SCRAMBLING SEQUENCE GENERATION FOR A MULTI-TRANSMIT RECEIVE POINT CONFIGURATION

Title:

SCRAMBLING SEQUENCE GENERATION FOR A MULTI-TRANSMIT RECEIVE POINT CONFIGURATION

Document Type and Number:

WIPO Patent Application WO/2020/146340

Kind Code:

A3

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmit receive point (TRP), a downlink control information (DCI) communication, the UE being included in a multi-TRP configuration with the first TRP and a second TRP. The UE may determine information unique to the first TRP. The information unique to the first TRP may be at least one of associated with the DCI communication or included in the DCI communication. The UE may generate a downlink scrambling sequence initialization code, associated with the first TRP, based at least in part on the information unique to the first TRP. The UE may generate a downlink scrambling sequence, associated with the first TRP, based at least in part on the downlink scrambling sequence initialization code associated with the first TRP. Numerous other aspects are provided.
