Abstract
User equipment includes a transmitter configured to transmit a random access preamble or an identifier of the user equipment to a base station apparatus in a two-step random access procedure, a receiver configured to receive a response signal corresponding to at least one of the random access preamble and the identifier of the user equipment, and a downlink signal based on the response signal, from the base station apparatus, and a control unit configured to determine that a contention resolution is successful when information included in the downlink signal matches a part of or all of the identifier of the user equipment.
Claims5
User equipment comprising:
- a transmitter configured to transmit a random access preamble or an identifier of the user equipment to a base station apparatus in a two-step random access procedure;
- a receiver configured to receive a response signal corresponding to at least one of the random access preamble and the identifier of the user equipment, and a downlink signal based on the response signal, from the base station apparatus;
- and
- a control unit configured to determine that a contention resolution is successful when information included in the downlink signal matches a part of or all of the identifier of the user equipment.
A base station apparatus comprising:
- a receiver configured to receive at least one of a random access preamble and an identifier of user equipment from the user equipment in a two-step random access procedure;
- a control unit configured to include a part of or all of the identifier of the user equipment in information included in a downlink signal;
- and
- a transmitter configured to transmit a response signal corresponding to at least one of the random access preamble and an identifier of the base station apparatus, and the downlink signal based on the response signal, to the user equipment.
