摘要：
Disclosed are embodiments for reducing likelihood of selecting a cell identified by a Radio Access Network (RAN) Notification Area ID (RNA ID) that is different from that identifying a last or current serving cell so as to avoid an RNA update procedure; reducing Random Access Channel (RACH) transmissions for an RNA update procedure and a mobile originated (MO) data transmission in response to a Radio Resource Control (RRC) triggered RNA update procedure; and selecting a band or beam in a multi-band/beam cellular system that improves RACH efficiency.
