Abstract: Methods and systems for handling transmissions in a serving cell Discovery Burst Transmission (DBT) window are provided. According to one aspect, a method performed at a User Equipment (UE) comprises receiving a configuration indicating a serving cell DBT window, receiving a configuration for UE-initiated Uplink (UL) transmission, and suppressing UE-initiated UL transmissions during at least a portion of the serving cell DBT window. These transmissions may be suppressed for the entire serving cell DBT window or suppressed while a base station is transmitting SSBs according to an intended transmit pattern. The suppression may start from a beginning of the serving cell DBT window or from a beginning of a first SSB transmission detected by the UE. The UE may rate match around actual transmitted SSBs that are transmitted within the serving cell DBT window due to various constraints including restrictions on channel access.
