Abstract
A wireless communication terminal apparatus wherein CoMP communication can normally be performed without increasing the overhead of an upstream line control channel. In this apparatus, a spreading unit primarily spreads a response signal by use of a ZAC sequence established by a control unit. A spreading unit secondarily spreads the response signal, to which CP has been added, by use of a block-wise spread code sequence established by the control unit. The control unit controls, in accordance with sequence numbers and a hopping pattern established therein, the circular shift amount of the ZAC sequence to be used for the primary spread in the spreading unit and the block-wise spread code sequence to be used for the secondary spread in the spreading unit. The hopping pattern established in the control unit is a hopping pattern common to a plurality of base stations that CoMP-receive the response signal.

Claim
1. An integrated circuit to control a process, the process comprising:
first-spreading a response signal using a first sequence-defined by one of a plurality of cyclic shifts, wherein said one of the plurality of cyclic shifts varies between symbols according to a cyclic shift hopping pattern set based on a second identity, which is different from a first identity specific to a cell and which is set independently of the first identity; second-spreading the response signal, which is first-spread, using one of a plurality of second sequences that are orthogonal to each other; and transmitting the response signal.
2. The integrated circuit according to claim 1, comprising:
circuitry which, in operation, controls the process; at least one input coupled to the circuitry, wherein the at least one input, in operation, inputs data; and at least one output coupled to the circuitry, wherein the at least one output, in operation, outputs data.
3. The integrated circuit according to claim 1, wherein the cyclic shift hopping pattern is common between a plurality of base stations communicating with a radio communication terminal apparatus.
4. The integrated circuit according to claim 1, wherein, using a difference between slot numbers in a plurality of base stations communicating with a radio communication terminal apparatus, the cyclic shift hopping pattern is adjusted.
5. The integrated circuit according to claim 4, wherein, the cyclic shift hopping pattern is adjusted using a difference between a slot number in a base station, to which a radio communication terminal apparatus belongs, and a slot number in a specific base station apparatus among a plurality of base stations communicating with the radio communication terminal apparatus.
6. The integrated circuit according to claim 1, wherein the second identity is common between a plurality of base stations communicating with a radio communication terminal apparatus.
7. The integrated circuit according to claim 1, wherein the cyclic shift hopping pattern is set based on one of the first identity and the second identity according to a signaling from a base station communicating with a radio communication terminal apparatus.
8. The integrated circuit according to claim 1, wherein a number of bits in the first identity is same as that in the second identity.
9. The integrated circuit according to claim 1, wherein the second identity is not related to a parameter of a downlink.
10. The integrated circuit according to claim 1, wherein the second identity is related to a resource used for transmission of the response signal.
11. An integrated circuit to comprising:
circuitry, which, in operation:
first-spreads a response signal using a first sequence defined by one of a plurality of cyclic shifts, wherein said one of the plurality of cyclic shifts varies between symbols according to a cyclic shift hopping pattern set based on a second identity, which is different from a first identity specific to a cell and which is set independently of the first identity;
second-spreads the response signal, which is first-spread, using one of a plurality of second sequences that are orthogonal to each other; and
control transmission of the response signal.
12. The integrated circuit according to claim 11, comprising:
at least one input coupled to the circuitry, wherein the at least one input, in operation, inputs data; and at least one output coupled to the circuitry, wherein the at least one output, in operation, outputs data.
