摘要

A mobile station apparatus resets a first parameter or a second parameter, dependent on whether a random access response corresponds to a primary cell or a secondary cell, in a case that the random access response is received, wherein the random access response corresponding to a first serving cell is received in the first serving cell and the random access response corresponding to a second serving cell is received in the second serving cell.

主权项

1. A mobile station apparatus comprising:
transmission circuitry configured to and/or programmed to:
transmit a random access preamble on a first physical random access channel in a first serving cell or on a second physical random access channel in a second serving cell;transmit first control information on a first physical uplink control channel in the first serving cell; andtransmit second control information on a second physical uplink control channel in the second serving cell; reception circuitry configured to and/or programmed to:
receive first physical downlink control channels, each of the first physical downlink control channels including a first downlink control information format including a first transmission power control command for the first physical uplink control channel;receive second physical downlink control channels, each of the second physical downlink control channels including a second downlink control information format including a second transmission power control command for the second physical uplink control channel; andreceive a random access response on a physical downlink shared channel, the random access response corresponding to the random access preamble; and transmission power control circuitry configured to and/or programmed to:
set a first transmission power for transmission of the first physical uplink control channel in a sub-frame by using a first parameter being calculated by accumulating a plurality of first values indicated by the first transmission power control commands; andset a second transmission power for transmission of the second physical uplink control channel in a sub-frame by using a second parameter being calculated by accumulating a plurality of second values indicated by the second transmission power control commands, wherein the transmission power control circuitry further configured to and/or programmed to reset the first parameter or the second parameter, dependent on whether the random access response corresponds to the primary cell or the secondary cell, in a case that the random access response is received, the random access response corresponding to the first serving cell is received in the first serving cell, and the random access response corresponding to the second serving cell is received in the second serving cell.
