Abstract: This disclosure provides systems, methods, and apparatuses to enable a user equipment (UE) and a base station to improve reception of a random access response (RAR) by the UE in an unlicensed spectrum. A network may define a procedure for calculating a random access radio network temporary identifier (RA-RNTI) specific to unlicensed spectrum based on an extended RAR window.

Accordingly, a UE may receive the RAR and compare the timing information with its own random access request in order to determine whether the RAR is addressed to the UE. Additionally, a UE may monitor a secondary cell or a sub-band for the RAR.

A user equipment (UE) may identify a full-duplexing rule that indicates to refrain from using a transmission dropping rule for transmission direction conflicts that occur between uplink and downlink transmissions in a same symbol. The UE may receive a control message scheduling transmission of a message during a symbol, where a transmission direction conflict arises between a first transmission direction of the message and a second transmission direction of the symbol. For example, the UE may identify a transmission direction conflict between an uplink transmission direction of the message and a downlink transmission direction of the symbol. The UE may communicate the message during the symbol based on the full-duplexing rule. The described techniques may enable the UE to attain reduced latency and higher throughput based on reducing a number of transmissions dropped by the UE.
