Claim
1. A method for indicating a sounding reference signal (SRS) configuration, comprising:
generating at least two pieces of downlink control signaling DCI, wherein each of the at least two pieces of DCI comprises a sounding reference signal SRS configuration information element; and transmitting the at least two pieces of DCI in a subframe to a terminal, for using the SRS configuration information elements in the at least two pieces of DCI to jointly indicate an SRS configuration; wherein the at least two pieces of DCI are included in the PDCCH of the subframe; when two SRS configuration information elements of the at least two pieces of DCI indicate same SRS configuration, using the SRS configuration indicated by the two SRS configuration information element.
2. A method for transmitting a sounding reference signal comprising:
receiving at least two pieces of DCI transmitted in a subframe by a radio access device, wherein each of the at least two pieces of DCI comprises a sounding reference signal SRS configuration information element, wherein the at least two pieces of DCI are included in the PDCCH of the subframe; determining an SRS configuration indicated jointly by the SRS configuration information elements in the at least two pieces of DCI; when two SRS configuration information elements of the at least two pieces of DCI indicate same SRS configuration, using the SRS configuration indicated by the two SRS configuration information element.
3. A radio access device, comprising:
a generating module, configured to generate at least two pieces of DCI, wherein each of the at least two pieces of DCI comprises a sounding reference signal SRS configuration information element; and a transmitting module, configured to transmit the at least two pieces of DCI in a subframe to a terminal, so that the SRS configuration information elements in the at least two pieces of DCI are used to jointly indicate an SRS configuration; wherein the at least two pieces of DCI are included in the PDCCH of the subframe; when two SRS configuration information elements of the at least two pieces of DCI indicate same SRS configuration, using the SRS configuration indicated by the two SRS configuration information element.
4. A terminal device, comprising:
a receiving module, configured to receive at least two pieces of DCI transmitted in a subframe by a radio access device, wherein each of the at least two pieces of DCI comprises a sounding reference signal SRS configuration information element; a determining module, configured to determine an SRS configuration indicated jointly by the SRS configuration information elements in the at least two pieces of DCI received by the receiving module; and a transmitting module, configured to transmit an SRS to the radio access device according to the SRS configuration determined by the determining module; wherein the at least two pieces of DCI are included in the PDCCH of the subframe; when two SRS configuration information elements of the at least two pieces of DCI indicate same SRS configuration, using the SRS configuration indicated by the two SRS configuration information element.
