COMMUNICATION DEVICE AND SRS TRANSMISSION CONTROL METHOD

Abstract

Provided are a communication device and an SRS transmission method capable of reducing the possibility of a difference in recognition between the presence or absence of an SRS transmission between a base station and a terminal or of an SRS resource so as to prevent degradation of system throughput. At a terminal ( 200) a reception processing unit (203) detects control information indicating whether or not to request transmission of a sounding reference signal (SRS) whereupon a transmission signal forming unit (207) transmits an A-SRS by way of control by a transmission control unit (206) on the basis of control information. The transmission control unit (206) determines whether or not to execute SRS transmission on the basis of an SRS Transmission Execution Rule and the reception status of trigger information.

Transmitting/receiving of control channel/control information

Claim

1. A communication apparatus, comprising:
circuitry, which, in operation, detects control information indicating whether transmission of a sounding reference signal (SRS) is requested and indicating a transmission parameter of the SRS, the control information being received from a base station; and
a transmitter, which, in operation, transmits the SRS based on the detected control information, when two or more receptions of the control information, which indicate different transmission parameters, are not detected from the base station within a determined period.
2. The communication apparatus according to claim 1 wherein:
when two or more receptions of the control information are received within the determined period, the two or more receptions of the control information indicate an identical transmission parameter.
3. The communication apparatus according to claim 1 wherein:
when the circuitry detects two or more instances of the control information, which indicate different transmission parameters, within the determined period, the transmitter, in operation, does not transmit the SRS.
4. The communication apparatus according to claim 1 wherein:
the transmitter, in operation, transmits the SRS in first subframe(s) n among subframes, which are located at or after a k-th subframe from a subframe in which the control information requesting the transmission of the SRS is detected, the subframes being configured based on periodicity Np and a subframe offset, and
the determined period is a period from subframe n?(Np?k+1) to subframe n?k.
5. The communication apparatus according to claim 1 wherein the transmitter, in operation, transmits the SRS in a first subframe among subframes, which are located at or after a k-th subframe from a subframe in which the control information requesting the transmission of the SRS is detected, the subframes being configured based on a periodicity and a subframe offset.
6. The communication apparatus according to claim 1 wherein the transmission parameter indicates at least one of a bandwidth, an RB position where the bandwidth starts, a Cyclic Shift, a transmission Comb, a number of antenna ports, and whether frequency hopping is employed.
7. The communication apparatus according to claim 1 wherein the control information is received in one of a plurality of formats, and the transmission parameter is identified based on the format.
8. The communication apparatus according to claim 1 wherein the SRS is an aperiodic SRS triggered by downlink control information.
9. A communication method, comprising:
detecting control information indicating whether transmission of a sounding reference signal (SRS) is requested and indicating a transmission parameter of the SRS, the control information being received from a base station; and
transmitting the SRS based on the detected control information, when two or more receptions of the control information, which indicate different transmission parameters, are not detected from the base station within a determined period.
10. The communication method according to claim 9 wherein:
when two or more receptions of the control information are received within the determined period, the two or more receptions of the control information indicate an identical transmission parameter.
11. The communication method according to claim 9 wherein:
when the circuitry detects two or more instances of the control information, which indicate different transmission parameters, within the determined period, the SRS is not transmitted.
12. The communication method according to claim 9 wherein:
the transmitting includes transmitting of the SRS in first subframe(s) n among subframes, which are located at or after a k-th subframe from a subframe in which the control information requesting the transmission of the SRS is detected, the subframes being configured based on periodicity Np and a subframe offset, and
the determined period is a period from subframe n?(Np?k+1) to subframe n?k.
13. The communication method according to claim 9 wherein the transmitting includes transmitting of the SRS in a first subframe among subframes, which are located at or after a k-th subframe from a subframe in which the control information requesting the transmission of the SRS is detected, the subframes being configured based on a periodicity and a subframe offset.
14. The communication method according to claim 9 wherein the transmission parameter indicates at least one of a bandwidth, an RB position where the bandwidth starts, a Cyclic Shift, a transmission Comb, a number of antenna ports, and whether frequency hopping is employed.
15. The communication method according to claim 9 wherein the control information is received in one of a plurality of formats, and the transmission parameter is identified based on the format.
16. The communication method according to claim 9 wherein the SRS is an aperiodic SRS triggered by downlink control information.
