Various embodiments herein provide techniques related to methods or techniques to be performed by a user equipment (UE). In some embodiments, a technique may include identifying that a failure of a listen-before-talk (LBT) procedure is related to alignment with a u-FFP. The technique may further include notifying, based on the identification, a higher layer about the failure of the LBT procedure. Other embodiments may be described and/or claimed.

A user equipment (UE) executes a wireless communication method to harmonize features for NR-based access to unlicensed spectrum (NR-U) and Ultra-reliable low-latency communications (URLLC). The UE comprises a medium access control (MAC) entity. The MAC entity prioritizes autonomous transmission of a pending MAC protocol data unit (PDU) through a first UL grant over transmission of the MAC PDU indicated as new data through a second UL grant when a logical channel (LCH) priority associated with the MAC PDU indicated as new data is not higher than an LCH priority associated with the pending MAC PDU. The MAC entity prioritizes transmission of the MAC PDU indicated as new data through the second UL grant over autonomous transmission of the pending MAC PDU when the LCH priority associated with the MAC PDU indicated as new data is higher than the LCH priority associated with the pending MAC PDU.

Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to perform URLLC scheme selection. The UE may connect to at least one base station. The UE may determine scheduling of a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH) are within a threshold duration. Based on the PDCCH and the PDSCH being scheduled within the threshold duration, select one or more transmission control indicator (TCI) states for receiving the PDSCH irrespective of TCI state(s) indicated in the PDCCH. The UE may receive the PDSCH using the selected one or more TCI states.

This application provides a communication resource scheduling method and an apparatus. The communication resource scheduling method in this application may include: indicating that a first resource of a first cell is used for first transmission, and indicating that a second resource of a neighboring cell of the first cell is used for second transmission, where at least one of time domain, frequency domain, space domain, code domain, or power domain of the second resource is different from at least one of time domain, frequency domain, space domain, code domain, or power domain of the first resource. In embodiments of this application, different scheduling manners may be used for the first cell and the neighboring cell of the first cell, to meet different service requirements of terminal devices in different cells, and avoid uplink and downlink interference while meeting the different service requirements.
