Abstract
The present invention discloses a transmission method and apparatus for non-periodic SRS. eNB configures time-domain configuration parameter of non-periodic SRS through higher layer signalling or downlink physical control channel signalling; terminal equipment transmits non-periodic SRS in indicated time-domain resource. The application of the technical solution of the embodiments of the present invention can reduce signalling consumption through high layer semi-static configuration of time-domain resource of non-periodic SRS. On one hand, flexible non-periodic SRS time-domain transmission is allowed for terminal equipment which can send non-periodic SRS in multiple subframes, which is featured by low sounding delay and great sounding bandwidth; on the other hand, flexible timing mode is also permitted for terminal equipment which brings little restriction to scheduling.
