摘要： Methods, systems, and devices for wireless communications are described in which UEs may communicate with satellites or base stations, or both in a non-terrestrial network. Due to large distances between transmitting devices and receiving devices in a non-terrestrial network, the UE may account for propagation delay and frequency shift of communications with a satellite based on location information of the satellite. The UE may receive first satellite location information from a base station or a satellite, via a broadcast message. The UE may receive second satellite location information from the wireless network node via a unicast message, where both the first satellite location information and the second satellite location information relate to a same satellite. The UE may transmit an uplink communication via the satellite based on at least one of the first satellite location information or the second satellite location information.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a communication session with a network via a non-terrestrial network (NTN) entity. The UE may receive control signaling identifying one or more measurement trigger criteria for measurements of NTN cells. The UE may receive a reference signal from one or more of the NTN cells. The UE may transmit a message that indicates a measurement of the reference signal associated with at least one of the NTN cells. The UE may perform the measurement of the reference signal in response to one or both of a change in received power associated with the NTN entity satisfying a signal power threshold or at least one of the measurement trigger criteria being satisfied. The described techniques may enable the UE to perform NTN cell measurements with greater efficiency and reduced power consumption, among other benefits.

摘要： Certain aspects of the present disclosure provide techniques for neighbor cell measurements for narrowband communications. An example method generally includes detecting a trigger to take neighbor cell measurements while a user equipment is in a radio resource control (RRC) connected state with a serving cell, based at least in part on a threshold applied to a channel condition metric measured for the serving cell and one or more additional conditions. The method also includes taking neighbor cell measurements in response to detecting the trigger.

摘要： Some techniques and apparatuses described herein enable synchronization of a user equipment (UE) identifier between a UE and a base station upon UE identifier reallocation, which enables the UE to use preconfigured uplink resources to reduce latency, reduce signaling overhead, or the like. For example, some techniques and apparatuses described herein enable the UE to use preconfigured uplink resources when a UE identifier reallocation occurs between preconfigured uplink resource configuration and use of the preconfigured uplink resources by the UE to transmit uplink data.

摘要： Methods, systems, and devices for wireless communications are described. A wireless device, such as a user equipment (UE), may receive a configuration of a page monitoring periodicity, and a configuration of a wake-up signal from a network node, such as a base station. The UE may perform discontinuous monitoring for a plurality of wake-up signals based at least in part on a wake-up signal periodicity, and receive the wake-up signal on the wake-up signal periodicity. The UE may then monitor for paging messages to receive paging information, or updates to system information, during a page monitoring period according to the page monitoring periodicity, the wake-up signal periodicity, the received wake-up signal, or a combination thereof.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a serving cell, signaling identifying a core network type cell ranking offset parameter. The UE may rank, based at least in part on the core network type cell ranking offset parameter, a neighbor cell for reselection relative to the serving cell, wherein the neighbor cell is associated with a different core network type than the serving cell. The UE may selectively reselect to the neighbor cell based at least in part on ranking the neighbor cell for reselection relative to the serving cell. Numerous other aspects are provided.

摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a paging message that includes a secured UE identifier calculated based on a security configuration negotiated between the UE and a trusted source, e.g., a mobility management entity (MME) of the core network. The UE may determine whether the paging message is received from the trusted source or an untrusted source based on the secured UE identifier. The UE may transmit a connection request message based on the determination that the paging message is received from a trusted source.
