TIME-DOMAIN BUNDLING OF SOUNDING REFERENCE SIGNALS

Abstract:

Aspects relate to sounding reference signal (SRS) time-domain bundling. Phase continuity may be maintained across SRS transmissions over multiple SRS occasions to enable a receiver to jointly process these SRS transmissions. In some examples, a user equipment may expect to be configured with SRS transmissions over multiple SRS occasions where SRS configurations for different SRS transmissions over different SRS occasions specify the same parameters. For example, a first SRS configuration for a first SRS transmission over a first SRS occasion may specify a first set of spatial relation information. In addition, a second SRS configuration for a second SRS transmission over a second SRS occasion may specify that same first set of spatial relation information. In this way, phase continuity may be maintained between the first SRS transmission over the first SRS occasion and the second SRS transmission over the second SRS occasion.
