name: DAA
full_form: Detect And Avoid
context: The Aerial UE supports A2X communication which is broadcasting of BRID and DAA messages using NR sidelink. DAA can also be provided via unicast transmissions in NR sidelink. BRID and DAA message transmission is supported in both in-coverage and out-of-coverage scenarios and relies only on UE autonomous resource selection for NR sidelink communication. BRID and DAA follow the QoS framework defined for NR sidelink and dedicated A2X PQI values are stored in table 6.2.4.1-1 of TS 23.256 [60]. The NG-RAN can configure a separate SL Tx resource pool for BRID and DAA. The SL Tx pool selection for A2X is described in TS 38.321 [6], clause 5.22.
description: Detect And Avoid (DAA) is a procedure used in the context of sidelink communication, specifically for broadcasting messages using NR sidelink to enable aerial UEs to detect and avoid collisions or other hazards.
explanation: The text describes DAA as a defined process within the A2X communication framework, focusing on its function of transmitting specific messages via NR sidelink for collision avoidance. This clearly categorizes it as a procedure.
