Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive, in a first time slot, a cyclic prefix (CP) at a start end of the first time slot, data content, and tail samples at a tail end of the first time slot. The wireless communication device may initiate a gap action, such as switching beams, during receipt of the tail samples, the gap action taking place within a time gap formed by at least the tail samples. The time gap may also include a CP of a second time slot that is subsequent to the first time slot. The wireless communication device may complete the gap action within the time gap. Numerous other aspects are described.
