Abstract
Systems, apparatuses, methods, and computer-readable media are provided for SRS configuration for antenna switching and/or carrier switching. The described techniques may be used in multi-TRP and/or single TRP communication. Also described are techniques for beam configuration for SRS with antenna switching. For example, embodiments provide techniques for beam configuration/update for SRS antenna switching considering the beam change signaling received during the antenna switching procedure. Other embodiments may be described and claimed.
Claims21
-25. (canceled)
One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors cause a user equipment (UE) to:
- receive configuration information for a first set of one or more sounding reference signal (SRS) resource sets and a second set of one or more SRS resource sets, wherein the first set is associated with a first transmission-reception point (TRP) and the second set is associated with a second TRP;
- receive a message to activate one or both of the first and second set of SRS resource sets;
- and
- transmit one or more SRSs with antenna switching based on the activated SRS resource sets.
One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors cause a next generation NodeB (gNB) to:
- encode, for transmission to a user equipment (UE), configuration information for a first set of one or more sounding reference signal (SRS) resource sets and a second set of one or more SRS resource sets, wherein the first set is associated with a first transmission-reception point (TRP) and the second set is associated with a second TRP;
- and
- encode a message for transmission to the UE to activate one or both of the first and second set of SRS resource sets for antenna switching.
One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors cause a next generation Node B (gNB) to:
- encode, for transmission to a user equipment (UE), configuration information for a plurality of sounding reference signal (SRS) resource sets associated with a transmission-reception point (TRP) and configured for antenna switching, wherein all SRS resources of the plurality of SRS resource sets have a same transmission configuration indicator (TCI) state;
- and
- receive, from the UE, one or more SRSs with antenna switching based on the configuration information.
