Claim of US Patent No. 9,198,159

1. A transmission method for non-periodic Sounding Reference Symbol (SRS), comprising:
a terminal equipment receiving time-domain configuration parameter of non-periodic SRS sent by eNB through higher layer signalling
or Physical Downlink Control Channel (PDCCH) signalling;

after receiving the non-periodic SRS activation signalling sent by the eNB, the terminal equipment selecting corresponding
time-domain resource to send non-periodic SRS to the eNB in accordance with the time-domain configuration parameter of the
non-periodic SRS, wherein

sending non-periodic SRS directly on all configuration subframes within a time-domain resource configuration periodicity after
several subframes in accordance with the configuration parameter of non-periodic SRS, or

determining to send non-periodic SRS on all configuration subframes within a time-domain resource configuration periodicity
after several subframes in accordance with the duration configuration information of non-periodic SRS carried in higher layer
signalling or PDCCH signalling.
