    Abstract: This disclosure relates to techniques for configuring listen before talk and short control signaling in unlicensed spectrum in a wireless communication system. A wireless device may establish a wireless link with a cellular base station on a cell in unlicensed spectrum. The wireless device may receive listen-before-talk configuration information, where the listen-before-talk configuration information indicates whether listen-before-talk is configured for the wireless link. The wireless device may receive short control signaling configuration information, where the short control signaling configuration information indicates whether short control signaling is enabled for one or more types of control signaling. The wireless device may perform short control signaling with the cellular base station on the wireless link when short control signaling is enabled. The short control signaling performed between the cellular base station and the wireless device may include either or both of uplink transmissions or downlink transmissions.

    Abstract: Apparatuses, systems, and methods for performing dual active protocol stack handovers in a frequency range above 24 GHz. A UE may transmit an indication to a base station indicating a dual active protocol stack (DAPS) handover capability of the UE corresponding to a frequency range (FR) above 24 GHz. The UE may receive, from a target cell of the one or more cells, a command to perform a DAPS handover from a source cell to the target cell. While performing the DAPS handover and maintaining a data connection with the source cell, the UE may perform measurements on the target cell followed by a physical random access channel (PRACH) procedure. The UE may then receive a source cell release command from the target cell and release the data connection with the source cell.

    Abstract: Methods, apparatuses, and systems are disclosed for configuring measurement timings in connection with UEs that are capable of signaling whether a measurement gap (MG) is needed to measure a target frequency carrier. For example, a measurement period may be determined for the target frequency carrier based on the UE indicating that it supports per-frequency range (FR) MGs, and determining that the FR of the target frequency carrier does not include any current serving cell(s). If the UE indicates that no MG is needed to measure the target frequency carrier, then the measurement period may be based on an SMTC, and may be further based on a predefined effective measurement gap repetition period (MGRP). If the UE indicates that a MG is needed, then the measurement period may be based on the SMTC, and may be further based on the effective MGRP or a per-UE MGRP.

    Abstract: This disclosure relates to techniques for aligning wireless device and cellular network expectations and behavior in conjunction with neighbor cell measurements in a wireless communication system. A wireless device may determine that a reference signal is configured for a neighbor cell measurement when communication with the serving cell is also configured. The wireless device may determine whether the reference signal for the neighbor cell measurement is configured with same or different subcarrier spacing as the communication with the serving cell. The wireless device may select one or more of the reference signal for the neighbor cell measurement or the communication with the serving cell to receive based at least in part on whether the reference signal for the neighbor cell measurement is configured with same or different subcarrier spacing as the communication with the serving cell.

    Abstract: A wireless device may establish communication with a network node and determine a relationship between transmission configuration indication (TCI) and bandwidth part (BWP). The wireless device may then receive an indication of one of TCI or BWP from the network node followed by determining the other of TCI or BWP based on the indication and using the relationship between the TCI and BWP. Finally, the wireless device may perform downlink communication using the indicated one of TCI or BWP and determined other TCI or BWP. The network node may be comprised in a non-terrestrial network and may specify via RRC signaling the relationship between TCI and BWP for the wireless device. The indication of the TCI or BWP may be provided by downlink control information (DCI), medium access control (MAC) control element (CE), an inactivity timer, or RRC reconfiguration commands.

    Abstract: Apparatuses, systems, and methods for hybrid measurement gap operation. A network-side device may provide a hybrid measurement gap (MG) configuration to a wireless device, the hybrid measurement gap (MG) configuration scheduling measurement operation of the wireless device in accordance with hybrid measurement gap patterns. The wireless device may receive the hybrid measurement gap (MG) configuration, and thus perform measurement operation based on the hybrid measurement gap patterns as scheduled.
