performed. A terminal device makes a connection to a base station apparatus using a first cell group and second cell group, and, in a case where the second cell group that includes at least one cell is changed based on an information element which is notified with a radio resource control message that is received from the base station apparatus, starts counting of an RRC timer relating to a random access procedure for the cell in the second cell group, and initiates the random access.

摘要： A mobile station apparatus receives, on a PDCCH (physical downlink control channel), information used for initiating a random access procedure. The mobile station apparatus also transmits a random access preamble on a physical random access channel resource based on or in response to the information. Furthermore, the mobile station apparatus receives a random access response corresponding to the random access preamble on one specific downlink component carrier among a plurality of downlink component carriers where the one specific downlink component carrier linked to an uplink component carrier on which the random access preamble is transmitted on the physical random access channel resource.
