Abstract: A method of wireless communication performed by a first transmission and reception point (TRP), includes receiving a message indicating a measurement of a reference signal (RS) transmitted in a first band to a wireless device or one or more features of a second band estimated by the wireless device. The first TRP may operate in the second band not overlapping the first band, the one or more features comprise one or more of a channel characteristic, a signal strength, or a beam direction of the second band. The method also includes adjusting one or more parameters of the second band in response to receiving the message. The one or more parameters may include one or both of a channel or a beam direction. The method further includes transmitting signals to a user equipment (UE) in the second band according to the one or more adjusted parameters.

Abstract: Certain aspects of the present disclosure provide techniques for synchronization signal block (SSB) patterns with gaps. A method that may be performed by a network entity (e.g., a BS) generally includes determining a synchronization signal block (SSB) pattern that identifies SSB positions for sweeping a set of SSB beams over multiple SSB bursts with gaps between at least some of the SSB positions, wherein the SSB pattern identifies a subset of the set of SSB beams to use per SSB burst. The method generally includes transmitting SSBs over the multiple SSB bursts in accordance with the pattern.
