Embodiments of the present disclosure provide techniques for determining synchronization signal (SS)/physical broadcast channel (PBCH) block (SSB)-based measurement timing configuration (SMTC) for measurement objects for which a user equipment is to measure feedback information in one or more measurement gaps. Other embodiments may be described and claimed.

A method for establishing a wireless connection between a user equipment (UE) device and a base station in unlicensed radio frequency (RF) spectrum includes (a) receiving, at the UE device, a plurality of RF beams broadcasted by the base station, (b) identifying a selected RF beam of the plurality of RF beams having control information with a maximum received signal level, and (c) identifying a first channel occupancy time (COT1) of the base station from control information of the selected RF beam.

Systems and methods in which devices synchronize their clocks for purposes of data transmission are described. Particularly, the disclosed systems and methods provide detection and mitigation of interference by malicious (or non-malicious) wireless devices with communication of time synchronized data over wireless networks. Systems and methods are provided where times statistics related to multiple instances of wireless time synchronization are collected and collated. Devices in the system can discipline their internal clocks based on the collated time statistics.

Aspects provide a mechanism for activating a secondary serving cell (SCell) in a wireless communication network supporting a multi-cell transmission environment. In some examples, a scheduled entity (e.g., a UE) in a connected mode with a primary serving cell (PCell) may synchronize with the SCell to activate the SCell for multi-cell communication with the PCell and the SCell. To enable synchronization with the SCell, the PCell may trigger communication and processing of one or more reference signals between the scheduled entity and the SCell.

Disclosed is a method and device for indicating a random access physical resource, which may include: semi-statically configuring an internal structure of a random access slot through a broadcast channel. A computer-readable storage medium is further provided in the present disclosure.

Embodiments include methods performed by a second network node in a wireless communications network that includes a first network node, the second network node, and a third network node. Such methods include receiving, from the first network node, a configuration comprising a pattern indicative of whether or not each of a plurality of Synchronization Signal Block (SSB) transmissions, that are configured based on a nominal timing, are actually transmitted by the third network node according to the nominal timing. Such methods include, based on the received configuration, managing transmission and/or reception configurations for one or more of the following: one or more cells served by the second network node; and one or more UEs served by the second network node via the one or more cells. Other embodiments include second network nodes configured to perform such methods.

Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

A method by which a base station transmits a synchronization signal (SS) in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: generating an SS including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS); and transmitting the synchronization signal. A portion of the synchronization signal is transmitted in a region of a time interval corresponding to the cyclic prefix (CP) of the synchronization signal, and the portion of the synchronization signal includes the PSS and/or the SSS.

The disclosure relates to a 5th generation (5G) or 6th (6G) communication system for supporting higher data rates. A method performed by a 5G core network (5GC) entity for timing synchronization, in a wireless communication system includes transmitting, to an access and mobility management function (AMF), subscription information including location information of at least one of an application function (AF) or a base station, receiving, from the AMF, information on a user equipment (UE) identified based on the location information, identifying a sync status for providing a synchronization service, based on the location information and the information on the UE, and transmitting, to a policy and charging function (PCF), information on the sync status.

Enhanced inter-RAT communication operations are disclosed. In one aspect, a device may identify one or more trigger events for monitoring control signals of another network for inter-RAT procedures, such as monitoring for one or more synchronization signal blocks (SSBs). In another aspect, the device may perform a comparison of multiple SSBs. In another aspect, the device may identify one or more release conditions for releasing local settings data associated with a customized measurement gap. In another aspect, the device may send the local settings data to a server. In another aspect, the device may send an extended signaling message indicating a timing offset between network devices.
