3 Definitions and abbreviations Word‑p. 8
3.1 Definitions
For the purposes of the present document, the terms and definitions given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
DAPS bearer:
a bearer whose radio protocols are located in both the source eNB and the target eNB during DAPS handover to use both source eNB and target eNB resources.
NB-IoT:
NB-IoT allows access to network services via E-UTRA with a channel bandwidth limited to 200 kHz.
Split bearer:
in dual connectivity, a bearer whose radio protocols are located in both the MeNB and the SeNB to use both MeNB and SeNB resources.
LWA bearer:
in LTE-WLAN Aggregation, a bearer whose radio protocols are located in both the eNB and the WLAN to use both eNB and WLAN resources.
